Pelvic floor dysfunction is an umbrella term for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. Although this condition predominantly affects females, up to 16% of males suffer as well.[1] Symptoms include pelvic pain, pressure, pain during sex, incontinence, incomplete emptying of feces, and visible organ protrusion.[2] Tissues surrounding the pelvic organs may have increased or decreased sensitivity or irritation resulting in pelvic pain. Underlying causes of pelvic pain are often difficult to determine.[3] The condition affects up to 50% of women who have given birth.[4]
Pelvic floor physical therapists specialize in the muscles, nerves and connective tissues that live between your legs, also known as the pelvic floor. They gain their expertise through a series of post-graduate continuing education classes, certifications, and training. Their training allows them to perform both internal and external pelvic exams, and broadens their knowledge of conditions which affect the pelvic floor. Sometimes, people who specialize in modalities like biofeedback or dilator therapy, advertise themselves as pelvic floor therapists, but don’t have any hands on experience treating the sensitive and often reactive muscles of the pelvic floor. If you are seeking pelvic floor physical therapy, it is important to enquire about the experience and level of training your potential physical therapist has had in this specialty.
Obstructed Defecation: Obstructed defecation is difficulty getting bowel movements out of the body. Although the stool reaches the rectum, or bottom of the colon, the patient has difficulty emptying. This often makes patients feel that they need to go the bathroom more often, or that they cannot empty completely, as if stool remains in their rectum. Obstructed defecation may be caused by pelvic floor prolapse (discussed below), pain symptoms or muscles not functioning normally.
Although many centers are familiar with retraining techniques to improve pelvic floor dysfunction, few have the multidisciplinary expertise to teach patients with constipation how to appropriately coordinate abdominal and pelvic floor muscles during defecation, and how to use bowel management techniques, along with behavior modification, to relieve symptoms. Because pelvic floor dysfunction can be associated with psychological, sexual or physical abuse and other life stressors, psychological counseling is often included in the evaluation process.
Pelvic floor dysfunction is a group of disorders that change the way people have bowel movements and sometimes cause pelvic pain. These disorders can be embarrassing to discuss, may be hard to diagnosis and often have a negative effect on quality of life. Symptoms vary by the type of disorder. Many general practitioners may not be familiar with pelvic floor dysfunction, and it may take a specialist, such as a colorectal surgeon, to discover the correct diagnosis.
To assess the degree of dysfunction, three measurements must be taken into account. First, an anatomic landmark known as the pubococcygeal line must be determined, which is a straight line connecting the inferior margin of the pubic symphysis at the midline with the junction of the first and second coccygeal elements on a sagittal image. After this, the location of the puborectalis muscle sling is assessed, and a perpendicular line between the pubococcygeal line and muscle sling is drawn. This provides a measurement of pelvic floor descent, with descent greater than 2 cm being considered mild, and 6 cm being considered severe. Lastly, a line from the pubic symphysis to the puborectalis muscle sling is drawn, which is a measurement of the pelvic floor hiatus. Measurements of greater than 6 cm are considered mild, and greater than 10 cm severe. The degree of organ prolapse is assessed relative to the hiatus. The grading of organ prolapse relative to the hiatus is more strict, with any descent being considered abnormal, and greater than 4 cm being considered severe.[2]
When mechanical, anatomic, and disease- and diet-related causes of constipation have been ruled out, clinical suspicion should be raised to the possibility that PFD is causing or contributing to constipation. A focused history and digital examination are key components in diagnosing PFD. The diagnosis can be confirmed by anorectal manometry with balloon expulsion and, in some cases, traditional proctography or dynamic magnetic resonance imaging defecography to visualize pathologic pelvic floor motion, sphincter anatomy and greater detail of surrounding structures.
