BASDAI Calculator Calculate the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to assess disease activity in ankylosing spondylitis. — free online calculator.
Formula
- BASDAI Calculator calculates its result from Fatigue/tiredness (0-10), AS neck/back/hip pain (0-10), Non-neck/back joint pain/swelling (0-10), Discomfort from tender areas (0-10), Morning stiffness level (0-10), Morning stiffness duration (0-10, where 10=2+ hrs). It uses the formula BASDAI = (Q1 + Q2 + Q3 + Q4 + (Q5+Q6)/2) ÷ 5. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Fatigue/tiredness, AS neck/back/hip pain, Non-neck/back joint pain/swelling, Discomfort from tender areas, Morning stiffness level, Morning stiffness duration (0-10, where 10=2+ hrs). Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: BASDAI
- Fatigue/tiredness: 5 0-10
- AS neck/back/hip pain: 5 0-10
- Non-neck/back joint pain/swelling: 5 0-10
- Discomfort from tender areas: 5 0-10
- Morning stiffness level: 5 0-10
- Morning stiffness duration (0-10, where 10=2+ hrs): 5
Using Fatigue/tiredness (0-10) = 5, AS neck/back/hip pain (0-10) = 5, Non-neck/back joint pain/swelling (0-10) = 5, Discomfort from tender areas (0-10) = 5, Morning stiffness level (0-10) = 5, Morning stiffness duration (0-10, where 10=2+ hrs) = 5, the calculated result is 5.
