Clinical Investigation on Feasibility and Usability of the ABLE Exoskeleton Device for Individuals...
Spinal Cord InjuriesThe loss of the ability to walk and the associated restriction of mobility presents a major challenge to people with spinal cord injury in an everyday environment designed for pedestrians. Exoskeletal technology has the potential to help people with impaired leg function to regain ambulation and thus improve their independence. This technology is not completely new, but due to their high access price (~120k€/unit), high size and weight (~25 kg), and need for trained physiotherapist supervision, commercially available exoskeletons are only found in large hospitals and only in very few cases get into patients' homes. The company ABLE Human Motion S.L. (Barcelona, Spain) has developed a novel exoskeleton to overcome these disadvantages, which is more compact, lighter and easier to use. The primary objective of this study is to determine the feasibility and usability of the ABLE Exoskeleton for persons with SCI to perform skills in home and community environments.
Exoskeleton-assisted Walking in SCI Inpatient Rehabilitation
Spinal Cord InjuriesInpatientsTo assess how safe the exoskeleton, EksoGT, is to use for acute inpatient rehabilitation, if it helps people to walk better than with traditional walking training methods, or if they have any other effects (better or worse) on recovery.
Brain and Nerve Stimulation for Hand Muscles in Spinal Cord Injury and ALS
Spinal Cord Injury (SCI)Amyotrophic Lateral Sclerosis (ALS)Most neurological injuries such as spinal cord injuries (SCI) and amyotrophic lateral sclerosis (ALS) spare a portion of nerve circuitry. Strengthening spared nerve circuits may be an important method to improve functional recovery. In this study, the investigators aim to use non-invasive magnetic and electrical stimulation to strengthen motor circuits between the brain and hands. Magnetic stimulation will be used over the motor cortex (scalp). Two methods of electrical stimulation will be compared: stimulation of the median nerve at the wrist; or direct stimulation of the cervical spinal cord across the skin on the back of the neck. Several different combinations of magnetic and electrical stimulation will be compared to find the conditions that best strengthen nerve circuits between the brain and hands - "Fire Together, Wire Together". PLEASE NOTE, THIS IS A PRELIMINARY STUDY. This study is testing for temporary changes in nerve transmission and hand function. THERE IS NO EXPECTATION OF LONG-TERM BENEFIT FROM THIS STUDY. If we see temporary changes in this study, then future studies would focus on how to prolong that effect.
Musculoskeletal Plasticity After Spinal Cord Injury
Spinal Cord InjuriesPatients with spinal cord injury (SCI) experience metabolic syndrome, diabetes, obesity, pressure ulcers, and cardiovascular disease at far greater rates than the general population. A rehabilitation method to prevent or reverse the systemic metabolic consequences of SCI is a pressing need. The purpose of this study is to determine the dose of muscle activity that can enhance an oxidative muscle phenotype and improve clinical markers of metabolic health and bone turnover in patients with SCI. The long-term goal of this research is to develop exercise-based interventions to prevent secondary health conditions such as diabetes and to ultimately protect health-related quality of life (QOL). Specific Aim 1: To compare changes in skeletal muscle gene regulation in individuals who receive high frequency (HF) active-resisted stance and low frequency (LF) active-resisted stance for 3 years. Hypothesis 1: The expression of genes regulating skeletal muscle metabolism will support that HF and LF both instigate a shift toward an oxidative muscle phenotype. A novel finding will be that LF is a powerful regulator of oxidative pathways in skeletal muscle. Specific Aim 2: To compare changes in systemic markers of metabolic health and bone turnover in individuals with SCI who receive HF or LF for 3 years. Hypothesis 2: HF and LF will both reduce glucose/insulin levels and HOMA (homeostasis model assessment) score. Secondary Aim: To measure subject-reported QOL using the EQ-5D survey metric. Hypothesis 3: HF and LF subjects will show a trend toward improved self-reported QOL after 3 years. There will be an association between metabolic improvement and improved perception of QOL. These observations will support that this intervention has strong feasibility for future clinical translation.
Clinical Trial to Evaluate One-to-one Peer Mentoring
InjuriesSpinal CordThe research will examine the effects of enhanced peer mentor interactions on facilitating a successful transition to community living following traumatic spinal cord injury (SCI). Participants in the research will be assigned to either (1) the control group that will receive traditional peer mentor types of interactions or (2) to the intervention group that will receive an enhanced peer mentor program called the One-on-One Initiative. Assignment to one of these two groups will occur randomly on admission to Shepherd Center; the only stratifying criteria is injury level - C6 and above vs. C7 and below.
