Abstract:
Objective To investigate the diagnostic value of the medial plantar nerve in diabetic peripheral neuropathy(DPN).Methods A retrospective analysis was conducted in 114 patients with type 2 diabetes mellitus in our hospital.All the participants were divided into DPN group(n=73)and type 2 diabetes mellitus(T2DM)group(n=41)based on the presence of peripheral nerve damage.Simultaneously,35 healthy volunteers were chosen as the normal control(NC)group.General data,biochemical indexes,medial plantar nerve amplitude,conduction velocity,and abnormal rates were compared among the three groups.DPN patients were further divided into symptomatic and asymptomatic groups based on the presence of plantar paresthesia symptoms.The abnormal rate of the medial plantar nerve was compared with that of the superficial peroneal nerve and sural nerve in each group.Receiver operating characteristic(ROC)curve analysis was employed to assess the diagnostic value of the medial plantar nerve in DPN.Results The amplitude of the medial plantar nerve was significantly lower[(3.00±1.42)vs(6.64±3.76)vs(6.51±3.58)μV],the conduction velocity was markedly reduced[(46.57±7.42)vs(49.42±6.96)vs(51.22±5.34)m/s],and the abnormality rate was elevated(87.67%vs 12.20%)in T2DM group,than in NC groups(P<0.05).Spearman correlation analysis indicated a negative correlation between the medial plantar nerve amplitude and HbA1c(r=-0.267,P<0.05),while the conduction velocity showed a negative correlation with age(r=-0.157,P<0.05).In both symptomatic and asymptomatic DPN patients,the abnormal rate of the medial plantar nerve was higher than that of the superficial peroneal nerve and sural nerve(P<0.05).The area under the ROC curve was 0.942,signifying a reliable diagnostic value for DPN using the medial plantar nerve(P<0.05).Conclusions The medial plantar nerve proves valuable in the diagnosis of DPN,exhibiting higher sensitivity than the superficial peroneal nerve and sural nerve.
