Abstract

Objective. To examine the correlation between disease activity of RA and the risk of falling.Methods. Seventy-eight patients were tested. Disease activity was measured with acute-phase reactants, autoantibodies, swollen and tender joint count (SJC28, TJC28), pain on a visual analogue scale (VAS pain), patient and evaluator global assessment of disease activity (PGA, EGA), HAQ disability index (HAQ-DI), 28-joint DAS (DAS-28) and the clinical and simple disease activity indexes (CDAI, SDAI). The risk of falling was evaluated by a fall assessment consisting of Tinetti test (TIT), timed get up and go test (TUG), chair-rising test (CRT), tandem walk and tandem stand test.Results. During the last 12 months, 26.9% of the participants reported a fall and 46.2% mentioned the fear of falling. The most evident link [Spearman's correlation (r(s))] with the results of the fall assessment was found in HAQ-DI (CRT: r(s) = 0.523, TUG: r(s) = 0.620, TIT: r(s) = -0.676), CDAI (CRT: r(s) = 0.460, TUG: r(s) = 0.504, TIT: r(s) = -0.472), VAS pain (CRT: r(s) = 0.441, TUG: r(s) = 0.616, TIT: r(s) = -0.548) PGA (CRT: r(s) = 0.473, TUG: r(s) = 0.577, TIT: r(s) = -0.520) and TJC (CRT: r(s) = 0.488, TUG: r(s) = 0.394, TIT: r(s) = -0.385). Patients with higher disease activity achieved poorer results in the fall assessment.Conclusion. The strongest correlation with falls was evident for patient-reported outcomes. Pain seems to be the common ground of these parameters. At the same time, disease activity influences pain. The results suggest an increased attention towards the risk of falling with patients of higher levels of disease activity or pain, and physio- or ergotherapeutical interventions as needed.
