OBJECTIVE: The purpose of the present study was to assess the motor skills performance of preschoolers with autism spectrum disorder after eight weeks of physical activity intervention.METHODS: Participants included 5 children, 4 male and 1 female, from 62 to 81 months old, who were attending the identical special kindergarten. Both the quantitative and qualitative aspects of the children's performance were examined. With regards to the quantitative examination, participants were measured using the Movement Assessment Battery for Children (Henderson & Sugden, 1992). Qualitative results were obtained through personal observation. Each motor skills intervention program continued for eight weeks, and children were tested in both pre and post intervention phases.RESULTS: Over the course of the intervention, four of the participants improved their motor skills, while one did not.CONCLUSIONS: This study concluded that even preschool children with autism can improve their motor and social skills if they are involved in a physical activity at least twice a week. The physical activity program could improve their motor and social skills which could help them in their future development.
