If you experience low back pain, you probably don’t immediately think about your pelvic floor.
You may assume your back pain is coming from your spine, muscles, posture, an old injury, or simply sitting too much. And sometimes, those things are absolutely part of the picture.
But your pelvic floor and low back are more connected than you might realize.
The pelvic floor is part of a larger system of muscles that helps stabilize your pelvis, manage pressure, support movement, and coordinate with your breathing. When one part of this system isn’t functioning well, other areas may compensate.
For some people, pelvic floor dysfunction and low back pain can occur together.
That doesn’t mean your pelvic floor is necessarily the cause of your back pain. Instead, it means there may be a relationship worth exploring.
If you’re experiencing both pelvic symptoms and low back pain, pelvic floor therapy may be one piece of understanding the bigger picture.
What Does the Pelvic Floor Have to Do With Your Back?
Your pelvic floor sits at the bottom of your pelvis, while your abdominal and back muscles help surround and support your trunk.
Together with your diaphragm, these muscles contribute to what is sometimes referred to as your body’s core system.
Your Core Is More Than Your Abdominal Muscles
When people hear the word “core,” they often think about their abdominal muscles.
But effective core function involves multiple structures working together, including:
- The diaphragm
- Abdominal muscles
- Back muscles
- Pelvic floor muscles
- Muscles around the hips and pelvis
These muscles don’t work independently.
They coordinate during breathing, walking, lifting, bending, running, coughing, sneezing, and many other everyday movements.
When that coordination changes, you may notice symptoms in more than one area.
How Are the Pelvic Floor and Low Back Connected?
The pelvis provides an important connection between your lower back and pelvic floor.
The pelvic floor attaches within the bony structure of the pelvis, and its function is influenced by the position and movement of the pelvis, hips, abdomen, and spine.
Your nervous system also plays an important role in coordinating these muscles.
Pressure Management Plays a Role
Every time you breathe, lift something, cough, sneeze, or strain, pressure changes within your abdomen.
Your diaphragm, abdominal muscles, pelvic floor, and back muscles respond to these changes.
When this system coordinates effectively, pressure can be distributed throughout your body.
When coordination is altered, you may compensate by overusing certain muscles or holding tension in others.
What Does This Look Like in Everyday Life?
Imagine lifting a heavy box.
Your body may naturally brace your abdominal muscles, coordinate your breathing, engage your back and hip muscles, and recruit your pelvic floor.
Now imagine that you’re holding your breath, gripping your abdominal muscles, or tightening your pelvic floor excessively every time you lift.
Over time, your movement strategy may become less efficient.
That doesn’t automatically mean you’ll develop back pain, but it demonstrates how different parts of your body contribute to movement and pressure management.
Can Pelvic Floor Dysfunction Cause Low Back Pain?
This is an important question, and the answer isn’t as simple as yes or no.
Pelvic floor dysfunction does not automatically cause low back pain.
Low back pain can have many different contributors, including muscular strain, joint irritation, disc-related conditions, nerve involvement, injuries, activity changes, and other medical conditions.
However, pelvic floor dysfunction and low back pain can occur together, and in some people they may share underlying movement, muscle, or nervous system factors.
The Pelvic Floor Can Become Overactive
One example is an overly tense or overactive pelvic floor.
Some people respond to pain, stress, injury, or repeated pressure by holding tension in their pelvic floor muscles.
Instead of contracting and relaxing as needed, the muscles may remain partially contracted for extended periods.
An overactive pelvic floor may be associated with symptoms such as:
- Pelvic pain
- Low back discomfort
- Hip or buttock pain
- Tailbone pain
- Pain with sexual activity
- Difficulty relaxing to urinate
- Constipation or difficulty relaxing during bowel movements
- Urinary urgency
- A feeling of pelvic tension or pressure
Not everyone with these symptoms has an overactive pelvic floor, but the pattern can be worth evaluating.
What If Your Pelvic Floor Is Weak?
The opposite can also occur.
If the pelvic floor muscles have difficulty generating or maintaining appropriate support, other muscles may compensate.
This doesn’t necessarily mean your back muscles become weak or injured. Instead, the way you coordinate your trunk and pelvis during movement may change.
Weakness Isn’t Always the Problem
One of the most common misconceptions about pelvic floor health is that every pelvic floor problem comes down to weakness.
Pelvic floor muscles need to be able to:
- Contract
- Relax
- Lengthen
- Coordinate with breathing
- Respond to changes in pressure
- Work with the rest of the body during movement
A muscle can be strong but poorly coordinated.
It can also be tight and still lack functional strength or endurance.
Why More Kegels Aren’t Always the Answer
If someone has low back pain and pelvic floor symptoms, it can be tempting to assume they simply need to strengthen their pelvic floor.
But doing more Kegels isn’t necessarily appropriate for everyone.
If the pelvic floor is already holding excessive tension, repeatedly contracting it may not address the underlying issue.
This is why an individualized pelvic floor evaluation can be helpful.
How Your Hips May Connect the Picture
Your hips, pelvis, and lower back work closely together during movement.
Limited hip mobility, weakness, pain, or changes in movement mechanics can influence how your pelvis and low back move.
Your pelvic floor may also respond to these changes.
Why Hip Strength and Mobility Matter
Activities such as walking, running, squatting, lifting, and climbing stairs require coordinated movement between the hips, pelvis, and spine.
Your pelvic floor contributes to this system, but it isn’t working alone.
That’s why a pelvic floor evaluation may include looking at:
- Hip strength
- Hip mobility
- Pelvic movement
- Core coordination
- Breathing
- Balance
- Squatting
- Walking
- Other functional movements
The Goal Is to Look at the Whole Person
Rather than asking, “Is my pelvic floor weak?” a better question may be:
“How are all of these systems working together?”
That broader perspective can help identify factors contributing to symptoms and guide a more individualized treatment plan.
Who Might Benefit From Pelvic Floor Therapy for Low Back Pain?
Pelvic floor therapy may be worth considering if you have low back pain along with pelvic health symptoms.
Consider an Evaluation If You Also Experience:
- Urinary leakage
- Urinary urgency or frequency
- Constipation
- Difficulty emptying your bladder or bowels
- Pelvic pressure
- Pelvic pain
- Tailbone pain
- Pain with sexual activity
- Postpartum changes
- Symptoms following pelvic or abdominal surgery
- Difficulty returning to exercise
- Pain or tension around your hips or pelvis
You don’t need to have all of these symptoms.
Even if you’re primarily concerned about your back, discussing pelvic health with a qualified provider may help determine whether there is a connection worth addressing.
What Happens During a Pelvic Floor Therapy Evaluation addressing low back pain?
A pelvic floor therapy evaluation isn’t simply a series of Kegel exercises.
Your therapist will first want to understand what’s happening and how your symptoms affect your daily life.
Your Evaluation May Include:
- Discussion of your symptoms and medical history
- Assessment of posture and movement
- Breathing assessment
- Core coordination
- Hip strength and mobility
- Functional movement
- Pelvic floor muscle function
- Muscle tension and relaxation
- Your individual goals
An internal pelvic floor assessment may be appropriate for some people, but it isn’t automatically necessary.
You Are in Control of Your Care
Pelvic health can involve sensitive topics, and your comfort matters.
Your therapist should explain the purpose of any assessment or treatment, answer your questions, and obtain your consent.
