What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether myofunctional therapy—simple exercises for the tongue, face, and breathing muscles—can improve sleep in children aged 6-12 with obstructive sleep apnea. Half of the 174 participants will do these exercises for 24 weeks with remote coaching, while the other half receives standard care. The goal is to see if the therapy reduces breathing pauses during sleep and improves symptoms and quality of life.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 174 people

The number the study aims to enrol. It can still change while the study runs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Children aged 6-12 years, with this age range, children start to have a greater ability to understand and follow instructions, making them more likely to comply and cooperate with the treatment procedures, and at the same time this age range remains a critical and modifiable developmental window when interventions can address underlying orofacial muscle and respiratory muscle dysfunctions and enhance the potential for long-term benefits. 2. Diagnosed with OSA based on clinical evaluation and polysomnography (oAHI ≥ 1/hour). The clinical evaluation will involve assessing the presence of habitual snoring, which is defined as snoring occurring 3 nights or more per week on average as reported by parents or caregivers, and any of the following features suggestive of SDB such as oral breathing, respiratory pauses, observed apnoeas, or increased work of breathing during sleep. Children with persistent OSA, documented by repeat PSG, can be included after receiving standard treatments (such as adenotonsillectomy treatment). 3. Informed consent from a parent or a legal guardian. Exclusion Criteria: * Genetic, syndromal, or metabolic disease * Congenital or acquired neuromuscular disease * Syndromal craniofacial abnormalities or previous craniofacial surgery * Severe developmental delay (developmental or functional age \<66% of chronological age) * Children with OSA who are indicated for and will receive other treatments such as adenotonsillectomy, positive airway pressure therapy or orthodontic treatment.
