在过去的20年里，作为婴儿和儿童睡眠和觉醒的客观测量的活动记录仪越来越受欢迎。然而，该领域缺乏已发表的儿科年龄组睡眠-觉醒识别指南。评分规则变化很大，尽管灵敏度（睡眠与多导睡眠图的一致性）通常很高，但与特异性（清醒一致性）相关的显著限制仍然存在。此外，准确的算法输出和睡眠-觉醒摘要通常需要事先输入睡眠-觉醒期的每日日志和伪影相关信息（例如，非磨损时间），涉及重要的父母合作。白天小睡的评分标准仍然是一个未探索的领域。测量准确性面临的许多问题都是体动记录领域本身固有的，特别是在包含明显运动的睡眠期被错误地归类为清醒的情况下，以及在没有检测到运动的安静清醒状态下，被错误地归类为睡眠的情况下。我们讨论了小儿睡眠活动记录仪的挑战，简要描述了技术基础，并考虑了一些技术方法，可能有助于改善分类的错误，在睡眠-觉醒的歧视。
Actigraphy as an objective measure of sleep and wakefulness in infants and children has gained popularity over the last 20 years. However, the field lacks published guidelines for sleep-wake identification within pediatric age groups. The scoring rules vary greatly and although sensitivity (sleep agreement with polysomnography) is usually high, a significant limitation remains in relation to specificity (wake agreement). Furthermore, accurate algorithm output and sleep-wake summaries usually require prior entry from daily logs of sleep-wake periods and artifact-related information (e.g., non-wear time), involving significant parent co-operation. Scoring criteria for daytime naps remains an unexplored area. Many of the problems facing accuracy of measurement are inherent within the field of actigraphy itself, particularly where sleep periods containing significant movements are erroneously classified as wake, and within quiet wakefulness when no movements are detected, erroneously classified as sleep. We discuss the challenges of actigraphy for pediatric sleep, briefly describe the technical basis and consider a number of technological approaches that may facilitate improved classification of errors in sleep-wake discrimination.
