身体机能指标预测老年人的健康和功能。特别是步行速度一直预测发病率和死亡率。然而，简单的步行测量可能不能反映一个人的典型能力。使用一个系统，不引人注目的，连续测量步行活动在一个人的家里，我们检查步行速度指标及其与功能的关系。在76名独立生活的人（平均年龄86岁）中，我们测量了在他们年度临床评估的四周内走过一排被动红外运动传感器的每一个实例。计算步行速度和这些测量的方差，并与步态、运动功能和认知的传统测量进行比较。每天步行的中位次数为18 ± 15次。总体平均步行速度为61 ± 17 cm/sec。特征性快速行走速度为96 cm/sec。男人走路的频率和速度和女人一样快。那些使用助行器的人走得明显较慢，变化更大。早上的速度明显快于下午/晚上的速度。在家里步行速度显着相关的几个神经心理学测试以及测试的运动性能。不引人注目的家庭步行评估是步行功能的生态有效措施。它们提供了以前无法达到的日常运动功能指标（周期性，可变性，最小和最大速度范围）。
Physical performance measures predict health and function in older populations. Walking speed in particular has consistently predicted morbidity and mortality. However, single brief walking measures may not reflect a person’s typical ability. Using a system that unobtrusively and continuously measures walking activity in a person’s home we examined walking speed metrics and their relation to function. In 76 persons living independently (mean age, 86) we measured every instance of walking past a line of passive infra-red motion sensors placed strategically in their home during a four-week period surrounding their annual clinical evaluation. Walking speeds and the variance in these measures were calculated and compared to conventional measures of gait, motor function and cognition. Median number of walks per day was 18 ± 15. Overall mean walking speed was 61 ± 17 cm/sec. Characteristic fast walking speed was 96 cm/sec. Men walked as frequently and fast as women. Those using a walking aid walked significantly slower and with greater variability. Morning speeds were significantly faster than afternoon/evening speeds. In-home walking speeds were significantly associated with several neuropsychological tests as well as tests of motor performance. Unobtrusive home walking assessments are ecologically valid measures of walking function. They provide previously unattainable metrics (periodicity, variability, range of minimum and maximum speeds) of everyday motor function.
