Full Text Available OBJECTIVE: Impairments in balance can be a consequence of changes in the motor, sensory, and integrative aspects of motor control. Abnormal sensory reweighting, i.e., the ability to select the most appropriate sensory information to achieve postural stability, may contribute to balance impairment. The Sensory Organization Test is a component of Computerized Dynamic Posturography that evaluates the impact of visual, vestibular, and somatosensory inputs, as well as sensory reweighting, under conditions of sensory conflict. The aim of this study is to compare balance control in hemiparetic patients during the first year post-stroke and in age-matched neurologically normal subjects using the Berg Balance Scale and Computerized Dynamic Posturography. METHODS: We compared the Berg Balance Scale and Sensory Organization Test scores in 21 patients with hemiparesis after first-ever ischemic stroke and in 21 age-matched, neurologically normal subjects. An equilibrium score was defined for each Sensory Organization Test condition. RESULTS: Berg Balance Scale scores were significantly lower in the patients than in the neurologically normal subjects. Equilibrium scores were significantly lower in the patients than in the neurologically normal subjects for those Sensory Organization Test conditions that did not provide appropriate somatosensory information and under conditions of sensory conflict. A history of falls was more frequent in patients with lower equilibrium scores. CONCLUSION: During the first year after a stroke, defective sensory reweighting significantly impacts balance control in hemiparetic patients. These results are important for the planning of effective rehabilitation interventions.

Trunk instability is one of main problems in survivors following stroke. We investigated the effects of weight-shift training (WST) on an unstable surface in sitting position on trunk control, proprioception, and balance in individuals with chronic hemiparetic stroke. Eighteen participants with chronic hemiparetic stroke were recruited and were allocated to either WST or control group. The WST group received a weight-shift training program for 30 min and then received a conventional exercise program for 30 min, while the control group received conventional exercise program for 60 min, five times a week for four weeks for both groups. In this randomized control study, we used three outcome measures: trunk reposition error (TRE), Trunk Impairment Scale (TIS), and Timed Up and Go (TUG) test. TRE was measured by each participant's reposition error to the target angle during his/her active trunk movement. TIS and TUG were examined for trunk control abilities and dynamic balance abilities, respectively. After training, TRE showed significantly greater improvement in the WST group (mean change, 1.67 ± 1.45˚) than the control group (mean change, 0.08 ± 1.05˚). The TIS score was significantly higher in the WST group (mean change, 2.33 ± 1.50) than the control group (mean change, 0.13 ± 0.83). The TUG test also showed a significant improvement in the WST group (mean change, 5.03 ± 1.88 sec) than the control group (mean change, 2.59 ± 1.86 sec). Our findings indicate that weight-shift training is beneficial for improving trunk control and proprioception in patients with chronic hemiparetic stroke.

To demonstrate the effect of rhythmical auditory stimulation in a musical context for gait therapy in hemiparetic stroke patients, when the stimulation is played back measure by measure initiated by the patient's heel-strikes (musical motor feedback). Does this type of musical feedback improve walking more than a less specific gait therapy? The randomized controlled trial considered 23 registered stroke patients. Two groups were created by randomization: the control group received 15 sessions of conventional gait therapy and the test group received 15 therapy sessions with musical motor feedback. Inpatient rehabilitation hospital. Median post-stroke interval was 44 days and the patients were able to walk without technical aids with a speed of approximately 0.71 m/s. Gait velocity, step duration, gait symmetry, stride length and foot rollover path length (heel-on-toe-off distance). The test group showed more mean improvement than the control group: stride length increased by 18% versus 0%, symmetry deviation decreased by 58% versus 20%, walking speed increased by 27% versus 4% and rollover path length increased by 28% versus 11%. Musical motor feedback improves the stroke patient's walk in selected parameters more than conventional gait therapy. A fixed memory in the patient's mind about the song and its timing may stimulate the improvement of gait even without the presence of an external pacemaker.

Motor skill learning is critical in post-stroke motor recovery, but little is known about its underlying neural substrates. Recently, using a new visuomotor skill learning paradigm involving a speed/accuracy trade-off in healthy individuals we identified three subpopulations based on their behavioral trajectories: fitters (in whom improvement in speed or accuracy coincided with deterioration in the other parameter), shifters (in whom speed and/or accuracy improved without degradation of the other parameter), and non-learners. We aimed to identify the neural substrates underlying the first stages of motor skill learning in chronic hemiparetic stroke patients and to determine whether specific neural substrates were recruited in shifters versus fitters. During functional magnetic resonance imaging (fMRI), 23 patients learned the visuomotor skill with their paretic upper limb. In the whole-group analysis, correlation between activation and motor skill learning was restricted to the dorsal prefrontal cortex of the damaged hemisphere (DLPFCdamh: r = -0.82) and the dorsal premotor cortex (PMddamh: r = 0.70); the correlations was much lesser (-0.16 0.25) in the other regions of interest. In a subgroup analysis, significant activation was restricted to bilateral posterior parietal cortices of the fitters and did not correlate with motor skill learning. Conversely, in shifters significant activation occurred in the primary sensorimotor cortexdamh and supplementary motor areadamh and in bilateral PMd where activation changes correlated significantly with motor skill learning (r = 0.91). Finally, resting-state activity acquired before learning showed a higher functional connectivity in the salience network of shifters compared with fitters (qFDR skill learning with the paretic upper limb in chronic hemiparetic stroke patients, with a key role of bilateral PMd.

Objective: We examined the association of weight-bearing asymmetry (WBA between paretic and nonparetic lower limbs during quiet standing with the degree of deviation of hemiplegic gait from normal gait evaluated by the Gillette Gait Index (GGI incorporating 16 distinct clinically important kinematic and temporal parameters in chronic PS patients.Participants and methods: Twenty-two ambulatory patients with chronic stroke aged between 50 and 75 years were included in this study. Fourteen patients had hemiparesis on the nondominant side and 8 on the dominant side. The mean time PS was 2 years and 6 months. The reference group consisted of 22 students from the University of the Third Age presenting no neurological disorders. The examination consisted of posturographic weight-bearing (WB distribution and 3-dimensional gait analyses.Results: A significant positive relationship between WBA and GGI was revealed. Moreover, we observed a significant negative association between WBA and paretic step length and walking speed. With regard to kinematic data, the range of motion of knee flexion and peak dorsiflexion in the swing phase of the paretic leg were significantly negatively associated with WBA.Conclusion: Although further research is needed to determine a causal link between postural control asymmetry and gait disturbance in hemiplegics, our findings support the inclusion of WB measurements between paretic and
Full Text Available Introduction: A proper assessment of gait pattern is a significant aspect in planning the process of teaching gait in hemiparetic post-stroke patients. The Wisconsin Gait Scale (WGS is an observational tool for assessing post-stroke patients’ gait. The aim of the study was to assess test-retest reliability and internal consistency of the WGS and examine correlations between gait assessment made with the WGS and gait speed, Brunnström scale, Ashworth’s scale and the Barthel Index.

The majority of these stretching devices have focused on spasticity of the leg and only a few devices have been developed for spasticity of the wrist and hand. In addition, most of these devices were large and complicated, with less easy applicability for personal use. To investigate the effect of a stretching device for spasticity of the wrist and hand in chronic hemiparetic stroke patients. Prospective single blind randomized controlled clinical trial. Outpatients. Patients were randomly assigned to either the intervention group (11 patients) or the control group (10 patients). The stretching device consisted of a circular shaped plastic plate and five holders to immobilize the fingers. In position 1, finger tips were facing forward, position 2 was 90° external rotation from position 1, and position 3 was 90° external rotation from position 2. Each position was maintained for 4 minutes and a rest period of 1 minute was given, therefore, one session was performed for 14 minutes. The stretching program was conducted 3 sessions/day, 6 days/week for 4 weeks. Spasticity (modified Ashworth scale [MAS]) and motor function (Fugl-Meyer motor assessment [FMA], Active Range of Motion [AROM]) of affected wrist and hand were assessed three times (first assessment; Pre, second assessment; post-2 weeks, third assessment; post-4 weeks). In the intervention group, significant differences in the wrist and hand MAS and FMA were observed between three assessment times (P0.05). In the control group, no differences in MAS, FMA, and AROM were observed between three assessment times (P>0.05). Findings showed that this stretching device was effective in terms of relieving spasticity and functional recovery. This stretching device is effective in spasticity reducing and motor function improvement. Moreover, it is useful to patient because it is easy to use and portable.

To describe a hand-stretching device that was developed for the management of hand spasticity in chronic hemiparetic stroke patients, and the effects of this device on hand spasticity. Fifteen chronic hemiparetic stroke patients with finger flexor spasticity were recruited and randomly assigned to an intervention group (8 patients) or a control group (7 patients). The stretching device consists of a resting hand splint, a finger and thumb stretcher, and a frame. In use, the stretched state was maintained for 10 minutes per exercise session, and the exercise was performed twice daily for 4 weeks. Spasticity of finger flexor muscles in the two groups was assessed 3 times, 4 weeks apart, using the Modified Ashworth Scale (MAS). Patients in the intervention group were assessed twice (pre-1 and pre-2) before and once (post-1) after starting the stretching program. Mean MAS (mMAS) scores at initial evaluations were not significantly different at pre-1 in the intervention group and at 1st assessment in the control group (p>0.05). In addition, no significant differences were observed between mMAS scores at pre-1 and pre-2 in the intervention group (p>0.05). However, mMAS scores at post-1 were significantly lower than that at pre-2 in the intervention group (p0.05). In addition, mMAS scores at post-1 in the intervention group were significantly decreased compared with those at the 3rd assessment in the control group (pspasticity effectively in chronic hemiparetic stroke patients.

The Nintendo® Wii is a simple and affordable virtual therapy alternative. It may be used at home, and it is a motivating recreational activity that provides continuous feedback. However, studies comparing the use of the Nintendo® Wii to conventional physical therapy are needed. To compare the effect of a rehabilitation treatment using the Nintendo® Wii (NW) with conventional physical therapy (CPT) to improve the sensorimotor function and quality of life for post-stroke hemiparetic patients. The present study applied a randomized, blind, and controlled clinical trial. In total, 30 patients with post-stroke hemiparesis were evaluated. A total of 15 patients were randomly assigned to each group. The SF-36 quality of life and Fugl-Meyer scales were used to evaluate the patients. After treatment, the only variable that differed between the groups was the physical functioning domain of the SF-36 in the group that received conventional physical therapy. A significant difference was observed between both groups before and after treatment in terms of the following Fugl-Meyer scale items: passive movement and pain, motor function of the upper limbs (ULs), and balance. The CPT group also showed a significant difference with regard to their UL and lower limb (LL) coordination. The SF-36 scale analysis revealed a significant difference within both groups with regard to the following domains: physical functioning, role limitation due to physical aspects, vitality, and role limitation due to emotional aspects. The NW group also exhibited a significant difference in the mental health domain. The results indicate that both approaches improved the patients' performance in a similar manner. Virtual rehabilitation using the Nintendo Wii® and CPT both effectively treat post-stroke hemiparetic patients by improving passive movement and pain scores, motor function of the upper limb, balance, physical functioning, vitality, and the physical and emotional aspects of role functioning.

To determine the effects of physical therapy on balance, exaggerated muscle tonicity and quality of life on patients with hemiparesis. This quasi-experimental study was conducted in 2011 among male hemiparetic patients secondary to stroke, at a physiotherapy centre in Neyshabur, Iran. Twenty-four patients were randomly assigned to two equal groups representing the cases and the controls.The cases were assigned to do the practical protocol for 4 weeks.To collect the data, Berg Balance Scaling, Modified Ashworth Scale, Barthel Activities of Daily Living Index and demographic questionnaires were used. Paired and un-paired t-tests were used to analyse data. All analyses were done on SPSS 16. The two groups were similar before intervention. Post-test analysis showed that the average balance and quality of life significantly improved (p<0.001) among the cases, and the quadriceps muscle tonicity decreased (p<0.001). Among the controls, there was no significant change between pre-test and post-test readings. Physical therapy can enhance balance and quality of life of hemiparetic patients and reduces their exaggerated muscle tonicity.

We attempted to evaluate the effect of a stretching device for treatment of hand spasticity in chronic stroke patients. We recruited 21 chronic hemiplegic stroke patients with severe finger flexor spasticity and randomly assigned them to the intervention group (10 patients) and control group (11 patients). The stretching device consisted of a resting hand splint, finger stretcher, and frame. The stretching state was maintained for 30 seconds and relaxed for the next 30 seconds. This stretching and relaxation were repeated for 20 minutes (one session). The stretching program was practiced 2 sessions/day and 6 days/week for 3 weeks for the patients of the intervention group. The effect of this stretching device was assessed using the modified Ashworth scale (MAS) score of finger flexor muscles. Patients in both groups were assessed six times within an interval of one week and patients in the intervention group were assessed two times before starting the stretching program. The two-way repeated measures analysis of variance (ANOVA) test for evaluation of the effect of intervention across all time-points between the two groups showed a significant interaction between time and effect of intervention (P 0.05)), and this improved significantly to 1.97 at Inter-1, 1.55 at Inter-2, 1.20 at Inter-3, and 1.97 at Post-1 (P spasticity in chronic stroke patients.

While sensory dysfunction is common in children with hemiparetic cerebral palsy (CP) secondary to perinatal stroke, it is an understudied contributor to disability with limited objective measurement tools. Robotic technology offers the potential to objectively measure complex sensorimotor function but has been understudied in perinatal stroke. The present study aimed to quantify kinesthetic deficits in hemiparetic children with perinatal stroke and determine their association with clinical function. Case-control study. Participants were 6-19 years of age. Stroke participants had MRI confirmed unilateral perinatal arterial ischemic stroke or periventricular venous infarction, and symptomatic hemiparetic cerebral palsy. Participants completed a robotic assessment of upper extremity kinesthesia using a robotic exoskeleton (KINARM). Four kinesthetic parameters (response latency, initial direction error, peak speed ratio, and path length ratio) and their variabilities were measured with and without vision. Robotic outcomes were compared across stroke groups and controls and to clinical measures of sensorimotor function. Forty-three stroke participants (23 arterial, 20 venous, median age 12 years, 42% female) were compared to 106 healthy controls. Stroke cases displayed significantly impaired kinesthesia that remained when vision was restored. Kinesthesia was more impaired in arterial versus venous lesions and correlated with clinical measures. Robotic assessment of kinesthesia is feasible in children with perinatal stroke. Kinesthetic impairment is common and associated with stroke type. Failure to correct with vision suggests sensory network dysfunction.

Brain-machine interface training was developed for upper-extremity rehabilitation for patients with severe hemiparesis. Its clinical application, however, has been limited because of its lack of feasibility in real-world rehabilitation settings. We developed a new compact task-specific brain-machine interface system that enables task-specific training, including reach-and-grasp tasks, and studied its clinical feasibility and effectiveness for upper-extremity motor paralysis in patients with stroke. Prospective beforeâ€"after study. Twenty-six patients with severe chronic hemiparetic stroke. Participants were trained with the brain-machine interface system to pick up and release pegs during 40-min sessions and 40 min of standard occupational therapy per day for 10 days. Fugl-Meyer upper-extremity motor (FMA) and Motor Activity Log-14 amount of use (MAL-AOU) scores were assessed before and after the intervention. To test its feasibility, 4 occupational therapists who operated the system for the first time assessed it with the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST) 2.0. FMA and MAL-AOU scores improved significantly after brain-machine interface training, with the effect sizes being medium and large, respectively (pbrain-machine interface system is feasible for use in real-world clinical settings.
Full Text Available Background: Stroke-related balance and gait deficits contribute to the large number of falls in these patients. This may be due to inappropriate reaction to external forces. Hence, one has to be able to react to external forces with appropriately timed and scaled responses to maintain balance. Therefore it is important to identify which patients have risk of falling and would benefit from fall prevention measures. To accomplish this, valid and reliable clinical scales those are easy to administer are needed. Assessment scales that predict falls have been tested in different populations. The present prospective study compares two simple scales viz. Timed Up and Go test (TUG and Performance Oriented Mobility Test (POMA in fall prediction among patients with sub acute and chronic stroke. Methodos: 50 stroke subjects were asked to perform both the tests viz. TUG and POMA one after another on the date of evaluation or Day 0 and from Day 1 falls are recorded per month up to six months. Both test results were compared for their accuracy. Results: It was found that t = -4.496 which is highly significant at (p=0.00 which proves that there is remarkable difference in means of TUG and POMA. TUG covers 0.970 and POMA covers 0.135 area in the curve and is an established fact that higher area indicates excellent accuracy. The sensitivity and specificity of TUG is 78% and 94% respectively and that of POMA is 90% and 60% respectively. Conclusion: To conclude, we can say that there is significant difference between the Timed Up and Go test and Tinetti‘s Performance Oriented Mobility Assessment score on prediction of fall in Hemiparetic Stroke patients.

Full Text Available OBJECTIVE: Describe the somatosensory function of the affected upper limb of hemiparetic stroke patients and investigate the correlations between measurements of motor and sensory functions in tasks with and without visual deprivation. METHOD: We applied the Fugl-Meyer Assessment (FMA, Nottingham Sensory Assessment (NSA, and several motor and sensory tests: Paper manipulation (PM, Motor Sequences (MS, Reaching and grasping (RG Tests Functional (TF, Tactile Discrimination (TD, Weight Discrimination (WD and Tactile Recognition of Objects (RO. RESULTS: We found moderate correlations between the FMA motor subscale and the tactile sensation score of the NSA. Additionally, the FMA sensitivity was correlated with the NSA total; and performance on the WD test items correlated with the NSA. CONCLUSION: There was a correlation between the sensory and motor functions of the upper limb in chronic hemiparetic stroke patients. Additionally, there was a greater reliance on visual information to compensate for lost sensory-motor skills.

Perinatal stroke causes most hemiparetic cerebral palsy. Ipsilateral connections from nonlesioned hemisphere to affected hand are common. The nonlesioned primary motor cortex (M1) determines function and is a potential therapeutic target but its neurophysiology is poorly understood. We aimed to characterize the neurophysiological properties of the nonlesioned M1 in children with perinatal stroke and their relationship to clinical function. Fifty-two participants with hemiparetic cerebral palsy and magnetic resonance imaging-confirmed perinatal stroke and 40 controls aged 8 to 18 years completed the same transcranial magnetic stimulation (TMS) protocol. Single-pulse TMS to nonlesioned M1 determined rest and active motor thresholds (RMT/AMT), motor-evoked potential (MEP) latencies, and stimulus recruitment curves (SRC: 100%-150% RMT). Paired-pulse TMS evaluated short-latency intracortical inhibition (SICI) and intracortical facilitation (ICF). Ipsilateral (IP) participants (ipsilateral MEP ≥0.05 mV in ≥5/20 trials) were compared with contralateral MEP only, nonipsilateral (NI) participants. Assisting Hand and Melbourne assessments quantified clinical function. Twenty-five IP were compared with 13 NI (n = 38, median age 12 years, 66% male). IP had lower motor function. SRC to unaffected hand were comparable between IP and NI while IP had smaller ipsilateral SRC. Ipsilateral MEP latencies were prolonged (23.5 ± 1.8 vs 22.2 ± 1.5 ms contra, P < .001). Contralateral SICI was different between IP (-42%) and NI (-20%). Ipsilateral SICI was reduced (-20%). Contralateral ICF was comparable between groups (+43%) and ipsilaterally (+43%). Measures correlated between contralateral and ipsilateral sides. Neurophysiology of nonlesioned M1 and its relationship to motor function is measureable in children with perinatal stroke. Correlation of excitability and intracortical circuitry measures between contralateral and ipsilateral sides suggests common control mechanisms.
Conclusion: Footprint method provides fast and inexpensive tool for clinical gait analysis and is suitable for evaluation of hemiparetic patients. Our findings suggest that areas of emphasis for physical therapy of hemiparetic patients should include increasing stride length and decreasing step width and internal rotation of foot ...

Recovery of impaired motor functions following stroke is commonly incomplete in spite of intensive rehabilitation programmes. At 6 months following a stroke up to 60 % of affected individuals still suffer from permanent motor deficits, in particular hemiparetic gait, that are relevant for daily life. Novel innovative therapeutic strategies are needed to enhance the recovery of impaired gait function following stroke. This pilot study has investigated the effectiveness of conventional physiotherapy in comparison to an apparative cyclic movement training over a period of 4 weeks to improve (i) power during a submaximal cyclic movement training of the lower limbs, (ii) cardiac fitness, (iii) balance and gait ability, and (iv) quality of life in stroke patients. In comparison to physiotherapy apparative cyclic movement training improved power, balance, cardiac fitness and quality of life to a greater extent. However, there was a statistically significant difference between both intervention groups only for balance but not for the other parameters assessed. The present pilot study should inspire future research with larger patient cohorts to allow appropriate judgement on the effectiveness of apparative cyclic movement training in stroke rehabilitation. © Georg Thieme Verlag KG Stuttgart · New York.

Ankle foot orthoses (AFO) are commonly used orthotic device in order to restore the ankle foot function and to improve the balance and gait in post-stroke hemiparetic patients. However, there remain some discussions about their effectiveness on long term hemiparetic patients who had mild to moderate spasticity. To investigate the relative effect of prefabricated thermoplastic posterior leaf spring AFO (PLS-AFO) on balance and fall risk. A cross-over interventional study The Department of PMR of a tertiary hospital. Twenty-five chronic post-stroke long duration hemiparetic patients who had Ashworth grade 1-2 spasticity at affected calf muscles and lower limb Brunnstrom stage 2-3 and also able to walk independently without an assistive device. Berg Balance Scale (BERG), and the postural stability test (PST) and the fall risk test (FRT) of Biodex balance systems were used for the assessments. All of the patients were assessed with AFO and without AFO. All assessments were made with footwear. The mean post-stroke duration was 20,32±7,46 months. The BERG scores were 42,12±9,05 without AFO and 47,52±7,77 with AFO; the overall stability scores of FRT were 3,35±1,97 without AFO and 2,69±1,65 with AFO (Pspasticity on their affected lower limb. These results encourage the usage of AFO on long duration hemiparetic patients in order to provide better balance and lesser fall risk.

Stimulation of the femoral nerve in healthy people can facilitate soleus H-reflex and electromyography (EMG) activity. In stroke patients, such facilitation of transmission in spinal pathways linking the quadriceps and soleus muscles is enhanced and related to co-activation of knee and ankle extensors while sitting and walking. Soleus H-reflex facilitation can be depressed by vibration of the quadriceps in healthy people, but the effects of such vibration have never been studied on the abnormal soleus facilitation observed in people after stroke. To determine whether vibration of the quadriceps can modify the enhanced heteronymous facilitation of the soleus muscle observed in people with spastic stroke after femoral nerve stimulation and compare post-vibration effects on soleus facilitation in control and stroke individuals. Modulation of voluntary soleus EMG activity induced by femoral nerve stimulation (2×motor threshold) was assessed before, during and after vibration of the patellar tendon in 10 healthy controls and 17 stroke participants. Voluntary soleus EMG activity was facilitated by femoral nerve stimulation in 4/10 (40%) controls and 11/17 (65%) stroke participants. The level of facilitation was greater in the stroke than control group. Vibration significantly reduced early heteronymous facilitation in both groups (50% of pre-vibration values). However, the delay in recovery of soleus facilitation after vibration was shorter for the stroke than control group. The control condition with the vibrator turned off had no effect on the modulation. Patellar tendon vibration can reduce the facilitation between knee and ankle extensors, which suggests effective presynaptic inhibition but decreased post-activation depression in the lower limb of people after chronic hemiparetic stroke. Further studies are warranted to determine whether such vibration could be used to reduce the abnormal extension synergy of knee and ankle extensors in people after hemiparetic

To describe the extent to which the voluntary movements of hemiparetic stroke patients are restricted to the hemiplegic limb synergies (which are marked by the inability to master individual joint movements) described by Brunnström. The study also aimed to describe the extent to which the synergies are related to functioning. In a prospective observational study design, 64 consecutive hemiparetic stroke patients were assessed with Brunnström's hemiplegic limb synergies, the modified Ashworth scale for spasticity, the Rivermead mobility index, and the Barthel ADL index. Three months after stroke, 8 of the 64 patients were moving completely or partly within the synergies. All patients whose movements were restricted to the synergies also exhibited spasticity. Hemiparetic patients whose movements were restricted to the synergies had significantly worse functioning scores than hemiparetic patients whose movements were not restricted to the synergies although severe disabilities were seen in both groups. Three months after stroke, the voluntary movements of only 13% of hemiparetic stroke patients were restricted to the synergies. The synergies were associated with spasticity and activity limitations. The use of the synergies might only be suitable for a small fraction of hemiparetic patients-namely, those displaying spasticity.

The purpose of this study was to examine the feasibility of core stabilization exercise with real-time feedback on balance and gait function in patients with chronic hemiparetic stroke. Nineteen stroke subjects were enrolled in this study. The patients were randomly divided into the experimental (n = 10) and control groups (n = 9). Subjects in the experimental group performed core stabilization exercise with real-time feedback training for 30 minutes per day during a period of six weeks. Subjects in the control group performed core stabilization exercise during the same period. This study assessed the kinematic parameters using a portable walkway system, and timed up-and-go test. Gait velocity showed significantly greater improvement in the experimental group (7.3 ± 5.0 sec) than in the control group (-0.7 ± 10.6). Stride length showed significantly greater increase in the experimental group (13.2 ± 7.9 on the affected side and 12.6 ± 8.0 on the less affected side) than the control group (3.5 ± 8.7 on the affected side and 3.4 ± 8.5 on the less affected side). After training, change in results on the timed up and go test was significantly greater in the experimental group than in the control group. Core stabilization exercise using real-time feedback produces greater improvement in gait performance in chronic hemiparetic stroke patients than core stabilization exercise only.
Full Text Available Abstract Background Despite intensive investigation, the origins of the neuromuscular abnormalities associated with spasticity are not well understood. In particular, the mechanical properties induced by stretch reflex activity have been especially difficult to study because of a lack of accurate tools separating reflex torque from torque generated by musculo-tendinous structures. The present study addresses this deficit by characterizing the contribution of neural and muscular components to the abnormally high stiffness of the spastic joint. Methods Using system identification techniques, we characterized the neuromuscular abnormalities associated with spasticity of ankle muscles in chronic hemiparetic stroke survivors. In particular, we systematically tracked changes in muscle mechanical properties and in stretch reflex activity during changes in ankle joint angle. Modulation of mechanical properties was assessed by applying perturbations at different initial angles, over the entire range of motion (ROM. Experiments were performed on both paretic and non-paretic sides of stroke survivors, and in healthy controls. Results Both reflex and intrinsic muscle stiffnesses were significantly greater in the spastic/paretic ankle than on the non-paretic side, and these changes were strongly position dependent. The major reflex contributions were observed over the central portion of the angular range, while the intrinsic contributions were most pronounced with the ankle in the dorsiflexed position. Conclusion In spastic ankle muscles, the abnormalities in intrinsic and reflex components of joint torque varied systematically with changing position over the full angular range of motion, indicating that clinical perceptions of increased tone may have quite different origins depending upon the angle where the tests are initiated. Furthermore, reflex stiffness was considerably larger in the non-paretic limb of stroke patients than in healthy control subjects

To evaluate the hippotherapy influence on gait training in post-stroke hemiparetic individuals. The study was constituted of 20 individuals divided into two groups. Group A performed the conventional treatment while group B the conventional treatment along with hippotherapy during 16 weeks. The patients were evaluated by using the Functional Ambulation Category Scale, Fugl-Meyer Scale, only the lower limbs and balance sub items, Berg Balance Scale, and functional assessment of gait (cadence) in the beginning and end of the treatment. Significant improvements were observed in the experimental group including motor impairment in lower limbs (p=0.004), balance, over time (p=0.007) but a significant trend between groups (p=0.056). The gait independence, cadence and speed were not significantly in both groups (p=0.93, 0.69 and 0.44). Hippotherapy associated with conventional physical therapy demonstrates a positive influence in gait training, besides bringing the patients' gait standard closer to normality than the control group.

The objective of this study was to examine the associations of neuromuscular and cardiovascular impairments with the bone strength index of the hemiparetic distal radius epiphysis in chronic stroke survivors. The results showed that grip strength is the most predominant predictor of the bone strength index. The purpose of the study was to examine the associations of neuromuscular and cardiovascular impairments with the bone strength index of the hemiparetic distal radius epiphysis in chronic stroke survivors. Sixty-five chronic stroke survivors and 34 healthy control subjects underwent scanning of the distal radius epiphyseal site on both sides using peripheral quantitative computed tomography to measure trabecular volumetric bone mineral density (vBMD) (mg/cm(3)), total vBMD (mg/cm(3)), total area (mm(2)), and compressive bone strength index (cBSI) (g(2)/cm(4)). Various indicators of neuromuscular (grip strength, spasticity) and cardiovascular function (vascular elasticity, oxygen consumption during 6-min walk test) were evaluated. Analysis of variance revealed a significant main effect of side (p 0.05). Sex-specific analysis yielded similar results. Multiple regression analyses revealed that the cBSI of the hemiparetic distal radius epiphysis had a stronger association with neuromuscular factors than cardiovascular factors. Overall, grip strength was the strongest determinant of the cBSI of the hemiparetic distal radius epiphysis (p radius epiphysis among chronic stroke patients. Future studies should investigate the efficacy of different muscle-strengthening strategies in enhancing bone strength of this skeletal site in the chronic stroke population.

Perinatal stroke causes hemiparetic cerebral palsy and lifelong motor disability. Bilateral motor cortices are key hubs within the motor network and their neurophysiology determines clinical function. Establishing biomarkers of motor cortex function is imperative for developing and evaluating restorative interventional strategies. Proton magnetic resonance spectroscopy (MRS) quantifies metabolite concentrations indicative of underlying neuronal health and metabolism in vivo. We used functional magnetic resonance imaging (MRI)-guided MRS to investigate motor cortex metabolism in children with perinatal stroke. Children aged 6-18 years with MRI-confirmed perinatal stroke and hemiparetic cerebral palsy were recruited from a population-based cohort. Metabolite concentrations were assessed using a PRESS sequence (3T, TE = 30 ms, voxel = 4 cc). Voxel location was guided by functional MRI activations during finger tapping tasks. Spectra were analysed using LCModel. Metabolites were quantified, cerebral spinal fluid corrected and compared between groups (ANCOVA) controlling for age. Associations with clinical motor performance (Assisting Hand, Melbourne, Box-and-Blocks) were assessed. Fifty-two participants were studied (19 arterial, 14 venous, 19 control). Stroke participants demonstrated differences between lesioned and nonlesioned motor cortex N-acetyl-aspartate [NAA mean concentration = 10.8 ± 1.9 vs. 12.0 ± 1.2, P motor cortex NAA and creatine were strongly correlated with motor performance in children with arterial but not venous strokes. Interrogation of motor cortex by fMRI-guided MRS is feasible in children with perinatal stroke. Metabolite differences between hemispheres, stroke types and correlations with motor performance support functional relevance. MRS may be valuable in understanding the neurophysiology of developmental neuroplasticity in cerebral palsy. Hum Brain Mapp 38:1574-1587, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley

The present study compared the Achilles tendon morphological characteristics, plantar flexor toque and passive ankle stiffness between hemiparetic spastic stroke survivors and healthy subjects. The Achilles tendon length was measured at the affected and contralateral limbs of twelve hemiparetic stroke survivors with ankle spasticity and twelve healthy subjects. The ankle was held at three different angles (20° plantar flexion, 0° and maximum dorsiflexion) while an ultrasound system was used to capture images from the Achilles tendon. Active and passive plantar flexor torque production was measured using an isokinetic dynamometer. There was no significant difference in tendon length and Achilles tendon complacency between stroke survivors [affected limb: 20.8 (1.59) cm at 0° and 0.11 (0.09) cm/N; contralateral limb: 20.8 (1.7) cm at 0° and 0.12 (0.08) cm/N] and healthy subjects [20 (2.78) cm at 0° and 0.15 (0.1) cm/N]. The contralateral limb was stronger than the affected limb, while healthy participants presented larger active torque in relation to stroke survivors. There was no significant difference in passive ankle stiffness between the affected [0.43 (0.08) N/°] and the contralateral limb [0.40 (0.11) N/°], but affected limb was significantly stiffer than the healthy subjects [0.32 (0.07) N/°]. The larger passive torque and ankle joint stiffness from stroke survivors with similar Achilles tendon length compared to healthy subjects seem to be unrelated to tendon extensibility.

Proprioception plays important roles in planning and control of limb posture and movement. The impact of proprioceptive deficits on motor function post-stroke has been difficult to elucidate due to limitations in current tests of arm proprioception. Common clinical tests only provide ordinal assessment of proprioceptive integrity (eg. intact, impaired or absent). We introduce a standardized, quantitative method for evaluating proprioception within the arm on a continuous, ratio scale. We demonstrate the approach, which is based on signal detection theory of sensory psychophysics, in two tasks used to characterize motor function after stroke. Hemiparetic stroke survivors and neurologically intact participants attempted to detect displacement- or force-perturbations robotically applied to their arm in a two-interval, two-alternative forced-choice test. A logistic psychometric function parameterized detection of limb perturbations. The shape of this function is determined by two parameters: one corresponds to a signal detection threshold and the other to variability of responses about that threshold. These two parameters define a space in which proprioceptive sensation post-stroke can be compared to that of neurologically-intact people. We used an auditory tone discrimination task to control for potential comprehension, attention and memory deficits. All but one stroke survivor demonstrated competence in performing two-alternative discrimination in the auditory training test. For the remaining stroke survivors, those with clinically identified proprioceptive deficits in the hemiparetic arm or hand had higher detection thresholds and exhibited greater response variability than individuals without proprioceptive deficits. We then identified a normative parameter space determined by the threshold and response variability data collected from neurologically intact participants. By plotting displacement detection performance within this normative space, stroke survivors

Frenkel's ambulatory activity has been routinely employed by physiotherapists for rehabilitation of gait coordination, however, its immediate influence on blood pressure and heart rate has not been investigated. To investigate the acute effect of Frenkel's ambulatory activity on blood pressure and heart rate of chronic hemiparetic stroke survivors. Using a comparative study design, 60 chronic hemiparetic stroke survivors of varying onset of stroke, ≤6, >6-11 and ≥12 months were subjected to a 2-minute Frenkel's ambulatory activity on marked footsteps (from standard adult described footsteps). Participants were assessed for both blood pressure and heart rate before and after the Frenkel's ambulatory activity. Blood pressure and heart rate significantly increased (pFrenkel's ambulatory activity in all the 3 categories of stroke onset above baseline. However, there was no significant difference (p>0.05) across the onsets in both blood pressure and heart rate responses. The outcome of this study indicated that Frenkel's ambulatory activity has the propensity to increase blood pressure and heart rate of hemiparetic stroke survivors irrespective of the onset of stroke. We recommend a pre, within and post-activity monitoring of stroke survivors while subjecting them to Frenkel's ambulatory activity.

Cerebrovascular accident (stroke) often results in impaired motor control and persistent weakness that may lead to chronic disability, including deficits in gait and balance function. Finding ways to restore motor control may help reduce these deficits; however, little is known regarding the capacity or temporal profile of short-term motor adaptations and learning at the hemiparetic ankle. Our objective was to determine the short-term effects of a single session of impedance-controlled ankle robot ("anklebot") training on paretic ankle motor control in chronic stroke. This was a double-arm pilot study on a convenience sample of participants with chronic stroke (n = 7) who had residual hemiparetic deficits and an equal number of age- and sex-matched nondisabled control subjects. Training consisted of participants in each group playing a target-based video game with the anklebot for an hour, for a total of 560 movement repetitions in dorsiflexion/plantar flexion ranges followed by retest 48 hours later. Task difficulty was adjusted to ankle range of motion, with robotic assistance decreased incrementally across training. Assessments included robotic measures of ankle motor control on unassisted trials before and after training and at 48 hours after training. Following exposure to the task, subjects with stroke improved paretic ankle motor control across a single training session as indexed by increased targeting accuracy (21.6 +/- 8.0 to 31.4 +/- 4.8, p = 0.05), higher angular speeds (mean: 4.7 +/- 1.5 degrees/s to 6.5 +/- 2.6 degrees/s, p jerk: 654.1 +/- 103.3 s(-2) to 537.6 +/- 86.7 s(-2), p control metrics were retained (p > 0.05) at 48 hours in both groups. Robust maintenance of motor adaptation in the robot-trained paretic ankle over 48 hours may be indicative of short-term motor learning. Our initial results suggest that the anklebot may be a flexible motor learning platform with the potential to detect rapid changes in ankle motor performance poststroke.

Aberrant vestibular nuclear function is proposed to be a principle driver of limb muscle spasticity after stroke. We sought to determine whether altered cortical modulation of descending vestibulospinal pathways post-stroke could impact the excitability of biceps brachii motoneurons. Twelve chronic hemispheric stroke survivors aged 46-68 years were enrolled. Sound evoked biceps myogenic potentials (SEBMPs) were recorded from the spastic and contralateral biceps muscles using surface EMG electrodes. We assessed the impact of descending vestibulospinal pathways on biceps muscle activity and evaluated the relationship between vestibular function and the severity of spasticity. Spastic SEBMP responses were recorded in 11/12 subjects. Almost 60% of stroke subjects showed evoked responses solely on the spastic side. These data strongly support the idea that vestibular drive is asymmetrically distributed to biceps motoneuron pools in hemiparetic spastic stroke survivors. This abnormal vestibular drive is very likely to be a factor mediating the striking differences in motoneuron excitability between the clinically affected and clinically spared sides. This study extends our previous observations on vestibular nuclear changes following hemispheric stroke and potentially sheds light on the underlying mechanisms of post-stroke spasticity.

Cortical damage after stroke can drastically impair sensory and motor function of the upper limb, affecting the execution of activities of daily living and quality of life. Motor impairment after stroke has been thoroughly studied, however sensory impairment and its relation to movement control has received less attention. Integrity of the somatosensory system is essential for feedback control of human movement, and compromised integrity due to stroke has been linked to sensory impairment. The goal of this study is to assess the integrity of the somatosensory system in individuals with chronic hemiparetic stroke with different levels of sensory impairment, through a combination of robotic joint manipulation and high-density electroencephalogram (EEG). A robotic wrist manipulator applied continuous periodic disturbances to the affected limb, providing somatosensory (proprioceptive and tactile) stimulation while challenging task execution. The integrity of the somatosensory system was evaluated during passive and active tasks, defined as 'relaxed wrist' and 'maintaining 20% maximum wrist flexion', respectively. The evoked cortical responses in the EEG were quantified using the power in the averaged responses and their signal-to-noise ratio. Thirty individuals with chronic hemiparetic stroke and ten unimpaired individuals without stroke participated in this study. Participants with stroke were classified as having severe, mild, or no sensory impairment, based on the Erasmus modification of the Nottingham Sensory Assessment. Under passive conditions, wrist manipulation resulted in contralateral cortical responses in unimpaired and chronic stroke participants with mild and no sensory impairment. In participants with severe sensory impairment the cortical responses were strongly reduced in amplitude, which related to anatomical damage. Under active conditions, participants with mild sensory impairment showed reduced responses compared to the passive condition, whereas
Full Text Available Stroke is a non-traumatic brain injury caused by occlusion or rupture of cerebral blood vessels that results in sudden neurological deficit characterized by loss of motor control, altered sensation, cognitive or language impairment, disequilibrium, or coma. Immobilization is an important risk factor for osteoporosis. The aim of this study was to compare between affected and non-affected side’s calcaneal bone mineral density in chronic hemiparetic patients. Thirty-tree unilateral and independently mobile hemiparetic patients due to stroke were included in the study. The exclusion criteria were to have poor general health status, bilateral involvement, congenital dislocation of hip and past calcaneal fracture history. Motor functional level, spasticity and daily living activities of the patients were assessed by using Brunstrom, Ashworth and Barthel scales, respectively. The calcaneal bone mineral density was evaluated with DXL-Calscan in both affected and non-affected side of all patients. Patients’ mean age and duration of disease were 58.9±11.9 years and 20±19.4 months, respectively. 48.5% of patients were male and 60.6% has right side hemiparesis. Their mean spasticity level was 1.6±1.2 according to Ashworth Scale. Mean motor functional level and activity of daily living score were 4.5±1 and 87.4±22.2, respectively. The calcaneal mean T score was –2.1±0.9 and –1.7±0.7 in affected and non-affected side, respectively. In the pearson correlation analysis, there were positive correlation between age and non-affected Z score (r=0.42, p=0.01; Brunstrom score and affected side T score (r=0.48, p=0.005; Brunstrom score and affected side BMD (r=0.51, p=0.002. On the other hand, there were negative correlation between age and disease duration (r=-0.36, p=0.03; Ashworth score and Brunstrom (r=-0.66, p=0.0001, affected side T score (r=-0.41, p=0.01, affected side Z score (r=-0.35, p=0.04, affected BMD (r=-0.46, p=0.01. However, there was no

Hybrid assistive neuromuscular dynamic stimulation (HANDS) therapy improved paretic upper extremity motor function in patients with severe to moderate hemiparesis. We hypothesized that brain machine interface (BMI) training would be able to increase paretic finger muscle activity enough to apply HANDS therapy in patients with severe hemiparesis, whose finger extensor was absent. The aim of this study was to assess the efficacy of BMI training followed by HANDS therapy in patients with severe hemiparesis. Twenty-nine patients with chronic stroke who could not extend their paretic fingers were participated this study. We applied BMI training for 10 days at 40 min per day. The BMI detected the patients' motor imagery of paretic finger extension with event-related desynchronization (ERD) over the affected primary sensorimotor cortex, recorded with electroencephalography. Patients wore a motor-driven orthosis, which extended their paretic fingers and was triggered with ERD. When muscle activity in their paretic fingers was detected with surface electrodes after 10 days of BMI training, we applied HANDS therapy for the following 3 weeks. In HANDS therapy, participants received closed-loop, electromyogram-controlled, neuromuscular electrical stimulation (NMES) combined with a wrist-hand splint for 3 weeks at 8 hours a day. Before BMI training, after BMI training, after HANDS therapy and 3month after HANDS therapy, we assessed Fugl-Meyer Assessment upper extremity motor score (FMA) and the Motor Activity Log14-Amount of Use (MAL-AOU) score. After 10 days of BMI training, finger extensor activity had appeared in 21 patients. Eighteen of 21 patients then participated in 3 weeks of HANDS therapy. We found a statistically significant improvement in the FMA and the MAL-AOU scores after the BMI training, and further improvement was seen after the HANDS therapy. Combining BMI training with HANDS therapy could be an effective therapeutic strategy for severe UE paralysis after

The ability to ascend and descend a flight of stairs is considered as one of the best predictors of free-living activity and is correlated with domestic extrinsic activity in hemiparetic patients. However, the relationship between timed-stair performance and clinical and biomechanical parameters has never been studied this population. The aim of this study was to determine if performance on the Timed Up and Down Stairs (TUDS) test was related to clinical variables (maximal gait speed, strength and spasticity) and to biomechanical gait parameters (spatio-temporal, kinematic and kinetic gait parameters) in hemiparetic patients. Sixty hemiparetic patients performed the TUDS test, underwent 3D gait-analysis and a clinical assessment. Pearson's correlations and two stepwise multiple linear regression analyses were carried out to identify the parameters which were the most highly correlated with TUDS test performance among the clinical variables and gait parameters on the paretic side. Maximal walking speed on the 10-m walk test and strength of the ankle dorsiflexors were the clinical variables that were the most related to TUDS test performance (63% of variance explained). The percentage of single support phase on the paretic side was the biomechanical gait parameter which was the most related to TUDS test performance (58% of variance explained). The results of this study identified three parameters which predicted the performance to ascend and descend a flight of stairs as fast as possible in hemiparetic patients. Rehabilitation programs which aim to improve stair performance and independence in daily life activities should focus on these three parameters. Copyright © 2013 Elsevier B.V. All rights reserved.

