Magnetic beads in the leg could make bionic limbs respond better

NCT ID NCT07195461

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early study tests whether small magnetic beads implanted in the leg can help people with below-knee amputations control a bionic prosthetic more naturally. Up to 5 participants will have the beads placed during amputation or revision surgery. Researchers will measure walking speed and obstacle course performance to see if the magnetic tracking system improves control compared to standard prosthetic controllers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Magnetic Bead Tracking System (implanted magnetic beads and external tracking device)
What this could lead to
If successful, this could lead to more natural and faster walking for people with below-knee amputations using bionic prosthetics.
What could go wrong
This is a very early feasibility study with only 3-5 participants. The technology may not work as hoped, and there are risks from surgery and the implanted beads.
