The first purpose of the SIJ is to provide stability, which is promoted partly by the muscles attached to the SIJ and is provided by multiple mechanisms, embracing the complex of ligaments fixed to the SIJ. The range of motion of SIJ is estimated around 2 to 4 degrees. Additionally, 35 muscles attach to the sacrum or innominate, which act in a combined effort with the fascial and ligaments, thus ensuring movement and simultaneously stability of the trunk and lower extremities. The SIJ also is an essential generator for pe... view more»
