An interventional study of Exercise in Obstructive Sleep Apnea (OSA), Snoring and Sleep Quality, sponsored by Case Western Reserve University. Active, not recruiting at 1 site in United States. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-10-27.
Sponsored by Case Western Reserve University · Not applicable, Interventional, and Treatment
This is a study to test if performing airway exercises to improve snoring and sleep apnea using a mobile phone app is better than using a hardcopy guide.
Outcomes will be measured using tone analysis, snoring recording apps, and oximeters.
2,240 studies on the registry are indexed under Sleep Apnea, Obstructive; 475 are open to participants now.
This study's planned enrollment of 34 is below the median of 52 across 1,472 interventional studies indexed under Sleep Apnea, Obstructive.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

The mouth exercises are guided and tracked by a phone application.
Other: Exercise
The exercise and tracking is done using paper forms.
Other: Exercise
Mouth, tongue, and throat exercise to strengthen the airway, reducing its collapsibility.
Also known as: Myofunctional Mouth Exercise
Belun Ring Oxygen Saturation
Oximeter with pulse rate registration. The oximeter will provide the average level of oxygen saturation in the blood, provided in a percentage outcome. .
Time frame: baseline and then monthly for 3 months.
Belun Ring lowest Oxygen Saturation Level
Oximeter with pulse rate registration. The oximeter will provide the lowest level of oxygen saturation recorded as a percentage.
Time frame: baseline and then monthly for 3 months.
Belun Ring Oxygen Saturation under 70%
Oximeter with pulse rate registration. The oximeter will provide the percentage of sleep that was under 70% SpO2.
Time frame: baseline and then monthly for 3 months.
Belun Ring AHI
Oximeter with pulse rate registration. The oximeter provides the Apnea/Hypopnea Index which is the number of apneic events per hour of sleep.
Time frame: baseline and then monthly for 3 months.
Belun Ring Pulse Rate
Oximeter with pulse rate registration. The oximeter provides the pulse rate as the average beats per minute with standard deviation, and range.
Time frame: baseline and then monthly for 3 months.
SnoreLab app
A mobile phone app that records snoring when present, and categorizes into amount and level. Possible outcomes are: none, mild, moderate, severe, and epic.
Time frame: baseline and monthly for 3 months.
Tongue Elevation strength
The Iowa Oral Performance Instrument, is a validated intraoral device that measures tongue elevation strength in kPa.
Time frame: baseline and monthly for 3 months.
Tongue Protrusion strength
The Iowa Oral Performance Instrument is a validated intraoral device that measures tongue protrusion strength in kPa.
Time frame: baseline and monthly for 3 months.
Buccinator strength
The Iowa Oral Performance Instrument is a validated intraoral device that measure the buccinator muscle strength in kPa.
Time frame: baseline and monthly for 3 months.
STOP-Bang Questionnaire
STOP-Bang is a validated tool that determines if the subject is at no, low, moderate, or severe risk of sleep-apnea. It provides an objective score that ranges from 0 to 8.
Time frame: baseline and monthly for 3 months.
Nasal Obstruction Assessment (NOSE) Questionnaire Score
NOSE is a validated tool that determines the level of difficulty that the subject experienced in breathing through their nose in the past 3 months. The questionnaire provides an objective score stating the risk level that ranges from 0 to 100 with lower scores indicating less nasal blockage and higher scores indicating worse nasal blockage.
Time frame: baseline and monthly for 3 months.
PROMIS Sleep Disturbance 8b Short Form Questionnaire
Assesses self-reported perceptions of sleep quality, sleep depth, and restoration associated with sleep. Each question usually has five response options ranging in value from one to five. Values are summed to generate a raw score that is then translated to a t-score with a mean of 50, std of 10.
Time frame: baseline and monthly for 3 months.
Epworth Daytime Sleepiness Questionnaire
This is a validated tool that measures a person's daytime sleepiness and is commonly used to help diagnose sleep disorders. Eight prompts with each response scored from 0-3. Higher scores indicates greater sleepiness. It provides an objective score that can range from 0 to 24.
Time frame: baseline and monthly for 3 months.
PROMIS Sleep Impairment 8a Short Form Questionnaire
Assesses self-reported perceptions of alertness, sleepiness, and tiredness during usual waking hours, and the perceived functional impairments during wakefulness associated with sleep problems or impaired alertness. Each question usually has five response options ranging in value from one to five. Values are summed to generate a raw score which is then translated to a t-score with a mean of 50, std of 10.
Time frame: baseline and monthly for 3 months.
