AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with mild to moderate obstructive sleep apnoea who cannot tolerate or do not want CPAP or an oral appliance. It tests a 3-month digital program of mouth and face exercises.
- Age
- 18 years and above
- Sex
- All sexes
- Disease stage
- Mild to moderate obstructive sleep apnoea: Apnoea-Hypopnea Index of 5-30 events per hour. Body Mass Index less than 30 kg/m2.
- Earlier treatment
- People must have a reason for Continuous Positive Airway Pressure (CPAP) or oral appliance treatment, but be unable to tolerate it or decline it. People who had prior oral, throat or jaw-face surgery for sleep apnoea cannot join.
Main reasons for not taking part
- Blocked nose or nasal disease that blocks breathing
- Unstable mental health issues
- History of stroke
- Unstable long-term lung, heart or nerve conditions

About the trial
What the trial wants to find out
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.
Read full original descriptionShow less
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.
The 2 groups in the trial
- Waitlist Control GroupNo study treatment, for comparison
The waitlist control group will not receive any intervention within the study period
- d-MFT Intervention GroupTreatment being tested
The d-MFT intervention group will participate in a 3-month digital-support Myofunctional Therapy program. This innovative program is designed to ensure proper exercise performance, enhance adherence, and provide real-time feedback to patients.
