Digital-supported Orofacial Myofunctional Therapy in OSA
Digital-supported Orofacial Myofunctional Therapy in Subjects With Obstructive Sleep Apnoea: A Pilot Randomised Control Trial
Hong Kong Metropolitan University
60 participants
Jan 5, 2026
INTERVENTIONAL
Conditions
Summary
This pilot study explores the feasibility, acceptability, and preliminary effectiveness of Digital-supported Orofacial Myofunctional Therapy (d-MFT), an innovative program combining facial recognition technology with evidence-based orofacial exercises for individuals with mild to moderate obstructive sleep apnoea (OSA). The d-MFT program aims to strengthen oropharyngeal muscles, improve airway function, and reduce OSA severity. Participants receiving 3-month d-MFT (n=30) are expected to demonstrate greater improvements in OSA severity, sleep-related symptoms, and quality of life compared to those in the waitlist control group (n=30). Feasibility and acceptability will be evaluated through outcome-based questionnaires and semi-structured interviews to explore participants' experiences, satisfaction, and perceived barriers to adherence.