Monitoring natural behavior and activity routines of hemiparetic rehabilitation patients across the day can provide valuable progress information for therapists and patients and contribute to an optimized rehabilitation process. In particular, continuous patient monitoring could add type, frequency and duration of daily life activity routines and hence complement standard clinical scores that are assessed for particular tasks only. Machine learning methods have been applied to infer activity routines from sensor data. However, supervised methods require activity annotations to build recognition models and thus require extensive patient supervision. Discovery methods, including topic models could provide patient routine information and deal with variability in activity and movement performance across patients. Topic models have been used to discover characteristic activity routine patterns of healthy individuals using activity primitives recognized from supervised sensor data. Yet, the applicability of topic models for hemiparetic rehabilitation patients and techniques to derive activity primitives without supervision needs to be addressed. We investigate, 1) whether a topic model-based activity routine discovery framework can infer activity routines of rehabilitation patients from wearable motion sensor data. 2) We compare the performance of our topic model-based activity routine discovery using rule-based and clustering-based activity vocabulary. We analyze the activity routine discovery in a dataset recorded with 11 hemiparetic rehabilitation patients during up to ten full recording days per individual in an ambulatory daycare rehabilitation center using wearable motion sensors attached to both wrists and the non-affected thigh. We introduce and compare rule-based and clustering-based activity vocabulary to process statistical and frequency acceleration features to activity words. Activity words were used for activity routine pattern discovery using topic models

Stroke patients suffer from gait disturbance due to altered leg muscle actions. Many kinesiological studies have investigated muscle actions, but the metabolic activity of muscles in stroke patients remains to be investigated. We therefore evaluated energy consumption in lower extremity muscles during level walking in hemiparetic individuals. Glucose uptake was measured by positron emission tomography (PET) using (18)F-fluorodeoxyglucose ((18)F-FDG) in eight hemiparetic (mean age: 56 years) and 11 healthy (mean age: 26 years) participants. Standardized uptake ratio (SUR) was computed in each muscle to express the (18)F-FDG-uptake level. SUR was compared across gluteal, thigh, and lower leg muscles and across individual muscles within each muscle group. For each muscle, SUR was compared among the paretic limb of hemiparetic participants, the non-paretic limb of hemiparetic participants, and the right limb of healthy participants. In paretic limbs, mean SUR did not differ between the three muscle groups, or between individual muscles within each muscle group. SURs of paretic lower leg muscles and gluteus minimus muscle were significantly smaller than those of non-paretic limb and healthy participants (p limb of hemiparetic participants, SUR of the lower leg muscles was larger than that of the thigh muscles (p muscles were larger in the non-paretic limb of hemiparetic participants, compared to the right limb of healthy participants (p lower extremity muscles during level walking in hemiparetic individuals.

We analyzed spontaneous 180° turning strategies in poststroke hemiparetic patients by using inertial measurement units (IMUs) and the association of turning strategies with risk of falls. We included right paretic (RP) and left paretic (LP) post-stroke patients, and healthy controls (HCs) from a physical and rehabilitation department in France between July 2015 and October 2015. All subjects were right-handed and right-footed for mobilization tasks. Participants were instructed to turn 180° in a self-selected direction after a 10-m walk while wearing three IMUs on their trunk and both feet. We defined three turning patterns based on the number of external steps (pattern I = 1; II = 2-4 steps; and III ≥ 5) and four turning strategies based on the side chosen to turn (healthy or paretic) and the stance limb used during the first step of the turn (healthy or paretic). Falls in the 6 months after measurement were investigated. We included 17 RP [mean (SD) age 57.5 (9.5) years (range 43-73)], 20 LP patients [mean age 60.7 (8.8) years (range 43-63)], and 15 HCs [mean age 56.7 (16.1) years (range 36-83)]. The LP and RP groups behaved similarly in turning patterns, but 90% of LP patients turned spontaneously to the paretic side versus 59% of RP patients. This difference increased with turning strategies: 85% of LP versus 29% of RP patients used strategy 4 (paretic turn side with paretic limb). Patients using strategy 4 had the highest rate of falls. We propose to consider spontaneous turning strategies as new indicators to evaluate the risk of fall after stroke. IMU could be routinely used to identify this risk and guide balance rehabilitation programs.

Motor recovery of the hand usually plateaus in chronic stroke patients. Various conventional and contemporary approaches have been used to rehabilitate the hand post-stroke. However, the evidence for their effectiveness is still limited. To compare the hand therapy protocols based on Brunnstrom approach and motor relearning program in rehabilitation of the hand of chronic stroke patients. Randomized trial. Outpatients attending the occupational therapy department of a rehabilitation institute. 30 post-stroke subjects (35.06 ± 14.52 months) were randomly assigned into two equal groups (Group A and Group B), Outcome Measures: Brunnstrom recovery stages of hand (BRS-H), Fugl-Meyer assessment: wrist and hand (FMA-WH). Group A received Brunnstrom hand manipulation (BHM). BHM is the hand treatment protocol of the Brunnstrom movement therapy, which uses synergies and reflexes to develop voluntary motor control. Group B received the Motor Relearning Program (MRP) based hand protocol. MRP is the practice of specific motor skills, which results in the ability to perform a task. Active practice of context-specific motor task such as reaching and grasping helps regain the lost motor functions. Both the therapy protocols were effective in rehabilitation of the hand (BRS-H; p = 0.003 to 0.004, FMA-WH; p hand motor recovery) (p hand in chronic post-stroke patients.

To investigate the relationship of white matter integrity and path of the corticospinal tract (CST) on arm function before and after constraint-induced (CI) movement therapy in children with hemiparetic cerebral palsy (CP) and adults with chronic stroke. Study 1 used a multiple-baseline pre-post design. Study 2 was a randomized controlled trial. Outpatient rehabilitation laboratory. Study 1 included children with hemiparetic CP (n=10; mean age ± SD, 3.2±1.7y). Study 2 included adults with chronic stroke (n=26; mean age ± SD, 65.4±13.6y) who received either CI therapy or a comparison therapy. Children in study 1 received CI therapy for 3.5h/d for 15 consecutive weekdays. Adults in study 2 received either CI therapy or a comparison therapy for 3.5h/d for 10 consecutive weekdays. Diffusion tensor imaging was performed to quantify white matter integrity. Motor ability was assessed in children using the Pediatric Motor Activity Log-Revised and Pediatric Arm Function Test, and in adults with the Motor Activity Log and Wolf Motor Function Test. Participants in both studies improved in real-world arm function and motor capacity. Children and adults with disrupted/displaced CSTs and children with reduced fractional anisotropy values were worse on pretreatment tests of motor function than participants with unaltered CSTs. However, neither integrity (fractional anisotropy) nor distorted or disrupted path of the CST affected motor improvement after treatment. Participants who had reduced integrity, displacement, or interruption of their CST performed worse on pretreatment motor testing. However, this had no effect on their ability to benefit from CI therapy. The results for children and adults are consistent with one another.

Full Text Available Stroke is the leading cause of upper limb impairments resulting in disability. Modern rehabilitation includes training with robotic exoskeletons and functional electrical stimulation (FES. However, there is a gap in knowledge to define the detailed use of FES in stroke rehabilitation. In this paper, we explore applying closed-loop FES to the upper extremities (UE of healthy volunteers and individuals with a hemiparetic arm resulting from stroke. We used a set of gyroscopes to monitor arm movements and used a non-linear controller, namely the robust integral of the sign of the error (RISE, to assess the viability of controlling FES in closed-loop. Further, we explored the application of closed-loop FES in improving functional tasks performed by individuals with stroke. Four healthy individuals of ages 27 to 32 years old and five individuals with stroke of ages 61 to 83 years old participated in this study. We used the Rehastim FES unit (Hasomed Ltd. with real-time modulation of pulse width and amplitude. Both healthy and stroke individuals were tested in RISE controlled single and multi-joint upper limb motions following first a sinusoidal trajectory. Individuals with stroke were also asked to perform the following functional tasks: picking up a basket, picking and placing an object on a table, cutting a pizza, pulling back a chair, eating with a spoon, as well as using a stapler and grasping a pen. Healthy individuals were instructed to keep their arm relaxed during the experiment. Most individuals with stroke were able to follow the sinusoid trajectories with their arm joints under the sole excitation of the closed-loop controlled FES. One individual with stroke who was unable to perform any of the functional tasks independently, succeeded in completing all the tasks when FES was used. Three other individuals with stroke, who were unable to complete a few tasks independently, completed some of them when FES was used. The remaining stroke

Hemiparesis is the commonest disabling deficit caused by stroke. In animals, dextroamphetamine (AMPH) paired with training enhances motor recovery, but its clinical efficacy is uncertain. In a randomized, double-blind, placebo-controlled trial, 71 stroke patients were stratified by hemiparesis severity and randomly assigned to 10 sessions of physiotherapy coupled with either 10 mg AMPH or placebo. Study treatments were administered by 1 physiotherapist, beginning 5 to 10 days after stroke and continuing twice per week for 5 weeks. Outcomes were assessed by 1 physiotherapist at baseline, after each treatment session, at 6 weeks, and at 3 months. The primary outcome was motor recovery (impairment level) on the Fugl-Meyer (FM) scale. Secondary outcomes assessed mobility, ambulation, arm/hand function, and independence in activities of daily living. Baseline hemiparesis was severe overall (mean FM score 27.7+/-20.0). Motor scores improved during treatment in both groups (mean change, baseline to 3 months 29.5+/-16.6). Repeated-measures ANOVA revealed no significant differences in recovery between the treatment groups for the entire cohort (n=67) or for subgroups with a severe hemiparesis (n=43), moderate hemiparesis (n=24), or cortically based stroke (n=26). In the moderate subgroup, there was a significant drug x time interaction for upper extremity motor recovery (F=5.14; Pstroke patients with a severe motor deficit, 10 mg AMPH coupled with physiotherapy twice per week for 5 weeks in the early poststroke period provided no additional benefit in motor or functional recovery compared with physiotherapy alone. Patients with moderate severity hemiparesis deserve further investigation. Increased intensity and longer duration drug/therapy dosing regimens should be explored, targeting the upper and lower limbs separately.

Movement impairments about a single joint in stroke patients may be related to deficits in the central regulation of stretch reflex (SR) thresholds of agonist and antagonist muscles. One boundary of the SR threshold range for elbow flexor and extensor muscles was measured in hemiparetic subjects by
Full Text Available Introduction Hemiparesis is a common post-stroke impairment often associated with balance deficits. Standardized instruments for balance assessment may be useful in identifying individuals at risk of falling and evaluating intervention outcomes. Objectives To identify instruments with adequate psychometric properties and clinical application to assess balance in hemiparetic cases within the scope of physiotherapy and to verify tools most frequently used in studies that evaluated the effects of therapeutic interventions in order to improve the balance of hemiparetic patients. Methods A search was conducted in the Medline, Lilacs, PEDro, and Web of Science databases by two independent researchers, who selected and analyzed studies that evaluated the reliability and validity of balance assessment instruments and intervention results. Results and discussion The Berg Balance Scale was the most frequently used instrument in the intervention studies. Nine single-task tests (timed up and go, functional reach test, step test, four-square step test, side step test, supported standing balance, standing arm raise, static tandem standing, and weight shifting and six multiple-task tests (Berg balance scale, Brunel balance assessment, Fugl-Meyer Assessment/balance section, mini balance evaluation systems test, and postural assessment scale for stroke patients demonstrated adequate psychometric properties and clinical applications to assess balance in hemiparetic individuals. Conclusions The Berg Balance Scale had the most widely studied psychometric properties and was the most frequently used scale in the intervention studies. Further studies are required to validate and adapt other instruments for the Brazilian population.

The aim of this paper was to explore how an upper limb exoskeleton can be programmed to impose specific joint coordination patterns during rehabilitation. Based on rationale which emphasizes the importance of the quality of movement coordination in the motor relearning process, a robot controller was developed with the aim of reproducing the individual corrections imposed by a physical therapist on a hemiparetic patient during pointing movements. The approach exploits a description of the joint synergies using principal component analysis (PCA) on joint velocities. This mathematical tool is used both to characterize the patient's movements, with or without the assistance of a physical therapist, and to program the exoskeleton during active-assisted exercises. An original feature of this controller is that the hand trajectory is not imposed on the patient: only the coordination law is modified. Experiments with hemiparetic patients using this new active-assisted mode were conducted. Obtained results demonstrate that the desired inter-joint coordination was successfully enforced, without significantly modifying the trajectory of the end point.

Postural core instability is associated with poor dynamic balance and a high risk of serious falls. Both neurodevelopmental treatment (NDT) and dynamic neuromuscular stabilization (DNS) core stabilization exercises have been used to improve core stability, but the outcomes of these treatments remain unclear. This study was undertaken to examine the therapeutic effects of NDT and DNS core stabilization exercises on muscular activity, core stability, and core muscle thickness. Ten participants (5 healthy adults; 5 hemiparetic stroke patients) were recruited. Surface electromyography (EMG) was used to determine core muscle activity of the transversus abdominis/internal oblique (TrA/IO), external oblique (EO), and rectus abdominis (RA) muscles. Ultrasound imaging was used to measure transversus abdominals/internal oblique (TrA/IO) thickness, and a pressure biofeedback unit (PBU) was used to measure core stability during the DNS and NDT core exercise conditions. Data are reported as median and range and were compared using nonparametric Mann - Whitney U test and Wilcoxon signed rank test at pNDT core exercise condition, respectively (pNDT core exercise condition in the hemiparetic stroke patient group (pNDT in both healthy and hemiparetic stroke subjects to provide superior deep core muscle activation, core stabilization, and muscle thickness. Moreover, such advantageous therapeutic benefits of the DNS core stabilization exercise over the NDT exercise were more apparent in the hemiparetis stroke patients than normal controls.
The purpose of this study was to examine the incidence, factors, and effects of antiplatelet and anticoagulant agents on sub-acute and chronic ischemic stroke patients during the rehabilitation phase for rates of deep venous thrombosis (DVT) from the perspective for rehabilitation medicine. In this study of 272 patients undergoing rehabilitation for completed cerebral infarction, multiple circumference measurements of calf and thigh along with presence or absence of symptoms (congestion, swelling, skin redness, warmth, pain, pigmentation, fever and/or Homan sign or Luck's sign) documented in the physical examination were recorded in all patients. Patients with these symptoms suggestive of DVT were included for D-dimer assay and venous duplex ultrasonography to confirm presence of DVT. DVT was documented in 24 patients (8.8%), most of whom displayed distal DVT on the hemiparetic side. A significant association was seen between occurrence of DVT and more severe lower limb paresis, manifesting as gait disturbance, severe calf muscle spasticity, use of ankle-foot orthosis (AFO). A significant increase in development of DVT was associated with severe spasticity in hemiparetic calf muscles (odds ratio (OR) 28.2; 95% confidence interval (CI), 6.9-113.5). Cilostazol seemed to be the only effective antiplatelet drug for preventing DVT in cerebral infarction patients. Incidence of DVT in the rehabilitation phase following stroke was not low, which was predominant as distal DVT on the hemiparetic side. Lower limb paresis, gait disturbance, calf muscle spasticity and use of AFO contributed to occurrence of DVT. It is likely that micro-injuries in the venous endothelium due to spasticity and AFO might cause DVT. Cilostazol seems effective for protecting against venous endothelial damage following DVT.

Individuals with stroke have a high incidence of bone fractures and approximately 30% of these fractures occur in the upper extremity. The high risk of falls and the decline in bone and muscle health make the chronic stroke population particularly prone to upper extremity fractures. This was the first study to investigate the bone mineral content (BMC), bone mineral density (BMD), and soft tissue composition of the upper extremities and their relationship to stroke-related impairments in ambulatory individuals with chronic stroke (onset >1 year). Dual-energy X-ray absorptiometry (DXA) was used to acquire total body scans on 56 (22 women) community-dwelling individuals (>or=50 years of age) with chronic stroke. BMC (g) and BMD (g/cm2), lean mass (g), and fat mass (g) for each arm were derived from the total body scans. The paretic upper extremity was evaluated for muscle strength (hand-held dynamometry), impairment of motor function (Fugl-Meyer motor assessment), spasticity (Modified Ashworth Scale), and amount of use of the paretic arm in daily activities (Motor Activity Log). Results showed that the paretic arm had significantly lower BMC (13.8%, Pstrengthening to promote bone health of the paretic arm in individuals with chronic stroke.

Full Text Available Abstract Background and purpose Providing active assistance to complete desired arm movements is a common technique in upper extremity rehabilitation after stroke. Such active assistance may improve recovery by affecting somatosensory input, motor planning, spasticity or soft tissue properties, but it is labor intensive and has not been validated in controlled trials. The purpose of this study was to investigate the effects of robotically administered active-assistive exercise and compare those with free reaching voluntary exercise in improving arm movement ability after chronic stroke. Methods Nineteen individuals at least one year post-stroke were randomized into one of two groups. One group performed 24 sessions of active-assistive reaching exercise with a simple robotic device, while a second group performed a task-matched amount of unassisted reaching. The main outcome measures were range and speed of supported arm movement, range, straightness and smoothness of unsupported reaching, and the Rancho Los Amigos Functional Test of Upper Extremity Function. Results and discussion There were significant improvements with training for range of motion and velocity of supported reaching, straightness of unsupported reaching, and functional movement ability. These improvements were not significantly different between the two training groups. The group that performed unassisted reaching exercise improved the smoothness of their reaching movements more than the robot-assisted group. Conclusion Improvements with both forms of exercise confirmed that repeated, task-related voluntary activation of the damaged motor system is a key stimulus to motor recovery following chronic stroke. Robotically assisting in reaching successfully improved arm movement ability, although it did not provide any detectable, additional value beyond the movement practice that occurred concurrently with it. The inability to detect any additional value of robot-assisted reaching

On a voluntary basis, 10 adolescents with hemiparesis due to cerebral palsy and 11 neurologically healthy control subjects participated in this proof-of-concept pilot study. The aim was to examine the effects of robot-assisted training for the unaffected arm in patients with hemiparetic cerebral palsy. Baseline comparison between the unaffected arm of the hemiparetic patients with cerebral palsy and the dominant arm of healthy control subjects showed significant differences on the Jebsen-Taylor Hand Function test and action planning ability tests. Within-group comparison after ten 30-minute sessions (five days a week for two consecutive weeks) of robot-assisted training for the unaffected arm showed significant improvements in patients with cerebral palsy on the Jebsen-Taylor Hand Function test (performed at both hands) and action planning ability test (evaluated at the unaffected arm). Our findings are in line with previous evidences of action planning deficits at the unaffected arm in patients with hemiparetic cerebral palsy and support the hypothesis that robot-assisted training for the unaffected arm may be useful to improve manual dexterity and action planning in patients with hemiparesis due to cerebral palsy.

Background Functional magnetic resonance imaging (fMRI) appears to be useful for investigating motor recovery after stroke. Some of the potential confounders of brain activation studies, however, could be mitigated through complementary physiological monitoring. Objective To investigate a sensorimotor fMRI battery that included simultaneous measurement of electrodermal activity in subjects with hemiparetic stroke to provide a measure related to the sense of effort during motor performance. Methods Bilateral hand and ankle tasks were performed by 6 patients with stroke (2 subacute, 4 chronic) during imaging with blood oxygen level-dependent (BOLD) fMRI using an event-related design. BOLD percent changes, peak activation, and laterality index values were calculated in the sensorimotor cortex. Electrodermal recordings were made concurrently and used as a regressor. Results Sensorimotor BOLD time series and percent change values provided evidence of an intact motor network in each of these well-recovered patients. During tasks involving the hemiparetic limb, electrodermal activity changes were variable in amplitude, and electrodermal activity time-series data showed significant correlations with fMRI in 3 of 6 patients. No such correlations were observed for control tasks involving the unaffected lower limb. Conclusions Electrodermal activity activation maps implicated the contralesional over the ipsilesional hemisphere, supporting the notion that stroke patients may require higher order motor processing to perform simple tasks. Electrodermal activity recordings may be useful as a physiological marker of differences in effort required during movements of a subject’s hemiparetic compared with the unaffected limb during fMRI studies.

Weight-bearing capacity (WBC) on the hemiparetic leg is crucial for independent walking, and is thus an important outcome to monitor after a stroke. A specific and practical assessment in non-ambulatory patients is not available. This is of importance considering the increasing administration of high intensive gait training for the severely impaired stroke population. The aim was to develop a fast and easy-to-perform assessment for WBC on a foot pressure plate to be used in clinical routine. WBC was assessed in the frontal plane in 30 non-ambulatory patients with subacute stroke and 10 healthy controls under 3 conditions: static, dynamic, and rhythmic. Force-time curves for the hemiparetic leg (patients with stroke) and the non-dominant leg (healthy controls) were normalised as a percentage of body weight (%BW), and the means analysed over 60, 30, and 15 s (static) and the mean of the peak values for 15, 10, 5, 4, and 3 repetition trials (dynamic, rhythmic). The data were tested for discriminative power and reliability. Dynamic and rhythmic tests could discriminate between patients with stroke and healthy controls over all periods (15, 10, 5, 4, and 3 repetitions) (p 0.829] and inter-session reliability (ICC = 0.740) were found for 3 repetitions in the dynamic test with acceptable absolute reliability [standard error of measurement (SEM) <5 %BW, minimal detectable difference (MDD) <12.4 %BW] and no within- or between-test differences (trial 1, p = 0.792; trial 2, p = 0.067; between trials, p = 0.102). Three dynamic repetitions of loading the hemiparetic leg are sufficient to assess WBC in non-ambulatory patients with subacute stroke. This is an important finding regarding the implementation of a fast and easy-to-perform assessment for routine clinical usage in patients with limited standing ability.

[Purpose] This study aimed to observe the effect of kinesio taping on the quality of movement of each arm during a reaching task in patients with right-sided hemiparetic stroke. [Subjects and Methods] Sixteen right-handed participants who had had a right-sided hemiparetic stroke were requested to perform a reaching task with each arm, with and without kinesio taping. A three-dimensional motion analysis system was used to measure peak angular velocity, time to reach peak angular velocity, and movement units during elbow motion. [Results] In the right arm, movements during the reaching task with kinesio taping were faster, smoother, and more efficient than those without kinesio taping. The peak angular velocity increased, and the time to reach peak angular velocity decreased. Movement units decreased significantly. However, in the untaped arm, the movement was slower, rougher, and less efficient. [Conclusion] Kinesio taping provided a positive effect on the reaching movement of the taped arm of right-handed persons who had had a right-sided hemiparetic stroke.

Full Text Available Stroke is one of the major problems in medical and healthcare that can cause severe disability and death of patients especially for older population. Rehabilitation plays an important role in stroke therapy. However, most of the rehabilitative exercises are monotonous and tiring for the patients. For a particular time, they can easily get bored in doing these exercises. The role of patient’s motivation in rehabilitation is vital. Motivation and rehabilitative outcomes are strongly related. Digital games promise to help stroke patients to feel motivated and more engaged in rehabilitative training through motivational gameplay. Most of the commercial games available in the market are not well-designed for stroke patients and their motivational needs in rehabilitation. This study aims at understanding the motivational requirements of stroke patients in doing rehabilitative exercises and living in a post-stroke life. Based on the findings from the literature review, we report factors that can influence the stroke patients’ level of motivation such as social functioning, patient-therapist relationship, goal-setting, and music. These findings are insightful and useful for ideating and designing interactive motivation-driven games for stroke patients. The motivational factors of stroke patients in rehabilitation may help the game designers to design motivation-driven game contexts, contents, and gameplay. Moreover, these findings may also help healthcare professionals who concern stroke patient’s motivation in rehabilitative context. In this paper, we reported our Virtual Nursing Home (VNH concept and the games that we are currently developing and re-designing. Based on this literature review, we will present and test out the ideas how we can integrate these motivational factors in our future game design, development, and enhancement.
Full Text Available Recent neuroimaging studies have demonstrated that stimulation of acupuncture at motor-implicated acupoints modulates activities of brain areas relevant to the processing of motor functions. This study aims to investigate acupuncture-induced changes in effective connectivity among motor areas in hemiparetic stroke patients by using the multivariate Granger causal analysis. A total of 9 stable recovery stroke patients and 8 healthy controls were recruited and underwent three runs of fMRI scan: passive finger movements and resting state before and after manual acupuncture stimuli. Stroke patients showed significantly attenuated effective connectivity between cortical and subcortical areas during passive motor task, which indicates inefficient information transmissions between cortical and subcortical motor-related regions. Acupuncture at motor-implicated acupoints showed specific modulations of motor-related network in stroke patients relative to healthy control subjects. This specific modulation enhanced bidirectionally effective connectivity between the cerebellum and primary sensorimotor cortex in stroke patients, which may compensate for the attenuated effective connectivity between cortical and subcortical areas during passive motor task and, consequently, contribute to improvement of movement coordination and motor learning in subacute stroke patients. Our results suggested that further efficacy studies of acupuncture in motor recovery can focus on the improvement of movement coordination and motor learning during motor rehabilitation.

We investigated the contribution of afferent feedback to the soleus (SOL) muscle activity during the stance phase of walking in patients with spastic stroke. A total of 24 patients with hemiparetic spastic stroke and age-matched healthy volunteers participated in the study. A robotic actuator...... attached to the foot and leg was used to apply 3 types of ankle perturbations during treadmill walking. First, fast dorsiflexion perturbations were applied to elicit stretch reflexes in the SOL muscle. The SOL short-latency stretch reflex was facilitated in the patients (1.4 +/- 0.3) compared...... with the healthy volunteers (1.0 +/- 0.3, P = .05). Second, fast plantar flexion perturbations were applied during the stance phase to unload the plantar flexor muscles, thus, removing the afferent input from these muscles to the SOL motoneurons. These perturbations produced a distinct decrease in SOL activity...
In recent years, our understanding of motor learning, neuroplasticity and functional recovery after the occurrence of brain lesion has grown significantly. Novel findings in basic neuroscience have provided an impetus for research in motor rehabilitation. The brain reveals a spectrum of intrinsic capacities to react as a highly dynamic system which can change the properties of its neural circuits. This brain plasticity can lead to an extreme degree of spontaneous recovery and rehabilitative training may modify and boost the neuronal plasticity processes. Animal studies have extended these findings, providing insight into a broad range of underlying molecular and physiological events. Neuroimaging studies in human patients have provided observations at the systems level that often parallel findings in animals. In general, the best recoveries are associated with the greatest return toward the normal state of brain functional organization. Reorganization of surviving central nervous system elements supports behavioral recovery, for example, through changes in interhemispheric lateralization, activity of association cortices linked to injured zones, and organization of cortical representational maps. Evidence from animal models suggests that both motor learning and cortical stimulation alter intracortical inhibitory circuits and can facilitate long-term potentiation and cortical remodeling. Current researches on the physiology and use of cortical stimulation animal models and in humans with stroke related hemiplegia are reviewed in this article. In particular, electromyography (EMG) -controlled electrical muscle stimulation improves the motor function of the hemiparetic arm and hand. A multi-channel near-infrared spectroscopy (NIRS) studies in which the hemoglobin levels in the brain were non-invasively and dynamically measured during functional activity found that the cerebral blood flow in the injured sensory-motor cortex area is greatest during an EMG-controlled FES

To assess the tolerability and efficacy of a commercially available footdrop neuroprosthesis for treatment of footdrop in children with hemiparetic cerebral palsy. A prospective, observational pilot study. Marshfield Clinic, Department of Physical Medicine. Ten children, ages 7-12 years, with hemiparetic cerebral palsy, who use an ankle foot orthosis (AFO) for correction of footdrop. Children replaced their AFO with a transcutaneous peroneal (fibular) nerve stimulation neuroprosthesis for 3 months. The ability to tolerate fitting and programming of the device, device-recorded wear time, a daily-use diary, satisfaction survey, and secondary measures, including passive range of motion and gait laboratory measurement of gait velocity and ankle kinematics. All 10 participants (100%) tolerated fitting and programming of the neuroprosthesis and wore the device for 6 weeks. Seven of 10 (70%) wore the device for the entire 3-month study period; 6 of 10 (60%) continued to use the device after study completion. Wear time varied from 2 to 11 hours per day. Tolerability and satisfaction were high; although 6 participants complained of "size" and "bulkiness" of the device, and 2 reported skin irritation. Gait velocity increased in 5 subjects (50%). Seven participants (70%) preferred the neuroprosthesis to their AFO. Analysis of the preliminary evidence suggests that electrical stimulation by a footdrop neuroprosthesis is tolerated well by children and is effective for the treatment of footdrop in children with hemiparetic cerebral palsy. Commercially available neuroprostheses may offer a promising alternative treatment option for children with footdrop. Copyright © 2013 American Academy of Physical Medicine and Rehabilitation.

The use of robotic-aided therapy in a patient with residual damage from a previous stroke was an attempt to improve function in a moderate to severe hemiparetic arm. Cortical activities associated with motor recovery are not well documented and require investigation. A chronic stroke patient with a severely affected arm underwent a robotic-training program for 12 weeks. The robotic-aided therapy improved motor control and spasticity in the proximal upper-limb. An increased oxygenated hemoglobin level was observed at the motor-related area in the affected hemisphere. A 12-week robotic-aided training program used in a chronic stroke patient demonstrated elements of motor recovery, and was also associated with direct activation of the affected hemisphere.

The mortality rate of stroke is predicted to be doubled by 2030 in the Middle East countries. Nutrition is an effective strategy in prevention and management of stroke. This study assessed the relationship between various protein types and stroke risk. Materials and Methods: This hospital-based case-control study was performed in a University hospital. The data regarding consumption of usual food intake of 69 cases (46 men and 23 women and 60 controls (30 men and 30 women was collected with a food frequency questionnaire (FFQ. The mean consumption of red and white meat and vegetable and processed proteins consumption were compared between two groups. Results: The percent of total of daily protein intake were lower in patients with stroke in both sexes (25.92% vs 30.55% in men and 30.7% vs 31.14% in women. Conclusion: Lower protein consumption may be observed in patients with stroke patients in both sex.

The movement disorders due to stroke can alter the motion of the Center of Mass (CoM) of the body. Thus, the analysis of the CoM motion can be an alternative to diagnostic the stroke gait disturbances and has not been widely explored. To identify and to analyze the alterations of CoM trajectory during both of gait cycles, affected and unaffected, of post-stroke patients comparing to healthy subjects. The CoM trajectory was obtained using a gold standard method, the three-dimensional (3D) kinematics associate to anthropometry. Two experimental groups were compared: Hemiparetic Group (HG) consisted of fourteen chronic hemiparetic patients and Control Group (CG) by fourteen able-bodied subjects. The statistical analysis (P ≤ 0.05) revealed the following average gait alterations in the HG, in the stance phase of the affected side: higher lateral (midstance), lower vertical (midstance and terminal stance), and lower forward displacement (heel strike until terminal stance). In the swing phase of the affected side, HG showed higher lateral (preswing and initial swing) and vertical displacement (preswing until terminal swing), and lower forward (preswing until terminal swing) displacement of the CoM. There was also anticipation of the instants of maximum displacements in the lateral and vertical directions and lower total range in the forward direction. The CoM trajectory analysis pointed out that the gait after stroke was altered such in the affected as in the unaffected lower limbs, mainly in the single support phase of the affected side, but also in the swing phase of the gait cycle.

Stroke care in Germany has substantially improved during the last decade. One column of modern stroke care is the institution of stroke unit which allows rapid diagnosis and treatment. The aspect of admission of nonstroke patients to a stroke unit is poorly evaluated. The aim of this study is to evaluate the number of patients who are admitted to a national stroke unit but do not suffer from stroke. Furthermore, we related the proportion of nonstroke referrals to the different referral modes. Observational study recording all suspected stroke referrals with regard to final diagnosis and type of referral during a 12-month period (1.8.2002-31.7.2003). 462 patients were admitted by 4 routes: 74 by paramedics or by self-presentation, 138 by emergency physicians, 144 by primary care doctors, and 106 were transferred from other hospitals. 88 patients (19 %) finally revealed no acute stroke. The most common nonstroke diagnoses were seizure (20 %), dissociative disorders (14 %), cranial nerve disorders (11 %), hypoglycaemia (8 %) and transient global amnesia (7 %). There was no significant difference among the proportion of nonstroke patients referred by ambulance paramedics and self-presentation (15 %), emergency physicians (21 %), primary care doctors (15 %) and interhospital transfer (24 %) [p = 0.222, X (2)-test according to Pearson]. Due to the fact that a number of clinical neurological conditions mimic acute stroke, misdiagnosis of stroke is common. We advocate that all stroke patients are seen early in the course of the disease by a neurologist. An alternative could be that in stroke units of internal medicine hospitals patients are seen by a consulting neurologist. Alternatively, telemedicine might be used and the neurologist on duty of a neurological stroke unit could be consulted.

Stroke is a public health problem of the first order. In developed countries is one of the leading causes of death, along with cardiovascular disease and cancer. In addition, stroke is the leading cause of permanent disability in adulthood. Many of the patients who survive do so with significant sequelae that limit them in their activities of daily living. Most strokes (80-85%) are due to ischemia, while the rest are hemorrhagic. We have identified many modifiable risk factors, some with an important relationship with dietary factors or comorbidities in wich the diet has a significant impact. The incidence of malnutrition in stroke patients is not well known, but most likely impacts on patient prognosis. Furthermore, the nutritional status of patients admitted for stroke often deteriorates during hospitalization. It is necessary to perform a nutritional assessment of the patient in the early hours of admission, to determine both the nutritional status and the presence of dysphagia. Dysphagia, through alteration of the safety and efficacy of swallowing, is a complication that has an implication for nutritional support, and must be treated to prevent aspiration pneumonia, which is the leading cause of mortality in the stroke patient. Nutritional support should begin in the early hours. In patients with no or mild dysphagia that can be controlled by modifying the texture of the diet, they will start oral diet and oral nutritional supplementation will be used if the patient does not meet their nutritional requirements. There is no evidence to support the use of nutritional supplements routinely. Patients with severe dysphagia, or decreased level of consciousness will require enteral nutrition. Current evidence indicates that early nutrition should be initiated through a nasogastric tube, with any advantages of early feeding gastrostomy. Gastrostomy will be planned when the enteral nutrition support will be expected for long-term (4 weeks). Much evidence points to the

Although physical problems after stroke have been well studied, there is little information on one of the crucial aspects of the quality of life of those patients, namely sexual functioning and satisfaction. The aim of this study was to assess the impact of stroke on sexual functioning in a stable cohort of Turkish stroke patients with mild or no disability and to assess the relationship between post-stroke sexuality and a number of socio-demographic, clinical and laboratory variables. The sexual functioning of 103 Turkish stroke patients with no disability or mild disability was assessed in two consecutive interviews along with clinical and sociodemographic features. NIH stroke, Glasgow coma, Barthel, and Rankin scales were also applied to assess neurologic status and disability. Most of the patients were male (61%) and illiterate (70%). There was a significant difference between the baseline and post-stroke frequency of sexual activity of the patients. The differences between baseline and post-stroke vaginal lubrication, orgasms and satisfaction were all statistically significant. This latter difference was significant for both genders. Frequency of coitus both prior to and after the stroke was significantly different between males and females. Erection and ejaculation of the males was significantly affected by the stroke, and lubrication and orgasm was affected in the females. Interestingly, fear of recurrent stroke did not differ between genders. Our study has shown that Turkish stroke survivors have sexual health needs during the rehabilitation process, though this has not been addressed previously. Sexual health needs seem to be affected by cultural factors and biases.

Early aggressive rehabilitation therapies maximize functional recovery. We examined patient-reported preferences for their initial rehabilitation therapy setting during their acute stroke hospitalization and whether there was an association between their preferences and their actual discharge destination. Eligible stroke patients were surveyed during their acute hospital stay at either a primary stroke center or a rural community hospital in North Carolina. Patients were questioned about their knowledge of inpatient rehabilitation, preferences for the initial rehabilitation therapy setting and intensity, and how far from home they were willing to travel to receive therapies. The primary outcome was their actual discharge destination. The exposure variable was their preference for initial rehabilitation therapy setting. Logistic regression models assessed the relationship between the outcome and exposure while controlling for other variables of interest. Among 53 patients surveyed in the study, 85% preferred to be discharged home. After controlling for other factors, discharge to the actual destination of home was associated with a preference for an initial rehabilitation therapy setting of home (OR, 7.19; 95% CI, 1.10-46.89). Patient preference for the initial rehabilitation therapy setting is home. Providers should inquire about patient preference and provide information about treatment options to help inform decision making.

Full Text Available The objective of this study was to evaluate the effects of botulinum toxin type A (BTX-A on spastic foot in stroke patients in a rehabilitation program. Method: Hemiparetic stroke patients (n=21 enrolled in a rehabilitation program were divided into two groups. The first group (n=11 received a total of 300UI BTX-A, and the second group (n=10 received 100 UI BTX-A. All patients were assessed at baseline and 2, 4, 8 and 12 weeks after injection for Modified Ashworth Score, time walking 10 meters, and the Functional Independence Measure (mFIM motor score. Results: The higher-dose group exhibited a significant improvement in spasticity, and both groups showed an improvement in time walking 10 meters and mFIM, with no significant differences between them. Conclusions: Our findings suggest that gains in gait velocity and functional independence were not correlated to BTX-A dose.

Full Text Available Introduction. Spasticity is a disabling symptom resulting from reorganization of spinal reflexes no longer inhibited by supraspinal control. Several studies have demonstrated interest in repetitive transcranial magnetic stimulation in spastic patients. We conducted a prospective, randomized, double-blind crossover study on five spastic hemiparetic patients to determine whether this type of stimulation of the premotor cortex can provide a clinical benefit. Material and Methods. Two stimulation frequencies (1 Hz and 10 Hz were tested versus placebo. Patients were assessed clinically, by quantitative analysis of walking and measurement of neuromechanical parameters (H and T reflexes, musculoarticular stiffness of the ankle. Results. No change was observed after placebo and 10 Hz protocols. Clinical parameters were not significantly modified after 1 Hz stimulation, apart from a tendency towards improved recruitment of antagonist muscles on the Fügl-Meyer scale. Only cadence and recurvatum were significantly modified on quantitative analysis of walking. Neuromechanical parameters were modified with significant decreases in Hmax /Mmax and T/Mmax ratios and stiffness indices 9 days or 31 days after initiation of TMS. Conclusion. This preliminary study supports the efficacy of low-frequency TMS to reduce reflex excitability and stiffness of ankle plantar flexors, while clinical signs of spasticity were not significantly modified.
Full Text Available Quantitative evaluation of the hemiparesis status for a poststroke patient is still challenging. This study aims to measure and investigate the dynamic muscle behavior in poststroke hemiparetic gait using ultrasonography. Twelve hemiparetic patients walked on a treadmill, and EMG, joint angle, and ultrasonography were simultaneously recorded for the gastrocnemius medialis muscle. Pennation angle was automatically extracted from ultrasonography using a tracking algorithm reported previously. The characteristics of EMG, joint angle, and pennation angle in gait cycle were calculated for both (affected and unaffected sides of lower limbs. The results suggest that pennation angle could work as an important morphological index to continuous muscle contraction. The change pattern of pennation angle between the affected and unaffected sides is different from that of EMG. These findings indicate that morphological parameter extracted from ultrasonography can provide different information from that provided by EMG for hemiparetic gait.

We devised a therapeutic approach to facilitate the use of the hemiparetic upper extremity (UE) in daily life by combining integrated volitional control electrical stimulation with a wrist splint, called hybrid assistive neuromuscular dynamic stimulation (HANDS). Twenty patients with chronic hemiparetic stroke (median 17.5 months) had moderate to severe UE weakness. Before and immediately after completing 3 weeks of training in 40-minute sessions, 5 days per week over 3 weeks and wearing the system for 8 hours each day, clinical measures of motor impairment, spasticity, and UE functional scores, as well as neurophysiological measures including electromyography activity, reciprocal inhibition, and intracortical inhibition were assessed. A follow-up clinical assessment was performed 3 months later. UE motor function, spasticity, and functional scores improved after the intervention. Neurophysiologically, the intervention induced restoration of presynaptic and long loop inhibitory connections as well as disynaptic reciprocal inhibition. Paired pulse transcranial magnetic stimulation study indicated disinhibition of the short intracortical inhibition in the affected hemisphere. The follow-up assessment showed that improved UE functions were maintained at 3 months. The combination of hand splint and volitional and electrically induced muscle contraction can induce corticospinal plasticity and may offer a promising option for the management of the paretic UE in patients with stroke. A larger sample size with randomized controls is needed to demonstrate effectiveness.

Mechanical properties of an articulated ankle-foot orthosis (AFO) are closely related to gait performance in individuals post-stroke. This paper presents a pilot study on the mechanical properties of a novel articulated AFO with adjustable plantarflexion resistance, dorsiflexion resistance and alignment, and its effect on ankle and knee joint kinematics and kinetics in an individual post-stroke during gait. The mechanical properties of the AFO were quantified. Gait analysis was performed using a 3D motion capture system with a split-belt instrumented treadmill under 12 different settings of the mechanical properties of the AFO [i.e. 4 plantarflexion resistances (P1dorsiflexion resistances (D1dorsiflexion angle changed from 12.01° (D1) to 6.40° (D4) at mid-stance. The novel articulated AFO appeared effective in influencing lower-limb joint kinematics and kinetics of gait in the individual post-stroke. Copyright © 2017 IPEM. Published by Elsevier Ltd.

Elderly people have an increased risk of malnutrition due to biological and physiological changes and underlying disease. Almost 90% of the stroke patients are older than 65 years, and the consequences of acute stroke may lead to additional nutritional problems. This paper reviews nutritional therapy for stroke patients. PubMed was searched (non-systematically) for prospective cohort studies of occurrence, diagnostics and consequences of undernutrition in stroke patients. Randomized trials were examined to identify clinical effects of oral protein and energy supplements or tube feeding on nutritional status and intake, functional status, infections, length of stay, quality of life and mortality. 8-35% of stroke patients are undernourished. Body weight is one of the most important parameters for assessment of nutritional status. Dysphagia occurs in up to 80% of patients with acute stroke and increases the risk of undernutrition, which again leads to prolonged length of stay, reduced functional status and poorer survival. Early nasogastric tube feeding does not increase the risk of pneumonia and may improve survival after six months. Oral supplements lead to a significantly improved nutritional intake in undernourished stroke patients, as well as improved nutritional status and survival in undernourished elderly. Nutritional treatment can improve the clinical outcome after an acute stroke, provided that there are good procedures for follow-up and monitoring of the treatment.
Full Text Available Advanced rehabilitation strategies of the upper limb in stroke patients focus on the recovery of the most important daily activities. In this study we analyzed quantitatively and qualitatively the motor strategies employed by stroke patients when reaching and drinking from a glass. We enrolled 6 hemiparetic poststroke patients and 6 healthy subjects. Motion analysis of the task proposed (reaching for the glass, bringing it to the mouth, and putting it back on the table with the affected limb was performed. Clinical assessment using the Fugl-Meyer Assessment for Upper Extremity was also included. During the reaching for the glass the patients showed a reduced arm elongation and trunk axial rotation due to motor deficit. For this reason, as observed, they carried out compensatory strategies which included trunk forward displacement and head movements. These preliminary data should be considered to address rehabilitation treatment. Moreover, the kinematic analysis protocol developed might represent an outcome measure of upper limb rehabilitation processes.
Avaliação do ácido lático em indivíduos com hemiparesia pós-acidente vascular encefálico após estimulação elétrica para fortalecimento muscular Lactic acid assessment in post-stroke hemiparetic subjects following electrical stimulation for muscle strengthening

Full Text Available O fortalecimento da musculatura parética promove melhora da capacidade funcional, o que pode ser obtido pela estimulação elétrica funcional (EEF, porém são necessários parâmetros específicos para evitar fadiga muscular. Este estudo visou verificar, em indivíduos com hemiparesia pós-AVE, o tempo de repouso (time off necessário para reabsorção do ácido lático durante a EEF, de modo a evitar a fadiga - detectada por lactacidemia (concentração excessiva de ácido lático.

[Purpose] The purpose of this study was to analyze the effects of Pilates exercise on static and dynamic balance in chronic stroke patients. [Subjects and Methods] Nineteen individuals with unilateral chronic hemiparetic stroke (age, 64.7 ± 6.9 years; height, 161.7 ± 7.9 cm; weight, 67.0 ± 11.1 kg) were randomly allocated to either a Pilates exercise group (PG, n=10) or a control group (CG, n=9). The PG attended 24 exercise sessions conducted over an 8-week period (3 sessions/week). Center of pressure (COP) sway and COP velocity were measured one week before and after the exercise program and compared to assess training effects. [Results] Pilates exercise positively affected both static and dynamic balance in patients with chronic stroke. For static balance, COP sway and velocity in the medial-lateral (M-L) and anterior-posterior (A-P) directions were significantly decreased in the PG after training while no significant differences were found in the CG. For dynamic balance, measured during treadmill walking, the PG showed significantly reduced COP sway and velocity in the M-L and A-P directions for both the paretic and non-paretic leg. [Conclusions] The findings provide initial evidence that Pilates exercise can enhance static and dynamic balance in patients with chronic stroke.

Full Text Available Pusher behavior (PB is a disorder of postural control affecting patients with encephalic lesions. This study has aimed to identify the brain substrates that are critical for the occurrence of PB, to analyze the influence of the midline shift (MS and hemorrhagic stroke volume (HSV on the severity and prognosis of the PB. We identified 31 pusher patients of a neurological unit, mean age 67.4±11.89, 61.3% male. Additional neurological and functional examinations were assessed. Neuroimaging workup included measurement of the MS, the HSV in patients with hemorrhagic stroke, the analysis of the vascular territory, etiology and side of the lesion. Lesions in the parietal region (p=0.041 and thalamus (p=0.001 were significantly more frequent in PB patients. Neither the MS nor the HSV were correlated with the PB severity or recovery time.
Full Text Available Stroke is a significant cause of long-term disability world-wide. The post-stroke disabilities are due to loss of locomotion, activity of daily living, cognition and communication skills. Rehabilitation is an integral part of medical management and continues longitudinally through acute care, post-acute care and community reintegration. The objectives of stroke rehabilitation are to maximize the functional independence, minimize the disabilities, reintegrate back into the home and community and improve the self-esteem of patient. A comprehensive stroke rehabilitation service should provide early assessment of impairments and disabilities, management and prevention of complications and well-organized rehabilitation program in both in-patient and out-patient settings. A multidisciplinary or interdisciplinary team approach is necessary to reduce the post-stroke disabilities. It has many members, including physicians, physical therapists, occupational therapists, speech and language pathologists, orthotist, psychotherapists, social workers, vocational rehabilitation therapists, rehabilitation nurse, patients, families and other caregivers. Physicians caring for patients with stroke during rehabilitation must be aware of potential medical complications, as well as a number of special problems that may complicate recovery, including cognitive deficits, aphasia, dysphagia, urinary incontinence, shoulder pain, spasticity, falls and depression. Involvement of patient and caregivers in the rehabilitation process is essential. This article outlines the salient features of the early comprehensive rehabilitation after stroke.

