Ankylosing spondylitis belongs to the category of “paralysis” in Chinese medicine, which is characterized by pain in the lumbar spine, swelling and pain in the joints, restriction in the movement of both hips, and even stiffness of the lumbar spine and deformation of the spine. Traditionally, it is believed that this disease is due to deficiency of endowment, deficiency of liver and kidney, wind, cold, dampness, heat and other evil spirits taking advantage of the deficiency, involving the kidney meridian, the bladder meridian and the Governor’s Vessel, thus classifying this disease as “kidney paralysis”, “bone paralysis”, “tortoise back” and “Governor’s Vessel disease”. The disease is classified as “kidney paralysis,” “bone paralysis,” “tortoise back,” and “disease of the Governor’s Vessel. After many years of clinical practice, we are the first in the Chinese medicine field to propose that this disease belongs to the category of “tendon paralysis” in Chinese medicine. In terms of treatment, we believe that the disease has different pathological states during the active and remission periods, and we treat the disease in stages according to the principle of “treating the symptoms when it is urgent, and treating the root cause when it is slow”. In response to the pathological characteristics of spasm and ankylosis, he proposed the academic theory of “spasm relief and relaxation” as the main treatment for ankylosing spondylitis, which has been repeatedly clinically proven to form a more complete treatment system.
