We examined function of the sacroiliac joints clinically before and after stretching of the pelvic floor muscles in 25 patients suffering from the sacrococcygeal (pelvic floor) syndrome. Our findings were that:
- the pelvic floor muscles are predominantly shortened on the right side in this syndrome
- this shortening changes the position of the sacral bone
- the shortening causes bilateral blockade of the sacroiliac joints in the craniocaudal direction and an asymetrical blockade in the ventrodorsal direction.
