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.

| Apply functional electrical stimulation to the paretic limb of muscles of poststroke patients | 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. | 1 deployment visit in the laboratory, approximately 4 hours |

Twenty post-stroke community-dwelling adults will participate in a single in-laboratory and in-home visit, performing 5x sit-to-stand (5XSST), 5x Comfortable and 3x Fast walking speed at a 5M distance, and 5x modified Timed Up and Go (TUG). The tests will be performed twice: once with and without the task aware-neuroprosthesis.
