The BASDAI or Bath Ankylosing Spondylitis Disease Activity Index is a validated diagnostic test which allows a physician, usually a rheumatologist, to determine the effectiveness of a current drug therapy, or the need to institute a new drug therapy for the treatment of Ankylosing spondylitis (AS). The BASDAI is one of a group of classification criteria for spondyloarthropathies. ==Bath Index measures== The BASDAI consists of a 1 - 10 scale measuring discomfort, pain, and fatigue (1 being no problem and 10 being the worst problem) in response to six questions asked of the patient pertaining to the five major symptoms of AS: #Fatigue #Spinal pain #Arthralgia (joint pain) or swelling #Enthesitis, or inflammation of tendons and ligaments (areas of localized tenderness where connective tissues insert into bone) #Morning stiffness duration #Morning stiffness severity To give each symptom equal weighting, the average of the two scores relating to morning stiffness is taken. The resulting 0 to 50 score is divided by 5 to give a final 0 – 10 BASDAI score. Scores of 4 or greater suggest suboptimal control of disease, and those patients are usually good candidates for a change in their medical therapy, may benefit by treatment with biologic therapies, or may be candidates for enrollment in clinical trials evaluating new drug therapies directed at treating the AS disease process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BASDAI」の詳細全文を読む スポンサード リンク
