Active Comparator: Active Myofunctional Therapy
Active Myofunctional Therapy is comprised of five 30-minute weekly sessions for 4 weeks.
|
Behavioral: OMT Exercises
Oral and oropharyngeal exercises |
Sham Comparator: Inactive Myofunctional Therapy
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.

- Change in Apnea Hypopnea Index (AHI; measure of sleep apnea disease severity) [ Time Frame: 3 months and 6 months ]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.
- Change in Functional Outcomes of Sleep Questionnaire (FOSQ; measure of daytime functioning) [ Time Frame: 3 months and 6 months ]Compare the change in FOSQ between OMT and inactive OMT groups over the follow-up time points. Higher FOSQ scores indicate improved levels of daytime functioning.
- Change in Epworth Sleepiness Score (ESS; measure of sleepiness) [ Time Frame: 3 months and 6 months ]Change in ESS between OMT and inactive OMT groups over the follow-up time points. Higher ESS scores indicate higher sleepiness levels.
- Change in Pittsburgh Sleep Quality Index (PSQI; measure of sleep quality) [ Time Frame: 3 months and 6 months ]Change in PSQI between OMT and inactive OMT groups over the follow-up time points. Higher PSQI scores indicate worse sleep quality.
