健康年轻人腕关节等速肌力测试的测试者内信度和间信度

背景:越来越多研究运用等速肌力测试评估腕关节肌力,但未见有腕关节等速肌力测试的测试者内和测试者间信度报道。目的:观察健康受试者等速肌力测试腕关节屈伸肌力的峰力矩和总功的重测信度。方法:28例健康受试者随机等分为2组。第1次测试2组分别由测试者A、B在60(°)/s和180(°)/s角速度下测试。第2次测试,2组均由测试者B完成测试。结果与结论:在60(°)/s和180(°)/s下,腕关节屈肌和伸肌的峰力矩和总功的测试者内重测信度为0.65-0.95,测试者间重测信度为0.70-0.95。在低速和高速下健康受试者腕关节等速肌力测试的峰力矩和总功的重测信度为好到极好。

Intra-and interrater reliability in the isokinetic muscle strength test of wrist joint in healthy youth

BACKGROUND：Increased studies use the isokinetic dynamometry to evaluate the wrist strength.But no intra-and interrater reliability of isokinetic muscle strength test in wrist joint has been reported.OBJECTIVE：To observe the peak torque and total work generated by the wrist flexion and extension muscles in healthy youth during isokinetic muscle strength test.METHODS：Twenty-eight healthy subjects were randomly divided into two groups.Each subject in the two groups was tested twice at 60（°）/s and 180（°）/s angular velocities.In the first session,subjects in group A were tested by rater A and subjects in group B were tested by rater B.In the second session,all subjects were tested by rater B.RESULTS AND CONCLUSION：The intrarater reliability intraclass correlation coefficients of peak torque and total work values for wrist flexion and extension ranged from 0.65 to 0.95 at 60（°）/s and 180（°）/s angular velocities.The interrater reliability intraclass correlation coefficients ranged from 0.70 to 0.95.The peak torque and total work of isokinetic muscle strength test for wrist joint displayed good to excellent intra-and interrater reliability at low and high angular velocities in healthy youth.
