Low back pain often results from various forms of sacroiliac dysfunction.
Of the ten or so ways the sacrum can become stuck “crooked” between the two innominate bones; the most common is labeled a unilateral flexed sacrum, normally secondary to prolonged standing with weight bearing on one leg .
Right motor dominant people often present with one sided Psoas (core muscle) tightness, which causes the right hip to drop forward and back and the pelvic bowl to left rotate and side shift over the left leg. In an attempt to balance the crooked pelvis, the brain often recruits the left QL (back muscle) to flatten the lordosis misalignment .
