About

The primary medical therapies for patients with Obstructive Sleep Apnea syndrome (OSA) require the use of medical devices on a nightly basis to help control breathing during sleep, which can be difficult for patients with mild-to-moderate disease. Because many patients use these therapies on a limited basis, or stop using them altogether, they continue to be at increased risk of the consequences of untreated OSA. Untreated and undertreated OSA compounds the risk of OSA consequences over time, particularly with increasing age and weight. Orofacial Myofunctional Therapy (OMT) takes a rehabilitative approach to OSA and is comprised of isotonic and isometric exercises that target the oral (e.g., tongue) and oropharyngeal (e.g., soft palate, lateral pharyngeal wall) to help restore normal breathing and airway patency at night while asleep. Should the study have positive findings, OMT could become an important alternative therapy for patients with mild-to-moderate disease because patients could utilize a therapy that improves their nighttime breathing through daytime exercises and without the need for a burdensome medical device.

Full description

The purpose of this study is to examine the effect of Orofacial Myofunctional Therapy in Veterans with mild-to-moderate sleep apnea. The main question to be answered is whether OMT improves measures of OSA severity, patient functional status, and OSA symptoms when compared to sham OMT.
