ABSTRACT The primary aim of this study was to kinematically assess how children with autism spectrum disorder (ASD) plan and control their handwriting actions. Forty-three boys aged between 8 to 12 years were included in the present analysis; 23 with ASD and 20 typically developing (TD) controls. Sophisticated objective and quantifiable assessment of movement metrics and dynamics was applied across a series of basic cursive handwriting sequences. Children with ASD demonstrated atypical control of handwriting metrics and dynamics, as well as significantly greater neuromotor noise relative to age-matched peers. They also engaged in less regular monitoring and regulation of their movement during the handwriting task. This study provides new insights into the way children with ASD plan and sequence their handwriting movements. Overall, results revealed that even at a basic level, children with ASD appear to have a breakdown in their ability to control and regulate their handwriting movements. This has important implications for the school-aged child who constantly engages in handwriting tasks within the classroom environment and provides insight into possible directions for future intervention.

电机控制和调节问题是 ASD 电机配置文件的一部分吗？笔迹研究

摘要 本研究的主要目的是评估自闭症谱系障碍 (ASD) 儿童如何计划和控制他们的笔迹行为。43 名年龄在 8 至 12 岁之间的男孩被纳入本分析；23 个 ASD 和 20 个典型发育 (TD) 控制。对运动指标和动态的复杂客观和可量化的评估应用于一系列基本的草书手写序列。患有 ASD 的儿童表现出对笔迹指标和动态的非典型控制，以及相对于年龄匹配的同龄人明显更大的神经运动噪音。在手写任务期间，他们还对自己的运动进行了较少的定期监控和调节。这项研究为 ASD 儿童计划和排序他们的手写动作的方式提供了新的见解。全面的，结果显示，即使在基本水平上，患有 ASD 的儿童似乎在控制和调节书写动作的能力方面也出现了故障。这对于在课堂环境中不断从事手写任务的学龄儿童具有重要意义，并为未来干预的可能方向提供了见解。
