Scientists test 'Bionic' legs that restore natural movement and feeling

This study tested a new approach to help people with below-knee amputations control a prosthetic leg more naturally. It involved a special surgical technique that connects muscles in the residual limb, paired with a smart 'bionic' prosthesis. Researchers compared 14 people who had this new surgery to others with standard amputations to see if it improved their ability to move the prosthetic ankle and foot and gave them a better sense of where their limb was in space.