Full Text Available The purpose of this study was to evaluate the somatosensory profile of 18 hemiparetic spastic victims of stroke with and without blocking vision. Maximal isometric contraction test was used for flexor and extensor muscles of the hip and knee, and flexor plantar muscles. The number of cycles per minute on stationary bike was also measured with eyes opened and closed. Significant differences were found suggesting the existence of miscommunication between sensory-motor neural mechanisms responsible for voluntary motor actions in these individuals.

Recent studies using resting-state functional magnetic resonance imaging (rs-fMRI) demonstrated that changes in functional connectivity (FC) after stroke correlate with recovery. The aim of this study was to explore whether combining motor learning to dual transcranial direct current stimulation (dual-tDCS, applied over both primary motor cortices (M1)) modulated FC in stroke patients. Twenty-two chronic hemiparetic stroke patients participated in a baseline rs-fMRI session. One week later, dual-tDCS/sham was applied during motor skill learning (intervention session); one week later, the retention session started with the acquisition of a run of rs-fMRI imaging. The intervention+retention sessions were performed once with dual-tDCS and once with sham in a randomized, cross-over, placebo-controlled, double-blind design. A whole-brain independent component analysis based analysis of variance (ANOVA) demonstrated no changes between baseline and sham sessions in the somatomotor network, whereas a FC increase was observed one week after dual-tDCS compared to baseline (qFDR motor and premotor regions in both hemispheres. At baseline and one week after sham, the strongest FC was observed between the M1 and dorsal premotor cortex (PMd) of the undamaged hemisphere. In contrast, one week after dual-tDCS, the strongest FC was found between the M1 and PMd of the damaged hemisphere. Thus, a single session of dual-tDCS combined with motor skill learning increases FC in the somatomotor network of chronic stroke patients for one week. Copyright © 2016 IBRO.

Full Text Available Not much is known about how well stroke patients are able to perform motor imagery (MI and which MI abilities are preserved after stroke. We therefore applied three different MI tasks (one mental chronometry task, one mental rotation task, and one EEG-based neurofeedback task to a sample of postacute stroke patients (n=20 and age-matched healthy controls (n=20 for addressing the following questions: First, which of the MI tasks indicate impairment in stroke patients and are impairments restricted to the paretic side? Second, is there a relationship between MI impairment and sensory loss or paresis severity? And third, do the results of the different MI tasks converge? Significant differences between the stroke and control groups were found in all three MI tasks. However, only the mental chronometry task and EEG analysis revealed paresis side-specific effects. Moreover, sensitivity loss contributed to a performance drop in the mental rotation task. The findings indicate that although MI abilities may be impaired after stroke, most patients retain their ability for MI EEG-based neurofeedback. Interestingly, performance in the different MI measures did not strongly correlate, neither in stroke patients nor in healthy controls. We conclude that one MI measure is not sufficient to fully assess an individual’s MI abilities.
Full Text Available The aim of this paper was to examine the amount and type of physical activity engaged in by people hospitalised after stroke. Method. We systematically reviewed the literature for observational studies describing the physical activity of stroke patients. Results. Behavioural mapping, video recording and therapist report are used to monitor activity levels in hospitalised stroke patients in the 24 included studies. Most of the patient day is spent inactive (median 48.1%, IQR 39.6%–69.3%, alone (median 53.7%, IQR 44.2%–60.6% and in their bedroom (median 56.5%, IQR 45.2%–72.5%. Approximately one hour per day is spent in physiotherapy (median 63.2 minutes, IQR 36.0–79.5 and occupational therapy (median 57.0 minutes, IQR 25.1–58.5. Even in formal therapy sessions limited time is spent in moderate to high level physical activity. Low levels of physical activity appear more common in patients within 14 days post-stroke and those admitted to conventional care. Conclusions. Physical activity levels are low in hospitalised stroke patients. Improving the description and classification of post stroke physical activity would enhance our ability to pool data across observational studies. The importance of increasing activity levels and the effectiveness of interventions to increase physical activity after stroke need to be tested further.
Full Text Available Abstract Background Stair climbing up and down is an essential part of everyday's mobility. To enable wheelchair-dependent patients the repetitive practice of this task, a novel gait robot, G-EO-Systems (EO, Lat: I walk, based on the end-effector principle, has been designed. The trajectories of the foot plates are freely programmable enabling not only the practice of simulated floor walking but also stair climbing up and down. The article intended to compare lower limb muscle activation patterns of hemiparetic subjects during real floor walking and stairs climbing up, and during the corresponding simulated conditions on the machine, and secondly to demonstrate gait improvement on single case after training on the machine. Methods The muscle activation pattern of seven lower limb muscles of six hemiparetic patients during free and simulated walking on the floor and stair climbing was measured via dynamic electromyography. A non-ambulatory, sub-acute stroke patient additionally trained on the G-EO-Systems every workday for five weeks. Results The muscle activation patterns were comparable during the real and simulated conditions, both on the floor and during stair climbing up. Minor differences, concerning the real and simulated floor walking conditions, were a delayed (prolonged onset (duration of the thigh muscle activation on the machine across all subjects. Concerning stair climbing conditions, the shank muscle activation was more phasic and timely correct in selected patients on the device. The severely affected subject regained walking and stair climbing ability. Conclusions The G-EO-Systems is an interesting new option in gait rehabilitation after stroke. The lower limb muscle activation patterns were comparable, a training thus feasible, and the positive case report warrants further clinical studies.

This clinical study investigates whether the spatial patterns of hemiparetic stroke patients operating a non-invasive Motor Imagery-based Brain Computer Interface (MI-BCI) is comparable to healthy subjects. The spatial patterns for a specific frequency range are generated using the common spatial pattern (CSP) algorithm, of which is highly successful for discriminating two classes of EEG measurements in MI-BCI. The spatial patterns illustrate how the presumed sources project on the scalp and are effective in verifying the neurophysiological plausibility of the computed solution. The spatial patterns show focused activity in ipsilateral as well as contralateral hemisphere with respect to the hand by tapping or motor imagery in 2 BCI-artful healthy subjects and 12 BCI-naïve hemiparetic stroke patients. The results also show that neurophysiologically interpretable spatial patterns is more common in performing motor imagery compared to finger tapping by hemiparetic stroke patients. Hence, this shows that hemiparetic stroke patients are capable of operating MI-BCI.

In the present study, we aimed to determine whether game-based virtual reality (VR) rehabilitation, combined with occupational therapy (OT), could improve health-related quality of life, depression, and upper extremity function. We recruited 35 patients with chronic hemiparetic stroke, and these participants were randomized into groups that underwent VR rehabilitation plus conventional OT, or the same amount of conventional OT alone, for 20 sessions over 4 weeks. Compared to baseline, the VR rehabilitation plus OT group exhibited significantly improved role limitation due to emotional problems (p=0.047). Compared to baseline, both groups also exhibited significantly improved depression (p=0.017) and upper extremity function (p=0.001), although the inter-group differences were not significant. However, a significant inter-group difference was observed for role limitation due to physical problems (p=0.031). Our results indicate that game-based VR rehabilitation has specific effects on health-related quality of life, depression, and upper extremity function among patients with chronic hemiparetic stroke.

Some patients with a recent ischemic stroke who are being treated with aspirin as an antiaggregant suffer a new ischemic stroke. These patients (15-25%) have been called unresponsive to aspirin or aspirin resistant. The aspirin-resistant patients have a four-time greater risk of suffering a stroke. Furthermore, these strokes are generally more severe, with increased infarct volume and greater risk of recurrence. There is currently no ideal laboratory test to detect the resistance to the antiaggregant effect of aspirin. The study of resistance to aspirin would only be indicated in selected cases. In these patients, one should first rule out any "pseudo-resistance" to aspirin (lack of compliance, concomitant treatments that interfere with the action of the aspirin).

Scand J Caring Sci; 2010; 24; 307-311 Stroke patients' delay of emergency treatment Treatment of stroke victims with fibrinolysis should take place within a time limit of 3 hours. In spite of comprehensive endeavours to reduce hospital arrival time, too many patients still delay arrival beyond this time limit. This qualitative case study explored the meaning of acute stroke and treatment to four patients with more than 24-hour delayed arrival. The setting of the study was the catchment area of a university hospital. Semi-structured interviews were analysed through the empirical psychological, phenomenological method. An essence was found which was constituted by four themes. The essence of stroke symptoms and treatment was: 'Threatened control of bodily function, autonomy and integrity'. When the patients fell ill they acted as if nothing had happened. They treated their body like a defective device. In encounters with physicians they demanded to be met as a person by a person; otherwise they rejected both the physician and her or his prescriptions. They did not involve their near ones in decision-making. The conclusions were the following: Health care information about how to act in cases of early stroke symptoms may need to imbue people with an understanding of how early treatment of neurological symptoms and preserved control of life are intimately connected. Furthermore emergency care of acute stroke patients might need to take place in an organisation where patients are sure to be met by physicians as a person by a person.

Diaphragmatic palsy in hemiparetic stroke is not well recognized. Further, its implications on stroke outcome have not been studied. Here, we report a patient with left-sided diaphragmatic palsy due to an acute right middle cerebral artery territory infarction. The diagnosis was suspected on finding an elevated dome of the diaphragm on the left side in a routine chest radiograph and was confirmed by finding decreased movements of the left hemidiaphragm on fluoroscopic examination. We hypothesize that this condition is probably under-recognized in clinical practice and its clinical importance not well known. The pathophysiological basis of diaphragmatic palsy in acute stroke and its possible clinical implications are discussed.

Little was known about the predictive accuracy of the Essen Stroke Risk Score and the Stroke Prognostic Instrument II in Chinese patients with stroke. We evaluated the predictive accuracy of both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores for both recurrent stroke and combined vascular events using data from a prospective cohort of 11 384 patients with acute ischemic stroke and transient ischemic attack admitted to 132 urban hospitals throughout China. The cumulative 1-year event rates were 16% (95% CI, 15%-16%) for recurrent stroke and 18% (95% CI, 18%-19%) for combined vascular events. Both event rates were significantly higher in patients with transient ischemic attack and increased significantly from lower to higher Essen Stroke Risk Score and Stroke Prognostic Instrument II categories. Essen Stroke Risk Score and Stroke Prognostic Instrument II had similar predictive accuracies for each study outcome. In Chinese patients with ischemic stroke or transient ischemic attack, both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores are equally able to stratify the risk of recurrent stroke and combined vascular events.
Full Text Available Introduction: Biological, physical and phsycosocial changes in stroke patient could be a stressor that induced a depression state. There would be an emotional disturbance in stroke patient and stroke attack would be recurrent, if it was not treated. One of the alternative techniques to reduce depression is musical therapy especially memory songs. Method: This study was used a quasy experimental pre-post test purposive sampling design. The population was stroke patients who treated in Neurological Ward A and Stroke Unit Dr Soetomo Hospital Surabaya. There were 12 respondents divided into 6 respondents for treatment group and 6 respondents for control group. The independent variable was music (memory song and dependent variable was depression. Data were collected by using questionnaire which adapted from Hamilton Depression Rating Scale and Geriatric Depression Rating Scale, then analyzed by using Wilcoxon Signed Rank Test and Mann Whitney U Test with significance level α≤0.05. Result: The result showed that there was a difference between pre test and post test in depression (p=0.0196 and there was a difference in the depression between treatment group and control group (p=0.002. Discussion: It can be concluded that music (memory songs has an effect to the depression of stroke patient. Further studies are needed to concerning other factors that may affect the relaxation technique especially in listening music.
Full Text Available OBJECTIVE: To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS: Overnight polysomnography was performed by a computerized system in 19 subjects with ischemic stroke. Patients with an apnea-hypopnea index > 5 were considered to have obstructive sleep apnea. The appropriate level of continuous positive airway pressure for each patient was determined during an all-night continuous positive airway pressure determination study. Attended continuous positive airway pressure titration was performed with a continuous positive airway pressure auto-titrating device. RESULTS: Obstructive sleep apnea prevalence among patients with ischemic stroke was 73.7%. The minimum SaO2 was significantly lower, and the percent of total sleep time in the wake stage and stage 1 sleep was significantly longer in patients with obstructive sleep apnea. In two patients with severe obstructive sleep apnea, we observed a decrease in the apnea-hypopnea index, an increase in mean wake time, mean SaO2, and minimum SaO2, and alterations in sleep structures with continuous positive airway pressure treatment. CONCLUSION: As the diagnosis and treatment of obstructive sleep apnea is of particular importance in secondary stroke prevention, we suggest that the clinical assessment of obstructive sleep apnea be part of the evaluation of stroke patients in rehabilitation units, and early treatment should be started.

Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence. © 2013 Elsevier Inc.

[Purpose] This study examined the effects of trunk exercises performed on an unstable surface on trunk muscle activation, postural control, and gait speed in stroke patients. [Subjects] Twenty-four participants with stroke were recruited in this study and randomly distributed into experimental (n = 12) and control groups (n = 12). [Methods] Subjects in the experimental group participated in trunk exercises on the balance pad for 30 min, five times a week for 4 weeks; those in the control group performed trunk exercises on a stable surface for 30 min, five times a week for 4 weeks. Trunk muscle activation was measured by using surface electromyography, and trunk control was evaluated with the Trunk Impairment Scale (TIS). Gait speed was measured with the 10-Meter Walk Test. [Results] Activity of the external and internal oblique muscles in the experimental group was significantly higher than that in the control group. The TIS score of the experimental group showed significantly greater improvement than did that of the control group. The 10-Meter Walk Test (10MWT) score also significantly improved in the experimental group. [Conclusion] Trunk exercises on an unstable surface improve trunk muscle activation, postural control, and gait speed in patients with hemiparetic stroke.

Stroke is the leading cause of death in women and the third leading cause in men in France. In young adults (ie, stroke was observed at a local scale between 1985 and 2011. After the implementation of the 2010 to 2014 National Stroke Action Plan, this study investigates national trends in patients hospitalized by stroke subtypes, in-hospital mortality, and stroke mortality between 2008 and 2014. Hospitalization data were extracted from the French national hospital discharge databases and mortality data from the French national medical causes of death database. Time trends were tested using a Poisson regression model. From 2008 to 2014, the age-standardized rates of patients hospitalized for ischemic stroke increased by 14.3% in patients stroke was stable (+2.0%), irrespective of age and sex. The proportion of patients hospitalized in stroke units substantially increased. In-hospital mortality decreased by 17.1% in patients with ischemic stroke. From 2008 to 2013, stroke mortality decreased, except for women between 45 and 64 years old and for people aged ≥85 years. An increase in cardiovascular risk factors and improved stroke management may explain the increase in the rates of patients hospitalized for ischemic stroke. The decrease observed for in-hospital stroke mortality may be because of recent improvements in acute-phase management. © 2017 American Heart Association, Inc.

Full Text Available BACKGROUND: We hypothesized that hidden malignancy could be detected in patients with cryptogenic stroke without active cancer when they showed the distinctive characteristics of cancer-related stroke. METHODS AND FINDINGS: Among 2,562 consecutive patients with acute ischemic stroke, patients with cryptogenic stroke were analyzed and categorized into two groups according to the presence of active cancer: cryptogenic stroke with active cancer (cancer-related stroke, CA-stroke group and without active cancer (CR-stroke group. Patients with active lung cancer without stroke were also recruited for comparison purposes (CA-control. Clinical factors, lesion patterns on diffusion-weighted MRI (DWI, and laboratory findings were analyzed among groups. A total of 348 patients with cryptogenic stroke were enrolled in this study. Among them, 71 (20.4% patients had active cancer at the time of stroke. The D-dimer levels were significantly higher in patients with CA-stroke than those with CR-stroke or CA-control (both p<0.001. Regarding lesion patterns, patients with CA-stroke mostly had multiple lesions in multiple vascular territories, while more than 80% of patients with CR-stroke had single/multiple lesions in a single vascular territory (P<0.001. D-dimer levels (OR 1.11 per 1 µg/mL increase; 95% CI 1.06-1.15; P<0.001 and DWI lesion patterns (OR 7.13; 95% CI 3.42-14.87; P<0.001 were independently associated with CA-stroke. Workup for hidden malignancy was performed during hospitalization in 10 patients who showed elevated D-dimer levels and multiple infarcts involving multiple vascular territories but had no known cancer, and it revealed hidden malignancies in all the patients. CONCLUSION: Patients with CA-stroke have distinctive D-dimer levels and lesion patterns. These characteristics can serve as clues to occult cancer in patients with cryptogenic stroke.

Postactivation depression is decreased in patients with spasticity and partially restored by physical exercise in spinal cord injured patients. Up until now, the possibility to modulate postactivation depression with motor training has never been explored in subjects with spasticity following brain lesions. Postactivation depression, assessed as frequency related depression of soleus H-reflex, was investigated before and after robotic-assisted gait training in a group of seven subjects with spastic hemiparesis following hemispheric stroke. Patients received three sessions per week of robotic-assisted gait training for a period of 4 weeks (12 sessions in total). Postactivation depression was measured before the treatment (T0), after the first session (T1) and after the last session (T2). Postactivation depression was quantified as the ratio between H-reflex amplitude at 1 Hz and at 0.1 Hz. The greater the 1 Hz/0.1 Hz ratio, the smaller the postactivation depression. Following robotic-assisted gait training, the 1 Hz/0.1 Hz ratio decreased from 0.79±0.26 at T0 to 0.56±0.18 at T1 and 0.58±0.13 at T2. Post hoc analysis showed a significant difference between T0 and T1 and between T0 and T2, stating an increase of postactivation depression. No significant differences were found between T1 and T2. This study provides the first demonstration that physical exercise can determine a partial normalization of postactivation depression in hemiparetic patients with spasticity following unilateral hemispheric stroke.

In stroke patients, it has been suggested that communication disorders could result from lexical and syntactic disorders in left hemisphere lesions and from pragmatics problems in right lesions. However, we have little information on patient behaviour in dyadic communication, especially in conversation. Here, we analyzed the various processes participating in communication difficulties at the rehabilitation phase (1-6 months) post-stroke, in order to define the main mechanisms of verbal and non-verbal communication (VC, NVC) disorders and their relationship with aphasic disorders. Sixty-three patients were recruited, who belonged to six groups, with left or right cortico-sub-cortical (L-CSC, R-CSC) or sub-cortical (L-SC, R-SC), frontal (Fro) or posterior fossa (PF) lesions. They were compared with an equivalent control group (gender, age, education level). We used the Lille Communication Test, which comprises three parts: participation to communication (greeting, attention, engagement), verbal communication (verbal comprehension, speech outflow, intelligibility, word production, syntax, verbal pragmatics and verbal feedback) and non-verbal communication (understanding gestures, affective expressivity, producing gestures, pragmatics and feedback). We also used the Functional Communication Profile and the Boston Diagnostic Aphasia Examination (BDAE). Decrease in participation was found in L-CSC, R-CSC and Fro patients. Verbal communication was essentially disrupted in L-SCS and L-SC groups, including by verbal pragmatic disorders, and to a lesser degree in frontal patients. Nonverbal communication was mainly affected in R-CSC patients, especially by pragmatic difficulties. L-CSC patients showed an increase in gesture production, compensating for aphasia. In conclusion, communication disorders were relatively complex and could not be summarised by syntactical and lexical difficulties in left stroke and pragmatic problems in right stroke. The former also showed severe
The study deals with an investigation of families who have to cope with the stroke of an older family member. The psychological reactions of the patient and the caregiver, related to the chronic disease and home care, are analyzed and a response hierarchy is delineated, as well. Moreover the burden, the patients and primary caregivers report, are given. Additionally, the most important dimensions of the "cognitive representation" the patient holds of his situation are investigated.

Stroke is considered one of the leading causes of death and acquired disability with a peak prevalence over the age of 80 years. Stroke may cause debilitating neurological deficiencies that frequently result in sensory deficits, motor impairment, muscular atrophy, cognitive deficits and psychosocial impairment. Oro-facial impairment may occur due to the frequent involvement of the cranial nerves' cortical representation areas, central nervous system pathways or motoneuron pools. The aim of this narrative, non-systematic review was to discuss the implications of stroke on oro-facial functions and oral health-related quality of life (OHRQoL). Stroke patients demonstrate an impaired masticatory performance, possibly due to reduced tongue forces and disturbed oral sensitivity. Furthermore, facial asymmetry is common, but mostly discrete and lip restraining forces are reduced. Bite force is not different between the ipsi- and contra-lesional side. In contrast, the contra-lesional handgrip strength and tongue-palate contact during swallowing are significantly impaired. OHRQoL is significantly reduced mainly because of the functional impairment. It can be concluded that impaired chewing efficiency, dysphagia, facial asymmetry, reduced lip force and OHRQoL are quantifiable symptoms of oro-facial impairment following a stroke. In the absence of functional rehabilitation, these symptoms seem not to improve. Furthermore, stroke affects the upper limb and the masseter muscle differently, both, at a functional and a morphological level. The rehabilitation of stroke survivors should, therefore, also seek to improve the strength and co-ordination of the oro-facial musculature. This would in turn help improve OHRQoL and the masticatory function, subsequently preventing weight loss and malnutrition. © 2017 John Wiley & Sons Ltd.

The proportion of diabetic patients who are hospitalised for stroke has been increasing in recent years, currently reaching almost a third of all cases of stroke. In addition, about half of patients with acute stroke present hyperglycaemia in the first hours of the stroke. Although hyperglycaemia in the acute phase of stroke is associated with a poor prognosis, its treatment is currently a topic of debate. There is no evidence that the adminstration of intravenous insulin to these patients offers benefits in terms of the evolution of the stroke. New studies in development, such as the SHINE study (Stroke Hyperglycemia Insulin Network Effort), may contribute to clarifying the role of intensive control of glycaemia during the acute phase of the stroke. Ultimately, patients who have presented with stroke should be screened for diabetes. Copyright © 2015 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI). All rights reserved.

Several studies investigated the prognostic role of copeptin in stroke. The aim of this study is to assess copeptin levels in serum, and investigate their associations with risk of recurrent stroke in a 1-year follow-up study in patients with ischemic stroke. In this post hoc analysis, serum levels of copeptin and NIH stroke scale (NIHSS) were measured at the time of admission in a cohort of 316 patients with ischemic stroke. The end point was stroke recurrence after 1-year follow-up. We used logistic regression model to assess the relationship between copeptin levels and risk recurrent stroke. Logistic regression analysis considering traditional risk factors showed a relationship between serum copeptin levels and moderate-to-high clinical severity when serum copeptin was used as a continuous variable (OR, 1.05; 95% CI, 1.03-1.09). In the follow-up, 54 patients (17.1%) had a stroke recurrence. The stroke recurrence events distribution across the copeptin quartiles ranged between 5.1% (first quartile) to 23.1% (fourth quartile). In multivariate models comparing the third (OR = 2.78; 95% CI 1.85-3.53) and fourth quartiles (OR = 4.00; 95% CI 2.86-6.50) against the first quartile of the copeptin, levels of copeptin were associated with stroke recurrence events. A higher serum copeptin level is a predictor of both severity at admission and stroke recurrence at 1-year in stroke patients.

Full Text Available Introduction. This study compared the balance by center of pressure (COP and its relationship with gait parameters and functional independence in left (LH and right (RH chronic stroke patients. Methods. In this cross-sectional study, twenty-one hemiparetic stroke patients were assessed for Functional Independence Measure (FIM, balance with a force platform, and gait in the Motion Analysis Laboratory. Results. The amplitudes of the COP in the anteroposterior and mediolateral directions were similar in both groups. The anteroposterior direction was greater than the mediolateral direction. Only the temporal parameters showed any statistically significant differences. The LH showed a significant correlation between stride length, step length, and gait velocity with COP velocity sway for the healthy and paretic lower limbs. In both groups, the area of COP was significantly correlated with stride length. Motor FIM was significantly correlated with the COP in the LH group. Conclusion. There was no difference in the performance of balance, gait, and functional independence between groups. The correlation of the COP sway area with stride length in both groups can serve as a guideline in the rehabilitation of these patients where training the static balance may reflect the improvement of the stride length.

Full Text Available Abstract Background Practicing arm and gait movements with robotic assistance after neurologic injury can help patients improve their movement ability, but patients sometimes reduce their effort during training in response to the assistance. Reduced effort has been hypothesized to diminish clinical outcomes of robotic training. To better understand patient slacking, we studied the role of visual distraction and auditory feedback in modulating patient effort during a common robot-assisted tracking task. Methods Fourteen participants with chronic left hemiparesis from stroke, five control participants with chronic right hemiparesis and fourteen non-impaired healthy control participants, tracked a visual target with their arms while receiving adaptive assistance from a robotic arm exoskeleton. We compared four practice conditions: the baseline tracking task alone; tracking while also performing a visual distracter task; tracking with the visual distracter and sound feedback; and tracking with sound feedback. For the distracter task, symbols were randomly displayed in the corners of the computer screen, and the participants were instructed to click a mouse button when a target symbol appeared. The sound feedback consisted of a repeating beep, with the frequency of repetition made to increase with increasing tracking error. Results Participants with stroke halved their effort and doubled their tracking error when performing the visual distracter task with their left hemiparetic arm. With sound feedback, however, these participants increased their effort and decreased their tracking error close to their baseline levels, while also performing the distracter task successfully. These effects were significantly smaller for the participants who used their non-paretic arm and for the participants without stroke. Conclusions Visual distraction decreased participants effort during a standard robot-assisted movement training task. This effect was greater for

Copeptin levels are increased in patients diagnosed with stroke and other vascular diseases. Copeptin elevation is associated with adverse outcome, predicts re-events in patients with transient ischemic attack and is used in ruling-out acute myocardial infarction. We evaluated whether copeptin can also be used as a diagnostic marker in the prehospital stroke setting. We prospectively examined patients with suspected stroke on the Stroke Emergency Mobile-an ambulance that is equipped with computed tomography and point-of-care laboratory. A blood sample was taken from patients immediately after arrival. We analyzed copeptin levels in patients with final hospital-based diagnosis of stroke or stroke mimics as well as in vascular or nonvascular patients. In addition, we examined the associations of symptom onset with copeptin levels and the prognostic value of copeptin in patients with stroke. Blood samples of 561 patients were analyzed. No significant differences were seen neither between cerebrovascular (n=383) and other neurological (stroke mimic; n=90) patients (P=0.15) nor between vascular (n=391) and nonvascular patients (n=170; P=0.57). We could not detect a relationship between copeptin levels and time from onset to blood draw. Three-month survival status was available in 159 patients with ischemic stroke. Copeptin levels in nonsurviving patients (n=8: median [interquartile range], 27.4 [20.2-54.7] pmol/L) were significantly higher than in surviving patients (n=151: median [interquartile range], 11.7 [5.2-30.9] pmol/L; P=0.024). In the prehospital setting, copeptin is neither appropriate to discriminate between stroke and stroke mimic patients nor between vascular and nonvascular patients. URL: http://www.clinicaltrials.gov.

Thiazides have been used for the control of blood pressure and primary prevention of ischemic stroke. No previous studies have assessed the influence of thiazides on functional prognosis after ischemic stroke. Demographics, prestroke conditions, poststroke National Institutes of Health Stroke Scale score, and clinical and laboratory parameters were prospectively registered in 216 Taiwanese patients. One hundred forty patients who completed follow-up 3 months after experiencing ischemic stroke were assessed with the modified Rankin scale as functional prognoses. Twenty-one patients used thiazide to control hypertension before experiencing ischemic stroke. No differences of stroke subtypes and comorbidities before stroke were observed between the 2 groups. The emergency department National Institutes of Health Stroke Scale was lesser among thiazide users (4 [2-7] versus 6 [4-16], P = .02). Among 140 patients who completed follow-up in 90 days, thiazide users had more favorable functional status (modified Rankin scale ≤2: 42.4% versus 26.9%, P = .02, odds ratio 3.34, 95%, confidence interval .130-.862). Hypertensive patients treated with thiazides long term had a lesser severity of stroke and better functional outcomes after ischemic stroke. Copyright © 2014 National Stroke Association.

Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk. In an observational cross-sectional study design, we surveyed 178 AF patients with a mean age of 70.6 years (SD 8.3) in stable anticoagulant treatment (65% treatment duration >12 months). Clinical stroke risk was scored through the CHA2DS2-VASc, and patients rated their perceived personal stroke risk on a 7-point Likert scale. There was no significant association between clinical stroke risk assessment and patients' stroke risk perception (rho = .025; P = .741). Approximately 60% of the high-risk patients had an unrealistic perception of their own stroke risk, and there was no significant increase in risk perception from those with a lower compared with a higher risk factor load (χ(2) = .010; P = .522). Considering possible negative implications in terms of lack of motivation for lifestyle behavior change and adequate adherence to the treatment and monitoring of vitamin K antagonist, the apparent underestimation of risk by large subgroups warrants attention and needs further investigation with regard to possible behavioral consequences.

Revascularisation treatment with thrombolysis must be initiated within 4.5 h following ischaemic stroke symptom onset. Despite its proven benefits, thrombolysis therapy is underused, with patient delay in presenting to hospital with symptoms identified as the leading barrier. This study aimed to examine help-seeking behaviour at stroke onset, in order to understand delays in accessing acute medical care for stroke symptoms. 149 consecutive patients hospitalised with ischaemic stroke were interviewed at 72 h poststroke with the Stroke Awareness Questionnaire and the Response to Symptoms Questionnaire. Sixty per cent of stroke cases presented to the ED within 3.5 h of stroke onset. Knowledge of stroke symptoms and risk factors was poor, with 40% unable to correctly define a stroke. Bystander recognition of symptoms (p=0.03) and bystander initiation of Emergency Medical Services was associated with ED presentation within 3.5 h (p=0.03). This study provides insights into patient response when a stroke occurs, with the presence and action of others highlighted as critical in fast response to stroke symptoms. Knowledge of stroke warning signs and risk factors was low among stroke survivors. Findings highlight the complexity of changing help-seeking behaviour during stroke onset, and provide directions for public education efforts to reduce prehospital delay.

The objective of this study was to investigate the incidence, and the factors influencing the development, of complex regional pain syndrome-I in the upper extremity in hemiplegic patients within the first 28 weeks following a stroke. We followed up 82 stroke patients. All patients were evaluated at weeks 2, 6, 14 and 28 after suffering a stroke. Outcomes were assessed using passive range of motion of shoulder, presence of subluxation, Ashworth score, Motricity index arm score, Brunnstrom stages and depression score. The incidence of complex regional pain syndrome-I was 48.8% in the first 28 weeks. Significant correlation was found between complex regional pain syndrome-I and the presence of subluxation, Ashworth score, Motricity index arm score, Brunnstrom stage and depression score (r=0.259, P=0.019; r=0.271, P=0.014; r=-0.393, Pspasticity of shoulder muscles and muscle strength. In order to prevent the development of complex regional pain syndrome-I, exercises directed at increasing the range of motion for the glenohumeral joint, strengthening shoulder muscles and reduction of spasticity will establish the integrity of the shoulder joint.

Neuropsychiatric symptoms can be interrelated to delirium. We aimed to investigate an association between pre-stroke neuropsychiatric symptoms and the risk of delirium in stroke patients. We included 606 patients (median age: 73, 53% female) with stroke or transient ischemic attack admitted within 48 hours from symptoms onset. We assessed delirium on a daily basis during the first 7 days of hospitalization. To make diagnosis of delirium we used DSM-5 criteria. We used Neuropsychiatric Inventory to assess neuropsychiatric symptoms occurring within 4 weeks prior to stroke. We diagnosed delirium in 28.2% of patients. On univariate analysis, higher score of pre-stroke depression (OR: 1.58, 95% CI: 1.04-2.40, P = 0.03), apathy (OR: 2.23, 95% CI: 1.44-3.45, P stroke severity, right hemisphere lesion, pre-stroke cognitive decline, pre-stroke disability and infections, higher apathy score (OR: 2.03, 95% CI: 1.17-3.50, P = 0.01), but no other neuropsychiatric symptoms, remained independent predictor of delirium. We conclude that pre-stroke apathy symptoms are associated with increased risk of delirium in stroke patients.

Comprehensive stroke unit care, incorporating acute care and rehabilitation, may promote early physical activity after stroke. However, previous information regarding physical activity specific to the acute phase of stroke and the comprehensive stroke unit setting is limited to one stroke unit. This study describes the physical activity undertaken by patients within 14 days after stroke admitted to a comprehensive stroke unit. This study was a prospective observational study. Behavioural mapping was used to determine the proportion of the day spent in different activities. Therapist reports were used to determine the amount of formal therapy received on the day of observation. The timing of commencement of activity out of bed was obtained from the medical records. On average, patients spent 45% (SD 25) of the day in some form of physical activity and received 58 (SD 34) minutes per day of physiotherapy and occupational therapy combined. Mean time to first mobilisation out of bed was 46 (SD 32) hours post-stroke. This study suggests that commencement of physical activity occurs earlier and physical activity is at a higher level early after stroke in this comprehensive stroke unit, when compared to studies of other acute stroke models of care.

Stroke is the second leading cause of death and the most important cause of adult disability worldwide and in Croatia. In the past, stroke was almost exclusively considered to be a disease of the elderly; however, today the age limit has considerably lowered towards younger age. The aim of this study was to determine age and gender impact on stroke patients in a Croatian urban area during one-year survey. The study included all acute stroke patients admitted to our Department in 2004. A compiled stroke questionnaire was fulfilled during hospitalization by medical personnel on the following items: stroke risk factors including lifestyle habits (smoking and alcohol), pre-stroke physical ability evaluation, stroke evolution data, laboratory and computed tomography findings, outcome data and post-stroke disability assessment. Appropriate statistical analysis of numerical and categorical data was performed at the level of p alcohol intake. Additionally, age analysis showed that heart conditions and smoking were more prevalent among older stroke patients. In conclusion, considerable differences were established between age and gender stroke patient groups, confirming the need of permanent national stroke registry and subsequent targeted action in secondary care, and prevention with education on risk factors, preferably personally tailored.

Previous studies examining social work interventions in stroke often lack information on content, methods and timing over different phases of care including acute hospital, rehabilitation and out-patient care. This limits our ability to evaluate the impact of social work in multidisciplinary stroke care. We aimed to quantify social-work-related support in stroke patients and their carers in terms of timing and content, depending on the different phases of stroke care. We prospectively collected and evaluated data derived from a specialized "Stroke-Service-Point" (SSP); a "drop in" center and non-medical stroke assistance service, staffed by social workers and available to all stroke patients, their carers and members of the public in the metropolitan region of Berlin, Germany. Enquiries from 257 consenting participants consulting the SSP between March 2010 and April 2012 related to out-patient and in-patient services, therapeutic services, medical questions, medical rehabilitation, self-help groups and questions around obtaining benefits. Frequency of enquiries for different topics depended on whether patients were located in an in-patient or out-patient setting. The majority of contacts involved information provision. While the proportion of male and female patients with stroke was similar, about two thirds of the carers contacting the SSP were female. The social-work-related services provided by a specialized center in a German metropolitan area were diverse in terms of topic and timing depending on the phase of stroke care. Targeting the timing of interventions might be important to increase the impact of social work on patient's outcome.

Stroke risk prediction scores have been designed to stratify risk of recurrent cerebrovascular events in transient ischemic attack (TIA) and minor ischemic stroke (MIS) patients. Consecutive TIA or MIS patients referred to Ghaem Hospital, Mashhad were enrolled in a prospective cohort study during 2010-2011. Only TIA or MIS patients presenting within 24 h from the onset of symptoms were recruited. MIS was considered as ischemic stroke with NIHSS ABCD(2) scoring system for recurrent stroke or TIA was quantified by the area under the cure (AUC) using the c statistics. Three hundred ninety-three TIA patients (238 males, 155 females) and 118 MIS patients (77 males, 41 females) were enrolled in the study. One hundred seventeen strokes (23.2%), 99 TIA (19.6%), and 11 vascular death (2.2%) occurred within 3 months postevent in the whole of our 511 patients with minor ischemic events. The ABCD(2) score had a weak predictive value for 3 months and 3 days recurrent stroke in our TIA patients (AUC = 0.599, AUC = 0.591), but a high predictive value for 3 months and 3 days recurrent stroke in our MIS patients (AUC = 0.727, AUC = 0.728), respectively. The ABCD(2) score is highly predictive of short-term recurrent stroke in MIS patients but not TIA cases, despite its creation for TIA cohorts.

The stroke mortality rate in the Polish population is significantly higher than the average stroke mortality in Western Europe. It may prove a poor "initial" health condition of the Polish population which is afflicted with many life-threatening diseases which are at the same time the major risk factors for both: first ever and recurrent stroke. The aim of our study was to evaluate what is an attitude of Polish people with first-ever or recurrent stroke to keeping under control the most important risk factors for ischemic stroke. 1282 consecutive patients with ischemic stroke were examined and categorized as individuals with first ever (group I - 980 patients) and recurrent stroke (group II - 302 patients). The data on the patients' previous history of stroke and vascular modifiable risk factors diagnosed before the onset of stroke: arterial hypertension (AH), type 2 diabetes mellitus (DM), ischemic heart disease (IHD), atrial fibrillation (AF), cigarette smoking and alcohol consumption were determined. The treatment with antiplatelet agents or oral anticoagulants was also taken into account. More than one-third ofpatients, irrespective of group admitted that they had treated AH unsystematically or not treated at all. Based on initial blood pressure, it may be suspected, that also individuals declaring systematic AH treatment, did not do it effectively. It also concerned the type 2 DM - glycemic control remained unsatisfactory within the period preceding first-ever and recurrent stroke. After first stroke, the patients haven't changed their habits considering tobacco smoking and alcohol consumption. The anticoagulants were used relatively seldom in relation to recommendations in both group of patients. The main risk factors for ischemic stroke are poorly controlled by Polish patients before first ever stroke. After the first cerebrovascular event they usually don't change their habits, which lead to recurrent stroke. In Poland the educational strategies regarding

Hyperthermia is a frequent complication in patients with acute ischemic stroke. On the other hand, therapeutically induced hypothermia has shown promising potential in animal models of focal cerebral ischemia. This Guideline Document presents the European Stroke Organisation guidelines for the management of temperature in patients with acute ischemic stroke. A multidisciplinary group identified related questions and developed its recommendations based on evidence from randomized controlled trials elaborating the Grading of Recommendations Assessment, Development, and Evaluation approach. This Guideline Document was reviewed within the European Stroke Organisation and externally and was approved by the European Stroke Organisation Guidelines Committee and the European Stroke Organisation Executive Committee. We found low-quality evidence, and therefore, we cannot make any recommendation for treating hyperthermia as a means to improve functional outcome and/or survival in patients with acute ischemic stroke and hyperthermia; moderate evidence to suggest against routine prevention of hyperthermia with antipyretics as a means to improve functional outcome and/or survival in patients with acute ischemic stroke and normothermia; very low-quality evidence to suggest against routine induction of hypothermia as a means to improve functional outcome and/or survival in patients with acute ischemic stroke. The currently available data about the management of temperature in patients with acute ischemic stroke are limited, and the strengths of the recommendations are therefore weak. We call for new randomized controlled trials as well as recruitment of eligible patients to ongoing randomized controlled trials to allow for better-informed recommendations in the future. © 2015 World Stroke Organization.

To carry out a proof of concept study for integrating robot therapy with physiotherapy in the treatment of stroke patients. A simple and 'gentle' paradigm of robot-patient interaction was designed in order to foster the re-emergence of smooth, active control patterns in coordinated shoulder/elbow reaching movements. A haptic robot was programmed according to a strategy of minimal, progressively reduced assistance, with a double representation of targets: (i) visual (circles on a screen) and (ii) haptic (robot-generated force fields). The protocol included trials with and without vision, in order to emphasize the role of proprioceptive feedback. The training paradigm included 10 sessions and more than 5000 movements. Ten chronic, hemiparetic subjects; four controls provided reference values for the performance measurements. Four performance indicators (derived from the analysis of the reaching trajectories); clinical/functional measures (Fugl-Meyer and Ashworth scales). After robot therapy reaching movements became faster and smoother. The performance in the no-vision trials was at least as good as in the vision trials. The Fugl-Meyer arm scores also increased significantly and remained approximately constant at follow-up; the Ashworth scores did not change. In spite of its simplicity, a limited number of ;gentle' robot therapy sessions appear to be beneficial, even for severely impaired patients, although no firm conclusion can be drawn at this point. However, the study provides support material for the careful design of controlled clinical trials and for a better integration with physiotherapy.

Guided quality improvement (QI) programs present an effective means to streamline stroke code to computed tomography (CT) times in a comprehensive stroke center. Applying QI methods and a multidisciplinary team approach may decrease the stroke code to CT time in non-prenotified emergency department (ED) patients presenting with symptoms of stroke. The aim of this project was to decrease this time for non-prenotified stroke code patients from a baseline mean of 20 minutes to one less than 15 minutes during an 18-week period by applying QI methods in the context of a structured QI program. By reducing this time, it was expected that the door-to-CT time guideline of 25 minutes could be met more consistently. Through the structured QI program, we gained an understanding of the process that enabled us to effectively identify key drivers of performance to guide project interventions. As a result of these interventions, the stroke code to CT time for non-prenotified stroke code patients decreased to a mean of less than 14 minutes. This article reports these methods and results so that others can similarly improve the time it takes to perform nonenhanced CT studies in non-prenotified stroke code patients in the ED. ©RSNA, 2017.

Full Text Available This report describes the modification of hemiplegic shoulder pain and walking velocity through injections of Xeomin®, a new botulinum neurotoxin type A formulation, in a 67-year-old woman with chronic residual left hemiparesis and hemiparetic gait attributable to stroke. Clinical evaluation included upper and lower limb spasticity, upper and lower limb pain, trunk control, upper and lower limb motricity index, visual gait analysis, and gait velocity. Assessments were performed before, 1 week after, and 1 month after treatment. Improvement was observed in all clinical parameters assessed. Amelioration of spasticity of the upper and lower limbs and shoulder pain was observed after 1 month. Trunk postural attitude and paraxial muscle recruitment recovered. No adverse events were observed and the patient shows significant improvement of functional impairment derived from chronic spasticity after treatment with Xeomin®. We also provide a simple and useful protocol for clinical evaluation of the treatment.

The influence of pneumonia in acute stroke stage on the clinical presentation and long-term outcomes of patients with acute ischemic stroke is still controversial. We investigate the influence of pneumonia in acute stroke stage on the 3-year outcomes of patients with acute first-ever ischemic stroke. Nine-hundred and thirty-four patients with acute first-ever ischemic stroke were enrolled and had been followed for 3years. Patients were divided into two groups according to whether pneumonia occurred during acute stroke stage or not. Clinical presentations, risk factors for stroke, laboratory data, co-morbidities, and outcomes were recorded. The result showed that a total of 100 patients (10.7%) had pneumonia in acute stroke stage. The prevalence of older age, atrial fibrillation was significantly higher in patients with pneumonia in acute stroke stage. Total anterior circulation syndrome and posterior circulation syndrome occurred more frequently among patients with pneumonia in acute stroke stage (Ppneumonia in acute stroke stage is a significant predictor of 3-year mortality (hazard ratio=6.39, 95% confidence interval=4.03-10.11, Ppneumonia during the acute stroke stage is associated with increased risk of 3-year mortality.

Improvements in acute care of stroke patients have decreased mortality, but survivors are still at increased risk of future vascular events and mitigation of this risk requires thorough assessment of the underlying factors leading to the stroke. The brain and eye share a common embryological origin and numerous similarities exist between the small vessels of the retina and brain. Recent population-based studies have demonstrated a close link between retinal vascular changes and stroke, suggesting that retinal photography could have utility in assessing underlying stroke risk factors and prognosis after stroke. Modern imaging equipment can facilitate precise measurement and monitoring of vascular features. However, use of this equipment is a challenge in the stroke ward setting as patients are frequently unable to maintain the required seated position, and pupil dilatation is often not feasible as it could potentially obscure important neurological signs of stroke progression. This small study investigated the utility of a novel handheld, nonmydriatic retinal camera in the stroke ward and explored associations between retinal vascular features and stroke risk factors. This camera circumvented the practical limitations of conducting retinal photography in the stroke ward setting. A positive correlation was found between carotid disease and both mean width of arterioles (r = .40, P = .00571) and venules (r = .30, P = .0381). The results provide further evidence that retinal vascular features are clinically informative about underlying stroke risk factors and demonstrate the utility of handheld retinal photography in the stroke ward.

