    Full Text Available Abstract Background Chronic plantar heel pain (CPHP is a generalised term used to describe a range of undifferentiated conditions affecting the plantar heel. Plantar fasciitis is reported as the most common cause and the terms are frequently used interchangeably in the literature. Diagnostic imaging has been used by many researchers and practitioners to investigate the involvement of specific anatomical structures in CPHP. These observations help to explain the underlying pathology of the disorder, and are of benefit in forming an accurate diagnosis and targeted treatment plan. The purpose of this systematic review was to investigate the diagnostic imaging features associated with CPHP, and evaluate study findings by meta-analysis where appropriate. Methods Bibliographic databases including Medline, Embase, CINAHL, SportDiscus and The Cochrane Library were searched electronically on March 25, 2009. Eligible articles were required to report imaging findings in participants with CPHP unrelated to inflammatory arthritis, and to compare these findings with a control group. Methodological quality was evaluated by use of the Quality Index as described by Downs and Black. Meta-analysis of study data was conducted where appropriate. Results Plantar fascia thickness as measured by ultrasonography was the most widely reported imaging feature. Meta-analysis revealed that the plantar fascia of CPHP participants was 2.16 mm thicker than control participants (95% CI = 1.60 to 2.71 mm, P P = 0.01. CPHP participants were also more likely to show radiographic evidence of subcalcaneal spur than control participants (OR = 8.52, 95% CI = 4.08 to 17.77, P Conclusion This systematic review has identified 23 studies investigating the diagnostic imaging appearance of the plantar fascia and inferior calcaneum in people with CPHP. Analysis of these studies found that people with CPHP are likely to have a thickened plantar fascia with associated fluid collection, and that

    Full Text Available Abstract Background Chronic plantar heel pain (CPHP is one of the most common musculoskeletal disorders of the foot, yet its aetiology is poorly understood. The purpose of this study was to examine the association between CPHP and a number of commonly hypothesised causative factors. Methods Eighty participants with CPHP (33 males, 47 females, mean age 52.3 years, S.D. 11.7 were matched by age (± 2 years and sex to 80 control participants (33 males, 47 females, mean age 51.9 years, S.D. 11.8. The two groups were then compared on body mass index (BMI, foot posture as measured by the Foot Posture Index (FPI, ankle dorsiflexion range of motion (ROM as measured by the Dorsiflexion Lunge Test, occupational lower limb stress using the Occupational Rating Scale and calf endurance using the Standing Heel Rise Test. Results Univariate analysis demonstrated that the CPHP group had significantly greater BMI (29.8 ± 5.4 kg/m2 vs. 27.5 ± 4.9 kg/m2; P P P 2 (OR 2.9, 95% CI 1.4 – 6.1, P P Conclusion Obesity and pronated foot posture are associated with CPHP and may be risk factors for the development of the condition. Decreased ankle dorsiflexion, calf endurance and occupational lower limb stress may not play a role in CPHP.

    Heel pain is a frequent disabling symptom. Clinical diagnosis is often difficult with a large range of possible diagnoses. Lesions of the plantar fascia form an important group. We present a review describing the common lesions of the plantar fascia, including plantar fasciitis, plantar fascia rupture, plantar fibromatosis, and plantar xanthoma, and illustrate them with appropriate magnetic resonance imaging (MRI) and ultrasound imaging. We also address foreign-body reactions, enthesopathy, and diabetic fascial disease.

    We describe the design of a new cost-effective, comfortable orthotic designed to treat heel pain associated with plantar fasciitis. The heel pad is fabricated from a 4 degrees Sorbothane medial wedge with a customized insertion of low-density Plastazote. The orthotic is medium-density Plastazote reinforced with cork in the medial longitudinal arch. One pair of orthotics takes less than 1 hour to make. Pilot data were collected retrospectively to evaluate the efficacy of the orthotic for reducing pain. Ten clients at a hand and foot orthotic clinic with a mean age of 71+/-9.1 years and with unilateral or bilateral heel pain associated with plantar fasciitis were provided with customized heel pads and soft, molded orthotics at their initial visit. Pain levels were recorded with verbal and Likert-type scales. After 5 weeks of heel pad and orthotic use, all patients showed a reduction in pain, with the overall reduction being highly significant (Pheel pads and soft molded orthotics are an effective first-line treatment for the heel pain and loss of function associated with plantar fasciitis.

    Full Text Available Plantar fasciitis is a disorder caused by inflammation of the insertion point of the plantar fascia over the medial tubercle of the calcaneus. Foot orthotics are used to treat plantar fasciitis. Heel pads medialise the centre of force, whereas medial arch supporting insoles lateralise the force. We assessed the clinical results of the treatment of plantar fasciitis with silicone heel pads and medial arch-supported silicone insoles.

    Forefoot pain is common in high-heeled shoe wearers due to the high pressure caused by the center of body mass moving forward and the increased arch height with heel elevation.Sufficient arch support could reduce the high pressure over forefoot.However,too much arch support could lead to abnormal foot alignment and pain over midfoot.Little information is reported on the relationship among plantar arch height,shank curve design and plantar pressure.This study aimed at quantifying the plantar arch height changes at different heel heights and investigating the effect of shank curve on plantar pressure distribution.The plantar arch height increased to (7.6+1.3)mm at heel height of 75 mm.The Chinese standard suggests the depth of last should be 8.5 mm for heel height of 75 mm.When a shank curve with higher depth of last (11 mm) was used,the peak pressure over forefoot further decreased in midstance phase,which might ease the forefoot problems,while the peak pressure over midfoot increased but not exceeded the discomfort pressure thresholds.To achieve a more ideal pressure distribution in high-heeled shoes,a higher than expected depth of last would be suggested that would not cause discomfort over midfoot.

    Background Plantar heel pain is a common disorder of the foot for which patients seek medical treatment. The purpose of this study is to explore the relationship between duration of symptoms in plantar fasciitis patients and demographic factors, the intensity and location of pain, extent of previous treatment and self reported pain and function. Methods The charts of patients presenting with plantar heel pain between June 2008 and October 2010 were reviewed retrospectively and 182 patients with a primary diagnosis of plantar fasciitis were identified. Patients with symptoms less than 6 months were identified as acute and patients with symptoms greater than or equal to six months were defined as having chronic symptoms. Comparisons based on duration of symptoms were performed for age, gender, BMI, comorbidities, pain location and intensity, and a functional score measured by the Foot and Ankle Ability Measure (FAAM). Results The two groups were similar in age, BMI, gender, and comorbidities. Pain severity, as measured by a VAS, was not statistically significant between the two groups (6.6 and 6.2). The acute and chronic groups of patients reported similar levels of function on both the activity of daily living (62 and 65) and sports (47 and 45) subscales of the FAAM. Patients in the chronic group were more likely to have seen more providers and tried more treatment options for this condition. Conclusion As plantar fasciitis symptoms extend beyond 6 months, patients do not experience increasing pain intensity or functional limitation. No specific risk factors have been identified to indicate a risk of developing chronic symptoms. PMID:22995253

    Full Text Available Abstract Background Plantar heel pain (plantar fasciitis is a common and disabling condition, which has a detrimental impact on health-related quality of life. Despite the high prevalence of plantar heel pain, the optimal treatment for this disorder remains unclear. Consequently, an alternative therapy such as dry needling is increasingly being used as an adjunctive treatment by health practitioners. Only two trials have investigated the effectiveness of dry needling for plantar heel pain, however both trials were of a low methodological quality. This manuscript describes the design of a randomised controlled trial to evaluate the effectiveness of dry needling for plantar heel pain. Methods Eighty community-dwelling men and woman aged over 18 years with plantar heel pain (who satisfy the inclusion and exclusion criteria will be recruited. Eligible participants with plantar heel pain will be randomised to receive either one of two interventions, (i real dry needling or (ii sham dry needling. The protocol (including needling details and treatment regimen was formulated by general consensus (using the Delphi research method using 30 experts worldwide that commonly use dry needling for plantar heel pain. Primary outcome measures will be the pain subscale of the Foot Health Status Questionnaire and "first step" pain as measured on a visual analogue scale. The secondary outcome measures will be health related quality of life (assessed using the Short Form-36 questionnaire - Version Two and depression, anxiety and stress (assessed using the Depression, Anxiety and Stress Scale - short version. Primary outcome measures will be performed at baseline, 2, 4, 6 and 12 weeks and secondary outcome measures will be performed at baseline, 6 and 12 weeks.

    Full Text Available Abstract Background Plantar heel pain is a commonly occurring foot complaint. Stretching is frequently utilised as a treatment, yet a systematic review focusing only on its effectiveness has not been published. This review aimed to assess the effectiveness of stretching on pain and function in people with plantar heel pain. Methods Medline, EMBASE, CINAHL, AMED, and The Cochrane Library were searched from inception to July 2010. Studies fulfilling the inclusion criteria were independently assessed, and their quality evaluated using the modified PEDro scale. Results Six studies including 365 symptomatic participants were included. Two compared stretching with a control, one study compared stretching to an alternative intervention, one study compared stretching to both alternative and control interventions, and two compared different stretching techniques and durations. Quality rating on the modified Pedro scale varied from two to eight out of a maximum of ten points. The methodologies and interventions varied significantly between studies, making meta-analysis inappropriate. Most participants improved over the course of the studies, but when stretching was compared to alternative or control interventions, the changes only reached statistical significance in one study that used a combination of calf muscle stretches and plantar fascia stretches in their stretching programme. Another study comparing different stretching techniques, showed a statistically significant reduction in some aspects of pain in favour of plantar fascia stretching over calf stretches in the short term. Conclusions There were too few studies to assess whether stretching is effective compared to control or other interventions, for either pain or function. However, there is some evidence that plantar fascia stretching may be more effective than Achilles tendon stretching alone in the short-term.

Plantar heel pain can be managed with dry needling and/or injection of myofascial trigger points (MTrPs however the evidence for its effectiveness is uncertain. Therefore, we aimed to systematically review the current evidence for the effectiveness of dry needling and/or injections of MTrPs associated with plantar heel pain. Methods We searched specific electronic databases (MEDLINE, EMBASE, AMED, CINAHL, SPORTDiscus and AMI in April 2010 to identify randomised and non-randomised trials. We included trials where participants diagnosed with plantar heel pain were treated with dry needling and/or injections (local anaesthetics, steroids, Botulinum toxin A and saline alone or in combination with acupuncture. Outcome measures that focussed on pain and function were extracted from the data. Trials were assessed for quality using the Quality Index tool. Results Three quasi-experimental trials matched the inclusion criteria: two trials found a reduction in pain for the use of trigger point dry needling when combined with acupuncture and the third found a reduction in pain using 1% lidocaine injections when combined with physical therapy. However, the methodological quality of the three trials was poor, with Quality Index scores ranging form 7 to 12 out of a possible score of 27. A meta-analysis was not conducted because substantial heterogeneity was present between trials. Conclusions There is limited evidence for the effectiveness of dry needling and/or injections of MTrPs associated with plantar heel pain. However, the poor quality and heterogeneous nature of the included studies precludes definitive conclusions being made. Importantly, this review highlights the need for future trials to use rigorous randomised controlled methodology with measures such as blinding to reduce bias.

    Full Text Available Heel pain, mostly caused by plantar fasciitis (PF, is a common complaint of many patients who requiring professional orthopedic care and are mostly suffering from chronic pain beneath their heels. The present article reviews studies done by preeminent practitioners related to the anatomy of plantar fasciitis and their histo-pathological features, factors associated with PF, clinical features, imaging studies, differential diagnoses, and diverse treatment modalities for treatment of PF, with special emphasis on non-surgical treatment. Anti-inflammatory agents, plantar stretching, and orthosis proved to have highest priority; corticosteroid injection, night splints and extracorporeal shock wave therapy were of next priority, in patients with PF. In patients resistant to the mentioned treatments surgical intervention should be considered.

    Full Text Available Abstract Background There is considerable controversy regarding the effectiveness of extracorporeal shock wave therapy in the management of plantar heel pain. Our aim was to conduct a systematic review of randomised controlled trials to investigate the effectiveness of extracorporeal shock wave therapy and to produce a precise estimate of the likely benefits of this therapy. Methods We conducted a systematic review of all randomised controlled trials (RCTs identified from the Cochrane Controlled trials register, MEDLINE, EMBASE and CINAHL from 1966 until September 2004. We included randomised trials which evaluated extracorporeal shock wave therapy used to treat plantar heel pain. Trials comparing extra corporeal shock wave therapy with placebo or different doses of extra corporeal shock wave therapy were considered for inclusion in the review. We independently applied the inclusion and exclusion criteria to each identified randomised controlled trial, extracted data and assessed the methodological quality of each trial. Results Six RCTs (n = 897 permitted a pooled estimate of effectiveness based on pain scores collected using 10 cm visual analogue scales for morning pain. The estimated weighted mean difference was 0.42 (95% confidence interval 0.02 to 0.83 representing less than 0.5 cm on a visual analogue scale. There was no evidence of heterogeneity and a fixed effects model was used. Conclusion A meta-analysis of data from six randomised-controlled trials that included a total of 897 patients was statistically significant in favour of extracorporeal shock wave therapy for the treatment of plantar heel pain but the effect size was very small. A sensitivity analysis including only high quality trials did not detect a statistically significant effect.

    Plantar fasciitis is a common cause of heel pain. It is a disabling disease in its chronic form. It is a degenerative tissue condition of the plantar fascia rather than an inflammation. Various treatment options are available, including nonsteroidal anti-inflammatory drugs, corticosteroid injections, orthosis, and physiotherapy. This study compared the effects of local platelet-rich plasma, corticosteroid, and placebo injections in the treatment of chronic plantar fasciitis. In this double-blind study, patients were divided randomly into 3 groups. Local injections of platelet-rich plasma, corticosteroid, or normal saline were given. Patients were assessed with the visual analog scale for pain and with the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hindfoot score before injection, at 3 weeks, and at 3-month follow-up. Mean visual analog scale score in the platelet-rich plasma and corticosteroid groups decreased from 7.44 and 7.72 preinjection to 2.52 and 3.64 at final follow-up, respectively. Mean AOFAS score in the platelet-rich plasma and corticosteroid groups improved from 51.56 and 55.72 preinjection to 88.24 and 81.32 at final follow-up, respectively. There was a significant improvement in visual analog scale score and AOFAS score in the platelet-rich plasma and corticosteroid groups at 3 weeks and at 3-month follow-up. There was no significant improvement in visual analog scale score or AOFAS score in the placebo group at any stage of the study. The authors concluded that local injection of platelet-rich plasma or corticosteroid is an effective treatment option for chronic plantar fasciitis. Platelet-rich plasma injection is as effective as or more effective than corticosteroid injection in treating chronic plantar fasciitis. PMID:26913766

  5. Randomized multicenter follow-up trial on the effect of radiotherapy for plantar fasciitis (painful heels spur) depending on dose and fractionation – a study protocol

    International Nuclear Information System (INIS)

    An actual clinical trial showed the effect of low dose radiotherapy in painful heel spur (plantar fasciitis) with single doses of 1.0 Gy and total doses of 6.0 Gy applied twice weekly. Furthermore, a lot of animal experimental and in vitro data reveals the effect of lower single doses of 0.5 Gy which may be superior in order to ease pain and reduce inflammation in patients with painful heel spur. Our goal is therefore to transfer this experimentally found effect into a randomized multicenter trial. This was a controlled, prospective, two-arm phase III-multicenter trial. The standard arm consisted of single fractions of 1.0 Gy applied two times a week, for a total dose of 6.0 Gy (total therapy time: 3 weeks). The experimental arm consisted of single fractions of 0.5 Gy applied 3 times a week, for a total dose of 6.0 Gy (total therapy time: 4 weeks). Following a statistical power calculation, there were 120 patients for each investigation arm. The main inclusion criteria were: age > = 40 years, clinical and radiologically diagnosed painful heel spur (plantar fasciitis), and current symptoms for at least 6 months. The main exclusion criteria were: former local trauma, surgery or radiotherapy of the heel; pregnant or breastfeeding women; and a pre-existing severe psychiatric or psychosomatic disorder. After approving a written informed consent the patients are randomized by a statistician into one of the trial arms. After radiotherapy, the patients are seen after six weeks, after twelve weeks and then every twelve weeks up to 48 weeks. Additionally, they receive a questionnaire every six weeks after the follow-up examinations up to 48 weeks. The effect is measured using the visual analogue scale of pain (VAS), the calcaneodynia score according to Rowe and the SF-12 score. The primary endpoint is the pain relief three months after therapy. Patients of both therapy arms with an insufficient result are offered a second radiotherapy series applying the standard dose

    Chronic pressure ulcers (PrUs), ulcers that fail to progress through the expected phases of wound healing in a timely fashion, are not only a concern for the patients afflicted with them, but are also a significant burden for the long-term-care facilities in which patients reside. The heel is the second most common location for PrUs. Morbidity and mortality rates for heel PrUs, particularly in the diabetic population, are alarming. Therefore, a consistently effective, cost-conscious, and user-friendly topical treatment for heel ulcers would be welcomed by patients and clinicians. This article describes a marked and rapid improvement in wound granulation in 3 older adult patients following weekly treatment for 8 weeks of chronic (≥1-year duration) heel ulcers with an easy-to-use, cost-effective, topical, formulated collagen gel.

    Plantar fasciitis is a very common cause of inferior heel pain that can be triggered and aggravated by prolonged standing, walking, running and obesity, among other factors. Treatments are largely noninvasive and efficacious. Supportive treatments, including the plantar fascia-specific stretch, calf stretching, appropriate orthotics and night dorsiflexion splinting, can alleviate plantar fascia pain. While local injections of corticosteroids can help with pain relief, the effects are short-lived and must be weighed against the risk of fat pad atrophy and plantar fascia rupture. Ultrasonography-guided focal extracorporeal shock wave therapy is useful for patients with chronic plantar fasciitis and referrals for this treatment can be made in recalcitrant cases. Activity modification to decrease cyclical repetitive loading of the plantar fascia should be advised during the treatment phase regardless of the chosen treatment modality. PMID:27075037

    Plantar fasciitis (PF) is present in 10% of the population and is the most common cause of plantar heel pain. PF is painful, can alter daily activities and presents as a sharp pain localized to the plantar foot and medial heel. The underlying etiology involves microtrauma to the plantar fascia, specifically at its insertion point on the calcaneus. Successful management of plantar fasciitis is typically achieved with the conservative therapy approaches discussed. PMID:26665894

  10. Randomized multicenter trial on the effect of radiotherapy for plantar Fasciitis (painful heel spur) using very low doses – a study protocol

    International Nuclear Information System (INIS)

    A lot of retrospective data concerning the effect of radiotherapy on the painful heel spur (plantar fasciitis) is available in the literature. Nevertheless, a randomized proof of this effect is still missing. Thus, the GCGBD (German cooperative group on radiotherapy for benign diseases) of the DEGRO (German Society for Radiation Oncology) decided to start a randomized multicenter trial in order to find out if the effect of a conventional total dose is superior compared to that of a very low dose. In a prospective, controlled and randomized phase III trial two radiotherapy schedules are to be compared: standard arm: total dose 6.0 Gy in single fractions of 1.0 Gy applied twice a week experimental arm: total dose 0.6 Gy in single fractions of 0.1 Gy applied twice a week (acting as a placebo) Patients aged over 40 years who have been diagnosed clinically and radiologically to be suffering from a painful heel spur for at least six months can be included. Former trauma, surgery or radiotherapy to the heel are not allowed nor are patients with a severe psychiatric disease or women during pregnancy and breastfeeding. According to the statistical power calculation 100 patients have to be enrolled into each arm. After having obtaining a written informed consent a patient is randomized by the statistician to one of the arms mentioned above. After radiotherapy, the patients are seen first every six weeks, then regularly up to 48 months after therapy, they additionally receive a questionnaire every six weeks after the follow-up examinations. The effect is measured using several target variables (scores): Calcaneodynia-score according to Rowe et al., SF-12 score, and visual analogue scale of pain. The most important endpoint is the pain relief three months after therapy. Patients with an inadequate result are offered a second radiotherapy series applying the standard dose (equally in both arms). This trial protocol has been approved by the expert panel of the DEGRO as well as

    Plantar fasciitis is one the most common pathologies treated by foot and ankle surgeons. When nonoperative therapy fails, surgical intervention might be warranted. Various surgical procedures are available for the treatment of recalcitrant plantar fasciitis. The most common surgical management typically consists of open versus endoscopic plantar fascia release. Comorbidities associated with the release of the plantar fascia have been documented, including lateral column overload and metatarsalgia. We present an innovative technique for this painful condition that is minimally invasive, allows visualization of the plantar fascia, and maintains the integrity of the fascia. Our hypothesis was that the use of endoscopic debridement of the plantar fascia with or without heel spur resection would provide a minimally invasive technique with acceptable patient outcomes.

    Magnetic resonance (MR) imaging has emerged as an important noninvasive diagnostic imaging technique for assessment of foot pathology. This modality, owing to its multiplanar imaging capability and inherent superiority in contrast, has been shown to be more accurate and sensitive for detection of plantar fascia pathology than any other imaging method. One of the most important and recognizable causes of heel pain is plantar fasciitis. With the exception of plantar fasciitis, there has been little emphasis on imaging other conditions that affect this important structure. The objective of this review is to demonstrate, from a perspective of MR imaging, the many different pathologic conditions that affect the plantar fascia. Included in this review will be a discussion of normal anatomy as well as entities such as acute plantar fasciitis, chronic plantar fasciitis, traumatic rupture, normal post-surgical changes, pathologic post-fasciotomy conditions, infection, and fibromatosis.

    Full Text Available BACKGROUND: The risk factors for the development of plantar fasciitis (PF have been associated with the medial longitudinal arch (MLA, rearfoot alignment and calcaneal overload. However, the relationships between the biomechanical variables have yet to be determined. OBJECTIVE: The goal of this study was to investigate the relationships between the MLA, rearfoot alignment, and dynamic plantar loads in runners with unilateral PF in acute and chronic phases. METHOD: Cross-sectional study which thirty-five runners with unilateral PF were evaluated: 20 in the acute phase (with pain and 15 with previous chronic PF (without pain. The MLA index and rearfoot alignment were calculated using digital images. The contact area, maximum force, peak pressure, and force-time integral over three plantar areas were acquired with Pedar X insoles while running at 12 km/h, and the loading rates were calculated from the vertical forces. RESULTS: The multiple regression analyses indicated that both the force-time integral (R2=0.15 for acute phase PF; R2=0.17 for chronic PF and maximum force (R2=0.35 for chronic PF over the forefoot were predicted by an elevated MLA index. The rearfoot valgus alignment predicted the maximum force over the rearfoot in both PF groups: acute (R2=0.18 and chronic (R2=0.45. The rearfoot valgus alignment also predicted higher loading rates in the PF groups: acute (R2=0.19 and chronic (R2=0.40. CONCLUSION: The MLA index and the rearfoot alignment were good predictors of plantar loads over the forefoot and rearfoot areas in runners with PF. However, rearfoot valgus was demonstrated to be an important clinical measure, since it was able to predict the maximum force and both loading rates over the rearfoot.

    Chronic ankle instability (CAI) patients have been shown to have increased lateral column plantar pressure throughout the stance phase of gait. To date, traditional CAI rehabilitation programs have been unable to alter gait. We developed an auditory biofeedback device that can be worn in shoes that elicits an audible cue when an excessive amount of pressure is applied to a sensor. This study determined whether using this device can decrease lateral plantar pressure in participants with CAI and alter surface electromyography (sEMG) amplitudes (anterior tibialis, peroneus longus, medial gastrocnemius, and gluteus medius). Ten CAI patients completed baseline treadmill walking while in-shoe plantar pressures and sEMG were measured (baseline condition). Next, the device was placed into the shoe and set to a threshold that would elicit an audible cue during each step of the participant's normal gait. Then, participants were instructed to walk in a manner that would not trigger the audible cue, while plantar pressure and sEMG measures were recorded (auditory feedback (AUD FB) condition). Compared to baseline, there was a statistically significant reduction in peak pressure in the lateral midfoot-forefoot and central forefoot during the AUD FB condition. In addition, there were increases in peroneus longus and medial gastrocnemius sEMG amplitudes 200ms post-initial contact during the AUD FB condition. The use of this auditory biofeedback device resulted in decreased plantar pressure in the lateral column of the foot during treadmill walking in CAI patients and may have been caused by the increase in sEMG activation of the peroneus longus.

    To evaluate the sonographic findings of plantar fasciitis. Both feet of 30 patients(mean age, 44years) in whom plantar fasciitis had been clinically diagnosed, and those of healthy volunteers(mean age, 34years) were evaluated with ultrasound(US) using a 7.0MHz linear array transducer. Heel pain was unilateral in 26 patients and bilateral in four. Sagittal sonograms were obtained in the prone position, and the thickness of the plantar fascia was measured at its proximal end near its insertion into the calcaneus. We also evaluated hypoechoic fascia, perifascial fluid collection, fiber rupture, calcaneal spur and calcifications. Plantar fascia thickness was significantly greater in the heels of patients with plantar fasciitis(3.2-8mm; mean, 5.1{+-}1.12) than in their asymptomatic heels(1.3-5mm; mean, 3.5{+-}0.78)(p<0.0001), in which it was similar to that of heels of patients in the control group(1.8-5mm; mean, 3.0{+-}0.71)(p<0.0001). The proximal plantar fascia was hypoechoic in 31 symptomatic heels(91.2%), in four asymptomatic heels(15.4%), and in none of the patients in the control group. Calcaneal spurs were identified in sixteen symptomatic heels(47.1%), and in two which were asymptomatic(7.7%). Perifascial fluid collection was identified in only two symptomatic heels(5.9%). In plantar fasciitis, sonography demonstrates that the fascia is thicker as well as hypoechic. For the clinical diagnosis of planter fasciitis, US can therefore be used as an adjunct to clinical diagnosis.

    Full Text Available Heel pain is a common and frequently disabling clinical complaint that may be caused by a broad spectrum of osseous or soft-tissue disorders. "nThese disorders are classified on the basis of anatomic origin and predominant location of heel pain to foster a better understanding of this complaint. The disorders include plantar fascial lesions (fasciitis, rupture, fibromatosis, xanthoma, tendinous (tendonitis, tenosynovitis, osseous lesions (fractures, bone bruises, osteomyelitis, tumors, bursal lesions (retrocalcaneal bursitis, retroachilleal bursitis, tarsal tunnel syndrome, and heel plantar fat pad abnormalities. With its superior soft-tissue contrast resolution and multiplanar capability, magnetic resonance (MR imaging can help determine the cause of heel pain and help assess the extent and severity of the disease in ambiguous or clinically equivocal cases. Careful analysis of MR imaging findings and correlation of these findings with patient history and findings at physical examination can suggest a specific diagnosis in most cases. The majority of patients with heel pain can be successfully treated conservatively, but in cases requiring surgery (eg, plantar fascia rupture in competitive athletes, deeply infiltrating plantar fibromatosis, masses causing tarsal tunnel syndrome, MR imaging is especially useful in planning surgical treatment by showing the exact location and extent of the lesion

    The objective of this study was to evaluate the level of healing of chronic neuropathic plantar ulcers, using an irremovable windowed fibreglass cast boot, which is only opened after healing. A single-centre prospective study of a cohort of 177 diabetic patients with chronic neuropathic plantar ulcers was carried out. The duration of neuropathic plantar ulcers was 604 ± 808 days, with a mean surface area of 4.6 ± 6.5 cm(2) , a mean depth of 1.04 ± 1.08 cm and a mean volume of 5.9 ± 17.7 cm(3) . After a mean of 96 days of wearing a windowed fibreglass cast boot (min 9 days, max 664 days and median 68 days), the level of healing reached 83.6%, although 29 patients did not heal (16.4%). The compliance was at 95%. NPUs with bigger volumes (p = 0.037) and those located at the heels ( p = 0.004) had significantly lower healing levels. Twenty-one patients had moderate peripheral arterial disease (12%), and 24 patients were ostectomized for underlying osteomyelitis (14%), before inclusion. Moderate peripheral arterial disease (p = 0.970) or operated osteomyelitis (p = 0.128) did not modify the level of healing significantly, which were of 81% and 70.8%, respectively. Complications include 12 ulcers due to the windowed fibreglass cast boot (i.e. 7%) and two other ulcers being moderately infected, resulting in 2% of toe amputation, but there was no major amputation or phlebitis. The treatment of old and deep NPUs of the diabetic foot by wearing a windowed fibreglass cast boot without opening the boot prior to healing offers very high ulcer recovery levels. Windowed fibreglass cast boots were changed in only 26 cases (14.6%). In addition, compliance was excellent and of the order of 95%. Furthermore, moderate peripheral arterial disease or a recent ostectomy did not affect the efficacy of windowed fibreglass cast boot. PMID:25941091

    Full Text Available Objective: This paper has the purpose to analyze prospectively the treatment results in patients with chronic plantar fasciitis resistant to conservative treatment who underwent extracorporeal shock wave therapy (ESWT. Methods: We evaluated 30 patients (36 feet; 16 (53.3% patients were male and 14 (47.7% female with mean age of 48.7 y.o., varying from 33 to 78 y.o.; 16 (53.3% present the problem on the left side, 14 (46.7% on the right ones and 6 (20% bilateral; the symptomatology varied from 6 to 60 months, with the average of 13.58 months. These patients were submitted to a weekly ESWT session for 4 consecutive weeks. We measured the plantar fascia thickness millimeters with ultrasound and we applied American Orthopaedic Foot and Ankle Society (AOFAS scale for ankle and hindfoot, and Roles & Maudsley scales in pre ESWT, after one, three and six months after and decrease in the plantar fascia thickness by the ultrasound (p = 0.011 along the different moments studied. Results: We observed improvement of the evaluated criteria (p < 0.001 and plantar fascia thickness by ultrasound (p = 0.011 at different time points studied. Conclusion: The ESWT can be considered an important tool in the primary or adjuvant treatment of the chronic plantar fasciitis when associated with conventional therapies. This methodology is safe, non-invasive and provides precocious rehabilitation and return to regular activities considering the results of the statistical analysis. This resource provides decrease in the thickness of the plantar fascia.

    Full Text Available Nicolò Martinelli, Carlo Bonifacini, Giovanni RomeoDepartment of Ankle and Foot Surgery, IRCCS Galeazzi Orthopaedic Institute, Milan, ItalyAbstract: Almost 1 million Americans are affected by plantar fasciitis (PF, which is the commonest cause of chronic heel pain. This condition is often managed conservatively, and many rehabilitation protocols, some with the aid of orthoses, have been adopted, with good-to-excellent clinical results. Although most cases of chronic PF can be successfully managed with a conservative approach, alternative treatments, including high-energy shock wave therapy and corticosteroid injections, are commonly accepted as second-line treatment when traditional conservative therapy fails. However, surgery is still an important mode of treatment. Recently, new minimally invasive surgical techniques that offer numerous advantages (faster recovery time, early weight-bearing, lower postoperative pain over standard surgical approaches have been proposed, with good results and low complication rates. The purpose of this review is to report new conservative and surgical techniques for the treatment of PF. A literature search for articles about plantar fasciitis was conducted on the PubMed database in order to identify publications addressing the treatments of PF. The literature suggests that, initially, traditional conservative treatments consisting of rest, oral nonsteroidal anti-inflammatory drugs, foot orthotics, and stretching exercises can be tried for several weeks. In patients with chronic recalcitrant PF, extracorporeal shock wave therapy or corticosteroid injection can be considered. Surgery (minimally invasive techniques should be considered only after failure of the conservative treatments.Keywords: heel pain, surgery, plantar fasciosis

  12. Spectrum of Ultrasound Pathologies of Achilles Tendon, Plantar Aponeurosis and Flexor Digiti Brevis Tendon Heel Entheses in Patients with Clinically Suspected Enthesitis

    International Nuclear Information System (INIS)

    Enthesitis is considered a characteristic presentation of the second most common group of rheumatoid disorders, i.e. spondyloarthropathies (SpAs), particularly peripheral spondyloarthropathies. At the initial stages, enthesitis may be the only symptom of SpA, particularly in patients lacking the HLA-B27 receptor. In light of diagnostic difficulties with detecting enthesitis in clinical examinations and laboratory investigations, many studies point out the high specificity of imaging studies, and particularly ultrasonography. A total of 20% Achilles tendon entheses, 45% plantar aponeurosis entheses and 89.5% of flexor digiti brevis tendon entheses were unremarkable. In the remaining cases, the presentation of pathological lesions was not specific to enthesitis and might more likely correspond to degeneration or microinjuries of the entheses, beside the most obvious cases of achillobursitis or Kager’s fat pad inflammation. The studies demonstrated that ultrasound scans rarely confirm the clinical diagnosis of enthesitis

    Clinical Question In adults with acute plantar fasciitis whose symptoms have not been relieved with the conventional regimen of NSAIDS, stretching and lifestyle modification, do the addition of orthotics (prefabricated or custom fitted) reduce pain and improve function compared with other non-surgical treatments (manipulative chiropractic, physical therapy and/or heel steroid injections)? Answer Yes. Studies have shown that orthotics, both prefabricated and custom fitted, reduce pain and improve function in adults with acute plantar fasciitis with few risks or side effects. Used alone or in addition to conventional therapy (NSAIDs, stretching, lifestyle modification), orthotics are effective and well tolerated by patients for short-term pain relief and improved function. Prefabricated orthotics are less costly and provide similar relief to more expensive custom orthotics. Level of Evidence of the Answer A Search Terms Plantar fasciitis, heel pain, treatment, orthotics, Limits Adult, human, English, Review, Randomized-Control Trials, Systematic Reviews, adults age 18 or more, publication dates 2004 to present. Date Search was Conducted January 16, 2014; updated January 20, 2015 Inclusion Criteria Recent published systematic reviews, randomized controlled, meta-analyses; adults with confirmed acute or recent diagnosis of plantar fasciitis. Exclusion Criteria Studies older than 10 years, children, adolescents less than 18 years of age, chronic or recalcitrant plantar fasciitis. PMID:26855444

    absolute values for pain intensity (at first, eighth, and last session showed similarity between groups. The improvement percentage for 15 sessions did not present differences between both groups. That percentage was also calculated for two periods (before and after the eighth session. It was noted that the improvement percentage on all 15 sessions for group 2 (46.5% was inferior to the percentage of the first eighth sessions for group 1 (54.6%. Thus, the high-power continuous ultrasound did not add value for function and pain; additionally, only specific stretching exercises were efficient in reducing more than 50% of the pain in chronic plantar fasciitis.

    Purpose: We have investigated the role of sonography in the diagnosis of plantar fasciitis. Materials and methods: This study evaluates 39 patients with plantar fasciitis and control group of 22 healthy volunteers. The plantar fascia thickness was measured 5 mm distal to the insertion of the calcaneus of plantar aponeurosis. Qualitative parameters such as decreased echogenity, biconvexity, perifascial fluid and calcification of plantar fascia were also noted. Results: Mean plantar fascia thickness was measured 2.9 mm in patients with unilateral heel pain, 2.2 mm for contralateral normal heel and 2.5 mm for control group. There was a statistically significant difference between heel with plantar fasciitis, contralateral normal heel and control groups (p = 0.009 and 0.0001, respectively). Mean body mass index was 28 kg/m{sup 2} in patients with heel pain and 25 kg/m{sup 2} in control group. Body mass index measurements were significantly different between plantar fasciitis and control groups. We found reduced plantar fascia echogenity in 16 cases (41%), calcaneal spur in 20 cases (51%), biconvex appearance in two cases (5.1%) and perifascial fluid in one case (2.5%). Conclusion: We conclude that in patients with plantar fasciitis, ultrasound may detect relatively small differences in plantar fascia thickness even in clinically unequivocal plantar fasciitis.

    Therapeutic use of high-amplitude pressure waves, or shock wave therapy (SWT), is emerging as a popular method for treating musculoskeletal disorders. However, the mechanism(s) through which this technique promotes healing are unclear. Finite element models of a shock wave source and the foot were constructed to gain a better understanding of the mechanical stimuli that SWT produces in the context of plantar fasciitis treatment. The model of the shock wave source was based on the geometry of an actual radial shock wave device, in which pressure waves are generated through the collision of two metallic objects: a projectile and an applicator. The foot model was based on the geometry reconstructed from magnetic resonance images of a volunteer and it comprised bones, cartilage, soft tissue, plantar fascia, and Achilles tendon. Dynamic simulations were conducted of a single and of two successive shock wave pulses administered to the foot. The collision between the projectile and the applicator resulted in a stress wave in the applicator. This wave was transmitted into the soft tissue in the form of compression-rarefaction pressure waves with an amplitude of the order of several MPa. The negative pressure at the plantar fascia reached values of over 1.5 MPa, which could be sufficient to generate cavitation in the tissue. The results also show that multiple shock wave pulses may have a cumulative effect in terms of strain energy accumulation in the foot. PMID:26465270

    Relevance: Plantar fasciitis, the most common cause of heel pain, is due to repetitive strain injury to the medial arch and the heel, causing functional disabilities. Any biomechanical alteration in the lower extremity has its effect on plantar fascia. Kaltenborn mobilization techniques have been proved effective in improving the range of motion of the affected joints. There is a need to evaluate these techniques in plantar fasciitis by treating whole lower extremity. Participants: 20 subj...

  2. Mechanical Information of Plantar Fascia during Normal Gait

    Gu, Yaodong; Li, Zhiyong

    The plantar fascia is an important foot tissue in stabilizing the longitudinal arch of human foot. Direct measurement to monitor the mechanical situation of plantar fascia at human locomotion is difficult. The purpose of this study was to construct a three-dimensional finite element model of the foot to calculate the internal stress/strain value of plantar fascia during different stage of gait. The simulated stress distribution of plantar fascia was the lowest at heel-strike, which concentrated on the medial side of calcaneal tubercle. The peak stress of plantar fascia was appeared at push-off, and the value is more than 5 times of the heel-strike position. Current FE model was able to explore the plantar fascia tension trend at the main sub-phases of foot. More detailed fascia model and intrinsic muscle forces could be developed in the further study.

    Full Text Available Background and Objectives: Plantar fasciitis is a common foot disorder in which patients have pain and tenderness at the sole of the foot. Rest, exercises, orthotics, taping, cryotherapy, therapeutic ultrasound, electrical stimulation, whirlpool bath, and iontophoresis have been widely used to relieve plantar pain. Long term use of manual therapy techniques like myofascial release technique, positional release therapy and passive stretching have been used in the past to reduce pain and improve ankle range of motion. The present study aimed to evaluate and compare the immediate effectiveness of myofascial release technique, positional release therapy and passive stretching on pain response and ankle flexibility in chronic plantar fasciitis. Material and methodology: A total of 60 participants with chronic plantar fasciitis were randomly allocated to Group A (myofascial release group and Group B (positional release group and Group C (passive stretching. Therapeutic ultrasound with intensity of 1W/cm2 and frequency of 1MHz for 5 min was given for a single session to all the patients and then given the manual techniques. Visual analogue scale, range of motion of the ankle were outcome measures that were assessed pre- and immediately post-interventional. Results: The study demonstrated statistical significant reduction in pain, in all three groups (p<0.0001. Ankle range of motion showed significant improvement in Group A (MFR. Group C (passive stretching demonstrated significant improvement (p=0.001 as compared to Group B (PRT. Conclusion: All three manual techniques with therapeutic ultrasound were effective in immediate relief of pain and improving ankle range of motion in subjects with chronic plantar fasciitis.

This evaluation also highlights emerging minimally invasive therapies that exploit these mechanisms in recalcitrant PF.

  5. Long-term results of radiotherapy in patients with chronic palmo-plantar eczema or psoriasis

    International Nuclear Information System (INIS)

    Background and Purpose: Radiotherapy (RT) is well accepted for therapy-refractory palmo-plantar eczema or psoriasis, despite of lacking evidence regarding beneficial long term effects. Furthermore, the optimal irradiation dose is unknown. We evaluated the outcome of RT with two different RT single/total dose (SD/TD) treatment policies. Patients and Methods: 28 consecutive patients with therapy-refractory eczema (n = 22) or psoriasis (n 6) of palms and/or soles were irradiated twice a week either with a Dmax SD of 1 Gy (6/98-5/03; median TD: 12 Gy) or 0.5 Gy (6/03-7/04; median TD: 5 Gy). Median age was 52 years (27-71), median follow-up 20 months (4-76). Totally 88 regions were treated, 49 with 1 Gy, 39 with 0.5 Gy SD. Eight different symptoms were scored from 0 (absent) -3 (severe), giving a possible sum score of 0-24. Patients' rating of RT result was also documented (worse/stable/better/complete remission). Results: The sum score was 15 (6-23) before RT, 2 (0-16) at the end of RT, and 1 (0-21) at last follow-up, respectively. The improvement was highly significant in both treatment regimens. Better or complete remission by the patients were reported in 44 and 39 (= 83 out of 88) localisations, that was often stable during the follow-up. 5 (6%) regions in 3 (11%) patients didn't benefit from RT. Conclusion: RT reveals excellent results in palmo-plantar eczema or psoriasis. We recommend a SD of 0.5 Gy twice a week up to a TD of 4-5 Gy. (orig.)

