In recent years, wrist actigraphy has been scrutinized as a possible supplement to or even replacement for other methods traditionally used to assess the sleep of clinical patients and research subjects. While showing promise for some applications, its accuracy in measuring the nocturnal sleep of insomniacs remains in question. A reexamination of the relevant data indicates that with respect to estimating the total sleep time of insomnia patients, use of the actigraph does not yield significantly lower error than daily sleep logs and predicts only about a third of the variance. However, the actigraph does show some potential for assessing the night-to-night variability of a given individual's sleep, suggesting that it may be most useful for assessing longitudinal changes within a treatment program or experimental protocol.
近年来，腕部活动记录仪作为传统上用于评估临床患者和研究对象睡眠的其他方法的一种可能补充甚至替代方法，受到了仔细审查。虽然它在某些应用中显示出前景，但其在测量失眠症患者夜间睡眠方面的准确性仍存在疑问。对相关数据的重新审视表明，在估计失眠症患者的总睡眠时间方面，活动记录仪产生的误差并不比每日睡眠日志显著更低，并且只能预测约三分之一的方差。然而，活动记录仪在评估个体睡眠的夜间变异性方面确实显示出一些潜力，这表明它在评估治疗方案或实验方案中的纵向变化时可能最有用。
