Abstract

Rheumatoid arthritis is a chronic inflammatory joint disease which affects the joints and soft-tissues of the foot and ankle. The aim of this study was to evaluate biomechanical foot function and determine factors associated with localised disease burden in patients with this disease. Seventy-four rheumatoid arthritis patients (mean (standard deviation) age, 56 years (12); median (interquartile range) disease duration, 13 (5, 19)) and 54 able-bodied adults (mean (standard deviation) age, 55 years (12)) completed the Leeds foot impact scale. Biomechanical foot function was measured using three-dimensional instrumented gait analysis. Disease activity score, the number of swollen and tender foot joints, and rearfoot and forefoot deformity were recorded. Sequential multiple linear regression was undertaken to identify independent predictors of foot disease burden.
