Cervical Collar for Patients With Moderate Obstructive Sleep Apnea

Obstructive Sleep Apnea Clinical Trial

Official title: Evaluation of Treatment Effect of Cervical Collar in Moderate Obstructive Sleep Apnea

Status Completed

Clinical Trial Summary

This study evaluates treatment effect of Cervical Collar (CC) in moderate obstructive sleep apnea.The investigators believe that stabilization of the neck by using a CC during sleep helps sustain airway patency. This would mean preventing collapse of airways during sleep.

The study is a randomized, open, parallel-group intervention study. The two treatment groups are:

A. Patients with moderate OSA are treated with lifestyle advice (n = 50) B. Patients with moderate OSA are treated with CC and lifestyle advice (n = 50).

Clinical Trial Description

Moderate and severe obstructive sleep apnea (OSA) is strongly associated with cardiovascular diseases, diabetes and also with occupational and traffic accidents due to fatigue and daytime sleepiness. Treatment of moderate OSA is usually by a mandibular advancement device (MAD) and in sometimes even Continuous Positive Airway Pressure (CPAP). MAD and CPAP treatment effectiveness is impeded by limited compliance with long term treatment. Knowledge about mechanical barriers in upper respiratory tract has triggered interest in finding a new treatment method that may prevent collapse of airways during sleep. The investigators believe that stabilization of the neck by using a cervical collar (CC) during sleep helps sustain airway patency. This would mean improved oxygen saturation in the blood and a reduction of daytime fatigue in patients with OSA. ;
