If differences in motor development can be observed in young infants later diagnosed with autism, then there is potential to detect autism long before a child is old enough to socially interact or to start speaking. In several research studies, abnormal motor patterns were observed in every child that later was diagnosed with autism or Asperger’s Syndrome.
The following are some areas of motor development where differences have been reported:
The child should equally use both arms and legs to push, reach and kick. Once the child starts rolling, he should be able to go to either side.
The absence of crawling or crawling with atypical patterns, such as bottom scooting or crawling with one foot up, is commonly reported.
Rolling with the back arched or rolling stiffly like a pencil has been observed.
