Shock to the system: electrical zaps may boost stroke recovery
NCT ID NCT05240716
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a 24-session program of functional electrical stimulation (FES) on the tibial nerve could improve walking in people who had a stroke more than a year ago. Fifteen participants with chronic stroke and leg weakness were enrolled. The main goal was to see if their walking speed increased after treatment.
