Active clinical trials for "Spinal Cord Injuries"

Incomplete spinal cord injuries (SCI) are the most frequent neurologic category, comprising 66.7% of all SCI cases. People with incomplete SCI may retain some ability to move the legs and therefore the capacity to regain walking. Studies that show functional improvement in locomotion via electrical stimulation of lumbosacral circuits suggest that the underlying mechanisms are neuromodulation of lumbosacral spinal cord automaticity and sensory feedback. Both epidural and transcutaneous spinal stimulation are demonstrating exciting potential to improve limb function for people after chronic SCI. Available treatment options for SCI are less than satisfactory and most often do not achieve full restoration of function. Recent experimental results suggest an exciting new approach of using electrical spinal stimulation to enable users to regain control of their weak or paralyzed muscles. Using surgically-implanted electrodes, epidural stimulation results in remarkable improvements of lower extremity function as well as autonomic functions such as bladder function and sexual function. In addition to epidural stimulation, over only the last few years a novel strategy of skin surface electrical spinal stimulation has also demonstrated exciting potential for improving walking function. Using a high-frequency stimulation pulse, current can pass through the skin without discomfort and activate the spinal cord; this results in patterned stepping movements for people without SCI and improved lower extremity function following SCI. This study will directly compare skin-surface transcutaneous stimulation with implanted epidural stimulation for improving lower extremity function.

The study team is currently recruiting volunteers who are interested in participating in a brain-spinal cord-muscle response training study that aims to better understand the changes that take place in the nervous system as a result of this type of training. After spinal cord injury, brain-to-muscle connections are often interrupted. Because these connections are important in movement control, when they are not working well, movements may be disturbed. Researchers have found that people can learn to strengthen these connections through training. Strengthening these connections may be able to improve movement control and recovery after injuries. Research participants will be asked to stand, sit, and walk during the study sessions. Electrodes are placed on the skin over leg muscles for monitoring muscle activity. For examining brain-to-muscle connections, the study team will use transcranial magnetic stimulation. The stimulation is applied over the head and will indirectly stimulate brain cells with little or no discomfort. Participation in this study requires approximately three sessions per week for four months, followed by two to three sessions over another three months. Each session lasts approximately 1 hour.

Impairments of walking function after spinal cord lesion due to, for example, inflammation, ischemia or trauma are exceptionally diverse. Depending on the size, location and completeness of the spinal cord lesion, gait dysfunction is often multifactorial, arising from weakness of leg muscles, sensory impairments or spasticity. Locomotor function in humans with spinal cord damage can be improved through training. However, there are no evidence-based guidelines for the treatment of gait dysfunctions and no excepted standards of gait training in this large and heterogeneous group of patients. A lack of evidence-based guidance and standardisation prevents the development of optimal training programs for patients with spinal cord damage and rather broad and subjective clinical judgement is applied to determine patient care. Objective and quantitative techniques like three-dimensional (3D) full-body movement analysis capable of identifying the most relevant determinants of gait dysfunction at the single-patient-level are not yet implemented as diagnostic tool to guide physical therapy in this heterogeneous group of patients. The objective of this project is to further advance current clinical locomotor training strategies by applying a deficit-oriented gait training approach based on subject-specific, objective gait profiles gleaned from 3D gait analysis in chronic, mildly to moderately gait-impaired individuals with spinal cord damage due to inflammation (in multiple sclerosis, MS) or with traumatic or ischemic spinal cord injury (SCI; motor incomplete). Within a parallel-group clinical trial, gait impaired subjects will be characterized by detailed kinematic 3D gait analysis and either trained according to their individual deficits or treated with non-specific, standard walking therapy for six weeks. It is hypothesized that individually adapted, deficit-oriented training is superior in improving walking function than purely task-related, ambulatory training in patients with spinal cord damage. This project may pave the way to more efficient training approaches in subjects with spinal cord damage by transferring and implementing modern gait assessment techniques into clinical neurorehabilitation and to move towards individual, patient-tailored locomotor training programs.

This is a single-cohort early feasibility trial to determine whether an investigational device called the Bidirectional Neural Bypass System can lead to the restoration of movement and sensation in the hand and wrist of up to three individuals with tetraplegia.

This study will provide nutrition counseling via FaceTime on an iPad to persons with traumatic spinal cord injury (SCI) who are overweight or obese and are at least one-year post-injury. Nutrition counseling may help participants to develop eating behaviors that match the participants' needs and help improve heart health. The purpose of this project is to decrease the risk of complications like obesity, high cholesterol, or diabetes, and explore associations between bowel and bladder function and nutrition. This study will require 3 in person visits that are about 3 months apart. The total length of the study is about 6 months and includes 3 months of telenutrition counseling.

