This study was designed to extend research on motor skill development in autism spectrum disorder using a dual-task skill. Nine autistic and 18 non-autistic youths walked without grasping or while reaching to grasp a small or large object. Step extremity ratio, percent time in double support, and normalized speed were quantified. We hypothesized that gait would differ between autistic and non-autistic youth and that differences would be moderated by the phase (approach and grasp) and the complexity of the task (walking and grasping versus walking alone). Although gait parameters were similar during the walking-only trials, the combined task resulted in slower speed and shorter steps in autistic youth, particularly during the grasp phase. These findings, while in a small sample, offer preliminary evidence that autistic youth who show typical gait during simple assessments of motor ability may have difficulties in more complex tasks that require the coordination of movements.
本研究旨在通过双任务技能拓展自闭症谱系障碍中运动技能发展的研究。9 名自闭症和 18 名非自闭症青少年在不抓握或伸手抓小或大物体时行走。量化了步幅比、双支撑时间百分比和标准化速度。我们假设自闭症和非自闭症青少年的步态会有所不同，并且差异会受到任务阶段（接近和抓取）和任务复杂性（行走和抓取与单独行走）的调节。虽然在仅行走试验中步态参数相似，但在组合任务中，自闭症青少年的速度较慢，步幅较短，尤其是在抓取阶段。这些发现虽然样本较小，但初步表明，在运动能力的简单评估中表现出典型步态的自闭症青少年，在需要协调运动的更复杂任务中可能会遇到困难。
