Summary

This study tests a small, non-invasive device that delivers mild electrical pulses to the ear to see if it can help people with chronic jaw pain (TMD). About 40 adults will use the device at home daily for a few weeks. The main goal is to see if people find it easy and comfortable to use, while also tracking changes in pain, mood, and thinking skills.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Transcutaneous Auricular Neurostimulation (tAN) device
What this could lead to: If this works, it could offer a drug-free, non-invasive option for people with chronic jaw pain who haven't found relief from standard treatments.
What could go wrong: This is a small, early feasibility study with only 40 people. It's designed to test if the device is acceptable, not yet to prove it works. The sham group may also show improvement, and results may not apply to everyone.
