Effect of neuromuscular electrical stimulation combined with swallowing rehabilitation training on post-stroke dysphagia and its effect on movement of the hyo-laryngeal complex

Objective To evaluate the effect of neuromuscular electrical stimulation combined with swallowing rehabilitation on post-stroke dysphagia and its effect on movement of the hyo-laryngeal complex. Methods Total 56 patients with post-stroke dysphagia from January,2016 to January,2017 were randomly divided into observation group and control group(n=28).The general data,results of the drinking water test,grapevine grade,VFSS swallowing dysfunction score,and hyoid and laryngeal complex of the two groups were observed and compared. Results After the treatment,the results of the drinking water test in the two groups were significantly higher than those before the treatment(P<0.05),and the water level of the observation group was significantly higher than that of the control group(P<0.05).The effective rate of the observation group was significantly higher than that of the control group(P<0.05).The results of the two groups were significantly higher than those before treatment(P<0.05),and the results of the observation group were significantly higher than those of the control group(P<0.05).The effective rate of the observation group was significantly higher than that of the control group(P<0.05).The scores of VFSS swallowing dysfunction were significantly improved in both groups after the treatment(P<0.05),and the score of VFSS swallowing dysfunction in the observation group was significantly higher than that in the control group(P<0.05).When the diet was swallowed,the distance between the hyoid bone and the uplift of the hyoid were significantly increased in the observation group(P<0.05).There was no significant difference in the movement of thyroid cartilage before and after the treatment in the observation groups(P>0.05).There was no significant difference in the movement of hyoid bone and thyroid cartilage before and after the treatment in the control group(P>0.05). Conclusion NMES combined with swallowing function can improve the clinical symptoms of dysphagia after stroke and the muscle strength of the mylohyoid and geniohyoid muscle,and effectively restore the swallowing function.
