Scientists finally create a prosthetic leg that lets amputees FEEL

Scientists have created a prosthetic leg which amputees can really feel. While prosthetic limbs are far more advanced than in the 20th century, their major flaw is that they are not really part of someone's body. Amputees cannot feel them, so are at constant risk of falling, needing to concentrate and must keep an eye on the leg's position at all times. Now researchers have solved the problem, allowing people to feel every time their prosthetic foot hits the ground or knee bends to walk. Their new prosthetic leg does this by sending electrical signals to four electrodes surgically implanted into the tibial nerve in someone's thigh.
