Clinical efficacy of transcutaneous auricular vagus nerve stimulation in treatment of lum-bar disc herniation
Objective To investigate the clinical effect of transcutaneous auricular vagus nerve stimulation(TaVNS)in the treatment of lumbar disc herniation(LDH).Methods A total of 68 LDH patients who were treated in the Department of Traditional Chinese Medicine of No.971 Hospital of PLA Navy from January 2022 to December 2022 were selected as the study objects,and were divided into conventional treatment group and TaVNS group according to random number table method,with 34 cases in each group.The conventional treatment group received traditional Chinese medicine treatment,while the TaVNS group received TaVNS on the basis of the conventional treatment group for 2 courses.The VAS pain scores and Japanese Orthopedic Association(JOA)scores of the two groups were recorded before treatment(T0),on the 7th day(T1),and on the end of treatment(T2),and were compared and ana-lyzed to judge the improvement of symptom.Results After treatment,VAS scores and JOA symptom scores were significantly improved compared with before treatment,and the difference was statistically significant(F=366.978,P<0.001;F=400.187,P<0.001).At T2,the VAS score of the TaVNS group was significantly lower than that of the conventional treatment group at T2(2.24±0.99 vs 2.79±0.88,P=0.016).The JOA symptom score of the TaVNS group at T2 was significantly higher than that of the conventional treatment group(21.38±4.59 vs 18.56±3.36,P=0.005).The improvement index and clinical efficacy of TaVNS group were better than those of conventional treatment group,and the differences were statistically significant(Z=3.325,P=0.001).Conclusions TaVNS can obvi-ously improve the clinical symptoms of patients with lumbar disc herniation,which is worthy of popularization and application.
