First seen Jan 09, 2026 · Last updated Jun 15, 2026 · Updated 21 times
Summary
This study tests whether a nerve stimulation device placed on the ear (tAN) reduces pain by causing the body to release its own natural painkillers (opioids). Healthy adults aged 18-65 will receive either real or sham stimulation while also getting a drug that blocks opioids or a placebo. The goal is to understand how tAN works, not to treat a disease.
