Breakthrough prosthetic leg enables natural gait with neural control

News-Medical.Net — July 2, 2024, 02:00 AM UTC

Summary: MIT researchers, in collaboration with Brigham and Women's Hospital, have developed a breakthrough prosthetic leg that achieves a natural gait through full neural control. The new surgical intervention, called agonist-antagonist myoneural interface (AMI), reconnects muscles in the residual limb, allowing patients to control the prosthetic limb with proprioceptive feedback. A study of seven patients showed improved walking speed, obstacle navigation, and reduced pain. This innovation aims to restore natural movement and neural controllability in amputees.
