Innovative Closed-loop Functional Electrical Stimulation Control System for Augmenting Post-stroke Gait
Sponsor: Emory University
Summary
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.

Model-Predictive Controller (MPC) Functional Electrical Stimulation (FES)
The model-predictive controller (MPC) determines the timing and intensity of electrical stimulation delivered for FES. MPC combined with real-time ultrasound-based feedback delivers optimal FES intensities and minimizes fatigue. FES is delivered to the ankle dorsiflexor muscles using a commercially available FDA-approved electrical stimulator.
Conventional Functional Electrical Stimulation (FES)
For functional electrical stimulation, surface electrodes are placed on the paretic leg on skin overlying the tibialis anterior (TA) muscle, with intensity pre-set to elicit dorsiflexion to neutral against gravity. FES will be delivered to the ankle dorsiflexor muscles using a commercially available FDA-approved electrical stimulator.
