New Prostheses and Orthoses STEP UP Their Game

Forty years ago, Les Baugh lost both of his arms in an electrical accident. With bilateral shoulder-level amputations, his options for prosthetic arms were limited. That changed two years ago, when Baugh underwent a surgical procedure at Johns Hopkins Hospital in Baltimore that allowed him to control state-of-the-art robotic arms using nerves that had been rerouted to his chest. Within ten days of training, he was able to control both arms simultaneously and move a cup from a lower shelf to a higher shelf-a task that previously had been impossible-just by thinking about how he wanted to move his arm. © 2016 IEEE.
