Research progress on early motor abnormalities of children with autism spectrum disorder

There is research evidence to suggest that there is a strong relationship between early motor abnormalities and autism spectrum disorders(ASD), although movement disorders are not included in ASD diagnostic criteria. Children with ASD may/or fine motor movements in early life. Early studies reported that hypotonia, hypoactivity and unusual postures were common findings in the ASD group. Gross motor and fine motor development are delayed in ASD infants due to the difficulty in postural control, and movement disorders can also lead to impaired on motor planning and execution in children with ASD.
