Brief Summary

Background: Upper airway muscle weakness plays an important role in the genesis of obstructive sleep apnea (OSA). Oropharyngeal exercises are derived from speech therapy consisting of isometric and isotonic exercises directed to tongue, soft palate and lateral pharyngeal wall. We hypothesized that oropharyngeal exercises will attenuate OSA severity. We will include 30 moderate OSA patients (apnea-hypopnea index (AHI), between 15 and 30 events/hour) that will randomize to 3 months of general measurements and daily nasal lavage (n=15, control) or daily oropharyngeal exercises (\~30 min) plus nasal lavage (n=16). Full polysomnography, anthropometric measurements, questionnaires derived from Berlin, Epworth and Pittsburgh evaluating quantitatively (range) snoring frequency (0-4) and intensity (1-3), daytime sleepiness (0-24) and sleep quality (0-21), respectively will be performed at baseline and study end.
