Obstructive Sleep Apnea of Adult Clinical Trial
Official title:
Efficacy of Oropharyngeal Exercises for Patients With Residual Obstructive Sleep Apnea Using Mandibular Advancement Device
Oropharyngeal muscle training has emerged as a novel adjunctive treatment approach, involving training of the swallowing muscle group and tongue muscles to prevent tongue collapse, reduce tongue base volume during sleep, and strengthen muscle tension. Therefore, the objective is to assess changes in oropharyngeal muscle strength, ultrasonographic tongue morphology, severity of sleep related breathing interruptions, clinical symptoms, and correlations among these factors. Oropharyngeal muscle training for patients with residual OSA using MAD can significantly 1. increase muscle strength and endurance. 2. reduce the severity of sleep-related breathing interruptions. 3. decrease clinical symptoms. 4. improve tongue morphology.

Primary | Apnea-hypopnea -index | Assessed using Polysomnography (PSG). The average apnea and hypopnea events per hour, oxygen saturation index and the snoring index will be obtained during the sleep test(PSG). | Baseline to 12 weeks | |
Secondary | Tongue muscle strength | The maximal muscle strength of genioglossus muscles using The Iowa Oral Performance Instrument (IOPI) system, model 2.2 (Northwest, Co., LLC, Carnation, WA, USA) (kPa) | Baseline to 12 weeks | |
Secondary | Jaw strength | Jaw strength will be measured using a 'handheld' dynamometer (MicroFET?R2, Hoggan Scientific, USA). The data will be presented in kilogram-weight. The minimum score is 0 and a higher score indicates stronger in jaw strength. | Baseline to 12 weeks | |
Secondary | Tongue muscle endurance | The endurance of the genioglossus muscles using The Iowa Oral Performance Instrument (IOPI) system, model 2.2 (Northwest, Co., LLC, Carnation, WA, USA) (in seconds). | Baseline to 12 weeks | |
Secondary | Tongue Muscle Thickness | Sonography will be performed over the participant's neck region to assess the changes in tongue muscle thickness during normal breathing. | Baseline to 12 weeks |
