Can Video Games Help Stroke Victims?

Disclaimer: I tried to get through the article, I really did, but there was just too much fluff.

My father had a stroke about two years ago that left him without much use of his left arm. Has anyone seen any success from this or other non-standard treatments? It's very discouraging being told by your doctor that the functionality is gone and you'll never get it back, no matter how hard you work.
