A recap and follow-up on "Make Me Bionic", one of the eleven topics covered in our 2023 Future of Health Report.
Prosthetic Control:
- Researchers from MIT and Brigham and Women’s Hospital are making progress on bionic prosthetics that can be controlled by an amputee’s own nervous system. The surgical procedure known as the agonist-antagonist myoneural interface (AMI), reconnects muscles in the residual limb, enabling patients to receive “proprioceptive” feedback allowing them to sense the position of their prosthetic limb in physical space.
- In a recent study, the team evaluated the performance of two groups of seven people using the same type of bionic limb. One group had undergone AMI surgery, while the other had traditional below-the-knee amputations. Those with the AMI surgery demonstrated a more natural walking pattern, climbed stairs and maneuvered through obstacles faster, similar to someone without an amputation. This is the first study to show such success with a prosthetic under full neural modulation. The surgery can also be performed on people with arm amputations, and so far, around 60 patients have received it.
