High- and low-intensity expiratory muscle strength training in patients with severe obstructive sleep apnea syndrome using non-invasive mechanical ventilation: A double-blinded, randomized controlled trial

Obstructive sleep apnea syndrome (OSAS) is characterized by fatigue, noisy snoring, choking, frequent awakenings, and daytime sleepiness due to partial or complete airway obstruction by pharyngeal collapse during sleep.1 The most important factor in the pathophysiology of OSAS is dysfunction of the upper airway muscles, especially the submental muscles.1,2 However, respiratory muscle weakness is also thought to be related to disease severity.3,4
