Effect of ice stimulation combined with electrical muscle stimulation in the treatment of dysphagia after stroke
This work was supported by the Scientific Research Project of Sichuan Provincial Health Committee (19PJ045) and Deyang Applied Technology Research and Development Fund Project (JYCX20160086), China.
Objective: To observe the effect of pharyngeal ice stimulation combined with low-frequency pulse electrical stimulation in the rehabilitation of patients with dysphagia after stroke. Methods: A total of 168 cases of patients with dysphagia after acute stroke were selected as subjects. According to the order of admission, the subjects were divided into 3 groups (n=56 for each) by random number table. The control group was given conventional swallowing training, while the electrical stimulation group was given muscle electrical stimulation on the basis of the control group, the combined stimulation group was given ice stimulation on the basis of the electrical group. The intervention time was 2 weeks. The efficacy of treatment, Standardized Swallowing Assessment (SSA), Swallowing Quality-of-Life Questionnaire (SWAL-QOF), and incidence of pneumonia were compared between the 3 groups. Results: The total effective rates of the 3 groups were 76.4% (the control group), 96.4% (the electrical stimulation group) and 98.1% (the combined stimulation group), respectively., with statistically significant difference (P<0.01). The incidence of pneumonia was 34.5% (the control group), 17.9% (the electrical stimulation group) and 14.8% (the combined stimulation group), respectively (P<0.01). After the intervention, the scores of swallowing function and quality of life in the combined stimulation group were better than those in the control group, and the difference was statistically significant (P<0.01). Conclusion: Pharyngeal ice stimulation combined with low-frequency pulse electrical stimulation can effectively improve the rehabilitation efficiency, swallowing function, and significantly reduce the incidence of pneumonia, improve the quality of life of patients with dysphagia after stroke.
