Most people who come to our Lakewood Ranch office carrying chronic lower back pain have already done a good amount of the right things. A round of physical therapy. An imaging scan that showed something, or showed nothing. Core exercises. Maybe a different mattress. The pain improved somewhat, then came back. Possibly in the same spot. Possibly worse than before.
There is a structural contributor that rarely makes it into the conversation: the pelvic floor. This group of muscles forms the literal base of the pelvis, running from the pubic bone in front to the coccyx in back. When it is too weak or chronically tight, it changes how the lumbar spine manages load every single day. That change, sustained over months or years, is enough to keep back pain from fully resolving regardless of what else you try.
This is not a niche issue. It shows up in patients across a wide range of ages and presentations. And because neither an X-ray nor an MRI shows pelvic floor muscle tone, the connection often gets missed entirely.
What the Pelvic Floor Actually Does
The pelvic floor is a hammock of muscles and connective tissue that spans the base of the pelvis. It connects from the pubic symphysis in front to the coccyx in back, and from one ischial tuberosity (sit bone) to the other. Most people learn that it controls bladder and bowel function. That is true, but it is only part of the picture.
The pelvic floor is also a key load-bearing structure for the lumbar spine. It works with the diaphragm (your primary breathing muscle), the deep abdominal muscles (particularly the transverse abdominis), and the lumbar multifidus to create what spine researchers call intra-abdominal pressure. That pressure acts as a natural internal brace during lifting, bending, and any movement that puts axial load through the spine.
When the pelvic floor is doing its job, the lumbar spine gets meaningful support from below on every load cycle. When it is not, the discs, facet joints, and spinal ligaments compensate by absorbing forces that were supposed to be distributed more broadly. Over time, that compensation is what you feel as pain.
The Pressure System Your Spine Depends On
Picture a cylinder with four walls. The lid is the diaphragm. The floor is the pelvic floor. The walls are the deep abdominals and multifidus. When this canister pressurizes together during movement, the lumbar spine stays stable. When any one part of it fails to contribute, the rest of the system has to compensate.
Two different patterns of pelvic floor dysfunction create two different problems in the lumbar spine.
A pelvic floor that is too weak fails to pressurize from below. This leaves the lumbar discs and facet joints picking up load that the pressure canister is supposed to absorb. The result is often a diffuse, achy lower back that worsens throughout the day as fatigue accumulates.
A pelvic floor that is chronically tight creates a different problem. A hypertonic (too-tight) pelvic floor changes the resting position of the sacrum and coccyx, often pulling them into a position that compresses the L4-L5 and L5-S1 disc spaces. Many patients in this pattern present with localized pain right at the belt line that worsens with extension (bending backward) and with prolonged sitting. For patients whose disc is significantly involved, we sometimes discuss non-surgical spinal decompression as a way to reduce intradiscal pressure while the structural drivers are being addressed.
Who Is Most Likely to Have This Pattern
Pelvic floor dysfunction is not exclusive to women, though the circumstances that trigger it differ by population.
In women, the most common contributors are pregnancy and vaginal delivery, perimenopause (when falling estrogen reduces muscle tone throughout the pelvic floor), and long-term sedentary work with no coordinated pelvic floor engagement. Women who have had multiple deliveries or a prolonged second stage of labor are at particularly high risk for lasting pelvic floor changes that contribute to back pain years later.
In men, pelvic floor problems are most common after prostate surgery or radiation, with chronic constipation involving years of straining, and in those who combine anterior pelvic tilt (a common desk posture pattern: see our post on anterior pelvic tilt and lower back pain) with years of sedentary work. The hypertonic pattern in particular affects men who hold significant muscular tension in the hips and pelvic girdle.
In both sexes, weak gluteal muscles tend to develop alongside pelvic floor dysfunction. The gluteus maximus and pelvic floor share fascial connections and tend to underfunction together. Patients who have already been told they have glute amnesia contributing to their back pain may find the pelvic floor component is part of the same pattern.
Signs That the Pelvic Floor May Be Contributing to Your Back Pain
None of these individually confirms pelvic floor dysfunction. But the presence of several alongside persistent lower back pain that has not responded to standard care is a pattern worth bringing to a provider.
