    Spinal cord injury (SCI) can have a range of debilitating effects and permanently alter the capabilities and quality of life of survivors.The first specialized centers of care for SCI were established in 1944 and since then an increasing amount of research has been carried out in this area.Despite this,the present treatment and care levels for SCI are not comparable to those in other areas of medicine.In the clinic,the aim of SCI treatment is primarily to limit secondary damage by reducing compression in trauma spots and stabilizing the spinal column.Currently,no effective strategy for functional recovery is offered.In this review,we focus on research progress on the molecular mechanisms underlying SCI,and assess the treatment outcomes of SCI in animal models,i.e.,neurotrophins and stem cells are discussed as pre-clinical therapies in animal models.We also assess the resources available and national research projects carried out on SCI in China in recent years,as well as making recommendations for the future allocation of funds in this area.

    The rapid growth in data sharing presents new opportunities across the spectrum of biomedical research. Global efforts are underway to develop practical guidance for implementation of data sharing and open data resources. These include the recent recommendation of 'FAIR Data Principles', which assert that if data is to have broad scientific value, then digital representations of that data should be Findable, Accessible, Interoperable and Reusable (FAIR). The spinal cord injury (SCI) research field has a long history of collaborative initiatives that include sharing of preclinical research models and outcome measures. In addition, new tools and resources are being developed by the SCI research community to enhance opportunities for data sharing and access. With this in mind, the National Institute of Neurological Disorders and Stroke (NINDS) at the National Institutes of Health (NIH) hosted a workshop on October 5-6, 2016 in Bethesda, MD, in collaboration with the Open Data Commons for Spinal Cord Injury (ODC-SCI) titled "Preclinical SCI Data: Creating a FAIR Share Community". Workshop invitees were nominated by the workshop steering committee (co-chairs: ARF and VPL; members: AC, KDA, MSB, KF, LBJ, PGP, JMS), to bring together junior and senior level experts including preclinical and basic SCI researchers from academia and industry, data science and bioinformatics experts, investigators with expertise in other neurological disease fields, clinical researchers, members of the SCI community, and program staff representing federal and private funding agencies. The workshop and ODC-SCI efforts were sponsored by the International Spinal Research Trust (ISRT), the Rick Hansen Institute, Wings for Life, the Craig H. Neilsen Foundation and NINDS. The number of attendees was limited to ensure active participation and feedback in small groups. The goals were to examine the current landscape for data sharing in SCI research and provide a path to its future. Below are

  8. Spinal Cord Injury Caused by Stab Wounds: Incidence, Natural History, and Relevance for Future Research.

    2016-08-01

    Spinal cord injury caused by stab wounds (SCISW) results from a partial or complete transection of the cord, and presents opportunities for interventional research. It is recognized that there is low incidence, but little is known about the natural history or the patient's suitability for long-term clinical outcome studies. This study aims to provide population-based evidence of the demographics of SCISW, and highlight the issues regarding the potential for future research. The database of the Queen Elizabeth National Spinal Injuries Unit (QENSIU), the sole center for treating SCI in Scotland, was reviewed between 1994 and 2013 to ascertain the incidence, demographics, functional recovery, and mortality rates for new SCISW. During this 20 year period, 35 patients with SCISW were admitted (97.1% male, mean age 30.0 years); 31.4% had a cervical injury, 60.0% had a thoracic injury, and 8.6% had a lumbar injury. All had a neurological examination, with 42.9% diagnosed as motor complete on admission and 77.1% discharged as motor incomplete. A total of 70.4% of patients with an American Spinal Injury Association Impairment Scale (AIS) level of A to C on admission had an improved AIS level on discharge. Nine (25.7%) patients have died since discharge, with mean life expectancy for these patients being 9.1 years after injury (20-65 years of age). Patients had higher levels of comorbidities, substance abuse, secondary events, and poor compliance compared with the general SCI population, which may have contributed to the high mortality rate observed post-discharge. The low incidence, heterogeneous nature, spontaneous recovery rate, and problematic follow-up makes those with penetrating stab injuries of the spinal cord a challenging patient group for SCI research.

    2016-08-12

    Increased survival after spinal cord injury (SCI) worldwide has enhanced the need for quality data that can be compared and shared between centers, countries, as well as across research studies, to better understand how best to prevent and treat SCI. Such data should be standardized and be able to be uniformly collected at any SCI center or within any SCI study. Standardization will make it possible to collect information from larger SCI populations for multi-center research studies. With this aim, the international SCI community has obtained consensus regarding the best available data and measures for use in SCI clinical practice and research. Reporting of SCI data is likewise standardized. Data elements are continuously updated and developed using an open and transparent process. There are ongoing internal, as well as external review processes, where all interested parties are encouraged to participate. The purpose of this review paper is to provide an overview of the initiatives to standardize data including the International Spinal Cord Society's International SCI Data Sets and the National Institutes of Health, National Institute of Neurological Disorders and Stroke Common Data Elements Project within SCI and discuss future opportunities.

It is estimated that only 14% of health-related scientific discoveries enter into medical practice and that it takes an average of 17 years for them to do so. The transition from basic research to clinical knowledge and from clinical knowledge to practice or implementation is so fraught with obstacles that these transitions are often referred to as “valleys of death”. The Rick Hansen Institute has developed a unique praxis model for translational research in the field of spinal cord injury (SCI. The praxis model involves three components. The first is a coordinated program strategy of cure, care, consumer engagement, and commercialization. The second is a knowledge cycle that consists of four phases, ie, environmental scanning, knowledge generation and synthesis, knowledge validation, and implementation. The third is the provision of relevant resources and infrastructure to overcome obstacles in the “valleys of death”, ie, funding, clinical research operations, informatics, clinical research and best practice implementation, consumer engagement, collaborative networks, and strategic partnerships. This model, which is to be independently evaluated in 2018 to determine its strengths and limitations, has been used to advance treatments for pressure ulcers in SCI. The Rick Hansen Institute has developed an innovative solution to move knowledge into action by

    Spinal cord injury(SCI) is a severe trauma to the central nervous system(CNS). This article reviews recent advances in cellular transplantation to treat SCI. Transplanted cells can supply new neurons to replace injured ones, promote regeneration of axons and myelin sheath, modulate the inflammatory response, and thus promote recovery from traumatic injury of the CNS. Cellular transplantation is a promising potential method for the treatment of SCI.

    Full Text Available This study reviews the literature concerning possible therapeutic approaches for spinal cord injury. Spinal cord injury is a disabling and irreversible condition that has high economic and social costs. There are both primary and secondary mechanisms of damage to the spinal cord. The primary lesion is the mechanical injury itself. The secondary lesion results from one or more biochemical and cellular processes that are triggered by the primary lesion. The frustration of health professionals in treating a severe spinal cord injury was described in 1700 BC in an Egyptian surgical papyrus that was translated by Edwin Smith; the papyrus reported spinal fractures as a ''disease that should not be treated.'' Over the last biological or pharmacological treatment method. Science is unraveling the mechanisms of cell protection and neuroregeneration, but clinically, we only provide supportive care for patients with spinal cord injuries. By combining these treatments, researchers attempt to enhance the functional recovery of patients with spinal cord injuries. Advances in the last decade have allowed us to encourage the development of experimental studies in the field of spinal cord regeneration. The combination of several therapeutic strategies should, at minimum, allow for partial functional recoveries for these patients, which could improve their quality of life.

    Systematic, thematic, narrative review of qualitative literature. To systematically review qualitative research that explores the impact of spinal cord injury (SCI) on the gendered experience of men with SCI. A systematic search of databases and hand search of relevant journals to provide a thematic narrative review of articles, providing sufficient depth of information, relevant participant quotes and phenomenological insight into the gendered experience of men with SCI. Identified studies are summarised and common themes extracted and discussed in relation to relevant literature on masculinity, disability and health. Eight papers, representing four separate studies met the review criteria for relevance and rigour. Three broad, overlapping themes describing the gendered experience of men with SCI were identified: 'lost masculinity', outlining the impact of SCI on traditional masculine identity, 'fighting back', describing the battle to regain and reclaim masculinity and integrate disability into a revised identity and 'beyond hegemony', referring to possibilities beyond adherence to traditional masculine scripts. This review demonstrates a lack of explicit focus on men as gendered beings within the available qualitative literature. The findings are consistent with the limited quantitative data, which indicates that grappling with altered gendered identity is a central feature of life for men with SCI. Masculine identity emerges in this review as vulnerable to the impact of SCI, and given the strong links identified between masculinity, rehabilitation and health, as an aspect of experience that warrants more attention than it has received.

    Full Text Available Spinal cord injury is a major trauma, with its short and long term effects and consequences to the patient, his friends and family. Spinal cord injury is addressed in the developed countries with standard trauma care system commencing immediately after injury and continuing to the specialized rehabilitation units. Rehabilitation is important to those with spinal injury for both functional and psychosocial reintegration. It has been an emerging concept in Nepal, which has been evident with the establishment of the various hospitals with rehabilitation units, rehabilitation centres and physical therapy units in different institutions. However, the spinal cord injury rehabilitation setting and scenario is different in Nepal from those in the developed countries since spinal cord injury rehabilitation care has not been adequately incorporated into the health care delivery system nor its importance has been realized within the medical community of Nepal. To name few, lack of human resource for the rehabilitation care, awareness among the medical personnel and general population, adequate scientific research evidence regarding situation of spinal injury and exorbitant health care policy are the important hurdles that has led to the current situation. Hence, it is our responsibility to address these apparent barriers to successful implementation and functioning of rehabilitation so that those with spinal injury would benefit from enhanced quality of life. Keywords: rehabilitation; spinal injury.

    [Purpose] The objective of the study was to compare the incidence, diagnosis, treatment, and prognosis of patients with spinal cord stab injury to those with the more common spinal cord contusion injury. [Subjects] Of patients hospitalized in China Rehabilitation Research Center from 1994 to 2014, 40 of those having a spinal cord stab injury and 50 with spinal cord contusion were selected. [Methods] The data of all patients were analyzed retrospectively. The cases were evaluated by collecting admission and discharge ASIA (American Spinal Injury Association) and ADL (activity of daily living) scores. [Results] After a comprehensive rehabilitation program, ASIA and ADL scores of patients having both spinal cord stab injury and spinal cord contusion significantly increase. However, the increases were noted to be higher in patients having a spinal cord stab injury than those having spinal cord contusion. [Conclusion] Comprehensive rehabilitation is effective both for patients having spinal cord stab injury and those with spinal cord contusion injury. However, the prognosis of patients having spinal cord stab injury is better than that of patients with spinal cord contusion. PMID:26834329

    Although timing for surgical intervention after spinal cord injury remains controversial, there is accumulating evidence suggesting that early surgery may improve neurologic outcomes, particularly with incomplete spinal cord injury, and may reduce non-neurologic complications and health care resource utilization. Moreover, even in patients with complete spinal cord injury, minor improvement in neurologic function can lead to significant changes in quality of life. This article reviews the experimental and clinical data examining surgical timing after spinal cord injury.

    Walking is possible for many patients with a spinal cord injury. Avenues enabling walking include braces, robotics and FES. Among the benefits are improved musculoskeletal and mental health, however unrealistic expectations may lead to negative changes in quality of life. Use rigorous assessment standards to gauge the improvement of walking during the rehabilitation process, but also yearly. Continued walking after discharge may be limited by challenges, such as lack of accessibility in and outside the home, and complications, such as shoulder pain or injuries from falls. It is critical to determine the risks and benefits of walking for each patient.

    Research into transplantation strategies to treat spinal cord injury (SCI) is frequently performed in rodents, but translation of results to clinical patients can be poor and a large mammalian model of severe SCI is needed. The pig has been considered an optimal model species in which to perform preclinical testing, and the Yucatan minipig can be cloned successfully utilizing somatic cell nuclear transfer (SCNT). However, induction of paralysis in pigs poses significant welfare and nursing challenges. The present study was conducted to determine whether Yucatan SCNT clones could be used to develop an SCI animal model for cellular transplantation research. First, we demonstrated that transection of the sacrocaudal spinal cord in Yucatan SCNT clones produces profound, quantifiable neurological deficits restricted to the tail. We then established that neurospheres could be isolated from brain tissue of green fluorescence protein (GFP) transfected SCNT clones. Finally, we confirmed survival of transplanted GFP-expressing neural stem cells in the SCI lesion and their differentiation into glial and neuronal lineages for up to 4 weeks without immunosuppression. We conclude that this model of sacrocaudal SCI in Yucatan SCNT clones represents a powerful research tool to investigate the effect of cellular transplantation on axonal regeneration and functional recovery.

    Recovery from acute spinal cord injury (SCI) is characterized by extensive heterogeneity, resulting in uncertain prognosis. Reliable prediction of recovery in the acute phase benefits patients and their families directly, as well as improves the likelihood of detecting efficacy in clinical trials. This issue of heterogeneity is not unique to SCI. In fields such as traumatic brain injury, Parkinson's disease, and amyotrophic lateral sclerosis, one approach to understand variability in recovery has been to make clinical trial data widely available to the greater research community. We contend that the SCI community should adopt a similar approach in providing open access clinical trial data.

A literature review was conducted using PubMed to identify epidemiological studies reporting data on SCI survivors of the 2005 Kashmir EQ in Pakistan, the Sichuan EQ of 2008 in China and the 2010 Haiti EQ. A follow-up review on the SCI rehabilitation services provided by local and foreign providers in response to these EQs was also performed. Review of the scientific literature revealed the qualitative trends in focused EQ victim epidemiological data, including SCI classification and types of medical complications. Selected EQ country narratives showed that post-disaster SCI rehabilitation services were expanded by adapting local resources with international assistance to manage the significant numbers of SCI survivors. The resulting SCI research was limited. A global disaster research agenda for SCI in EQs in rehabilitation resource-scarce settings is needed to strengthen the evidence base for improvement of clinical management and outcomes for SCI EQ survivors. Expansion of this limited narrative review into a systematic review to identify additional research gaps is a proposed next step. Effective disaster setting data management and research collaborations of foreign and local SCI disability and rehabilitation stakeholders will be required for agenda implementation.

    The morphological and contractile changes of muscles below the level of the lesion after spinal cord injury (SCI) are dramatic. In humans with SCI, a fiber-type transformation away from type I begins 4-7 months post-SCI and reaches a new steady state with predominantly fast glycolytic IIX fibers...... years after the injury. There is a progressive drop in the proportion of slow myosin heavy chain (MHC) isoform fibers and a rise in the proportion of fibers that coexpress both the fast and slow MHC isoforms. The oxidative enzymatic activity starts to decline after the first few months post-SCI. Muscles...... from individuals with chronic SCI show less resistance to fatigue, and the speed-related contractile properties change, becoming faster. These findings are also present in animals. Future studies should longitudinally examine changes in muscles from early SCI until steady state is reached in order...

    Full Text Available Only a few studies have considered changes in brain structures other than sensory and motor cortex after spinal cord injury, although cognitive impairments have been reported in these patients. Spinal cord injury results in chronic brain neuroinflammation with consequent neurodegeneration and cognitive decline in rodents. Regarding the hippocampus, neurogenesis is reduced and reactive gliosis increased. These long-term abnormalities could explain behavioral impairments exhibited in humans patients suffering from spinal cord trauma.

    Full Text Available Waleed Al Taweel, Raouf SeyamDepartment of Urology, King Faisal Specialist Hospital and Research Center, Riyadh, Saudi ArabiaAbstract: Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury.Keywords: neurogenic bladder, spinal cord injury, urodynamics, intestine, intermittent catheterization

    Galactorrhea, a secretion of milk or milk-like products from the breast in the absence of parturition, has been reported to occur in women with spinal cord injuries in association with amenorrhea and hyperprolactinemia. Four cases of galactorrhea in association with spinal cord injury are reported. Galactorrhea developed in four spinal cord injured women who had thoracic paraplegia. The onset of galactorrhea was from one month to five months after injury. Although the onset of galactorrhea may have been related to prescribed medications in all four cases, insufficient data exist to draw conclusions. The three women whose galactorrhea persisted declined treatment and galactorrhea continuing for more than two years in one instance. We conclude that galactorrhea with or without amenorrhea may develop after a spinal cord injury and that spinal cord injured women may have an enhanced sensitivity to medication-induced galactorrhea.

  9. Neuroprotection and its molecular mechanism following spinal cord injury

    2012-01-01

    Acute spinal cord injury initiates a complex cascade of molecular events termed 'secondary injury', which leads to progressive degeneration ranging from early neuronal apoptosis at the lesion site to delayed degeneration of intact white matter tracts, and, ultimately, expansion of the initial injury. These secondary injury processes include, but are not limited to, inflammation, free radical-induced cell death, glutamate excitotoxicity, phospholipase A2 activation, and induction of extrinsic and intrinsic apoptotic pathways, which are important targets in developing neuroprotective strategies for treatment of spinal cord injury. Recently, a number of studies have shown promising results on neuroprotection and recovery of function in rodent models of spinal cord injury using treatments that target secondary injury processes including inflammation, phospholipase A2 activation, and manipulation of the PTEN-Akt/mTOR signaling pathway. The present review outlines our ongoing research on the molecular mechanisms of neuroprotection in experimental spinal cord injury and briefly summarizes our earlier findings on the therapeutic potential of pharmacological treatments in spinal cord injury.

    Spinal cord injury results in significant mortality and morbidity, lifestyle changes, and difficult rehabilitation. Treatment of spinal cord injury is challenging because the spinal cord is both complex to treat acutely and difficult to regenerate. Nanomaterials can be used to provide effective treatments; their unique properties can facilitate drug delivery to the injury site, enact as neuroprotective agents, or provide platforms to stimulate regrowth of damaged tissues. We review recent uses of nanomaterials including nanowires, micelles, nanoparticles, liposomes, and carbon-based nanomaterials for neuroprotection in the acute phase. We also review the design and neural regenerative application of electrospun scaffolds, conduits, and self-assembling peptide scaffolds.

    Objective To confirm the role played by apoptosis in spinal cord injury. Methods 36 rats models of spinal cord injury were made by Allen method. Histological examinations using HE staining and in situ end-labeling were used to observe apoptosis in spinal cord tissues from 1h to 21d after injury. Results HE staining sections showed hemorrhage and necrosis, neuronal degeneration and gliai cell proliferation. In situ end-labeling sections showed the appearance of apoptosis in both gray and white matter as well as in both central and surrounding region. The number of apoptotic cells increased from 12h after injury, increased to the peak at 4d and declined to normal at 21d. Conclu sion The results suggest that apoptosis, especially glial apoptosis, plays a role in the pathogenesis of spinal cord in jury.

    Sex is a legitimate and fundamental need in humans. Substantial changes to both the autonomic and somatic nervous system occur after spinal cord injury, and result in altered sexual function and fertility potential. This chapter provides a clinical overview of the main sexual and reproductive concerns and priorities men and women face after spinal cord injury. Besides genital functioning, other autonomic functions affect sexuality, such as bladder and bowel function, cardiovascular control and temperature regulation. These interlinked autonomic functions are presented in their impact on sexuality. The mind-body interaction and spinal feedback loops are discussed. It is proposed that human sexuality after spinal cord injury can be a model for investigating integrated autonomic function. Recent research on the measurement of cardiovascular parameters during vibrostimulation and ejaculation demonstrates the discordance between objective and subjective signs of autonomic dysreflexia. It is hoped that health care professionals and researchers will become motivated to attend to the unmet sexual health care needs of this population.

    To review the basic principles and techniques of transcranial magnetic stimulation (TMS) and provide information and evidence regarding its applications in spinal cord injury clinical rehabilitation. A review of the available current and historical literature regarding TMS was conducted, and a discussion of its potential use in spinal cord injury rehabilitation is presented. TMS provides reliable information about the functional integrity and conduction properties of the corticospinal tracts and motor control in the diagnostic and prognostic assessment of various neurological disorders. It allows one to follow the evolution of motor control and to evaluate the effects of different therapeutic procedures. Motor-evoked potentials can be useful in follow-up evaluation of motor function during treatment and rehabilitation, specifically in patients with spinal cord injury and stroke. Although studies regarding somatomotor functional recovery after spinal cord injury have shown promise, more trials are required to provide strong and substantial evidence. TMS is a promising noninvasive tool for the treatment of spasticity, neuropathic pain, and somatomotor deficit after spinal cord injury. Further investigation is needed to demonstrate whether different protocols and applications of stimulation, as well as alternative cortical sites of stimulation, may induce more pronounced and beneficial clinical effects.

    2013-11-01

    Full Text Available Spinal cord injury is a major health burden and currently there is no effective medical intervention. Research performed over the last decade revealed that cells surrounding the central canal of the adult spinal cord and forming the ependymal layer acquire stem cell properties either in vitro or in response to injury. Following spinal cord injury activated ependymal cells generate progeny cells which migrate to the injury site but fail to produce the appropriate type of cells in sufficient number to limit the damage, rendering this physiological response mainly ineffective. Research is now focusing on the manipulation of ependymal cells to produce cells of the oligodendrocyte lineage which are primarily lost in such a situation leading to secondary neuronal degeneration. Thus, there is a need for a more focused approach to understand the molecular properties of adult ependymal cells in greater detail and develop effective strategies for guiding their response during spinal cord injury.

    Full Text Available Spinal cord injury (SCI is a complex disease process that involves both primary and secondary mechanisms of injury and can leave patients with devastating functional impairment as well as psychological debilitation. While no curative treatment is available for spinal cord injury, current therapeutic approaches focus on reducing the secondary injury that follows SCI. Hyperbaric oxygen (HBO therapy has shown promising neuroprotective effects in several experimental studies, but the limited number of clinical reports have shown mixed findings. This review will provide an overview of the potential mechanisms by which HBO therapy may exert neuroprotection, provide a summary of the clinical application of HBO therapy in patients with SCI, and discuss avenues for future studies.

    Disability following traumatic spine injury often requires assessment for judicial reasons. To determine the optimum time to carry out a medico-legal evaluation. Retrospective study (1995-2000) of patients with traumatic spine injury with a follow-up of five years. The American Spinal Injury Association (ASIA) scale was used to determine level and extent of the injury. Statistical analysis by SPSS 11.0. 173 injuries were analyzed (39.3% ASIA A; 15.6% ASIA B; 29.47% ASIA C; 15.6% ASIA D). Neurological improvement was detected in 35.83%, more frequently in incomplete injuries. ASIA A injuries remained mainly complete from admission to discharge and in no case reached functional levels. Only a third of ASIA B patients showed improvement, of whom 33.3% were functional. Improvement in ASIA C patients was 76.4%, these and all ASIA D patients were functional on discharge. The condition a year after the injury remained unchanged in all cases, regardless of the extent of injury. Patients who showed improvement did so early on, mainly during hospitalization. The optimum time for evaluation of spinal cord injury for medicolegal purposes is at one year after the injury. In cases of complete injury, evaluation can be carried out on discharge with no need to wait for one year.

  10. Imatinib enhances functional outcome after spinal cord injury.

    Directory of Open Access Journals (Sweden)

    Mathew B Abrams

    Full Text Available We investigated whether imatinib (Gleevec®, Novartis, a tyrosine kinase inhibitor, could improve functional outcome in experimental spinal cord injury. Rats subjected to contusion spinal cord injury were treated orally with imatinib for 5 days beginning 30 minutes after injury. We found that imatinib significantly enhanced blood-spinal cord-barrier integrity, hindlimb locomotor function, sensorimotor integration, and bladder function, as well as attenuated astrogliosis and deposition of chondroitin sulfate proteoglycans, and increased tissue preservation. These improvements were associated with enhanced vascular integrity and reduced inflammation. Our results show that imatinib improves recovery in spinal cord injury by preserving axons and other spinal cord tissue components. The rapid time course of these beneficial effects suggests that the effects of imatinib are neuroprotective rather than neurorestorative. The positive effects on experimental spinal cord injury, obtained by oral delivery of a clinically used drug, makes imatinib an interesting candidate drug for clinical trials in spinal cord injury.

    Traumatic spinal cord injury (SCI) is a devastating neurological condition characterized by a constellation of symptoms including paralysis, paraesthesia, pain, cardiovascular, bladder, bowel and sexual dysfunction. Current treatment for SCI involves acute resuscitation, aggressive rehabilitation and symptomatic treatment for complications. Despite the progress in scientific understanding, regenerative therapies are lacking. In this review, we outline the current state and future potential of invasive and non-invasive neuromodulation strategies including deep brain stimulation (DBS), spinal cord stimulation (SCS), motor cortex stimulation (MCS), transcutaneous direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) in the context of SCI. We consider the ability of these therapies to address pain, sensorimotor symptoms and autonomic dysregulation associated with SCI. In addition to the potential to make important contributions to SCI treatment, neuromodulation has the added ability to contribute to our understanding of spinal cord neurobiology and the pathophysiology of SCI.

  13. Gene therapy approaches for spinal cord injury

    Science.gov (United States)

    Bright, Corinne

    As the biomedical engineering field expands, combination technologies are demonstrating enormous potential for treating human disease. In particular, intersections between the rapidly developing fields of gene therapy and tissue engineering hold promise to achieve tissue regeneration. Nonviral gene therapy uses plasmid DNA to deliver therapeutic proteins in vivo for extended periods of time. Tissue engineering employs biomedical materials, such as polymers, to support the regrowth of injured tissue. In this thesis, a combination strategy to deliver genes and drugs in a polymeric scaffold was applied to a spinal cord injury model. In order to develop a platform technology to treat spinal cord injury, several nonviral gene delivery systems and polymeric scaffolds were evaluated in vitro and in vivo. Nonviral vector trafficking was evaluated in primary neuronal culture to develop an understanding of the barriers to gene transfer in neurons and their supporting glia. Although the most efficient gene carrier in vitro differed from the optimal gene carrier in vivo, confocal and electron microscopy of these nonviral vectors provided insights into the interaction of these vectors with the nucleus. A novel pathway for delivering nanoparticles into the nuclei of neurons and Schwann cells via vesicle trafficking was observed in this study. Reporter gene expression levels were evaluated after direct and remote delivery to the spinal cord, and the optimal nonviral vector, dose, and delivery strategy were applied to deliver the gene encoding the basic fibroblast growth factor (bFGF) to the spinal cord. An injectable and biocompatible gel, composed of the amphiphillic polymer poly(ethylene glycol)-poly(epsilon-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG) was evaluated as a drug and gene delivery system in vitro, and combined with the optimized nonviral gene delivery system to treat spinal cord injury.

    The ability of diffusion tensor imaging (DTI) to complement conventional MR imaging by diagnosing subtle injuries to the spinal cord is a subject of intense research. We attempted to study change in the DTI indices, namely fractional anisotropy (FA) and mean diffusivity (MD) after traumatic cervical spinal cord injury and compared these with corresponding data from a control group of individuals with no injury. The correlation of these quantitative indices to the neurological profile of the patients was assessed. 20 cases of acute cervical trauma and 30 age and sex matched healthy controls were enrolled. Scoring of extent of clinical severity was done based on the Frankel grading system. MRI was performed on a 3T system. Following the qualitative tractographic evaluation of white matter tracts, quantitative datametrics were calculated. In patients, the Mean FA value at the level of injury (0.43+/-0.08) was less than in controls (0.62+/-0.06), which was statistically significant (p value injury (1.30+/-0.24) in cases was higher than in controls (1.07+/-0.12, p value injury (r value=0.86). Negative correlation was found between clinical grade and Mean MD at the level of injury (r value=-0.38) which was however statistically not significant. Quantitative DTI indices are a useful parameter for detection of spinal cord injury. FA value was significantly decreased while MD value was significantly increased at the level of injury in cases as compared to controls. Further, FA showed significant correlation with clinical grade. DTI could thus serve as a reliable objective imaging tool for assessment of white matter integrity and prognostication of functional outcome. Copyright © 2017 Elsevier Ltd. All rights reserved.

  16. Restoring function after spinal cord injury: towards clinical translation of experimental strategies.

    Science.gov (United States)

    Ramer, Leanne M; Ramer, Matt S; Bradbury, Elizabeth J

    2014-12-01

    Spinal cord injury is currently incurable and treatment is limited to minimising secondary complications and maximising residual function by rehabilitation. Improved understanding of the pathophysiology of spinal cord injury and the factors that prevent nerve and tissue repair has fuelled a move towards more ambitious experimental treatments aimed at promoting neuroprotection, axonal regeneration, and neuroplasticity. By necessity, these new options are more invasive. However, in view of recent advances in spinal cord injury research and demand from patients, clinicians, and the scientific community to push promising experimental treatments to the clinic, momentum and optimism exist for the translation of candidate experimental treatments to clinical spinal cord injury. The ability to rescue, reactivate, and rewire spinal systems to restore function after spinal cord injury might soon be within reach. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Spinal cord injury often results in permanent functional impairment. Neural stem cells present in the adult spinal cord can be expanded in vitro and improve recovery when transplanted to the injured spinal cord, demonstrating the presence of cells that can promote regeneration but that normally fail to do so efficiently. Using genetic fate mapping, we show that close to all in vitro neural stem cell potential in the adult spinal cord resides within the population of ependymal cells lining the central canal. These cells are recruited by spinal cord injury and produce not only scar-forming glial cells, but also, to a lesser degree, oligodendrocytes. Modulating the fate of ependymal progeny after spinal cord injury may offer an alternative to cell transplantation for cell replacement therapies in spinal cord injury.

    A spinal cord injury refers to an injury to the spinal cord that is caused by a trauma instead of diseases. Spinal cord injury includes a primary mechanical injury and a much more complex secondary injury pro-cess involving inlfammation, oxidation, excitotoxicity, and cell death. During the secondary injury, many signal pathways are activated and play important roles in mediating the pathogenesis of spinal cord injury. Among them, the RhoA/Rho kinase pathway plays a particular role in mediating spinal degeneration and regeneration. In this review, we will discuss the role and mechanism of RhoA/Rho kinase-mediated spinal cord pathogenesis, as well as the potential of targeting RhoA/Rho kinase as a strategy for promoting both neuroprotection and axonal regeneration.

  20. Early elective colostomy following spinal cord injury.

    Science.gov (United States)

    Boucher, Michelle

    Elective colostomy is an accepted method of bowel management for patients who have had a spinal cord injury (SCI). Approximately 2.4% of patients with SCI have a colostomy, and traditionally it is performed as a last resort several years after injury, and only if bowel complications persist when all other methods have failed. This is despite evidence that patients find a colostomy easier to manage and frequently report wishing it had been performed earlier. It was noticed in the author's spinal unit that increasing numbers of patients were requesting colostomy formation during inpatient rehabilitation following SCI. No supporting literature was found for this; it appears to be an emerging and untested practice. This article explores colostomy formation as a method of bowel management in patients with SCI, considers the optimal time for colostomy formation after injury and examines issues for health professionals.

    Individuals with spinal cord injury (SCI) commonly complain about difficulty in sleeping. Although various sleep disordered breathing definitions and indices are used that make comparisons between studies difficult, it seems evident that the frequency of sleep disorders is higher in individuals...... with SCI, especially with regard to obstructive sleep apnea. In addition, there is a correlation between the incidence of sleep disturbances and the spinal cord level injured, age, body mass index, neck circumference, abdominal girth, and use of sedating medications. Regulation of respiration is dependent...... on wakefulness and sleep. Thus, it is important to be aware of basic mechanisms in the regulation and control of sleep and awake states. Supine position decreases the vital capacity in tetraplegic individuals, and diminished responsiveness to Pa(CO)(2) may further decrease ventilatory reserve. There also may...

    Abstract The long-term impact of spinal cord injury (SCI) on the health care system imposes a need for greater efficiency in the use of resources and the management of care. The Access to Care and Timing (ACT) project was developed to model the health care delivery system in Canada for patients with traumatic SCI. Techniques from Operations Research, such as simulation modeling, were used to predict the impact of best practices and policy initiatives on outcomes related to both the system and patients. These methods have been used to solve similar problems in business and engineering and may offer a unique solution to the complexities encountered in SCI care delivery. Findings from various simulated scenarios, from the patients' point of injury to community re-integration, can be used to inform decisions on optimizing practice across the care continuum. This article describes specifically the methodology and implications of producing such simulations for the care of traumatic SCI in Canada. Future publications will report on specific practices pertaining to the access to specialized services and the timing of interventions evaluated using the ACT model. Results from this type of research will provide the evidence required to support clinical decision making, inform standards of care, and provide an opportunity to engage policymakers. PMID:22800432

  6. Rat models of spinal cord injury: from pathology to potential therapies

    2016-01-01

    ABSTRACT A long-standing goal of spinal cord injury research is to develop effective spinal cord repair strategies for the clinic. Rat models of spinal cord injury provide an important mammalian model in which to evaluate treatment strategies and to understand the pathological basis of spinal cord injuries. These models have facilitated the development of robust tests for assessing the recovery of locomotor and sensory functions. Rat models have also allowed us to understand how neuronal circuitry changes following spinal cord injury and how recovery could be promoted by enhancing spontaneous regenerative mechanisms and by counteracting intrinsic inhibitory factors. Rat studies have also revealed possible routes to rescuing circuitry and cells in the acute stage of injury. Spatiotemporal and functional studies in these models highlight the therapeutic potential of manipulating inflammation, scarring and myelination. In addition, potential replacement therapies for spinal cord injury, including grafts and bridges, stem primarily from rat studies. Here, we discuss advantages and disadvantages of rat experimental spinal cord injury models and summarize knowledge gained from these models. We also discuss how an emerging understanding of different forms of injury, their pathology and degree of recovery has inspired numerous treatment strategies, some of which have led to clinical trials.

    Spinal cord injury (SCI) patients should be assessed for a co-occurring traumatic brain injury (TBI) on admission to a rehabilitation program. Incidence of a dual diagnosis may approach 60% with certain risk factors. Diagnosis of mild-moderate severity TBIs may be missed during acute care hospitalizations of SCI. Neuropsychological symptoms of a missed TBI diagnosis may be perceived during rehabilitation as noncompliance, inability to learn, maladaptive reactions to SCI, and poor motivation. There are life-threatening and quality-of-life-threatening complications of TBI that also may be missed if a dual diagnosis is not made.

    Regeneration in the central nervous system (CNS) of adult mammalian after traumatic injury is limited, which often causes permanent functional motor and sensory loss. After spinal cord injury (SCI), the lack of regeneration is mainly attributed to the presence of a hostile microenvironment, glial scarring, and cavitation. Besides, inflammation has also been proved to play a crucial role in secondary degeneration following SCI. The more prominent treatment strategies in experimental models focus mainly on drugs and cell therapies, however, only a few strategies applied in clinical studies and therapies still have only limited effects on the repair of SCI. Recently, the interests in immunotherapy strategies for CNS are increasing in number and breadth. Immunotherapy strategies have made good progresses in treating many CNS degenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease (PD), stroke, and multiple sclerosis (MS). However, the strategies begin to be considered to the treatment of SCI and other neurological disorders in recent years. Besides anti-inflamatory therapy, immunization with protein vaccines and DNA vaccines has emerged as a novel therapy strategy because of the simplicity of preparation and application. An inflammatory response followed by spinal cord injury, and is controled by specific signaling molecules, such as some cytokines playing a crucial role. As a result, appropriate immunoregulation, the expression of pro-inflammatory cytokines and anti-inflammatory cytokines may be an effective therapy strategy for earlier injury of spinal cord. In addition, myelinassociated inhibitors (MAIs) in the injured spinal cord, such as Nogo, myelin-associated glycoprotein (MAG) and oligodendrocyte- myelin glycoprotein (OMgp) are known to prevent axonal regeneration through their co-receptors, and to trigger demyelinating autoimmunity through T cell-mediated harmful autoimmune response. The antagonism of the MAIs through vaccinating with

    The injured spinal cord does not heal properly. In contrast, tissue repair and functional recovery occur after skin or muscle injuries. The reason for this dichotomy in wound repair is unclear but inflammation, and specifically macrophage activation, likely plays a key role. Macrophages have the ability to promote the repair of injured tissue by regulating transitions through different phase of the healing response. In the current review we compare and contrast the healing and inflammatory responses between spinal cord injuries and tissues that undergo complete wound resolution. Through this comparison, we identify key macrophage phenotypes that are inaptly triggered or absent after spinal cord injury and discuss spinal cord stimuli that contribute to this maladaptive response. Sequential activation of classic, pro-inflammatory, M1 macrophages and alternatively activated, M2a, M2b, and M2c macrophages occurs during normal healing and facilitates transitions through the inflammatory, proliferative, and remodeling phases of repair. In contrast, in the injured spinal cord, pro-inflammatory macrophages potentiate a prolonged inflammatory phase and remodeling is not properly initiated. The desynchronized macrophage activation after spinal cord injury is reminiscent of the inflammation present in chronic, non-healing wounds. By refining the role macrophages play in spinal cord injury repair we bring to light important areas for future neuroinflammation and neurotrauma research.

    The history of spinal cord injuries starts with the ancient Egyptian medical papyrus known as the Edwin Smith Surgical Papyrus. The papyrus written about 2500 B.C.by the physician and architect of the Sakkara pyramids Imhotep, describes "crushed vertebra in his neck" as well as symptoms of neurological deterioration. An ailment not to be treated was the massage to the patients at that time. This fatalistic attitude remained until the end of World War II when the first rehabilitation centre focused on the rehabilitation of spinal cord injured patients was opened. Our knowledge of the pathophysiological processes, both the primary as well as the secondary, has increased tremendously. However, all this knowledge has only led to improved medical care but not to any therapeutic method to restore, even partially, the neurological function. Neuroprotection is defined as measures to counteract secondary injury mechanisms and/or limit the extent of damage caused by self-destructive cellular and tissue processes. The co-existence of several distinctly different injury mechanisms after trauma has provided opportunities to explore a large number of potentially neuroprotective agents in animal experiments such as methylprednisolone sodium succinate. The results of this research have been very discouraging and pharmacological neuroprotection for patients with spinal cord injury has fallen short of the expectations created by the extensive research and promising observations in animal experiments. The focus of research has now, instead, been transformed to the field of neural regeneration. This field includes the discovery of regenerating obstacles in the nerve cell and/or environmental factors but also various regeneration strategies such as bridging the gap at the site of injury as well as transplantation of foetal tissue and stem cells. The purpose of this review is to highlight selected experimental and clinical studies that form the basis for undertaking future challenges in

    Since loss of of oligodendrocytes and consequent demyelination of spared axons severely impair the functional recovery of injured spinal cord,it is reasonably expected that the reduction of oligodendroglial death and enhanced remyelination of demyelinated axons will have a therapeutic potential to treat spinal cord injury.Amelioration of axonal myelination in the injured spinal cord is valuable for recovery of the neural function of incompletely injured patients.Here,this article presents an overview about the pathophysiology and mechanism of axonal demyelination in spinal cord injury and discusses its therapeutic significance in the treatment of spinal cord injury.Moreover,it further introduces the recent strategies to improve the axonal myeliantion to facilitate functional recovery of spinal cord injury.

