Pelvic floor

The pelvic floor is a complex system of muscles, fascia and ligaments that close the lower aperture of the true pelvis. These structures form a kind of "supportive platform" for pelvic organs such as the urinary bladder, uterus and rectum. In addition to its mechanical function, the pelvic floor plays an important role in maintaining continence, stabilizing posture and regulating intra-abdominal pressure. Its proper function requires harmonious cooperation of the muscular, nervous and fascial systems, and disorders in this area can lead to significant clinical problems in both women and men.

Pelvic floor – structure

The pelvic floor is composed of three musculofascial layers that form a functional and anatomical whole. The most important element of this structure is the levator ani muscle (levator ani), which together with the coccygeal muscle forms the pelvic diaphragm.

The levator ani muscle is composed of:

puborectalis muscle,
pubococcygeus muscle,
iliococcygeus muscle.

The superficial layer includes muscles responsible for sphincteric and sexual functions, such as:

bulbospongiosus muscle,
ischiocavernosus muscle,
superficial transverse perineal muscle.

The middle layer (urogenital diaphragm) contains structures supporting the urethra and the genital organs.

The entire structure is stabilized by:

pelvic fascia,
ligaments (e.g., the uterosacral ligament),
the nervous system (mainly the pudendal nerve).

The structure of the pelvic floor provides both flexibility and the capacity for adaptation – particularly important during childbirth, micturition, and defecation.

Pelvic floor – functions

The pelvic floor performs multifaceted functions that go beyond a simple supportive role. Its action is dynamic and is closely linked to the work of the respiratory diaphragm and the deep trunk muscles.

The most important functions include:

1. Support of the pelvic organs

It provides stabilization of the bladder, uterus and rectum, preventing their descent or prolapse.

2. Control of urinary and fecal continence

The pelvic floor muscles cooperate with the sphincters, enabling voluntary maintenance of continence.

3. Regulation of intra-abdominal pressure

They interact with the diaphragm and the abdominal muscles, stabilizing the spine and participating in mechanisms of the abdominal press.

4. Sexual function

They affect the quality of sexual sensations and the proper blood supply to the genital organs.

5. Role in childbirth

They stretch, allowing the fetus to pass through the birth canal.

Disorders of these functions can lead to urinary incontinence, prolapse of the reproductive organs, pelvic pain, or sexual dysfunction.

Pelvic floor – weakness

Weakening of the pelvic floor muscles means a loss of their tone, strength and ability to respond properly to changes in intra-abdominal pressure. It is a functional problem that often develops gradually and remains unrecognized for a long time.

The most common symptoms of weakening include:

stress urinary incontinence (e.g. during coughing, sneezing),
a feeling of heaviness or "pulling" in the lower abdomen,
descent or prolapse of pelvic organs,
difficulty emptying the bladder or bowels,
reduced quality of sexual life.

At the pathophysiological level there is:

stretching of muscle fibers,
damage to fascial structures,
disturbances of nerve conduction.

A particularly important aspect is that pelvic floor weakening may coexist with its excessive tension (so-called mixed dysfunction), which requires precise diagnostics and an individualized therapeutic approach.

Pelvic floor – risk factors

The condition of the pelvic floor is influenced by many factors, both biological and environmental. Their accumulation significantly increases the risk of dysfunction.

The most important risk factors include:

1. Pregnancy and childbirth

stretching of muscles and fascia,
nerve injuries,
vaginal deliveries, especially with the use of forceps or vacuum extraction.

2. Age and hormonal changes

a decline in estrogen levels leading to tissue weakening,
reduced muscle elasticity and regeneration.

3. Obesity

chronically elevated intra-abdominal pressure,
overloading of supportive structures.

4. Chronic increases in intra-abdominal pressure

chronic cough (e.g., in lung diseases),
constipation and excessive straining,
lifting heavy loads.

5. Lack of physical activity or improper training

weakening of the deep muscles,
incorrect movement patterns.

6. Pelvic surgeries

anatomical and nerve damage.

Understanding the risk factors is a key element of prevention and early intervention. Modern medicine emphasizes the importance of conscious body work, urogynecological physiotherapy, and individually tailored therapeutic methods.

Pelvic floor – treatment, therapy and modern supportive methods

The therapeutic approach to pelvic floor dysfunctions is multi-stage and requires individual adaptation to the type of disorder (weakness, overactivity, or mixed dysfunction), its severity, and the patient's general condition. The basis of treatment remains urogynecological physiotherapy, whose effectiveness has been confirmed in numerous clinical studies.

Key elements of therapy include:

pelvic floor muscle training (PFMT, pelvic floor muscle training) – aimed at improving muscle strength, endurance, and coordination,
biofeedback – enabling conscious control of muscle activity through feedback,
electrostimulation – used in cases of significant weakness or denervation,
manual therapy – involving work with soft tissues, fascia, and pelvic structures,
breath-posture re-education – restoring proper cooperation between the diaphragm, abdominal muscles, and the pelvic floor.

In postmenopausal women, topical estrogen therapy is also important, improving the trophic (nutrition and elasticity) of tissues.

Contemporary medicine also uses modern supportive methods that increase the effectiveness of conservative treatment and accelerate the regeneration of structures:

high-energy radiofrequency (e.g., INDIBA technology) – stimulates microcirculation, activates fibroblasts, and supports tissue regeneration,
gynecological laser therapy (e.g., fractional CO₂ or Er:YAG lasers) – improves tissue tone, increases collagen production, and affects mucosal revitalization,
new-generation medical electrical stimulation (EMG-triggered) – aids muscle activation in cases of significant dysfunction,
platelet-rich plasma therapy (PRP) – uses growth factors to regenerate tissues and improve their function,
magnetostimulation (HIFEM) – enables deep, noninvasive stimulation of the pelvic floor muscles.

In advanced cases, such as significant pelvic organ prolapse or severe forms of urinary incontinence, surgical treatment is considered, including reconstructive procedures and the implantation of suburethral slings.

The effectiveness of therapy depends on consistency, precise diagnostics, and integration of various treatment methods. In clinical practice, the best results are achieved by combining physiotherapy with modern supportive technologies.
