To examine temporal and spatial gait parameters in Mexican healthy pediatric subjects to describe normal values which could serve as reference data to eventually compare pathological patterns of the Mexican infant gait.
Descriptive study that analyzed the gait of 120 children (61 boys and 59 girls) between the ages of 6 and 13 years old. Modifying factors (age, gender, and footwear) were recorded and its impact over temporal and spatial gait parameters was assessed. The data was stratified according to the modifying factors. A GAITRite System was used for recording the gait data.
Significant differences were noted for the following factors: age and the use of footwear. As the individual advances in age, a decrease in number of steps, normalized velocity, velocity, cadence, normalized cadence, normalized step and stride length was observed. In contrast, step and stride length increased. Use of footwear increased velocity (normalized and non-normalized), normalized cadence, step and stride length (normalized and non-normalized), and percentage of stance GC phase; cadence and swing GC percentage diminished. Gender stratification showed no significant differences in any temporal and spatial gait parameters. There were also found significant differences with those reported for normal adult and pediatric gait in the literature.
Age and footwear modified gait pattern in the studied sample, while gender apparently did not exert any influence on it.
研究墨西哥健康儿童的时间和空间步态参数，描述正常的参考值，以便最终比较墨西哥婴儿步态的病理模式。
本研究为描述性研究，分析了 120 名 6 至 13 岁儿童（61 名男孩和 59 名女孩）的步态。记录了修正因子（年龄、性别和鞋类），并评估其对时间和空间步态参数的影响。根据修正因子对数据进行分层。使用 GAITRite 系统记录步态数据。
年龄和鞋类使用是重要的影响因素。随着个体年龄的增长，步数、标准化速度、速度、步频、标准化步频、标准化步长和步幅均呈下降趋势。相反，步长和步幅增加。鞋类的使用增加了速度（标准化和非标准化）、标准化步频、步长（标准化和非标准化）和支撑 GC 阶段的百分比；步频和摆动 GC 百分比减少。性别分层在任何时间和空间步态参数上均无显著差异。与文献中正常成人和儿童步态的报告相比，也存在显著差异。
年龄和鞋类改变了研究样本的步态模式，而性别显然没有影响。
