Active clinical trials for "Spinal Cord Injuries"

This research study is being done to test a new device developed for spinal cord injury (SCI) patients. The purpose of this study is to collect data on how the nervous system signals travel within the spinal cord of SCI patients. Once the investigators understand that, they hope to develop a device that may help rehabilitation of SCI patients so that they can regain function in their lower limbs. This study involves some imaging studies (e.g. X-rays etc.), surgical implantation of a portion of the electrical stimulation device, various assessments of body function (e.g. balance, movement, gait), and physical rehabilitation procedures. What is new and experimental is the stimulation/sensing device (Intelligent Spine Interface - Commercial, ISI-C) that will be implanted.

The purpose of this study is to evaluate a new control (i.e., the vision-guided shared control) for a wheelchair-mounted assistive robotic manipulator among powered wheelchair users. This study will consist of a questionnaire about general demographics, health information, and previous experience with assistive technology. Several tests will also be administered to test upper extremity function and ability as well as to test spatial orientation and visualization ability. Participants till then undergo a training phase with the assistive robotic manipulator mounted on a table to assess if they will be eligible for participation in the study. Eligible participants will move on to a second training phase where they will be asked to learn and practice slightly more complex tasks while using the vision-guided shared controller. After this training the assistive robotic manipulator will be mounted to the participants wheelchair and they will be asked to complete a number of everyday tasks from a task list. At the conclusion of the study, researchers will conduct a brief semi-structured interview with each participant and obtain more insight on how participants perceive the ease-of-use and usefulness of the vision-guided shared control.

Early detection of response to therapeutic intervention is vital, as it will enable early termination of intervention in non-responding patients, prevent unnecessary financial burden, and allow for early changes to the intervention program. Previous functional MRI (fMRI) studies have shown that changes in brain functional network in spinal cord injury (SCI) patients can occur after as little as one week of intervention. Resting state fMRI (rsfMRI) is a type of fMRI that does not require performance of explicit motor tasks, which makes the method especially suitable for SCI patient population. In this project, the investigators propose that rsfMRI outcome measures can be used to detect early brain functional network changes that occur during intervention, and that the changes will be predictive of recovery in chronic SCI patients.

Spinal cord injury (SCI) is a devastating health problem for tens of thousands of military personnel, Veterans and civilians annually. Many persons with SCI must use a wheelchair for their entire life. A new scientific breakthrough called "lumbosacral epidural stimulation" or "ES" can help people with SCI to stand, step and even walk again. At present, for ES to work, people must train with a specialized treadmill that requires several other qualified personnel to train them, which makes it hard for many people with SCI to benefit from this technology. On the other hand, there are wearable "robot suits" that can be used with ES, which would make it easier to use. Our research team has already used this "ES Robot Suit" for 3 months in one person with tetraplegia and showed remarkable improvements in motor control. Furthermore, the investigators are aiming to enhance overground motor recovery by adding 6 months of resistance training (RT). The addition of RT will likely to enhance muscle quality as indicated by increasing lean mass, peak torque and increase sensory flux to the central nervous system. Other additional benefits may include improvement in cardiovascular profile and bladder functions. The specific objectives of the current proposal are to compare the impact of EAW+ES following improving lower extremity muscle quality compared to those who will only undergo EAW+ ES without conducting RT on motor recovery, cardio-metabolic health and bladder control in persons with complete SCI. At the conclusion of the current proposal, the work will be readily available for translation into clinical setting to serve Veterans and Civilian survivors with SCI.

The overall objective of this fully powered clinical trial is to investigate if using a solid backrest on a manual wheelchair (MWC) will improve postural alignment, function and wheelchair mobility, as compared with an upholstery backrest, and to explore the impact of overall back height, contour, and seat gap when using a solid backrest in individuals with spinal cord injury (SCI).

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.

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.

The Synchron motor neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility. The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.

Rehabilitation of functional movements after spinal cord injury (SCI) requires commitment and engagement to the processes of physical therapy. Outcomes may be improved by techniques that strengthen cognitive connections between users and physical therapy exercises. The investigators will investigate combinations of virtual reality and innovative wearable technology to accelerate rehabilitation of hand grasp and reach. These devices use multi-sensory feedback to enhance the sense of agency, or feelings of control, and better train movements during physical rehabilitation exercises. The investigators will measure the effect of these devices on improving the speed, efficiency, and accuracy of performed movements in Veterans with SCI.

The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.
