Stroke arm rehab study halted early – no clear answers yet
NCT ID NCT05570838
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding functional electrical stimulation (FES) to robotic hand therapy could improve arm movement in people who had a stroke within the past year. Researchers planned to compare two groups: one getting standard rehab plus robotic therapy and FES, and another getting only standard rehab plus robotic therapy. However, the trial was terminated early, so we don't have enough data to know if the combination works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Functional electrical stimulation (FES) and hand robotic-assisted therapy (AMADEO robot)
- What this could lead to
- If it had succeeded, this could point toward a more effective rehab approach for improving arm movement after stroke.
- What could go wrong
- The trial was terminated early, so we don't have clear results. It was also a small, early-stage study, so even if completed, findings might not apply to all stroke patients.
