Innovative Closed-loop Functional Electrical Stimulation Control System for Augmenting Post-stroke Gait

Recruiting now · Not applicable

Conditions studied: Post-stroke Hemiparesis

In brief

This study will compare the performance of a novel data-driven model-predictive controller (MPC) based functional electrical stimulation (FES) system versus a conventional FES system for footdrop correction during treadmill and overground walking tasks in people post-stroke.
