An apparatus, a method, and a computer program product for use in performing, monitoring, and evaluating the performance of therapeutic exercises. The apparatus includes a human-device interface and a motion sensor. In response to movement of the human-device interface, a controller receives motion data from the motion sensor, and transmits the motion data to a computing device. Based on the motion data, the computing device displays a graphical element that depicts the movement. The computing device compares the movement to a target motion, and if the movement matches the target motion, displays a graphical element indicating an exercise is being performed properly. If the movement does not match the target motion, the computing device indicates the exercise is not being performed properly and displays another graphical element indicating how to correct the motion.
