Finding the Best Combination of Brain and Spinal Cord Stimulation With Hand Training After Spinal Cord Injury
United States12 participantsStarted 2024-05-24
Plain-language summary
While physical exercise remains the foundation for any rehabilitation therapy, the team seeks to improve the benefits of exercise by combining it with the concept of "Fire Together, Wire Together" - when brain stimulation is synchronized with spinal cord stimulation, nerve circuits in the spinal cord strengthen - a phenomenon termed "Spinal Cord Associative Plasticity", or SCAP.
This project will build on the team's promising preliminary findings. When one pulse of brain stimulation is synchronized with one pulse of cervical spinal stimulation, hand muscle responses are larger than with brain stimulation alone or unsynchronized stimulation. However, the team does not know the best ways to apply SCAP repetitively, especially in conjunction with exercise, to increase and extend improvements in clinical function. Do ideal intervention parameters vary across individuals, or do they need to be customized?
The team will take a systematic approach with people who have chronic cervical SCI to determine each person's best combination of SCAP with task-oriented hand exercise. Participants will undergo up to 53 intervention, verification, and follow-up sessions over a period of 6 to 10 months each. The team will measure clinical and physiological responses of hand and arm muscles to each intervention.
Regaining control over hand function represents the top priority for individuals with cervical SCI. Furthermore, this approach could be compatible with other future interventions, including medications and cell-based treatments.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