  7. MRI of the plantar structures of the foot after falanga torture

    International Nuclear Information System (INIS)

    Falanga is an ancient form of punishment or torture but is still commonly reported by our refugees. The late result of caning the heel and ball of the foot is a chronic painful condition with few clinical signs. The aim of the present study was to assess, by MRI, possible morphologic characteristics of the heel and ball of the foot, related to falanga and pain in correlation to clinical findings. Magnetic resonance imaging of the foot was obtained in 12 victims exposed to falanga torture and 9 healthy volunteers. Sagittal T1-weighted spin-echo images (TR 616-840 ms, TE 20 ms), T2-weighted spin-echo images (TR 1900 ms, TE 90 ms), and short tau inversion recovery (STIR) images (TR 1200 ms, TE 15 ms, TI 100 ms) were performed. The central portion of the plantar aponeurosis was generally significantly thicker in victims exposed to falanga torture as compared with that of controls (P < 0.05). In all except one of the victims, MRI demonstrated two layers of the thickened plantar aponeurosis: a deeper portion with normal homogeneous low signal intensity (SI) appearance, and a superficial layer with characteristic areas of mixed SI on both T1- and T2-weighted images. There were no signs of chronic muscular compartment syndromes, and the thickness of the plantar pad did not differ between the two groups. Magnetic resonance imaging may demonstrate morphologic characteristics of the plantar aponeurosis which may confirm falanga torture. Further imaging with more specific sequences is warranted to demonstrate the supposed injuries in the compartmental fat tissue chambers and the vascularity of the ball pad of the foot. (orig.)

    At present, MRI is the only imaging method that can precisely visualize lesions of the superficial plantar aponeurosis, whether they be musculoaponeurositides, enthesopathies or tears, and whether they be acute or chronic, with or without complications. By its direct visualization of the lesion, MRI enables an accurate assessment of the injury to be made and thereby better orients the therapeutic strategy. (orig.) With 11 figs., 15 refs.

    2011-09-26

    The plantar surface of the foot senses local pressures during stance and locomotion. These foot loading characteristics may be affected by long distance running. Little is known about the physiological effects of sports-related loading on plantar sensitivity and their relationship with plantar foot loading. The purpose of this study was to investigate the acute effects of long distance running on plantar sensitivity to touch and their relationship with foot loading characteristics. It was hypothesized that plantar sensation would decrease after long distance running and may be related to foot loading characteristics. In 15 middle-aged runners, sensory detection thresholds to light touch and plantar pressures were measured before and after a 10 km run. After the run, no significant changes in sensory perception thresholds were observed so that correlations between foot sensitivity and foot loading could not be calculated. A significant decrease of force-time integrals and maximum forces was demonstrated in the whole foot (-6.2%, p=0.003; -3.9%, p=0.001) and the heel (-10.5%, p=0.003; -8.5%, p=0.002). Furthermore, maximum force was significantly reduced in the lateral midfoot (-6.4%, p=0.002). In conclusion, a sub-maximal 10 km running exercise appears to have no significant acute effects on plantar sensitivity, plantar pressure distribution and peak forces. PMID:21871535

  11. Ultrasound guided injection of dexamethasone versus placebo for treatment of plantar fasciitis: protocol for a randomised controlled trial

    2010-07-01

    Full Text Available Abstract Background Plantar fasciitis is the most commonly reported cause of chronic pain beneath the heel. Management of this condition commonly involves the use of corticosteroid injection in cases where less invasive treatments have failed. However, despite widespread use, only two randomised trials have tested the effect of this treatment in comparison to placebo. These trials currently offer the best available evidence by which to guide clinical practice, though both were limited by methodological issues such as insufficient statistical power. Therefore, the aim of this randomised trial is to compare the effect of ultrasound-guided corticosteroid injection versus placebo for treatment of plantar fasciitis. Methods The trial will be conducted at the La Trobe University Podiatry Clinic and will recruit 80 community-dwelling participants. Diagnostic ultrasound will be used to diagnose plantar fasciitis and participants will be required to meet a range of selection criteria. Participants will be randomly allocated to one of two treatment arms: (i ultrasound-guided injection of the plantar fascia with 1 mL of 4 mg/mL dexamethasone sodium phosphate (experimental group, or (ii ultrasound-guided injection of the plantar fascia with 1 mL normal saline (control group. Blinding will be applied to participants and the investigator performing procedures, measuring outcomes and analysing data. Primary outcomes will be pain measured by the Foot Health Status Questionnaire and plantar fascia thickness measured by ultrasound at 4, 8 and 12 weeks. All data analyses will be conducted on an intention-to-treat basis. Conclusion This will be a randomised trial investigating the effect of dexamethasone injection on pre-specified treatment outcomes in people with plantar fasciitis. Within the parameters of this protocol, the trial findings will be used to make evidence-based recommendations regarding the use of corticosteroid injection for treatment of this

  14. Randomized, Multicenter Trial on the Effect of Radiation Therapy on Plantar Fasciitis (Painful Heel Spur) Comparing a Standard Dose With a Very Low Dose: Mature Results After 12 Months' Follow-Up

    International Nuclear Information System (INIS)

    Purpose: To conduct a randomized trial of radiation therapy for painful heel spur, comparing a standard dose with a very low dose. Methods and Materials: Sixty-six patients were randomized to receive radiation therapy either with a total dose of 6.0 Gy applied in 6 fractions of 1.0 Gy twice weekly (standard dose) or with a total dose of 0.6 Gy applied in 6 fractions of 0.1 Gy twice weekly (low dose). In all patients lateral opposing 4- to 6-MV photon beams were used. The results were measured using a visual analogue scale, the Calcaneodynia score, and the SF12 health survey. The fundamental phase of the study ended after 3 months, and the follow-up was continued up to 1 year. Patients with insufficient pain relief after 3 months were offered reirradiation with the standard dosage at any time afterward. Results: Of 66 patients, 4 were excluded because of withdrawal of consent or screening failures. After 3 months the results in the standard arm were highly significantly superior compared with those in the low-dose arm (visual analogue scale, P=.001; Calcaneodynia score, P=.027; SF12, P=.045). The accrual of patients was stopped at this point. Further evaluation after 12 months' follow-up showed the following results: (1) highly significant fewer patients were reirradiated in the standard arm compared with the low-dose arm (P<.001); (2) the results of patients in the low-dose arm who were reirradiated were identical to those in the standard arm not reirradiated (reirradiation as a salvage therapy if the lower dose was ineffective); (3) patients experiencing a favorable result after 3 months showed this even after 12 months, and some results even improved further between 3 and 12 months. Conclusions: This study confirms the superior analgesic effect of radiation therapy with 6-Gy doses on painful heel spur even for a longer time period of at least 1 year.

    Many heel pathologies including plantar heel pain may result from micro tears/trauma in the subcutaneous tissues, in which internal tissue deformation/stresses within the heel pad play an important role. Previously, many finite element models have been proposed to evaluate stresses inside the heel pad, but the majority of these models only focus on static loading boundary conditions. This study explored a dynamics modelling approach to the heel pad subjected to realistic impact loads during running. In this model, the inertial property and action of the body are described by a lumped parameter model, while the heel/shoe interactions are modelled using a viscoelastic heel pad model with contact properties. The impact force pattern, dynamic heel pad deformation and stress states predicted by the model were compared with published experimental data. Further parametrical studies revealed the model responses, in terms of internal stresses in the skin and fatty tissue, change nonlinearly when body dynamics changes. A reduction in foot's touchdown velocity resulted in a less severe impact landing and stress relief inside the heel pad, for example peak von-Mises stress in fatty tissue, was reduced by 11.3%. Applications of the model may be extendable to perform iterative analyses to further understand the complex relationships between body dynamics and stress distributions in the soft tissue of heel pad during running. This may open new opportunities to study the mechanical aetiology of plantar heel pain in runners. PMID:24980181

  20. Randomized multicenter follow-up trial on the effect of radiotherapy on painful heel spur (plantar fasciitis) comparing two fractionation schedules with uniform total dose: first results after three months’ follow-up

    International Nuclear Information System (INIS)

    Our first trial on radiotherapy for painful heel spur published in 2012 comparing the analgesic effect of a standard dose (6 × 1.0Gy within three weeks) to that of a very low one (6 × 0.1Gy within three weeks) resulted in a highly significant superiority of the standard dose arm. In the meantime, experimental data have shown that lower single doses in the range of 0.5 – 0.7Gy might be even more effective than the current standard dose of 1.0 Gy. Therefore, we conducted a second trial comparing the analgesic effect of standard single doses of 1.0Gy to that of low single doses of 0.5Gy using uniform total doses of 6Gy. One hundred twenty-seven patients were randomized to receive radiation therapy either with a total dose of 6.0Gy applied in 6 fractions of 1.0Gy twice weekly (standard dose) or with the same total dose applied in 12 fractions of 0.5Gy three times weekly (experimental dose). In all patients lateral opposing 6MV photon beams were used. The results were measured using Visual analogue scale (VAS), Calcaneodynia score (CS) and SF-12 health survey. The first phase of this trial ended after a three months’ follow-up; it will be continued up to 48 weeks. Nine patients had to be excluded after randomization either due to the withdrawal of informed consent to radiotherapy by the patients or radiotherapy with an incorrect dosage. The groups were comparable concerning biographical and disease data. The mean calcaneodynia score (CS) was higher in the experimental group (p = 0.002). After three months’ follow-up, we saw a very favorable pain relief in both arms (decline of VAS score: standard arm 42 points, experimental arm 44 points (n.s.), but we did not notice any statistically significant difference between the arms neither concerning the pain parameters nor the quality of life parameters. No relevant acute side effects were recorded. Favorable laboratory results could not be translated into an enhanced pain relief in our patients. This trial was

    Full Text Available Aim: Plantar fasciitis (PF is a painful and disabling disease that affects the quality of life and daily activities of patients and it is the most common cause of heel pain in adults. In primary treatment, conservative treatment is suggested and different conservative options are described in the literature. In our study, we evaluated the efficacy of plantar fascia-specific stretching exercises in the treatment of PF. Methods: Twenty-nine feet - 21 patients with the mean age of 49.3 years were included in the study. The mean length of follow-up was 19.8 months and the mean length of exercise period was 4.94 months. Non-weight bearing plantar fascia-specific stretching exercise was done twice daily, for 10 times at each session. In addition to exercises, silicone heel pad and nonsteroidal anti-inflammatory drugs (NSAID were added. Visual analog scale (VAS was used for pain evaluation. Results: Full recovery detected in 15 feet in 10 patients (52% and a decrease in pain was seen in 10 feet in 8 patients (34%. There was no response in 4 feet in 3 patients (14%. There was statistically significant difference between pre-treatment and post-treatment visual analog scale scores (p=0.0001. Conclusion: Plantar fascia-specific stretching exercise is an effective treatment option in PF.

    Various therapeutic options are available for treatment of recalcitrant plantar fasciitis. Studies using TOPAZ coblation (ArthroCare, Sunnyvale, CA) have had good early results. The current coblation technique involves a surgical incision or breach of the highly specialized plantar fat pad, which can be associated with risks. We describe a novel technique of ultrasound-guided percutaneous coblation with a lateral heel approach. Advantages include precise targeting of the plantar fascia by direct dynamic visualization of the coblation tip, a true percutaneous approach with a needle skin puncture (plantar fat pad by using a lateral heel approach.

    Full Text Available The diagnosis of plantar fasciitis is usually clinical and rarely needs to be investigated further. The patient complains of pain in the medial side of the heel, most noticeable with initial steps after a period of inactivity and usually lessens with increasing level of activity during the day, but will tend to worsen toward the end of the day. Symptoms may become worse following prolonged weight bearing, and often precipitated by increase in weight bearing activities. Paresthesia is uncommon. It is usually unilateral, but up to 30% of cases have a bilateral presentation. In our study patients who received chiropractic therapy were treated by rest, heat, ice pack, non-steroidal anti-inflammatory drugs (NSAIDS, heel pads, magnetic insole, night splints, walking cast, taping, ultrasound, plantar and Achilles stretching for a period of 6 weeks scheduled accordingly. Patients receiving corticosteroid injection were administered 80mg methyl prednisolone locally at the heel. Each patient received 3 doses of methyl prednisolone injections on 1st day, 2nd week, and 4th week. The results with corticosteroid injection were better when analyzed with numeric rating scale over a period of 6 weeks. [Int J Res Med Sci 2014; 2(2.000: 639-642

  6. Effect of Field Size and Length of Plantar Spur on Treatment Outcome in Radiation Therapy of Plantar Fasciitis: The Bigger the Better?

    International Nuclear Information System (INIS)

    Purpose: Radiation therapy is well established in the treatment of painful plantar fasciitis or heel spur. A retrospective analysis was conducted to investigate the effect of field definition on treatment outcome and to determine the impact of factors potentially involved. Methods and Materials: A review of treatment data of 250 patients (285 heels) with a mean follow-up time of 11 months showed that complete symptom remission occurred in 38%, partial remission in 32%, and no change in 19% (11% were lost to follow-up). Variables such as radiologic evidence of plantar spurs, their length, radiation dose, field size, age, sex, and onset of pain before administration of radiation therapy were investigated in univariate and multivariate regression analyses. Results: Treatment response depended upon age >53 years, length of heel spur ≤6.5 mm (or no radiologic evidence of a heel spur), and onset of pain <12 months before radiation therapy. Patients with these clinical prerequisites stood a 93% chance of clinical response. Without these prerequisites, only 49% showed any impact. No influence of field size on treatment outcome became evident. Conclusion: Patients with short plantar heel spurs benefit from radiation therapy equally well as patients without any radiologic evidence. Moreover, smaller field sizes have the same positive effect as commonly used large field definitions covering the entire calcaneal bone. This leads to a recommendation of a considerable reduction of field size in future clinical practice

    Objective To investigate differences in plantar pressure distribution between a normal gait and unpredictable slip events to predict the initiation of the slipping process. Methods Eleven male participants were enrolled. Subjects walked onto a wooden tile, and two layers of oily vinyl sheet were placed on the expected spot of the 4th step to induce a slip. An insole pressure-measuring system was used to monitor plantar pressure distribution. This system measured plantar pressure in four regions (the toes, metatarsal head, arch, and heel) for three events: the step during normal gait; the recovered step, when the subject recovered from a slip; and the uncorrected, harmful slipped step. Four variables were analyzed: peak pressure (PP), contact time (CT), the pressure-time integral (PTI), and the instant of peak pressure (IPP). Results The plantar pressure pattern in the heel was unique, as compared with other parts of the sole. In the heel, PP, CT, and PTI values were high in slipped and recovered steps compared with normal steps. The IPP differed markedly among the three steps. The IPPs in the heel for the three events were, in descending order (from latest to earliest), slipped, recovered, and normal steps, whereas in the other regions the order was normal, recovered, and slipped steps. Finally, the metatarsal head-to-heel IPP ratios for the normal, recovered, and slipped steps were 6.1±2.9, 3.1±3.0, and 2.2±2.5, respectively. Conclusion A distinctive plantar pressure pattern in the heel might be useful for early detection of a slip event to prevent slip-related injuries. PMID:26798603

    Falanga is an ancient form of punishment or torture but is still commonly reported by our refugees. The late result of caning the heel and ball of the foot is a chronic painful condition with few clinical signs. The aim of the present study was to assess, by MRI, possible morphologic characteristics of the heel and ball of the foot, related to falanga and pain in correlation to clinical findings. Magnetic resonance imaging of the foot was obtained in 12 victims exposed to falanga torture and 9 healthy volunteers. Sagittal T1-weighted spin-echo images (TR 616-840 ms, TE 20 ms), T2-weighted spin-echo images (TR 1900 ms, TE 90 ms), and short tau inversion recovery (STIR) images (TR 1200 ms, TE 15 ms, TI 100 ms) were performed. The central portion of the plantar aponeurosis was generally significantly thicker in victims exposed to falanga torture as compared with that of controls (P ball pad of the foot. PMID:11044943

    2008-08-01

    Full Text Available Abstract Background Plantar calcaneal spurs are common, however their pathophysiology is poorly understood. This study aimed to evaluate the prevalence and correlates of plantar calcaneal spurs in a large sample of older people. Methods Weightbearing lateral foot radiographs of 216 people (140 women and 76 men aged 62 to 94 years (mean age 75.9, SD 6.6 were examined for plantar calcaneal and Achilles tendon spurs. Associations between the presence of spurs and sex, body mass index, radiographic measures of foot posture, self-reported co-morbidities and current or previous heel pain were then explored. Results Of the 216 participants, 119 (55% had at least one plantar calcaneal spur and 103 (48% had at least one Achilles tendon spur. Those with plantar calcaneal spurs were more likely to have Achilles tendon spurs (odds ratio [OR] = 2.0, 95% confidence interval [CI] 1.2 to 3.5. Prevalence of spurs did not differ according to sex. Participants with plantar calcaneal spurs were more likely to be obese (OR = 7.9, 95% CI 3.6 to 17.0, report osteoarthritis (OR = 2.6, 95% CI 1.6 to 4.8 and have current or previous heel pain (OR = 4.6, 95% CI 2.3 to 9.4. No relationship was found between the presence of calcaneal spurs and radiographic measures of foot posture. Conclusion Calcaneal spurs are common in older men and women and are related to obesity, osteoarthritis and current or previous heel pain, but are unrelated to radiographic measurements of foot posture. These findings support the theory that plantar calcaneal spurs may be an adaptive response to vertical compression of the heel rather than longitudinal traction at the calcaneal enthesis.

    Full Text Available Plantar heel pain is a commonly encountered Orthopaedic problem in women that can cause significant discomfort and difficulty in bearing weight. Proximal plantar fasciitis is twice as common in women as in men (2. An infracalcaneal spur frequently is associated with the symptomatology of plantar fasciitiss. METHODS AND MATERIAL: It’s a retrograded study of 72 female patients came in orthopaedics OPD with complain of planter heel pain. Age more than 30 years. Out of 72 patients, 59 were peri menopausal age group (> 40 years and 13 were younger age group (30-40 years. 43 patients had radiological evidence of calcaneal spur. 29 patients have bilateral heel pain. We treated all these patients by life style modification, use of heel pads, stretching exercise of foot and ankle, analgesics (as and when required calcium and calcitriol supplementation for 3 months. In 25 cases the diagnosis were made planter fasciitis and one foot is involved more with point tenderness persisted after 2 weeks of above mention treatment, we gave intra- lesion methyl prednisolone injection along with above mention treatment. DISCUSSION: We found 45.83% of patient s responded to this treatment within one month, 70.83% responded within 3 months and 65.27% showed improvement even after 6 months. CONCLUSION: Treatment of plantar heel pain should proceed in a stepwise fashion and, according to the patient’s response, as follows. First, modify or suppress the alleged risk factors, give an NSAID, prescribe a stretching program for the Achilles tendon, and recommend orthotics such as heel pads .Calcium and calcitriol supplementation specially in peri menopausal women with bilateral heal pain. If these fail, give one or two local injections of a methylprednisolone.

    Full Text Available Plantar fasciitis (PF is the most common cause of chronic heel pain which may be bilateral in 20 to 30% of patients. It is a very painful and disabling condition which can affect the quality of life. The management includes both pharmacological and operative procedures with no single proven effective treatment modality. In the present case series, we managed three patients with PF (one with bilateral PF. Following a diagnostic medial calcaneal nerve (MCN block at its origin, we observed reduction in verbal numerical rating scale (VNRS in all the three patients. Two patients has relapse of PF pain which was managed with MCN block followed with pulsed radio frequency (PRF. All the patients were pain-free at the time of reporting. This case series highlights the possible role of combination of diagnostic MCN block near its origin followed with PRF as a new modality in management of patients with PF.

    2015-03-01

    Chronic plantar fasciitis is a major health care problem worldwide and affects nearly 10% of the US population. Although most cases resolve with conservative care, the numerous treatments for refractory plantar fasciitis attest to the lack of consensus regarding these cases. The emerging goals for this condition are a minimally invasive percutaneous intervention that is safe, effective, and well-tolerated and has minimal morbidity and a low complication rate. We conducted a prospective study in which patients were allowed either to continue with noninvasive treatment or to undergo focal aspiration and partial fasciotomy with an ultrasonic probe. This is the first report of a plantar fascia partial release guided by ultrasonic energy delivered by a percutaneously inserted probe under local anesthesia. The procedure appears to be a safe, effective, well-tolerated treatment for a condition that is refractory to other options. PMID:25750942

    Conservative treatments such as in-shoe orthotic heel wedges to treat musculoskeletal injuries are not new. However, weak evidence supporting their use in the management of Achilles tendonitis suggests the mechanism by which these heel wedges works remains poorly understood. It was the aim of this study to test the underlying hypothesis that heel wedges can reduce Achilles tendon load. A musculoskeletal modeling approach was used to quantify changes in lower limb mechanics when walking due to the introduction of 12-mm orthotic heel wedges. Nineteen healthy volunteers walked on an inclinable walkway while optical motion, force plate, and plantar pressure data were recorded. Walking with heel wedges increased ankle dorsiflexion moments and reduced plantar flexion moments; this resulted in increased peak ankle dorsiflexor muscle forces during early stance and reduced tibialis posterior and toe flexor muscle forces during late stance. Heel wedges did not reduce overall Achilles tendon force during any walking condition, but did redistribute load from the medial to lateral triceps surae during inclined walking. These results add to the body of clinical evidence confirming that heel wedges do not reduce Achilles tendon load and our findings provide an explanation as to why this may be the case.

    Chronic Achilles tendinopathy has been described as the most common overuse injury in sports medicine. Several treatment modalities such as activity modification, heel lifts, arch supports, stretching exercises, nonsteroidal anti-inflammatories, and eccentric loading are known as standard treatment mostly without proven evidence. After failed conservative therapy, invasive treatment may be considered. Extracorporeal shock wave therapy (ESWT) has been successfully used in soft-tissue pathologies like lateral epicondylitis, plantar fasciitis, tendinopathy of the shoulder and also in bone and skin disorders. Conclusive evidence recommending ESWT as a treatment for Achilles tendinopathy is still lacking. In plantar fasciitis as well as in calcific shoulder tendinopathy shock wave therapy is recently the best evaluated treatment option. This article analysis the evidence based literature of ESWT in chronic Achilles tendinopathy. Recently published data have shown the efficacy of focused and radial extracorporeal shock wave therapy.

    Plantar fasciitis is the most common cause of heel pain. Diverse non-operative treatment options are available. The purpose of this study was to determine if a single platelet-rich-plasma injection at the origin of the plantar fascia in patients with plantar fasciitis gives a functional improvement. Patients with plantar fasciitis and failed conservative treatment were included in this retrospective study. Included patients were sent four questionnaires after platelet-rich-plasma injection. Primary outcome is functional improvement, determined by foot function index in which lower scores correlates with a better foot function. A total of 61 feet in 58 patients were included. The median foot function index before treatment was 69.4 and after treatment 31.8, which is a significant decrease. In 80.3% of the patients the foot function index decreased. Therefore platelet-rich-plasma injection seems to be effective in treatment of patients with plantar fasciitis when conservative treatment failed. PMID:26280973

    Plantar hyperhidrosis, excessive sweating on the soles of feet, can have a significant impact on patients' quality of life and emotional well-being. Hyperhidrosis is divided into primary and secondary categories, depending on the cause of the sweating, with plantar hyperhidrosis typically being primary and idiopathic. There is an overall increased risk of cutaneous infection in the presence of hyperhidrosis, including fungal, bacterial, and viral infections. This article discusses a range of treatment options including topical aluminum chloride, iontophoresis, injectable botulinum toxin A, glycopyrrolate, oxybutynin, laser, and endoscopic lumbar sympathectomy. Lifestyle changes regarding hygiene, shoe gear, insoles, and socks are also discussed. PMID:27215162

    Full Text Available Plantar fasciitis is a very common painful syndrome, but its exact etiology still remains obscure. The diagnosis is essentially clinical, based on history-taking and physical examination. Complementary laboratory tests and imaging examinations may be useful for differential diagnoses. The treatment is essentially conservative, with a high success rate (around 90%. The essence of the conservative treatment is the home-based program of exercises to stretch the plantar fascia. Indications for surgical treatment are only made when the symptoms persist without significant improvement, after at least six months of conservative treatment supervised directly by the doctor.

  5. Re-irradiation for painful heel spur syndrome. Retrospective analysis of 101 heels

    International Nuclear Information System (INIS)

    Painful heel spur syndrome is a common disease with a lifetime prevalence of approximately 10 %. One of the most effective treatment options is radiotherapy. Many authors recommend a second or third series of radiation for recurrent pain and partial or no response to the initial treatment. As the results of re-irradiation have not been systematically analyzed the aim of this study was to document the results of repeated radiation treatment and to identify patients who could benefit from this treatment. The analysis was performed on patients from 2 German radiotherapy institutions and included 101 re-irradiated heels. Pain was documented with the numeric rating scale (NRS) and carried out before and directly after each radiation therapy as well as for the follow-up period of 24 months. The median age of the patients was 56 years with 30.1 % male and 69.9 % female patients. Pain was caused by plantar fasciitis in 72.3 %, Haglund's exostosis in 15.8 % and Achilles tendinitis in 11.9 %. Repeated radiation was indicated because the initial radiotherapy resulted in no response in 35.6 % of patients, partial response in 39.6 % and recurrent pain in 24.8 %. A significant response to re-irradiation could be found. For the whole sample the median NRS pain score was 6 before re-irradiation, 2 after 6 weeks and 0 after 12 and 24 months. Of the patients 73.6 % were free of pain 24 months after re-irradiation. All subgroups, notably those with no response, partial response and recurrent pain had a significant reduction of pain. Re-irradiation of painful heel spur syndrome is an effective and safe treatment. All subgroups showed a good response to re-irradiation for at least 24 months. (orig.)

  6. Anatomical features of plantar aponeurosis: cadaveric study using ultrasonography and magnetic resonance imaging

    International Nuclear Information System (INIS)

    Abnormalities of the plantar aponeurosis are commonly encountered in patients with subcalcaneal heel pain. Understanding normal anatomy is required to accurately diagnose some disorders of the foot. The purpose of our study was to describe the normal anatomy of the plantar aponeurosis, using ultrasonography and MRI with close anatomic correlation in cadavers. After MRI and ultrasonography of 10 cadaveric foot specimens, the thickness of the central and lateral portions of the plantar aponeurosis displayed by imaging studies was measured by three radiologists. One specimen was sectioned in the transverse plane, one in the coronal plane, one in the sagittal plane, and two in a sagittal oblique plane. Normal anatomy was identified and similar measurements of the plantar aponeurosis were also made. An average value was determined and a statistical analysis was accomplished. The calcaneal insertions of the plantar aponeurosis were better visualized than its distal portions with both MRI and ultrasonography. The measurements of the plantar aponeurosis made by three different radiologists were different, but without statistical significance. The average measurements for the central and lateral portions of the plantar aponeurosis with both imaging methods were different from each other because of differences in the morphology of these structures. The values obtained with ultrasonography and MRI, were also different from each other for both the central and lateral portions of the plantar aponeurosis, but with no statistical significance. We have described the detailed anatomy of the plantar aponeurosis with emphasis on the more distal structures that can be visualized with MRI. There was no statistically significant difference between the accuracy of ultrasonography and MRI regarding the measurements of the thickness of the central and lateral portions of the plantar aponeurosis. Knowledge of the normal anatomy of these structures enables the radiologist to identify early

    Plantar fasciopathy is a painful, degenerative condition of the plantar fascia that affects 2 million people annually and has an estimated 10% lifetime prevalence. When both nonoperative and operative management fails, patients have limited therapeutic options. We present a case of an active 47-year-old male runner who was successfully treated with songraphically guided percutaneous ultrasonic fasciotomy after undergoing a prolonged course of nonoperative management and an endoscopic plantar fascia release procedure. Percutaneous ultrasonic fasciotomy may be considered in patients with chronic, refractory plantar fasciopathy, including those for whom a prior operative release procedure has failed. PMID:25857590

    Fifteen centers for orthopaedic treatment of the foot and ankle participated in a prospective randomized trial to compare several nonoperative treatments for proximal plantar fasciitis (heel pain syndrome). Included were 236 patients (160 women and 76 men) who were 16 years of age or older. Most reported duration of symptoms of 6 months or less. Patients with systemic disease, significant musculoskeletal complaints, sciatica, or local nerve entrapment were excluded. We randomized patients prospectively into five different treatment groups. All groups performed Achilles tendon- and plantar fascia-stretching in a similar manner. One group was treated with stretching only. The other four groups stretched and used one of four different shoe inserts, including a silicone heel pad, a felt pad, a rubber heel cup, or a custom-made polypropylene orthotic device. Patients were reevaluated after 8 weeks of treatment. The percentages improved in each group were: (1) silicone insert, 95%; (2) rubber insert, 88%; (3) felt insert, 81%; (4)stretching only, 72%; and (5) custom orthosis, 68%. Combining all the patients who used a prefabricated insert, we found that their improvement rates were higher than those assigned to stretching only (P = 0.022) and those who stretched and used a custom orthosis (P = 0.0074). We conclude that, when used in conjunction with a stretching program, a prefabricated shoe insert is more likely to produce improvement in symptoms as part of the initial treatment of proximal plantar fasciitis than a custom polypropylene orthotic device.

    Plantar vein thrombosis is a rare condition, with only a handful of cases reported in the literature. The cause is unknown; however, the disease has been attributed to prior surgery, trauma, and paraneoplastic conditions. We present a case of a 32-year-old female runner with plantar vein thrombosis diagnosed on contrast-enhanced MRI and confirmed on ultrasound. The symptoms resolved with conservative treatment and evaluation revealed the presence of a prothrombin gene mutation and use of oral contraceptive pills. To our knowledge, this is the first case of plantar vein thrombosis diagnosed initially by MRI. Moreover, this case suggests that plantar vein thrombosis should be considered in patients with hypercoagulable states and plantar foot pain. (orig.)

  13. Ultrasound- versus palpation-guided injection of corticosteroid for plantar fasciitis: a meta-analysis.

    Zonghuan Li

    Full Text Available BACKGROUND: It is controversial whether ultrasound-guided injection of corticosteroid is superior to palpation-guided injection for plantar fasciitis. This meta-analysis was performed to compare the effectiveness of ultrasound-guided and palpation-guided injection of corticosteroid for the treatment of plantar fasciitis. METHODS: Databases (MEDLINE, Cochrane library and EMBASE and reference lists were searched from their establishment to August 30, 2013 for randomized controlled trials (RCTs comparing ultrasound-guided with palpation-guided injection for plantar fasciitis. The Cochrane risk of bias (ROB tool was used to assess the methodological quality. Outcome measurements were visual analogue scale (VAS, tenderness threshold (TT, heel tenderness index (HTI, response rate, plantar fascia thickness (PFT, hypoechogenicity and heel pad thickness (HPT. The statistical analysis was performed with software RevMan 5.2 and Stata 12.0. When I2<50%, the fixed-effects model was adopted. Otherwise the randomized-effects model was adopted. The Grading of Recommendations Assessment, Development and Evaluation (GRADE system was used to assess the quality of evidence. RESULTS: Five RCTs with 149 patients were identified and analyzed. Compared with palpation-guided injection, ultrasound-guided injection was superior with regard to VAS, TT, response rate, PFT and hypoechogenicity. However, there was no statistical significance between the two groups for HPT and HTI. CONCLUSION: Ultrasound-guided injection of corticosteroid tends to be more effective than palpation-guided injection. However, it needs to be confirmed by further research.

  14. Effect of antipronation foot orthosis geometry on compression of heel and arch soft tissues

    2016-09-01

    Full Text Available This study aimed to understand how systematic changes in arch height and two designs of heel wedging affect soft tissues under the foot. Soft tissue thickness under the heel and navicular was measured using ultrasound. Heel pad thickness was measured while subjects were standing on a flat surface and also while they were standing on an orthosis with 4 and 8 degree extrinsic wedges and 4 and 8 mm intrinsic wedges (n = 27. Arch soft tissue thickness was measured when subjects were standing and when standing on an orthosis with –6 mm, standard, and +6 mm increments in arch height (n = 25. Extrinsic and intrinsic heel wedges significantly increased soft tissue thickness under the heel compared with no orthosis. The 4 and 8 degree extrinsic wedges increased tissue thickness by 28.3% and 27.6%, respectively, while the 4 and 8 mm intrinsic wedges increased thickness by 23.0% and 14.6%, respectively. Orthotic arch height significantly affected arch soft tissue thickness. Compared with the no orthosis condition, the –6 mm, standard, and +6 mm arch heights decreased arch tissue thickness by 9.1%, 10.2%, and 11.8%, respectively. This study demonstrates that change in orthotic geometry creates different plantar soft tissue responses that we expect to affect transmission of force to underlying foot bones.

    2009-02-01

    Full Text Available Abstract Background Patients with diabetic polyneuropathy (DPN are often confronted with ulceration of foot soles. Increased plantar pressure under the forefoot has been identified as a major risk factor for ulceration. This study sets out to test the hypothesis that changes in gait characteristics induced by DPN related muscle weakness are the origin of the elevated plantar pressures. Methods Three groups of subjects participated: people diagnosed with diabetes without polyneuropathy (DC, people diagnosed with diabetic polyneuropathy (DPN and healthy, age-matched controls (HC. In all subjects isometric strength of plantar and dorsal flexors was assessed. Moreover, joint moments at ankle, knee and hip joints were determined while walking barefoot at a velocity of 1.4 m/s. Simultaneously plantar pressure patterns were measured. Results Compared to HC-subjects, DPN-participants walked with a significantly increased internal plantar flexor moment at the first half of the stance phase. Also in DPN-subjects the maximal braking and propelling force applied to the floor was decreased. Moreover, in DPN-subjects the ratio of forefoot-to-rear foot plantar pressures was increased. Body-mass normalized strength of dorsal flexors showed a trend to be reduced in people with diabetes, both DC and DPN, compared to HC-subjects. Plantar flexors tended to be less weak in DC compared to HC and in DPN relative to DC. Conclusion The results of this study suggest that adverse plantar pressure patterns are associated with redistribution of joint moments, and a consequent reduced capacity to control forward velocity at heel strike.

    Research has found that the appearance of women's apparel helps increase their attractiveness as rated by men and that men care more about physical features in potential opposite-sex mates. However, the effect of sartorial appearance has received little interest from scientists. In a series of studies, the length of women's shoe heels was examined. A woman confederate wearing black shoes with 0, 5, or 9 cm heels asked men for help in various circumstances. In Study 1, she asked men to respond to a short survey on gender equality. In Study 2, the confederate asked men and women to participate in a survey on local food habit consumption. In Study 3, men and women in the street were observed while walking in back of the female confederate who dropped a glove apparently unaware of her loss. It was found that men's helping behavior increased as soon as heel length increased. However, heel length had no effect on women's helping behavior. It was also found that men spontaneously approached women more quickly when they wore high-heeled shoes (Study 4). Change in gait, foot-size judgment, and misattribution of sexiness and sexual intent were used as possible explanations. PMID:25408499

    In-shoe loading patterns were examined in each foot (back and front) separately during two types of tennis serve [first (or flat) and second (or twist) serve] and two service stance styles [foot-up (back foot is moved forward next to front foot for push-off) and foot-back (feet remain at the same relative level)]. Ten competitive tennis players completed five trials for each type of serve and service stance style in random order. Plantar pressure distribution was recorded using Pedar insoles divided into nine areas for analysis. Mean and peak pressures (+15.2%, P forces (+20.2%, P forces were higher (+17.2%, P < 0.05) under the lesser toes. Relative load was higher on the lateral forefoot (+20.4%, P < 0.05) but lower (-32.5%, P < 0.05) on the medial heel of the front foot with foot-up compared with foot-back stance. Using a foot-up stance, loading of the back foot was higher (+31.8%, P < 0.01) under the lateral mid-foot but lower (-29.9%, P < 0.01) under the medial forefoot. The type of serve and the stance style adopted have a significant effect on foot loading. Such findings might help improve mechanical efficiency of the serve. PMID:20496222

    Full Text Available Plantar fasciitis is a common cause of heel pain. It has been suggested that some acupoints have a specific effect on heel pain. The aim of this study was to determine the efficacy and specificity of acupuncture treatment for plantar fasciitis. Subjects were randomly assigned to the treatment group (n = 28 or control group (n = 25. The treatment group received needling at the acupoint PC 7, which is purported to have a specific effect for heel pain. The control group received needling at the acupoint Hegu (LI 4, which has analgesic properties. Treatment was administered five times a week for 2 weeks, with an identical method of manual needling applied to the two acupoints. The primary outcome measure was morning pain on a 100-point visual analog scale (VAS at one month post-treatment. Secondary outcome measures included a VAS for activity pain, overall pain rating as well as pressure pain threshold using algometry. Significant differences in reduction in pain scores, favoring the treatment group, were seen at one month for morning pain (22.6 ± 4.0 versus 12.0 ± 3.0, mean ± SEM, overall pain (20.3 ± 3.7 versus 9.5 ± 3.6 and pressure pain threshold (145.5 ± 32.9 versus −15.5 ± 39.4. No serious adverse event was observed in either group. The results indicate that acupuncture can provide pain relief to patient with plantar fasciitis, and that PC 7 is a relatively specific acupoint for heel pain.

    2006-01-01

    The effects of hallux limitus on plantar foot pressure and foot kinematics have received limited attention in the literature. Therefore, a study was conducted to assess the effects of limited first metatarsophalangeal joint mobility on plantar foot pressure. It was equally important to identify detection criteria based on plantar pressures and metatarsophalangeal joint kinematics, enabling differentiation between subjects affected by hallux limitus and people with normal hallux function. To further our understanding of the relation between midtarsal collapse and hallux limitus, kinematic variables relating to midtarsal pronation were also included in the study. Two populations of 19 subjects each, one with hallux limitus and the other free of functional abnormalities, were asked to walk at their preferred speed while plantar foot pressures were recorded along with three-dimensional foot kinematics. The presence of hallux limitus, structural or functional, caused peak plantar pressure under the hallux to build up significantly more and at a faster rate than under the first metatarsal head. Additional discriminators for hallux limitus were peak dorsiflexion of the first metatarsophalangeal joint, time to this peak value, peak pressure ratios of the first metatarsal head and the more lateral metatarsal heads, and time to maximal pressure under the fourth and fifth metatarsal heads. Finally, in approximately 20% of the subjects, with and without hallux limitus, midtarsal pronation occurred after heel lift, validating the claim that retrograde midtarsal pronation does occur.

    This study was done to compare the changes in plantar load (weight distribution) and gait patterns before and after tibialis posterior transfer surgery in people affected by leprosy. Changes in gait patterns were observed and proportionate changes in plantar load were quantified using data captured by a baropodometer. All the eight patients who underwent tibialis posterior transfer surgery in 2013 in our hospital were included in the study. In addition to the regular pre-operative and post-operative assessments, the patients also underwent baropodometric evaluation. There was a significant change in plantar load at the heel, lateral border and forefoot. Using the foot pressure scan, it was noted that the progression of the centre of mass (displayed graphically as 'the gait line') was also affected by the altered pattern of weight distribution. This study reiterates the importance of tibialis posterior transfer because: it restores the normal gait pattern of 1, 2, 3 (where 1 is heel strike, 2 is mid foot contact and 3 is forefoot contact) and provides a more uniform distribution of planter load.

    Full Text Available Background and Aims. The exploration of an individualised protocol of radial extracorporeal shock wave therapy (rESWT for plantar fasciopathy, assessing success rates and the recurrence rate over a 1-year period after treatment, is not yet identified in literature. Methods and Results. Between 2006 and 2013, 68 patients (78 heels were assessed for plantar fasciopathy. An individualised rESWT treatment protocol was applied and retrospectively analysed. Heels were analysed for mean number of shock wave impulses, mean pressure, and mean frequency applied. Significant mean pain reductions were assessed through Visual Analogue Scale (VAS after 1-month, 3-month, and 1-year follow-up. Success rates were estimated as the percentage of patients having more than 60% VAS pain decrease at each follow-up. 1-year recurrence rate was estimated. The mean VAS score before treatment at 6.9 reduced to 3.6, 1 month after the last session, and to 2.2 and 0.9, after 3 months and 1 year, respectively. Success rates were estimated at 19% (1 month, 70% (3 months, and 98% (1 year. The 1-year recurrence rate was 8%. Moderate positive Spearman’s rho correlation (r=0.462, p<0.001 was found between pretreatment pain duration and the total number of rESWT sessions applied. Conclusions. Individualised rESWT protocol constitutes a suitable treatment for patients undergoing rESWT for plantar fasciitis.

    Background and Aims. The exploration of an individualised protocol of radial extracorporeal shock wave therapy (rESWT) for plantar fasciopathy, assessing success rates and the recurrence rate over a 1-year period after treatment, is not yet identified in literature. Methods and Results. Between 2006 and 2013, 68 patients (78 heels) were assessed for plantar fasciopathy. An individualised rESWT treatment protocol was applied and retrospectively analysed. Heels were analysed for mean number of shock wave impulses, mean pressure, and mean frequency applied. Significant mean pain reductions were assessed through Visual Analogue Scale (VAS) after 1-month, 3-month, and 1-year follow-up. Success rates were estimated as the percentage of patients having more than 60% VAS pain decrease at each follow-up. 1-year recurrence rate was estimated. The mean VAS score before treatment at 6.9 reduced to 3.6, 1 month after the last session, and to 2.2 and 0.9, after 3 months and 1 year, respectively. Success rates were estimated at 19% (1 month), 70% (3 months), and 98% (1 year). The 1-year recurrence rate was 8%. Moderate positive Spearman's rho correlation (r = 0.462, p plantar fasciitis.

