摘要： 目的探讨改制Biodex 等速肘关节配件(mEA)的效度和信度。方法由评定员A对25 名健康自愿者分别使用标准的Biodex 等速肘关节配件(sEA)、mEA进行右侧肘屈伸的等速肌力测试；3 d 后由评定员B使用mEA再次进行右侧肘屈伸的等速肌力测试；将使用不同配件的测试结果作相关性检验来验证mEA 的效度；对不同测试者使用mEA 的评测结果来分析评定者间信度。结果使用mEA的测试结果与sEA在各主要等速指标上均呈高度相关(P<0.05)。在各等速指标上组间相关系数(ICC)均大于0.75(P<0.05)。结论mEA具有良好的效度和信度。

Abstract: To study validity and reliability of the modified elbow attachment (mEA) of Biodex. Methods 25 healthy volunteers participated in the study. The tester A used mEA and standard elbow attachment (sEA) separately to test right elbow flexor and extensor of these volunteers within a day. The tester B used mEA to assess the same muscles of the same volunteers 3 days later. The correlation between mEA and sEA were analyzed to test the validity and reliability of mEA. Results mEA was highly correlated with sEA in all isokinetic test data (P<0.05). The interclass correlation coefficients (ICC) were more than 0.75 in most isokinetic test data (P<0.05). Conclusion The mEA has a good validity and reliability.
