【摘要】 目的:评价RA患者与对照组在同运动状态下的膝屈伸肌的肌肉功能和协调活动差异,为RA患者制定康复方案提供依据。方法:病人来自2005-2007年,按1987美国风湿病协会诊断标准,我院门诊或病房收治的早期(<2年)RA患者24例,按年龄、性别选择正常人24例,进行配对研究。让测试者做最大等长收缩和主动收缩运动,同时用ME6000型表面肌电仪对实验组和对照组进行等长肌肉收缩功能和主动运动进行表面肌电信号测试。结果:RA患者在主动运动中,试验组股二头肌(BF)的SEMG振幅均值比对照组的SEMG振幅均值低(p<0.05),股外侧肌(VL)的SEMG振幅均值比对照组的SEMG振幅均值高(p<0.05),实验组的协同收缩率比对照组高(p<0.05)。结论:类风湿关节炎患者在做收缩运动时,拮抗肌没有完全放松,说明实验组肌肉运动有明显的不协调;可以用表面积电信号来评价RA患者肌肉的功能与平衡。更多还原

【Abstract】 Objective To evaluate muscular function and the coactivity of the knee flexors and extensors in patients with RA and healthy gourp in order to provide rehabilitation program for RA. Methods Patients come from our hospital and outpatient,2005-2007,coincidence with the diagnosis standard of ARA in 1987,24 earlier RA of patients(〈2 old years〉, To choose normal 24 people,carrying on paired-sample study.Muscle function and coactivity were tested in experimenter during maximal isotonic contraction and initiative constriction motion. surface electromyography(sEMG) were analyzed and collected by ME6000 during maximal isotonic contraction and initiative constriction motion. Results The mean amplitude of the electromyograms of the biceps femoris in RA were significantly lower during initiative contraction and vastus lateralis were bigger than those of the non-diseased knees. The antagonistic coactivity ratios in RA were higher than in the non-diseased during initiative contraction .and hamstring coactivity ratios were also higher(p<0.05). Conclusions Demonstrated antagonism muscle in patients with RA were not slackened and not coordination during initiative constriction motion. SEMG can be used to quantitatively evaluate muscle function in patients with RA.更多还原
