NCT05371509

Brief Summary

This research study is being done to determine whether the repetition and resistance from the daily use of the myofunctional therapy (MT) nozzle will improve obstructive sleep apnea and primary snoring.

Outcome Measures

Primary Outcomes (2)

  • Adherence to Therapy

    The was measured as the number of days subjects met their daily water consumption goal. Subjects were asked to hit their daily water consumption goal 5 days per week for 8 weeks.

    60 days

  • Change in Quality of Life

    Measured using the Calgary Sleep Apnea Quality of Life Index (SAQLI) questionnaire which assesses the quality of life in individuals with obstructive sleep apnea. It has a score between 1 and 7 on five different domains with total scores ranging from 7 to 42, with higher scores indicating a worse quality of life.

    Baseline, Day 60

Secondary Outcomes (5)

  • Change in Apnea Hypopnea Index (AHI)

    Baseline, Day 60

  • Change in Myofunction Assessment

    Baseline, Day 60

  • Change in Oxygen Saturation (SpO2)

    Baseline; 60 Days

  • Change in Snoring Intensity

    Baseline; Day 60

  • Change in Snoring Frequency

    Baseline; Day 60

Study Arms (2)

Myofunctional therapy (MT) nozzle

EXPERIMENTAL

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

Placebo nozzle

PLACEBO COMPARATOR

Subjects diagnosed with mild to moderate obstructive sleep apnea will receive a water bottle with a placebo nozzle to use daily

Other: Placebo nozzle

Interventions

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.

Myofunctional therapy (MT) nozzle

The placebo bottle nozzle will look similar to the MT nozzle; but is not expected to function the same as the MT nozzle.

Placebo nozzle

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of mild to moderate obstructive sleep apnea with Apnea Hypopnea Index 5-29 events/hour confirmed within last 2 years with an in-lab diagnostic polysomnography or home sleep apnea test.

  • Previous upper airway surgeries significantly modifying upper airway anatomy.
  • Known congenital or acquired diseases significantly affecting upper airway anatomy.
  • BMI \>40 kg/m\^2.
  • Currently treating OSA with hypoglossal nerve stimulator.
