Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in Apnea Hypopnea Index (AHI; measure of sleep apnea disease severity)

    Compare the change in AHI between OMT and inactive OMT groups over the follow-up time points. Higher AHI scores indicate increase sleep apnea disease severity.

    3 months and 6 months

Secondary Outcomes (3)

  • Change in Functional Outcomes of Sleep Questionnaire (FOSQ; measure of daytime functioning)

    3 months and 6 months

  • Change in Epworth Sleepiness Score (ESS; measure of sleepiness)

    3 months and 6 months

  • Change in Pittsburgh Sleep Quality Index (PSQI; measure of sleep quality)

    3 months and 6 months

Study Arms (2)

Active Myofunctional Therapy

ACTIVE COMPARATOR

Active Myofunctional Therapy is comprised of five 30-minute weekly sessions for 4 weeks.

Behavioral: OMT Exercises

Inactive Myofunctional Therapy

SHAM COMPARATOR

Sham MT will be comprised of recommendations for five 30-minute nasal breathing exercises each week, use of nasal lavage with application of 10ml of saline in each nostril two times per day.

Behavioral: Nasal Breathing ExercisesOther: Use of Nasal Lavage
