Vasculitis & polymyalgia rheumatica
Test-retest reliability of pain visual analogue scale (VAS)/numerical rating score (NRS), stiffness VAS/NRS, Health Assessment Questionnaire-Disability Index (HAQ-DI) and modified Health Assessment Questionnaire (mHAQ) in polymyalgia rheumatica: An OMERACT study
Authors' conclusion
Pain severity VAS/NRS, stiffness severity VAS/NRS, HAQ-DI and mHAQ all demonstrate good to excellent test-retest reliability in a PMR patient population.
Study context
- Population
- Participants with polymyalgia rheumatica (PMR) and stable disease
- Outcome
- Test-retest reliability (ICC) of pain VAS/NRS, stiffness VAS/NRS, HAQ-DI and mHAQ; ICC 0.8-0.9 good, >0.9 excellent
- Follow-up
- Testing interval of two to six weeks
Methodological detailstest-retest reliability, two prospectively collected datasets, ICC, two-way mixed effects model, absolute agreement, Only participants with stable disease included in analyses
- Test-retest reliability
- Two prospectively collected datasets
