A method is described for long-term recording of motor activity with a wrist-worn solid-state activity monitor. Movement-induced signals are integrated over predetermined periods (usually 7.5 min) and stored in the memory (1024 8-bit words) of the device. At 5-day intervals the data are transferred into a minicomputer and plotted in graph form. The technique may be used for studying the rest activity cycle and motor activity during sleep under normal life conditions. Sleep disorders and pharmacological effects on sleep can be objectified from the activity plots. Various applications in clinical medicine and in research are illustrated and discussed.
本文描述了一种使用腕戴式固态活动监测器长期记录运动活动的方法。运动诱发的信号在预定时间段（通常为7.5分钟）内进行积分，并存储在设备的存储器（1024个8位字）中。每隔5天将数据传输到小型计算机中，并以图表形式绘制出来。该技术可用于研究正常生活条件下的休息-活动周期和睡眠期间的运动活动。睡眠障碍以及药物对睡眠的影响可以从活动图中客观地体现出来。文中还举例说明了并讨论了该技术在临床医学和研究中的各种应用。