Full Text Available This study aimed to detect the difference in resting cerebral activities between ischemic stroke patients and healthy participants, define the abnormal site, and provide new evidence for pathological mechanisms, clinical diagnosis, prognosis prediction and efficacy evaluation of ischemic stroke. At present, the majority of functional magnetic resonance imaging studies focus on the motor dysfunction and the acute stage of ischemic stroke. This study recruited 15 right-handed ischemic stroke patients at subacute stage (15 days to 11.5 weeks and 15 age-matched healthy participants. A resting-state functional magnetic resonance imaging scan was performed on each subject to detect cerebral activity. Regional homogeneity analysis was used to investigate the difference in cerebral activities between ischemic stroke patients and healthy participants. The results showed that the ischemic stroke patients had lower regional homogeneity in anterior cingulate and left cerebrum and higher regional homogeneity in cerebellum, left precuneus and left frontal lobe, compared with healthy participants. The experimental findings demonstrate that the areas in which regional homogeneity was different between ischemic stroke patients and healthy participants are in the cerebellum, left precuneus, left triangle inferior frontal gyrus, left inferior temporal gyrus and anterior cingulate. These locations, related to the motor, sensory and emotion areas, are likely potential targets for the neural regeneration of subacute ischemic stroke patients.

Complementary and alternative medicine (CAM) is commonly used by persons with stroke throughout the world, particularly in Asia. The objectives of this study were to determine the frequency of CAM use and the factors that predict the use of CAM in stroke patients. This study was carried out in the stroke units of Christian Medical College, Ludhiana, and Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram, India, from June 2010 to December 2010. Participants were interviewed using a structured questionnaire (≥ 6 months post stroke). Outcomes were assessed using a modified Rankin Scale (mRS). Three hundred fourteen stroke patients were interviewed; mean age was 57.4 ± 12.9 years, and 230 (73.2%) patients were men. Of 314 patients, 114 (36.3%) had used the following CAM treatments: ayurvedic massage, 67 (59.3%); intravenous fluids, 22 (19.5%); herbal medicines, 17 (15%); homeopathy, 15 (13.3%); witchcraft, 3 (2.7%); acupuncture, 3 (2.7%); opium intake, 10 (8.8%); and other nonconventional treatments, 10 (8.8%). Patients with severe stroke (P 2;P < .0001) often used CAM treatments. More than one-third of the patients in this study opted for CAM. Presence of limb weakness, dysphagia, dyslipidemia, hypertension, hemorrhagic stroke, severe stroke, and poor outcome predicted the use of CAM.

Full Text Available CONTEXT: Stroke is a frequent cause of dysphagia. OBJECTIVE: To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS: Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and radiologic diagnosis of stroke. The occurrence of death was determined 3 months after the stroke. RESULTS: It was observed that 63% of the patients had swallowing dysfunction. The variables gender and specific location of the lesion were not associated with the presence or absence of swallowing dysfunction. The patients with swallowing dysfunction had more frequently a previous stroke, had a stroke in the left hemisphere, motor and/or sensitivity alterations, difficulty in oral comprehension, alteration of oral expression, alteration of the level of consciousness, complications such as fever and pneumonia, high indexes on the Rankin scale, and low indexes on the Barthel scale. These patients had a higher mortality rate. CONCLUSIONS: Swallowing evaluation should be done in all patients with stroke, since swallowing dysfunction is associated with complications and an increased risk of death.
Full Text Available Objective: Case report Impact of Botulinum Toxin injection on function of affected upper extremity in a patient after 16 years since stroke (CVA. Botulinum toxin injection is one the treatments in spasticity reduction and consequently in recovery of upper limb function in stroke patients. The purpose of this case study is to report the effect of Botulinum toxin injection on upper extremity function after 16 years of stroke. Materials & Methods: The patient was a 63-year-old man who has had a cerebrovascular accident that happened in the left hemisphere about 16 years ago, and as a result, a paresis in dominant hand and arm. Although the patient was able to perform simple movements but he was complaining about the slowness and stiffness in the movements. To treat spasticity the Botulinum toxin type A was used. Injection into selected muscles of hemiparetic upper limb was done by a specialist physician and was between 50-150IU based on specific volume of each muscle. After injection, the patient was monitored for 3 months and at the end of each month, the assessments were reevaluated. During this period, although research team suggested the patient to continue the rehabilitation but for personal reasons he didn’t participate in any treatment and didn`t receive any other antispasmodic medications. Results: An increase in range of motion was seen in all joints but this improvement was not significant. The greatest improvement in passive and active range of motion was seen in Metacarpophalengeal joints. At the end of each month, compared to the first month the recovery of function in upper extremity was significant. Maximum recovery of upper extremity function was related to the hand section of fugl-meyer assessment. At the end of the first month, spasticity significantly decreased so that the patient was able to extend all his joints more easily than before injection. Although spasticity never reached zero. Conclusion: Botulinum toxin injection

Background Data on the epidemiology and risk factors of altered gastrointestinal motility (AGIM) is virtually lacking for patients suffering from non-traumatic neurologic diseases and stroke. This study investigated whether patterns of AGIM differ between patients with stroke and other severe acute brain diseases. Methods Clinical records of stroke and non-stroke patients treated at a neurological intensive care unit (ICU) were reviewed at day 1-5 and at day 10 after admission. The data was analyzed for the course of enteral/parenteral nutrition and for and for signs and symptoms of gastrointestinal dysfunction. The study included data of 76 patients, 57 with stroke (stroke group, SG) and 19 with other neurological diseases (non-stroke group, NSG). Results Basic demographic as well as clinical baseline characteristics and alimentation regime were similar in both groups. At least one sign of AGIM was seen in 33/57 (58%) SG and in 15/19 (79%) NSG patients (P = 0.099). Regurgitation was significantly more frequent among patients from the NSG (P < 0.05). Subjects from the NSG also spent a higher proportion of time with at least one symptom of AGIM present (P < 0.05). Conclusions For the first time, this study investigated the prevalence of AGIM in patients suffering from severe stroke. The prevalence of disturbed gastrointestinal function was found to be high in stroke patients, but was lower than in a group of non-stroke patients with similar general disease severity and baseline characteristics.

Full Text Available Vascular cognitive impairment (VCI is characterized by cognitive compromise predominantly of executive dysfunction. OBJECTIVES: To assess cognitive functions in VCI, focusing on executive functions, to observe functional losses in relation to activities of daily living (ADLs and to detect early symptoms prior to the onset of dementia. METHODS: We evaluated healthy subjects matched for gender, education and age to patients with diagnosis of subcortical vascular disease who had a stroke classified into three groups: 1 vascular lesions and no impairment; 2 vascular cognitive impairment with no dementia (VCIND; 3 vascular dementia (VaD. RESULTS AND DISCUSSION: The performance on neuropsychological tests differed among groups, worsening with increased impairment level. The probable VaD group demonstrated impaired performance in memory, processing speed and verbal production, while the VCIND group showed attention deficits. CONCLUSION: Impairment in executive functions and difficulties in ADLs allow us to differentiate levels of impairment in groups of subcortical vascular disease.

Elevated lipoprotein (a) concentration is associated with carotid atherosclerosis in middle-aged and older patients with ischemic stroke. This association has not been explored in young patients with stroke. A retrospective analysis of data from patients aged 16 to 54 years consecutively treated for acute ischemic stroke in a tertiary stroke unit during 4.5 years was performed. We graded carotid atherosclerosis using carotid duplex as: no atherosclerosis (A); plaque without stenosis (B); or stenosis≥50% (C). One hundred ninety-six patients were included (male/female: 119/77; mean age±SD: 44.3±8.6 years): 115 in Group A; 67 in Group B; and 14 in Group C. Multivariate analysis using polynomial logistic regression showed a graded association of lipoprotein (a) plasma concentration with carotid atherosclerosis (Patherosclerosis in young adults with ischemic stroke. This association was strong, graded, and independent of traditional risk factors including cholesterol.

Full Text Available Introduction. Strokes and stroke-mimics have been extensively studied in the emergency department setting. Although in-hospital strokes are less studied in comparison to strokes in the emergency department, they are a source of significant direct and indirect costs. Differentiating in-hospital strokes from stroke-mimics is important. Thus, our study aimed to identify variables that can differentiate in-hospital strokes from stroke-mimics. Methods. We present here a retrospective analysis of 93 patients over a one-year period (2009 to 2010, who were evaluated for a concern of in-hospital strokes. Results. About two-thirds (57 of these patients were determined to have a stroke, and the remaining (36 were stroke-mimics. Patients with in-hospital strokes were more likely to be obese (p=0.03, have been admitted to the cardiology service (p=0.01, have atrial fibrillation (p=0.03, have a weak hand or hemiparesis (p=0.03, and have a prior history of stroke (p=0.05, whereas, when the consults were called for “altered mental status” but no other deficits (p<0.0001, it is likely a stroke-mimic. Conclusion. This study demonstrates that in-hospital strokes are a common occurrence, and knowing the variables can aid in their timely diagnosis and treatment.

Full Text Available The presence of chronic kidney disease (CKD is an indicator of a worse long-term prognosis in patients with ischemic stroke (IS. Unfortunately, not much is known about renal function in the population of post-IS subjects. The aim of our study was to assess the prevalence of renal damage and impaired renal function (IRF in the population of post-IS subjects.This prospective analysis concerned 352 consecutive post-IS survivors hospitalized in Pomeranian stroke centers (Poland in 2009.

Initial stroke severity is one of the strongest predictors of eventual stroke outcome. However, predictors of initial stroke severity have not been well-described within a population. We hypothesized that poorer patients would have a higher initial stroke severity on presentation to medical attention. We identified all cases of hospital-ascertained ischemic stroke occurring in 2005 within a biracial population of 1.3 million. "Community" socioecomic status was determined for each patient based on the percentage below poverty in the census tract in which the patient resided. Linear regression was used to model the effect of socioeconomic status on stroke severity. Models were adjusted for race, gender, age, prestroke disability, and history of medical comorbidities. There were 1895 ischemic stroke events detected in 2005 included in this analysis; 22% were black, 52% were female, and the mean age was 71 years (range, 19-104). The median National Institutes of Health Stroke Scale was 3 (range, 0-40). The poorest community socioeconomic status was associated with a significantly increased initial National Institutes of Health Stroke Scale by 1.5 points (95% confidence interval, 0.5-2.6; P<0.001) compared with the richest category in the univariate analysis, which increased to 2.2 points after adjustment for demographics and comorbidities. We found that increasing community poverty was associated with worse stroke severity at presentation, independent of other known factors associated with stroke outcomes. Socioeconomic status may impact stroke severity via medication compliance, access to care, and cultural factors, or may be a proxy measure for undiagnosed disease states.

This study describes the development of a Rasch-built scale measuring activity limitations in stroke patients, named ACTIVLIM-Stroke. This new Rasch-built measure was constructed based on stroke patients' perceptions of difficulty in performing daily activities. Patients were recruited from inpatient and outpatient rehabilitation departments in Belgium and Benin. A 73-item questionnaire was completed by 204 participants. A random subsample of 83 subjects was given the questionnaire a second time. Data were analyzed using RUMM2030 software. After successive Rasch analyses, the ACTIVLIM-Stroke questionnaire, a unidimensional and linear 20-item measure of activity limitations, was constructed. All 20 items fulfilled Rasch requirements (overall and individual item fit, category discrimination, invariance, local response independence, and nonredundancy in item difficulty). This simple patient-based scale encompasses a large range of activities related to self-care, transfer, mobility, manual ability, and balance. The ACTIVLIM-Stroke questionnaire exhibited high internal validity, excellent internal consistency, and good crosscultural validity. The test-retest reliability of item difficulty hierarchy (intraclass correlation coefficient=0.99) and patient location (intraclass correlation coefficient=0.92) were both excellent. Furthermore, it showed good external construct validity using correlations with the Functional Independence Measure motor and the Barthel Index and a higher discriminating capacity than either of these widely used indices. The ACTIVLIM-Stroke questionnaire has good psychometric qualities and provides accurate measures of activity limitations in patients with stroke. It is recommended for evaluating clinical and research interventions in patients with stroke, because it provides a higher discrimination and might be more sensitive to change.

Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to 72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p dysphagia was independently correlated with an increase in mortality (OR 3.2; 95% CI 2.4-4.2; p Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability. © 2016 S.

Readmissions after stroke are costly. Risk assessment using information available upon admission could identify high-risk patients for potential interventions to reduce readmissions. Baseline stroke severity has been suspected to be a factor in readmission; however, the exact nature of the impact has not been adequately understood. Hospitalized adult patients with first-ever ischemic stroke were identified from a nationwide administrative database. Stroke severity was assessed using a validated claims-based stroke severity index. Cox proportional hazards models were used to investigate the relationship between stroke severity and first readmission within one year. Of the 10,877 patients, 4295 (39.5%) were readmitted in one year. The cumulative risk of readmission was 34.1%, 44.7%, and 62.9% in patients with mild, moderate, and severe stroke, respectively. Patients with greater stroke severity had a significantly higher adjusted risk of first readmission for infection, metabolic disorders, neurological sequelae, and pulmonary diseases, whereas those with lesser stroke severity were prone to first readmission due to accidents. Stroke severity did not affect the risk of first readmission for recurrent stroke/transient ischemic attack, other cardiovascular events, malignancy, ulcers/upper gastrointestinal bleeding, kidney diseases, and others. Stroke severity in patients with first-ever ischemic stroke not only predicts readmission but also relates to the cause of readmission. Our results might provide important information for tailoring discharge planning to prevent readmissions. Copyright © 2016 Elsevier B.V. All rights reserved.

Full Text Available Background: Gait disorder is a common motor complication after stroke. Studies have revealed that conventional physiotherapy cannot manage this disorder efficiently; therefore, more studies regarding efficient treatment protocols are crucial. The purpose of this study was to investigate the effect of compelled weight-bearing approach on muscle activation patterns during walking in individuals with stroke. Methods: 24 hemiparetic patients participated in this study. Patients were randomly divided into 2 groups: experimental and control. The experimental group received increased weight bearing on the paretic leg via a shoe lift in addition to physical therapy for 6 weeks. The control group received only physical therapy. Laboratory assessments included weight-bearing symmetry ratio and electromyographic parameters recored from the medial gastrocnemius, tibialis anterior, rectus femoris and biceps femoris. The amplitude and duration of electromyographic activity for each subject was then calculated during the stance and swing phases of their gait cycle. All measurements were compared within and between groups after the termination of treatment. Results: After treatment, weight-bearing symmetry ratio improved significantly in the experimental group. Additionally, the electromyographic activity of paretic medial gastrocnemius increased significantly during the stance phase while activity duration of paretic rectus femoris decreased significantly in swing phase. In the control group, the weight-bearing symmetry ratio didn’t change significantly. Only activity duration of non-paretic rectus femoris decreased significantly in swing phase. Conclusion: The results show that compelled weight bearing on the paretic side improve amplitude and the timing for activity of some muscles in the lower limbs during walking.
Full Text Available ABSTRACT One in six patients admitted for stroke was previously demented. These patients have less access to appropriate stroke care, although little is known about their optimal management. Objective To determine how pre-stroke cognitive impairment can be detected, its mechanism, and influence on outcome and management. Methods Literature search. Results (i A systematic approach with the Informant Questionnaire of Cognitive Decline in the Elderly is recommended; (ii Pre-stroke cognitive impairment may be due to brain lesions of vascular, degenerative, or mixed origin; (iii Patients with pre-stroke dementia, have worse outcomes, more seizures, delirium, and depression, and higher mortality rates; they often need to be institutionalised after their stroke; (iv Although the safety profile of treatment is not as good as that of cognitively normal patients, the risk:benefit ratio is in favour of treating these patients like others. Conclusion Patients with cognitive impairment who develop a stroke have worse outcomes, but should be treated like others.

Stroke patients can experience a variety of pain. Many stroke patients have co-morbidities such as osteoporosis, arthritis or diabetes causing diabetic neuropathy. As well as pain from other long term conditions, stroke patients can experience central post-stroke pain, headaches, and musculoskeletal issues such as hypertonia, contractures, spasticity, and subluxations. These stroke patients can also have communication difficulties in the form of expressive dysphasia and/or global aphasia. Communication difficulties can result in these patients not expressing their pain and therefore not having it assessed, leading to inadequate pain relief that could impact their rehabilitation and recovery. By implementing an observational measurement of pain such as the Abbey pain scale, patients with communication difficulties can have their pain assessed and recorded. Initially 30% of patients on the acute stroke ward did not have their pain assessed and adequately recorded and 15% of patients had inadequate pain relief. The patient was assessed if they were in pain and therefore not receiving adequate pain relief by measuring their pain on the Abbey pain scale. After introducing the Abbey pain scale and creating a nurse advocate, an improvement was shown such that only 5% of patients did not have their pain recorded and all had adequate pain relief.

The use of physiotherapy, occupational therapy, and speech therapy for patients with stroke was investigated, and the three treatments were compared. Out of 135 patients with stroke surviving at two weeks, 107 received physiotherapy, but only 35 received occupational therapy and 19 speech therapy. Those who received most physiotherapy were the most severely disabled and had the worst prognosis, and, although almost no recovery occurred after six months, 30 patients continued with treatment be...

In addition to changes in spatio-temporal and kinematic parameters, patients with stroke exhibit fear of falling as well as fatigability during gait. These changes could compromise interpretation of data from gait analysis. The aim of this study was to determine if the gait of hemiplegic patients changes significantly over successive gait trials. Forty two stroke patients and twenty healthy subjects performed 9 gait trials during a gait analysis session. The mean and variability of spatio-tem...

Background Elastic tape has been widely used in clinical practice in order to improve upper limb (UL) sensibility. However, there is little evidence that supports this type of intervention in stroke patients. Objective To verify the effect of elastic tape, applied to the paretic shoulder, on joint position sense (JPS) during abduction and flexion in subjects with chronic hemiparesis compared to sham tape (non-elastic tape). Furthermore, to verify if this potential effect is correlated to shoulder subluxation measurements and sensorimotor impairment. Methods A crossover and sham-controlled study was conducted with post-stroke patients who were randomly allocated into two groups: 1) those who received Sham Tape (ST) first and after one month they received Elastic Tape (ET); 2) those who received Elastic Tape (ET) first and after one month they received Sham Tape (ST). The JPS was evaluated using a dynamometer. The absolute error for shoulder abduction and flexion at 30° and 60° was calculated. Sensorimotor impairment was determined by Fugl-Meyer, and shoulder subluxation was measured using a caliper. Results Thirteen hemiparetic subjects (average time since stroke 75.23 months) participated in the study. At baseline (before interventions), the groups were not different for abduction at 30° (p = 0.805; p = 0.951), and 60° (p = 0.509; p = 0.799), or flexion at 30° (p = 0.872; p = 0.897) and 60° (p = 0.853; p = 0.970). For the ET group, differences between pre and post-elastic tape for abduction at 30° (ptape for abduction at 30° (ptape improved shoulder JPS of subjects with chronic hemiparesis regardless of the level of UL sensorimotor impairment. However, this improvement was influenced by the subluxation degree at abduction. PMID:28099472

Full Text Available Abstract Background Stroke is a major cause of death and long-term disability in Western societies and constitutes a major claim on health care budgets. Organising stroke care in a stroke service has recently been demonstrated to result in better health effects for patients. This paper discusses patient costs after stroke and compares costs between regular and stroke service care. Methods Costs were calculated within the framework of the evaluation of three experiments with stroke services in the Netherlands. Cost calculations are base on medical consumption data and actual costs. Results 598 patients were consecutively admitted to hospital after stroke. The average total costs of care per patient for the 6 month follow-up are estimated at €16,000. Costs are dominated by institutional and accommodation costs. Patients who die after stroke incur less costs. For patients that survive the acute phase, the most important determinants of costs are disability status and having a partner – as they influence patients' stroke careers. These determinants also interact. The most efficient stroke service experiment was most successful in co-ordinating patient flow from hospital to (nursing home, through capacity planning and efficient discharge procedures. In this region the costs of stroke service care are the same as for regular stroke care. The other experiments suffered from waiting lists for nursing homes and home care, leading to "blocked beds" in hospitals and nursing homes and higher costs of care. Costs of co-ordination are estimated at about 3% of total costs of care. Conclusion This paper demonstrates that by organising care for stroke patients in a stroke service, better health effects can be achieved with the same budget. In addition, it provides insight in need, predisposing and enabling factors that determine costs of care after stroke.

The cardiovascular system is regulated by the autonomic nervous system, under cortical modulation. Stroke can induce cardiac autonomic imbalance, therefore, causing secondary cardiovascular complications. Heart rate variability (HRV) analysis is a simple method to appraise the autonomic nervous function. The purpose of this study was to investigate the cardiac autonomic activity in patients that suffered an ischemic stroke in middle cerebral artery (MCA) territory. Using Biopac Acquisition System, we monitored ECG in rest condition and during Ewing's tests. From these measurements, HRV parameters (using time and frequency domain analysis) were determined in 20 right MCA and 20 left MCA ischemic stroke patients, in the first 6 months after the acute event. Data were compared with 20 age- and sex-matched healthy controls. All the patients were right handed. In ischemic stroke patients, HRV parameters were significantly modified compared to controls (p < 0.05) and we found asymmetric responses to different stimulation autonomic tests between right and left hemisphere. Parameters illustrating the parasympathetic predominance in time domain (RMSSD) and frequency domain (HF) analysis were higher in left hemisphere stroke compared to right hemisphere stroke patients (p < 0.01) in resting state. From Ewing's battery test, patients with left hemisphere ischemic stroke showed predominance of parasympathetic activity to deep breathing (p < 0.01), while HRV parameters in right hemisphere ischemic stroke patients described a reduced cardiac parasympathetic innervation (p < 0.01). Cardiac autonomic imbalance occurs more often after right hemisphere ischemic stroke. HRV study may highlight cardiac dysfunctions that increase the risk of cardiovascular complications and portends a poor long-term outcome.

To investigate the diagnostic yield of prehospital ECG monitoring provided by emergency medical services in the case of suspected stroke. Consecutive patients with acute stroke admitted to our tertiary stroke center via emergency medical services and with available prehospital ECG were prospectively included during a 12-month study period. We assessed prehospital ECG recordings and compared the results to regular 12-lead ECG on admission and after continuous ECG monitoring at the stroke unit. Overall, 259 patients with prehospital ECG recording were included in the study (90.3% ischemic stroke, 9.7% intracerebral hemorrhage). Atrial fibrillation (AF) was detected in 25.1% of patients, second-degree or greater atrioventricular block in 5.4%, significant ST-segment elevation in 5.0%, and ventricular ectopy in 9.7%. In 18 patients, a diagnosis of new-onset AF with direct clinical consequences for the evaluation and secondary prevention of stroke was established by the prehospital recordings. In 2 patients, the AF episodes were limited to the prehospital period and were not detected by ECG on admission or during subsequent monitoring at the stroke unit. Of 126 patients (48.6%) with relevant abnormalities in the prehospital ECG, 16.7% received medical antiarrhythmic therapy during transport to the hospital, and 6.4% were transferred to a cardiology unit within the first 24 hours in the hospital. In a selected cohort of patients with stroke, the in-field recordings of the ECG detected a relevant rate of cardiac arrhythmia. The results can add to the in-hospital evaluation and should be considered in prehospital care of acute stroke. © 2017 American Academy of Neurology.

There has been an increasing interest in the arts in health care, with a suggestion that the arts and aesthetics can augment patient outcomes in stroke and other illnesses. Designing such programmes requires better knowledge of the artistic, aesthetic, and cultural pursuits of people affected by stroke. The aim of this study was to obtain the insights of this group about the profile of art and aesthetic activities in their lives and the influence of stroke on these aspects. Patients attending a stroke service were administered questions adapted from the Irish Arts Council's 2006 questionnaire on participation in aesthetics and cultural pursuits. Information was also collected on stroke type and present functional and cognitive status. Thirty-eight patients were interviewed. Of these, 20 were inpatients in hospital at the time of the interview and 18 were interviewed in an outpatient setting. Popular activities included mainstream cinema, listening to music, dancing, attending plays or musicals, and being outdoors. Many patients ceased these activities after their stroke, mostly because of health issues and inaccessibility. Most of the patients valued the importance of the arts in the health-care setting. This study gives a perspective for the first time on the aesthetic and cultural pursuits of stroke patients before their stroke. It portrays a wide variety of cultural and leisure activities and the cessation of these poststroke. It revealed the restrictions patients felt on gaining access to leisure pursuits both while in hospital and following discharge. Copyright © 2013 National Stroke Association.

Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months. Review of a database of a population study on the incidence, 30-day case fatality rate, and prognosis of stroke performed in a northern Chilean city between 2000 and 2002. Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients. Partial anterior circulation infarction was the most common stroke location in 61%. Twenty percent of patients with a first episode of ischemic stroke have aphasia.

Full Text Available Stroke care presents unique challenges for clinicians, as most strokes occur in the context of other medical diagnoses. An assessment of capacity for implementing “best practice” stroke care found clinicians reporting a strong need for training specific to patient/system complexity and multimorbidity. With mounting patient complexity, there is pressure to implement new models of healthcare delivery for both quality and financial sustainability. Policy makers and administrators are turning to clinical practice guidelines to support decision-making and resource allocation. Stroke rehabilitation programs across Canada are being transformed to better align with the Canadian Stroke Strategy’s Stroke Best Practice Recommendations. The recommendations provide a framework to facilitate the adoption of evidence-based best practices in stroke across the continuum of care. However, given the increasing and emerging complexity of patients with stroke in terms of multimorbidity, the evidence supporting clinical practice guidelines may not align with the current patient population. To evaluate this, electronic databases and gray literature will be searched, including published or unpublished studies of quantitative, qualitative or mixed-methods research designs. Team members will screen the literature and abstract the data. Results will present a numerical account of the amount, type, and distribution of the studies included and a thematic analysis and concept map of the results. This review represents the first attempt to map the available literature on stroke rehabilitation and multimorbidity, and identify gaps in the existing research. The results will be relevant for knowledge users concerned with stroke rehabilitation by expanding the understanding of the current evidence.

Five randomized trials proving the efficacy and safety of mechanical embolectomy for ischemic stroke within 8hours used differing radiological methods to select patients. We aimed to evaluate the proportion of patients in clinical practice that would meet radiological criteria for inclusion in these trials. Retrospective study of ischemic stroke patients at a large academic medical center who were considered for endovascular stroke therapy based on confirmed intracranial large vessel occlusion from April 2010-November 2014. All patients underwent computed tomography (CT) perfusion and CT angiogram. Of 119 patients, median age was 69 years (IQR 57-79) and median NIHSS 18 (IQR 14-21). Most patients had ASPECTS≥6 (n=105, 88.2%). All 119 patients met radiological criteria for MR CLEAN while 105 (88.2%) met criteria for SWIFT-PRIME, 96 (80.7%) for REVASCAT, 80/116 (69.0%) for EXTEND-IA, and 74 (62.2%) for ESCAPE. About half (n=58,48.7%) were treated with IV rtPA and 66 (56%) underwent endovascular therapy. Any intracranial hemorrhage was more common in patients undergoing endovascular therapy than in those who were not (36% vs. 17%, P=0.034). The frequency of symptomatic intracranial hemorrhage (ICH) did not significantly differ between these groups (6% vs. 4%, P=0.691). The proportion of patients with acute stroke and large vessel occlusion presenting within 8 hours that would meet radiological criteria for endovascular stroke trials varies considerably (62-100%) in a cohort outside of clinical trials from an academic comprehensive stroke center. Thus, the radiological criteria used for candidate selection in daily practice will greatly influence the proportion of patients treated with endovascular therapy.

Full Text Available Cerebrovascular accident is a frequent cause of death and disability in most parts of the globe. The incidence of cerebrovascular diseases increases with age and the number of strokes is projected to increase as the elderly population grows. This study was undertaken to determine the type of stroke and also to relate the risks factors associated with stroke. Hundred consecutive patients presenting with stroke in the emergency department / neurology clinic were subjected to computed tomography scan of the brain. Sixty – four patients had ischemic infarct and 36 had intracranial hemorrhage which included 2 patients with subarachnoid hemorrhage and 1 with underlying cavernous angioma. Ischemic stroke was thus commoner than hemorrhagic stroke. Previous infarct or lacunes were noted in 25 % of the patients presenting with stroke. Risk factors were present in most (77 % of the patients presenting with stroke. Among the various risk factors, the single most common was smoking seen in 38 cases, followed by hypertension in 28 cases, obesity in 8 cases and diabetes in 3 cases. Twenty- one patients had multiple combinations of the above risk factors. Among the multiple risk factors, combination of alcohol and smoking was the commonest seen in 11 cases, followed by hypertension and obesity in 8 cases and alcohol with obesity in 2 cases. Change in lifestyle and eating habits may thus help reduce the incidence of stroke. Journal of College of Medical Sciences-Nepal,2012,Vol-8,No-2, 24-31 DOI: http://dx.doi.org/10.3126/jcmsn.v8i2.6834
To examine the contribution of balance ability, muscle strength, and exercise endurance to performance in the timed-sit-to-stand test among chronic hemiparetic subjects. A cross-sectional study with 68 community-dwelling stroke survivors. By using Pearson correlation coefficient, the five-times-sit-to-stand (FTSTS) test scores showed the highest negative correlation with Berg Balance Scale scores (r = -0.837, P test (r = -0.598, P Balance Scale scores only (r = -0.630, P balance confidence, showed that FTSTS scores were independently associated with Berg Balance Scale scores (beta = -0.630, P test were not significant predictors of FTSTS scores. The whole model could explain 71% of the variance in FTSTS scores. This is the first study documenting the importance of balance ability, not muscle strength and exercise endurance, as an important determinant of performance on the FTSTS test by community-dwelling stroke patients. These findings suggest that the FTSTS test may be a more appropriate proxy indicator of balance performance in chronic community-dwelling stroke subjects.

Impaired motor and functional activity following stroke often has negative impacts on the patient, the family and society. The available rehabilitation programs for stroke patients are reviewed. Conventional rehabilitation strategies (Bobath, Brunnstrom, proprioception neuromuscular facilitation, motor relearning and function-based principles) are the mainstream tactics in clinical practices. Numerous advanced strategies for sensory-motor functional enhancement, including electrical stimulation, electromyographic biofeedback, constraint-induced movement therapy, robotics-aided systems, virtual reality, intermittent compression, partial body weight supported treadmill training and thermal stimulation, are being developed and incorporated into conventional rehabilitation programs. The concept of combining valuable rehabilitative procedures into "a training package", based on the patient's functional status during different recovery phases after stroke is proposed. Integrated sensorimotor rehabilitation programs with appropriate temporal arrangements might provide great functional benefits for stroke patients.

Stroke significantly affects thousands of individuals annually, leading to considerable physical impairment and functional disability. Gait is one of the most important activities of daily living affected in stroke survivors. Recent technological developments in powered robotics exoskeletons can create powerful adjunctive tools for rehabilitation and potentially accelerate functional recovery. Here, we present the development and evaluation of a novel lower limb robotic exoskeleton, namely H2 (Technaid S.L., Spain), for gait rehabilitation in stroke survivors. H2 has six actuated joints and is designed to allow intensive overground gait training. An assistive gait control algorithm was developed to create a force field along a desired trajectory, only applying torque when patients deviate from the prescribed movement pattern. The device was evaluated in 3 hemiparetic stroke patients across 4 weeks of training per individual (approximately 12 sessions). The study was approved by the Institutional Review Board at the University of Houston. The main objective of this initial pre-clinical study was to evaluate the safety and usability of the exoskeleton. A Likert scale was used to measure patient's perception about the easy of use of the device. Three stroke patients completed the study. The training was well tolerated and no adverse events occurred. Early findings demonstrate that H2 appears to be safe and easy to use in the participants of this study. The overground training environment employed as a means to enhance active patient engagement proved to be challenging and exciting for patients. These results are promising and encourage future rehabilitation training with a larger cohort of patients. The developed exoskeleton enables longitudinal overground training of walking in hemiparetic patients after stroke. The system is robust and safe when applied to assist a stroke patient performing an overground walking task. Such device opens the opportunity to study means
The majority of strokes are due to ischaemia. Risk factors include atrial fibrillation, hypertension and smoking. The incidence can be reduced by addressing these risk factors. This study examines the prevalence of risk factors and their treatment in a cohort of patients with ischaemic stroke registered on a Dublin stroke database.
Full Text Available Background. Previous evidence on factors and causes of readmissions associated with high-impact users of stroke is scanty. The aim of the study was to investigate common causes and pattern of short- and long-term readmissions stroke patients by conducting a systematic review of studies using hospital administrative data. Common risk factors associated with the change of readmission rate were also examined. Methods. The literature search was conducted from 15 February to 15 March 2016 using various databases, such as Medline, Embase, and Web of Science. Results. There were a total of 24 studies (n=2,126,617 included in the review. Only 4 studies assessed causes of readmissions in stroke patients with the follow-up duration from 30 days to 5 years. Common causes of readmissions in majority of the studies were recurrent stroke, infections, and cardiac conditions. Common patient-related risk factors associated with increased readmission rate were age and history of coronary heart disease, heart failure, renal disease, respiratory disease, peripheral arterial disease, and diabetes. Among stroke-related factors, length of stay of index stroke admission was associated with increased readmission rate, followed by bowel incontinence, feeding tube, and urinary catheter. Conclusion. Although risk factors and common causes of readmission were identified, none of the previous studies investigated causes and their sequence of readmissions among high-impact stroke users.

Early identification of patients with stroke-induced aphasia is essential because it is a significant disability affecting daily life and is linked to poor functional outcome after stroke. However, most patients with stroke are unable to undergo aphasia evaluation and detection and therefore remain undiagnosed. The purpose of this study is to develop a valid, reliable mobile aphasia screening test (MAST) for patients in remote locations. To accomplish this, we enrolled patients with (n=30) and without (n=30) stroke-induced aphasia. A MAST, which adopted the Korean version of the shortened version of the Frenchay Aphasia Screening Test (K-FAST), was designed as an iPad(®) (Apple, Cupertino, CA) application. To validate the MAST, we compared its performance with that of the Korean version of the Western Aphasia Battery (K-WAB) and conventional shortened FAST paper version (K-FAST). We analyzed interrater and internal reliability, using Cronbach's alpha coefficient, and assessed the diagnostic sensitivity, specificity, and power. There was significant correlation between K-FAST and MAST (intraclass correlation coefficient [ICC]=0.995, paphasia in patients with stroke. This telescreening test may overcome the limitations of test administration and may be a convenient and cost-effective alternative to the existing aphasia screening tests for patients with stroke.
Full Text Available Abstract Background The low rates of hypertension treatment and control, partly due to its unawareness, are the main causes of the high stroke incidence in China. The purpose of this study was to evaluate hypertension unawareness amongst patients with first-ever stroke and to detect factors associated with its unawareness. Methods We selected those diagnosed with hypertension from patients with first-ever stroke registered in the Nanjing Stroke Registry Program between 2004 and 2014. These hypertensives were divided as being aware or unaware of their hypertension by using a brief questionnaire conducted shortly after the stroke. Multivariate logistic regression analysis was performed to identify potential factors associated with hypertension unawareness. Results Of the 5309 patients with first-ever stroke, 3732 (70.3 % were diagnosed with hypertension. Among which, 593 (15.9 % were unaware of their hypertension at the time of stroke onset. Lower-level of education (primary school or illiteracy and smoking were associated positively with hypertension unawareness; while advanced age, overweight, diabetes mellitus, heart diseases and family history of stroke were associated negatively with hypertension unawareness. Annual data analyzed indicated that the rate of hypertension awareness increased during the past 11 years (r = 0.613, P = 0.045 for trends. Conclusions A substantial proportion (15.9 % of Chinese patients with hypertension had not been aware of this covert risk until an overt stroke occurred. Hypertension unawareness was associated with lower educational levels and smoking, which address the importance of health education especially in these individuals.

Early determination of hospital discharge disposition status at an acute admission is extremely important for stroke management and the eventual outcomes of patients with stroke. We investigated the hospital discharge disposition of patients with stroke residing in Tennessee and developed a predictive tool for clinical adoption. Our investigational aims were to evaluate the association of selected patient characteristics with hospital discharge disposition status and predict such status at the time of an acute stroke admission. We analyzed 127,581 records of patients with stroke hospitalized between 2010 and 2014. Logistic regression was used to generate odds ratios with 95% confidence intervals to examine the factor outcome association. An easy-to-use clinical predictive tool was built by using integer-based risk scores derived from coefficients of multivariable logistic regression. Among the 127,581 records of patients with stroke, 86,114 (67.5%) indicated home discharge and 41,467 (32.5%) corresponded to facility discharge. All considered patient characteristics had significant correlations with hospital discharge disposition status. Patients were at greater odds of being discharged to another facility if they were women; older; black; patients with a subarachnoid or intracerebral hemorrhage; those with the comorbidities of diabetes mellitus, heart disease, hypertension, chronic kidney disease, arrhythmia, or depression; those transferred from another hospital; or patients with Medicare as the primary payer. A predictive tool had a discriminatory capability with area under the curve estimates of 0.737 and 0.724 for derivation and validation cohorts, respectively. Our investigation revealed that the hospital discharge disposition pattern of patients with stroke in Tennessee was associated with the key patient characteristics of selected demographics, clinical indicators, and insurance status. These analyses resulted in the development of an easy-to-use predictive

Transthoracic echocardiography (TTE) is routinely performed to look for the cardiac sources of emboli in many Western stroke centers. Due to a limitation of resources in Thailand, echocardiography is done in only some patients with acute ischemic stroke. The purpose of this study is to evaluate the need for cardiac investigations, especially TTE, in Thai patients with acute ischemic stroke. Two-hundred and seven patients with acute ischemic stroke or transient ischemic attack (TIA), who had TTE results during August 2006 to November 2008, were studied. Patients were divided into 2 groups by the risk of cardioembolism: low- versus high-risk groups. All echocardiography results were reviewed and classified by the need for management change following the echocardiography. Abnormal TTE results indicating a need for change in management were found in 4% (4/102) and 18% (18/105) in low- and high- risk patients, respectively The results of ECG alone led to change in management in 17% (36 patients). Atrial fibrillation was the most common cause of cardioembolism, which was found in 35 patients (17%). Because of limited resources in Thailand, ECG should be routinely performed on all ischemic stroke patients and TTE in patients with high risk for cardioembolism. However larger studies are still needed to clarify the benefits of echocardiography in low-risk patients.

Impaired motor and functional activity following stroke often has negative impacts on the patient, the family and society. The available rehabilitation programs for stroke patients are reviewed. Conventional rehabilitation strategies (Bobath, Brunnstrom, proprioception neuromuscular facilitation, motor relearning and function-based principles) are the mainstream tactics in clinical practices. Numerous advanced strategies for sensory-motor functional enhancement, including electrical stimulation, electromyographic biofeedback, constraint-induced movement therapy, robotics-aided systems, virtual reality, intermittent compression, partial body weight supported treadmill training and thermal stimulation, are being developed and incorporated into conventional rehabilitation programs. The concept of combining valuable rehabilitative procedures into “a training package”, based on the patient’s functional status during different recovery phases after stroke is proposed. Integrated sensorimotor rehabilitation programs with appropriate temporal arrangements might provide great functional benefits for stroke patients. PMID:25133141

BACKGROUND: Helicopters are widely used for interhospital transfers of stroke patients, but the benefit is sparsely documented. We hypothesised that helicopter transport would reduce system delay to thrombolytic treatment at the regional stroke centre. METHODS: In this prospective controlled...... observational study, we included patients referred to a stroke centre if their ground transport time exceeded 30 min, or they were transported by a secondarily dispatched, physician-staffed helicopter. The primary endpoint was time from telephone contact to triaging neurologist to arrival in the stroke centre....... Secondary endpoints included modified Rankin Scale at 3 months, 30-day and 1-year mortality. RESULTS: A total of 330 patients were included; 265 with ground transport and 65 with helicopter, of which 87 (33%) and 22 (34%), received thrombolysis, respectively (p=0.88). Time from contact to triaging...

Cerebrovascular disease is a major cause of mortality world-wide, and the prevalence is expected to increase as a result of projected demographic trends. Aggressive antihypertensive therapy is one intervention that has proven highly effective in reducing the risk of stroke, with relatively small blood pressure reductions affording measurable benefit even in patients not conventionally considered hypertensive. Comparative clinical trials are revealing evidence of differential impacts of antihypertensive classes on the incidence of cerebrovascular disease that will probably be important for therapeutic choice in patients with risk factors for stroke. In particular, the role of the renin-angiotensin system in cerebrovascular disease has come under scrutiny as a result of evidence that angiotensin II receptor blockers (ARBs), but perhaps not angiotensin converting enzyme inhibitors, can reduce the risk of a first stroke to a greater degree than might be expected from their effects on blood pressure alone. Although preclinical evidence suggests that there are differential effects of the type 1 and type 2 receptor activation, the clinical relevance of this is not yet known. Furthermore, the effect on the incidence of stroke conferred by blood pressure control in the early morning hours - the time when the incidence of strokes peaks--has not been tested. Some evidence for the beneficial effect of an ARB on secondary stroke prevention comes from the MOrbidity and mortality after Stroke --Eprosartan compared with nitrendipine in Secondary prevention study (MOSES), which showed that the ARB protected against cerebro- and cardiovascular events in hypertensive patients with a previous stroke over and above the protection offered by blood pressure control. These hypotheses are among those being examined in two current large-scale trials: the Prevention Regimen For Effectively avoiding Second Strokes (PRoFESS), and The ONgoing Telmisartan Alone and in combination with Ramipril

Full Text Available Introduction. Our aim was to analyze our clinical experience with dabigatran etexilate in secondary stroke prevention. Methods. We retrospectively included patients starting dabigatran etexilate for secondary stroke prevention from March 2010 to December 2012. Efficacy and safety variables were registered. Results. 106 patients were included, median follow-up of 12 months (range 1–31. Fifty-six females (52.8%, mean age 76.4 (range 50–95, SD 9.8, median CHADS2 4 (range 2–6, CHA2DS2-VASc 5 (range 2–9, and HAS-BLED 2 (range 1–5. Indication for dabigatran etexilate was ischemic stroke in 101 patients and acute cerebral hemorrhage (CH due to warfarin in 5 (4.7%. Dabigatran etexilate 110 mg bid was prescribed in 71 cases (67% and 150 mg bid was prescribed in the remaining. Seventeen patients (16% suffered 20 complications during follow-up. Ischemic complications (10 were 6 transient ischemic attacks (TIA, 3 ischemic strokes, and 1 acute coronary syndrome. Hemorrhagic complications (10 were CH (1, gastrointestinal bleeding (6, mild hematuria (2, and mild metrorrhagia (1, leading to dabigatran etexilate discontinuation in 3 patients. Patients with previous CH remained uneventful. Three patients died (pneumonia, congestive heart failure, and acute cholecystitis and 9 were lost during follow-up. Conclusions. Dabigatran etexilate was safe and effective in secondary stroke prevention in clinical practice, including a small number of patients with previous history of CH.

The combination protocol of repetitive transcranial magnetic stimulation (RTMS) and intensive occupational therapy (OT) improves motor function of the paretic upper limb in poststroke patients. However, the effect of RTMS/OT on motor neuron excitability remains to be investigated. The purpose of this study was to determine the effect of 15-day application of RTMS/OT on motor neuron excitability in such patients using neurophysiological studies including F-wave parameter measurements. Ten poststroke patients with spastic upper limb hemiparesis were studied (mean age: 57.4 ± 8.1 years, ± SD). Patients were hospitalized for 15 days to receive RTMS/OT. One session of 40-min low-frequency RTMS and two sessions of 120-min intensive OT were provided daily. Neurophysiological studies including F-wave parameters measurements were performed on the days of admission/discharge. Motor function and spasticity of the affected upper limb were evaluated on the same time points. RTMS/OT significantly improved motor function of the affected upper limb. RTMS/OT decreased the modified Ashworth scale (MAS) in the affected upper limb (p < 0.05), but did not change F-wave frequency in either upper limb. However, both F-mean/M ratio and F-max/M ratio significantly decreased in the affected upper limb (all p < 0.05). The 15-day protocol of LF-RTMS/OT produced significant reduction of motor neuron excitability. RTMS/OT can potentially produce significant reduction in upper limb spasticity in the affected upper limb, although this finding should be confirmed in a larger number of patients.

To determine the influence of initially lowered orientation on rehabilitation outcome in stroke patients, and how decreased orientation 6 months after stroke influences ADL and social activities. Prospective, consecutive, and community based. A stroke unit receiving all acute stroke patients from a well-defined catchment area. All stages of rehabilitation were completed within the unit. 524 patients with acute stroke. Basic ADL assessed by the Barthel Index (BI) at discharge; discharge placement; higher level ADL and social functions assessed by the Frenchay Activity Index(FAI) at a 6-month follow-up. The independent influence of orientation in acute stroke on rehabilitation outcome was analyzed with multiple linear and logistic regression models, using initial stroke severity (Scandinavian Neurologic Stroke Scale), initial BI, age, sex, comorbidity, prior stroke, and marital status as covariates. A one-point decrease in orientation decreased BI with 9 points (coefficient b=8.66, SE(b)=1.02,porientation at this point still exerted a marked, negative influence on ADL and social functions (BI: coefficient b=12.06, SE(b)=1.95,porientation influences basic ADL and higher level ADL and social activities in acute as well as chronic stroke. This finding suggests that rehabilitation of memory and attention might be relevant in stroke patients with impaired orientation.

