Yes, motor regression in autism can occur and may signal developmental concerns, though it is less frequently highlighted than communication regression. Children with autism may experience movement loss, where they begin to lose previously acquired motor skills, such as walking, running, or performing tasks requiring coordination, like feeding themselves or holding a pencil. This loss of motor function can be a significant developmental sign of autism, particularly when combined with other autism symptoms.

While not all children with autism experience motor regression, some may show signs of a decline in physical abilities, especially during the toddler years or after a period of typical development. This can be concerning for parents who notice their child regressing in both social and physical skills.

How Motor Regression in Autism Appears

Common signs of motor regression in autism include:

Loss of Coordination:

A child may struggle with tasks that require fine or gross motor skills, such as walking, running, or using utensils, even if they had previously mastered these abilities.

Delayed or Reduced Motor Milestones:

Some children may show a decline in reaching typical motor milestones, such as sitting up, crawling, or standing independently.

Increased Stiffness or Limited Movement:

Motor regression can also involve physical stiffness or difficulty with movement, which may result in a more restricted range of motion.

Recognising motor regression in autism early can help parents and caregivers address developmental concerns and seek appropriate interventions. For expert advice and personalised consultations, visit providers like Autism Detect for one-on-one support specific to your child’s needs.