    Objective To review the recent studies about human umbilical cord mesenchymal stem cells (hUCMSCs) and advances in the treatment of spinal cord injury, Data sources Published articles (1983-2007) about hUCMSCs and spinal cord injury were selected using Medline. Study selection Articles selected were relevant to development of mesenchymal stem cells (MSCs) for transplantation in spinal cord injury therapy. Of 258 originally identifiied arises 51 were selected that specifically addressed the stated purpose. Results Recent work has revealed that hUCMSCs share most of the characteristics with MSCs derived from bone marrow and are more appropriate to transplantation for cell based therapies. Conclusions Human umbilical cord could be regarded as a source of MSCs for experimental and clinical needs. In addition, as a peculiar source of stem cells, hUCMSCs may play an important role in the treatment of spinal cord injury.

    Damage from spinal cord injury (SCI) may be complicated by concomitant hemodynamic alterations within hours to months of the initial insult. Neurogenic shock, symptomatic bradycardia, autonomic dysreflexia, and orthostatic hypotension are specific conditions occurring commonly with SCI. Early recognition and appropriate management of each disorder may minimize secondary injury to the cord, avert systemic complications, and help alleviate patient discomfort.

  4. Role of taurine in spinal cord injury.

    Science.gov (United States)

    Gupta, R C; Seki, Y; Yosida, J

    2006-08-01

    Taurine is a sulfur amino acid. It is found endogenously in human and several others tissues. It is significantly in high concentration in mammals. Human body contains about 0.1% of body weight as taurine. It has a number of physiological and pharmacological actions. It is also used in the therapy of important organs dysfunctions. In spinal cord it has inhibitory effects; like antiepileptic and anti-nociceptive. Taurine also inhibits substance p induced biting and scratching behavior. In spinal cord injury elevated level of taurine has been observed. Higher level of taurine has been also recorded in SCI therapy using, known clinical agent methyl prednisolone (MP). The increased taurine concentration seems to be involved in protection and regeneration of tissues following injury. In SCI along with physical injury secondary activities also takes place which are complex in nature. Secondary activity includes vascular events and activation of neutrophils, resulting endothelial damage. Activated neutrophils; release a variety of inflammatory mediators such as myeloperoxidase (MPO), reactive oxygen species (ROS), and some others. It is believed that taurine exert its protective action through scavenging of ROS and down regulating several other inflammatory mediators like tumor necrosis factors (TNFalpha). The inside of mechanism reveals toxic substance HOCl is produced by MPO is converted to less toxic substances through scavenging action of taurine. Amino acid therapy has its own limitations and to over come such situation there is a need to develop small, simple lipophilic analogs of taurine. Use of taurine analogs has provided better results; for example, N- chloro taurine (NCT) which is a taurine derivative has exhibited therapeutic advances over taurine. Taurine and its analogs with sound experimental and clinical support may constitute a new class of therapeutic agents for SCI., and perhaps this review may provide enough material to think of this.

    The aim of this article is to analyze the vascular dysfunctions occurring after spinal cord injury (SCI). Vascular dysfunctions are common complications of SCI. Cardiovascular disturbances are the leading causes of morbidity and mortality in both acute and chronic stages of SCI. Neuroanatomy and physiology of autonomic nervous system, sympathetic and parasympathetic, is reviewed. SCI implies disruption of descendent pathways from central centers to spinal sympathetic neurons, originating in intermediolateral nuclei of T1-L2 cord segments. Loss of supraspinal control over sympathetic nervous system results in reduced overall sympathetic activity below the level of injury and unopposed parasympathetic outflow through intact vagal nerve. SCI associates significant vascular dysfunction. Spinal shock occurs during the acute phase following SCI and it is a transitory suspension of function and reflexes below the level of the injury. Neurogenic shock, part of spinal shock, consists of severe arterial hypotension and bradycardia. Autonomic dysreflexia appears during the chronic phase, after spinal shock resolution, and it is a life-threatening syndrome of massive imbalanced reflex sympathetic discharge occurring in patients with SCI above the splanchnic sympathetic outflow (T5-T6). Arterial hypotension with orthostatic hypotension occurs in both acute and chronic phases. The etiology is multifactorial. We described a few factors influencing the orthostatic hypotension occurrence in SCI: sympathetic nervous system dysfunction, low plasma catecholamine levels, rennin-angiotensin-aldosterone activity, peripheral alpha-adrenoceptor hyperresponsiveness, impaired function of baroreceptors, hyponatremia and low plasmatic volume, cardiovascular deconditioning, morphologic changes in sympathetic neurons, plasticity within spinal circuits, and motor deficit leading to loss of skeletal muscle pumping activity. Additional associated cardiovascular concerns in SCI, such as deep vein

    To synthesize the qualitative research evidence that explored how survivors of adult spinal cord injury experience and make sense of resilience. Spinal cord injury is often a sudden and unexpected life-changing event requiring complex and long-term rehabilitation. The development of resilience is essential in determining how spinal cord injury survivors negotiate this injury and rehabilitation. A qualitative systematic review and thematic synthesis of the research evidence. CINAHL, PubMed, Embase, Scopus and PsycINFO were searched, no restriction dates were used. Methodological quality was assessed using the Critical Appraisal Skills Programme checklist. Thematic synthesis focused on how survivors of adult spinal cord injury experience and make sense of resilience. Six qualitative research articles reported the experiences of 84 spinal cord injury survivors. Themes identified were: uncertainty and regaining independence; prior experiences of resilience; adopting resilient thinking; and strengthening resilience through supports. Recovery and rehabilitation following spinal cord survivors is influenced by the individual's capacity for resilience. Resilience may be influenced by previous life experiences and enhanced by supportive nursing staff encouraging self-efficacy. Survivors identified the need for active involvement in decision-making about their care to enable a sense of regaining control of their lives. This has the potential to have a significant impact on their self-efficacy and in turn health outcomes. © 2017 John Wiley & Sons Ltd.

    Spinal cord injury can be defined as a loss of communication between the brain and the body due to disrupted pathways within the spinal cord. Although many promising molecular strategies have emerged to reduce secondary injury and promote axonal regrowth, there is still no effective cure, and recovery of function remains limited. Functional electrical stimulation (FES) represents a strategy developed to restore motor function without the need for regenerating severed spinal pathways. Despite its technological success, however, FES has not been widely integrated into the lives of spinal cord injury survivors. In this review, we briefly discuss the limitations of existing FES technologies. Additionally, we discuss how optogenetics, a rapidly evolving technique used primarily to investigate select neuronal populations within the brain, may eventually be used to replace FES as a form of therapy for functional restoration after spinal cord injury.

    LIN28, an RNA-binding protein, is known to be involved in the regulation of many cellular processes, such as embryonic stem cell proliferation, cell fate succession, developmental timing, and oncogenesis. However, its expression and function in central nervous system still unclear. In this study, we performed an acute spinal cord contusion injury (SCI) model in adult rats and investigated the dynamic changes of LIN28 expression in spinal cord. Western blot and immunohistochemistry analysis revealed that LIN28 was present in normal spinal cord. It gradually increased, reached a peak at 3 day, and then nearly declined to the basal level at 14 days after SCI. Double immunofluorescence staining showed that LIN28 immunoreactivity was found in neurons, astrocytes and a handful of microglia. Interestingly, LIN28 expression was increased predominantly in astrocytes but not in neurons. Moreover, the colocalization of LIN28 and proliferating cell nuclear antigen was detected after injury. Western blot showed that LIN28 participated in lipopolysaccharide (LPS) induced astrocytes inflammatory responses by NF-κB signaling pathway. These results suggested that LIN28 may be involved in the pathologic process of SCI, and further research is needed to have a good understanding of its function and mechanism.

  13. Rugby union injuries to the cervical spine and spinal cord.

    2002-01-01

    Injuries to the cervical spine are among the most serious injuries occurring as a result of participation in rugby. Outcomes of such injuries range from complete recovery to death, depending on the degree of spinal cord damage sustained. Much information has been gained regarding the mechanisms and frequency of such injuries, from case reports and case series studies. The most commonly reported mechanism of injury has been hyperflexion of the cervical spine, resulting in fracture dislocation of C4-C5 or C5-C6. Tracking both the trends of incidence of spinal injuries, and the effectiveness of injury prevention initiatives has proved difficult because of a lack of properly conducted epidemiological studies. Within the constraints of the research published to date, it appears that hookers and props have been at disproportionate risk of cervical spine injury, predominantly because of injuries sustained during scrummaging. While the scrum was the phase of play most commonly associated with spinal injuries throughout the 1980s in most rugby playing countries, there has been a trend through the 1990s of an increasing proportion of spinal injuries occurring in the tackle situation. The majority of injuries have occurred early in the season, when grounds tend to be harder, and players are lacking both practice and physical conditioning for the physical contact phases of the sport. A number of injury prevention measures have been launched, including changes to the laws of the game regarding scrummaging, and education programmes aimed at enforcing safe techniques and eliminating illegal play. Calls for case-registers and effective epidemiological studies have been made by researchers and physicians in most countries where rugby is widespread, but it appears to be only recently that definite steps have been made towards this goal. Well-designed epidemiological studies will be able to provide more accurate information about potential risk factors for injury such as age, grade

    2016-09-01

    Full Text Available Line Jacques, Michael Safaee Department of Neurological Surgery, University of California, San Francisco, San Francisco, CA, USA Abstract: This paper is a review of some of the current research focused on using existing epidural spinal cord stimulation technologies in establishing the effectiveness in the recovery of independent standing, ambulation, or intentional movement of spinal cord injury patients. From a clinician’s perspective, the results have been intriguing, from a restorative perspective they are promising, and from a patient’s perspective they are hopeful. The outcomes, although still in the experimental phase, show some proof of theory and support further research. From a high volume university based clinician’s perspective, the resources needed to integrate this type of restorative care into a busy clinical practice are highly challenging without a well-structured and resource rich institutional restorative program. Patient selection is profoundly critical due to the extraordinary resources needed, and the level of motivation required to participate in such an intense and arduous rehabilitation process. Establishing an algorithmic approach to patient selection and treatment will be paramount to effectively utilize scarce resources and optimize outcomes. Further research is warranted, and the development of dedicated technological hardware and software for this therapeutic treatment versus using traditional spinal cord stimulation devices may yield more robust and efficacious outcomes.

    Magnetic resonance imaging (MRI) provides a noninvasive and very important method of investigating spinal-cord injuries. By means of MRI we examined 36 patients with spinal injuries, 34 of them in the acute stage. 19 cases had complete spinal-cord injury with paraplegia, while 17 cases had incomplete spinal-cord injury. MRI showed the injured spinal-cord in the acute stage to be partially swollen, with a high signal intensity in the T[sub 2]-weighted images. In the chronic stage, the injured cord may show atrophic changes with a post-traumatic cavity or myelomalacia, which appears as a high-signal-intensity lesion in the T[sub 2]-weighted images and as a low-signal intensity in the T[sub 1]-weighted images. The cases with complete spinal injuries showed a high signal intensity at the wide level, and these prognoses were poor. The cases with incomplete injuries showed normal findings or a high-signal-intensity spot. In the Gd-DTPA enhanced images, the injured cords were enhanced very well in the subchronic stage. MRI is thus found to be useful in the diagnosis of spinal injuries; it also demonstrates a potential for predicting the neurological prognosis. (author).

    Magnetic resonance (MR) images of a total of 195 patients with cervical (125) or thoracic (70) spinal cord injury were reviewed. The imaging studies of the spinal cord lesions were correlated with clinical manifestations. Sequential MR imaging revealed hypointensity on T1-weighted images (T1WI) and hyperintensity on T2-weighted images (T2WI) in all patients, except for five patients showing no signal changes and two showing isointensity, suggesting gliosis, myelomalacia, and syringomyelia. Spinal cord lesions were classified into four types: small lesions, large lesions, complete transverse, and longitudinal rupture. These lesions were well correlated with the severity of injury and paralysis. Complete paralysis was frequently associated with enlarged, complete transverse for cervical spinal cord injury, and longitudinal ruptured or thinned complete transverse for thoracic spinal cord injury. The height of paralysis was well in agreement with that of lesions. For incomplete paralysis, localized lesions were seen within the spinal cord, coinciding with the paralysis or severity. Traumatic syringomyelia was seen in 17 patients (8.7%)-- for the cervical site (10 patients, 8%) and the thoracic site (7 patients, 10%). When homogeneous and marginally clear hypointensity is shown on T1-weighted images and vacuolated hyperintensity is shown on T2-weighted images, in addition to lesions spreading two or more cords or 1.5 or more cords above the nervous root level of paralysis, traumatic syringomyelia is strongly suspected, requiring the follow up observation.

  20. Maladaptive spinal plasticity opposes spinal learning and recovery in spinal cord injury

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI. Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. The mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain pathways in the spinal cord may emerge with certain patterns of activity, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after spinal cord injury. We review these basic phenomena, discuss the cellular and molecular mechanisms, and discuss implications of these findings for improved rehabilitative therapies after spinal cord injury.

    Clinical studies have shown that hyperbaric oxygen therapy improves motor function in patients with spinal cord injury. In the present study, we explored the mechanisms associated with the recovery of neurological function after hyperbaric oxygen therapy in a rat model of spinal cord injury. We established an acute spinal cord injury model using a modiifcation of the free-falling object method, and treated the animals with oxygen at 0.2 MPa for 45 minutes, 4 hours after injury. The treatment was administered four times per day, for 3 days. Compared with model rats that did not receive the treatment, rats exposed to hyperbaric oxygen had fewer apoptotic cells in spinal cord tissue, lower expression levels of aquaporin 4/9 mRNA and protein, and more NF-200 positive nerve ifbers. Furthermore, they had smaller spinal cord cavities, rapid recovery of somatosensory and motor evoked potentials, and notably better recovery of hindlimb motor function than model rats. Our ifndings indicate that hyperbaric oxygen therapy reduces apop-tosis, downregulates aquaporin 4/9 mRNA and protein expression in injured spinal cord tissue, improves the local microenvironment for nerve regeneration, and protects and repairs the spinal cord after injury.

    Adult zebrafish has a remarkable capability to recover from spinal cord injury,providing an excellent model for studying neuroregeneration.Here we list equipment and reagents,and give a detailed protocol for complete transection of the adult zebrafish spinal cord.In this protocol,potential problems and their solutions are described so that the zebrafish spinal cord injury model can be more easily and reproducibly performed.In addition,two assessments are introduced to monitor the success of the surgery and functional recovery:one test to assess free swimming capability and the other test to assess extent of neuroregeneration by in vivo anterograde axonal tracing.In the swimming behavior test,successful complete spinal cord transection is monitored by the inability of zebrafish to swim freely for 1 week after spinal cord injury,followed by the gradual reacquisition of full locomotor ability within 6 weeks after injury.As a morphometric correlate,anterograde axonal tracing allows the investigator to monitor the ability of regenerated axons to cross the lesion site and increasingly extend into the gray and white matter with time after injury,confirming functional recovery.This zebrafish model provides a paradigm for recovery from spinal cord injury,enabling the identification of pathways and components of neuroregeneration.

    2015-01-01

    Neurological injury, such as spinal cord injury, has a secondary injury associated with it. The secondary injury results from the biological cascade after the primary injury and affects previous uninjured, healthy tissue. Therefore, the mitigation of such a cascade would benefit patients suffering a primary injury and allow the body to recover more quickly. Unfortunately, the delivery of effective therapeutics is quite limited. Due to the inefficient delivery of therapeutic drugs, nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help treat disease by delivering drugs to specific tissues, enhancing detection methods, or a mixture of both. Incorporating nanomedicine into the treatment of neuronal injury and disease would likely push nanomedicine into a new light. This review highlights the various pathological issues involved in secondary spinal cord injury, current treatment options, and the improvements that could be made using a nanomedical approach.

    2017-01-01

    Extensive research is ongoing that concentrates on finding therapies to enhance CNS regeneration after spinal cord injury (SCI) and to cure paralysis. This review sheds light on the role of the FGFR pathway in the injured spinal cord and discusses various therapies that use FGFR activating ligands to promote regeneration after SCI. We discuss studies that use peripheral nerve grafts or Schwann cell grafts in combination with FGF1 or FGF2 supplementation. Most of these studies show evidence that these therapies successfully enhance axon regeneration into the graft. Further they provide evidence for partial recovery of sensory function shown by electrophysiology and motor activity evidenced by behavioural data. We also present one study that indicates that combination with additional, synergistic factors might further drive the system towards functional regeneration. In essence, this review summarises the potential of nerve and cell grafts combined with FGF1/2 supplementation to improve outcome even after severe spinal cord injury. PMID:28197342

    Little is known about cell death in spinal cord tissue following compression injury, despite compression being a key component of spinal injuries. Currently models are used to mimic compression injury in animals and the effects of the compression evaluated by observing the extent and duration of recovery of normal motor function in the days and weeks following the injury. A fibreoptic photoplethysmography system was used to investigate whether pulsation of the small arteries in the spinal cord occurred before, during and after compressive loads were applied to the tissue. It was found that the signal amplitudes were reduced and this reduction persisted for at least five minutes after the compression ceased. It is hoped that results from this preliminary study may improve knowledge of the mechanism of spinal cord injury.

    Spinal cord injury (SCI) is a complex and devastating condition characterized by disruption of descending, ascending, and intrinsic spinal circuitry resulting in chronic neurologic deficits. In addition to limb and trunk sensorimotor deficits, SCI can impair autonomic neurocircuitry such as the motor networks that support respiration and cough. High cervical SCI can cause complete respiratory paralysis, and even lower cervical or thoracic lesions commonly result in partial respiratory impairment. Although electrophrenic respiration can restore ventilator-independent breathing in select candidates, only a small subset of affected individuals can benefit from this technology at this moment. Over the past decades, spinal cord stimulation has shown promise for augmentation and recovery of neurologic function including motor control, cough, and breathing. The present review discusses the challenges and potentials of spinal cord stimulation for restoring respiratory function by overcoming some of the limitations of conventional respiratory functional electrical stimulation systems.

    Panayiotou, Elena; Malas, Stavros

    2013-11-28

    Spinal cord injury (SCI) is a major health burden and currently there is no effective medical intervention. Research performed over the last decade revealed that cells surrounding the central canal of the adult spinal cord and forming the ependymal layer acquire stem cell properties either in vitro or in response to injury. Following SCI activated ependymal cells generate progeny cells which migrate to the injury site but fail to produce the appropriate type of cells in sufficient number to limit the damage, rendering this physiological response mainly ineffective. Research is now focusing on the manipulation of ependymal cells to produce cells of the oligodendrocyte lineage which are primarily lost in such a situation leading to secondary neuronal degeneration. Thus, there is a need for a more focused approach to understand the molecular properties of adult ependymal cells in greater detail and develop effective strategies for guiding their response during SCI.

    Full Text Available Sweat production is crucial for thermoregulation. However, sweating can be problematic for individuals with spinal cord injuries (SCI, as they display a blunting of sudomotor and vasomotor responses below the level of the injury. Sweat gland density and eccrine gland metabolism in SCI are not well understood. Consequently, this study examined sweat lactate (S-LA (reflective of sweat gland metabolism, active sweat gland density (SGD, and sweat output per gland (S/G in 7 SCI athletes and 8 able-bodied (AB controls matched for arm ergometry VO2peak. A sweat collection device was positioned on the upper scapular and medial calf of each subject just prior to the beginning of the trial, with iodine sweat gland density patches positioned on the upper scapular and medial calf. Participants were tested on a ramp protocol (7 min per stage, 20 W increase per stage in a common exercise environment (21±1°C, 45-65% relative humidity. An independent t-test revealed lower (p<0.05 SGD (upper scapular for SCI (22.3 ±14.8 glands · cm-2 vs. AB. (41.0 ± 8.1 glands · cm-2. However, there was no significant difference for S/G between groups. S-LA was significantly greater (p<0.05 during the second exercise stage for SCI (11.5±10.9 mmol · l-1 vs. AB (26.8±11.07 mmol · l-1. These findings suggest that SCI athletes had less active sweat glands compared to the AB group, but the sweat response was similar (SLA, S/G between AB and SCI athletes. The results suggest similar interglandular metabolic activity irrespective of overall sweat rate.

    Abstract Chronic pain and dysesthesias are debilitating conditions that can arise following spinal cord injury (SCI). Research studies frequently employ rodent models of SCI to better understand the underlying mechanisms and develop better treatments for these phenomena. While evoked withdrawal tests can assess hypersensitivity in these SCI models, there is little consensus over how to evaluate spontaneous sensory abnormalities that are seen in clinical SCI subjects. Overgrooming (OG) and biting after peripheral nerve injury or spinal cord excitotoxic lesions are thought to be one behavioral demonstration of spontaneous neuropathic pain or dysesthesia. However, reports of OG after contusion SCI are largely anecdotal and conditions causing this response are poorly understood. The present study investigated whether repeated application of sensory stimuli to the trunk prior to mid-thoracic contusion SCI would induce OG after SCI in mice. One week prior to SCI or laminectomy, mice were subjected either to nociceptive and mechanical stimulation, mechanical stimulation only, the testing situation without stimulation, or no treatment. They were then examined for 14 days after surgery and the sizes and locations of OG sites were recorded on anatomical maps. Mice subjected to either stimulus paradigm showed increased OG compared with unstimulated or uninjured mice. Histological analysis showed no difference in spinal cord lesion size due to sensory stimulation, or between mice that overgroomed or did not overgroom. The relationship between prior stimulation and contusion injury in mice that display OG indicates a critical interaction that may underlie one facet of spontaneous neuropathic symptoms after SCI.

    Men constitute 82% of the approximately 250,000 people in the United States living with a spinal cord injury. Unfortunately, however, little is known about the impact of men's adherence to gender norms on their adjustment to such injuries. The present investigation examined the utility of masculine norms in explaining variance in depression beyond that accounted for by commonly identified predictors of men's adjustment following spinal cord injury. As hypothesized, results suggested that men's adherence to masculine norms accounted for unique variance in their depression scores beyond that contributed by social support, environmental barriers/access, and erectile functioning. Respondents who adhered to norms stressing the primacy of men's work demonstrated lower rates of depression, whereas those who conformed to norms for self-reliance demonstrated higher depression scores. The authors discuss future research directions and potential psychotherapeutic strategies for working with men with spinal cord injuries.

    Occupational therapists frequently prescribe wheelchair cushions to reduce the risk of pressure sores in patients with spinal cord injury. In an earlier study (Garber, 1985b), Roho cushions were prescribed for the greatest number of subjects studied. The present study of 197 subjects updates these data and describes current prescription patterns, the use of cushions over time, satisfaction with prescribed cushions, and the occurrence of pressure sores with prescribed cushions. The study shows that the Jay cushion was prescribed most frequently for the current subjects, although it was not recommended for all persons with spinal cord injury. In the second phase of the present study, involving 30 subjects, 30% of the subjects discontinued use of the prescribed cushion. Skin breakdown and the discovery of alternative solutions were given as primary reasons. There was no significant difference in the incidence of pressure sores between subjects who continued to use their prescribed cushions and those who did not. This research supports the conclusion of earlier studies that no one wheelchair cushion is universally effective for all persons and that individual evaluation and routine reassessment are essential in reducing the occurrence of pressure sores.

    Full Text Available Background. An acute spinal cord injury (ASCI is a severe condition that requires extensive and very specialized management of both physical and psychological dimensions of injured patients. Objective. The aim of the part of the study reported here was twofold: (1 to describe burnout, empathy, and satisfaction at work of these professionals and (2 to explore whether a tailored program based on motivational interviewing (MI techniques modifies and improves such features. Methods. This paper presents findings from an intervention study into a tailored training for professionals (N=45 working in a spinal cord injury (SCI unit from a general hospital. Rehabilitation professionals’ empathy skills were measured with the Jefferson Scale of Physician Empathy (JSPE, burnout was measured with the Maslach Burnout Inventory (MBI, and additional numeric scales were used to assess the perceived job-related stress and perceived satisfaction with job. Results. Findings suggest that professionals are performing quite well and they refer to satisfactory empathy, satisfaction at work, and no signs of burnout or significant stress both before and after the training. Conclusions. No training effect was observed in the variables considered in the study. Some possible explanations for these results and future research directions are discussed in depth in this paper.

    2017-06-01

    Chronic neuropathic pain is a complicated condition after a spinal cord injury (SCI) that often has a lifelong and significant negative impact on life after the injury; therefore, improved pain management is considered a significant and unmet need. Neuropathic pain mechanisms are heterogeneous and the difficulty in determining their individual contribution to specific pain types may contribute to poor treatment outcomes in this population. Thus, identifying human neuropathic pain phenotypes based on pain symptoms, somatosensory changes, or cognitive and psychosocial factors that reflect specific spinal cord or brain mechanisms of neuropathic pain is an important goal. Once a pain phenotype can be reliably replicated, its relationship with biomarkers and clinical treatment outcomes can be analyzed, and thereby facilitate translational research and further the mechanistic understanding of individual differences in the pain experience and in clinical trial outcomes. The present article will discuss clinical aspects of SCI-related neuropathic pain, neuropathic pain phenotypes, pain mechanisms, potential biomarkers and pharmacological interventions, and progress regarding how defining neuropathic pain phenotypes may lead to more targeted treatments for these difficult pain conditions.

    Background/objective Length of stay (LOS) for rehabilitation treatment after spinal cord injury (SCI) has been documented extensively. However, there is almost no published research on the nature, extent, or intensity of the various treatments patients receive during their stay. This study aims at providing such information on a large sample of patients treated by specialty rehabilitation inpatient programs. Methods Six hundred patients with traumatic SCI admitted to six rehabilitation centers were enrolled. Time spent on various therapeutic activities was documented by each rehabilitation clinician after each patient encounter. Patients were grouped by neurologic level and completeness of injury. Total time spent by each rehabilitation discipline over a patient's stay and total minutes of treatment per week were calculated. Ordinary least squares stepwise regression models were used to identify patient and injury characteristics associated with time spent in rehabilitation treatment overall and within each discipline. Results Average LOS was 55 days (standard deviation 37), during which 180 (106) hours of treatment were received, or 24 (5) hours per week. Extensive variation was found in the amount of treatment received, between and within neurologic groups. Total hours of treatment provided throughout a patient's stay were primarily determined by LOS, which in turn was primarily predicted by medical acuity. Variation in minutes per week of treatment delivered by individual disciplines was predicted poorly by patient and injury characteristics. Conclusions Variations between and within SCI rehabilitation patient groups in LOS, minutes of treatment per week overall, and for each rehabilitation discipline are large. Variation in treatment intensity was not well explained by patient and injury characteristics. In accordance with practice-based evidence methodology, the next step in the SCIRehab study will be to determine which treatment interventions are related with

    Full Text Available During the last few decades, focus of rehabilitation outcome has been redirected to the lifetime monitoring of quality of life. The purpose of this study was to investigate the differences in quality of life perceptions between participants with spinal cord injury and participants of typical population.This cross-sectional controlled study of 100 adults aged 18-65 years was based on two questionnaires, Short Form-36 Health Survey (SF-36 and Spinal Cord Injury Quality of Life Questionnaire (QL-23, completed by 23 participants with paraplegia, 21 participants with tetraplegia, and 56 participants of typical population. Mann-Whitney U-test for planned comparison between groups and χ(2 test were used to analyze the differences between research groups.Participants from control group perceived their general quality of life at higher level in comparison to participants with spinal cord injury (U=415.000, z=-5.804, P<0.000. Negative influence of spinal cord injury was detected in six domains (physical functioning, physical role, bodily pain, vitality, social functioning, mental health. Statistical differences between participants with paraplegia and participants with tetraplegia only in domain of functional limitations (U=103.000, z=-3.256, P<0.005.The participants with spinal cord injury perceived both health-related and general quality of life at a lower level in comparison to controls. However, the injury level only partially determined the estimated quality of life.

    Full Text Available Abstract Background Spinal cord injury is a serious and debilitating condition, affecting millions of people worldwide. Long seen as a permanent injury, recent advances in stem cell research have brought closer the possibility of repairing the spinal cord. One such approach involves injecting oligodendrocyte progenitor cells, derived from human embryonic stem cells, into the injured spinal cord in the hope that they will initiate repair. A phase I clinical trial of this therapy was started in mid 2010 and is currently underway. Discussion The theory underlying this approach is that these myelinating progenitors will phenotypically replace myelin lost during injury whilst helping to promote a repair environment in the lesion. However, the importance of demyelination in the pathogenesis of human spinal cord injury is a contentious issue and a body of literature suggests that it is only a minor factor in the overall injury process. Summary This review examines the validity of the theory underpinning the on-going clinical trial as well as analysing published data from animal models and finally discussing issues surrounding safety and purity in order to assess the potential of this approach to successfully treat acute human spinal cord injury.

    Spinal cord injury causes neuronal death, limiting subsequent regeneration and recovery. Thus, there is a need to develop strategies for improving neuronal survival after injury. Relative to our understanding of axon regeneration, comparatively little is known about the mechanisms that promote the survival of damaged neurons. To address this, we took advantage of lamprey giant reticulospinal neurons whose large size permits detailed examination of post-injury molecular responses at the level of individual, identified cells. We report here that spinal cord injury caused a select subset of giant reticulospinal neurons to accumulate synuclein, a synaptic vesicle-associated protein best known for its atypical aggregation and causal role in neurodegeneration in Parkinson’s and other diseases. Post-injury synuclein accumulation took the form of punctate aggregates throughout the somata and occurred selectively in dying neurons, but not in those that survived. In contrast, another synaptic vesicle protein, synaptotagmin, did not accumulate in response to injury. We further show that the post-injury synuclein accumulation was greatly attenuated after single dose application of either the “molecular tweezer” inhibitor, CLR01, or a translation-blocking synuclein morpholino. Consequently, reduction of synuclein accumulation not only improved neuronal survival, but also increased the number of axons in the spinal cord proximal and distal to the lesion. This study is the first to reveal that reducing synuclein accumulation is a novel strategy for improving neuronal survival after spinal cord injury. PMID:26854933

    In a group of 520 patients with injury to the spine and spinal cord 125 died within 10 years. The highest fatality rate (76.0 +/0 3.8) is recorded in the first year after the injury. In the following 10 years the fatality rate was uniform and ranged between 1.6 and 4.1%. This value increases with the patient's age, the severity of the spinal cord injury, and the degree of damage to the spinal ligamento-bursal apparatus. Among the total number of injured, 76% have a survival period of more than 10 years.

    Full Text Available Background: Spinal cord injury (SCI imposes a significant burden on the social and marital life. Here, we assessed the divorce rate and changes in marital status among a sample of Iranian individuals with SCI.Methods: Referred patients to Brain and Spinal Cord Injury Research Center were invited to participate in this cross-sectional investigation. The Main exclusion criteria were coincidental brain injury, history of chronic diseases before SCI and substance use. Demographic characteristics (including age, gender, educational level, marital status before and after injury and duration of marriage and Injury characteristics (level of the injury, American spinal injury association (ASIA scale and Spinal cord independence measure III (SCIM were collected.Results: Total of 241 subjects with SCI participated in this investigation (164 (68% male and 77 (32% female. Among men, 16.5% [95% CI: 10.81%-22.18%] and among women 18.2% [95% CI: 9.58%-26.81%] got divorced after injury. Duration of marriage before injury was significantly related to lower divorce rate (P< 0.001 and 0.016 in men and women, respectively. Injury characteristics had no relationship with marital longevity. Age was a protective factor against marital dissolution only in men (P< 0.004.Conclusion: Our study revealed the divorce rate of 17% [95% CI: 13%-20.9%] after SCI in a sample of Iranian population. The protective influence of age in maintenance of marriage was only detected in men, which proposes existence of a sexual polymorphism in the role of age. Divorce rate was similar between two genders and injury characteristics were not related to divorce rate as well. Keywords: Marital status, Spinal cord injury, Divorce, Iran

The secondary injury results from the biological cascade after the primary injury and affects previous uninjured, healthy tissue. Therefore, the mitigation of such a cascade would benefit patients suffering a primary injury and allow the body to recover more quickly. Unfortunately, the delivery of effective therapeutics is quite limited. Due to the inefficient delivery of therapeutic drugs, nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help treat disease by delivering drugs to specific tissues, enhancing detection methods, or a mixture of both. Incorporating nanomedicine into the treatment of neuronal injury and disease would likely push nanomedicine into a new light. This review highlights the various pathological issues involved in secondary spinal cord injury, current treatment options, and the improvements that could be made using a nanomedical approach.

    Full Text Available Spinal cord injury results in the permanent loss of function, causing enormous personal, social and economic problems. Even though neural regeneration has been proven to be a natural mechanism, central nervous system repair mechanisms are ineffective due to the imbalance of the inhibitory and excitatory factors implicated in neuroregeneration. Therefore, there is growing research interest on discovering a novel therapeutic strategy for effective spinal cord injury repair. To this direction, cell-based delivery strategies, biomolecule delivery strategies as well as scaffold-based therapeutic strategies have been developed with a tendency to seek for the answer to a combinatorial approach of all the above. Here we review the recent advances on regenerative/neural engineering therapies for spinal cord injury, aiming at providing an insight to the most promising repair strategies, in order to facilitate future research conduction.

    Objective:To investigate the effects of epidural spinal cord stimulation (ESCS) and treadmill training on the locomotion function and ultrastructure of spinal cord anterior horn after moderate spinal cord injury in rats. (IT, n=3). All rats received a moderate spinal cord injury surgery. Four weeks after surgery, rats in SE group received an electrode implantation procedure, with the electrode field covering spinal cord segments L2-S1. Four weeks after electrode implantation, rats received subthreshold ESCS for 30 min/d. Rats in TY group received 4cm/s treadmill training for 30min/d. Rats in SI group received no intervention, as a control group. All procedures in these three groups lasted four weeks.The open field Basso,Beattie and Bresnahan (BBB) scale was used before and after intervention to evaluate rats' hindlimb motor function. Result:After four weeks intervention, rats in TT group improved their open field locomotion scores to 20. In contrast, no significant improvement was observed in groups SI and SE. The morphology of synapses and neurons were similar regardless of whether rats had undergone ESCS, treadmill training or not. Conclusion:ESCS alone was not sufficient to improve the walking ability of spinal cord injured rats. ESCS or treadmill training alone might not contribute to the changes of ultrastructure in anterior horn of spinal cord that underlie the recovery of walking ability. Further research is needed to understand the contributions of combination of ESCS and treadmill training to the rehabilitation of spinal cord injured rats.

    Full Text Available Spinal cord injury occurring without concomitant radiologically demonstrable trauma to the skeletal elements of the spinal canal rim, or compromise of the spinal canal rim without fracture, is a rare event. Though documented in children, the injury is not very well reported in adults. We present seventeen adult patients with spinal cord injury without accompanying fracture of the spinal canal rim, or vertebral dislocation, seen over seven years. None had preexisting spinal canal stenosis or cervical spondylosis. Following trauma, these patients had weakness of all four limbs. They were evaluated by MRI (CT scan in one patient, which showed hypo / isointense lesion in the cord on T1 weighted images, and hyperintensity on T2 weighted images, suggesting cord contusion or oedema. MRI was normal in two patients. With conservative management, fifteen patients showed neurological improvement, one remained quadriplegic and one died. With increasing use of MRI in the evaluation of traumatic myelopathy, such injuries will be diagnosed more often. The mechanism of injury is probably acute stretching of the cord as in flexion and torsional strain. Management is essentially conservative and prognosis is better than that seen in patients with fracture or dislocation of cervical spine.

    The objective of this study was to review recent findings about the prevalence of substance use (SU) and substance use disorders (SUD), and to discuss the related impact on health in spinal cord injury (SCI) population. For this purpose, computer-aided searches of MEDLINE (PubMed) and the Cochrane Library were conducted. From an initial pool of 59 articles, 52 met the inclusion criteria. Most of the studies referred to alcohol and tobacco and only a few studies reported on other substances. Study designs were mainly cross-sectional and descriptive, with scarce intervention and longitudinal studies.  Although a high prevalence of post-injury SU has been documented among SCI patients, limited research exists on pre-injury SU and on longitudinal studies. Moreover, when exploring SUD, it has not been systematically studied in accordance with CIE or DSM criteria. Alcohol appears to be the most consumed substance among this population. Additionally, those patients with SU have shown poorer outcomes in different health indicators. Therefore, more insight is required to increase scientific knowledge in this field and to recommend tailored preventive interventions and research priorities in relation to this population.

    Paralysis due to spinal cord injury can severely limit motor function and independence. This review summarizes different approaches to electrical stimulation of the spinal cord designed to restore motor function, with a brief discussion of their origins and the current understanding of their mechanisms of action. Spinal stimulation leads to impressive improvements in motor function along with some benefits to autonomic functions such as bladder control. Nonetheless, the precise mechanisms underlying these improvements and the optimal spinal stimulation approaches for restoration of motor function are largely unknown. Finally, spinal stimulation may augment other therapies that address the molecular and cellular environment of the injured spinal cord. The fact that several stimulation approaches are now leading to substantial and durable improvements in function following spinal cord injury provides a new perspectives on the previously "incurable" condition of paralysis.

    Mouse models have provided key insight into the cellular and molecular control of human immune system function. However, recent data indicate that extrapolating the functional capabilities of the murine immune system into humans can be misleading. Since immune cells significantly affect neuron survival and axon growth and also are required to defend the body against infection, it is important to determine the pathophysiological significance of spinal cord injury (SCI)-induced changes in human immune system function. Research projects using monkeys or humans would be ideal; however, logistical and ethical barriers preclude detailed mechanistic studies in either species. Humanized mice, i.e., immunocompromised mice reconstituted with human immune cells, can help overcome these barriers and can be applied in various experimental conditions that are of interest to the SCI community. Specifically, newborn NOD-SCID-IL2rg(null) (NSG) mice engrafted with human CD34(+) hematopoietic stem cells develop normally without neurological impairment. In this report, new data show that when mice with human immune systems receive a clinically-relevant spinal contusion injury, spontaneous functional recovery is indistinguishable from that achieved after SCI using conventional inbred mouse strains. Moreover, using routine immunohistochemical and flow cytometry techniques, one can easily phenotype circulating human immune cells and document the composition and distribution of these cells in the injured spinal cord. Lesion pathology in humanized mice is typical of mouse contusion injuries, producing a centralized lesion epicenter that becomes occupied by phagocytic macrophages and lymphocytes and enclosed by a dense astrocytic scar. Specific human immune cell types, including three distinct subsets of human monocytes, were readily detected in the blood, spleen and liver.

