The sacroiliac joints are two of the most important support centers of the body, positioned where the body’s weight transfers from the spine obliquely through the pelvis to the legs. Studies conclude that the sacroiliac joints are important sensors of large force streams between the trunk and legs in which the largest muscles of the body are involved. In this respect, the sacroiliac joint functions as a multi-directional force transducer.

The base of the spinal column, the sacrum, is supported at its attachment to the iliac bones of the pelvis solely by strong ligaments that make up the sacroiliac joints. Within these ligaments are nerves which control and orient the body’s posture. Sprain of these ligaments caused instability (looseness) which leads to muscle spasm, pain, and postural imbalances throughout the body.