    Heels are susceptible to pressure ulcer (PU) development. Some evidence suggests dressings may provide mechanical cushioning, reduce friction with support, and lower localized internal tissue loading, which together may minimize the risk for heel ulcers (HUs). To examine the effect of dressing application on pressure ulcer prevention, 20 computer simulations were performed. Volumetric exposure of soft tissues to effective and shear strains and stresses, with and without a multilayered foam dressing, were assessed, with the extent of tissue exposure considered as measures of the theoretical risk for PUs. The simulations, conducted using the finite element method, provided the mechanical strain and stress magnitudes and distributions in the weight-bearing tissues of the heel, which were visualized and analyzed post-hoc for comparing diabetic to healthy tissue loads with/without prophylactic dressings and at different foot (plantar flexion) postures. The volumetric exposure of the soft tissues of the heel to elevated strains and stresses was considerably reduced by the presence of the dressing, whether diabetic or nondiabetic tissue conditions existed, and for the entire range of the simulated plantar flexion positions. Further, greater plantar flexion, which occurs with elevation of the head of the bed, reduced the volumetric exposure of subcutaneous fat to increased effective strains and stresses, again, particularly when the dressing was on. Specifically, peak (maximum of raw data) effective strains in the soft tissues of the heel decreased by 14.8% and 13.5% with the use of the dressing for healthy persons and persons with diabetes, respectively. Additionally, volumetric exposures of the soft tissues to large effective strains, defined as exposures to >50% strain, decreased substantially, by at least a factor of 2, with the angle of plantar flexion and with respect to a neutral foot posture. Volumetric exposures to midrange (less than 50%) strains were more mildly

    Full Text Available Plantar fasciitis is the most common cause of heel pain in adults. A novel alternative medical instrument, the miniscalpel-needle (MSN, which is based on an acupuncture needle, has been recently developed in China. The objective of this study was to evaluate the effectiveness of the MSN release treatment versus that of traditional steroid injection for plantar fasciitis. Patients with plantar fasciitis were randomly assigned to 2 groups and followed up for 12 months, with 29 receiving MSN treatment and 25 receiving steroid injection treatment. The results showed that visual analog scale scores for morning pain, active pain, and overall heel pain all were decreased significantly in the MSN group from 1 to 12 months after treatment. In contrast, treatment with steroid injection showed a significant effect only at the 1-month follow-up but not at 6 or 12 months after treatment. Moreover, the MSN group achieved more rapid and sustained improvements than the steroid group throughout the duration of this study. No severe side effects were observed with MSN treatment. Our data suggest that the MSN release treatment is safe and has a significant benefit for plantar fasciitis compared to steroid injection.

    Background Calcodynia is a persistent condition that podiatric surgeons frequently see among their patients,and plantar fasciitis is the main reason for pain.When systematic conservative treatments fail to alleviate these conditions,it requires surgical intervention,mainly plantar fascia release surgery,which used to be an open heel release surgery.This study aimed to investigate whether minimally invasive treatment of the KobyGard system is more safe and effective for plantar fasciitis.Methods From May 2009 to May 2012,a total of nine patients,three males and six females with plantar fasciitis,were treated in the Peking University People's Hospital with minimally invasive instruments,the KobyGard system,for the release of plantar fascia.Three patients,experiencing bilateral calcaneodynia,underwent bilateral surgery.One patient had bilateral calcaneodynia with enthesiopathy of Achilles tendon,and underwent Achilles tendon surgery.Preoperative and postoperative Visual Analogue Scale(VAS),American Orthopaedic Foot and Ankle Society(AOFAS)ankle and hindfoot scores,Roles and Maudsley scores and SF-36 questionnaires were evaluated.Results The nine patients were successfully followed up.The average postoperative follow-up time was 13.2 months and it varied from 2.0 months to 21.0 months.Pre-and postoperative average scores of VAS was 9.3 and 1.9(P<0.001),respectively.Pre-and postoperative average scores of AOFAS hind foot was 36.0 and 82.0(P<0.001),respectively.There was also a statistically significant amelioration in SF-36 scores and the Roles and Maudlesy scores.Eight patients were satisfied with the surgery outcome.Conclusion Minimally invasive surgery treatment of the KobyGard system for plantar fasciitis has the advantages of shorter operation time,ease of operation,and similar satisfaction rates with open surgery,but with smaller surgical incision.

    Full Text Available Knowledge of variation of position of the medial plantar nerve is important for the forefoot surgeon for plantar reconstruction, local injection therapy and an excision of interdigital neuroma. During routine dissection of 50-year-old female cadaver, we found the medial plantar nerve and vessels variably located between plantar aponeurosis and the muscles of the first layer of the sole of the right foot. Due to this variant position, the medial plantar nerve and vessels lose their protection from the muscles of the first layer of the sole of the foot and became vulnerable for compression.

    Painful heel spur syndrome is a common disease with a lifetime prevalence of approximately 10 %. One of the most effective treatment options is radiotherapy. Many authors recommend a second or third series of radiation for recurrent pain and partial or no response to the initial treatment. As the results of re-irradiation have not been systematically analyzed the aim of this study was to document the results of repeated radiation treatment and to identify patients who could benefit from this treatment. The analysis was performed on patients from 2 German radiotherapy institutions and included 101 re-irradiated heels. Pain was documented with the numeric rating scale (NRS) and carried out before and directly after each radiation therapy as well as for the follow-up period of 24 months. The median age of the patients was 56 years with 30.1 % male and 69.9 % female patients. Pain was caused by plantar fasciitis in 72.3 %, Haglund's exostosis in 15.8 % and Achilles tendinitis in 11.9 %. Repeated radiation was indicated because the initial radiotherapy resulted in no response in 35.6 % of patients, partial response in 39.6 % and recurrent pain in 24.8 %. A significant response to re-irradiation could be found. For the whole sample the median NRS pain score was 6 before re-irradiation, 2 after 6 weeks and 0 after 12 and 24 months. Of the patients 73.6 % were free of pain 24 months after re-irradiation. All subgroups, notably those with no response, partial response and recurrent pain had a significant reduction of pain. Re-irradiation of painful heel spur syndrome is an effective and safe treatment. All subgroups showed a good response to re-irradiation for at least 24 months. (orig.)

  14. The role of bone scintigraphy in determining the etiology of heel pain

    International Nuclear Information System (INIS)

    In this study we aimed to determine the role of bone scintigraphy as an objective diagnostic method in patients with heel pain. Sixty-seven heels of 50 of 182 patients with defined features who attended the orthopedics outpatient clinic with heel pain over a 3-year period, were treated with combined methods such as nonsteroidal anti-inflammatory drugs (NSAID) and contrast baths, stretching exercises and changing of footwear habits. A one year follow-up was established. The criteria identified by Wolgin et al. were used in assessing the results of the treatment. Subcalcaneal spur was demonstrated by radiography in 44 of the 67 heels. There were two different imaging patterns observed on three phase bone scintigraphy. Type I imaging pattern: Focal increased activity in the heel region or normal activity on dynamic and the blood pool phases and focal increased activity at the inferior calcaneal surface in the late static phase. Type II imaging pattern: Diffuse increased activity along the plantar fascia in the dynamic and the blood pool phase, and focal increased activity at the inferior calcaneal surface in the late static phase. There were 34 (50.7%) type I and 18 (26.8%) type II imaging patterns on the scans. Type I and type II imaging patterns were described as osseous and fascial respectively. At the final examination, the results for pattern type I were good in 16 patients (66.7%), fair in 6 patients (25%) and poor in 2 patients (8.3%), whereas in pattern type II results were good in 12 patients (80%) and fair in 3 patients (20%). The recurrence frequency was 4.1% and 6.6%, respectively. Subcalcaneal spur was determined in 70.5% of the patients with osseous pathology and 55.5% of the patients with fascial pathology. Based on this result, it can be ascertained that calcaneal spurs develop during the pathological process causing heel pain. Other findings supporting this claim were the differences in symptom periods of the patients with type I and type II imaging

    We compared the plantar pressures generated by walking in leather-soled Oxford-style shoes and by walking in inexpensive running shoes with those generated by walking in thin socks on a hard surface for thirty-nine individuals (thirteen who had diabetes and neuropathy, and thirteen who had diabetes without neuropathy, and thirteen who had neither diabetes nor neuropathy [controls]). Except for two anatomical regions, the plantar pressure associated with the Oxford-style shoes were not different from those associated with walking without shoes. In comparison, the inexpensive running shoes relieved plantar pressure in the forefoot and heel by a mean (and standard deviation) of 31 +/- 9.1 per cent, with the most relief occurring in the feet that had the highest pressures when they were unshod. There were significant reductions in pressure in all regions of the foot except for the midfoot (p leather-soled Oxford-style shoes because of the risk of ulceration due to elevated plantar pressures. Inexpensive running shoes should be viewed as the very minimally acceptable choice for footwear for these individuals if the feet are free of deformity. PMID:8550649

    INTRODUCTION:: Little is understood about the effects of flexor loading on plantar pressure distribution. The goal of the current work is to model flexor muscle loading applied to the distal phalanges in order to study the effect of these loads on plantar normal stress (pressure) beneath the metatarsal head. METHODS:: The finite element model is a two-dimensional, plane strain sagittal section incorporating the second metatarsal, proximal phalanx, and plantar and dorsal soft tissue (Figure 1). The metatarsophalangeal joint is simulated by a nodal hinge that transfers loads and produces reasonable kinematic motion between the articular surfaces of the proximal[Figure: see text] phalanx and metatarsal head. Soft tissues are simulated by a uniform continuum. A single flexor tendon passes over the condyle of the metatarsal heads with sliding contact against intervening soft tissue, and is attached to the distal end of the proximal phalanx. A rigid element at the proximal end is fixed by boundary conditions to simulate reactions at the distal cuneiform joint. Material properties of bone are from published values, one tenth the stiffness of bone is used for the flexor tendon, and the soft tissue continuum is hyperelastic using coefficients obtained from compression of the heel plantar fat pad. A 188 N vertical ground reaction force and a flexor tendon load at a 10 degree angle from the X (horizontal) axis are applied to the model. RESULTS:: Figure 2 shows Y direction normal stress distribution along the plantar surface for two load cases: no load and a 250 N load to the flexor tendon. DISCUSSION:: Bending moments at the proximal metatarsal correspond to values obtained by Sharkey et al. Tension in the flexor tendon served to counter the moment in the metatarsal created by the vertical load, and at the same time, to apply an additional axial load. Under flexor loading, focal plantar pressure shifts toward the proximal phalanx and yields a 60% reduction in peak pressure

    Full Text Available INTRODUCTION: Plantar fasciitis is a common condition causing misery to lot of patients. The etiology and treatment of plantar fasciitis are poorly understood. The results from such treatments vary considerably, and there is no consensus of opinion on the best method. MATERIAL AND METHODS: We conducted a controlled trial in our institute to compare the results of local steroid injections & the use of Extra-corporeal shock wave therapy (ESWT for managing plantar fasciitis. 200 patients with 240 painful heels were evaluated. All patients with moderate to severe heel pain who had already taken ten days of unsatisfactory treatment with oral NSAIDS were divided in two main groups. Group A of 100 patients received 1000 impulses of shock waves in three sessions at weekly interval. In Group B of 100 patients up to three local injections of 40 mg methyl prednisone mixed with 1 ml. of 2% lignocaine were given at biweekly interval. Pain assessment was done using VAS scale and the results were evaluated at six weeks, three months and six months after the completion of the therapy. CONCLUSIONS: There was a significant difference between two groups of patients being treated. The group B patients had significantly greater improvement in pain scale and early return to daily activities

    Full Text Available Objective: ESWT is widely used in the treatment of plantar fascitis. In this study, we aimed to investigate the effect of ESWT on heel pain and symptoms in the short and medium term. We also compared the subcalcaneal spur length and the heel pain severity and examined the effect of the subcalcaneal spur length on the efficiency of ESWT therapy. Methods: The efficiency of ESWT applied to 59 heel of 48 patients compared retrospectively . We used Visual Analog Scale (VAS and Wolgin scale to evaluate the treatment outcomes. We measure the subcalcaneal spurs length of the patients with foot x-ray . Correlation between the VAS scores and the length of subcalcaneal spur were also evaluated. Results: Improvement in VAS in the first week and 3 months after ESWT treatment was statistically significant. There was no correlation between subcalcaneal spur length and the severity of pain. The number of patients in the'' medium, bad'' group decreased while the number of patients in the '' good'' group incresed according to WDS after ESWT treatment. Conclusion: As a result of this study we concluded that ESWT is effective in the treatment of plantar fasciitis in the short and medium term.

    Plantar fasciitis is a common cause of heel pain in adults. Although it is usually a self-limiting condition, the pain may become prolonged and severe enough to cause significant distress and disruption to the patient's daily activities and work. PubMed and Cochrane Central Register of Controlled Trials databases were searched for randomised controlled trials (RCTs) and a total of ten RCTs were selected for evaluation. These RCTs involved the use of either palpation- or ultrasonography-guided corticosteroid injections in patients diagnosed with plantar fasciitis. All placebo-controlled RCTs showed a significant reduction in pain with the use of corticosteroid injections. Some studies also showed that corticosteroid injections yielded better results than other treatment modalities. However, it is evident from these studies that the effects of corticosteroid injections are usually short-term, lasting 4-12 weeks in duration. Complications such as plantar fascia rupture are uncommon, but physicians need to weigh the treatment benefits against such risks. PMID:26311907

    Full Text Available Abstract Background The Root paradigm of foot function continues to underpin the majority of clinical foot biomechanics practice and foot orthotic therapy. There are great number of assumptions in this popular paradigm, most of which have not been thoroughly tested. One component supposes that patterns of plantar pressure and associated hyperkeratosis lesions should be associated with distinct rearfoot, mid foot, first metatarsal and hallux kinematic patterns. Our aim was to investigate the extent to which this was true. Methods Twenty-seven subjects with planter pathological hyperkeratosis were recruited into one of two groups. Group 1 displayed pathological plantar hyperkeratosis only under metatarsal heads 2, 3 and 4 (n = 14. Group 2 displayed pathological plantar hyperkeratosis only under the 1st and 5th metatarsal heads (n = 13. Foot kinematics were measured using reflective markers on the leg, heel, midfoot, first metatarsal and hallux. Results The kinematic data failed to identify distinct differences between these two groups of subjects, however there were several subtle (generally Conclusions There was some evidence of small differences between planter pathological hyperkeratosis groups. Nevertheless, there was too much similarity between the kinematic data displayed in each group to classify them as distinct foot types as the current clinical paradigm proposes.

    To determine the effect of clipless and toe-clipped pedals on plantar foot pressure while cycling. Seven bikers and 11 healthy volunteers were tested on a Giant ATX Team mountain bike, Tekscan Clinical 5.24 F-scan® system with an inner sole pressure sensor, a Tacx Cycle force One Turbo Trainer and a Cateye Mity 8 computerized speedometer were used. The subjects wore Shimano M037 shoes and used a standard clipless and toe-clipped pedal. The seat height was set at 100% of subject's trochanteric height. Plantar pressures were recorded over 12 consecutive crank cycles at a constant speed for each of the power outputs. The videos were analysed to record the pressure exerted at 12 positions on the foot for each variable. Whether there is any dominance of any of the metatarsals, and any difference in plantar pressures between clipped and clipless pedal. There was a significant difference in the pressure at many positions of the foot, but the sites were different for each individual. General regression analysis indicated that pedal type had a statistically significant effect on plantar pressure at the sites of 1(st) metatarsal (p=0.042), 3(rd) metatarsal (p<0.001), 5(th) metatarsal (<0.001), 2(nd) (p=0.018) and 5(th) toe (p<0.001), lateral midfoot (p<0.001) and central heel (p<0.001) areas. Clipless pedals produce higher pressures which are more spread across the foot than toe-clipped pedals. This may have implications for their use in the prevention and/or management of overuse injuries in the knee and foot. PMID:23738240

    Haglund's deformity is a symptomatic posterosuperior deformity of the heel. The lateral radiograph of the ankle will show a prominent, large, posterosuperior part of the calcaneus, which can be measured using the Fowler and Philips angle (FPA, the angle between the posterior and plantar surface of the calcaneus) and the calcaneal pitch angle (CPA, the angle between the sole of the foot and the plantar part of the calcaneus). Although these angles are commonly used, these radiographic angle measurements have never shown a relationship with Haglund's deformity. In 78 patients (51% male) with symptomatic Haglund's deformity and a control group of 100 patients (41% male) with no heel complaints, we measured the FPA and CPA on weightbearing lateral radiographs of the foot. Using an unpaired t tests, no significant difference was found between the 2 groups in the FPA (p = .40). We measured a significant difference in the CPA between the Haglund group and the control group (p = .014). Subgroup analysis showed that this difference was mainly found in females (p Haglund's deformity will have a greater CPA than will females without Haglund's deformity. The CPA showed a difference between the Haglund and non-Haglund groups, although mainly in females. Although the evidence from our study is limited, it would be interesting to study the CPA further, because it implicates the verticalization of the calcaneus. This change in position results in extra traction on the Achilles tendon and can eventually cause tendinitis and bursitis. Radiographic measurement should be used as an auxiliary tool. If the calcaneus tends to change position, it would be interesting to understand this process, which could eventually lead to improvement in the treatment of Haglund's deformity. PMID:25179453

    Full Text Available Relevance: Plantar fasciitis, the most common cause of heel pain, is due to repetitive strain injury to the medial arch and the heel, causing functional disabilities. Any biomechanical alteration in the lower extremity has its effect on plantar fascia. Kaltenborn mobilization techniques have been proved effective in improving the range of motion of the affected joints. There is a need to evaluate these techniques in plantar fasciitis by treating whole lower extremity. Participants: 20 subjects with the mean age (23.80±2.71 with primary heel pain are recruited in the study. Method: Subjects of randomized controlled trial were randomly allocated into two groups, Group A (n=10 received therapeutic ultrasound, stretching’s and exercises and Group B ( n=10 received therapeutic ultra sound, Kaltenborn mobilizations to the affected joints of lower extremity, stretching and exercises. The outcome measures are visual analogue scale ( VAS , foot function index ( FFI and range of motion measured by Goniometer assessed on day 1 pre-treatment and day 12 post treatment. Analysis: It was done using Mann Whitney U test and Wilcoxon matched pairs test using SPSS software. Results: The intra-group mean differences in pre and post values for group-A are 1.80±2.39, 2.50±2.64, 3.40±1.84, and 19.75±8.16 for ankle dorsiflexion, plantarflexion, VAS and FFI respectively, and in group-B are 1.00±2.11, 10.50±8.32, 4.70±0.67and 28.07±8.26 for ankle dorsiflexion, plantarflexion, VAS and FFI respectively. The intra-group comparison had shown statistical significance with p<0.05 and whereas in between comparison group-B had shown better improvement than group-A. Conclusion: Kaltenborn mobilizations along with therapeutic ultrasound, stretches and exercises have shown better improvement compared to the control group.

    Full Text Available Foot plantar pressure is the pressure field that acts between the foot and the support surface during everyday locomotor activities. Information derived from such pressure measures is important in gait and posture research for diagnosing lower limb problems, footwear design, sport biomechanics, injury prevention and other applications. This paper reviews foot plantar sensors characteristics as reported in the literature in addition to foot plantar pressure measurement systems applied to a variety of research problems. Strengths and limitations of current systems are discussed and a wireless foot plantar pressure system is proposed suitable for measuring high pressure distributions under the foot with high accuracy and reliability. The novel system is based on highly linear pressure sensors with no hysteresis.

Patients and Methods: 71 women and 46 men were irradiated on 136 painful heel spurs in one (n = 104) or two radiation series (n = 13). The painful spurs were located either at the plantar (n = 94), dorsal (n = 5) or bilateral heel (n = 18). 82 patients had prior treatments, in 35 patients RT was the primary treatment. Low-dose RT was performed twice a week with one 6-MV photon field. Ten fractions of 0.5 Gy were applied to a total dose of 5 Gy. Evaluation was done on completion and during follow-up using the four-scale von Pannewitz score. Results: On completion of RT, 27 patients were free of pain, 40 were much improved, 31 reported slight improvement, and 19 experienced no change. After a mean follow-up of 20 months, 75 out of 100 patients were free of pain, twelve had marked and three some improvement. Ten patients reported no change of symptoms. Mean duration of pain before RT was 6 months. RT applied {<=} 6 months after the onset of clinical symptoms resulted in improvement in 94%. By contrast, an interval of > 6 months until the initiation of RT resulted in only 73% of patients with clinical improvement. Conclusion: Low-dose RT reveals a benefit in > 80% of the patients. RT should start during the first 6 months of symptoms. Prospective clinical studies with validated symptom scores should be conducted to assess optimal dose and fractionation scheme of RT. (orig.)

    A combined experimental and numerical approach is used to investigate the interaction phenomena occurring between foot and footwear during the heel strike phase of the gait. Two force platforms are utilised to evaluate the ground reaction forces of a subject in bare and shod walking. The reaction forces obtained from the experimental tests are assumed as loading conditions for the numerical analyses using three dimensional models of the heel region and of the running shoe. The heel pad region, as fat and skin tissues, is described by visco-hyperelastic and fibre-reinforced hyperelastic formulations respectively and bone region by a linear orthotropic formulation. Different elastomeric foams are considered with regard to the outsole, the midsole and the insole layers. The mechanical properties are described by a hyperfoam formulation. The evaluation of the mechanical behaviour of the heel pad tissues at the heel strike in bare and shod conditions is performed considering different combinations of materials for midsole and insole layers. Results allow for the definition of the influence of different material characteristics on the mechanical response of the heel pad region, in particular showing the compressive stress differentiation in the bare and shod conditions.

    Plantar Region of Interest (ROI) detection is important for the early diagnosis and treatment of morphologic defects of the foot and foot bionic research.Conventional methods have employed complex procedures and expensive instruments which prohibit their widespread use in healthcare.In this paper an automatic plantar ROIs detection method using a customized low-cost pressure acquisition device is proposed.Plantar pressure data and 3D motion capture data were collected from 28subjects (14 healthy subjects and 14 subjects with hallux valgus).The maximal inter-frame difference during the stance phase was calculated.Consequently,the ROIs were defined by the first-order difference in combination with prior anatomic knowledge.The anatomic locations were determined by the maximal inter-frame difference and second maximal inter-frame difference,which nearly coincided.Our system can achieve average recognition accuracies of 92.90%,89.30%,89.30%,92.90%,92.90%,and 89.30% for plantar ROIs hallux and metatarsi Ⅰ-Ⅴ,respectively,as compared with the annotations using the 3Dmotion capture system.The maximal difference of metatarsus heads Ⅱ-Ⅴ,and the impulse of the medial and lateral heel features made a significant contribution to the classification of hallux valgus and healthy subjects with ≥ 80% sensitivity and specificity.Furthermore,the plantar pressure acquisition system is portable and convenient to use,thus can be used in home- or community-based healthcare applications.

    Objective To identify the exact origin and insertion of plantar aponeurosis and the anatomic relationship of calcaneal spur to plantar aponeurosis. Methods Fourteen specimen of feet were dissected and radiographed. Three fetus feet were observed histologically. Sonographic evaluation was carried out on 20 normal adults and 52 patients with plantar fasciitis. Results (1) Anatomic observation found that plantar aponeurosis was located under the medial process of caleaneus but not attached to it, and proximally attached to the plantar aspect of calcaneal tuborosity. The insertion (origin) of plantar aponeurosis was not a point but a face. Posteriorly the plantar aponeurosis and fascia of Archlles heel were fused or transmigrated together,entirely covered and attached very coherently to the plantar and posterior aspect of calcaneal tuborosity. (2) Histological observation of heel of fetuses found plantar aponeurosis and fascia of Arehlles heel were eosinophil band-like structure. Both continued at the plantar and posterior aspect of calcaneus and attached closely to bone at this area. There were no significant demarcation between them. (3) Sonographic evaluation:normal plantar aponeurosis showed a thin band-like echo, its orgin attached to entire plantar aspect of calcaneal tuberosity and continued with fascia coming posteriorly from Archlles heel. No distinct boundary existed between these two fascias. When plantar fasciitis occurred, the orgin of plantar aponeurosis thickened significantly,this phenomenon could be detected in wholly plantar aspect of calcaneal tuberrosity. The heel spur didn't located within plantar aponeurosis. Conclusions Plantar aponeurosis orginates from entire plantar aspect of cancaneal tuberosity. Heel spur oeeures in the orgin of the intrinsic musculature, such as flexor digitorum brevis,and doesn't locate within plantar aponeurosis.%目的 研究跖腱膜起点的确切部位及其与跟骨骨刺的关系.方法 对14只足标

    A study on the effect of sectioning the plantar fascia on the range of motion at the first metatarsophalangeal joint is presented. Dorsiflexion and plantarflexion range-of-motion data from 18 patients who had no first metatarsophalangeal joint pathology and had undergone an in-step plantar fasciotomy for recalcitrant plantar fasciitis were analyzed. The average increase in dorsiflexion of the first metatarsophalangeal joint after plantar fascia release was 9.8 degrees, which represented a statistically significant increase using a paired t-test. Thus release of the plantar fascia can be considered a potential adjunct to hallux limitus surgery. PMID:12438498

    Defects of the heel can be difficult to treat because they require a thin, sensate, soft-tissue cover. The lateral calcaneal flap can provide this type of reconstruction in selected patients. A 27-year-old man had a painful defect in a grafted heel that prevented him from working. A satisfactory painless heel was provided by resurfacing the area with a lateral calcaneal flap. The donor defect was minimized by interfascicular dissection of the sural nerve. PMID:8199942

    The purpose of this study was to evaluate differences in dynamic plantar pressure distribution between older people with and without radiographically confirmed osteoarthritis (OA) of the first metatarsophalangeal joint (first MPJ) of the foot. Dynamic plantar pressure recordings using the TekScan MatScan system were obtained during barefoot level walking in 40 older participants; 20 with radiographically confirmed OA of the first MPJ displaying less than 55 degrees of passive dorsiflexion, and 20 with no evidence of OA in the first MPJ displaying greater than 55 degrees of passive dorsiflexion. Group comparisons between the variables maximum force and peak pressure were made for seven different regions underneath the right foot (heel, midfoot, first MPJ, second MPJ, third to fifth MPJs, hallux, and lesser toes). Compared to the control group, participants with OA of the first MPJ exhibited 34% greater maximum force (7.9 +/- 2.5 vs. 5.9 +/- 1.7 kg, p = 0.005) and 23% higher peak pressure (1.6 +/- 0.3 vs. 1.3 +/- 0.3 kg/cm(2), p = 0.001) under the hallux. Similar results were also found under the lesser toes with 43% greater maximum force (5.0 +/- 1.9 vs. 3.5 +/- 1.4 kg; p = 0.006) and 29% higher peak pressure (0.9 +/- 0.2 vs. 0.7 +/- 0.2 kg/cm(2), p = 0.018). No significant differences were found to exist between groups for any other plantar region. These findings indicate that OA of the first MPJ is associated with significant changes in load-bearing function of the foot, which may contribute to the development of secondary pathological changes associated with the condition, such as plantar callus formation and hyperextension of the hallux interphalangeal joint.

    Full Text Available This article investigates the relationship between the use of high heels, personality traits, and fashion consciousness of adult women. The theory of consumer behavior states that the personality of the consumer is a psychological factor that affects consumer decisions, as well as the attitude towards fashion. A survey with 83 women was conducted with two questionnaires. One questionnaire was about fashion consciousness and the use of high heels, and the other utilized the HumanGuide test. The analysis used univariate and multivariate techniques with the aid of SPSS software and Partial Least Squares. The results indicate that 60% of respondents feel pain when wearing high heels. Although designers indicate that a high heel height is above 8 cm, this research indicates that women consider a high heel from 5 cm. Only 27.3% of the responders over 50 years of age use high heels over 8.5 cm. The HumanGuide proved to be useful for Marketing in the sense that the respondents had no difficulty in answering the questions. The use of high heels is mostly explained by fashion consciousness. The most influential factor was the stability of personality, individuals described as conservative, traditional, economical, stable, cautious, steady, and serious. Thus, it appears that these respondents wear high heels because they are related to an elegant traditional dress.DOI: 10.5585/remark.v12i2.2563

  18. Recovery of plutonium from electrorefining anode heels at Savannah River

    International Nuclear Information System (INIS)

    In a joint effort, the Savannah River Laboratory (SRL), Savannah River Plant (SRP), and the Rocky Flats Plant (RFP) have developed two processes to recover plutonium from electrorefining anode heel residues. Aqueous dissolution of anode heel metal was demonstrated at SRL on a laboratory scale and on a larger pilot scale using either sulfamic acid or nitric acid-hydrazine-fluoride solutions. This direct anode heel metal dissolution requires the use of a geometrically favorable dissolver. The second process developed involves first diluting the plutonium in the anode heel residues by alloying with aluminum. The alloyed anode heel plutonium can then be dissolved using a nitric acid-fluoride-mercury(II) solution in large non-geometrically favorable equipment where nuclear safety is ensured by concentration control

    Calcaneal quantitative ultrasound can be used to predict osteoporotic fracture risk, but its ability to monitor therapy is unclear possibly because of its limited precision. We developed a quantitative ultrasound device (foot ultrasound scanner) that measures the speed of sound at the heel...... with the aim of minimizing common error sources like the position and penetration angle of the ultrasound beam, as well as the soft tissue temperature. To achieve these objectives, we used a receiver array, mechanics to adjust the beam direction and a foot temperature sensor. In a group of 60 volunteers, short......-term precision was evaluated for the foot ultrasound scanner and a commercial device (Achilles Insight, GE Medical, Fairfield, CT, USA). In a subgroup of 20 subjects, mid-term precision (1-mo follow-up) was obtained. Compared with measurement of the speed of sound with the Achilles Insight, measurement...

    Full Text Available Aim: Crush injuries of the foot are often associated with partial or complete degloving of the heel pad. The purpose of this study is to present an algorithm for the management of various types of heel pad avulsion injuries, including hyperbaric oxygen (HBO therapy in the treatment regimen. Methods: We present a prospective study of 27 patients with various types of heel pad avulsion managed in our institution from December 2012 to June 2013. Heel pad avulsion injuries were classified according to the angiosomal pattern. Partial or complete avulsions were classified and treated accordingly. HBO therapy was administered postoperatively. The postoperative period, hospital course, and follow-up were documented in patients with heel pad avulsion injuries. Results: Of 27 patients, 20 cases presented with partial avulsion and 7 cases were complete avulsion. Of 20 cases of partial avulsion, one of the flaps was anchored with K-wire. Nineteen cases of partial heel pad avulsion were managed by suturing. Eight patients out of 20 required skin grafting as a secondary procedure at a later date. Out of 7 cases of complete avulsion, one was managed by full-thickness skin grafting, one case by reverse sural artery flap coverage, and four cases were managed by free tissue transfer. No flap revisions were required, and no complications were experienced for the transferred flaps. Conclusion: HBO therapy may be a useful adjunct in the treatment of heel pad avulsion injuries.

    Soft tissue injuries, such as anterior cruciate ligament rupture, ankle sprain and foot skin problems, frequently occur during cutting maneuvers. These injuries are often regarded as associated with abnormal joint torque and interfacial friction caused by excessive external and in-shoe shear forces. This study simultaneously investigated the dynamic in-shoe localized plantar pressure and shear stress during lateral shuffling and 45° sidestep cutting maneuvers. Tri-axial force transducers were affixed at the first and second metatarsal heads, lateral forefoot, and heel regions in the midsole of a basketball shoe. Seventeen basketball players executed both cutting maneuvers with maximum efforts. Lateral shuffling cutting had a larger mediolateral braking force than 45° sidestep cutting. This large braking force was concentrated at the first metatarsal head, as indicated by its maximum medial shear stress (312.2 ± 157.0 kPa). During propulsion phase, peak shear stress occurred at the second metatarsal head (271.3 ± 124.3 kPa). Compared with lateral shuffling cutting, 45° sidestep cutting produced larger peak propulsion shear stress (463.0 ± 272.6 kPa) but smaller peak braking shear stress (184.8 ± 181.7 kPa), of which both were found at the first metatarsal head. During both cutting maneuvers, maximum medial and posterior shear stress occurred at the first metatarsal head, whereas maximum pressure occurred at the second metatarsal head. The first and second metatarsal heads sustained relatively high pressure and shear stress and were expected to be susceptible to plantar tissue discomfort or injury. Due to different stress distribution, distinct pressure and shear cushioning mechanisms in basketball footwear might be considered over different foot regions. PMID:25468303

    To determine the association of atrophy of the abductor digiti minimi muscle (ADMA), an MRI manifestation of chronic compression of the inferior calcaneal nerve suggesting the clinical diagnosis of Baxter's neuropathy, with MRI markers of potential etiologies, including calcaneal spur formation, plantar fasciitis, calcaneal edema, Achilles tendinosis and posterior tibial tendon dysfunction (PTTD). Prevalence of calcaneal spur formation, plantar fasciitis, calcaneal edema, Achilles tendinosis and PTTD was assessed retrospectively on 100 MRI studies with ADMA and 100 MRI studies without ADMA. Patients ranged in age from 10-92 years. Pearson chi-square analyses and Fisher's exact test were used to compare prevalence of the above findings in patients with and without ADMA. Logistic regression was used to determine which variables were significantly associated with ADMA. Among patients with ADMA, there was significantly greater age (57.2 years vs 40.8 years, p < 0.001), presence of Achilles tendinosis (22.0% vs 3.0%, P<0.001), calcaneal edema (15.0% vs 3.0%, P = 0.005), calcaneal spur (48.0% vs 7.0%, P < 0.001), plantar fasciitis (52.5% vs 11.0%, P<0.001), and PTTD (32.0% vs 11.0%, P<0.001). After multivariate logistic regression analysis, only age [odds ratio (OR) 1.06, 95% confidence interval (CI) 1.03, 1.09], calcaneal spur (OR 3.60, 95% CI 1.28, 10.17), and plantar fasciitis (OR 3.35, 95% CI 1.31, 8.56) remained significant. Advancing age, calcaneal spur, and plantar fasciitis are significantly associated with ADMA. Their high odds ratios support the notion of a possible etiologic role for calcaneal spur and plantar fasciitis in the progression to Baxter's neuropathy. (orig.)

    We used kinematic, kinetic and EMG analysis to compare the spontaneous heel-contact gait patterns of 13 children classified as habitual toe walkers (HTWs) and age-matched controls. In the HTWs, the incidence of spontaneous heel-contact strides during a single recording session ranged from 15% to 92%, with no correlation with age, passive ankle joint excursion, walking speed and trial order. Hallmarks of the heel-contact strides were premature heel-rise, reversal of the second rocker, relative shortening of the loading response and anticipation and enhancement of the electromyographic (EMG) activity normally observed in the triceps surae (TS) during the first half of the stance phase. This variant of the locomotor program is different from the walking patterns observed in normally developing toddlers and children with cerebral palsy (CP). It does not necessarily reflect a functional adaptation to changes in the rheological properties of the muscle-tendon complex. PMID:15760747

  7. Cryotherapy usage to treat plantar warts

    International Nuclear Information System (INIS)

    Treating dermatosis with liquid nitrogen as cryogen (substance generating cold) allows cellular destruction in more than 5 mm depth, making it indispensable to use it treating cutaneous cancers; besides that, it is cheap, easy to conserve and manage, and it is not considered flammable or toxic. Its applying retains the growth factor inside the injury, the collagen is not damaged as it is in burning by hot, there is not almost injury contraction, the perineurium is not altered, and when the tissue necrosis takes place, it retains tissue necrosis factor, helping to increase the necrosis of tissues. Taking into account the high incidence of dermatosis that can be treated with cryogen, in our consultation; we decided to generalize this treatment at the Provincial Interior Ministry Clinic. Plantar warts represent a big percent, limiting our patients in developing their working activities. This cutaneous viral disease is favored by the patients' systemic immunodepressions, hyperhidrosis and podalic disturbances. We selected the patients assisting to our extern al consultation with plantar wart clinical diagnosis in the period from September 2006 to September 2007. They signed an act of informed consent where the possible side effects are explained. Liquid nitrogen was applied with cotton applicators once a week after mechanical reduction. We made a clinical evolving evaluation fortnightly during the treatment, according to the elements and clinical characteristics referred by the patient, and proved by the physical examination carried out by the main investigator, because of the likelihood of short and long time side effects. This investigation demonstrated that cryotherapy is efficacious in treating plantar warts, since all the patients were healed in a short time period, most of them without side effects

    Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc. PMID:27079090

    Various surgical treatment procedures for plantar fasciitis, such as open surgery, percutaneous release, and endoscopic surgery, exist. Skin trouble, nerve disturbance, infection, and persistent pain associated with prolonged recovery time are complications of open surgery. Endoscopic partial plantar fascia release offers the surgeon clear visualization of the anatomy at the surgical site. However, the primary medial portal and portal tract used for this technique have been shown to be in close proximity to the posterior tibial nerves and their branches, and there is always the risk of nerve damage by introducing the endoscope deep to the plantar fascia. By performing endoscopic partial plantar fascia release under ultrasound assistance, we could dynamically visualize the direction of the endoscope and instrument introduction, thus preventing nerve damage from inadvertent insertion deep to the fascia. Full-thickness release of the plantar fascia at the ideal position could also be confirmed under ultrasound imaging. We discuss the technique for this new procedure. PMID:24265989

    Full Text Available The etiology of plantar fasciitis (PF has been related to several risk factors, but the magnitude of the plantar load is the most commonly described factor. Although PF is the third most-common injury in runners, only two studies have investigated this factor in runners, and their results are still inconclusive regarding the injury stage.Analyze and compare the plantar loads and vertical loading rate during running of runners in the acute stage of PF to those in the chronic stage of the injury in relation to healthy runners.Forty-five runners with unilateral PF (30 acute and 15 chronic and 30 healthy control runners were evaluated while running at 12 km/h for 40 meters wearing standardized running shoes and Pedar-X insoles. The contact area and time, maximum force, and force-time integral over the rearfoot, midfoot, and forefoot were recorded and the loading rate (20-80% of the first vertical peak was calculated. Groups were compared by ANOVAs (p<0.05.Maximum force and force-time integral over the rearfoot and the loading rate was higher in runners with PF (acute and chronic compared with controls (p<0.01. Runners with PF in the acute stage showed lower loading rate and maximum force over the rearfoot compared to runners in the chronic stage (p<0.01.Runners with PF showed different dynamic patterns of plantar loads during running over the rearfoot area depending on the injury stage (acute or chronic. In the acute stage of PF, runners presented lower loading rate and forces over the rearfoot, possibly due to dynamic mechanisms related to pain protection of the calcaneal area.

    Diabetic foot ulcers are caused by moderate repetitive plantar stresses in the presence of peripheral neuropathy. In severe cases, the development of these foot ulcers can lead to lower extremity amputations. Plantar pressure measurements have been considered a capable predictor of ulceration sites in the past, but some investigations have pointed out inconsistencies when solely relying on this method. The other component of ground reaction forces/stresses, shear, has been understudied due to a lack of adequate equipment. Recent articles reported the potential clinical significance of shear in diabetic ulcer etiology. With the lack of adequate tools, plantar temperature has been used as an alternative method for determining plantar triaxial loading and/or shear. However, this method has not been previously validated. The purpose of this study was to analyze the potential association between exercise-induced plantar temperature increase and plantar stresses. Thirteen healthy individuals walked on a treadmill for 10 minutes at 3.2km/h. Pre and post-exercise temperature profiles were obtained with a thermal camera. Plantar triaxial stresses were quantified with a custom-built stress plate. A statistically significant correlation was observed between peak shear stress (PSS) and temperature increase (r=0.78), but not between peak resultant stress (PRS) and temperature increase (r=0.46). Plantar temperature increase could predict the location of PSS and PRS in 23% and 39% of the subjects, respectively. Only a moderate linear relationship was established between triaxial plantar stresses and walking-induced temperature increase. Future research will investigate the value of nonlinear models in predicting plantar loading through foot temperature. PMID:25446272

    Diabetes-related neuropathic ulcers located at the plantar aspect of the hallux interphalangeal joint are often chronic or recurrent and frequently become complicated by osteomyelitis. Once infected, treatment will typically involve hallux amputation. Although intended as a definitive procedure, amputation of the first toe is not desirable from a cosmetic or functional standpoint and often leads to transfer ulcers at adjacent locations of the foot. Reconstructive wound surgery, combined with limited bone resection, is possible if the infection is caught early before the local tissue and bone have become necrotic. In addition to neuropathy, biomechanical issues, including ankle equinus, hallux limitus, hallux extensus, and hallux valgus, predispose patients with diabetes mellitus to developing plantar hallux ulcers. We commonly employ a proximal based unilobed plantar rotational flap combined with hallux interphalangeal joint arthroplasty as an alternative to hallux amputation. We present a typical case with long-term follow-up to highlight our flap protocol, including patient selection criteria, flap design, surgical technique, bone resection and biopsy pearls, staging timeline, and a typical postoperative course. Periodic follow-up during the next 72 months for unrelated conditions allowed long-term monitoring with no recurrence of osteomyelitis or subsequent amputation. The foot remained ulcer free 6 years later. The benefits of this surgical approach include complete excision of the ulcer, adequate exposure for bone resection, early bone biopsy before the spread of infection or necrosis of local tissue, flap coverage with viable soft tissue, and partial offloading of mechanical pressure at the plantar interphalangeal joint.

    Full Text Available Abstract Background If conservative treatment for chronic plantar fasciitis fails, often a corticosteroid injection is given. Corticosteroid injection gives temporarily pain reduction, but no healing. Blood platelets initiate the natural healing rate. GPS® gives an eightfold concentrate platelets of patients own blood. Injection of these platelets in the attachment of the fascia to the os calcis might induce a healing rate. Methods and design A randomized controlled multi centre trial will be performed. The study population consists of 120 patients of 18 years and older. Patients with chronic plantar fasciitis will be allocated randomly to have a steroid injection or an autologous platelet concentrate injections. Data will be collected before the procedure, 4,8,12,26 weeks and 1 year after the procedure. The main outcome measures of this study are pain and function measured with questionnaires. Conclusion Recent literature show positive effects for the treatment of tendinosis with autologous platelet injections. The forthcoming trial will compare treatment for chronic plantar fasciitis with a steroid injection versus an autologous platelet injection. Our results will be published as soon as they become available. Trial Registration Trial registration number: http://www.clinicaltrials.gov NCT00758641.

