About

The effect of expiratory muscle strength training (EMST) on sleep quality, disease severity, and respiratory muscle strength has been previously investigated in OSA syndrom. Only the effects of the high-intensity short-term EMST study in moderate OSAS patients were studied. High intensity and low intensity EMST has advantages and disadvantages.The study aims to compare the effects of high (60% MEP) and low (30% MEP) expiratory muscle strength training (EMST) on disease severity, sleep efficiency, snoring, fatigue severity and quality of life in severe OSAS patients.

Full description

Ahi Evren Chest Cardiovascular Surgery Training Research Hospital In sleep lab, polysomnography will be directed to the physiotherapist by the pulmonologist with severe OSAS patients. Patients will be divided into two groups by block randomization method. The study was planned as double-blind. Patients will not know what treatment they are receiving, the doctor does not know what treatment the patient is receiving, and technicians who take and analyze polysomnography will not know what treatment the patients are receiving.

Severe OSAS patients with MEP 30% (low intensity) to the first group, MEP 60% (high intensity) to the second group with expiratory muscle training device, 7 days / week, 25 breaths per day, 1 minute rest for 5 breaths will be run with the cycle. The training will take a total of 8 weeks. The follow-up of the patients will be done remotely by phone. MEP measurements will be repeated every 2 weeks in the hospital and the new training workload will be calculated.

---

32 participants in 2 patient groups

L-EMST

Experimental group

Description:

At 30% of the maximum expiratory pressure (MEP), 25 breaths, 7 days / week, a total of 8 weeks will be trained once a day with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 30% of the new measurement.

Treatment:

Other: Expiratory muscle trainig

H-EMST

Active Comparator group

Description:

In 60% of the maximum expiratory pressure (MEP), 25 breaths a day, 7 days / week, a total of 8 weeks will be trained with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 60% of the new measurement.
