The Nervous System Side of Sensory Processing Disorder
Sensory Processing Disorder (SPD) is more than a behavioral challenge. It involves how your child’s brain and nervous system receive, organize, and respond to sensory information. 🧠
For some kids, everyday sounds, clothing, lights, and crowded spaces feel overwhelming. Others constantly seek movement through jumping, spinning, crashing, or chewing. Many experience a combination of both. When a child’s nervous system is constantly on high alert, everyday sensory experiences become harder to manage.
That’s why understanding nervous system regulation is such an important part of the conversation. At Innate Family Chiropractic, we take a neurologically-focused approach, looking beyond symptoms to understand your child’s history, stress patterns, and nervous system function.
Through INSiGHT Scans, we assess indicators of autonomic regulation and neuromuscular tension to help guide individualized chiropractic care. While these scans do not diagnose SPD, they provide additional information about your child’s nervous system. Our goal isn't to change who your child is. It's to support their ability to regulate, adapt, and navigate everyday challenges with greater confidence.
If your child covers their ears when a toilet flushes, refuses certain clothes because of the way they feel, melts down in crowded places, or seems like they constantly need to jump, spin, crash, chew, or move, you have probably spent a lot of time trying to figure out what is going on.
Today I want to talk about Sensory Processing Disorder, or SPD, and especially the piece that I think gets overlooked way too often: the nervous system.
Because sensory processing is a neurological job.
Your child’s brain and nervous system are constantly taking in information from the world around them. Sound. Light. Touch. Movement. Smell. Even information about where their body is in space.
And all of that information has to be received, filtered, organized, and responded to appropriately.
For most of us, that happens without us even thinking about it. But for a child struggling with sensory processing, that system can have a much harder time deciding what information matters, what can be ignored, and how strongly the body should respond.
That is why SPD can look so different from one child to another.
Some kids are hypersensitive. Everything feels turned up. Sounds seem louder. Clothing feels irritating. Certain foods are unbearable. Bright lights, busy rooms, haircuts, brushing teeth, or unexpected touch can send their nervous system straight into overwhelm.
Other kids are sensory-seeking. Their nervous system is constantly looking for more input. They jump off furniture, crash into things, spin, wrestle, chew on their shirts, touch everything, or seem like they are physically incapable of sitting still.
And plenty of kids are a combination of both.
They might crave movement but hate loud sounds. They might want really tight hugs but pull away from light touch.
That is why looking only at the behavior can be so misleading.
A meltdown in the grocery store might look like a behavior issue from the outside. But if your child’s nervous system is already processing the lights, the music, the people, the cart moving, and everything else as overwhelming input, that meltdown is often the point where their system simply has no more capacity.
And parents, I know how exhausting that can be.
You start planning your entire day around what your child can tolerate. You cut tags out of every shirt. You bring headphones everywhere. You avoid certain restaurants. You leave birthday parties early. You spend ten minutes preparing them for something that takes everyone else thirty seconds.
And eventually you start wondering, “Why is everything so hard for my child?”
A lot of families begin with really good strategies.
They create predictable routines. They use movement breaks. They try weighted blankets, compression, quiet spaces, sensory diets, occupational therapy, and different ways of preparing their child for transitions.
Those tools are incredibly valuable.
But here is the question I want parents to ask:
Why is their nervous system needing so much help regulating sensory information in the first place?
Because before the sound reaches their ears and becomes a reaction, before the shirt touches their skin and becomes a meltdown, before their body starts craving constant movement, the nervous system has to process that input.
And one of the systems heavily involved in that regulation is the autonomic nervous system.
That is the part of your nervous system that runs automatically in the background. It helps regulate heart rate, breathing, digestion, sleep, stress responses, and the body’s ability to move between activation and relaxation.
Think about it like a gas pedal and a brake pedal.
The sympathetic side is your gas pedal. It helps you react, move, focus, protect yourself, and respond to stress.
The parasympathetic side is more like the brake. It helps your body slow down, recover, digest, rest, and return to a calmer baseline.
Your child needs both.
The problem is when the gas pedal stays pushed down and the nervous system has trouble finding the brake.
Now normal sensory input starts arriving in a system that is already on high alert.
A sound that should be annoying becomes unbearable.
A transition that should be manageable becomes threatening.
A shirt seam that most of us barely notice becomes the only thing that child can think about.
And that stress pattern does not usually come from one single event.
In our office, we look at the child’s entire story through what we call thoughts, traumas, and toxins.
Thoughts include emotional stress, school demands, major changes, and sensory overload.
Traumas include pregnancy and birth stress, falls, injuries, sports, and all the physical stress kids accumulate as they grow.
Toxins include illnesses, medications, nutrition challenges, and environmental stressors the body has to process.
For some kids, birth trauma is an important part of that story. For others, it is the accumulation of stress over months or years.
Either way, we are looking for patterns that tell us the nervous system has become overloaded and less adaptable.
And this is where neurologically-focused chiropractic care becomes really important.
At Innate, we do not want to guess based only on symptoms.
We use INSiGHT Scans to give us an objective look at how your child’s nervous system is functioning and adapting in ways a standard physical exam does not show.
We look at heart rate variability, which gives us information about autonomic adaptability.
We use thermal scanning to look for patterns of autonomic stress.
And we use surface EMG to evaluate neuromuscular tension and how the nervous system is controlling muscles..
These scans do not diagnose SPD.
What they do is help us identify neurological stress patterns and areas of subluxation that can interfere with how efficiently the brain and body communicate.
Then we combine those scans with your child’s history and our neuro-tonal assessment.
We want to know when the sensory struggles started. What pregnancy and birth looked like. How they sleep. How digestion is functioning. What transitions are like. Whether they are constantly on the move or easily overwhelmed. What you have already tried and where your biggest struggles are right now.
From there, we create an individualized care plan.
The adjustments we use with kids are gentle, specific, and designed to reduce patterns of tension and subluxation so the nervous system has a better opportunity to regulate and adapt.
And I want to make something really clear here.
The goal is not to make your child stop being sensitive.
We are not trying to change who they are.
We are trying to give their nervous system more capacity.
That might first look like recovering from a meltdown in ten minutes instead of an hour.
It might look like walking into school without becoming completely overwhelmed.
It might be tolerating a haircut, wearing a few more types of clothing, sleeping more consistently, handling a noisy room better, or simply being able to experience frustration without immediately going over the edge.
Those are big neurological wins.
Sensory processing happens through the nervous system.
And when we understand how your child’s nervous system is functioning, we can stop guessing and start building support around what your child actually needs.