Skeletal Muscle Hypertrophy and Cardio-Metabolic Benefits After Spinal Cord Injury
Spinal Cord InjuriesSpinal cord injury (SCI) is a devastating medical problem that affects thousands of civilian and military personnel in the United States. Spinal cord injuries (SCI) predispose individuals to impaired fitness, obesity, glucose intolerance and insulin resistance, placing them at greater risk for diabetes and coronary artery disease. These are devastating problems that occur frequently because of changes in body composition and reduced level of physical activity. Skeletal muscle wasting plays a central role in altered metabolism after SCI. Functional electrical stimulation (FES) is an effective rehabilitation tool that has been used to train the paralyzed skeletal muscles and which has shown some ability to ameliorate the deleterious effects of SCI on metabolism, particularly on insulin sensitivity. However, its ability to reverse skeletal muscle wasting is modest; most studies report limited gains in muscle mass and workload with highly variables outcomes from one study to another. This proposal was stimulated by the findings that a program of neuromuscular electrical stimulation resistance exercise prior to initiating functional electrical stimulation lower extremity cycling (FES-LEC) improves the gains in muscle mass and workload observed with FES. The specific objectives for the current proposal are to compare the impact of FES following evoking skeletal muscle hypertrophy of the lower extremity versus initiating FES cycling without introducing the hypertrophy effects on insulin sensitivity, control of blood sugar levels, oxygen uptake and amounts of muscle tissue and fat deposition. These studies could potentially have significant effects on thousands of people that will experience an SCI in the future as well as those living with SCI where prolonged paralysis is a major quality of life issue. There is a major need to investigate the mechanisms lead to maximize the benefits of FES applications and to understand cellular or molecular events that are associated with muscle hypertrophy and lead to promoting metabolic health after SCI. The designed study will provide a greater understanding regarding utilization of energy sources (like fats and sugars) in muscle
Molecular Markers of Neuroplasticity During Exercise in People With Incomplete Spinal Cord Injury...
Spinal Cord InjuryThe purpose of this study is to determine whether exercising (walking) at different intensities increases levels of factors in the blood and saliva that are known to impact neuroplasticity (how the connections in the spinal cord and brain can change) and if these levels are changed by pairing exercise with a single dose of commonly used prescription drugs or by your mood.
Aerobic Exercise and Blood Biochemical Factors in Spinal Cord Injury
Spinal Cord InjuryBackground: Patients with spinal cord injury (SCI) have a higher prevalence of cardiovascular diseases compared to the healthy population. Aerobic exercise training is one of the recommended treatments. However, literature regarding the effect of aerobic training on patients with SCI is scarce. This study evaluated changes in parameters of exercise physiology and serum myokines immediately after exercise and after a training program among patients with SCI. Method: Male patients with SCI and age- and sex-matched healthy individuals were recruited. Cardio-pulmonary exercise testing (CPET) was used to determine oxygen uptake at peak exercise and anaerobic threshold in both groups. The patients with SCI attended aerobic exercise training for 36 sessions within 12-16 weeks. Basic data, hemodynamic and exercise physiology parameters, and serum myokine (myostatin, insulin like growth factor, and follistatin) concentrations were measured pre- and post-exercise in both groups, and were repeated in patients with SCI post-training.
Exoskeleton Use in Acute Rehab Post Spinal Cord Injury; a Safety and Feasibility Study
Spinal Cord InjuriesThis study will examine the safety and feasibility of using an exoskeleton in subjects who are less than 6 months post spinal cord injury (SCI).
Investigating the Energy Expenditure of Acute Spinal Cord Injured Patients
Spinal Cord InjuryAcuteIt is recognised that weight gain is a common problem in patients with a spinal cord injury and can lead to an increased incidence of metabolic syndrome. Weight gain is thought to be attributed to excess calorie intake, reduction in energy requirements and / or a reduction in exercise. However, further understanding of this energy imbalance needs to be addressed. This feasibility study will initially determine if it is feasible to measure the 'actual' energy requirements of 15 paraplegic and 15 tetraplegic (ventilated and non-ventilated) in-patients during bed rest and rehabilitation following acute SCI. This preliminary data will be compared to 'predicted' energy expenditure levels. The calorie intake and body composition for each patient will be measured as well as factors indicative of metabolic syndrome. The study will initially provide statistical information in order to estimate the sample size required for a future definitive study.
