Ah, the pelvis!  

The pelvis consists of a "bony bowl" made up by two halves (ilia) that come together in the front at the symphysis pubis and in the back into the sacrum through joint called the sacroiliac joints (SI joints).








These joints can be painful when there is poor balance in the pelvis and/or one is stiff and the other is loose. People often call this SI pain or low back pain. 

The inside of the pelvic bowl is lined with muscles. These include the pelvic floor muscles and hip rotation muscles.  Inside this muscle bowl lie the pelvic organs. Much of what we often refer to as "internal" manual therapy or internal work is directed to treat these muscles. It can be done through the vagina or rectum:  transvaginal or transrectal, with one or two gloved fingers. We can also work on the tailbone from the inside of the pelvis. This is needed in so many people. Many people have tailbone injuries from childhood. Many people have decreased movement or total loss of movement of the tailbone (coccyx). We also work on the other structures of the pelvis.

I, Jeannette Zyderveld, PT, first learned the mainstream pelvic physical therapy and earned the CAPP (Certificate of Achievement in Pelvic Physical Therapy) through seminars, exams and an article written about a case study (of one of my patients)  with the APTA (American Physical Therapy Association). This type of therapy involves thorough examination, extensive knowledge of the scientific studies in this area, and what evidence there is confirming the benefits of this therapy. Education of treatment included training in use of biofeedback, strengthening home exercise programs, vaginal weights, devices women can use for mechanical feedback about their pelvic floor muscle contractions, electrical stimulation, education for the patients, and much more. Manual therapy is taught also, but as with general physical therapy nothing like what John Barnes teaches. As with any other part of your body: it is connected with everything else in your body and results are limited when treated in isolation.   I practiced the mainstream pelvic PT for a couple years and took a seminar in visceral mobilization. My eyes were opened to the importance of fascia! I started to take both John Barnes seminars and Barral Visceral Manipulation seminars. Each time I thought: "this is the best work!". about either one. But after the second out of 4 visceral manipulation seminars, I realized that John Barnes' work is vastly superior. This was based on how I was able to practice each approach with my patients and the results my patients were reporting. One session of John Barnes approach yielded far more. I did learn a great amount of anatomy and (energetic) palpation of the viscera in the thorax, abdomen and pelvis. I feel it adds greatly to doing my John Barnes MFR.  And when I feel something very specific in the organs, I still sometimes switch to using some Barral techniques. I feel so lucky to have these best of both (actually three) worlds to offer you! I am passionate about it becuase of the results I experience myself and the results I have with clients.
