脊柱のバイオメカニクスに関する理論的背景

抄録

It is difficult to understand the biomechanics of the control and stability of the spine and pelvis. The factors for this are that the orientation of the muscle fibers in the abdominal muscles are diverse and the abdominal muscles are composed of layers. Therapeutic approaches for impairment of the abdomen need the theory of the biomechanics of the spine and pelvis. This paper proposes several theories of the biomechanics of the spine and pelvis. These theories are called: soil function, double ladder structure, air bag function and sacroiliac joint stability. These functions are expained in this paper.
