Positional Therapy for Positional Obstructive Sleep Apnea

Positional therapy appears to be an attractive strategy for many patients with positional obstructive sleep apnea (OSA). However, under the American Academy of Sleep Medicine OSA guidelines, positional therapy is considered as only an alternative therapy, because previous research has demonstrated poor treatment tolerance and adherence. Recent technological advances have renewed interest in positional therapy, with the invention of new sophisticated vibratory positional therapy devices. These devices have shown great promise with efficacy, markedly improved patient tolerance, and long-term adherence. We review the literature on positional therapy and explore the most current evidence on the new positional therapy devices.
