[Purpose] The relationship between fine and gross motor function and visuospatial working memory in children with autism spectrum disorder remains unclear. This study examined whether visuospatial working memory is associated with gross or fine motor skills in children with developmental disabilities and motor coordination disorders. [Participants and Methods] The study included 30 children with autism spectrum disorder (24 boys and 6 girls; mean age: 9.5 ± 2.2 years) enrolled in child development support and after-school daycare service centers in Osaka Prefecture. Fine motor skills, gross motor skills, visuospatial working memory, and developmental disabilities were assessed. Data were analyzed using Spearman's rank correlation and multiple regression analyses. [Results] A significant relationship was observed between fine motor skills and visuospatial working memory, and a positive correlation remained after controlling for age. Multiple regression analysis with fine motor scores as the dependent variable and age, visuospatial working memory, and Strengths and Difficulties Questionnaire scores as independent variables demonstrated a significant association only for visuospatial working memory. [Conclusion] The study findings suggest that factors influencing fine and gross motor skills vary, highlighting the need for skill-specific interventions to address deficiencies effectively.
[目的] 自闭症谱系障碍儿童的精细和粗大运动功能与视觉空间工作记忆之间的关系尚不清楚。本研究调查了发育障碍和运动协调障碍儿童的视觉空间工作记忆是否与粗大或精细运动技能相关。[参与者与方法] 本研究纳入了30名自闭症谱系障碍儿童（24名男孩和6名女孩；平均年龄：9.5±2.2岁），他们均在大阪府的儿童发育支持和课后日托服务中心登记。对精细运动技能、粗大运动技能、视觉空间工作记忆和发育障碍进行了评估。使用斯皮尔曼等级相关分析和多元回归分析对数据进行分析。[结果] 观察到精细运动技能与视觉空间工作记忆之间存在显著关系，在控制年龄后仍呈正相关。以精细运动分数为因变量，年龄、视觉空间工作记忆和长处与困难问卷分数为自变量的多元回归分析表明，仅视觉空间工作记忆存在显著关联。[结论] 研究结果表明，影响精细和粗大运动技能的因素各不相同，这凸显了针对特定技能进行干预以有效解决缺陷的必要性。
