BASDAI and Ankylosing Spondylitis

Its name stands for Bath Ankylosing Spondylitis Disease Activity Index. It records your recent experience of fatigue, spinal and joint pain, areas of tenderness, and morning stiffness. The score supports a clinical review; it does not confirm the diagnosis or show structural damage by itself.

Each question uses a rating scale, and the answers are combined into an overall disease-activity score. A higher result reflects a heavier symptom burden at that time. The direction of change is often more informative than one isolated result, particularly when the questionnaire is completed consistently.

BASDAI captures the patient's experience, so it complements rather than replaces an examination, blood tests, imaging, and discussion of daily function. Poor sleep, another illness, a recent activity change, or pain from a different condition can influence answers.

Answer for the time period printed on the form and use the scale exactly as shown. Consider all relevant symptoms rather than only the worst moment. Complete it before an appointment if requested, and bring earlier results so your clinician can compare patterns.

Keep a brief note of medication changes, exercise, sleep disruption, and unusual physical demands. This context can explain a change and helps the care team decide whether physiotherapy, exercise planning, medication review, or further assessment fits your needs.

Arrange a clinical review if pain, stiffness, fatigue, or reduced movement is worsening, disrupting sleep, or limiting work and usual activities. Contact your care team if symptoms change substantially despite following the agreed plan; do not change prescribed medicine solely because of a questionnaire result.

Seek urgent assessment for new weakness or numbness in both legs, loss of bladder or bowel control, numbness around the groin, severe breathing difficulty, a painful red eye with light sensitivity, or major spinal pain after an injury.

Ask what has changed compared with your previous score, whether another problem could be affecting it, and which treatment goal matters most now. You can also ask how often to repeat BASDAI and what other findings will guide the next decision.
