Theoretical and experimental investigation of the balance effects using the relation of head position and airway width from RAMPA based orthopedics

From the mechanical point of view, human body is one of the deformable structures which are forced by gravity and the constriction forces of muscles. As a result of deformation, forward-positioned head, curved spine, narrow airway, narrow palatal bone and narrow tongue space, etc. are caused. The cause of the deformation might be efficient survival of life. The cause- and -effect relationship among airway, head posture and height is presented in this study.