- Leaking urine when coughing, sneezing, laughing, or jumping
- Strong urgency to urinate that is difficult to postpone
- A feeling of heaviness or downward pressure in the pelvis
- Pain at the tailbone or deep in the buttocks (not sciatica-pattern pain radiating into the leg)
- Back pain that varies meaningfully with the menstrual cycle in women
- Back pain that is significantly worse in the second half of the day
- Persistent tightness in the hip adductors (inner thigh) that does not release with stretching
- Lower back or pelvic pain that worsens with prolonged sitting but does not fully resolve with movement
- Back pain that has not responded as expected to core stability exercises
That last point is clinically useful. Patients in this pattern sometimes report that core exercises make their pain worse, or do nothing. This makes sense: if the pelvic floor is not contributing to the canister, loading the top of it (the abdominals) without the bottom engaged can actually increase compressive forces on the lumbar spine.
What the Structural Evaluation Looks For
When a patient comes to us with back pain that has not fully resolved, the evaluation goes beyond a single region. The goal is to understand where load is being mismanaged and why.
A thorough structural evaluation for this pattern includes:
- Range of motion testing for the lumbar spine, hips, and sacroiliac joints
- Assessment of pelvic position: anterior or posterior tilt, lateral imbalance, sacral rotation
- Hip flexor, gluteal, and adductor strength testing
- Sacroiliac joint provocation tests to identify SI joint involvement
- Leg length assessment and assessment of foot arch collapse that may alter pelvic load
- Neural tension testing to distinguish a sciatica pattern from nerve root compression versus referred pain from the lumbar joints or pelvic floor itself
The structural picture that emerges often shows the lumbar spine working in isolation, without meaningful support from the hips or pelvic floor. Dr. Banman has treated back pain in Lakewood Ranch for over 23 years. The pattern of a mechanically stressed lumbar spine with underperforming pelvic stabilizers is one we evaluate routinely.
What Chiropractic Care Addresses in This Pattern
Chiropractic care does not directly rehabilitate pelvic floor muscles. That work belongs to a licensed pelvic floor physical therapist. But the spinal and structural component of this pattern is squarely within chiropractic scope, and addressing it often determines whether pelvic floor rehabilitation actually works.
A pelvic floor that is trying to do its job against a pelvis that is mechanically restricted or misaligned is working against a fixed disadvantage. The specific goals of structural care in this context are:
- Restoring normal joint mobility at the sacroiliac joints, lumbar spine, and hips so the pelvis is in a position where the pelvic floor can actually engage
- Reducing protective muscle guarding that develops around chronically loaded facet joints at L4-L5 and L5-S1
- Addressing spinal movement restrictions that alter nerve signaling to the pelvic region
- Providing movement coaching that helps patients load the lumbar spine more evenly during daily activity
Many patients report that once the structural restrictions in the lumbar spine and pelvis are corrected, exercises they had been doing for months without effect finally start working. The mechanics are in the right position for the pelvic floor to contribute.
When Pelvic Floor PT Becomes Part of the Plan
Not every back pain patient needs pelvic floor physical therapy. But if you identify with several of the signs listed above, and if standard care has only partially worked, a pelvic floor assessment from a licensed pelvic floor PT is a reasonable next step.
The approaches are genuinely complementary. Structural chiropractic care gets the spine and pelvis into a mechanically sound position. Pelvic floor PT retrains the muscles themselves. Neither fully substitutes for the other when both components are involved.
In our experience evaluating patients with this combined pattern, the improvement that comes from working both the structural and the muscular sides tends to be more stable than addressing either one in isolation. The structural side determines whether the muscular side has any real ground to stand on.
At our office, we coordinate with pelvic floor physical therapists in the Lakewood Ranch and Bradenton area when the clinical picture points that direction. The referral is part of the evaluation, not an afterthought.
What to Do If This Sounds Familiar
If you have been managing lower back pain that keeps coming back, and any of the patterns above match your experience, the starting point is a thorough structural evaluation rather than another round of the same approach.
Steps worth taking now:
- Note what makes your pain better and worse. Specific movement patterns (worse with sitting, worse after standing, changes with lifting) tell the evaluating provider more than imaging does.
- Track whether symptoms change around your menstrual cycle. If there is a hormonal component, that is clinically relevant information.
- Mention any bladder urgency, pelvic heaviness, or incontinence at your appointment. Many patients treat these as separate issues and do not mention them. They are not separate.
- Ask specifically whether a pelvic floor PT evaluation would be appropriate for your presentation. If no one has raised this and your back pain has been ongoing, it is a reasonable question.
At Spine and Wellness Center Lakewood Ranch, Dr. Banman evaluates the lumbar spine, sacroiliac joints, and hips as a system. If the evaluation suggests a pelvic floor component, we address the structural side directly and coordinate referral for the muscular side.
