A Comparative Study of Effects of Oropharyngeal Exercises and Continuous Positive Airway Pressure (CPAP) on Parameters of Sleep on Moderate Obstructive Sleep Apnea Syndrome (OSAS) Patients

Author: Kaniethapriya A.S, Ganesh Prasad S.

Category: Physiology


Background: Obstructive sleep apnea syndrome is a highly prevalent serious chronic illness characterized by repeated, complete or partial obstruction of the upper airways during sleep, mainly at the level of the oropharynx. Upper airway dilator muscles are important for the maintenance of pharyngeal patency.


1. To assess the effects of Oropharyngeal exercises and CPAP on moderate OSAS patients

2. To compare effects of oropharyngeal exercises and CPAP therapy on moderate OSAS patients. Materials & Methods: Recently diagnosed 20 Moderate OSAS patients of age group 25-60 years were included in the study. Group A consisted of 10 patients who practiced only oropharyngeal exercises (Tongue, Soft palate and Lateral pharyngeal wall) regularly 30 minutes a day for 3 months. Group B consisted of 10 patients who were on only CPAP therapy for 3 months.

Results: The results observed in Exercised and CPAP group were as follows: A significant decrease in day time sleepiness score (p<0.005, p<0.001), sleep quality index (p<0.008, p< 0.001), apnea- hypopnea index (p<0.001, p< 0.001), oxygen desaturation index (p<0.002, p<0.001), number of desaturations (p< 0.013, p<0.002), snoring events (p<0.004, p<0.039) was observed.

Conclusion: Though regular practice of Oropharngeal exercises/CPAP significantly reduced the severity in moderate OSAS patients, the effects observed with CPAP therapy had better results on comparison.
