Can a gentle zap under the chin help you swallow better?
NCT ID NCT02170506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a mild electrical stimulation applied under the chin (transcutaneous electrical stimulation) can change how the brain controls swallowing. Ten healthy adults without swallowing problems took part. The goal was to see if this non-invasive technique could affect brain signals related to swallowing, which might help people who have trouble swallowing after a stroke.
