The widespread use of actigraphy has led to the recognition that a number of methodological issues have to be addressed to facilitate an increased acceptability of this relatively new method. These methodological issues include actigraph placement, reliability, and sensitivity, and the phenomenon known as the "first night effect." Our findings have demonstrated that actigraphy is a reliable instrument for assessment of sleep and wakefulness. In addition, actigraph placement and reliability do not constitute a significant methodological problem as no differences were found in all of these studies. We have also observed no first-night effects associated with sleep-wake monitoring with actigraphy.
活动记录仪的广泛使用使人们认识到，必须解决一些方法学问题，以提高这种相对较新的方法的可接受性。这些方法学问题包括活动记录仪的放置、可靠性、敏感性以及被称为“首夜效应”的现象。我们的研究结果表明，活动记录仪是评估睡眠和觉醒的可靠工具。此外，活动记录仪的放置和可靠性并不构成重大的方法学问题，因为在所有这些研究中均未发现差异。我们还观察到，使用活动记录仪进行睡眠-觉醒监测不存在首夜效应。
