SI/Sacroiliac Joint Dysfunction

The sacroiliac/SI joint is found in the pelvis and it links the spine to the pelvis. It is commonly believed that when this joint loses mobility it will cause local pain. This is a favourite chiropractic diagnosis. I have found in my practice that this is seldomly the root of back pain. If the joint truly loses it's motion, I find it is secondary to loss of support somewhere in the pelvis; one of the four corners is not being held in place.

Therefore reintroducing motion back into this joint whether it is with an "adjustment/manipulation" or some mobilization technique will only be short lived. Once the person starts stressing the pelvic muscle that is not up to speed, the SI joint will once again get "stuck" or lose its motion. This is why the treatment needs to be redone so frequently.

I have never found a "stuck" sacroiliac joint that did not have one of the pelvic muscles not supporting it's respective end.
In other words, if all corners of the pelvis are properly supported, then the need for continual SI joint treatment usually subsides. Once this has been attained then good form walking should keep the SI joint functional.
