To clarify factors affecting motor actions in children with intellectual disabilities, relationships between three aspects of motor actions, such as speed, accuracy and carefulness, and chronological age (CA), intelligence quotient (IQ), clinical type (Down syndrome, autism) were investigated. The subjects were 54 children with intellectual disabilities (mean age 15.0 years, mean IQ 46.7, 11 children with Down's syndrome and 14 children with autism). We conducted two motor tasks, such as a seal affixation task and tray carrying task. The seal affixation task is fine motor task which can separately measure the speed and accuracy, and the tray carrying task is gross motor task which can separately measure the speed and carefulness. The results were as follows: (a) the relationship between motor actions and CA was not clear. (b) The subject's IQ was clearly related to the accuracy of motor action. (c) The clinical type was clearly related to the speed of motor actions, i.e., persons with Down syndrome were slow. However, the relationship between motor actions and autism was not clear.
