Actigraphy devices are used in sleep medicine. The Actiwatch 2 (Philips Respironics) was an example of a frequently used device in this field. Nevertheless, the discontinuation of this device has led to an increased necessity for the implementation of other available actigraphy methods capable of providing objective information. The objective of this study was to assess the performance of the new ActTrust 2 compared to the Actiwatch 2 model.
This observational prospective study included 9 participants (77.760 activity logs) who were monitored for 7 days using 2 actigraphy wrist devices (ActTrust 2 and Actiwatch 2) simultaneously. The following variables were evaluated: midline estimating statistic of rhythm, amplitude, and acrophase; intradaily variability; interdaily stability; relative amplitude; and the mean of 5 consecutive hours with the lowest activity and the 10 consecutive hours with the highest activity. Furthermore, total sleep time, time in bed, sleep efficiency, sleep onset latency, wake after sleep onset, and awakenings were also included.
Actigraphy models indicated statistically significant differences in activity levels. Regarding the analysis of circadian rest-activity rhythms, 10 consecutive hours with the highest activity, midline estimating statistic of rhythm, and amplitude also exhibited these differences. Furthermore, the analysis of sleep-wakefulness revealed significant differences in the sleep onset latency and the number of awakenings.
The ActTrust 2 and Actiwatch 2 models showed equivalent results in measuring circadian rest-activity rhythm and sleep. However, caution is advised when interpreting parameters such as midline estimating statistic of rhythm, amplitude, sleep onset latency, awakenings, and 10 consecutive hours with the highest activity variables.

活动记录仪在睡眠医学中有所应用。Actiwatch 2（飞利浦伟康公司）是该领域常用设备的一个例子。然而，该设备的停产使得采用其他能够提供客观信息的活动记录方法变得愈发必要。本研究的目的是评估新型ActTrust 2与Actiwatch 2型号相比的性能。
这项观察性前瞻性研究纳入了9名参与者（77760份活动记录），他们同时使用2种活动记录腕部设备（ActTrust 2和Actiwatch 2）进行了7天的监测。评估了以下变量：节律的中线估计统计量、振幅和峰相位；日内变异性；日间稳定性；相对振幅；以及活动量最低的连续5小时和活动量最高的连续10小时的平均值。此外，还包括总睡眠时间、卧床时间、睡眠效率、入睡潜伏期、睡眠中觉醒和觉醒次数。
活动记录模型显示活动水平存在统计学上的显著差异。关于昼夜休息 - 活动节律的分析，活动量最高的连续10小时、节律的中线估计统计量和振幅也表现出这些差异。此外，睡眠 - 觉醒分析显示入睡潜伏期和觉醒次数存在显著差异。
ActTrust 2和Actiwatch 2型号在测量昼夜休息 - 活动节律和睡眠方面显示出等效结果。然而，在解释诸如节律的中线估计统计量、振幅、入睡潜伏期、觉醒次数以及活动量最高的连续10小时等变量时，建议谨慎。
