This study looks at whether everyday rehabilitation therapy sessions can be recorded and measured in a more complete, objective way. Today, therapists usually document sessions by hand, and the notes can vary a lot from one therapist to another. This makes it hard to track exactly what was done during a session and how much effort it took.

In this study, adults receiving neurorehabilitation (for example after a stroke, or with Parkinson's disease, cerebral palsy, spinal cord injury, or ALS) wear two small, non-invasive wrist sensors during their normal therapy. The sensors measure things like heart rate, breathing, skin temperature, and movement. A camera records body movement during the session, and the therapist can turn on an audio recorder that captures their spoken instructions. After each activity, participants rate how hard it felt.

Nothing about the therapy itself changes. The sensors, camera, and audio recording are used only to collect information - they do not guide treatment or affect any clinical decisions. Each participant takes part in three routine therapy sessions.

The goal is to find out whether this combination of sensor, video, and voice information can be collected reliably during normal care, and to compare how the recorded effort matches what therapists and patients report. The study does not provide direct medical benefit to participants, but it may help make future therapy documentation more consistent, objective, and less time-consuming for therapists.
