在重症监护病房（MICU）的患者中，睡眠不良和不动是常见的，并与不良结局相关。促进MICU睡眠和动员的干预措施越来越受欢迎，但缺乏可行的工具来衡量其有效性。体动仪可用于大规模、连续测量睡眠和活动，但其在MICU患者中的可行性尚未得到严格评估。评价连续体动计测量在连续MICU患者中的可行性。在知情同意的MICU患者中收集48小时的腕关节和踝关节活动记录数据。使用描述性统计对基于活动描记法的估计睡眠和活动的测量进行总结。使用Cohen κ统计（睡眠量）和组内相关系数（活动）评价腕关节和踝关节测量值之间的一致性。总体而言，48例合格患者中有35例（73%）入组，包括10例需要机械通气的患者。在这些患者中，34例（97%）完成了48小时腕动记录期; 20例（57%）发现器械舒适。腕部装置记录的平均（SD）估计睡眠时间为33.4（8.8）小时（记录时间的72% [19%]），每30秒的时间段运动19.6（17.2）次。踝关节设备记录了43.2（4.1）小时的估计睡眠（记录周期的93% [7%]）和每30秒5.1（6.0）次运动。不间断腕动计是可行的，MICU患者通常耐受良好，可考虑用于未来的大规模研究。在这种情况下，手腕和踝关节活动记录仪对睡眠和活动的测量结果一致性很差，不能互换使用。
Poor sleep and immobility are common in patients in the medical intensive care unit (MICU) and are associated with adverse outcomes. Interventions to promote sleep and mobilization in the MICU are gaining popularity, but feasible instruments to measure their effectiveness are lacking. Actigraphy may be useful for large-scale, continuous measurement of sleep and activity, but its feasibility in MICU patients has not been rigorously evaluated. To evaluate the feasibility of continuous actigraphy measurement in consecutive MICU patients. Wrist and ankle actigraphy data were collected for 48 hours in consenting MICU patients. Actigraphy-based measures of estimated sleep and activity were summarized by using descriptive statistics. Agreement between wrist and ankle measurements was evaluated using Cohen κ statistics (for sleep quantity) and intraclass correlation coefficients (for activity). Overall, 35 of 48 (73%) eligible patients were enrolled, including 10 requiring mechanical ventilation. Of these patients, 34 (97%) completed the 48-hour actigraphy period; 20 (57%) found the devices comfortable. Wrist devices logged a mean (SD) of 33.4 (8.8) hours of estimated sleep (72% [19%] of recording period) and 19.6 (17.2) movements per 30-second epoch. Ankle devices recorded 43.2 (4.1) hours of estimated sleep (93% [7%] of recording period) and 5.1 (6.0) movements per 30 seconds. Uninterrupted actigraphy is feasible and generally well tolerated by MICU patients and may be considered for future large-scale studies. Wrist and ankle actigraphy measurements of sleep and activity in this setting agree poorly and cannot be used interchangeably.
