研究目的：评价动态脑电(EEG)监测仪在评估健康成人睡眠连续性和睡眠结构方面的有效性。方法：14名睡眠良好的健康受试者同时使用动态脑电监测仪(Slear Profiler)和全面多导睡眠图(PSG)蒙太奇。脑电记录是在同一晚从两个设备上收集的，在此期间，睡眠允许不间断地进行八个小时。这项研究是在一个住院的临床研究室进行的。PSG和睡眠档案记录由获得睡眠医学认证的神经科医生委员会评分，记录识别是盲目的。在每个睡眠阶段，以PSG记录作为参考，评估评分的PSG记录、医生评分的睡眠档案记录和由自动算法评分的睡眠档案记录之间的一致性。结果：结果表明，跨阶段的一致性很强。Kappa在N3期和REM期表现最强。所有分期的特异性都很高；WAKE和N1期的敏感度较低，而N2期、N3期和REM期的敏感度较高。与自动评分记录相比，手动评分的睡眠分析器记录的一致性指数有所提高。结论：总的来说，睡眠分析器产生的EEG记录具有与PSG相似的睡眠结构估计。未来的研究应该评估这些设备与具有更长觉醒时间的临床样本之间的一致性，以便更好地了解该设备在估计睡眠连续性指标方面的效用，例如睡眠开始潜伏期和睡眠开始后的觉醒。
Study Objectives: To evaluate the validity of an ambulatory electroencephalographic (EEG) monitor for the estimation of sleep continuity and architecture in healthy adults.Methods: Healthy, good sleeping participants (n = 14) were fit with both an ambulatory EEG monitor (Sleep Profiler) and a full polysomnography (PSG) montage. EEG recordings were gathered from both devices on the same night, during which sleep was permitted uninterrupted for eight hours. The study was set in an inpatient clinical research suite. PSG and Sleep Profiler records were scored by a neurologist board certified in sleep medicine, blinded to record identification. Agreement between the scored PSG record, the physician-scored Sleep Profiler record, and the Sleep Profiler record scored by an automatic algorithm was evaluated for each sleep stage, with the PSG record serving as the reference.Results: Results indicated strong percent agreement across stages. Kappa was strongest for Stage N3 and REM. Specificity was high for all stages; sensitivity was low for Wake and Stage N1, and high for Stage N2, Stage N3, and REM. Agreement indices improved for the manually scored Sleep Profiler record relative to the autoscore record.Conclusions: Overall, the Sleep Profiler yields an EEG record with comparable sleep architecture estimates to PSG. Future studies should evaluate agreement between devices with a clinical sample that has greater periods of wake in order to better understand utility of this device for estimating sleep continuity indices, such as sleep onset latency and wake after sleep onset.
