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.

With her finger inside me, Christensen mentioned that the three superficial pelvic floor muscles on each side were very tight and tensed when she touched them. I was too tight and in pain for her to check the deepest muscle (the obturator internus). Finally, she checked to see if I could do a Kegel or relax the muscles, and I was unable to do either.
