Pelvic Floor Chiropractic Through A Nervous System Lens

The Shoulder–Pelvic Floor Connection: A Nervous System Lens on Pelvic Floor Health

By Dr. Don MacDonald & Brandi MacDonald | The Informed Chiropractor | Edmonton, Alberta

If you have ever wondered why pelvic floor symptoms can feel “bigger than the pelvis,” you are not imagining it.

One of the most common patterns we see in practice is this: people come in thinking they have a pelvic floor issue, but their body is also carrying tension through their ribs, breathing mechanics, jaw, neck, and shoulders. Or they come in for shoulder problems and later realize their pelvic floor has been quietly working overtime for years.

This is exactly why Brandi MacDonald and I created our Shoulder–Pelvic Floor Connection seminar. It is built for chiropractors, but the message applies to real humans living real life too.

Because pelvic floor health is not just a muscle issue. It is a whole-nervous-system experience.

Pelvic Floor Health Is Not Just Local

The pelvic floor is part of a pressure system.

It responds to breathing.
It responds to posture.
It responds to stress.
It responds to how safe the nervous system feels.

When your system is under chronic load, the body will often create stability wherever it can. Sometimes that stability shows up as gripping in the pelvic floor. Sometimes it shows up as rib restriction. Sometimes it shows up as shoulder tension, shallow breathing, or a diaphragm that is not moving well.

And when those pieces are not working together, the pelvic floor can become the “last line of defense.”

Why the Shoulder and Pelvic Floor Are Connected

A simple way to think about it is this:

The pelvis and the shoulders are both stability hubs.
They help organize posture, balance, and movement in a world that is constantly demanding output.

When the nervous system senses threat (physical, chemical, emotional, or sensory), the body often chooses a strategy:

Hold
Brace
Guard
Get rigid
Go quiet
Or swing between “on” and “off.”

That strategy can show up in the pelvic floor and the shoulder complex.

And if your breathing mechanics are compromised, the pressure system changes. The pelvic floor can begin to compensate. The ribs can stiffen. Neck and shoulder tone can rise. The body is trying to stay safe, not trying to frustrate you.

A Polyvagal Lens: Why Safety Changes Everything

We teach and practice through a Polyvagal lens because it gives language to what chiropractors see every day.

When a person feels safe, their nervous system has more capacity.
When capacity rises, the body can unwind patterns it has been gripping for years.
When the body unwinds, function improves.

Pelvic floor health often improves when the nervous system shifts out of chronic defense.

This does not mean pelvic floor symptoms are “all in your head.” It means the nervous system is the master organizer of muscle tone, breathing patterns, and tension strategies.

And that matters, because pelvic floor issues are often connected to:

Persistent stress and over-responsibility
Breathing pattern changes
Rib cage stiffness and poor diaphragm motion
Postural compensation
Past injuries
A system that has been “bracing” for a long time

What Chiropractic Can Do in This Conversation

Pelvic Floor Chiropractic care is not pelvic floor physiotherapy.

But chiropractic care can influence the system in which the pelvic floor resides.

When the spine, ribs, cranial base, and breathing mechanics improve, the nervous system receives different input. When the nervous system gets different input, tone can change. When tone changes, patterns of bracing can soften.

That is why we teach chiropractors how to adjust in a way that supports better neurological regulation, not just better mechanics.

And it is why people often report changes that they did not expect, such as:

easier breathing
less tension in the hips and low back
improved sense of ease after care
posture changes
improved awareness of pelvic tension
less “clenching” through the day

What We Taught in the Shoulder–Pelvic Floor Connection Seminar

This seminar was built around a clinical reality: you can’t separate the pelvic floor from the pressure system, and you can’t separate the pressure system from the nervous system.

In our training, we focused on:

Understanding how pelvic floor tension can be a protective strategy
recognizing patterns that link ribs, diaphragm, shoulder tone, and pelvic floor load
assessing global tone and regulation, not just symptoms
Adjusting with cues of safety so the system can receive the input
practical ways to create better outcomes without forcing change

A major theme was simple: small changes in how you assess and adjust can create massive changes in outcome.

