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.
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.
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.
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.
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.