    Full Text Available Several studies have already reported that specific foot/ankle muscle reinforcement strategies induced strength and joint position sense performance enhancement. Nevertheless the effects of such protocols on sprint performance and plantar loading distribution have not been addressed yet. The objective of the study is to investigate the influence of a 5-wk foot/ankle strength training program on plantar loading characteristics during sprinting in adolescent males. Sixteen adolescent male athletes of a national training academy were randomly assigned to either a combined foot/ankle electromyostimulation and resistance training (FAST or a control (C group. FAST consisted of foot medial arch and extrinsic ankle muscles reinforcement exercises, whereas C maintained their usual training routine. Before and after training, in-shoe loading patterns were measured during 30-m running sprints using pressure sensitive insoles (right foot and divided into nine regions for analysis. Although sprint times remained unchanged in both groups from pre- to post- training (3.90 ± 0.32 vs. 3.98 ± 0.46 s in FAST and 3.83 ± 0.42 vs. 3.81 ± 0.44 s in C, changes in force and pressure appeared from heel to forefoot between FAST and C. In FAST, mean pressure and force increased in the lateral heel area from pre- to post- training (67.1 ± 44.1 vs. 82.9 ± 28.6 kPa [p = 0.06]; 25.5 ± 17.8 vs. 34.1 ± 14.3 N [p = 0.05] and did not change in the medial forefoot (151.0 ± 23.2 vs. 146.1 ± 30.0 kPa; 142.1 ± 29.4 vs. 136.0 ± 33.8; NS. Mean area increased in FAST under the lateral heel from pre- to post- (4.5 ± 1.3 vs. 5.7 ± 1.6 cm2 [p < 0.05] and remained unchanged in C (5.5 ± 2.8 vs. 5.0 ± 3.0 cm2. FAST program induced significant promising lateral and unwanted posterior transfer of the plantar loads without affecting significantly sprinting performance

    Objective To investigate the relationship between the medial calcaneal nerve (MCN) and neurogenic painful heel syndrome (NPHS), and provide anatomical evidence for study, diagnosis and therapy. Methods 32 formalin-fixed adult lower limb specimens were used in the study. MCN was dissected for demonstrating the origin, course, branches and the distribution. Results 41.42% of MCN originated from the trunk of tibial nerve, however, 28.57% originated from the bifurcation site of tibial nerve, 18.57% from the medial plantar nerve, and 11.42% from the lateral plantar nerve. The distance from the origin of MCN to the middle point between the lowest margin of the medial malleolus and the medial process of calcaneal tuberosity was about (30.22± 15.34)mm. MCN distributed to medial heel, the skin of footplate, and soft tissue of heel, after passing through flexor retinaculum. Conclusions MCN maybe compressed in the ankle canal, or the calcaneal tunnel, or at the site of passing from the flexor retinaculum, which are probably related to the occurrence of the plantar fasciitis and heel pain.%目的 探讨跟内侧神经的局部解剖特点及其与神经源性跟痛症的关系,为临床诊断治疗提供解剖学依据.方法 32侧防腐成人尸体下肢标本,解剖观察跟内侧神经的起源、分支、走行和分布特点.结果 跟内侧神经41.42%起源于胫神经,28.57%起源于胫神经分叉处,18.57%起源于足底内侧神经,11.42%起源于足底外侧神经.起点距O点(内踝尖最下缘与跟骨结节内侧突连线中点)(30.22±15.34)mm.跟内侧神经穿出屈肌支持带后分布于足跟内侧及跟底的皮肤和跟垫组织.结论 跟内侧神经在踝管内,浅出屈肌支持带处及跟管内可能被卡压;神经卡压或病变可能与足底腱膜炎发生及疼痛有关.

    Full Text Available Abstract Background Previous studies have suggested that increased plantar surface area, associated with pes planus, is a risk factor for the development of lower extremity overuse injuries. The intent of this study was to determine if a single or combination of foot anthropometric measures could be used to predict plantar surface area. Methods Six foot measurements were collected on 155 subjects (97 females, 58 males, mean age 24.5 ± 3.5 years. The measurements as well as one ratio were entered into a stepwise regression analysis to determine the optimal set of measurements associated with total plantar contact area either including or excluding the toe region. The predicted values were used to calculate plantar surface area and were compared to the actual values obtained dynamically using a pressure sensor platform. Results A three variable model was found to describe the relationship between the foot measures/ratio and total plantar contact area (R2 = 0.77, p R2 = 0.76, p Conclusion The results of this study indicate that the clinician can use a combination of simple, reliable, and time efficient foot anthropometric measurements to explain over 75% of the plantar surface contact area, either including or excluding the toe region.

    Full Text Available In the Japanese, Formosan and crab-eating monkeys, the dorsal metatarsal arteries and their lateral distal perforating branches were well developed and supplied, directly or via the catella plantaris distalis, the plantar digital arteries. In the black ape, the plantar digital arteries arose from the medial plantar artery. The plantar metatarsal arteries of these monkeys, including the black ape, arose from the catella plantaris proximalis or deep plantar arch and were classified into the superficial plantar metatarsal (sM, superficial plantar intermetatarsal (sI, deep plantar metatarsal (dM and deep plantar intermetatarsal (dI arteries in relation to the interosseous muscles and metatarsal bones. This classification largely coincides with that of the human hand and foot (Murakami, 1969, 1971 and the monkey hand (Nakai et al., 1987.

    [Purpose] This study aimed to examine the effects of low-dye taping on paretic side plantar pressure in patients with plantar fasciitis. [Subjects] The 30 patients in this study were randomly allocated to a low-dye taping group (n = 15) or a conservative treatment group (n =15). [Methods] Both groups received treatment thrice a week for six weeks. BioRescue was used to measure the weight distribution of the patients' paretic side. [Results] Within-group comparison showed that the posterior weight distribution significantly increased among patients in both groups. However, comparison between the two groups showed that the low-dye taping group's posterior weight distribution was significantly higher than that of the conservative treatment group. [Conclusion] These findings show that the application of low-dye taping is an effective intervention for paretic-side plantar pressure among patients with plantar fasciitis. PMID:26696737

  5. Effect of viscoelastic properties of plantar soft tissues on plantar pressures at the first metatarsal head in diabetics with peripheral neuropathy

    International Nuclear Information System (INIS)

    Diabetic foot ulcers are one of the most serious complications associated with diabetes mellitus. Current research studies have demonstrated that biomechanical alterations of the diabetic foot contribute to the development of foot ulcers. However, the changes of soft tissue biomechanical properties associated with diabetes and its influences on the development of diabetic foot ulcers have not been investigated. The purpose of this study was to investigate the effect of diabetes on the biomechanical properties of plantar soft tissues and the relationship between biomechanical properties and plantar pressure distributions. We used the ultrasound indentation tests to measure force-deformation relationships of plantar soft tissues and calculate the effective Young's modulus and quasi-linear viscoelastic parameters to quantify biomechanical properties of plantar soft tissues. We also measured plantar pressures to calculate peak plantar pressure and plantar pressure gradient. Our results showed that diabetics had a significantly greater effective Young's modulus and initial modulus of quasi-linear viscoelasticity compared to non-diabetics. The plantar pressure gradient and biomechanical properties were significantly correlated. Our findings indicate that diabetes is linked to an increase in viscoelasticity of plantar soft tissues that may contribute to a higher peak plantar pressure and plantar pressure gradient in the diabetic foot.

    Full Text Available Background. Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren` s disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose`s disease or plantar fibromatosis is plantar equivalent of Dupuyten`s disease most often affecting middle- aged and older men, usually bilateral, represented with painless nodule in the medial division of plantar fascia. Case report. We presented a 19-year old adolescent that turned to a plastic surgeon complaining to his small finger contracture. He noticed palmar thickening with nodule over the metacarpophalangeal joint of small finger of his right hand when he was 16 years old. A year later a finger started to band. During physical checkup we noticed plantar nodule that also had his father and grandmother. Magnetic resonance and tumor biopsy confirmed a suspicion on plantar fibromatosis - Ledderhose`s disease. Clinical exam of the hand clearly led to a conclusion that the patient had Dupuytren`s contracture with pretendinous cord over the small finger flexor tendons and lack of extension of proximal interphalangeal (PIP joint. On the extensor side of the PIP joints there were Garrod`s nodes. The patient refused surgical treatment of plantar tumor, but agreed to surgical correction of finger contracture. Conclusion. Despite the fact that Dupuytren`s disease and plantar fibromatosis are diseases of adults, the possibility of conjoint appearance of these forms of fibromatosis in adolescent period of life should be kept in mind especially in patients with strong genetic predisposition.

Due to the pain, the child often limits his/her physical activity level, with a possible negative effect on health and well-being. Although numerous research studies have examined the cause and treatment of heel and Achilles tendon pain in adults, there are no randomized clinical trials on treatment in children and adolescents. Therefore, there is limited evidence for how to treat young athletes with this type of complaint. The purpose of this review was to analyze critically and summarize the literature in regards to the cause and treatment of posterior heel pain in young athletes. The various diagnoses and clinical presentations relating to posterior heel and Achilles tendon pain are discussed. The theory and mechanism behind various recommended treatment strategies are also reviewed in the context of use in the young athlete. In summary, it is important to perform a thorough evaluation of each young athlete with heel pain to determine the appropriate diagnosis and to treat the deficits found and allow for a gradual progression to training. However, the recommendations at this time are based on clinical experience and a few retrospective studies, so further well designed prospective studies with validated outcome measures are urgently needed for the young athlete.Keywords: Sever's disease, apophysitis, tendinitis, tendinopathy, child, adolescent

    In plantar pressure measurement, both peak pressure and pressure time integral are used as variables to assess plantar loading. However, pressure time integral shows a high concordance with peak pressure. Many researchers and clinicians use Novel software (Novel GmbH Inc., Munich, Germany) that calculates this variable as the summation of the products of peak pressure and duration per time sample, which is not a genuine integral of pressure over time. Therefore, an alternative calculation method was introduced. The aim of this study was to explore the relevance of this alternative method, in different populations. Plantar pressure variables were measured in 76 people with diabetic polyneuropathy, 33 diabetic controls without polyneuropathy and 19 healthy subjects. Peak pressure and pressure time integral were obtained using Novel software. The quotient of the genuine force time integral over contact area was obtained as the alternative pressure time integral calculation. This new alternative method correlated less with peak pressure than the pressure time integral as calculated by Novel. The two methods differed significantly and these differences varied between the foot sole areas and between groups. The largest differences were found under the metatarsal heads in the group with diabetic polyneuropathy. From a theoretical perspective, the alternative approach provides a more valid calculation of the pressure time integral. In addition, this study showed that the alternative calculation is of added value, along peak pressure calculation, to interpret adapted plantar pressures patterns in particular in patients at risk for foot ulceration.

    There is a causal relationship between diabetic foot ulceration, elevated plantar pressure, and severe sensory neuropathy. Cushioned footwear intended to relieve plantar pressure is well established for prevention and healing of plantar ulcers. The aim of the present study was to investigate whether pressure relief by means of a running shoe with optimized forefoot pressure damping is comparable to that of a custom-made soft insole placed into an in-depth shoe. The in-shoe pressures were compared to an in-depth shoe with the original cork insole and with a leather-soled Oxford shoe. The maximum reduction of plantar pressure in the running shoe was 47% under the 2nd and 3rd metatarsal heads, 29% at the first metatarsal head, and 32% at the great toe in comparison to the Oxford shoe. This was surpassed only by the custom-made insole, which reduced pressures at the metatarsal heads by 50%. The specially designed running shoe yielded the same pressure relief at the central metatarsal heads as the custom-made insole. Such shoes are likely to be very useful in preventing diabetic foot ulceration in high-risk patients as a comparatively affordable and immediately available device. PMID:9632129

    Full Text Available Abstract Background Plantar hyperkeratotic lesions are common in older people and are associated with pain, mobility impairment and functional limitations. However, little has been documented in relation to the frequency or distribution of these lesions. The aim of this study was to document the occurrence of plantar hyperkeratotic lesions and the patterns in which they occur in a random sample of older people. Methods A medical history questionnaire was administered to a random sample of 301 people living independently in the community (117 men, 184 women aged between 70 and 95 years (mean 77.2, SD 4.9, who also underwent a clinical assessment of foot problems, including the documentation of plantar lesion locations, toe deformities and the presence and severity of hallux valgus. Results Of the 301 participants, 180 (60% had at least one plantar hyperkeratotic lesion. Those with plantar lesions were more likely to be female (χ2 = 18.75, p 2 = 6.15, p vs 36.3 ± 8.4°; t = 2.68, df = 286, p vs 4.8 ± 1.3 hours, t = -2.46, df = 299, p = 0.01. No associations were found between the presence of plantar lesions and body mass index, obesity, foot posture, dominant foot or forefoot pain. A total of 53 different lesions patterns were observed, with the most common lesion pattern being "roll-off" hyperkeratosis on the medial aspect of the 1st metatarsophalangeal joint (MPJ, accounting for 12% of all lesion patterns. "Roll-off" lesions under the 1st MPJ and interphalangeal joint were significantly associated with moderate to severe hallux valgus (p p Conclusion Plantar hyperkeratotic lesions affect 60% of older people and are associated with female gender, hallux valgus, toe deformity, increased ankle flexibility and time spent on feet, but are not associated with obesity, limb dominance, forefoot pain or foot posture.

  14. Retrospective study on radiotherapy efficacy in case of painful heel spur

    International Nuclear Information System (INIS)

    Objective: The effect of radiotherapy in context of a plantar fasciitis in order to reduce pain was evaluated in this retrospective study. Patients and methods: The data of 188 patients who suffered of heel spur pain and who were irradiated in the period from 1994 to 2009 were evaluated in this study. All of them had at least one follow up examination after radiatiotherapy. The mean age amounted to 57 years. 76.5% of the patients were female. All patients described a local pain which was the basis for the indication. 74.4 % of the patients described pain especially under stress. The duration of anamnesis was averaged as follows: 15 % of the patients had pain for some weeks to 3 months, 43 % for 4 to 6 months, 28% even for 7 to 12 months. The period of medical history was longer than 12 months for 12 % of the patients in this study. 122 of 188 patients received orthopedic arch support (shoe inlays) as first therapy method. Most of the patients were irradiated using regular lateral opposing fields with photons of the energy 4 MV and 6 MV of a linear accelerator, applying a total dose of 6Gy in 6 fractions to 1,0Gy twice weekly. Only one patient was irradiated using a Co60 machine. The acquisition of data regarding the effect was performed on the last day of the radiotherapy and in 3 to 6 monthly follow ups. Additionally the doctors who attended the patients beyond the radiotherapy received a special questionnaire about the pain reduction, so that the follow up data could be completed. Results: On the last day of radiotherapy 120/188 patients (63,8%)reported an improvement of pain reduction, 7/188 patients (3,7%) absence of pain. For 52/188 patients (27.6 %) pain remained constant. At the second follow up examination after in the median 100 days the effect of radiotherapy of 165 patients could be evaluated, 43/165 patients (26 %) were pain free, 79/165 patients (47,8 %) reported an obvious pain reduction, and for 33/165 patients there was no pain improvement.

    Full Text Available Complications of diabetes mellitus constitute the most common indications for hospitalization and non-traumatic amputations in the USA. The most important risk factors for the development of diabetic foot ulcerations include the presence of peripheral neuropathy, vasculopathy, limited joint mobility, and pre-existing foot deformities. In our study, 500 diabetic patients treated for plantar forefoot ulcerations were enrolled in a prospective study from 2000 to 2008 at the Federal University of São Paulo, Brazil. Fifty-two patients in the study met the criteria and underwent surgical treatment consisting of percutaneous Achilles tendon lengthening to treat plantar forefoot ulcerations. The postoperative follow-up demonstrated prevention of recurrent foot ulcerations in 92% of these diabetic patients that maintained an improved foot function. In conclusion, our study supports that identification and treatment of ankle equinus in the diabetic population may potentially lead to decreased patient morbidity, including reduced risk for both reulceration, and potential lower extremity amputation.

  18. Heel spur radiotherapy and radiation carcinogenesis risk estimation

    International Nuclear Information System (INIS)

    Radiotherapy is a nonsurgical alternative therapy of painful heel spur patients. Nonetheless, cancer induction is the most important somatic effect of ionizing radiation. This study was designed to evaluate the carcinogenesis risk factor in benign painful heel spur patients treated by radiotherapy. Between 1974 and 1999, a total of 20 patients received mean 8.16 Gy total irradiation dose in two fractions. Thermoluminescent dosimeters (TLD100) were placed on multiple phantom sites in vivo within the irradiated volume to verify irradiation accuracy and carcinogenesis risk factor calculation. The 20 still-alive patients, who had a minimum 5-year and maximum 29-year follow-up (mean 11.9 years), have been evaluated by carcinogenic radiation risk factor on the basis of tissue weighting factors as defined by the International Commission on Radiological Protection Publication 60. Reasonable pain relief has been obtained in all 20 patients. The calculated mean carcinogenesis risk factor is 1.3% for radiation portals in the whole group, and no secondary cancer has been clinically observed. Radiotherapy is an effective treatment modality for relieving pain in calcaneal spur patients. The estimated secondary cancer risk factor for irradiation of this benign lesion is not as high as was feared. (author)

  19. Heel Removal Analysis for Mixing Pumps of Tank 8

    International Nuclear Information System (INIS)

    Computational fluid dynamics methods were used to recommend a slurry pump operational strategy for sludge heel removal in Tank 8. Flow patterns calculated by the model were used to evaluate the performance of various combinations of operating pumps and their orientation. The models focused on removal of the sludge heel located at the east side of Tank 8 using the four existing slurry pumps. The models and calculations were based on prototypic tank geometry and expected normal operating conditions as defined by Waste Removal Closure (WRC) Engineering. The calculated results demonstrated that for pump speeds higher than 1800 rpm and at a 130 inch liquid level, a recommended orientation of the slurry pumps could be provided, based on a minimum sludge suspension velocity of 2.27 ft per sec. Further results showed that the time to reach a steady-state flow pattern was affected by both the tank level and the pump speed. Sensitivity studies showed that for a given pump speed, a higher tank level and a lower pump nozzle elevation would result in better performance in suspending and removing the sludge. The results also showed that the presence of flow obstructions were advantageous for certain pump orientations

    The localized early-stage of Mycosis fungoides (MF) (stage IA-IIA) is usually treated with topical agents, such as nitrogen mustard, steroids, and phototherapy (UVB/PUVA) as first line therapy; response to these initial treatments is usually good. However, hyperkeratotic plantar lesions are clinically rare and have decreased responsiveness to topical agents. For such cases, physicians may consider local radiotherapy. Here, a case of an 18-year-old Korean woman who was treated with three-dimen...

    The aim of the study was to investigate the distribution of net joint moments in the lower extremities during walking on high-heeled shoes compared with barefooted walking at identical speed. Fourteen female subjects walked at 4 km/h across three force platforms while they were filmed by five...... digital video cameras operating at 50 frames/second. Both barefooted walking and walking on high-heeled shoes (heel height: 9 cm) were recorded. Net joint moments were calculated by 3D inverse dynamics. EMG was recorded from eight leg muscles. The knee extensor moment peak in the first half of the stance...... joint abductor moment. Several EMG parameters increased significantly when walking on high-heels. The results indicate a large increase in bone-on-bone forces in the knee joint directly caused by the increased knee joint extensor moment during high-heeled walking, which may explain the observed higher...

  3. Effects of foot posture and heel padding devices on soft tissue deformations under the heel in supine position in males: MRI studies

    2013-11-01

    Full Text Available Heel ulcers (HUs are the second most common pressure ulcers (PUs. Despite the significant morbidity and economic cost associated with HUs, there remains a lack of understanding of the basic pathophysiology of PUs because of limited basic research. There are only sparse data regarding the efficacy of prevention aids such as heel padding devices, and these data are based mainly on epidemiological research rather than biomechanical models and deformation measurements. This study was designed to explore the effects of foot posture and support stiffness properties on soft tissue deformations using magnetic resonance imaging (MRI. Subjects were scanned with and without weight bearing, in neutral external rotation position and in 90 degrees to supporting surface and with different heel padding devices. Tissue strains were calculated for skin, subcutaneous tissue, and effective (total soft tissue. We found skin strains with the foot in external rotation to be significantly greater than when the foot was upright. Heel padding devices have a statistically significant effect on reducing the extent of deformations in both skin and subcutaneous tissues. Furthermore, the design features of heel padding devices have substantial influence on tissue deformations. This study demonstrates how MRI provides convenient, accurate, and quantitative comparison of biomechanical performances of heel padding devices.

    2012-02-01

    Full Text Available Pitted keratolysis is an acquired, superficial bacterial infection of the skin which is characterized by typical malodor and pits in the hyperkeratotic areas of the soles. It is more common in barefooted people in tropical areas, or those who have to wear occlusive shoes, such as soldiers, sailors and athletes. In this study, we evaluated 41 patients who had been diagnosed with plantar pitted keratolysis. The patients were of high socioeconomic status, were office-workers, and most had a university degree. Malodor and plantar hyperhydrosis were the most frequently reported symptoms. The weight-bearing metatarsal parts of the feet were those most affected. Almost half the women in the study gave a history of regular pedicure and foot care in a spa salon. Mean treatment duration was 19 days. All patients were informed about the etiology of the disease, predisposing factors and preventive methods. Recurrences were observed in only 17% of patients during the one year follow-up period. This study emphasizes that even malodorous feet among non-risk city dwellers may be a sign of plantar pitted keratolysis. A study of the real incidence of the disease in a large population-based series is needed.

    2011-05-01

    Wearing high heel shoes has been associated with an increased potential for slips and falls. The association between wearing high heels and the increased potential for slipping suggests that the friction demand while wearing high heels may be greater when compared to wearing low heel shoes. The purpose of this study was to determine if heel height affects utilized friction (uCOF) during walking. A secondary purpose of this study was to compare kinematics at the ankle, knee, and hip that may explain uCOF differences among shoes with varied heel heights. Fifteen healthy women (mean age 24.5±2.5yrs) participated. Subjects walked at self-selected velocity under 3 different shoe conditions that varied in heel height (low: 1.27cm, medium: 6.35cm, and high: 9.53cm). Ground reaction forces (GRFs) were recorded using a force platform (1560Hz). Kinematic data were obtained using an 8 camera motion analysis system (120Hz). Utilized friction was calculated as the ratio of resultant shear force to vertical force. One-way repeated measures ANOVAs were performed to test for differences in peak uCOF, GRFs at peak uCOF and lower extremity joint angles at peak uCOF. On average, peak uCOF was found to increase with heel height. The increased uCOF observed in high heel shoes was related to an increase in the resultant shear force and decrease in the vertical force. Our results signify the need for proper public education and increased footwear industry awareness of how high heel shoes affect slip risk. PMID:21536444

    2016-07-01

    Viral warts or verruca pedis (plantar warts) are common skin conditions seen in both children and adults. Human papilloma virus (HPV), a DNA virus, is responsible for plantar verrucae. It needs an epidermal abrasion and a transiently impaired immune system to inoculate a keratinocyte. These entities are a therapeutic conundrum for many practitioners. This article discusses HPV infiltration and its subtypes involved in plantar warts; the evaluation of patients with plantar warts; and subsequent treatment options, such as laser, Candida albicans immunotherapy, topical therapy such as phytotherapy, and surgical excision.

    2012-12-01

    Trypanosome lytic factors (TLFs) are powerful, naturally occurring toxins in humans that provide sterile protection against infection by several African trypanosomes. These trypanocidal complexes predominantly enter the parasite by binding to the trypanosome haptoglobin/hemoglobin receptor (HpHbR), trafficking to the lysosome, causing membrane damage and, ultimately, cell lysis. Despite TLF-mediated immunity, the parasites that cause human African Trypanosomiasis (HAT), Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense, have developed independent mechanisms of resistance to TLF killing. In this review we describe the parasite defenses that allow trypanosome infections of humans and discuss how targeting these apparent strengths of the parasite may reveal their Achilles' heel, leading to new approaches in the treatment of HAT.

    1991-12-31

    Empty UF{sub 6} cylinders containing heel material were found to emit radiation levels in excess of 200 mr/hr, the maximum amount stated in ORO-651. The radiation levels were as high as 335 mr/hr for thick wall (48X and 48Y) cylinders and 1050 mr/hr for thin wall (48G and 48H) cylinders. The high readings were found only on the bottom of the cylinders. These radiation levels exceeded the maximum levels established in DOT 49 CFR, Part 173.441 for shipment of cylinders. Holding periods of four weeks for thick-wall cylinders and ten weeks for thin-wall cylinders were established to allow the radiation levels to decay prior to shipment.

    Malaria parasites have their Achilles' heel; they are vulnerable in small parts of their relevant molecules where they can be wounded and killed. These are sporozoite and merozoite protein conserved high activity binding peptides (cHABPs), playing a critical role in binding to and invasion of host cells (hepatocytes and erythrocytes, respectively). cHABPs can be modified by specific amino acid replacement, according to previously published physicochemical rules, to produce analogues (mHABPs) having left-handed polyproline II (PPIIL)-like structures which can modulate an immune response due to fitting perfectly into the HLA-DRβ1* peptide binding region (PBR) and having an appropriate presentation to the T-cell receptor (TCR).

    2016-06-27

    Osteoporosis is the most common metabolic disease with significant impact on the morbidity and mortality of affected patients. Osteoporosis has a significant impact on the economy worldwide. The aim of this study was to find out whether heel ultrasound is as good as central bone densitometry scanning in diagnosing osteoporosis in patients who are at high risk of osteoporosis. This was a prospective study of patients comparing heel ultrasound to central bone densitometry scanning (dual X-ray absorptiometry, DEXA) in patients. The recruited patients attended for a DEXA scan of the left hip and lumbar spine. All subjects had an ultrasound of the left heel using the quantitative heel ultrasound machine. The results of DEXA scan were blinded from the results of ultrasound and vice versa. There were 59 patients who took part in the study, 12 men and 47 women. The mean age was 66 years (SD 11.9) and mean weight was 62.5 kg (SD 10.7). The sensitivity and specificity of the ultrasound heel test to predict osteoporosis were 53% (95%CI: 29-77) and 86% (95%CI: 75-96) respectively. Specificity for predicting bone mineral density (BMD)-defined osteoporosis was high (86%), but sensitivity was low (53%). A heel ultrasound result in the osteoporotic range was highly predictive of BMD-defined osteoporosis. A positive ultrasound heel test in high risk patients is more useful in ruling in osteoporosis than a negative test to rule out osteoporosis. PMID:27433300

    Full Text Available Objective: Foot deformities, neuropathy, and dysfunction in the lower extremities are known risk factors that increase plantar peak pressure (PP and, as a result, the risk of developing foot ulcers in patients with diabetes. However, knowledge about the prevalence of these factors is still limited. The aim of the present study was to describe the prevalence of risk factors observed in patients with diabetes without foot ulcers and to explore possible connections between the risk factors and high plantar pressure. Patients and methods: Patients diagnosed with type 1 (n=27 or type 2 (n=47 diabetes (mean age 60.0±15.0 years were included in this cross-sectional study. Assessments included the registration of foot deformities; test of gross function at the hip, knee, and ankle joints; a stratification of the risk of developing foot ulcers according to the Swedish National Diabetes Register; a walking test; and self-reported questionnaires including the SF-36 health survey. In-shoe PP was measured in seven regions of interests on the sole of the foot using F-Scan®. An exploratory analysis of the association of risk factors with PP was performed. Results: Neuropathy was present in 28 (38%, and 39 (53% had callosities in the heel region. Low forefoot arch was present in 57 (77%. Gait-related parameters, such as the ability to walk on the forefoot or heel, were normal in all patients. Eighty percent had normal function at the hip and ankle joints. Gait velocity was 1.2±0.2 m/s. All patients were stratified to risk group 3. Hallux valgus and hallux rigidus were associated with an increase in the PP in the medial forefoot. A higher body mass index (BMI was found to increase the PP at metatarsal heads 4 and 5. Pes planus was associated with a decrease in PP at metatarsal head 1. Neuropathy did not have a high association with PP. Conclusions: This study identified several potential risk factors for the onset of diabetic foot ulcers (DFU. Hallux valgus

    2014-12-01

    Full Text Available Purpose. There has yet to be a combined analysis of three-dimensional multi-segment foot kinematics and plantar fascia strain in running gait at various degrees of inclination. The aim of the current study was therefore to investigate the above during treadmill running at different inclines (0°, 5°, 10° and 15°. Methods. Twelve male participants ran at 4.0 m · s-1 in the four different inclinations. Three-dimensional kinematics of the foot segments and plantar fascia strain were quantified for each incline and contrasted using one-way repeated measures ANOVA. Results and conclusions. The results showed that plantar fascia strain increased significantly as a function of running incline. Given the projected association between plantar fascia strain and the aetiology of injury, inclined running may be associated with a greater incidence of injury to the plantar fascia.

  2. How Plantar Exteroceptive Efficiency Modulates Postural and Oculomotor Control: Inter-Individual Variability.

    Science.gov (United States)

    Foisy, Arnaud; Kapoula, Zoï

    2016-01-01

    In a previous experiment, we showed that among young and healthy subjects, thin plantar inserts improve postural control and modify vergence amplitudes. In this experiment, however, significant inter-individual variability was observed. We hypothesize that its origin could be attributed to a different reliance upon feet cutaneous afferents. In order to test this hypothesis, we re-analyzed the data relative to 31 young (age 25.7 ± 3.8) and healthy subjects who participated in the first experiment after having classified them into two groups depending on their Plantar Quotient (PQ = Surface area of CoPfoam/Surface area of CoPfirm ground × 100). Foam decreases the information arising from the feet, normally resulting in a PQ > 100. Hence, the PQ provides information on the weight of plantar cutaneous afferents used in postural control. Twelve people were Plantar-Independent Subjects, as indicated by a PQ like the Normal Plantar Quotient Subjects: they were almost insensitive to the plantar stimulations in terms of postural control and totally insensitive in terms of oculomotor control. We conclude that the inter-individual variability observed in our first experiment is explained by the subjects' degree of plantar reliance. We propose that plantar independence is a dysfunctional situation revealing inefficiency in plantar cutaneous afferents. The latter could be due to a latent somatosensory dysfunction generating a noise which prevents the CNS from correctly processing and using feet somatosensory afferents both for balance and vergence control: Plantar Irritating Stimulus. Considering the non-noxious nature and prevalence of this phenomenon, these results can be of great interest to researchers and clinicians who attempt to trigger postural or oculomotor responses through mechanical stimulation of the foot sole.

    Shock absorption is the most important function of the human heel pad. However, changes in heel pad elasticity, as seen in e.g. long-distance runners, diabetes patients, and victims of Falanga torture are affecting this function, often in a painful manner. Assessment of heel pad elasticity is....... Elastic moduli were found from the resulting stress–strain curves. The elastic moduli made it possible to distinguish eight of nine phantoms from each other according to the manufactured stiffness and showed very little dependence of the thickness. Mean elastic moduli for the three soft, the three medium......, and the three hard phantoms were 89kPa, 153kPa, and 168kPa, respectively. The combination of ultrasound images and force measurements provided an effective way of assessing the elastic properties of the heel pad due to the internal strain estimation....

    Along with Vietnam's development, various hydraulic constructions including concrete gravity dams have been being built. In some of these dams, the fractures occurred at the heel of the dams are even in small and media dams. There are various reasons cause the factures at dam heel but the main reason is the stress states at dam heel are not determined correctly while designing dam. In this paper, several factors affecting stress solution at concrete gravity dam heel such as element mesh size, crack joints of upstream foundation, execution process are investigated by using finite element model of Banve concrete gravity dam. This work is very significant when the more high concrete gravity dams will be constructed in Vietnam year after year.

    The aim of this study was to determine the normal values of the heel-pad thickness and compressibility, and to compare these parameters according to age, gender and body mass index (BMI). 94 volunteers without any heel problems were selected. The heel-pad thickness was measured by ultrasound. The compressibility, which manifested as the compressibility index (CI), was calculated as the ratio of the loaded heel-pad thickness (LHPT) to the unloaded heel-pad thickness (UHPT). The average UHPT and CI were 1.26 cm and 0.50 in group A (20-34 years), 1.25 cm and 0.54 in group B (35-49 years), and 1.09 cm and 0.57 in group C (50-65 years). The average UHPT and CI were 1.22 cm and 0.53 in males and 1.11 cm and 0.53 in females. The average values for the UHPT and CI were 1.15 cm and 0.53 in the normal weight group, and 1.27 cm and 0.57 in the overweight group. The value of the UHPT was greater in men than in women, and showed a tendency to decrease with increase age. The CI increased with age, but there was no significant gender difference. The increased BMI in men led to an increase in the UHPT and CI. The average values of the heel-pad thickness and CI in the population without heel problems will be beneficial in providing background information and diagnostic information on patients with heel pain

Flow patterns calculated by the model were used to evaluate the performance of various combinations of operating pumps and their orientation. The models focused on removal of the sludge heel located at the edge of Tank 11 using the four existing slurry pumps. The models and calculations were based on prototypic tank geometry and expected normal operating conditions as defined by Tank Closure Project (TCP) Engineering. Computational fluid dynamics models of Tank 11 with different operating conditions were developed using the FLUENT(tm) code. The modeling results were used to assess the efficiency of sludge suspension and removal operations in the 75-ft tank. The models employed a three-dimensional approach, a two-equation turbulence model, and an approximate representation of flow obstructions. The calculated local velocity was used as a measure of sludge removal and mixing capability. For the simulations, a series of the modeling calculations was performed with indexed pump orientations until an efficient flow pattern near the potential location of the sludge mound was established for sludge removal. The calculated results demonstrated that the existing slurry pumps running at 1600 rpm could remove the sludge mound from the tank with a 103 in. liquid level, based on a minimum sludge suspension velocity of 2.27 ft/sec. In this case, the only exception is the region within about 2 ft. from the tank wall. Further results showed that the capabilities of sludge removal were affected by the indexed pump orientation, the number of operating pumps, and the pump speed. A recommended operational strategy for an efficient flow pattern was developed to remove the sludge mound assuming that local fluid velocity can be used as a measure of sludge suspension and removal. Sensitivity results showed that for a given pump speed, a higher tank

    Full Text Available Theories of motor skill acquisition postulate that attentional demands of motor execution decrease with practice. Hence, motor experts should experience less attentional resource conflict when performing a motor task in their domain of expertise concurrently with a demanding cognitive task. We assessed cognitive and motor performance in high-heel experts and novices who were performing a working memory task while walking in gym shoes or high heels on a treadmill. Surprisingly, neither group showed lower working memory performance when walking than when sitting, irrespective of shoe type. However, high-heel experts adapted walking regularity more flexibly to shoe type and cognitive load than novices, by reducing the variability of time spent in the single-support phase of the gait cycle in high heels when cognitively challenged. We conclude that high-heel expertise is associated with more flexible adjustments of movement patterns. Future research should investigate whether a more demanding walking task (e.g., wearing high heels on uneven surfaces and during gait perturbations results in expertise-related differences in the simultaneous execution of a cognitive task.

    Objective. To determine the postoperative appearance of the plantar fascia on MR imaging after a fasciotomy has been performed, and to compare the postsurgical appearance of the fascia after an open and endoscopic procedure.< rate at head-abs-p1.lf>Design and patients. Fifteen asymptomatic volunteers (12 women, 3 men; age range 22-49 years, mean age 33 years) with prior fasciotomies for treatment of longstanding plantar fasciitis were studied. Fourteen volunteers had a unilateral release and one volunteer had bilateral releases, allowing for assessment of 16 ankles. Eight fasciotomies were performed through an open incision and eight were performed endoscopically. The average time between surgery and imaging was 24 months (range 11-46 months). The site of surgery was established from the operative reports. Proton density (PD)-weighted and T2-weighted images in three orthogonal planes were obtained on a 1.5-T magnet. In eight studies, T1-weighted sagittal and STIR sagittal images were included. The fascia in each ankle was assessed for morphology and signal intensity. Perifascial soft tissues and bone marrow were assessed for edema. Preoperative MR studies were available in five volunteers.< rate at head-abs-p1.lf>Results. There was no apparent difference in the postoperative appearance of the ankle after an open or endoscopic procedure except for scar formation in the subcutaneous fat which was common after an open procedure (P<0.05). Three ankles had a gap in the fascia (one open, two endoscopic). The plantar fascia measured a mean of 7.0 mm (range 5-10 mm) at the fasciotomy, and 8.3 mm (range 6-12 mm) at the enthesis. At the fasciotomy, 11 of 13 ankles had an indistinct deep contour and 9 of 13 had an indistinct superficial contour. At the enthesis, 13 of 16 ankles had an indistinct deep contour and 6 of 16 had an indistinct superficial contour. Compared with preoperative MR studies there was an average reduction in the fascial thickness at the enthesis of 14

  11. Heel effect adaptive flat field correction of digital x-ray detectors

    International Nuclear Information System (INIS)

    Purpose: Anode heel effect renders large-scale background nonuniformities in digital radiographs. Conventional offset/gain calibration is performed at mono source-to-image distance (SID), and disregards the SID-dependent characteristic of heel effect. It results in a residual nonuniform background in the corrected radiographs when the SID settings for calibration and correction differ. In this work, the authors develop a robust and efficient computational method for digital x-ray detector gain correction adapted to SID-variant heel effect, without resorting to physical filters, phantoms, complicated heel effect models, or multiple-SID calibration and interpolation.Methods: The authors present the Duo-SID projection correction method. In our approach, conventional offset/gain calibrations are performed only twice, at the minimum and maximum SIDs of the system in typical clinical use. A fast iterative separation algorithm is devised to extract the detector gain and basis heel patterns from the min/max SID calibrations. The resultant detector gain is independent of SID, while the basis heel patterns are parameterized by the min- and max-SID. The heel pattern at any SID is obtained from the min-SID basis heel pattern via projection imaging principles. The system gain desired at a specific acquisition SID is then constructed using the projected heel pattern and detector gain map.Results: The method was evaluated for flat field and anatomical phantom image corrections. It demonstrated promising improvements over interpolation and conventional gain calibration/correction methods, lowering their correction errors by approximately 70% and 80%, respectively. The separation algorithm was able to extract the detector gain and heel patterns with less than 2% error, and the Duo-SID corrected images showed perceptually appealing uniform background across the detector.Conclusions: The Duo-SID correction method has substantially improved on conventional offset/gain corrections for

    Charcot foot is a serious complication of diabetes, characterized by deformity and overlying ulceration. The condition most commonly affects the midfoot. However, little information is available on the use of a medial plantar artery flap to treat diabetic midfoot ulceration. The purpose of the present study was to evaluate the versatility of ostectomy and medial plantar flap reconstruction for midfoot plantar ulceration associated with rocker-bottom deformity secondary to Charcot foot. Four patients underwent ostectomy and medial plantar flap reconstruction. Before flap reconstruction, the devitalized soft tissues and bone were radically resected. After the infection had been controlled, the ulcerated portion was minimally excised, and the bony prominence underlying the ulcer was removed. A medial plantar artery flap was applied to the ulcer. The donor site was covered with a split-thickness skin graft or artificial dermis. In all patients, the ulcers healed and independent ambulation was achieved. However, 1 patient experienced ulcer recurrence, and subsequent infection necessitated a major amputation. Limb salvage is challenging in the setting of deformity and intractable plantar ulceration. The advantages of medial plantar artery flap reconstruction are that tissues with a rich blood supply are used to cover the exposed bone, and the flap can withstand the pressure and shear stress of the patient's body weight. However, a dominant artery in the foot is sacrificed. Therefore, the patency of the dorsalis pedis artery must be confirmed in every patient. The results of the present study have demonstrated that a medial plantar artery can be an effective alternative for diabetic patients with a plantar ulcer secondary to Charcot foot. PMID:26190780

    The goal of this project was to examine the effects of artificial gravity (2.5 g) on skeletal muscle strength and key anabolic/catabolic markers known to regulate muscle mass. Two groups of subjects were selected for study: 1) a 21 day-bed rest (BR) control (C) group (N=7); and 2) an AG group (N=8), which was exposed to 21 days of bed-rest plus daily 1 hr exposures to AG (2.5 g). This particular experiment was part of an integrated AG Pilot Project sponsored by NASA/Johnson Space Center. The in vivo torque-velocity relationships of the knee extensors and plantar flexors of the ankle were determined pre and post treatment. Also, pre- and post treatment biopsy samples were obtained from both the vastus lateralis and soleus muscles and were used, in part, for a series of analyses on gene expression (mRNA abundance) of key factors implicated in the anabolic versus catabolic state of the muscle. Post/Pre toque-velocity determinations revealed greater decrements in knee extensor performance in the C versus AG group (P less than 0.04). The plantar flexor muscle group of the AG subjects actually demonstrated a net gain in torque-velocity relationship; whereas, in the C group the overall post/pre responses declined (AG vs C; P less than 0.001). Measurements of muscle fiber cross-sectional area (for both muscles) demonstrated a loss of approx. 20% in the C group while no losses were evident in the AG group. RT-PCR analyses of muscle biopsy specimens demonstrated that markers of growth and cytoskeletal integrity (IGF-1, IGF-1 BP4, mechano growth factor, total RNA, and pro-collagen 3a) were higher in the AG group, whereas catabolic markers (myostatin and atrogen) were elevated in the C group. Importantly, these patterns were seen in both muscles. Based on these observations we conclude that paradigms of AG have the potential to maintain the functional, biochemical, and structural homeostasis of skeletal muscle in the face of chronic unloading states.

