The “pelvic floor” refers to a group of muscles that attach to the front, back, and sides of the pelvic bone and sacrum (the large fused bone at the bottom of your spine, just above the tailbone). Like a sling or hammock, these muscles support the organs in the pelvis, including the bladder, uterus or prostate, and rectum. They also wrap around your urethra, rectum, and vagina (in women).
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.
Medications: Daily medications that help to keep your bowel movements soft and regular are a very important part of treating pelvic floor dysfunction. Some of these medications are available over-the-counter at the drugstore and include stool softeners such as MiraLAX®, Colace®, Senna or generic stool softeners. Your primary care doctor or a gastroenterologist can help to advise you which medications are most helpful in keeping your stools soft.
Biofeedback uses electrodes placed on your body (on the perineum and/or the area around the anus) or probes inserted in the vagina or rectum to sense the degree of tenseness in your pelvic floor muscles. Results displayed on a computer or other device provide cues to help you learn to relax those muscles. Usually, patients feel relief after six to eight weeks of therapy. You may be able to buy or rent a unit to use at home.
Squats: Squats are a great holistic exercise because they engage many muscles at once. To do a body-weight squat, stand with your feet shoulder-width apart, then slowly bend your knees, dropping your hips and glutes down and back, keeping your back straight, as if you’re sitting down on a chair. (You can place your hands on your hips or stretch them out in front of you for balance.) Bend your knees until your thighs are parallel with the floor, then return to an upright position. Repeat 10 times, up to three times per day.
