Shortening of the Pelvic Floor Muscles Influences the Position of the Sacral Bone and Causes Asymetrical Movement of the Sacroiliac Joints

Summary

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: 1) the pelvic floor muscles are predominantly shortened on the right side in this syndrome, 2) this shortening changes the position of the sacral bone, and 3) the shortening causes bilateral blockade of the sacroiliac joints in the craniocaudal direction and an asymetrical blockade in the ventrodorsal direction.
