Pelvic floor dysfunction is very different than pelvic organ prolapse. Pelvic organ prolapse happens when the muscles holding a woman’s pelvic organs (uterus, rectum and bladder) in place loosen and become too stretched out. Pelvic organ prolapse can cause the organs to protrude (stick out) of the vagina or rectum and may require women to push them back inside.
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.
What sets pelvic floor physical therapists apart is their in depth understanding of the muscles and surrounding structures of the pelvic floor, beyond what was taught in physical therapy graduate school. What that means for a patient who is seeking the help of a pelvic floor physical therapist, is that his or her pelvic floor issues will be examined and treated comprehensively with both internal and external treatment, provide them with lifestyle modifications to help remove any triggers, and receive specific exercises and treatment to help prevent the reoccurrence of pain once he or she has been successfully treated.
There are various procedures used to address prolapse. Cystoceles are treated with a surgical procedure known as a Burch colposuspension, with the goal of suspending the prolapsed urethra so that the urethrovesical junction and proximal urethra are replaced in the pelvic cavity. Uteroceles are treated with hysterectomy and uterosacral suspension. With enteroceles, the prolapsed small bowel is elevated into the pelvis cavity and the rectovaginal fascia is reapproximated. Rectoceles, in which the anterior wall of the rectum protrudes into the posterior wall of the vagina, require posterior colporrhaphy.

Pelvic floor dysfunction may include any of a group of clinical conditions that includes urinary incontinence, fecal incontinence, pelvic organ prolapse, sensory and emptying abnormalities of the lower urinary tract, defecatory dysfunction, sexual dysfunction and several chronic pain syndromes, including vulvodynia in women and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men. The three most common and definable conditions encountered clinically are urinary incontinence, anal incontinence and pelvic organ prolapse.
Nerves, organs, and joints can lose their natural mobility over time and cause a whole host of symptoms from pain, to loss of range of motion, and poor functioning of the bodily symptoms. Skilled and specialized therapists can use a variety of active techniques (patient assisted) and passive techniques to free up restrictions in these tissues and organs and improve overall function.
People with trigger points in their pelvic floor and surrounding areas can experience pain in the rectum, anus, coccyx, sacrum, abdomen, groin and back and can cause bladder, bowel, and sexual dysfunction. When physical therapists find a trigger point they work to eliminate it and lengthen it through a myriad of techniques. Recent literature has found that trigger point release alone can achieve an 83% reduction in symptoms.
Joint mobilization is a common and favorite tool of most orthopedic physical therapists. We love it so much because it can have so many different benefits depending on the type of technique used. Maitland describes types of joint mobilization on a scale between 1 and 5. Grade 1 and 2 mobilizations are applied to a joint to help to lessen pain and spasm. These types of mobilizations are typically used when a patient is in a lot of pain and to help break the pain cycle. On a non-painful joint, grade 3, 4, and 5 (grade 5 requires post graduate training) mobilizations can be used to help restore full range of motion. By restoring full range of motion within a restricted joint, it is possible to lessen the burden on that and surrounding joints, thereby alleviating pain and improving function.
It is essential that we, as pelvic floor physical therapists, also include other assessments when we are examining our patients for the very first time. We employ the tried and true physical therapy exam practices to determine if there is an underlying condition elsewhere in your body, such as a strength deficit or alignment issue that could be affecting your pelvic floor. It’s wild to think of it, but something as seemingly unrelated as a flat foot or a hip injury can be enough to set off pelvic and abdominal pain!
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.
Visceral mobilization restores movement to the viscera or organs. As elucidated earlier in our blog, the viscera can affect a host of things even including how well the abdominal muscles reunite following pregnancy or any abdominal surgery. Visceral mobilization aids in relieving constipation/IBS symptoms, bladder symptoms, digestive issues like reflux, as well as sexual pain. Visceral mobilization can facilitate blood supply to aid in their function, allow organs to do their job by ensuring they have the mobility to move in the way they are required to perform their function, and to allow them to reside in the correct place in their body cavity. Evidence is beginning to emerge to demonstrate how visceral mobilization can even aid in fertility problems.
During the internal exam, your physical therapist will place a gloved finger into your vagina or rectum to assess the tone, strength, and irritability of your pelvic floor muscles and tissues. Internal exams and internal treatment are invaluable tools that are taught to pelvic floor physical therapists. It can tell us if there are trigger points (painful spots, with a referral pattern or local); muscle/tissue shortening; nerve irritation and/or bony malalignment that could be causing your pain directly or inhibiting the full function of your pelvic floor muscles. We can also determine if your pelvic floor has good coordination during the exam. A pelvic floor without good coordination, may not open and close appropriately for activities such as going to the bathroom, supporting our pelvis and trunk, sexual activity, and keeping us continent.
