Filter by:The annual incidence of traumatic spinal cord injury (SCI) is estimated at 2,500 (35 per week) in the UK and, due to advances in research and clinical management, the majority now have incomplete injuries, with significant potential for neurological improvement. Discovering ways to provide intensive, but cost-effective SCI rehabilitation is therefore increasingly important. The iCycle combines functional electrical stimulation (FES) cycling with VR cycle-racing feedback, where winning correlates with voluntary effort, to promote recovery. The aim is to improve walking in people with incomplete injuries, fundamental to independence and quality of life as well as long-term health. More intensive rehabilitative training is associated with better outcomes: the iCycle has the potential to increase intensity of exercise without additional demands on therapists' time and therefore cost. Following the encouraging results in an initial study; it is now important to find out whether recovery will continue at a similar rate if iCycle training continues beyond 4 weeks. Six volunteers with SCI will be recruited to participate in this 20 week, single-site open feasibility trial. The trial consists of an intervention phase lasting up to 12 weeks (3 iCycle sessions per week), and an 8-week follow-up phase. Outcome measures (ISNC-SCI motor scoring, Trunk Impairment scale, Walking Index for Spinal Cord Injury, 6-minute walk test, Goal Attainment Scale and TMS) will be taken every 4 weeks. The 12-week intervention phase will be separated into three 4-week blocks; at the end of each block participants may decide whether or not they wish to continue training.
The purpose of this feasibility study is to compare the impact of Spinal cord stimulation [SCS] for Spinal Cord Injury (SCI) pain and rehabilitation. SCS, also known as Epidural Electrical Stimulation (EES), will be utilized along with conventional medical management (CMM) or CMM alone. Participation in this research study is expected to last approximately 12 months. All subjects will be evaluated and proceed with implantation of two SCS devices- one tailored based on the individual's SCI for the treatment of neuropathic pain of trunk and limb and a second near the bottom of the spinal cord (conus region) to study the impact on motor, sensory, bowel/bladder outcomes. All patients will also continue receiving CMM, such as medications and physical therapy. Participating subjects will be randomly assigned to one of two treatment groups: 1. Placebo arm: SCS OFF + CMM. Under the direction of the study physician, the patient may receive a variety of treatments, such as medications and various forms of rehabilitation. 2. Treatment arm: SCS ON + CMM. The study treatment Spinal Cord Stimulation [SCS]: the study physician will perform a trial procedure to see if the study procedure works for the patient and may implant a permanent device if it is successful. There is a temporary trial procedure, or a "test drive," which usually lasts 5-7 days. If this is successful, patients will discuss a more permanent implant. This study involves the concurrent placement of two SCS devices (one focused on pain and the second for rehabilitation). For three months, treatment group subjects will have the SCS turned on and will have rehabilitation as part of their CMM. Participants in the placebo arm will have their SCS remain off and will undergo CMM with rehabilitation therapy similar to the treatment group. Neither the subjects nor the treatment team will know which patients are in the treatment or placebo arm. At the end of three months, the study group will be revealed and the placebo group subjects will be allowed to crossover and have their SCS turned on. Rehabilitation visits may be remote and the study duration is approximately 12 months. There may be additional blood tests and clinical exams to collect data on the effectiveness of the therapy. Data at follow-up visits will be compared to the subjects' baseline data and that of the control group at the respective visits.