    Objective To investigate feasible treatment methods for plantar ulcers in leprosy patients according to the agreement between the Ministry of Health (MOH) of China and the Leprosy Mission International (LMI).Methods A total of 2599 complicated foot ulcers in 1804 leprosy cases underwent surgic treatment. Plastic fixation and supports were used, dressings were changed regularly, and protective footwear and modified insoles were provided.Results Of the 2599 foot ulcers 1446 (55.64%) healed. The cure rate of the patients treated in leprosy hospitals was 71.31%, with 219 (15.15%) recurrences of foot ulcers. The recurrence rate of those who lived at home was 18.35%.Conclusions Comprehensive treatment of foot ulcers has a high cure rate and a low recurrence rate. Reduction of workload, avoidance of long distance walking, intensification of education on foot self-care and provision of financial support are the main measures for preventing a recurrence of foot ulcers.

    2016-06-01

    Background Plantar, neuropathic, or trophic ulcers are often found in patients with decreased sensation in the foot. These ulcers can be complicated by infection, deformity, and increased patient morbidity. Excision results in wider defects and local tissues are often insufficient for reconstruction Methods Total 26 free flaps were used in 25 patients to reconstruct plantar ulcers between years 2007 and 2013. The etiology included diabetic neuropathy (n = 13), leprosy (n = 3), spinal/peripheral nerve injury (n = 7), spina bifida (n = 1), and peripheral neuropathy (n = 1). The duration of the ulcer ranged from 1 to 18 years. Fifteen patients had associated systemic comorbidities and six had previous attempts. Free flaps used in reconstruction were the anterolateral thigh flap (n = 18), radial artery forearm flap (n = 4), and the gracilis muscle flap (n = 4). Recipient vessels were the posterior tibial artery (end to side) in 19 and the dorsalis pedis artery in 7. Results The average age at presentation was 44.6 years with mean duration of ulcer of 5.8 years predominantly located over weight-bearing areas. Mean size of ulcer was 59.45 cm(2) and mean follow-up period was 48 months. All flaps survived except a partial loss. Average time to resume ambulation was 6 weeks. Three patients had recurrence with mean follow-up of 48 months. Secondary flap reduction and bony resection was done in four. Conclusion Microvascular reconstruction of the sole has advantages of vascularity, adequate tissue, and leaving rest of the foot undisturbed for offloading. Three significant local conditions influencing selection and transfer of the flap include (1) distally located forefoot ulcers, (2) extensive subcutaneous fibrosis secondary to frequent inflammation, and (3) Charcot arthropathy. In our series, the anterolateral thigh flap is our first choice for reconstruction of these defects. PMID:26910652

    Purpose: The study was aimed to investigate plantar fascia thickness at different locations in healthy asymptomatic subjects and its relationship to the following variables: weight, height, sex and age. Material and methods: The study evaluates 96 feet of healthy asymptomatic volunteers. The plantar fascia thickness was measured at four different locations: 1 cm proximal to the insertion of the plantar fascia, at the insertion of the plantar fascia on the calcaneus and separate out 1 cm + 2 cm distal to the insertion. A 10 MHz linear-array transducer was used. Results: There were statistically significant differences in plantar fascia thickness at the four different locations (p < 0.001) although no differences in PF thickness were found between the two distal from insertion locations (1 and 2 cm). Multiple regression analysis showed sex as independent predictor of plantar fascia thickness at 1 cm proximal to the insertion. At origin and 1 cm distal to insertion weight was an independent predictor of plantar fascia thickness. Conclusions: There are differences of thickness at different locations of plantar fascia measured by ultrasonography. Thickness at 1 cm proximal to the insertion is influenced by sex and thickness at origin and at 1 cm distal to the insertion has a direct relationship with body weight. This could be attributed to the overloading effect that weight has on plantar fascia in healthy symptomatic subjects at these two locations. Height and age did not seem to influence as independent variables in plantar fascia thickness among non-painful subjects.

    We carried out an experiment to measure the relationship between tensile force in the tendoachilles and plantar fascia strain, and how this relationship is affected by the metatarsophalangeal joint dorsiflexion angle. Eight cadaver lower extremity specimens underwent biomechanical testing. Using a servo-hydraulic testing machine, a tensile force up to 500 N was applied to the tendoachilles while the strain on the plantar fascia was measured using an extensometer. The experiment was repeated at four different metatarsophalangeal joint dorsiflexion angles (0 degrees, 5 degrees, 30 degrees, and 45 degrees). Measurements and calculations showed that dorsiflexion of the toes tightens the plantar fascia (the windlass effect) and increases the effect that a tensile force in the tendoachilles has on the tensile strain and tensile force in the plantar fascia.

    Full Text Available BACKGROUND: Flat foot is a typical clinical sign in childhood, expressed as valgus positioning of the heel during vertical foot loading. This may lead to medial deviation of the foot axis and cause overloading of some foot areas. OBJECTIVE: To determine the influence of valgus position of the heel (both bilateral and unilateral on foot loading during gait. METHODS: An experimental group consisting of children with bilateral heel valgus deformity (16 children, age 5.3 ± 1.3 years and children with unilateral heel valgus deformity (14 children, age 5.6 ± 1.6 years. The control group comprised of 14 children (age 4.5 ± 1.2 years. For measuring foot loading during gait, the Footscan (RSScan International, Olen, Belgium pressure plate was used. Each subject went through 8 trials of gait measurement. From each trial, 8 foot areas were evaluated. Data processing with mean values for each subject was performed by non-parametric tests (Mann-Whitney and Wilcoxon tests, Spearman correlation in the STATISTICA programme (StatSoft, Inc., Tulsa, USA. RESULTS: Pressure peak and pressure impulse in the first metatarsal was greater for the bilateral valgus group (p CONCLUSION: The results show that valgus positioning of the heel influences foot loading in children during gait. The findings of this study suggest the necessity of a complex solution to the problem of preventing further progression of pathological changes.

    Gross motion of the ankle joint complex (AJC) is a summation of the ankle and subtalar joints. Although AJC kinematics have been widely used to evaluate the function of the AJC, the coordinated movements of the ankle and subtalar joints are not well understood. The purpose of this study was to accurately quantify the individual kinematics of the ankle and subtalar joints in the intact foot during ground walking by using a bi-planar fluoroscopic system. Bi-planar fluoroscopic images of the foot and ankle during walking and standing were acquired from 10 healthy subjects. The three-dimensional movements of the tibia, talus, and calcaneus were calculated with a three-dimensional/two-dimensional registration method. The skeletal kinematics were quantified from 9% to 86% of the full stance phase because of the limited camera speed of the X-ray system. At the beginning of terminal stance, plantar-flexion of the AJC was initiated in the subtalar joint on average at 75% ranging from 62% to 76% of the stance phase, and plantar-flexion of the ankle joint did not start until 86% of the stance phase. The earlier change to plantar-flexion in the AJC than the ankle joint due to the early plantar-flexion in the subtalar joint was observed in 8 of the 10 subjects. This phenomenon could be explained by the absence of direct muscle insertion on the talus. Preceding subtalar plantar-flexion could contribute to efficient and stable ankle plantar-flexion by locking the midtarsal joint, but this explanation needs further investigation. PMID:26238571

    Objective:The present study was to explore the adverse effect of obesity on plantar morphology in 4-6 years old preschool children by analyzing the characteristics of plantar pressure distribution between obese and normal children, and to make some intervene suggestions. Methods: According to the obesity-related definitions by WHO, 47 obese children from 4 district kindergartens in Zhejiang Province were chose to be studied as obese preschool subject. Meanwhile, 47 ordinary children were chose as normal subject corresponding to the gender and age. The research instruments were Inbody J20 (Korea) and Rscan (Belgium). The differences of contact time(CT), contact area(CA), peak pressure(PP) between these two groups were investigated to explore the impact of obesity on plantar pressure. Results: The contact time of obese children during walking was longer than that of normal group. The contact area and peak pressure of heel and metatarsal of the obesities were higher that those of the normal. Especially the difference of CT and PP in the arch region between these two groups was more remarkable. Conclusions: The obese children performing the body buffering and the taking off were not as good as the normal children. And they displayed poor stability. The characteristics of plantar pressure in obese children were closer to those of flatfoot gait and should be paid more attentions.%目的:分析了学龄前肥胖与正常儿童(4~6岁)自然行走时足底压力的分布特征,旨在探讨肥胖对儿童足部形态的不利影响,进而提出干预措施.方法:采用韩国Inbody J20和比利时Rsscan足底压力板测试系统对浙江省4所不同地市幼儿园的691名4~6岁学龄前儿童进行测量.根据WHO的相关定义,筛选出47人为肥胖儿童组,按性别和年龄配对随机抽取体重正常儿童47人为正常组,分别研究在接触时间、接触面积、压力峰值等指标方面的差异,来探索肥胖对足底压力的影响.结果:肥胖

    2010-01-01

    During human walking, plantar flexor activation in late stance helps to generate a stable and economical gait pattern. Because plantar flexor activation is highly mediated by proprioceptive feedback, the nervous system must modulate reflex pathways to meet the mechanical requirements of gait. The purpose of this study was to quantify ankle joint mechanical output of the plantar flexor stretch reflex response during a novel unexpected gait perturbation. We used a robotic ankle exoskeleton to m...

  19. Occurrence, Characterization and Synthesis of Hanford and SRS Tank Heel Materials

    International Nuclear Information System (INIS)

    The long-range objective of this study was to develop chemically assisted technologies for removing heels from tanks. In FY 01, the first two steps toward this objective were taken: (1) catalogue the occurrence and nature of tank heels and assess which materials are available for study and (2) develop methods for synthesizing non-radioactive surrogate heel materials for use in testing potential removal technologies. The chief finding of Task 1 was the existence of ''heels'', depending on the definition used. Hard materials that would be almost impossible to remove by sluicing are all but absent from the records of both Savannah River and Hanford. Historical usage suggests that the term ''heel'' may also apply to chunky, granular, or semi-solid pasty accumulations. These materials are documented and may also be difficult to remove by conventional sluicing technologies. Such heels may be comprised of normal sludge components, dominantly iron and aluminum hydroxides, or they may result from added materials which were not part of the normal fuel reprocessing operations: Portland cement, diatomaceous earth, sand and soil and spent zeolite ion exchange ''resins''. The occurrence and chemistry of the most notable ''heel'', that of the zeolite mass in Tank 19F at Savannah River, is reviewed in some detail. Secondly, no clear correlation was found between high tank temperatures and difficulties encountered in removing materials from a tank at a later date; nor did the sludges from these tanks give any indication of being particularly solid. Experimental studies to develop synthetic heel materials were caned out using a number of different approaches. For normal sludge materials settling, even when assisted by a centrifuge, it proved ineffective. The same result was obtained from drying sludge samples. Even exposing sludges to a molten salt melt at 233 C, only produced a fine powder, rather than a resilient ceramic which resisted disaggregation. A cohesive material, however

    Elastic energy returned from passive-elastic structures of the lower limb is fundamental in lowering the mechanical demand on muscles during running. The purpose of this study was to investigate the two length-modulating mechanisms of the plantar fascia, namely medial longitudinal arch compression and metatarsophalangeal joint (MPJ) excursion, and to determine how these mechanisms modulate strain, and thus elastic energy storage/return of the plantar fascia during running. Eighteen runners (9 forefoot and 9 rearfoot strike) performed three treadmill running trials; unrestricted shod, shod with restricted arch compression (via an orthotic-style insert), and barefoot. Three-dimensional motion capture and ground reaction force data were used to calculate lower limb kinematics and kinetics including MPJ angles, moments, powers and work. Estimates of plantar fascia strain due to arch compression and MPJ excursion were derived using a geometric model of the arch and a subject-specific musculoskeletal model of the plantar fascia, respectively. The plantar fascia exhibited a typical elastic stretch-shortening cycle with the majority of strain generated via arch compression. This strategy was similar in fore- and rear-foot strike runners. Restricting arch compression, and hence the elastic-spring function of the arch, was not compensated for by an increase in MPJ-derived strain. In the second half of stance the plantar fascia was found to transfer energy between the MPJ (energy absorption) and the arch (energy production during recoil). This previously unreported energy transfer mechanism reduces the strain required by the plantar fascia in generating useful positive mechanical work at the arch during running. PMID:27054319

    Acquired flatfoot deformity in adults is usually due to partial or complete tearing of the posterior tibial tendon, with secondary failure of other structures such as the plantar calcaneonavicular (spring) ligament (SL), which maintain the medial longitudinal arch. In flexible cases, the tibialis posterior can be replaced with the flexor digitorum longus. It is common practice to suture the SL directly in the case of a tear; however, if the tear is complete, suturing directly to the ligament alone will not be possible. Reconstruction of the ligament is needed; however, no validated methods are available to reconstruct this ligament. The operative technique of SL reconstruction described in this report as a part of acquired flatfoot deformity reconstruction consists of augmenting remnants of the spring from the navicularis to the sustentaculum tali and suspending it to the medial malleolus using 2-mm-wide, long-chain polyethylene suture tape. This technique results in the firm anatomic reconstruction of the SL, in addition to "classic" medial arch reconstruction. We recommend SL reconstruction for medial arch reconstruction when the SL is torn. PMID:26253476

    The aim of this study is to investigate the differences in lower limb kinematics and kinetics between experienced (EW) and inexperienced (IEW) moderate high-heel wearers during jogging and running. Eleven experienced female wearers of moderate high-heel shoes and eleven matched controls participated in jogging and running tests. A Vicon motion analysis system was used to capture kinematic data and a Kistler force platform was used to collect ground reaction force (GRF). There were no significant differences in jogging and running speed respectively. Compared with IEW, EW adopted larger stride length (SL) with lower stride frequency (SF) at each corresponding speed. During running, EW enlarged SL significantly while IEW increased both SL and SF significantly. Kinematic data showed that IEW had generally larger joint range of motion (ROM) and peak angles during stance phase. Speed effect was not obvious within IEW. EW exhibited a significantly increased maximal vertical GRF (Fz2) and vertical average loading rate (VALR) during running, which was potentially caused by overlong stride. These suggest that both EW and IEW are at high risk of joint injuries when running on moderate high heels. For wearers who have to do some running on moderate high heels, it is crucial to control joint stability and balance SL and SF consciously. PMID:27101561

    Shock absorption and stability during landings is provided by both, gymnast ability and mat properties. The aims of this study were to determine the influence of different mat constructions on their energy absorption and stability capabilities, and to analyse how these properties affect gymnast's plantar pressures as well as subjective mat perception during landing. Six mats were tested using a standard mechanical drop test. In addition, plantar pressures and subjective perception during landing were obtained from 15 expert gymnasts. The different mats influenced plantar pressures and gymnasts' subjective perception during landing of gymnasts. Significant correlations between plantar pressures at the medial metatarsal and lateral metatarsal zones of the gymnasts' feet with the different shock absorption characteristics of the mats were found. However, subjective perception tests were not able to discriminate mat functionality between the six mats as no significant correlations between the mechanical mat properties with the subjective perception of these properties were found. This study demonstrated that plantar pressures are a useful tool for discriminating different landing mats. Using similar approaches, ideally including kinematics as well, could help us in our understanding about the influences of different mats upon gymnast-mat interaction. PMID:21309299

  11. Dissolution of Plutonium Scrub Alloy and Anode Heel Materials in H-Canyon

    International Nuclear Information System (INIS)

    H-Canyon has a ''gap'' in dissolver operations during the last three months of FY03. One group of material to be processed during the gap is pre-existing scrub alloy material. There are 14 cans of material containing approximately 3.8 kilograms of plutonium. Of the 14 cans, it was anticipated that four cans contain salts, two cans contain anode heel materials, and eight cans contain scrub alloy buttons. H-Canyon desires to process the materials using a flowsheet similar to the SS and C (sand, slag and crucible) dissolution flowsheet used in F-Canyon. The materials will be loaded into carbon steel cans and then placed into aluminum metal charging bundles. Samples were sent to Savannah River Technology Center (SRTC) for characterization and flowsheet testing -- four MSE salts, two anode heels, and seven scrub alloy buttons. SRTC dissolved and characterized each of the samples. Two of them, originally thought to be MSE salts, were found to be graphite mold materials and were unsuitable for processing in H-Canyon. Characterization studies confirmed that the identification of the remaining items as MSE salts, scrub alloy buttons, and anode heel materials was correct. The MSE salts and anode heels solids are comprised primarily of plutonium, potassium, sodium and chloride. Both the MSE salts and anode heels left behind small amounts of residual solids. The scrub alloy buttons are comprised primarily of plutonium and aluminum. The solids dissolve readily with light, effervescent gas generation at the material surface and only trace amounts of NOx generation. Of the seven button samples, four dissolved completely. Two button samples contained small amounts of tantalum that did not dissolve. The last of the seven scrub alloy samples left a trace amount of residual plutonium solids. It is anticipated that the presence of undissolved fissile material is a function of where the sample was located relative to the button surface

    2008-02-01

    Full Text Available Abstract Background Excessive pronation (or eversion at ankle joint in heel-toe running correlated with lower extremity overuse injuries. Orthotics and inserts are often prescribed to limit the pronation range to tackle the problem. Previous studies revealed that the effect is product-specific. This study investigated the effect of medial arch-heel support in inserts on reducing ankle eversion in standing, walking and running. Methods Thirteen pronators and 13 normal subjects participated in standing, walking and running trials in each of the following conditions: (1 barefoot, and shod condition with insert with (2 no, (3 low, (4 medium, and (5 high medial arch-heel support. Motions were captured and processed by an eight-camera motion capture system. Maximum ankle eversion was calculated by incorporating the raw coordinates of 15 anatomical positions to a self-compiled Matlab program with kinematics equations. Analysis of variance with repeated measures with post-hoc Tukey pairwise comparisons was performed on the data among the five walking conditions and the five running conditions separately. Results Results showed that the inserts with medial arch-heel support were effective in dynamics trials but not static trials. In walking, they successfully reduced the maximum eversion by 2.1 degrees in normal subjects and by 2.5–3.0 degrees in pronators. In running, the insert with low medial arch support significantly reduced maximum eversion angle by 3.6 and 3.1 degrees in normal subjects and pronators respectively. Conclusion Medial arch-heel support in inserts is effective in reducing ankle eversion in walking and running, but not in standing. In walking, there is a trend to bring the over-pronated feet of the pronators back to the normal eversion range. In running, it shows an effect to restore normal eversion range in 84% of the pronators.

    Full Text Available Abstract Background It has been proposed that high-heeled shoes may contribute to the development and progression of knee pain. However, surprisingly little research has been carried out on how shoe heel height affects muscle activity around the knee joint. The purpose of this study was to investigate the effect of differing heel height on the electromyographic (EMG activity in vastus medialis (VM and vastus lateralis (VL during a sit to stand activity. This was an exploratory study to inform future research. Methods A repeated measures design was used. Twenty five healthy females carried out a standardised sit to stand activity under 4 conditions; barefoot, and with heel wedges of 1, 3, and 5 cm in height. EMG activity was recorded from VM and VL during the activity. Data were analysed using 1 × 4 repeated measures ANOVA. Results Average rectified EMG activity differed with heel height in both VM (F2.2, 51.7 = 5.24, p 3, 72 = 5.32, p 3, 72 = 0.61, p = 0.609. Conclusion We found that as heel height increased, there was an increase in EMG activity in both VM and VL, but no change in the relative EMG intensity of VM and VL as measured by the VM: VL ratio. This showed that no VM: VL imbalance was elicited. This study provides information that will inform future research on how heel height affects muscle activity around the knee joint.

    The effect of activated carbon's pore size distribution (PSD) on heel formation during adsorption of organic vapors was investigated. Five commercially available beaded activated carbons (BAC) with varying PSDs (30-88% microporous) were investigated. Virgin samples had similar elemental compositions but different PSDs, which allowed for isolating the contribution of carbon's microporosity to heel formation. Heel formation was linearly correlated (R(2)=0.91) with BAC micropore volume; heel for the BAC with the lowest micropore volume was 20% lower than the BAC with the highest micropore volume. Meanwhile, first cycle adsorption capacities and breakthrough times correlated linearly (R(2)=0.87 and 0.93, respectively) with BAC total pore volume. Micropore volume reduction for all BACs confirmed that heel accumulation takes place in the highest energy pores. Overall, these results show that a greater portion of adsorbed species are converted into heel on highly microporous adsorbents due to higher share of high energy adsorption sites in their structure. This differs from mesoporous adsorbents (low microporosity) in which large pores contribute to adsorption but not to heel formation, resulting in longer adsorbent lifetime. Thus, activated carbon with high adsorption capacity and high mesopore fraction is particularly desirable for organic vapor application involving extended adsorption/regeneration cycling.

    Plexiform neurofibromas are benign tumors of the peripheral nerve. Diagnosis may be challenging, if they present mimicking other peripheral nerve pathologies. We report the case of a patient who had severe foot pain, which progressively hampered her walking ability, erroneously attributed to recurrent Morton's neuroma. Diagnosis of plexiform neurofibroma of her right medial plantar nerve was made 15 years after the appearance of symptoms. Pain and function recovered after radical neurotomy of the medial plantar nerve. A correct diagnosis is an essential starting point in the treatment of neurofibromas and a misdiagnosis may lead to an inappropriate treatment. PMID:25024003

    2010-02-16

    The Retrieval Knowledge Center sponsored a meeting in June 2009 to review challenges and gaps to retrieval of tank waste heels. The facilitated meeting was held at the Savannah River Research Campus with personnel broadly representing tank waste retrieval knowledge at Hanford, Savannah River, Idaho, and Oak Ridge. This document captures the results of this meeting. In summary, it was agreed that the challenges to retrieval of tank waste heels fell into two broad categories: (1) mechanical heel waste retrieval methodologies and equipment and (2) understanding and manipulating the heel waste (physical, radiological, and chemical characteristics) to support retrieval options and subsequent processing. Recent successes and lessons from deployments of the Sand and Salt Mantis vehicles as well as retrieval of C-Area tanks at Hanford were reviewed. Suggestions to address existing retrieval approaches that utilize a limited set of tools and techniques are included in this report. The meeting found that there had been very little effort to improve or integrate the multiple proven or new techniques and tools available into a menu of available methods for rapid insertion into baselines. It is recommended that focused developmental efforts continue in the two areas underway (low-level mixing evaluation and pumping slurries with large solid materials) and that projects to demonstrate new/improved tools be launched to outfit tank farm operators with the needed tools to complete tank heel retrievals effectively and efficiently. This document describes the results of a meeting held on June 3, 2009 at the Savannah River Site in South Carolina to identify technology gaps and potential technology solutions to retrieving high-level waste (HLW) heels from waste tanks within the complex of sites run by the U. S. Department of Energy (DOE). The meeting brought together personnel with extensive tank waste retrieval knowledge from DOE's four major waste sites - Hanford, Savannah River

    Objective The purpose of this study was to examine whether there were differences in the perceived comfort, plantar pressure, and rearfoot motion between laced running shoes and elastic-covered running shoes. Methods Fifteen male amateur runners participated in the study. The perceived comfort, plantar loading, and rearfoot motion control (inversion and eversion of the heel to the shank) of each type of shoes during running were recorded. Results When the laced running shoes and elasticcovered running shoes were compared, the elastic-covered running shoes showed lower perceived comfort rating in terms of shoe length, width, heel cup fitting, and forefoot cushioning. The elasticcovered running shoes also recorded higher peak plantar pressure in the lateral side of the forefoot,as well as larger maximum rearfoot pronation. Conclusions Overall, shoelaces can help runners obtain better foot-shoe fit. Moreover, shoelaces may help prevent injury in running by better controlling the aforementioned factors.%目的:比较穿着鞋带跑鞋和采用松紧鞋舌跑鞋在主观舒适度、足底压力分布和后足运动参数方面的区别.方法:15名有经验的跑步者自愿参与本研究.采用一份可靠的问卷进行主观舒适度调查;采用Novel pedar足底压力测试系统记录受试者穿着两种跑鞋跑步时的足底压力分布;采用二维高速摄像系统和Ariel动作解析系统记录、分析受试者穿着两种跑鞋跑步时后足的运动图像及足跟相对小腿的内、外翻参数.结果:与穿着有鞋带跑鞋比较,受试者在穿着松紧鞋舌跑鞋跑步时的主观舒适度较差,第4和第5跖趾关节分区足底压强明显增加,后足外翻角度较大.结论:松紧鞋舌式设计并不适用于跑鞋.有鞋带跑鞋合脚性更好,可以帮助跑步者固定鞋内的脚.

    [Purpose] The purpose of this study was to determine the effects of wearing high heels while driving on lower extremity muscle activation. [Subjects] The subjects of this experimental study were 14 healthy women in their 20s who normally wear shoes with high heels. [Methods] The subjects were asked to place their shoes on an accelerator pedal with the heel touching the floor and then asked to press the pedal with as much pressure as possible for 3 seconds before removing their feet from the pedal. A total of 3 measurements were taken for each heel height (flat, 5 cm, 7 cm), and the heel height was randomly selected. [Results] The levels of muscle activity, indicated as the percentage of reference voluntary contraction, for gastrocnemius muscle in the flat, 5 cm, and 7 cm shoes were 180.8±61.8%, 285.4±122.3%, and 366.2±193.7%, respectively, and there were significant differences between groups. Those for the soleus muscle were 477.3±209.2%, 718.8±380.5%, and 882.4±509.9%, and there were significant differences between groups. [Conclusion] To summarize the results of this study, it was found that female drivers require greater lower extremity muscle activation when wearing high heels than when wearing low heels. Furthermore, instability and muscle fatigue of the ankle joint, which results from wearing high heels on a daily basis, could also occur while driving. PMID:25435684

  6. Results of analgetic radiotherapy with 6MV photons for treatment of an inflammatory heel spur

    International Nuclear Information System (INIS)

    The anti-inflammatory radiotherapy is an established method for alleviating the pain in patients suffering from an inflammatory heel spur, and the value of the treatment under orthovoltage conditions has been proven and is shown in the literature. The work in hand presents initial results of a prospective study intended to examine the effectiveness of 6 MV photon radiation fields for treatment of heel spurs. The collective for the study reported covered 31 patients (27 females, 4 males). The radiation doses and applications and the evaluation of the results achieved at various intervals over treatment periods are reported and show that this analgetic radiotherapy achieves results about equal to those of orthovoltage irradiation techniques and thus can be recommended as an alternative treatment.

    1996-04-01

    In previous studies on the mechanical properties of the human heel pad (Bennett & Ker, 1990; Aerts et al. 1995) the fat pad and part of the calcaneus was removed from amputated test specimens. The present study tested whether this procedure influences the mechanical behaviour of the sample. Intact amputated feet were therefore mounted on steel rods driven through the calcaneus and placed in a mechanical test situation (pendulum or servohydraulic material tester). The mechanical properties of the pad were determined for a series of experiments in which the pad was gradually freed from the foot in the way done by Bennett & Ker (1990) and Aerts et al. (1995). The results showed no observable differences in the mechanics of the pad by isolating it from the rest of the foot. Thus, in relation to human locomotion, the load-deformation relation of heel pads as described by Aerts et al. (1995) is the most appropriate to date. PMID:8621341

    1990-08-01

    The acceleration in the sagittal plane of the prosthetic tube at heel strike in normal walking was measured in five healthy amputees with their definitive below-knee prosthesis, every subject using six different prosthetic feet, wearing sport shoes as well as leather shoes. The experiments were carried out in the rehabilitation centre "Het Roessingh", Enschede, The Netherlands. Maximum accelerations were extracted from the acceleration-time-signal. Mean acceleration maxima of all subjects were calculated for each foot-shoe combination to eliminate the individual influence of the subjects. In the axial direction the maximal accelerations demonstrate a clear difference among the prosthetic feet and the shoes, while in dorsoventral (tangential) direction the inter-individual variation in the acceleration extremes dominates the difference between the types of footwear. In comparison with non-amputees the magnitude of the maximal axial acceleration at heel strike does not differ significantly. PMID:2235301

  11. Radiation therapy for painful heel spurs. Results of a prospective randomized study

    International Nuclear Information System (INIS)

    Purpose: to evaluate the efficacy of two different dose-fractionation schedules for radiation therapy (RT) in patients with painful heel spurs. Patients and methods: 130 patients were randomized into two groups: the low-dose (LD) group (n = 65 heels) received a total dose of 3.0 Gy given in two weekly fractions of 0.5 Gy; in the high-dose (HD) group (n = 65 heels), two weekly fractions of 1.0 Gy were applied over 3 weeks (total dose 6.0 Gy). In 24 sites of the HD group and 17 sites of the LD group, a second RT course was given. The results were assessed using a five-level function score which was documented before RT, at the end of each RT course, and at 6 weeks and 6 months thereafter. Results: at 6-month follow-up, RT led to a highly significant reduction of symptoms in both groups. In the HD group, 31 sites were classified as excellent (score: 90-100), 13 as good (score: 70-85), twelve as moderate (score: 45-65), and nine as poor (score: 0-40). In the LD group, 35 sites were classified as excellent, eight as good, ten as moderate, and twelve as poor. The comparison of the difference of the sum score and the single criteria before RT and at 6 months after RT using the Wilcoxon-Mann-Whitney U-test revealed no statistically significant difference of response to RT between both groups. Conclusion: RT is an effective treatment option for the management of inflammatory heel spurs. The dose for an RT course should not exceed 3.0 Gy. (orig.)

    2015-11-01

    Offloading heel ulcers is a challenging task because strategies deemed to be most optimal from a medical perspective may be unacceptable to patients. Observed adverse dressing events and problems with offloading devices led to a pilot study and subsequent change in practice at the authors' Foot and Leg Ulcer Clinic. Starting in 2004, patients requiring offloading received a nonremovable padded heel dressing (PHD) that was changed twice a week by the visiting nurse. A retrospective quality improvement review was conducted to compare outcomes, nursing visits, and nursing visit costs for 40 consecutive patients with heel ulcers treated at this clinic with a nonremovable PHD (n = 20) or without a PHD (n = 20) between January 20, 2001 and December 31, 2006. Patient demographic data, relevant comorbidities, wound depth, weeks of care, adverse events, and treatment-related narrative comments were abstracted from patient records. Relevant comorbidities were similar in both groups. The PHD group was younger (average age of 74.6 [range 35-91] years) compared to PHD nonuse group (average age 79.5 [range 25-95] years; P less than 0.04). The PHD group required fewer total weeks of care compared to the nonuse group (368 versus 527 weeks, respectively; P less than 0.001), and average duration of clinic treatment in the PHD group was 18.40 (range 5-51) weeks versus 40.54 (range 6-88) weeks in the nonuse group. The PHD group had fewer total nursing visits (736 versus 1,581, P less than 0.001); the average number of nursing visits for the PHD was 36.80 (range 10-102) compared to 121.61 (range 18-264) for the nonuse group. Nursing visit costs were lower for PHD users ($114,080 versus $245,055, P less than 0.001), and the cost-efficiency ratio was less than one third (1:3.3) of PHD nonuse for the average heel ulcer. All 20 patients in the PHD use group had wound closure compared with the PHD nonuse group, in which 13 out of 20 wounds closed, 3 amputations were performed, and 4

    [Purpose] The purpose of this study was to determine the relationship between navicular drop and plantar flexion torque of the first and second-fifth metatarsophalangeal joints. [Subjects] Ten healthy young men participated in this study. [Methods] The Pearson product-moment correlation coefficient was calculated to determine the relationship between navicular drop and plantar flexion torque of the first and second-fifth metatarsophalangeal joints. [Results] Significant negative correlations were observed between navicular drop and plantar flexion torques in the lengthened position of the intrinsic toe plantar flexion muscles, but no correlations were found between navicular drop and plantar flexion torques in the neutral position of the ankle and metatarsophalangeal joints. Moreover, the intrinsic toe plantar flexion muscles were found to contribute to the formation of the medial longitudinal arch. [Conclusion] Navicular drop correlates with metatarsophalangeal joint muscle strength in plantar flexion where the intrinsic toe muscles are capable of exerting force. PMID:26180323

    The forces and moments acting at the hip joint influence the long-term stability of the fixation of endoprostheses and the course of coxarthrosis. These loads may depend on the kind of footwear and the walking or running style. These factors were investigated in a patient with instrumented hip implants. He wore different sports shoes, normal leather shoes, hiking boots and clogs and walked barefoot with soft, normal and hard heel strikes. The loads were lowest while walking and jogging without shoes. All shoes increased the joint force and the bending moment at the implant slightly but the torsional moment rose by up to 50%. No relation was found between the different type of shoes and the load increase, only shoes with very hard soles were clearly disadvantageous. Soft heels, soles or insoles did not offer advantages. Gait stability seems to play the most important role in increasing the joint loading and should be the criterion for the choice of footwear. Smooth gait patterns with soft heel strikes are the only means to reduce joint loading during slow jogging. PMID:7657680

  2. Tendons in the plantar aspect of the foot: MR imaging and anatomic correlation in cadavers

    International Nuclear Information System (INIS)

    The purpose of this anatomic imaging study was to illustrate the normal complex anatomy of tendons of the plantar aspect of the ankle and foot using magnetic resonance (MR) imaging with anatomic correlation in cadavers. Seven fresh cadaveric feet (obtained and used according to institutional guidelines, with informed consent from relatives of the deceased) were studied with intermediate-weighted fast-spin-echo MR imaging. For anatomic analysis, cadaveric specimens were sectioned in 3-mm-thick slices in the coronal and axial planes that approximated the sections acquired at MR imaging. The entire courses of the tendons into the plantar aspect of the foot were analyzed. The tibialis posterior tendon has a complex distal insertion. The insertions in the navicular, second, and third cuneiforms bones were identify in all cases using axial and coronal planes. A tendinous connection between the flexor hallucis longus and the flexor digitorum longus tendons was identified in five of our specimens (71%). The coronal plane provided the best evaluation. The peroneus longus tendon changes its direction at three points then obliquely crosses the sole and inserts in the base of the first metatarsal bone and the plantar aspect of the first cuneiform. MR imaging provides detailed information about the anatomy of tendons in the plantar aspect of the ankle and foot. It allows analysis of their insertions and the intertendinous connection between the flexor hallucis longus and the flexor digitorum longus tendons. (orig.)

    Full Text Available Abstract Introduction Docetaxel is a chemotherapeutic agent used alone or in combination for the management of many neoplastic conditions. Numerous side effects are well described as a consequence. Palmar-plantar erythrodysesthesia, although a relatively common side effect of some types of chemotherapy, occurs infrequently with docetaxel and is often attributed to other drug agents. Case Presentation We report the case of a 66-year-old Caucasian woman who received adjuvant docetaxel monotherapy for invasive breast cancer. She developed palmar-plantar erythrodysesthesia following her first cycle of treatment, which necessitated a change in management. Conclusion Palmar-plantar erythrodysesthesia is a relatively common side effect of cytotoxic chemotherapy, particularly with drugs such as 5-fluorouracil, capecitabine and liposomal doxorubicin. Docetaxel is commonly used both alone and in combination with a number of these agents for the management of various malignant conditions. We would like to highlight the occurrence of palmar-plantar erythrodysesthesia as a result of docetaxel monotherapy so that it can be considered as a potential cause in patients receiving combination treatment with chemotherapeutic agents better known to cause this toxicity.

    Full Text Available OBJECTIVE: To evaluate and compare rearfoot alignment and medial longitudinal arch index during static postures in runners, with and without symptoms and histories of plantar fasciitis (PF. INTRODUCTION: PF is the third most common injury in runners but, so far, its etiology remains unclear. In the literature, rearfoot misalignment and conformations of the longitudinal plantar arch have been described as risk factors for the development of PF. However, in most of the investigated literature, the results are still controversial, mainly regarding athletic individuals and the effects of pain associated with these injuries. METHODS: Forty-five runners with plantar fasciitis (30 symptomatic and 15 with previous histories of injuries and 60 controls were evaluated. Pain was assessed by a visual analogue scale. The assessment of rearfoot alignment and the calculations of the arch index were performed by digital photographic images. RESULTS: There were observed similarities between the three groups regarding the misalignments of the rearfoot valgus. The medial longitudinal arches were more elevated in the group with symptoms and histories of PF, compared to the control runners. CONCLUSIONS: Runners with symptoms or histories of PF did not differ in rearfoot valgus misalignments, but showed increases in the longitudinal plantar arch during bipedal static stance, regardless of the presence of pain symptoms.

    2009-02-01

    Full Text Available OBJECTIVE: To investigate and compare the influence of a previous history of foot ulcers on plantar pressure variables during gait of patients with diabetic neuropathy. INTRODUCTION: Foot ulcers may be an indicator of worsening diabetic neuropathy. However, the behavior of plantar pressure patterns over time and during the progression of neuropathy, especially in patients who have a clinical history of foot ulcers, is still unclear. METHODS: Subjects were divided into the following groups: control group, 20 subjects; diabetic neuropathy patients without foot ulcers, 17 subjects; and diabetic neuropathy patients with at least one healed foot ulcer within the last year, 10 subjects. Plantar pressure distribution was recorded during barefoot gait using the Pedar-X system. RESULTS: Neuropathic subjects from both the diabetic neuropathy and DNU groups showed higher plantar pressure than control subjects. At midfoot, the peak pressure was significantly different among all groups: control group (139.4±76.4 kPa, diabetic neuropathy (205.3±118.6 kPa and DNU (290.7±151.5 kPa (p=0.008. The pressure-time integral was significantly higher in the ulcerated neuropathic groups at midfoot (CG: 37.3±11.4 kPa.s; DN: 43.3±9.1 kPa.s; DNU: 68.7±36.5 kPa.s; p=0.002 and rearfoot (CG: 83.3±21.2 kPa.s; DN: 94.9±29.4 kPa.s; DNU: 102.5±37.9 kPa.s; p=0.048. CONCLUSION: A history of foot ulcers in the clinical history of diabetic neuropathy subjects influenced plantar pressure distribution, resulting in an increased load under the midfoot and rearfoot and an increase in the variability of plantar pressure during barefoot gait. The progression of diabetic neuropathy was not found to influence plantar pressure distribution.

    2015-04-01

    Full Text Available Relevance: Heel pain is one of the most common conditions leading to functional disabilities seen worldwide. There are different methods to manage heel pain, conservatively, and/or surgically. Physiotherapy treatment, as a part of conservative management, involves reduction of pain and improvement of functional ability by various approaches like exercise therapy, electrotherapy and manual therapy techniques. Various studies have shown that Diadynamic current and MENS along with conventional treatments give significant beneficial effects in pain reliving. Hence the present study was undertaken to compare and see the effect of Diadynamic current and MENS in heel pain. Participants: 30 subjects (mean age 25.73 ± 6.56 diagnosed with heel pain were recruited from Out-Patient Department of Physiotherapy of KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belagavi. Method: Subjects were randomly allocated into 2 groups namely Group A (n=15 who received Diadynamic current along with conventional treatment as Therapeutic ultrasound and strengthening and stretching exercises and Group B (n=15 who received MENS with conventional treatment same as in group A for 7 days. The outcome measures were Visual Analog Scale (VAS for pain, Pain disability index (PDI and foot disability index (FDI for functional disability. Analysis: Within group and between group analyses after intervention was done to assess changes using paired t-test and unpaired t - test. Result: Mean difference of VAS scores for Group A was 6.9 ± 1.48 and for Group B was 4.3 ± 2.43. Mean difference of PDI scores for Group A was 274 ± 117 and for Group B was 171 ± 99.Mean difference of FDI scores for Group A was 0.36 ± 0.24 and for Group B was 0.15 ± 0.15. Intra group comparison was statistically significant with p= <0.001 for both the groups in terms of VAS, PDI and FDI respectively. Inter group comparison was statistically significant with p= 0.005, 0.031, 0.007 for VAS, PDI

    2011-07-01

    Objective: The effect of radiotherapy in context of a plantar fasciitis in order to reduce pain was evaluated in this retrospective study. Patients and methods: The data of 188 patients who suffered of heel spur pain and who were irradiated in the period from 1994 to 2009 were evaluated in this study. All of them had at least one follow up examination after radiatiotherapy. The mean age amounted to 57 years. 76.5% of the patients were female. All patients described a local pain which was the basis for the indication. 74.4 % of the patients described pain especially under stress. The duration of anamnesis was averaged as follows: 15 % of the patients had pain for some weeks to 3 months, 43 % for 4 to 6 months, 28% even for 7 to 12 months. The period of medical history was longer than 12 months for 12 % of the patients in this study. 122 of 188 patients received orthopedic arch support (shoe inlays) as first therapy method. Most of the patients were irradiated using regular lateral opposing fields with photons of the energy 4 MV and 6 MV of a linear accelerator, applying a total dose of 6Gy in 6 fractions to 1,0Gy twice weekly. Only one patient was irradiated using a Co{sup 60} machine. The acquisition of data regarding the effect was performed on the last day of the radiotherapy and in 3 to 6 monthly follow ups. Additionally the doctors who attended the patients beyond the radiotherapy received a special questionnaire about the pain reduction, so that the follow up data could be completed. Results: On the last day of radiotherapy 120/188 patients (63,8%)reported an improvement of pain reduction, 7/188 patients (3,7%) absence of pain. For 52/188 patients (27.6 %) pain remained constant. At the second follow up examination after in the median 100 days the effect of radiotherapy of 165 patients could be evaluated, 43/165 patients (26 %) were pain free, 79/165 patients (47,8 %) reported an obvious pain reduction, and for 33/165 patients there was no pain improvement.

