The Nintendo Wii has done what no other game system has done before. It has helped tens of millions of gamers get into shape.

Now, the New England Journal of Medicine has published an article stating it may be ushering in a new wave of gaming-related injuries.

“Wiitis” as it’s called, is the new wave in game injury, taking it’s place along side of “Nintendo thumb” or Nintendinitis, a form of repetitive strain injury first noticed in heavy gamers over ten years ago. The Wii’s innovative control systems are causing injuries all over their bodies.

Falling off the Wii Balance Board seems to be the main cause of injury. Though the board is only a few inches from the ground, a mishap can still lead to anything from soft-tissue damage to broken bones. Injuries can also result from playing Wii games in confined spaces, and getting hit with a non-restrained controller.

However, the Wii’s emphasis on active gaming clearly encourages the otherwise sedentary to get up off the couch and get moving. The Wii is aiding in the fight against obesity, heart disease and diabetes.

Considering the injuries that one could sustain from bicycling, Kayaking or a walk in the park, I think the risks using a Wii are acceptable.
