In order for the processes of urination and defecation to go smoothly, the various muscles within the pelvis need to act in a coordinated manner. In some cases, the muscles contract when they should be relaxing, or the muscles do not relax sufficiently to facilitate coordinated movement. Problems with the pelvic floor muscles can lead to urinary difficulties and bowel dysfunction. PFD is experienced by both men and women.
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.
Treatment is based on the cause of the dysfunction and severity of symptoms. Surgical treatment is rarely needed for pelvic floor dysfunction, except for large, symptomatic rectoceles or other pelvic prolapse. In the case of prolapse, surgery may help to restore the normal location of pelvic organs. This may be performed through the abdomen or through the bottom, depending on the specific problem.

Home exercise programs are essential for each patient. In the case of weakness, a patient will require more pelvic floor, core and functional strengthening and stability exercises. For overactive and pain conditions, the HEP typically consists of relaxation techniques, self-massages (both external and internal), gentle stretching, cardiovascular fitness as tolerated, and eventually pain-free core stability exercises. Both require postural and behavioral modifications and self-care strategies.

Issues with the pelvic floor can arise from a multitude of reasons. Infections, previous surgeries, childbirth, postural and lifting problems, and trips and falls can all bring on pelvic floor dysfunction. Pelvic floor pain can persist well after the cause of it has been removed. So it is entirely possible to feel the effects of an old infection, surgery or injury, days to years after they occur. Anyone who has had long standing abdomino-pelvic pain, or pain that they can’t seem to get rid of after seeking the help of medical doctors or other healthcare providers is a good candidate for a pelvic floor physical therapy evaluation and possible curative treatment.
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.
Once we determine the cause of our patient’s pelvic floor dysfunction, we design a plan tailored to the patient’s needs. At Beyond Basics, we have a diverse crew of physical therapists who bring their own training and background into each treatment. What is really beautiful about that, is that all teach and help each other grow as practitioners. It will be difficult to go over every single type of treatment in one blog post, but we will review some of the main staples of pelvic floor rehab.
Pelvic floor dysfunction can be diagnosed by history and physical exam, though it is more accurately graded by imaging. Historically, fluoroscopy with defecography and cystography were used, though modern imaging allows the usage of MRI to complement and sometimes replace fluoroscopic assessment of the disorder, allowing for less radiation exposure and increased patient comfort, though an enema is required the evening before the procedure. Instead of contrast, ultrasound gel is used during the procedure with MRI. Both methods assess the pelvic floor at rest and maximum strain using coronal and sagittal views. When grading individual organ prolapse, the rectum, bladder and uterus are individually assessed, with prolapse of the rectum referred to as a rectocele, bladder prolapse through the anterior vaginal wall a cystocele, and small bowel an enterocele.[10]

Mechanistically, the causes of pelvic floor dysfunction are two-fold: widening of the pelvic floor hiatus and descent of pelvic floor below the pubococcygeal line, with specific organ prolapse graded relative to the hiatus.[2] Associations include obesity, menopause, pregnancy and childbirth.[5] Some women may be more likely to developing pelvic floor dysfunction because of an inherited deficiency in their collagen type. Some women may have congenitally weak connective tissue and fascia and are therefore at risk of stress urinary incontinence and pelvic organ prolapse.[6]

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]
Myofascial release is a more gentle technique that can be useful in cases where a patient is already experiencing a great deal of pain. The therapist will hold gentle pressure at the barrier of the tissue (the point where resistance is felt) for a short period of time, usually less than 2 minutes until the therapist feels the tissue release on its own. The therapist does not force the barrier.
As physical therapists, are our hands are amazing gifts and phenomenal diagnostic tools that we can use to assess restrictions, tender points, swelling, muscle guarding, atrophy, nerve irritation and skeletal malalignment. We also use our hands to treat out these problems, provide feedback to the muscles, and facilitate the activation of certain muscle groups. There have been a great number of manual techniques that have evolved over the course of physical therapy’s history. Let’s go over a few.
