This study explores the effects of visual condition and target size during four reach-to-grasp tasks between autistic children and healthy controls. Twenty children with autism and 20 healthy controls participated in the study. Qualisys motion capture system and kinematic measures were used to record movement. Autistic group showed significantly longer movement time, larger normalized jerk score, more movement unit than controls, especially in non-visual feedback and small target blocks. Autistic group also showed significantly larger maximal grip aperture and normalized maximal grip aperture in visual feedback condition than controls. Autistic children demonstrate motor coordination problems and also depend on more visual cuing in high accuracy tasks. Autistic children develop other compensatory skills while performing tasks.
本研究探讨了自闭症儿童与健康对照组在四项抓握任务中视觉条件和目标大小的影响。20名自闭症儿童和20名健康对照组参与了该研究。使用Qualisys运动捕捉系统和运动学测量方法记录运动。自闭症组的运动时间明显更长，标准化急动评分更高，运动单元比对照组更多，尤其是在非视觉反馈和小目标组块中。自闭症组在视觉反馈条件下的最大抓握孔径和标准化最大抓握孔径也明显大于对照组。自闭症儿童表现出运动协调问题，并且在高精度任务中也更依赖视觉提示。自闭症儿童在执行任务时会发展出其他补偿技能。