Comprehensive stroke systems of care include routing to the nearest designated stroke center hospital, bypassing non-designated hospitals. Routing protocols are implemented at the state or county level and vary in qualification criteria and determination of destination hospital. We surveyed all counties in the state of California for presence and characteristics of their prehospital stroke routing protocols. Each county's local emergency medical services agency (LEMSA) was queried for the presence of a stroke routing protocol. We reviewed these protocols for method of stroke identification and criteria for patient transport to a stroke center. Thirty-three LEMSAs serve 58 counties in California with populations ranging from 1,175 to nearly 10 million. Fifteen LEMSAs (45%) had stroke routing protocols, covering 23 counties (40%) and 68% of the state population. Counties with protocols had higher population density (1,500 vs. 140 persons per square mile). In the six counties without designated stroke centers, patients meeting criteria were transported out of county. Stroke identification in the field was achieved using the Cincinnati Prehospital Stroke Screen in 72%, Los Angeles Prehospital Stroke Screen in 7% and a county-specific protocol in 22%. California EMS prehospital acute stroke routing protocols cover 68% of the state population and vary in characteristics including activation by symptom onset time and destination facility features, reflecting matching of system design to local geographic resources.

Studies suggest that ethnicity and racial factors has an important role in the variation in epidemiology of stroke. The present study was conducted to assess the subtypes, risk factors, and outcome of stroke in the tribal community of Jharkhand state and to compare it with that in the non-tribals from the same geographical location. We carried out a hospital-based prospective observational study at Rajendra Institute of Medical Sciences-Ranchi. Patients of acute stroke, reporting to the medical outpatient department and emergency department from January 1, 2006 to December 31, 2010 were studied. Computed tomography scan was done immediately and again after 24 h to confirm the diagnosis of stroke. To compare the findings between tribal and non-tribal patients, we used chi-square test/Fisher exact test as appropriate. Of the total 1156 patients included in the study, 536 were tribals, while 620 were non-tribals. Significant differences were found in tribal stroke patients as compared with non-tribals: mean age of tribal subjects was 53·8 years (60·8 years in non-tribals); stroke in young individual was present in 25% of tribal subjects (17% in non-tribals, P = 0·01); primary intracerebral hemorrhage variety was present in 31% of tribals (18% in non-tribals, P-value tribal subjects (35% among non-tribals, P = 0·02). Hypertension and alcohol abuse was found to be associated with intracerebral hemorrhage in tribal subjects, although no such association was found in non-tribals. Tribals have early onset, poor outcomes and higher proportion of ICH compared to non-tribals.

Full Text Available Stroke is a global burden. It is not known whether patients who are most at risk of stroke (recurrent stroke or recurrent transient ischaemic attack have enough knowledge of stroke risk factors and warning signs. The aim of this study was to assess the knowledge of stroke risk factors and warning signs in this high-risk population. We performed a cross-sectional questionnaire-based study of patients with recurrent stroke or recurrent TIA admitted to Srinagarind Hospital and Khon Kaen Hospital, Thailand. A total of 140 patients were included in the study (age 65.6±11.3 years [mean ± SD], 62 females. Using an open-ended questionnaire, nearly one-third of patients (31.4% could not name any risk factors for stroke. The most commonly recognized risk factors were hypertension (35%, dyslipidemia (28.6%, and diabetes (22.9%. Regarding stroke warning signs, the most commonly recognized warning signs were sudden unilateral weakness (61.4%, sudden trouble with speaking (25.7%, and sudden trouble with walking, loss of balance, or dizziness (21.4%. Nineteen patients (13.6% could not identify any warning signs. The results showed that knowledge of stroke obtained from open-ended questionnaires is still unsatisfactory. The healthcare provider should provide structured interventions to increase knowledge and awareness of stroke in these patients.

Limited data on stroke exist for Costa Rica. Therefore, we created a stroke registry out of patients with stroke seen in the Acute Stroke Unit of the Hospital Calderon Guardia. We analyzed 1319 patients enrolled over a 7-year period, which incorporated demographic, clinical, laboratory, and neuroimaging data. The mean age of patients with stroke was 68.0 ± 15.5 years. Seven hundred twenty-five were men and the age range was 13-104 years. The most prevalent risk factors were hypertension (78.8%), dyslipidemia (36.3%), and diabetes (31.9%). Fifteen percent had atrial fibrillation and 24.7% had a previous stroke or transient ischemic attack. Prevalence of hypertension and atrial fibrillation increased with age; however, younger patients were more associated with thrombophilia. We documented 962 (72.9%) ischemic and 270 (20.5%) hemorrhagic strokes. Of the ischemic strokes, 174 (18.1%) were considered secondary to large-artery atherothrombosis, 175 (18.2%) were due to cardiac embolism, 19 (2.0%) were due to lacunar infarcts, and 25 (2.6%) were due to other determined causes. Five hundred sixty-nine (59.1%) remained undetermined. Atherothrombotic strokes were mostly associated with dyslipidemia, diabetes, metabolic syndrome, and obesity, whereas lacunar infarcts were associated with hypertension, smoking, sedentary lifestyle, and previous stroke or transient ischemic attack. Of our patients, 69.9% scored between 0 and 9 in the initial National Institutes of Health Stroke Scale (NIHSS). We found differences in sociodemographic features, risk factors, and stroke severity among stroke subtypes. Risk factor prevalence was similar to other registries involving Hispanic populations.

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac dysrhythmia, with a lifetime risk of 25%, and it is a well-known independent risk factor for ischemic stroke. Over the last 15 years, efforts have been made to initiate relevant treatment in patients with AF. A retrospective study....... RESULTS: A total of 4134 patients were included in the study. Overall, the yearly proportion of patients with known AF varied between 9% and 18%. No significant change was observed (P = .511). The proportion of patients with known AF treated with anticoagulants at the time of the stroke and the proportion...... was observed. An explanation could be an increase in the prevalence of AF in the general population, leaving the proportion of patients admitted with ischemic stroke unchanged. Other risk factors have been sought reduced as well with the implementation of national guidelines regarding hypertension...

To quantify the availability of informal caregivers in surviving stroke patients residing at home in Belgium. National estimates on the availability of informal caregivers were made using data from a nationwide observational registration of family physicians working in sentinel practices and a nationwide administrative database for reimbursement of hospitals in Belgium. A total of 189 Belgian family physicians (FPs) from 141 practices participated in the study and recorded 326 patients (144 men and 182 women) with stroke. These FPs reach 1.5% of the Belgian population. After 1 month, 71% of the male and 75% of the female stroke survivors received support from family caregivers (p = 0.547). After 6 months, the percentage of male patients who received support from family caregivers decreased to 60% compared with 75% in female (p = 0.038). Of all patients with stroke admitted to Belgian hospitals during the reference year 2009 (n = 16.437), 8.997 returned home. Based on the findings from the sentinel practices, it is estimated that a mean of 73% (n = 6.568) and 67.5% (n = 6.073) of surviving patients with stroke can rely on informal caregivers in their home setting after one and 6 months, respectively. A vast majority of surviving stroke patients in Belgium can rely on informal caregivers in their home setting, but their availability rapidly decreases 6 months after the event. These findings underline the importance of proactive health policy making in stroke care taking into account the potentially decreasing number of available informal caregivers in the decades to come. © 2013 Nordic College of Caring Science.

To analyze how acupuncture therapy affects balance in patients experiencing their first stroke and to identify the stroke group with greatest improvement in balance after acupuncture intervention. Retrospective case-control study. Ward of a medical university hospital. A total of 629 stroke patients were enrolled initially; 345 patients met the study criteria and 132 were analyzed (66 each in the study and control groups). The study group received physiotherapy combined with acupuncture and the control group received only physiotherapy. The Postural Assessment Scale for Stroke patients (PASS) was used to evaluate balance. This balance scale system can be subdivided into static balance (PASS-MP, maintain posture) and dynamic balance (PASS-CP, change posture). This study revealed no statistically significant improvement of balance in the study group (t test). When patients with high Brunnstrom stage (Br stage) and low Br stage were analyzed separately, once again no statistical difference was detected between the study and control groups of those with high Br stage. However, among low-Br stage patients, the study group showed significant improvement in static balance (mean PASS-MP score±standard deviation: 4.7±3.7) compared with the control group (PASS-MP score: 2.8±2.7) (pstroke patients with a low Br stage, acupuncture therapy can improve static balance during rehabilitation. However, the effect on balance was limited among high-Br stage patients. This study provides information valuable to patients with hemiplegic stroke because it suggests that acupuncture can be used to improve balance. A prospective double-blind, randomized, controlled study design is recommended for future studies in patients with hemiplegic stroke.

Full Text Available The study objective is to conduct a pharmacoeconomic analysis of naftidrofuryl effectiveness in patients with ischemic stroke.Materials and methods. The work is based on the results of clinical studies of effectiveness, tolerability, and safety of naftidrofuryl in patients who suffered an ischemic stroke. The study design included data on 1000 patients of 45 and older with first-time acute cerebrovascular disease of ischemic type.Results. Direct medical costs for the chosen patient cohort per the Standard of stroke treatment current at the time of the study were 730 575 189 rubles, in case of naftidrofuryl inclusion they were 476 467 620 rubles. Cost minimization is 254 107 569 rubles. Indirect nonmedical costs associated with temporary incapacity for work for treatment per the Standard of stroke treatment were 124 156 950 rubles, and 64 559 180 rubles for naftidrofuryl use which demonstrates the drug’s economic benefit. Budget impact analysis has shown that the possible savings constitute 7.59 %.Conclusion. Inclusion of naftidrofuryl into treatment of patients with ischemic stroke is justified as it decreases duration of rehabilitation. This leads to a positive economic effect expressed as decreased direct and non-direct medical costs.

After adjustment for stroke severity, C-reactive protein, age, NT-proBNP and prior heart and/or renal failure, hsTnT levels were not a significant predictor of long-term all-cause or cardiovascular mortality. Conclusion: Elevated levels of hsTnT are frequently present......Background: Newly developed troponin assays have superior diagnostic and prognostic performance in acute coronary syndrome (ACS), when compared to conventional troponin assays; however, highly sensitive troponin has not been evaluated in patients with acute ischemic stroke. Methods: Highly...... sensitive troponin T (hsTnT) was measured daily during the first 4 days in 193 consecutive patients with acute ischemic stroke without overt ACS or atrial fibrillation. The patients were previously tested normal with a fourth-generation TnT assay. The patients were followed for 47 months, with all...

Full Text Available Clinical and radiologic asymmetric arthritic differences between paralyzed and nonparalyzed limbs of stroke patients have been reported. Arthritic pathology aggravates motor dysfunction and compromises rehabilitation. Musculoskeletal ultrasonography plays an important role in showing soft tissue and the articular cartilage of the knee. Fifty-nine patients with either ischemic or hemorrhagic stroke-induced right or left hemiplegia were recruited to evaluate soft-tissue and intra-articular cartilage changes in hemiplegic knees of stroke patients using ultrasonography. An additional 15 subjects (30 knees without knee disease or a history of knee trauma or surgery were used as controls. There were significant differences in suprapatellar effusion and patellar tendinitis between hemiplegic and nonhemiplegic knees. Suprapatellar effusion and pes anserinus tendinitis were correlated with Brunnstrom stage. The length of time since stroke onset was not significantly correlated with positive ultrasonographic findings in hemiplegic knees. In conclusion, ultrasonography is useful for detecting periarticular soft-tissue changes and intra-articular lesions in hemiplegic knees of stroke patients.
Full Text Available Various degrees of neural reorganization may occur in affected and unaffected hemispheres in the early phase after stroke and several months later. Recent literature suggests to apply a stratification based on lesion location and to consider patients with cortico-subcortical and subcortical strokes separately: different lesion location may also influence therapeutic response. In this study we used a longitudinal approach to perform TMS assessment (Motor Evoked Potentials, MEP, and Silent Period, SP and clinical evaluations (Barthel Index, Fugl-Meyer Assessment for upper limb motor function and Wolf Motor Function Test in 10 cortical-subcortical and 10 subcortical ischemic stroke patients. Evaluations were performed in a window between 10 and 45 days (t0 and at 3 months after the acute event (t1. Our main finding is that 3 months after the acute event patients affected by subcortical stroke presented a reduction in contralateral SP duration in the unaffected hemisphere; this trend is related to clinical improvement of upper limb motor function. In conclusion, SP proved to be a valid parameter to characterize cortical reorganization patterns in stroke survivors and provided useful information about motor recovery within three months in subcortical patients.

Stroke is regularly accompanied by dysphagia and other factors associated with decreased nutritional intake. Dysphagia with aspiration pneumonia and insufficient nutritional intake lead to worse outcome after stroke.This guideline is the first chapter of the guideline "Clinical Nutrition in Neurology" of the German Society for Clinical Nutrition (DGEM) which itself is one part of a comprehensive guideline about all areas of Clinical Nutrition. The thirty-one recommendations of the guideline are based on a systematic literature search and review, last updated December 31, 2011. All recommendations were discussed and consented at several consensus conferences with the entire DGEM guideline group. The recommendations underline the importance of an early screening and assessment of dysphagia and give advice for an evidence based and comprehensive nutritional management to avoid aspiration, malnutrition and dehydration.

Background Predicting recanalization success for patients undergoing endovascular treatment for acute ischemic stroke is of significant interest. Studies have previously correlated the success of recanalization with the density of the clot. We evaluated clot density and its relationship to revascularization success and stroke etiology. Methods We conducted a retrospective review of 118 patients undergoing intra-arterial therapy for acute ischemic stroke. Mean and maximum thrombus density was measured by drawing a circular region of interest on an axial slice of a non-contrast computed tomography scan. T-tests were used to compare clot density to recanalization success or to stroke etiology, namely large artery atherosclerosis and cardioembolism. Recanalization success was compared in four device groups: aspiration, stent retriever, aspiration and stent retriever, and all other. Results There was no significant difference in the mean clot density in patients with successful ( n = 80) versus unsuccessful recanalization ( n = 38, 50.1 ± 7.4 Hounsfield unit (HU) vs. 53 ± 12.7 HU; P = 0.17). Comparing the large artery thromboembolism ( n = 35) to the cardioembolic etiology group ( n = 56), there was no significant difference in mean clot density (51.5 ± 7.7 HU vs. 49.7 ± 8.5 HU; P = 0.31). A subgroup analysis of middle cerebral artery occlusions ( n = 65) showed similar, non-statistically significant differences between groups. There was no difference in the rate of recanalization success in patients with a mean clot density greater than 50 HU or less than 50 HU in each of the four device groups. Conclusions There was no relationship between clot density and revascularization success or stroke etiology in our study. More research is needed to determine if clot density can predict recanalization rates or indicate etiology.

Approximately 30% of all stroke patients suffer from post-stroke visual impairment. Hemianopia is the most common symptom, but also neglect, diplopia, reduced visual acuity, ptosis, anisocoria, and nystagmus are frequent. Partial or complete recovery of visual disorders can occur, but many patients suffer permanent disability. This disability is often less evident than impairment of motor and speech functions, but is negatively correlated with rehabilitation outcome and can lead to a significant reduction in day-to-day functioning. To be visually impaired after stroke reduces quality of life and causes social isolation because of difficulties in navigating/orientating in the surroundings. A thorough diagnosis including targeted examination and later follow-up with eye examination and perimetry is essential in order to establish the extent of the visual impairment and to select the best rehabilitation strategy. Patients seem to profit from visual rehabilitation focused on coping strategies. © 2012 John Wiley & Sons A/S.

Neurodevelopmental treatment (NDT) is the most used rehabilitation approach in the treatment of patients with stroke in the Western world today, despite the lack of evidence for its efficacy. The aim of this study was to conduct an intervention check and measure the nurses' competence, in positioning stroke patients according to the NDT approach. The sample consisted of 144 nurses in six neurological wards who were observed while positioning stroke patients according to the NDT approach. The nurses' combined mean competence scores within the wards was 195 (70%) of 280 (100%) possible, and for each ward the mean score varied between 181 (65%) and 206 (74%). This study indicates that nurses working in hospitals where the NDT approach has been implemented have the knowledge and skills to provide NDT nursing.

In this study, the virtual reality (VR) proprioception rehabilitation system was developed for stroke patients to use proprioception feedback in upper limb rehabilitation by blocking visual feedback. To evaluate its therapeutic effect, 10 stroke patients (onset>3 month) trained proprioception feedback rehabilitation for one week and visual feedback rehabilitation for another week in random order. Proprioception functions were checked before, a week after, and at the end of training. The results show the click count, error distance and total error distance among proprioception evaluation factors were significantly reduced after proprioception feedback training compared to visual feedback training (respectively, p=0.005, p=0.001, and p=0.007). In addition, subjects were significantly improved in conventional behavioral tests after training. In conclusion, we showed the effectiveness and possible use of the VR to recover the proprioception of stroke patients. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Individuals with "minor stroke" lack a dense hemiparesis or aphasia; however, commonly endorse persistent cognitive and motor problems despite low NIHSS scores. They also report problems with mood, energy, and the ability to think clearly that are less well characterized. Socioeconomic factors and stroke severity can influence patient-reported outcomes. In this study we explore patient-reported outcomes and the influence of these factors after minor stroke. Patients returning to clinic post-stroke with an NIHSS of ≤ 4 were administered a scale to quantify problems with daily activities and resulting functional burden, along with measures of fatigue and depression. T-tests, chi square analysis, and linear regression were used to compare functional outcomes of patients to controls (TIA or stroke mimic (n = 40)), and evaluate the association between patient-reported outcomes, stroke characteristics, and socioeconomic factors. 151 stroke patients were seen a mean 83.6 days post-infarct. Patients reported more problems (11.7 versus 6.9, p = 0.02), resulting in higher functional burden (26.5 versus 12.3, p = 0.01), increased depression (p = 0.07), and greater fatigue (p = 0.02) compared to controls. There was no relationship between stroke characteristics (other than NIHSS), baseline education, income, marital status, or living situation and perception of recovery; however, those actively working prior to their stroke reported better outcomes across all categories (p for each <0.02), and differences persisted in multivariable regression models. Prior occupational status may represent an important prognostic indicator for patients with minor stroke. Individuals working at the time of their infarct report better functional outcomes irrespective of age or stroke severity. Copyright © 2017 Elsevier B.V. All rights reserved.

Levels of physical fitness are low after stroke. It is unknown whether improving physical fitness after stroke reduces disability. To determine whether fitness training after stroke reduces death, dependence, and disability. The secondary aims were to determine the effects of training on physical fitness, mobility, physical function, quality of life, mood, and incidence of adverse events. We searched the Cochrane Stroke Group Trials Register (last searched April 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, July 2010), MEDLINE (1966 to March 2010), EMBASE (1980 to March 2010), CINAHL (1982 to March 2010), SPORTDiscus (1949 to March 2010), and five additional databases (March 2010). We also searched ongoing trials registers, handsearched relevant journals and conference proceedings, screened reference lists, and contacted experts in the field. Randomised trials comparing either cardiorespiratory training or resistance training, or both, with no intervention, a non-exercise intervention, or usual care in stroke survivors. Two review authors independently selected trials, assessed quality, and extracted data. We analysed data using random-effects meta-analyses. Diverse outcome measures limited the intended analyses. We included 32 trials, involving 1414 participants, which comprised cardiorespiratory (14 trials, 651 participants), resistance (seven trials, 246 participants), and mixed training interventions (11 trials, 517 participants). Five deaths were reported at the end of the intervention and nine at the end of follow-up. No dependence data were reported. Diverse outcome measures made data pooling difficult. The majority of the estimates of effect were not significant. Cardiorespiratory training involving walking improved maximum walking speed (mean difference (MD) 8.66 metres per minute, 95% confidence interval (CI) 2.98 to 14.34), preferred gait speed (MD 4.68 metres per minute, 95% CI 1.40 to 7.96) and walking

The functional prognosis of patients should be known when planning their rehabilitation treatment. To find the prognostic value of the MSH classification for hemiplegic patients, which is based on the clinical deficits seen after the stroke, and to distinguish between the M group (motor deficit), MS group (motor and sensory deficits) and the MSH group (motor, sensory and homonymous deficits). A prospective analytical study was made of the hemiplegic patients admitted consecutively to the Rehabilitation Department after strokes. The initial examination was made 17 days (CI: 15-19) after the stroke. Satisfactory functional results were considered to be obtaining a Barthel index of > 90 together with the ability to walk unaided on level ground six months after the stroke. Of the 55 patients finally included in the study, 23 were in group M (41.8%) 21 in group MS (38.1%) and 11 patients in group MSH (20.1%). Walking ability and function in the different cohorts showed a statistically significant difference. Whilst 96% of the patients with pure hemiparesia (group M) attained a satisfactory degree of independence in walking, only 54% of the patients with three associated deficits (MSH) achieved this. Even more difference was found with acquired functional independence, since whilst 82% of group M attained a good degree of autonomy in carrying out everyday activities, only 18% of the MSH group achieved this. The remaining patients (MS group) had intermediate results. The MSH classification is, soon after having a stroke, a useful means of determining the functional prognosis of hemiplegic patients.

To investigate the effects of music therapy on depressive mood and anxiety in post-stroke patients and evaluate satisfaction levels of patients and caregivers. Eighteen post-stroke patients, within six months of onset and mini mental status examination score of over 20, participated in this study. Patients were divided into music and control groups. The experimental group participated in the music therapy program for four weeks. Psychological status was evaluated with the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) before and after music therapy. Satisfaction with music therapy was evaluated by a questionnaire. BAI and BDI scores showed a greater decrease in the music group than the control group after music therapy, but only the decrease of BDI scores were statistically significant (p=0.048). Music therapy satisfaction in patients and caregivers was affirmative. Music therapy has a positive effect on mood in post-stroke patients and may be beneficial for mood improvement with stroke. These results are encouraging, but further studies are needed in this field.

Full Text Available A stroke often results in post-stroke dementia, a rapid decline in memory and intelligence causing dysfunctions in daily life. The Chinese medicine doctor uses 4 examinations of inspection, listening, smelling, and feeling to determine the Chinese medicine pattern (CMP. Therefore, the purpose of the present study was to investigate the CMP in patients with post-stroke dementia. A total of 101 stroke patients were examined, consistent with the DSM IV diagnostic criteria of the American Psychiatric Association, as well as the National Institute of Neurological Disorders and Stroke-Association International pour Ia Recherche et I’Enseignement en Neurosciences vascular dementia diagnostic criteria of post-stroke dementia. Results: 100 patients (99.0% were KEDP (kidney essence deficiency pattern, shèn jīng kuī xū zhèng, 腎精虧虛證, 83 patients were AHLYP (ascendant hyperactivity of liver yang pattern, gān yáng shàng kàng zhèng, 肝陽上亢證, 83 patients were QBDP (qi-blood deficiency pattern, qì xuè kuī xū zhèng, 氣血虧虛證, 81 patients were SBOCP (static blood obstructing the collaterals pattern, yū xuè zǔ luò zhèng, 瘀血阻絡證, 72 patients were BSTRP (bowels stagnation turbidity retention pattern, fǔ zhì zhuó liú zhèng, 腑滯濁留證, 50 patients were FHIEP (fire heat interior excess pattern, huǒ rè nèi sheng zhèng, 火熱內盛證, and 39 participants (38.6% were PTOOP (phlegm turbidity obstructing the orifices pattern, tán zhuó zǔ qiào zhèng, 痰濁阻竅證; one to 31 patients have at least 2 CMPs simultaneously.

The American Stroke Association recommends that Emergency Medical Service bypass acute stroke-ready hospital (ASRH)/primary stroke center (PSC) for comprehensive stroke centers (CSCs) when transporting appropriate stroke patients, if the additional travel time is ≤15 minutes. However, data on additional transport time and the effect on hospital census remain unknown. Stroke patients ≥20 years old who were transported from home to an ASRH/PSC or CSC via Emergency Medical Service in 2010 were identified in the Greater Cincinnati area population of 1.3 million. Addresses of all patients' residences and hospitals were geocoded, and estimated travel times were calculated. We estimated the mean differences between the travel time for patients taken to an ASRH/PSC and the theoretical time had they been transported directly to the region's CSC. Of 929 patients with geocoded addresses, 806 were transported via Emergency Medical Service directly to an ASRH/PSC. Mean additional travel time of direct transport to the CSC, compared with transport to an ASRH/PSC, was 7.9±6.8 minutes; 85% would have ≤15 minutes added transport time. Triage of all stroke patients to the CSC would have added 727 patients to the CSC's census in 2010. Limiting triage to the CSC to patients with National Institutes of Health Stroke Scale score of ≥10 within 6 hours of onset would have added 116 patients (2.2 per week) to the CSC's annual census. Emergency Medical Service triage to CSCs based on stroke severity and symptom duration may be feasible. The impact on stroke systems of care and patient outcomes remains to be determined and requires prospective evaluation. © 2017 American Heart Association, Inc.

We investigated how changes in the writing of 14 Korean stroke patients reflect the unique features of the Korean writing system. The Korean writing system, Han-geul, has both linguistic and visuospatial/constructive characteristics. In the visuospatial construction of a syllable, the component consonant(s) and vowel(s) must be arranged from top-to-bottom and/or left-to-right within the form of a square. This syllabic organization, unique to Korean writing, may distinguish dysgraphia in Korean patients from the disorder in other languages, and reveal the effects of stroke on visuospatial/constructive abilities. We compared 2 groups of patients affected by stroke, 1 group with left hemisphere (LH) lesions and the other with right hemisphere (RH) lesions. We instructed them to write from a dictation of 90 monosyllabic stimuli, each presented with a real word cue. Patients had to repeat a target syllable and a word cue, and then to write the target syllable only. Patients with LH and RH lesions produced qualitatively different error patterns. While the LH lesion group produced primarily linguistic errors, visuospatial/constructive errors predominated in the group with RH lesions. With regard to language-specific features, these Korean patients with RH lesions produced diverse visuospatial/constructive errors not commonly observed in dysgraphia of the English language. Language-specific writing errors by Korean stroke patients reflect the unique characteristics of Korean writing, which include the arrangement of strokes and graphemes within a square syllabic form by dimensional and spatial rules. These findings support the notion that the Korean writing system possesses a language-specific nature with both linguistic and visuospatial/constructive processes. Distinctive patterns of dysgraphia in the Korean language also suggest interactivity between linguistic and visuospatial/constructive levels of processing. This study is noteworthy for its systematic description of

Stroke is common and costly, annually depriving the lives and well-being of 800,000 Americans. Despite demonstrated efficacy in clinical trials, questions remain about the safety and clinical effectiveness of various treatment options given patient characteristics, conditions, preferences, and their desired outcomes. The Patient-Centered Research Into Outcomes Stroke Patients Prefer and Effectiveness Research (PROSPER) is a Patient-Centered Outcomes Research Institute-sponsored project designed to help patients, physicians, and other stakeholders make informed decisions regarding stroke care and improve outcomes through patient-centered comparative effectiveness research. The primary outcomes identified and prioritized by stroke patients are "home time" (time spent alive and outside a hospital) and major adverse cardiovascular events. With inputs from stroke patients themselves, a series of comparative safety and effectiveness analyses will be performed across 3 prioritized therapeutic areas identified as important by stroke survivors: oral anticoagulants, statin therapy, and antidepressants. We obtained data from Get With the Guidelines-Stroke linked with Medicare claims and follow-up telephone interviews. Our combined retrospective and prospective research strategy allows the evaluation of the safety and effectiveness of various treatment options and patient-centered longitudinal outcomes. To ensure the rapid translation of findings into clinical practice, results will be disseminated to stroke survivors, caregivers, and health care providers through traditional and social media, including an online decision aid tool. PROSPER is a patient-centered outcome research study guided by patients, caregivers, and the broader health care community. By addressing knowledge gaps in treatment uncertainties through comparative effectiveness research, PROSPER has the potential to improve decision making in stroke care and patient outcomes reflecting individual patient

Full Text Available Malnutrition is common after stroke, usually caused by cognitive disorder, dysphagia, paralysis, sensorimotor disability and visual field defect. Many researches indicate that the initiation of early enteral nutrition in stroke patients would own enormous clinical benefits, including a decrease in the risk of death and infectious diseases, shorter hospital stay and lower health expenditure. However, irregular nutrition management could increase the incidence of hypostatic pneumonia and urinary tract infection. Therefore, both European Society for Parenteral and Enteral Nutrition (ESPEN and American Society for Parenteral and Enteral Nutrition (ASPEN recommended that nutrition screening and assessment and nutrition support be initiated as soon as possible, preferably within 24 h of hospital admission, to improve clinical outcomes. Chinese neurologists and patients have accepted this concept and have done many worthful studies in the past few years. This paper summarized the common methods of nutrition assessment and measurement of interstinal barrier function, in order to monitor the nutritional status of stroke patients, and push the establishment and improvement of nutrition support system for stroke patients in China.

A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions.

Risk factors for first stroke are well established, but less is known about risk factors for recurrent stroke. In the present analysis, we aimed to assess the effect of heart rate and other possible predictors of stroke in a hypertensive population with previous stroke or transient ischemic attack (TIA). The Valsartan Antihypertensive Long-Term Use Evaluation trial was a multicentre, double-masked, randomized controlled, parallel group trial comparing the effects of an angiotensin receptor blocker (valsartan) and a calcium channel blocker (amlodipine) in patients with hypertension and high cardiovascular risk. We used Cox proportional hazard models to investigate the effect of baseline variables on the risk of stroke. Quadratic terms of the continuous variables were entered in the models to test for linearity. Of 15,245 patients included in the trial, 3014 had a previous stroke or TIA at baseline and were included in the present analysis. Stroke recurrence occurred in 239 patients (7.9%) during a median of 4.5 years of follow-up. Resting heart rate (per 10 beats per minute; hazard ratio [HR], 2.78; 95% confidence interval [CI], 1.18-6.58) and diabetes mellitus at baseline (HR, 1.47; 95% CI, 1.03-2.10) were significantly associated with an increased risk of stroke recurrence in the multivariable analysis. In high-risk, hypertensive patients with previous stroke or TIA, resting heart rate was the strongest predictor of recurrent stroke. Copyright © 2014 National Stroke Association.

Adherence to a Mediterranean Diet appears to reduce the risk of cardiovascular disease, cancer, Alzheimer's disease, and Parkinson's disease, as well as the risk of death due to cardiovascular disease. No study has addressed the association between diagnostic subtype of stroke and its severity and adherence to a Mediterranean Diet in subjects with acute ischemic stroke. To evaluate the association between Mediterranean Diet adherence, TOAST subtype, and stroke severity by means of a retrospective study. The type of acute ischemic stroke was classified according to the TOAST criteria. All patients admitted to our ward with acute ischemic stroke completed a 137-item validated food-frequency questionnaire adapted to the Sicilian population. A scale indicating the degree of adherence to the traditional Mediterranean Diet was used (Me-Di score: range 0-9). 198 subjects with acute ischemic stroke and 100 control subjects without stroke. Stroke subjects had a lower mean Mediterranean Diet score compared to 100 controls without stroke. We observed a significant positive correlation between Me-Di score and SSS score, whereas we observed a negative relationship between Me-Di score and NIHSS and Rankin scores. Subjects with atherosclerotic (LAAS) stroke subtype had a lower mean Me-Di score compared to subjects with other subtypes. Multinomial logistic regression analysis in a simple model showed a negative relationship between MeDi score and LAAS subtype vs. lacunar subtype (and LAAS vs. cardio-embolic subtype). Patients with lower adherence to a Mediterranean Diet are more likely to have an atherosclerotic (LAAS) stroke, a worse clinical presentation of ischemic stroke at admission and a higher Rankin score at discharge.

Full Text Available Abstract. Tuberculous meningitis (TBM is a devastating disease. TBM occurs more commonly in HIV infected patients. The influence of HIV co-infection on clinical manifestations and outcome of TBM is not well defined. Yet, some differences have been observed and stroke has been recorded to occur more frequently. This study reports on an HIV infected Caucasian female with lung, meningeal tuberculosis and stroke due to a cortical sub-cortical ischemic lesion.TBM was documented in the absence of neurologic symptoms. At the same time, miliary lung TB caused by multi-susceptible Mycobacterium tuberculosis was diagnosed. Anti-TB therapy consisting of a combination of four drugs was administered. The patient improved and was discharged five weeks later. In conclusion, TBM and multiple underling pathologies including HIV infection, as well as other risk factors can lead to a greater risk of stroke. Moreover, drug interactions and their side effects add levels of complexity. TBM must be included in the differential diagnosis of HIV infected patients with stroke and TBM treatment needs be started as soon as possible before the onset of vasculopathy.

Background and Purpose We sought to validate a previously described model combining clinical and MRI thresholds to predict outcome in acute ischemic stroke in a larger cohort, and evaluate effects of reperfusion therapy and stroke side. Materials and Methods 123 consecutive anterior circulation AIS patients underwent MRI within 6 hours of stroke onset. DWI and PWI volumes were measured. Lesion volume and NIH Stroke Scale Score thresholds were used in models predicting good three-month clinical outcome (mRS 0-2). Patients were stratified by treatment and stroke side. Results ROC analysis demonstrated 95.6% and 100% specificity for DWI > 70mL and NIH Stroke Scale Score > 20 to predict poor outcome, and 92.7% and 91.3% specificity for PWI (mean transit time) 50mL and NIH Stroke Scale Score < 8 to predict good outcome. Combining clinical and imaging thresholds led to 88.8% (71/80) positive predictive value with 65.0% (80/123) prognostic yield. 100 percent specific thresholds for DWI (103 versus 31 mL) and NIHSSS (20 versus 17) to predict poor outcome were significantly higher in treated (intravenous and/or intraarterial) versus untreated patients. Prognostic yield was lower in right versus left-sided strokes for all thresholds (10.4-20.7 vs. 16.9-40.0%). Patients with right-sided strokes had higher 100 percent specific DWI (103.1 vs. 74.8 mL) thresholds for poor outcome, and positive predictive value was lower. Conclusion Our predictive model is validated in a much larger patient cohort. Outcome may be predicted in up to two-thirds of patients, and thresholds are affected by stroke side and reperfusion therapy. PMID:25258369

There is a paucity of data regarding the association between nonalcoholic fatty liver disease (NAFLD) and acute ischemic stroke. Stroke is largely preventable, so that knowledge of risk factors is essential to achieve reductions in the stroke rate and resulting disease burden. The aim of the present study was to evaluate the prognostic value of NAFLD on stroke severity and outcome. We prospectively studied 200 patients who were admitted with acute ischemic stroke between September 2013 and August 2015. Demographic and vascular risk factors were detailed for all subjects. The severity of stroke was assessed with National Institutes of Health Stroke Scale score at admission. NAFLD was defined as serum alanine aminotransferase and/or aspartate aminotransferase levels above the upper limit of normal in the absence of other causes of elevated aminotransferase levels. The outcome was assessed with the modified Rankin scale score at discharge. NAFLD was found in 42.5% of the study population. The prevalence of diabetes was significantly higher among patients with NAFLD than those without NAFLD (P = .001). Waist circumference was significantly higher among patients with NAFLD than those without NAFLD (P < .05). Patients with NAFLD had significantly higher glucose, Triglycerides, Low density lipoprotein, serum alanine aminotransferase and aspartate aminotransferase than those without NAFLD (P < .05 for each comparison). National Institutes of Health Stroke Scale score at admission and modified Rankin scale score at discharge were significantly higher in patients with NAFLD than those without NAFLD (P < .05 for each comparison). NAFLD was found in 42.5% of acute ischemic stroke patients. NAFLD might be associated with more severe stroke and worse outcome. Copyright © 2017 National Lipid Association.

Background: The success of randomized-controlled stroke trials is dependent on the recruitment and retention of a sufficient number of patients, but fewer than half of all trials meet their target number of patients. Methods: We performed a search and review of the literature, and conducted...... a survey and workshop among 56 European stroke trialists, to identify barriers, suggest methods to improve recruitment and retention, and make a priority list of interventions that merit further evaluation. Results: The survey and workshop identified a number of barriers to patient recruitment...... and retention, from patients’ incapacity to consent, to handicaps that prevent patients from participation in trial-specific follow-up. Methods to improve recruitment and retention may include simple interventions with individual participants, funding of research networks, and reimbursement of new treatments...
Full Text Available BACKGROUND: In Urban India, stroke accounts for 1% mortality in all hospital admissions. The pathogenic role of increased plasma fibrinogen level in causing stroke has been recently reinforced. It was therefore of interest to measure plasma fibrinogen level in patients with ischemic and hemorrhagic stroke and to compare it with lipid profile. Also to sell if fibrinogen levels increase if patient has hypertension, diabetes, smoking and alcohol intake. METHODS: The study was conducted in Victoria Hospital and Bowring & Lady Curzon Hospital attached to Bangalore medical college and Research Institute. Study included 30 patients of Ischemic stroke, 20 patients of Hemorrhagic stroke and 50 age and sex matched controls. Plasma Fibrinogen level s and lipid profile were analyzed in cases and controls. Duration of the study was 2 years. RESULTS: Most common age group in our study was 61 - 70 years. Males (62% were more than females (38%. 16 patients were Diabetics (32% and 21 were Hypertensives (42%. 40% of patients had elevated total cholesterol, 20% had elevated Triglycerides, 26% had high LDL value, 36% had Low HDL levels, 32% had high VLDL value. Mean fibrinogen levels are significantly raised in cases (411.50+111.56 mg/dl compared to controls (313.76+71.24 mg/dl. Among patients with Ischemic stroke, mean fibrinogen level was 439.63+106.93 mg/dl and in hemorrhagic stroke mean level was 370.1+105.83 mg/dl. In Correlation of levels of lipid profile with levels of fibrinogen in Ischemic stroke cases, Pearson correlation showed moderate correlation for Fibrinogen vs T chol, small correlation for Fibrinogen vs TGL, Fibrinogen vs LDL and Fibrinogen vs VLDL and negative correlation for Fibrinogen vs HDL in cases and statistically significant difference for Fibrinogen vs T chol. In Hemorrhagic stroke cases, Pearson correlation showed negative correlation for Fibrinogen vs T chol, Fibrinogen vs TGL and Fibrinogen vs HDL, and trivial correlation for Fibrinogen

This article is part of the focus theme of Methods of Information in Medicine on "Pervasive Intelligent Technologies for Health". This paper addresses the evaluation with hospital staff of an in-patient environment that supports patients, family, nursing staff and medical specialists during the recovery process of neurology patients and especially patients recovering from a stroke. We describe the methods that were used to evaluate the Adaptive Daily Rhythm Atmospheres (ADRA), Artificial Skylight (AS) and Adaptive Stimulus Dosage (ASD) concepts. The goal of this evaluation was to gather qualitative and quantitative feedback from hospital staff about the usefulness, the usability and desirability of the Adaptive Daily Rhythm Atmospheres (ADRA), Artificial Skylight (AS) and Adaptive Stimulus Dosage (ASD) concepts that were implemented as different phases of a novel healing patient room. This paper reports the effects of these concepts with regard to 1) the healing process of the patient and 2) the workflow of the staff. These results are part of a larger R&D project and provide the initial feedback in an iterative user-centered design methodology. After signing informed consents, the group of participants was taken to the laboratory environment where they were introduced to the Adaptive Healing Environment Patient Room and where they could also experience the room. Then, the participants were seated next to the patient bed so they had a similar viewing angle as the patients. The participants received a booklet with questionnaires. The items on this questionnaire addressed the influence on the healing process (i.e., the possible effect the concept/phase has on the healing process of the patient, meaning faster recovery, better sleep and enhanced well-being) and influence on the workflow (i.e., the possible effect of such a concept/phase on the working activities of the staff in the ward). We presented every concept (AS and ASD) and all the phases of ADRA. After every

Stroke is known to be associated with an increase in the risk for suicide. However, there are very few population-based studies investigating the risk of suicidal ideation and attempts in patients with stroke. The purpose of this study was to compare the risk of suicidal ideation and attempts between patients with stroke and population without stroke using nationwide survey data. Individual-level data were obtained from 228,735 participants (4560 with stroke and 224,175 without stroke) of the 2013 Korean Community Health Survey. Demographic characteristics, socioeconomic status, physical health status, and mental health status were compared between patients with stroke and population without stroke. Multivariable logistic regression was performed to investigate the independent effects of the stroke on suicidal ideation and attempts. Stroke patients had more depressive mood (12.6 %) than population without stroke (5.7 %, p suicidal ideation (24.4 %) and attempts (1.3 %) than population without stroke (9.8 and 0.4 %, respectively; both p suicidal ideation (OR 1.65, 95 % CI 1.52-1.79) and suicidal attempts (OR 1.64, 95 % CI 1.21-2.22), adjusting for demographics, socioeconomic factors, and physical health and mental health factors. We found that stroke increased the risk for suicidal ideation and attempts, independent of other factors that are known to be associated with suicidality, suggesting that stroke per se may be an independent risk factor for suicidality.

Objective: Gerstmann in 1924. observed in a few patients a concomitant impairment in discriminating their own fingers, writing by hand, distinguishing left from right and performing calculations. He claimed that this tetrad of symptoms constituted a syndromal entity, assigned it to a lesion of the dominant parietal lobe. Since than, Gerstmann`s syndrome (GS) was enigma for neuropsychologists. The aim of this study was to analyze frequency and clinical features of GS among acute stroke patients. Patients and methods: We prospectively analyzed 194 acute stroke patients (average age 65±11.06 years, male 113 (58.2%), female 81 (41.8%) hospitalized at department of Neurology, University Clinical Center tuzla, during the six mounths in 2010. For clinical assessment of agraphia, alexia and acalculia we used Minessota test for differential diagnosis of aphasia’s. Results: Among these acute stroke patients, 59 (30.40%) had alexia, agraphia and acalculia or different combinations of these disorders. two patients (3.4%) had agraphia and acalculia associated with other part of tetrad of GS: fi nger agnosia and left-right disorientation. they both where men, right handed, and cranial computed tomography scan showed ischemic lesion in the left parietal and left temporoparietal lobe. Conclusion: Gerstmann`s syndrome is rare clinical entity, and has the high value in localization and the lesion is mainly localized to angular gyrus of the dominant hemisphere. PMID:23378691
Full Text Available In addition to changes in spatio-temporal and kinematic parameters, patients with stroke exhibit fear of falling as well as fatigability during gait. These changes could compromise interpretation of data from gait analysis. The aim of this study was to determine if the gait of hemiplegic patients changes significantly over successive gait trials. Forty two stroke patients and twenty healthy subjects performed 9 gait trials during a gait analysis session. The mean and variability of spatio-temporal and kinematic joint parameters were analyzed during 3 groups of consecutive gait trials (1-3, 4-6 and 7-9. Principal component analysis was used to reduce the number of variables from the joint kinematic waveforms and to identify the parts of the gait cycle which changed during the gait analysis session. The results showed that i spontaneous gait velocity and the other spatio-temporal parameters significantly increased, and ii gait variability decreased, over the last 6 gait trials compared to the first 3, for hemiplegic patients but not healthy subjects. Principal component analysis revealed changes in the sagittal waveforms of the hip, knee and ankle for hemiplegic patients after the first 3 gait trials. These results suggest that at the beginning of the gait analysis session, stroke patients exhibited phase of adaptation,characterized by a "cautious gait" but no fatigue was observed.

Caregivers of stroke patients may adapt to changes in patient functioning over time. If adaptation occurs, then caregiver burden and health may be influenced more by worsening in patient functioning than by static levels of functioning. This study examines the relationship between patients' baseline and changes in functioning and caregivers' subjective and objective burden as well as their health. Only stroke patients who had caregivers were included in this analysis (N = 356). Stroke patients (n = 281) or their proxies (n = 75) were interviewed within 4 months of hospital discharge and patients' medical records were abstracted. The primary caregiver also was interviewed at approximately the same time as the patient or proxy (N = 356). In all but one of the 75 proxy cases, the proxy was the patient's caregiver. Binomial and ordinal logistic regression models were used. Declining patient neurological functioning predicted greater objective burden and subjective burden relating to consequences for caregivers' personal lives, but it did not predict caregiver health. The impact a patient's stroke has on a caregiver's personal life and the number of hours spent caring for the patient appear to be a function of the changes of the patient's status over time rather than a function of a "snapshot" of their functioning at baseline. If these results are confirmed, interventions to protect caregivers may be indicated for stroke patients who continue to decline after hospital discharge.