    Abstract Objectives Studying the quality of life of people with a spinal cord injury is of great importance as it allows the monitoring of both functioning and adaptation to disability. The aim of this study was to determine the difference between persons with a spinal cord injury involved in sports activities and those not involved in sports activities in relation to their quality of life and the presence of secondary health conditions (pressure ulcers, urinary infections, muscle spasms, osteoporosis, pain, kidney problems-infections, calculosis and poor circulation). Methods The study included a total of 44 participants with spinal cord injury-paraplegia of both genders; 26 of them were athletes and 18 were not athletes. The athletes were training actively for the last two years, minimally 2-3 times per week. A specially designed questionnaire, medical documentation and the Spinal Cord Injury Quality of Life Questionnaire (SCI QL-23) were used for research purposes. Chi-square test was used to analyze the differences between the groups, while multiple analysis of variance (MANOVA) was used to determine the differences between the sets of variables. Results Among the participants, the athletes perceived higher quality of life than the non-athletes (male gender psubjective feeling of better circulation (p=0.023). Conclusion The implementation of sports activities significantly improves quality of life in the population of people with spinal cord injury-paraplegia. However, sports activities only partially affect secondary health conditions. PMID:27284378

    Spinal cord injuries are damages that result in complete or partial loss of sensation and/or mobility and affect the life qualities of many patients. Their pathophysiology in-cludes primary and secondary processes, which are related with the activation of astrocytes and microgliacytes and the degeneration of oligodendrocytes. Although transplan-tation of embryonic stem cells or neural progenitor cells is an attractive strategy for repair of the injured central ner-vous system (CNS), transplantation of these cells alone for acute spinal cord injuries has not resulted in robust axon regeneration beyond the injury sites. This may be due to the progenitor cells differentiating to the cell types that sup-port axon growth poorly and/or their inability to modify the inhibitory environment of adult CNS after injury. Recent studies indicate that transplantation of glial progenitor cells has exhibited beneficial effects on the recovery and promis-ing future for the therapy strategy of spinal cord injury. In this review, we summarized the data from recent literature regarding glial implications in transplantation therapy of spinal cord injury.

    2012-04-01

    Full Text Available The injury of the Spine cord is a major problem because of the high mortality and morbidity in patients. Despite the advanced medical care and specialized rehabilitation the life expectancy of people with injuries of the spinal cord is lower than the general population. Hospitalization in modern rehabilitation centers reduces the mortality and severity of the complications with comprehensive programs which include the prevention of complications. It also educates the patient and his carer with psychological and social support. The nursing interventions have perhaps the most significant impact on the area of functional independence, rehabilitation and the quality of the patients life. The development of better rehabilitation programs will improve the life of people with injury of the spine and Spinal Cord.

    Full Text Available Objective. To describe the lifestyle of adults with spinal cord injury and explore its relation with some health conditions. Methodology. Cross sectional study, in which a questionnaire containing sociodemographic, habits and health conditions variables was used. Forty-seven people with spinal cord injury participated and answered the self-report questionnaire. Results. The group under study was predominantly male (92%, under 40 years of age (47%, and had low educational level (76%. The most frequent risk factors related to the lifestyle were: smoking (28%, alcohol consumption (36%, coffee consumption (92% and being physically inactive (64%. Association was found between having four or more risk factors related to lifestyle and the loss of appetite, as well as constipation. Conclusion. The actual inadequate lifestyle is associated with the health conditions of patients, and the nursing team should pay special attention to the education and promotion of health related to people with spinal cord injury.

    This investigation was undertaken to study the early protective effects of Iloprost, a stable analogue of prostacyclin, after spinal cord injury in rabbit. Sixteen adult male rabbits (New Zealand Albino) were injured by application of epidural aneurysm clip. Eight rabbits received an intravenous (i.v.) infusion of 30 micrograms kg-1 Iloprost, and eight rabbits received an infusion of saline (SF). Treatment with Iloprost started immediately after spinal cord injury and continued for one hour. Evoked potentials were recorded for each rabbit at one, 15, and 60 minutes after the spinal cord injury. Twenty-four hours later, all the rabbits were deeply anesthetized and spinal cords were removed for histopathological examinations. There was no meaningful statistical difference between cortical somatosensorial evoked potentials (CSEP) of the saline and Iloprost group. However, light and electron microscopic studies showed that the Iloprost treated group had moderate protection of myelin and axons; and limited edema. These results suggest that intravenous Iloprost treatment after spinal cord injury has a highly protective effect without any side effects.

    Traumatic insults to the spinal cord induce both immediate mechanical damage and subsequent tissue degeneration leading to a substantial physiological, biochemical, and functional reorganization of the spinal cord. Various spinal cord injury (SCI) models have shown the adaptive potential of the spinal cord and its limitations in the case of total or partial absence of supraspinal influence. Meaningful recovery of function after SCI will most likely result from a combination of therapeutic strategies, including neural tissue transplants, exogenous neurotrophic factors, elimination of inhibitory molecules, functional sensorimotor training, and/or electrical stimulation of paralyzed muscles or spinal circuits. Peripheral nerve grafts provide a growth-permissive substratum and local neurotrophic factors to enhance the regenerative effort of axotomized neurons when grafted into the site of injury. Regenerating axons can be directed via the peripheral nerve graft toward an appropriate target, but they fail to extend beyond the distal graft-host interface because of the deposition of growth inhibitors at the site of SCI. One method to facilitate the emergence of axons from a graft into the spinal cord is to digest the chondroitin sulfate proteoglycans that are associated with a glial scar. Importantly, regenerating axons that do exit the graft are capable of forming functional synaptic contacts. These results have been demonstrated in acute injury models in rats and cats and after a chronic injury in rats and have important implications for our continuing efforts to promote structural and functional repair after SCI.

    Objective. Powered exoskeletons promise to increase the quality of life of people with lower-body paralysis or weakened legs by assisting or restoring legged mobility while providing health benefits across multiple physiological systems. Here, a systematic review of the literature on powered exoskeletons addressed critical questions: What is the current evidence of clinical efficacy for lower-limb powered exoskeletons? What are the benefits and risks for individuals with spinal cord injury (SCI)? What are the levels of injury considered in such studies? What are their outcome measures? What are the opportunities for the next generation exoskeletons? Approach. A systematic search of online databases was performed to identify clinical trials and safety or efficacy studies with lower-limb powered exoskeletons for individuals with SCI. Twenty-two studies with eight powered exoskeletons thus selected, were analyzed based on the protocol design, subject demographics, study duration, and primary/secondary outcome measures for assessing exoskeleton's performance in SCI subjects. Main results. Findings show that the level of injury varies across studies, with T10 injuries being represented in 45.4% of the studies. A categorical breakdown of outcome measures revealed 63% of these measures were gait and ambulation related, followed by energy expenditure (16%), physiological improvements (13%), and usability and comfort (8%). Moreover, outcome measures varied across studies, and none had measures spanning every category, making comparisons difficult. Significance. This review of the literature shows that a majority of current studies focus on thoracic level injury as well as there is an emphasis on ambulatory-related primary outcome measures. Future research should: 1) develop criteria for optimal selection and training of patients most likely to benefit from this technology, 2) design multimodal gait intention detection systems that engage and empower the user, 3) develop

    Spinal cord injury devastates the CNS, besetting patients with symptoms including but not limited to: paralysis, autonomic nervous dysfunction, pain disorders and depression. Despite the identification of several molecular and genetic factors, a reliable regenerative therapy has yet to be produced for this terminal disease. Perhaps the missing piece of this puzzle will be discovered within endogenous electrotactic cellular behaviors. Neurons and stem cells both show mediated responses (growth rate, migration, differentiation) to electromagnetic waves, including direct current electric fields. This review analyzes the pathophysiology of spinal cord injury, the rationale for regenerative cell therapy and the evidence for directing cell therapy via electromagnetic waves shown by in vitro experiments.

    2004-10-01

    Basic science advances in spinal cord injury and regeneration research have led to a variety of novel experimental therapeutics designed to promote functionally effective axonal regrowth and sprouting. Among these interventions are cell-based approaches involving transplantation of neural and non-neural tissue elements that have potential for restoring damaged neural pathways or reconstructing intraspinal synaptic circuitries by either regeneration or neuronal/glial replacement. Notably, some of these strategies (e.g., grafts of peripheral nerve tissue, olfactory ensheathing glia, activated macrophages, marrow stromal cells, myelin-forming oligodendrocyte precursors or stem cells, and fetal spinal cord tissue) have already been translated to the clinical arena, whereas others have imminent likelihood of bench-to-bedside application. Although this progress has generated considerable enthusiasm about treating what once was thought to be a totally incurable condition, there are many issues to be considered relative to treatment safety and efficacy. The following review reflects on different experimental applications of intraspinal transplantation with consideration of the underlying pathological, pathophysiological, functional, and neuroplastic responses to spinal trauma that such treatments may target along with related issues of procedural and biological safety. The discussion then moves to an overview of ongoing and completed clinical trials to date. The pros and cons of these endeavors are considered, as well as what has been learned from them. Attention is primarily directed at preclinical animal modeling and the importance of patterning clinical trials, as much as possible, according to laboratory experiences.

    Numerical techniques were used to study the mechanisms of acute central cord syndrome. To analyze the features of stress distribution in the cervical cord under different injury conditions using finite element model of the cervical cord and to improve the understanding of the possible pathogenesis of acute central cord syndrome. Acute central cord spinal injury was initially attributed to hemorrhagic damage to the central portion of the spinal cord, but recent histopathologic studies showed that it was predominantly a white matter injury. The precise anatomic location of neuronal injury and the etiology of the clinical manifestation were poorly understood. Cervical cord injury was simulated using a finite element model of the cervical enlargement described previously, with the model loaded under 3 traumatic postures: neutral, flexion, and extension. Five traumatic conditions were simulated and analyzed: hyperextension with the pinch force directed to the anterior (A) or posterior (B); flexion injuries (C), vertical compression with the pinch force directed to the anterior (D) or posterior (E). After simulation, several representative cross-sections of each traumatic pattern were selected. In each cross-section, the average von Mises stress of 9 regions, such as anterior funiculus, lateral part of the lateral funiculus, medial part of the lateral funiculus, lateral part of the posterior funiculus, medial part of the posterior funiculus, anterior horn, the bottom of anterior horn, the cervix cornu posterioris, the caput cornu posterioris, and the apex cornu posterioris was recorded. High localized stress occurred at the portion under compression injury and the level above it. High localized stress tended to occur at the lateral part of the anterior horn motor neurons innervating the hand muscles in traumatic conditions A and D. Under conditions A, D, and E, the average localized stress at the anterior and posterior horn of the gray matter was higher than that at the

  3. Traumatic spinal cord injury: current concepts and treatment update

    Carolina Rouanet

    Full Text Available ABSTRACT Spinal cord injury (SCI affects 1.3 million North Americans, with more than half occurring after trauma. In Brazil, few studies have evaluated the epidemiology of SCI with an estimated incidence of 16 to 26 per million per year. The final extent of the spinal cord damage results from primary and secondary mechanisms that start at the moment of the injury and go on for days, and even weeks, after the event. There is convincing evidence that hypotension contributes to secondary injury after acute SCI. Surgical decompression aims at relieving mechanical pressure on the microvascular circulation, therefore reducing hypoxia and ischemia. The role of methylprednisolone as a therapeutic option is still a matter of debate, however most guidelines do not recommend its regular use. Neuroprotective therapies aiming to reduce further injury have been studied and many others are underway. Neuroregenerative therapies are being extensively investigated, with cell based therapy being very promising.

    Spinal cord injury (SCI) occurs within seconds, but host responses may take years. Although life expectancy has increased, half of the survivors end up as paraplegics, with many indeed as quadriplegics. Host responses may have multiple effects ranging from inhibiting inflammation to preventing repair and regeneration. Efforts seek to translate exciting results from unsatisfactory animal models to humans. The author reviews the current basic and translational research for SCI treatment that: i) limits secondary injury; and ii) enhances endogenous repair and regeneration. The article provides an emphasis on pro-inflammatory factors (TNF-α, high-mobility group B protein 1) that are targeted to encourage healing. Research in the coming years needs to be directed at therapeutic agents - whether drugs, biologics or biomaterials - that encourage repair and regeneration and, at the same time, limit cell death and axonal lesions. The author believes that the process of harnessing the power of these innate responses will remain the challenge for the future in the quest for effective therapeutic options.

    Objective: To observe the clinical efficacy of the embryonic spinal cellular transplantation and greater omental transposition for treatment of the spinal cord injury in 24 mongrel dogs. Methods: 24 adult mongrel dogs, weighing 10 ~ 13kg,bryonic spinal cellular transplantation and greater omental transposition group (group D). Each group consisted of 6 dogs. SEP(somatosensory evoked potential) and MEP (motor evoked potential) of the spinal cord were examed prior to the spinal cord injury and 2 months after the treatment to observe the changes of the animals' behavior. All dogs were killed 2 months after surgery and the spinal cord sections were obtained from T12 to L1 level for pathological analysis and observation under the electron microscope.Results: There was an obvious difference in the spinal somatosensory evoked potential and the motor evoked potential between the group D and the other three groups (group A, B, and C). Recovery of the behavior was noted. The spinal cells had survived for two months following the transplantation. Conclusion: Transplantation of the embryonic spinal cell and greater omentum for treatment of the spinal cord injury in dogs can gain a better outcome than the other groups in behavior and spinal somatosensory and motor evoked potential, but the further study is still essential to confirm its clinical efficacy.

    The aim of this study was to examine changes in passive length and stiffness of the gastrocnemius muscle-tendon unit in people after spinal cord injury. In a prospective longitudinal study, eight wheelchair-dependent participants with severe paralysis were assessed 3 and 12 mos after spinal cord injury. Passive torque-angle data were obtained as the ankle was slowly rotated through range at six knee angles. Differences in passive ankle torque-angle data recorded at different knee angles were used to derive passive length-tension curves of the gastrocnemius muscle-tendon unit. Ultrasound imaging was used to determine fascicle and tendon contributions to the muscle-tendon unit length-tension curves. The participants had ankle contractures (mean [SD] maximum passive ankle dorsiflexion angle, 88 [9] degrees) 3 mos after spinal cord injury. Ankle range did not worsen significantly during the subsequent 9 mos (mean change, -5 degrees; 95% confidence interval, -16 to 6 degrees). There were no changes in the mean slack length or the stiffness of the gastrocnemius muscle-tendon unit or in the slack lengths of the fascicles or the tendon between 3 and 12 mos after spinal cord injury. There were no consistent patterns of the change in slack length or stiffness with the changes in ankle range in the data from the individual participants. This study, the first longitudinal study of muscle length and stiffness after spinal cord injury, showed that the length and the stiffness of the gastrocnemius did not change substantially between 3 and 12 mos after injury.

    Urinary tract infections remain the most frequent infection in patients with either traumatic or nontraumatic spinal cord inju-ry. The urinary tract infections are closely related to impaired bladder storage, voiding dysfunction, and use of indwelling catheters after spi-nal cord injury. Repeated urinary tract infections can cause upper urinary tract deterioration, and related chronic or repeated exposure to the antibiotics used to treat urinary tract infections increases the risk of multidrug-resistant bacteria colonization. Therefore, it is important to de-termine appropriate urinary tract infections treatment in spinal cord injury patients who are admitted to rehabilitation hospitals. The limita-tions of the usual measures in prevention of urinary tract infections in this population have led the way to explore more innovative modali-ties and approaches. We reviewed the researches of urinary tract infections on spinal cord injury. It is presented to provide reference for clini-cal diagnosis and treatment.%脊髓损伤患者的泌尿系感染通常与泌尿系结石、排空障碍以及应用导尿管相关,是创伤性或非创伤性脊髓损伤患者最常见的感染原因。反复泌尿系感染会引起肾功能损伤,而为了控制感染长期反复应用抗生素可能导致多重耐药菌定植进一步恶化感染。因此,康复阶段脊髓损伤患者泌尿系感染的预防、治疗方案的确定显得尤为重要。为了改善这类患者的预后,近年来各国研究者提出了许多新的临床经验及实验室方案,本文综述对脊髓损伤后泌尿系感染诊疗相关研究,以期对临床医疗提供借鉴。

    Spinal cord injury (SCI) results in loss of nervous tissue and consequently loss of motor and sensory function. There is no treatment available that restores the injury-induced loss of function to a degree that an independent life can be guaranteed. Transplantation of stem cells or progenitors may support spinal cord repair. Stem cells are characterized by self-renewal and their ability to become any cell in an organism. Promising results have been obtained in experimental models of SCI. Stem cells can be directed to differentiate into neurons or glia in vitro, which can be used for replacement of neural cells lost after SCI. Neuroprotective and axon regeneration-promoting effects have also been credited to transplanted stem cells. There are still issues related to stem cell transplantation that need to be resolved, including ethical concerns. This paper reviews the current status of stem cell application for spinal cord repair.

    to assess incidence, causes and socio-demographicaspects of traumatic spinal cord injury among patients over 65 in Asturias (Spain). A census was performed between 1951 and 2013 of patients in Asturias, over 65 years-old coded as «traumatic spinal cord injury with or without vertebral fracture». Socio-demographic, hospital and clinical variables were recorded. In total 180 patients were registered, most of them males (60%), with a mean age of 73 years (maximum 91). The estimated incidence in 2010 was found to be 24.9, in 2011, 28.9 and in 2012, 32.9 cases/million/year. The distribution in the type of injury was homogeneous and location in the cervical spine (40%) was found to be more common. There was bone injury in 71.4%, with multilevel injury in more than half of the cases. The main cause was accidental fall (52.1%), mainly at own height (68.6%), and most of them located in the cervical spine (38.5%), followed by traffic accidents with 57.6% located in the cervical spine. A change was observed in the epidemiological profile of the patients over 65 years old with spinal cord injury. There were more cases associated with accidental fall. It is necessary to create specific preventive and therapeutic strategies for this group. Copyright © 2015 SEGG. Publicado por Elsevier España, S.L.U. All rights reserved.

  12. Structural and functional reorganization of propriospinal connections promotes functional recovery after spinal cord injury

    Institute of Scientific and Technical Information of China (English)

    Linard Filli; Martin E Schwab

    2015-01-01

    Axonal regeneration and ifber regrowth is limited in the adult central nervous system, but re-search over the last decades has revealed a high intrinsic capacity of brain and spinal cord circuits to adapt and reorganize after smaller injuries or denervation. Short-distance ifber growth and synaptic rewiring was found in cortex, brain stem and spinal cord and could be associated with restoration of sensorimotor functions that were impaired by the injury. Such processes of struc-tural plasticity were initially observed in the corticospinal system following spinal cord injury or stroke, but recent studies showed an equally high potential for structural and functional reorganization in reticulospinal, rubrospinal or propriospinal projections. Here we review the lesion-induced plastic changes in the propriospinal pathways, and we argue that they represent a key mechanism triggering sensorimotor recovery upon incomplete spinal cord injury. The for-mation or strengthening of spinal detour pathways bypassing supraspinal commands around the lesion site to the denervated spinal cord were identiifed as prominent neural substrate inducing substantial motor recovery in different species from mice to primates. Indications for the exis-tence of propriospinal bypasses were also found in humans after cortical stroke. It is mandatory for current research to dissect the biological mechanisms underlying spinal circuit remodeling and to investigate how these processes can be stimulated in an optimal way by therapeutic inter-ventions (e.g., ifber-growth enhancing interventions, rehabilitation). This knowledge will clear the way for the development of novel strategies targeting the remarkable plastic potential of pro-priospinal circuits to maximize functional recovery after spinal cord injury.

  13. Structural and functional reorganization of propriospinal connections promotes functional recovery after spinal cord injury

    Full Text Available Axonal regeneration and fiber regrowth is limited in the adult central nervous system, but research over the last decades has revealed a high intrinsic capacity of brain and spinal cord circuits to adapt and reorganize after smaller injuries or denervation. Short-distance fiber growth and synaptic rewiring was found in cortex, brain stem and spinal cord and could be associated with restoration of sensorimotor functions that were impaired by the injury. Such processes of structural plasticity were initially observed in the corticospinal system following spinal cord injury or stroke, but recent studies showed an equally high potential for structural and functional reorganization in reticulospinal, rubrospinal or propriospinal projections. Here we review the lesion-induced plastic changes in the propriospinal pathways, and we argue that they represent a key mechanism triggering sensorimotor recovery upon incomplete spinal cord injury. The formation or strengthening of spinal detour pathways bypassing supraspinal commands around the lesion site to the denervated spinal cord were identified as prominent neural substrate inducing substantial motor recovery in different species from mice to primates. Indications for the existence of propriospinal bypasses were also found in humans after cortical stroke. It is mandatory for current research to dissect the biological mechanisms underlying spinal circuit remodeling and to investigate how these processes can be stimulated in an optimal way by therapeutic interventions (e.g., fiber-growth enhancing interventions, rehabilitation. This knowledge will clear the way for the development of novel strategies targeting the remarkable plastic potential of propriospinal circuits to maximize functional recovery after spinal cord injury.

    To investigate the occurrence and severity of traumatic brain injury in patients with traumatic spinal cord injury. Cross-sectional study with prospective neurological, neuropsychological and neuroradiological examinations and retrospective medical record review. Thirty-one consecutive, traumatic spinal cord injury patients on their first post-acute rehabilitation period in a national rehabilitation centre. The American Congress of Rehabilitation Medicine diagnostic criteria for mild traumatic brain injury were applied. Assessments were performed with neurological and neuropsychological examinations and magnetic resonance imaging 1.5T. Twenty-three of the 31 patients with spinal cord injury (74%) met the diagnostic criteria for traumatic brain injury. Nineteen patients had sustained a loss of consciousness or post-traumatic amnesia. Four patients had a focal neurological finding and 21 had neuropsychological findings apparently due to traumatic brain injury. Trauma-related magnetic resonance imaging abnormalities were detected in 10 patients. Traumatic brain injury was classified as moderate or severe in 17 patients and mild in 6 patients. The results suggest a high frequency of traumatic brain injury in patients with traumatic spinal cord injury, and stress a special diagnostic issue to be considered in this patient group.

    A 37-year-old man, amateur rugby player sustained a hyperextension injury to his lower thoracic spine during a scrum collapse. The patient developed extreme hyperpathia in the T10-12 dermatome, and parasthesia from T12 to S1 in the left lower limb. Medical Research Council grade 5 power was regained rapidly within minutes of the accident, and the hyperpathia resolved within a week. MRI showed contusion of the spinal cord at T10 level but no associated osseoligamentous injury. Six months later, parasthesia and subjective weakness remained in the left lower limb. To our knowledge, this is the first description of a lower thoracic spinal cord injury without radiographic abnormality following an isolated low-energy injury in a skeletally mature patient.

    Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI). Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. A mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain) pathways in the spinal cord may emerge in response to various noxious inputs, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord below the level of SCI. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Prior work from our group has shown that stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after SCI. We review these basic phenomena, how these findings relate to the broader spinal plasticity literature, discuss the cellular and molecular mechanisms, and finally discuss implications of these and other findings for improved rehabilitative therapies after SCI.

    1987-08-03

    A review of 107 footballers who suffered a spinal-cord injury between 1960 and 1985 has been undertaken. Since 1977, the number of such injuries in Rugby Union, Rugby League and Australian Rules has increased, from an average of about two injuries a year before 1977 to over eight injuries a year since then. Rugby Union is clearly the most dangerous game, particularly for schoolboys; all of the injuries in schoolboy games for this code have occurred since 1977. This study has shown that collision at scrum engagement, and not at scrum collapse, is the way in which the majority of scrum injuries are sustained. These injuries are largely preventable, and suggestions for rule changes are made. Half the injured players recovered to Frankel grades D or E. The financial entitlements of those injured were grossly inadequate; this warrants action. A national register for spinal-cord injuries from football should be established to monitor the effects of desirable rule changes in Rugby Union and Rugby League.

    This paper is a summary of a study of 72 cases of swimming-pool accidents resulting in serious injuries with the potential of permanent disability. Sixty-four of the 72 cases resulted in spinal cord injuries, 57 of which involved quadriplegic lesions. The authors observed that the majority of these injuries resulted from a lack of good judgement and common sense rather than from intoxication or pool structural deficiencies. Also of note was the lack of appropriate first-aid and extrication rendered, as well as the absence of uniform treatment and care received by the majority of the patients.

    Objective: To determine whether spinal cord decompression plays a role in neural cell apoptosis after spinal cord injury. Study design: We used an animal model of compressive spinal cord injury with incomplete paraparesis to evaluate neural cell apoptosis after decompression. Apoptosis and cellular damage were assessed by staining with terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate nick-end labelling (TUNEL) and immunostaining for caspase-3, Bcl-2 and Bax. Methods: Experiments were conducted in male Spragne-Dawley rats (n=78) weighing 300-400 g. The spinal cord was compressed posteriorly at T10 level using a custom-made screw for 6 h, 24 h or continuously, followed by decompression by removal of the screw. The rats were sacrificed on Day 1 or 3 or in Week 1 or 4 post-decompression. The spinal cord was removed en bloc and examined at lesion site, rostral site and caudal site (7.5 mm away from the lesion). Results: The numbers of TUNEL-positive cells were significantly lower at the site of decompression on Day l, and also at the rostral and caudal sites between Day 3 and Week 4 post-decompression, compared with the persistently compressed group. The numbers of cells between Day 1 and Week 4 were immunoreactive to caspase-3 and B-cell lymphoma-2 (Bcl-2)-associated X-protein (Bax), but not to Bcl-2, correlated with those of TUNEL-positive cells. Conclusion: Our results suggest that decompression reduces neural cell apoptosis following spinal cord injury.

    Using paired pulse transcranial magnetic stimulation (TMS) paradigms, we studied cortical excitability in a patient with spinal cord lesion. During posterior tibial nerve stimulation, the contextual flexion of hand fingers contralateral to the stimulated lower limb had suggested a change in motor cortex excitability. Results showed a decrease in the activity of motor cortex inhibitory circuits. This could suggest that in spinal cord injury, just as in stroke and peripheral deafferentation, a disinhibition of latent synapses within the motor cortex and the rewriting of a new motor map can occur.

  12. The role of propriospinal interneurons in recovery from spinal cord injury.

    2011-04-01

    Over one hundred years ago, Sir Charles Sherrington described a population of spinal cord interneurons (INs) that connect multiple spinal cord segments and participate in complex or 'long' motor reflexes. These neurons were subsequently termed propriospinal neurons (PNs) and are known to play a crucial role in motor control and sensory processing. Recent work has shown that PNs may also be an important substrate for recovery from spinal cord injury (SCI) as they contribute to plastic reorganisation of spinal circuits. The location, inter-segmental projection pattern and sheer number of PNs mean that after SCI, a significant number of them are capable of 'bridging' an incomplete spinal cord lesion. When these properties are combined with the capacity of PNs to activate and coordinate locomotor central pattern generators (CPGs), it is clear they are ideally placed to assist locomotor recovery. Here we summarise the anatomy, organisation and function of PNs in the uninjured spinal cord, briefly outline the pathophysiology of SCI, describe how PNs contribute to recovery of motor function, and finally, we discuss the mechanisms that underlie PN plasticity. We propose there are two major challenges for PN research. The first is to learn more about ways we can promote PN plasticity and manipulate the 'hostile' micro-environment that limits regeneration in the damaged spinal cord. The second is to study the cellular/intrinsic properties of PNs to better understand their function in both the normal and injured spinal cord. This article is part of a Special Issue entitled 'Synaptic Plasticity & Interneurons'.

    Treatment and functional reconstruction atfer central nervous system injury is a major medical and social challenge. An increasing number of researchers are attempting to use neural stem cells combined with artiifcial scaffold materials, such as ifbroin, for nerve repair. However, such approaches are challenged by ethical and practical issues. Amniotic tissue, a clinical waste product, is abundant, and amniotic epithe-lial cells are pluripotent, have low immunogenicity, and are not the subject of ethical debate. We hypothesized that amniotic epithelial cells combined with silk ifbroin scaffolds would be conducive to the repair of spinal cord injury. To test this, we isolated and cultured amniotic epithelial cells, and constructed complexes of these cells and silk ifbroin scaffolds. Implantation of the cell-scaffold complex into a rat model of spinal cord injury resulted in a smaller glial scar in the damaged cord tissue than in model rats that received a blank scaffold, or amniotic epithelial cells alone. In addition to a milder local immunological reaction, the rats showed less inlfammatory cell inifltration at the trans-plant site, milder host-versus-gratf reaction, and a marked improvement in motor function. hTese ifndings conifrm that the transplantation of amniotic epithelial cells combined with silk ifbroin scaffold can promote the repair of spinal cord injury. Silk ifbroin scaffold can provide a good nerve regeneration microenvironment for amniotic epithelial cells.

    2017-04-11

    This review sought to answer the question "What are the barriers and facilitators influencing people's experience of return to work following spinal cord injury?" Studies that met the selection criteria were identified, presented and critically appraised using National Institute for Health and Care Excellence guidelines. Thematic synthesis was completed with studies possessing strong methodological rigor. Synthesis and interpretation involved three stages; coding of primary data; development of descriptive themes reflective of the primary data; and establishment of analytical themes to answer the review question. Data from nine papers were included in the thematic synthesis. Several descriptive themes and three analytical themes were drawn from the data to answer the research question. Analytical themes included: a matrix of personal and environmental factors exists requiring complex navigation in order to create possibilities and opportunities for postinjury employment; the process of seeking or gaining employment shares a reciprocal relationship with the temporal nature of adjustment to spinal cord injury; and there is an intrinsic need for occupational engagement through paid employment. Returning to or gaining employment after spinal cord injury is a fundamentally difficult experience for people. Multiple strategies are required to support the navigation of the process. There is, however, a need in people with spinal cord injury, to be a worker, and with that comes the inherent benefits of being employed. Implications for rehabilitation Returning to work should be a significant focus of spinal cord injury rehabilitation. Employment is both possible and health promoting following spinal cord injury. Multiple strategies are required to support people to navigate the return to work process. It is important to be cognizant of the individual motivations for being a worker and the complexity of the adjustment process. Spinal cord injury centers can provide a

    Spinal cord injury (SCI) can be complete or incomplete. The level of injury in SCI is defined as the most caudal segment with motor function rated at greater than or equal to 3/5, with pain and temperature preserved. The standard neurological classification of SCI provided by the American Spinal Injury Association (ASIA) assigns grades from ASIA A (complete SCI) through ASIA E (normal sensory/motor), with B, C, and D representing varying degrees of injury between these extremes. The most common causes of SCI include trauma (motor vehicle accidents, sports, violence, falls), degenerative spinal disease, vascular injury (anterior spinal artery syndrome, epidural hematoma), tumor, infection (epidural abscess), and demyelinating processes ().

  18. Schwann cells in therapy of spinal cord injuries

    Directory of Open Access Journals (Sweden)

    Izabella Woszczycka-Korczyńska

    2013-07-01

    Full Text Available Schwann cells (SC have a special activity in the repair processes after injury of the nervous system because of the capability of differentiation, migration, proliferation and myelinization of axons. They enhance production of numerous neurotrophic factors, thus creating a permissive environment for axonal regeneration. Experimental studies using SC in neuronal transplants showed that these cells with their basal membrane with adhesion molecules are attractive material for neural prostheses facilitating axon growth. Moreover, SC can produce stable myelin, restoring normal function of the neuron. Transplantations of SC in myelin injury have been used in animal models of multiple sclerosis, Parkinson’s disease, and brain and spinal cord injuries. Because the transplanted SC have no ability to migrate within the normal nervous system, in many experiments SC derived from rat embryos were applied. Such cells migrated through normal nervous tissue and co-operated with host cells, their survival was longer, and myelin was not destroyed in multiple sclerosis. Also, fast recovery of motor activity in injured axons in rat spinal cord was observed, especially after transplantation of SC derived from skin progenitor cells or progenitor cells which have a phenotype characteristic for SC. Many authors have reported early apoptosis of transplanted SC, so a more complex repair strategy is needed that combines SC transplantation with other methods in order to achieve longer survival and optimal functional recovery following spinal cord injury.

    Structural discontinuity in the spinal cord after injury results in a disruption in the impulse conduction resulting in loss of various bodily functions depending upon the level of injury. This article presents a summary of the scientific research employing electrical stimulation as a means for anatomical or functional recovery for patients suffering from spinal cord injury. Electrical stimulation in the form of functional electrical stimulation (FES) can help facilitate and improve upper/lower limb mobility along with other body functions lost due to injury e.g. respiratory, sexual, bladder or bowel functions by applying a controlled electrical stimulus to generate contractions and functional movement in the paralysed muscles. The available rehabilitative techniques based on FES technology and various Food and Drug Administration, USA approved neuroprosthetic devices that are in use are discussed. The second part of the article summarises the experimental work done in the past 2 decades to study the effects of weakly applied direct current fields in promoting regeneration of neurites towards the cathode and the new emerging technique of oscillating field stimulation which has shown to promote bidirectional regeneration in the injured nerve fibres. The present article is not intended to be an exhaustive review but rather a summary aiming to highlight these two applications of electrical stimulation and the degree of anatomical/functional recovery associated with these in the field of spinal cord injury research.

    Spinal cord injury (SCI) is a major focus for stem cell therapy (SCT). However, the science of SCT has not been well matched with an understanding of perspectives of persons with SCI. The online advocacy community is a key source of health information for primary stakeholders and their caregivers. In this study, we sought to characterize the content of SCI advocacy websites with respect to their discussion of SCT and stem cell tourism. We performed a comprehensive analysis of SCI advocacy websites identified through a web search and verified by expert opinion. Two independent researchers coded the information for major themes (e.g., scientific & clinical facts, research & funding, policy, ethics) and valence (positive, negative, balanced, neutral). Of the 40 SCI advocacy websites that met inclusion criteria, 50% (N=20) contained information about SCT. Less than 18% (N=7) contained information on stem cell tourism. There were more than ten times as many statements about SCT with a positive valence (N=67) as with a negative valence (N=6). Ethics-related SCT information comprised 20% (N=37) of the total content; the largest proportion of ethics-related content was devoted to stem cell tourism (80%, N=30 statements). Of those, the majority focused on the risks of stem cell tourism (N=16). Given the still-developing science behind SCT, the presence of cautionary information about stem cell tourism at advocacy sites is ethically appropriate. The absence of stem cell tourism information at the majority of advocacy sites represents a lost educational opportunity.

    2013-01-01

    Full Text Available Cell transplantation, as a therapeutic intervention for spinal cord injury (SCI, has been extensively studied by researchers in recent years. A number of different kinds of stem cells, neural progenitors, and glial cells have been tested in basic research, and most have been excluded from clinical studies because of a variety of reasons, including safety and efficacy. The signaling pathways, protein interactions, cellular behavior, and the differentiated fates of experimental cells have been studied in vitro in detail. Furthermore, the survival, proliferation, differentiation, and effects on promoting functional recovery of transplanted cells have also been examined in different animal SCI models. However, despite significant progress, a “bench to bedside” gap still exists. In this paper, we comprehensively cover publications in the field from the last years. The most commonly utilized cell lineages were covered in this paper and specific areas covered include survival of grafted cells, axonal regeneration and remyelination, sensory and motor functional recovery, and electrophysiological improvements. Finally we also review the literature on the in vivo tracking techniques for transplanted cells.

    Spinal cord injury (SCI) remains a debilitating condition for which there is no cure. In addition to loss of somatic sensorimotor functions, SCI is also commonly associated with impairment of autonomic function. Importantly, cough dysfunction due to paralysis of expiratory muscles in combination with respiratory insufficiency can render affected individuals vulnerable to respiratory morbidity. Failure to clear sputum can aggravate both risk for and severity of respiratory infections, accounting for frequent hospitalizations and even mortality. Recently, epidural stimulation of the lower thoracic spinal cord has been investigated as novel means for restoring cough by evoking expiratory muscle contraction to generate large positive airway pressures and expulsive air flow. This review article discusses available preclinical and clinical evidence, current challenges and clinical potential of lower thoracic spinal cord stimulation (SCS) for restoring cough in individuals with SCI.

    Background The iron catalyzed lipid peroxidation plays an important role in the autodestruction of the injured spinal cord. This study was to detect the antioxidation of melatonin against spinal cord injury (SCI) in rats.Methods Sity Sprague-Dawley rats were randomly divided into four groups: group A (n = 15) for laminectomyanly, group B (n = 15) for laminectomy with SCI, group C (n = 15) for SCI and intraperitoneal injection of a bolus of 100 mg/kg melatonin, and group D (n = 15) for SCI and intraperitoneal injection of saline containing 5% ethanol. The SCI of animal model was made using modified Allen's method on T12. Six rats of each group were sacrificed 4 hours after injury, and the levels of free iron and malondialdehyde (MDA) of the involved spinal cord segments were measured by the bleomycin assay and thiobarbituric acid (TBA) separately. Functional recovery of the spinal cord was assessed by Modified Tarlov's scale and the inclined plane method at 1,3, 7, 14, 21 days after SCI. The histologic changes of the damaged spinal cord were also examined at 7 days after SCl.Results After SCI, the levels of free iron and MDA were increased significantly and the modified Tarlov's score and inclined plane angle decreased significantly in groups B and D. In group C, the Tarlov's score and inclined plane angle were increased significantly at 7, 14 and 21 days, with histological improvement.Conclusion: Melatonin can reduce the level of lipid peroxidation and prevent damage to the spinal cord of rat.

