Bionic breakthrough: new surgery lets amputees 'Feel' their prosthetic foot
NCT ID NCT03913273
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed trial tested a new surgical procedure called an agonist-antagonist myoneural interface (AMI) in 14 people with below-knee amputations. The surgery connects muscle pairs in the residual limb to allow better communication with a bionic prosthetic. The goal was to improve control and provide a sense of joint position and movement, making the prosthetic feel more like a natural limb.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Agonist-antagonist myoneural interface (AMI) surgical procedure
What this could lead to
If successful, this could lead to bionic legs that feel more natural and are easier to control, improving mobility and quality of life for people with below-knee amputations.
What could go wrong
This was a small, early-stage trial with only 14 participants. The results may not apply to all amputees, and the procedure requires specialized surgery. Long-term benefits and risks are still unknown.