    International Nuclear Information System (INIS)

    The purpose of this paper is to evaluate the prospects of using bulk waste characteristics to determine the most appropriate heel retrieval technology. If the properties of hard to remove heels can be determined before bulk retrieval, then a heel retrieval technology can be selected before bulk retrieval is complete. This would save substantially on sampling costs and would allow the deployment of the heel retrieval technology immediately after bulk retrieval. The latter would also accelerate the heel removal schedule. A number of C-farm retrievals have been fully or partially completed at the time of this writing. Thus, there is already substantial information on the success of different technologies and the composition of the heels. There is also substantial information on the waste types in each tank based on historical records. Therefore, this study will correlate the performance of technologies used so far and compare them to the known waste types in the tanks. This will be used to estimate the performance of future C Farm heel retrievals. An initial decision tree is developed and employed on tanks C-101, C-102, and C 111. An assumption of this study is that no additional characterization information would be available, before or after retrieval. Note that collecting additional information would substantially increase the probability of success. Deploying some in-situ testing technologies, such as a water lance or an in-situ Raman probe, might substantially increase the probability of successfully selecting the process conditions without having to take samples from the tanks for laboratory analysis.

    Full Text Available Abstract Background Low-Dye taping is used for excessive pronation at the subtalar joint of the foot. Previous research has focused on the tape's immediate effect on plantar pressure. Its effectiveness following exercise has not been investigated. Peak plantar pressure distribution provides an indirect representation of subtalar joint kinematics. The objectives of the study were 1 To determine the effects of Low-Dye taping on peak plantar pressure immediately post-application. 2 To determine whether any initial effects are maintained following exercise. Methods 12 asymptomatic subjects participated; each being screened for excessive pronation (navicular drop > 10 mm. Plantar pressure data was recorded, using the F-scan, at four intervals during the testing session: un-taped, baseline-taped, post-exercise session 1, and post-exercise session 2. Each exercise session consisted of a 10-minute walk at a normal pace. The foot was divided into 6 regions during data analysis. Repeated-measures analysis of variance (ANOVA was used to assess regional pressure variations across the four testing conditions. Results Reduced lateral forefoot peak plantar pressure was the only significant difference immediately post tape application (p = 0.039. This effect was lost after 10 minutes of exercise (p = 0.036. Each exercise session resulted in significantly higher medial forefoot peak pressure compared to un-taped; (p = 0.015 and (p = 0.014 respectively, and baseline-taped; (p = 0.036 and (p = 0.015 respectively. Medial and lateral rearfoot values had also increased after the second session (p = 0.004, following their non-significant reduction at baseline-taped. A trend towards a medial-to-lateral shift in pressure present in the midfoot immediately following tape application was still present after 20 minutes of exercise.

We wanted to revalidate a 4-item clinical risk score and evaluate a portable heel bone mineral density (BMD technique regarding hip and fragility fracture risk among elderly women. Methods In a population-based prospective cohort study we used clinical risk factors from a baseline questionnaire and heel BMD to predict a two-year hip and fragility fracture outcome for women, in a fracture preventive program. Calcaneal heel BMD was measured by portable dual X-ray laser absorptiometry (DXL and compared to hip BMD, measured with stationary dual X-ray absorptiometry (DXA technique. Results Seven women suffered hip fracture and 14 women fragility fracture/s (at hip, radius, humerus and pelvis among 285 women; 60% having heel BMD ≤ -2.5 SD. The 4-item FRAMO (Fracture and Mortality Index combined the clinical risk factors age ≥80 years, weight Conclusions In a follow-up study we identified high risk groups for hip and fragility fracture with our plain 4-item risk model. Increased fracture risk was also related to decreasing heel BMD in calcaneal bone, measured with a mobile DXL technique. A combination of high FRAMO Index, prior fragility fracture, and very low BMD restricted the high risk group to 11%, among whom most hip fractures occurred (71%. These practical screening methods could eventually reduce hip fracture incidence by concentrating preventive resources to high fracture risk women.

  1. SLUDGE HEEL REMOVAL BY ALUMINUM DISSOLUTION AT SAVANNAH RIVER SITE 12390

    Energy Technology Data Exchange (ETDEWEB)

    Keefer, M.

    2012-01-12

    High Level Waste (HLW) at the Savannah River Site (SRS) is currently stored in aging underground storage tanks. This waste is a complex mixture of insoluble solids, referred to as sludge, and soluble salts. Continued long-term storage of these radioactive wastes poses an environmental risk. Operations are underway to remove and disposition the waste, clean the tanks and fill with grout for permanent closure. Heel removal is the intermediate phase of the waste retrieval and tank cleaning process at SRS, which is intended to reduce the volume of waste prior to treatment with oxalic acid. The goal of heel removal is to reduce the residual amount of radioactive sludge wastes to less than 37,900 liters (10,000 gallons) of wet solids. Reducing the quantity of residual waste solids in the tank prior to acid cleaning reduces the amount of acid required and reduces the amount of excess acid that could impact ongoing waste management processes. Mechanical heel removal campaigns in Tank 12 have relied solely on the use of mixing pumps that have not been effective at reducing the volume of remaining solids. The remaining waste in Tank 12 is known to have a high aluminum concentration. Aluminum dissolution by caustic leaching was identified as a treatment step to reduce the volume of remaining solids and prepare the tank for acid cleaning. Dissolution was performed in Tank 12 over a two month period in July and August, 2011. Sample results indicated that 16,440 kg of aluminum oxide (boehmite) had been dissolved representing 60% of the starting inventory. The evolution resulted in reducing the sludge solids volume by 22,300 liters (5900 gallons), preparing the tank for chemical cleaning with oxalic acid.

  3. Results of Characterization and Retrieval Testing on Tank 241-C-110 Heel Solids

    Energy Technology Data Exchange (ETDEWEB)

    Callaway, William S.

    2013-09-30

    Nine samples of heel solids from tank 241-C-110 were delivered to the 222-S Laboratory for characterization and dissolution testing. After being drained thoroughly, the sample solids were primarily white to light-brown with minor dark-colored inclusions. The maximum dimension of the majority of the solids was <2 mm; however, numerous pieces of aggregate, microcrystalline, and crystalline solids with maximum dimensions ranging from 5-70 mm were observed. In general, the larger pieces of aggregate solids were strongly cemented. Natrophosphate [Na{sub 7}F(PO{sub 4}){sub 2}°19H{sub 2}O] was the dominant solid phase identified in the heel solids. Results of chemical analyses suggested that 85-87 wt% of the heel solids were the fluoridephosphate double salt. The average bulk density measured for the heel solids was 1.689 g/mL; the reference density of natrophosphate is 1.71 g/mL. Dissolution tests on composite samples indicate that 94 to 97 wt% of the tank 241-C-110 heel solids can be retrieved by dissolution in water. Dissolution and recovery of the soluble components in 1 kg (0.59 L) of the heel solids required the addition of ≈9.5 kg (9.5 L) of water at 15 °C and ≈4.4 kg (4.45 L) of water at 45 °C. Calculations performed using the Environmental Simulation Program indicate that dissolution of the ≈0.86 kg of natrophosphate in each kilogram of the tank 241-C-110 heel solids would require ≈9.45 kg of water at 15 °C and ≈4.25 kg of water at 45 °C. The slightly larger quantities of water determined to be required to retrieve the soluble components in 1 kg of the heel solids are consistent with that required for the dissolution of solids composed mainly of natrophosphate with a major portion of the balance consisting of highly soluble sodium salts. At least 98% of the structural water, soluble phosphate, sodium, fluoride, nitrate, carbonate, nitrite, sulfate, oxalate, and chloride in the test composites was dissolved and recovered in the

In the present study, we aimed to examine, using paired comparisons of subjects, whether moderate duration of obesity in patients with mild to moderate elevations of body mass index (BMI), changes the fibrous contents of muscles that support the ankle mortices, namely calf and plantar muscles. We attempted to examine these parameters because this shall provide direct evidence of whether obesity directly impacts myoarchitecture and support of the adjoining joints. MRI image segmentation and pixel correlations by grey level co-occurrence matrix (GLCM) and entropy were used to analyse the changes. The differences in the means between groups (both GLCM and entropy) were significant from control lean populations (Pcalf and the plantar muscles. Reduction in weight should thus be a first-line approach in preventing these changes that may significantly affect quality of life due to gait disturbances. PMID:27380952

    A tip injury of the left thumb was repaired via microsurgical medial plantar flap banking. The medial plantar flap was transferred temporarily to the lower abdominal wall and was anastomosed microsurgically to the deep inferior epigastric artery and vein as a banked flap. It was later grafted to the thumb in a manner similar to a pedicled flap. The flap was transferred successfully, and the tissue texture and bulk was sufficient, with considerable sensory recovery and minimal donor site deformity. This method may be worthwhile to consider as one of the options of digital tip reconstruction, and the concept of microsurgical flap banking may be promising in the field of reconstructive microsurgery.

    Full Text Available Badminton players often perform powerful and long-distance lunges during such competitive matches. The objective of this study is to compare the plantar loads of three one-step maximum forward lunges in badminton.Fifteen right-handed male badminton players participated in the study. Each participant performed five successful maximum lunges at three directions. For each direction, the participant wore three different shoe brands. Plantar loading, including peak pressure, maximum force, and contact area, was measured by using an insole pressure measurement system. Two-way ANOVA with repeated measures was employed to determine the effects of the different lunge directions and different shoes, as well as the interaction of these two variables, on the measurements.The maximum force (MF on the lateral midfoot was lower when performing left-forward lunges than when performing front-forward lunges (p = 0.006, 95% CI = -2.88 to -0.04%BW. The MF and peak pressures (PP on the great toe region were lower for the front-forward lunge than for the right-forward lunge (MF, p = 0.047, 95% CI = -3.62 to -0.02%BW; PP, p = 0.048, 95% CI = -37.63 to -0.16 KPa and left-forward lunge (MF, p = 0.015, 95% CI = -4.39 to -0.38%BW; PP, p = 0.008, 95% CI = -47.76 to -5.91 KPa.These findings indicate that compared with the front-forward lunge, left and right maximum forward lunges induce greater plantar loads on the great toe region of the dominant leg of badminton players. The differences in the plantar loads of the different lunge directions may be potential risks for injuries to the lower extremities of badminton players.

    Full Text Available Background/Aim : Intralesional bleomycin gained increasing popularity in the recent past for treatment of warts particularly in palmo-plantar and periungual regions as other modalities are not very effective. Hence we evaluated the role of intralesional bleomycin in periungual and palmo-plantar warts to know its efficacy in Indian patients. Settings and Design : This was a placebo-controlled study. Materials and Methods : Fifty patients of multiple palmo-plantar and periungual warts were included in this study and categorized in groups A and B of 25 each. Alternate patients were included in groups A and B and treated respectively with intralesional bleomycin (1 mg/mL solution and normal saline as placebo, fortnightly for maximum up to two injections. Patients were followed up weekly for 1 month, fortnightly up to 12 weeks, and then quarterly for 1 year. If warts persisted after 12 weeks of starting treatment, it was considered a failure. Statistical analysis was done by the chi-square test using M-stat software. Results : Group A and B patients were having 85 warts and 72 warts, respectively. The cure rate in group A and B patients was 96.47% (82/85 warts and 11.11% (8/72 warts, respectively, after one or two injections within 12 weeks. The difference in the cure rate between two groups was statistically highly significant (<0.0001. In group A patients, a haemorrhagic eschar was formed which gradually healed in 8-12 weeks without atrophy or pigmentation; this phenomenon was not seen in group B. Only moderate pain was observed by most of the patients during injection in both groups. Conclusion : The intralesional injection of bleomycin is highly effective, safe, and non-toxic in periungual and palmo-plantar warts.

    Pressure-sensitive measuring devices have been identified as appropriate tools for measuring an array of parameters during running. It is unclear which biomechanical characteristics relate to running-related injury (RRI) and which data-processing techniques are most promising to detect this relationship. This systematic review aims to identify pertinent methodologies and characteristics measured using plantar pressure devices, and to summarise their associations with RRI. PubMed, Embase, CINAHL, ScienceDirect and Scopus were searched up until March 2015. Retrospective and prospective, biomechanical studies on running using any kind of pressure-sensitive device with RRI as an outcome were included. All studies involving regular or recreational runners were considered. The study quality was assessed and the measured parameters were summarised. One low quality, two moderate quality and five high quality studies were included. Five different subdivisions of plantar area were identified, as well as five instants and four phases of measurement during foot-ground contact. Overall many parameters were collated and subdivided as plantar pressure and force, plantar pressure and force location, contact area, timing and stride parameters. Differences between the injured and control group were found for mediolateral and anteroposterior displacement of force, contact area, velocity of force displacement, relative force-time integral, mediolateral force ratio, time to peak force and inter-stride correlative patterns. However, no consistent results were found between studies and no biomechanical risk patterns were apparent. Additionally, conflicting findings were reported for peak force in three studies. Based on these observations, we provide suggestions for improved methodology measurement of pertinent parameters for future studies. PMID:27264395

    2013-01-01

    Full Text Available Background. The wearing of personal equipment can cause specific changes in muscle activity and posture. In the present study, we investigated the influence of differences in equipment related weight loading and load distribution on plantar pressure. In addition, we studied functional effects of wearing different equipment with a particular focus on relevant changes in foot shape. Methods. Static and dynamic pedobarography were performed on 31 male soldiers carrying increasing weights consisting of different items of equipment. Results. The pressure acting on the plantar surface of the foot increased with higher loading, both under static and dynamic conditions (p < 0.05. We observed an increase in the contact area (p < 0.05 and an influence of load distribution through different ways to carry the rifle. Conclusions. The wearing of heavier weights leads to an increase in plantar pressure and contact area. This may be caused by flattening of the transverse and longitudinal arches. The effects are more evident in subjects with flat feet deformities which seem to flatten at an earlier load condition with a greater amount compared to subjects with normal arches. Improving load distribution should be a main goal in the development of military equipment in order to prevent injuries or functional disorders of the lower extremity.

    Full Text Available OBJECTIVE: To compare radial shockwave treatment with conventional physiotherapy for plantar fasciitis after 12 months of follow-up. METHOD: This was a randomized, prospective, comparative clinical study. Forty patients with a diagnosis of plantar fasciitis were divided randomly into two treatment groups: group 1, with 20 patients who underwent ten physiotherapy sessions comprising ultrasound, kinesiotherapy and guidance for home-based stretching; and group 2, with 20 patients who underwent three applications of radial shockwaves, once a week, and guidance for home-based stretching. All patients were assessed regarding pain and functional abilities before treatment, immediately after and 12 months after treatment. The mean age was 49.6 ±11.8 years (range: 25-68 years, 85% were female, 88% were overweight, 63% were affected bilaterally, and 83% used analgesics regularly. RESULTS: At the 12-month follow-up, both treatments were effective for improving pain and functional ability among the patients with plantar fasciitis. The improvement with shockwaves was faster. CONCLUSION: Shockwave treatment was not more effective than conventional physiotherapy treatment 12 months after the end of the treatment.

    Full Text Available Foot orthoses and night splints have been used separately to treat patients with plantar fasciitis, but were not always successful. Combined use of both orthoses might give better outcomes. This study evaluated the effectiveness of a soft and self-adjustable dorsiflexion night splint in combination with an accommodative foot orthosis for patients with plantar fasciitis. Twenty-eight patients were assigned to group A (foot orthosis only and group B (combination of foot orthosis and dorsiflexion night splints. A Foot Function Index (FFI questionnaire was used to evaluate the pain and functions of feet just before, 2 weeks after, and 8 weeks after the treatments. Results showed that subjects in group B had significantly reduced pain scores at week 2 (p < 0.001 and week 8 (p < 0.001. In group A, no statistical differences were noted in the pain (p = 0.15, disability (p = 0.56, activity limitation (p = 0.75, and total FFI (p = 0.35 scores for the three time periods. The application of foot orthoses with adjustable dorsiflexion night splints was found to be more effective than the application of foot orthoses alone in relieving foot pain in patients with plantar fasciitis.

    The purpose of the work reported here was to describe the sonoelastographic appearance of the plantar fascia of healthy volunteers and patients with fasciitis. Twenty-three healthy subjects and 21 patients with plantar fasciitis were examined using B-mode and real-time sonoelastography (RTSR) scanning. B-Mode examination included fascia thickness and echotexture. Echogenicity and echovariation of the color histogram were analyzed. Fasciae were classified into type 1, blue (more elastic); type 2, blue/green (intermediate); or type 3, green (less elastic). RTSE revealed 72.7% of fasciae as type 2, with no significant association with fasciitis (χ(2) = 3.6, df = 2, p = 0.17). Quantitative analysis of the color histogram revealed a significantly greater intensity of green (mean = 77.8, 95% confidence interval [CI] = 71.9-83.6) and blue (mean = 74.2, 95% CI = 69.7-78.8) in healthy subjects. Echovariation of the color red was 33.4% higher in the fasciitis group than in the healthy group (95% CI = 16.7-50.1). Sonoelastography with quantitative analysis of echovariation can be a useful tool for evaluation of plantar fascia pathology. PMID:26164287

    Dactylitis is a common feature of psoriatic arthritis (PsA); local physical trauma has been identified as a possible contributing factor. The aim of this study was to explore differences in forefoot plantar pressures in patients with PsA with and without dactylitis and compare to healthy controls. Thirty-six participants were recruited into three groups: group A PsA plus a history of dactylitis; group B PsA, no dactylitis; group C control participants. Forefoot plantar pressures were measured barefoot and in-shoe at the left second and fourth toes and corresponding metatarsophalangeal joints. Temporal and spatial parameters were measured and data from the foot impact scale for rheumatoid arthritis (FIS-RA), EQ5D and health assessment questionnaire (HAQ) were collected. Pressure time integral peak plantar pressure, and contact time barefoot and in-shoe were not significantly different between groups. Temporal and spatial parameters reported no significant differences between groups. ANOVA analysis and subsequent post hoc testing using Games-Howell test yielded significance in FIS-RA scores between both PsA groups versus controls, A p ≤ 0.0001 and PsA group B p history of dactylitis does not appear to worsen patient reported outcomes.

    Full Text Available A 68-year-old man, a known case of hypertension, coronary artery disease and old cardiovascular accident with right-sided hemiplegia, came with the chief complaints of a large cauliflower like growth with pus discharge on the left heel since 15 years. The patient had sustained a penetrating injury by a thorn on the left heel region few days before the lesion appeared. Dermatological examination revealed a single verrucous lesion measuring 7 × 7 cm on the left heel region associated with discharge of foul smelling cheesy material. There was also a enlarged right inguinal lymph node which was non-tender, firm, measuring 2 cm in diameter with normal overlying skin. X-ray left ankle was done which showed some soft tissue swelling. A skin biopsy showed hyperkeratosis, acanthosis and parakeratosis. Elongated rete ridges with keratinocyte hyperplasia, forming a large mass pressing on the underlying dermis were seen. There was formation of multiple large keratin filled invaginations and crypts. No atypical cells were seen. Based on history, clinical examination and investigations, a diagnosis of epithelium cuniculatum type of verrucous squamous cell carcinoma was made. A wide excision with a flap cover was performed in consultation with the oncosurgeon and the excision sample was sent for histopathological re-examination, which confirmed the diagnosis of epithelioma cuniculatum.

  2. Estimation of the carcinogenic risk of radiotherapy of benign diseases from shoulder to heel

    International Nuclear Information System (INIS)

    Background and purpose: To estimate risk on fatal tumour induction in patients by radiotherapy of benign diseases at various body sites, including heterotopic ossification, omarthritis, gonarthrosis, heel spurs and hidradenitis suppurativa. Material and methods: The carcinogenic risk is estimated by applying the effective dose concept from the ICRP with the average risk factor of 10% per Sv for high dose and high dose rate. Although, the concept of effective dose for the present study has limitations, its use is considered acceptable for a fairly rough risk estimate. The organ doses are calculated using a Monte Carlo radiation transport code and anthropomorphic mathematical phantoms. Special risk modifying factors like patient's age at exposure and gender are taken into account. Results: For the treatment of heterotopic ossification, omarthritis, gonarthrosis, heel spurs and hidradenitis suppurativa the effective dose is in the range of 5-400 mSv. For an average-aged population, the estimated number of radiation-induced fatal tumours due to these treatments is assessed to be between 0.5 and 40 persons per 1000 patients treated. At higher ages the risks are reduced. Conclusions: The range of effective doses found for the various types of treatment at various body sites is large. There are several possibilities to optimise the treatment protocols resulting in reduced effective doses and related radiation risks

    Highlights: •We evaluate the accuracy of ultrasound to identify and measure the plantar plate. •We correlate ultrasound findings with those of physical examination and MRI. •Ultrasound and MRI measures of plantar plate were positively correlated. •Ultrasound is efficient in identifying and measuring plantar plate. •Ultrasound may complement physical examination. •Young asymptomatic subjects can present a grade I positive drawer test. -- Abstract: Objectives: The aims of this study were (1) to evaluate the reliability of ultrasound (US) examination in the identification and measurement of the metatarsophalangeal plantar plate (MTP-PP) in asymptomatic subjects and (2) to establish the correlation of US findings with those of physical examination and magnetic resonance imaging (MRI), once it is an important tool in the evaluation of the instability syndrome of the second and third rays. Materials and Methods: US examinations of the second and third MTP-PPs were performed in eight asymptomatic volunteers, totaling 32 MTP joints, by three examiners with different levels of experience in musculoskeletal US. Plantar plate dimensions, integrity and echogenicity, the presence of ruptures, and confidence level in terms of structure identification were determined using conventional US. Vascular flow was assessed using power Doppler. US data were correlated with data from physical examination and MRI. Results: MTP-PPs were ultrasonographically identified in 100% of cases, always showing homogeneous hyperechoic features and no detectable vascular flow on power Doppler, with 100% certainty in identification for all examiners. There was excellent US inter-observer agreement for longitudinal measures of second and third toe MTP-PPs and for transverse measures of the second toe MTP-PP. The MTP drawer test was positive for grade 1 MTP instability in 34.4% of joints with normal US results. Transverse MTP-PP measures were significantly higher in individuals with positive

    The aims were to describe the behavior of the subtalar joint and foot in the race walk, and seek for correlations between them and the footprint. 12 race walkers participated in the study. The arch index was calculated on their footprints. Plantar pressures were measured and 3D photogrammetry used on a single support while they race walked at their own competitive speed. Maximum pressures were calculated in each region of the foot and also the maximum and minimum values of the three angles that describe the subtalar joint. The maximum pronation was higher than that described in the walking gait and similar to that of the running gait (-13.6 ± 3.90. In the beginning of the support the subtalar joint was between the walking and the running gaits. This suggests that the cushioning mechanism of this joint is adjusted according to the type of locomotion. The region of the foot that registered higher pressures was the external rearfoot (21.02 kPa/kg followed by the internal forefoot (13.12 kPa/kg, showing a different behaviour to that of the running gait, in which both present similar maximum pressures. The subjects with lower arches tended to support with the internal face of the foot (r=-0.713 and with the leg inclined medially (r=0.874. Likewise, the racewalkers with higher arches registered higher pressures in the external part of the rearfoot, whereas the lowest ones did it in the internal part of the midfoot.
    Key Words: Biomechanics, race walk, footprint, subtalar joint, plantar pressure.

En el grupo de laserterapia, se demuestra la efectividad de este método, debido a que la desviación promedio de laserterapia (0,683 se aparta menos de la media que la desviación promedio de acupuntura (0,882. Recomendamos el uso de láser de baja potencia, como tratamiento de primera línea para el manejo de condiciones álgicas e inflamatorias asociadas al espolón calcáneo.Introduction: Physical Medicine and Rehabilitation and Traditional and Natural Medicine are medical specialties that develop measures for the promotion of health, prevention, diagnosis and treatment, using physiotherapy and natural agents, along with acupuncture and therapeutic laser. The heel spur is an osteophyte that grows in the front part of the plantar tuberosity of the heel bone secondary to inflammatory processes of a degenerative cause or of immune origin associated with the spondyloarthropathies. It is mainly diagnosed by clinical examination, x-ray studies and ultrasound. The most important symptom is the pain and the treatment is almost always conservative, although other therapeutic agents can be employed. Objective: We studied the analgesic effect obtained by the application of an infrared laser radiation in patient suffering from heel spur. Methods: The investigation consisted of a comparative, descriptive, and prospective study. Of a total of 62 patients who attended the Department of Traditional and Natural Medicine of the November 30th University Polyclinic, in the period of January 2005 to January 2008, 52 patients were formed into 2 groups of 26. One group had lasertherapy and the other acupuncture treatment. Patients of both sexes and of any race were included, and ages ranged from 20 to 80 years. We excluded pregnant women and patients with cancer. The pain intensity was measured in all of them using the visual analog scale (VAS

    Eight samples of heel solids from tank 241-C-109 were delivered to the 222-S Laboratory for characterization and dissolution testing. After being drained thoroughly, one-half to two-thirds of the solids were off-white to tan solids that, visually, were fairly evenly graded in size from coarse silt (30-60 μm) to medium pebbles (8-16 mm). The remaining solids were mostly strongly cemented aggregates ranging from coarse pebbles (16-32 mm) to fine cobbles (6-15 cm) in size. Solid phase characterization and chemical analysis indicated that the air-dry heel solids contained ≈58 wt% gibbsite [Al(OH){sub 3}] and ≈37 wt% natrophosphate [Na{sub 7}F(PO{sub 4}){sub 2}·19H{sub 2}O]. The strongly cemented aggregates were mostly fine-grained gibbsite cemented with additional gibbsite. Dissolution testing was performed on two test samples. One set of tests was performed on large pieces of aggregate solids removed from the heel solids samples. The other set of dissolution tests was performed on a composite sample prepared from well-drained, air-dry heel solids that were crushed to pass a 1/4-in. sieve. The bulk density of the composite sample was 2.04 g/mL. The dissolution tests included water dissolution followed by caustic dissolution testing. In each step of the three-step water dissolution tests, a volume of water approximately equal to 3 times the initial volume of the test solids was added. In each step, the test samples were gently but thoroughly mixed for approximately 2 days at an average ambient temperature of 25 °C. The caustic dissolution tests began with the addition of sufficient 49.6 wt% NaOH to the water dissolution residues to provide ≈3.1 moles of OH for each mole of Al estimated to have been present in the starting composite sample and ≈2.6 moles of OH for each mole of Al potentially present in the starting aggregate sample. Metathesis of gibbsite to sodium aluminate was then allowed to proceed over 10 days of gentle mixing of the

    Full Text Available Although biofeedback systems have been used to improve balance with success, they were confined to hospital training applications. Little attempt has been made to investigate the use of in-shoe plantar force measurement and wireless technology to turn hospital training biofeedback systems into wearable devices. This research developed a wearable biofeedback system which detects body sway by analyzing the plantar force and provides users with the corresponding haptic cues. The effects of this system were evaluated in thirty young and elderly subjects with simulated reduced foot sensation. Subjects performed a Romberg test under three conditions: (1 no socks, system turned-off; (2 wearing five layers of socks, system turned-off; (3 wearing five layers of socks, and system turned-on. Degree of body sway was investigated by computing the center of pressure (COP movement measured by a floor-mounted force platform. Plantar tactile sensation was evaluated using a monofilament test. Wearing multiple socks significantly decreased the plantar tactile sensory input (p < 0.05, and increased the COP parameters (p < 0.017, indicating increased postural sway. After turning on the biofeedback system, the COP parameters decreased significantly (p < 0.017. The positive results of this study should inspire future development of wearable plantar force-based biofeedback systems for improving balance in people with sensory deficits.

    Functional and esthetic reconstruction of the bony and tendinous structures with a stable, sensate soft tissue integument after complex posttraumatic defects of the heel is demanding. Cases are rare in the literature and hardly comparable due to their heterogeneity. The reconstructive approach has to consider both patient profile and the reconstructive tree, with free microvascular flaps playing a primary role. The goals are the reconstruction of both osteotendinous structures and slender soft tissue lining for proper shoe fitting for ambulation and mechanical and thermal protection. The flap should be sensate in weightbearing areas to optimize gait and to prevent long-term complications by ulcers. The osteofasciocutaneous deep inferior circumflex artery (DCIA) flap is especially suitable for complex heel defects with subtotal or total loss of the calcaneal bone as all components (iliac bone, groin skin, and fascia lata) can have a wide range of size and shape. We operated on 2 cases with this variable composite flap. One patient had a complete heel defect by war shrapnel. The complete calcaneus, soft heel, and Achilles tendon were reconstructed. The second patient had an empty os calcis after a comminuted fracture and a lateral crush-induced soft tissue defect. In both patients, a stable wound closure, osseous integration, and weightbearing ambulation could be achieved. PMID:16721075

    2016-01-01

    Middle East Respiratory Syndrome (MERS) coronavirus is the most recent among the Coronaviridae family to jump species and infect humans. Major healthcare associated MERS outbreaks have occurred in the Middle East and Korea that affected both patients and healthcare workers. These outbreaks were characterized by intra and inter-hospital spread and were exacerbated specifically by overcrowding, delayed diagnosis and appropriate use of personal protective equipment. Recent experience with this virus emphasizes the importance of compliance with infection control practices and with other interventions addressing patient triage, placement and flow within and between healthcare facilities. Our Achilles heel remains compliance with the best infection prevention practices and their harmonization with patient flow. Both infection prevention compliance and maintenance of patient flow are critical in preventing healthcare-associated transmission of many of these emerging infectious diseases, including MERS.

    Full Text Available Surface-mounted accelerometers (SMA secured tightly to body segments with an elastic strap, are commonly used to quantify the impact response of bone.  However, the effect that this type of fixation has on segment soft tissue motion relative to bone has yet to be determined.  Heel impacts were collected from 20 participants using a human pendulum apparatus, with (strap and without (no strap a SMA attached to the proximal tibia.  Leg soft tissue motion was quantified using digital image analysis software which monitored positions of skin markers from a series of high speed photographs.  The strap was found to alter the natural physiological motion of the soft tissue, with significant displacement, velocity and sex differences occurring within the most proximal regions.  Future research should evaluate alternative methods for quantifying bone and soft tissue response to impact concurrently, to advance our understanding of impact-related injury mechanisms.

  14. In vivo and in vitro testing of shoe heel insert properties; a comparative study

    International Nuclear Information System (INIS)

    Shoe heel inserts (SHI) are a common method of conservative treatment for various painful disorders like degenerative joint diseases (010) and overuse injuries. They are also used to enhance exercise performance in athletes. There is little in the literature to guide orthopaedic practitioners in relation to optimum material for these SHI. The current study examines properties of three different kinds of off-the-shelf SHI in terms of their performance, endurance and cost. The material properties of inserts were tested on a universal material testing machine (UTM) before and after mechanical degradation (MO) that was performed by a purpose built repetitive loading machine (RLM) under compression and shearing forces. The results of material. tests were augmented through subject tests by a pressure sensitive insole system, Pedar. The data provided evidence that MO, simulating a normal walking distance of 100 to 130 Km, deteriorated the performance of all inserts tested in the current study. There were significant changes in the stiffness and elastic hysteresis of inserts and they were less efficient in cushioning heel areas. The SHI were responsible for putting more pressure under the lateral metatarsal heads. The SHI may be effective in symptomatic relief of painful 010 and overuse injuries but should be used cautiously in diabetic patients.

    2007-09-01

    The aim of the study was to document soft tissue vascularization of the lateral heel on cadavers and, therefore, to indirectly demonstrate the importance to perform perfectly precise incisions, in order to prevent ischemic complications. Sections of 8 human lower limb cadavers were performed in cooperation with the Anatomical Institute of the MU Medical Faculty in Brno, according to current common standards for anatomical preparations. In successive steps, cutaneous and subcutanous covers of the lateral ankle, malleolar and heel regions were preparated. Final branches of the individual arteries were followed and the authors aimed to demonstrate their vascular arcade consisting of anastomosis of the lateral calcaneal artery--LCA (a branch of a. peronea)--which is a clinical term for rami calcaneares laterales, ventrolateral tarsal arteries--LTA (a branch of a. dorsalis pedis) and lateral malleolar artery branching off medially--LMA (a branch of a. tibialis ant.). The course of the arteries and their location is related to a reference point--a lateral tip of the lateral ankle. The investigators found out that all three arteries, as well as the arterial arch, had standard courses. The course of the arch defines the outline of the lateral extensive incision during osteosynthesis in calcaneal fractures, which lies fairly close to the lateral outline of this vascular arcade. Incorrect performance of the incision results, invitably, in serious ischemic complications. Open reduction and internal fixation of intraarticular calcaneal fractures has become a standard surgical method. Correct indication, good timing and saving open reduction, internal fixation using arthroscopy and early mobilization are the prerequisites to prevent further postoperative complications and to achieve complete healing of the fracture. Considering the demandingness of these fractures treatment and their rare incidence, their management should be centred in specialized traumatological clinics. PMID

    A major goal of therapeutic footwear in patients with pain or those at risk for skin injury is to relieve focal loading under prominent metatarsal heads. One frequent approach is to place plugs of compliant material into the midsole of the shoe. This study investigated 36 plug designs, a combination of three materials, six geometries, and two placements using a two-dimensional (2D) finite element model. Realistic loading conditions were obtained from plantar pressures (PP) recorded during walking in five subjects who wore control midsoles manufactured using Microcell Puff. Measured peak pressures underneath the second metatarsal head were similar to the results of the control model. PP obtained from simulations with the plugs built into a firm midsole were compared to the simulation results of the control midsole. Large plugs (e.g. 40 mm width), made out of Microcell Puff Lite or Plastazote Medium, placed at peak pressure sites, resulted in highest reductions in peak pressures (18-28%). Smaller plugs benefited from tapering when placed at high pressure areas. Case studies were completed on a healthy male subject and a diabetic female patient to address the efficacy of a plug design favored by our simulations (pressure based placement, 40 x 20 mm, Plastazote Medium). Successful reductions of second metatarsal head pressures were observed with a mediolateral load redistribution that was not represented by our model. 2D computer simulations allowed systematic investigation of plug properties without the need for high volume experimentation on human subjects and established basic guidelines for plug selection. In particular, plugs that are placed based on plantar pressure measurements were proven to be more effective when compared to those positioned according to the projection of the bony landmark on the foot-shoe plantar contact area.

    Foot pain frequently reduces physical activity and increases the risk of falls in older people. In current orthotic management of forefoot pain, metatarsal padding is the main strategy to reduce metatarsal pressure. However, pressure reductions are usually diverse and limited. The multi-step accommodative insole is fabricated by sequential foam padding on Plastazote under dynamic accommodation in daily walking. The aims of this study were to investigate the effectiveness and mechanisms of accommodative insole on plantar pressure redistribution in older people with metatarsalgia. The study was conducted on 21 old outpatients with moderate to severe metatarsalgia, using the ethylene vinyl acetate control, 9-mm flat Plastazote, and accommodative insoles with and without metatarsal and arch support. Outcome measures included pressure-related variables measured by a Pedar-X system, and pain scores assessed with a 0-10 Visual Analog Scale. The accommodative insole significantly decreased peak pressure under the metatarsal heads by 47.2% (p<0.001) and the pain scores from 8.2 to 1.1 (p<0.001). Plantar pressure analyses indicated that the effects of dynamic metatarsal contouring and cushioning on reducing peak pressure were greater than those of metatarsal padding. The temporo-spatial relationships between the toe and metatarsal head can assist in explaining an elevated metatarsal pressure and higher risk of falls in older people with toe deformities. The multi-step insole is simple in orthotic fabrication and ensures an even distribution of plantar pressure loading in walking. It can effectively relieve metatarsalgia and help to preserve regular walking activity for older people with metatarsalgia. PMID:24119776

  18. Neuromuscular function and fatigue resistance of the plantar flexors following short-term cycling endurance training

    Full Text Available Previously published studies on the effect of short-term endurance training on the neuromuscular function of the plantar flexors have shown that the H-reflex elicited at rest and during weak voluntary contractions was increased following the training regime. However, these studies did not test H-reflex modulation during isometric maximum voluntary contraction (iMVC and did not incorporate a control group in their study design to compare the results of the endurance training group to individuals without the endurance training stimulus. Therefore, this randomized controlled study was directed to investigate the neuromuscular function of the plantar flexors at rest and during iMVC before and after eight weeks of cycling endurance training. Twenty-two young adults were randomly assigned to an intervention group and a control group. During neuromuscular testing, rate of torque development, isometric maximum voluntary torque and muscle activation were measured. Triceps surae muscle activation and tibialis anterior muscle co-activation were assessed by normalized root mean square of the EMG signal during the initial phase of contraction (0-100, 100-200 ms and isometric maximum voluntary contraction of the plantar flexors. Furthermore, evoked spinal reflex responses of the soleus muscle (H-reflex evoked at rest and during iMVC, V-wave, peak twitch torques induced by electrical stimulation of the posterior tibial nerve at rest and fatigue resistance were evaluated. The results indicate that the endurance training did not lead to a significant change in any variable of interest. Data of the present study conflict with the outcome of previously published studies that have found an increase in H-reflex excitability after endurance training. However, these studies had not included a control group in their study design as was the case here. It is concluded that short-term cycling endurance training does not necessarily enhance H-reflex responses and fatigue

    The neuromuscular adaptations in response to muscle stretch training have not been clearly described. In the present study, changes in muscle (at fascicular and whole muscle levels) and tendon mechanics, muscle activity, and spinal motoneuron excitability were examined during standardized plantar flexor stretches after 3 wk of twice daily stretch training (4 × 30 s). No changes were observed in a nonexercising control group (n = 9), however stretch training elicited a 19.9% increase in dorsiflexion range of motion (ROM) and a 28% increase in passive joint moment at end ROM (n = 12). Only a trend toward a decrease in passive plantar flexor moment during stretch (-9.9%; P = 0.15) was observed, and no changes in electromyographic amplitudes during ROM or at end ROM were detected. Decreases in H(max):M(max) (tibial nerve stimulation) were observed at plantar flexed (gastrocnemius medialis and soleus) and neutral (soleus only) joint angles, but not with the ankle dorsiflexed. Muscle and fascicle strain increased (12 vs. 23%) along with a decrease in muscle stiffness (-18%) during stretch to a constant target joint angle. Muscle length at end ROM increased (13%) without a change in fascicle length, fascicle rotation, tendon elongation, or tendon stiffness following training. A lack of change in maximum voluntary contraction moment and rate of force development at any joint angle was taken to indicate a lack of change in series compliance of the muscle-tendon unit. Thus, increases in end ROM were underpinned by increases in maximum tolerable passive joint moment (stretch tolerance) and both muscle and fascicle elongation rather than changes in volitional muscle activation or motoneuron pool excitability.

  3. Integrating computer aided radiography and plantar pressure measurements for complex gait analysis

    International Nuclear Information System (INIS)

    Radiographic Fluoroscopy (DRF) and Contact Pressure Display (CPD). The CPD method uses a birefiingent integrated optical sandwich for contact stress analysis, e.g. plantar pressure distribution. The DRF method displays and electronically records skeletal motion using X-ray radiation, providing the exact bone and joint positions during gait. Integrating the two techniques, contribution of each segment to the HFS behavior may be studied by applying image processing and analysis techniques. The combined resulted data may be used not only to detect and diagnose gait pathologies but also as a base for development of advanced numerical models of the foot structure

    Full Text Available Na prática fisioterapêutica, pressupõe-se que alterações posturais do membro inferior influenciem a biomecânica e função dos demais complexos durante o movimento. No entanto, a literatura sobre a relação entre desalinhamentos estáticos do joelho e possíveis alterações dinâmicas ainda é escassa e inconclusiva. Assim, buscou-se avaliar o efeito do alinhamento frontal estático do joelho sobre a distribuição da pressão plantar durante a marcha. Foram avaliados inicialmente 44 adultos jovens assintomáticos. Por fotogrametria digital, mediu-se o ângulo frontal do joelho, classificado como normal (170° a 175°, valgo 175°. Dado o baixo número de valgos, foram analisados dois grupos: de joelhos normais (n=18 e de joelhos varos (n=23. A distribuição da pressão plantar foi avaliada durante a marcha em cinco áreas. Os grupos mostraram-se estatistica-mente semelhantes em todas as variáveis cinéticas avaliadas em todas as áreas plantares. Joelhos normais apresentaram significativa correlação com o tempo de contato no antepé lateral e médio-pé; e os varos, correlação com a área e tempo de contato em duas e três áreas plantares, e com a pressão integral no antepé lateral. Os resultados mostraram que o desalinhamento frontal de 3° do joelho, embora com moderada correlação, não influencia a distribuição de cargas na superfície plantar durante a marcha. Sugere-se pois que a avaliação clínica não se limite à avaliação articular estática do joelho, mas inclua atividades dinâmicas.In physical therapy practice, it is assumed that lower-limb posture changes may influence other complexes' biomechanics or function during movement. However, literature on the relationship between static knee alignment and possible dynamic changes is still scarce and inconclusive.

