Ear-Zap device may cut opioid use after spinal surgery
NCT ID NCT07330973
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a non-invasive device that gently stimulates a nerve in the ear to see if it can reduce pain and the need for strong painkillers after complex spinal surgery. About 98 adults having major back surgery will be randomly assigned to receive either the real stimulation or a sham (fake) version. The goal is to find a safer, drug-free way to manage acute post-surgical pain.
