When looking at the development of the muscle chains, it is crucial to look into innate movement patterns (primitive reflexes). These impulses integrate into the brain's circuitry as you mature. Anything that delays their assimilation will affect how the different parts of the brain develop and communicate amongst themselves.
Children with learning disorders (e.g., ADHD) are known to have retained primitive reflexes, which then contribute to their symptoms and levels of dysfunction. This is why it is so important to assess every child as early as possible.
At the adult age, primitive reflexes that are not integrated will contribute to an array of problems, such as poor handwriting, pencil grip, fine muscle control, dexterity, fine motor skills, vision coordination, language problems, movement error cognition, and bad posture. Living with retained primitive reflexes can rob your energy and promote overactivity of the sympathetic system, which comes down to unnecessary stress!
Primitive reflexes are an essential component of your overall health and you should know about it!
