Abstract
Context: Despite the roots of stereotypic patterns as motor behavior and pointing out some prevalent motor impairments in children with autism spectrum disorder (ASD), the assessment of motor development impairments as an introduction to the incidence of early symptoms of ASD has still been overlooked. Therefore, the present systematic review aims to assess the relationship between motor impairments and autism symptoms. Evidence Acquisition: The PubMed, Scopus, ProQuest, Google Scholar, and Web of Science databases were searched by two individuals separately using the following keywords: Autism spectrum disorder, Motor impairment, Motor delay, Fundamental movements (jumping, hopping, bounding, manipulating, chewing, and reaching objects), Gross and fine movements, Diagnosis, and Behavioral symptoms. The searches were performed within 2000 and April 2022. Results: After completing the search process, a number of 17 articles were entered into the study based on the inclusion and exclusion criteria. The articles were of low to moderate quality. Given the performed assessments, there is a significant relationship between motor impairments and behavioral symptoms in children with ASD. Conclusions: According to the present information, it can be concluded that motor impairment is possibly associated with the behavioral symptoms of ASD. Further research is required to determine the exact relationship between motor subsets and behavioral symptoms.
