Active clinical trials for "Spinal Cord Injuries"

Aim is to compare exoskeleton assisted gait training with end-effector assisted gait training in Spinal Cord Rehabilitation

Background: In Switzerland, about 6000 individuals live with the consequences of a spinal cord injury (Brinkhof et al, 2016). One of the major goals after an incomplete spinal cord injury (iSCI) is to regain walking function. To this end, different approaches are used in rehabilitation such as treadmill-based, robotic-assisted (exoskeleton or end-effector) and conventional gait training. According to current literature, the superiority of one of these approaches remains unclear (Mehrholz, Harvey, Thomas, and Elsner, 2017); In the research on gait rehabilitation after iSCI, recent randomized clinical trials (RCTs) found no statistical differences between conventional gait training and robotic-assisted gait training. Nevertheless, according to the comparison of effect sizes obtained from these training, these trials suggested that the conventional training approach leads to larger improvements in gait capacity when compared to robotic-assisted therapy (Field-Fote and Roach, 2011; Nooijen, Ter Hoeve, and Field-Fote, 2009). Therefore, these trials highly recommended further research considering these aspects. However, in clinical settings, the implementation of such systematic and intense training sessions remains challenging. The present study aims to test the hypothesis that conventional training might have larger effect sizes on gait capacity and to evaluate the feasibility of such systematic training in a clinical setting of inpatient rehabilitation. Objectives: To contribute to the current knowledge on best clinical practice in gait rehabilitation within the iSCI population. More specifically, the study objectives are two-fold: A first objective is to compare the effects of conventional training, end-effector based therapy and the combination of these interventions on the gait ability of iSCI. A second objective is the evaluation of the feasibility of systematic gait training protocols in a clinical setting. Participants: Individuals with motor incomplete spinal cord injury (iSCI), presenting a traumatic or non-traumatic iSCI with an injury onset <6 months. Intervention: Participants will be trained in one of the three groups by trained physical therapists during 10 sessions, 3x/week with an average duration of 30 minutes. Outcomes: To attain the first objective the effects will be quantified by the following main outcomes: Walking capacity (independence), walking speed, and safety. Feasibility of the systematic intervention will be evaluated using the drop-outs of therapy interventions.

Purpose of the study: To analyse the effectiveness of aquatic physiotherapy on spinal cord injuries (LMi) in the improvement of balance and gait, in the inflammatory profile, and the impact on the quality of life. Main objective: To analyse if there are differences in the recovery of the balance, in incomplete subacute spinal cord injuries, with lesion level T1-L5 and ASIA (American Spinal Injury Association) C and D . Secondary objectives: functional gait To evaluate if the time from the injury to the start of the aquatic therapy influences the results on balance and functional gait. To study the effect of aquatic therapy on serum markers of systemic inflammation. Quality of life related to health. Design: Crossed, controlled and randomized clinical trial, with blind evaluation of the response variables. Scope of the study: National Hospital of Paraplegics. Toledo (Spain). Population: Subjects with incomplete spinal cord injury ASIA C and D. n = 50 (25 in each arm randomly). Intervention: 6 weeks of specific Aquatic Physiotherapy (3 times a week). Group 1 will perform aquatic physiotherapy at the time of entering the study, and group 2 will perform it 6 weeks later. Outcomes: Static and dynamic balance (Berg test and Time Up and Go). Speed of the gait (test of 10 m.). Gait resistance (6 min. Test). Functional capacity of the gait (WISCI II). Biomechanical analysis (sensorial-dynamic, rhythmic and directional control, and gait test) by posturography. Questionnaires EuroQol-5Dimensions-5Level (EQ-5D-5L) and the Spanish Version of the Quality of Life Index (SV-QLI) in spinal cord injury (SCI). Biomarkers of inflammation: 20 cytokines. Analysis of results: The main outcome measure will be the percentage of patients who have improved. Considering improvement when the difference between the groups is, at least, a 10% of their score in the Berg test between V0 and V1 (with their corresponding 95% confidence intervals). It will be adjusted for confounding and interaction factors with a multivariate analysis using logistic regression. All analyses will be performed according to the intention to treat principle.

