In the future, people might choose to replace a painful, arthritic, semi-functional "real" leg with a fully-functional, pain-free bionic one
Researchers at Vanderbilt University have developed a bionic leg that has powered knee and ankle joints, making it much easier to move around than traditional non-powered leg prosthetics. "The prosthetic also features microprocessors that check and predict the movements of the person," according to Techfever.net.
"This means that the bionic leg moves according to the other movements of the person. It's like the prosthetic can "read" what the other leg or the whole body is saying."
MIT roboticist Hugh Herr, speaking at a conference earlier this year organized by The Economist, said disabilities were merely conditions that continue simply "because of poor technology," and prognosticated that disability would mostly be eliminated during the 21st century.
