Could a simple nerve stimulation device ease phantom limb pain?
NCT ID NCT07448350
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether Transcutaneous Electrical Nerve Stimulation (TENS) can reduce phantom limb pain and improve walking in people with a leg amputation. Fifteen adults with above- or below-knee amputations will receive daily TENS sessions for four weeks. Researchers will measure changes in pain perception, balance, and gait.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous Electrical Nerve Stimulation (TENS)
- What this could lead to
- If it works, this could offer a non-drug way to ease phantom limb pain and improve walking for people with leg amputations.
- What could go wrong
- This is a very small, early study with only 15 people, so results may not apply widely. TENS may not reduce pain for everyone.