    Full Text Available Vertebral column resection is associated with a risk of spinal cord injury. In the present study, using a goat model, we aimed to investigate the relationship between changes in spinal cord volume and spinal cord injury due to spinal shortening, and to quantify the spinal cord volume per 1-mm height in order to clarify a safe limit for shortening. Vertebral column resection was performed at T10 in 10 goats. The spinal cord was shortened until the somatosensory-evoked potential was decreased by 50% from the baseline amplitude or delayed by 10% relative to the baseline peak latency. A wake-up test was performed, and the goats were observed for two days postoperatively. Magnetic resonance imaging was used to measure the spinal cord volume, T10 height, disc height, osteotomy segment height, and spinal segment height pre- and postoperatively. Two of the 10 goats were excluded, and hence, only data from eight goats were analyzed. The somatosensory-evoked potential of these eight goats demonstrated meaningful changes. With regard to neurologic function, five and three goats were classified as Tarlov grades 5 and 4 at two days postoperatively. The mean shortening distance was 23.6 ± 1.51 mm, which correlated with the d-value (post-pre of the spinal cord volume per 1-mm height of the osteotomy segment (r = 0.95, p < 0.001 and with the height of the T10 body (r = 0.79, p = 0.02. The mean d-value (post-pre of the spinal cord volume per 1-mm height of the osteotomy segment was 142.87 ± 0.59 mm3 (range, 142.19-143.67 mm3. The limit for shortening was approximately 106% of the vertebral height. The mean volumes of the osteotomy and spinal segments did not significantly change after surgery (t = 0.310, p = 0.765 and t = 1.241, p = 0.255, respectively. Thus, our results indicate that the safe limit for shortening can be calculated using the change in spinal cord volume per 1-mm height.

    An injury potential is the direct current potential difference between the site of spinal cord injury and the healthy nerves. Its initial amplitude is a significant indicator of the severity of spinal cord injury, and many cations, such as sodium and calcium, account for the major portion of injury potentials. This injury potential, as wel as injury current, can be modulated by direct current field stimulation;however, the appropriate parameters of the electrical field are hard to define. In this paper, injury potential is used as a parameter to adjust the intensity of electrical stimulation. Injury potential could be modulated to slightly above 0 mV (as the anode-centered group) by placing the anodes at the site of the injured spinal cord and the cathodes at the rostral and caudal sections, or around-70 mV, which is resting membrane potential (as the cathode-centered group) by reversing the polarity of electrodes in the anode-centered group. In addition, rats receiving no electrical stimulation were used as the control group. Results showed that the absolute value of the injury potentials acquired after 30 minutes of electrical stimulation was higher than the control group rats and much lower than the initial absolute value, whether the anodes or the cathodes were placed at the site of injury. This phenomenon il ustrates that by changing the polarity of the electrical field, electrical stimulation can effectively modulate the injury potentials in rats after spinal cord injury. This is also beneficial for the spontaneous repair of the cel membrane and the reduction of cation influx.

    Full Text Available Abstract Severe spinal cord injury (SCI leads to devastating neurological deficits and disabilities, which necessitates spending a great deal of health budget for psychological and healthcare problems of these patients and their relatives. This justifies the cost of research into the new modalities for treatment of spinal cord injuries, even in developing countries. Apart from surgical management and nerve grafting, several other approaches have been adopted for management of this condition including pharmacologic and gene therapy, cell therapy, and use of different cell-free or cell-seeded bioscaffolds. In current paper, the recent developments for therapeutic delivery of stem and non-stem cells to the site of injury, and application of cell-free and cell-seeded natural and synthetic scaffolds have been reviewed.

    A case of a pregnant woman with a subluxation of C-6 on C-7 with acute quadriplegia and sensory loss to the T-10 dermatome is described. Hemodynamic and fetal monitoring during the 3-week period of neurogenic shock resulted in good maternal and fetal outcomes. Pulmonary complications and anesthetic issues are important aspects of the care of these critically ill patients. Major trauma is a common cause of death and disability in young adults and may contribute to as much as 15 percent of nonobstetric maternal deaths. Spinal cord injuries involve young women in 15 percent of cases. The literature is replete with information on the obstetric management of patients with preexisting spinal cord injury (1-4) but there is little on the management and special problems of the pregnant patient with acute spinal cord trauma. We report here the management of a case of acute cord transection accompanied by spinal shock and discuss the specific maternal as well as fetal considerations in this syndrome.

    Full Text Available Loss of respiratory function is one of the leading causes of death following spinal cord injury. Because of this, much work has been done in studying ways to restore respiratory function following SCI - including pharmacological and regeneration strategies. With the emergence of new and powerful tools from molecular neuroscience, new therapeutically relevant alternatives to these approaches have become available, including expression of light sensitive proteins called channelrhodopsins. In this article we briefly review the history of various attempts to restore breathing after C2 hemisection, and focus on our recent work using the activation of light sensitive channels to restore respiratory function after experimental spinal cord injury. We also discuss how such light induced activity can help shed light on the inner workings of the central nervous system respiratory circuitry that controls diaphragmatic function.

    Hyperactive reflexes are commonly observed in patients with spinal cord injury (SCI) but there is a lack of convenient and quantitative characterizations. Patellar tendon reflexes were examined in nine SCI patients and ten healthy control subjects by tapping the tendon using a hand-held instrumented hammer at various knee flexion angles, and the tapping force, quadriceps EMG, and knee extension torque were measured to characterize patellar tendon reflexes quantitatively in terms of the tendon reflex gain (G tr), contraction rate (R c), and reflex loop time delay (t d). It was found that there are significant increases in G tr and R c and decrease in t d in patients with spinal cord injury as compared to the controls (P reflex excitability and muscle contraction dynamics. With proper simplifications, it can potentially be used for quantitative diagnosis and outcome evaluations of hyperreflexia in clinical settings. PMID:25654084

    In this study, we used insulin-like growth factor-1 to induce bone marrow mesenchymal stem cells (MSCs) to differentiate into oligodendrocyte-like cells. Cell surface marker identification showed that they expressed myelin basic protein and galactosylceramide, two specific markers of oligodendrocytes. These cells were transplanted into rats with acute spinal cord injury at T10. At 8 weeks post-implantation, oligodendrocyte-like cells were observed to have survived at the injury site. The critical angle of the inclined plane, and Basso, Beattie and Bresnahan scores were all increased. Furthermore, latencies of motion-evoked and somatosensory-evoked potentials were decreased. These results demonstrate that transplantation of oligodendrocytic-induced MSCs promote functional recovery of injured spinal cord.

    Full Text Available Spinal cord injury (SCI is a serious disease of the center nervous system (CNS. It is a devastating injury with sudden loss of motor, sensory, and autonomic function distal to the level of trauma and produces great personal and societal costs. Currently, there are no remarkable effective therapies for the treatment of SCI. Compared to traditional treatment methods, stem cell transplantation therapy holds potential for repair and functional plasticity after SCI. However, the mechanism of stem cell therapy for SCI remains largely unknown and obscure partly due to the lack of efficient stem cell trafficking methods. Molecular imaging technology including positron emission tomography (PET, magnetic resonance imaging (MRI, optical imaging (i.e., bioluminescence imaging (BLI gives the hope to complete the knowledge concerning basic stem cell biology survival, migration, differentiation, and integration in real time when transplanted into damaged spinal cord. In this paper, we mainly review the molecular imaging technology in stem cell therapy for SCI.

    2013-06-01

    Full Text Available Methylprednisolone is a synthetic glucocorticoid with a potent and long-acting anti-inflammatory, antiallergic and immunosuppressant. Its mechanism of action of methylprednisolone is the result of many cellular changes. Methylprednisolone is used in many diseases, such as rheumatic diseases, autoimmune diseases, allergic, anaphylactic shock, asthma. Methylprednisolone was also used in patients with spinal cord injury, in order to minimize neurological damage. While in the above mentioned fields of medicine is undeniable role of methylprednisolone, whereas its use in the treatment of traumatic spinal cord injury within the last few years raises a lot of controversy, and in most cases, the side effects of its use outweigh the potential benefits.

    Full Text Available Objectives: To assess the test–retest reliability and convergent validity of daily physical activity measures during inpatient spinal cord injury rehabilitation. Design: Observational study. Setting: Two inpatient spinal cord injury rehabilitation centres. Subjects: Participants (n = 106 were recruited from consecutive admissions to rehabilitation. Methods: Physical activity during inpatient spinal cord injury rehabilitation stay was recorded on two days via (1 wrist accelerometer, (2 hip accelerometer if ambulatory, and (3 self-report (Physical Activity Recall Assessment for People with Spinal Cord Injury questionnaire. Spearman’s correlations and Bland–Altman plots were utilized for test–retest reliability. Correlations between physical activity measures and clinical measures (functional independence, hand function, and ambulation were performed. Results: Correlations for physical activity measures between Day 1 and Day 2 were moderate to high (ρ = 0.53–0.89. Bland–Altman plots showed minimal bias and more within-subject differences in more active individuals and wide limits of agreement. None of these three physical activity measures correlated with one another. A moderate correlation was found between wrist accelerometry counts and grip strength (ρ = 0.58 and between step counts and measures of ambulation (ρ = 0.62. Functional independence was related to wrist accelerometry (ρ = 0.70 and step counts (ρ = 0.56, but not with self-report. Conclusion: The test–retest reliability and convergent validity of the instrumented measures suggest that wrist and hip accelerometers are appropriate tools for use in research studies of daily physical activity in the spinal cord injury rehabilitation setting but are too variable for individual use.

    Studies evaluating the Quality of Life of individuals with spinal cord injury using different research tools demonstrate that the Quality of Life scores are considered low both in national and international studies. The objective of this review was to characterize the international scientific production about the most used scales to assess Quality of Life in patients with spinal cord injury. We examined articles on Quality of Life of patients with spinal cord injury published over the last 5 years and indexed in the National Library of Medicine (PUBMED). During this period, 28 articles met the inclusion criteria. Eleven studies were conducted in the United States, five articles were published in Australia, and four in Canada. Brazil, France, Holland, India, Japan, Norway, Singapore and Switzerland contributed with one study each. The scientific articles were published in 13 high impact factor journals. Seven different instruments to assess Quality of Life were used in the studies: Satisfaction with Life Scale, Short Form (36) Health Survey, The Brief Version of the WHO Quality of Life Questionnaire (WHOQOL-BREF), Comprehensive Quality of Life Scale, Life Situation Questionnaire-Revised, Quality of Well-Being Scale and the SF-12® Health Survey. The articles examined underscore the impact of spinal cord injury in the Quality of Life of patients, demonstrating how this condition impairs their lives, mainly socially, but followed by the physical aspects. Despite the studies have different goals they all acknowledge that further studies are necessary in order to determine the Quality of Life of patients with spinal cord injury. Specific instruments should be chosen or developed and validated in order to fulfill this purpose.

    Full Text Available Previous studies have demonstrated that pharmacokinetic behavior of several drugs such as paracetamol, theophylline, and aminoglycosides are significantly altered in spinal cord injured patients. No pharmacokinetic study of amitriptyline has been performed in patients and experimental models of spinal cord injury. Pharmacokinetic parameters of amitriptyline in orally treated rabbits subjected to laminectomy and spinal cord injury compared with those underwent laminectomy alone. Among twenty four male rabbits were included in this study, nine of them subjected to spinal cord injury at the 8 th thoracic level by knife severance method and six rabbits underwent laminectomy alone (sham group and nine rabbits treated as control. All received a single oral dose of amitriptyline (20 mg/kg 24 h after injury. Blood sampling were done at predetermined times to 36 h after drug administration. Amitriptyline concentration in serum samples was determined by high-performance liquid chromatography. Pharmacokinetic parameters including maximum concentration (C max , time to reach maximum concentration (T max , half life, and the area under the curve to last detectable concentration time point (AUC 0-t were directly determined from the concentration-time curve. Maximum concentration was observed at 6.5 h after administration in sham group with a concentration of 439.6 ng/ml, whereas in SCI group T max was at 2.7 h with a concentration of 2763.9 ng/ml. In control group it was 3.3 h and 396 ng/ml, respectively. In SCI group, AUC was 9465.6 ng.h/ml and half life was 6 h and for control group it was 2817.4 ng.h/ml and 6.4 h, respectively. Statistical analysis of data showed that SCI didn′t induce significant changes in amitriptyline pharmacokinetic parameters.

    2013-01-01

    Oligodendrocyte-produced Nogo-A has been shown to inhibit axonal regeneration. Methylprednisolone plays an effective role in treating spinal cord injury, but the effect of methylprednisolone on Nogo-A in the injured spinal cord remains unknown. The present study established a rat model of acute spinal cord injury by the weight-drop method. Results showed that after injury, the motor behavior ability of rats was reduced and necrotic injury appeared in spinal cord tissues, which was accompanied by increased Nogo-A expression in these tissues. After intravenous injection of high-dose methylprednisolone, although the pathology of spinal cord tissue remained unchanged, Nogo-A expression was reduced, but the level was still higher than normal. These findings implicate that methylprednisolone could inhibit Nogo-A expression, which could be a mechanism by which early high dose methylprednisolone infusion helps preserve spinal cord function after spinal cord injury.

    Respiratory neuromuscular impairment severity is known to predict weaning outcome among patients with cervical spinal cord injury; however, the impact of non-neuromuscular complications remains unexplored. This study was to evaluate possible neuromuscular and non-neuromuscular factors that may negatively impact weaning outcome. From September 2002 to October 2012, acute traumatic cervical spinal cord injury patients who had received mechanical ventilation for >48h were enrolled and divided into successful (n=54) and unsuccessful weaning groups (n=19). Various neuromuscular, non-neuromuscular factors and events during the intensive care unit stay were extracted from medical charts and electronic medical records. Variables presenting with a significant difference (pspinal cord injury (C1-3), lower pulse rates, and lower Glasgow Coma Scale score on admission, higher peak blood urea nitrogen, lower trough albumin, and lower trough blood leukocyte counts. Furthermore, unsuccessful weaning patients had a higher incidence of pneumonia, acute respiratory distress syndrome, shock and acute kidney injury during the intensive care unit stay. Multivariate logistic regression analysis revealed acute kidney injury and high level of cervical spinal cord injury were independent risk factors for failure of weaning. Importantly, patients with both risk factors showed a large increase in odds ratio for unsuccessful weaning from mechanical ventilation (pinjury during the intensive care unit stay and high level of cervical spinal injury are two independent risk factors that synergistically work together producing a negative impact on weaning outcome.

    Full Text Available We present the case of a 33-year-old male who sustained a burst fracture D12 vertebrae with spinal cord injury (ASIA impairment scale A and a right mid-diaphysial femoral shaft fracture around 1.5 years back. The patient reported 1.5 years later with a swelling over the right buttock. Arthrotomy revealed serous fluid and fragmented bone debris. The biopsy showed a normal bony architecture with no evidence of infection and malignant cells. Hence, a diagnosis of Charcot′s hip was made. Charcot′s neuroarthropathy of the feet is a well-recognized entity in the setting of insensate feet resulting from causes such as diabetes or spina bifida. Although Charcot′s disease of the hips has been described, it is uncommon in association with spinal cord injury, syphilis and even with the use of epidural injection. The present case highlights the fact that neuroarthropathy of the hip can occur in isolation in the setting of a spinal cord injury, and this can lead to considerable morbidity.

This review provides the epidemiology of TSCI from 1978-2009. It explores the incidence,demography, aetiology of injury, secondary complications, length of stay and provides strategies for improved prevention.Aim: This study summarizes the available data about the epidemiological data of traumatic spinal cord injuries worldwide.Methods: A systematic review in PubMed was conducted.Results: The incidence rates varied greatly among continents. Most of patients with TSCI are young men between 20 to 30 years with road accidents as the leading cause of injury worldwide. The majority of studies reported a high incidence of injury in cervical region.Conclusions: There is a need for improved methods of registration of TSCI particularly from the lack of data from countries of Africa. To clarify regional differences, future epidemiological studies should carry out regional incidence. It is obvious the need for enforcement of laws and also for public awareness campaigns and education programmes.

    Full Text Available Background: Spinal cord injury (SCI is a major clinical condition and research is commonly done to find suitable treatment options. However, there are some degrees of spontaneous recovery after SCI and gender is said to be a contributing factor in recovery, but this is controversial. This study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injury in Wistar Rats. Methods: Spinal cord lesions were made by compressing the cord at T9 level and making a spinal cord contusion. Routine care of each rat was done daily. The LSS scoring system was used to measure the locomotion of these rats and to compare the recovery rate between male and female rats. Results: The results suggested that there was no significant difference between the two sex in recovery. Conclusions: To be female does not seem to be a prognostic factor for recovery after SCI. However, this preliminary study should be repeated in other animals and in larger cohorts.

    The duplication of animal models plays a key role in spinal cord injury research; however, there has been limited study into normal, external force-derived fracture dislocation. This study adopted experimental devices, designed in-house, to construct standardized ventral and dorsal spinal cord injury animal models of 6 g and 17 g falling from a height of 2, 4, and 10 cm, and 15, 30 or 50 g transversal compression on the spinal cord. The results showed that gradual increases in the degree of histopathological injury led to decreased Tarlov and Basso, Beattie and Bresnahan scores for the behavioral test, and increased Ashworth scores for the hind limb. Furthermore, there was a gradual decline in the slope test in the rats with dorsal spinal cord injury that correlated to increases in the falling substance weight or falling height. Similar alterations were observed in the ventral spinal cord injured rats, proportional to the increase in compression weight. Our experimental findings indicate that the standardized experimental rat models of dorsal and ventral spinal cord injury are stable, reliable and reproducible.

    Spinal cord injury (SCI) provokes an inflammatory response that generates substantial secondary damage within the cord but also may contribute to its repair. Anti-inflammatory treatment of human SCI and its timing must be based on knowledge of the types of cells participating in the inflammatory response, the time after injury when they appear and then decrease in number, and the nature of their actions. Using post-mortem spinal cords, we evaluated the time course and distribution of pathological change, infiltrating neutrophils, monocytes/macrophages and lymphocytes, and microglial activation in injured spinal cords from patients who were 'dead at the scene' or who survived for intervals up to 1 year after SCI. SCI caused zones of pathological change, including areas of inflammation and necrosis in the acute cases, and cystic cavities with longer survival (Zone 1), mantles of less severe change, including axonal swellings, inflammation and Wallerian degeneration (Zone 2) and histologically intact areas (Zone 3). Zone 1 areas increased in size with time after injury whereas the overall injury (size of the Zones 1 and 2 combined) remained relatively constant from the time (1-3 days) when damage was first visible. The distribution of inflammatory cells correlated well with the location of Zone 1, and sometimes of Zone 2. Neutrophils, visualized by their expression of human neutrophil alpha-defensins (defensin), entered the spinal cord by haemorrhage or extravasation, were most numerous 1-3 days after SCI, and were detectable for up to 10 days after SCI. Significant numbers of activated CD68-immunoreactive ramified microglia and a few monocytes/macrophages were in injured tissue within 1-3 days of SCI. Activated microglia, a few monocytes/macrophages and numerous phagocytic macrophages were present for weeks to months after SCI. A few CD8(+) lymphocytes were in the injured cords throughout the sampling intervals. Expression by the inflammatory cells of the oxidative

    In reports from the UK and New Zealand, it is noted that the incidence of rugby injuries to the cervical spinal cord has dropped and that the percentage of players injured in the tackle has similarly decreased. In contrast, this does not appear to be the pattern in South Africa and an analysis has therefore been made of 40 rugby players sustaining injuries to the spinal cord during the period 1985 to 1989. The radiological appearances on admission have been correlated with the circumstances of injury, associated orthopaedic injuries and neurological deficits. The tackle was responsible for the majority of injuries, causing more than the scrum. Tackles were also responsible for more cases of complete, permanent quadriplegia than the scrum. The commonest cause of injury in players being tackled was the high tackle around the neck, while the commonest cause of injury in players making the tackle was the dive tackle. This survey has shown that the tackle is now the major cause of spinal cord injury in South African rugby, in contrast to earlier analyses in which the scrum was identified as the most common cause.

    Abstract Spinal cord injury (SCI) often results in irreversible and permanent neurological deficits and long-term disability. Vasospasm, hemorrhage, and loss of microvessels create an ischemic environment at the site of contusive or compressive SCI and initiate the secondary injury cascades leading to progressive tissue damage and severely decreased functional outcome. Although the initial mechanical destructive events cannot be reversed, secondary injury damage occurs over several hours to weeks, a time frame during which therapeutic intervention could be achieved. One essential component of secondary injury cascade is the reduction in spinal cord blood flow with resultant decrease in oxygen delivery. Our group has recently shown that administration of fluorocarbon (Oxycyte) significantly increased parenchymal tissue oxygen levels during the usual postinjury hypoxic phase, and fluorocarbon has been shown to be effective in stroke and head injury. In the current study, we assessed the beneficial effects of Oxycyte after a moderate-to-severe contusion SCI was simulated in adult Long-Evans hooded rats. Histopathology and immunohistochemical analysis showed that the administration of 5 mL/kg of Oxycyte perfluorocarbon (60% emulsion) after SCI dramatically reduced destruction of spinal cord anatomy and resulted in a marked decrease of lesion area, less cell death, and greater white matter sparing at 7 and 42 days postinjury. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining showed a significant reduced number of apoptotic cells in Oxycyte-treated animals, compared to the saline group. Collectively, these results demonstrate the potential neuroprotective effect of Oxycyte treatment after SCI, and its beneficial effects may be, in part, a result of reducing apoptotic cell death and tissue sparing. Further studies to determine the most efficacious Oxycyte dose and its mechanisms of protection are warranted. PMID:24025081

    Injury potential, a direct current potential difference between normal section and the site of injury, is a significant index of spinal cord injury. However, its importance has been ignored in the studies of spinal cord electrophysiology and electrical stimulation (ES). In this paper, compensation for injury potential is used as a criterion to adjust the intensity of stimulation. Injury potential is modulated to slightly larger than 0 mV for 15, 30 and 45 minutes immediately after injury by placing the anodes at the site of injury and the cathodes at the rostral and caudal section. Injury potentials of all rats were recorded for statistical analysis. Results show that the injury potentials acquired after ES are higher than those measured from rats without stimulation and much lower than the initial amplitude. It is also observed that the stimulating voltage to keep injury potential be 0 remain the same. This phenomenon suggests that repair of membrane might occur during the period of stimulation. It is also suggested that a constant voltage stimulation can be applied to compensate for injury potential.

    Image guided intercostal blocks are commonly performed and considered relatively safe. Chemical denervation is commonly used in clinical practice for treatment of chronic non-cancer associated pain. To report a case of spinal cord injury resulting from fluoroscopically guided intercostal blocks with phenol. Case report. Inpatient hospital service. RESULTS/CASE REPORTS: A 53 year-old women was transferred from her local facility for acute onset of lower extremity paresis beginning shortly after right intercostal nerve injections of 2 mL of preservative-free phenol at the T7, 8, 9 levels. She had previous intercostal blocks for chronic right-sided mid thoracic/abdominal pain every 3 months for at least one year without sequelae. Within 20 minutes of the injection, she developed a sensation of right leg weakness and heaviness. Over several hours she developed worsening right leg weakness, and then left leg weakness, followed by urinary retention. Admission examination revealed severe right greater than left leg weakness, right lower extremity hyperesthesia to T10, absent lower extremity reflexes, and bilateral extensor plantar responses. Magnetic resonance imaging (MRI) of the entire spine demonstrated extensive T2/DWI hyperintensity in the central spinal cord from T1 to L1 with mild cord enlargement and enhancement at T7-9 (sites of injection). Extensive serum and cerebrospinal fluid (CSF) evaluation did not show any evidence of an infectious, inflammatory, or metabolic cause to her myelopathy. Repeat MRI of the entire spine demonstrated near complete resolution of the T2 signal abnormality. One month after presentation, despite radiographic improvement, the patient showed some clinical improvement, but remained walker dependent and with neurogenic bowel and bladder. This report describes a single case report. This case offers several lessons for a pain specialist including 1) the potential for a neurologic catastrophe (spinal cord injury) from aqueous neurolytic

    Full Text Available Definitions of spinal cord injury agree in the consequences of that injury is the loss in varying degrees of autonomic function; this will cause a change in the lifestyle of patients and their families.In the spinal injury, the priority is the recovery or maintenance of vital organ functions, the physical stabilization for people. Later, the priority here is the rehabilitation and adaptation. This should be integrated at all levels, physical, psychological and social. Confrontation is, by Callista Roy, a important variable for understanding the effect of stress on health and disease, health maintenance or recovery. The way, that the patients have to confront the disease, are the confrontation strategies. They are defined as thoughts and actions that persons put in place to deal with adverse changes. They are grouped into 3 categories: problems, emotions and avoidance.There are others factors that influence in the use of strategies, between them the personality. According to Eysenck this is determined by the functional interaction of four factors: cognitive (intelligence, conative (character, affective (temperament and somatic (construction. With this study we want to know the factors that influence in the confrontation of the spinal cord injury and to analyze the possible relation between them, and to be able to elaborate particular tools, on the most determinant factors, to obtain an effective confrontation about this type of disease.

    Retrospective analysis of civilians with spinal cord injuries (SCIs) due to terror explosions. To analyze and describe the clinical characteristics and rehabilitation outcomes of civilians with SCI due to explosions admitted for in-patient rehabilitation from 2000-2004. SCI rehabilitation service, Tel Hashomer, Israel. Retrospective chart review. Civilians with SCI due to terror-related gunshot wounds (GSWs) served as a control group. Eleven civilians with SCI caused by penetrating atypical foreign objects (PAFOs) and eight with GSWs were identified. The male-to-female ratio was approximately 2:1. Foreign objects were present within the spinal canal in seven patients, causing bone injury without canal penetration in three, and one patient had both bone injury and canal penetration. The most common level of injury was thoracic. Seven had complete motor SCI. Three individuals improved in American Spinal Injury Association status: one individual improved from B to C (cervical); one from C to D (thoracic); and the third from D to E (lumbar). Despite the similar acute hospital length of stay and functional independence measure (FIM) scores on admission, the PAFO group had a shorter rehabilitation length of stay with higher FIM scores and higher FIM efficiency at discharge. Although the pathophysiology of PAFO blast injuries is similar to the high-velocity GSWs or the high-energy military munition injuries, better rehabilitation outcomes were seen, with slightly higher FIM efficiency and efficacy at discharge. This result is likely to be caused by less neurological tissue damage at impact.

    Full Text Available Background/Aims: Dexmedetomidine has beneficial effects on ischemia reperfusion (I/R injury to the spinal cord, but the underlying mechanisms are not fully understood. This study investigated the effects and possible mechanisms of dexmedetomidine on blood-spinal cord barrier (BSCB disruption induced by spinal cord I/R injury. Methods: Rats were intrathecally pretreated with dexmedetomidine or PBS control 30 minutes before undergoing 14-minute occlusion of aortic arch. Hind-limb motor function was assessed using Tarlov criteria, and motor neurons in the ventral gray matter were counted by histological examination. The permeability of the BSCB was examined using Evans blue (EB as a vascular tracer. The spinal cord edema was evaluated using the wet-dry method. The expression and localization of matrix metalloproteinase-9 (MMP-9, Angiopoietin-1 (Ang1 and Tie2 were assessed by western blot, real-time polymerase chain reaction, and immunofluorescence. Results: Intrathecal preconditioning with dexmedetomidine minimized the neuromotor dysfunction and histopathological deficits, and attenuated EB extravasation after spinal cord I/R injury. In addition, dexmedetomidine preconditioning suppressed I/R-induced increase in MMP-9. Finally, Dexmedetomidine preconditioning enhanced the Ang1-Tie2 system activity after spinal cord I/R injury. Conclusions: Dexmedetomidine preconditioning stabilized the BSCB integrity against spinal cord I/R injury by inhibition of MMP-9, and enhancing the Ang1-Tie2 system.

    The scarring response after a penetrant central nervous system injury results from the interaction between invading leptominingeal/pericyte-derived ifbroblasts and endogenous reactive astrocytes about the wound margin. Extracellular matrix and scar-derived axon growth inhibitory mole-cules ifll the lesion site providing both a physical and chemical barrier to regenerating axons. Dec orin, a small leucine-rich chondroitin-dermatan sulphate proteoglycan expressed by neurons and astrocytes in the central nervous system, is both anti-ifbrotic and anti-inlfammatory and attenu-ates the formation and partial dissolution of established and chronic scars. Here, we discuss the potential of using Decorin to antagonise scarring in the central nervous system.

    After spinal cord injury (SCI) reorganization of spinal cord circuits occur both above and below the spinal lesion. These functional changes can be determined by assessing electrophysiological recording. We aimed at investigating the trigemino-cervical reflex (TCR) and trigemino-spinal reflex (TSR) responses after traumatic SCI. TCR and TSR were registered after stimulation of the infraorbital nerve from the sternocleidomastoid, splenius, deltoid, biceps and first dorsal interosseous muscles in 10 healthy subjects and 10 subjects with incomplete cervical SCI. In the control subjects reflex responses were registered from the sternocleidomastoid, and splenium muscles, while no responses were obtained from upper limb muscles. In contrast, smaller but clear short latency EMG potentials were recorded from deltoid and biceps muscles in about half of the SCI patients. Moreover, the amplitudes of the EMG responses in the neck muscles were significantly higher in patients than in control subjects. The reflex responses are likely to propagate up the brainstem and down the spinal cord along the reticulospinal tracts and the propriospinal system. Despite the loss of corticospinal axons, synaptic plasticity in pre-existing pathways and/or formation of new circuits through sprouting processes above the injury site may contribute to the findings of this preliminary study and may be involved in the functional recovery. Trigemino-cervical-spinal reflexes can be used to demonstrate and quantify plastic changes at brainstem and cervical level following SCI.

    Spinal cord injury (SCI) often results in some form of paralysis. Recently, SCI therapy has been focused on preventing secondary injury to reduce both neuroinflammation and lesion size so that functional outcome after an SCI may be improved. Previous studies have shown that adenosine receptors (AR) are a major regulator of inflammation after an SCI. The current study was performed to examine the effect of caffeine, a pan-AR blocker, on spontaneous functional recovery after an SCI. Animals were assigned into 3 groups randomly, including sham, PBS and caffeine groups. The rat SCI was generated by an NYU impactor with a 10 g rod dropped from a 25 mm height at thoracic 9 spinal cord level. Caffeine and PBS were injected daily during the experiment period. Hind limb motor function was evaluated by the Basso, Beattie, Bresnahan (BBB) locomotor rating scale at 1 week and 4 weeks after the SCI. Spinal cord segments were collected after final behavior evaluation for morphological analysis. The tissue sparing was evaluated by luxol fast blue staining. Immunofluorescence stain was employed to assess astrocyte activation and neurofilament positioning, while microglia activation was examined by immunohistochemistry stain.The results showed that spontaneous functional recovery was blocked after the animals were subjected caffeine daily. Moreover, caffeine administration increased the demyelination area, promoted astrocyte and microglia activation and decreased the quantity of neurofilaments. These findings suggest that the neurotoxicity effect of caffeine may be associated with the inhibition of neural repair and the promotion of neuroinflammation.

    Objective: To observe the effect of quercetin on experimental spinal cord injury (SCI) in rats.Methods: Sixty Sprague-Dawley rats were randomly divided into four groups: Group A only for laminectomy,Group B for laminectomy with SCI, Group C for SCI and intraperitoneal injection with a bolus of 200 mg/kg quercetin and Group D for SCI and intraperitoneal injection of saline. SCI model was made by using modified Allen's method on T12. Six rats of each group were killed at4 h after injury and the levels of free iron and malondialdehyde (MDA) of the involved spinal cord segments were measured by bleomycin and thiobarbituric acid (TBA) assays separately. The recovery of hind limb function was assessed by Modified Tarlov's scale and inclined plane method at 7 d,14 d and 21 d after SCI. The histological changes of the damaged spinal cord were also examined at 7 d after SCI.Results: After SCI, the levels of free iron and MDA were significantly increased in Groups B and D, while not in Group C. The Modified Tarlov's score and the inclined plane angles were significantly decreased in Groups B, C and D. The histological findings were not improved.Conclusions: After SCI, quercetin can reduce the level of lipid peroxidation, but not improve recovery of function.

    Spinal Cord Injury (SCI) is a devastating situation. Spinal Cord Injury affects functional, psychological and socioeconomic aspects of patients' lives. The ability to accomplish and explicate the one's own and other's feelings and emotions to spread over appropriate information for confirming thoughts and actions is defined as emotional intelligence (EI). The goal of this study was to evaluate depression and EI in SCI patients in comparison with healthy subjects. One-hundred-ten patients with SCI and 80 healthy subjects between Aug 2014 and Aug 2015 were enrolled. The study was conducted in Imam Hospital, Tehran, Iran. All participants were asked to fill valid and reliable Persian version Emotional Quotient inventory (EQ-i) and Beck Depression Inventory (BDI). All data were analyzed using SPSS. Data were presented as Mean±SD for continuous or frequencies for categorical variables. Continuous variables compared by means of independent sample t-test. P-values less than 0.05 were considered as significant. Mean age of patients was 28.7 and mean age of controls was 30.2 yr. Spinal cord injury in 20 (18.3%) were at cervical level, in 83 (75.4%) were thoracic and in 7 (6.3%) were lumbar. Mean values of independence, stress tolerance, self-actualization, emotional Self-Awareness, reality testing, Impulse Control, flexibility, responsibility, and assertiveness were significantly different between cases and controls. Mean values of stress tolerance, optimism, self-regard, and responsibility were significantly different between three groups with different injury level. Most scales were not significantly different between male and female cases. Emotional intelligence should be considered in SCI cases as their physical and psychological health is affected by their illness.

    The Purpose of this review is to outline and explain the therapeutic use of electrical spinal cord stimulation (SCS) for modification of spinal motor output. Central functional stimulation provides afferent input to posterior root neurons and is applied to improve volitional movements, posture and their endurance, control spasticity, and improve bladder function or perfusion in the lower limbs. Clinical accomplishments strongly depend on each individual's physiological state and specific methodical adaptation to that physiological state. Effectiveness of this neuromodulory technique for changing motor control after spinal cord injury (SCI) continues to be explored along with the underlying mechanisms of its effect in people with complete and incomplete spinal cord injuries. There are extensive studies of tonic and rhythmical activity elicited from the lumbar cord as well as data demonstrating augmentation of residual volitional activity. Recent studies have focused on verifying if and how SCS can modify features of neurocontrol in ambulatory spinal cord patients. In this review, we emphasize recent publications of research revealing that SCS can substitute for the reduced brain drive for control of excitability in people with SCI. Artificially replacing diminished or lost brain control over the spinal cord has limitations. A fundamental requirement for successful SCS application is analysis of each individual's residual postinjury neural function. This will allow a better understanding of the physiological interactions between SCS and spinal cord motor control below injury and provide criteria for its application. Finally, the publication of both successful and failed applications of SCS will be crucial for gaining future progress.

    To examine the prevalence of joint contractures in the upper limb and association with voluntary strength, innervation status, functional status, and demographics in a convenience sample of individuals with cervical spinal cord injury to inform future prospective studies. Cross-sectional convenience sampled pilot study. Department of Veterans Affairs Research Laboratory. Thirty-eight participants with cervical level spinal cord injury. Not applicable. Contractures were measured with goniometric passive range of motion. Every joint in the upper extremity was evaluated bilaterally. Muscle strength was measured with manual muscle testing. Innervation status was determined clinically with surface electrical stimulation. Functional independence was measured with the Spinal Cord Independence Measure III (SCIM-III). Every participant tested had multiple joints with contractures and, on average, participants were unable to achieve the normative values of passive movement in 52% of the joints tested. Contractures were most common in the shoulder and hand. There was a weak negative relationship between percentage of contractures and time post-injury and a moderate positive relationship between percentage of contractures and age. There was a strong negative correlation between SCIM-III score and percentage of contractures. Joint contractures were noted in over half of the joints tested. These joint contractures were associated with decreased functional ability as measured by the SCIM-III. This highlights the need the need for detailed evaluation of the arm and hand early after injury as well as continued monitoring of joint characteristics throughout the life course of the individual with tetraplegia.

    Spinal cord injury is one of the most devastating incidents that can occur to an individual as it results in life being suddenly, dramatically, radically and long lastingly changed. Different studies show that a spinal cord injury is a stressful event, leading to physiological dependence, psychological and social illness and suffering, although the situation tends to improve over time. This study is a part of a larger longitudinal study. The aim of this study was to explore and interpret 10 individuals' experiences in connection with their acute and unexpected spinal cord injury. This qualitative study has a descriptive and explorative design and is a part of a larger study. A phenomenological hermeneutic approach inspired by Ricoeur was used to extract the meaningful content of the patients' narratives. In this study, the findings revealed three main themes: (I) 'the incomprehensible shock', (II) 'brave survivors' and (III) 'miracles, luck or coincidences?' The incomprehensible spinal cord injury was often experienced as a dramatic and unexpected shock in the middle of a pleasant occasion, and every participant felt immediately overwhelmed by emotional suffering, such as despair and panic, but also anxiety, confusion, sorrow, guilt, shame, fear, aggression or depression at the moment of injury. Some individuals immediately understood that they had become completely paralysed and that something was seriously wrong with their body. Many also experienced guilt or shame because of choices or decisions made immediately before the injury. Several of the narratives were illuminating participants that had been brave survivors and heroes and saved others (passengers or friends) during the injury, by preventing the car form driving out or by softening the fall of co-passengers, which also entailed more serious injuries to themselves. However, the fact of having survived was experienced as 'being lucky, after all'. They all repeatedly reflected on the accident, and their

    This study was initiated due to an NIH "Facilities of Research-Spinal Cord Injury" contract to support independent replication of published studies. Transient blockage of the CD11d/CD18 integrin has been reported to reduce secondary neuronal damage as well as to improve functional recovery after spinal cord injury (SCI) in rats. The purpose of this study was to determine whether treatment with an anti-CD11d monoclonal antibody (mAb) would improve motor performance, reduce pain and histopathological damage in animals following clip-compression injury as reported. Adult male Wistar rats (250g) were anesthetized with isoflurane, and the T12 spinal cord exposed by T10 and T11 dorsal laminectomies followed by a 60s period of clip compression utilizing a 35g clip. Control animals received an isotype-matched irrelevant antibody (1B7) while the treated group received the anti-CD11d mAb (217L; 1.0mg/kg) systemically. Open-field locomotion and sensory function were assessed and animals were perfusion-fixed at twelve weeks after injury for quantitative histopathological analysis. As compared to 1B7, 217L treated animals showed an overall non-significant trend to better motor recovery. All animals showed chronic mechanical allodynia and anti-CD11d mAb treatment did not significantly prevent its development. Histopathological analysis demonstrated severe injury to gray and white matter after compression with a non-significant trend in anti-CD11d protection compared to control animals for preserved myelin. Although positive effects with the anti-CD11d mAb treatment have been reported after compressive SCI, it is suggested that this potential treatment requires further investigation before clinical trials in spinal cord injured patients are implemented.

