Retained primitive reflexes are immature movement patterns that can often have effects on a child’s overall development. Naturally, these reflexes should “integrate” or disappear during infancy. When a reflex is retained, more mature movement patterns are not developed, which can have an effect on sensory integration, posture, executive functioning skills, and overall neuroplasticity. Recognizing and treating these retained reflexes can have a big impact on a child’s overall development.
