Rheumatoid arthritis (RA) is a chronic, inflammatory and multiple-system disorder of connective tissue. It frequently affects joints and periarticular structures of feet that constitute a significant supporting element underlying normal gait and motion of the body centre of gravity. The aim of the study was to evaluate foot deformities on the basis of plantography examination in RA patients according to the severity of the disease.
The study was performed on 54 RA patients. The control group consisted of 34 volunteers free of any disorders. Plantography examination was carried out by means of a CQ ST2K podoscope. The following parameters were applied to the assessment of the disturbances of foot statics: hallux valgus angle (α), Sztriter-Godunow index (KY), Wejsflog's index (Wwp) and Clarke's angle (CL).
Markedly higher values of the α angle were noted in RA patients, reflecting the presence of hallux valgus. Moreover, values of the α angle were higher in patients in the third stage of radiological changes than those in the second one. On the other hand, values of Clarke's angle for the right foot were significantly higher in men in the second and third stage of RA compared to the control group. The most common deformities in RA patients include HV and transverse flat foot, more explicit in women in the third stage of RA.
Plantography examination has been shown to constitute a useful diagnostic tool for assessment and monitoring of foot deformities in RA patients.
类风湿性关节炎（RA）是一种慢性、炎症性的结缔组织多系统疾病。它经常影响足部关节和关节周围结构，而这些结构是身体重心正常步态和运动的重要支撑要素。本研究的目的是根据疾病严重程度，通过足底压力图检查评估类风湿性关节炎患者的足部畸形情况。
对54例类风湿性关节炎患者进行了研究。对照组由34名无任何疾病的志愿者组成。通过CQ ST2K足诊仪进行足底压力图检查。以下参数用于评估足部静态紊乱情况：拇外翻角（α）、斯特里特 - 戈杜诺夫指数（KY）、韦伊斯弗洛格指数（Wwp）和克拉克角（CL）。
类风湿性关节炎患者的α角值明显更高，反映出拇外翻的存在。此外，放射学改变处于第三阶段的患者的α角值高于第二阶段的患者。另一方面，与对照组相比，类风湿性关节炎第二和第三阶段男性患者右脚的克拉克角值明显更高。类风湿性关节炎患者最常见的畸形包括拇外翻和横弓扁平足，在类风湿性关节炎第三阶段的女性中更为明显。
足底压力图检查已被证明是评估和监测类风湿性关节炎患者足部畸形的一种有用诊断工具。
