Retained Primitive Reflexes: What Parents Should Know
A reflex finding alone does not explain a child's difficulties or establish a diagnosis. Start with the everyday activities your child finds difficult.
Key points
- A reflex finding alone does not explain a child's difficulties or establish a diagnosis.
- Start with the everyday activities your child finds difficult.
What primitive reflexes are
Primitive reflexes are automatic responses seen in infancy, such as the Moro response and palmar grasp. These responses typically change as voluntary movement develops; the expected timing differs between reflexes.
Some practitioners assess reflex responses as part of a broader developmental or functional evaluation. A response observed during a test does not, by itself, identify the cause of a child's difficulties or establish a diagnosis.
What the evidence can and cannot tell us
Some research reports associations between reflex responses and motor or learning measures. An association does not establish that a retained reflex causes difficulties with handwriting, attention, anxiety or behaviour. These difficulties can have many explanations.
Evidence for reflex-integration programmes improving everyday participation is limited. Families should not be promised that exercises will 'switch off' reflexes or resolve learning or emotional concerns. Ask how a proposed intervention relates to an observed functional difficulty and how meaningful progress will be measured.
When to seek advice
Seek advice when difficulties with movement, self-care, play or school participation affect your child's daily life. Describe specific activities and situations rather than using an online symptom checklist to self-diagnose a retained reflex. Discuss new neurological concerns or loss of previously acquired skills with a medical professional.
An OT assessment can explore the child's goals, strengths, task demands and environment, and recommend practical supports. Reflex testing, if relevant, is only one part of that assessment; it should not replace broader developmental or medical assessment when needed. I assess school-age children across the Gold Coast and surrounds, with parent interviews available by Telehealth.
