How children benefit from from overall motor functioning interventions at DDY Image Credit: Supplied Children diagnosed with Autism Spectrum Disorder (ASD) typically develop and present symptoms as early as 2-3 years old. In addition to their behavioural, speech, sensory and social economical difficulties, many children will also experience difficulties in their motor performances. Children achieve early gross motor milestones such as sitting, crawling and walking independently within the expected timeframes, but the quality of their movements may be immature when compared with their peers. As a result, children with ASD may struggle to reach higher level of motor skills such as age-appropriate play skills, riding a bike, balancing and jumping.
