C-Section and Sensory Processing Disorder

Episode 150, Experience Miracles Podcast | Host: Dr. Tony Ebel, DC, CACCP, Pediatric Chiropractor & Founder of PX Docs | Published: October 24, 2024 | Duration: ~38 min

Key Takeaways

• A meta-analysis found that 80% of children born via C-section develop sensory processing disorder or significant sensory challenges, and Dr. Tony Ebel reports seeing an even higher connection in 17 years of clinical practice, with 80–90% of sensory kids having a birth intervention in their history.
• C-section delivery puts abnormal mechanical stress on an infant’s upper neck, skull, and cranial system, creating subluxation at the occiput, C1, C2, and upper thoracic spine, the exact regions that control the sensory motor relay, vestibular processing, proprioception, and vagus nerve communication.
• At the root of sensory processing disorder is a two-part neurological formula: decreased proprioception from upper cervical and thoracic subluxation, which then opens the gate (gate theory) for increased nociception, constant, irritating sensory input the brain cannot filter or quiet.
• Neurosensory issues end up in the gut, they don’t start there. Gut-based interventions (diet, supplements) can support healing, but the root cause of sensory challenges following C-section is neuro-biomechanical: it lives within subluxation, not nutrition.
• Neuro-tonal chiropractic adjustments combined with movement therapy, swimming, climbing, cross-body activities, time in nature, are the most direct way to calm sensory overload, reduce subluxation, and restore normal proprioceptive signaling to the brain.

Does a C-Section Cause Sensory Processing Disorder?

C-section delivery is the most common birth intervention linked to sensory processing disorder, and the neurophysiological pathway explaining why is rarely discussed by other providers. A meta-analysis found that 80% of children born via C-section develop sensory challenges, a number consistent with what Dr. Tony Ebel has observed across 17 years of clinical practice. Preterm and early-birth infants show an even higher rate: 84%.

The mechanism begins at delivery. During a C-section, the surgeon must grip the infant by the head and neck to extract them, a process involving traction, twisting, and pulling that natural vaginal birth does not replicate. Mom’s pelvic floor muscles, nerves, and birth canal normally guide the baby through in a way that gently activates the upper thoracic spine. That activation doesn’t happen in a surgical delivery. The result is subluxation, dysfunction and misalignment, concentrated at the occiput (base of skull), C1 (Atlas), C2 (Axis), and the upper thoracic spine.

These are not random spinal regions. They house the sensory motor reflex relay, vestibular and proprioceptive pathways, and the vagus nerve communication superhighway. When they’re compromised from birth, the entire developmental sequence, latching, head control, tummy time, rolling, crawling, is built on a faulty foundation. And the sensory dysregulation that follows isn’t a gut problem or a behavioral problem. It’s a nervous system problem rooted in birth trauma.

The 80% Study: What It Found and What It Didn’t Explain [00:01:00 – 00:08:00]

Dr. Tony Ebel, DC, CACCP: All right, parents. Here we go. It’s the Ask Dr. Tony episode. This is the Experience Miracles podcast, and I’m your host, Dr. Tony Ebel, an expert in pediatrics, neurodevelopmental disorders, and drug-free nervous system-focused healthcare. On this weekly episode, I’ll be addressing the top questions on every parent’s mind.

For today’s Q&A episode, we’re going to talk about sensory processing disorder, and a study which is linked in the show notes. Not a huge study, not the biggest group of kids, but a study that has quite an alarming finding that neurosensory motor-wise makes sense to us. It found that 80% of kids born via C-section would end up, or did end up, with sensory processing disorder or sensory challenges. They also found that preterm or early birth kiddos had an 84% connection to sensory challenges.

When we posted this on Instagram, it came with a lot of engagement, and that engagement split three ways.

The first group was families who already put it together themselves: “My child had a tough birth and they were colicky from the beginning.” Colic is hypersensitivity. They don’t sleep well, they don’t calm well, they don’t soothe well. How is that different than a five-year-old in kindergarten who can’t stand fluorescent lights, can’t stand the tag on their shirt, can’t handle certain food textures or the noise of a classroom? Sensory challenges in a five-year-old, simplified, are the same neurosensory challenge as a colicky baby or a toddler having meltdowns.

The second group said, “Huh, that’s intriguing. Please tell me more.” Parents who, for the first time, thought: “Oh my goodness, could that be connected?”

Now let’s talk about the third camp, because they matter too. If your child was born via C-section and has no sensory issues, no neurological issues, that is genuinely great, and it’s to be celebrated. C-section is not a guaranteed sensory outcome. The Perfect Storm is multifaceted. Autism is multifaceted causation, not one thing. If you took Tylenol during pregnancy, it’s not a guaranteed autism outcome. If you had a C-section, it’s not a guaranteed sensory outcome.

What we know is this: if there’s C-section, there’s a higher risk on a percentage basis of sensory challenges. None of these cases is an absolute, not a single one of them is 100% of the time A will lead to B. That’s not how neurophysiology works. That’s not how health works. It is so complex, and that’s a good thing, because what it proves is that children are resilient and adaptable.

