About the study

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.

What is being tested

• Model-Predictive Controller (MPC) Functional Electrical Stimulation (FES) (device)
• Conventional Functional Electrical Stimulation (FES) (device)
