| Objective: To observe the clinical efficacy of low-frequency repetitive transcranial magnetic stimulation (rTMS) acting on the healthy hemisphere and high-frequency rTMS acting on the affected hemisphere combined with electromyographic (EMG) biofeedback therapy in patients with post-stroke dysphagia (PSD). Methods: A total of 100 stroke patients were randomly divided into the control group and the experimental group with 50 patients in each group. Both groups were all treated with routine medication and swallowing rehabilitation training, the control group was treated with EMG biofeedback training and sham rTMS, and the experimental group was treated additionally with rTMS and EMG biofeedback training. The low-frequency of rTMS acting on the healthy hemisphere was 1 Hz, and the high-frequency of rTMS acting on the affected hemisphere was 10 Hz. The swallowing function of patients was evaluated by the water swallowing test, and the Rosenbek Penetration-Aspiration Scale (PAS) and the functional oral intake scale (FOIS). The swallowing quality of life scale (SWAL-QOL) was used to evaluate the patients’ swallowing quality of life. The clinical efficacy of the two groups was evaluated at the end of treatment. Results: After 2 weeks of treatment regimens, the total effective rate was 93.88% in the experimental group, and 73.47% in the control group (P<0.05). The scores of swallowing function and quality of life in the two groups were significantly improved as compared with those before treatment (P<0.05). The scores of PAS, FOIS and SWAL-QOL in the experimental group were better than those in the control group (P<0.05). The water swallowing test in the experimental group was better than in the control group after treatment. Conclusion: The rTMS acting on the bilateral brain combined with EMG biofeedback can improve the swallowing function and swallowing quality of life of stroke patients. |
