Adherence

Positional therapy (PT) significantly reduces the Apnea-Hypopnea Index (AHI) in patients with position-dependent obstructive sleep apnea (POSA), though it is less effective than CPAP at normalizing AHI, while offering superior long-term compliance.

If you have sleep apnea that gets worse when you sleep on your back, positional therapy is a valid, non-invasive treatment option. It works by keeping you off your back, which significantly reduces breathing interruptions (AHI). While it may not be as powerful as CPAP at completely eliminating apneas, it is often easier to stick with long-term because it is less intrusive. Devices range from simple tennis ball techniques to modern vibrating neck devices. The key is finding a method you can tolerate nightly.

ModerateQualifiesMEDIUM confidence
All studies report a positive effect of PT on the AHI. PT compliance is better than CPAP compliance, but the latter is a more effective treatment.

Based on case series and small randomized trials; the review notes a lack of large-scale clinical trials.
