Objective To investigate the effects of Mendelssohn′s techniques and feeding training on swallowing function in the elderly Parkinson′s disease patients with dysphagia. Methods A total of 104 elderly Parkinson′s disease patients with dysphagia admitted in No. 904 Hospital from January 2016 to February 2018 were enrolled in this study. According to treatment methods, they were divided into routine intervention group (control group, n=52) and Mendelssohn′s techniques and feeding training group (observation group, n=52). Their swallowing dysfunction and comfortableness were observed and compared before and after intervention, and the incidences of aspiration pneumonia and salivation and the severity of Parkinson′s disease after intervention were compared between the 2 groups. SPSS statistics 18.0 was used to analyze the data. Results After intervention, the proportions of dysphagia grade Ⅱ, Ⅲ and Ⅳ were 53.85% (28 cases), 32.69%(17 cases) and 13.46%(7 cases) respectively in the patients of the observation group, while were 32.69%(17 cases), 36.54%(19 cases) and 30.77%(16 cases) in those of the control group. Compared with the control group, the observation group had dysphagia significantly improved (Chi-square=2.479, P=0.013). After intervention, the patients had gradeⅠ,Ⅱ, Ⅲ and Ⅳ comfortableness accounting for 42.31% (22 cases), 28.85%(15 cases), 23.08%(12 cases)[JP+1] and 5.77%(3 cases) respectively in the observation group, which were superior to those in the control group[21.15%(11 cases), 23.08%(12 cases), 34.62%(18 cases) and 21.15%(11 cases)] with significant difference (Chi-square=3.057, P=0.002). The incidences of aspiration pneumonia [5.77% (3 cases) vs 25.00% (13 cases), Chi-square=5.983, P=0.005] and salivation[7.69% (4 cases) vs 28.85% (15 cases), Chi-square=7.792, P=0.000] were significantly lower in the observation group than the control group. After intervention, the patients with Parkinson′s disease in stages 1.0,1.5,2.0,2.5,3.0 and 4.0 were 22,3, 4,2, 1 and 0 case in the observation group, which were better than those in the control group (12,5, 8,4, 2,1 cases, respectively), and the difference was statistically significant (Chi-square= 2.432, P=0.015). Conclusion Mendelssohn′s techniques and feeding training are helpful to improve swallowing function, reduce the incidences of aspiration pneumonia and salivation, and improve patient′s comfortableness in the elderly patients with Parkinson′s disease and dysphagia.