A common problem among children with nervous system disorders is difficulty walking on their own. This has impacts beyond mobility including short and long-term health conditions associated with physical inactivity and different developmental experiences as a result of the mobility impairments. A robotic trainer can both provide rehabilitation and be an assistive device to help compensate for difficulties. Figuring out how to prescribe it is critical to improve daily life for children with significant disabilities. Preliminary use of robotic trainers have shown many benefits, such as better head control and improved independence in transfers, which greatly increases ability to live independently. Additionally, vital functions that are frequently impaired in those with less physical activity, such as sleep and bowel habits, seem to improve. Finally, these children enjoy using them. This project aims to determine who is most likely to benefit from training with a robotic trainer and investigate key details about the dose of training that is needed. Families that are already using or hope to use robotic training need this data to help improve their access to the intervention. Clinicians need this systematic approach to building evidence to ensure a future multi-centre randomized control trial is well designed. This study is needed to help improve the lives of those who live with significant disabilities. The objective is to evaluate the feasibility and impacts of delivering robotic gait training at home. Integral in this study is capturing the user perspectives. This will both provide preliminary evidence-based advice to potential users, their families, and clinicians as well as provide key metrics to design a definitive multi-centre randomized control trial. The investigators will provide robotic gait trainers, specifically Trexo robotic gait trainers, to participants and their families to use in their home communities for 12 weeks to evaluate the feasibility and impacts of intensive robotic gait training in people who cannot walk independently. Assessments will be completed throughout the duration of study, including before, during, and after the training intervention, with the goal of evaluating a wide range of feasibility considerations and impacts from robotic training.

Interventional prospective longitudinal on the evaluation of spinal cord stimulation (SCS) assisted by motor rehabilitation training for restoring motor function in patients with spinal cord injury (SCI). The investigators will enroll ten research participants with clinically incomplete/complete SCI (patients with paraplegia or severe paraparesis) who will undergo SCS subsequently assisted by motor rehabilitation training for restoring motor function at IRCCS Ospedale San Raffaele, Milan, Italy. The main goal of the project is to evaluate the improvement in motor function generated by the combination of SCS and locomotor training. In line with recently published studies, the investigators propose that daily locomotor training in the presence of SCS with continuous stimulation parameters setting will enable the SCI individuals to stand and step independently while bearing full weight.

Spinal cord injury (SCI) is a devastating condition that often leads to paralysis and multiple health problems such as muscle wasting, bone loss and spasticity. Despite the paralysis, functional electrical stimulation (FES) on the skin surface muscles may produce muscle contractions. People who have had an SCI for a long time (chronic SCI) already use FES cycling to exercise, and it is known that it can reverse muscle atrophy and has a wide range of health benefits. Furthermore, animal research suggests that starting exercise training early after new SCI may promote spinal cord recovery. However, not much is known about early FES cycling in humans. Therefore, the investigators propose to study if early FES cycling could prevent muscle wasting, pain or spasticity, and help with spinal cord recovery. The study will recruit 36 participants with a new, acute SCI, between 14 and 21 days after their injury into 3 groups. An Early-FES group starts FES cycling early after injury (between 14 and 21 days after injury), and for a duration of 6 months. A Delayed-FES group starts FES cycling 3 months after enrolling in the study, and for a duration of 3 months. A Control group does not perform FES cycling. This pilot study will allow us to study if early FES cycling, in addition to normal care, has greater benefits on the preservation and recovery of the leg muscles and spinal cord function than delayed FES cycling or standard care only. The results of this pilot study may lead to the development of a larger study with early FES cycling after new SCI.

Acute intermittent hypoxia (AIH) involves short (~1-2min) bouts of breathing low oxygen air to stimulate spinal neuroplasticity. Studies in rodents and humans indicate that AIH improves motor function after spinal cord injury (SCI). This study will use a double blind, cross-over design to test if the combination of AIH and respiratory strength training improves breathing function more than either approach alone in adults with chronic SCI.

The purpose of this study is to validate the capacity of a reflex training system to change the size of the targeted reflex. For this, the researchers are recruiting 25 individuals with chronic incomplete SCI who have spasticity in the leg to participate in the reflex training procedure. The study involves approximately 45 visits with a total study duration of about 6 months.
