Abstract

PurposeResearch during the past 10–20 years shows that positional therapy PT has a significant influence on the apnea–hypopnea index.
These studies are predominantly performed as case series on a comparably small number of patients.
Still, results have not found their way into the daily diagnostic and treatment routine.
An average of 56 % of patients with obstructive sleep apnea OSA have position-dependent OSA POSA, commonly defined as a difference of 50 % or more in apnea index between supine and non-supine positions.
A great deal could be gained in treating patients with POSA with PT.
The aim of this paper was to perform a thorough review of the literature on positional sleep apnea and its therapy.

MethodsA broad search strategy was run electronically in the MEDLINE and EMBASE databases using synonyms for position and sleep apnea.

ResultsSixteen studies were found which examined the effect of PT on OSA.
In this literature review, we discuss the various techniques, results, and compliance rates.

ConclusionLong-term compliance for PT remains an issue, and although remarkable results have been shown using innovative treatment concepts for PT, there is room for both technical improvement of the devices and for further research.
