Sensory Processing Difficulties and Primitive Reflexes 101
Sensory processing difficulties.
For many parents of neurodivergent children, sensory processing difficulties might be the first thing that they noticed as “different” from peers.
I have used the term Sensory Processing Difficulties in this blog title as opposed to “disorder” because a disorder is a permanent condition – and a diagnosis that doesn’t exist universally. In my work, I look at the expression of the brain and nervous system – I do not diagnose because by working with neuriplasticity, a set of symptoms/presentations change.

This article explains how movement and the integration of primitive reflexes can really help reduce or even eliminate the sensory challenges of someone with SPD.
What causes sensory processing disorder (SPD)?
In brief, sensory processing disorder (SPD) or sensory processing challenges are down to a differently wired brain. The part of the brain called the Reticular Activating System (RAS) – within the brainstem – has not formed strong enough neural connections with the thalamus and higher sensory processing levels of the neocortex. This means that the brain cannot process sensory input efficiently, so we see sensory overwhelm, distractedness or even fear.
The involuntary movements we make as foetuses and newborns are doing a vital job: They are forming neural connections. These involuntary movements – reflexes – should disappear within the first year of life, giving way to adult postural reflexes and conscious movement, controlled by the cerebellum. However, if these primitive reflexes remain active in the system, it will mean that the brain has not formed the optimal neural connections from the brainstem, and consequently we may see sensory processing, motor coordination, emotional or behavioural challenges.
In my clinic, I assess for primitive reflexes and then work with the child and their parents to help integrate reflexes that might be causing challenges. This is done by repeating precisely the movement patterns that foetuses and newborns make, which helps the reflexes gradually integrate and helps the brain and central nervous system move to the next stage of development. It is important to remember that reflex integration is not a quick fix – in fact, it can take months for people to move on from their old patterns of posture and behaviour. However, you will see significant change.
What does Sensory Processing Disorder (SPD) look like?
You might notice some of the following (not an exhaustive list):
- Doesn’t respond to name
- Zones out
- Stims (hand flapping, making noises)
- Difficulties with focus and concentration
- Chews or spits on things
- Restrictive food intake
- Difficulties with motion / balance /coordination
Can a child overcome sensory processing disorder?
Using a bottom-up approach by addressing the nervous system, in a nutshell, yes. We can work to dramatically reduce these difficulties by calming the nervous system.
I had one little boy in clinic whose parents had marked around fifty of his frequent sensory behaviours in Angie Voss’s excellent book Understanding Your Child’s Sensory Signals. Following just three months of a reflex integration programme using RMTi (Rhythmic Movement Training International) methodology, this reduced to just fourteen sensory signals, and two years further on, just four. The sensory signals included behaviours such as flapping, spinning, humming, chewing, dribbling, making eye contact, etc. He is now a calmer, more present child, able to express his feelings verbally – as opposed to his nervous system being on constant alert.
You can also try to include various movements into your child’s day, every day, although when working with emotional or behavioural challenges, it is preferable to see a trained professional.

Try the following:
Cat arches, snow angels, star jumps, lying on back and pretending to be an anemone and slowly opening to become a starfish, and then back to anemone.
I hold a clinic in a home environment. in the Sussex countryside, and have after school and weekend appointments. Please contact me if you would like to discuss or find out more.