Materials and Methods: A 22-item questionnaire was administered to 201 CGs of stroke survivors. The variables tested were physical and mental health, social support, financial, and personal problems. CGs were divided into Group A (Barthel index [BI] 75 according to patient's BI, according to gender (male and female CG and relation; spouses (wife, husband, daughters, sons, daughter-in-law, grandchildren, and rest (father, mother, brother, sister, and in-laws. Data were analyzed using SPSS software version–21. Data were analyzed to determine which variables of the patient effects the CG stress. Results: Majority of the CGs (74.62% were females. 65% of CGs graded their burden as moderate to severe. 81% of CGs had left their work for caregiving. More than half of the CGs felt sleep disturbance and physical strain. Psychological instability and financial burdens were reported in 3/4th of CGs. Group A CGs faced more sleep, financial, health, and social life disturbance. Patient's bladder and bowel problems, shoulder pain, patients noncooperative attitude for medication administration, and physiotherapy were more upsetting for Group A CGs. Female CGs were subjected to more sleep disturbance, physical and psychological stress, faced more difficulty regarding the patient's bladder, bowel, personal hygiene needs, and physiotherapy. Female CGs felt less motivated in caregiving than male CGs. Wives and daughters-in-law experienced more burden. Time spent and burden perceived was more by female CGs (χ2 = 15.199, P = 0.002 than males (χ2 = 11.931, P = 0.018; wives and daughters than other relations (χ2 = 32.184, P = 0.000, (χ2 = 35.162, P = 0.019. Conclusion: Our study showed that caregiving burden was predominantly shouldered by females CGs. CGs faced physical, psychological, and socioeconomic

There is no consensus concerning the presence of spasticity or the relationship between spasticity and functioning and spasticity and health-related quality of life (HRQL) in the stable phase after stroke. The aim of the present study was to describe, 18 months after stroke, the frequency of spasticity and its association with functioning and HRQL. In a cohort of 66 consecutive patients with first-ever stroke, studied prospectively, the following parameters were assessed 18 months after stroke: spasticity, by the Modified Ashworth Scale (0-4 points with 1+ as the modification), muscle stiffness, by self-report, abnormal tendon reflexes, by physical examination, motor performance, by the Lindmark Motor Assessment Scale, mobility, by the Rivermead Mobility Index, activities of daily living, by the Barthel Index, and HRQL, by the Swedish Short Form 36 Health Survey Questionnaire (SF-36). Of 66 patients studied, 38 were hemiparetic; of these, 13 displayed spasticity, 12 had increased tendon reflexes, and 7 reported muscle stiffness 18 months after stroke. Weak (r < 0.5) to moderate (r = 0.5-0.75) correlations were seen between spasticity and functioning scores. Correlations between spasticity and HRQL were generally weak (r < 0.5). Hemiparetic patients without spasticity had significantly better functioning scores and significantly better HRQL on 1 of the 8 SF-36 health scales (physical functioning) than patients with spasticity. Few patients displayed spasticity 18 months after stroke. Spasticity might contribute to impairment of movement function and to limitation of activity, but seems to have a less pronounced effect on HRQL.

Stroke may lead to several health problems, but positive effects can be promoted by learning to perform physical therapy techniques correctly. To compare two different types of observational practice (video instructions and demonstration by a physical therapist) during the use of incentive spirometry (IS). A total of 20 patients with diagnosis of stroke and 20 healthy individuals (56±9.7 years) were allocated into two groups: one with observational practice with video instructions for the use of IS and the other with observational practice with demonstration by a physical therapist. Ten attempts for the correct use of IS were carried out and the number of errors and the magnitude of response were evaluated. The statistic used to compare the results was the three-way ANOVA test. The stroke subjects showed less precision when compared to the healthy individuals (mean difference 1.80±0.38) 95%CI [1.02-2.52], pstroke subjects showed more errors with the video instructions (mean difference 1.5±0.5, 95%CI [0.43-2.56] (p=0.08)) and therapist demonstration (mean difference 2.40±0.52, 95%CI [1.29-3.50] (p=0.00)) when compared to the healthy individuals. The stroke subjects had a worse performance in learning the use of volume-oriented incentive spirometry when compared to healthy individuals; however, there was no difference between the types of observational practice, suggesting that both may be used to encourage the use of learning IS in patients with stroke.

Our aim was to explore the independent attribution of Post-stroke depression (PSD) to caregiver burden of acute ischemic stroke patients. A cross-sectional survey was performed with 271 acute ischemic stroke patients in the Huai-He Hospital and First People's Hospital of Kaifeng City in China. PSD was assessed by Self-rating Depressive Scale, and caregiver burden was assessed by Zarit Caregiver Burden Interview. Clustered logistic regression was applied to identify the impact of PSD on caregiver burden. As results, female patients, normal muscle strength and PSD were associated with caregiver burden. PSD correlated with an independent influence of 17.2% on the risk of caregiver burden, The independent influence of PSD on caregiver burden was smaller than that of social-demographics of caregivers and clinical factors of stroke patients This study suggests that PSD may have a modest influence on caregiver burden.

The intervention group, referred to as T1 group, consisted of AIS patients receiving a new standardized nursing cooperation workflow for intravenous thrombolysis (IVT at the emergency department of Shanghai East Hospital (Shanghai, People’s Republic of China from October 2015 to March 2016. Information was collected on the following therapeutic techniques used: application or not of thrombolysis, computed tomography (CT time, and door-to-needle (DTN time. A nursing coordinator who helped patients fulfill the medical examinations and diagnosis was appointed to T1 group. In addition, a nurse was sent immediately from the stroke unit to the emergency department to aid the thrombolysis treatment.Results: The average value of the door-to-CT initiation time was 38.67±5.21 min in the T0 group, whereas it was 14.39±4.35 min in the T1 group; the average values of CT completion-to-needle time were 55.06±4.82 and 30.26±3.66 min; the average values of DTN time were 100.43±6.05 and 55.68±3.62 min, respectively; thrombolysis time was improved from 12.8% (88/689 in the T0 group to 32.5% (231/712 in the T1 group (all P<0.01. In addition, the new standardized nursing cooperation workflow decreased the National Institutes of Health Stroke Scale (NIHSS scores at 24 h (P<0

There has been limited study focusing on the functional outcomes of stroke patients' after rehabilitation, such as functional improvement and discharge destination, length of stay (LOS), and complication rate. A retrospective study was conducted on 123 consecutive patients who were admitted to The Prince Charles Hospital Rehabilitation Unit from January 2011 to December 2012 with clinically defined stroke syndromes. Functional Independence Measure (FIM) score was used to measure the functional improvement. Anemia is defined by using the World Health Organization's criteria (hemoglobin concentration in men types of stroke were all comparable in both anemic and nonanemic groups. It was found that, when selecting only the patients with ischemic stroke for comparison (103 patients), there was a significantly higher FIM score improvement (discharge FIM - admission FIM) in nonanemic group (P = .042). FIM efficiency (FIM change/LOS) was also significantly higher in the nonanemic group (P = .027). Higher percentage of patients were discharged home in nonanemic group (94.3% versus 73.3%, P = .006). In addition, higher rate of complications was found in anemic group (60% versus 39%, P = .049). Anemia appears to have a significant effect on the functional improvement and discharge outcomes for patients who had an ischemic stroke. Anemia may also increase the complication rate and affect the efficiency of stroke rehabilitation for those patients. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.
Of 231 stroke patients discharged from hospital, 34 patients (14.7%) had died when reviewed 6 months later. Of 195 survivors, 115 (58%) were independent and living in the community. The remaining 80 (42%) patients were dependent. The majority of dependent patients were in institutional care but 29 (36%) were residing in the community of whom a substantial number were not receiving physiotherapy, occupational therapy or day care. Patients who were dependent in nursing homes were less likely to have received physiotherapy (48% versus 70%) or occupational therapy (28% versus 60%) compared to disabled patients in hospital based extended nursing care. 45 patients (24%) had been re-admitted to hospital although only 48% of patients had been reviewed in hospital outpatients since discharge. 64% of patients were on anti-thrombotic treatment. This survey suggests that 6 months after hospital discharge, most stroke patients are still alive and living in the community. Many of the dependent survivors have ongoing unmet medical and rehabilitation needs.

Geriatric patients' physical disabilities, dependency on care, and possible psychological ill-being may negatively affect both the patient's quality of life and the informal caregiver burden. Focusing on this interrelationship which can be particularly prominent in geriatric patients with stroke, the objective of this study was to identify determinants of patients' quality of life and informal caregiver burden. This is a prospective, multicentre, cohort study. Data were collected in 84 geriatric home-dwelling patients with stroke three months after their rehabilitation period in skilled nursing facilities (SNFs). We assessed patients' quality of life, depressive complaints, neuropsychiatric symptoms, balance, (instrumental) activities of daily living, and informal caregiver burden. Linear regression models were constructed to study the association between the variables. For several domains, high quality of life of these geriatric patients was associated with high functional independence, less neuropsychiatric symptoms, and less depressive complaints. Informal caregiver burden was not associated with patients' quality of life, but patients' neuropsychiatric symptoms were a significant determinant of high informal caregiver burden. The presence of neuropsychiatric symptoms (more specifically depressive complaints) negatively affects the quality of life of geriatric patients. Their neuropsychiatric symptoms also affect caregiver burden. Health care professionals in SNFs can play an important role in providing the necessary psychosocial support and aftercare.

Few studies have investigated the relationships between aphasia and activities of daily living (ADLs) in stroke patients. This study was aimed firstly to determine which task within the ADLs has poorer functional recovery in stroke patients with aphasia after rehabilitation, second to identify which specific task is related to aphasia. This is a prospective and observational study. Inpatients of our Rehabilitation Unit. The study was carried out in 219 patients with primary diagnosis of stroke with (104) and without aphasia (115). All patients underwent usual rehabilitation. Aachen Aphasia Test and Functional Independence Measure scale were used to assess severity of aphasia and ADLs, respectively. Gain in ADLs was the main outcome measure. At the end of rehabilitation patients with aphasia had lower gain in bathing, dressing upper body, dressing lower body, toileting, stair climbing, and higher gain in social interaction, problem solving, and memory with respect to patients without aphasia. However, when data were adjusted for side of hemiplegia, Fugl-Meyer score and trunk control test, patients with aphasia showed lower gain in dressing upper body (P=0.027), dressing lower body (P=0.009), lower toileting (P=0.027), and higher gain in social interaction (Paphasia was an important determinant of gain in bathing (β=0.26), dressing upper body (β=0.24), dressing lower body (β=0.22), lower toileting (β=0.22), and social interaction (β=-0.29). The current study points out that, after usual rehabilitation, the patients with aphasia show a poor gain in personal care activities and higher gain in social interaction. Knowledge of these findings: 1) can guide the rehabilitation team in selecting specific and appropriate therapies aimed to give patient with aphasia the highest possible functional independence in ADLs; 2) is useful to family members and social rehabilitation services for domiciliary management of patients with aphasia.
Full Text Available Lisa Mellon,1 Frank Doyle,1 Daniela Rohde,1 David Williams,2 Anne Hickey1 1Department of Psychology, Royal College of Surgeons in Ireland, Dublin, Ireland; 2Department of Geriatric and Stroke Medicine, Royal College of Surgeons in Ireland, Dublin, Ireland Background: Patient delay in presenting to hospital with stroke symptoms remains one of the major barriers to thrombolysis treatment, leading to its suboptimal use internationally. Educational interventions such as mass media campaigns and community initiatives aim to reduce patient delays by promoting the signs and symptoms of a stroke, but no consistent evidence exists to show that such interventions result in appropriate behavioral responses to stroke symptoms. Methods: A systematic literature search and narrative synthesis were conducted to examine whether public educational interventions were successful in the reduction of patient delay to hospital presentation with stroke symptoms. Three databases, MEDLINE, CINAHL, and PsycINFO, were searched to identify quantitative studies with measurable behavioral end points, including time to hospital presentation, thrombolysis rates, ambulance use, and emergency department (ED presentations with stroke. Results: Fifteen studies met the inclusion criteria: one randomized controlled trial, two time series analyses, three controlled before and after studies, five uncontrolled before and after studies, two retrospective observational studies, and two prospective observational studies. Studies were heterogeneous in quality; thus, meta-analysis was not feasible. Thirteen studies examined prehospital delay, with ten studies reporting a significant reduction in delay times, with a varied magnitude of effect. Eight studies examined thrombolysis rates, with only three studies reporting a statistically significant increase in thrombolysis administration. Five studies examined ambulance usage, and four reported a statistically significant increase in ambulance

Post-stroke patients with aphasia have higher levels of psychological distress. We aimed to find the relation between post-stroke aphasia and depression, anxiety and personality traits. One month after stroke, 61 consecutive patients with stroke were included in this study. Thirty post-stroke patients with aphasia and 31 patients without aphasia. We used the following scales a clinical-friendly: Aphasic test, Eysenck Personality Questionnaire, Hamilton anxiety and Beck Depression Inventory. Depression and anxiety were more prominent among patients with aphasia than stroke without aphasia. Psychosis was more prominent among post-stroke patients with aphasia. Our results may not exclusively exclude pre-morbid personality traits. Our study highlights the growing need to develop community rehabilitation services in the developing world, which address both physical and psychological morbidity. Copyright © 2014 Elsevier B.V.

In stroke code patients, multimodal imaging workup encompasses various imaging techniques, including baseline computed tomography (CT), magnetic resonance (MR) imaging, diffusion MR imaging, CT or MR perfusion studies, and CT or MR angiography, that are used to rule out bleeding, confirm arterial occlusion, establish tissue viability, and help select candidates for endovascular treatment as early as possible. Five recently published relevant clinical trials have demonstrated the efficacy of mechanical thrombectomy in proximal arterial occlusions; all these trials used different imaging techniques to select patients. Analyzing these trials and the scientific literature, we conclude that conventional CT interpreted with the Alberta Stroke Programme Computed Tomography Score (ASPECTS) and CT or MR angiography should always be used (level of evidence I, grade of recommendation A) and that CT and MR perfusion studies are useful in specific circumstances.

To determine whether isokinetic training can improve the strength of the hemiparetic knee musculature, functional mobility, and physical activity and to evaluate its effect on spasticity in long-term stroke survivors. Nonrandomized self-controlled trial. A volunteer sample of 15 community-dwelling stroke survivors of at least 6 months. A 6-week (3 days/week, 40 minutes/day) program consisting of warm-up, stretches, reciprocal knee extension and flexion isokinetic strengthening, and cool-down for the paretic limb. Peak isokinetic hamstring and quadriceps torque, quadriceps spasticity, gait velocity, timed Up and Go, timed stair climb, and the Human Activity Profile (HAP) scores were recorded at baseline, after training, and 4 weeks after training cessation (follow-up). Paretic muscle strength improved after training (p .87). Gait velocity increased after training (p .37; p > .91), although subjects perceived gains in their physical abilities at follow-up (p strengthening program for stroke survivors. The psychological benefit associated with physical activity is significant.
Full Text Available The aim of the present study was to investigate the association of APOE, MTHFR and ACE polymorphisms with stroke in the Zambian population. We analyzed 41 stroke patients and 116 control subjects all of Zambian origin for associations between the genotype of the APOE, MTHFR and ACE polymorphisms and stroke. The APOE ε2ε4 genotype showed increased risk for hemorrhagic stroke (P<0.05 and also a high risk for ischemic stroke (P=0.05. There was complete absence of the APOE ε2ε2 and the MTHFR TT genotypes in the Zambian population. The difference between cases and controls was not significant for the other genetic variants when analyzed for relationship between stroke, stroke subtype and genotype. We show that genetic variation at the APOE locus affects susceptibility to stroke. No detectable association were observed for the MTHFR and ACE genotypes and stroke in the Zambian population.

Several clinical measures and biomarkers are associated with motor recovery after stroke, but none are used to guide rehabilitation for individual patients. The objective of this study was to evaluate the implementation of upper limb predictions in stroke rehabilitation, by combining clinical measures and biomarkers using the Predict Recovery Potential (PREP) algorithm. Predictions were provided for patients in the implementation group (n=110) and withheld from the comparison group (n=82). Predictions guided rehabilitation therapy focus for patients in the implementation group. The effects of predictive information on clinical practice (length of stay, therapist confidence, therapy content, and dose) were evaluated. Clinical outcomes (upper limb function, impairment and use, independence, and quality of life) were measured 3 and 6 months poststroke. The primary clinical practice outcome was inpatient length of stay. The primary clinical outcome was Action Research Arm Test score 3 months poststroke. Length of stay was 1 week shorter for the implementation group (11 days; 95% confidence interval, 9-13 days) than the comparison group (17 days; 95% confidence interval, 14-21 days; P=0.001), controlling for upper limb impairment, age, sex, and comorbidities. Therapists were more confident (P=0.004) and modified therapy content according to predictions for the implementation group (Prehabilitation efficiency after stroke without compromising clinical outcome.

Evidence for effective improvement of the symptoms of cerebellar stroke is still limited. Here, we investigated the effects of repetitive transcranial magnetic stimulation (rTMS) applied over the injured cerebellar hemisphere in six patients with posterior circulation stroke. We applied a two-week course of cerebellar intermittent theta burst stimulation (iTBS). Before and after the iTBS treatment, paired-pulse TMS methods were used to explore: i) the functional connectivity between the cerebellar hemisphere and the contralateral primary motor cortex (M1), by means of the cerebellar brain inhibition (CBI) protocol; and ii) the intracortical circuits in the contralateral M1, by means of the short intra-cortical inhibition (SICI) and intra-cortical facilitation (ICF) protocols. Patients were also evaluated using the Modified International Cooperative Ataxia Rating Scale (MICARS). Cerebellar iTBS induced a decrease in CBI and an increase in ICF at an interstimulus interval of 15 msec. These neurophysiological changes were paralleled by a clinical improvement, shown by the MICARS posture and gait subscale scores. Cerebellar iTBS could be a promising tool to promote recovery of cerebellar stroke patients.

The aim of this study was to investigate whether anodal transcranial direct current stimulation over the left temporoparietal area improved audioverbal memory performance in stroke patients. Twelve stroke patients with audioverbal memory impairment participated in a single-masked, crossover, and sham-controlled experiment. The anodal or sham transcranial direct current stimulation was applied during the Rey Auditory Verbal Learning Test, which evaluates the ability to recall a list of 15 heard words over five trials. The number of correctly recalled words was compared between the anodal and sham conditions and the influence of transcranial direct current stimulation on serial position effect of the 15 words was also examined. The increase in the number of correctly recalled words from the first to the fifth trial was significantly greater in the anodal condition than in the sham condition (P primacy region) over the second to fifth trial trials, but not in the middle (next five words) or recency (last five words) regions. Anodal transcranial direct current stimulation over the left temporoparietal area improved audioverbal memory performance and induced the primacy effect in stroke patients.

[Purpose] The purpose of this study was to determine the effects of training using dual tasks on balance ability in stroke patients. [Subjects] Forty stroke patients were divided into a dual-task training group (N = 20) and a single task training group (N = 20) randomly. [Methods] The subjects in the single-task traing group stood in a comfortable position, faced a therapist, then threw a Swiss ball back and forth. They then performed balance training in which they raised and lowered their ankles while facing forward or moved objects from one table to another. The DTG performed dual tasks, which involved performing a task on an unstable surface using a balance pad. Both groups received training 30 min per day, five times per week, for eight weeks. [Results] The DTG showed significant increases in weight distribution rate, anterior limit of stability, posterior limit of stability, and BBS scores compared with the STG. [Conclusion] According to the results of this study, dual-task training and single-task training were effective in improving balance in stroke patients, dual task training is more effective for increasing balance ability.
Full Text Available Abstract Background Survivers of stroke or transient ischaemic attacks (TIA are at risk of new vascular events. Our objective was to study primary health care patients with stroke/TIA regarding their knowledge about risk factors for having a new event of stroke/TIA, possible associations between patient characteristics and patients' knowledge about risk factors, and patients' knowledge about their preventive treatment for stroke/TIA. Methods A questionnaire was distributed to 240 patients with stroke/TIA diagnoses, and 182 patients (76% responded. We asked 13 questions about diseases/conditions and lifestyle factors known to be risk factors and four questions regarding other diseases/conditions ("distractors". The patients were also asked whether they considered each disease/condition to be one of their own. Additional questions concerned the patients' social and functional status and their drug use. The t-test was used for continuous variables, chi-square test for categorical variables, and a regression model with variables influencing patient knowledge was created. Results Hypertension, hyperlipidemia and smoking were identified as risk factors by nearly 90% of patients, and atrial fibrillation and diabetes by less than 50%. Few patients considered the distractors as stroke/TIA risk factors (3-6%. Patients with a family history of cardiovascular disease, and patients diagnosed with carotid stenosis, atrial fibrillation or diabetes, knew these were stroke/TIA risk factors to a greater extent than patients without these conditions. Atrial fibrillation or a family history of cardiovascular disease was associated with better knowledge about risk factors, and higher age, cerebral haemorrhage and living alone with poorer knowledge. Only 56% of those taking anticoagulant drugs considered this as intended for prevention, while 48% of those taking platelet aggregation inhibitors thought this was for prevention. Conclusions Knowledge about hypertension

To establish prehospital triage in accordance with the new guidelines for endovascular therapy, we retrospectively analyzed the monitoring data of the city-wide transportation system using the Maria Prehospital Stroke Scale (MPSS), a novel prehospital stroke scale for emergency medical technicians (EMTs) to predict the likelihood of thrombolytic therapy after transportation. Kawasaki City, Japan, has six comprehensive stroke centers (CSCs) and six primary stroke centers (PSCs). In CSCs, endovascular therapy can be carried out 24 h a day, 7 days a week, but not in PSCs. There is no "drip and ship" protocol for further endovascular therapy from PSCs to CSCs. We determined the predictive value of MPSS scoring by the EMTs for the performance of endovascular therapy after transportation. There were 2031 patients (mean age, 71.1 ± 13.3 years) registered from April 2012 to March 2015. Multivariate logistic regression analysis indicated that the MPSS score and type of stroke center were independent predictors for performance of endovascular therapy. In particular, the odds ratio (OR) for endovascular therapy was significant for MPSS score 3 (OR, 2.914; 95% confidence interval (CI), 1.152-7.372; P = 0.024), MPSS score 4 (OR, 5.474; 95%CI, 2.300-13.029; P = 0.000), and MPSS score 5 (OR, 11.459; 95%CI, 4.334-30.296; P = 0.000) when MPSS score 1 was set as a reference. The diagnostic accuracy of the MPSS score evaluated by EMTs was 0.689 (95%CI, 0.627-0.751). Prehospital triage using MPSS scores evaluated by EMTs can predict the likelihood of performance of endovascular therapy after transportation, and may become a tool offering a flexible solution for designing a new transportation protocol.

Full Text Available Background. The use of complementary and alternative medicine in critical illness is increasing worldwide. This study investigates how traditional Chinese medicine (TCM is used in stroke patients. Methods. Using Taiwan National Health Insurance reimbursement claims, we compared the annual use of TCM between stroke patients and general population, identifying 15,330 patients with a new onset of stroke in 2000–2009. The sociodemographic status and medical comorbidities between stroke patients receiving TCM services and those without using the service were compared. Results. The use of TCM was higher in stroke patients than in the general population, 27.9% versus 25.4% in 2000 and 32.7% versus 27.8% in 2009, respectively, and grew consistently from 2000 to 2009. Among stroke patients, women, younger patients, white-collar employees, higher-income residents, and those living in areas with more TCM physicians were more likely to use TCM. Stroke patients using rehabilitation services were more likely to have more TCM visits (OR = 2.28, 95% CI = 1.96–2.66 and higher expenditure on TCM (OR = 2.67, 95% CI = 2.29–3.12 compared with stroke patients without rehabilitation. Conclusion. TCM is popular and well accepted in Taiwan. Patients with stroke have a higher TCM utilization rate than people without stroke.
Stroke and HIV infection are both common medical problems in the day to day clinical practice. Although data from developed countries confirm HIV infection as a risk for stroke the exact underlying mechanism is still unclear. Little data exist on the magnitude of HIV among patients with stroke in Tanzania.

To study the effects of infection on severe stroke patients in the Neurological Intensive Care Unit (NICU) and to find the related risk factors for mortality of severe stroke patients. We conducted a retrospective study including 343 patients with ischemic or hemorrhagic stroke and staying more than 2 patient-days in the NICU at Beijing Chaoyang Hospital from January 2011 to December 2015 to analyze the infection features of patients with severe stroke in the Neurological Intensive Care Unit. The mortality rate, hospital staying time, hospital costs, infection time and different infection sources were analyzed and Logistic analysis was performed to find the related risk factors for mortality of severe stroke patients. All analysis were conducted using SPSS 18.0. The mortality rate, hospital staying time and hospital costs of stroke patients between infected and uninfected patients were higher in infected patients than the uninfected patients, P<0.05, and except for the hospital staying time, mortality rate and hospital costs were both significantly higher in infected patients. Respiratory tract infection was the most common infection type at all time periods, P<0.05. However, urinary tract infection increased at 72 h after stroke compared with the infection within 72 h after stroke. Blood sugar level, mean arterial pressure, scores of APACHE II, history of stoke, history of heart diseases, infections and respiratory tract infection were significantly different in dead patients compared with the alive patients, P<0.05. Logistic multivariate regression analysis showed that except for history of heart diseases, the other six factors were all associated with mortality of stroke patients and were independent risk factors for mortality of stroke patients. Infection can significantly influence the mortality rate, hospital costs of stroke patients and is an independent risk factors for mortality of stroke patients.

To identify the main determinants of burden and perceived health status in caregivers of Brazilian stroke survivors. Cross-sectional study. Caregivers answered the Hospital Anxiety and Depression Scale (HADS), Zarit caregiver burden interview (ZCBI) and EuroQol. Patients were assessed with the National Institute of Health Stroke Scale, Barthel index (BI), modified-Rankin scale (m-RS), Mini Mental State Examination and HADS. 200 caregiver-patient dyads were assessed. Caregivers were significantly younger (42 vs. 57.7 years) and had more years of formal education (10 vs. 7.8 years); p caregivers were females, and 41% were spouses. The prevalence of anxiety disorders was significantly higher in female caregivers than in males (26.1 vs. 10.9%; p = 0.04). ZCBI mean score was 27.2, and female caregivers had significantly worse scores (28.7 vs. 22.3, p = 0.003). ZCBI mean score significantly increased (worsened) as the severity of the disease, based on m-RS, increased. ZCBI mean scores were significantly higher in wives than in other relatives (31.4 vs. 22.6; ANOVA, p caregiver's factors (female sex, depression as measured by HADS-depression) were independent predictors of caregiver's burden (r2 adjusted = 0.48; p Caregiver's mood was the most consistent factor influencing caregiver burden and perceived health in stroke caregivers.

The aim of this observational study was to review nutritional practice within an acute stroke unit (ASU) and compare practice against National Institute for Health and Clinical Excellence (NICE) guidance, National Patient Safety Agency (NPSA) guidelines, and the National Stroke Agenda. 'Observations of Care', a well recognized approach and part of the Royal College of Nursing clinical leadership programme, was undertaken along with a traditional audit to review nutritional care in the ASU. Usually undertaken by persons outside of the team to prevent bias, in this situation the bias was minimized as the auditor was new to the team. Current practice was evaluated and it was important for the team to have ownership of the assessment process. This article also reviews the prevalence of malnutrition in hospitals and the importance of nutritional assessment, the use of screening tools and types of diet that best maintain optimum outcomes. Patients who have experienced a stroke can face a range of problems that influence dietary intake. On admission, 16-31% are already malnourished.

To explore the perceptions of people with stroke-related dysarthria in relation to the management and rehabilitation of dysarthria. Qualitative semi-structured interviews. Community setting Subjects: Twenty-four people with an acquired dysarthria as a result of a stroke in the previous three years. All were living at home at the time of the interview. None exhibited a co-existing impairment (for example, aphasia, apraxia or cognitive impairment) that might have contributed to their communicative experiences. Participants described the considerable efforts they made to maximize their communicative effectiveness prior to, and during, communicative interactions. Activities described included careful articulation and vocal projection as well as more inconspicuous strategies including pre-planning interactions, focused, effortful speech and word substitution. Communication was facilitated by a range of strategies including drafting, rehearsal, manoeuvring and ongoing monitoring and repair. Self-led speech rehabilitation activities were functionally based and often undertaken regularly. Some novel reading-aloud and speaking-aloud activities were described. The quantity and nature of inconspicuous, internalized, cognitive activities people with dysarthria engage in to maximize their communicative effectiveness should be considered in evaluating the impact of dysarthria following stroke. Focusing upon externally observable characteristics alone is insufficient. Challenging, functionally relevant, patient-focused activities, materials and targets are more likely to be perceived by the patient as relevant and worthwhile and are thus more likely to ensure adherence to recommended rehabilitation activities.

Full Text Available The onset of bipolar disorder (BD secondary to a stroke event is a rare clinical entity. Although it may be related to specific regions of the brain, several other factors have been linked to its expression such as subcortical atrophy or chronic vascular burden. While precise locations and cerebral circuits involved in the bipolarity expression after stroke still need to be determined, their investigation represents an opportunity to study brain function and BD etiopathogenesis. We present a BD secondary to multiple subcortical biparietal lacunar infarctions, a lacunar infarction in left putamen and an ischemic lesion at the cerebral trunk evolving the right median portion, in a 65-year-old male patient who experienced manic, hypomanic, and depressive episodes, after 6, 10, and 16 months, respectively, of the cerebrovascular events.

A long-term goal in motor rehabilitation is that treatment is not selected on the basis of 'schools of thought', but rather, based on knowledge about efficacy and effectiveness of specific interventions for specific situations (e.g. functional syndromes). Motor dysfunction after stroke or TBI can be caused by many different functional syndromes such as paresis, ataxia, deafferentaion, visuo-perceptual deficits, or apraxia. Examples are provided showing that theory-based analysis of motor behavior makes it possible to describe 'syndrome-specific motor deficits'. Its potential implications for motor rehabilitation are that our understanding of altered motor behavior as well as specific therapeutic approaches might be promoted. A methodological prerequisite for clinical trials in rehabilitation is knowledge about test properties of assessment tools in follow-up situations such as test-retest reliability and responsiveness to change. Test-retest reliability assesses whether a test can produce stable measures with test repetition, while sensitivity to change reflects whether a test detects changes that occur over time. Exemplifying these considerations, a reliability and validity study of a kinematic arm movement analysis is summarized. In terms of new therapeutic developments, two examples of clinical therapeutic studies are provided assessing the efficacy of specific inter-ventions for specific situations in arm and gait rehabilitation: the Arm Ability Training for high functioning hemiparetic stroke and TBI patients, and the treadmill training for non-ambulatory hemiparetic patients. In addition, a new technical development, a machine-controlled gait trainer ist introduced.

Vitamin D deficiency is common across all age groups and may contribute to cardiovascular diseases. Serum 25-hydroxyvitamin D deficiency causing ischemic stroke has been documented in recent reports. To investigate the association of serum 25-hydroxyvitamin D deficiency with ischemic stroke and subtypes. We recruited 250 consecutive ischemic stroke patients and 250 age and sex matched controls attending the Department of Neurology, at Yashoda hospital, Hyderabad, India, from January 2011 to December 2012. All ischemic stroke patients underwent stroke subtyping. We measured 25-hydroxyvitamin D by chemiluminescence test, serum calcium, phosphorus, alkaline phosphatase, and C-reactive protein (CRP) in cases and controls. Out of 250 stroke patients, 190 (76%) were men and mean age was 58.4±11.1 years (age range-26-89 years). 25-hydroxyvitamin D deficiency was observed in 122 (48.8%) stroke patients and 79 (31.6%) controls (P=0.001). Among stroke patients, serum 25-hydroxyvitamin D deficiency was found in 54.9% (50/91) of patients with large artery atherosclerosis, 54% (20/37) in cardioembolic stroke, 44.4% (20/45) in small artery diseases, 42.8% (15/35) in stroke of other determined etiology and 40.4% (17/42) in stroke of un-determined etiology. Multiple logistic regression analysis showed an independent association of 25-hydroxyvitamin D deficiency with ischemic stroke (odds ratio: 1.6; 95% CI 1.2-2.8). The association was strongest with large artery atherosclerosis (odds ratio: 2.4; 95% CI 1.6-3.5) and cardioembolic stroke (odds ratio: 2.0; 95% CI 1.0-3.2). We found that 25-hydroxyvitamin D deficiency had an independent association with ischemic stroke. The association was established in large artery arthrosclerosis and cardioembolic stroke.
Full Text Available BACKGROUND: The incidence and burden of stroke in China is increasing rapidly. However, little is known about trends in mortality during stroke hospitalization. The objectives of this study were to assess trends of in-hospital mortality among patients with stroke and explore influence factors of in-hospital death after stroke in China. METHODS: 109 grade III class A hospitals were sampled by multistage stratified cluster sampling. All patients admitted to hospitals between 2007 and 2010 with a discharge diagnosis of stroke were included. Trends in in-hospital mortality among patients with stroke were assessed. Influence factors of in-hospital death after stroke were explored using multivariable logistic regression. RESULTS: Overall stroke hospitalizations increased from 79,894 in 2007 to 85,475 in 2010, and in-hospital mortality of stroke decreased from 3.16% to 2.30% (P<0.0001. The percentage of severe patients increased while odds of mortality (2010 versus 2007 decreased regardless of stroke type: subarachnoid hemorrhage (OR 0.792, 95% CI = 0.636 to 0.987, intracerebral hemorrhage (OR 0.647, 95% CI = 0.591 to 0.708, and ischemic stroke (OR 0.588, 95% CI = 0.532 to 0.649. In multivariable analyses, older age, male, basic health insurance, multiple comorbidities and severity of disease were linked to higher odds of in-hospital mortality. CONCLUSIONS: The mortality of stroke hospitalizations decreased likely reflecting advancements in stroke care and prevention. Decreasing of mortality with increasing of severe stroke patients indicated that we should pay more attention to rehabilitation and life quality of stroke patients. Specific individual and hospital-level characteristics may be targets for facilitating further declines.

Objective To investigate the effect of virtual reality on the recovery of cognitive impairment in stroke patients. Method Twenty-eight patients (11 males and 17 females, mean age 64.2) with cognitive impairment following stroke were recruited for this study. All patients were randomly assigned to one of two groups, the virtual reality (VR) group (n=15) or the control group (n=13). The VR group received both virtual reality training and computer-based cognitive rehabilitation, whereas the control group received only computer-based cognitive rehabilitation. To measure, activity of daily living cognitive and motor functions, the following assessment tools were used: computerized neuropsychological test and the Tower of London (TOL) test for cognitive function assessment, Korean-Modified Barthel index (K-MBI) for functional status evaluation, and the motricity index (MI) for motor function assessment. All recruited patients underwent these evaluations before rehabilitation and four weeks after rehabilitation. Results The VR group showed significant improvement in the K-MMSE, visual and auditory continuous performance tests (CPT), forward digit span test (DST), forward and backward visual span tests (VST), visual and verbal learning tests, TOL, K-MBI, and MI scores, while the control group showed significant improvement in the K-MMSE, forward DST, visual and verbal learning tests, trail-making test-type A, TOL, K-MBI, and MI scores after rehabilitation. The changes in the visual CPT and backward VST in the VR group after rehabilitation were significantly higher than those in the control group. Conclusion Our findings suggest that virtual reality training combined with computer-based cognitive rehabilitation may be of additional benefit for treating cognitive impairment in stroke patients.

Low-frequency repetitive transcranial magnetic stimulation of the nonlesional hemisphere combined with occupational therapy significantly improves motor function of the affected upper limb in poststroke hemiparetic patients, but the recovery mechanism remains unclear. To investigate the recovery mechanism using functional magnetic resonance imaging. Forty-seven poststroke hemiparetic patients were hospitalized to receive 12 sessions of 40-min low-frequency repetitive transcranial magnetic stimulation over the nonlesional hemisphere and daily occupational therapy for 15 days. Motor function was evaluated with the Fugl-Meyer Assessment and Wolf Motor Function Test. The functional magnetic resonance imaging with motor tasks was performed at admission and discharge. The laterality index of activated voxel number in Brodmann areas 4 and 6 on functional magnetic resonance imaging was calculated (laterality index range of -1 to +1). Patients were divided into two groups based on functional magnetic resonance imaging findings before the intervention: group 1: patients who showed bilateral activation (n = 27); group 2: patients with unilateral activation (n = 20). Treatment resulted in improvement in Fugl-Meyer Assessment and Wolf Motor Function Test in the two groups (P functional magnetic resonance imaging indicated that our proposed treatment can induce functional cortical reorganization, leading to motor functional recovery of the affected upper limb. Especially, it seems that neural activation in the lesional hemisphere plays an important role in such recovery in poststroke hemiparetic patients. © 2013 The Authors.

Most studies regarding autonomic dysfunction in ischemic stroke are limited to heart rate and blood pressure changes during the acute phase. However, there are few data on quantitative assessment of autonomic symptoms. We sought to assess autonomic symptoms in hypertensive ischemic stroke patients. In 100 hypertensive patients (45 with symptomatic ischemic stroke (6 months after stroke onset) and 55 without stroke), we assessed autonomic symptoms using the Scale for Outcomes in Parkinson disease-Autonomic (SCOPA-AUT). The age (mean ± standard deviation) for the stroke group was 66 ± 12 and 63 ± 15 for the without stroke group (P=0.8). Orthostatic hypotension occurred in 3.6% of the stroke group and 4.4% in the group without stroke. The total SCOPA-AUT score was higher in the stroke group compared with the group without stroke (P=0.001). Domain scores for gastrointestinal (P=0.001), urinary (P=0.005) and cardiovascular (P=0.001) were higher in the stroke group. No differences were found when comparing the total SCOPA-AUT scores for stroke subtypes (P=0.168) and for lateralization (P=0.6). SCOPA AUT scores were correlated with depression scores (P=0.001) but not with stroke severity (P=0.2). Autonomic symptoms, especially, gastrointestinal, urinary and cardiovascular function, were significantly increased in hypertensive patients with minor ischemic stroke. Symptoms were associated with depression but not with the characteristic of the stroke. Copyright © 2015 Elsevier B.V. All rights reserved.

The authors present an overview of the current evidence and management recommendations for evaluation and treatment of adults with acute ischemic stroke. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators responsible for the care of acute ischemic stroke patients within the first 48 hours from stroke onset. These guidelines supersede the prior 2007 guidelines and 2009 updates. Members of the writing committee were appointed by the American Stroke Association Stroke Council's Scientific Statement Oversight Committee, representing various areas of medical expertise. Strict adherence to the American Heart Association conflict of interest policy was maintained throughout the consensus process. Panel members were assigned topics relevant to their areas of expertise, reviewed the stroke literature with emphasis on publications since the prior guidelines, and drafted recommendations in accordance with the American Heart Association Stroke Council's Level of Evidence grading algorithm. The goal of these guidelines is to limit the morbidity and mortality associated with stroke. The guidelines support the overarching concept of stroke systems of care and detail aspects of stroke care from patient recognition; emergency medical services activation, transport, and triage; through the initial hours in the emergency department and stroke unit. The guideline discusses early stroke evaluation and general medical care, as well as ischemic stroke, specific interventions such as reperfusion strategies, and general physiological optimization for cerebral resuscitation. Because many of the recommendations are based on limited data, additional research on treatment of acute ischemic stroke remains urgently needed.

To investigate whether elastin-derived peptides (EDP) are detectable in the cerebrospinal fluid (CSF) of healthy controls and of patients with acute brain ischemia and if so to assess possible trends in EDP levels in different groups of ischemic stroke patients (small-vessel disease vs. other ischemic strokes; first-ever vs. recurrent stroke). Levels of EDP were determined by ELISA in blood sera and CSF of 80 patients with acute ischemic stroke (mean age 61.5+/-10.8; age range 47-70; 22 women) and in 15 healthy age- and sex-matched controls (mean age 57.3+/-13.4; age range 50-65). The patients were divided into a group with first ever lacunar stroke (27); first ever non-lacunar ischemic stroke (27) and recurrent stroke (26). EDP were measured early (mean 7 days, range 1-15) after stroke onset. Serum EDP levels were mildly higher in recurrent strokes as compared to first ever lacunar lesion and controls. However, in the CSF the concentrations of EDP in stroke patients were strongly elevated (from 2 up to 30 times depending on subgroup) as compared with healthy subjects. The highest level of EDP in CSF and in the serum was found in recurrent strokes. Subgroup analysis revealed a trend for significantly higher EDP concentrations in CSF in lacunar and recurrent stroke as compared with non-lacunar. This study is the first application of elastin peptide measurement to human CSF and stroke patients. The increased levels of EDP were detected in CSF of patients with lacunar and recurrent strokes.

Recurrent hemodynamic and neurological changes with persisting arterial occlusions may be attributable to cerebral blood flow steal from ischemic to nonaffected brain. Transcranial Doppler monitoring with voluntary breath-holding and serial NIH Stroke Scale (NIHSS) scores were obtained in patients with acute middle cerebral artery or internal carotid artery occlusions. The steal phenomenon was detected as transient, spontaneous, or vasodilatory stimuli-induced velocity reductions in affected arteries at the time of velocity increase in normal vessels. The steal magnitude (%) was calculated as [(MFVm-MFVb)/MFVb]x100, where m=minimum and b=baseline mean flow velocities (MFV) during the 15- to 30-second period of a total 30 second of breath-holding. Six patients had steal phenomenon on transcranial Doppler (53 to 73 years, NIHSS 4 to 15 points). Steal magnitude ranged from -15.0% to -43.2%. All patients also had recurrent neurological worsening (>2 points increase in NIHSS scores) at stable blood pressure. In 3 of 5 patients receiving noninvasive ventilatory correction for snoring/sleep apnea, no further velocity or NIHSS score changes were noted. Our descriptive study suggests possibility to detect and quantify the cerebral steal phenomenon in real-time. If the steal is confirmed as the cause of neurological worsening, reversed Robin Hood syndrome may identify a target group for testing blood pressure augmentation and noninvasive ventilatory correction in stroke patients.

Auditory disability due to impaired auditory processing (AP) despite normal pure-tone thresholds is common after stroke, and it leads to isolation, reduced quality of life and physical decline. There are currently no proven remedial interventions for AP deficits in stroke patients. This is the first study to investigate the benefits of personal frequency-modulated (FM) systems in stroke patients with disordered AP. Fifty stroke patients had baseline audiological assessments, AP tests and completed the (modified) Amsterdam Inventory for Auditory Disability and Hearing Handicap Inventory for Elderly questionnaires. Nine out of these 50 patients were diagnosed with disordered AP based on severe deficits in understanding speech in background noise but with normal pure-tone thresholds. These nine patients underwent spatial speech-in-noise testing in a sound-attenuating chamber (the "crescent of sound") with and without FM systems. The signal-to-noise ratio (SNR) for 50% correct speech recognition performance was measured with speech presented from 0° azimuth and competing babble from ±90° azimuth. Spatial release from masking (SRM) was defined as the difference between SNRs measured with co-located speech and babble and SNRs measured with spatially separated speech and babble. The SRM significantly improved when babble was spatially separated from target speech, while the patients had the FM systems in their ears compared to without the FM systems. Personal FM systems may substantially improve speech-in-noise deficits in stroke patients who are not eligible for conventional hearing aids. FMs are feasible in stroke patients and show promise to address impaired AP after stroke. Implications for Rehabilitation This is the first study to investigate the benefits of personal frequency-modulated (FM) systems in stroke patients with disordered AP. All cases significantly improved speech perception in noise with the FM systems, when noise was spatially separated from the

It has been known that stroke constitutes a major source of acquired disability, with nearly 800,000 new strokes each year in the USA alone. While advances in public and preventative health have helped reduce stroke incidence in high-income countries in recent decades, growth of the aging population, increasing stroke rates in low- to middle-income countries and medical advances that have reduced stroke mortality are all contributing to an increase in stroke survivors worldwide. Large numbers of stroke survivors have residual motor deficits. This editorial will provide an introduction to a class of new therapies being investigated with the aim of improving motor outcomes in stroke patients that uses what is known as brain-computer interface technology.
Full Text Available Abstract Background Stroke patients' care in hospital tends to be poorly organised, with poor communication and a lack of information being frequent sources of complaint. The purpose of this study was to evaluate whether a patient-held record (PHR would result in greater patient satisfaction and better care planning for stroke patients. Methods A time series control (6 months - intervention (8 months - control (6 months was used among London teaching hospital general medical and geriatric medicine inpatient wards. All stroke patients admitted to the wards during the intervention phase received a PHR and were instructed in its use. Demographic, stroke severity, social factors and outcomes were collected from all stroke patients during all phases of the study. Results Of 252 stroke patients aged 46 to 98 years entered into the study, by six months after admission 118 (46.8% had died. PHR and control group patients were well matched in terms of socio-demographic characteristics and pre-stroke ability. At six months after admission, 119 (97% patients responded to the questionnaire. Just over half (56%, 13 of intervention group patients recalled receiving a PHR. Of those patients, 59% reported reading the PHR, 27% had lost their PHR, and two-thirds said they had difficulties encouraging staff to write in the PHR. Half felt that possession of the PHR was more trouble than it was worth. PHR group patients were more satisfied with the recovery they had made (79% vs. 59%, p=0.04, but felt less able to talk to staff about their problems (61% vs. 82%, p=0.02. PHR group patients reported receiving fewer explanations about their condition (18% vs. 33%, p=0.12 and treatment (26% vs. 45%, p=0.07, and were more afraid of asking doctors questions (21% vs. 4%, p=0.01 than controls. PHR group patients were no better prepared for hospital discharge than control group patients, and both groups were ill-informed about services and benefits that might have helped

Purpose: To compare magnetic resonance imaging (MRI) brain feature in cryptogenic stroke patients with patent foramen ovale (PFO), cryptogenic stroke patients without PFO and patients with cardioembolic stroke. Materials and methods: The ethics committee required neither institutional review board approval nor informed patient consent for retrospective analyses of the patients’ medical records and imaging data. The patients’ medical files were retrospectively reviewed in accordance with human subject research protocols. Ninety-two patients under 60 years of age were included: 15 with cardioembolic stroke, 32 with cryptogenic stroke with PFO and 45 with cryptogenic stroke without PFO. Diffusion-weighted imaging of brain MRI was performed by a radiologist blinded to clinical data. Univariate, Fischer's exact test for qualitative data and non-parametric Wilcoxon test for quantitative data were used. Results: There was no statistically significant difference found between MRI features of patients with PFO and those with cardioembolic stroke (p < .05). Patients without PFO present more corticosubcortical single lesions (p < .05) than patients with PFO. Patients with PFO have more often subcortical single lesions larger than 15 mm, involvement of posterior cerebral arterial territory and intracranial occlusion (p < .05) than patients with cryptogenic stroke without PFO. Conclusion: Our study suggests a cardioembolic mechanism in ischemic stroke with PFO.

