Physical therapists (PTs) are experts in movement and function, which sounds like a pretty broad topic to be an expert in, and it is. After physical therapists graduate PT school (now-a-days at the doctoral level), they find their niche and specialize. You can find PTs working with high-level athletes, children, infants, people who are recovering from injuries, people with neurological conditions and many other types of clients.
One of the great benefits to skin rolling is it increases the circulation in the area to which it was applied. Often times, areas that are tight or restricted are receiving reduced blood flow and oxygen. By bringing blood flow to the area, toxins can be cleared and the healing contents of the blood are brought to the injured area. Skin rolling can also restore the mobility of surrounding joints and nerves, which can help to restore normal function. By allowing the skin to move more freely, pelvic congestion, heaviness and aching can be effectively treated.
There is not a surgery to treat pelvic floor dysfunction because it is a problem with your muscles. In rare circumstances, when physical therapy and biofeedback fail to work, your provider might recommend you see a pain injection specialist. These doctors specialize in localizing the specific muscles that are too tense or causing pain, and they can use a small needle to inject the muscle with numbing medication and relaxing medication. This is called trigger point injection.
Pelvic floor dysfunction is an umbrella term for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. Although this condition predominantly affects females, up to 16% of males suffer as well.[1] Symptoms include pelvic pain, pressure, pain during sex, incontinence, incomplete emptying of feces, and visible organ protrusion.[2] Tissues surrounding the pelvic organs may have increased or decreased sensitivity or irritation resulting in pelvic pain. Underlying causes of pelvic pain are often difficult to determine.[3] The condition affects up to 50% of women who have given birth.[4]
As many as 50 percent of people with chronic constipation have pelvic floor dysfunction (PFD) — impaired relaxation and coordination of pelvic floor and abdominal muscles during evacuation. Straining, hard or thin stools, and a feeling of incomplete elimination are common signs and symptoms. But because slow transit constipation and functional constipation can overlap with PFD, some patients may also present with other signs and symptoms, such as a long time between bowel movements and abdominal pain.

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.[2] Associations include obesity, menopause, pregnancy and childbirth.[5] 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.[6]
The American Society of Colon and Rectal Surgeons is dedicated to ensuring high-quality patient care by advancing the science, prevention and management of disorders and diseases of the colon, rectum and anus. These brochures are inclusive but not prescriptive. Their purpose is to provide information on diseases and processes, rather than dictate a specific form of treatment. They are intended for the use of all practitioners, health care workers and patients who desire information about the management of the conditions addressed. It should be recognized that these brochures should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtain the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all the circumstances
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.
Myofascial release is a more gentle technique that can be useful in cases where a patient is already experiencing a great deal of pain. The therapist will hold gentle pressure at the barrier of the tissue (the point where resistance is felt) for a short period of time, usually less than 2 minutes until the therapist feels the tissue release on its own. The therapist does not force the barrier.

Obstructed Defecation: Obstructed defecation is difficulty getting bowel movements out of the body. Although the stool reaches the rectum, or bottom of the colon, the patient has difficulty emptying. This often makes patients feel that they need to go the bathroom more often, or that they cannot empty completely, as if stool remains in their rectum. Obstructed defecation may be caused by pelvic floor prolapse (discussed below), pain symptoms or muscles not functioning normally. 

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.[2]

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.

Kegels: American gynecologist Arnold Kegel created this seminal pelvic floor exercise. To do a Kegel, contract your muscles that stop the flow of urine, hold for five seconds, then release for five seconds. Repeat this exercise 10–15 times, up to three times per day. Avoid doing Kegel exercises when urinating since stopping the flow midstream can cause some urine to remain in your bladder, putting you at a higher risk of urinary tract infections (UTIs).
