An expert on ankylosing spondylitis in Nanjing University of Politics Hospital said: Functional exercise is a painful and boring exercise. It is different from the casual health care of the elderly and the colorful slimming of women. In the early stage, functional exercise aimed at restoring joint function was carried out in a painful state. Especially in the stage of cooperative treatment, the inflammation of joints has not been completely controlled, or the nerve roots have not been relieved of oppression, and the exercise is completely carried out under pathological conditions. The exercise at this stage must be a movement that constantly challenges the limits and constantly breaks through the status quo. Only in this way can we resist the development of the disease and prevent the progressive contracture and calcification of ligaments. At the same time, extreme exercise can expose the potential illness, make the illness get timely and thorough treatment, and effectively prevent the second recurrence. It can be seen that treatment can prevent the development of inflammation, eliminate pain and accelerate the recovery of joint function. Functional exercise can improve blood circulation inside and outside joints, prevent muscle atrophy, joint fiber adhesion and dysfunction of metabolic process, enhance the muscle strength and flexibility of lumbar muscles, dorsal muscles and lower limb muscles, restore abnormal intervertebral joints and spinal stiffness to normal, and ensure the normal balance of spinal physiological structure and function. On the contrary, if we only rely on treatment without exercise, even if the inflammation and pain are eliminated, the pathological state of myofascial stiffness and contracture will not be completely improved. Under certain conditions (such as cold, fatigue, etc. ), it is difficult to avoid resurgence and recurrence. This is why the long-term curative effect of patients is very different under the same treatment conditions. It is worth mentioning that functional exercise should not be blind. Many patients with rigidity confuse endurance exercise with functional exercise. I thought that as long as I increased my exercise, I could avoid rigidity. This is not right. The exercise of ankylosing spondylitis focuses on moving the joints of the whole body. It is important to be gradual and persistent. Exercise slowly and gently, relax once and stretch extremely. Here, I recommend section 12 of Huang's bone-relaxing exercise compiled by the author according to years of clinical practice (attached at the end of the article). For example, Yijinjing 12, Tai Ji Chuan, Baduanjin and other traditional fitness exercises in China are not only exercises to strengthen muscles and bones, but also qigong functions of exhaling, relaxing muscles and activating collaterals, and regulating yin and yang, which can best reflect the spirit of internal and external unity and combination of static and dynamic. As for simple endurance training, such as long-distance running, it has no significance to joint function except to exercise people's endurance. What's more, rigidity is a physical disease, and excessive physical labor should be avoided. Especially long-term illness can lead to physical weakness. Many patients are weak because of long-term suffering from illness. If you blindly carry out high-intensity endurance training, it will only lead to more and more weakness. In addition, it is important to keep the correct posture every day! When standing, try to hold your chest high and raise your head. When sitting, try to stretch your back. It is not advisable to sit on a low stool. You must sleep in a flat bed for life, use a low pillow, sleep on your back or prone as much as possible, and straighten your knees when sleeping. Don't sleep with your knees curled up. For most patients with ankylosing spondylitis, the functional exercise that accompanies them for a lifetime is like sailing against the current. If you don't advance, you will retreat. Giving up not only means giving up all previous efforts, but also means endless future troubles. Therefore, we must fully realize the seriousness of rigidity and have the determination and will to exercise for life. It should be noted that paying is rewarding, and health is the last word!
