Human Rational Posture from Evolution and Anatomical Structure
Reasonable standing posture can not only reduce the burden and pressure on people's spine,prevent spinal diseases such as scoli-osis and disc herniation,but also maintain the shape of the human body,which is of great significance to the health of the human spine.At present,there are many theories about human standing posture,which are also elaborated from different angles,but there are still many argu-ments about reasonable standing posture in the academic circle,because of the different judgment basis.Some people think that the proper posture is the pelvis in a medium position,with a slight lumbar lordosis,a slight thoracic kyphosis,and the head in a balanced position.It has also been suggested that the proper stance is a line of the head that begins in the external auditory canal(or at the mastoid of the temporal bone),passes vertically across the acromion,lumbar vertebra,shoulder headland,slightly backward in front of the hip axis,knee axis,and ends slightly in front of the lateral ankle or lateral ankle,overlapping with the baseline connecting the center of the center of the center of the center of the supporting area.But there is no basis for these judgments.Therefore,this paper will look for the basis of reasonable posture from the evolutionary law and anatomical structure of the human body,so as to form a new criterion,and then summarize several parameters of rea-sonable posture to provide a basis for reasonable posture of the human body.