    [Objective] To discuss the clinical curative effect of minimal invasion surgery for heel pain in elderly patients (age ≥60 years) with calcaneal tubercle osteophyte. [Methods] From July 2000 to July 2010, the surgical methods and clinical curative effect were analyzed in 159 cases ( 173 feet) of heel pain with calcaneal lubercle osteophyle. According to the Maryland scoring system, all the cases were < 50 scores before surgery. Minimally invasive removal of osteophytes, the release of plantar fascia insertion and bursa surgery were operated in 57 feet (minimal invasion group) , while other 47 feet received open surgery ( open group) . [ Results] A total of 93 cases (104 feet) obtained a mean of 19 months follow up. In minimal invasion group, the pain was completely relieved without walking effect in 55 feet. Other 2 feet also improved pain relief significantly, but the pain was residual after severe activity, which can be relieved by rest. In open group, the pain was completely relieved without walking effect in 45 feet. One foot improved pain relief significantly, but the pain was residual after severe activity, which can be relieved by rest. One foot suffered from scarring pain for six months, which disappeared after the softening of the scar. [Conclusion] For the heel pain with calcaneal tubercle osteophyte, it can obtain good clinical curative effect by releasing the plantar fascia insertion and removing the osteophytes and bursa both in minimal invasion surgery and open surgery. Compared with the open surgery, the minimal invasion surgery can be acceptable easily for ihe less invasion and faster recovery.%[目的]探讨老年(年龄≥60岁)跟骨结节骨赘型跟痛症微创治疗的临床疗效.[方法]对2000年7月~2010年7月本院治疗的159例(173足)跟骨结节骨赘型跟痛症老年患者的手术方式及疗效进行分析.根据Maryland 评分患者均<50分,其中82足(微创组)患者接受了微创骨赘切除、跖腱膜止

  6. Clinical importance of CT-assisted sympathicolysis in primary, focal plantar and palmar hyperhidrosis

    International Nuclear Information System (INIS)

    Purpose: The objective of this study was to evaluate the benefit of thoracic and lumbar computed tomographic-assisted sympathicolysis (CTSy) in patients with primary, focal hyperhidrosis. Materials and Methods: Thoracic and/or lumbar CTSy was conducted on 101 patients (average age 37.5 ± 15.5 years) with primary, focal hyperhidrosis of the hands and/or feet, who experienced persistent symptoms after all conservative treatment options had been exhausted. The patients were divided into groups with palmar, palmoplantar and plantar hyperhidrosis. The patients evaluated the severity of their symptoms prior to the intervention and 2 days, 6 months and 12 months after the intervention using a Dermatology Quality of Life Index (DLQI) and side effects. Results: The performed interventions led to a statistically significant decrease in the preinterventional severity of symptoms after the intervention (2 days), and 6 and 12 months after CTSy in the palmar, palmoplantar and plantar (p < 0.01) group. The technical success rate of CTSy was 100 %. No major complications occurred. Patients reported compensatory perspiration over the course of treatment, neuralgia and paraesthesia as side effects. The differentiated assessment of the strength of perspiration of the hands and feet showed statistically significant differences between the foot and hand region, whereby the decrease in sweat secretion of the feet was more significant and more lasting (p < 0.02). Conclusion: After conservative measures have been exhausted, CT-assisted sympathicolysis represents a therapeutic option with minimal side effects for patients with primary, focal hyperhidrosis.

    2016-01-01

    This study aimed to determine the relative and absolute reliability of ultrasound (US) measurements of the thickness and echogenicity of the plantar fascia (PF) at different measurement stations along its length using a standardized protocol. Twelve healthy subjects (24 feet) were enrolled. The PF was imaged in the longitudinal plane. Subjects were assessed twice to evaluate the intra-rater reliability. A quantitative evaluation of the thickness and echogenicity of the plantar fascia was performed using Image J, a digital image analysis and viewer software. A sonography evaluation of the thickness and echogenicity of the PF showed a high relative reliability with an Intra class correlation coefficient of ≥0.88 at all measurement stations. However, the measurement stations for both the PF thickness and echogenicity which showed the highest intraclass correlation coefficient (ICCs) did not have the highest absolute reliability. Compared to other measurement stations, measuring the PF thickness at 3 cm distal and the echogenicity at a region of interest 1 cm to 2 cm distal from its insertion at the medial calcaneal tubercle showed the highest absolute reliability with the least systematic bias and random error. Also, the reliability was higher using a mean of three measurements compared to one measurement. To reduce discrepancies in the interpretation of the thickness and echogenicity measurements of the PF, the absolute reliability of the different measurement stations should be considered in clinical practice and research rather than the relative reliability with the ICC.

    Twelve chronic hemiparetic outpatients with pronounced lower limb extensor spasticity were injected with 400 units of botulinum toxin A, EMG guided into the soleus, tibialis posterior, and both heads of the gastrocnemius muscles. Botulinum toxin A caused a definite reduction of plantar flexor spasticity, in 10 patients two weeks after the injection, as assessed by the Ashworth scale. Four of the patients were able to achieve active dorsiflexion of their affected ankle. Gait analysis including...

    In diabetic patients, excessive peak plantar pressure has been identified as major risk factor for ulceration. Analyzing plantar pressure distributions potentially improves the identification of patients with a high risk for foot ulceration development. The goal of this study was to classify regional plantar pressure distributions. By means of a sensor-equipped insole, pressure recordings of healthy controls (n = 18) and diabetics with severe polyneuropathy (n = 25) were captured across eight foot regions. The study involved a controlled experimental protocol with multiple sessions, where a session contained several cycles of pressure exposure. Clustering was used to identify subgroups of study participants that are characterized by similar pressure distributions. For both analyzed groups, the number of clusters to best describe the pressure profiles was four. When both groups were combined, analysis again led to four distinct clusters. While three clusters did not separate between healthy and diabetic volunteers the fourth cluster was only represented by diabetics. Here the pressure distribution pattern is characterized by a focal point of pressure application on the forefoot and low pressure on the lateral region. Our data suggest that pressure clustering is a feasible means to identify inappropriate biomechanical plantar stress. PMID:27529421

    [Purpose] This study examined how the application of Low-Dye (LD) taping affected the pain and stability of patients with plantar fasciitis. [Subjects] The subjects were 30 patients with plantar fasciitis who were divided into two groups: a Low-Dye taping group (LTG, n=15) and a conservative treatment group (CTG, n=15). [Methods] The treatments were performed three times a week for six weeks in both groups. A visual analog scale (VAS) was used to evaluate the pain and stability of patients with plantar fasciitis, and the transfer area of the center of gravity (TAOCOG) was measured to evaluate stability using a BioRescue device. [Results] In the within-group comparison of the VAS, the LTG and CTG values significantly decreased. In the post-test between-group comparison, the VAS pain decreased more significantly in LTG than in CTG. In the within-group comparison of the TAOCOG, the LTG value significantly increased. In the post-test between-group comparison, the TAOCOG value increased more significantly than in LTG than in CTG. [Conclusion] Utilizing Low-Dye taping for patients with plantar fasciitis appears to be an effective intervention method for reducing pain and enhancing stability. PMID:26355306

    Background High forefoot plantar pressure is associated with plantar ulcers in people with diabetes and peripheral neuropathy. The purpose of this pilot study is to determine safety and efficacy of botulinum toxin A injected into the gastrocnemius-soleus muscles to reduce muscle strength and plantar pressure. Materials and Methods This double blind, randomized clinical trial studied 17 people with diabetes mellitus, peripheral neuropathy and forefoot plantar ulcer. Subjects were randomized into one of three groups receiving gastrocnemius-soleus muscle injections on the involved side with; 1) Saline (n=5, weight = 99 ± 21 kg), 2) 200 units of Botox® (n=7, weight = 101 ± 5 kg), or 3) 300 units of Botox® (n=5, weight=129 ± 22 kg). Botox® dose was converted to units/kg, the majority received between 1.9 and 2.4 units/kg (n=11) and one 3.2 units/kg. Plantarflexor peak torque and forefoot peak plantar pressure were quantified prior and two weeks post injection. Results There were no complications from the injections. Plantarflexor peak torque on the involved side increased in the placebo and 300 groups (3 ± 4 Nm and 6 ± 10 Nm respectively) and decreased −8 ± 11 Nm in the 200 group. There was no relationship between units/kg of Botox® for each subject and change in plantarflexor peak torque. Forefoot peak plantar pressure did not change in the placebo and 300 groups (0 ± 11 and 0 ± 5 N/cm2 respectively) and decreased −4 ± 16 N/cm2 (4%) for the 200 group. Conclusions There were no adverse events associated with the Botox® injections. This study was unable to determine the dose to consistently reduce plantarflexor strength and forefoot plantar pressure. Additional research is needed to investigate diabetes mellitus specific physiological changes and their impact of BoNT-A effectiveness in order to guide appropriate dosing. PMID:22735277

  18. The oscillatory behavior of the CoM facilitates mechanical energy balance between push-off and heel strike.

    Humans use equal push-off and heel strike work during the double support phase to minimize the mechanical work done on the center of mass (CoM) during the gait. Recently, a step-to-step transition was reported to occur over a period of time greater than that of the double support phase, which brings into question whether the energetic optimality is sensitive to the definition of the step-to-step transition. To answer this question, the ground reaction forces (GRFs) of seven normal human subjects walking at four different speeds (1.1-2.4 m/s) were measured, and the push-off and heel strike work for three differently defined step-to-step transitions were computed based on the force, work, and velocity. To examine the optimality of the work and the impulse data, a hybrid theoretical-empirical analysis is presented using a dynamic walking model that allows finite time for step-to-step transitions and incorporates the effects of gravity within this period. The changes in the work and impulse were examined parametrically across a range of speeds. The results showed that the push-off work on the CoM was well balanced by the heel strike work for all three definitions of the step-to-step transition. The impulse data were well matched by the optimal impulse predictions (R(2)>0.7) that minimized the mechanical work done on the CoM during the gait. The results suggest that the balance of push-off and heel strike energy is a consistent property arising from the overall gait dynamics, which implies an inherited oscillatory behavior of the CoM, possibly by spring-like leg mechanics.

    Abstract Fetal-type Minamata disease is caused by the exposure to high concentrations of methylmercury in the fetal period and shows cerebral palsy-like clinical features. Relief of spasticity is a major task of rehabilitation to improve their activities of daily living. Here we report the effect of long-term vibration therapy on bilateral lower-limb spasticity in 3 patients with fetal-type Minamata disease. We used a simple, inexpensive, and noninvasive approach with hand-held vibration massagers, which were applied to the plantar fascia at 90 Hz for 15 minutes. The effect was observed soon after the first treatment and resulted in better performance of the repetitive facilitation. Vibration therapy for 1 year improved Modified Ashworth Scale for the ankle flexors in 2 cases. The labored gait improved and gait speed increased in another case. Continued vibration therapy for another 1 year further improved Modified Ashworth Scale score and range of motion of ankle dorsiflexion in 1 case. This case showed the decreased amplitude of soleus H-reflex after the 15-minute vibration therapy, suggesting that α-motor neuron excitability was suppressed. Vibration therapy using a hand-held vibration massager may offer safe and effective treatment for lower-limb spasticity in patients with chronic neurological disorders. PMID:27082608

    The aim of this study was to compare the effectiveness of extracorporeal shock wave therapy (ESWT) and ultrasound therapy (US) for managing heel pain. Thirty-seven subjects received either: ESWT (once a week), US (three times a week), or CONTROL (no treatment) for 3 consecutive weeks and were followed-up for 3 more weeks. A visual analogue scale (VAS), the maximum tolerable duration for prolonged walking or standing, and the Mayo clinical scoring system (MCSS) were evaluated. Mixed models treating baseline measures as covariates were adopted for statistical analysis. By week 3, intensity of heel pain on palpation was reduced by 37% (VAS score from 7.5 to 4.6) in the ESWT group, 24% (from 5.3 to 4.2) in the US group, and increased by 3% (5.6-5.7) in the control group; this difference was significant after adjusting for baseline VAS scores ( p = 0.022). The improvements in the maximum tolerable duration of prolonged walking or standing was only significant in the ESWT group (157% increase, p = 0.043) but not the other two groups. Both active treatment groups maintained the treatment effect at the three-week follow-up. We conclude that ESWT is potentially more effective in reducing heel pain than ultrasound therapy but additional evidence is needed due to the various limitations of the study.

    Plantar fasciitis is a common condition, with most patients treated successfully with nonoperative management. Recalcitrant disease has been managed with surgical procedures that vary in design and associated morbidity. The present study sought to determine the intermediate-term results of percutaneous bipolar radiofrequency microtenotomy in recalcitrant plantar fasciitis. The patient medical records were reviewed, and data were gathered for all the patients who met the inclusion criteria. The foot function index and visual analog scale (VAS) pain scale questionnaires were mailed to the 111 patients. Of the 111 patients, 61 (55.0%) returned their questionnaires and were ultimately included in the present analysis. Of the 61 patients, 44 (72.1%) were female and 17 were (27.9%) male, with an average reported follow-up of 33.3 ± 8.6 (range 16.1 to 46.6) months. The median postoperative VAS score was 0.0 (range 0.0 to 10.0), and the median foot function index score was 3.1 (range 0.0 to 97.1). The patients were subdivided into success and failure groups according to their satisfaction. Of the 61 patients, 51 (83.6%) were satisfied and would recommend the procedure to a friend. The median VAS score in the success group was 0.0 (range 0.0 to 5.0), and the median VAS score in the failure group was 6.0 (range 0.0 to 10.0), a significant difference (p < .001). A significant difference was also seen in the foot function index score between the success (median 2.4, range 0.0 to 25.7) and failure (median 37.4, range 0.0 to 97.1) groups (p < .001). Bipolar radiofrequency microtenotomy appears to be a safe procedure that can provide outcomes equivalent to those with open surgery, with less morbidity, for recalcitrant plantar fasciitis.

    International Nuclear Information System (INIS)

    Objective: To assess the technical feasibility and efficacy of transdorsal-to-plantar (TDP) or transplantar-to-dorsal (TPD) intraluminal re-entry procedure following unsuccessful subintimal angioplasty for the treatment of arterial occlusion below the ankle. Methods: TDP or TPD retrograde intraluminal re-entry angioplasty was carried out in 8 diseased limbs of 8 diabetic patients (5 males and 3 females, aged 62∼81 years with a mean age of 75±8 years), who were accompanied with chronic below-the-ankle arterial occlusive disease, after the standard transtibial subintimal angioplasty had failed. Both before and after the procedure the clinical symptoms, dorsal or plantar arterial pulse volume scores and ankle-brachial indexes (ABI) were determined in all patients, the results were compared and statistically analysed. During the follow-up period, the degree of pain relief, the healing of the wound, the salvage of the diseased limb and the restenosis occurrence of the target vessels were evaluated. Results: Of the total 8 patients, TDP or TPD retrograde intraluminal re-entry angioplasty was successfully performed in 5(62.5%). After the treatment the foot pain was markedly relieved, the median pulse volume scores and ankle-brachial indexes were increased from 0.60±0.55 and 0.32±0.20 before the procedure to 2.40±0.55 and 0.75±0.12 after the procedure, respectively (P<0.01 for both). At the end of the follow-up lasting for twelve months, the visual analogue scale was apparently improved, the scores decreased from preoperative 7.40±1.14 to 2.20±1.48 (P=0.002). Of two cases with intractable skin ulcer, the skin lesion was completely healed in one and was significantly decreased in size in another. No amputation surgery was needed in all successfully treated patients. Magnetic resonance angiography revealed that one target vessel developed re-stenosis. Conclusion: TDP and TDP retrograde intraluminal re-entry techniques are clinically feasible and effective for the

    Full Text Available Varicella zoster virus (VZV, a human alphaherpesvirus, causes varicella and subsequently estab-lishes latency within sensory nerve ganglia. Later in life VZV can reactivate to cause herpes zoster. A reduced frequency of VZV-specific T cells is strongly associated with herpes zoster illustrating that these immune cells are central to control latency. Dendritic cells (DCs are required for the generation of VZV-specific T cells. However, DCs can also be infected in vitro and in vivo allowing VZV to evade the antiviral immune response. Thus, DCs represent the immune systems’ Achilles heel. Uniquely among the human herpesviruses, VZV infects both DCs and T cells, and exploits both as Trojan horses. During primary infection VZV-infected DCs traffic to the draining lymph nodes and tonsils, where the virus is transferred to T cells. VZV-infected T cells subsequently spread infection throughout the body to give the typical varicella skin rash. The delicate interplay between VZV and DCs and its consequences for viral immune evasion and viral dissemination will be discussed in this article.

    Research Funded by the Lexington Clinic Foundation for Research and Education. Posterior heel pain (PHP) presents a difficult clinical challenge. The causes of PHP include Haglund syndrome (pump bump deformity), Achilles tendinitis, and Sever's disease (retrocalcaneal bursitis, traction apophysitis). The purposes of this study were to 1) describe a new orthotic device used in the treatment of PHP and 2) evaluate the effectiveness of this device. The orthotic device consisted of a neoprene sleeve holding 1/4 inch PPT foam rubber horseshoe (Sports Supports, Inc., Dallas, TX). The horseshoe was placed directly over the injury to protect and relieve pressure or was inverted and used as a counterforce brace to reduce the tensile stress to the Achilles tendon. Eight patients (6 children, 2 adults) were evaluated at the time of application and after 1 month of use. Three criteria were considered: 1) subjective pain scale, 2) active goniometric measurements, and 3) toe raise test. The statistical analysis indicated a significant improvement in pain during activity from initial to follow-up and in pain after activity from initial to follow-up. All patients demonstrated improved strength and flexibility. It was concluded that this device may be an effective adjunct to the treatment of PHP. J Orthop Sports Phys Ther 1990;11(9):410-413.

    Mixtures of oxalic acid with nitric acid have been shown to be superior to oxalic acid alone for the dissolution of iron-rich High Level Waste sludge heels. Optimized conditions resulting in minimal oxalate usage and stoichiometric iron dissolution (based on added oxalate ion) have been determined for hematite (a primary sludge iron phase) in oxalic/nitric acid mixtures. The acid mixtures performed better than expected based on the solubility of hematite in the individual acids through a synergistic effect in which the preferred 1:1 Fe:oxalate complex is formed. This allows for the minimization of oxalate additions to the waste stream. Carbon steel corrosion rates were measured in oxalic/nitric acid mixtures to evaluate the impacts of chemical cleaning with these solutions on waste tank integrity. Manageable corrosion rates were observed in the concentration ranges of interest for an acid contact timescale of 1 month. Kinetics tests involving hematite and gibbsite (a primary sludge aluminum phase) have confirmed that {ge}90% solids dissolution occurs within 3 weeks. Based on these results, the chemical cleaning conditions recommended to promote minimal oxalate usage and manageable corrosion include: 0.5 wt. % oxalic acid/0.175 M nitric acid mixture, 50 C, 2-3 week contact time with agitation.

    Free flaps are still the gold standard for large defects of the lower limb, but propeller perforator flaps have become a simpler and faster alternative to free flaps because of some advantages such as reliable vascular pedicle, wide mobilization and rotation, great freedom in design, low donor site morbidity, and easy harvest with no requirement for anastomosis. But when the vessels show insufficient findings in preoperative evaluation using a Doppler probe or the vessel is injured, the surgeon should avoid performing free flap surgery to prevent flap failure and should select a propeller perforator flap as an alternative method on the condition that more than one perforator is intact. In this study, we report reconstruction of soft tissue defects of the heel with a pedicled propeller flap in postfasciotomy and popliteal artery revascularization state by making an incision on the central portion above the Achilles tendon, which can be covered by the posterior tibial artery perforator or the peroneal artery perforator based flaps. In conclusion, we showed that although the popliteal artery was injured, the soft tissue defect can be reconstructed using a perforator propeller flap if intact distal flow in the anastomosis site was confirmed.

    2007-01-01

    The present paper introduces an original biofeedback system for improving human balance control, whose underlying principle consists in providing additional sensory information related to foot sole pressure distribution to the user through a tongue-placed tactile output device. To assess the effect of this biofeedback system on postural control during quiet standing, ten young healthy adults were asked to stand as immobile as possible with their eyes closed in two conditions of No-biofeedback and Biofeedback. Centre of foot pressure (CoP) displacements were recorded using a force platform. Results showed reduced CoP displacements in the Biofeedback relative to the No-biofeedback condition. The present findings evidenced the ability of the central nervous system to efficiently integrate an artificial plantar-based, tongue-placed tactile biofeedback for controlling control posture during quiet standing.

    The management of children who present to the ED with plantar puncture wounds is dependent upon the nature of the injury, the examination of the puncture site, and the potential risk of a retained foreign body. Not all patients will require wound enlargement and a search for a retained foreign body. Close follow-up of all children who are being treated as outpatients is of vital importance in detecting an early development of an infectious complication. Pseudomonas osteomyelitis should be suspected in all patients who present with foot pain, swelling, and a decreased ability to bear weight after sustaining a nail puncture through a sneaker. The current consensus favors open surgical débridement followed by a course of intravenous antibiotics. The exact duration of the postoperative antibiotic course is still being debated. PMID:1603689

    The effects of the Youngswick osteotomy on plantar peak pressure distribution in the forefoot are presented for 17 patients (23 feet) with mild-to-moderate hallux limitus deformity and 23 control subjects (23 feet). During 2 years of follow-up, the operation produced a significant increase in the range of dorsiflexion of the first metatarsophalangeal joint in these patients, reaching near-normal values. Preoperative and postoperative measurements, using a pressure-distribution measurement system, show that peak pressure beneath the hallux and the first metatarsal head remained unchanged. However, peak pressure was significantly increased beneath the second metatarsal head and decreased beneath the fifth metatarsal head. These findings suggest that the foot functioned in a less inverted manner postoperatively. Compared with normal feet, hallux limitus feet demonstrated significantly higher peak pressure beneath the fourth metatarsal head preoperatively and postoperatively. PMID:14729987

Ankle dorsiflexion passive ROM increased in the stretched limb after the SS (pre-test: 21 ± 4° and post-test: 26.5 ± 5°, p < 0.001. Post-stretching decreases were observed with peak force (p = 0.029, IEMG (P<0.001, and IEMGpre-activation (p = 0.015 in the stretched limb; as well as impulse (p = 0.03, and jump height (p = 0.032 in the non-stretched limb. In conclusion, SS effectively increased passive ankle ROM of the stretched limb, and transiently (less than 10 minutes decreased muscle peak force and pre-activation. The decrease of jump height and impulse for the non-stretched limb suggests a SS-induced central nervous system inhibitory effect.

Methods 32 fixed adult lower limb specimens were used in the study. The ADMN was dissected for observing it's origin, course, branches and distribution. Results For cases of 81.25%, ADMN originated from the lateral plantar nerve, which consisted of 19 trunks (59.38%) located in the postcrosuperior quadrant. The vertical depth of the origin site to the reference line was (10.81±0.96)mm and (10.24±1.10) mm at left and right sides respectively. ADMN firstly issued 1-3 periosteum branches, which arrived the periosteum of medial process of calcaneal tuberosity. The horizontal distances from the site of medial process of calcaneal tuberosity to the left or right tuberosities were (19.95*1.82) mm and (20.89 ±2.48)mm, seperately. Conclusions ADMN is probably stamped when it goes through the abductor hallucis, the medial head of quadratus plantae and the medial process of calcaneal tuberosity. The stamp or lesion of ADMN (especially periosteum branch) is probably

    The study was performed to investigate a new bone-ligament-bone autograft from the plantar plate of the toes. The anatomic properties of the plantar ligaments and the technical feasibility to harvest a bone-ligament-bone graft were examined to evaluate the potential use of this graft for a suitable reconstruction of the scapholunate (SL) interosseous ligament. The plantar plate of the metatarsophalangeal joints of the second to fifth toe and the proximal interphalangeal joints of the second to fourth toe were examined in 20 cadaver feet (15 fresh and 5 embalmed cadavers) and measurements such as length, thickness, and width were taken. The average length of the plantar ligaments of the proximal interphalangeal joint was 0.63 cm (D3) and 0.62 cm (D4). The length of the plantar plates of the proximal interphalangeal joint of the third and fourth toe was found to be similar to that of the SL ligament. In addition to the measurements, a bone-ligament-bone autograft of the plantar plates of the metatarsophalangeal joint was designed as an SL-ligament substitute and successfully transplanted into cadaveric wrists. This new autograft is intercalated between the scaphoid and lunate and, contrary to all previous methods, not simply superimposed upon them. Length of the plantar plates was considered by the authors as the main criteria for selection of the new bone-ligament-bone graft. The plantar plate of the proximal interphalangeal joint of the third and fourth toe showed a similar length compared with the SL ligament. Therefore, it can be concluded from the data that this bone-ligament-bone graft can be a suitable replacement for the SL ligament. PMID:18812722

  19. Chronic recurrent multifocal osteomyelitis: how to suggest this diagnosis?

    International Nuclear Information System (INIS)

    Chronic recurrent multifocal osteomyelitis is a rare disorder that affects children and teenagers. Clinically, it is characterized by insidious onset of local swelling and pain in several metaphyses. A symmetric, recurrent and multifocal pattern is usual. Spinal involvement is possible. Inconstant association with a cutaneous affection (palmo-plantar pustulosis, acne fulminans, psoriasis), or less frequently with an inflammatory chronic gut disorder is described. Pathogenesis usually recognized is an enthesopathy. Enthesitis may progress to the osseous part of the enthese and produce an aseptic chronic osteomyelitis. Biopsy specimen with culture is certainly necessary to rule out bacterial osteomyelitis and bone tumor. It is particularly true when the bone lesion is isolated. Disease course is benign and self-limited. The clinical course is characterized by recurrences and remissions occurring for 6 to 10 years. Treatment based on non steroid anti-inflammatory drugs is usually effective. (authors)

  3. Kinaesthetic ipsilateral and crossed extensor plantar response: A new way to elicit upgoing toe sign (Babinski response?

    Directory of Open Access Journals (Sweden)

    Abraham Kuruvilla

    2011-01-01

    Full Text Available We describe a phenomenon of "kinaesthetic extensor plantar response" in advanced pyramidal dysfunction, an interesting observation noted in a patient with dorsal myelopathy. A 44-year-old woman presented with one-year history of gradually progressive weakness and stiffness of both lower limbs along with urge incontinence of urine. Examination showed spontaneous elicitation of extensor plantar response while assessing the tone by rolling method as well as on noxious stimulation of the thigh. Magnetic resonance imaging (MRI of the dorsal spine and digital subtraction angiography showed the presence of spinal dural arteriovenous fistula causing myelopathy. This case exemplifies the fact that in advanced pyramidal dysfunction, not only the receptive field of Babinski reflex may extend to the leg or thigh, but may also integrate with other modalities of stimulation, such as the rolling movement. The possible underlying pathophysiology of such a phenomenon is discussed.

    The purpose of the present study was to determine the effects of a plantar pressure-based, tongue-placed tactile biofeedback on postural control mechanisms during quiet standing. To this aim, sixteen young healthy adults were asked to stand as immobile as possible with their eyes closed in two conditions of No-biofeedback and Biofeedback. Centre of foot pressure (CoP) displacements, recorded using a force platform, were used to compute the horizontal displacements of the vertical projection the centre of gravity (CoGh) and those of the difference between the CoP and the vertical projection of the CoG (CoP-CoGv). Altogether, the present findings suggest that the main way the plantar pressure-based, tongue-placed tactile biofeedback improves postural control during quiet standing is via both a reduction of the correction thresholds and an increased efficiency of the corrective mechanism involving the CoGh displacements.

    Full Text Available Introduction: The treatment of patients with plantar warts continues to be a frustrating matter for both primary care physicians and dermatologists. There are new trends towards the use of immunotherapy in treatment of warts, as the immune system seems to play an important role in the control of warts infection. Aim: Assessing the efficacy of intralesional injection of MMR vaccine (measles, mumps, rubella in the treatment of plantar warts. Patients: One hundred patients complaining of plantar warts were included in this study. Methods: The patients were divided into two groups: Group 1: This group included 50 patients subjected to intralesional injection of measles, mumps, rubella vaccine (MMR. Group 2: This group included 50 patients as a control group and subjected to intralesional injection of 0.3 ml saline. Only single wart was injected. Injections were done at 3-weeks interval until complete clearance or for a maximum of 3 treatments. Follow up of patients was done every month for six months for clinical assessment of results and to show any recurrence. Results: Regarding the response of the target wart, MMR- treated group showed significantly higher rate of complete clearance compared with the control group (82% versus 0% respectively. The rate of partial response was 6% versus 30%, and the rate of no response was 12% versus 70%, respectively. Regarding the response of untreated distant warts, MMR-treated group showed 86.9% complete and 13.1% partial clearance of the warts whereas the control group showed 100% no response. This strongly indicates the development of a widespread HPV-targeted immunity as a response of antigen injection and represents a major advantage of the intra lesional immunotherapy. Conclusions: We found that treatment of plantar warts by MMR vaccine is effective, with good cure rates and excellent safety profile..

  7. A lumped-parameter model to investigate the effect of plantar pressure on arterial blood flow in a diabetic foot.

    2007-08-01

    This paper presents a lumped-parameter model for the big-toe region that investigates the effect of plantar pressure on the diameter of the blood vessels, specifically the arteries, in the presence of arterial and/or tissue changes. The model developed in this paper uses a multi-domain energy system approach to develop the lumped-parameter differential equations. Blood flow is modelled as fluidic flow through compliant pipes that have inertia, stiffness, and damping. The tissue material is treated as a soft compliant material that transmits the external force to the blood vessels. Conclusions have been drawn to show the effect of plantar pressure, tissue damage, and their combination on the diameter of the blood vessels. The principles used here can be used to model the entire foot and the model used to investigate the effect of plantar pressure, tissue damage, and arterial changes on different parts of the foot. The work presented here may also have applications in other vascular diseases. PMID:17937206

    Among children, postural modifications due to backpack carriage have direct consequences on how forces are exchanged between body and ground and thus on plantar pressure distribution. However, it is unknown whether such alterations are influenced by the foot structure and functionality typical of obesity. In this study, we tested 65 overweight/obese primary schoolchildren using a pressure platform while walking with and without the backpack. Contact areas, arch index, peak and mean plantar pressures in the forefoot, midfoot and rearfoot were compared with those from an additional 65 age- and gender-matched group of normal-weight children. Backpack carriage modified pressure distribution similarly in both groups, with the exception of mean midfoot pressure, which increased significantly among normal-weight children but not in the overweight/obese group. Notably, the pressure values associated with mass excess and backpack carriage still raise some concerns regarding potential long-term adverse consequences on foot structure and functionality of overweight/obese children. Practitioner summary: Backpack carriage by overweight/obese schoolchildren altered plantar pressures similar to what was observed in their normal-weight peers. Yet, high pressures were found among the overweight/obese children. This raises concerns regarding potential long-term adverse consequences on foot structure and functionality, and supports establishing more specific limits for the carried load. PMID:26226045

  9. Solid Phase Characterization Of Heel Samples From Tank 241-C-110

    International Nuclear Information System (INIS)

    During sluicing operations of tank 241-C-110, a significant amount of solids were unable to be retrieved. These solids (often referred to as the tank 'heel') were sampled in 2010 and chemically and mineralogically analyzed in the 222-S Laboratory. Additionally, dissolution tests were performed to identify the amount of undissolvable material after using multiple water contacts. This report covers the solid phase characterization of six samples from these tests using scanning electron microscopy, polarized light microscopy, and X-ray diffraction. The chemical analyses, particle size distribution analysis, and dissolution test results are reported separately. Two of the samples were from composites created from as-received material - Composite A and Composite B. The main phase in these samples was sodium-fluoride-phosphate hydrate (natrophosphate) - in the X-ray diffraction spectra, this phase was the only phase identifiable. Polarized light microscopy showed the presence of minor amounts of gibbsite and other phases. These phases were identified by scanning electron microscopy - energy dispersive X-ray spectroscopy as sodium aluminosilicates, sodium diuranate, and sodium strontium phosphate hydrate (nastrophite) crystals. The natrophosphate crystals in the scanning electron microscopy analysis showed a variety of erosive and dissolution features from perfectly shaped octahedral to well-rounded appearance. Two samples were from water-washed Composites A and B, with no change in mineralogy compared to the as-received samples. This is not surprising, since the water wash had only a short period of water contact with the material as opposed to the water dissolution tests. The last two samples were residual solids from the water dissolution tests. These tests included multiple additions of water at 15 C and 45 C. The samples were sieved to separate a coarser fraction of > 710 μm and a finer fraction of < 710 μm. These two fractions were analyzed separately. The coarser

    Objective: To calibrate a Quantitative Ultrasonography (QUS) system against densitometry by defining the sensitivity and specificity of the method, and to propose a series of QUS interpretation thresholds to classify the individual risk with regards to the risk of developing osteoporosis in later life. Methods: Subjects were recruited in New York City over a 1-year period. Women with amenorrhea for at least 12 months were defined as postmenopausal, and all other women as premenopausal. Bone mineral density (BMD) was measured with a dual energy X-ray absorptiometer (DXA) and QUS performed with the calcaneus of broadband ultrasound attenuation (BUA) and speed of sound (SOS) using the Lunar Achilles system. Statistical analysis was performed using SPSS software Version 10.0. Results: Two hundred twenty-eight premenopausal and menopausal women were recruited. Most of the participants were Hispanic, Caucasian and African-American in this study. All the subjects had DXA and QUS examined and T-score was got from both. The statistical results showed that the T-score of QUS has a significant relationship with that of DXA(spine: r=0.557, P<0.0001;femur: r=0.611,P<0.0001). Both QUS and DXA T-score has a significant and negative relationship with age (QUS: r=-0.241, P<0.0001; Spine: r=-0.277, P<0.0001; femur: -0.296, P<0.0001). When T-score of heel ultrasound -1.5 was set as the interpretation threshold, the osteoporosis patients with T-score of DXA-femur scan (100%) and DXA-spine (77.10%) less than -2.5 were detected. As well, the specificities of T-score -1.5 of QUS for DXA-femur and DXA-spine were 67.5% and 72.8%, respectively. In addition, if we set -1.0 of T-score of QUS as the cutoff, 74.80% and 79.60% of the osteopenia based on DXA of spine and femur were identified. The specificities were 59.4% and 57.7%. Conclusions: QUS of the calcaneus may be an effective method for providing risk stratification for osteoporosis, and for the closely associated future risk

    Full Text Available BACKGROUND: Since 2006, the Italian National Institute of Health (ISS has been conducting independent scientific activities to standardize the technical assessment of plantar pressure measurement devices (PMDs. MATERIAL AND METHODS: On the basis of the ISS results, in 2010 the Pedobarographic Group of the International Foot and Ankle Biomechanics community (i-FAB-PG promoted a consensus activity about the main technical requirements for the appropriate use of PMDs. The activity relied on a moodlebased on-line forum, documents exchange, discussions, reviews, meetings and a final survey. RESULTS: The participation of clinical and technical researchers, users, and manufacturers, contributed to the delivery of the hereby reported recommendations which specifically regard Medical PMDs in the form of platforms. CONCLUSIONS: The i-FAB-PG community reached overall agreement on the recommendations, with a few minor objections which are reported and commented in the document. RELEVANCE: The present document, the highest result achievable within a small scientific community, will hopefully represent the starting point of the wider process of establishing official international guidelines or standards, within scientific communities and standardization organizations.

  13. Quantitative Estimation of Temperature Variations in Plantar Angiosomes: A Study Case for Diabetic Foot

    Directory of Open Access Journals (Sweden)

    H. Peregrina-Barreto

    2014-01-01

    Full Text Available Thermography is a useful tool since it provides information that may help in the diagnostic of several diseases in a noninvasive and fast way. Particularly, thermography has been applied in the study of the diabetic foot. However, most of these studies report only qualitative information making it difficult to measure significant parameters such as temperature variations. These variations are important in the analysis of the diabetic foot since they could bring knowledge, for instance, regarding ulceration risks. The early detection of ulceration risks is considered an important research topic in the medicine field, as its objective is to avoid major complications that might lead to a limb amputation. The absence of symptoms in the early phase of the ulceration is conceived as the main disadvantage to provide an opportune diagnostic in subjects with neuropathy. Since the relation between temperature and ulceration risks is well established in the literature, a methodology that obtains quantitative temperature differences in the plantar area of the diabetic foot to detect ulceration risks is proposed in this work. Such methodology is based on the angiosome concept and image processing.

    A new computational model, based on the thermodynamically constrained averaging theory, has been recently proposed to predict tumor initiation and proliferation. A similar mathematical approach is proposed here as an aid in diabetic ulcer prevention. The common aspects at the continuum level are the macroscopic balance equations governing the flow of the fluid phase, diffusion of chemical species, tissue mechanics, and some of the constitutive equations. The soft plantar tissue is modeled as a two-phase system: a solid phase consisting of the tissue cells and their extracellular matrix, and a fluid one (interstitial fluid and dissolved chemical species). The solid phase may become necrotic depending on the stress level and on the oxygen availability in the tissue. Actually, in diabetic patients, peripheral vascular disease impacts tissue necrosis; this is considered in the model via the introduction of an effective diffusion coefficient that governs transport of nutrients within the microvasculature. The governing equations of the mathematical model are discretized in space by the finite element method and in time domain using the θ-Wilson Method. While the full mathematical model is developed in this paper, the example is limited to the simulation of several gait cycles of a healthy foot. PMID:24841993

    Disagreements exist in the literature regarding the manner in which weight should be dynamically shared during the golf swing, both within-feet and between the back- and target-foot, to generate maximal clubhead speed. The purpose of this study was to determine whether preferential foot-loading locations underlie weight sharing by examining the correlation between clubhead speed and maximum plantar pressure (PP) distributions. Thirty-two amateur golfers with handicap indexes ranging from 2.7 to 25 performed 10 driver swings on artificial turf following a warm-up. PP distributions were recorded at 100 Hz, and clubhead speed was recorded using a ball-tracking Doppler radar system. Maximum PPs were extracted from a 2-s window approximately centred on ball contact and were regressed against clubhead speed. Significance was assessed over the entire foot surface using statistical parametric mapping (SPM), a spatially continuous technique. SPM revealed, at relatively high anatomical resolution, significant positive correlations between clubhead speed and PPs in the lateral target-foot (P < 0.05). This suggests that not only weight transfer but also weight-transfer location may be an important determinant of clubhead speed in amateur golfers. PMID:25010946

    Full Text Available This paper investigates the measurement of fat-free mass (FFM by bioimpedance using foot-to-foot impedancemeters (FFI with plantar electrodes measuring the foot-to-foot resistance R34 and hand-to-foot medical impedancemeters. FFM measurements were compared with corresponding data using Dual X-ray absorptiometry (DXA. Equations giving FFM were established using linear multiple regression on DXA data in a first group of 170 subjects. For validation, these equations were used on a second group of 86 subjects, and FFM were compared with DXA data; no significant difference was observed. The same protocol was repeated, but using electrodes on the right hand and foot in standing position to measure the hand to-foot resistance R13. Mean differences with DXA were higher for R13 than for R34. Effect of electrode size and feet position on resistance was also investigated. R34 decreased when electrode area increased or if feet were moved forward. It decreased if feet were moved backward. A proper configuration of contact electrodes can improve measurement accuracy and reproducibility of FFI.

    Full Text Available In order to conduct the gait recognition system, a wireless in-shoe wearable plantar pressure acquisition system based on ATmega16 and 8 FSR sensors was applied to data acquisition for the gaits which consist of standing, walking, jumping and going upstairs. And four volunteers (2 females and 2 males were invited in this research to collect the pressure information. MATLAB and LIBSVM were applied to conduct all algorithms proposed by this study. Genetic Algorithm (GA was used to set the best tuning (penalty parameter  and the best  (gamma of Gauss radial basis kernel (RBF for C-support vector classification (C-SVC model and the GA-based C-SVC was obtained. A dataset named ‘train-data’, containing 800 sets of pressure data was used to train the GA-based C-SVC as the algorithm of gait recognition. Finally a testing dataset containing 400 sets of pressure data was applied to test the algorithm of gait recognition called GA-based C-SVC. The accuracy of this GA-based C-SVC was 98% for standing, 91% for walking, 82% for going-upstairs and 97% for jumping. In generally speaking, a better GA-based C-SVC was obtained in this research.

    Occlusion calibrations and gating techniques have been recently applied by our laboratory for continuous and absolute diffuse optical measurements of forearm muscle hemodynamics during handgrip exercises. The translation of these techniques from the forearm to the lower limb is the goal of this study as various diseases preferentially affect muscles in the lower extremity. This study adapted a hybrid near-infrared spectroscopy and diffuse correlation spectroscopy system with a gating algorithm to continuously quantify hemodynamic responses of medial gastrocnemius during plantar flexion exercises in 10 healthy subjects. The outcomes from optical measurement include oxy-, deoxy-, and total hemoglobin concentrations, blood oxygen saturation, and relative changes in blood flow (rBF) and oxygen consumption rate (rV˙O2). We calibrated rBF and rV˙O2 profiles with absolute baseline values of BF and V˙O2 obtained by venous and arterial occlusions, respectively. Results from this investigation were comparable to values from similar studies. Additionally, significant correlation was observed between resting local muscle BF measured by the optical technique and whole limb BF measured concurrently by a strain gauge venous plethysmography. The extensive hemodynamic and metabolic profiles during exercise will allow for future comparison studies to investigate the diagnostic value of hybrid technologies in muscles affected by disease.

    The creation of a Plantar Load Index (PLI) is proposed, with a view to studying the plantar surface of the foot from a morphofunctional standpoint. This Index would provide information on the centesimal relationship between the surface load values and the total projective values of the foot, expressed in cm2. The measurements in question are homogeneous in nature and may, therefore, be easily related to one another. To obtain these values, the two surfaces are visualized, photographed together in a single photogram and analyzed by means of the computerized visual system (Zeiss Videoplan). Visualization is obtained by means of a thermochromatic variation plate which is placed on the stand of a reflexion podoscope and which is sensitive to the heat of the plantar skin and the suitably emitted infra-red rays. The heat of the skin in contact with the plate shows the load surface. The intra-red rays suitably emitted from above onto the plate and onto the back of the foot produce the general chromatic variation of the plate, also showing the perimetrical outline of the foot. The picture to be photographed will, then, be as follows: a continuous black edge formed from the outside by the colouring of the plate produced by the infra-red rays (the perimeter of the foot); more black, extending inwards, in varying degrees, when the skin is not touching the plate (the archer and furrows in the skin); coloured areas inside of the perimeter, showing the load surface.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6626330

    Full Text Available Background. Currently, free flaps and pedicled flaps are the first treatment choices for large heel ulcer reconstruction. However, flap reconstruction of heel ulcerations cannot be performed in all diabetics especially with concurrent severe peripheral vascular disease because of higher flap failure rate. In recent years, the use of acellular dermal matrix (ADM has emerged as an alternative treatment option for extremity ulcers. Methods. We present 13 diabetic patients with a large heel ulceration exposing the calcaneus, who were not eligible for flap surgery due to the presence of only one patent artery of trifurcation. These cases were treated with the vacuum assisted sandwich dermal matrix (VASDEM method. Results. None of the patients required amputation. Skin grafting was successful in ten patients. Although partial losses were observed in three patients, they were healed spontaneously without surgical interventions. During the follow-up period none of the patients developed ulceration on the treatment area. All patients maintained their preoperative ambulatory ability. Conclusion. VASDEM is a novel method offering opportunity for treatment before proceeding to amputation in diabetic heel ulceration exposing the calcaneus which is not suitable for flap surgery. It also has the potential to close wounds of all sizes independent of the vessel status and wound size in selected diabetic patients.

