Different gait speed assessment protocols regarding start and stop of walking make comparison between studies impossible. The aim of this study was providing reference equations to estimate a person´s steady-state gait speed from gait speed measured with a test protocol including static start and/or stop.
Gait speed of 150 community-dwelling older adults (mean age 80.5 ± 4.5 years; 61% women) was measured over 4 m with different assessment protocols regarding start and stop of walking on an instrumented walkway. Reference equations to estimate steady-state gait speed from the results of other test protocols were calculated by regression analysis within a fivefold cross-validation.
Mean absolute errors and the root mean squared errors of all reference equations ranged from 0.063 m/s to 0.074 m/s and 0.082 m/s to 0.096 m/s, respectively.
The provided reference equations can help harmonizing results between studies in community-dwelling older adults.
关于步行起始和停止的不同步态速度评估方案使得各研究之间无法进行比较。本研究的目的是提供参考方程，以便根据包含静态起始和/或停止的测试方案所测得的步态速度来估算一个人的稳态步态速度。
在一条装有仪器的通道上，采用关于步行起始和停止的不同评估方案，对150名社区居住的老年人（平均年龄80.5±4.5岁；61%为女性）进行4米的步态速度测量。通过五重交叉验证内的回归分析，计算出从其他测试方案结果估算稳态步态速度的参考方程。
所有参考方程的平均绝对误差和均方根误差分别在0.063米/秒至0.074米/秒以及0.082米/秒至0.096米/秒之间。
所提供的参考方程有助于统一社区居住老年人研究之间的结果。
