这项研究的目的是评估七种商业活动监测器在测量不同行走能力的老年人步数方面的准确性，并评估监测器的可接受性和可用性。43名参与者(年龄=87+/-5.7岁)完成了步速评估，两次戴着活动监测器的步行试验，以及关于可用性特征和活动监测器偏好的问卷调查。Accuplit AX2710加速度计的准确度最高(93.68%+/-13.95%)，而Fitbit电荷最低(39.12%+/-40.3%)。设备的精确度根据辅助设备的使用而有所不同，而且没有一个监视器在步态速度上是准确的
The aim of this study was to evaluate accuracy of seven commercial activity monitors in measuring steps in older adults with varying walking abilities and to assess monitor acceptability and usability. Forty-three participants (age = 87 +/- 5.7 years) completed a gait speed assessment, two walking trials while wearing the activity monitors, and questionnaires about usability features and activity monitor preferences. The Accusplit AX2710 Accelerometer Pedometer had the highest accuracy (93.68% +/- 13.95%), whereas the Fitbit Charge had the lowest (39.12% +/- 40.3%). Device accuracy varied based on assistive device use, and none of the monitors were accurate at gait speeds
