Objective 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. Methods 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. Results 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. Conclusion 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.%目的 探讨针极肌电图与神经传导检测在法医学鉴定中的应用价值,为建立规范、统一的周围神经检测评价方法提供科学依据.方法 选取周围神经损伤者164例(损伤组)和正常者138例(对照组),分别应用针极肌电图及神经传导检测两种方法进行检测,对两种方法的检出率进行比较及统计分析.结果 损伤组中,应用针极肌电图与神经传导检测的检出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).同时应用两种方法在损伤组中的假阴性率和正常组中的假阳性率均为0％.结论 在法医学鉴定中对疑有周围神经损伤者,同时应用针极肌电图与神经传导检测有助于提高鉴定结论的准确性.
