NCT ID NCT05490134
First seen Jan 09, 2026 · Last updated May 14, 2026 · Updated 16 times
Summary
This study tests if a device that gently stimulates nerves in the ear (tAN) relieves pain by causing the body to release its own natural painkillers (endogenous opioids). 136 healthy adults will receive either real or sham stimulation, plus an IV that either blocks opioids or is a placebo. The goal is to understand how the device works, not to treat a disease.
