Myofunctional Therapy for Obstructive Sleep Apnea

University of Minnesota30 enrolled

Overview

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.

Outcomes

Primary Outcomes

MFT treatment fidelity

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.

Time frame: Day 90
