Objectives : Repetitive and stereotyped behaviors are core symptoms in children with autism spectrum disorders (ASD). The purpose of our study was to investigate the frequency of motor stereotypes in ASD children and their clinical features. Methods : Among 171 ASD children (age range, 3-15), the ASD group with motor stereotypes was defined according to two items in the Korean version of Autism Diagnostic Interview-Revised (K-ADI-R). We compared the clinical features, behavior problems and severity of other domains in the K-ADI-R and executive functions between the ASD group with motor stereotypes and the ASD group without motor stereotypes. Results : Ninety (52.6%) of 171 ASD children had motor stereotypes. The ASD group with motor stereotypes had a lower intelligence quotient score (62.23 vs. 84.94, p<.001) compared to the ASD group without motor stereotypes. The ASD group with motor stereotypes had more impairments in the social interaction domain [adjusted odds ratio (AOR) 1.11, p=.001] and communication domain (AOR 1.15, p=.008). Thought problems and lethargy were more frequent in the ASD group with motor stereotypes than the ASD group without motor stereotypes (AOR 2.059, p=.034 ; adjusted OR 1.045, p=.046). However, no significant differences in executive function were observed between the ASD group with motor stereotypes and the ASD group without motor stereotypes. Conclusion : The ASD group with motor stereotypes showed more impairment in social interaction and communication domains, which are core symptoms of autism. Motor stereotypes may indicate greater severity of ASD.
