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.
By definition, postpartum pelvic floor dysfunction only affects women who have given birth, though pregnancy rather than birth or birth method is thought to be the cause. A study of 184 first-time mothers who delivered by Caesarean section and 100 who delivered vaginally found that there was no significant difference in the prevalence of symptoms 10 months following delivery, suggesting that pregnancy is the cause of incontinence for many women irrespective of their mode of delivery. The study also suggested that the changes which occur to the properties of collagen and other connective tissues during pregnancy may affect pelvic floor function.
Once patients with pelvic floor constipation have these basic tools, they can begin retraining the pelvic floor muscles with biofeedback. Based on the principle of operant conditioning, biofeedback provides auditory and visual feedback to help retrain the pelvic floor and relax the anal sphincter. Biofeedback training is the treatment of choice for medically refractory pelvic floor constipation, with some studies showing improvement in more than 70 percent of patients. Patients also learn to identify internal sensations associated with relaxation and long-term skills and exercises for use at home.
It can take several months of routine bowel or urinary medications and pelvic floor physical therapy before symptoms of pelvic floor dysfunction start to improve. The most important part of treatment is to not give up. Forgetting to take your medications every day will cause your symptoms to continue and possibly get worse. Also, skipping physical therapy appointments or not practicing exercises can slow healing.
Biofeedback is a modality that allows you to learn how to better control your muscles for optimal function. Biofeedback shows you what your muscles are doing in-real time. It is helpful to teach patients to lengthen and relax the pelvic floor for issues like general pelvic pain, painful sexual activity and constipation or to contract the pelvic floor in order to prevent leakage with activities like coughing, laughing, lifting, running or moving heavy objects. However, biofeedback does not demonstrate shortened muscles and tissues; therefore, in certain cases the biofeedback may seem to be within normal limits but yet the patient has 10/10 pain. In these incidences, manual palpation is more appropriate to identify restricted and shortened tissues and muscles, and myofascial trigger points.
Currently there is no surefire way to distinguish PFD from IC, and oftentimes patients have both conditions. Some healthcare providers examine pelvic floor muscles externally and internally to gauge their tightness (tightness indicates PFD). Other IC and PFD experts, like ICA Medical Advisory Board member, Robert Moldwin, MD, perform a lidocaine challenge. By instilling lidocaine into the bladder, Dr. Moldwin determines whether your pain is coming from your bladder, which would indicate IC.
If you think of the pelvis as being the home to organs like the bladder, uterus (or prostate in men) and rectum, the pelvic floor muscles are the home’s foundation. These muscles act as the support structure keeping everything in place within your body. Your pelvic floor muscles add support to several of your organs by wrapping around your pelvic bone. Some of these muscles add more stability by forming a sling around the rectum.
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.
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. Associations include obesity, menopause, pregnancy and childbirth. 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.
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.
You’ve likely already heard of kegels, the most common method for strengthening the pelvic floor. But there are plenty of additional exercises you can try to help train your pelvic floor. Watch this video to see yoga and fitness expert Kristin McGee (who recently gave birth to twins!) demonstrate three simple yet effective moves for strengthening your pelvic floor.
