This study aimed to analyse the kinematic differences in gait between three groups of toddlers who differed in their weeks of independent walking (IW) experience, but not in anthropometrical characteristics, to determine the relationship between walking experience without the side effect of morphological differences on gait parameters. Twenty-six toddlers participated in this study. Depending on the week of their IW, toddlers were divided into three groups: Group 1 (1-5 weeks of IW), Group 2 (6-10 weeks of IW), and Group 3 (11-15 weeks of IW). Each toddler walked barefooted over a 2-m long pathway, and 3D kinematic data were obtained. A decrease in the upper limb position, hip flexion, and step width, i.e., changes towards the adult gait pattern, were observed in Group 3. Less experienced walkers exhibited a wider step width despite no statistically significant difference in body mass and height between groups. Results of this study show no statistically significant difference in step length between groups, suggesting that step length is more related to height than to the walking experience. The increased step length in more experienced walkers reported in previous studies may therefore be a result of different heights and not walking experience.
本研究旨在分析三组在独立行走周数（IW）上存在差异但在人体测量特征上无差异的学步儿童的步态运动学差异，以确定在无形态差异副作用的情况下行走经验与步态参数之间的关系。26 名学步儿童参与了这项研究。根据 IW 的周数，将学步儿童分为三组：第 1 组（1-5 周 IW）、第 2 组（6-10 周 IW）和第 3 组（11-15 周 IW）。每组学步儿童均赤脚在 2 米长的路径上行走，并获得 3D 运动学数据。第 3 组表现出上肢位置、髋关节屈曲和步宽减小，即向成人步态模式的变化。尽管组间体重和身高无统计学差异，但经验较少的行走者表现出更宽的步宽。本研究结果显示组间步长无统计学差异，表明步长与身高的关系更密切，而不是与行走经验的关系。以前的研究报告称，经验更丰富的行走者的步长增加，这可能是由于身高不同而不是行走经验所致。
