Sensing Prosthetic Leg!

People with amputated limbs report what is called “phantom” pain. Nerves in the upper leg above the amputation send error signals to the brain telling it that the foot or lower leg is in trouble. Now prosthetic engineers and doctors have built a new “sensing” prosthetic leg that can pick up pressure points on the foot and knee and then send signals to an implanted spot along the sciatic nerve above the amputation. Patients who have tested the leg say that it is though they have their feeling back and that they have the sensation of having a real leg—and, the phantom pain is relieved!
