By means of a wrist accelerometer, motor activity of 14 narcoleptic patients was continuously monitored. The accelerometer registered accelerations exceeding a threshold value of 0.1 gr and stored activity integrated over 3 minutes. After a registration period of 20 days, the data were read out, graphically displayed and compared to the patient's diary. Interruptions of night sleep and some sleep attacks during day correlated closely with the patient's diary. However, sleep attacks of less than about 5 minutes duration were not identified, because they could not be differentiated from normal rest. Except for that, activity monitoring with this accelerometer is a useful and simple method for ambulatory activity recording in narcoleptics.
通过腕部加速度计，对14名发作性睡病患者的运动活动进行了连续监测。该加速度计记录超过0.1克阈值的加速度，并存储3分钟内的积分活动。在20天的记录期后，读取数据，以图形方式显示，并与患者的日记进行比较。夜间睡眠中断和白天的一些睡眠发作与患者的日记密切相关。然而，持续时间不到约5分钟的睡眠发作未被识别出来，因为它们无法与正常休息区分开来。除此之外，使用这种加速度计进行活动监测是一种用于记录发作性睡病患者日常活动的有用且简单的方法。
