Could a simple ear device ease fibromyalgia pain and fatigue?
NCT ID NCT07682090
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study tests whether a non-invasive device that stimulates a nerve in the ear can help people with fibromyalgia. Participants use the device for 30 minutes daily over four weeks. The goal is to see if it reduces pain, fatigue, and other symptoms by calming the body's stress response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcutaneous vagus nerve stimulation (tVNS) device
- What this could lead to
- If effective, this could offer a drug-free, at-home option to reduce pain, fatigue, and other fibromyalgia symptoms.
- What could go wrong
- This is a small, early-stage trial. The sham control may show no difference, and benefits may not last beyond the four-week treatment period.
