Tongue zaps during sleep test could improve apnea therapy
NCT ID NCT03589846
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how stimulating two specific tongue muscles (palatoglossus and genioglossus) affects airway size during a sleep endoscopy procedure. Researchers will measure changes in the airway with and without stimulation in 60 adults with obstructive sleep apnea who cannot use CPAP. The goal is to gather basic data to improve nerve stimulation treatments for sleep apnea.
