Wiihabilitation is so 2008 and yes, Adrian Peterson of the NFL's Minnesota Vikings is doing some of that as he tries to come back from a devastating injury in American football — the torn anterior cruciate ligament. But what's more interesting here is Peterson has a custom set of exergames to go along with ski jumping on the Wii balance board.
The team, in an official video, calls it "Rehab Arcade". A couple minigames shown have Peterson playing a basic side-scroller and top-down scroller, moving a square block out of the way of some descending balls, or navigating a ball through a series of gates. His movement on the leg press controls movement in the game.
The video isn't embeddable, you'll have to see it at the link. It's somewhat fitting for the Vikings, who have notorious gamer Chris Kluwe (ChrisWarcraft on Twitter) on the roster, and for Peterson, who was introduced to Magic: the Gathering by Kluwe last year.
