Could a tiny zap replace painkillers for back pain in the ER?
NCT ID NCT07183176
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether a mild electrical device called TENS can safely relieve sudden low back pain in the emergency room. About 250 adults with acute back pain will receive either real TENS or a fake device for 30 minutes. The goal is to see if TENS reduces pain enough to avoid stronger drugs like morphine.
