- Abstract
Objective: To investigate the diagnostic value of electromyography in asymptomatic diabetic peripheral neuropathy (DPN). Methods: 142 patients with type 2 diabetes mellitus (T2DM) who were treated in our hospital from January 2020 to December 2022 were selected. According to whether they were accompanied by DPN, the patients were divided into DPN group (n=68) and simple T2DM group (n=74). All patients underwent nerve muscle point map detection, including nerve conduction (NCS), F wave and H reflex detection. The EMG parameters and abnormal rates of NCS, F wave and H reflex were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of NCS abnormality, F wave abnormality, H reflex abnormality and their combination for DPN. Results: Compared with T2DM group, the distal motor latency (DML) of median nerve and ulnar nerve in DPN group was significantly increased (P<0.05), and the compound muscle action potential was significantly decreased(P < 0.05). At the same time, the sensory conduction parameters of sensory conduction velocity (SNCV) and sensory nerve action potential (SNAP) in DPN group were lower than those in simple T2DM group (P<0.05). Compared with T2 DM group, the mean latency (Fmean) and F wave dispersion (Fchd) of ulnar nerve and posterior tibial nerve in DPN group were significantly prolonged (P< 0.05). The shortest latency (Hmin) of posterior tibial nerve in DPN group was significantly longer than that in T2DM group (P< 0.05). The abnormal rates of NCS, F wave and H reflex in DPN group were significantly higher than those in T2 DM group (P< 0.05). ROC curve analysis showed that the areas under the curve of NCS, F wave and H reflex in the diagnosis of DPN were 0.659, 0.614 and 0.671, respectively. The AUC of the combination of the three was 0.753, which was significantly higher than that of each single index (P< 0.05). Conclusion: Electromyography plays an important role in the diagnosis of asymptomatic DPN. The combined detection of NCS, F wave and H reflex is helpful to improve the early diagnosis of DPN.
