About this calculator
The BASDAI (Ankylosing Spondylitis Disease Activity Index) calculator measures inflammatory activity in ankylosing spondylitis. It uses six questions assessing symptoms like pain, fatigue, and physical limitations. Each item is scored from 0 to 10, with the average indicating disease activity.
BASDAI scores range from 0 to 10. Scores above 4 suggest significant inflammation, while below 2 indicate good control. It's a quick tool for patients and healthcare providers to track flare-ups or treatment responses.
Use this calculator to monitor disease flare-ups or evaluate the effectiveness of anti-inflammatories and biologics. It doesn't replace lab tests or rheumatologist visits but provides a subjective health overview.
Note: BASDAI is a self-assessment. Atypical symptoms like excessive fatigue without inflammation may not be captured. Always consult a physician for diagnoses and treatment adjustments.
