Will's mom, Mary Margaret Graves, notices another benefit of Wii-hab's effect on her son - motivation.

"It's therapy, but it's fun. It's an added bonus," said Mary Margaret, who describes Will as being competitive his whole life.

"I think it's (Wii-hab) caught fire across the country in nursing homes and rehab facilities because the patients start doing things that they don't realize they were doing and that just helps in their recovery," Mary Margaret said.

"They stand up for so much longer while they're doing something like this rather than just say, 'Ok, let's see how long you can stand?' " Jones said.

"Patients look forward to therapy. They are better engaged," said Suzy Mayer, director of therapy services at Methodist Rehab. Mayer explains the Wii is entertaining, gives immediate feedback, works the fine and gross motor skills and stores information that can be tracked, which thereby measures a patient's progress.
