Rehabilitation specialists have taken to Nintendo’s Wii game console as a way to help motivate patients during physical therapy and rehabilitation. The latest addition to the Wii-hab phenomenon is perhaps its coolest—Air Guitar Hero. Researchers at Johns Hopkins University have made the popular Guitar Hero game into a tool for amputees who are being fitted with the next generation of artificial arms. With a few electrodes and some very powerful algorithms, amputees can hit all the notes of Pat Benatar’s “Hit Me With Your Best Shot” using only the electrical signals from their residual muscles.
