Fatigue Level Assessment
Fatigue is one of five patient-reported domains feeding the BASDAI score.
- 0–10: Scale range (visual analogue scale)
- 7 days: Recall window (past-week average)
- 1 of 5: Domain weight (BASDAI questions)
- Patient: Reported by (self-assessment)
Why fatigue matters
Fatigue often precedes flares and tracks with systemic inflammation.
Placeholder: fatigue score is entered directly on the BASDAI questionnaire.
Spinal and Hip Pain Rating
Axial pain is the hallmark symptom of ankylosing spondylitis.
- 0–10: Scale range (visual analogue scale)
- SI joints: Common sites (spine, hips)
- 1 of 5: Domain weight (BASDAI questions)
- Inflammatory: Pattern (worse with rest)
Axial pain pattern
Pain typically improves with movement and worsens after inactivity.
Placeholder: spinal/hip pain anchors the axial component of the score.
Peripheral Joint Pain and Swelling
Peripheral arthritis can accompany axial disease in some patients.
- 0–10: Scale range (visual analogue scale)
- Knees, ankles: Common joints (asymmetric pattern)
- 1 of 5: Domain weight (BASDAI questions)
- ~30%: Prevalence (placeholder figure)
Peripheral involvement
Swelling and tenderness outside the spine are scored separately.
Placeholder: peripheral joint symptoms add a distinct BASDAI input.
Morning Stiffness Duration and Severity
Stiffness duration and intensity form two related BASDAI questions.
- 0–120 min: Duration range (slider input)
- 0–10: Severity scale (visual analogue scale)
- 2 of 5: Domain weight (duration + severity)
- >30 min: Typical flare (placeholder threshold)
Stiffness scoring
Longer, more severe morning stiffness raises the composite score.
Placeholder: stiffness duration and severity are averaged together.
BASDAI Score and Activity Threshold
A score of 4 or higher generally indicates active disease.
- 0–10: Score range (composite index)
- ≥ 4: Active threshold (clinical cutoff)
- Score-based: Biologic candidacy (plus NSAID failure)
- Periodic: Reassessment (placeholder interval)
Interpreting the score
The gauge marks where the current inputs fall against the threshold.
Placeholder: scores at or above 4 suggest escalation of therapy.
