Spinal implant aims to restore leg movement in groundbreaking 2-person trial
NCT ID NCT05966896
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a surgically implanted device that sends electrical pulses to the spinal cord can help people with spinal cord injury regain voluntary leg movement. Only 2 participants with specific injury levels and MRI evidence of spared nerve fibers will be enrolled. The goal is to gather early safety and effectiveness data to guide future research.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- implanted epidural stimulator (a device that sends electrical pulses to the spinal cord)
- What this could lead to
- If it works, this could point toward a way to help some people with spinal cord injury regain voluntary leg movement.
- What could go wrong
- This is a very early, tiny study with only 2 people. It is designed to test feasibility, not prove effectiveness. The device requires surgery and may not work for everyone.
