the Washington Post, athletic trainers at the University of Maryland and Ohio State University have found a tool to help diagnose and monitor players' dome-piece health: Wii Fit.
Trainers at the two universities now require players to use the Wii Balance Board to get a baseline reading of their -- what else? -- balance. When a player suffers a fairly nasty blow to the head region, they can take another Wii Fit test to see if their balance has deteriorated -- one of the telltale signs of a concussion. Man, combine this test with the Vitality Sensor, and the Wii will become a one-stop-shop for sports-related injury diagnoses!
