Functional patch combined with surface electromyographic biofeedback for post-stroke dysphagia / 中国组织工程研究

ABSTRACT

BACKGROUND: Studies have shown that functional patch has a long-lasting effect on the treatment of dysphagia, and surface electromyographic biofeedback has also been confirmed to relieve dysphagia. OBJECTIVE: To analyze the clinical efficacy of functional patch combined with surface electromyographic biofeedback in patients with dysphagia after stroke. METHODS: One hundred patients with dysphagia after stroke were randomly divided into a control group, a functional patch group, a surface electromyographic biofeedback group and a combined treatment group (functional patch plus surface electromyographic biofeedback), each group containing 25 patients. The therapeutic effects were compared between groups by repetitive saliva swallowing test, video fluoroscopic swallow study and clinical efficacy evaluation before, 1 and 2 months after treatment. The implementation of the study protocol complied with the relevant ethical requirements of the First Affiliated Hospital of Jinzhou Medical University (approval No. 201918), and informed consent was obtained from all patients and their families prior to the initialization of the study. RESULTS AND CONCLUSION: After treatment, there was an increasing trend in the repetitive saliva swallowing test, a decreasing trend in the video fluoroscopic swallow study, and a significant improvement in the clinical efficacy in each group (P < 0.05). Compared with the control group, significantly increased frequency of saliva swallowing, significantly shortened time of epiglottis movement during swallowing and significantly improved clinical benefit rate were observed in the functional patch, surface electromyographic biofeedback group and combined treatment groups (all P < 0.05). More significant improvements in the above-mentioned indexes were observed in the combined treatment group (P < 0.05). These findings indicate that both functional patch and surface electromyographic biofeedback have certain curative effect on dysphagia after stroke, and the combination of the two therapies has better clinical effect.
