Motor milestone development in young children with autism spectrum disorders: an exploratory study.

This study aimed to determine if a sample of children currently diagnosed with autism spectrum disorders (ASDs) would have shown motor milestone delays before age three as compared to typically developing children. Given delays in motor skills, the study also strived to determine which specific skills might be delayed. Parents of 44 children who had been diagnosed with ASDs answered survey questions related to their child’s early motor milestone development. Survey responses were compared to Bayley’s motor milestone data for typically developing children. Results suggested that all 44 children (age range 82–90 months) with ASDs were delayed on all 26 motor milestones. Specifically, children with autistic disorder (n = 26) were significantly delayed on 11 motor milestones; nine of them delayed before age two. Children with Asperger Syndrome (n = 18) showed significant delay on four milestones; three of them delayed before the age of two. [ABSTRACT FROM AUTHOR]
