〔Abstract〕 Objective To explore the effect of respiratory function training on dysphagia after stroke. Methods A total of 70 stroke patients with dysphagia admitted in Ruizhou Hospital from January 2018 to January 2019 were selected and randomly divided into control group and observation group, with 35 cases in each group. The control group received conventional swallowing function training treatment, and the observation group received respiratory function training on the basis of the control group. The efficacy of the two groups of patients, the swallowing function and respiratory function before and after intervention, and the incidence of aspiration pneumonia were compared and analyzed. Results The total effective rate of treatment in the observation group was higher than that in the control group, and the difference was statistically significant (P < 0.05). Before treatment, there was no significant difference in the scores of swallowing contrast examination (VFSS) and swallowing function assessment scale (SSA) between the two groups of patients (P > 0.05); After treatment, the VFSS scores of the two groups increased, while the SSA scores decreased. And the VFSS scores of the observation group were significantly higher than those of the control group, and the SSA scores were lower than those of the control group, the differences were statistically significant (P < 0.05). There was no significant difference in the forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) between the two groups before the intervention (P > 0.05); After the intervention, the FVC and FEV1 of the two groups were higher than those before the intervention , and the FVC and FEV1 of the observation group were higher than those of the control group, the differences were statistically significant (P < 0.05). The incidence of aspiration pneumonia in the observation group was lower than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Respiratory function training can help to improve the swallowing function and respiratory function of stroke patients with dysphagia, and it can also effectively reduce the incidence of aspiration pneumonia.