    Full Text Available Masaki Ueno, Toshihide YamashitaDepartment of Molecular Neuroscience, Graduate School of Medicine, Osaka University, 2-2 Yamadaoka, Suita-shi, Osaka 565-0871, JapanAbstract: Axonal regeneration does not occur easily after an adult central nervous system (CNS injury. Various attempts have partially succeeded in promoting axonal regeneration after the spinal cord injury (SCI. Interestingly, several recent therapeutic concepts have emerged from or been tightly linked to the researches on brain development. In a developing brain, remarkable and dynamic axonal elongation and sprouting occur even after the injury; this finding is essential to the development of a therapy for SCI. In this review, we overview the revealed mechanism of axonal tract formation and plasticity in the developing brain and compare the differences between a developing brain and a lesion site in an adult brain. One of the differences is that mature glial cells participate in the repair process in the case of adult injuries. Interestingly, these cells express inhibitory molecules that impede axonal regeneration such as myelin-associated proteins and the repulsive guidance molecules found originally in the developing brain for navigating axons to specific routes. Some reports have clearly elucidated that any treatment designed to suppress these inhibitory cues is beneficial for promoting regeneration and plasticity after an injury. Thus, understanding the developmental process will provide us with an important clue for designing therapeutic strategies for recovery from SCI.Keywords: development, regeneration, spinal cord injury

  18. Psychological stress as a modulator of functional recovery following spinal cord injury

    2014-04-01

    Full Text Available There is strong evidence indicating that the social environment triggers changes to the psychological stress response and glucocorticoid receptor function. Considerable literature links the subsequent changes in stress resiliency to physical health. Here, converging evidence for the modulatory role of chronic psychological stress in the recovery process following spinal cord injury (SCI is presented. Despite the considerable advances in spinal cord injury research, we are still unable to identify the causes of variability in patients’ recovery following injury. We propose that individuals’ past and present life experiences (in the form of stress exposure may significantly modulate patients’ outcome post SCI. We propose a theoretical model to explain the negative impact of chronic psychological stress on physical and psychological recovery. The stress experienced in life prior to SCI and also as a result of the traumatic injury, could compromise glucocorticoid receptor sensitivity and function, and contribute to high levels of inflammation and apoptosis post SCI, decreasing the tissue remaining at the injury site and undermining recovery of function. Both stress induced glucocorticoid resistance and stress induced epigenetic changes to the glucocorticoid receptor can modulate the NF-кB regulated inflammatory pathways and the Bcl-2 regulated apoptosis pathways. This model not only contributes to the theoretical understanding of the recovery process following injury, but also provides concrete testable hypotheses for future studies.

    Pressure ulcers in spinal cord injury represent a challenging problem for patients, their caregivers, and their physicians. They often lead to recurrent hospitalizations, multiple surgeries, and potentially devastating complications. They present a significant cost to the healthcare system, they require a multidisciplinary team approach to manage well, and outcomes directly depend on patients' education, prevention, and compliance with conservative and surgical protocols. With so many factors involved in the successful treatment of pressure ulcers, an update on their comprehensive management in spinal cord injury is warranted. Current concepts of local wound care, surgical options, as well as future trends from the latest wound healing research are reviewed to aid medical professionals in treating patients with this difficult problem.

  1. Neural stem cell transplantation in the repair of spinal cord injury

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Neural stem cells are a pronising candidate for neural transplantation aimed at neural cell replacement and repair of the damaged host central nervous system (CNS). Recent studies using neural stem cells have shown that implanted neural stem cells can effectively incorporate into the damaged CNS and differentiate into neurons, astrocytes, and oligodendrocytes. The recent explosion in the field of neural stem cell research has provided insight into the inductive factors influencing neural stem cell differentiation and may yield potential therapies for several neurological disorders, including spinal cord injury. In this review, we summarize recent studies involving neural stem cell biology in both rodents and humans. We also discuss unique advantages and possible mechanisms of using neural stem cell trans plantation in the repair of spinal cord injury.

    Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups: control, surgical control, spinal cord injury, and one cell-treated lesion group. Mononuclear cells from umbilical cord blood of human male neonates were transplanted in two experiments: a) 1 h after surgery, into the injury site at a concentration of 5 x 10{sup 6} cells diluted in 10 µL 0.9% NaCl (N = 8-10 per group); b) into the cisterna magna, 9 days after lesion at a concentration of 5 x 10{sup 6} cells diluted in 150 µL 0.9% NaCl (N = 12-14 per group). The transplanted animals were immunosuppressed with cyclosporin-A (10 mg/kg per day). The BBB scale was used to evaluate motor behavior and the injury site was analyzed with immunofluorescent markers to label human transplanted cells, oligodendrocytes, neurons, and astrocytes. Spinal cord injury rats had 25% loss of cord tissue and cell treatment did not affect lesion extension. Transplanted cells survived in the injured area for 6 weeks after the procedure and both transplanted groups showed better motor recovery than the untreated ones (P < 0.05). The transplantation of mononuclear cells from human umbilical cord blood promoted functional recovery with no evidence of cell differentiation.

    Full Text Available Approximately 500 South Africans, mainly young people,sustain a spinal cord injury every year leading to severe lifetime physical disabilities. With advances in medicine and assistive technology, these young people are able to reach adulthood. The physical, social and  emotional adjustments, which determine the eventual successful outcome following injury, vary considerably from person to person. Some make satisfactory adjustments whereas others remain chronically distressed.This study aimed to determine the impact of SCI on youth in community settings after discharge from rehabilitation.  A qualitative approach, that utilised face-to-face interviews and focus group methods of data collection, was used. Data were drawn from ten participants selected at Conradie Spinal Rehabilitation Unit, using purposive sampling. Audiotape recorded interviews were transcribed verbatim. Strong themes that ran through the data were identified. The results of the study revealed that spinal cord injury impacts on more than just the physical capabilities of an individual. Participants identified issues such as social identity, intrapersonal and interpersonal factors, social support and employment opportunities as having a major impact on their lives once back in the community.  It is  recommended that rehabilitation professionals include issues such as identity and psychosocial adjustment into their health promotion interventions.

    The current study aimed to investigate the effect of lycopene on the blood-spinal cord barrier (BSCB) after spinal cord injury (SCI) in a mouse model. Lycopene inhibited lipid peroxidation and oxidative DNA damage as a highly efficient antioxidant and free radical scavenger. Lycopene (4 mg/kg/d) was administrated immediately following SCI. The permeability of the BSCB and water content in the spinal cord tissue were evaluated. Additionally, levels of expression of tight junction proteins and heme oxygenase-1 (HO-1) were determined with Western blotting. An enzyme-linked immunosorbent assay analysis of spinal cord tissue homogenates was performed 48 h after SCI to evaluate the expression of inflammation-related cytokines. In addition, recovery of motor function was assessed 1 d, 2 d, 5 d, 10 d, and 15 d after SCI using the Basso Mouse Scale to score locomotion. Compared to the group with an untreated SCI, mice with an SCI treated with lycopene had significantly reduced spinal cord tissue water content and BSCB permeability. Furthermore, motor function of mice with an SCI was also greatly improved by lycopene administration. The expression of the proinflammatory factors TNF-α and NF-kB increased markedly 48 h after SCI, and their upregulation was significantly attenuated by lycopene treatment. The expression of molecules that protect tight junctions, zonula occluden-1 and claudin-5, was upregulated by lycopene treatment after SCI. Taken together, these results clearly indicate that lycopene attenuated SCI by promoting repair of the damaged BSCB, so lycopene is a novel and promising treatment for SCI in humans.

    Dopamine (DA) neurons in the mammalian central nervous system are thought to be restricted to the brain. DA-mediated regulation of urinary activity is considered to occur through an interaction between midbrain DA neurons and the pontine micturition center. Here we show that DA is produced in the rat spinal cord and modulates the bladder reflex. We observed numerous tyrosine hydroxylase (TH)(+) neurons in the autonomic nuclei and superficial dorsal horn in L6-S3 spinal segments. These neurons are dopamine-β-hydroxylase (DBH)(-) and some contain detectable dopamine decarboxylase (DDC), suggesting their capacity to produce DA. Interestingly, following a complete thoracic spinal cord injury (SCI) to interrupt supraspinal projections, more TH(+) neurons emerged in the lumbosacral spinal cord, coincident with a sustained, low level of DA expression there and a partially recovered micturition reflex. Non-selective blockade of spinal DA receptors reduced bladder activity whereas activation of spinal D2-like receptors increased bladder activity and facilitated voiding. Additionally, depletion of lumbosacral TH(+) neurons with 6-hydroxydopamine (6-OHDA) decreased bladder non-voiding contractions and voiding efficiency. Furthermore, injecting the transsynaptic neuronal tracer pseudorabies virus (PRV) into the bladder detrusor labeled TH(+) cells in the lumbosacral cord, confirming their involvement in spinal micturition reflex circuits. These results illustrate that DA is synthesized in the rat spinal cord; plasticity of lumbosacral TH(+) neurons following SCI may contribute to DA expression and modulate the spinal bladder reflex. Thus, spinally-derived DA and receptors could be a novel therapeutic target to improve micturition recovery after SCI. Published by Elsevier Inc.

    Objective: To observe dynamic changes of intracellular calcium ([Ca2+]i) after spinal cord injury, and to study the relationship between the changes of [Ca2+]i and the functional damage of the spinal cord.   Methods: The rats were subjected to a spinal cord contusion by using a modified Allens method. The [Ca2+]i in the injured segment of the spinal cord was measured by the technique of La3+ blockage and atomic absorption spectroscopy at 1, 4, 8, 24, 72, and 168 hours after injury. The motor function on the inclined plane was measured at the same time.   Results: The spinal cord [Ca2+]i increased significantly (P<0.05 or P<0.01) after spinal cord injury. There was a significant correlation (P<0.05) between the changes of [Ca2+]i and the motor function.   Conclusions: [Ca2+]i overload may play an important role in the pathogenesis of spinal cord injury.

  11. Extrinsic and Intrinsic Regulation of Axon Regeneration by MicroRNAs after Spinal Cord Injury

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Spinal cord injury is a devastating disease which disrupts the connections between the brain and spinal cord, often resulting in the loss of sensory and motor function below the lesion site. Most injured neurons fail to regenerate in the central nervous system after injury. Multiple intrinsic and extrinsic factors contribute to the general failure of axonal regeneration after injury. MicroRNAs can modulate multiple genes’ expression and are tightly controlled during nerve development or the injury process. Evidence has demonstrated that microRNAs and their signaling pathways play important roles in mediating axon regeneration and glial scar formation after spinal cord injury. This article reviews the role and mechanism of differentially expressed microRNAs in regulating axon regeneration and glial scar formation after spinal cord injury, as well as their therapeutic potential for promoting axonal regeneration and repair of the injured spinal cord.

    Ludwig Guttmann was a pioneer of the idea of rehabilitation for victims of spinal cord injury. He looked beyond the physical survival of his patients, to their re-integration into a social life worth living. While the International Stoke Mandeville Games are fairly well known to the general public as a gathering for physically handicapped athletes, less is known about the man who helped start the movement. On the occasion of the recent Sydney 2000 Paralympics, this paper reviews the contribution of Ludwig Guttmann, who introduced sport into the life of paralyzed patients.

    2014-01-01

    Full Text Available Brain and spinal cord are implicated in incidences of two of the most severe injuries of central nervous system (CNS. Traumatic brain injury (TBI is a devastating neurological deficit involving primary and secondary injury cascades. The primary and secondary mechanisms include complex consequences of activation of proinflammatory cytokines, cerebral edema, upregulation of NF-κβ, disruption of blood-brain barrier (BBB, and oxidative stress. Spinal cord injury (SCI includes primary and secondary injury cascades. Primary injury leads to secondary injury in which generation of free radicals and oxidative or nitrative damage play an important pathophysiological role. The indoleamine melatonin is a hormone secreted or synthesized by pineal gland in the brain which helps to regulate sleep and wake cycle. Melatonin has been shown to be a versatile hormone having antioxidative, antiapoptotic, neuroprotective, and anti-inflammatory properties. It has a special characteristic of crossing BBB. Melatonin has neuroprotective role in the injured part of the CNS after TBI and SCI. A number of studies have successfully shown its therapeutic value as a neuroprotective agent in the treatment of neurodegenerative diseases. Here in this review we have compiled the literature supporting consequences of CNS injuries, TBI and SCI, and the protective role of melatonin in it.

    Data-driven discovery in complex neurological disorders has potential to extract meaningful syndromic knowledge from large, heterogeneous data sets to enhance potential for precision medicine. Here we describe the application of topological data analysis (TDA) for data-driven discovery in preclinical traumatic brain injury (TBI) and spinal cord injury (SCI) data sets mined from the Visualized Syndromic Information and Outcomes for Neurotrauma-SCI (VISION-SCI) repository. Through direct visualization of inter-related histopathological, functional and health outcomes, TDA detected novel patterns across the syndromic network, uncovering interactions between SCI and co-occurring TBI, as well as detrimental drug effects in unpublished multicentre preclinical drug trial data in SCI. TDA also revealed that perioperative hypertension predicted long-term recovery better than any tested drug after thoracic SCI in rats. TDA-based data-driven discovery has great potential application for decision-support for basic research and clinical problems such as outcome assessment, neurocritical care, treatment planning and rapid, precision-diagnosis.

    Previous research had reported transcription factors Nanog expressed in pluripotent embryonic stem cells (ESCS) that played an important role in regulating the cell proliferation. Nanog levels are frequently elevated in ESCS, but the role in the spinal cord was not clear. To examine the biological relevance of Nanog, we studied its properties in spinal cord injury model. The expression of Nanog and PCNA was gradually increased and reached a peak at 3 day by western blot analysis. The expression of Nanog was further analyzed by immunohistochemistry. Double immunofluorescent staining uncovered that Nanog can co-labeled with PCNA and GFAP in the spinal cord tissue. In vitro, Nanog can promote the proliferation of astrocyte cell by Fluorescence Activating Cell Sorter (FACS) and CCK8. Meanwhile, the cell-cycle protein CDK6 could interact with Nanog in the spinal cord tissue. Taken together, these data suggested that both Nanog may play important roles in spinal cord pathophysiology via interact with CDK6.

    Propofol preconditioning has been shown to provide neuroprotection against spinal ischemia/reperfusion injury. In this study, spinal cord ischemia/reperfusion injury was induced by blocking the abdominal aorta in rabbits for 40 minutes. Results showed that the co-application of propofol preconditioning and postconditioning regimen ameliorated pathological injury of the ischemic spinal cord and suppressed the elevation of malondialdehyde levels and increased superoxide dismutase activities in the spinal cord tissues. Co-application of propofol preconditioning and postconditioning resulted in potent protective effects against spinal cord ischemia/reperfusion injury and prolonged the spinal cord's tolerance to ischemia. This protection was associated with the anti-lipid peroxidation capacity of the spinal cord tissues.

We used rats to investigate spinal cord injury repair using bone marrow mesenchymal stem cell transplantation combined with propofol administration via the tail vein. Rat spinal cord injury was clearly alleviated; a large number of newborn non-myelinated and myelinated nerve fibers appeared in the spinal cord, the numbers of CM-Dil-labeled bone marrow mesenchymal stem cells and fluorogold-labeled nerve fibers were increased and hindlimb motor function of spinal cord-injured rats was markedly improved. These improvements were more prominent in rats subjected to bone marrow mesenchymal cell transplantation combined with propofol administration than in rats receiving monotherapy. These results indicate that propofol can enhance the therapeutic effects of bone marrow mesenchymal stem cell transplantation on spinal cord injury in rats.

    This study examined coping among caregivers of youth with spinal cord injuries (SCI). Using a cross-sectional survey study design, 164 caregivers completed a demographics questionnaire and the Brief COPE. Their children, youth with SCI ages 7-18, completed the Kidcope. T-tests were conducted to examine differences in caregiver coping by demographic and injury-related factors. Further, logistic regression models were evaluated to examine predictive relationships between caregiver coping and youth coping. Several demographic and injury-related factors were related to caregiver coping, including caregiver gender, race, and education, as well as youth gender, age at injury, and time since injury. In the logistic regressions, two caregiver coping strategies were related to youth coping: caregiver self-blame coping was related to youth self-criticism, and caregiver behavioral disengagement coping (giving up attempts to cope) was related to youth blaming others coping. The findings suggest that caregiver coping may play a role in the coping of their children, and should be considered when addressing coping among youth with SCI.

    2013-01-01

    Full Text Available Spinal cord injuries (SCIs often lead to impairment of the respiratory system and, consequently, restrictive respiratory changes. Paresis or paralysis of the respiratory muscles can lead to respiratory insufficiency, which is dependent on the level and completeness of the injury. Respiratory complications include hypoventilation, a reduction in surfactant production, mucus plugging, atelectasis, and pneumonia. Vital capacity (VC is an indicator of overall pulmonary function; patients with severely impaired VC may require assisted ventilation. It is best to proceed with intubation under controlled circumstances rather than waiting until the condition becomes an emergency. Mechanical ventilation can adversely affect the structure and function of the diaphragm. Early tracheostomy following short orotracheal intubation is probably beneficial in selected patients. Weaning should start as soon as possible, and the best modality is progressive ventilator-free breathing (PVFB. Appropriate candidates can sometimes be freed from mechanical ventilation by electrical stimulation. Respiratory muscle training regimens may improve patients’ inspiratory function following a SCI.

  11. SnoN facilitates axonal regeneration after spinal cord injury.

    Directory of Open Access Journals (Sweden)

    Jiun L Do

    Full Text Available Adult CNS neurons exhibit a reduced capacity for growth compared to developing neurons, due in part to downregulation of growth-associated genes as development is completed. We tested the hypothesis that SnoN, an embryonically regulated transcription factor that specifies growth of the axonal compartment, can enhance growth in injured adult neurons. In vitro, SnoN overexpression in dissociated adult DRG neuronal cultures significantly enhanced neurite outgrowth. Moreover, TGF-β1, a negative regulator of SnoN, inhibited neurite outgrowth, and SnoN over-expression overcame this inhibition. We then examined whether SnoN influenced axonal regeneration in vivo: indeed, expression of a mutant form of SnoN resistant to degradation significantly enhanced axonal regeneration following cervical spinal cord injury, despite peri-lesional upregulation of TGF-β1. Thus, a developmental mechanism that specifies extension of the axonal compartment also promotes axonal regeneration after adult CNS injury.

    2011-06-01

    The purpose of the present study was to explore the perspectives and experiences of Iranian patients regarding barriers and facilitators to their ability to cope with spinal cord injury (SCI). A qualitative design, based on the content analysis approach, was used to collect and analyze the experiences of 18 patients with spinal cord injury in two centers in Tehran, Iran. After using purposeful sampling for selection of the participants, semi-structured interviews were held for data collection. Lack of "knowledge", "financial resources", "employment opportunities", "suitable facilities and accessibility" as well as "societal acceptance and support" emerged as barriers; and having "self-confidence", "religious beliefs", "support networks" and "positive thinking" emerged as facilitators in coping with spinal cord injury. Participants believed that with these hindering factors in place, adapting to their new condition had been difficult, therefore they can only manage to adapt partially to their situation. Additional multidisciplinary endeavors are needed to help this group cope adequately and further research is required to influence policy making and legislation processes efficiently. © 2011 Blackwell Publishing Asia Pty Ltd.

    Full Text Available OBJECTIVE: Indicate and identify potential complications in our unit associated with the use of steroids in patients over 16 years of age with traumatic acute spinal cord injury managed with NASCIS II, III scheme compared with patients with the same characteristics who did not receive this management. METHODS: To conduct a research study with reports of cases and controls in patients over 16 years of age and with an established diagnosis of acute spinal cord injury, treated definitively in our unit, performing the comparison of evolutionary process between those treated with steroids and those who were not, based on the development of a data collection sheet with several variables.. The results were encoded, tabulated and analyzed. RESULTS: A total of 30 patients were analyzed from January to December 2012 and it was found that 16% of the patients managed with the steroid scheme required admission to the intensive care unit, 40% developed hospital-acquired pneumonia, 17% had urinary tract infection, 3% progressed to respiratory failure and 20% of this group had gastrointestinal bleeding. CONCLUSIONS: It was concluded that steroid management is not a risk-free therapy and the recommendation is to make a direct assessment of the potential benefit to its use in relation to the possible complications that can ensue before choosing this option in patients with traumatic spinal cord injury.

    The blood-spinal cord barrier (BSCB) is a specialized protective barrier that regulates the movement of molecules between blood vessels and the spinal cord parenchyma. Analogous to the blood-brain barrier (BBB), the BSCB plays a crucial role in maintaining the homeostasis and internal environmental stability of the central nervous system (CNS). After spinal cord injury (SCI), BSCB disruption leads to inflammatory cell invasion such as neutrophils and macrophages, contributing to permanent neurological disability. In this review, we focus on the major proteins mediating the BSCB disruption or BSCB repair after SCI. This review is composed of three parts. Section 1. SCI and the BSCB of the review describes critical events involved in the pathophysiology of SCI and their correlation with BSCB integrity/disruption. Section 2. Major proteins involved in BSCB disruption in SCI focuses on the actions of matrix metalloproteinases (MMPs), tumor necrosis factor alpha (TNF-α), heme oxygenase-1 (HO-1), angiopoietins (Angs), bradykinin, nitric oxide (NO), and endothelins (ETs) in BSCB disruption and repair. Section 3. Therapeutic approaches discusses the major therapeutic compounds utilized to date for the prevention of BSCB disruption in animal model of SCI through modulation of several proteins.

    1989-11-01

    Measurement of lower extremity muscle strength and the energy expenditure during walking was taken in 36 spinal cord injury patients to assess functional mobility. Patients were categorized according to the type of orthotic prescription (knee-ankle-foot orthosis [KAFO] or ankle-foot orthosis [AFO]) or upper extremity assistive device (cane, crutches, or walker) used during gait. The rates of O2 consumption per minute, O2 cost per meter, heart rate, respiratory quotient, velocity, cadence, and peak axial load exerted by the arms on upper extremity assistive devices were measured. The Ambulatory Motor Index (AMI), derived from the manual muscle grades of both lower limbs, was used as the indicator of the degree of paralysis. The AMI was strongly correlated with the percentage increase in the rate of O2 consumption above normal (p less than .0001), O2 cost per meter (p less than .0001), peak axial load (p less than .0001), velocity (p less than .0001), and cadence (p less than .0001). Differences in these parameters among patient groups categorized according to the type of orthotic prescription (no KAFO, one KAFO, two KAFOs) or upper extremity assistive device (no device, cane or one crutch, two crutches, or walker) were attributable to differences in the AMI. The AMI, therefore, could be used as a reliable clinical indicator of functional mobility after spinal cord injury.

  20. Muscular, skeletal, and neural adaptations following spinal cord injury.

    2002-02-01

    Spinal cord injury is associated with adaptations to the muscular, skeletal, and spinal systems. Experimental data are lacking regarding the extent to which rehabilitative methods may influence these adaptations. An understanding of the plasticity of the muscular, skeletal, and spinal systems after paralysis may be important as new rehabilitative technologies emerge in the 21st century. Moreover, individuals injured today may become poor candidates for future scientific advancements (cure) if their neuromusculoskeletal systems are irreversibly impaired. The primary purpose of this paper is to explore the physiological properties of skeletal muscle as a result of spinal cord injury; secondarily, to consider associated changes at the skeletal and spinal levels. Muscular adaptations include a transformation to faster myosin, increased contractile speeds, shift to the right on the torque-frequency curve, increased fatigue, and enhanced doublet potentiation. These muscular adaptations may be prevented in individuals with acute paralysis and partially reversed in individuals with chronic paralysis. Moreover, the muscular changes may be coordinated with motor unit and spinal circuitry adaptations. Concurrently, skeletal adaptations, as measured by bone mineral density, show extensive loss within the first six months after paralysis. The underlying science governing neuromusculoskeletal adaptations after paralysis will help guide professionals as new rehabilitation strategies evolve in the future.

  1. Understanding the NG2 glial scar after spinal cord injury

    Full Text Available NG2 cells, also known as oligodendrocyte progenitor cells, are located throughout the central nervous system and serve as a pool of progenitors to differentiate into oligodendrocytes. In response to spinal cord injury, NG2 cells increase their proliferation and differentiation into remyelinating oligodendrocytes. While astrocytes are typically associated with being the major cell type in the glial scar, many NG2 cells also accumulate within the glial scar but their function remains poorly understood. Similar to astrocytes, these cells hypertrophy, upregulate expression of chondroitin sulfate proteoglycans, inhibit axon regeneration, contribute to the glial-fibrotic scar border, and some even differentiate into astrocytes. Whether NG2 cells also have a role in other astrocyte functions, such as preventing the spread of infiltrating leukocytes and expression of inflammatory cytokines, is not yet known. Thus, NG2 cells are not only important for remyelination after spinal cord injury, but are also a major component of the glial scar with functions that overlap with astrocytes in this region. In this review, we describe the signaling pathways important for the proliferation and differentiation of NG2 cells, as well as the role of NG2 cells in scar formation and tissue repair.

  3. Inosine Improves Neurogenic Detrusor Overactivity following Spinal Cord Injury.

    Directory of Open Access Journals (Sweden)

    Yeun Goo Chung

    Full Text Available Neurogenic detrusor overactivity and the associated loss of bladder control are among the most challenging complications of spinal cord injury (SCI. Anticholinergic agents are the mainstay for medical treatment of detrusor overactivity. However, their use is limited by significant side effects such that a search for new treatments is warranted. Inosine is a naturally occurring purine nucleoside with neuroprotective, neurotrophic and antioxidant effects that is known to improve motor function in preclinical models of SCI. However, its effect on lower urinary tract function has not been determined. The objectives of this study were to determine the effect of systemic administration of inosine on voiding function following SCI and to delineate potential mechanisms of action. Sprague-Dawley rats underwent complete spinal cord transection, or cord compression by application of an aneurysm clip at T8 for 30 sec. Inosine (225 mg/kg or vehicle was administered daily via intraperitoneal injection either immediately after injury or after a delay of 8 wk. At the end of treatment, voiding behavior was assessed by cystometry. Levels of synaptophysin (SYP, neurofilament 200 (NF200 and TRPV1 in bladder tissues were measured by immunofluorescence imaging. Inosine administration decreased overactivity in both SCI models, with a significant decrease in the frequency of spontaneous non-voiding contractions during filling, compared to vehicle-treated SCI rats (p<0.05, including under conditions of delayed treatment. Immunofluorescence staining demonstrated increased levels of the pan-neuronal marker SYP and the Adelta fiber marker NF200, but decreased staining for the C-fiber marker, TRPV1 in bladder tissues from inosine-treated rats compared to those from vehicle-treated animals, including after delayed treatment. These findings demonstrate that inosine prevents the development of detrusor overactivity and attenuates existing overactivity following SCI, and may

    The spinal cord undergoes physical deformation during traumatic spinal cord injury (TSCI), which results in biological damage. This study demonstrates a novel approach, using magnetic resonance imaging and image registration techniques, to quantify the three-dimensional deformation of the cervical spinal cord in an in vivo rat model. Twenty-four male rats were subjected to one of two clinically relevant mechanisms of TSCI (i.e. contusion and dislocation) inside of a MR scanner using a novel apparatus, enabling imaging of the deformed spinal cords. The displacement fields demonstrated qualitative differences between injury mechanisms. Three-dimensional Lagrangian strain fields were calculated, and the results from the contusion injury mechanism were deemed most reliable. Strain field error was assessed using a Monte Carlo approach, which showed that simulated normal strain error experienced a bias, whereas shear strain error did not. In contusion injury, a large region of dorso-ventral compressive strain was observed under the impactor which extended into the ventral region of the spinal cord. High tensile lateral strains under the impactor and compressive lateral strains in the lateral white matter were also observed in contusion. The ability to directly observe and quantify in vivo spinal cord deformation informs our knowledge of the mechanics of TSCI.

    BACKGROUND: Valproic acid has been reported to decrease apoptosis, promote neuronal differentiation of brain-derived neural stem cells, and inhibit glial differentiation of brain-derived neural stem cells.OBJECTIVE: To investigate the effects of valproic acid on proliferation of endogenous neural sterm cells in a rat model of spinal cord injury.DESIGN, TIME AND SETTING: A randomized, controlled, neuropathological study was performed at Key Laboratory of Trauma, Buming, and Combined Injury, Research Institute of Surgery, Daping Hospital, the Third Military Medical University of Chinese PLA between November 2005 and February 2007.MATERIALS: A total of 45 adult, Wistar rats were randomly divided into sham surgery (n=5), injury(n=20), and valproic acid (n=20) groups. Valproic acid was provided by Sigma, USA.METHODS: Injury was induced to the T10 segment in the injury and valproic acid groups using the metal weight-dropping method. The spinal cord was exposed without contusion in the sham surgery group. Rats in the valproic acid group were intraperitoneally injected with 150 mg/kg valproic acid every 12 hours (twice in total).MAIN OUTCOME MEASURES: Nestin expression (5 mm from injured center) was detected using immunohistochemistry at 1, 3 days, 1, 4, and 8 weeks post-injury.RESULTS: Low expression of nestin was observed in the cytoplasm, but rarely in the white matter of the spinal cord in the sham surgery group. In the injury group, nestin expression was observed in the ependyma and pia mater one day after injury, and expression reached a peak at 1 week (P<0.05).Expression was primarily observed in the ependymal cells, which expanded towards the white and gray matter of the spinal cord. Nestin expression rapidly decreased by 4 weeks post-injury, and had almost completely disappeared by 8 weeks. At 24 hours after spinal cord injury, there was nosignificant difference in nestin expression between the valproic acid and injury groups. At 1 week,there was a significant

    We recently showed that, after traumatic spinal cord injury (TSCI), laminectomy does not improve intraspinal pressure (ISP), spinal cord perfusion pressure (SCPP), or the vascular pressure reactivity index (sPRx) at the injury site sufficiently because of dural compression. This is an open label, prospective trial comparing combined bony and dural decompression versus laminectomy. Twenty-one patients with acute severe TSCI had re-alignment of the fracture and surgical fixation; 11 had laminectomy alone (laminectomy group) and 10 had laminectomy and duroplasty (laminectomy+duroplasty group). Primary outcomes were magnetic resonance imaging evidence of spinal cord decompression (increase in intradural space, cerebrospinal fluid around the injured cord) and spinal cord physiology (ISP, SCPP, sPRx). The laminectomy and laminectomy+duroplasty groups were well matched. Compared with the laminectomy group, the laminectomy+duroplasty group had greater increase in intradural space at the injury site and more effective decompression of the injured cord. In the laminectomy+duroplasty group, ISP was lower, SCPP higher, and sPRx lower, (i.e., improved vascular pressure reactivity), compared with the laminectomy group. Laminectomy+duroplasty caused cerebrospinal fluid leak that settled with lumbar drain in one patient and pseudomeningocele that resolved completely in five patients. We conclude that, after TSCI, laminectomy+duroplasty improves spinal cord radiological and physiological parameters more effectively than laminectomy alone.

    2011-12-01

    We present a retrospective case series of 15 children (aged 8-16 years) with blunt traumatic spinal cord injury who were treated with methylprednisolone as per the National Acute Spinal Cord Injury Study protocol. Of all patients, 12 (80%) were male. Causes were sports injuries (n = 9), motor vehicle crashes (n = 2), and falls (n = 4). Most injuries were nonskeletal (n = 14), and all patients had incomplete injury of the spinal cord. The most common location of tenderness was cervical (n = 7). Of the 15 patients, methylprednisolone was initiated within 3 hours in 13 patients and between 3 and 8 hours in 2 patients. All patients received the medication for 23 hours as per the National Acute Spinal Cord Injury Study protocol. Of the 15 patients, 13 recovered completely by 24 hours and were discharged with a diagnosis of spinal cord concussion. One patient had compression fracture of T5 and T3-T5 spinal contusion but no long-term neurological deficit. One patient was discharged with diagnosis of C1-C3 spinal cord contusion (by magnetic resonance imaging) and had partial recovery at 2 years after injury. All patients with a diagnosis of cord concussion had normal plain films of the spine and computed tomographic and magnetic resonance imaging findings. None of the patients had any associated major traumatic injuries to other organ systems. The high-dose steroid therapy did not result in any serious bacterial infections.

    Central neuropathic pain is a debilitating and frequent complication to spinal cord injury (SCI). Excitatory input from hyperexcitable cells around the injured grey matter zone is suggested to play a role for central neuropathic pain felt below the level of a spinal cord injury. Direct evidence...... of a spinal cord injury which already is hyperexcitable, would cause enhanced responses in patients with central pain at the level of injury compared to patients without neuropathic pain and healthy controls. Touch, punctuate stimuli, cold stimuli and topical capsaicin was applied above, at, and below injury...... level in 10 SCI patients with central pain below a thoracic injury, in 10 SCI patients with a thoracic injury but without neuropathic pain, and in corresponding areas in 10 healthy control subjects. The study found increased responses to touch at injury level compared to controls (p = 0...

    The correlation between the anatomic site of spinal cord injury and real-time conditions of bladder and urethral function was assessed in order to provide a reasonable basis for the clinical treat-ment of neurogenic bladder. A total of 134 patients with spinal cord injuries (105 males, 29 females;averaged 34.1 years old) were involved in this retrospective analysis, including urodynamic evaluation,clinical examination and imaging for anatomical position, and Bors-Comarr classification. The associa-tions between the levels of injury and urodynamic findings were analyzed. The results showed that mean follow-up duration was 16.7 months (range 8-27 months). Complete spinal cord injuries occurred in 21 cases, and incomplete spinal cord injuries in 113 cases. Of the 43 patients with upper motor neu-ron (UMN) injuries, hyperreflexia and (or) detmsor sphincter dyssynergia were demonstrated in 30 (69.8%), 31 (72.1%) suffered low bladder compliance (less than 12.5 mL/cmH2O), 28 (65.1%) had high detrusor leak point pressures (greater than 40 cmH2O), and 34 (79.1%) had residual urine. Of the 91 pa-tients with lower motor neuron (LMN) injuries, areflexia occurred in 78 (85.7%), high compliance in 75 (82.4%), low leak point pressures in 80 (87.9%), and residual urine in 87 (95.6%), respectively. The as-sociations between the anatomical site of spinal cord injury and urodynamic findings were ill defined. In patients with spinal cord injury, this study revealed a significant association between the level of injury and the type of voiding dysfunction. The anatomical site of spinal cord injury can not be predicted in real-time condition of bladder and urethral function. Management of neurogenic bladder in patients with spinal cord injury must be based on urodynamic findings rather than inferences from the neurologic evaluation.

    The Initial Systolic Time Interval (ISTI), obtained from the electrocardiogram and impedance cardiogram, is considered to be a measure for the time delay between the electrical and mechanical activity of the heart. This time delay is influenced by the sympathetic nerve system. Therefore, an observational study was performed in a group of patients (SCI) with spinal cord injuries. The relationship between the ISTI and the total heart cycle (RR-interval) was established by varying the RR-interval using an exercise stimulus to increase the heart rate. The slope of this relationship was observed to be significantly higher in the SCI-group as compared with a control group, although there was no difference in ISTI in the range of common heart rates during the test between the groups. This slope and the ISTI was observed to be significantly different in an acute patient having a recent spinal cord injury at a high level. Because of the variety in injury levels and incompleteness of the injuries further, more specific research is necessary to draw decisive conclusions with respect to the contribution of autonomic nervous control on the ISTI in SCI, although the present observations are notable.

    Objective To identify dermatological conditions following spinal cord injury (SCI) and analyze these conditions in relation to various characteristics of SCI. Design Retrospective chart review. Setting National Health Insurance Corporation Ilsan Hospital of Korea, Rehabilitation Center, Spinal Cord Unit. Participants Patients treated for SCI who were referred to dermatology for dermatological problems, 2000–2012. Results Of the 1408 SCI patients treated at the spinal cord unit, 253 patients with SCI were identified to have been referred to dermatology for skin problems and a total of 335 dermatological conditions were diagnosed. The most common dermatological finding was infectious (n = 123, 36.7%) followed by eczematous lesions (n = 109, 32.5%). Among the infectious lesions, fungal infection (n = 76, 61.8%) was the most common, followed by bacterial (n = 27, 21.9%) lesions. Seborrheic dermatitis (n = 59, 64.1%) was the most frequent eczematous lesion. Ingrown toenail occurred more frequently in tetraplegics whereas vascular skin lesions occurred more commonly in patients with paraplegia (P < 0.05). Xerotic dermatitis showed a higher occurrence within 12 months of injury rather than thereafter (P < 0.05). Of these, 72.4% of the infectious and 94.7% of the fungal skin lesions manifested below the neurological level of injury (NLI; P < 0.001) and 61.5% of the eczematous lesions and 94.9% of seborrheic dermatitis cases occurred above the NLI (P < 0.001). There was no significant difference in dermatological diagnoses between patients with neurologically complete and incomplete SCI. Conclusion The most common dermatological condition in patients with SCI among those referred to dermatology was fungal infection, followed by seborrheic dermatitis. Although dermatological problems after SCI are not critical in SCI outcome, they negatively affect the quality of life. Patients and caregivers should be educated about appropriate skin care and routine

    Intrathecal injection of dynorphin into rats via subarachnoid catheter induces damage to spinal cord tissue and motor function. Injection of the kappa opioid receptor antagonist nor-binaltorphine, or the excitatory amino acid N-methyl-D-aspartate receptor antagonist MK-801 into rats alleviated the pathological changes of dynorphin-caused spinal cord tissue injury and reduced the acid phosphatase activity in the spinal cord. The experimental findings indicate that there are opioid and non-opioid pathways for dynorphin-induced spinal cord injury, and that the non-opioid receptor pathway may be mediated by the excitatory amino acid N-methyl-D-aspartate receptor.