But the meta-analysis didn’t explain etiology, causation, or neurophysiology. They connected dots and stopped. That job falls to us here today.

“The perfect storm is a multitude. Autism is multifaceted causation, not one. So if you took Tylenol during pregnancy, it’s not a guaranteed autism outcome. If you had a C-section, it’s not a guaranteed sensory outcome.”

The Neuroscience of How C-Section Creates Subluxation [00:12:00 – 00:18:00]

C-sections, vacuum deliveries, and inductions all put excessive, abnormal mechanical stress on the infant’s upper neck and cranial system. They also create distortion (twisting) and distension (stretching) throughout the whole spine and neurospinal system.

Children born via C-section show much higher rates of subluxation, somatic dysfunction, where vertebrae and cranial structures aren’t aligned, moving, or functioning properly, concentrated at:

• Occiput (base of the skull)
• C1, or Atlas
• C2, or Axis
• Upper thoracic junction (the traps, shoulder blades, upper back)

These areas are not incidental. They house the key sensory motor reflex relay, the vestibular, proprioceptive, and vagus nerve communication superhighway. This is the region that must function optimally for a baby to latch, breastfeed, track movement, and begin the motor development sequence.

In a vaginal birth, mom’s pelvic floor muscles guide the baby through the birth canal and activate the upper thoracics. That activation doesn’t happen in a C-section. Instead, the upper thoracics never get that neuromotor “kick on” signal. So from the very first moment, the nervous system of a C-section baby is working against a compromised foundation.

It’s not about how the baby is delivered. It’s about how that delivery impacts the brain, the spine, the nerves, the muscles, and the sensory motor system, for life, until found and fixed.

“Neurosensory issues end up in the gut. They don’t start in the gut. Neurosensory healing can be improved with nutritional interventions, diet changes, getting rid of certain things, adding certain supplements, but its root isn’t nutritional. It’s neuro-biomechanical. It’s within subluxation.”

How Subluxation Derails Motor Development Step by Step [00:18:00 – 00:22:00]

After birth, babies have a clear developmental sequence: eat, sleep, poop, and then move. Specifically:

1. Hold their head and neck up (smooth and symmetrical, not stuck to one side)
2. Tolerate and love tummy time
3. Roll over
4. Sit up
5. Crawl

C-section kiddos are significantly more likely to have torticollis and plagiocephaly, and to struggle with every step of this sequence. Here’s why: the yanking and twisting of the upper neck during delivery leaves those muscles locked in hypertonicity and tension. They didn’t receive the upper thoracic activation from the birth canal. So when it’s time for tummy time, those nerves and muscles aren’t ready.

If they struggle with head and neck control and tummy time, they struggle to roll. If they can’t roll, sitting is harder. And critically, C-section kiddos often skip crawling entirely. Crawling is essential for calming and integrating the brain. Skipping it has downstream effects.

What’s left in the brain? Instead of receiving calming proprioceptive signals from the spine, the brain gets distorted, confusing, irritating signals, called nociception. At the heart of sensory processing disorder, you can break it down to this neurosensory formula:

Decreased proprioception (from subluxation) → Gate opens for increased nociception → Brain flooded with sensory noise it cannot filter

When you don’t have sensory challenges and you put on a thick shirt with a tag and heavy socks and stiff shoes, your tactile system initially registers all of it. But within moments, the brain says: “Not important. We have other things in the hierarchy.” You stop noticing the fabric, the tag, the stitches.

For a child with subluxation-driven sensory challenges, that filter doesn’t work. The nociceptive input is so loud, so constant, so relentless, the brain can’t turn it off. Every tag is a fire alarm. Every seam is unbearable. Sensory kids call shoes “foot coffins.”

What Sensory Overload Actually Feels Like [00:24:00 – 00:28:00]

Imagine you’re driving, you’ve memorized the route, you know exactly where you’re going, but your kids are in the back making noise, your husband’s asking about dinner, and the radio’s blasting. What’s the first thing you do? You turn down the radio. You say: “Quiet. I can’t think straight.”

You’re not actually “hearing where you’re going.” But the auditory noise is interfering with your ability to process your visual map. You instinctively reduce one sensory input to optimize the one you need most.

That’s a real-life version of sensory processing. We all have some degree of it, we wear noise-canceling headphones in coffee shops, we turn off the TV to have a serious conversation. The difference for sensory kids is the noise never turns off. The dial doesn’t budge.

C-section triggers dysregulated sensory motor input → subluxation → sympathetic dominance → dysautonomia → vagus nerve shutdown → brain filled with noise.

It’s basically like trying to live your entire life in the front row of a Metallica concert, all day, every day, with no headphones.

That’s why sensory kids melt down at the slightest transition. That’s why they can’t handle certain clothes or certain foods. That’s why they can’t fall asleep, you have to get out of the sensory sympathetic storm to fall asleep.

