Study objective: To compare the severity of sleep apneic events occurring in the supine posture vs the severity of sleep apneic events occurring in the lateral posture in patients with severe obstructive sleep apnea (OSA).
Study objectives: The primary aim of this study was to determine the prevalence of positional obstructive sleep apnea using a functional definition. Positional sleep apnea was defined as a total apnea-hypopnea index (AHI) > 5 with a > 50% reduction in the AHI between the supine and non-supine postures, and an AHI that normalizes (AHI < 5) in the non-supine posture. A secondary aim was to determine if positional sleep apnea can be diagnosed accurately during a split-night study.
CHEST - 2005
To compare anthropomorphic, nocturnal polysomnographic (PSG), and multiple sleep latency test (MSLT) data between positional (PP) and nonpositional (NPP) obstructive sleep apnea (OSA) patients.
Background: Approximately half of obstructive sleep apnea (OSA) patients are positional (i.e., the majority of their breathing abnormalities during sleep appear in the supine posture). Little information exists as to whether avoiding the supine posture during sleep (positional therapy) is a valuable form of therapy for these patients. Aim: To assess the use of positional therapy (by the tennis ball technique [TBT]) during a 6 month period in 78 consecutive positional OSA patients
The Laryngoscope: 2006
A 42-year-old man, complained about loud snoring. The EES was 2 and BMI was 26.3. His PSG revealed an AHI = 36.2. The supine and lateral AHI were 102.1 and 3.1, respectively. He expressed interest in using the tennis ball technique to avoid the supine posture during sleep. Sleep Medicine 6 (2005)
Objectives:To examine the reliability of a diagnosis of positional obstructive sleep apnea (OSA), with an apnea hypopnea index (AHI) for lateral sleep less than half the supine AHI (S-AHI) and less than 15 per hour, in patients using positional therapy for a full night.

Background: Obstructive sleep apnea (OSA) is a common chronic disorder that often requires lifelong care. Available practice parameters provide evidence-based recommendations for addressing aspects of care. Objective: This guideline is designed to assist primary care providers as well as sleep medicine specialists, surgeons, and dentists who care for patients with OSA by providing a comprehensive strategy for the evaluation, management and long-term care of adult patients with OSA.
Journal of Clinical Sleep Medicine, Vol.5, No. 3, 2009
Objectives: The aim of this study was to compare the relative efficacy of continuous positive airway pressure (CPAP) and positional treatment in the management of positional obstructive sleep apnea (OSA), using objective outcome measures. Design: A prospective, randomized, single blind crossover comparison of CPAP and positional treatment for 2 weeks each.
