About

The effects of orofarangeal exercises (OE) and inspiratory muscle training (IMT) on sleep quality, disease severity, and airway muscle tone have been investigated in several studies. IMT and OE exercise modalities for patients and practitioners have advantages and disadvantages. It is recommended to compare exercise modalities in the studies. Whether OE or IMT exercise type is more effective on disease severity, sleep quality and snoring has not been investigated. The aim of this study was to compare the effectiveness of inspiratory muscle training and oropharyngeal exercises in patients with OSAS in terms of disease severity, snoring, daytime sleepiness, respiratory muscle strength and sleep quality.

41 participants in 3 patient groups

Oropharyngeal exercises

Experimental group

Description:

Oropharyngeal exercises include soft palate, tongue and facial muscle exercises as well as stomatognathic function exercises. Training sessions were held once a day, 5 days a week for 12 weeks under the supervision of a mirror.

Treatment:

Other: oropharyngeal muscles strengthening exercise

Inspiratory muscle training

Experimental group

Description:

The inspiratory muscle training group was administered for 12 weeks starting from 30% of maximal oral pressure, 7 days a week, 15 minutes twice a day. Patients came to the control once a week, mouth pressures were measured and training pressure was adjusted in 30% of the new value.

Treatment:

Other: respiratory muscle strengthening exercise

Control

No Intervention group

Description:

This group was only monitorized without any rehabilitation intervention.
