Motor deficits are not listed as part of the diagnostic criteria for ASD, individuals with these disorders tend to exhibit motor skill deficiencies as well as differences in motor development. Infants with ASD may exhibit hypotonia. In addition, delays may exist in the acquisition of motor milestones and fundamental motor skills. Differences in skills such as gait and manual dexterity persist into childhood.
With that said, my boys differed greatly with their motor deficits. Trenton was not delayed in his motor skills at first. Trenton was walking at 10 months and running at 10 1/2 months. He learned to jump before he was a year old. Andrew, on the other hand, is a few weeks away from being 2 1/2 years old and still can not jump. We have been working with this for a long time. Neither boy can pedal. Sad to say, I am not sure if they will be able to do this anytime soon. At one point, Trenton was not delayed on his motor skills but he is now. Andrew has always been delayed.
Daddy had Andrew outside trying to practice the other day but it is just very difficult for him.
