肌电图课件-H反射与F波的区别

·糖尿病与并发症·糖尿病新世界2022年11月糖尿病新世界DIABETES NEW WORLD神经肌电图测定Fmean、Fchd 及Hmin 对糖尿病周围神经病变的诊断价值龚建捷，蔡吓明，林华雪莆田学院附属医院功能检查科肌电图室，福建莆田351100[摘要]目的分析神经肌电图测定H 波最短潜伏期（Hmin ）、F 波平均潜伏期（Fmean ）、F 波离散度（Fchd ）对糖尿病周围神经病变（diabetic peripheral neuropathy,DPN ）的诊断价值。

方法回顾性选取2020年2月—2022年6月莆田学院附属医院收治的38例DPN 患者作为DPN 组，另选取同期医院收治的38例单纯糖尿病（diabetes mellitus ，DM ）患者作为DM 组。

入院时，患者均接受神经肌电图检查，并记录相关参数（Fmean 、Fchd 及Hmin ）；比较两组患者上述参数，绘制受试者工作特征（receiver operating characteristic ，ROC ）曲线分析Fmean 、Fchd 及Hmin 诊断DPN 的价值。

结果DPN 组患者Fmean 、Fchd 及Hmin 值均大于DN 组，差异有统计学意义（P <0.05）。

绘制ROC 曲线图，结果显示，Fmean 、Fchd 及Hmin 值单独及联合诊断DPN 的AUC 均>0.71，有一定诊断价值，且联合诊断价值更高。

当cut-off 值分别取49.370、5.465、31.370时，可获得最佳诊断价值。

结论Hmin 、Fchd 及Hmin 单独及联合检测对诊断DPN 具有较高的价值，且以联合诊断价值更高。
