“A surgeon placed a sensor on Mumford’s right shoulder, implanted a pacemaker-size device known as a stimulator just below the skin on his upper chest, and threaded wires into the muscles of his left arm. On the outside of Mumford’s body, a wire ran from the shoulder sensor to an external control unit; another wire ran from that control unit to a transmitting coil over the stimulator in his chest.” Thanks to this complex set-up, John Mumford was able to move one of his paralyzed hands for the first time since his van slid off a cliff in 1982. Then the company that created the technology went out of business.
