Validation of the OMES questionnaire compared to objective measurement of oropharyngeal muscle tone using the IOPI manometer, Sandway manometer, and digital spoon
Obstructive sleep apnea
Participants 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.
