This paper deals with evaluation of the lower extremity efficiency and balance in rheumatoid arthritis (RA) patients. The authors' own test (LLFT-lower extremities functional test) and balance tests during normal standing and tandem positions with eyes opened or closed were used. Twelve patients with RA and fifteen controls for comparison were examined. Center feet of pressure dislocation on platform in normal standing with eyes open, normal standing with eyes closed, tandem left foot in front and tandem right foot in front positions and further dynamic balance tests on three different boards were analyzed. Visual Analogue Scale monitored the level of pain after each LLFT task. There was found a relation between the intensity of pain and overloading of joints in particular tasks, resulting in lower extremities dysfunction. A significant disbalance in medio-lateral direction during normal standing with eyes closed and tandem right foot in front positions and also in anterior-posterior direction in tandem right foot in front position during static balance tests was found. Correlations showed that patient's age, disease duration and Steinbrocker Functional Classes have an influence on parameters of balance tests. Results indicate that complex dysfunction of lower extremities causes disbalance of posture in static conditions.
本文探讨类风湿关节炎（RA）患者下肢功能效率及平衡能力的评估。采用作者自行设计的测试（LLFT-下肢功能测试）以及在睁眼或闭眼状态下正常站立和串联站立时的平衡测试。研究共纳入12例RA患者，并选取15名对照者进行比较。分析了睁眼正常站立、闭眼正常站立、左脚在前串联站立、右脚在前串联站立时平台上的中心压力偏移情况，以及在三种不同板上进行的进一步动态平衡测试。视觉模拟量表监测每次LLFT任务后的疼痛程度。研究发现特定任务中疼痛强度与关节负荷过重之间存在关联，进而导致下肢功能障碍。在静态平衡测试中，发现闭眼正常站立及右脚在前串联站立时在内外侧方向存在显著失衡，右脚在前串联站立时在前后方向也存在显著失衡。相关性分析表明，患者年龄、病程及Steinbrocker功能分级对平衡测试参数有影响。结果表明，下肢复杂功能障碍会导致静态条件下姿势失衡。
