Active clinical trials for "Spinal Cord Injuries"

The purpose of this research study is to demonstrate the safety and efficacy of using two CRS Arrays (microelectrodes) for long-term recording of brain motor cortex activity and microstimulation of brain sensory cortex.

Test the feasibility of using electrocorticography (ECoG) signals to control complex devices for motor and speech control in adults severely affected by neurological disorders.

The overall aim of this project is to assess the effect of combining transcutaneous lumbosacral stimulation (TLS) during Exoskeleton Assisted Walking (EAW) compared to EAW alone without stimulation on walking recovery.

The aim of this pilot study is to explore how body composition, circulating markers of metabolic health and skin integrity in persons with a spinal cord injury (SCI) are affected by 12 weeks of quadriceps neuromuscular electrical stimulation (NMES) resistance training. The novel element of this study is that one group will be given additional daily protein supplementation in addition to the NMES training (treatment group), whereas the other group will only perform the NMES training (control group). The investigators hypothesise that NMES in combination with protein results in larger improvements in the aforementioned outcomes compared with NMES alone.

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.

Spinal cord associative plasticity (SCAP) is a combined cortical and spinal electrical stimulation technique developed to induce recovery of arm and hand function in spinal cord injury. The proposed study will advance understanding of SCAP, which is critical to its effective translation to human therapy. The purpose of the study is to: Determine whether signaling through the spinal cord to the muscles can be strengthened by electrical stimulation. Improve our understanding of the spinal cord and how it produces movement. Determine whether spinal surgery to relieve pressure on the spinal cord can improve its function. Aim 1 is designed to advance mechanistic understanding of spinal cord associative plasticity (SCAP). Aim 2 will determine whether SCAP increases spinal cord excitability after the period of repetitive pairing. In rats, SCAP augments muscle activation for hours after just 5 minutes of paired stimuli. Whereas Aims 1 and 2 focused on the effects of paired stimulation in the context of uninjured spinal cord, Aim 3 assesses whether paired stimulation can be effective across injured cord segments. Aim 3 will incorporate the experiments from Aim 1 and 2 but in people with SCI, either traumatic or pre-operative patients with myelopathy in non-invasive experiments, or targeting myelopathic segments in intraoperative segments.

The goal of this project is to strengthen residual corticospinal tract (CST) connections after partial injury using combined motor cortex and spinal cord stimulation to improve arm and hand function after spinal cord injury (SCI). To do this, the investigators will test the combination of transcranial magnetic stimulation (TMS) with transcutaneous spinal direct current stimulation (tsDCS) in individuals with chronic cervical SCI.

Background: People with cerebral palsy, spina bifida, muscular dystrophy, or spinal cord injury often have muscle weakness and problems controlling how their legs move. This can affect how they walk. The NIH has designed a robotic device (exoskeleton) that can be worn on the legs while walking. The wearable robot offers a new form of gait training. Objective: To learn whether a robotic device worn on the legs can improve walking ability in those with a gait disorder. Eligibility: People aged 3 to 17 years with a gait disorder involving the knee joint. Design: Participants will be screened. They will have a physical exam. Their walking ability will be tested. Participants will have markers taped on their body; they will walk while cameras record their movements. They will undergo other tests of their motor function and muscle strength. The study will be split into three 12-week phases. During 1 phase, participants will continue with their standard therapy. During another phase, participants will work with the exoskeleton in a lab setting. Their legs will be scanned to create an exoskeleton with a customized fit. The exoskeleton operates in different modes: in exercise mode, it applies force that makes it difficult to take steps; in assistance mode, it applies force meant to aid walking; in combination mode, it alternates between these two approaches. During the third phase, participants may take the exoskeleton home. They will walk in the device at least 1 hour per day, 5 days per week, for 12 weeks. Participants walking ability will be retested after each phase....

This study is designed is to test the feasibility, fidelity, and effectiveness of scaling up an evidence- and theory-based virtually delivered physical activity intervention (WOWii) for individuals living with chronic SCI for delivery through other rehabilitation settings. The study outcomes address (1) feasibility based on participant enrollment, retention, and program engagement; (2) fidelity of intervention delivery; and (3) program effectiveness based on subjective and objective exercise data, and participant exercise perceptions regarding self-efficacy and barriers.

Reduced arm and hand function has a significant impact on independence and quality of life after spinal cord injury. Functional electrical stimulation therapy (FES-T) is a treatment that can produce improvements in reaching and grasping function after neurological injuries. However, not all paralyzed muscles respond equally well to the therapy. Currently, therapists cannot predict which muscles will respond, limiting their ability to create a personalized therapy plan that can maximize outcomes while making the best use of the limited treatment time available. The objective of this study is to develop a diagnostic method that will allow therapists to quickly and easily screen muscles in the clinic, in order to predict how they will respond to FES-T. Participants with cervical spinal cord injury will receive FES-T through the Rocket Family Upper Extremity Clinic at the Toronto Rehabilitation Institute - University Health Network. Muscles receiving training will undergo a electrophysiological examination before the start of therapy, and will then be tracked for strength recovery over the course of 30 sessions. Lastly, signal processing and machine learning techniques will be applied to the electrophysiological data to predict the recovery profile of each muscle. The significance of this work will be to provide personalized therapy planning in FES-T, leading to more effective use of healthcare resource as well as improved outcomes.
