Visual sleep scoring is the obligatory reference for sleep analysis. An essential step in sleep scoring is sleep staging. This technique was first described in 1937 and later adapted 3 times: first, in 1957, after the detection of rapid eye movement (REM) sleep, when electrooculography (EOG) was added; second, in 1968, when sleep staging was standardized and electromyography (EMG) was added; and third, in 2007, to integrate accumulated knowledge from sleep science, adding arousals and respiratory, cardiac, and movement events. In spite of the dramatic changes that have taken place in recording and storing techniques, sleep staging has undergone surprisingly few changes. The argument of the present comment is that sleep staging was appropriate as long as sleep biosignals were recorded in the analog mode as curves on paper, whereas this staging may be insufficient for digitally recorded and stored sleep data. Limitations of sleep staging are critically discussed and alternative strategies of sleep analysis are emphasized.
视觉睡眠评分是睡眠分析的必要参考标准。睡眠分期是睡眠评分的关键步骤。这项技术于1937年首次被描述,后来经过了3次调整:第一次是在1957年,在检测到快速眼动(REM)睡眠后,增加了眼电图(EOG);第二次是在1968年,睡眠分期被标准化并增加了肌电图(EMG);第三次是在2007年,为整合睡眠科学积累的知识,增加了觉醒以及呼吸、心脏和运动事件。尽管记录和存储技术发生了巨大变化,但睡眠分期却几乎没有改变。本评论的观点是,只要睡眠生物信号以模拟模式记录在纸上作为曲线,睡眠分期就是合适的,而这种分期对于数字记录和存储的睡眠数据可能并不充分。本文批判性地讨论了睡眠分期的局限性,并强调了睡眠分析的替代策略。
