Sacroiliac Joint Rehab
The sacroiliac (SI) joint is where the sacrum (the triangle shaped bone at the base of your spine) meets the pelvis. There are 2 SI joints, one on each side. There are a lot of ligaments and surrounding muscles that reinforce the joints . One of the main functions of these joints is to transfer large forces between the trunk and the legs.
Sacroiliac Joint Pain can be caused by a traumatic injury (like a fall), repetitive activities, pregnancy, or may have an unknown cause.
Pain is typically on one side of the lower back and can radiate into the buttock and hip.
If you have had SI joint pain in the past, you may have heard that the joint is dysfunctional, fragile, unstable, or that it was "out of place." The truth is that the joint is none of these things and cannot very easily come out of place. There has been found to be very little movement at the SI joint. A research article by Sturreson et al. found that there is 2.5 degrees of rotation and .7 mm of translation at the SI joint. It has also been proven that clinicians cannot feel movement at the SI joint and they do not have the ability to change the position of the SI joint.
SI joint pain is best treated by strengthening the muscles around the joint that are weak and improving mobility in areas that are tight.
