1、法医学杂志2014年6月第30卷第3期·18l·正常人不同姿势膝关节等速肌力测试黄婷婷,夏晴,范利华,高东,张敏(1.司法部司法鉴定科学技术研究所上海市法医学重点实验室,上海200063;2.复旦大学附属中山医院,上海200032;3.南通大学附属医院,江苏南通226001)摘要:目的研究应用CON—TREXBiomechanicalTestandTraining系统测试膝关节肌力时。分析不同姿势对测试结果的影响,从而选择最适用于法医学鉴定的肌力检测条件方法对52例正常人分别在未固定姿势和固定姿势两种条件下进行60~/s和30。/s速度的等速肌力测试,对这两种
2、条件下双侧膝关节屈、伸肌的峰力矩(peaktorque,PI’)、峰力矩角度(peaktorqueangle,PrrA)进行统计学分析。结果在未固定姿势,两种测试速度下受试者膝关节屈、仲肌的Prr双侧比较差异均存在统计学意义(P<0.05);在固定姿势,两种测试速度下受试者膝关节屈、伸肌的PrI1双侧比较差异均无统计学意义(P>0.05)。不论受试者身体姿势是否加以固定,其膝关节屈、伸过程的PTA双侧比较差异均无统计学意义(P>0.05)。结论受试者姿势的规范对测试结果,对有影响,因此,在进行膝关节等速肌力测试时应规范受试者的姿势。关键词:法医学;膝关节;等速
