The muscles of the pelvic floor must work together and in coordination to perform specific tasks. The pelvic floor has to contract, elongate and relax in very precise ways to perform basic functions like urination, defecation, support the pelvis and organs, and sexual function and pleasure. If your pelvic floor muscles and/or nerves fail to do what they are supposed to do at the right time, problems like painful sex, erectile dysfunction, constipation, and incontinence can occur.
Neural mobilization as the name implies, involves the restoration of neural structures back to their normal mobility: to glide and slide. Neural structures that cannot move properly can cause pain that can radiate down an extremity or into the trunk and can give the sensation of burning, zinging, and stabbing. Some orthopedic therapists practice this type of mobilization; common examples include the sciatic nerve in the leg and the ulnar nerve in the arm. Pelvic floor PTs focus on these nerves when they cause issues, but they also pay attention to nerves that innervate the perineum and genital region (bicycle seat area), such as the pudendal, iliohypogastric, obturator, ilioinguinal, genitofemoral and the femoral cutaneous nerves. By allowing these nerves to move freely, symptoms such as vulvovaginal, penile, rectal, clitoral and testicular pain, itching and burning can be greatly improved.
Pelvic floor dysfunction can be diagnosed by history and physical exam, though it is more accurately graded by imaging. Historically, fluoroscopy with defecography and cystography were used, though modern imaging allows the usage of MRI to complement and sometimes replace fluoroscopic assessment of the disorder, allowing for less radiation exposure and increased patient comfort, though an enema is required the evening before the procedure. Instead of contrast, ultrasound gel is used during the procedure with MRI. Both methods assess the pelvic floor at rest and maximum strain using coronal and sagittal views. When grading individual organ prolapse, the rectum, bladder and uterus are individually assessed, with prolapse of the rectum referred to as a rectocele, bladder prolapse through the anterior vaginal wall a cystocele, and small bowel an enterocele.
Home exercise programs are essential for each patient. In the case of weakness, a patient will require more pelvic floor, core and functional strengthening and stability exercises. For overactive and pain conditions, the HEP typically consists of relaxation techniques, self-massages (both external and internal), gentle stretching, cardiovascular fitness as tolerated, and eventually pain-free core stability exercises. Both require postural and behavioral modifications and self-care strategies.

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.
