The spine is the second lifeline of the human body, which occupies a central position in the human body and affects human health. The survey results of some primary schools in Beijing show that 68% of children have spinal abnormalities, and the incidence of scoliosis in different degrees is as high as 20%. In adults, 80% of headaches, backaches, lumbago and numbness of hands and feet actually stem from spinal abnormalities in adolescence.

Based on the assumption that the health of the body depends partly on the normal function of the nervous system, it emphasizes that the body is a self-regulating and self-repairing organism. The functions of the body are controlled and coordinated by the brain, spinal cord and nerves all over the body. The movable spine protects the conduction pathway of the nervous system, especially the fragile spinal nerve root and the spinal nerve running between the two vertebral bodies. The loss of normal movement and position of the spine will damage the function of nerves and lead to abnormal functions of tissues and organs. Chiropractors call this change of spinal function and its potential influence on the nervous system spinal subluxation syndrome. The method of spine correction is to find out the abnormal spine, relieve its influence on nerves and restore the body to a healthy state.
