Feeling legs again improves amputees’ health

Two volunteers are the first above-knee amputees in the world to feel their prosthetic foot and knee in real time. Their bionic prosthesis, which was developed by an international team of researchers, features sensors that connect to residual nerves in the thigh. The resulting neurofeedback greatly reduces physical and mental strain for users of the prosthesis, as well as their phantom limb pain, while increasing their confidence and speed when walking.
