The sacroiliac joint, although having minimal movement, can be a source of lower back pain.
We need to understand a little of its anatomy to appreciate its significance as a pain producing joint.
The SI joint allows for five movements:
A perfect example of the strength of a sacroiliac joint can be seen in football players. Although subjected to excessive forces, severe injuries to the SI joint in this sport is relatively uncommon.
Throughout your body, where stability is needed motion is minimized.
Provided there exists proper alignment, a full range of motion, proper muscle and ligament strength and function the SI joints should remain fully functional and pain-free.
However, with pelvic imbalance, inadequate strength and improper motion the SI joint will be subjected to injurious stresses and will become pain expressive.
Trauma due to falls and accidents may also result in painful SI joints.
The health of the SI joint is maintained and promoted, like all joints, through proper alignment and regular motion as is achieved by exercising through a full range of motion. This is best achieved by daily, full stride, brisk walking.
However, if misalignment is present even walking can be a painful experience and add to inflammation and subsequent harmful and permanent degeneration.
When range of motion is compromised stress processes will cause a degenerative response that produces inflammation, joint fixation, muscular and ligament weaknesses or imbalances and joint degradation which results in pain.
Women during pregnancy are more prone to SI joint stress and more likely to experience SI joint problems. This is due to the added body weight, the anterior abdominal weight causing a forward pelvic tilt and hormonal changes that naturally occur to facilitate delivery during the birthing process.
Much of this added stress can be minimized with attention to correcting any spinal-pelvic misalignment, strengthening and toning muscles, maintaining proper posture, wearing the right kind of shoes and engaging in regular brisk walking throughout the pregnancy.
