| Objective: To explore the efficacy of progressive resistance inspiratory muscle training on lung function and diaphragm function in stroke patients, and to provide a basis for promoting respiratory rehabilitation in stroke patients. Methods: A total of 118 stroke patients were selected for the study and randomly divided into the control group (n=59) and the experimental group (n=59). The control group was given conventional respiratory training (abdominal lip-contraction breathing training, percussion expectoration training, thoracic release training), and the experimental group was given progressive resistance inspiratory muscle training for 30 min every time, twice a day, and 6 days every week for 4 weeks. The pulmonary ventilation indexes of the 2 groups before and after intervention were compared: forceful lung volume (FVC), forceful expiratory volume in the first second (FEV1), FEV1/FVC with peak expiratory flow (PEF); inspiratory muscle function: maximal inspiratory pressure (MIP); diaphragm function: diaphragm thickness at the end of inhalation (DTei), diaphragm thickness at the end of exhalation (DTee), diaphragm thickening rate (DTF) and diaphragm mobility profile. Results:After intervention, all pulmonary ventilation indexes (FVC, FEV1, FEV1/FVC, PEF) and inspiratory muscle function (MIP) in the 2 groups were better than those before treatment, and at the same time, those in the experimental group were significantly better than in the control group (P<0.001); DTei, DTF and diaphragm mobility in the 2 groups were higher than those before treatment, and all of the above diaphragm functions in the experimental group were significantly better than in the control group (P<0.05). However, there was no statistically significant difference in the intergroup comparison of DTee after treatment in the 2 groups. Conclusion: Progressive resistance inspiratory muscle training improves lung function and diaphragm function more significantly than conventional respiratory training in stroke patients. |
