Many physicians do not believe that the sacroiliac joint moves in any consequential way. As an Osteopathic physician, I believe that it does.
Here is a brief response to a viewer question who was referred to me for his sacroiliac or SI pain. His general practitioner told him that they do not move, and that his pain had to be from his hip, in spite of several negative radiological studies of his hip, and continuing pain even after ‘treatment’ for his hip pain.
The SI joint is at the intersection of the sacrum and the pelvic bone (see picture below), and while it does not move much- it does indeed move. With each step it rotates anteriorly with the push off of your leg, and posteriorly with extension of the opposite leg. Occasionally with stress or poor body mechanics, this joint can become ’stuck,’ sometimes causing significant pain from what are known as anterior or posterior inominate dysfunctions.

In a later post, I will provide you with some simple exercises you can do to help mobilize your SI joints, and I have asked Jorden Gold of the Stretch Zone to provide some stretches as well.
Later this week, look for my ergonomic review of the iPhone 4, and specifically how it compares functionally to the iPad.
Thanks for joining me!