Spinal cord injuries (SCI) are among the most debilitating conditions an individual can sustain with the estimates of SCI incidence in the United States at 12,000 new cases per year. The loss of innervation to the tissues muscle below the level of the lesion results in reduced physical activity which leads to an array of secondary complications including muscle atrophy, cardiovascular and metabolic disease, obesity and vascular dysfunction. This further leads to exercise intolerance, reduced quality of life and depression. Although current rehabilitative programs focus on improving muscle strength in this population, the efficacy of these programs is challenged by the injury related motor impairment, which limits the exercise intensity and subsequent positive muscular adaptations. Therefore, development of an exercise program that promotes maximal muscular adaptations to light intensity exercise could greatly improve the efficacy of rehabilitation in the SCI population and help restore functional capacity and quality of life for these individuals. Blood flow restriction (BFR) exercise has shown tremendous promise for improving muscle size and strength in a variety of healthy and clinical populations, however the benefits of BFR exercise for those with SCI has not been established. Thus, the purpose of this Merit proposal is to conduct a comprehensive study that explores the benefits and risks of BFR exercise in the incomplete SCI population. In general individuals with chronic incomplete SCI will be recruited to partake in two 8-week training periods (20 sessions) that involve traditional knee extension/flexion exercise or knee extension/flexion exercise with blood flow restriction. There will be a series of measurements before and after the 8-week intervention to look at changes in muscle and vascular function. Specific Aim 1 will determine how the 8-weeks of BFR exercise influenced muscle strength (Biodex isokinetic dynamometer), muscle cross sectional area and volume (CTscan) and fatigue resistance. Specific Aim 2 will determine how this novel 8-week training intervention impacts peripheral vascular function. Specifically, changes in nitric oxide mediated endothelial function will be determined through tests of flow mediated dilation, changes in endothelial function of the microvascular network will be determined through assessments of reactive hyperemia and changes in arterial stiffness will be determined through measurements of pulse wave velocity. Specific Aim 3 will focus on the safety of BFR exercise for the SCI population. Those with SCI are at greater risk for thrombosis and DVT compared to able bodied individuals. Although unlikely, the introduction of temporary blood stasis during BFR exercise might augment this risk. Thus, the third aim of this study will be to determine changes in innate immune activation and thrombosis risk. Specifically, blood will be collected at multiple timepoints throughout the training intervention and analyzed for hypoxia-inducible factor 1-alpha, neutrophil extra cellular traps (which act as prothrombotic scaffolds), neutrophil-platelet aggregates and inflammatory cytokines. Ultimately, if the improvements in muscle and vascular function following BFR resistance exercise is greater than the traditional resistance exercise often performed in rehabilitation settings, without increasing risk for DVT, it should be incorporated into the long-term rehabilitation programs for Veterans with SCI.
Objectives: The study objective is to carry a pilot clinical assessment comparing the exciflex bandage to standard of care (SoC) for ischemic wounds and will involve participants who are Veterans with lower extremity ischemic wounds. Research Plan: The study will employ a randomized repeated measures design to assess the therapeutic effectiveness of exciflex in clinical use. Methodology: All participants with chronic ischemic wounds treated at LSCDVAMC will be potentially eligible for the study. Primary target populations will include Veterans with SCI who are inpatients or residents of the on-site Long Term Care Unit and Veterans with diabetes being followed by the Podiatry Service for wound care. In addition to meeting the general inclusion criteria noted above, further exclusion criteria relating to clinical factors include; (1)Age less than 18 years and (2)Pregnancy. Clinical Significance: Chronic ischemic wounds fail to heal normally and are a major challenge in the long-term care of many Veterans. The exciflex bandage can improve outcomes and lower cost by automatically delivering electrotherapy without disturbing the wound dressing for up to seven days, unless indicated. The overall study goal is to complete pre-market testing and evaluation of the exciflex bandage system.
This is a phase 1 study of safety and feasibility of cervical spinal cord stimulator implantation in cervical SCI subjects who are ventilator dependent. The Investigators will be focusing on the safety and feasibility of this approach. Participants may qualify for the study if they are male or female 18-75 years old, are at least 1 year after original injury, have injury at C2 to C7 level, and dependent on mechanical ventilation to help them breathe. Additionally, they need to be able to attend up to twice weekly testing sessions for up to 21 months.
The loss of movement and walking ability significantly affects quality of life after spinal cord injury. In addition, bladder dysfunction consistently ranks as one of the top disorders affecting quality of life after spinal cord injury. The overall objective of this study is to demonstrate that epidural stimulation may be a method for improving stepping, standing and bladder function in individuals with spinal cord injury. With the use of epidural stimulation, the investigators propose to investigate how well the participant can stand and walk and how well the participant's bladder can store or hold urine as well as void or empty urine. The results of this study may aid in the development of treatments to help individuals with spinal cord injuries that are unable to stand or walk and have impaired bladder function.
