Background and study aims
Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a condition where people experience repeated episodes of blocked breathing during sleep. This can lead to snoring, poor sleep quality, daytime sleepiness, and increased risk of heart problems. The most effective treatment is Continuous Positive Airway Pressure (CPAP), but not everyone sticks with it. This study aims to find out if using certain tools to measure muscle strength in the mouth and throat can help improve treatment for OSAHS.

Who can participate?
Adults aged 18 to 75 who have been diagnosed with moderate to severe OSAHS and have not received any prior treatment can participate. Healthy adults with good sleep habits and no complaints of snoring or daytime sleepiness can also participate as control subjects.

What does the study involve?
Participants will undergo various tests to measure the strength of their mouth and throat muscles using tools like the IOPI device, a digital manometer, and a digital spoon. They will also complete questionnaires about their sleep and muscle function. These tests will be done during a single visit to the hospital.

What are the possible benefits and risks of participating?
There are no expected side effects or complications from participating in this study. The tests are routine assessments commonly done in speech therapy and dysphagia units. Participants may benefit from gaining a better understanding of their condition and contributing to research that could improve treatment for OSAHS.

Where is the study run from?
Quirónsalud Hospital in Marbella and Hospital Campo de Gibraltar (Spain)

Health condition(s) or problem(s) studiedObstructive sleep apnea
InterventionParticipants are enrolled after signing informed consent and screened to confirm eligibility (OSAHS diagnosis for cases; good sleep hygiene and absence of symptoms for controls). The study consists of a single evaluation visit taking place during the same week as the patient’s sleep study. During this visit, participants complete the OMES questionnaire and undergo muscle tone assessments using the IOPI® manometer, Sandway® manometer, and a digital spoon. All tests are performed by a trained speech therapist and recorded for later blinded assessment. The total duration of observation is approximately 1 hour. There is no longitudinal follow-up; data collection is completed in a single session.
Intervention typeOther
Primary outcome measureOrofacial muscle function measured using the OMES questionnaire at baseline (single visit).
Secondary outcome measures1. Tongue and buccinator muscle strength measured using the IOPI® manometer at baseline (single visit). Measured in kilopascals (kps).
2. Tongue pressure measured using the Sandway® manometer at baseline (single visit). Measured in kilopascals (kps).
3. Tongue strength measured using a digital spoon at baseline (single visit). Measured in gr/cm².
4. Correlation between OMES score and values obtained by IOPI®, Sandway®, and digital spoon, analyzed at baseline (single visit)
