Patients with rheumatoid arthritis have a number of clinical scales to assess the activity of the disease and to determine whether the rheumatoid arthritis is under control. In layman’s terms, when a patient with rheumatoid arthritis has no joint swelling and pain, and there is no significant morning stiffness of the joints, and the laboratory blood sedimentation and C-reactive protein are normal, the patient in this condition is called to have achieved clinical remission. If you have a double-handed X-ray every 1-2 years and find that there is no progression of bone destruction, it is called rheumatoid arthritis in control, which is also called clinical remission in clinical practice. Some patients do not reach this standard, they may have mild joint pain, and the blood sedimentation and C-reactive protein are slightly, which is called rheumatoid arthritis patients in a state of low disease activity, which also belongs to a clinical standard.
