Shock to the system: can zaps help stroke survivors walk again?
NCT ID NCT07211672
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a device that sends mild electrical pulses to leg muscles can help people who had a stroke 6-12 months ago walk better. Five participants will complete 24 gait training sessions over 8-12 weeks. Researchers will measure changes in walking speed, endurance, and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Multichannel functional electrical stimulation device (Neuroskin)
- What this could lead to
- If it works, this could point toward a new therapy to help stroke survivors walk faster and with more confidence.
- What could go wrong
- This is a very small, early study with only 5 people. It may not show clear benefits, and results may not apply to all stroke survivors.

Inclusion Criteria: * First ischemic stroke or first hemorrhagic supratentorial stroke * Stroke must be unique * Stoke event in the last 12 months but no sooner than 6 months (post subchronic stroke phase) * Able to walk with the support of one person and one or multiple walking aids (new functionnal ambulatory classification equal to 1, 2 or 3) * Able to tolerate and respond to electrical stimulation(Muscle strength grading level 3 while having the quadriceps stimulated) * Willing to delay anti-spastic treatments like botulinic toxins and motor blockers until the end of the rehabilitation period included in the protocol Exclusion Criteria: * Multiple strokes * Does not respond sufficiently to electrical stimulation * Contraindication to electrical stimulation * Comprehension, psychiatric or cognitive problems that could hamper the protocol * Bilateral stroke or subtentorial stroke * Able to walk without the support of one person (new functionnal ambulatory clssification equal to 4 or more) * Needing help from more than one person to walk (new functionnal ambulatory classification equal to 0) * Moderate spasticity in one or more lower body muscle groups (Modified Ashworth Scale Score \>= 2)
