测试并评价膝关节损伤后期膝屈伸肌峰力矩、屈膝肌峰力矩／伸膝肌峰力矩比值（Hamstring／quadriceps，H／Q），以便明确不同测试速度时的H／Q比值与膝关节损伤后期膝关节功能之间的关系。应用Cybex－330型等速肌力测试训练系统对41例单侧膝关节损伤后期病人的双侧膝屈伸肌进行等速肌力测试评定；采用Lysholm膝评定量表对患侧膝主观及临床功能情况进行评定。膝关节损伤后期膝屈伸肌峰力矩、单次最大做功量、平均功率及相应的W／Q比值在不同测试速度（60°s、180°s）时患膝与健膝之间差异不明显；患膝W／Q比值在低（＜50％）、最佳（50％～80％）、高（＞80％）时相应的膝评定量表得分之间的相差也不明显；然而，患膝与健膝比较，当H／Q比值相差（≤15％与＞15％）时的膝评定量表得分之间差异才有显著性（P＜0．01）。膝关节损伤后H／Q比值是一个不确定值，患膝与健膝H／Q比值之间的相差应在15％以内；膝关节损伤后康复训练应达到的最佳W／Q比值应该是对未受损伤的健侧膝的H／Q值。
Hamstring / quadriceps (H / Q) ratio of knee flexor and extensor muscle flexion and flexion, flexion and extension of knee flexion and extension at the late stage of knee joint injury were measured and evaluated in order to find out the relationship between H / Q ratio and knee late injury The relationship between knee function. Forty-one patients with bilateral knee flexors and extensors were evaluated with isokinetic strength test using Cybex-330 isokinetic test system. The Lysholm knee scale was used to evaluate the subjective and clinical features Assessment of the situation. Knee flexion and extension peak torque, single maximum work output, average power and corresponding W / Q ratio at the late stage of knee joint injury were not significantly different at different test speeds (60 ° s, 180 ° s) The knee-to-knee W / Q ratio was also not significantly different between the corresponding knee scale scores at low (<50%), best (50% to 80%), and high (> 80%); however, When compared with Knee Knee, there was no significant difference between Knee Rating Scale scores when the H / Q ratios were different (≤15% and> 15%) (P <0.01). The H / Q ratio after knee injury is an uncertain value, and the difference between the knee / knee H / Q ratios should be within 15%; the optimal W / Q ratio for rehabilitation training following knee injury should be H / Q values for uninjured contralateral knee.