    BACKGROUND: Some researches showed that motoneurons in spinal cord anterior horn wound die following brachial plexus injury, but the concrete mechanism of motoneurons death remains unclear.OBJECTIVE: To observe the expression of nitric oxide synthase (NOS) and survival of C7 motoneurons in spinal cord of rats after selective brachial plexus injury.DESIGN: A randomized controlled animal experiment.SETTING: Department of Anatomy, Sun Yet-sen Medical College, Sun Yet-sen University.MATERIALS: Totally 35 adult healthy male Sprague-Dawley rats with the body mass of 200-300 g were provided by Experimental Animal Center, Sun Yet-sen Medical College, Sun Yat-sen University. The rats were divided into control group (n =5) and experimental group (n=30) by random number table method, and the experimental group was divided into three injury subgroups: anterior root avulsion group, dorsal root transection group and spinal cord hemisection group, 10 rats in each group. There were horse anti-neuronal NOS (Nnos) polycolonal antibody (Sigma company) and nicotina mideadeninedinucleotide phosphate (NADPH-d) (SigmaCompany).METHODS: The experiment was performed at Department of Anatomy, Sun Yet-sen Medical College, Sun Yet-sen University between September 2004 and April 2005. ①After anesthetizing the rats, the spinous process of second thoracic vertebra as a marker, the vertebra was exposed from C5 to T1 and the lamina of vertebra was unclenched, and spinal dura mater was carved to expose the spinal nerve dorsal roots of C5-T1.The right ventral root of C7 was avulsed, and the residual root was removed in anterior root avulsion group. The right ventral root of C7 was avulsed and the right dorsal roots of brachial plexus (C5-T1) were cut off in dorsal root transection group. In spinal cord hemisection group, the hemisection between the C5 and C6 spinal segment on right side and avulsion of right ventral root of C7 were made. In the control group, the vertebra from C5 to T1 was

    2013-02-01

    An estimated 12,000 new cases of spinal cord injury (SCI) occur every year in the United States. A small oxidative molecule responsible for secondary injury, acrolein, is an important target in SCI. Acrolein attacks essential proteins and lipids, creating a feed-forward loop of oxidative stress in both the primary injury area and the surrounding areas. A small molecule used and FDA-approved for hypertension, hydralazine, has been found to "scavenge" acrolein after injury, but its delivery and short half-life, as well as its hypertension effects, hinder its application for SCI. Nanomedical systems broaden the range of therapeutic availability and efficacy over conventional medicine. They allow for targeted delivery of therapeutic molecules to tissues of interest, reducing side effects of untargeted therapies in unwanted areas. Nanoparticles made from silica form porous networks that can carry therapeutic molecules throughout the body. To attenuate the acrolein cascade and improve therapeutic availability, we have used a one-step, modified Stober method to synthesize two types of silica nanoparticles. Both particles are "stealth-coated" with poly(ethylene) glycol (PEG) (to minimize interactions with the immune system and to increase circulation time), which is also a therapeutic agent for SCI by facilitating membrane repair. One nanoparticle type contains an amine-terminal PEG (SiNP-mPEG-Am) and the other possesses a terminal hydrazide group (SiNP-mPEG-Hz). The former allows for exploration of hydralazine delivery, loading, and controlled release. The latter group has the ability to react with acrolein, allowing the nanoparticle to scavenge directly. The nanoparticles have been characterized and are being explored using neuronal PC-12 cells in vitro, demonstrating the potential of novel silica nanoparticles for use in attenuating secondary injury after SCI.

    Background/objective To describe the nature and distribution of activities during physical therapy (PT) delivered in inpatient spinal cord injury (SCI) rehabilitation and discuss predictors (patient and injury characteristics) of the amount of time spent in PT for specific treatment activities. Methods Six hundred patients from six inpatient SCI centers were enrolled in the SCIRehab study. Physical therapists documented details, including time spent, of treatment provided during 37 306 PT sessions that occurred during inpatient SCI rehabilitation. Ordinary least squares regression models associated patient and injury characteristics with time spent in specific PT activities. Results SCIRehab patients received a mean total of 55.3 hours of PT over the course of their rehabilitation stay. Significant differences among four neurologic groups were seen in the amount of time spent on most activities, including the most common PT activities of strengthening exercises, stretching, transfer training, wheelchair mobility training, and gait training. Most PT work (77%) was provided in individual therapy sessions; the remaining 23% was done in group settings. Patient and injury characteristics explained only some of the variations seen in time spent on wheelchair mobility, transfer and bed mobility training, and range of motion/stretching. Conclusion Analysis yielded both expected and unexpected trends in SCI rehabilitation. Significant variation was seen in time spent on PT activities within and among injury groups. Providing therapeutic strengthening treatments consumed the greatest proportion of PT time. About one-quarter of all PT services were provided in group settings. Details about services provided, including time spent, will serve as a starting point in detailing the optimal treatment delivery for maximal outcomes. PMID:21675354

    Major advances in neonatal care have led to significant improvements in survival rates for preterm infants, but this occurs at a cost, with a strong causal link between preterm birth and neurological deficits, including cerebral palsy (CP). Indeed, in high-income countries, up to 50% of children with CP were born preterm. The pathways that link preterm birth and brain injury are complex and multifactorial, but it is clear that preterm birth is strongly associated with damage to the white matter of the developing brain. Nearly 90% of preterm infants who later develop spastic CP have evidence of periventricular white matter injury. There are currently no treatments targeted at protecting the immature preterm brain. Umbilical cord blood (UCB) contains a diverse mix of stem and progenitor cells, and is a particularly promising source of cells for clinical applications, due to ethical and practical advantages over other potential therapeutic cell types. Recent studies have documented the potential benefits of UCB cells in reducing brain injury, particularly in rodent models of term neonatal hypoxia-ischemia. These studies indicate that UCB cells act via anti-inflammatory and immuno-modulatory effects, and release neurotrophic growth factors to support the damaged and surrounding brain tissue. The etiology of brain injury in preterm-born infants is less well understood than in term infants, but likely results from episodes of hypoperfusion, hypoxia-ischemia, and/or inflammation over a developmental period of white matter vulnerability. This review will explore current knowledge about the neuroprotective actions of UCB cells and their potential to ameliorate preterm brain injury through neonatal cell administration. We will also discuss the characteristics of UCB-derived from preterm and term infants for use in clinical applications.

    Background Occupational therapy (OT) is a critical component of the rehabilitation process after spinal cord injury (SCI), the constitution of which has not been studied or documented in full detail previously. Objective To describe the type and distribution of SCI rehabilitation OT activities, including the amount of time spent on evaluation and treatment, and to discuss predictors (patient and injury characteristics) of the amount of time dedicated to OT treatment activities. Methods Six inpatient rehabilitation centers enrolled 600 patients with traumatic SCI in the first year of the SCIRehab. Occupational therapists documented 32 512 therapy sessions including time spent and specifics of each therapeutic activity. Analysis of variance and contingency tables/chi-square tests were used to test differences across neurologic injury groups for continuous and categorical variables. Results SCIRehab patients received a mean total of 52 hours of OT over the course of their rehabilitation stay. Statistically significant differences among four neurologic injury groups were seen in time spent on each OT activity. The activities that consumed the most OT time (individual and group sessions combined) were strengthening/endurance exercises, activities of daily living (ADLs), range of motion (ROM)/stretching, education, and a grouping of ‘therapeutic activities’ that included tenodesis training, fine motor activities, manual therapy, vestibular training, edema management, breathing exercise, cognitive retraining, visual/perceptual training desensitization, and don/doff adaptive equipment. Seventy-seven percent of OT work occurred in individual treatment sessions, with the most frequent OT activity involving ADLs. The variation in time (mean minutes per week) spent on OT ROM/stretching, ADLs, transfer training, assessment, and therapeutic activities can be explained in part by patient and injury characteristics, such as admission Functional Independence Measure (FIM

    The expression of adrenomedullin (ADM) in injured tissue of rat spinal cord was observed and the effect of recombinant human erythropoietin was analyzed. A total of 45 Sprague-Dawley rats were selected and divided into 3 equal groups including, a sham-operation group in which rats received an excision of vertebral plate; a spinal cord injury model group and a recombinant human erythropoietin group in which rats with spinal cord injury received a caudal vein injection of 300 units recombinant human erythropoietin after injury. Hematoxylin and eosin staining was performed to observe the spinal cord injury conditions. Immunohistochemical staining was performed to observe the expression of ADM. Pathologic changes in the group of recombinant human erythropoietin at various times were significantly less severe than those in the group of spinal cord injury model. The expression of ADM was increased particularly in the group of recombinant human erythropoietin (P<0.01). The improved Tarlov scores of the group of spinal cord injury model and the group of recombinant human erythropoietin were lower than those of the sham-operation group at 3, 6 and 9 days (P<0.01). Thus, the recombinant human erythropoietin is capable of alleviating the secondary injury of spinal cord. One of the mechanisms may be achieved by promoting the increase of ADM expression.

    To report the results of use of a human oscillating field stimulator (OFS) in a phase 1 trial of 14 human patients with complete motor and sensory spinal cord injury. Entry criteria were complete spinal cord injury between C5 and T10 in patients 18-65 years old with no transection on magnetic resonance imaging. All patients received the National Acute Spinal Cord Injury Study III methylprednisolone protocol. Cord compression or instability was treated before entry. All patient injuries remained complete (based on American Spinal Cord Injury scoring) with no somatosensory evoked potentials (SSEPs) below the injury after surgery or for 48 hours. All patients were implanted with the OFS within 18 days. Patients were checked every 2 weeks after implantation. The OFS was explanted at 15 weeks. Independent neurologic examinations (American Spinal Cord Injury score, visual analog scale for pain, and SSEPs) were done at 6 weeks, 6 months, and 1 year. Statistical analyses were done by Wilcoxon rank sum test and analysis of variance (ANOVA). There were no complications at insertion, and one wound infection occurred after explant for a 3.5% infection rate. One patient was lost to follow-up after 6 months. All 14 patients had a mean visual analog scale score of 8 at implant and 2 at 6 months, and 13 remained a mean score of 2 at 1 year. Mean improvement in light touch score at 1 year was 25.9 points (ANOVA, P injuries, six had improvement in arm SSEPs, and one recovered a tibial SSEP. Of six patients with thoracic injuries, one recovered an abnormal lower SSEP. Treatment of human spinal cord injury with an OFS is safe, reliable, and easy. Compared with National Acute Spinal Cord Injury Study III compliant paralyzed patients, our results suggest efficacy. Copyright © 2014 Elsevier Inc. All rights reserved.

    Background Clinical trials in spinal cord injury (SCI) primarily rely on simplified outcome metrics (ie, speed, distance) to obtain a global surrogate for the complex alterations of gait control. However, these assessments lack sufficient sensitivity to identify specific patterns of underlying impairment and to target more specific treatment interventions. Objective To disentangle the differential control of gait patterns following SCI beyond measures of time and distance. Methods The gait of 22 individuals with motor-incomplete SCI and 21 healthy controls was assessed using a high-resolution 3-dimensional motion tracking system and complemented by clinical and electrophysiological evaluations applying unbiased multivariate analysis. Results Motor-incomplete SCI patients showed varying degrees of spinal cord integrity (spinal conductivity) with severe limitations in walking speed and altered gait patterns. Principal component (PC) analysis applied on all the collected data uncovered robust coherence between parameters related to walking speed, distortion of intralimb coordination, and spinal cord integrity, explaining 45% of outcome variance (PC 1). Distinct from the first PC, the modulation of gait-cycle variables (step length, gait-cycle phases, cadence; PC 2) remained normal with respect to regained walking speed, whereas hip and knee ranges of motion were distinctly altered with respect to walking speed (PC 3). Conclusions In motor-incomplete SCI, distinct clusters of discretely controlled gait parameters can be discerned that refine the evaluation of gait impairment beyond outcomes of walking speed and distance. These findings are specifically different from that in other neurological disorders (stroke, Parkinson) and are more discrete at targeting and disentangling the complex effects of interventions to improve walking outcome following motor-incomplete SCI.

    Spinal cord injury (SCI) is a common cause of mortality and neurological morbidity. Although progress had been made in the last decades in medical, surgical, and rehabilitation treatments for SCI, the outcomes of these approaches are not yet ideal. The use of cell transplantation as a therapeutic strategy for the treatment of SCI is very promising. Cell therapies for the treatment of SCI are limited by several translational road blocks, including ethical concerns in relation to cell sources. The use of iPSCs is particularly attractive, given that they provide an autologous cell source and avoid the ethical and moral considerations of other stem cell sources. In addition, different cell types, that are applicable to SCI, can be created from iPSCs. Common cell sources used for reprogramming are skin fibroblasts, keratinocytes, melanocytes, CD34+ cells, cord blood cells and adipose stem cells. Different cell types have different genetic and epigenetic considerations that affect their reprogramming efficiencies. Furthermore, in SCI the iPSCs can be differentiated to neural precursor cells, neural crest cells, neurons, oligodendrocytes, astrocytes, and even mesenchymal stromal cells. These can produce functional recovery by replacing lost cells and/or modulating the lesion microenvironment.

    2011-01-01

    Full Text Available Erythropoietin (EPO, originally identified for its critical function in regulating production and survival of erythrocytes, is a member of the type 1 cytokine superfamily. Recent studies have shown that EPO has cytoprotective effects in a wide variety of cells and tissues. Here is presented the analysis of EPO effects on spinal cord injury (SCI, considering both animal experiments concerning to mechanisms of neurodegeneration in SCI and EPO as a neuroprotective agent, and some evidences coming from ongoing clinical trials. The evidences underling that EPO could be a promising therapeutic agent in a variety of neurological insults, including trauma, are mounting. In particular, it is highlighted that administration of EPO or other recently generated EPO analogues such as asialo-EPO and carbamylated-EPO demonstrate interesting preclinical and clinical characteristics, rendering the evaluation of these tissue-protective agents imperative in human clinical trials. Moreover the demonstration of rhEPO and its analogues’ broad neuroprotective effects in animal models of cord lesion and in human trial like stroke, should encourage scientists and clinicians to design clinical trials assessing the efficacy of these pharmacological compounds on SCI.

    A 17-year-old patient was aggressively attacked and stabbed in the dorsal region of his back by a knife. He was admitted to the emergency room of the Hammoud Hospital University Medical Center, Saida, Lebanon lying in the prone position. The neurological examination revealed that the stabbing object was fixed at the dorsal spine level at the T-7 level, where it was inserted inside the vertebral body. Luckily, the blade of the knife was parallel to the nervous tracts of the spinal cord; thus, he showed no neurological deficits. This case provides an overview of how neurosurgical principles can be applied to trauma patients with spine injuries due to close combat weapons.

    This article reviews the pathology of human spinal cord injury (SCI), focusing on potential differences between humans and experimental animals, as well as on aspects that may have mechanistic or therapeutic relevance. Importance is placed on astrocyte and microglial reactions. These cells carry out a myriad of functions and we review the evidence that supports their beneficial or detrimental effects. Likewise, vascular responses and the role of inflammation and demyelination in the mechanism of SCI are reviewed. Lastly, schwannosis is discussed, highlighting its high frequency and potential role when designing therapeutic interventions. We anticipate that a better understanding of the pathological responses in the human will be useful to investigators in their studies on the pathogenesis and therapy of SCI.

    A sectional study that had as its objectives to assess caregiver burden of for caregivers of individuals with Traumatic Spinal Cord Injury (TSCI) and its association with sociodemographic variables (age and sex), health status (self-reported illnesses) and caregiver characteristics (care time in years and daily hours of care). Data were collected by consultation of patient files and individual interviews at home using the instrument, Caregiver Burden Scale (CBScale). The results showed that most burden occurred in the domains: environment, disappointment and general strain. Presenting health problem (for all domains of the CBScale) and spending more hours per day in care (in the domain disappointment) represented the variables associated with burden. Studies of a more confirmatory nature than exploratory between the variables studied can be used to measure the burden obtained in this population of caregivers of individuals with TSCI.

    This article describes noninvasive acute and long-term management of the respiratory muscle paralysis of high spinal cord injury (SCI). This includes full-setting, continuous ventilatory support by noninvasive intermittent positive pressure ventilation (NIV) to support inspiratory muscles and mechanically assisted coughing (MAC) to support inspiratory and expiratory muscles. The NIV and MAC can also be used to extubate or decannulate 'unweanable' patients with SCI, to prevent intercurrent respiratory tract infections from developing into pneumonia and acute respiratory failure (ARF), and to eliminate tracheostomy and resort to costly electrophrenic/diaphragm pacing (EPP/DP) for most ventilator users, while permitting glossopharyngeal breathing (GPB) for security in the event of ventilator failure.

    哺乳动物雷帕霉素靶蛋白(Mammalian target of rapamycin,mTOR)信号通路在细胞代谢,增殖与存活,血管生成,延缓细胞衰老中发挥着关键作用.另外,mTOR信号通路在各种中枢神经系统疾病和中枢神经系统创伤及修复中起着非常关键的作用.近年来,mTOR信号通路相关抑制药物相继问世,并在免疫抑制和抗肿瘤方面取得了一定的临床疗效.mTOR信号通路的细胞分子机制已成为研究热点.本文就调节mTOR信号通路在脊髓损伤中产生神经保护、神经再生效应的研究进展进行综述.%The mammalian target or rapamycin (mTOR) signaling pathway plays an important role in multiple cellular functions, such as cell metabolism, proliferation and survival. Many previous studies have shown that mTOR regulates both neuron-protective and neuron-regenerative functions in trauma and various diseases in the central nervous system. In recent years, the inhibitors of mTOR signaling pathway have been developed in succession, which have exhibited definite clinical effects on both immunosuppressive and tumor suppressive. As a result, further research on this pathway and its mechanisms in various diseases have become one of the hot research areas. This paper reviews the research progress of mTOR in spinal cord injury.

    OBJECTIVE: To investigate the status of olfactory ensheathing cells (OECs) transplantation in facilitating the regeneration of spinal cord injury.DATA SOURCES: Articles about OECs transplantation in treating spinal cord injury were searched in Pubmed database published in English from January 1981 to December 2005 by using the keywords of "olfactory ensheathing cells, transplantation, spinal cord injury".STUDY SELECTION: The data were checked primarily, literatures related to OECs transplantation and the regeneration of spinal cord injury were selected, whereas the repetitive studies and reviews were excluded.DATA EXTRACTION: Totally 43 articles about OECs transplantation and the regeneration and repair of spinal cord injury were collected, and the repetitive ones were excluded.DATA SYNTHESIS: There were 35 articles accorded with the criteria. OECs are the olfactory ensheathing glias isolated from olfactory bulb and olfactory nerve tissue. OECs have the characters of both Schwann cells in central nervous system and peripheral astrocytes. The transplanted OECs can migrate in the damaged spinal cord of host, can induce and support the regeneration, growth and extension of damaged neuritis.Besides, transgenic technique can enable it to carry some exogenous genes that promote neuronal regeneration, and express some molecules that can facilitate neural regeneration, so as to ameliorate the internal environment of nerve injury, induce the regeneration of damaged spinal cord neurons, which can stimulate the regeneration potential of the damaged spinal cord to reach the purpose of spinal cord regeneration and functional recovery.CONCLUSION: OECs are the glial cells with the energy for growth at mature phase, they can myelinize axons, secrete various biological nutrition factors, and then protect and support neurons, also facilitate neural regeneration. OECs have been successfully isolated from nasal olfactory mucosa and olfactory nerve.Therefore, autologous transplantation

    Full Text Available A pool of endogenous neural progenitor cells found in the ependymal layer and the sub-ependymal area of the spinal cord are reported to upregulate nestin in response to traumatic spinal cord injury. These cells could potentially be manipulated within a critical time period offering one innovative approach to the repair of spinal cord injury. However, little is known about the temporal response of endogenous neural progenitor cells following spinal cord injury. This study used a mild contusion injury in rat spinal cord and immunohistochemistry to determine the temporal response of ependymal neural progenitor cells following injury and their correlation to astrocyte activation at the lesion site. The results from the study demonstrated that Nestin staining intensity at the central canal peaked at 24 hours post-injury and then gradually declined over time. Reactive astrocytes double labelled by Nestin and GFAP were found at the lesion edge and commenced to form the glial scar from 1 week after injury. We conclude that the critical time period for manipulating endogenous neural progenitor cells following a spinal cord injury in rats is between 24 hrs when nestin expression in ependymal cells is increased and 1 week when astrocytes are activated in large numbers.

    Changes in mitochondrial morphology and function play an important role in secondary damage after acute spinal cord injury. We re-corded the time representation of mitochondrial morphology and function in rats with acute spinal cord injury. Results showed that mitochondria had an irregular shape, and increased in size. Mitochondrial cristae were disordered and mitochondrial membrane rupture was visible at 2–24 hours after injury. Fusion protein mitofusin 1 expression gradually increased, peaked at 8 hours after injury, and then decreased to its lowest level at 24 hours. Expression of dynamin-related protein 1, amitochondrial ifssion protein, showed the opposite kinetics. At 2–24 hours after acute spinal cord injury, malondialdehyde content, cytochrome c levels and caspase-3 expression were in-creased, but glutathione content, adenosine triphosphate content, Na+-K+-ATPase activity and mitochondrial membrane potential were gradually reduced. Furthermore, mitochondrial morphology altered during the acute stage of spinal cord injury. Fusion was important within the ifrst 8 hours, but ifssion played a key role at 24 hours. Oxidative stress was inhibited, biological productivity was diminished, and mitochondrial membrane potential and permeability were reduced in the acute stage of injury. In summary, mitochondrial apoptosis is activated when the time of spinal cord injury is prolonged.

To determine the true impact of SCI, this systematic review aims to summarize literature reporting on either the incidence or prevalence of SCI. Methods: A systematic search was conducted using PubMed, MEDLINE, MEDLINE in process, EMBASE, Cochrane Controlled Trial Register, and Cochrane Database of Systematic Reviews to identify relevant literature published through June 2013. We sought studies that provided regional, provincial/state, or national data on the incidence of SCI or reported estimates of disease prevalence. The level of evidence of each study was rated using a scale that evaluated study design, methodology, sampling bias, and precision of estimates. Results: The initial search yielded 5,874 articles, 48 of which met the inclusion criteria. Forty-four studies estimated the incidence of SCI and nine reported the prevalence, with five discussing both. Of the incidence studies, 14 provided figures at a regional, ten at a state or provincial level and 21 at a national level. The prevalence of SCI was highest in the United States of America (906 per million and lowest in the Rhone-Alpes region, France (250 per million and Helsinki, Finland (280 per million. With respect to states and provinces in North America, the crude annual incidence of SCI was highest in Alaska (83 per million and Mississippi (77 per million and lowest in Alabama (29.4 per million, despite a large percentage of violence injuries (21.2%. Annual incidences were above 50 per million in the Hualien County in Taiwan (56.1 per million, the central Portugal

    Study design Retrospective chart review. Objective To define the temporal course of weight gain in persons with new spinal cord injury (SCI), and to identify predictors of weight gain in this population. Setting A United States Department of Veterans Affairs (VA) SCI Unit. Methods A retrospective chart review in a VA SCI Unit was conducted. Participants (n = 85) included all persons with new SCI completing initial rehabilitation at the center between 1998 and 2006. Outcome measures were mean change in body mass index (BMI) between rehabilitation admission and final follow-up, time of greatest BMI change, and distribution of participants by BMI classification. These measures were also examined relative to SCI level, American Spinal Injury Association Impairment Scale (AIS) grade, primary mode of mobility, and age at rehabilitation admission. Results Mean BMI increased by 2.3 kg/m2 between rehabilitation admission (mean 45 days post-injury) and final follow-up (mean 5 years post-injury). The distribution of participants shifted from lower BMI classifications at rehabilitation admission to higher BMI classifications at final follow-up. For participants transitioning from normal to overweight or obese, the greatest increase occurred during the first year after acute rehabilitation. Neurological level, impairment category, primary mode of mobility, and age at rehabilitation admission did not significantly predict BMI change. BMI at rehabilitation admission correlated significantly with BMI at final follow-up (P < 0.0005). Conclusions These findings confirm a significant increase in BMI after new SCI and suggest that persons with new SCI are at greatest weight gain risk during the first year following acute rehabilitation.

    Full Text Available Methylprednisolone sodium succinate (MPSS for treatment of acute spinal cord injury (SCI has been associated with both benefits and adverse events. MPSS administration was the standard of care for acute SCI until recently when its use has become controversial. Patients with SCI have had little input in the debate, thus we sought to learn their opinions regarding administration of MPSS. A summary of the published literature to date on MPSS use for acute SCI was created and adjudicated by 28 SCI experts. This summary was then emailed to 384 chronic SCI patients along with a survey that interrogated the patients' neurological deficits, communication with physicians and their views on MPSS administration. 77 out of 384 patients completed the survey. 28 respondents indicated being able to speak early after injury and of these 24 reported arriving at the hospital within 8 hours of injury. One recalled a physician speaking to them about MPSS and one patient reported choosing whether or not to receive MPSS. 59.4% felt that the small neurological benefits associated with MPSS were 'very important' to them (p<0.0001. Patients had 'little concern' for potential side-effects of MPSS (p = 0.001. Only 1.4% felt that MPSS should not be given to SCI patients regardless of degree of injury (p<0.0001. This is the first study to report SCI patients' preferences regarding MPSS treatment for acute SCI. Patients favor the administration of MPSS for acute SCI, however few had input into whether or not it was administered. Conscious patients should be given greater opportunity to decide their treatment. These results also provide some guidance regarding MPSS administration in patients unable to communicate.

    Spinal cord ischemia/reperfusion injury is a stress injury to the spinal cord. Our previous studies using differential proteomics identified 21 differential y expressed proteins (n > 2) in rabbits with spinal cord ischemia/reperfusion injury. Of these proteins, stress-related proteins included protein disulfide isomerase A3, stress-induced-phosphoprotein 1 and heat shock cognate protein 70. In this study, we established New Zealand rabbit models of spinal cord ischemia/reperfusion injury by abdominal aorta occlusion. Results demonstrated that hind limb function initial y improved after spinal cord ischemia/reperfusion injury, but then deteriorated. The pathological morphology of the spinal cord became aggravated, but lessened 24 hours after reperfusion. However, the numbers of motor neurons and interneurons in the spinal cord gradual y decreased. The expression of protein disulfide isomerase A3, stress-induced-phosphoprotein 1 and heat shock cognate protein 70 was induced by ischemia/reperfusion injury. The expression of these proteins increased within 12 hours after reperfusion, and then decreased, reached a minimum at 24 hours, but subsequently increased again to similar levels seen at 6–12 hours, showing a characterization of induction-inhibition-induc-tion. These three proteins were expressed only in cytoplasm but not in the nuclei. Moreover, the expression was higher in interneurons than in motor neurons, and the survival rate of interneurons was greater than that of motor neurons. It is assumed that the expression of stress-related proteins exhibited a protective effect on neurons.

    Cervical contusive trauma accounts for the majority, of human spinal cord injury (SCI), yet experimental use of cervical contusion injury models has been limited. Considering that (1) the different ways of injuring the spinal cord (compression, contusion, and transection) induce very different processes of tissue damage and (2) the architecture of the spinal cord is not uniform, it is important to use a model that is more clinically applicable to human SCI. Therefore, in the current study we have developed a rat model of contusive, cervical SCI using the Electromagnetic Spinal Cord Injury Device (ESCID) developed at Ohio State University (OSU) to induce injury by spinal cord displacement. We used the device to perform mild, moderate and severe injuries (0.80, 0.95, and 1.1 mm displacements, respectively) with a single, brief displacement of <20 msec upon the exposed dorsal surface of the C5 cervical spinal cord of female (180-200 g) Fischer rats. Characterization of the model involved the analysis of the temporal histopathological progression of the injury over 9 weeks using histochemical stains to analyze white and gray mater integrity and immunohistochemistry to examine cellular changes and physiological responses within the injured spinal cord. Accompanying the histological analysis was a comprehensive determination of the behavioral functionality of the animals using a battery of motor tests. Characterization of this novel model is presented to enable and encourage its future use in the design and experimental testing of therapeutic strategies that may be used for human SCI.

    [Purpose] The aim of this study was to evaluate the effect of oscillating electrical field stimulation on motor function recovery and myelin regeneration in rats with spinal cord injury. [Subjects and Methods] A rat model of spinal cord injury was constructed by using the Allen weight-drop method. These rats were randomly divided into normal, spinal cord injury, and spinal cord injury + oscillating electrical field stimulation groups. The experimental group received the intervention with oscillating electrical field stimulation, and the control group received the intervention with an electrical field stimulator without oscillating electrical field stimulation. Each group was then randomly divided into seven subgroups according to observation time (1, 2, 4, 6, 8, 10, and 12 weeks). Basso-Beattie-Bresnahan score and inclined plate test score evaluation, motor evoked potential detection, and histological observation were performed. [Results] In the first 2 weeks of oscillating electrical field stimulation, the oscillating electrical field stimulation and inclined plate test scores of spinal cord injury group and spinal cord injury + oscillating electrical field stimulation group were not significantly different. In the fourth week, the scores of the spinal cord injury group were significantly lower than those of the spinal cord injury + oscillating electrical field stimulation group. The motor evoked potential incubation period in the spinal cord injury + oscillating electrical field stimulation group at the various time points was shorter than that in the spinal cord injury group. In the sixth week, the relative area of myelin in the spinal cord injury + oscillating electrical field stimulation group was evidently larger than that in the spinal cord injury group. [Conclusion] Oscillating electrical field stimulation could effectively improve spinal cord conduction function and promote motor function recovery in rats with spinal cord injury, as well as promote myelin

    To study the effect of hyperbaric oxygen intervention on the microenvironment of nerve regeneration after spinal cord injury modeling and to explore the possible mechanism of nerve regeneration and functional recovery in rats with spinal cord injury. In 98 adult female SD rats, 90 successful models were obtained, which were divided into sham group, spinal cord injury group and hyperbaric oxygen group using randomized block method, 30/group. Spinal cord injury rat model was established in accordance with the modified Allen method. Motor function was assessed at the time points of before modeling, one day, three days, one week, two weeks, three weeks and four weeks after modeling respectively by BBB rating, inclined plane test and improved Tarlov score. At 3 days after modeling, apoptosis of neuronal cells in spinal cord injury region in experimental group was detected by TUNEL method; gene and protein expression of MMP9/2 in spinal cord injury and surrounding tissues was detected by RT-PCR and Western blot assay. At 4 weeks after modeling, histopathological morphological changes in spinal cord injury were observed by HE staining; fluorogold retrograde tracing was used to observe the regeneration and distribution of spinal cord nerve fibers and axon regeneration was observed by TEM. The three motor function scores in hyperbaric oxygen group at each time point after two weeks of treatment were significantly increased compared with spinal cord injury group (P hyperbaric oxygen group were significantly lower than those in spinal cord injury group (P hyperbaric oxygen group was significantly lower (P hyperbaric oxygen group and spinal cord injury group in order; the differences among the groups were statistically significant (P hyperbaric oxygen group; unmyelinated and myelinated nerve fibers in hyperbaric oxygen group were more than those in spinal cord injury group. Hyperbaric oxygen therapy played a protective effect on spinal cord injury through reducing apoptosis of

    Objective: To analyze the data of patients with spinal cord injury (SCI) induced by road traffic crashes in southeastern Iran for better understanding the pattern of these injuries and therefore for better designing health system planning.Methods: In this historical cohort study, the patients who had been transferred to Level I trauma center in southeastern Iran due to road traffic accidents with radiographic documented SCI were evaluated.Results: Among 64 patients with SCI, 38 patients (59.4%, 36 males and 2 females, aged 27.42 years ± 9.44 years on average) were injured by road traffic accidents.Car and motorcycle accidents were responsible for 26 cases (68.4%) and 12 cases (31.6%), respectively. And 31 patients (81. 6%) had complete SCI. Conus medularis (T12-L2) was the most affected level.Conclusions: Results are discussed in terms of preventive measures, specifically those concerning the use of restraint and helmet and driving behavior. This study should be extended nationally to gain a larger case series so that the SCI risk of particular vehicle configurations,considering other crash factors, can be more precisely quantified and the characteristics for low occurrence of SCI can be more precisely identified.

  9. The Potential of Curcumin in Treatment of Spinal Cord Injury

    Full Text Available Current treatment for spinal cord injury (SCI is supportive at best; despite great efforts, the lack of better treatment solutions looms large on neurological science and medicine. Curcumin, the active ingredient in turmeric, a spice known for its medicinal and anti-inflammatory properties, has been validated to harbor immense effects for a multitude of inflammatory-based diseases. However, to date there has not been a review on curcumin’s effects on SCI. Herein, we systematically review all known data on this topic and juxtapose results of curcumin with standard therapies such as corticosteroids. Because all studies that compare the two show superior results for curcumin over corticosteroids, it could be true that curcumin better acts at the inflammatory source of SCI-mediated neurological injury, although this question remains unanswered in patients. Because curcumin has shown improvements from current standards of care in other diseases with few true treatment options (e.g., osteoarthritis, there is immense potential for this compound in treating SCI. We critically and systematically summarize available data, discuss clinical implications, and propose further testing of this well-tolerated compound in both the preclinical and the clinical realms. Analyzing preclinical data from a clinical perspective, we hope to create awareness of the incredible potential that curcumin shows for SCI in a patient population that direly needs improvements on current therapy.

    Spinal cord injury (SCI) in adult rats initiates a cascade of events producing a nonpermissive environment for axonal regeneration. This nonfavorable environment could be due to the expression of repulsive factors. The Eph receptor protein tyrosine kinases and their respective ligands (ephrins) are families of molecules that play a major role in axonal pathfinding and target recognition during central nervous system (CNS) development. Their mechanism of action is mediated by repellent forces between receptor and ligand. The possible role that these molecules play after CNS trauma is unknown. We hypothesized that an increase in the expression of Eph proteins and/or ephrins may be one of the molecular cues that restrict axonal regeneration after SCI. Rats received a contusive SCI at T10 and in situ hybridization studies 7 days posttrauma demonstrated: (i) a marked up-regulation of Eph B3 mRNA in cells located in the white matter at the lesion epicenter, but not rostral or caudal to the injury site, and (ii) an increase in Eph B3 mRNA in neurons in the ventral horn and intermediate zone of the gray matter, rostral and caudal to the lesion. Immunohistochemical analyses localizing Eph B3 protein were consistent with the mRNA results. Colocalization studies performed in injured animals demonstrated increased Eph B3 expression in white matter astrocytes and motor neurons of the gray matter. These results suggest that Eph B3 may contribute to the unfavorable environment for axonal regeneration after SCI. Copyright 1999 Academic Press.

    2015-01-01

    Spinal cord injury (SCI) is a devastating condition that produces signiifcant changes in the life-style of patients. Many molecular and cellular events are triggered after the initial physical impact to the cord. Two major phases have been described in the ifeld of SCI: an acute phase and late phase. Most of the therapeutic strategies are focused on the late phase because this provides an opportunity to target cellular events like apoptosis, demyelination, scar formation and axonal outgrowth. In this mini-review, we will focus on two agents (tamoxifen and a Src kinase family inhibitor known as PP2) that have been shown in our laboratory to produce neuroprotective (increase cell survival) and/or regenerative (axonal outgrowth) actions. The animal model used in our laboratory is adult female rat (~250 g) with a moderate contusion (12.5 mm) to the spinal cord at the T10 level, using the MASCIS impactor device. Tamoxifen or PP2 was administered by implantation of a 15 mg pellet (Innovative Research of America, Sarasota, FL, USA) or by intraperitoneal injections (1.5 mg/kg, every 3 days), respectively, to produce a long-term effect (28 days). Tamoxifen and the Src kinase inhibitor, PP2, are drugs that in rats with a moderate spinal cord injury promote functional locomotor recovery, increase spared white matter tissue, and stimulate axonal outgrowth. Moreover, tamoxifen reduces the formation of reactive oxygen species. Therefore, these drugs are possible therapeutic agents that have a neuroprotective/regen-erative activity in vertebrates with SCI.

    2016-05-01

    Full Text Available Traumatic spinal cord injuries (SCIs affect 1.3 million North Americans, producing devastating physical, social, and vocational impairment. Pathophysiologically, the initial mechanical trauma is followed by a significant secondary injury which includes local ischemia, pro-apoptotic signaling, release of cytotoxic factors, and inflammatory cell infiltration. Expedient delivery of medical and surgical care during this critical period can improve long-term functional outcomes, engendering the concept of “Time is Spine”. We emphasize the importance of expeditious care while outlining the initial clinical and radiographic assessment of patients. Key evidence-based early interventions (surgical decompression, blood pressure augmentation, and methylprednisolone are also reviewed, including findings of the landmark Surgical Timing in Acute Spinal Cord Injury Study (STASCIS. We then describe other neuroprotective approaches on the edge of translation such as the sodium-channel blocker riluzole, the anti-inflammatory minocycline, and therapeutic hypothermia. We also review promising neuroregenerative therapies that are likely to influence management practices over the next decade including chondroitinase, Rho-ROCK pathway inhibition, and bioengineered strategies. The importance of emerging neural stem cell therapies to remyelinate denuded axons and regenerate neural circuits is also discussed. Finally, we outline future directions for research and patient care.

    The treatment of spinal cord injury by using implants that provide a permissive environment for axonal growth is in the focus of the research for regenerative therapies. Here, Raman-based label-free techniques were applied for the characterization of morphochemical properties of surgically induced spinal cord injury in the rat that received an implant of soft unfunctionalized alginate hydrogel. Raman microspectroscopy followed by chemometrics allowed mapping the different degenerative areas, while multimodal multiphoton microscopy (e.g. the combination of coherent anti-Stokes Raman scattering (CARS), endogenous two-photon fluorescence and second harmonic generation on the same platform) enabled to address the morphochemistry of the tissue at cellular level. The regions of injury, characterized by demyelination and scarring, were retrieved and the distribution of key tissue components was evaluated by Raman mapping. The alginate hydrogel was detected in the lesion up to six months after implantation and had positive effects on the nervous tissue. For instance, multimodal multiphoton microscopy complemented the results of Raman mapping, providing the micromorphology of lipid-rich tissue structures by CARS and enabling to discern lipid-rich regions that contained myelinated axons from degenerative regions characterized by myelin fragmentation and presence of foam cells. These findings demonstrate that Raman-based imaging methods provide useful information for the evaluation of alginate implant effects and have therefore the potential to contribute to new strategies for monitoring degenerative and regenerative processes induced in SCI, thereby improving the effectiveness of therapies.

    2014-01-01

    Technological advances have helped to improve functional ability in spinal cord injury survivors. The aim of this study is to systematically review the evidence for functional electrical stimulation (FES) on functional tasks involving the upper limb in people with spinal cord injuries. The authors systematically searched from September 2009 to September 2014 in relevant databases using a combination of keywords covering spinal cord injury and FES. Studies were selected using pre-determined criteria. The search yielded 144 studies. Only five studies met the inclusion criteria. All five reported improvements immediately and at follow-up in functional ability as a result of FES or FES combined with conventional therapy. There is some preliminary evidence that FES may reduce disability due to upper limb-related activity limitations in tetraplegic spinal cord injury. Further work needs to examine the role of FES in more detail and in combination with other treatments.

