ABSTRACT

Objective To investigate the difference in EMG peroneal nerve conduction velocity between patients with diabetic foot ulcers and T2DM patients without diabetic foot and its influencing factors.Methods Retrospective analysis was performed on clinical data of a total of 108 patients, including 54 inpatients with diabetic foot and 54 T2DM patients without diabetic foot ulcers, so as to investigate the difference in EMG peroneal nerve conduction velocity between these two groups of patients and its influencing factors.Results Compared with the control group, EMG peroneal nerve conduction velocity was slower in the diabetic foot group, with statistically significant difference (P<0.05).There were significant differences in education attainment, WBC count, neutrophil ratio, hemoglobin, albumin, and ABI between the two groups (P<0.05).Peroneal sensory nerve conduction velocity presented negative correlation with HbA1C, WBC count, and neutrophil ratio(P<0.05), and positive correlation with fasting C-peptide level, hemoglobin, albumin, and ABI (P<0.05).Peroneal motor nerve conduction velocity presented negative correlation with smoking duration, HbA1C, and neutrophil ratio (P<0.05), and positive correlation with hemoglobin and albumin (P<0.05).Conclusion Diabetic perineuropathy is an important risk factor for diabetic foot ulcers.Poor blood glucose control, infection, smoking, poor pancreatic islet function, anemia, hypoproteinemia, and poor lower limb blood supply may contribute to the development or progression of diabetic perineuropathy.In preventing and treating diabetic foot, it is therefore desirable to lay stress on blood glucose control, give active anti-infective treatment, improve or protect pancreatic islet function, and correct anemia and hypoproteinemia;attention should also be paid to patient education on diabetes and foot diseases.
