What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This pilot study tests a digital program that uses facial recognition and guided exercises to strengthen throat muscles in people with mild-to-moderate obstructive sleep apnea. Sixty adults who cannot or will not use a CPAP machine will either receive the 3-month app-based therapy or join a waitlist. Researchers will measure changes in sleep quality, oxygen levels, and snoring, as well as how satisfied participants are with the program.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Digital-supported orofacial myofunctional therapy (app-based facial and tongue exercises)
What this could lead to
If it works, this could offer a non-invasive, drug-free way to reduce sleep apnea severity and improve sleep quality without a CPAP machine.
What could go wrong
This is a small pilot study with only 60 people, so results may not apply to everyone. The therapy requires daily exercise, and long-term benefits are not yet proven.
