OnTrack Rehab is a new digital rehabilitation platform that pairs wearable technology with clinical expertise to support patients in the management of their recovery after stroke. OnTrack enables passive tracking of arm movement that is specific to stroke and provides a window into activity data that is otherwise invisible. The platform combines data insights with evidence-based, tailored support to create a unique recovery program for the user. OnTrack has been created in close collaboration with stroke survivors, therapists and world-leading neurorehabilitation experts. OnTrack users have shown a mean increment of 20% in arm activity during pilot testing.
