Muscle activity measured by contractions per minute a, mean amplitude b, and contraction length c. Activity of five upper extremity muscles from the participant’s affected limb were tracked every 1–4 days during acute and inpatient rehabilitation. Muscle activity was evaluated based on activity type: ‘In Room’, ‘In OT’, and ‘In PT’ (columns). Contractions between 100 and 500 ms in length were analyzed in contractions per minute (CPM) (a), median amplitudes normalized across activity type (b), and by contraction length (c). Missing data are due to therapy schedules, sensors falling off participant, or sensor failure.
