我们研究了193名多发性硬化症（MS）患者的身体活动监测器评分的可靠性，这些患者佩戴了计步器和加速计7天。对于计步器（p =.12）或加速度计（p =.15），各天之间无显著差异，表明可以在单个类内相关（ICC）分析模型中分析工作日和周末。7天的监测产生的ICC估计值为0.93，计步器和加速度计，至少3天产生的可靠性为0.80，计步器和加速度计。结果表明，体力活动监测分数是MS患者体力活动的可靠指标。
We examined the reliability of scores from physical activity monitors in a sample of 193 individuals with multiple sclerosis (MS) who wore a pedometer and an accelerometer for a 7-day period. There were no significant differences among days for the pedometer (p =.12) or the accelerometer (p =.15) indicating that week and weekend days can be analyzed in a single intra-class correlation (ICC) analytic model. The 7 days of monitoring yielded ICC estimates of .93 for both the pedometer and accelerometer, and a minimum of 3 days yielded a reliability of .80 for both the pedometer and accelerometer. Results indicated that physical activity monitor scores are reliable measures of physical activity for individuals with MS.
