Objective To analyze the effect of low-frequency electrical stimulation combined with swallowing training on the rehabilitation effect of patients with dysphagia after cerebral infarction. Methods: Sixty-four patients with cerebral infarction diagnosed and treated in our hospital from March 2022 to March 2024 were selected as the research subjects. The patients were randomly divided into the control group and the observation group, with 32 cases in each group. The control group received conventional swallowing training, while the observation group received low-frequency electrical stimulation combined with swallowing training. The activity of the hyoid laryngeal complex (hyoid upward displacement, hyoid forward displacement, thyroid cartilage upward displacement, distance of thyroid cartilage forward displacement), swallowing function [Swallowing Function Assessment Scale (SSA)] and quality of life [Specific Dysphagia Quality of Life Scale (SWAL-QOL)] of the two groups before the intervention and 4 weeks after the intervention were analyzed and compared. Results: After 4 weeks of intervention, the upward displacement of the hyoid bone, forward displacement of the hyoid bone, upward displacement of the thyroid cartilage, and the distance of forward displacement of the thyroid cartilage in both groups were significantly increased compared with those before the intervention. Moreover, the upward displacement of the hyoid bone, forward displacement of the hyoid bone, upward displacement of the thyroid cartilage, and the distance of forward displacement of the thyroid cartilage in the observation group after the intervention were significantly longer than those in the control group (P < 0.05). After 4 weeks of intervention, the SSA scores of both groups were significantly lower than those before the intervention, and the SSA score of the observation group was significantly lower than that of the control group (P < 0.05). After 4 weeks of intervention, the SWAL-QOL scores of both groups were significantly increased compared with those before the intervention, and the SWAL-QOL score of the observation group was significantly higher than that of the control group (P < 0.05). Conclusion: For patients with dysphagia after cerebral infarction, receiving low-frequency electrical stimulation combined with swallowing training can improve the activity of the hyoid laryngeal complex and swallowing function of the patients, and enhance the quality of life.
