We studied peroneal motor conduction in 186 normal patients (206 nerves) and in 36 patients with 38 peroneal nerve lesions localized to the knee by electromyography. The efficiency of the test, or percentage of times the test results were true, was used to find the optimal point to separate the normal patients from patients with peroneal nerve lesions at the knee. This analysis revealed that the best indicator for localizing a peroneal nerve lesion to the knee was a greater than 20% drop in peroneal motor amplitude across the knee. This gave a calculated efficiency of 99.52% and detected 60% to 70% of peroneal nerve lesions at the knee.
我们研究了186例正常患者（206条神经）以及36例经肌电图检查发现腓总神经在膝关节处有病变的患者的腓总神经运动传导情况。通过测试的有效性，即测试结果为真的次数所占百分比，来找出区分正常患者与膝关节处腓总神经病变患者的最佳分界点。该分析表明，将腓总神经病变定位到膝关节的最佳指标是膝关节处腓总神经运动幅度下降超过20%。由此计算出的有效性为99.52%，且能检测出60%至70%的膝关节处腓总神经病变。
