This post presents a layman’s overview of the current understanding of autism and its connection to motor difficulties. It does not purport to offer definitive advice or conclusions but aims to encourage further research in this field.


In this context, motor challenges refer to difficulties in controlling and coordinating bodily movements. These issues can impact various aspects of daily life, from basic tasks like buttoning a shirt to more complex activities like playing sports. Common conditions associated with motor difficulties include cerebral palsy, muscular dystrophy, and developmental coordination disorder. Symptoms often manifest as clumsiness, poor balance, shaky hands, and struggles with fine motor skills. These challenges can make seemingly simple tasks, such as writing or tying shoelaces, more demanding. Treatment typically involves therapies, exercises, and assistive devices to improve motor skills and enhance independence.


A significant debate has emerged among researchers regarding the prevalence and impact of motor challenges in people with autism. Some argue that if motor difficulties are both pervasive and persistent and affect other developmental domains, they should be integrated into the diagnostic criteria for autism. This change could raise awareness about motor issues in autistic individuals and lead to earlier diagnosis and intervention. However, some dissenting voices believe that adding motor impairment to the autism definition might only complicate the understanding of the condition without clarifying the origin of motor problems.


Research, including the SPARK study conducted by the Simons Foundation, has shown that a substantial proportion of autistic children  experience motor delays, with a notable emphasis on visuomotor (the integration of visual and motor functions in perception) and ball skills, whole-body coordination, fine motor skills, and general motor skills. These motor challenges are closely linked to social communication, repetitive behaviour, cognitive, language, and functional delays.


Some argue that motor delays in autism are mainly found in children with co-occurring intellectual disabilities. However, studies have demonstrated that a significant number of autistic children without intellectual disability still face motor delays. Additional research is required to understand how motor issues in autism differ from those in other developmental disorders.


Interventions for motor difficulties are crucial, as they impact an individual’s ability to perform daily tasks and participate in physical activities, social interactions, and other life experiences. Therefore, it is essential to address motor challenges from an early age and integrate motor skills into daily activities.


Motor development plays a pivotal role in a child’s ability to explore their surroundings and engage in learning and development. Subtle motor delays in infancy can have far-reaching effects on other areas of development, such as language. Therefore, early identification and intervention for motor challenges are essential.


While discussions on including motor impairment in the autism diagnosis continue, it is vital to acknowledge the pervasive nature of motor difficulties among autistic individuals and their impact on daily functioning and participation. It is essential to recognise and address motor challenges early in life and to design interventions that combine movement and exploration with social and communicative opportunities.


In conclusion it is essential to stress that autistic individuals should receive support tailored to their specific needs, whether or not motor difficulties are included in the diagnostic criteria. What is certainly needed is a better understanding of the types of skills affected and preserved in different groups of children to develop more effective interventions.
