Lower Back Pain and the Pelvic Floor: Is There a Connection?

The Link Most People Miss

Lower back pain is one of the most common complaints in healthcare — affecting up to 80% of adults at some point in their lives. Most people assume it's a spine problem, a muscle strain, or the result of poor posture. What far fewer people know is that the pelvic floor is frequently a contributing factor — and addressing it can make a significant difference.

How the Pelvic Floor and Lower Back Are Connected

Your pelvic floor is part of your deep core system — a group of four muscles that work together to stabilize your spine and pelvis: the diaphragm, transverse abdominis, multifidus, and pelvic floor. These muscles are designed to co-activate automatically during movement to protect the spine.

When the pelvic floor is weak, overactive, or poorly coordinated, the entire deep core system is affected. The spine loses some of its dynamic stabilization, and other muscles — including the superficial back muscles — have to compensate. Over time, this compensation leads to muscle fatigue, altered movement patterns, and chronic lower back pain.

The Research Connection

Multiple studies have found significant associations between pelvic floor dysfunction and lower back pain:

• Women with stress urinary incontinence have higher rates of lower back pain than continent women
• Pelvic floor muscle dysfunction is more common in people with chronic lower back pain than in pain-free controls
• Treating pelvic floor dysfunction has been shown to improve lower back pain outcomes in several clinical studies
• Pregnancy-related pelvic girdle pain — which affects up to 20% of pregnant women — is closely linked to pelvic floor and deep core dysfunction

Signs That Your Lower Back Pain May Have a Pelvic Floor Component

• Lower back pain that worsens during or after prolonged standing or walking
• Back pain that coincides with bladder or bowel symptoms
• Pain that started or worsened during pregnancy or postpartum
• Back pain accompanied by hip pain or pelvic girdle pain
• Pain that hasn't responded to standard back treatments (massage, chiropractic, etc.)

What to Do About It

Address the Pelvic Floor Directly

If your lower back pain has a pelvic floor component, treating the pelvic floor is essential — not optional. This means targeted pelvic floor training to restore strength and coordination, combined with deep core rehabilitation.

The SculptHer PelviRestore provides structured pelvic floor training that supports the entire deep core system — not just bladder control. With over 351 verified reviews, many users report improvements in core stability and reduced back discomfort alongside their pelvic floor gains.

Restore Breathing Mechanics

Diaphragmatic breathing is the foundation of deep core function. If you habitually breathe into your chest rather than your belly, your deep core system — including your pelvic floor — is not functioning optimally. Restoring proper breathing mechanics is often the first step in deep core rehabilitation.

See a Pelvic Floor Physiotherapist

For persistent lower back pain with a suspected pelvic floor component, a pelvic floor physiotherapist can assess the relationship between your pelvic floor function and your back pain, and develop a targeted treatment plan. This is particularly valuable for postpartum women and those with chronic back pain that hasn't responded to standard treatment.

Avoid Exercises That Worsen Both

High-load exercises like heavy deadlifts, sit-ups, and certain yoga poses can worsen both pelvic floor dysfunction and lower back pain if the deep core system isn't functioning properly. Build the foundation first.

The Bottom Line

If you have chronic lower back pain — especially if it's accompanied by any pelvic floor symptoms — the pelvic floor is worth investigating as a contributing factor. It's an often-overlooked piece of the puzzle that can make a significant difference when addressed.
