| Objective：To investigate the effects of surface electromyogram biofeedback (sEMGBF) and neuromuscular electrical stimulation (NMES) combined with basic swallowing training on dysphagia after stroke and quality of life. Methods：A total of 120 patients with dysphagia after stroke who were admitted to our department between June 2018 and December 2019 were selected and divided into three groups by random number table method: basic swallowing rehabilitation training group (group A), neuromuscular electrical stimulation combined with swallowing rehabilitation training group (group B) and sEMGBF combined with swallowing rehabilitation training group (group C), with 40 cases in each group. Water swallow test classification and clinical efficacy were compared among the three groups before and after treatment, and the results of sEMG ［submental muscle group electromyographic signal (average amplitude, swallowing time limit)］, swallowing function ［Standardized Swallowing Assessment (SSA)］ and quality of life ［Swallowing Quality-of-Life Questionnaire (SWAL-QOL)］ were observed before and after treatment. Results：As compared with before treatment, the water swallow test classification in the three groups was improved after treatment (P<0.05), and the classification in group B and group C was better than that in group A (P<0.05). The total effective rate of treatment in group C was higher than that in group B and group A (P<0.05), and that in group B was higher than that in group A (P<0.05). After 3 months of treatment, the average sEMG amplitude and SWAL-QOL score in the three groups were higher than those before treatment, and the swallowing time limit was shorter than that before treatment, and the SSA score was lower than that before treatment (P<0.05). Further pairwise comparison showed that the above indicators in group C were better than those in group B and group A, and the indicators in group B were better than those in group A (P<0.05). Conclusion： Both sEMGBF and neuromuscular electrical stimulation can significantly improve the swallowing function and quality of life of patients with dysphagia after stroke, and the efficacy of sEMGBF is better than neuromuscular electrical stimulation. |
