Exercise-primed Upper Extremity Motor Practice in Chronic Stroke

"Subjects will perform 15 minutes of aerobic exercise on a recumbent stationary cycle. On each session the target intensity of aerobic exercise will be 70% heart rate reserve.~Following a 10-minute rest break subjects will perform 200 repetitions on an upper extremity rehabilitation game called Duck Duck Punch (DDP). Duck Duck Punch is an interactive game with an old school carnival theme. DDP is unique as it uses Microsoft Kinect skeletal tracking technology to assess movement performance. The participant sits in front of the Microsoft Kinect and controls a virtual arm with his/her physical arm; reaching forward to punch virtual ducks. A therapist will oversee the subject's safety and progress during DDP. DDP will be dosed based on the number of repetitions performed. A repetition is recorded when the player moves his/her arm so that the avatar leaves a start position. The goal dose for subjects will be 200 repetitions per DDP session."
