Zapping away nerve pain: 40 kHz currents tested in spinal injury patients
NCT ID NCT07359677
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a mild electrical stimulation (40 kHz) applied through the skin can safely reduce nerve pain in people with spinal cord injury. Thirty adults with paraplegia and chronic nerve pain received either real or placebo stimulation alongside their usual treatment. The goal was to see if the device could lower pain scores over several weeks.
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 stimulation with 40 kHz alternating currents
- What this could lead to
- If it works, this could offer a non-drug option to ease nerve pain after spinal cord injury.
- What could go wrong
- This is a very small pilot study with only 30 people, so results may not apply widely. The treatment is still experimental and may not reduce pain better than placebo.
