About the BASDAI
The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a short questionnaire about the past week, widely used worldwide to track ankylosing spondylitis and axial spondyloarthritis. It is scored from 0 to 10. A score of 4 or more is commonly used to indicate active disease, but your rheumatologist interprets it together with your examination, blood tests (CRP) and, often, the ASDAS score.

This is a self-help tool, not a diagnosis. It helps you keep track and talk to your doctor. If you feel very unwell, have a high fever, chest pain, sudden weakness or vision loss, seek medical care straight away.
