Age-dependent gait characteristics and associations with cognition, motor behavior, injuries, and psychosocial functioning were investigated in 138 typically developing children aged 6.7-13.2 years (M = 10.0 years). Gait velocity, normalized velocity, and variability were measured using the walkway system GAITRite without an additional task (single task) and while performing a motor or cognitive task (dual task). Assessment of children's cognition included tests for intelligence and executive functions; parents reported on their child's motor behavior, injuries, and psychosocial functioning. Gait variability (an index of gait regularity) decreased with increasing age in both single- and dual-task walking. Dual-task gait decrements were stronger when children walked in the motor compared to the cognitive dual-task condition and decreased with increasing age in both dual-task conditions. Gait alterations from single- to dual-task conditions were not related to children's cognition, motor behavior, injuries, or psychosocial functioning.
对138名年龄在6.7至13.2岁（平均年龄10.0岁）的发育正常儿童进行了研究，以探讨年龄依赖性步态特征及其与认知、运动行为、损伤和心理社会功能的关系。使用GAITRite步道系统在无额外任务（单任务）以及执行运动或认知任务（双任务）时测量步态速度、标准化速度和变异性。对儿童认知的评估包括智力和执行功能测试；父母报告孩子的运动行为、损伤和心理社会功能。在单任务和双任务行走中，步态变异性（步态规律性指标）均随年龄增长而降低。与认知双任务条件相比，当儿童在运动双任务条件下行走时，双任务步态下降更为明显，且在两种双任务条件下均随年龄增长而降低。从单任务到双任务条件下的步态改变与儿童的认知、运动行为、损伤或心理社会功能无关。
