研究了半量纲(SD)和无量纲(ND)归一化对5-12岁儿童步态纵向研究结果的影响。对身高和腿长在正常化过程中的使用进行了检查。只有ND分析可以用来识别具有相同加速度的受试者。对儿童步态的分析表明，步长和节奏的组合在5~12岁之间达到特定速度时变化不大。地面反作用力垂直分量的第一个峰值和站立中间低谷值不随年龄变化。我们建议使用ND标准化，而不是SD，以允许不同大小和质量的个体之间进行比较。(C)2002 Elsevier Science B.V.保留所有权利。
The comparative effect of semi-dimensional (SD) and non-dimensional (ND) normalisation on the results of a longitudinal study of gait in 5-12-year old children was investigated. The use of both height and leg length in the normalisation was examined. Only ND analysis could be used to identify subjects with the same accelerations. ND analysis of the children's gait indicated that there was little change in the combination of step length and cadence used to achieve a particular velocity between 5 and 12. The first peak and mid-stance trough values of the vertical component of ground reaction force did not change with age. We recommend the use of ND normalisation rather that SD to allow comparisons between individuals of differing size and mass. (C) 2002 Elsevier Science B.V. All rights reserved.