The purpose of this study is to compare energy expenditure and metabolic outcomes of a novel seated battle rope protocol to seated maximal ramped upper extremity ergometry protocol in subjects with spinal cord injury.

This study will utilize short duration and mild levels of reduced oxygen (hypoxia) to induce spinal plasticity while evaluating the appropriate timing schedule for this intervention, as well as, the effects of superimposing sessions of a therapy, in individuals with chronic incomplete SCI. Our aim is to establish the time-course of outcome improvement and decay following a single session or multiple sessions of AIH therapy.

This is a pilot study to collect data to support a VA grant submission to study fMRI and neurophysiological predictors of hand function and recovery during a robotic intervention in people with hand impairments due to stroke or spinal cord injury.

Chronic pain is prevalent and disabling in people with spinal cord injury (SCI). Medications alone often do not cure the pain. Pilot research suggests that training in the combination of self-hypnosis and cognitive therapy (HCT) can reduce chronic SCI-related pain. Thus far, people have learned HCT only through in-person training sessions plus home practice. The investigators think that training in HCT could be as effective if the training is done via videoconferencing. The purpose of this study is to find out whether people who are trained in HCT via videoconferencing achieve significant pain relief and other benefits compared to people who receive usual medical care (UC) for pain. Bettering our understanding of videoconferencing-delivered HYPNOCT can greatly increase treatment accessibility for individuals with SCI. Aim 1: To compare the efficacy of HYPNOCT vs. UC in adults with SCI and chronic pain. Investigators will compare the effect of the intervention on patient-reported average daily pain as measured by a 0-10 numerical rating scale. Aim 2: To examine sex, race/ethnicity, and pain type (neuropathic vs. non-neuropathic) as potential effect modifiers. Hypotheses Primary study hypothesis Hypothesis 1a: There will be a significantly greater reduction in average daily pain intensity from baseline to the end of treatment in the HYPNOCT group compared to the UC group. Secondary study hypotheses Hypothesis 1b: Compared to the UC group, participants in the HYPNOCT group will show greater improvement in pain interference, depression, sleep quality, subjective disability, health-related quality of life, community participation, pain catastrophizing, pain acceptance, and global improvement. Hypothesis 2: The investigators will examine whether sex, race/ethnicity, and pain type (neuropathic vs. non-neuropathic) exert a modifying effect upon outcomes.

