The pelvic floor is a combination of multiple muscles with ligamentous attachments creating a dome-shaped diaphragm across the boney pelvic outlet. This complex of muscles spans from the pubis (anterior) to the sacrum/coccyx (posterior) and bilateral to the ischial tuberosities. The bulk of the pelvic musculature is the levator ani, composed of the puborectalis, pubococcygeus, and iliococcygeus. The puborectalis wraps as a sling around the anorectal junction accentuating the anorectal angle during contraction and is a primary contributor to fecal continence. Elevation and support of the pelvic organs are associated with the pubococcygeus and the iliococcygeus. The pubococcygeus is the most medial component which separates, fashioning the levator hiatus with openings for the urethra, vagina (females), and anus. The bulbospongiosus and ischiocavernosus muscles are the primary contributors to the superficial portion of the anterior pelvic floor. The more superficial musculature of the posterior pelvic floor constitutes the external anal sphincter. The transverse perineal muscles cross the mid-portion of the superficial aspect of the pelvic floor and coalesce with the bulbospongiosus muscles and external anal sphincter as the perineal body.

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.

Surface electrodes (self-adhesive pads placed on your skin) can test your pelvic muscle control. This might be an option if you don’t want an internal exam. The electrodes are placed on the perineum (the area between the vagina and rectum in women, and between the testicles and rectum in men) or on the sacrum (the triangular bone at the base of your spine). This test is not painful.
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]
Kegels: American gynecologist Arnold Kegel created this seminal pelvic floor exercise. To do a Kegel, contract your muscles that stop the flow of urine, hold for five seconds, then release for five seconds. Repeat this exercise 10–15 times, up to three times per day. Avoid doing Kegel exercises when urinating since stopping the flow midstream can cause some urine to remain in your bladder, putting you at a higher risk of urinary tract infections (UTIs).
