In clinical practice, patients with ankylosing spondylitis are often found to be in a state of chronic inactivity or hypermobility in order to reduce or avoid pain in the affected joints, resulting in muscle atrophy or joint contracture, which can lead to disability of a joint or limb that was not severe and could have recovered. The correct approach is to receive anti-inflammatory medication to keep joint pain under control and to move the joint in a timely, careful and gradual manner. During the acute phase, gentle passive movement of the joint, to the extent that joint pain first appears, once or twice a day, can help reduce joint contracture. When not exercising, the acutely inflamed joint should be placed in an appropriate position (functional position) or braked with a deck so that some more joint function can be maintained in the future in the event of an unavoidable contracture or deformity that cannot be corrected. During the subacute and acute phases, stretching exercises of the spine and extremities should be maintained, which will both increase the range of motion of the joint or maintain it and relieve pain caused by muscle spasm or tension. The number, duration, and frequency of daily activities should be gradually increased according to the degree of pain tolerance. Again, it is important to emphasize that adherence to exercise in all areas of the ankylosing spondylitis patient is as important as medication.
