"Just trying to exercise and get stronger," he said. "Most of my therapy is, you know, doing repetitions of stuff." But Voltin, 56, from Ramsey, is no ordinary therapy patient. You could call him a ninja warrior, using virtual reality games to rehab his body, partially paralyzed from the neck down. KSTP "The game that I've been playing is called 'fruit ninja,'" Voltin said, smiling. "It gives me a chance to just kind of play and have fun, and use the muscles that hopefully I don't use as regularly as when I'm just doing exercises."