    Stem cell transplantation can promote functional restoration following acute spinal cord injury (injury time 6 months) were treated with human umbilical cord blood stem cells via intravenous and intrathecal injection. The follow-up period was 12 months after transplantation. Results found that autonomic nerve functions were restored and the latent period of somatosensory evoked potentials was reduced. There were no severe adverse reactions in patients following stem cell transplantation. These experimental findings suggest that the transplantation of human umbilical cord blood stem cells is a safe and effective treatment for patients with traumatic spinal cord injury.

    To describe group therapy utilization in spinal cord injury (SCI) inpatient rehabilitation. Prospective observational study. Six inpatient rehabilitation facilities. Patients (N=1376) receiving initial rehabilitation after traumatic SCI. Not applicable. Time spent in group versus individual therapy for physical therapy (PT), occupational therapy (OT), therapeutic recreation (TR), and psychology (PSY) therapies. The majority (98%) of patients participated in at least 1 group therapy session, with 83%, 81%, 80%, and 54% of patients receiving group PT, OT, TR, and PSY, respectively. On average, 24% of treatment sessions and 27% of treatment time was provided in group sessions, with TR providing the greatest percent of its time in groups. Group therapy time and time spent in specific activities varied among patient subgroups with different injury characteristics. Group therapy time also varied widely among centers (range, 1.2-6.6h/wk). Across all injury subgroups, individual and group therapy hours per week were negatively correlated for OT and positively correlated for TR. Patient characteristics, clinician experience, and treatment center predicted 32% of variance in group hours per week. PT and OT strengthening/endurance interventions and TR outings were the most common group activities overall. While the majority of inpatient SCI rehabilitation consists of individual sessions, most patients participate in group therapy, which contributes significantly to total therapy time. Patterns of group utilization fit with functional expectations and clinical goals. A trade-off between group and individual therapy may occur in some disciplines. Utilization of group therapy varies widely among centers, and further study is needed to identify optimal patterns of group therapy utilization.

    Spinal cord injury (SCI) is one of the most serious disorders in clinics, and the high disability rate and functional deficits are common issues in patients. Transplantation of bone-marrow-derived mesenchymal stromal cells (BMSCs) into the injured spinal cord is emerging as a novel method in the therapeutics of SCI; however, its application is limited by the poor survival rate of the transplanted cells and low differentiation rate into neurons. Our laboratory recently reported that electrical stimulation (ES) dramatically improves the survival rate of transplanted BMSCs and increases spinal cord functions in animals with spinal cord injury. In this paper, we asked whether implanted electro-acupuncture (iEA) can advance the beneficial effects from the ES treatment in animals with spinal cord injury. We showed that BMSCs transplantation alone resulted in significant functional recovery in animals. Interestingly, iEA with BMSCs treatment induced a significantly higher functional improvement in locomotor functions and SSEP compared to the BMSCs treatment alone. Additionally, we used molecular biology techniques and showed that BMSCs transplantation with iEA treatment significantly increased the number of surviving BMSCs compared to the BMSCs alone group. In conclusion, our experiment showed that the approach of coupling iEA electric stimulation and BMSCs transplantation remarkably promotes functional improvements in animals with spinal cord injury and holds promising potential to treat spinal cord injury in humans.

    Emerging studies of treating spinal cord injury (SCI) with adult stem cells led us to evaluate the effects of transplantation of hair fol icle stem cells in rats with a compression-induced spinal cord lesion. Here, we proposed a hypothesis that rat hair fol icle stem celltransplantation can promote the recovery of injured spinal cord. Compression-induced spinal cord injury was induced in Wistar rats in this study. The bulge area of the rat vibrissa fol icles was isolated, cultivated and characterized with nestin as a stem cellmarker. 5-Bromo-2′-deoxyuridine (BrdU) labeled bulge stem cells were transplanted into rats with spinal cord injury. Immunohistochemical staining results showed that some of the grafted cells could survive and differentiate into oligodendrocytes (receptor-interacting protein positive cells) and neuronal-like cells (βIII-tubulin positive cells) at 3 weeks after transplantation. In addition, recovery of hind limb locomotor function in spinal cord injury rats at 8 weeks fol owing celltransplantation was assessed using the Basso, Beattie and Bresnahan (BBB) locomotor rating scale. The results demon-strate that the grafted hair fol icle stem cells can survive for a long time period in vivo and differentiate into neuronal- and glial-like cells. These results suggest that hair fol icle stem cells can promote the recovery of spinal cord injury.

    During the transition from acute to chronic stages of recovery after spinal cord injury (SCI), there is an evolving state of immunologic dysfunction that exacerbates the problems associated with the more clinically obvious neurologic deficits. Since injury directly affects cells embedded within the “immune privileged/specialized” milieu of the spinal cord, maladaptive or inefficient responses are likely to occur. Collectively, these responses qualify as part of the continuum of “SCI disease” ...

Tomography was available for 25 patients, and flexion-extension lateral views for 28patients, CT scanning for 21 patients, MRI for 26 patients.Results: Of these patients, 46 patients were identified with injuries of upper cervical spine (9 with atlantal arch fracture, seven with axial fracture, 21 with odontoid fracture, 1 with atlantal arch fracture combining with odontoid fracture, and 1 with atlantal transverse ligament disruption); 7 patients sustained injuries of lower cervical spine (3 fractures of vertebral body, 2 dislocations and 6fracture-dislocations ); 2 patients had multiple noncontiguous cervical injuries; and 3 had cervical spinal cord injury without radiographic abnormalities (SCIWORA).Conclusions: Imaging assessment is of great importance in the diagnosis of cervical spine and spinal cord injuries in children. Whenever cervical spine and spinal cord injuries are suspected for children patients, and the three-views should be routinely indicated. MRI should be routinely performed in all children with cervical SCIWORA.

    To examine the effects of transcutaneous spinal cord stimulation (tSCS) on lower-limb spasticity. Interventional pilot study to produce preliminary data. Department of Physical Medicine and Rehabilitation, Wilhelminenspital, Vienna, Austria. Three subjects with chronic motor-incomplete spinal cord injury (SCI) who could walk ≥10 m. Two interconnected stimulating skin electrodes (Ø 5 cm) were placed paraspinally at the T11/T12 vertebral levels, and two rectangular electrodes (8 × 13 cm) on the abdomen for the reference. Biphasic 2 ms-width pulses were delivered at 50 Hz for 30 minutes at intensities producing paraesthesias but no motor responses in the lower limbs. The Wartenberg pendulum test and neurological recordings of surface-electromyography (EMG) were used to assess effects on exaggerated reflex excitability. Non-functional co-activation during volitional movement was evaluated. The timed 10-m walk test provided measures of clinical function. The index of spasticity derived from the pendulum test changed from 0.8 ± 0.4 pre- to 0.9 ± 0.3 post-stimulation, with an improvement in the subject with the lowest pre-stimulation index. Exaggerated reflex responsiveness was decreased after tSCS across all subjects, with the most profound effect on passive lower-limb movement (pre- to post-tSCS EMG ratio: 0.2 ± 0.1), as was non-functional co-activation during voluntary movement. Gait speed values increased in two subjects by 39%. These preliminary results suggest that tSCS, similar to epidurally delivered stimulation, may be used for spasticity control, without negatively impacting residual motor control in incomplete SCI. Further study in a larger population is warranted.

    Full Text Available This case present a rare forensic case of cervical spinal gunshot injury of a female by her husband, a professional hunter, during a family fight with a shotgun fire pellets. The gunshot destroyed completely the cervical spinal cord, without injury to the neck vessels and organs and with the patient survival for seven days. We discuss notions of judicial ballistics, assessment of the patient with spinal cord gunshot injury and therapeutic strategies. Even if cervical spine gunshot injuries are most of the times lethal for majority of patients, the surviving patients need the coordination of a multidisciplinary surgical team to ensure the optimal functional prognostic.

    To evaluate recreational and medical cannabis use in individuals with traumatic spinal cord injury, including reasons and predictors for use, perceived benefits and negative consequences. Cross-sectional survey in Denmark. A 35-item questionnaire was sent to 1,101 patients with spinal cord injury who had been in contact with a rehabilitation centre between 1990 and 2012. A total of 537 participants completed the questionnaire. Of these, 36% had tried cannabis at least once and 9% were current users. Of current users, 79% had started to use cannabis before their spinal cord injury. The main reason for use was pleasure, but 65% used cannabis partly for spinal cord injury-related consequences and 59% reported at least good effect on pain and spasticity. Negative consequences of use were primarily inertia and feeling quiet/subdued. Lower age, living in rural areas/larger cities, tobacco-smoking, high alcohol intake and higher muscle stiffness were significantly associated with cannabis use. Those who had never tried cannabis reported that they would mainly use cannabis to alleviate pain and spasticity if it were legalized. Cannabis use is more frequent among individuals with spinal cord injury in Denmark than among the general population. High muscle stiffness and various demographic characteristics (lower age, living in rural areas/larger cities, tobacco-smoking and high alcohol intake) were associated with cannabis use. Most participants had started using cannabis before their spinal cord injury. There was considerable overlap between recreational and disability-related use.

    Full Text Available Introduction: Blast induced neurotrauma has been the signature wound in returning soldiers from the ongoing wars in Iraq and Afghanistan. Of importance is understanding the pathomechansim(s of blast overpressure (OP induced axonal injury. Although several recent animal models of blast injury indicate the neuronal and axonal injury in various brain regions, animal studies related to axonal injury in the white matter (WM tracts of cervical spinal cord are limited. Objective: The purpose of this study was to assess the extent of axonal injury in WM tracts of cervical spinal cord in male Sprague Dawley rats subjected to a single insult of blast OP. Materials and Methods: Sagittal brainstem sections and horizontal cervical spinal cord sections from blast and sham animals were stained by neurofilament light (NF-L chain and beta amyloid precursor protein immunocytochemistry and observed for axonal injury changes. Results: Observations from this preliminary study demonstrate axonal injury changes in the form of prominent swellings, retraction bulbs, and putative signs of membrane disruptions in the brainstem and cervical spinal cord WM tracts of rats subjected to blast OP. Conclusions: Prominent axonal injury changes following the blast OP exposure in brainstem and cervical spinal WM tracts underscores the need for careful evaluation of blast induced injury changes and associated symptoms. NF-L immunocytochemistry can be considered as an additional tool to assess the blast OP induced axonal injury.

    1. After traumatic spinal cord injury (SCI), histological and neurological consequences are developing for several days and even weeks. However, little is known about the dynamics of changes in spinal axonal conductivity. The aim of this study was to record and compare repeated spinal cord evoked potentials (SCEP) after SCI in the rat during a 4 weeks' interval. These recordings were used: (i) for studying the dynamics of functional changes in spinal axons after SCI, and (ii) to define the value of SCEP as an independent outcome parameter in SCI studies. 2. We have used two pairs of chronically implanted epidural electrodes for stimulation/recording. The electrodes were placed below and above the site of injury, respectively. Animals with implanted electrodes underwent spinal cord compression injury induced by epidural balloon inflation at Th8-Th9 level. There were five experimental groups of animals, including one control group (sham-operated, no injury), and four injury groups (different degrees of SCI). 3. After SCI, SCEP waveform was either significantly reduced or completely lost. Partial recovery of SCEPs was observed in all groups. The onset and extent of recovery clearly correlated with the severity of injury. There was good correlation between quantitated SCEP variables and the volumes of the compressing balloon. However, sensitivity of electropohysiological parameters was inferior compared to neurological and morphometric outcomes. 4. Our study shows for the first time, that the dynamics of axonal recovery depends on the degree of injury. After mild injury, recovery of signal is rapid. However, after severe injury, axonal conductivity can re-appear after as long as 2 weeks postinjury. In conclusion, SCEPs can be used as an independent parameter of outcome after SCI, but in general, the sensitivity of electrophysiological data were worse than standard morphological and neurological evaluations.

    Despite the relatively low incidence, the management and care of persons with traumatic spinal cord injury (tSCI) can be resource intensive and complex, spanning multiple phases of care and disciplines. Using a simulation model built with a system level view of the healthcare system allows for prediction of the impact of interventions on patient and system outcomes from injury through to community reintegration after tSCI. The Access to Care and Timing (ACT) project developed a simulation model for tSCI care using techniques from operations research and its development has been described previously. The objective of this article is to briefly describe the methodology and the application of the ACT Model as it was used in several of the articles in this focus issue. The approaches employed in this model provide a framework to look into the complexity of interactions both within and among the different SCI programs, sites and phases of care.

    No known research addresses the effects of yoga in those with spinal cord injury (SCI), yet yoga has the potential to improve many impairments commonly associated with SCI. This case report documents the outcomes of a yoga program in an individual with an SCI. The participant was a 59-year-old male who sustained an incomplete C3-C6 SCI. He practiced Hatha yoga for 60-min sessions, twice per week for 12 weeks and despite neurological injury, was able to complete a yoga program with modifications. Improvements were noted in balance; endurance; flexibility; posture; muscle strength of the hip extensors, hip abductors and knee extensors; and in performance of functional goals. No changes were noted in gait velocity, satisfaction in performance of goals or in overall quality of life. The participant was able to practice yoga even though he used an assistive device to walk.

    To describe the MR manifestations and temporal course of wallerian degeneration that occurs above and below a spinal cord injury, and to compare the MR findings with postmortem histopathology. Twenty-four postmortem spinal cords from patients with cervical (n = 14), thoracic (n = 6), and lumbar (n = 4) cord injuries were studied with axial T1- and T2-weighted spin-echo MR imaging. Injury-to-death intervals varied from 8 days to 23 years. The images were examined for alteration of signal above and below the injury site. Histologic studies of these cords with axon, myelin, and connective tissue stains were performed at levels equivalent to the MR sections. Immunohistochemical analysis using antibodies to glial fibrillary acetic protein was also performed on 19 cords. Pathologic-imaging comparisons were made. MR images showed increased signal intensity in the dorsal columns above the injury level and in the lateral corticospinal tracts below the injury level in all cases in which cord injury had occurred 7 or more weeks before death. In early postinjury survival times (8 days and 12 days) MR findings were normal; histologically there was early wallerian degeneration in only the dorsal columns at 8 days and in both the lateral and dorsal columns at 12 days. MR showed wallerian degeneration in all cases examined at 7 weeks after injury and thereafter. Wallerian degeneration was demonstrated by histology and MR in all specimens in which the injury-to-death interval was greater than 7 weeks. Recognition of wallerian degeneration on MR allows complete analysis of the injury, explains abnormal MR signals at sites remote from the epicenter of the injury, and may be useful in the future in the timing and planning of therapeutic interventions.

    Autonomic dysreflexia (AD) is a well-documented complication of spinal cord injury (SCI) at or above the T6 level. However, research into AD has focused primarily on the adult. Because research that involves children with SCI is scarce, current guidelines may not be appropriate for children. Therefore, many episodes of AD may be unrecognized or inappropriately treated. To address this issue, Shriners Hospitals for Children undertook the development of a protocol specific to children and adolescents. A task force was developed to look at current literature on AD and blood pressure in children. Utilizing this literature and consensus among the task force members, the tools necessary to treat children with SCI at risk for AD were developed. The task force developed several products intended to assist in the recognition and management of AD. These include an event flow sheet for recording incidents of AD, a letter for the child's school or primary care physician that provides a brief summary of AD and the child's baseline blood pressure, and a policy/protocol with 2 age-specific algorithms to standardize interventions across the 3 Shriners Hospitals in the United States with SCI programs (California, Illinois, and Pennsylvania). The Shriners Hospitals for Children Task Force on Autonomic Dysreflexia in Children with Spinal Cord Injury has developed several tools specific to children. However, many questions remain to be answered concerning blood pressure norms and the clinical presentation of AD in children.

  12. Does being female provide a neuroprotective advantage following spinal cord injury?

    Full Text Available It has been controversial whether gender has any effect on recovery following spinal cord injury (SCI. Past experimental and clinical research aimed at addressing this subject has led to constrasting findings on whether females hold any advantage in locomotor recovery. Additionally, for studies supporting the notion of a female gender related advantage, a definite cause has not been explained. In a recent study, using large sample sizes for comparative male and female spinal cord injury cohorts, we reported that a significant gender advantage favoring females existed in both tissue preservation and functional recovery after taking into consideration discrepancies in age and weight of the animals across sexes. Prior animal research frequently used sample sizes that were too small to determine significance with certainty and also did not account for two other factors that influence locomotor performance: age and weight. Our finding is important in light of controversy surrounding the effect of gender on outcome and the fact that SCI affects more than ten thousand new individuals annually, a population that is disproportionately male. By deepening our understanding of why a gender advantage exists, potential new therapeutics can be designed to improve recovery for the male population following the initial trauma or putatively augment the neuroprotective privilege in females for enhanced outcomes.

    Interleukin-33 (IL-33) is a member of the interleukin-1 cytokine family and highly expressed in the naïve mouse brain and spinal cord. Despite the fact that IL-33 is known to be inducible by various inflammatory stimuli, its cellular localization in the central nervous system and role in pathological conditions is controversial. Administration of recombinant IL-33 has been shown to attenuate experimental autoimmune encephalomyelitis progression in one study, yet contradictory reports also exist. Here we investigated for the first time the pattern of IL-33 expression in the contused mouse spinal cord and demonstrated that after spinal cord injury (SCI) IL-33 was up-regulated and exhibited a nuclear localization predominantly in astrocytes. Importantly, we found that treatment with recombinant IL-33 alleviated secondary damage by significantly decreasing tissue loss, demyelination and astrogliosis in the contused mouse spinal cord, resulting in dramatically improved functional recovery. We identified both central and peripheral mechanisms of IL-33 action. In spinal cord, IL-33 treatment reduced the expression of pro-inflammatory tumor necrosis factor-alpha and promoted the activation of anti-inflammatory arginase-1 positive M2 microglia/macrophages, which chronically persisted in the injured spinal cord for up to at least 42 days after the treatment. In addition, IL-33 treatment showed a tendency towards reduced T-cell infiltration into the spinal cord. In the periphery, IL-33 treatment induced a shift towards the Th2 type cytokine profile and reduced the percentage and absolute number of cytotoxic, tumor necrosis factor-alpha expressing CD4+ cells in the spleen. Additionally, IL-33 treatment increased expression of T-regulatory cell marker FoxP3 and reduced expression of M1 marker iNOS in the spleen. Taken together, these results provide the first evidence that IL-33 administration is beneficial after CNS trauma. Treatment with IL33 may offer a novel therapeutic

    Study Design  Systematic review. Objective  To determine the incidence, pathogenesis, and clinical outcomes related to neurogenic fevers following traumatic spinal cord injury (SCI). Methods  A systematic review of the literature was performed on thermodysregulation secondary to acute traumatic SCI in adult patients. A literature search was performed using PubMed (MEDLINE), Cochrane Central Register of Controlled Trials, and Scopus. Using strict inclusion and exclusion criteria, seven relevant articles were obtained. Results  The incidence of fever of all origins (both known and unknown) after SCI ranged from 22.5 to 71.7% with a mean incidence of 50.6% and a median incidence of 50.0%. The incidence of fever of unknown origin (neurogenic fever) ranged from 2.6 to 27.8% with a mean incidence of 8.0% and a median incidence of 4.7%. Cervical and thoracic spinal injuries were more commonly associated with fever than lumbar injuries. In addition, complete injuries had a higher incidence of fever than incomplete injuries. The pathogenesis of neurogenic fever after acute SCI is not thoroughly understood. Conclusion  Neurogenic fevers are relatively common following an acute SCI; however, there is little in the scientific literature to help physicians prevent or treat this condition. The paucity of research underscored by this review demonstrates the need for further studies with larger sample sizes, focusing on incidence rate, clinical outcomes, and pathogenesis of neurogenic fever following acute traumatic SCI.

    Nonspecific neuronal activity elicited by intraspinal microstimulation in the intermediate and ventral gray matter of thoracic spinal segments caudal to a complete spinal cord transection significantly increased the rat hindlimb Basso,Beattie,Bresnahan locomotor score by activating the central pattern generator located in the lumbar spinal cord.However,the best region for intraspinal microstimulation is unclear.Using an incomplete spinal cord injury model at T8,we compared the use of intraspinal microstimulation to activate the spinal cord in rats with a spontaneous recovery group.The intraspinal microstimulation group recovered sooner and showed three kinds of movement: the left hindlimb,the left hindlimb toes,and the paraspinal muscles and tails.These had different microstimulation thresholds.There was mild hyperplasia of the astrocytes surrounding the tips of the microelectrodes and slight inflammatory reactions nearby.These results indicate that implantation of microelectrodes was relatively safe and induced minimal damage to the lumbar-sacral spinal cord.Intraspinal microstimulation in the lumbar sacral spinal cord may improve leg movements after spinal cord injury.Non-specific intraspinal microstimulation may be a novel technique for the recovery of spinal cord injuries.

    There are many reports describing gross anatomical and microscopical findings of severely injured cervical cords in autopsy of the acute and chronic state, but no morphological findings of a severe cervical spinal cord injury in a chronic state by follow-up CT myelography have been found in the literature so far. The sagittal and transverse diameters of the cervical spinal cord and subarachnoid space of 9 out of 14 severe cervical spinal cord injury patients were measured with CT myelography within 7.5 years after the tranuma and their size compared with a control group which was made up of 29 patients with slight radiculopathy due to cervical spondylosis and whiplash injuries. Injured cord levels were C4 4 cases, C5 4 cases and C6 1 case. Remarkable spinal cord atrophy was recogniged in the sagittal diameter from C1 to C7 and in the transverse diameter below C4 and narrowing of the cervical subarachnoid space in the sagittal diameter from C2 to C5. The significance level was set at 1 - 5 %. From these fingings, we have concluded that atrophy appeared not only in the injured segment but also the whole cervical cord after the trauma. There was less cord atrophy in a good functional prognosis than in a poor prognosis.

    A rat model of spinal cord injury was established using modified Allen's method and treated with the ferric iron-chelating agent, deferoxamine. Hematoxylin-eosin, Nissl and Perl's Prussian blue staining, at 7-14 days following spinal cord injury, showed that following deferoxamine treatment, glial cells proliferation increased significantly, nerve cell morphology was improved and hemosiderin was significantly reduced in the injury region. At 1-56 days following injury, Basso, Beattie, and Bres nahan Locomotor Rating Scale scores were increased, while latencies of somatosensory-evoked potentials and motor-evoked potentials were decreased. Results demonstrate that deferoxamine can promote neurological functional recovery after experi-mental spinal cord injury in rats.

    A 10-year review (1987-1996) of injuries sustained to the spine and spinal cord in rugby players with resultant paralysis has been undertaken. This article reviews that the incidence of serious rugby spine and spinal cord injuries in South Africa has increased over the 10-year period reviewed, despite stringent new rules instituted in an attempt to decrease the incidence of these injuries. The mechanisms of injury, as previously reported, remain the same as well as the phases of game responsible for injury of the tight scrum, tackle, rucks, and mauls. Two new observations are reported: the first is related to the occurrence of spinal cord concussion with transient paralysis, and the second is related to the increased incidence of osteoarthritis of the cervical spine in rugby players.

    We describe the changes exhibited by astrocytes in areas of Wallerian degeneration after spinal cord injury in humans using glial fibrillary acidic protein immunohistochemistry correlated to standard histology at time points ranging from 8 days to 23 years after injury. Astrocytes were slow to react; a slight increase in immunoreactivity was observed at 4 months. Over time they began to lose immunoreactivity in both the somata and the processes as the debris from the degenerative process was cleared. By 1 year after injury the staining intensity had decreased to levels which were lower than in normal areas of the cord. This hypointense staining persisted for at least 23 years after injury. These findings are significantly different from those observed in animal studies and emphasize the need for additional pathological studies of human spinal cord injury.

    Full Text Available Spinal lesions substantially impair ambulation, occur generally in young and otherwise healthy individuals, and result in devastating effects on quality of life. Restoration of locomotion after damage to the spinal cord is challenging because axons of the damaged neurons do not regenerate spontaneously. Body-weight-supported treadmill training (BWSTT is a therapeutic approach in which a person with a spinal cord injury (SCI steps on a motorized treadmill while some body weight is removed through an upper body harness. BWSTT improves temporal gait parameters, muscle activation patterns, and clinical outcome measures in persons with SCI. These changes are likely the result of reorganization that occurs simultaneously in supraspinal and spinal cord neural circuits. This paper will focus on the cortical control of human locomotion and motor output, spinal reflex circuits, and spinal interneuronal circuits and how corticospinal control is reorganized after locomotor training in people with SCI. Based on neurophysiological studies, it is apparent that corticospinal plasticity is involved in restoration of locomotion after training. However, the neural mechanisms underlying restoration of lost voluntary motor function are not well understood and translational neuroscience research is needed so patient-orientated rehabilitation protocols to be developed.

Electrical stimulation might facilitate plastic changes in affected spinal circuitries that may be beneficial in improving motor function and spasticity or SCI-related neuropathic pain. Based on available animal and clinical evidence, we critically reviewed the physiological basis and therapeutic action of transcutaneous spinal cord stimulation in SCI. We analyzed the literature published on PubMed to date, looking for the role of three main noninvasive stimulation techniques in the recovery process of SCI and focusing mainly on transcutaneous spinal stimulation. This review discusses the main clinical applications, latest advances, and limitations of noninvasive electrical stimulation of the spinal cord. Although most recent research in this topic has focused on transcutaneous spinal direct current stimulation (tsDCS, we also reviewed the technique of transcutaneous electric nerve stimulation (TENS and neuromuscular electrical stimulation (NMES as potential methods to modulate spinal cord

    Fluorescent imaging technique is a promising method and has been developed for in vivo applications in cellular biology. In particular, nonlinear optical imaging technique, multi-photon microscopy has make it possible to analyze deep portion of tissues in living animals such as axons of spinal code. Traumatic spinal cord injuries (SCIs) are usually caused by contusion damages. Therefore, observation of spinal cord tissue after the contusion injury is necessary for understanding cellular dynamics in response to traumatic SCI and development of the treatment for traumatic SCI. Our goal is elucidation of mechanism for degeneration of axons after contusion injuries by establishing SCI model and chronic observation of injured axons in the living animals. Firstly we generated and observed acute SCI model by contusion injury. By using a multi-photon microscope, axons in dorsal cord were visualized approximately 140 micron in depth from the surface. Immediately after injury, minimal morphological change of spinal cord was observed. At 3 days after injury, spinal cord was swelling and the axons seem to be fragmented. At 7 days after injury, increased degradation of axons could be observed, although the image was blurred due to accumulation of the connective tissue. In the present study, we successfully observed axon degeneration after the contusion SCI in a living animal in vivo. Our final goal is to understand molecular mechanisms and cellular dynamics in response to traumatic SCIs in acute and chronic stage.

    This double-blind, sham-controlled, crossover case study combined transvertebral direct current stimulation (tvDCS) and locomotor training on a robot-assisted gait orthosis (LT-RGO). Determine whether cathodal tvDCS paired with LT-RGO leads to greater changes in function and neuroplasticity than sham tvDCS paired with LT-RGO. University of Kentucky (UK) HealthCare Stroke and Spinal Cord Neurorehabilitation Research at HealthSouth Cardinal Hill Hospital. A single subject with motor incomplete spinal cord injury (SCI) participated in 24 sessions of sham tvDCS paired with LT-RGO before crossover to 24 sessions of cathodal tvDCS paired with LT-RGO. Functional outcomes were measured with 10 Meter Walk Test (10MWT), 6 Minute Walk Test (6MWT), Spinal Cord Independence Measure-III (SCIM-III) mobility component, lower extremity manual muscle test (MMT), and Berg Balance Scale (BBS). Corticospinal changes were assessed using transcranial magnetic stimulation. Improvement in 10MWT speed, SCIM-III mobility component, and BBS occurred with both conditions. 6MWT worsened after sham tvDCS and improved after cathodal tvDCS. MMT scores for both lower extremities improved following sham tvDCS but decreased following cathodal tvDCS. Corticospinal excitability increased following cathodal tvDCS but not sham tvDCS. These results suggest that combining cathodal tvDCS and LT-RGO may improve functional outcomes, increase corticospinal excitability, and possibly decrease spasticity. Randomized controlled trials are needed to confirm these conclusions.

    Identifying clinical neuropathic pain phenotypes is a first step to better understand the underlying pain mechanisms after spinal cord injury (SCI). The primary purpose of the present study was to characterize multidimensional neuropathic pain phenotypes based on quantitative sensory testing (QST), pain intensity, and utilization of catastrophizing coping strategies. Thermal perception, thermal pain, and vibratory perception thresholds were assessed above and below the level of injury (LOI) in 101 persons with SCI and neuropathic pain, 18 persons with SCI and no neuropathic pain, and 50 able-bodied, pain-free controls. Cluster analysis of QST z-scores below the LOI, pain intensity ratings, and the Coping Strategies Questionnaire (CSQ) catastrophizing subscale scores in subjects with neuropathic pain resulted in two phenotypes: severe neuropathic pain (SNP) with greater pain intensity (7.39 ± 1.57) and thermal and vibratory sensitivity compared with the moderate neuropathic pain (MNP; 5.40 ± 1.43). A factor analysis including all CSQ subscales, the Neuropathic Pain Symptom Inventory (NPSI) total score, and thermal pain sensitivity above and below the LOI resulted in three factors: (1) adaptive pain coping including increasing activities, diverting attention, and reinterpreting pain sensations; (2) catastrophizing, neuropathic pain, and thermal sensitivity including greater NPSI total score, thermal pain sensitivity below the LOI, and catastrophizing; and (3) general pain sensitivity including greater thermal pain sensitivity above the LOI and lower catastrophizing. Our results suggest that neuropathic pain symptom severity post-SCI is significantly associated with residual spinothalamic tract function below the LOI and catastrophizing pain coping.

    Full Text Available Background: Mortality rates from injuries are higher for people from poorer economic backgrounds than those with higher incomes (according to the World Health Organization [WHO], and health care professionals and organisations dealing with people with disabilities experience that individuals with spinal cord injury (SCI in low income countries face serious challenges in their daily lives.Objectives: The aims of this study were to explore life expectancy (life expectancy is the average remaining years of life of an individual and the situation of persons living with SCI in low income settings.Method: Literature studies and qualitative methods were used. Qualitative data was collected through semi-structured interviews with 23 informants from four study sites in Zimbabwe representing persons with SCI, their relatives and rehabilitation professionals.Results: There are few publications available about life expectancy and the daily life of persons with SCI in low income countries. Those few publications identified and the study findings confirm that individuals with SCI are experiencing a high occurrence of pressure sores and urinary tract infections leading to unnecessary suffering, often causing premature death. Pain and depression are frequently reported and stigma and negative attitudes are experienced in society. Lack of appropriate wheelchairs and services, limited knowledge about SCI amongst health care staff, limited access to health care and rehabilitation services, loss of employment and lack of financial resources worsen the daily challenges.Conclusion: The study indicates that life expectancy for individuals with SCI in low income settings is shorter than for the average population and also with respect to individuals with SCI in high income countries. Poverty worsened the situation for individuals with SCI, creating barriers that increase the risk of contracting harmful pressure sores and infections leading to premature death. Further

    A limitation of many studies of non-traumatic spinal cord injury (NT-SCI) and traumatic spinal cord injury (T-SCI) is potential lack of generalizability because of selection bias. An open cohort study using a national rehabilitation database was planned to address this. To compare the demographic characteristics and outcomes between NT-SCI and T-SCI patients. Rehabilitation hospitals in Australia. The Australasian Rehabilitation Outcomes Centre maintains a national database of information on in-patients admitted to almost all (130/145 as at 2006) public and private rehabilitation hospitals in Australia. It collects a range of demographic and clinical outcomes. Patients were included if they were discharged between 1 January 2002 and 31 December 2006. Patients were excluded if they were admitted for <7 days, only for assessment or were a readmission. There were 3610 patients included (NT-SCI, n=2241, 62.1%; T-SCI, n=1361, 37.7%). There were numerous significant differences between NT-SCI and T-SCI patients. NT-SCI patients were generally older (median age NT-SCI 67 years vs T-SCI 46 years, P=0.000), less likely to be male (male NT-SCI 52.5% vs T-SCI 71.6%, P=0.000) and had a shorter length of stay (median NT-SCI 21 days vs T-SCI 44 days, P=0.000). NT-SCI patients were also less disabled than T-SCI patients, having higher Functional Independence Measure motor subscale score on admission (median NT-SCI 53 vs T-SCI 38, P=0.000) and discharge (median NT-SCI 76 vs T-SCI 74, P=0.000). Previous demographic studies of NT-SCI and T-SCI patients are similar to our population-based results. More population-based research in SCI is required.

    This study is to investigate the effects of electroacupuncture at acupoints of the Governor Vessel(GV) on aquaporin-4 (AQP-4) expression and on functions of the hind limbs in the rat of spinal cord injury. The functions of the hind limbs were detected with BBB scale on the 1d, 3d, 7d and 21d after the spinal cord injury, respectively, and AQP-4 expression in the spinal cord was determined with immunohistochemical method and analyzed quantitatively with image analyzer. The results indicated that on the 1d after the spinal cord injury, increased AQP-4 expression can be seen significantly in both the gray matter and the white matter of the injured spinal cord, and it reached the peaks on the 3d after the spinal cord injury in both the electroacupuncture group and the spinal cord injury group. However, AQP-4 express was significantly decreased in the electroacupuncture group as compared with that in the control group on 7d, 14d and 21d (P<0.05 or P<0.01). The decrease of AQP-4 expression almost went with the improvement of the neurological function, which suggested that electroacupuncture at the acupoints of the Governor Vessel can inhibit edema of the spinal cord to alleviate the secondary spinal cord injury by means of decreasing the AQP-4 expression after the spinal cord injury, so as to protect the residual normal spinal cord tissues and promote the rebuilding of nervous tissues.

    Full Text Available Background: Traumatic spinal cord injury (SCI is major permanent sequelae of trauma with high burden and low frequency. In the setting of SCI is there any correlation between the timing of surgical decompression and sensory-motor improvement.Material and Methods: A literature review was performed using PUBMED from 1966 to 25th January 2010. Cross referencing of discovered articles was also reviewed.Results: The results of animal studies have shown that aside from the kind of procedure and species, when compression is less severe and of shorter duration, the neurological and histopathological recovery is significantly good. One meta-analysis, nine prospective studies, and one randomized clinical trial were identified. Conclusion: There are presently no standards regarding the role and timing of decompression in acute SCI. As a practice guideline, early surgery in less than 24 hours can be done safely in patients with acute SCI and urgent decompression is a reasonable practice option. Traction is the most practical method of achieving urgent decompression after cervical SCI. There are class III data to support a recommendation for urgent decompression in any patient with incomplete SCI with or without neurologic deterioration, with or without bilateral irreducible facet dislocations. There is emerging evidence that surgery within 24 hours may reduce both the length of intensive care unit stay and incidence of medical complications

    We describe a case of 55-years-old man with a known T11 AIS C since 1985. The muscle strength of his left leg is better than the right leg and he is an active community ambulator. He walks using his right knee ankle foot orthosis without a knee lock. However, on April 2012 he had undergone a left transtibial amputation secondary to infected diabetic foot ulcer. He only had his first contact with rehabilitation team 2 months after the amputation and started on gait retraining since. Given the fact that he is a K3 level as he used to climb Batu Caves which is known to have 272 steps and he plans to continue this activity for his religious purposes, we prescribed him with prosthesis - patella tendon bearing socket, pin and lock suspension, silicone liner and energy storing foot. In conclusion, a community ambulator in dual disabilities, that is, spinal cord injury and amputee is hardly encountered due to multiple confounding factors. However, the right prosthetic prescription in patient with good prognosticating factors to ambulate will determine successful rehabilitation.

    Endurance exercise training programs in patients with spinal cord injury (SCI) were largely studied to determine different types of adaptations. The aim of specific rehabilitation is to obtain maximal gains in quality-of-life (QoL) after SCI. To review the literature on the efficiency of training programs for SCI. We searched the MEDline database with the keywords SCI, paraplegia and quadriplegia and synonyms, then combined them with one of the following terms: rehabilitation, training, exercise conditioning, physical fitness, exercise prescription, adaptation, effect, or benefit. We found 65 articles related to the physiological and psychological effects of training programmes on patients with SCI. Training programs after SCI offer reconditioning cardiorespiratory, cardiovascular, cardiac, metabolic, bone, biomechanical, muscle adaptation, and QoL benefits. Reconditioning training increases VO2 max, reverses leg vascular resistance in the paralyzed legs and has possible cardiac and neural adaptations, favorable catecholamine responses and effects on platelet aggregation. Reconditioning can also modify lipid profile, reduce risk for cardiovascular diseases, prevent osteoporosis and increase maximal upper-extremity muscle strength, sprint power output and maximal power output. This effect allows for considerable improvement in mechanical efficiency and wheelchair propulsion technique. Reconditioning training programs after SCI have a direct impact on function and QoL, permitting participation in physical activities in addition to daily living activities in subjects with SCI.

    Barring unusual circumstances, sigmoid colostomy is the optimal technique for management of defecation in spinal cord injury (SCI) patients. We sought to provide evidence that a sigmoid colostomy is not difficult to perform in SCI patients and has better long-term results. The St. Louis Department of Veterans Affairs has a Commission on Accreditation of Rehabilitation Facilities (CARF)-approved SCI Unit. We reviewed the operative notes on all SCI patients who received a colostomy for fecal management by three ASCRS-certified colorectal surgeons at the St. Louis Department of Veterans Affairs from January 1, 2007 to November 26, 2012. There were 27 operations for which the recorded indication for surgery suggested that the primary disorder was SCI. Fourteen had traumatic SCI of the thoracic and/or lumbar spine and were evaluable. Of these 14 patients, 12 had laparoscopic sigmoid colostomy and two had open sigmoid colostomy. We encountered one evaluable patient with a remarkably large amount of retroperitoneal bony debris who successfully underwent laparoscopic sigmoid colostomy. In conclusion, sigmoid colostomy is the consensus optimal procedure for fecal management in SCI patients. Laparoscopic procedures are preferred. Care providers should specify sigmoid colostomy when contacting a surgeon.

