Authors and colleagues have continued research on flexibility of spinal vertebrae. For evaluation of spinal movement, an idea of three circles or spherical surfaces would be presented for head, chest and pelvis. Connection points are i) mastoid process of the head motion sphere, ii) the sternoclavicular joint of the chest motion sphere, and iii) the upper posterior iliac spine of the iliac bone. When each sphere rotates forward or backward, another sphere rotates in the opposite direction. They have mutual connecting relationships, which bring us delicate and minute movements. This article will be expected to be some reference.
