目的 确定通过腕踝体动记录仪（一种活动测量）连续测量危重患者肢体运动的可行性，并将体动记录仪测量结果与观察到的活动、镇静-躁动量表的主观评分以及患者的心率和血压进行比较。 方法 在一项前瞻性、描述性、相关性研究中，对大学医疗中心内科和冠心病监护室的 20 名成年患者的所有活动进行了 2 小时的观察和记录。每分钟收集手腕和脚踝活动记录仪、心率以及收缩压和舒张压数据。在观察期开始时以及 1 和 2 小时后完成舒适量表和里士满躁动-镇静量表。 结果 手腕活动记录数据与里士满躁动-镇静量表 (r = 0.58) 和舒适量表 (r = 0.62) 的分数以及观察到的患者刺激和活动事件 (r = 0.45) 相关。与收缩压、舒张压和平均动脉压的相关性较弱。手腕和脚踝活动记录仪数据显着相关（r = 0.69；P < .001）；然而，它们的平均值（手腕，418；踝关节，147）显着不同（t = 5.77；P < .001）。 结论 体动记录仪可以连续记录患者的肢体运动。体动记录仪测量结果与患者观察到的活动以及躁动和镇静量表的主观评分密切相关。体动记录仪作为行为研究中使用的连续测量活动可能变得特别重要，并且可以增强对以躁动为特征的过度活动的早期识别和管理。
OBJECTIVES To determine the feasibility of continuous measurement of limb movement via wrist and ankle actigraphy (an activity measure) in critically ill patients and to compare actigraphy measurements with observed activity, subjective scores on sedation-agitation scales, and heart rate and blood pressure of patients.METHODS In a prospective, descriptive, correlational study, all activity of 20 adult patients in medical and coronary care units in a university medical center were observed for 2 hours and documented. Wrist and ankle actigraphy, heart rate, and systolic and diastolic blood pressure data were collected every minute. The Comfort Scale and the Richmond Agitation-Sedation Scale were completed at the beginning of the observation period and 1 and 2 hours later.RESULTS Wrist actigraphy data correlated with scores on the Richmond Agitation-Sedation Scale (r = 0.58) and the Comfort Scale (r = 0.62) and with observed stimulation and activity events of patients (r = 0.45). Correlations with systolic, diastolic, and mean arterial pressures were weaker. Wrist and ankle actigraphy data were significantly correlated (r = 0.69; P < .001); however their mean values (wrist, 418; ankle, 147) were significantly different (t = 5.77; P < .001).CONCLUSIONS Actigraphy provides a continuous recording of patients' limb movement. Actigraphy measurements correlate well with patients' observed activity and with subjective scores on agitation and sedation scales. Actigraphy may become particularly important as a continuous measurement of activity for use in behavioral research and may enhance early recognition and management of the excessive activity that characterizes agitation.
