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.
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.
