Bath Ankylosing Spondylitis Disease Activity Index

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a questionnaire used by healthcare providers to assess how active and severe ankylosing spondylitis (a type of inflammatory arthritis affecting the spine) is in a patient. It asks about symptoms like fatigue, back pain, joint stiffness, and morning stiffness over recent days. Patients rate their symptoms on a numerical scale, helping doctors determine how well current treatments are working and whether adjustments are needed. The BASDAI provides a standardized way to monitor disease activity and guide treatment decisions effectively.
