Many authors have recommended the development and use of automated recording devices as alternatives to self-report measures of activity patterns in chronic pain patients. An electromechanical device is described that can be used to measure downtime or uptime in chronic pain patients. This monitor has several advantages over mercury tilt-switch devices including freedom from plane dependence, resistance to artifact associated with rapid or vigorous movements, and the flexibility to permit conceptualization of sitting time as either uptime or downtime, depending upon placement of the position switch. The monitor consists of a miniature electronic timer, a switching delay circuit and battery pack, an electromechanical position switch, a belt with carrying cases, and a battery recharger. The device has high reliability (agreement coefficients of 1.0) and concurrent validity (r = 0.99) for both downtime and uptime assessments. Research applications and clinical use of this device are discussed as well as directions for the further development of automated recording devices.
许多作者建议开发和使用自动记录设备，以替代慢性疼痛患者活动模式的自我报告测量方法。本文描述了一种机电设备，可用于测量慢性疼痛患者的休息时间或活动时间。与汞倾斜开关设备相比，该监测器具有多个优点，包括不受平面依赖性影响、抵抗与快速或剧烈运动相关的伪迹，以及根据位置开关的放置，灵活地将坐姿时间概念化为活动时间或休息时间。该监测器由一个微型电子定时器、一个开关延迟电路和电池组、一个机电位置开关、一个带携带盒的腰带以及一个电池充电器组成。该设备在休息时间和活动时间评估方面具有高可靠性（一致性系数为1.0）和同时效度（r = 0.99）。本文讨论了该设备的研究应用和临床用途，以及自动记录设备的进一步发展方向。
