Obstructive sleep apnea (OSA) is a treatable global health concern with increasing prevalence, driven by the obesity epidemic and the aging population. Unfortunately, approximately one-third of patients are non-adherent to long-term treatment. This highlights the importance of identifying those with positional obstructive sleep apnea (POSA), which affects 25%-35% of the OSA population, as these patients may benefit from alternative therapeutic interventions such as vibrating positional devices or positional pillows. The aim of this prospective randomized crossover study was to assess the efficacy of two different positional therapies (PTs): a positional pillow (Posiform®) and a vibrating belt (Somnofit-belt®), for reducing supine sleep time in POSA patients in the home setting.
Adults with POSA (n=102), diagnosed by polysomnography (PSG) at two university hospitals, were screened, and 19 patients met the criteria for at-home supine sleep and were included. Patients were randomized to use either the vibrating belt first and then the pillow, or the reverse. Patient questionnaires were used to assess sleep quality and comfort, and the Somnibel Pro® device was used to assess patients' sleep position.
A statistically significant reduction in supine sleep time was observed in patients using the vibrating belt compared to baseline (p = 0.0001). No difference was observed for the pillow. There was no significant difference in sleep quality or comfort between the devices. This study also highlights the observation that supine sleep is infrequent in the home setting.
In this study, we have shown a significant reduction in supine sleep time in POSA patients using the vibrating belt, which was not observed with the positional pillow. However, the results must be qualified by the small number of patients included.
阻塞性睡眠呼吸暂停（OSA）是一个可治疗的全球性健康问题，其患病率因肥胖流行和人口老龄化而不断上升。不幸的是，约三分之一的患者不坚持长期治疗。这凸显了识别那些患有体位性阻塞性睡眠呼吸暂停（POSA）患者的重要性，这类患者占OSA人群的25%-35%，因为这些患者可能受益于诸如振动体位装置或体位性枕头等替代治疗干预措施。这项前瞻性随机交叉研究的目的是评估两种不同的体位疗法（PTs）：一种体位性枕头（Posiform®）和一条振动带（Somnofit-belt®），用于减少居家环境中POSA患者的仰卧睡眠时间。
在两家大学医院通过多导睡眠图（PSG）诊断为POSA的成年人（n=102）接受了筛查，19名患者符合居家仰卧睡眠标准并被纳入研究。患者被随机分为先使用振动带然后使用枕头，或者相反的顺序。使用患者问卷评估睡眠质量和舒适度，并使用Somnibel Pro®设备评估患者的睡眠体位。
与基线相比，使用振动带的患者仰卧睡眠时间有统计学意义的减少（p = 0.0001）。使用枕头未观察到差异。两种装置在睡眠质量或舒适度方面没有显著差异。这项研究还突出了在家中仰卧睡眠不常见的观察结果。
在本研究中，我们已表明使用振动带的POSA患者仰卧睡眠时间显著减少，而使用体位性枕头未观察到这一现象。然而，由于纳入患者数量较少，结果必须谨慎看待。
