摘　　要：目的评估球海绵体肌反射(BCR)联合肛门外括约肌肌电图(EAS-EMG)在骶神经损害的诊断应用价值。方法选取2020年1月至2021年12月温州医科大学衢州市人民医院门诊住院诊断为骶神经损害的患者48例作为观察组,同时收集同时段在门诊检查的健康志愿者48名作为对照组,分别记录BCR、EAS-EMG的电生理数值。并分析其单项及联合检测的AUC曲线面积、敏感度和特异度。结果观察组与对照组比较,BCR检测阳性率、BCR潜伏期、EAS-EMG阳性率存在显著差异(P<0.05)。ROC曲线面积分析,EAS-EMG的诊断敏感度、特异度为72.9%、89.6%,BCR检测诊断的敏感度、特异度为75.0%、97.9%。EAS-EMG联合BCR诊断敏感度、特异度为85.4%、91.7%。结论BCR检测用于诊断骶神经损害比较敏感,BCR联合EAS-EMG检测可提高诊断骶神经损害阳性检出率。Objective To evaluate the diagnostic value of Bulbocavernous Reflex(BCR)combined with External anal sphincter electromyography(EAS-EMG)n the diagnosis of sacral nerve damage.Methods A total of 48 patients diagnosed with sacral nerve injury in Quzhou People's Hospital of Wenzhou Medical University from January 2020 to December 2021 were selected as the study group,and 48 healthy volunteers examined in the outpatient department at the same time were collected as the control group,and the electrophysiological values of BCR and EAS-EMG were recorded respectively.The AUC curve area,sensitivity and specificity of single and combined detection were analyzed.Results Compared with the control group,there were significant differences in BCR positive rate,BCR latency and EAS-EMG positive rate(P<0.05).Based on ROC curve area analysis,the diagnostic sensitivity and specificity of EAS-EMG were 72.9%and 89.6%,while that of BCR were 75%and 97.9%.The sensitivity and specificity of EASEMG combined with BCR were 85.4%and 91.7%.Conclusion BCR detection is sensitive in the diagnosis of sacral nerve injury,and BCR combined with EAS-EMG can improve the positive detection rate of sacral nerve injury.
