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.
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.
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.
Ultrasound uses high-frequency sound waves applied through a wand or probe on your skin to produce an internal image or to help treat pain. Real-time ultrasound can let you see your pelvic floor muscles functioning and help you learn to relax them. Therapeutic ultrasound uses sound waves to produce deep warmth that may help reduce spasm and increase blood flow or, on a nonthermal setting, may promote healing and reduce inflammation.
For internal massage, your PT may insert a finger into the vagina or rectum and massage the muscles and connective tissue directly. A frequently used technique is “Thiele stripping,” in which your therapist finds a trigger point by feeling a twitch in the muscle underneath, exercising it using a circular motion, and then putting pressure on it to help relax it, repeating the process until the muscle starts to release. Internal massage can also help release nerves. Sometimes, anesthetics can be injected into these trigger points. PTs may do this in a few states, but in most states, a doctor or nurse must administer injections.

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.
Patients may meet individually with a dedicated nurse educator who provides a focused session on bowel management techniques. Central to the process is a daily regimen that combines an evening dose of fiber supplement with a morning routine of mild physical activity; a hot, preferably caffeinated beverage; and, possibly, a fiber cereal followed by another cup of a hot beverage — all within 45 minutes of waking. This routine augments early morning high-amplitude peristaltic contractions by incorporating multiple colon stimulators.
Pelvic floor physical therapists specialize in the muscles, nerves and connective tissues that live between your legs, also known as the pelvic floor. They gain their expertise through a series of post-graduate continuing education classes, certifications, and training. Their training allows them to perform both internal and external pelvic exams, and broadens their knowledge of conditions which affect the pelvic floor. Sometimes, people who specialize in modalities like biofeedback or dilator therapy, advertise themselves as pelvic floor therapists, but don’t have any hands on experience treating the sensitive and often reactive muscles of the pelvic floor. If you are seeking pelvic floor physical therapy, it is important to enquire about the experience and level of training your potential physical therapist has had in this specialty.
