Abstract

A portable low-cost instrument system for reliable and automatic measurement of "up-time" in chronic pain patients was described. The system used a miniature electronic stopwatch/calculator to accumulate up-time. A mercury tilt switch mounted on the outer thigh was used to control time accumulation. Performance assessment showed excellent reliaility, as well as high concurrent validity (r = 0.999) for the system. Initial field testing with normal subjects and chronic pain patients indicated reliable and easy operation.

摘要

描述了一种用于可靠且自动测量慢性疼痛患者“活动时间”的便携式低成本仪器系统。该系统使用微型电子秒表/计算器来累计活动时间。安装在外大腿上的水银倾斜开关用于控制时间累计。性能评估表明该系统具有出色的可靠性，以及较高的同时效度（r = 0.999）。对正常受试者和慢性疼痛患者进行的初步现场测试表明其操作可靠且简便。
