Smartphone and 3D Printing Based Home Rehabilitation System for Chronic Stroke

mRehab (mobile Rehab) was created to better support in-home upper limb rehabilitation programs. It incorporates a task-oriented approach and immediate performance-based feedback. mRehab consists of 3D-printed household items (a mug, bowl, key, and doorknob) integrated with a smartphone and an app. The app guides participants through practice of activities of daily living (ADL), for example, sipping from a mug. It can also consistently measure time to complete an activity and quality of movement (smoothness/accuracy) during the performance of ADLs. In each session of exercise participants receive feedback on the number of repetitions they complete for each activity, the average time to complete the activity and the average smoothness to perform the activity. Participants were trained in use of mRehab in lab visits and then took mRehab home to use the system. mRehab recorded longitudinal data.
