Adrian Peterson who has, "one of the most important knees in the NFL," is currently going through rehab, and he's using video games to help.

If you check out this video about Adrian Peterson's recovery, you will see him using the Wii Balance Board and Wii Fit to help normalize his knee, but you will also see a few video custom designed for the explicit purpose of rehabilitation and working out. It's pretty interesting stuff, and honestly something I wouldn't mind seeing at a consumer level. I know I could see myself a little more interested in working out if I was fighting against a high score.
