Pelvic Floor Muscle (PFM) Dysfunction

The Impact of Pelvic Floor Muscle (PFM) Dysfunction

  • When the pelvic floor muscles are not working properly, the muscles cannot purposefully (aka voluntarily) nor reflexively (aka involuntarily) contract and relax correctly. 
  • The fast-twitch fibers become predominant, and the slow-twitch endurance fibers lose their power and influence.
  • The PFMs become underactive or “loose and weak” or they become overactive or “short and tight and weak.” 
  • The PFM can also become uncoordinated so that they contract when they are supposed to relax leading to bladder, bowel, and pain problems.
  • The PFMs are skeletal muscles located inside of the pelvis. The PFMs attach from the pubic bone in front to the tailbone (coccyx) in the back, and they attach to the deep hip rotator muscles (obturator internus muscles) along the side walls of the pelvis.

How Pelvic Tilts Lead to PFM Dysfunction

A misaligned pelvis disrupts the foundational alignment needed for coordinated pelvic floor muscle function. When the pelvis tilts or rotates, it alters joint positioning and nerve signaling, causing muscles to overactivate, under-recruit, or fire asymmetrically. This imbalance can lead to dysfunctions like incontinence, pain, prolapse, or difficulty with bowel and bladder regulation.

Academic and Clinical References Supporting the Importance of Pelvic Alignment

  1. "Pelvic Floor Function and Dysfunction" by Kari Bø et al.
    • This textbook discusses how posture and breathing impact pelvic floor length-tension relationships.
    • Notes the relationship between lumbar spine position (posterior vs. anterior tilt) and pelvic floor tone.
  2. "The Pelvic Floor" in Clinical Anatomy by Richard Drake et al.
    • Offers a detailed breakdown of the origin/insertion of pelvic floor muscles, which you can use to infer how tilting affects them biomechanically.
  3. Diane Lee & Paul Hodges' work on core stability and pelvic-lumbar dynamics
    • Their research explains how pelvic orientation changes the muscular tension of core and pelvic floor structures.
  4. Pelvic Floor Physical Therapy Sources (e.g., Herman & Wallace Institute, APTA resources)
    • Many clinical guides from these groups discuss how poor posture (like chronic posterior tilt) can lead to hypertonicity in the front/anterior pelvic floor and inhibition of posterior muscles.
  5. Biomechanics of Human Movement – David A. Winter
    • While this book doesn't name pelvic floor muscles specifically, it lays out how postural alignment alters muscle resting length and tension.

Fluidity Rx Trains Users into a Neutral Pelvis

A neutral pelvis restores the structural foundation needed for balanced pelvic floor muscle engagement, allowing for proper contraction and relaxation without compensation. This alignment improves nerve signaling, joint stability, and pressure regulation across the core, helping resolve issues like incontinence, pain, and prolapse. By supporting symmetrical muscle activation and fascial glide, a neutral pelvis creates the conditions for reflexive, resilient pelvic floor function.

*All PFM’s are at a neutral length equaling optimal function.

Your Core The Inner Unit

The Inner Unit automatically activates to:

  • Control intra-abdominal pressure (the pressure in the abdomen between the lungs and the pelvic floor)
  • Stabilize the spine and pelvis before you move your arms and/or legs during movement

When intra-abdominal pressure (IAP) is functioning optimally, It

  • Helps Stabilizes the Spine and Core
  • Coordinates Breathing and Movement
  • Enhances Strength and Ensures Coordinated Force Distribution from the Torso to the Limbs.
  • Supports Pelvic Floor and Organ Function.
  • Promotes Postural Alignment

“Fluidity Rx provides the optimal method for not only pelvic floor muscle training but also to incorporate the pelvic floor muscles functionally into optimal movement patterns. Fluidity Rx training maximizes a person’s ability to modulate intra-abdominal pressure by the precise training of co-contraction of the pelvic floor with the abdominal, spine, and diaphragm muscles for inner core muscle strength.”

Women with Stress Urinary Incontinence are 17 times more likely to heal if they strengthen their pelvic-floor muscles [1]

Fluidity Rx is for everyone – men and women. It uses precise verbal instructions and movements in a neutral spine position—the optimal position for PFM contraction and relaxation—to activate the PFM and train both fast and slow twitch muscle fibers, maintaining the ideal proportion of each fiber type.

The program includes the following videos:

Note: If you cannot engage your pelvic floor initially, it may take about two weeks of using the Ball Video, Standing Pelvic Floor Muscle Training Video, and Breath Video, three times a week, to progress to the Beginner, Intermediate, and Advanced Videos. This protocol is optimal for all types of pelvic floor dysfunction and both sexes.
