Abstract:
Objective To explore the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on activity in the intact motor cortex controlling the suprahyoid muscles and thus on dysphagia after an unilateral stroke.Methods Forty patients suffering dysphagia more than two weeks after a unilateral cerebral stroke were randomly divided into an experimental group and a control group,each of 20.Both groups were given traditional swallowing rehabilitation training,while the experimental group was additionally provided with 5 Hz rTMS for two weeks.Before and after the treatment,all of the patients were characterized using X-ray fluoroscopy,video fluoroscopic swallowing study (VFSS) and surface electromyography,and their swallowing was evaluated using a standardized swallowing assessment (SSA) and a penetration-aspiration scale (PAS).Results After the treatment,significant improvement was observed in both groups in the average swallowing time and in the maximum amplitude of sEMG,as well as the average SSA,PAS and VFSS scores (P＜0.05).The average values in the experimental group were in all cases significantly better than the control group's averages (P＜0.05).Conclusion Applying rTMS at 5 Hz to the motor cortex of the contralateral hemisphere controlling the suprahyoid muscles can effectively improve unilateral-hemisphere dysphagia after stroke.
