To explore the application value of needle electromyography (EMG) and nerve conduction study (NCS) in the forensic appraisal; to provide scientific basis for establishing normative and unified assessment methods of the peripheral nerve study in forensic medicine.
One hundred and sixty-four samples with injured peripheral nerve (injury group) and 138 samples with normal peripheral nerve (control group) were collected and tested with methods of EMG and NCS respectively. The relevance rate of two methods were compared and statistical analysis was performed.
In the injury group, there was no statistical difference on the relevance rate between the application of EMG and that of NCS (P > 0.05). In the control group, there was no statistical difference on the negative rate between the two methods (P > 0.05). The false negative rate of the injury group and the false positive rate of the control group were both 0% when using the two methods together.
When the injured peripheral nerve in forensic appraisal is in doubt, application of both EMG and NCS could disclose truth from falsehood. The accuracy and credibility of identification results could be enhanced.
探讨针极肌电图（EMG）和神经传导速度测定（NCS）在法医学鉴定中的应用价值；为建立规范统一的法医学周围神经检查评估方法提供科学依据。
收集164例周围神经损伤样本（损伤组）和138例周围神经正常样本（对照组），分别采用EMG和NCS方法进行检测。比较两种方法的符合率并进行统计学分析。
损伤组中，EMG与NCS应用的符合率差异无统计学意义（P＞0.05）。对照组中，两种方法的阴性率差异无统计学意义（P＞0.05）。两种方法联合应用时，损伤组的假阴性率和对照组的假阳性率均为0%。
在法医学鉴定中，当周围神经损伤情况存疑时，联合应用EMG和NCS可明辨真伪，提高鉴定结果的准确性和可信度。
