活动记录仪适用于研究无法忍受传统睡眠记录技术的人群的睡眠，例如体弱和痴呆的疗养院患者。本研究通过测试腕部活动监测器Actillume的可靠性，与传统的睡眠测量和对疗养院患者的观察，来检查腕动计是否可以准确地反映这一人群的睡眠/清醒活动。Actillume的数据显示为两个变量，总和（规定时期内所有活动运动的总和）和最大活动（规定时期内记录的最大或最大运动），并通过脑电图（EEG）显示。进行比较的一个困难是EEG记录显示弥散性减慢，这使得对睡眠/觉醒活动进行评分变得非常困难，并且难以将EEG用作“金标准”。然而，EEG和Actilume的总睡眠时间的相关性对于总活动为r = 0.91（p < 0.001），对于最大活动为r = 0.81（p < 0.005）。最大活动量与睡眠百分比的相关性为r = 0.78（p < 0.01），总活动量与睡眠百分比的相关性为r = 0.61。Actillume测定的睡眠/觉醒与观察结果的比较导致灵敏度为87%，特异性为90%。我们的结论是Actillume是最可行的技术研究痴呆症护理血红素患者的睡眠和觉醒活动。
Actigraphy is applicable for studying sleep in populations who are unable to tolerate traditional sleep-recording techniques, such as nursing-home patients who are infirm and demented. This study examined whether actigraphy can accurately reflect sleep/wake activity in this population by testing the reliability of a wrist-activity monitor, the Actillume, against traditional sleep measurements and against observations of nursing-home patients. Data from the Actillume are presented as two variables, the sum (total of all activity movements within the prescribed epoch) and the maximum activity (the largest or maximum movement recorded during the prescribed epoch), and by electroencephalogram (EEG). One difficulty in making comparisons was that the EEG records showed diffuse slowing, making it extremely difficult to score sleep/wake activity and making it difficult to use the EEG as a ''gold standard''. Nevertheless, the correlation for total sleep time from EEG and Actillume was r = 0.91 (p < 0.001) for sum activity and r = 0.81 for maximum activity (p < 0.005). Correlations for percent sleep were r = 0.78 (p < 0.01) for maximum activity and r = 0.61 for sum activity. The comparison of sleep/wake determined by the Actillume vs. observations resulted in a sensitivity of 87% and specificity of 90%. We conclude that the Actillume is the most feasible technique for studying sleep and wake activity in demented nursing-heme patients.