    In this paper, we propose an advanced pedestrian dead-reckoning (PDR) algorithm that considers the heel-strike and toe-off phases. Generally, PDR systems that use a foot-mounted inertial measurement unit are based on an inertial navigation system with an extended Kalman filter (EKF). To reduce the influence of the bias and white noises in the gyroscope and accelerometer signals, a zero-velocity update is often adopted at the stance phase. However, transient and large acceleration, which cannot be measured by the accelerometer used in pedestrian navigation, occur momentarily in the heel-strike phase. The velocity information from integration of the acceleration is not reliable because the acceleration is not measured in the heel-strike phase. Therefore, the designed EKF does not correctly reflect the actual environment, because conventional algorithms do not take the non-measurable acceleration into consideration. In order to reflect the actual environment, we propose a PDR system that considers the non-measurable acceleration from the heel-strike impact. To improve the PDR system’s performance, the proposed algorithm uses a new velocity measurement obtained using the constraint between the surface and the foot during the toe-off phase. The experimental results show improved filter performance after comparison of the proposed algorithm and a conventional algorithm.

    To identify the variety of second and third intermetatarsal space (IS) lesions that may coexist with and without adjacent metatarsophalangeal joint (MTP) plantar plate (PP) tears. One hundred forefoot MRIs in 96 patients with metatarsalgia obtained between 30 September 2011 and 21 July 2012 using 1.5- or 3-T MRI were retrospectively reviewed in consensus by two MSK radiologists and one podiatrist (DPM). MRI was evaluated for second and third MTP PP tear and the presence/nature of second and third IS lesions. Second and third IS neuromas were measured in transverse (trans) dimension. A total of 40 PP tears were identified: 36 at the second and 4 at the third MTP. Second MTP PP tear was identified in 33 % of females and 40.5 % of males. In the 63 female feet there were 21 second MTP PP tears, all of which also had second IS lesions: pericapsular fibrosis (16), bursitis (4), and ganglion (1). In the 37 male feet there were 15 second MTP PP tears, 14 of which had second IS lesions: pericapsular fibrosis (8), bursitis (5), and ganglion (1). There was no definite second IS neuroma adjacent to any second MTP PP tear. In females without PP tear, there were 24 second (3 mm trans average) and 43 third IS neuromas (4.1 mm trans average). In males without PP tear, there were 9 second (3.4 mm trans average) and 16 third IS neuromas (4.1 mm trans average). MTP PP tears occurred in 40 % of our cases, 90 % of which occurred at the second MTP. Almost all coexisted with non-neuromatous second IS lesions. (orig.)

    Purpose Palmar-plantar erythrodysethesia (PPE) is a common chemotherapy and anti-VEGF multi-kinase inhibitor class-related toxicity that often results in debilitating skin changes and often limits the use of active anti-cancer regimens. Mechanistic and anecdotal clinical evidence suggested that topical application of sildenafil cream may help reduce the severity of PPE. Therefore, we conducted a randomized, double-blind, placebo-controlled pilot study to evaluate the feasibility, safety and efficacy of topical sildenafil cream for the treatment of PPE. Methods Eligible subjects were required to have grade 1–3 PPE associated with either capecitabine or sunitinib. Subjects were randomized to receive 1% topical sildenafil cream to the left extremities or right extremities and placebo cream on the opposite extremity. 0.5 mL of cream was applied to each affected hand/foot two times per day. The primary endpoint was improvement in PPE grading at any point on study. Clinical assessments were evaluated by NCI-CTC 4.0 grading and patient self-reported pain. Results Ten subjects were enrolled; 9 were evaluable for safety and efficacy. Five of nine subjects reported some improvement in foot pain and 3 of 8 subjects for hand pain improvement. One of these subjects noted specific improvement in tactile function. No treatment-related toxicities were observed. Conclusions In this limited, single center study, topical cream containing 1% sildenafil is feasible to administer, is well-tolerated, and may mitigate PPE-related symptoms due to anti-cancer therapeutic agents. Further validation is necessary. PMID:25341548

    Full Text Available Abstract Background Low-dye (LD taping is commonly used to reduce rearfoot pronation. No studies have previously investigated the effectiveness of LD taping using both plantar pressure distribution (F-Scan and 3-D (CODA analysis of rearfoot motion. Methods 20 healthy subjects with a navicular drop test exceeding 10 mm participated in the study. T tests were used to determine whether significant (p Results LD taping resulted in statistically significant increases in peak plantar pressure in the lateral midfoot (p = 0.000, along with significant decreases in pressure in the medial forefoot (p = 0.014, and the medial (p = 0.000 and lateral hindfoot (p = 0.007. No significant changes occurred in the medial midfoot (p = 0.794 or lateral forefoot (p = 0.654. When assessed using motion analysis, taping resulted in a statistically significant decrease in rearfoot pronation (p = 0.006, supination (p = 0.025 and total rearfoot range of motion (p = 0.000. The mean rearfoot position during stance was not significantly different however (p = 0.188. Conclusion LD taping is associated with alterations in peak plantar pressure in the midfoot and forefoot that indicate reduced pronation with LD taping. However, LD taping appears to reduce both pronation and supination in the rearfoot, rather than simply reducing pronation, when assessed using 3D motion analysis. Therefore, it would appear that LD taping does indeed reduce pronation, by restricting rearfoot motion in general, rather than pronation specifically. The degree of change observed with LD taping was however very small, and further research is needed to clarify the clinical significance of these initial findings.

  10. Prospective Randomized Comparison of the Effectiveness of Radiation Therapy and Local Steroid Injection for the Treatment of Plantar Fasciitis

    Purpose: The purpose of this study was to conduct a randomized trial of radiation therapy for plantar fasciitis and to compare radiation therapy with local steroid injections. Methods and Materials: Between March 2013 and April 2014, 128 patients with plantar fasciitis were randomized to receive radiation therapy (total dose of 6.0 Gy applied in 6 fractions of 1.0 Gy three times a week) or local corticosteroid injections a 1 ml injection of 40 mg methylprednisolone and 0.5 ml 1% lidocaine under the guidance of palpation. The results were measured using a visual analog scale, a modified von Pannewitz scale, and a 5-level function score. The fundamental phase of the study was 3 months, with a follow-up period of up to 6 months. Results: The median follow-up period for all patients was 12.5 months (range, 6.5-18.6 months). For the radiation therapy patients, the median follow-up period was 13 months (range, 6.5-18.5 months), whereas in the palpation-guided (PG) steroid injection arm, it was 12.1 months (range, 6.5-18.6 months). After 3 months, results in the radiation therapy arm were significantly superior to those in the PG steroid injection arm (visual analog scale, P<.001; modified von Pannewitz scale, P<.001; 5-level function score, P<.001). Requirements for a second treatment did not significantly differ between the 2 groups, but the time interval for the second treatment was significantly shorter in the PG steroid injection group (P=.045). Conclusion: This study confirms the superior analgesic effect of radiation therapy compared to mean PG steroid injection on plantar fasciitis for at least 6 months after treatment

    To compare the effectiveness of the two therapeutic approaches, ultrasound and low level laser (LLLT) used in 181 patients suffering from calcar calcanei-plantar fasciitis. The effectiveness of the treatment was determined according to the evaluation of the patient using certain criteria described in the table. The complete disappearance of pain was seen in 50% of 60 patients treated with US and partial improvement in 16.6% and 69 patients were treated with LLLT from which 67% described complete pain relief, and 20% partial improvement. The results show that the LLLT is a good therapeutic approach in the treatment of pain in patients suffering from calcar calcanei-plantar fasciitis. The treatment with laser was significantly more successful then the ultrasound therapy, which is currently the most common therapy used for plantar fasciitis.

These systems present errors and no compensation information is presented by the manufacturer, leading to uncertainty in the measurements. Ten healthy subjects, 5 females and 5 males, were recruited. Lateral load distribution, antero-posterior load distribution, average pressure, contact area, and force were recorded. The aims of this study were to assess repeatability of the EcoWalk system and identify the range of pressure values observed in the normal foot. The coefficient of repeatability was less than 4% for all parameters considered.

    Full Text Available Background and Aim: Results of previous studies have been conflicting on the efficacy of extracorporeal shock wave therapy (ESWT in the treatment of plantar fasciitis. We evaluated the effects of ESWT on plantar fasciitis in terms of ultrasonographic and subjective evaluations. Materials and Methods: In this randomized placebo-controlled trial, patients with plantar fasciitis were assigned to receive ESWT (4000 shock waves/session of 0.2 mJ/mm 2 in 3 sessions at weekly intervals or sham therapy (n = 20 in each group. Outcomes were documented by the ultrasonographic appearance of the aponeurosis and by patients′ pain scores, performed at baseline and 12 weeks after completion of the therapy. Results : The two groups were similar in baseline characteristics. Over the study period, plantar fascia thickness significantly reduced in the ESWT group (4.1 ± 1.3 to 3.6 ± 1.2 mm, P < 0.001, but slightly increased in the sham group (4.1 ± 0.8 to 4.5 ± 0.9 mm, P = 0.03. Both groups showed significant pain improvement over the course of the study (P < 0.001, though pain scores were significantly more reduced in the ESWT than the sham group (-4.2 ± 2.9 vs. -2.7 ± 1.8, P = 0.049. Conclusions: Extracorporeal shock wave therapy contributes to healing and pain reduction in plantar fasciitis and ultrasound imaging is able to depict the morphologic changes related to plantar fasciitis as a result of this therapy.

  18. Low-pressure, single-point grout injection for tank heel sludge mixing and in-situ immobilization

    International Nuclear Information System (INIS)

    This report describes tests conducted in an approximately 9-ft diameter test tank situated outside the 336 building in Hanford's 300 area. The tests were performed to measure the ability of jets of grout slurry to mobilize and mix simulated tank sludge. The technique is intended for in situ immobilization of tank waste heels. The current approach uses a single, rotated, larger-diameter nozzle driven at lower pressure. Due to the larger diameter, the potential for plugging is reduced and the effective radius around an injection point over which the jet is effective in mobilizing sludge from the tank bottom can be made larger. A total of three grout injection tests were conducted in a 9-ft diameter tank. In each case, a 2-in. layer of kaolin clay paste was placed on a dry tank floor to simulate a sludge heel. The clay was covered with 4 inches of water. The grout slurry, consisting of Portland cement, class F fly ash, and eater, was prepared and delivered by an offsite vendor. In the third test, the sludge in half of the tank was replaced by a layer of 20x50 mesh zeolite, and bentonite clay was added to the grout formulation. After injection, the grout was allowed to set and then the entire grout monolith was manually broken up and excavated using a jack hammer. Intact pieces of clay were visually apparent due to a sharp color contrast between the grout and clay. Remaining clay deposits were collected and weighed and suspended clay pieces within the monolith were photographed. The mobilization performance of the grout jets exceeded expectations

    In 1983, Fitzsimmons et al. reported four brothers with an unrecognized disorder characterized by intellectual disability, spastic paraplegia, and palmo-plantar hyperkeratosis (OMIM 309500). In this report, we describe a family in which two males, maternal half-brothers, had learning disabilities. Both patients also showed spasticity in the lower limbs and palmo-plantar hyperkeratosis. The mother of the affected boys had learning difficulties but did not show any dermatological symptoms. This report confirms that the association of features reported by Fitzsimmons et al. is a distinct entity and further suggests an X-linked mode of inheritance. PMID:23613454

    Injuries or burns to the dorsum of the first metatarsophalangeal (MTP) joint may develop scar formation, resulting in hyperextension contracture. Surgical correction of the deformity often produces a secondary defect. The purpose of this study is to report on the use of the medial plantar hallucal artery dorsal perforator flap for the treatment of such defect. From February 2010 to June 2011, 16 patients were treated. The mean preoperative hyperextension of the first MTP joint was 48 degrees. The mean size of the defects was 3.6 × 6 cm. The mean flap size was 4 × 6.5 cm. The mean pedicle length was 4 cm. All flaps survived completely. Patient follow-up lasted a mean of 14 months. At the final follow-up, the mean hyperextension of the first MTP joint was 9 degrees. After surgery, the mean Foot Function Index improved from 62 to 7. Almost all patients were satisfied with the results. Transferring the medial plantar hallucal artery dorsal perforator flap is a useful and reliable technique for the reconstruction of the secondary defect on the first MTP joint. PMID:25275474

  3. Classification of forefoot plantar pressure distribution in persons with diabetes: a novel perspective for the mechanical management of diabetic foot?

    Directory of Open Access Journals (Sweden)

    Kevin Deschamps

    Full Text Available BACKGROUND: The aim of this study was to identify groups of subjects with similar patterns of forefoot loading and verify if specific groups of patients with diabetes could be isolated from non-diabetics. METHODOLOGY/PRINCIPAL FINDINGS: Ninety-seven patients with diabetes and 33 control participants between 45 and 70 years were prospectively recruited in two Belgian Diabetic Foot Clinics. Barefoot plantar pressure measurements were recorded and subsequently analysed using a semi-automatic total mapping technique. Kmeans cluster analysis was applied on relative regional impulses of six forefoot segments in order to pursue a classification for the control group separately, the diabetic group separately and both groups together. Cluster analysis led to identification of three distinct groups when considering only the control group. For the diabetic group, and the computation considering both groups together, four distinct groups were isolated. Compared to the cluster analysis of the control group an additional forefoot loading pattern was identified. This group comprised diabetic feet only. The relevance of the reported clusters was supported by ANOVA statistics indicating significant differences between different regions of interest and different clusters. CONCLUSION/S SIGNIFICANCE: There seems to emerge a new era in diabetic foot medicine which embraces the classification of diabetic patients according to their biomechanical profile. Classification of the plantar pressure distribution has the potential to provide a means to determine mechanical interventions for the prevention and/or treatment of the diabetic foot.

  4. The conundrum of calcaneal spurs: do they matter?

    2013-12-30

    Background: Chronic plantar heel pain is a common and potentially debilitating condition, often caused by plantar fasciitis. Plantar calcaneal spurs were originally considered the cause of plantar fasciitis but are now regarded as an incidental finding by most authors. We aimed to test this hypothesis and to investigate predisposing factors for the development of spurs. Methods: We reviewed all lateral ankle X rays taken in our institution over a 6-month period and identified all X rays demonstrating calcaneal spurs. Then, we identified a similar number of age- and sex-matched controls without spurs. We contacted both groups by telephone and compared symptoms of heel pain, plantar fasciitis, associated comorbidities, and foot and ankle outcome scores (FAOSs). Results: We reviewed the X rays of 1103 consecutive patients and found a spur prevalence of 12.4%, more common in women and older patients. Questioning of the spur group and control group found a higher body mass index in the spur group. Patients with spurs were 4 times more likely to have diabetes mellitus and 10 times more likely to have lower-limb osteoarthritis. Patients with spurs had more foot pain and poorer FAOS than the control group, even when patients with plantar fasciitis were excluded. Conclusion: Our results demonstrate that the presence of a plantar calcaneal spur may be an indicator of foot pain independent of plantar fasciitis. Although spurs may not cause foot pain themselves, they may be an indication of other associated conditions. Clinical relevance: We have demonstrated the relevance of a radiographic finding once considered irrelevant.

    2014-01-01

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

    Changes in the mechanical properties of the plantar soft tissue in people with diabetes may contribute to the formation of plantar ulcers. Such ulcers have been shown to be in the causal pathway for lower extremity amputation. The hydraulic plantar soft tissue reducer (HyPSTER) was designed to measure in vivo, rate-dependent plantar soft tissue compressive force and three-dimensional deformations to help understand, predict, and prevent ulcer formation. These patient-specific values can then be used in an inverse finite element analysis to determine tissue moduli, and subsequently used in a foot model to show regions of high stress under a wide variety of loading conditions. The HyPSTER uses an actuator to drive a magnetic resonance imaging-compatible hydraulic loading platform. Pressure and actuator position were synchronized with gated magnetic resonance imaging acquisition. Achievable loading rates were slower than those found in normal walking because of a water-hammer effect (pressure wave ringing) in the hydraulic system when the actuator direction was changed rapidly. The subsequent verification tests were, therefore, performed at 0.2 Hz. The unloaded displacement accuracy of the system was within 0.31%. Compliance, presumably in the system's plastic components, caused a displacement loss of 5.7 mm during a 20-mm actuator test at 1354 N. This was accounted for with a target to actual calibration curve. The positional accuracy of the HyPSTER during loaded displacement verification tests from 3 to 9 mm against a silicone backstop was 95.9% with a precision of 98.7%. The HyPSTER generated minimal artifact in the magnetic resonance imaging scanner. Careful analysis of the synchronization of the HyPSTER and the magnetic resonance imaging scanner was performed. With some limitations, the HyPSTER provided key functionality in measuring dynamic, patient-specific plantar soft tissue mechanical properties. PMID:26405098

    Full Text Available Abstract Background Osteoporosis is a bone disease that can reduce both bone mass and bone strength. It can cause serious fractures of bones, along with causing significant and even devastating physical, psychological and financial consequences for patients and their family members. Many reports have revealed that the prevalence of decreased bone density is higher in schizophrenic patients than in the non-psychological diseased population. The previous report of our group revealed that chronic schizophrenia patients have poorer BUA levels since they were young as compared to the general community population. Hyperprolactinemia and antipsychotics are reported to be among the risk factors for osteoporosis in chronic schizophrenic patients. Methods 93 schizophrenic patients with severely poor adjusted BUA values and 93 age and gender matched patients with normal adjusted BUA values from a previous survey study were selected. Data were collected via questionnaires and via reviews of antipsychotic medications. Blood samples were drawn, and serum levels of prolactin, estradiol, testosterone, magnesium, calcium, phosphate, osteocalcin, Cross-linked N-teleopeptide of type I collagen (NTX, thyroid hormone and parathyroid hormone were checked. The association between BUA levels and serum levels of the above items, along with the type of received antipsychotic medication, was evaluated. Results There was no significant association found between reduced BUA levels and serum prolactin, calcium, phosphate, osteocalcin, NTX, thyroid stimulating hormone and parathyroid hormone levels. There was also no association between BUA levels and types of currently received antipsychotics. There was no association between BUA levels and menstruation condition in female patients. Hypermagnesemia had a borderline association with classical and combined (classical and atypical antipsychotic medications in male patients. Nevertheless, hypermagnesemia is a significant

  14. Tradeoffs between impact loading rate, vertical impulse and effective mass for walkers and heel strike runners wearing footwear of varying stiffness.

    2015-05-01

    Humans experience repetitive impact forces beneath the heel during walking and heel strike running that cause impact peaks characterized by high rates and magnitudes of loading. Impact peaks are caused by the exchange of momentum between the ground and a portion of the body that comes to a full stop (the effective mass) during the period of the impact peak. A number of factors can influence this exchange of momentum, including footwear stiffness. This study presents and tests an impulse-momentum model of impact mechanics which predicts that effective mass and vertical impulse is greater in walkers and heel strike runners wearing less stiff footwear. The model also predicts a tradeoff between impact loading rate and effective mass, and between impact loading rate and vertical impulse among individuals wearing footwear of varying stiffness. We tested this model using 19 human subjects walking and running in minimal footwear and in two experimental footpads. Subjects walked and ran on an instrumented treadmill and 3D kinematic data were collected. As predicted, both vertical impulse (walking: F(2,54)=52.0, p=2.6E-13; running: F(2,54)=25.2, p=1.8E-8) and effective mass (walking: F(2,54)=12.1, p=4.6E-5; running: F(2,54)=15.5, p=4.7E-6) increase in less stiff footwear. In addition, there is a significant inverse relationship between impact loading rate and vertical impulse (walking: r=-0.88, ploading rate and effective mass (walking: r=-0.88, p<0.0001; running: r=-0.82, p<0.0001). The tradeoff relationships documented here raise questions about how and in what ways the stiffness of footwear heels influence injury risk during human walking and running. PMID:25814181

  19. Do we really need radiographic assessment for the diagnosis of non-specific heel pain (calcaneal apophysitis) in children?

    Non-specific heel pain (calcaneal apophysitis) is a common disorder, particularly in physically active growing children. Foot radiographs are usually obtained as part of the clinical evaluation in routine orthopaedic practice. However, there is still controversy about the specific findings on radiographs, and it is unclear what information is present on radiographs that may alter the diagnosis and management. The purpose of this study was to review a consecutive series of patients with the diagnosis of calcaneal apophysitis to assess the yield of routine radiographs of the foot. A prospective study was performed on 61 consecutive patients with a diagnosis of calcaneal apophysitis in a single-surgeon practice. Standard anteroposterior and lateral weight-bearing foot radiographs were obtained for each patient. Seventy-one sets of foot radiographs were reviewed to determine whether radiographs had an impact on diagnosis and management. Patients with antecedent trauma, penetrating injury, foot deformity, achilles tendonitis, bursitis and infections were excluded from the study. Seventy foot radiographs were considered to be normal. The radiographs changed the diagnosis in only one patient, in whom a simple bone cyst of the calcaneous was seen. Calcaneal apophysitis is a self-limiting disease, and patients can be treated conservatively. Neither the sclerosis nor the fragmentation of the apophysis could be used to establish the diagnosis of calcaneal apophysitis. Therefore, obtaining radiographs as an initial step in their evaluation does not seem to be justified. (orig.)

    Full Text Available This study was designed to investigate the sites of potential specific modulations in the neural control of lengthening and subsequent isometric maximal voluntary contractions (MVCs versus purely isometric MVCs of the plantar flexor muscles, when there is enhanced torque during and following stretch. Ankle joint torque during maximum voluntary plantar flexion was measured by a dynamometer when subjects (n = 10 lay prone on a bench with the right ankle tightly strapped to a foot-plate. Neural control was analysed by comparing soleus motor responses to electrical nerve stimulation (M-wave, V-wave, electrical stimulation of the cervicomedullary junction (CMEP and transcranial magnetic stimulation of the motor cortex (MEP. Enhanced torque of 17 ± 8% and 9 ± 8% was found during and 2.5-3 s after lengthening MVCs, respectively. Cortical and spinal responsiveness was similar to that in isometric conditions during the lengthening MVCs, as shown by unchanged MEPs, CMEPs and V-waves, suggesting that the major voluntary motor pathways are not subject to substantial inhibition. Following the lengthening MVCs, enhanced torque was accompanied by larger MEPs (p ≤ 0.05 and a trend to greater V-waves (p ≤ 0.1. In combination with stable CMEPs, increased MEPs suggest an increase in cortical excitability, and enlarged V-waves indicate greater motoneuronal output or increased stretch reflex excitability. The new results illustrate that neuromotor pathways are altered after lengthening MVCs suggesting that the underlying mechanisms of the enhanced torque are not purely mechanical in nature.

  1. Plantar talar head contusions and osteochondral fractures: associated findings on ankle MRI and proposed mechanism of injury

    International Nuclear Information System (INIS)

    To evaluate the significance of plantar talar head injury (PTHI) in predicting osseous and soft tissue injuries on ankle MRI. The IRB approved this HIPAA-compliant retrospective study. The study group consisted of 41 ankle MRIs with PTHI that occurred at our institution over a 5 1/2 year period. Eighty MRIs with bone injuries in other locations matched for age, time interval since injury, and gender formed a control group. Injuries to the following structures were recorded: medial malleolus, lateral malleolus/distal fibula, posterior malleolus, talus, calcaneus, navicular, cuboid, lateral, medial and syndesmotic ligaments, spring ligament complex, and extensor digitorum brevis (EDB) muscle. Twenty separate logistic regressions determined which injuries PTHI predicted, using the Holm procedure to control for family-wise alpha at 0.05. PTHI strongly predicted the occurrence of injuries involving the anterior process of the calcaneus [24 % of cases, odds ratio (OR) 12.66], plantar components of the spring ligament (27 %, OR 9.43), calcaneal origin of the EDB and attachment of the dorsolateral calcaneocuboid ligament (22 %, OR 7.22), cuboid (51 %, OR 6.58), EDB (27 %, OR 5.49), anteromedial talus (66 %, OR 4.78), and posteromedial talus (49 %, OR 4.48). PTHI strongly predicted lack of occurrence of syndesmotic ligament injury (OR 19.6). The PTHI group had a high incidence of lateral ligamentous injury (78 %), but not significantly different from the control group (53 %). PTHI is strongly associated with injury involving the transverse tarsal joint complex. We hypothesize it results from talo-cuboid and/or talo-calcaneal impaction from a supination injury of the foot and ankle. (orig.)

    2012-10-01

    Full Text Available Abstract Background Offloading plantar pressure is a key strategy for the prevention or healing of neuropathic plantar ulcers in diabetes. Non-removable walking casts, such as total contact casts, are currently considered the gold-standard for offloading this type of wound. However, alternative methods for offloading that are more cost effective and easier to use are continually being sought. The aim of this study was to evaluate the capacity of the DH Pressure Relief Shoe™ to offload high pressure areas under the neuropathic foot in diabetes. Methods A within-subjects, repeated measures design was used. Sixteen participants with diabetic peripheral neuropathy were recruited and three footwear conditions were evaluated in a randomised order: a canvas shoe (the control, the participants’ own standard shoe, and the DH Pressure Relief Shoe™. The primary outcome was peak plantar pressure, measured using the pedar-X® mobile in-shoe system between the three conditions. Results Data analysis was conducted on 14 out of the 16 participants because two participants could not complete data collection. The mean peak pressure values in kPa (±SD for each condition were: control shoe 315.9 (±140.7, participants’ standard shoe 273.0 (±127.1 and DH Pressure Relief Shoe™ 155.4 (±89.9. There was a statistically significant difference in peak plantar pressure between the DH Pressure Relief Shoe™ compared to both the control shoe (p = 0.002 and participants’ standard shoe (p = 0.001. The DH Pressure Relief Shoe™ decreased plantar pressures by 51% compared to the control shoe and by 43% compared to participants’ standard shoe. Importantly, for a couple of study participants, the DH Pressure Relief Shoe™ appeared unsuitable for day-to-day wearing. Conclusions The DH Pressure Relief Shoe™ reduced plantar pressures more than the other two shoe conditions. The DH Pressure Relief Shoe™ may be a useful alternative to current offloading

    This is a case report of malignant melanoma that occurred in an area of chronic radiodermatitis on the sole of the foot. A 55-year-old woman was irradiated for corns on the soles of both feet in 1967. Dermatoplasty was performed for hyperkeratosis of the sole of the right foot in 1988, but a tumor developed on the right heel in 1998, and grew larger. The histological findings suggested malignant melanoma, and the tumor including the periosteum, was removed. The patient was treated with four cycles of adjuvant chemotherapy (dacarbazine, nimustine hydrochloride, and vincristine), and no signs of recurrence one year after surgery. Based on a review of the literature, there appears to be little relation between melanoma and irradiation, and this is only the second case ever reported in Japan. (K.H.)

    Multidisciplinary field projects can be very useful to a more fundamental understanding of the world around us, though these projects are not as common as they should be. In particular, the combination of archeology and geology combines our understanding of human behavior and human use of the landscape with an intimate knowledge of geologic processes and the materials available for human use in order to gain a broader understanding of human-Earth interaction. Here we present data from a cross-disciplinary project that uses a common dataset, archeological artifacts, to explore the anthropological and geologic implications of useage patterns. Archeological excavations and surveys conducted by the Office of Contract Archeology in 2007 along the route of the proposed international border fence reveal patterns of use of geologic materials by Archaic, Formative and Protohistoric Native Americans in the Boot Heel of southwestern New Mexico. Thousands of artifacts were recorded in multiple sites from Guadalupe Pass in the southern Peloncillo Mountains to the Carrizalillo Hills west of Columbus. We identified the lithologies of artifacts, ranging from projectile points to groundstones, and then constructed material movement maps based on either known procurement sites ("quarries") or outcrops identified as the closest source to a given site for each lithology. Not unexpectedly, the majority of the rock types utilized by native peoples are local siliceous volcanic materials. However, several artifacts constructed from obsidian were transported into the region from northern Mexico and eastern Arizona, indicating long-distance travel and/or trade routes. We also examine useage pattern difference between Archaic, Formative and Protohistoric sites. Additionally, a dramatic change in distribution of sources for geologic materials occurs between one pre-Spanish site and one post-Spanish site that are adjacent to one another.

  10. Utilization of the MPI Process for in-tank solidification of heel material in large-diameter cylindrical tanks

    A major problem faced by the US Department of Energy is remediation of sludge and supernatant waste in underground storage tanks. Exhumation of the waste is currently the preferred remediation method. However, exhumation cannot completely remove all of the contaminated materials from the tanks. For large-diameter tanks, amounts of highly contaminated ``heel'' material approaching 20,000 gal can remain. Often sludge containing zeolite particles leaves ``sand bars'' of locally contaminated material across the floor of the tank. The best management practices for in-tank treatment (stabilization and immobilization) of wastes require an integrated approach to develop appropriate treatment agents that can be safely delivered and mixed uniformly with sludge. Ground Environmental Services has developed and demonstrated a remotely controlled, high-velocity jet delivery system termed, Multi-Point-Injection (MPI). This robust jet delivery system has been field-deployed to create homogeneous monoliths containing shallow buried miscellaneous waste in trenches [fiscal year (FY) 1995] and surrogate sludge in cylindrical (FY 1998) and long, horizontal tanks (FY 1999). During the FY 1998 demonstration, the MPI process successfully formed a 32-ton uniform monolith of grout and waste surrogates in about 8 min. Analytical data indicated that 10 tons of zeolite-type physical surrogate were uniformly mixed within a 40-in.-thick monolith without lifting the MPI jetting tools off the tank floor. Over 1,000 lb of cohesive surrogates, with consistencies similar to Gunite and Associated Tank (GAAT) TH-4 and Hanford tank sludges, were easily intermixed into the monolith without exceeding a core temperature of 100 F during curing.

    Greater lower extremity joint stiffness may be related to the development of tibial stress fractures in runners. Musculotendinous stiffness is the largest contributor to joint stiffness, but it is unclear what factors contribute to musculotendinous stiffness. The purpose of this study was to compare plantar flexor musculotendinous stiffness, architecture, geometry, and Achilles tendon stiffness between male runners with and without a history of tibial stress fracture. Nineteen healthy runners (age = 21 ± 2.7 years; mass = 68.2 ± 9.3 kg; height = 177.3 ± 6.0 cm) and 19 runners with a history of tibial stress fracture (age = 21 ± 2.9 years; mass = 65.3 ± 6.0 kg; height = 177.2 ± 5.2 cm) were recruited from community running groups and the university's varsity and club cross-country teams. Plantar flexor musculotendinous stiffness was estimated from the damped frequency of oscillatory motion about the ankle follow perturbation. Ultrasound imaging was used to measure architecture and geometry of the medial gastrocnemius. Dependent variables were compared between groups via one-way ANOVAs. Previously injured runners had greater plantar flexor musculotendinous stiffness (P < .001), greater Achilles tendon stiffness (P = .004), and lesser Achilles tendon elongation (P = .003) during maximal isometric contraction compared with healthy runners. No differences were found in muscle thickness, pennation angle, or fascicle length. PMID:25320911

    The outcome of corticosteroid injection (CSI) and extracorporeal shock wave therapy (ESWT) as primary treatment of acute plantar fasciitis has been debated. The purpose of the present study was to evaluate and compare the therapeutic effects of CSI and ESWT in patients with acute (plantar fasciitis. Of the 116 eligible patients, 68 were randomized to 2 equal groups of 34 patients, each undergoing either ESWT or CSI. The ESWT method included 2000 impulses with energy of 0.15 mJ/mm(2) and a total energy flux density of 900 mJ/mm(2) for 3 consecutive sessions at 1-week intervals. In the CSI group, 40 mg of methyl prednisolone acetate plus 1 mL of lidocaine 2% was injected into the maximal tenderness point at the inframedial calcaneal tuberosity. The success and recurrence rates and pain intensity measured using the visual analog scale, were recorded and compared at the 3-month follow-up visit. The pain intensity had reduced significantly in all patients undergoing either technique. However, the value and trend of pain reduction in the CSI group was significantly greater than those in the ESWT group (p  .05). Both ESWT and CSI can be used as the primary and/or initial treatment option for treating patients with acute plantar fasciitis; however, the CSI technique had better therapeutic outcomes.

  3. Recurrent multifocal chronic osteitis in children

    International Nuclear Information System (INIS)

    We have studied retrospectively a series of 10 children presenting with chronic multifocal osteomyelitis (8 girls, 2 boys, 7 to 16 years). All patients had plain films, bone scintigraphies and histological studies. Three had CT scan and/or MRI. Compared with literature data, we observed only one case of palmo-plantar pustulosis and only 2 cases of lysis of the medial extremity of the clavicle; in addition, we report one case of lateral extremity of the clavicle and 2 vertebral locations. The radiological pattern was typical: at the beginning of the disease, plain films showed lytic areas which became progressively osteosclerotic with enlargement of the bone. In all the cases, bone scintigraphy revealed high uptake areas which were often infra-clinical. The diagnosis was delayed from 3 months to 3 years. This emphasizes the difficulty of the diagnosis which relies on the association of clinical, biological and radiological elements. Biopsies are required to rule out an infectious bacterial osteomyelitis or a tumoral process. The pathogenesis of OCMR remains unknown, but the relation with the SAPHO (synovitis, acne, pustulosis, Hyperostosis, osteitis) syndrome is general accepted because of the similar features of the osteitis. The long term follow up appears to be uncertain: 6 of our patients are still symptomatic after five years despite anti inflammatory treatment. (authors)

Methods: Dynamic plantar pressure of 24 nurses who have worked less than one year or more than ten years were measured by plantar pressure distribution measurement system respectively. Results:Maximum plantar pressure of all the nurses was distributed around the second and third metatarsal bones, maximum impulse was around the anterior part of the feet. There was significant difference for the same nurse between plantar pressure and impulse in the morning and afternoon (P<0.05). Impulse and pressure in the afternoon were remarkably higher than these in the morning (P<0.05). Pressure and im-pulse of the nurse with high seniorities were higher than these of the ones with junior seniorities notably (P<0.05). Conclusion:Professional characters make the nurses suffering from higher plantar pressure and impulse, which could cause foot damage easily.

  5. The validity and reliability of a portable slip meter for determining floor slipperiness during simulated heel strike.

    A previously developed test rig was used as starting point for designing a portable slip meter with two new features. First, an inflatable pneumatic test wheel, consisting of six slider units, was introduced as the impacting contact element relative to floor surface. Second, an inductive trigger was built into the system to facilitate a precise timing of the slider-floor contact during the test. This new test rig was designed to measure transitional friction properties of contaminated floor surfaces during simulated heel strike, which is considered the most critical phase of gait from the slip and fall point of view. Another objective was to quantify the validity and reliability of this test method in the laboratory, but not yet in the field. The measurement process was evaluated on eight wet and oily floor surfaces (vinyl and ceramic tile floorings) using two slider materials (plain, profiled), two normal loads (100, 200 N), and two sliding velocities (0.15, 0.30 m/s) as independent variables. The outputs of the portable slip meter, in terms of transitional friction coefficients, were compared to force platform-based friction values and to slip resistance values obtained with a slip simulator apparatus for laboratory testing of shoes and floor surfaces. The outputs were also evaluated against slipperiness ratings made by three male subjects in paired comparison trials, in which the subjects walked over eight wet floor surfaces wearing shoes with the plain soling material. The results showed that test option 200 N and 0.15m/s led to optimum validity despite its tendency to promote frictional vibrations (stick-slip) in the contact surface. Compared to the lower sliding speed, the higher speed reduced both stick-slip and measurement bias. Test option 200 N and 0.30 m/s was the most reliable one in this experiment. It yielded lower friction coefficients than any other test option and reduced the likelihood of underestimating slip and fall hazards. The results implied

    Humans utilise elastic tendons of lower limb muscles to store and return energy during walking, running and jumping. Anuran and insect species use skeletal structures and/or dynamics in conjunction with similarly compliant structures to amplify muscle power output during jumping. We sought to examine whether human jumpers use similar mechanisms to aid elastic energy usage in the plantar flexor muscles during maximal vertical jumping. Ten male athletes performed maximal vertical squat jumps. Three-dimensional motion capture and a musculoskeletal model were used to determine lower limb kinematics that were combined with ground reaction force data in an inverse dynamics analysis. B-mode ultrasound imaging of the lateral gastrocnemius (GAS) and soleus (SOL) muscles was used to measure muscle fascicle lengths and pennation angles during jumping. Our results highlighted that both GAS and SOL utilised stretch and recoil of their series elastic elements (SEEs) in a catapult-like fashion, which likely serves to maximise ankle joint power. The resistance of supporting of body weight allowed initial stretch of both GAS and SOL SEEs. A proximal-to-distal sequence of joint moments and decreasing effective mechanical advantage early in the extension phase of the jumping movement were observed. This facilitated a further stretch of the SEE of the biarticular GAS and delayed recoil of the SOL SEE. However, effective mechanical advantage did not increase late in the jump to aid recoil of elastic tissues. PMID:26685172

    Peripheral neuropathic pain is a consequence of an injury/disease of the peripheral nerves. The mechanisms involved in its pathophysiology are not entirely understood. To better understand the mechanisms involved in the development of peripheral nerve injury-induced neuropathic pain, more experimental models are required. Here, we developed a novel peripheral neuropathic pain model in mice by using a minimally invasive surgery and medial plantar nerve ligation (MPNL). After MPNL, mechanical allodynia was established, and mice quickly recovered from the surgery without any significant motor impairment. MPNL causes an increased expression of ATF-3 in the sensory neurons. At 14 days after surgery, gabapentin was capable of reversing the mechanical allodynia, whereas anti-inflammatory drugs and opioids were ineffective. MPNL-induced neuropathic pain was mediated by glial cells activation and the production of TNF-α and IL-6 in the spinal cord. These results indicate MPNL as a reasonable animal model for the study of peripheral neuropathic pain, presenting analgesic pharmacological predictivity to clinically used drugs. The results also showed molecular phenotypic changes similar to other peripheral neuropathic pain models, with the advantage of a lack of motor impairment. These features indicate that MPNL might be more appropriate for the study of neuropathic pain than classical models. PMID:27230787

    Full Text Available Power training has been proposed as a more effective type of resistance training for older adults for functional performance. It is not yet known whether older adults respond appropriately to instructions for power versus strength training. The purpose of this study was to determine the velocity during strength and power training, with elastic resistance bands, in older adults attending a geriatric rehabilitation day program. It was hypothesized that power training would be faster than strength training, but that there would be large interindividual differences. Nine older patients (70 to 86 years performed power and strength training of the ankle dorsiflexor and plantar flexor muscles using elastic resistance bands. Training sessions were filmed to assess the velocity of training. Power training occurred at faster velocities as compared to strength training (P<0.01 for both muscle groups. However, a wide variation was observed between participants in the training velocities. Older adults attending geriatric rehabilitation do have the potential to develop faster contractions during power training as compared to strength training. Nevertheless, the actual velocities achieved differed between individuals. This could explain some of the mixed findings of studies on power training. Hence, researchers should monitor velocity when comparing different types of resistance training.

    Objectives This study tested the hypothesis that impairments in lower limb maximal strength and voluntary activation (VA) are exacerbated following match-play tennis in hot compared with cool conditions. Methods Torque and VA were evaluated during brief (5 s) and sustained (20 s) maximal voluntary isometric contractions of the knee extensors (KE) and plantar flexors (PF) in 12 male tennis players before (pre) and after (post, 24 h and 48 h) ∼115 min of play in hot (∼37°C) and cool (∼22°C) conditions. Results Rectal temperature was higher following play in hot than in cool (∼39.2 vs ∼38.5°C; ptennis in hot and cool conditions due to the development of peripheral fatigue. The larger and persistent KE strength losses observed under heat stress are associated with greater levels of central fatigue especially during sustained contractions. PMID:24668379

    Comparing plantar pressure measurements (PPM) of a patient following an intervention or between a reference group and a patient-group is common practice in clinical gait analysis. However, this process is often time consuming and complex, and commercially available software often lacks powerful visualization and interpretation tools. In this paper, we propose a simple method for displaying pixel-level PPM deviations relative to a so-called reference PPM pattern. The novel method contains 3 distinct stages: (1) a normalization of pedobarographic fields (for foot length and width), (2) a pixel-level z-score based calculation and, (3) color coding of the normalized pedobarographic fields. The methodological steps associated to this novel method are precisely described and clinical output illustrated. We believe that the advantages of the novel method cover several domains. The strongest advantage of the novel method is that it provides a straightforward visual interpretation of PPM without decreasing the resolution perspective. A second advantage is that it may guide the selection of a local mapping technique (data reduction technique). Finally, it may be easily used as education tool during the therapist-patient interaction. PMID:25743774

    We often describe Denmark and the other Nordic countries as successful when it comes to equality between the sexes. However, is this true? If we survey the management of Danish upper secondary schools, only one third of the top managers are women, an inequality that will not necessarily change in...... the coming years. The demand for management is increasing and should result in new career possibilities for all, but in fact we may see a new form of gendered division of labor, a scenario where men as top managers (COEs or A-leaders) deal with externally oriented economic and strategic tasks and...
