This one's pretty cute (or evidence of a completely uncreative healthcare industry). Researchers at the University of Melbourne and Singapore General Hospital's Department of Physiotherapy have run a battery of tests on the Wii's Balance Board, and found it to be somewhat useful in testing patient's balance and equilibrium, medically speaking. Current medical equipment used to test these skills is very expensive, heavy, and in short supply. The Balance Board, on the other hand, runs about $99. The Wii accessory was tested on 30 patients, and found to be about as good as the expensive force platforms usually used by doctors... which is great news for Nintendo -- this product has seemingly endless real-life applications -- but rather embarrassing for the makers of medical equipment, no?
