Shocking away the pain: TENS device tested for endometriosis flares
NCT ID NCT05348005
First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 2 times
Summary
This study tested whether a TENS unit, a small device that sends mild electrical pulses through the skin, can reduce pain during endometriosis flares. Forty women with surgically confirmed endometriosis tracked their pain for three months without the device, then for three months while using it during flares. The goal was to see if the TENS unit lowered daily pain scores and improved quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TENS unit (a device that sends mild electrical pulses through the skin to relieve pain)
- What this could lead to
- If it works, this could offer a drug-free, low-risk option for managing endometriosis flare pain at home.
- What could go wrong
- This is a small, completed crossover study with only 40 participants. Results may not apply to everyone, and the effect may be modest or no better than a placebo.
