Bionic leg has moved closer after promising control by amputees

摘要

FOUR AMPUTEE PATIENTS (three men and one woman) have been able to perform various leg and foot movements in a virtual environment using signals from the muscles of their upper legs. The amputees had electrodes placed on the skin's surface over nine muscles in the upper leg. Their performance was roughly comparable to that of four participants with intact limbs. Real-time tests were performed where all participants were instructed to move a virtual lower limb through a variety of motion patterns on a computer screen.
