人体脊椎具有支持躯干、保护内脏器官的作用。随着年龄的增长,脊椎会出现退变、偏位,使生理曲度发生改变,人体椎骨在20岁左右停止发育,30岁左右开始退变。
The human spine has the function of supporting the trunk and protecting the internal organs. With age, the spine will degenerate and deviate to change the physiological curvature. The vertebra of the human body will stop developing around the age of 20 and begin to degenerate after the age of 30.
