Abstract：Objective To analyze the relationship between the changes in plantar pressure and nerve conduction ve-locity in patients with diabetic foot.Methods A total of 90 patients with diabetic foot admitted to our hospital from May 2021 to October 2023 were retrospectively selected as the research subjects.According to whether nerve conduction abnormal-ities occurred,the patients were divided into the non-occurrence group(n=48)and the occurrence group(n=42).The plantar pressure parameters of the two groups were compared.The Pearson correlation coefficient was used to analyze the correlation between plantar pressure and nerve conduction velocity abnormalities.Multivariate Logistic regression analysis was performed to identify the influencing factors of nerve conduction abnormalities in patients with diabetic foot.Results The plantar contact area,maximum pressure value(PP),and pressure-time integral(PTI)in the occurrence group were all higher than those in the non-occurrence group(t/P=27.046/＜0.001,32.842/＜0.001,27.560/＜0.001).The conduction velocities of the medi-an nerve,ulnar nerve,peroneal nerve,radial nerve,and tibial nerve,as well as the F-wave conduction velocities in the occur-rence group were all lower than those in the non-occurrence group(t/P=9.872/＜0.001,8.921/＜0.001,8.563/＜0.001,9.125/＜0.001,10.214/＜0.001,8.347/＜0.001,7.986/＜0.001,8.023/＜0.001,9.012/＜0.001,8.765/＜0.001).Pearson's test showed that the plantar contact area,PP,and PTI were all positively correlated with nerve conduction velocity abnormalities(r/P=0.789/＜0.001,0.715/0.002,0.802/＜0.001).The results of multivariate Logistic regression analysis showed that the increases in plantar contact area,PP,and PTI were all independent risk factors for nerve conduction abnormalities in patients with diabetic foot[OR(95％CI)=2.690(1.864-2.967),2.401(1.933-3.013),2.474(1.847-2.842)].Conclusion The plantar contact area,PP,and PTI are the main factors contributing to nerve conduction abnormalities in patients with diabetic foot.Clinicians should pay attention to patients with diabetic foot whose above indicators are elevated.
