This research study aims to better understand how the brain and body change during physical or occupational therapy after a neurologic injury or condition. Adults who are already receiving outpatient neurorehabilitation will be invited to participate while they complete their regular therapy sessions. During therapy, participants will wear a lightweight cap that measures brain activity and will be video recorded so researchers can analyze movement patterns using computer software. These recordings do not change therapy activities and are for research purposes only. The study does not involve new treatments, medications, or procedures beyond standard care. Information collected may help researchers understand why recovery differs between individuals and improve future rehabilitation approaches.
