New device lets spinal injury patients stimulate nerves at home to improve hand use
NCT ID NCT06850363
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a device called ExaStim that uses mild electrical stimulation on the skin over the spinal cord to help people with chronic cervical spinal cord injury improve arm and hand function. Thirty-three participants used the device at home for 4 weeks after a training period. The main goal was to check safety and see if the device helps with daily activities like eating or dressing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ExaStim Stimulation System (transcutaneous spinal cord stimulation device)
- What this could lead to
- If successful, this device could offer a convenient home-based way to improve arm and hand function for people with spinal cord injury.
- What could go wrong
- This was a small, early observational study with only 33 participants and no comparison group, so results may not apply to everyone. The device may not work for all injury types or severities.
