Jamey had a surgery on his shoulder early this year, and we bought a Wii game console and a Marble Mania game for his thearpy. Besides the mind dumbing boredom, he really found that holding his arm out and rotating ever so slightly built up the muscles that had been damaged in the surgery. He strengthened those muscles fast and hardly seemed to notice his efforts.
What you have to do with the game, copied from their own advertising;
Using tilting Wii’s motion sensitive Wii Remote with poise and precision, players must seek to navigate their favourite cute and quirky balls, each with their own look and varying benefits, through complex 3D mazes. Therefore no complicated button combinations are necessary, the tactile controls allow players to tip and tilt their environment in all directions, even upside-down to 180 degrees.