For Chiropractors: Why This Matters Clinically

If you are a chiropractor, pelvic floor concerns will show up in your practice whether patients say the words or not.

The shoulder–pelvic floor pattern is often sitting underneath:

chronic low back tension
persistent hip tightness
breathing restriction
rib stiffness
Headaches and neck tension are tied to global tone
recurring “stress injuries.”
patients who don’t hold changes well

When you start seeing these patterns through a regulation-first lens, the conversation changes. Your care plans get cleaner. Your outcomes get more consistent. And your patients feel more understood.

For Practice Members: What To Do If This Feels Like You

If pelvic floor issues are part of your story, start here:

Notice your breathing. Is it shallow? Restricted? High in the chest?
Notice your shoulders. Are they always “on”?
Notice your pelvis. Is it always braced, tucked, clenched, or guarded?
Notice stress load. Not just big stress, but daily micro-stress.
Get assessed by providers who understand the whole system.

Pelvic floor health is often a team approach. Chiropractic may be one piece. Pelvic floor physio may be another. Strength training, breathing work, and stress capacity work may matter too.

But the biggest shift is this: stop treating the pelvis as if it were isolated.

Neuroception Shapes Patient Outcomes

One of the most useful ideas from polyvagal theory for a chiropractor is neuroception — the nervous system’s constant, below-conscious scanning for cues of safety or danger. A patient’s pelvic floor does not respond only to what you do with your hands. It responds to what their system detects in the room.

When the body detects danger, the protective response can include:

muscles guarding and bracing, including the pelvic floor
breathing becoming shallow, restricted or held
pain and sensitivity increasing
healing slowing down
movement becoming restricted

When the body detects safety, the shift can include:

muscle tone normalizing
breathing deepening and easing
pain decreasing
movement improving
healing being supported

Chiropractors who understand neuroception can improve outcomes by changing how they communicate, how they touch and how they set up their clinical environment — before they ever change a technique.

Breathing, Fascia and the Pelvic Floor: A Connected System

The pelvic floor works in coordination with the diaphragm. As you inhale, the diaphragm descends and the pelvic floor gently lengthens; as you exhale, they recoil together. When breathing patterns change — shallow chest breathing, breath holding, bracing through the ribs — the pelvic floor feels it.

Poor breathing habits can contribute to:

increased pelvic floor tension
reduced spinal stability
neck and shoulder tightness
low back discomfort
altered movement strategies

Fascia connects everything. The pelvic floor is linked through continuous fascial networks to the spine, the diaphragm, the hips, the abdomen, and even the neck and jaw. Tension or restriction in one area can influence the others — which is why a pelvic floor concern can show up alongside jaw tension, neck tightness or rib stiffness, and why working only at the pelvis sometimes misses the bigger picture.

Helping patients understand that the pelvic floor is not just muscles “down there” — it is part of a dynamic, living system that constantly adapts to how they breathe, move and respond to stress — often changes the whole conversation.

The Tailbone and Pelvic Floor Connection

Tailbone (coccyx) complaints are common in chiropractic practice, and they are closely tied to pelvic floor function. The pelvic floor muscles attach directly to the tailbone, so the two work as a unit: when one is under load, the other usually is too.

Persistent pelvic floor tension is often a sign that the nervous system is trying to create stability. When the deeper stabilizing system is not doing its job — or when the body has learned to brace through stress — the pelvic floor and tailbone region can become the place that holds everything together.

This is why tailbone pain that does not resolve with local care alone often needs a different kind of attention: addressing both the nervous system state and the mechanical load, rather than chasing the sore spot. When the system feels safer and moves better as a whole, the tailbone region often settles too.

