Shocking new hope: brain zaps may restore swallowing after stroke
NCT ID NCT07212634
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a safe, non-invasive brain stimulation technique called tDCS to help people who have trouble swallowing after a stroke. About 76 adults who had a stroke 1 to 6 months ago will receive either real or fake stimulation over the cerebellum. Researchers will measure changes in swallowing safety and muscle activity to see if this approach can ease symptoms and improve quality of life.
