Effect of high-frequency transcranial magnetic stimulation combined with rehabilitation training on surface electromyography in patients with dysphagia after stroke
Objective To explore the effect of high-frequency transcranial magnetic stimulation(TMS)combined with rehabilitation training on surface electromyography(sEMG)in patients with dysphagia after stroke.Methods 100 patients with dysphagia after stroke admitted to our hospital from January 2022 to January 2023 were randomly divided into an observation group and a control group with 50 patients in each group.The control group received routine swallowing rehabilitation training,while the observation group received high-frequency TMS treatment on the basis of the control group.The clinical efficacy of the two groups was compared,and the watian drinking water test grade and the scores of the standard swallowing function assessment scale(SSA)and the dysphagia severity assessment scale(DOSS)were evaluated at the same time.In addition,the maximum amplitude value of the upper and lower hyoid muscle groups and the swallowing duration of the two groups were measured,and finally the swallowing quality of life questionnaire(SWAL-QOL)scores of the two groups were evaluated.Results The total effective rate of 96.00%in the observation group was significantly higher than 82.00%in the control group,with a statistically significant difference(χ2 =5.005,P<0.05).The improvement in the evaluation level of the depression test after treatment in the two groups was significantly better than before treatment,and the observation group was significantly better than that in the control group,with a statistically significant difference(Z=4.157,P<0.05).After treatment,the SSA score of the two groups was lower than before treatment,and the DOS score was higher than before treatment,and the SSA score of the observation group was lower than the control group,and the DOS score was higher than the control group,with a statistically significant difference(t=6.192,5.676,P<0.05).After treatment,the maximum amplitude values of the superior and inferior hyoid muscle groups in both groups were significantly higher than before treatment,and the swallowing duration was shorter than before treatment,and the maximum amplitude values of the superior and inferior hyoid muscle groups in the observation group were significantly higher than in the control group,the swallowing duration was shorter than in the control group,with a statistically significant difference(t=9.038,9.790,3.022,4.693,P<0.05).The SWAL-QOL scores of the two groups after treatment were significantly higher than before treatment,and the SWAL-QOL scores of the observation group were significantly higher than those of the control group,with a statistically significant difference(t=26.258,P<0.05).Conclusion An increase in high-frequency amplitude values can increase the excitability of brain neurons in patients with swallowing disorders after stroke,cause more neurons to emit action potentials,promote connections and information transmission between neurons.This not only effectively improves clinical symptoms and swallowing function of patients,but also improves the maximum amplitude values of the superior and inferior hyoid muscle groups,swallowing duration,and quality of life.
