一个可靠的系统的可用性，以记录睡眠阶段测量容易和自动在门诊设置可能是实用的研究和临床工作。本研究的目的是评估一种新的无线系统（WS），它不需要熟练的准备来自动收集和评分人类睡眠。29名健康成人在睡眠实验室通过WS、多导睡眠图（PSG）和活动记录仪（ACT）进行同步睡眠测量，评估夜在适应夜之前进行。PSG记录由来自不同实验室的两名经验丰富的训练有素的技术人员评分。每个录音都是由两名技术人员根据莱希沙芬和卡尔斯（R&K）标准进行评分的。将WS和ACT与各PSG评分和一致的PSG评分进行比较，并相互比较PSG评分。通过一致性百分比、Cohens kappa和类内相关系数对所有合并时代的每对评分间一致性进行评估。WS与睡眠阶段的两个PSG评分的一致性分别为75.8和74.7%。WS与睡眠/觉醒两项PSG评分的一致性分别为92.6和91.1%，ACT与PSG评分的一致性分别为86.3和85.7%。PSG评分者对睡眠阶段的一致性为83.2%，对睡眠/清醒状态的一致性为95.8%。目前的研究结果表明，WS可能为其他已建立的测量健康成人睡眠的技术提供一种易于使用和准确的补充。
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, Cohens 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.
