Arm | Intervention/treatment |
---|---|
Experimental: Myofunctional therapy (MT) nozzle
Subjects diagnosed with mild to moderate obstructive sleep apnea will receive a water bottle with a myofunctional therapy (MT) nozzle to use daily
|
Device: Myofunctional therapy (MT) nozzle
Water bottle nozzle designed to allow the user to repeatedly perform the tongue suction, tongue press, and swallow exercise movements while also providing targeted resistance to train and improve tongue, soft palate, and pharyngeal muscle strength and endurance. |
Placebo Comparator: Placebo nozzle
Subjects diagnosed with mild to moderate obstructive sleep apnea will receive a water bottle with a placebo nozzle to use daily
|
Other: Placebo nozzle
The placebo bottle nozzle will look similar to the MT nozzle; but is not expected to function the same as the MT nozzle. |
- Adherence to Therapy [ Time Frame: 60 days ]Patient will use nozzle consistently and as instructed while regularly reporting results
- Change in quality of life [ Time Frame: Baseline, Day 60 ]Measured using the Calgary Sleep Apnea Quality of Life Index (SAQLI) questionnaire which has a score between 1 and 7 on five different domains. Higher mean scores are suggestive of worse quality of life.
- Change in Apnea Hypopnea Index [ Time Frame: Baseline, Day 60 ]Apnea Hypopnea Index measured by WatchPAT One device
- Myofunction Assessment [ Time Frame: Baseline, Day 60 ]Myofunction assessment including tongue strength and endurance measurements by IOPI device. This measurement is reported in kPa and seconds. A higher value on these measurements is suggestive of higher tongue strength and endurance.
