Brief summary
The study aims to investigate the relationship between post-stroke adults' movement patterns and disability levels. Utilizing the functional electrical stimulation (FES) system for individualized dorsiflexor and plantar flexor assistance during gait cycles. The investigators will analyze the cycles with and without the FES system. Initially, the context-aware motion assessment and neuroprosthetic control in a clinic will transition to in-home settings as the study progresses, broadening its application for safe and effective use at home.
Interventions
DEVICEFunctional electrical stimulation
The FES system will be placed on the plantar flexors, dorsiflexion, and quadriceps muscles and be paired with the machine learning directed inertial measurement units.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Apply functional electrical stimulation to the paretic limb of muscles of poststroke patients | 1 deployment visit in the laboratory, approximately 4 hours | Control functional electrical stimulation applied to paretic limb muscles of patients with post-stroke hemiparesis. Based on walking-related activities, the resulting controller will stimulate the target muscle groups with properties and amplitude. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Accurate motion assistance while using the functional electrical stimulation in the laboratory. | 1 deployment visit in the laboratory, approximately 4 hours | Limb movement will be accurately detected and supplemented with functional electrical stimulation in the laboratory setting. |
| Accurate motion assistance while using the functional electrical stimulation in the home. | 1 deployment visit in the home, approximately 4 hours | Limb movement will be accurately detected and supplemented with functional electrical stimulation in the home setting. |
