Brief summary
The purpose of this study is to explore a new way to examine the function of the muscles using a technique called high-resolution manometry. The study will enroll 30 adults with OSA, all of whom will use the myofunctional therapy (MFT) devices for 3 months. High-resolution manometry will be used to measure the amount of pressure generated by the muscles of the throat when drinking water or breathing air, both with and without the MFT devices, and before and after the MFT intervention. If successful, this method can help us understand why sleep improves after MFT.
Interventions
PROCEDUREMyofunctional Therapy
The intervention consists of 90 days of MFT (5-6 days/week) along with completing daily logs. MFT will include high-intensity swallowing exercises and respiratory muscle strength training.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| MFT treatment fidelity | Day 90 | Treatment fidelity of two common MFTs (high-intensity swallowing exercises, respiratory muscle strength training) in individuals with OSA. Treatment fidelity will be determined via measuring the percent of sessions completed relative to the targeted number of sessions. |
| Pressure generation in posterior upper airway musculature | Day 90 | Comparison of pressure generation in posterior upper airway musculature before and after MFT intervention as assessed with HRM |
