Here is reason number 5,288: In Early Tests, $99 Wii Balance Board Outperforms $17,885 Medical Rig
...doctors at the University of Melbourne found that the balance board, normally used for pseudo Yoga or navigating Mii's down a virtual ski slope, was so sensitive it could very well replace traditional laboratory-grade "force platforms" doctors use to assess a patient's balance.Putting "military grade" on anything and selling it to the DOD often would produce items like the infamous $600 hammers and $1000 toilet seats. Obviously military vendors have a strong competitor in the "suitable for medical use" industry for the crown of who fleeces us more.
When doctors disassembled the board, they found the accelerometers and strain gauges to be of "excellent" quality. "I was shocked given the price: it was an extremely impressive strain gauge set-up," said lead researcher Ross Clark, in an interview with New Scientist.
Even better, Clark's team has already published a paper that verifies the Wii balance board is "clinically comparable" to the nearly $18,000 lab force platform...
