简介：类风湿性关节炎的足部和踝关节经历高度破坏性的滑膜炎，肌肉力量丧失。目的：为评价类风湿性关节炎患者踝关节等速肌力，材料与方法：选取30例类风湿性关节炎踝关节受累患者和30例年龄、性别、种族、体重指数、下肢优势度相匹配的健康人（对照组）。在等速Cybex Norm测力计上评估所有受试者的背屈、跖屈、内翻和外翻。类风湿性关节炎和对照组之间的变量进行了比较，右踝和左踝之间，背屈肌/跖屈肌和内翻肌/外翻肌的力量比determined.Results：类风湿性关节炎患者进行统计学差的等速测力测试的所有踝关节运动。两组背屈肌群与跖屈肌群的肌力比值不同。内翻肌和外翻肌比率无显著差异。在这两个组的跖屈肌肌肉组织是统计学上强于dorsiflexors.Conclusion：我们得出结论，类风湿性关节炎患者的等速肌力测试表现较差，所有踝关节运动比对照组，与类似的等速测试结果被观察到的右侧和左侧在两组中，只有少数例外。等速评估对类风湿性关节炎患者没有额外的风险，如严重的疼痛或炎症活动。(C)2014 Elsevier Editora Ltda.

Introduction:The foot and ankle in rheumatoid arthritis undergo highly destructive synovitis with loss of muscle strength. Objective: To evaluate the muscle strength of ankles in patients with rheumatoid arthritis based on isokinetic dynamometry parameters.Materials and methods: Thirty patients with a diagnosis of rheumatoid arthritis involving the ankle(s) and 30 healthy subjects (control group) matched for age, gender, race, body mass index and lower limb dominance were studied. Dorsiflexion, plantar flexion, inversion and eversion were evaluated in all subjects on an isokinetic Cybex Norm dynamometer. The variables were compared between the rheumatoid arthritis and control groups and between the right and left ankles, and the dorsiflexor/plantar flexor and invertor/evertor muscle strength ratio was determined.Results: Patients with rheumatoid arthritis performed statistically worse in the isokinetic dynamometry test for all ankle movements. The muscle strength ratio between dorsiflexors and plantar flexors was different in the two groups. No significant differences were observed in the invertor and evertor ratios. In the two groups the plantar flexor musculature was statistically stronger than dorsiflexors.Conclusion: We conclude that patients with rheumatoid arthritis perform worse in isokinetic dynamometry regarding all ankle movements than control subjects, with similar isokinetic test results being observed for the right and left side in both groups, with few exceptions. Isokinetic evaluation posed no additional risk such as important pain or inflammatory activity to patients with rheumatoid arthritis. (C) 2014 Elsevier Editora Ltda. All rights reserved.
