“…Although earlier studies reported the AHI as negative predictor for POSA [12,13,[20][21][22], this was not found in the current study. Additionally, neck circumference appeared no predictor in current analysis, whereas contrasting results were published by Mador et al and Teerapraipuk et al [12,22]. Although five univariate variables reached a significance level below 0.2 in this study, only two were significant in multivariable analysis.…”

“…1,2 This proportion in even higher in Asian patients. [3][4][5] Compared to patients without position dependence, these patients tend to be less obese, younger, with better sleep quality and less daytime sleepiness. 6 It has been argued that since most obstructive sleep apnea (OSA) patients have mild to moderate severity and since position dependence is most prevalent in these categories, the great majority of patients with sleep-disordered breathing demonstrate this phenotype.…”

“…12 The prevalence of POSA is thought to be higher in Asian populations. 13,14 Most but not all PP still snore when sleeping in the lateral posture, but their sleep is interrupted with only a few apneas or hypopneas or not at all, and they consequently achieve a better sleep quality.…”

Study Objectives:In approximately 56% to 75% of patients with obstructive sleep apnea (OSA), the frequency and duration of apneas are influenced by body position. This is referred to as position-dependent OSA or POSA. Patients with POSA can be treated with a small device attached to either the neck or chest. These devices-a new generation of devices for positional therapy (PT)-provide a subtle vibrating stimulus that prevents patients adopting the supine position. The objectives of this study were to determine whether PT is effective in improving sleep study variables and sleepiness, and to assess compliance. Methods: A systematic review and meta-analysis. Results: Three prospective cohort studies and four randomized controlled trials were included in this review. Combined data for studies reporting on the effect of PT show that there was a mean difference of 11.3 events/h (54% reduction) in apnea-hypopnea index and 33.6% (84% reduction) in percentage total sleeping time in the supine position. The standardized mean difference for both parameters demonstrated a large magnitude of effect (> 0.8 in both cases). Conclusions: There is strong evidence that the new generation of devices for PT are effective in reducing the apnea-hypopnea index during short-term follow-up. These devices are simple-to-use for patients and clinicians and are reversible. Under study conditions with short-term follow-up, compliance is high; however, long-term compliance cannot be assessed because of lack of reliable data. Additional long-term, high-quality studies are needed to confirm the role of PT as a single or as a combination treatment modality for OSA patients and to assess long-term compliance.

I NTRO DUCTI O NIn approximately 56% to 75% of patients with obstructive sleep apnea (OSA), the frequency and duration of apneas are influenced by body position.1-5 Various definitions of positiondependent obstructive sleep apnea (POSA) have been applied in literature, but the most common classification system and definition marks a distinction between two groups of patients: positional patients (PP) 6 and nonpositional patients (NPP). 3,4,7In PP, desaturations, cyclic variations in heart rate, loud snoring, and apneas and hypopneas appear almost exclusively in the supine position. 8 Cartwright first described the arbitrary cutoff point of a difference of 50% or more in apnea index between supine and nonsupine positions. In the medical literature many have applied modified versions of Cartwright's criteria. In 1998, Marklund et al. defined supine-dependent sleep apnea as a supine apnea-hypopnea index (AHI) ≥ 10 events/h, together with a lateral AHI < 10 ev...
