The present study was designed to investigate body position changes resulting from wearing a Rematee Bumper Belt (Rematee, Canada) during sleep. The majority of obstructive sleep apnea (OSA) patients will experience up to two times as many apneas and hypopneas while supine relative to lateral or prone body positions during sleep. It has been suggested that a positional therapy device could reduce the number of apneas and hypopneas in such patients. The present study was conducted to determine whether the Rematee Bumper Belt positional therapy device could prevent healthy subjects from sleeping in the supine position. Test subjects wore the belt for one to two nights. Each belt was equipped with an accelerometer that was used to measure the orientation of the belt relative to the horizontal plane. The results suggest that the belt creates an exclusion zone approximately 80° wide centred near the supine orientation, where subjects are effectively prevented to enter. Results of the present preliminary study suggests that the Rematee Bumper Belt positional therapy device is effective at limiting healthy subjects from sleeping in a supine position. The device appears to be most effective between 150° and 230°. A device with this capability may provide an inexpensive and potentially effective alternative treatment option for patients with OSA. This device has the capacity for reducing snoring and the apnea-hypopnea index in individuals with positional OSA.
本研究旨在调查睡眠期间佩戴Rematee防撞带（加拿大Rematee公司）所导致的身体姿势变化。大多数阻塞性睡眠呼吸暂停（OSA）患者在睡眠时仰卧位相对于侧卧位或俯卧位会经历多达两倍的呼吸暂停和呼吸浅慢。有人提出，一种定位治疗装置可以减少此类患者的呼吸暂停和呼吸浅慢次数。本研究旨在确定Rematee防撞带定位治疗装置是否能防止健康受试者仰卧位睡眠。测试对象佩戴该腰带一到两个晚上。每条腰带都配备了一个加速度计，用于测量腰带相对于水平面的方向。结果表明，该腰带在仰卧位方向附近形成了一个约80°宽的禁区，受试者被有效阻止进入该区域。本初步研究结果表明，Rematee防撞带定位治疗装置在限制健康受试者仰卧位睡眠方面是有效的。该装置在150°至230°之间似乎最为有效。具有这种功能的装置可能为OSA患者提供一种廉价且潜在有效的替代治疗选择。该装置有能力减少体位性OSA患者的打鼾和呼吸暂停低通气指数。