    The management of chronic respiratory insufficiency and/or long-term inability to breathe independently has traditionally been via positive-pressure ventilation through a mechanical ventilator. Although life-sustaining, it is associated with limitations of function, lack of independence, decreased quality of life, sleep disturbance, and increased risk for infections. In addition, its mechanical and electronic complexity requires full understanding of the possible malfunctions by patients and caregivers. Ventilator-associated pneumonia, tracheal injury, and equipment malfunction account for common complications of prolonged ventilation, and respiratory infections are the most common cause of death in spinal cord-injured patients. The development of functional electric stimulation (FES) as an alternative to mechanical ventilation has been motivated by a goal to improve the quality of life of affected individuals. In this article, we will review the physiology, types, characteristics, risks and benefits, surgical techniques, and complications of the 2 commercially available FES strategies - phrenic nerve pacing (PNP) and diaphragm motor point pacing (DMPP).

    Neuromuscular electrical stimulation (NMES) over a muscle belly (mNMES) recruits superficial motor units (MUs) preferentially, whereas NMES over a nerve trunk (nNMES) recruits MUs evenly throughout the muscle. We performed tests to determine whether "interleaving" pulses between the mNMES and nNMES sites (iNMES) reduces the fatigability of contractions for people experiencing paralysis because of chronic spinal cord injury. Plantar flexion torque and soleus electromyography (M-waves) were recorded from 8 participants. A fatigue protocol (75 contractions; 2 s on/2 s off for 5 min) was delivered by iNMES. The results were compared with previously published data collected with mNMES and nNMES in the same 8 participants. Torque declined ∼40% more during mNMES than during nNMES or iNMES. M-waves declined during mNMES but not during nNMES or iNMES. To reduce fatigability of electrically evoked contractions of paralyzed plantar flexors, iNMES is equivalent to nNMES, and both are superior to mNMES.

    Spinal cord injury (SCI) is a devastating event that results in significant adjustments during the acute and rehabilitation phase. During this period, it is imperative to maintain the patient's self-esteem, reduce stress levels, encourage the expression of feelings, and provide sensory stimulation. Animal Assisted Therapy (AAT) involves the use of animals as a complement to more traditional forms of therapy. The program is based on the knowledge that animals have a positive influence on people who are ill in the healthcare setting. The Animals Heal Hearts Program (TM) has two components, pet visitation and pet therapy. Pet visitation consists of allowing a patient to have his/her own personal dog for a visit, provided there are no medical contraindications. Pet therapy is a structured program using a dog that has completed behavioral and health screening. Dogs are used in the hospital to reduce patients' stress, increase their self-esteem, and help them express feelings. The dogs provide sensory stimulation as patients view and handle the animals and learn about animals and pets. A carefully planned and evaluated program ensures that it is safe and effective.

    Full Text Available Spinal cord injury (SCI is a devastating disease which may cause physical, psychological and social dysfunction. Neuropathic pain (NP after SCI is common, can be seen in varying degrees and is one of the most difficultly treated problems developing after SCI. With the addition of the NP to loss of function after SCI, sleep patterns, moods and daily activities of patients are adversely affected. In order to treat pain effectively, classification of pain after SCI must be done carefully and correctly. According to classification of International Pain Study Group, pain after SCI is divided into two main groups as nociceptive and neuropathic pain. Neuropathic pain is defined as %u201Cpain occuring as a direct result of a disease or lesion directly affecting somato-sensorial system%u201D. NP after SCI can be classified according to anatomical region (above the level of lesion, at the level of lesion, below the level of lesion. Treatment of NP after SCI is often challenging and receiving response to treatment may take long time. Therefore, treatment of NP after SCI should be multifactorial. Treatment options include pharmochologic treatment, application of transcutanous electrical nerve stimulation, psychiatric treatment approaches, and surgical approaches in selected cases. In pharmachologic treatment, first line agents are tricyclic antidepresants, pregabalin and gabapentin. In this review, mechanisms and assessment and treatment of NP after SCI is discussed with the guide of current literature.

    Abnormal enhancement of polysynaptic brainstem reflexes has been previously reported in patients with spinal cord injury (SCI). We aimed to investigate trigemino-cervical reflex (TCR) in SCI since it may reflect alterations in the connections of trigeminal proprioceptive system and cervical motoneurons. Consecutive 14 patients with SCI and 16 healthy subjects were included in this study. All patients were in the chronic phase. TCR was recorded over sternocleidomastoid (SCM) and splenius capitis (SC) muscles by stimulation of infraorbital nerve. We measured onset latency, amplitudes and durations of responses and compared between groups. We obtained stable responses over both muscles after one sided stimulation in healthy volunteers whereas probability of TCR was decreased in patients over both SCM (78.6% vs. 100%, p=0.050) and SC (71.4% vs. 100%, p=0.022). The absence of TCR was related to use of oral baclofen (≥50mg/day). However, when present, responses of SCI group had higher amplitudes and were more persistent. We demonstrated that TCR probability was similar to healthy subjects in SCI patients who used no or low dose oral baclofen. But it had higher amplitudes and longer durations. It was not obtained in only two patients who used oral baclofen more than 50mg/day.

    It remains unclear whether spinal cord ischemia-reperfusion injury caused by ischemia and other non-mechanical factors can be monitored by somatosensory evoked potentials. Therefore, we monitored spinal cord ischemia-reperfusion injury in rabbits using somatosensory evoked potential detection technology. The results showed that the somatosensory evoked potential latency was significantly prolonged and the amplitude significantly reduced until it disappeared during the period of spinal cord ischemia. After reperfusion for 30-180 minutes, the amplitude and latency began to gradual y recover; at 360 minutes of reperfusion, the latency showed no significant difference compared with the pre-ischemic value, while the somatosensory evoked potential amplitude in-creased, and severe hindlimb motor dysfunctions were detected. Experimental findings suggest that changes in somatosensory evoked potential latency can reflect the degree of spinal cord ischemic injury, while the amplitude variations are indicators of the late spinal cord reperfusion injury, which provide evidence for the assessment of limb motor function and avoid iatrogenic spinal cord injury.

    Full Text Available Edaravone has been shown to delay neuronal apoptosis, thereby improving nerve function and the microenvironment after spinal cord injury. Edaravone can provide a favorable environment for the treatment of spinal cord injury using Schwann cell transplantation. This study used rat models of complete spinal cord transection at T 9. Six hours later, Schwann cells were transplanted in the head and tail ends of the injury site. Simultaneously, edaravone was injected through the caudal vein. Eight weeks later, the PKH-26-labeled Schwann cells had survived and migrated to the center of the spinal cord injury region in rats after combined treatment with edaravone and Schwann cells. Moreover, the number of PKH-26-labeled Schwann cells in the rat spinal cord was more than that in rats undergoing Schwann cell transplantation alone or rats without any treatment. Horseradish peroxidase retrograde tracing revealed that the number of horseradish peroxidase-positive nerve fibers was greater in rats treated with edaravone combined withSchwann cells than in rats with Schwann cell transplantation alone. The results demonstrated that lower extremity motor function and neurophysiological function were better in rats treated with edaravone and Schwann cells than in rats with Schwann cell transplantation only. These data confirmed that Schwann cell transplantation combined with edaravone injection promoted the regeneration of nerve fibers of rats with spinal cord injury and improved neurological function.

    Erythropoietin (EPO) is a promising therapeutic agent used in a variety of spinal cord injuries. Therefore, identifying the specific molecular pathway mediating the neuronal protective effect of EPO after spinal cord injury (SCI) is of great value to the patients concerned. Platelet-derived growth factor (PDGF)-B is an important factor in the recovery of neurological function. We explored changes in the expression of PDGF-B in spinal cord injury rats after receiving EPO treatment. We used a weight-drop contusion SCI model, and EPO treatment group rats received single doses of EPO (1,000 U/kg i.p.) immediately after the operation. Seven days after the operation, the results revealed a more rapid recovery as noted by the higher BBB scores, less disruption and more neuronal regeneration of the spinal cord in the EPO treatment group than that in the SCI group. PDGF-B expression also increased in the EPO treatment group compared to that in the SCI group (PEPO on spinal cord injury in rats, which may help to explain the quick recovery after EPO treatment of spinal cord injury.

    OBJECTIVE: Neural tissue transplantation has been a hot topic in medical researches on treatment of spinal cord injury. It provides a certain action on repair of peripheral neural injury in which schwann cell contained. But homo-transplantation of neural tissue is limited at the provider source and provider injury and hetero-transplantation of neural tissue exists immune inhibition and rejection. Microencapsulated technology is a kind of satisfactory immune isolation means. Whether microencapsulated hetero-transplantation of neural tissue reduces immunological rejection and deals with provider source is probed into so as to provide a new channel for clinical treatment of spinal cord injury.DATA SOURCES: By computer retrieval system, the relevant papers on the researches on spinal cord injury were looked up medline 1984 -01/2004 -10, limiting at the referred word "schwann cells, transplantation, xenogenic,spinal cord injury" in English. Simultaneously, the relevant papers were looked up by the computer on Zhongguo Linchuang Kangfu 2002-01/2004 - 10, focusing on the referred word "Schwann cells, transplantation,heterogenous, spinal cord injury" in Chinese; and the free words were limited at "microencapsulated" and "rat".DATA SELECTION: Totally 30 papers were selected on the original literatures on researches on repair of spinal cord injury at home and abroad. The original literatures on non-randomized researches were excluded and those on non-blind researches were not excluded.DATA EXTRACTION: Of 30 papers on repair of spinal cord injury, 22papers compiled with the standards, 8 papers on repair of spinal cord injury were excluded because of the repeated same research. The rest 22 papers on repair of spinal cord injury were classified for summarization.DATA SYNTHESIS: Axonal regenerative disturbance is the main factor to the persistent disablement resulting from spinal cord injury.

    Inflammation in general and proteinases generated as a result are likely mediators of early secondary pathogenesis after spinal cord injury. We report that matrix metalloproteinase-9 (MMP-9) plays an important role in blood-spinal cord barrier dysfunction, inflammation, and locomotor recovery. MMP-9 was present in the meninges and neurons of the uninjured cord. MMP-9 increased rapidly after a moderate contusion spinal cord injury, reaching a maximum at 24 hr, becoming markedly reduced by 72 hr, and not detectable at 7 d after injury. It was seen in glia, macrophages, neutrophils, and vascular elements in the injured spinal cord at 24 hr after injury. The natural tissue inhibitors of MMPs were unchanged over this time course. MMP-9-null mice exhibited significantly less disruption of the blood-spinal cord barrier, attenuation of neutrophil infiltration, and significant locomotor recovery compared with wild-type mice. Similar findings were observed in mice treated with a hydroxamic acid MMP inhibitor from 3 hr to 3 d after injury, compared with the vehicle controls. Moreover, the area of residual white matter at the lesion epicenter was significantly greater in the inhibitor-treated group. This study provides evidence that MMP-9 plays a key role in abnormal vascular permeability and inflammation within the first 3 d after spinal cord injury, and that blockade of MMPs during this critical period attenuates these vascular events and leads to improved locomotor recovery. Our findings suggest that early inhibition of MMPs may be an efficacious strategy for the spinal cord-injured patient.

Cellular therapy is an emerging area of research and has been found to possess many benefits in the previous studies. Transplantation of autologous bone marrow mononuclear cells (BMMNCs has demonstrated therapeutic potential for many neurological conditions, including spinal cord injury. Here we report a case of 6-year-old girl with traumatic SCI at the level of C7-D1 4 years back, who underwent 2 doses of cell transplantation with autologous BMMNCs with an interval of 6 months along with standard rehabilitation. The patient did not have any major or minor side effects. The patient showed clinical improvements throughout the 6 months after transplantation, which was assessed using Functional Independence Measure (before: 82, after: 101 out of 126. There were patchy areas of sensory gain in bilateral feet recorded, with improvements in the bladder sensation and control. Improved gait was seen as a result of better strength in abdominals and back extensors. The fact that there was functional improvement in the chronic plateau phase indicates the potential of cell therapy in chronic SCI. Further clinical studies are warranted.

    Experimental Study. The aim of this study was to investigate the neuroprotective effects of iloprost and piracetam on spinal cord ischemia/reperfusion (I/R) injury in the rabbit. The Experimental Research Center of Selcuk University, Konya, Turkey. A total of 24 rabbits were divided into four groups of six rabbits each, as follows: group 1 (n = 6) sham, laparotomy only; group 2 (n = 6) I/R; group 3 (n = 6) I/R+iloprost; and group 4 (n = 6) I/R+piracetam. I/R was established in groups 2, 3 and 4. Subsequently, they were followed up neurologically for 24 h until the rabbits were killed; biochemical and histopathological examinations of samples from the spinal cord were carried out. Neurological examination results were significantly better in the iloprost and piracetam groups compared with the I/R group (P iloprost and piracetam by suppressing malondialdehyde (P iloprost and piracetam groups were statistically different from the I/R group in terms of the number of apoptotic neurons in gray matter and white matter, as well as in terms of degenerated neurons and glial cells (P 0.05). This study has shown that iloprost and piracetam have neuroprotective effects in I/R injury both neurologically and histopathologically because of inhibition of lipid peroxidation.

    To address whether secretion removal techniques increase airway clearance in people with chronic spinal cord injury (SCI). MEDLINE/PubMed, CINAHL, EMBASE, and PsycINFO were searched from inception to May 2009 for population keywords (spinal cord injury, paraplegia, tetraplegia, quadriplegia) paired with secretion removal-related interventions and outcomes. Inclusion criteria for articles were a research study, irrespective of design, that examined secretion removal in people with chronic SCI published in English. Two reviewers determined whether articles met the inclusion criteria, abstracted information, and performed a quality assessment using PEDro or Downs and Black criteria. Studies were then given a level of evidence based on a modified Sackett scale. Of 2416 abstracts and titles retrieved, 24 met the inclusion criteria. Subjects were young (mean, 31 years) and 84% were male. Most evidence was level 4 or 5 and only 2 studies were randomized controlled trials. Three reports described outcomes for secretion removal techniques in addition to cough, whereas most articles examined the immediate effects of various components of cough. Studies examining insufflation combined with manual assisted cough provided the most consistent, high-level evidence. Compelling recent evidence supports the use of respiratory muscle training or electrical stimulation of the expiratory muscles to facilitate airway clearance in people with SCI. Evidence supporting the use of secretion removal techniques in SCI, while positive, is limited and mostly of low level. Treatments that increase respiratory muscle force show promise as effective airway clearance techniques.

    Neuropathic pain is common in patients with spinal cord injury (SCI) and often difficult to treat. We report a case where epidural spinal cord stimulation (SCS) below the level of injury has been successfully applied in a patient with a complete spinal cord lesion. A 53-year-old female presented with neuropathic below-level SCI pain of both lower legs and feet due to complete SCI below T5. Time and pain duration since injury was 2 years. Pain intensity was reported on numeric rating scale with an average of 7/10 (0 meaning no pain, 10 meaning the worst imaginable pain), but also with about 8-10 pain attacks during the day with an intensity of 9/10, which lasted between some minutes and half an hour. SCS was applied below the level of injury at-level T11-L1. After a successful 2 weeks testing period the pulse generator has been implanted permanently with a burst-stimulation pattern. The average pain was reduced to a bearable intensity of 4/10, in addition attacks could be reduced both in frequency and in intensity. This effects lasted for at least three months of follow-up. Even in case of complete SCI, SCS might be effective. Mechanisms of pain relief remain unclear. A modulation of suggested residual spinothalamic tract function may play a role. Further investigation has to be carried out to support this theory.

    Spinal cord injury (SCI) causes debilitating neurological dysfunction and has been observed in warfighters injured in IED blasts. Clinical benefit of SCI treatment remains elusive and better large animal models are needed to assess treatment options. Here, we describe a controlled electromagnetic spinal cord impactor for use in large animal models of SCI. A custom spinal cord impactor and platform were fabricated for large animals (e.g., pig, sheep, dog, etc.). Impacts were generated by a voice coil actuator; force and displacement were measured with a load cell and potentiometer respectively. Labview (National Instruments, Austin, TX) software was used to control the impact cycle and import force and displacement data. Software finite impulse response (FIR) filtering was employed for all input data. Silicon tubing was used a surrogate for spinal cord in order to test the device; repeated impacts were performed at 15, 25, and 40 Newtons. Repeated impacts demonstrated predictable results at each target force. The average duration of impact was 71.2 ±6.1ms. At a target force of 40N, the output force was 41.5 ±0.7N. With a target of 25N, the output force was 23.5 ±0.6N; a target of 15Newtons revealed an output force of 15.2 ±1.4N. The calculated acceleration range was 12.5-21.2m/s(2). This custom spinal cord impactor reliably delivers precise impacts to the spinal cord and will be utilized in future research to study acute traumatic SCI in a large animal.

    Full Text Available Aldehyde dehydrogenase 2 (ALDH2 is an important factor in inhibiting oxidative stress and has been shown to protect against renal ischemia/reperfusion injury. Therefore, we hypothesized that ALDH2 could reduce spinal cord ischemia/reperfusion injury. Spinal cord ischemia/reperfusion injury was induced in rats using the modified Zivin's method of clamping the abdominal aorta. After successful model establishment, the agonist group was administered a daily consumption of 2.5% alcohol. At 7 days post-surgery, the Basso, Beattie, and Bresnahan score significantly increased in the agonist group compared with the spinal cord ischemia/reperfusion injury group. ALDH2 expression also significantly increased and the number of apoptotic cells significantly decreased in the agonist group than in the spinal cord ischemia/reperfusion injury group. Correlation analysis revealed that ALDH2 expression negatively correlated with the percentage of TUNEL-positive cells (r = −0.485, P < 0.01. In summary, increased ALDH2 expression protected the rat spinal cord against ischemia/reperfusion injury by inhibiting apoptosis.

    Lack of axon regeneration following spinal cord injury has been mainly ascribed to the inhibitory environment of the injury site, i.e., to chondroitin sulfate proteoglycans (CSPGs) and myelin-associated inhibitors (MAIs). Here, we used shiverer (shi) mice to assess axon regeneration following spinal cord injury in the presence of MAIs and CSPG but in the absence of compact myelin. Although in vitro shi neurons displayed a similar intrinsic neurite outgrowth to wild-type neurons, in vivo, shi fibers had increased regenerative capacity, suggesting that the wild-type spinal cord contains additional inhibitors besides MAIs and CSPG. Our data show that besides myelin protein, myelin lipids are highly inhibitory for neurite outgrowth and suggest that this inhibitory effect is released in the shi spinal cord given its decreased lipid content. Specifically, we identified cholesterol and sphingomyelin as novel myelin-associated inhibitors that operate through a Rho-dependent mechanism and have inhibitory activity in multiple neuron types. We further demonstrated the inhibitory action of myelin lipids in vivo, by showing that delivery of 2-hydroxypropyl-β-cyclodextrin, a drug that reduces the levels of lipids specifically in the injury site, leads to increased axon regeneration of wild-type (WT) dorsal column axons following spinal cord injury. In summary, our work shows that myelin lipids are important modulators of axon regeneration that should be considered together with protein MAIs as critical targets in strategies aiming at improving axonal growth following injury.

    Full Text Available Abstract Background Glutamergic excitotoxicity has been shown to play a deleterious role in the pathophysiology of spinal cord injury (SCI. The aim of this study was to investigate the neuroprotective effect of dizocilpine maleate, MK801 (2 mg/Kg, 30 min and 6 hours after injury in a mice model of SCI. The spinal cord trauma was induced by the application of vascular clips to the dura via a four-level T5-T8 laminectomy. Results Spinal cord injury in mice resulted in severe trauma characterized by edema, neutrophil infiltration and apoptosis. In this study we clearly demonstrated that administration of MK801 attenuated all inflammatory parameters. In fact 24 hours after injury, the degree of spinal cord inflammation and tissue injury (evaluated as histological score, infiltration of neutrophils, NF-κB activation, iNOS, cytokines levels (TNF-α and IL-1β, neurotrophin expression were markedly reduced by MK801 treatment. Moreover, in a separate set of experiments, we have demonstrated that MK801 treatment significantly improved the recovery of locomotory function. Conclusions Blockade of NMDA by MK801 lends support to the potential importance of NMDA antagonists as therapeutic agents in the treatment of acute spinal cord injury.

    Full Text Available Deferoxamine, a clinically safe drug used for treating iron overload, also repairs spinal cord injury although the mechanism for this action remains unknown. Here, we determined whether deferoxamine was therapeutic in a rat model of spinal cord injury and explored potential mechanisms for this effect. Spinal cord injury was induced by impacting the spinal cord at the thoracic T10 vertebra level. One group of injured rats received deferoxamine, a second injured group received saline, and a third group was sham operated. Both 2 days and 2 weeks after spinal cord injury, total iron ion levels and protein expression levels of the proinflammatory cytokines tumor necrosis factor-α and interleukin-1β and the pro-apoptotic protein caspase-3 in the spinal cords of the injured deferoxamine-treated rats were significantly lower than those in the injured saline-treated group. The percentage of the area positive for glial fibrillary acidic protein immunoreactivity and the number of terminal deoxynucleotidyl transferase dUTP nick end labeling-positive cells were also significantly decreased both 2 days and 2 weeks post injury, while the number of NeuN-positive cells and the percentage of the area positive for the oligodendrocyte marker CNPase were increased in the injured deferoxamine-treated rats. At 14–56 days post injury, hind limb motor function in the deferoxamine-treated rats was superior to that in the saline-treated rats. These results suggest that deferoxamine decreases total iron ion, tumor necrosis factor-α, interleukin-1β, and caspase-3 expression levels after spinal cord injury and inhibits apoptosis and glial scar formation to promote motor function recovery.

    A rat model of spinal cord injury was established using the weight drop method. A cavity formed 14 days following spinal cord injury, and compact scar tissue formed by 56 days. Enzyme-linked immunosorbent assay and polymerase chain reaction enzyme-linked immunosorbent assay results demonstrated that glial fibrillary acidic protein and telomerase expression increased gradually after injury, peaked at 28 days, and then gradually decreased. Spearman rank correlation showed a positive correlation between glial fibrillary acidic protein expression and telomerase expression in the glial scar. These results suggest that telomerase promotes glial scar formation.

    Lower vertebrates, such as fish and amphibians, and higher vertebrates in embryonic development can acquire complete regeneration of complex body structures, including the spinal cord, an important part of the central nervous system. However, with species evolution and development, this regenerative capacity gradually weakens and even disappears, but the cellular and molecular mechanisms remain poorly understood. We explored the differences in mechanisms of spinal cord regeneration capability between lower and higher vertebrates, investigated differences in their cellular and molecular mechanisms and between the spinal cord structures of lower vertebrates and mammals, such as rat and monkey, to search for theoretical evidence and therapeutic targets for nerve regeneration in human spinal cord.

    Full Text Available A 24-year-old male was transferred to the emergency department while being in the state of quadriplegia with a history of performing Parkour sport, which is also called double front flip. Neurological examination revealed that the patient’s muscle power was 0/5 at all extremities. The patient did not show any sense of light touch or pain in his extremities. In radiological studies, cervical spine X-ray and CT scan images showed C4-C5 subluxation with bilateral locked facets and spinal cord injury. The results of this very rare case study revealed that exercising Parkour sport without taking into account safety standards could result in irreversible injuries to the cervical spinal cord with fatal outcome.

    A 17-year-old male soccer player presented with numbness in the upper- and lower-left extremities of 6 months' duration. He had no apparent history of trauma but experienced neck pain during heading of the ball 5 years prior. A high-signal intensity area was seen on T2-weighted magnetic resonance imaging (MRI) of the cervical spine. No muscle weakness was observed. Hypoesthesia was observed in bilateral forearms, hands, and extremities below the inguinal region. Plain radiographs in the neutral position showed local kyphosis at C3/4. A small protrusion of the C3/4 disk was observed on T1-weighted MRI. A high-signal area in the spinal cord at the C3/4 level was observed on T2-weighted MRI, but this was not enhanced by gadolinium. Multiple sclerosis, intramedullary spinal cord tumor, sarcoidosis and malignant lymphoma, and spinal cord injury were all considered in the differential diagnosis. However, in view of the clinical, laboratory, and radiological investigations, we concluded that repeated impacts to the neck caused by heading of the ball during soccer induced a chronic, minor spinal cord injury. This contributed to the high-signal intensity change of the spinal cord in T2-weighted MRI. The present case demonstrates that repeated impact may cause chronic spinal cord injury. Soccer, American football, or rugby players presenting with neck or extremity symptoms should not be overlooked for the possibility of latent spinal cord injury, as this could present later development of more severe or unrecoverable spinal cord injuries.

    Inpatient rehabilitation for spinal cord injury (SCI) includes the use of both individual and group physical therapy sessions. A greater understanding of group physical therapy use will help in the evaluation of the appropriateness of its use and contribute to the development of standards of practice. This report describes the extent to which group physical therapy is being used in inpatient rehabilitation for SCI, identifies group physical therapy interventions being delivered, and examines patterns in the types of activities being used for people with different levels and completeness of injury (ie, injury groups). The SCIRehab Study is a 5-year, multicenter investigation that uses practice-based evidence research methodology. Data on characteristics of participants and treatments provided were collected through detailed chart review and customized research documentation completed by clinicians at the point of care. The analyses described here included data from 600 participants enrolled during the first year of the project. Most of the participants (549/600) spent time in group physical therapy, and 23% of all documented physical therapy time was spent in group sessions. The most common group physical therapy activities were strengthening, manual wheelchair mobility, gait training, endurance activities, and range of motion/stretching. Time spent in group physical therapy and the nature of activities performed varied among the injury groups. Physical therapy use patterns observed in the 6 participating centers may not represent all facilities providing inpatient rehabilitation for SCI. Research documentation did not include all factors that may affect group physical therapy use, and some sessions were not documented. The majority of physical therapy was provided in individual sessions, but group physical therapy contributed significantly to total physical therapy time. Group physical therapy time and activities differed among the injury groups in patterns

    No research using standardized tests based on direct observations along with longitudinal studies have shown the effects of service dogs on persons with mobility impairment. Our research objectives were to document the consequences of the use of the service dog on wheelchair propelling, grasping objects, shoulder pain, occupational performance, reintegration into normal living and psychosocial impacts for people with spinal cord injury (SCI). A cross sectional study was conducted with 45 males and 21 females with SCI (average age = 41.2). They were assessed in their homes and their communities, two to five years after they received their service dogs. Observations were based on four testing methods. An ongoing longitudinal study is reported, based on 9 months (n = 8 to 16) of data from four standardised questionnaires. Results demonstrate that services dogs are an efficient assistive technology for persons with SCI.

    Individuals who experience loss of their physical abilities often face the challenges of adapting to a new way of life. Past research has shown that sport participation can assist the physical and psychological adaptation to acquired physical disabilities. The purposes of our study were to examine the following: (a) the resilience process of sport participants with acquired spinal cord injury, and (b) the role of sport participation in the resilience process. We conducted semistructured phenomenological interviews with 12 male quadriplegic wheelchair rugby players. Results show that the development of resilience is a multifactorial process involving pre-existing factors and pre-adversity experiences, disturbance/disturbing emotions, various types and sources of social support, special opportunities and experiences, various behavioral and cognitive coping strategies, motivation to adapt to changes, and learned attributes or gains from the resilience process. We discuss implications for future research and practice.

    Acute traumatic spinal cord injury results in disability and use of health care resources, yet data on contemporary national trends of traumatic spinal cord injury incidence and etiology are limited. To assess trends in acute traumatic spinal cord injury incidence, etiology, mortality, and associated surgical procedures in the United States from 1993 to 2012. Analysis of survey data from the US Nationwide Inpatient Sample databases for 1993-2012, including a total of 63,109 patients with acute traumatic spinal cord injury. Age- and sex-stratified incidence of acute traumatic spinal cord injury; trends in etiology and in-hospital mortality of acute traumatic spinal cord injury. In 1993, the estimated incidence of acute spinal cord injury was 53 cases (95% CI, 52-54 cases) per 1 million persons based on 2659 actual cases. In 2012, the estimated incidence was 54 cases (95% CI, 53-55 cases) per 1 million population based on 3393 cases (average annual percentage change, 0.2%; 95% CI, -0.5% to 0.9%). Incidence rates among the younger male population declined from 1993 to 2012: for age 16 to 24 years, from 144 cases/million (2405 cases) to 87 cases/million (1770 cases) (average annual percentage change, -2.5%; 95% CI, -3.3% to -1.8%); for age 25 to 44 years, from 96 cases/million (3959 cases) to 71 cases/million persons (2930 cases), (average annual percentage change, -1.2%; 95% CI, -2.1% to -0.3%). A high rate of increase was observed in men aged 65 to 74 years (from 84 cases/million in 1993 [695 cases] to 131 cases/million [1465 cases]; average annual percentage change, 2.7%; 95% CI, 2.0%-3.5%). The percentage of spinal cord injury associated with falls increased significantly from 28% (95% CI, 26%-30%) in 1997-2000 to 66% (95% CI, 64%-68%) in 2010-2012 in those aged 65 years or older (P spinal cord injury remained relatively stable but, reflecting an increasing population, the total number of cases increased.

    Schwann cells are glial cells of peripheral nervous system, responsible for axonal myelination and ensheathing, as well as tissue repair following a peripheral nervous system injury. They are one of several cell types that are widely studied and most commonly used for cell transplantation to treat spinal cord injury, due to their intrinsic characteristics including the ability to secrete a variety of neurotrophic factors. This mini review summarizes the recent findings of endogenous Schwann cells after spinal cord injury and discusses their role in tissue repair and axonal regeneration. After spinal cord injury, numerous endogenous Schwann cells migrate into the lesion site from the nerve roots, involving in the construction of newly formed repaired tissue and axonal myelination. These invading Schwann cells also can move a long distance away from the injury site both rostrally and caudally. In addition, Schwann cells can be induced to migrate by minimal insults (such as scar ablation) within the spinal cord and integrate with astrocytes under certain circumstances. More importantly, the host Schwann cells can be induced to migrate into spinal cord by transplantation of different cell types, such as exogenous Schwann cells, olfactory ensheathing cells, and bone marrow-derived stromal stem cells. Migration of endogenous Schwann cells following spinal cord injury is a common natural phenomenon found both in animal and human, and the myelination by Schwann cells has been examined effective in signal conduction electrophysiologically. Therefore, if the inherent properties of endogenous Schwann cells could be developed and utilized, it would offer a new avenue for the restoration of injured spinal cord.

    Full Text Available David R Dolbow School of Kinesiology, University of Southern Mississippi, Hattiesburg, MS, USA Abstract: Spinal cord injuries (SCIs can have catastrophic effects on individuals resulting in loss of physical abilities and independence. Loss of the ability to perform activities of daily living reduces the quality of life. Furthermore, decreased ability to perform physical activities decreases overall fitness and increases the risk of diseases related to sedentary lifestyle. Activity-based restorative therapies (ABRTs provide an option to help optimize rehabilitation through the restoration of function and the introduction to physical activities via adapted equipment. ABRT programs are typically located in SCI centers, which limit long-term access to those not living near the facilities. Typical rehabilitation clinics not specializing in SCI care are able to provide modified ABRT programs, but lack the staffing and adaptive equipment provided in the larger SCI rehabilitation centers. For long-term rehabilitation and wellness needs, the placement of adaptive equipment in the homes of those with SCI has proven to be beneficial, although costly as highly technical equipment such as functional electrical stimulation cycles usually cost over US$20,000. Community fitness centers offer some possible options for long-term exercise through inclusive fitness programs but many still lack full accessibility for those who are wheelchair reliant and most do not provide specialized adaptive equipment or trained staff to meet the special needs of individuals with SCI and other paralytic conditions. It is important for health care providers to continue to advocate for useful and less expensive adaptive equipment that may provide exercise to paralyzed muscles and greater access and accommodation of wheelchair-reliant individuals by community fitness centers.

    Retrospective economic analysis. To determine the total direct costs of publicly funded health care utilization for the three fiscal years 2003/04 to 2005/06 (1 April 2003 to 31 March 2004 to 1 April 2005 to 31 March 2006), from the time of initial hospitalization to 1 year after initial acute discharge among individuals with traumatic spinal cord injury (SCI). Ontario, Canada. Health system costs were calculated for 559 individuals with traumatic SCI (C1-T12 AIS A-D) for acute inpatient, emergency department, inpatient rehabilitation (that is, short-stay inpatient rehabilitation), complex continuing care (CCC) (i.e., long-stay inpatient rehabilitation), home care services, and physician visits in the year after index hospitalization. All care costs were calculated from the government payer's perspective, the Ontario Ministry of Health and Long-Term Care. Total direct costs of health care utilization in this traumatic SCI population (including the acute care costs of the index event and inpatient readmission in the following year after the index discharge) were substantial: $102 900 per person in 2003/04, $100 476 in 2004/05 and $123 674 in 2005/06 Canadian Dollars (2005 CDN $). The largest cost driver to the health care system was inpatient rehabilitation care. From 2003/04 to 2005/06, the average per person cost of rehabilitation was approximately three times the average per person costs of inpatient acute care. The high costs and long length of stay in inpatient rehabilitation are important system cost drivers, emphasizing the need to evaluate treatment efficacy and subsequent health outcomes in the inpatient rehabilitation setting.

    Full Text Available Purpose: To identify factors influencing the sexual health of women with spinal cord injury (SCI in Bangladesh.Methods: This study used both qualitative and quantitative methods. The quantitative part used a case-control design. Cases were women with SCI and controls were age-matched women without SCI.  Questionnaires were used to collect data concerning the sexual health status of women. Multivariate logistic regression was done to determine which factors had an independent effect on sexual health.  In-depth interviews were held with a sub-group of women from both groups, and interview guides were used. The in-depth interview data was subjected to content analysis.Results: In total, 92 questionnaires were given out and 30 in-depth interviews were conducted. A relationship was found between physical factors and sexual health, as pain, vaginal dryness and physical discomfort were mentioned more frequently among women with SCI. Environmental and emotional factors such as stigma, satisfaction of the husband and support from the husband and friends had an influence on the sexual health of the women with SCI, as well as the other group of women.Conclusions: From interviews it became clear that most of the women with SCI were dissatisfied with their sexual health as compared to the women without SCI. However, environmental and emotional factors such as attitudes, support and stigma, rather than physical factors, were the most important influences on sexual health in both groups of women.doi: 10.5463/dcid.v23i3.60

    Prospective cohort study. To determine incidence of contracture and develop prediction models to identify patients susceptible to contracture after spinal cord injury. Two Sydney spinal cord injury units. A total of 92 consecutive patients with acute spinal cord injury were assessed within 35 days of injury and 1 year later. Incidence of contracture at 1 year was measured in all major appendicular joints by categorizing range of motion on a 4-point scale (0-no contracture to 3-severe contracture), and in the wrist, elbow, hip and ankle by measuring range of motion at standardized torque. Multivariate models were developed to predict contracture at 1 year using age, neurological status, spasticity, pain and limb fracture recorded at the time of injury. At 1 year, 66% of participants developed at least one contracture (defined as ≥1 point deterioration on the 4-point scale). Incidence of contracture at each joint was: shoulder 43%, elbow and forearm 33%, wrist and hand 41%, hip 32%, knee 11% and ankle 40%. Incidence of contracture determined by standardized torque measures of range (defined as loss of ≥10 degrees) was: elbow 27%, wrist 26%, hip 23% and ankle 25%. Prediction models were statistically significant but lacked sufficient predictive accuracy to be clinically useful (R(2)≤31%). The incidence of contracture in major joints 1 year after spinal cord injury ranges from 11-43%. The ankle, wrist and shoulder are most commonly affected. It is difficult to accurately predict those susceptible to contracture soon after injury.

    Objective To explore repair of spinal cord injury by neural stem cells (NSCs) modified with brain derived neurotrophic factor (BDNF) gene (BDNF-NSCs) in rats. Methods Neural stem cells modified with BDNF gene were transplanted into the complete transection site of spinal cord at the lumbar 4 (L4) level in rats. Motor function of rats'hind limbs was observed and HE and X-gal immunocytochemical staining, in situ hybridization, and retrograde HRP tracing were also performed. Results BDNF-NSCs survived and integrated well with host spinal cord. In the transplant group, some X-gal positive, NF-200 positive, GFAP positive, BDNF positive, and BDNF mRNA positive cells, and many NF-200 positive nerve fibers were observed in the injury site. Retrograde HRP tracing through sciatic nerve showed some HRP positive cells and nerve fibers near the rostral side of the injury one month after transplant and with time, they increased in number. Examinations on rats' motor function and behavior demonstrated that motor function of rats' hind limbs improved better in the transplant group than the injury group. Conclusion BDNF-NSCs can survive, differentiate,and partially integrate with host spinal cord, and they significantly ameliorate rats ' motor function of hind limbs, indicating their promising role in repairing spinal cord injury.

    Full Text Available Objectives: The role of injury-related variables in determining health-related quality of life (HRQOL among Iranian persons with spinal cord injury (SCI has not yet been fully described. In this study, we compared HRQOL between individuals with injury at cervical level and those with injury at thoracolumbar sections and evaluated the discriminating value of injury level as a determinant of HRQOL among Iranian people with SCI. Methods: Individuals with SCI, who were referred to Brain and Spinal Cord Injury Research Center, were invited to participate in this investigation. HRQOL was assessed using the Short Form (SF-36 questionnaire to determine the quality of life (QOL in eight domains: physical functioning (PF, role limitation due to physical problems (RP, bodily pain (BP, general health (GH, vitality (VT, social functioning (SF, role limitation due to emotional problems (RE, and mental health (MH. Results: Ninety patients with paraplegia and 94 quadriplegic patients participated in this investigation. The mean score of PF domain was significantly lower in patients with injury at cervical level (p < 0.0001. There was no significant difference in other domains of SF-36 between subjects with paraplegia and quadriplegia (p = 0.670, 0.700, 0.910, 0.710, 0.730, 0.290 and 0.850 for RP, RE, VT, MH, SF, BP and GH, respectively. Similarly, the mean physical component summary (PCS score was significantly higher among individuals with injury at thoracolumbar sections (p < 0.0001. The mean mental component summary (MCS score did not differ between the two groups (p = 0.720. Conclusions: Patients with SCI at the cervical level have similar mental health compared to those with injury at thoracolumbar sections, which shows proper mental adaptability in quadriplegic individuals. Injury level can be used as a major determinant of the physical component of QOL among people with SCI.
