Plain English Summary
Background and study aims
Obstructive sleep apnea is a potentially serious sleep disorder. It causes breathing to repeatedly stop and start during sleep.
There are several types of sleep apnea, but the most common is obstructive sleep apnea. This type of apnea occurs when your throat muscles intermittently relax and block your airway during sleep.
The classic treatment of this disease is based on dietary measures, losing weight, and exercise, and the use of a continuous positive airway pressure (CPAP) machine (a device that reduces collapsibility of the upper airway by emitting a flow of air). Other options are upper airway surgery treating the obstacle of the airway or correcting the muscles that do not perform their function properly, and mandibular advancement devices (MAD), which push the tongue forward to avoid it falling backward and collapsing the airway.
Myofunctional therapy (MT) has become one of the newest treatments for sleep-disordered breathing. MT is based on daily exercises of the throat muscles in an attempt to strength them and facilitate opening of the airway.
Who can participate?
Patients diagnose with sleep apnea and aged between 18 – 75 years.
What does the study involve?
Participants will be randomly allocated to either use of the ‘Airway gym’ smartphone app or treatment as usual for three months. The airway gym app provides instructions on how to perform exercises to strengthen the throat muscles and also reminds participants to perform the exercises for 20 minutes per day. Each month participants will be assessed at the clinic.
What are the possible benefits and risks of participating?
Benefits: Curing sleep apnea syndrome.
There are no signficant risks for participants.
Where is the study run from?
Hospital Quironsalud Marbella (Spain)

Study information
Scientific title
Effects of myofunctional therapy with an m-health application airway gym in severe apnea/hypopnea sleep obstructive syndrome. A randomized multicentre control trial
Acronym
MTASSAOS
Study hypothesis
The periodical use of the app 'Airway Gym' designed to perform and increase adherence in Myofunctional therapy (MT), improve obstructive sleep apnea/hypopnea syndrome ( OSAHS) in patients with severe disease (AHI>30) increasing the tone of the upper airway muscles.

Condition
Severe sleep apnea/hypopnea syndrome
Intervention
Experimental group: Myofunctional exercises based on a mHealth App AirwayGym daily performed during 3 months 20 minutes a day.
Control group: No intervention.
Patients will be randomized consecutively.
Intervention type
Behavioural
Primary outcome measure
At baseline and 3 months:
1. Severity of apnea measured using The Apnea–Hypopnea Index
2. Saturation O2 and Nadir O2 measured using oximeter
3. Tongue strength measured using the Iowa Oral Performance Instrument (IOPI)
Secondary outcome measures
Measured each month for 3 months:
1. Sleep quality measured using Pittsburgh Sleep Quality Index (PSQI)
2. Sleepiness measured using Epworth sleepiness scale
3. BMI (kg/m²)
4. Neck and waist circumference (cm)
