Controlling your ankle with your hamstring
Targeted muscle reinnervation, developed in 2009 by doctors Gregory Dumanian and Todd Kuiken, is a groundbreaking approach to more natural artificial limb movement that rewires remaining nerves in an amputee's residual limb to healthier muscle tissue, essentially rerouting the end destination of one's thoughts.
For Zawter, the RIC bionics team took "nerves that would have gone down to his ankle and rewired them to his hamstring," explained Dr. Annie Simon. The result was that when Zawter thought about moving his ankle, the nerve -- rewired to his hamstring muscle -- felt the contraction, and attached electrodes translated that into foot movement for the bionic limb.
