Evaluation of a new simple treatment for positional sleep apnoea patients.

Obstructive sleep apnoea syndrome is a common clinical problem. Positional sleep apnoea syndrome, defined as having a supine apnoea-hypopnoea index of twice or more compared to the apnoea-hypopnoea index in the other positions, occurs in 56% of obstructive sleep apnoea patients. A limited number of studies focus on decreasing the severity of sleep apnoea by influencing sleep position.

Quantitative effects of trunk and head position on the apnea hypopnea index in obstructive sleep apnea.

Study Objectives: To test the hypothesis that head position, separately from trunk position, is an additionally important factor for the occurrence of apnea in obstructive sleep apnea (OSA) patients.

Design: Prospective cohort study.

Setting: St.
