摘要: 目的 研究应用CON-TREX Biomechanical Test and Training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,对这两种条件下双侧膝关节屈、伸肌的峰力矩(peak torque,PT)、峰力矩角度(peak torque angle,PTA)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、伸肌的PT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PT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PT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。

Abstract: Objective To study the influence of different positions in the isokinetic muscle test of knees by CON-TREX Biomechanical Test and Training System, so as to select the suitable conditions for forensic identification of muscle strength test. Methods Fifty-two healthy volunteers joined the isokinetic muscle strength test in unfixed and fixed position, respectively and in two kinds of angular speed (60°/s and 30°/s). The differences of peak torque (PT) and peak torque angle (PTA) between bilateral knee flexor and extensor were statistically analyzed. Results In the unfixed position, under the two speed, there was statistically significant difference in PT between bilateral knee flexor and extensor(P<0.05); while in the fixed position, under the two speed, there was no statistically significant difference (P>0.05). In any kind of conditions, the PTA of bilateral knee flexor and extensor did not have statistically significant difference(P>0.05). Conclusion The position of the subject influences the results of PT. So the position of subject in knees isokinetic muscle test should be regulated.
