High-tech neuroprosthetic 'Luke' arm lets amputee touch and feel again

"When I went to grab something, I could feel myself grabbing it. When I thought about moving this or that finger, it would move almost right away," Keven Walgamott said. "I don't know how to describe it except that it was like I had a hand again." Walgamott was describing the results of an experimental surgery to The Washington Post, where a prosthetic known as the "Luke" arm had been attached with electrodes implanted into his nerves. The real estate agent had lost his hand and most of his arm in an electrical accident 14 years ago, and he volunteered for the program at the University of Utah.
