Pollard LC et al. – The findings suggest that low pain thresholds reflect “fibromyalgic” rheumatoid arthritis (RA) (many tender points) and central pain sensitization with prolonged disease duration.
- A cross–sectional observational study (105 patients with RA) assessed pain thresholds using an algometer.
- Regression analysis examined the influence of demographic and clinical assessments.
- Pain thresholds (median 289, interquartile range 89–434) correlated with assessments of disease activity (tender joint counts), disability (Health Assessment Questionnaire), fatigue, depression, and anxiety.
- Ordinal logistic regression showed tender point counts and disease duration were the dominant contributors.
