Abstract: A system and method for developing an individual's physical abilities includes measuring one or more physical ability of an individual and establishing control parameters of a game such that operation of the game at a beginning level is within the individual's measured physical ability. The degree of physical ability shown by the individual over time of game play is monitored, and the control parameters are gradually modified to require a progressively greater physical ability of the individual than required at the beginning level. The system includes an input device, e.g., a joystick, that is operated by the individual to play the game. The system records aspects related to game play, such as frequency and duration of play, specific actions or motions, and changes in physical ability. A therapist is then able to review the record and modify system settings to optimize improvement by the individual.
