Virtual games and "video game therapy"

Nintendo has created yet another video game to no one's surprise : Wii. This is not the usual sit-on-the-couch-and-exercise-that-opposable-thumb-that-evolution-gave-you kind of game, but one where you actually move around and "imitate" the move in the game. Users have actually complained of "soreness, aching backs, etc" because of the exercise. This video game is now being considered for weight loss programs and for therapy for children with hemiplegic cerebral palsy (children with only one side of the body partially parlyzed) to encourage using both sides of the body (it should improve motor functions in the weaker side).
