The availability of a reliable system to record sleep stage measures easily and automatically in ambulatory settings could be of utility for research and clinical work. The aim of this study was to evaluate a novel wireless system (WS) that does not require skilled preparation for the automatic collection and scoring of human sleep. Twenty-nine healthy adults underwent concurrent sleep measurement via the WS, polysomnography (PSG) and an actigraph (ACT) in a sleep laboratory for one assessment night preceded by an acclimation night. The PSG recordings were scored by two experienced trained technicians from separate laboratories. Each recording was scored by both technicians to Rechtschaffen and Kales (R&K) criteria. The WS and ACT were compared with each of the PSG scores and a consensus PSG score, and the PSG scores were compared with each other. Inter-rater agreement was assessed for each pair over all pooled epochs by percentage agreement, Cohen's kappa and intraclass correlation coefficient. The WS agreement with each of the two PSG scores for sleep stages was 75.8 and 74.7%, respectively. WS agreement with each of the two PSG scores for sleep/wakefulness was 92.6 and 91.1%, ACT agreement with PSG was 86.3 and 85.7%. The PSG scorers' agreement with each other for sleep stages was 83.2%, and for sleep/wakefulness was 95.8%. The findings from the current study indicate that the WS may provide an easy to use and accurate complement to other established technologies for measuring sleep in healthy adults.
在非卧床环境中，能够可靠地记录睡眠阶段的简易自动系统对研究和临床工作可能具有实用性。本研究的目的是评估一种新的无线系统（WS），它不需要对自动收集和评分人类睡眠进行熟练的准备。29 名健康成年人在睡眠实验室中进行了一次评估，在一次适应夜间之后，同时通过 WS、多导睡眠图（PSG）和活动记录仪（ACT）进行睡眠测量。PSG 记录由两个来自不同实验室的经验丰富的经过培训的技术人员进行评分。每个记录都由两名技术人员根据 Rechtschaffen 和 Kales（R&K）标准进行评分。WS 和 ACT 与每个 PSG 评分和共识 PSG 评分进行了比较，并对 PSG 评分进行了相互比较。通过百分比一致、Cohen's kappa 和组内相关系数，评估了每个对在所有汇总时段的每个对的评分者间一致性。WS 与两个 PSG 评分中睡眠分期的一致性分别为 75.8%和 74.7%。WS 与两个 PSG 评分中睡眠/觉醒的一致性分别为 92.6%和 91.1%，ACT 与 PSG 的一致性分别为 86.3%和 85.7%。PSG 评分者之间对睡眠分期的一致性为 83.2%，对睡眠/觉醒的一致性为 95.8%。当前研究的结果表明，WS 可能为健康成年人的睡眠测量提供一种易于使用且准确的其他已建立技术的补充。
