First artificial leg capable of transmitting feelings to the brain like a real limb was pioneered by researchers in Austria. It also stops phantom pain, a condition that many amputees suffer from.
Professor Hubert Egger, from the University of Linz, Austria, who in 2010 also unveiled a mind-controlled prosthetic arm was the one bloomed in the research.
The leg works by fitting six sensors to the sole of a lightweight prosthesis and then connecting these to the remaining nerve endings in a patient’s stump, which are in turn rewired to healthy tissue in the patient’s thigh. These sensors impulse the brain that there is a foot and the wearer has the impression that it rolls off the ground when he walks.
The first person to receive was Mr. Wolfgang Rangger who lost his right leg after suffering a cerebral stroke, and who has spent the last six months trying out the new leg, says it has completely changed his life.
