Video: Bionic Legs for Bilateral Above-Knee Amputations


The Regenstein Foundation Center for Bionic Medicine (CBM) has been developing coordinating bionic legs for people with dual above-knee amputations for more than a decade. This pair of bionic legs uses electromyography (EMG) — a technique for evaluating and recording the electrical activity produced by skeletal muscles — to enable the legs to “talk to each other,” thereby coordinate walking and other movement. Currently, these legs are only available in the research sector but we are hopeful that they will be commercially available in years to come.
