During an evaluation of a patient it might be found that the iliopsoas muscle is chronically shortened. Hip extension would be limited because of the tightened short iliopsoas. To achieve a normal range of hip extension, there would necessarily be increased pelvic tilt and motion and lumbar lordosis. The increased pelvic motion would take L4 and L5 with it creating a probable unstable hypermobile lower two lumbar segments. The T12/L1 area would according to Janda become the next normal fixed area necessary for the increased function of the lower lumbars and pelvis. Adjustment of T12/L1 before stretching the shortened psoas could result in loss of normal stabilization for the lower lumbars and pelvis and possible increased lower spinal hypermobility.
When evaluating the locomotor system it is becoming more and more clear to me that we must look at all of the dysfunction wherever it is located to especially solve the chronic spinal pain. Chiropractors who only treat the spinal subluxation without paying attention to the whole structure may find themselves adjusting the same segments over and over again because the underlying cause of the subluxation is extravertebral.