Insulin resistance was common in patients with stroke. This study investigated the association between insulin resistance and outcomes in nondiabetic patients with first-ever acute ischemic stroke. Patients with ischemic stroke without history of diabetes mellitus in the ACROSS-China registry (Abnormal Glucose Regulation in Patients With Acute Stroke Across China) were included. Insulin resistance was defined as a homeostatis model assessment-insulin resistance (HOMA-IR) index in the top quartile (Q4). HOMA-IR was calculated as fasting insulin (μU/mL)×fasting glucose (mmol/L)/22.5. Multivariable logistic regression or Cox regression was performed to estimate the association between HOMA-IR and 1-year prognosis (mortality, stroke recurrence, poor functional outcome [modified Rankin scale score 3-6], and dependence [modified Rankin scale score 3-5]). Among the 1245 patients with acute ischemic stroke enrolled in this study, the median HOMA-IR was 1.9 (interquartile range, 1.1-3.1). Patients with insulin resistance were associated with a higher mortality risk than those without (adjusted hazard ratio, 1.68; 95% confidence interval, 1.12-2.53; P =0.01), stroke recurrence (adjusted hazard ratio, 1.57, 95% confidence interval, 1.12-2.19; P =0.008), and poor outcome (adjusted odds ratio, 1.42; 95% confidence interval, 1.03-1.95; P =0.03) but not dependence after adjustment for potential confounders. Higher HOMA-IR quartile categories were associated with a higher risk of 1-year death, stroke recurrence, and poor outcome ( P for trend =0.005, 0.005, and 0.001, respectively). Insulin resistance was associated with an increased risk of death, stroke recurrence, and poor outcome but not dependence in nondiabetic patients with acute ischemic stroke. © 2017 American Heart Association, Inc.

The National Institutes of Health Stroke Scale (NIHSS) correlates with presence of large anterior vessel occlusion (LAVO). However, the application of the full NIHSS in the prehospital setting to select patients eligible for treatment with thrombectomy is limited. Therefore, we aimed to evaluate the prognostic value of simple clinical selection strategies. Data from the Safe Implementation of Thrombolysis in Stroke International Stroke Thrombolysis Registry (January 2012-May 2014) were analyzed retrospectively. Patients with complete breakdown of NIHSS scores and documented vessel status were included. We assessed the association of prehospital stroke scales and NIHSS symptom profiles with LAVO (internal carotid artery, carotid-terminus or M1-segment of the middle cerebral artery). Among 3505 patients, 23.6% (n=827) had LAVO. Pathological finding on the NIHSS item best gaze was strongly associated with LAVO (adjusted odds ratio 4.5, 95% confidence interval 3.8-5.3). All 3 face-arm-speech-time test (FAST) items identified LAVO with high sensitivity. Addition of the item gaze to the original FAST score (G-FAST) or high scores on other simplified stroke scales increased specificity. The NIHSS symptom profiles representing total anterior syndromes showed a 10-fold increased likelihood for LAVO compared with a nonspecific clinical profile. If compared with an NIHSS threshold of ≥6, the prehospital stroke scales performed similarly or even better without losing sensitivity. Simple modification of the face-arm-speech-time score or evaluating the NIHSS symptom profile may help to stratify patients' risk of LAVO and to identify individuals who deserve rapid transfer to comprehensive stroke centers. Prospective validation in the prehospital setting is required. © 2017 American Heart Association, Inc.

We evaluated the efficacy and safety of thrombus extraction using a microsnare in patients with acute ischemic stroke (AIS). This was a prospective, observational, cohort study in which consecutive patients with AIS (<6 hours of ischemia for anterior circulation and <24 hours for posterior circulation) who had been previously excluded from intravenous tissue plasminogen activator (tPA) thrombolysis were included and followed-up for 3 months. Mechanical embolectomy with a microsnare of 2-4 mm was undertaken as the first treatment. Low-dose intraarterial thrombolysis or angioplasty was used if needed. TIMI grade and modified Rankin stroke scale (mRSS) score were used to evaluate vessel recanalization and clinical efficacy, respectively. Nine patients (mean age 55 years, range 17-69 years) were included. Their basal mean NIHSS score was 16 (range 12-24). In seven out of the nine patients (77.8%) the clot was removed, giving a TIMI grade of 3 in four patients and TIMI grade 2 in three patients. Occlusion sites were: middle cerebral artery (four), basilar artery (two) and anterior cerebral artery plus middle cerebral artery (one). The mean time for recanalization from the start of the procedure was 50 min (range 50-75 min). At 3 months, the mRSS score was 0 in two patients and 3-4 in three patients (two patients died). According to our results, the microsnare is a safe procedure for mechanical thrombectomy with a good recanalization rate. Further studies are required to determine the role of the microsnare in the treatment of AIS. (orig.)

To describe stroke research activity in Australian acute public hospitals and determine if participation in research provides better quality of care and outcomes for patients with stroke. This was an observational study using data from hospitals that participated in the National Stroke Foundation (Australia) acute services audit program in 2009, 2011, and 2013. This included self-reported organizational features and a retrospective clinical audit of up to 40 medical records of patients with stroke from each hospital. Multilevel random effects logistic regression with level defined as hospital and adjustments for hospital, demographic, clinical, and stroke severity factors were undertaken. A total of 240 hospitals submitted organizational data. Hospitals with a stroke unit (70% vs 7%, p 200 stroke admissions per year (80% vs 17%, p research studies. Of 9,537 patients audited at 129 hospitals, 469 (5%) consented to participate in research. Patients who participated in research compared to nonparticipants were likely to be younger (median age 73 years; 25th percentile [Q1]: 63, 75th percentile [Q3]: 80, vs median age 76 years Q1: 64, Q3: 83; p research regardless of access to stroke unit care. Patients who participate in stroke research receive better in-hospital care and are more likely to survive compared to nonresearch participants. This study provides Class III evidence that patients with stroke who participate in research receive better quality of care and have reduced in-hospital mortality. © 2016 American Academy of Neurology.
Full Text Available Abstract Background A modified version of Postural Assessment Scale for Stroke Patients (PASS was created with some changes in the description of the items and clarifications in the manual (e.g. much help was defined as support from 2 persons. The aim of this validation study was to assess intrarater and interrater reliability using this modified version of PASS, at a stroke unit, for patients in the acute phase after their first event of stroke. Methods In the intrarater reliability study 114 patients and in the interrater reliability study 15 patients were examined twice with the test within one to 24 hours in the first week after stroke. Spearman's rank correlation, Kappa coefficients, Percentage Agreement and the newer rank-invariant methods; Relative Position, Relative Concentration and Relative rank Variance were used for the statistical analysis. Results For the intrarater reliability Spearman's rank correlations were 0.88-0.98 and k were 0.70-0.93 for the individual items. Small, statistically significant, differences were found for two items regarding Relative Position and for one item regarding Relative Concentration. There was no Relative rank Variance for any single item. For the interrater reliability, Spearman's rank correlations were 0.77-0.99 for individual items. For some items there was a possible, even if not proved, reliability problem regarding Relative Position and Relative Concentration. There was no Relative rank Variance for the single items, except for a small Relative rank Variance for one item. Conclusions The high intrarater and interrater reliability shown for the modified Postural Assessment Scale for Stroke Patients, the Swedish version of Postural Assessment Scale for Stroke Patients, with traditional and newer statistical analyses, particularly for assessments performed by the same rater, support the use of the Swedish version of Postural Assessment Scale for Stroke Patients, in the acute stage after stroke both

Methods: This prospective observational cohort study included 88 patients who have had acute ischemic stroke and a control group of 40 patients who were evaluated in the Emergency Department for disorders other than acute ischemic stroke. All subjects had RDW determined, and stroke patients had scoring with the GCS, CNS, and NIHSS scores. The GCS, CNS, and NIHSS scores of the patients were rated as mild, moderate, or severe and compared with RDW. Results: Stroke patients had significantly higher median RDW than control subjects. The median RDW values were significantly elevated in patients who had more severe rather than milder strokes rated with all three scoring systems (GCS, CNS, and NIHSS. The median RDW values were significantly elevated for patients who had moderate rather than mild strokes rated by GCS and CNS and for patients who had severe rather than mild strokes rated by NIHSS. The area under the receiver operating characteristic curve was 0.760 (95% confidence interval, 0.676–0.844. Separation of stroke patients and control groups was optimal with RDW 14% (sensitivity, 71.6%; specificity, 67.5%; accuracy, 70.3%. Conclusion: In stroke patients who have symptoms <24 hours, the RDW may be useful in predicting the severity and functional outcomes of the stroke

METHOD A cross-sectional study with 156 patients treated in a neurological clinic. Data were collected through interviews and forwarded to nurses for diagnostic inference. RESULTS 92.3% of the patients had at least one of the studied diagnoses; OUI showed the highest prevalence (72.4%, followed by FUI (53.2%, RUI (50.0%, UUI (41.0% and SUI (37.8%. Overdistended bladder and reports of inability to reach the toilet in time to avoid urine loss were the most prevalent defining characteristics. A statistically significant association of the defining characteristics with the studied diagnosis was verified. CONCLUSION The five incontinence diagnoses were identified in the evaluated patients, with different prevalence.
Full Text Available Objective To explore the relation between metabolic syndrome (MetS and cognitive impairment after ischemic stroke. Methods Ninety-four cases of first ischemic stroke patients were divided into stroke without MetS group (n = 54 and stroke with MetS group (n = 40 according to the diagnostic criteria for MetS defined by Metabolic Syndrome Researching Group of Chinese Diabetes Society. All patients underwent Mini-Mental State Examination (MMSE, Clock Drawing Test (CDT, animal Verbal Fluency Test (aVFT, Trial Making Test-A (TMT-A at 2 weeks and 3 months after stroke to evaluate mental state such as verbal learning memory, and executive, attentional and visuospatial abilities. The incidence and development of cognitive impairment were also assessed. Results At 2 weeks and 3 months after stroke, the incidence of cognitive impairment were 24.47% (23/94 and 22.34% (21/94, respectively, and in the cognitive impairment patients the incidence of non-dementia were 21.28% (20/94 and 19.15% (18/94, while the incidence of dementia were 3.19% (3/94 and 3.19% (3/94, respectively. The incidence of cognitive impairment was higher in the stroke patients with MetS than the stroke patients without MetS, 37.50% (15/40 vs 14.81% (8/54 (Z = 2.500, P = 0.012 at 2 weeks after stroke and 35.00% (14/40 vs 12.96% (7/54 (Z = 2.513, P = 0.012 at 3 months after stroke. In the scores of MMSE, delay recall and CDT of the stroke patients with MetS were all lower than those without MetS at 2 weeks after stroke and at 3 months after stroke (P < 0.05, for all. The stroke patients with MetS had more cognition deterioration than the stroke patients without MetS at 3 months after stroke, the difference was significant (Z = 2.134, P = 0.033. Conclusion MetS can increase the incidence of cognitive impairment, especially non-dementia cognitive impairment in post ischemic stroke. Executive dysfunction and hypomnesis are often seen.

Head computed tomography (CT) is critical for stroke code evaluations and often happens prior to completion of the neurological exam. Eye deviation on neuroimaging (DeyeCOM sign) has utility for predicting stroke diagnosis and correlates with National Institutes of Health Stroke Scale (NIHSS) gaze score. We further assessed the utility of the DeyeCOM sign, without complex caliper-based eye deviation calculations, but simply with a visual determination method. Patients with initial head CT and final diagnosis from an institutional review board-approved consecutive prospective registry of stroke codes at the University of California, San Diego, were included. Five stroke specialists and 1 neuroradiologist reviewed each CT. DeyeCOM+ patients were compared to DeyeCOM- patients (baseline characteristics, diagnosis, and NIHSS gaze score). Kappa statistics compared stroke specialists to neuroradiologist reads, and visual determination to caliper measurement of DeyeCOM sign. Of 181 patients, 46 were DeyeCOM+. Ischemic stroke was more commonly diagnosed in DeyeCOM+ patients compared to other diagnoses (P = .039). DeyeCOM+ patients were more likely to have an NIHSS gaze score of 1 or higher (P = .006). The NIHSS score of DeyeCOM+ stroke versus DeyeCOM- stroke patients was 8.3 ± 6.0 versus 6.7 ± 8.0 (P = .065). Functional outcomes were similar (P = .59). Stroke specialists had excellent agreement with the neuroradiologist (Κ = .89). Visual inspection had excellent agreement with the caliper method (Κ = .88). Using a time-sensitive visual determination of gaze deviation on imaging was predictive of ischemic stroke diagnosis and presence of NIHSS gaze score, and was consistent with the more complex caliper method. This study furthers the clinical utility of the DeyeCOM sign for predicting ischemic strokes. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

The purpose of this study was to evaluate the effects of mirror therapy program in addition with physical therapy methods on upper limb recovery in patients with subacute ischemic stroke. 15 subjects followed a comprehensive rehabilitative treatment, 8 subjects received only control therapy (CT) and 7 subjects received mirror therapy (MT) for 30 min every day, five times a week, for 6 weeks in addition to the conventional therapy. Brunnstrom stages, Fugl-Meyer Assessment (upper extremity), the Ashworth Scale, and Bhakta Test (finger flexion scale) were used to assess changes in upper limb motor recovery and motor function after intervention. After 6 weeks of treatment, patients in both groups showed significant improvements in the variables measured. Patients who received MT showed greater improvements compared to the CT group. The MT treatment results included: improvement of motor functions, manual skills and activities of daily living. The best results were obtained when the treatment was started soon after the stroke. MT is an easy and low-cost method to improve motor recovery of the upper limb.

The incidence of stroke is substantially higher among hemodialysis patients than among patients with earlier stages of CKD, but to what extent the initiation of dialysis accelerates the risk for stroke is not well understood. In this cohort study, we analyzed data from incident hemodialysis and peritoneal dialysis patients in 2009 who were at least 67 years old and had Medicare as primary payer. We noted whether each of the 20,979 hemodialysis patients initiated dialysis as an outpatient (47%) or inpatient (53%). One year before initiation, the baseline stroke rate was 0.15%-0.20% of patients per month (ppm) for both outpatient and inpatient initiators. Among outpatient initiators, stroke rates began rising approximately 90 days before initiation, reached 0.5% ppm during the 30 days before initiation, and peaked at 0.7% ppm (8.4% per patient-year) during the 30 days after initiation. The pattern was similar among inpatient initiators, but the stroke rate peaked at 1.5% ppm (18% per patient-year). For both hemodialysis groups, stroke rates rapidly declined by 1-2 months after initiation, fluctuated, and stabilized at approximately twice the baseline rate by 1 year. Among the 620 peritoneal dialysis patients, stroke rates were slightly lower and variable, but approximately doubled after initiation. In conclusion, these data suggest that the process of initiating dialysis may cause strokes. Further studies should evaluate methods to mitigate the risk for stroke during this high-risk period.

To provide final data on the three-year period of the inclusion of patients; to give most accurate "portrait" of patients hospitalized with a brain stroke within the framework of the LIS-2 register (Lyubertsy study of mortality in patients after stroke.Material and methods. All patients (n=960 admitted to the Lyubertsy district hospital №2 with stroke for the period from 01.2009 to 12.2011 were included into the study.Results. Men accounted for 37.5%, women - 62.5%, mean age was 71.1±9.8 years. The history of hypertension was present in 833 patients (86.8%, atrial fibrillation in 252 (26.8% patients, 199 (20.7% patients had previously undergone stroke.

Established risk factors do not fully identify patients at risk for recurrent stroke. The SPARCL trial (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) evaluated the effect of atorvastatin on stroke risk in patients with a recent stroke or transient ischemic attack and no known coronary heart disease. This analysis explored the relationships between 13 plasma biomarkers assessed at trial enrollment and the occurrence of outcome strokes. We conducted a case-cohort study of 2176 participants; 562 had outcome strokes and 1614 were selected randomly from those without outcome strokes. Time to stroke was evaluated by Cox proportional hazards models. There was no association between time to stroke and lipoprotein-associated phospholipase A 2 , monocyte chemoattractant protein-1, resistin, matrix metalloproteinase-9, N-terminal fragment of pro-B-type natriuretic peptide, soluble vascular cell adhesion molecule-1, soluble intercellular adhesion molecule-1, or soluble CD40 ligand. In adjusted analyses, osteopontin (hazard ratio per SD change, 1.362; P strokes. After adjustment for the Stroke Prognostic Instrument-II and treatment, osteopontin, neopterin, and myeloperoxidase remained independently associated with outcome strokes. The addition of these 3 biomarkers to Stroke Prognostic Instrument-II increased the area under the receiver operating characteristic curve by 0.023 ( P =0.015) and yielded a continuous net reclassification improvement (29.1%; P stroke and improved risk classification when added to a clinical risk algorithm.

Objective: We examined the accuracy of type 2 diabetes (T2D) patients' risk estimates of developing coronary heart disease (CHD)/having a stroke as a consequence of diabetes and their mood about these risks. Methods: Patients reported their perceived risks of developing CHD/having a stroke...... and rated their mood about these risks using a self-report measure. Using an objective risk calculator, they were then told their actual risk of CHD and stroke and their mood was re-assessed. Results: Patients' estimates of their risk of CHD/stroke were grossly inflated. A negative relationship between...... disease risk and mood was also seen where higher risk of actual and perceived CHD/stroke was related to worse mood. A positive relationship between mood and extent of perceptual error was further observed; the more inaccurate patients' perceptions of CHD/stroke risk were, the better their mood. Mood...

Apathy is a frequent neuropsychiatric consequence of stroke. In the under-researched population of institutionalized stroke patients, we aimed to explore the prevalence of apathy, its clinical correlates, and the relation to the amount of stimulating activities in the nursing home (NH). A cross-sectional, observational study. Dutch NHs. 274 chronic stroke patients. Data were collected through observation lists that were filled out in structured interviews with qualified nurse assistants who knew the residents well. The lists comprised the NH-version of the Apathy Evaluation Scale (AES10), the Barthel Index, the Neuropsychiatric Inventory Questionnaire, and sections of the Resident Assessment Instrument for Long-Term Care Facilities. Attending physicians and therapists provided additional information. Apathy (AES10 score ≥30) was present in 28% of residents. Multilevel regression analyses revealed that this apathy was independently related to (moderate, severe) cognitive impairment (odds ratio [OR] 11.30 [95% confidence interval (CI): 4.96-25.74], OR 5.54 [95% CI: 2.48-12.40]), very severe ADL-dependency (OR 12.10 [95% CI: 1.35-108.66]), and being >12 hours per day in bed (OR 2.10 [95% CI: 1.07-4.13]). It was not related to depressive mood symptoms (OR 1.75 [95% CI: 0.91-3.37]). Only in residents aged less than 80 years were a higher amount of activities independently related to a lower AES10 score (-0.70 [95% CI: -1.18 to -0.20] points per four extra activities in a 4-week period). Apathy is prevalent in largely one-quarter of institutionalized stroke patients, and that is most strongly related to cognitive impairment in this explorative study. We discuss the need for research on the relation with distinct dimensions of depression and fatigue as partly overlapping constructs, and on (individualized) stimulating activities as a possible intervention method.

Full Text Available Despite ample research on depression after stroke, the debate continues regarding whether symptoms such as sleep disturbances, loss of energy, changes in appetite and diminished concentration should be considered to be consequences of stroke or general symptoms of depression. By comparing symptoms in depressed and non-depressed stroke patients with patients in general practice and patients with symptomatic atherosclerotic diseases, we aim to further clarify similarities and distinctions of depression after stroke and depression in other patient populations. Based on this, it is possible to determine if somatic symptoms should be evaluated in stroke patients in diagnosing depression after stroke.An observational multicenter study is conducted in three hospitals and seven general practices including 382 stroke patients admitted to hospital with a clinical diagnosis of intracerebral hemorrhage or ischemic infarction, 1160 patients in general practice (PREDICT-NL, and 530 patients with symptomatic atherosclerotic diseases (SMART-Medea.The prevalence of major depressive disorder according to DSM-IV criteria was 14.1% (95% CI 11.0%-18.0% in the stroke cohort, 5.4% (95% CI 3.8%-7.9% in the symptomatic atherosclerotic diseases cohort and 12.9% (95% CI 11.1%-15.0% in the general practice cohorts. Comparing depressed patients of the three cohorts demonstrated broadly similar symptom profiles, as well as comparable levels of individual symptom prevalence. However, the stroke patients suffered more severely from these symptoms than patients in the other populations.The findings suggest that depression after stroke is not a different type of depression. This finding indicates that all depressive symptoms should be evaluated in stroke patients, including somatic symptoms.

The hemiplegic shoulder pain is common after a stroke. Its appearance brings pain and limits daily living activities as well as participation in specific Neuro-rehabilitation programs. All this leads to a worse functional outcome. Good management of patients can reduce both the frequency and intensity of shoulder pain, improving functional outcome. We conducted a literature search of various databases between 1980 and 2008. The articles were evaluated using the PEDro scoring system. Five evidence levels were established for the conclusions. Shoulder subluxation, occurs at an early stage after stroke and is associated with subluxation of the shoulder joint and spasticity (mainly subscapularis and pectoralis). Slings prevent subluxation of the shoulder. It is preferable to move within a lower range of motion and without aggression to prevent the occurrence of shoulder pain. The injection of corticosteroids does not improve pain and range of motion in hemiplegic patients, while botulinum toxin combined with physical therapy appears to reduce hemiplegic shoulder pain.

Full Text Available Platelets play a crucial role in the pathogenesis of stroke and antiplatelet agents exist for its treatment and prevention. Through the use of LC-MS based protein expression profiling, platelets from stroke patients were analyzed and then correlated with the proteomic analyses results in the context of this disease. This study was based on patients who post ischemic stroke were admitted to hospital and had venous blood drawn within 24 hrs of the incidence. Label-free protein expression analyses of the platelets' tryptic digest was performed in triplicate on a UPLC-ESI-qTOF-MS/MS system and ProteinLynx Global Server (v2.5, Waters was used for tandem mass data extraction. The peptide sequences were searched against the reviewed homo sapiens database (www.uniprot.org and the quantitation of protein variation was achieved through Progenesis LC-MS software (V4.0, Nonlinear Dynamics. These Label-free differential proteomics analysis of platelets ensured that 500 proteins were identified and 83 of these proteins were found to be statistically significant. The differentially expressed proteins are involved in various processes such as inflammatory response, cellular movement, immune cell trafficking, cell-to-cell signaling and interaction, hematological system development and function and nucleic acid metabolism. The expressions of myeloperoxidase, arachidonate 12-Lipoxygenase and histidine-rich glycoprotein are involved in cellular metabolic processes, crk-like protein and ras homolog gene family member A involved in cell signaling with vitronectin, thrombospondin 1, Integrin alpha 2b, and integrin beta 3 involved in cell adhesion. Apolipoprotein H, immunoglobulin heavy constant gamma 1 and immunoglobulin heavy constant gamma 3 are involved in structural, apolipoprotein A-I, and alpha-1-microglobulin/bikunin precursor is involved in transport, complement component 3 and clusterin is involved in immunity proteins as has been discussed.

The brain integrates multisensory inputs coming from the body (i.e., proprioception, tactile sensations) and the world that surrounds it (e.g., visual information). In this way, it is possible to build supra-modal and coherent mental representations of our own body, in order to process sensory events and to plan movements and actions in space. Post-stroke acquired motor deficits affect the ability to move body parts and to interact with objects. This may, in turn, impair the brain representation of the affected body part, resulting in a further increase of disability and motor impairment. To the aim of improving any putative derangements of body representation induced by the motor deficit, here we used the Mirror Box (MB). MB is a rehabilitative tool aimed at restoring several pathological conditions where body representation is affected, including post-stroke motor impairments. In this setting, observing the reflection of the intact limb in the mirror, while the affected one is hidden behind the mirror, can exert a positive influence upon different clinical conditions from chronic pain to motor deficits. Such results are thought to be mediated by a process of embodiment of the mirror reflection, which would be integrated into the representation of the affected limb. A group of 45 post-stroke patients was tested before and after performing a MB motor training in two conditions, one with the mirror between the hands and one without it, so that patients could see their impaired limb directly. A forearm bisection task, specifically designed to measure the metric representation of the body (i.e., size), was used as dependent variable. Results showed that, at baseline, the forearm bisection is shifted proximally, compatibly with a shrink of the metric representation of the affected arm towards the shoulder. However, following the MB session bisection scores shifted distally, compatibly with a partial correction of the metric representation of that arm. The effects
Full Text Available Background and Purpose. Regulatory T cells (Tregs have been suggested to modulate stroke-induced immune responses. However, analyses of Tregs in patients and in experimental stroke have yielded contradictory findings. We performed the current study to assess the regulation and function of Tregs in peripheral blood of stroke patients. Age dependent expression of CD39 on Tregs was quantified in mice and men. Methods. Total FoxP3+ Tregs and CD39+FoxP3+ Tregs were quantified by flow cytometry in controls and stroke patients on admission and on days 1, 3, 5, and 7 thereafter. Treg function was assessed by quantifying the inhibition of activation-induced expression of CD69 and CD154 on T effector cells (Teffs. Results. Total Tregs accounted for 5.0% of CD4+ T cells in controls and <2.8% in stroke patients on admission. They remained below control values until day 7. CD39+ Tregs were most strongly reduced in stroke patients. On day 3 the Treg-mediated inhibition of CD154 upregulation on CD4+ Teff was impaired in stroke patients. CD39 expression on Treg increased with age in peripheral blood of mice and men. Conclusion. We demonstrate a loss of active FoxP3+CD39+ Tregs from stroke patient’s peripheral blood. The suppressive Treg function of remaining Tregs is impaired after stroke.

Interventions are needed to improve stroke literacy among recent stroke survivors. We developed an educational video for patients hospitalized with acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH). A 5-minute stroke education video was shown to our AIS and ICH patients admitted from March to June 2015. Demographics and a 5-minute protocol Montreal Cognitive Assessment were also collected. Questions related to stroke knowledge, self-efficacy, and patient satisfaction were answered before, immediately after, and 30 days after the video. Among 250 screened, 102 patients consented, and 93 completed the video intervention. There was a significant difference between pre-video median knowledge score of 6 (IQR 4-7) and the post-video score of 7 (IQR 6-8; pvideo and the 30 day score of 7 (IQR 5-8; p = 0.04). There was a significant difference between the proportion of patients who were very certain in recognizing symptoms of a stroke pre- and post-video, which was maintained at 30-days (35.5% vs. 53.5%, p = 0.01; 35.5% vs. 54.4%, p = 0.02). The proportion who were "very satisfied" with their education post-video (74.2%) was significantly higher than pre-video (49.5%, pvideo was associated with improved stroke knowledge, self-efficacy in recognizing stroke symptoms, and satisfaction with education in hospitalized stroke patients, which was maintained at 30 days after discharge.

Antiplatelet therapy is known to decrease the risk of secondary ischemic stroke. However, the effectiveness and safety of antiplatelet therapy in patients with end-stage renal disease are uncertain, especially in dialysis. We estimated the effectiveness and safety of antiplatelet drugs (aspirin and clopidogrel) for the prevention of recurrent ischemic stroke in end-stage renal disease patients undergoing dialysis during long-term follow-up after first-time ischemic stroke. The cases were identified from the National Health Insurance Research Database. Antiplatelet therapy was administered for 11 years to patients experiencing a first ischemic stroke between 1998 and 2006. Primary outcomes, including death and readmission to hospital for stroke, and secondary outcomes, including death, stroke, and acute myocardial infarction or bleeding, were examined. In total, 1936 patients experienced a first ischemic stroke during the follow-up. In a time-dependent analysis, the hazard ratio for primary outcomes in patients treated with aspirin was 0·671 (P secondary outcomes, patients treated with aspirin, hazard ratio for readmission for stroke was 0·715 (P = 0·002) and that for bleeding was 0·885 (P = 0·291). Independent risk factors for mortality and readmission due to ischemic stroke included age, diabetes mellitus, and administration of proton pump inhibitors. Antiplatelet therapy, especially aspirin, still offers safe and effective treatment for ischemic stroke prevention in patients with end-stage renal disease undergoing dialysis. © 2014 The Authors.

The purpose of this study was to examine the effects of task-oriented electromyography-triggered stimulation for shoulder subluxation, muscle activation, pain and upper extremity function in hemiparetic stroke patients. Twenty participants with subacute hemiparetic stroke were recruited for this study and were randomly divided into two groups: experimental group (n = 10) and control group (n = 10). Subjects in the experimental group participated in task-oriented electromyography triggered stimulation for 30 minutes, five times a week for four weeks, whereas the control group received cyclic functional electrical stimulation for 30 minutes, five times a week for four weeks. Subjects in both groups received conventional physical therapy for four weeks (30 min/day, five times/week). Data collected included the degree of shoulder subluxation which had been confirmed by X-ray, muscle activation of the supraspinatus and posterior deltoid muscles by electromyography, pain by the Visual Analogue Scale (VAS), and hand function by the Fugl-Meyer Assessment (FMA) before and after the four week exercise period. The results showed significant improvement in shoulder subluxation, muscle activation, and VAS results in the experimental group, compared with the control group(p electromyography-triggered stimulation improved shoulder subluxation, muscle activation, pain and upper extremity function. These results suggest that task-oriented electromyography-triggered stimulation is effective and beneficial for individuals with subacute stroke, and that further studies should be conducted on multivarious anatomical regions.
Full Text Available Objectives: to check the consequences of poststroke dysphagia and to reflect on the nurse’s intervention in dysphagia rehabilitation. Methodology: it was performed a systematic literature review of the topic in question; research based on international databases EBSCOhost, LILACS, SciELO.We were able to identify some studies publications between 2006 and 2014. We intend to answer the guiding question: What are the consequences of dysphagia in the patient after stroke? » Results vs. Discussion: after a thorough analysis, we have selected 11 articles and found that the most frequent consequences of dysphagia are the pulmonary complications by saliva and/or food suction. The nurse specialist still has a barely visible role, but his/her interventions are critical in these patients rehabilitation. Conclusions: rehabilitation is essential to avoid the consequences of poststroke dysphagia. The rehabilitation process must go through a multidisciplinary team of which nurses are an integral and essential part.

Aim of this study was to evaluate depressive symptoms in a semi-intensive Stroke Unit (SI-SU) by a scale specifically devised to assess depression in patients with stroke and to identify the symptoms better contributing to the early detection of post stroke depression (PSD). Fifty-four patients admitted to a SI-SU because of suffering from single, first-ever hemispheric stroke were enrolled. Depressive symptoms were assessed by the Post Stroke Depression Rating Scale (PSDRS). All patients were also evaluated by the National Institute of Health Stroke Scale (NIHSS), the modified Rankin scale, the Mini-Mental State Examination (MMSE) and the Frontal Assessment Battery (FAB). The PSDRS detected depressive symptoms in twenty-two patients (40%). The PSDRS scores were not influenced by severity of stroke, functional outcome, site of lesion and type of stroke. Three psychopathological factors were identified inside the PSDRS: "reactivity", "melancholic" and "apathetic", with significant inverse correlations with cognitive measures found only with the "apathetic" factor Less than one-half items of the PSDRS were able to identify overt depressive symptoms. Depressive symptoms are a frequent and early complication in patients referred to a SI-SU with the PSDRS being a suitable tool to detect depressive symptoms in acute phases of stroke.

It has long been assumed that stroke patients plateau in their recovery within 3 to 6 months of their stroke, and evidence for rehabilitation during the chronic stage is limited. As a consequence, rehabilitation resources for the management of chronic stroke are minimal. The primary objective was to identify randomized controlled trials (RCTs) across the continuum of stroke rehabilitation for interventions initiated 6 months or more following the onset of stroke. The secondary objective was to determine whether treatments provided post 6 moths are effective in improving outcomes among stroke survivors. Multiple databases were used to identify all RCTs published from 1970 to June 2012 in English language where the stroke interventions were initiated more than 6 months after the onset of the stroke. Data abstraction was performed using standardized data abstraction form that included general citation information, study participant characteristics, methodology, outcomes accessed, and overall findings. The results of our analysis revealed 339 RCTs. The mean number of subjects per study was 73. Two hundred fifty-six RCTs were related to motor recovery, 39 to cognitive function, and only 19 to psychosocial issues and community reintegration. The majority of the RCT s demonstrated a significant positive benefit. There is a robust evidence-base for stroke rehabilitation interventions in chronic stroke. This research synthesis reveals a paradox, whereby an impressive evidence-base contrasts with the limited optimism and resources available for rehabilitation in chronic stroke.

Conclusion: Chronic stroke patients have a thicker ATFL on both the affected and unaffected sides, compared with healthy individuals. This architectural feature of the ATFL may be a result of equinovarus deformity together with spastic muscles. For this reason, early treatment of deformed ligaments and spastic muscles is needed to prevent equinovarus deformity in patients with stroke.

Hypertension is a risk factor for stroke. Increasing patient knowledge and cognition about stroke among hypertensive patients is essential. To explore the effect of a health education intervention on the knowledge and cognition of stroke in hypertensive patients. A quasi-experimental design was used with 103 patients with hypertension. The sample was recruited from a cardiologist's outpatient office at a medical center in Kaohsiung city, southern Taiwan. Half the patients (experimental group, n = 52) received health education, whereas the others received only conventional general outpatient care (control group, n = 51). All patients underwent a pretest followed by posttests at 4 and 8 weeks after the intervention. A stroke knowledge scale and stroke cognition scale were used for data collection. The experimental group scored significantly higher than the control group in level of knowledge and cognition of stroke. This study supports that a health education CD-ROM and printed information provided in the outpatient clinical improves knowledge of and cognition of stroke among hypertensive patients. In outpatient clinical practice, nurses can help improve patients' knowledge and cognition of the risks of stroke by playing the health education CD-ROM and providing printed information during the patients' wait time before appointments. Further studies with a longer follow-up (6 months or 1 year) are needed to evaluate the long-term effects of health education on stroke knowledge and cognition among patients with hypertension. An outpatient health education program using a CD-ROM and printed information for hypertensive patients can improve the patients' knowledge and cognition of stroke. © 2015 Sigma Theta Tau International.

Full Text Available India has predominantly poor rural population where brain CT scan, most often advised investigation in patients of stroke, may not always be available, hence Indian physician in such setting base his diagnosis on bed side sign evaluation for which Siriraj Stroke Score (SSS could be helpful. Objective of study: to assess the utility of SSS in patients of stroke. Methodology: sixty subjects of stroke were evaluated on SSS and 'probable' diagnosis so made was compared with CT scan's (brain 'certain' diagnosis. Main findings: by using SSS, the probable bedside diagnosis was cerebral infarct (score < -1 in 32 subjects and cerebral haemorrhage (score > +1 in 24 subjects while 4 subjects had indeterminant score (-1 to +1. Fifty subjects had their probable diagnosis matched with brain CT scan certain diagnosis. The above findings showed that SSS had 93.7% sensitivity, 76.6% specificity, 81.2% positive predictive value, 92% negative predictive value with an overall accuracy as 93.7% for diagnosis of cerebral infarction. For patients of cerebral haemorrhage the sensitivity was 83.3%, specificity was 92.5%, positive predictive value was 86.9%, negative predictive values was 92.5% with overall accuracy as 83.3%. Principal conclusion: physicians in the rural settings may find SSS to be quite useful in the management of stroke especially where more sophisticated radiological investigations may not be available for confirmation of diagnosis due to high cost or attended due to transportation risk.

Corneal confocal microscopy can identify corneal nerve damage in patients with peripheral and central neurodegeneration. However, the use of corneal confocal microscopy in patients presenting with acute ischemic stroke is unknown. One hundred thirty patients (57 without diabetes mellitus [normal glucose tolerance], 32 with impaired glucose tolerance, and 41 with type 2 diabetes mellitus) admitted with acute ischemic stroke, and 28 age-matched healthy control participants underwent corneal confocal microscopy to quantify corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length. There was a significant reduction in corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length in stroke patients with normal glucose tolerance ( P stroke.

Background: Patients with severe stroke defined as NIHSS score >17 constituting about 15-20% of cerebrovascular accident require admission into the Intensive Care Unit (ICU). However the benefit of ICU admission for stroke patients remains controversial.
Conclusions: Our results suggest that clinical management provided to elderly stroke patients by board-certificated physiatrists is associated with good functional improvement. Board certification should be encouraged to improve the quality of rehabilitative management of post-stroke patients.

'Exercise on prescription' (EoP) schemes run by fitness instructors in leisure centres in the UK have potential to promote continued rehabilitation and activity engagement post-discharge from stroke physiotherapy. This study explores the views of physiotherapists, stroke patients and fitness instructors about the appropriateness and acceptability of EoP schemes for stroke patients post-discharge from physiotherapy. This qualitative study collected data from stroke patients referred to EoP, fitness instructors and referring physiotherapists (n = 30). Data were transcribed and analysed thematically. Exploration of key themes within and between groups was made. Referral to EoP appears to alleviate some of the distress that patients and physiotherapists experience at physiotherapy discharge and provide an opportunity for physiotherapists to wean patients from physiotherapy. However, concerns about risks to patients because of fitness instructors' low levels of knowledge about stroke and the limited monitoring of exercisers were identified. Physiotherapists are likely to refer only the most able patients post-stroke to EoP. The study indicates that, in the light of limited health resources, EoP schemes have potential benefit for people post-discharge from physiotherapy. However, safety needs and the concerns of stroke survivors must be considered in EoP scheme development and management if they are to successfully help more people post-stroke maintain healthy levels of activity and fitness.

All the patients underwent neurological, neuroimaging, and neuropsychological (by the procedure described by A.R. Luria examinations. neuropsychological investigations. Anosognosia was diagnosed using the Dysexecutive Questionnaire (DEX and the authors' procedure involving a scale to measure impaired self-rating of motor abilities and a scale to measure impaired self-rating of cognitive abilities in everyday life.Results and discussion. In the acute period of hemispheric IS, reduced self-awareness of motor and cognitive abilities was noted in 14% of the patients and unawareness of only cognitive abilities was recorded in 15%. Patients with anosognosia and cognitive dysfunction (ACD and those with anosognosia and motor dysfunction (AMD had right-sided hemispheric IS more frequently (76% while this was not found in patients with isolated ACD. The development of anosognosia for paralysis and paresis was favored by the large sizes of an ischemic focus that involved a few lobes in the posterior regions of the brain although no lesions were found in the anosognosia-specific anatomical regions. ACD and AMD proved to be associated with unilateral spatial and tactile neglect and obvious regulatory dysfunction.

To verify the net effect of seizures after stroke on the use of in-hospital health care resources. Consecutive patients with first-ever stroke were admitted to the stroke unit of a Moscow hospital and followed prospectively until death or discharge. Each patient experiencing seizures was matched for age, sex, stroke type, National Institutes of Health Stroke Scale score at admission, and stroke risk factors to 2+ patients with no seizures, as controls. Resources consumed included length of hospital stay, admission to the intensive care unit (ICU), diagnostic tests, medical consultations and treatments. Cost estimates were based on the Russian National Health Service perspective. The sample comprised 30 patients with in-hospital seizures and 70 matched controls. Patients dying in hospital were 15 of 30 (50%) versus 4 of 70 (5.7%) (p stay was only slightly (nonsignificantly) higher in patients with seizures, but the cost was significantly higher in patients who died than in patients who were discharged alive. Compared to the controls, patients with seizures spent more intensive care unit (ICU) days and required more computed tomography (CT) scans, x-rays, endoscopies, and specialist consultations, causing higher in-hospital costs. In patients with first-ever stroke, seizures per se do not increase the overall in-hospital costs. However, the higher than expected mortality in patients with seizures is associated with additional hospital costs. Wiley Periodicals, Inc. © 2015 International League Against Epilepsy.

Background The objective of ischemic stroke (IS) treatment is to achieve revascularization in cerebral arteries to restore blood flow. However, there is no available method to extract arterial flow data from clinical CTA images. We developed 3D Stroke Arterial Flow Estimation (SAFE), which provides blood flow data throughout the Circle of Willis based on 3D CTA and allows comparison of arterial flow distribution in the brain. Methods We implemented a newly developed 3D vascular reconstruction algorithm for clinical stroke CTA images. Based on the patient-specific vascular structure, SAFE calculates time-resolved blood flow information for the entire Circle of Willis and allows quantitative flow study of IS cases. Clinical IS cases are presented to demonstrate the feasibility. Four patients with CTA images and CT perfusion data were studied. To validate the SAFE analysis, correlation analysis comparing blood flow at the MCA, ICA, and BA was performed. Results Different blood flow patterns were found in individual IS patients. Altered flow patterns and high collateral flow rates were found near occlusions in all cases. Quantitative comparison of blood flow data showed that SAFE obtained flow data and CTP were significantly correlated and provide complementary information about cerebral blood flow for individual patients. Conclusions We present SAFE analysis for collecting detailed time-resolved cerebral arterial flow data in the entire Circle of Willis for IS. Further study with more cases may be important to test the clinical utilization of SAFE and helpful to the study of the underlying hemodynamics of stroke.

Full Text Available Abstract Background Responsiveness data certify that a change in a measurement output represents a real change, not a measurement error or biological variability. The objective was to evaluate the responsiveness of the modified version of the Postural Assessment Scale for Stroke Patients (SwePASS in patients with a first event of stroke. An additional aim was to estimate the change in postural control during the first 12 months after stroke onset. Methods The SwePASS assessments were conducted during the first week and 3, 6 and 12 months after stroke in 90 patients. Svensson’s method, Relative Position (RP, Relative Concentration (RC and Relative Rank Variance (RV, were used to estimate the scale’s responsiveness and the patients’ change in postural control over time. Results From the first week to 3 months after stroke, the patients improved in terms of postural control with 2 to 12 times larger systematic changes in Relative Position (RP, for which 9 items and the total score showed a significant responsiveness to change when compared to the intrarater reliability measurement error of the SwePASS reported in a previous study. When SwePASS was used to assess change in postural control between the first week and 3 months, 74% of the patients received higher scores while 10% received lower scores, RP 0.31 (95% CI 0.219-0.402. The corresponding figures between 3 and 6 and between 6 and 12 months were 37% and 16%, RP 0.09 (95% CI 0.030-0.152, and 18% and 26%, RP −0.07 (95% CI −0.134- (−0.010, respectively. Conclusions The SwePASS is responsive to change. Postural control evaluated using the SwePASS showed an improvement during the first 6 months after stroke. The measurement property, in the form of responsiveness, shows that the SwePASS scoring method can be considered for use in rehabilitation when assessing postural control in patients after stroke, especially during the first 3 months.

Because stroke is among the leading causes of death, disability, hospitalizations, and healthcare expenditures in the United States, there is interest in reporting outcomes for patients hospitalized with acute ischemic stroke. The American Heart Association/American Stroke Association, as part of its commitment to promote high-quality, evidence-based care for cardiovascular and stroke patients, fully supports the development of properly risk-adjusted outcome measures for stroke. To accurately assess and report hospital-level outcomes, adequate risk adjustment for case mix is essential. During the development of the Centers for Medicare & Medicaid Services 30-day stroke mortality and 30-day stroke readmission measures, concerns were expressed that these measures were not adequately designed because they do not include a valid initial stroke severity measure, such as the National Institutes of Health Stroke Scale. These outcome measures, as currently constructed, may be prone to mischaracterizing the quality of stroke care being delivered by hospitals and may ultimately harm acute ischemic stroke patients. This article details (1) why the Centers for Medicare & Medicaid Services acute ischemic stroke outcome measures in their present form may not provide adequate risk adjustment, (2) why the measures as currently designed may lead to inaccurate representation of hospital performance and have the potential for serious unintended consequences, (3) what activities the American Heart Association/American Stroke Association has engaged in to highlight these concerns to the Centers for Medicare & Medicaid Services and other interested parties, and (4) alternative approaches and opportunities that should be considered for more accurately risk-adjusting 30-day outcomes measures in patients with ischemic stroke.

