Bath AS Disease Activity Index (BASDAI)

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a tool used by doctors to measure how active and severe symptoms are in people with ankylosing spondylitis, a type of inflammatory arthritis affecting the spine. It involves asking patients to rate things like fatigue, back pain, joint pain, swelling, stiffness after waking, and how tired they feel during the day. These ratings help doctors assess disease activity, monitor changes over time, and decide on the best treatment approach to improve quality of life.
