Robot + zaps: new combo therapy boosts arm recovery after stroke
NCT ID NCT05854485
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether combining robotic arm training with functional electrical stimulation (FES) helps people with chronic stroke improve arm movement more than robotic training alone. 24 adults who had a stroke at least 6 months earlier participated. The goal was to see if the hybrid approach leads to smoother, faster, and fuller arm motion.
