Wii used as part of rehab

Heidi Mackenzie may look like she's just having a bit of competitive fun, but she and her boxing partner are engaged in a serious form of rehab.

Last summer, Heidi was in a car accident that left her paralyzed from the waist down. She broke her arm and could barely move it, but after sessions with Wii, she has regained strength in her shoulder. (CNN)