Respiratory failure and dyspnea are common in spinal cord injury (SCI), and in acute situations, any spinal cord lesion above T11 can cause abnormal respiratory function and impair the airway clearance. Although surgical decompression is one of the key early neuroprotective therapies, surgery and general anesthesia disrupt many aspects of respiratory function and may cause a series of postoperative pulmonary complications. Endotracheal suction is important to reduce the risk of lung consolidation and atelectasis. But for patients with respiratory insufficiency such as SCI, ordinary suction is not enough to clear secretions in the deeper airways. And repeated intratracheal suction may even cause some serious complications. Bronchoscopy can generally penetrate into the bronchus of grade 3-4, and fully attract the secretions in it under visual conditions. Its curative effect on pneumonia and atelectasis in the ICU has been affirmed, but no one has yet explored the application in the postoperative care unit .
The purpose of this research project is to investigate the incidence of impaired swallowing (dysphagia) after anterior cervical spine surgery (ACSS) and to study the long-term effect of dysphagia on nutritional status 12 ± 3 months later. Furthermore, to investigate the effect of a new rehabilitation method for dysphagia among individuals with swallowing dysfunction after ACSS.
After incomplete spinal cord injury (iSCI), many people still have control over their upper and/or lower limbs, but secondary conditions such as spasticity impair the function they have left. Spasticity includes increased reflex response and muscle tone, and is often painful. In this study we want to test a rehabilitation therapy to reduce spasticity after iSCI and improve participants' control over their extremities. The study involves recording participants' brain signals (EEG) and displaying them on a computer, so that they learn to control specific features derived from their brain waves. This is called neurofeedback (NF). Two studies conducted in our group that explored NF effect on central neuropathic pain in iSCI reported as incidental finding a decrease in spasms, muscle tightness and foot drop. The effect of NF is immediate and lasts up to 24 hours. In this study, we will explore systematically the short- and medium-term effect of NF on a larger number of iSCI, to inform a potential randomized clinical trial. Gaining control over one's brain activity requires practice and 80-90% people eventually learn the skill. Each participant will therefore attend five sessions of NF taking no longer than two hours each. 20 participants will be recruited and assigned to either upper or lower limb spasticity groups. This will allow us to determine if the mechanism of NF differs between arms and legs. Participants will be further grouped into sub-acute and chronic groups, depending on the time since injury, to pinpoint at what stage post-injury NF is the most effective. All groups will receive the same number of NF sessions. The primary outcome of this study is the change in spasticity of the hand or leg, as measured by the Modified Ashworth Scale (MAS). Secondary outcomes include use of arm/leg, quality of life, and the relation between functional improvement and EEG changes. Outcomes will be compared before/after each session, and before/after the whole intervention period, both inter- and intra-group.
The reason for conducting this study is to learn about the best ways to help Veterans with spinal cord injury (SCI) gain meaningful employment. Spinal cord injury is a medically complex disability that poses unique barriers to employment for Veterans. Returning to work after SCI improves health and quality of life, which in turn can lower risk for suicide in this high-risk population. Hence, the Department of Veterans Affairs (VA) supports interventions that help Veterans with SCI return to work and may prevent suicide. Customized employment (CE) is an innovative strategy for tailoring vocational services to meet the needs of people with complex disabilities. To address barriers to employment faced by Veterans with SCI, this study will evaluate whether a customized employment intervention used in non-VA settings can be adapted for use by the VA as a part of SCI medical rehabilitation. The research goal is to evaluate how a CE intervention for Veterans with SCI (ACCESS-Vets) can help them discover their strengths to find and maintain competitive integrated employment in their communities. This study will compare ACCESS-Vets with the usual evidence-based supported employment program, known as Individual Placement and Support (IPS). Veterans with SCI who chose to participate in this study will be randomly selected (i.e. by chance) to work with a vocational rehabilitation specialist as part of the ACCESS-Vets intervention or the usual IPS employment program for about 8 months. Study participants will complete study questionnaires before, during, and after their participation in the employment interventions. Some Veterans and their medical rehabilitation providers will be interviewed about their experiences with the employment interventions. The study expects to find that Veterans who participate in ACCESS-Vets will have better employment and quality of life outcomes then those who participate in IPS. The study will provide information about the strategies used in the ACCESS-Vets and IPS interventions for addressing barriers to employment. Ultimately, this study may provide a model for making VA vocational services for Veterans with SCI more effective and sustainable.
