Abstract:
Objective:To evaluate the effect of combining contralateral high-frequency transcranial magnetic stimulation (rTMS) with biofeedback-controlled empty swallowing training on dysphagia among stroke survivors.Methods:Eighty dysphagic stroke survivors were divided at random into a control group, a biofeedback group, an rTMS group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the biofeedback group and the rTMS group received empty swallowing training based on biofeedback or high-frequency rTMS applied to the healthy motor cortex as appropriate. The combined treatment group was given both. The treatment was administered once daily, 5 days a week for 3 consecutive weeks. Before and after the treatment, all of the subjects′ swallowing was evaluated using the penetration aspiration scale (PAS), functional oral intake scale (FOIS) and a standardized swallowing assessment (SSA). The latency and amplitude of the mylohyoid muscle′s motor evoked potentials (MEPs) were also recorded before and after the treatment.Results:After the treatment, significant improvement was observed in the average PAS, FOIS and SSA scores as well as in the latency and amplitude of the MEPs in the four groups. The average results in the combined treatment group were significantly better than in the other 3 groups. The latency of the mylohyoid muscle′s MEP was significantly shorter in the combined group than in the control and biofeedback groups on average, while the amplitude was significantly greater than in the control group.Conclusion:Combining contralateral high frequency rTMS with empty swallowing training based on biofeedback can better improve the swallowing of dysphagic stroke survivors.
