Ankylosing spondylitis, psoriatic arthritis and other spondyloarthropathies are a class of chronic disabling diseases, and the goal of rehabilitation treatment emphasizes the maximum protection and restoration of spondyloarthropathies, so that the loss of function and disability caused by the disease is reduced to a minimum. 1.Standing posture training: try to stand and walk with your head up, eyes level, chest up and abdomen in order to maintain a good body posture. When reading a book, newspaper, or writing, keep the line of sight parallel to the book or newspaper to avoid the cervical vertebrae from leaning forward or backward for too long. If necessary, you can train your back to stand against the wall, and “four points against the wall training” (heel, hip, shoulder, pillow four points against the wall), twice a day, 10-30 minutes each time. 2, sitting training: use a straight-backed hard chair, the upper body straight abdomen, as far as possible backward against the back of the chair, hip, knee flexion 90 °, avoid sitting on a low bench or sofa, so as not to bend over time. 3, lying training: sleep on a hard bed, low pillow or no pillow, avoid using high pillow, maintain the physiological curvature of the neck and waist spine. In the morning and bedtime every morning and evening to take a prone position, time 10-20min, not too long, so as not to affect breathing. If the physiological curvature of the spine has disappeared or is already ankylosed, a pillow can be placed on the back in the horizontal position to prevent or delay the formation of kyphosis. In addition, it should be noted that patients should not adopt the same position and posture for a long time regardless of their choice, but should change their position appropriately and alternate with walking and physical activities to maintain the normal physiological curvature of the spine and prevent the formation of deformity from being accelerated or aggravated by poor posture and position. In the joint function training, attention should also be paid to maintaining the thoracic mobility, so as to avoid the backbend of the spine extrusion thorax affect the respiratory function. The methods to maintain thoracic mobility include deep breathing exercises, abdominal breathing exercises, and chest expansion exercises. Specific methods are: supine position, hands naturally placed on both sides, bending the knees, for deep breathing exercises. Can also stand or sitting position, can also do chest expansion exercises.
