If an internal examination is too uncomfortable for you, your doctor or physical therapist may use externally placed electrodes, placed on the perineum (area between the vagina and rectum in women/testicles and rectum in men) and/or sacrum (a triangular bone at the base of your spine) to measure whether you are able to effectively contract and relax your pelvic floor muscles.
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.
The therapist may do manual therapy or massage both externally and internally to stabilize your pelvis before using other kinds of treatment. Manual therapy takes time and patience, and may require one to three sessions per week, depending on the technique used and your response to treatment. You may feel worse initially. However, many patients see improvement after six to eight weeks.