“C-section triggers this dysregulated sensory motor input that triggers subluxation, sympathetic dominance, dysautonomia. The vagus nerve gets shut down. The brain is filled with noise. It’s basically like trying to live life and you’re at a front row of a Metallica concert all day, every day with no headphones.”

How to Help: Neuro-Tonal Adjustments and Movement Therapy [00:28:00 – 00:34:00]

So, rounding third base, as we always promise. How do we help?

Neuro-Tonal Chiropractic Adjustments

The upper cervical, cranial, and upper thoracic areas are so subluxated, so full of sensory dysfunction and distortion, that they constantly flood the brainstem with noxious, noisy input. Neuro-tonal adjustments are exactly like taking the volume dial and turning it down.

Two types of adjustments serve different purposes:

• Calming, integrating adjustments, designed for kids stuck in sensory overdrive and sympathetic dominance. These quiet the raging, overloaded sensory storm. They’re gentle and reorganizing.
• Activating adjustments, designed to stimulate the suppressed vagus nerve and parasympathetic system. Many sensory kids have hypersensitivities and hyposensitivities. Both need to be addressed. Toning down the sympathetic and activating the parasympathetic are two distinct moves.

The result, when both are working together, is a nervous system that can finally start filtering sensory input the way it was designed to.

Movement, The Essential Second Layer

Even if you don’t have access to a PX Docs office, movement is the number one complementary intervention for sensory kids. What calms sensory processing challenges and helps a child heal from a C-section? Movement. Specifically:

• Swimming, cross-body integration, vestibular input, proprioceptive stimulation
• Climbing, activates postural muscles and cerebellar pathways
• Nature and grounding, barefoot proprioceptive input
• Martial arts, structured cross-body integration and reorganization
• Roughhousing and wrestling, heavy proprioceptive input, co-regulation with a parent
• Infant massage, available on YouTube; adds calming proprioception
• Trampolines, weighted blankets, sensory chairs, add proprioceptive input at home

A neuro-tonal chiropractic adjustment is the most potent, specific, deeply targeted proprioceptive input available, it overrides subluxation directly. OT, PT, and natural movement are helpful, but often not powerful enough to override a stuck subluxation on their own. That said, they are essential, especially for families still working toward chiropractic care or those adding support between adjustments.

Additional lifestyle factors: Reduce sugar and environmental toxins. Limit screens, they further overwhelm an already overloaded sensory system. Time outside simultaneously replaces screen time and adds the proprioceptive, integrating input sensory kids most need.

“The number one thing that calms sensory processing challenges and helps a child heal from C-section is, yes, chiropractic, but two: movement. Get them outside. Get them swimming. Get them climbing. Get them into nature.”

Frequently Asked Questions

Can a C-section cause sensory processing disorder in my child?

Research shows that 80% of children born via C-section develop sensory processing disorder or significant sensory challenges, with preterm babies showing an 84% rate. The mechanism is a neurophysiological one: C-section delivery puts abnormal mechanical stress on the infant’s upper neck and spine, creating subluxation at the occiput, C1, C2, and upper thoracic spine, the regions that control sensory motor processing, vestibular function, and vagus nerve communication. Not every C-section baby develops sensory challenges, but the risk is substantially elevated.

Why do sensory issues happen in the spine, not the gut?

Parents often try gut-based interventions first because gut symptoms are visible in sensory kids. But according to Dr. Tony Ebel, neurosensory issues end up in the gut, they don’t start there. Diet changes and supplements can support healing, but the root of sensory processing disorder following birth trauma is neuro-biomechanical: it lives in subluxation of the upper cervical and thoracic spine, not in nutritional deficiency. Addressing subluxation directly is what shifts the underlying nervous system dysfunction.

What does sensory overload actually feel like for a child?

Dr. Tony Ebel describes it as “living in the front row of a Metallica concert all day, every day, with no headphones.” When subluxation disrupts proprioception, the brain receives constant nociceptive (irritating, aggravating) sensory input it cannot filter. A child who melts down over clothing tags, food textures, noise, or transitions is not being dramatic, their nervous system genuinely cannot filter out sensory stimuli the way an unaffected nervous system does automatically.

Why do C-section babies often skip crawling, and does it matter?

C-section delivery leaves the upper neck muscles in hypertonicity and tension from the traction of delivery, and the upper thoracic spine never receives the neuromotor activation that the birth canal normally provides. This compromises the entire motor development sequence: head and neck control → tummy time → rolling → sitting → crawling. C-section babies frequently skip crawling, and crawling is essential for calming and integrating the brain. Skipping it has downstream consequences for sensory processing and neurological development.

Is chiropractic care or movement more important for sensory kids?

Both are needed, and they work differently. Neuro-tonal chiropractic adjustments are the most direct intervention, they target subluxation specifically and override it in a way that OT, PT, and general movement cannot fully replicate. But movement, especially swimming, climbing, cross-body activities, and outdoor play, is the most important complementary intervention. It adds proprioceptive input, activates cerebellar pathways, and begins integrating the sensory system between adjustments. For families without immediate access to a PX Docs provider, movement is the place to start.
