Basic gait parameters were extracted from 233 healthy subjects--116 men and 117 women, 10 to 79 years of age. The measurements were made in a gait laboratory on a 5.5 m walkway. The results are presented in a series of reference tables for slow, normal, and fast gait. Mean, standard deviation, coefficient of variation, 95% confidence intervals, and 95% prediction intervals were calculated. Significant sex differences exist in all gait parameters. In a two-way analysis of variance (ANOVA) model, there was a statistically significant age-variability for gait speed and step length at normal and fast gait, but not for step frequency. In the step length parameter there was a significant interaction effect of age and sex at normal and fast gait. The reference data are considered valid in an indoor laboratory situation.
从233名健康受试者（116名男性和117名女性，年龄在10至79岁之间）中提取基本步态参数。测量在步态实验室的一条5.5米长的通道上进行。结果以一系列慢、正常和快步态的参考表呈现。计算了均值、标准差、变异系数、95%置信区间和95%预测区间。所有步态参数均存在显著的性别差异。在双向方差分析（ANOVA）模型中，正常和快步态下的步态速度和步长存在统计学上显著的年龄变异性，但步频不存在。在步长参数方面，正常和快步态下年龄和性别存在显著的交互作用。这些参考数据在室内实验室环境中被认为是有效的。