Despite being studied less than half as frequently, autonomic dysfunction is a greater priority than walking again in spinal cord injury. One autonomic condition after spinal cord injury is orthostatic hypotension, where blood pressure dramatically declines when patients assume the upright posture. Orthostatic hypotension is associated with all-cause mortality and cardiovascular incidents as well as fatigue and cognitive dysfunction, and it almost certainly contributes to an elevated risk of heart disease and stroke in people with spinal cord injury. In addition, autonomic dysfunction leads to bladder, bowel, sexual dysfunctions, which are major contributors to reduced quality and quantity of life. Unfortunately, the available options for treating this condition, are primarily limited to pharmacological options, which are not effective and are associated with various side effects. It has been recently demonstrated that spinal cord stimulation can modulate autonomic circuits and improve autonomic function in people living with spinal cord injury. Neuroanatomically, the thoracolumbar sympathetic pathways are the primary spinal cord segments involved in blood pressure control. Recently, a pilot study has been published demonstrating that transcutaneous spinal cord stimulation of thoracolumbar afferents can improve cardiovascular function. However, some studies have shown that lumbosacral transcutaneous spinal cord stimulation can also elicit positive cardiovascular effects. Therefore, there is no consensus on the optimal strategy in order to deliver transcutaneous spinal cord stimulation to improve the function of the autonomic system, and it may be that lumbosacral (i.e. the stimulation site being used most commonly for restoring leg function is sufficient). Another key knowledge gap in terms of transcutaneous spinal cord stimulation is whether or not the current is directly or indirectly activating these spinal circuits. Last but not least, the effects of epidural spinal cord stimulation on the function of cardiovascular, bladder, bowel and sexual system in spinal cord injury have been investigated in no study yet. AIMS AND HYPOTHESES: Aim 1. To examine the effects of short-term (one session) transcutaneous spinal cord stimulation on the frequency and severity of episodes of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. These effects will be compared at two sites of stimulation. Hypothesis 1.1: Short-term transcutaneous mid-thoracic cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 1.2: Lumbosacral transcutaneous spinal cord stimulation will improve bladder, bowel, and sexual functions. Aim 2. To examine the effects of long-term (one month) transcutaneous spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 2.1: Long-term stimulation of the mid-thoracic cord will result in sustained improvements in mitigated severity and frequency of orthostatic hypotension/autonomic dysfunction that is not dependent on active stimulation. Hypothesis 2.2: Long-term lumbosacral transcutaneous spinal cord stimulation will result in sustained improvements in bowel, bladder, and sexual function that is not dependent on active stimulation. Aim 3: To examine the effects of short-term (one session) epidural spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. Hypothesis 3.1: Epidural spinal cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction and improve bladder, bowel, and sexual function. Hypothesis 3.3: There is no significant difference between immediate effects of lumbosacral transcutaneous spinal cord stimulation and epidural spinal cord stimulation on bladder, bowel, and sexual function. For aim 1, 14 participants with spinal cord injury and no implanted electrodes on the spinal cord will be recruited. Participants will randomly receive one-hour stimulation under each of the two stimulation conditions in a crossover manner: Mid-thoracic and Lumbosacral. For aim 2, 28 individuals with spinal cord injury and no implanted electrode will be pseudo-randomized (1:1) to one of two stimulation sites. Participants will receive one-hour stimulation, five sessions per week for four weeks. Cardiovascular and neurological outcomes will be measured before the first stimulation session and after the last stimulation session. For aim 3, 4 participants with spinal cord injury with implanted electrodes on the spinal cord will be recruited to study the immediate effects of invasive epidural spinal cord stimulation. All outcomes will be measured in two positions: a) Supine, b) ~ 70° upright tilt-test. Additionally, bowel, bladder, and sexual functions in project 2 will be assessed weekly.

Over 85,000 Canadians live with a spinal cord injury (SCI). The vast majority experience chronic pain from neuropathic or musculoskeletal origins, with many reporting the pain to be more physically, psychologically and socially debilitating than the injury itself. Currently, pharmaceuticals are the front line treatment recommendation for SCI pain, despite having many side-effects and giving minimal relief. Alternatively, studies conducted in controlled lab and clinical settings suggest that exercise may be a safe, effective behavioural strategy for reducing SCI-related chronic pain. Two ways in which exercise may alleviate pain are by reducing inflammation and increasing descending inhibitory control. To date, no study has tested the effects of exercise, performed in a home-/community-setting, on chronic pain in adults with SCI. Furthermore, information on the exercise dose required to alleviate chronic SCI pain is virtually non-existent, making it impossible for clinicians and fitness trainers to make evidence- informed recommendations regarding the types and amounts of exercise to perform in order to manage SCI pain. Recently (2018), an international team published two scientific SCI exercise guidelines: one to improve fitness and one to improve cardiometabolic health. These scientific guidelines have been translated into Canadian community SCI exercise guidelines and provide the exercise prescription for the proposed study. The investigators' overarching research question is: can home-/community-based exercise-prescribed according to these new SCI exercise guidelines and supported through a theory-based behavioural intervention- significantly reduce chronic pain in adults with SCI?

The investigators have spent the last decade uncovering unique metabolic and functional abnormalities in the brains of patients with spinal cord compression. Degenerative spinal cord compression represents a unique model of reversible spinal cord injury. In the investigator's previous work, they have demonstrated that cortical reorganization and recruitment is associated with metabolic changes in the brains of patients recovering from spinal cord compression and is correlated with recovery and improved neurological scores. The goal of this study is to combine a rigorous platform of clinical care that includes preoperative evaluation, surgery, and rehabilitation, with state of the art imaging techniques to demonstrate how rehabilitative therapy can increase brain plasticity and recovery of neurological function in patients with spinal cord injury. Neurological function will be carefully evaluated in two groups of patients, those receiving rehabilitation and those not receiving rehabilitation after spine surgery, and will be correlated with the results of advanced imaging.