Post-stroke healthcare consumption is strongly associated with a mental health diagnosis. This study aimed to identify stroke patients who utilised mental healthcare facilities, explored their mental healthcare consumption pre-stroke and post-stroke, and examined possible predictors of costs incurred by mental healthcare consumption post-stroke. Three databases were integrated, namely the Maastricht University Medical Centre (MUMC) Medical Administration, the Stroke Registry from the Department of Neurology at MUMC, and the Psychiatric Case Registry South-Limburg. Patients from the MUMC who suffered their first-ever stroke between January 1 2000 and December 31 2004 were included and their records were analysed for mental healthcare consumption from 5 years preceding to 5 years following their stroke (1995-2009). Regression analysis was conducted to identify possible predictors of mental healthcare consumption costs. A total of 1385 patients were included and 357 (25.8%) received services from a mental healthcare facility during the 10-year reference period around their stroke. The costs of mental healthcare usage increased over time and peaked 1 year post-stroke (€7057; 22% of total mental healthcare costs). The number of hospitalisation days and mental healthcare consumption pre-stroke were significant predictors of mental healthcare costs. Explained variances of these models (costs during the 5 years post-stroke: R (2) = 15.5%, costs across a 10 year reference period: R (2) = 4.6%,) were low. Stroke patients have a significant level of mental healthcare comorbidity leading to relatively high mental healthcare costs. There is a relationship between stroke and mental healthcare consumption costs, but results concerning the underlying factors responsible for these costs are inconclusive.
Full Text Available Young stroke patients have a strong desire to return to the society, but few studies have been conducted on their rehabilitation training items, intensity, and prognosis. We analyzed clinical data of young and middle-aged/older stroke patients hospitalized in the Department of Neurological Rehabilitation, China Rehabilitation Research Center, Capital Medical University, China from February 2014 to May 2015. Results demonstrated that hemorrhagic stroke (59.6% was the primary stroke type found in the young group, while ischemic stroke (60.0% was the main type detected in the middle-aged/older group. Compared with older stroke patients, education level and incidence of hyperhomocysteinemia were higher in younger stroke patients, whereas, incidences of hypertension, diabetes, and heart disease were lower. The average length of hospital stay was longer in the young group than in the middle-aged/older group. The main risk factors observed in the young stroke patients were hypertension, drinking, smoking, hyperlipidemia, hyperhomocysteinemia, diabetes, previous history of stroke, and heart disease. The most accepted rehabilitation program consisted of physiotherapy, occupational therapy, speech therapy, acupuncture and moxibustion. Average rehabilitation training time was 2.5 hours/day. Barthel Index and modified Rankin Scale scores were increased at discharge. Six months after discharge, the degree of occupational and economic satisfaction declined, and there were no changes in family life satisfaction. The degrees of other life satisfaction (such as friendship improved. The degree of disability and functional status improved significantly in young stroke patients after professional rehabilitation, but the number of patients who returned to society within 6 months after stroke was still small.

Magnetic resonance imaging of carotid plaque can aid in stroke risk stratification in patients with carotid stenosis. However, the prevalence of complicated carotid plaque in patients with cryptogenic stroke is uncertain, especially as assessed by plaque imaging techniques routinely included in acute stroke magnetic resonance imaging protocols. We assessed whether the magnetic resonance angiography-defined presence of intraplaque high-intensity signal (IHIS), a marker of intraplaque hemorrhage, is associated with ipsilateral cryptogenic stroke. Cryptogenic stroke patients with magnetic resonance imaging evidence of unilateral anterior circulation infarction and without hemodynamically significant (≥50%) stenosis of the cervical carotid artery were identified from a prospective stroke registry at a tertiary-care hospital. High-risk plaque was assessed by evaluating for IHIS on routine magnetic resonance angiography source images using a validated technique. To compare the presence of IHIS on the ipsilateral versus contralateral side within individual patients, we used McNemar's test for correlated proportions. A total of 54 carotid arteries in 27 unique patients were included. A total of 6 patients (22.2%) had IHIS-positive nonstenosing carotid plaque ipsilateral to the side of ischemic stroke compared to 0 patients who had IHIS-positive carotid plaques contralateral to the side of stroke (P=0.01). Stroke severity measures, diagnostic evaluations, and prevalence of vascular risk factors were not different between the IHIS-positive and IHIS-negative groups. Our findings suggest that a proportion of strokes classified as cryptogenic may be mechanistically related to complicated, nonhemodynamically significant cervical carotid artery plaque that can easily be detected by routine magnetic resonance imaging/magnetic resonance angiography acute stroke protocols. © 2015 The Authors.

Background Stroke rehabilitation improves functional recovery among stroke patients. However, little is known about clinical practice in China regarding the assessment and provision of rehabilitation among patients with acute ischemic stroke. Aims We examined the frequency and determinants of an assessment for rehabilitation among acute ischemic stroke patients from the China National Stroke Registry II. Methods Data for 19,294 acute ischemic stroke patients admitted to 219 hospitals from June 2012 to January 2013 were analyzed. The multivariable logistic regression model with the generalized estimating equation method accounting for in-hospital clustering was used to identify patient and hospital factors associated with having a rehabilitation assessment during the acute hospitalization. Results Among 19,294 acute ischemic stroke patients, 11,451 (59.4%) were assessed for rehabilitation. Rates of rehabilitation assessment varied among 219 hospitals (IQR 41.4% vs 81.5%). In the multivariable analysis, factors associated with increased likelihood of a rehabilitation assessment ( p stroke, higher NIHSS on admission, receipt of a dysphagia screen, deep venous thrombosis prophylaxis, carotid vessel imaging, longer length of stay, and treatment at a hospital with a higher number of hospital beds (per 100 units). In contrast, patients with a history of atrial fibrillation and hospitals with higher number of annual stroke discharges (per 100 patients) were less likely to receive rehabilitation assessment during the acute stroke hospitalization. Conclusions Rehabilitation assessment among acute ischemic stroke patients was suboptimal in China. Rates varied considerably among hospitals and support the need to improve adherence to recommended care for stroke survivors.

Cardiac arrhythmias are frequent in acute stroke. Stroke units are widely equipped with cardiac monitoring systems. Pre-existing heart diseases and heart-brain interactions may be implicated in causing cardiac arrhythmias in acute stroke. This article analyses cardiac arrhythmias detected in patients hospitalised in a stroke unit. Prospective observational study of consecutive patients admitted to a stroke unit with cardiac monitoring. We collected clinical data from patients and the characteristics of their cardiac arrhythmias over a 1-year period (2013). Time of arrhythmia onset, associated predisposing factors, and the therapeutic decisions made after detection of arrhythmia were examined. All patients underwent continuous cardiac monitoring during no less than 48hours. Of a total of 332 patients admitted, significant cardiac arrhythmias occurred in 98 patients (29.5%) during their stay in the stroke unit. Tachyarrhythmia (ventricular tachyarrhythmias, supraventricular tachyarrhythmias, complex ventricular ectopy) was present in 90 patients (27.1%); bradyarrhythmia was present in 13 patients (3.91%). Arrhythmias were independently associated with larger size of brain lesion and older age. In 10% of the patient total, therapeutic actions were taken after detection of significant cardiac arrhythmias. Most events occurred within the first 48hours after stroke unit admission. Systematic cardiac monitoring in patients with acute stroke is useful for detecting clinically relevant cardiac arrhythmias. Incidence of arrhythmia is higher in the first 48hours after stroke unit admission. Age and lesion size were predicted appearance of arrhythmias. Detection of cardiac arrhythmias in a stroke unit has important implications for treatment. Copyright © 2014 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

OBJECTIVES—The relation betweem serum lipids and ischaemic stroke remains controversial. Studies of lipid related risk factors in cerebrovascular disease have varied greatly in their findings and also in their definition of the cerebrovascular end points. Serum lipids are thought to interact with the pathogenesis of stroke through an atherosclerosis mechanism. Stroke in young patients have been shown to be related to non-atherosclerotic causes most of the time. The aim was to d...

Background. Long-term splinting, using static orthoses to prevent contractures, is widely accepted in stroke patients with paresis of the upper limb. A number of stroke patients complain about increased pain and spasticity, which leads to the nonuse of the orthosis and a risk of developing a clenched fist. Objectives. Evaluating long-term use of static hand-wrist orthoses and experienced comfort in chronic stroke patients. Methods. Eleven stroke patients who were advised to use a static ortho...

The pronator drift test (PDT), a neurological examination, is widely used in clinics to measure motor weakness of stroke patients. The aim of this study was to develop a PDT tool with machine learning classifiers to detect stroke symptoms based on quantification of proximal arm weakness using inertial sensors and signal processing. We extracted features of drift and pronation from accelerometer signals of wearable devices on the inner wrists of 16 stroke patients and 10 healthy controls. Signal processing and feature selection approach were applied to discriminate PDT features used to classify stroke patients. A series of machine learning techniques, namely support vector machine (SVM), radial basis function network (RBFN), and random forest (RF), were implemented to discriminate stroke patients from controls with leave-one-out cross-validation. Signal processing by the PDT tool extracted a total of 12 PDT features from sensors. Feature selection abstracted the major attributes from the 12 PDT features to elucidate the dominant characteristics of proximal weakness of stroke patients using machine learning classification. Our proposed PDT classifiers had an area under the receiver operating characteristic curve (AUC) of .806 (SVM), .769 (RBFN), and .900 (RF) without feature selection, and feature selection improves the AUCs to .913 (SVM), .956 (RBFN), and .975 (RF), representing an average performance enhancement of 15.3%. Sensors and machine learning methods can reliably detect stroke signs and quantify proximal arm weakness. Our proposed solution will facilitate pervasive monitoring of stroke patients.

The purpose of the present study was to investigate the relationship between Korean language-specific dysgraphia and unilateral spatial neglect in 31 right brain stroke patients. All patients were tested for writing errors in spontaneous writing, dictation, and copying tests. The dysgraphia was classified into visuospatial omission, visuospatial destruction, syllabic tilting, stroke omission, stroke addition, and stroke tilting. Twenty-three (77.4%) of the 31 patients made dysgraphia and 18 (58.1%) demonstrated unilateral spatial neglect. The visuospatial omission was the most common dysgraphia followed by stroke addition and omission errors. The highest number of errors was made in the copying and the least was in the spontaneous writing test. Patients with unilateral spatial neglect made a significantly higher number of dysgraphia in the copying test than those without. We identified specific dysgraphia features such as a right side space omission and a vertical stroke addition in Korean right brain stroke patients. In conclusion, unilateral spatial neglect influences copy writing system of Korean language in patients with right brain stroke.

Stroke was the third leading cause of death in Taiwan in 2014. A study found that 53.61% of stroke patients suffered from dysphagia disorder during the rehabilitation phase, which may result in lung aspiration and death. The determinants of dysphagia among nationally hospitalized-rehabilitation stroke patients have not been explored comprehensively. To explore the incidence of dysphagia among hospitalized-rehabilitation stroke patients and the related determinants of dysphagia. This descriptive and correlational research design employed a convenience sample of 130 hospitalized stroke patients from rehabilitation wards at a northern regional hospital in Taiwan. A questionnaire and functional assessment were used to collect data. Instruments used included personal and clinical characteristics data questionnaire, the National Institute of Health Stroke Scale (NIHSS), Barthel Index, Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Standardization Swallowing Assessment (SSA), and Acute Stroke Dysphagia Screening (ASDS). Data analyses contained descriptive statistics and logistic regression. The incidence of stroke dysphagia was 63.8% (SSA) and 64.6% (ASDS), respectively. Age, marital status, stroke site, stroke severity (NIHSS), and cognitive status (MMSE) were identified as significant determinants of dysphagia in bivariate logistic regression, whereas stroke severity and cognitive status were identified as significant independent determinants of dysphagia in multivariate logistic regression. Two-thirds of the participant sample were affected by dysphagia, for which NIHSS and cognitive status were identified as significant determinants. Thus, nurses may conduct early screening for high risk populations based on patients' clinical characteristics in order to reduce aspiration pneumonia problems and to improve the quality of clinical care for dysphagia patients.

Inadequate health literacy is a pervasive problem with major implications for reduced health status and health disparities. Despite the role of focused education in both primary and secondary prevention of stroke, the effect of health literacy on stroke education retention has not been reported. We examined the relationship of health literacy to the retention of knowledge after recommended stroke education. This prospective cross-sectional study was conducted at an urban safety-net hospital. Study subjects were patients older than 18 admitted to the hospital stroke unit with a diagnosis of acute ischemic stroke who were able to provide informed consent to participate (N = 100). Health literacy levels were measured by using the short form of Test of Functional Health Literacy in Adults. Patient education was provided to patients at an inpatient stroke unit by using standardized protocols, in compliance with Joint Commission specifications. The education outcomes for poststroke care education, knowledge retention, was assessed for each subject. The effect of health literacy on the Stroke Patient Education Retention scores was assessed by using univariate and multivariate analyses. Of the 100 participating patients, 59% had inadequate to marginal health literacy. Stroke patients who had marginal health literacy (mean score, 7.45; standard deviation [SD], 1.9) or adequate health literacy (mean score, 7.31; SD, 1.76) had statistically higher education outcome scores than those identified as having inadequate health literacy (mean score, 5.58; SD, 2.06). Results from multivariate analysis indicated that adequate health literacy was most predictive of education outcome retention. This study demonstrated a clear relationship between health literacy and stroke education outcomes. Studies are needed to better understand the relationship of health literacy to key educational outcomes for primary or secondary prevention of stroke and to refine stroke education for literacy

Full Text Available The authors give the data available in the literature on and the results of their studies of the epidemiology, risk factors, pathogenesis, diagnosis, and treatment of poststroke cognitive impairment (PSCI. The latter occurs in 35—83% of patients; poststroke does in 6—40%. Different mechanisms of PSCI are under discussion; these are a single infarct in a strategic area of the brain; multiple focal lesion of the brain substance in restrokes; cerebral white-matter lesion as leukoaraiosis; the presence of concomitant Alzheimer’s disease (AD. The capacities for the diagnosis of concomitant AD in PSCI are analyzed. The treatment of the latter involves secondary prevention of stroke and specific therapy for cognitive, emotional-affective, and behavioral disorders. The experience with akatinol memantine used in postischemic dementia has been found to be positive.

We studied the association between age and survival after stroke. We particularly focused on deaths that could be attributed to the stroke lesion itself; that is, early death in severe stroke. A registry of all hospitalized stroke patients in Denmark included 93897 patients with information on stroke severity (Scandinavian Stroke Scale [SSS] 0-58), computed tomography, cardiovascular risk, age, sex and fatality within 1 month. Using regression models, we constructed age trajectories of 3-days, 1-week, and 1-month case-fatality rates unadjusted and adjusted for stroke severity, sex, and cardiovascular risk factors for patients with SSS Age-trajectories (SSS age of 75 years. Case-fatality rates then declined (unadjusted model) or leveled off (adjusted model) as age increased. One-week case-fatality increased to the age of 85 years. Case-fatality then leveled off (unadjusted model) or continued to rise (adjusted model) as age increased. One-month case-fatality rates increased throughout the entire lifespan. Age-trajectories (SSS ≥ 25): the leveling off phenomenon was still present for 3-days case-fatality; however, it was less pronounced. Very early stroke case-fatality rates increasing to the age of 75-85 years subsequently leveled off or even declined with increasing age. Advanced age per se should not be seen as a disadvantage in terms of surviving stroke in the very acute phase. © 2013 Japan Geriatrics Society.

Long-term morbidities can develop after traumatic brain injury (TBI). Some studies have suggested that the risk of stroke is higher after TBI, but the association between concussion and stroke remains unclear. Using a national cohort, the authors analyzed the incidence of both hemorrhagic and ischemic strokes in patients with previous concussion. A representative cohort of approximately one million people was followed up for four years. Patients with new-onset concussion were identified (n = 13,652) as the concussion group. Subsequently, the incidence rates of later stroke events in the concussion group were compared to a sex-, age- and propensity score-matched comparison group (n = 13,652). The overall incidence rate of stroke in the concussion group was higher than that of the comparison group (9.63 versus 6.52 per 1000 person-years, p concussion group than in the comparison group (crude hazard ratio 1.48, p concussion group, the cumulative incidence rates of both ischemic stroke and hemorrhagic stroke were higher than those of the comparison group (8.9% vs. 5.8% and 2.7% vs. 1.6%, respectively, both p Concussion is an independent risk factor for both ischemic and hemorrhagic strokes. Prevention and monitoring strategies of stroke are therefore suggested for patients who have experienced concussion.

[Purpose] Early admission to inpatient rehabilitation is critical for reducing post-stroke disability. Assessing admission timing and other trends in inpatient rehabilitation are essential for improving health outcomes. This study is the first to evaluate the timing of admission of stroke patients to inpatient rehabilitation in Turkey. [Subjects and Methods] We retrospectively analyzed acute stroke survivors who were admitted to the inpatient rehabilitation program in the Ministry of Health, Ankara Physical Medicine and Rehabilitation Training and Research Hospital between January 2009 and December 2010. [Results] The mean onset of inpatient rehabilitation was 9.8 ± 6.7 weeks post-stroke in the entire cohort. Occurrence of ischemic stroke and undergoing acute stroke care at a teaching hospital were most strongly associated with early admission. These results did not change after multivariate analysis. [Conclusion] Turkish stroke survivors begin inpatient rehabilitation later than patients in other countries. The type of stroke and type of hospital in which the patient undergoes acute stroke treatment affects early admission. PMID:26180347

Aortic thoracic dissection (AD) is a serious cardiovascular disease. According to the Stanford classification; type A involves the ascending aorta and type B the descending distal to the left subclavian artery. Neurological complications secondary to AD are devastating. Ischaemic stroke and hypoxic encephalopathy are early-recognised complications of type A as the arch vessels can be involved AD. Although, late ischaemic stroke had been reported in 1.4-5% of patients with type B dissection, early stroke is very unusual as it cannot be simply explained by AD anatomical pathogenesis. We report two patients who presented with type B AD complicated by early ischaemic strokes. Work-up revealed significant cardiomyopathies in both patients but with left ventricle thrombus in one. In both patients the strokes were felt to be of cardioembolic origin. 2015 BMJ Publishing Group Ltd.

Stroke in the young has not been thoroughly investigated with most previous studies based on a small number of patients from single centers. Furthermore, recent reports indicate that Fabry disease may be a significant cause for young stroke. The primary aim of our study was to determine the prevalence of Fabry disease in young stroke patients, while the secondary aim was to describe patterns of stroke in young patients.

To investigate the effects of dynamic ankle-foot orthoses (DAFOs) on functional ambulation activities, weight bearing and spatio-temporal characteristics of hemiparetic gait and to inquire whether wearing a DAFO for 3 months has a carryover effect. Fourteen chronic hemiparetic patients who could walk independently with or without a cane were the subjects of the study. Patients were assessed initially with tennis shoes and were given custom fabricated DAFOs which they wore for three months and were retested under two conditions: with tennis shoes only and with DAFOs worn in these shoes. All patients were assessed for weight bearing percentage of the affected side, cadence, step length of the involved and uninvolved sides, step width, functional reach, timed up and go, timed down stairs, timed up stairs, physiologic cost index and velocity. Comparison of initial and third month assessments with shoes only condition showed that there was no significant improvement for the measured parameters. When comparison was made at the third month while patients were wearing tennis shoes only and when they were wearing DAFO's in their shoes there was a significant difference in favour of the condition where patients were wearing DAFOs. The benefits of using DAFOs in chronic hemiparetic patients are lost when the patients are not wearing their orthoses.

The purpose of this study was to analyze the status of inpatient care for acute first-ever stroke at three general hospitals in Korea to provide basic data and useful information on the development of comprehensive and systematic rehabilitation care for stroke patients. This study conducted a retrospective complete enumeration survey of all acute first-ever stroke patients admitted to three distinct general hospitals for 2 years by reviewing medical records. Both ischemic and hemorrhagic strokes were included. Survey items included demographic data, risk factors, stroke type, state of rehabilitation treatment, discharge destination, and functional status at discharge. A total of 2159 patients were reviewed. The mean age was 61.5±14.4 years and the ratio of males to females was 1.23:1. Proportion of ischemic stroke comprised 54.9% and hemorrhagic stroke 45.1%. Early hospital mortality rate was 8.1%. Among these patients, 27.9% received rehabilitation consultation and 22.9% underwent inpatient rehabilitation treatment. The mean period from admission to rehabilitation consultation was 14.5 days. Only 12.9% of patients were transferred to a rehabilitation department and the mean period from onset to transfer was 23.4 days. Improvements in functional status were observed in the patients who had received inpatient rehabilitation treatment after acute stroke management. Our analysis revealed that a relatively small portion of patients who suffered from an acute first-ever stroke received rehabilitation consultation and inpatient rehabilitation treatment. Thus, applying standardized clinical practice guidelines for post-acute rehabilitation care is needed to provide more effective and efficient rehabilitation services to patients with stroke.

The risk of stroke in patients with short-run atrial tachyarrhythmia (AT) remains unclear. This study aimed to investigate the relationship between short-run AT and the stroke and the use of the CHA 2 DS 2 -VASc score for the risk stratification. From the registry of 24-hour Holter monitoring, 5342 subjects without known atrial fibrillation or stroke were enrolled. Short-run AT was defined as episodes of supraventricular ectopic beats stroke. Patients with short-run AT had significantly higher stroke rates compared with patients without short-run AT (11.4% versus 8.3%; P strokes per 100 person-years for patients with CHA 2 DS 2 -VASc score of 0 and 1 were 0.23 and 0.67, respectively. However, the number of them for patients with CHA 2 DS 2 -VASc score of 2, 3, 4, and ≥5 were 1.62, 1.89, 1.30, and 2.91, respectively. In patients with CHA 2 DS 2 -VASc score of 0 or 1, age (>61 years old) and burden of premature atrial contractions (>25 beats/d) independently predicted the risk of stroke. In subgroup analyses, short-run AT patients were divided into 3 groups based on their CHA 2 DS 2 -VASc scores: low score (score of 0 [men] or 1 [women]; n=324), intermediate score (score of 1 [men] or 2 [women]; n=275), and high score (score of ≥2 [men] or ≥3 [women]; n=996). When compared with low score, intermediate and high scores were independent predictors for stroke (hazard ratio, 6.165; P stroke. Therefore, the CHA 2 DS 2 -VASc score could be used for the risk stratification. Age and burden of premature atrial contractions were independent predictors for stroke in patients with CHA 2 DS 2 -VASc score of 0 or 1. © 2017 American Heart Association, Inc.

Abstract Atrial fibrillation (AF), the most common sustained arrhythmia requiring treatment worldwide, is one of the major causes of ischemic stroke. Although amiodarone is commonly used for rhythm control in AF, its relationship with stroke has rarely been addressed. We evaluated 16,091 patients who were diagnosed with AF (Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] 427.31 and 427.32) between 1998 and 2011; the date of AF diagnosis was set as the index date. Patients with a history of stroke (ICD-9-CM 430–438) who received amiodarone before the index date or during the following 30 days, or who experienced stroke within 30 days of receiving amiodarone were excluded. Finally, 7548 patients with AF were included in this study and divided into 2 groups according to whether they received amiodarone (Anatomical Therapeutic Chemical code C01BD01) during the study period. The risk of ischemic stroke in AF patients receiving amiodarone was 1.81-fold (95% confidence interval [CI] 1.52–2.16), 1.79-fold (95% CI 1.50–2.14), and 1.78-fold (95% CI 1.49–2.13) higher than in those who did not receive amiodarone, according to crude, Model 1, and Model 2 Cox proportional hazard regression models, respectively. In a demographically stratified analysis, the risk of ischemic stroke was significantly higher in patients aged Amiodarone treatment is associated with an increased risk of stroke in patients with AF, especially in those who have an initial low risk of stroke. Antiplatelet drugs and warfarin could reduce the stroke risk in AF patients receiving amiodarone. However, as the combination of digoxin and amiodarone increases the risk of stroke in these patients, the combination of these 2 drugs should be avoided. PMID:25984674

Predicting recovery from hemiparesis after stroke is important for rehabilitation. A few recent studies reported that the levels of some growth factors shortly after stroke were positively correlated with the clinical outcomes during the chronic phase. The aim of this study was to examine the relationships between the serum levels of growth factors (vascular endothelial growth factor [VEGF], insulin-like growth factor-I [IGF-I], and hepatocyte growth factor [HGF]) and improvement in hemiparesis in stroke patients who received rehabilitation in a postacute rehabilitation hospital. Subjects were 32 stroke patients (cerebral infarction: 21 and intracerebral hemorrhage [ICH]: 11). We measured serum levels of VEGF, IGF-I, and HGF and 5 items of the Stroke Impairment Assessment Set (SIAS) for hemiparesis on admission and at discharge. Age-matched healthy subjects (n=15) served as controls. Serum levels of VEGF and HGF in cerebral infarct patients on admission were higher than those in control subjects, and the serum levels of IGF-I in stroke patients were lower than those in controls. The level of HGF in ICH patients on admission was negatively correlated with gains in SIAS, and higher outliers in HGF concentration were correlated with lower gains in SIAS. Focusing on the extremely high levels of these factors may be a predictor of the low recovery from hemiparesis after stroke. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

Stroke is a major public health concern, with estimated 16 million people worldwide experiencing first-time strokes each year, a number that is expected to rise. Two-thirds of those experiencing a stroke are younger than 70 years of age. Stroke is a leading cause of disability in adults as a result of major sequelae that include spasticity, cognitive impairment, paresis, and depression. Disabling spasticity, defined as spasticity severe enough to require intervention, occurs in 4% of stroke survivors within 1 year of first-time stroke. The aim of this report is to focus instead on a discussion of patient-provider communication, and its role in post-stroke spasticity (PSS) rehabilitation within the context of patient-centered health care. A discussion based on a review of the literature, mainly since 2000. Problems within communication are identified and suggestion to enhance communication are proposed thus improving patient-centered goal setting/goal achievement for the effective management of spasticity rehabilitation. These are as follows: (i) involving family members, (ii) educating patients and family members on stroke and rehabilitation, and (iii) establishing a common definition for long-term goals. Increased communication among physicians, patients, and payers may bridge some of the gaps and increase the effectiveness of PSS rehabilitation and management. © 2013 John Wiley & Sons A/S.

Although post-stroke depression is widely recognized, less is known about depressive symptoms in the acute stage of stroke and especially in young stroke patients. We thus investigated depressive symptoms and their determinants in such a cohort. The Stroke in Young Fabry Patients study (sifap1) prospectively recruited a large multinational European cohort (n = 5,023) of patients with a cerebrovascular event aged 18-55. For assessing clinically relevant depressive symptoms (CRDS, defined by a BDI-score ≥18) the self-reporting Beck Depression Inventory (BDI) was obtained on inclusion in the study. Associations with baseline parameters, stroke severity (National Institutes of Health Stroke Scale, NIHSS), and brain MRI findings were analyzed. From the 2007 patients with BDI documentation, 202 (10.1%) had CRDS. CRDS were observed more frequently in women (12.6 vs. 8.2% in men, p stroke or TIA (n = 1,832) no significant associations between CRDS and cerebral MRI findings such as the presence of acute infarcts (68.1 vs. 65.8%, p = 0.666), old infarctions (63.4 vs. 62.1%, p = 0.725) or white matter hyper-intensities (51.6 vs. 53.7%, p = 0.520) were found. Depressive symptoms were present in 10.1% of young stroke patients in the acute phase, and were related to risk factors but not to imaging findings. © 2015 S. Karger AG, Basel.

Although proprioceptive impairment is likely to affect in a significant manner the capacity of stroke patients to recover functionality of the upper limb, clinical assessment methods in current use are rather crude, with a low level of reliability and a limited capacity to discriminate the relevant features of the deficits. In this paper we describe a new technique based on robot technology, with the goal of providing a reliable, accurate, quantitative evaluation of the position sense in peri-personal space. The proposed technique uses a bimanual, planar robot manipuladum (BdF device), whose handles are grasped by the blindfolded patient: the paretic hand is passively placed in one of 17 positions and the subject is asked to actively match the paretic hand position in space with the other hand. The position sense of the paretic arm and the corresponding deficit of space representation are characterized by means of 7 indicators: 1) positional error; 2) holding force; 3) medio/lateral shift; 4) antero/posterior shift; 5) medio/lateral skew; 6) antero/posterior skew; 7) shrink coefficient. We also show how the same experimental setup can be used for "proprioceptive training", i.e. for providing robot assistance to the paretic arm that may improve the position sense of the patient. A preliminary, feasibility test has been carried out with one patient and three controls. © 2011 IEEE

The incidence of stroke is substantially higher among hemodialysis patients than among patients with earlier stages of CKD, but to what extent the initiation of dialysis accelerates the risk for stroke is not well understood. In this cohort study, we analyzed data from incident hemodialysis and peritoneal dialysis patients in 2009 who were at least 67 years old and had Medicare as primary payer. We noted whether each of the 20,979 hemodialysis patients initiated dialysis as an outpatient (47%...

(a) To determine levels of and factors explaining partners' burden, anxiety and depressive symptoms at two months post-stroke, (b) to predict partners' burden, anxiety and depressive symptoms at one year post-stroke based on patient and partner characteristics available at two months post-stroke. Prospective cohort study. Partners of stroke patients (N=183) were included. Main outcome measures were the Caregiver Strain Index and the Hospital Anxiety and Depression Scale. Many partners experienced high burden, anxiety and depressive symptoms. At two months post-stroke, these outcomes were associated with the partner variables: age, relationship satisfaction, pro-active coping, self-efficacy, everyday social support, burden, anxiety and depressive symptoms; and the patient variables: stroke severity and depressive symptoms. Partner outcomes at one year post-stroke were mainly predicted by the level of these outcomes at two months post-stroke. Partner outcomes at two months post-stroke predict to a large degree partner outcomes at one year post-stroke.

Poststroke rehabilitation is associated with improved outcomes. Medicaid coverage of inpatient rehabilitation facility (IRF) admissions varies by state. We explored the role of state Medicaid IRF coverage on IRF utilization among patients with stroke. Working age ischemic stroke patients with Medicaid were identified from the 2010 Nationwide Inpatient Sample. Medicaid coverage of IRFs (yes versus no) was ascertained. Primary outcome was discharge to IRF (versus other discharge destinations). We fit a logistic regression model that included patient demographics, Medicaid coverage, comorbidities, length of stay, tissue-type plasminogen activator use, state Medicaid IRF coverage, and the interaction between patient Medicaid status and state Medicaid IRF coverage while accounting for hospital clustering. Medicaid did not cover IRFs in 4 (TN, TX, SC, WV) of 42 states. The impact of State Medicaid IRF coverage was limited to Medicaid stroke patients (P for interaction stroke patients in states with Medicaid IRF coverage, Medicaid stroke patients hospitalized in states without Medicaid IRF coverage were less likely to be discharged to an IRF of 11.6% (95% confidence interval, 8.5%-14.7%) versus 19.5% (95% confidence interval, 18.3%-20.8%), Pstroke patients with Medicaid. Given the increasing stroke incidence among the working age and Medicaid expansion under the Affordable Care Act, careful attention to state Medicaid policy for poststroke rehabilitation and analysis of its effects on stroke outcome disparities are warranted. © 2014 American Heart Association, Inc.

An increased risk for ischaemic stroke has been reported in young hyperthyroidism patients independent of atrial fibrillation (AF). However, whether the use of antithyroid drugs in hyperthyroidism patients can reduce the occurrence of ischaemic stroke remains unclear. A total of 36,510 newly diagnosed hyperthyroidism patients during 2003-2006 were identified from the Taiwan National Health Insurance Research database. Each patient was individually tracked for 5 years from their index date (beginning the antithyroid drugs) to identify those who suffered from new episode of ischaemic stroke. Medication possession ratio (MPR) was used to represent the antithyroid drug compliance. The association between the MPR and the risk of stroke was examined. The stroke incidence rates for hyperthyroidism patients with age hyperthyroidism patients without AF, good antithyroid drugs compliance also reduced the incidence of stroke significantly (adjusted HR, range: 1.52-1.61; p = 0.02); but not in hyperthyroidism with AF. Hyperthyroidism patients with good antithyroid drug compliance had a lower risk of ischaemic stroke than patients with poor compliance. © 2015 John Wiley & Sons Ltd.

We selected 106 hemiplegic patients with shoulder pain hospitalized after stroke from three hospitals in Nanjing, China between February 2007 and January 2012. All patients had complete clinical data sets and accounted for 45.5% of the inpatients because of stroke. Results showed that the number of patients with hemiplegic shoulder pain post stroke increased yearly, attacking mainly males 50–69 years of age. Of 106 patients, there were 60 cases (56.6%) of adhesive capsulitis, 19 (17.9%) of sh...

Contrary to common belief of clinicians that hemorrhagic stroke survivors have better functional prognoses than ischemic, recent studies show that ischemic survivors could experience similar or even better functional improvements. However, the influence of stroke subtype on gait and posture outcomes following an intervention blending conventional physiotherapy with robotic-assisted gait therapy is missing. This study compared gait and posture outcome measures between ambulatory hemorrhagic patients and ischemic patients, who received a similar 4 weeks' intervention blending a conventional bottom-up physiotherapy approach and an exoskeleton top-down robotic-assisted gait training (RAGT) approach with Lokomat. Forty adult hemiparetic stroke inpatient subjects were recruited: 20 hemorrhagic and 20 ischemic, matched by age, gender, side of hemisphere lesion, stroke severity, and locomotor impairments. Functional Ambulation Category, Postural Assessment Scale for Stroke, Tinetti Performance Oriented Mobility Assessment, 6 Minutes Walk Test, Timed Up and Go and 10-Meter Walk Test were performed before and after a 4-week long intervention. Functional gains were calculated for all tests. Hemorrhagic and ischemic subjects showed significant improvements in Functional Ambulation Category (PStroke (Pphysiotherapy and RAGT protocol. The use of intensive treatment plans blending top-down physiotherapy and bottom-up robotic approaches is promising for post-stroke rehabilitation.

Changes in muscle architecture after stroke are usually assessed by investigating inter-limb differences. As a result bilateral changes of muscle architecture might be missed. Our aim was to investigate whether bilateral architectural changes in skeletal muscle can be detected in chronic, physically active stroke patients using quantitative muscle ultrasound (QMUS). Twenty-eight patients (mean time since stroke 5.2years, median Brunnström stage 4) were recruited. QMUS images were obtained bilaterally from 2 arm and 4 leg muscles. Corrected echogenicity (muscle ultrasound grayvalue) and muscle thickness were compared to reference values obtained from healthy subjects. Correlations of muscle changes with demographic, clinical and neurophysiological characteristics were explored. Out of 6 muscles, a significant increase in mean echogenicity was found in 4 paretic and 3 non-paretic side muscles. Significant decreases in mean muscle thickness were found in 2 paretic side muscles and 1 non-paretic side muscle. Echogenicity of the medial gastrocnemius correlated moderately with walking speed (inversely) and time since stroke. This study showed that QMUS is a feasible technique to investigate architectural changes in skeletal muscles in the chronic phase of stroke and that abnormalities can be found in muscles on both the hemiparetic and non-paretic side. Intriguing data on bilateral changes in muscles of people with stroke is presented. Directions for future research are provided. Copyright © 2016 International Federation of Clinical Neurophysiology.

Acute stroke is a time-sensitive condition in which rapid diagnosis must be made in order for thrombolytic treatment to be administered. A certain proportion of patients who receive thrombolysis will be found on further evaluation to have a diagnosis other than stroke, so-called "stroke mimics." Little is known about the role of language discordance in the emergency department diagnosis of acute ischemic stroke. This is a retrospective analysis of all acute ischemic stroke patients who received IV tissue plasminogen activator (tPA) in our emergency department between July 2011 and December 2015. Baseline characteristics, patient language, and final diagnosis were compared between encounters in which the treating neurologist and patient spoke the same language (concordant cases) and encounters in which they did not (discordant cases). A total of 350 patients received IV tPA during the study period. English was the primary language for 52.6%, Spanish for 44.9%, and other languages for 2.6%; 60.3% of cases were classified as language concordant and 39.7% as discordant. We found no significant difference in the proportion of stroke mimics in the language concordant compared to discordant groups (16.6% vs 9.4%, p = 0.06). Similarly, the proportion of stroke mimics did not differ between English- and Spanish-speaking patients (15.8% vs 11.5%, p = 0.27). Language discordance was not associated with acute stroke misdiagnosis among patients treated with IV tPA. Prospective evaluation of communication during acute stroke encounters is needed to gain clarity on the role of language discordance in acute stroke misdiagnosis.

The purpose of this cross-sectional study was to determine the prevalence and potential significance of stroke symptoms among end-stage renal disease (ESRD) patients without a prior diagnosis of stroke or TIA. We enrolled 148 participants with ESRD from 5 clinics. Stroke symptoms and functional status, basic and instrumental activities of daily living (ADL, IADL), were ascertained by validated questionnaires. Cognitive function was assessed with a neurocognitive battery. Cognitive impairment was defined as a score 2 SDs below norms for age and education in 2 domains. IADL impairment was defined as needing assistance in at least 1 of 7 IADLs. Among the 126 participants without a prior stroke or TIA, 46 (36.5%) had experienced one or more stroke symptoms. After adjustment for age, sex, race, education, language, diabetes, and cardiovascular disease, participants with stroke symptoms had lower scores on tests of attention, psychomotor speed, and executive function, and more pronounced dependence in IADLs and ADLs (p ≤ 0.01 for all). After adjustment for age, sex, race, education, language, diabetes, and cardiovascular disease, participants with stroke symptoms had a higher likelihood of cognitive impairment (odds ratio [OR] 2.47, 95% confidence interval [CI] 1.03-5.92) and IADL impairment (OR 3.86, 95% CI 1.60-9.28). Stroke symptoms are common among patients with ESRD and strongly associated with impairments in cognition and functional status. These findings suggest that clinically significant stroke events may go undiagnosed in this high-risk population.

Purpose: To assess and compare the incidence of stroke and stroke subtype in pituitary adenoma patients treated with postoperative radiation therapy (RT) and surgery alone. Methods and Materials: A cohort of 462 pituitary adenoma patients treated between 1959 and 2008 at the University Medical Center Groningen in The Netherlands was studied. Radiation therapy was administered in 236 patients. The TOAST (Trial of ORG 10172 in Acute Stroke Treatment) and the Oxfordshire Community Stroke Project classification methods were used to determine causative mechanism and anatomic localization of stroke. Stroke incidences in patients treated with RT were compared with that observed after surgery alone. Risk factors for stroke incidence were studied by log–rank test, without and with stratification for other significant risk factors. In addition, the stroke incidence was compared with the incidence rate in the general Dutch population. Results: Thirteen RT patients were diagnosed with stroke, compared with 12 surgery-alone patients. The relative risk (RR) for stroke in patients treated with postoperative RT was not significantly different compared with surgery-alone patients (univariate RR 0.62, 95% confidence interval [CI] 0.28-1.35, P=.23). Stroke risk factors were coronary or peripheral artery disease (univariate and multivariate RR 10.4, 95% CI 4.7-22.8, P<.001) and hypertension (univariate RR 3.9, 95% CI 1.6-9.8, P=.002). There was no difference in TOAST and Oxfordshire classification of stroke. In this pituitary adenoma cohort 25 strokes were observed, compared with 16.91 expected (standard incidence ratio 1.48, 95% CI 1.00-1.96, P=.049). Conclusions: In pituitary adenoma patients, an increased incidence of stroke was observed compared with the general population. However, postoperative RT was not associated with an increased incidence of stroke or differences in causative mechanism or anatomic localization of stroke compared with surgery alone.

The histologic features of thrombus may differ according to the stroke subtypes. However, in acute reperfusion therapy, fibrin-specific thrombolytics are used based on the assumption that all thrombi are alike. The histologic characteristics of thrombi were compared between patients with different stroke etiologies. Between April 2010 and March 2012, we analyzed thrombi retrieved from acute stroke patients during mechanical thrombectomy. All thrombi were analyzed using component-specific stains such as Martius scarlet blue for fibrins and immunostaining with CD42b antibody for platelets. The stroke subtypes were determined based on the Trial of ORG 10172 in Acute Stroke Treatment classification. Among 36 patients, 22 were diagnosed with cardioembolism, 8 with atherothrombosis, and 6 with undetermined etiology. In arteriogenic thrombi, red blood cells were most abundant (56.9 ± 12.2%), and the platelets covered the fibrin layers or were localized at the edge or periphery of the thrombus. In cardiogenic thrombi, fibrin was most abundant (39.5 ± 13.5%), and platelets were clustered within the rich fibrin. Red blood cells proportion was greater in arteriogenic thrombi than in cardiogenic thrombi (p thrombi than in arteriogenic thrombi (p = 0.003). Of six patients with undetermined etiology, the thrombi in five showed histologic features and composition similar to that of cardiogenic thrombi. Acute thrombi showed different histologic features according to the stroke etiology. The distribution of platelets and proportion of red blood cells and fibrin were major distinguishing factors between stroke subtypes. © 2016 World Stroke Organization.

Modern therapeutics and health care improvements prolong stroke patients' survival; however, the degree of disability remains high. Stroke survivors often require caregivers, particularly in the first year after the onset of the stroke. Longitudinal assessment of and factors associated with caregiver burden (CGB) among caregivers of stroke patients has been scarcely discussed. This study aimed to define the changes in CGB in the first year of caregiving among the caregivers of stroke patients and to identify associated factors. A prospective, multi-centered observational study was conducted in nine public hospitals in Mongolia. We used the Montgomery CGB Scale for assessing CGB, and repeated the assessment after 1 year. Stroke patient characteristics were included in the analyses. Multinomial logistic regressions were conducted to analyze changes in CGB. A paired t-test analysis revealed that demand burden increased (from 12.61 to 11.50, p = 0.034), whereas stress burden decreased (from 10.69 to 11.60, p = 0.016). Although objective burden decreased, the difference was not significant. Factors associated with these changes in CGB were the caregiver's marital status, the caregiver's relationship with the patient, financial difficulties, and the patient's sex and dependency. The information on factors predicting changes in CGB in the first year of caregiving provided in this study suggests that social or financial support can assist in reducing CGB among the caregivers of post-stroke patients.

The article represents results of a theoretical work in the field of nursing education, with the topic: Verbal Patient Information through Nurses--A Case of Stroke Patients. The literature review and analysis show that there is a shortage in (stroke) patient information generally and a lack of successful concepts and strategies for the verbal (stroke) patient information through nurses in hospitals. The authors have developed a theoretical basis for health information as a nursing intervention and this represents a model of health information as a "communicational teach-and-learn process", which is of general application to all patients. The health information takes place as a separate nursing intervention within a non-public, face-to-face communication situation and in the steps-model of the nursing process. Health information is seen as a learning process for patients and nurses too. We consider learning as information production (constructivism) and information processing (cognitivism). Both processes are influenced by different factors and the illness-situation of patients, personality information content and the environment. For a successful health information output, it is necessary to take care of these aspects and this can be realized through a constructivational understanding of didactics. There is a need for an evaluation study to prove our concept of health information.

The purpose of this study is to determine if the common insurance practice of requiring precertification before a medically ready stroke patient can be discharged to a skilled nursing facility (SNF) or inpatient rehabilitation facility (IRF) causes a delay in discharge. Eliminating delays in discharge of stroke patients is important given the increasing demands for health-care efficiency after the passage of the Affordable Health Care Act. A retrospective chart review of 1007 patients who were admitted to our comprehensive stroke center with the primary diagnosis of stroke over a 12-month period was performed. Out of the patient pool, 289 patients met the inclusion criterion of a primary diagnosis of stroke that required discharge to a SNF or IRF. All 289 patients were medically cleared for discharge to a SNF or IRF by a board-certified vascular neurologist. Of the 289 patients who met the inclusion criteria, 118 required insurance precertification and 171 did not require precertification before being discharged to a SNF or IRF. All 118 patients who required precertification had private health insurance. The patients who required insurance precertification had an average delay of discharge (DOD) of 1.5 days, and those patients who did not require precertification had an average DOD of .8 days (P value insurance precertification leads to delay in discharge, increased LOS, and increased hospital costs for stroke patients.

There are few effective therapies to achieve functional recovery from motor-related disabilities affecting the upper limb after stroke. This feasibility study tested whether a powered exoskeleton driven by a brain-computer interface (BCI), using neural activity from the unaffected cortical hemisphere, could affect motor recovery in chronic hemiparetic stroke survivors. This novel system was designed and configured for a home-based setting to test the feasibility of BCI-driven neurorehabilitation in outpatient environments. Ten chronic hemiparetic stroke survivors with moderate-to-severe upper-limb motor impairment (mean Action Research Arm Test=13.4) used a powered exoskeleton that opened and closed the affected hand using spectral power from electroencephalographic signals from the unaffected hemisphere associated with imagined hand movements of the paretic limb. Patients used the system at home for 12 weeks. Motor function was evaluated before, during, and after the treatment. Across patients, our BCI-driven approach resulted in a statistically significant average increase of 6.2 points in the Action Research Arm Test. This behavioral improvement significantly correlated with improvements in BCI control. Secondary outcomes of grasp strength, Motricity Index, and the Canadian Occupational Performance Measure also significantly improved. The findings demonstrate the therapeutic potential of a BCI-driven neurorehabilitation approach using the unaffected hemisphere in this uncontrolled sample of chronic stroke survivors. They also demonstrate that BCI-driven neurorehabilitation can be effectively delivered in the home environment, thus increasing the probability of future clinical translation.
