Nerve implants could give amputees better control of robotic legs

This early study tests whether small implants placed on nerves in the thigh can help people with above-knee amputations control a robotic leg more naturally and feel sensations from it. Three participants will undergo surgery to create regenerative nerve interfaces and have electrodes implanted. Over a year, researchers will measure signal strength, movement accuracy, and sensory feedback. The goal is to improve function and quality of life, but the trial is very small and the electrodes are removed after the study.
