Bionic leg feedback: can a neuroprosthesis bring back sensation for amputees?
NCT ID NCT04658693
First seen Mar 17, 2026 · Last updated Jun 23, 2026 · Updated 11 times
Summary
This study tests a sensory neuroprosthesis—implanted electrodes that send small electrical currents to remaining nerves—to restore sensation of a missing lower limb in people with diabetic peripheral neuropathy and amputation. The 15 participants will also have the option of muscle recording electrodes to help control a robotic prosthetic leg. Researchers will measure how well the device works and its effect on walking stability.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Sensory neuroprosthesis (implanted stimulating and recording electrodes)
What this could lead to
If it works, this could help people with limb loss regain sensation and improve walking stability.
What could go wrong
This is a very small early study with only 15 participants, so results may not apply widely. Implant surgery carries risks like infection or nerve damage.
As listed by the trial registrant
The condition terms exactly as the trial's registrant entered them.
