Objective: to explore the effect of balloon dilatation combined with low-frequency electrical stimulation on dysphagia in brainstem infarction. Methods: A total of 60 cases were included in this study. They were divided into group 1 and group 2, which were respectively the observation group and the control group. The former was treated with combined therapy, while the latter was treated with separate therapy. Results: according to the results in Table 4 and Table 5, the results of each index in the observation group are better than those in the control group, indicating that the combination therapy and the single therapy are more advantageous, and the comparison with P < 0.05 is statistically significant. Conclusion: balloon dilation combined with low-frequency electrical stimulation has a significant effect on dysphagia in brainstem infarction. Compared with simple swallowing function training, balloon dilation can improve patients' swallowing function, which is worthy of research and promotion. 展开更多