Clinical Applications for Chiropractors

Bringing a pelvic floor lens into chiropractic does not require a new technique. It starts with how you observe and how you create safety:

Observe breathing patterns before you adjust — rate, depth, rib motion and where the breath goes.
Improve patient communication and language — explain what you are doing and why, in plain words.
Reduce unnecessary stress in the clinical environment — rushing, noise and unpredictability all register as threat.
Create a calm, welcoming space — your room, your pace and your presence are clinical tools.
Learn the signs of nervous system dysregulation — bracing, breath holding, startle, shutdown — and adjust your approach, not just your adjustment.
Look beyond structural findings to see the whole person — the story their body is telling matters as much as the imaging.

Start with curiosity rather than technique. Before you decide what to do, ask yourself: What is this person’s nervous system trying to protect right now? What story is their body telling? What would safety feel like for them? What happens if I slow down and observe before I act?

The chiropractor’s state matters too. If you want your patients to feel calm and safe, it helps to start with yourself. Take a breath before you walk into the room. Slow down your movements. Let your hands communicate ease rather than urgency. Your nervous system is part of the clinical environment.

Women’s Health: Pregnancy, Postpartum and Menopause

Pelvic floor concerns show up differently across a woman’s life. Pregnancy, postpartum recovery and menopause each change the demands on the pelvic floor — mechanically, hormonally and neurologically. A woman who is pregnant has different needs than a woman in menopause. A woman recovering from childbirth has different concerns than a woman preparing for it.

This is why listening comes before recommending. Useful questions include:

What has changed?
What is difficult right now?
What are your concerns?
What are your goals?

Pelvic floor care is often a team approach. Chiropractic may be one piece; pelvic floor physiotherapy may be another. Know when to refer, know how to collaborate, and make sure the team is communicating with each other. Patients benefit most when their providers are working together.

Women often feel their concerns are not fully heard. Listening first — before assessing, before explaining, before recommending — builds the trust that pelvic floor care depends on.

Communicating Safety in Pelvic Floor Care

Pelvic floor care requires good communication, because the pelvis is a vulnerable area and many patients carry stress, history or embarrassment around it. People can only relax when they feel safe — and people can only feel safe when they feel heard and respected.

Patients do not always need more information. They need clearer information: simple language, everything explained, no rushing, no assumptions. Phrases that build safety include:

“I’ll explain what we’re doing before we begin.”
“If something doesn’t feel right, tell me.”
“We can pause whenever you need to.”

And a question worth asking yourself regularly: How clear is my communication? How intentional are my actions? The answers shape outcomes as much as any adjustment.

Frequently asked questions

How are the pelvic floor and shoulders connected?
They are connected through posture, breathing mechanics, and nervous system tone. When the system is under stress, the body can brace globally, including the shoulders and the pelvic floor.

Can chiropractic help pelvic floor problems?
Chiropractic does not replace pelvic floor physiotherapy, but it may support pelvic floor function by improving spinal, rib, and nervous system input that influences breathing and muscle tone.

What is the polyvagal theory connection to pelvic floor health?
Polyvagal theory helps explain how safety and nervous system state influence muscle tone, bracing patterns, breathing, and the body’s ability to shift out of chronic defense.

Do I need special training to help patients with pelvic floor concerns?
Not to begin helping them in a broader sense. Understanding how the nervous system, breathing and posture influence pelvic floor function already changes how you assess and adjust. For internal or specialized pelvic floor work, refer to a trained pelvic floor physiotherapist — and consider that collaboration part of good care.

How does chiropractic support pelvic floor health?
Chiropractic does not replace pelvic floor physiotherapy. But by improving spinal motion, rib excursion, breathing mechanics and nervous system regulation — and by creating safety in the clinical encounter — chiropractic care can influence the system the pelvic floor lives in.

What should I do if a patient has pelvic floor concerns?
Start by listening. Create safety through clear communication and choice. Observe breathing and global tone. And build a referral relationship with a pelvic floor physiotherapist you trust, so the patient gets the right care at the right time.
