The Application Of Different Intensity Inspiratory Muscle Training In Stroke Patients With Hemiplegia

Research Purpose:This study aims to explore the intervention effects of different inspiratory muscle training on inspiratory muscle function,lung function,motor function,and ability of daily living in stroke patients with hemiplegia;at the same time to verify the intervention effect of high-intensity inspiratory muscle training in stroke patients with hemiplegia The safety and effectiveness.Research Methods:From January 2020 to January 2021,78 patients with hemiplegia after stroke in the rehabilitation department of a tertiary hospital in Huzhou City,Zhejiang Province were selected as the research objects.According to the random number table method,the patients were divided into control group（group A）,medium intensity group（group B）and high intensity group（Group C）,with 26 in each group.The three groups of patients all received routine treatment,routine rehabilitation and routine care in the rehabilitation department.On this basis,groups B and C received medium-intensity and high-intensity inspiratory muscle training,once a day,5-7 days a week,for a total of continuous intervention 6 weeks.The maximum inspiratory pressure（MIP）,peak inspiratory flow（PIF）,forced vital capacity（FVC）and forced expiratory volume in one second（FEV₁）were measured by repeated measurement analysis of variance before intervention and at the 2nd,4th and 6th week of intervention;Fugl-Meyer assessment（FMA）and modified Barthel Index（MBI）were evaluated by one-way ANOVA before and 6 weeks after the intervention.Research Results:（1）During the intervention of this study,2 cases were lost to follow-up,and 76 patients were finally enrolled.The general data of the three groups were not statistically significant（P>0.05）.There were no adverse events in the three groups of patients during the intervention period.（2）Inspiratory muscle function:There was no significant difference in MIP and PIF among the three groups before intervention（P>0.05）.Intra group comparison:there was no significant difference in group A after intervention for 2 weeks,4 weeks and 6 weeks（P>0.05）;Group B,group C patients with intervention for 4 weeks,6 weeks compared with before intervention,the difference was statistically significant（P<0.05）.Comparison between groups:after 2 weeks of intervention,there was no significant difference in MIP and PIF among the three groups（P>0.05）;After 4 weeks of intervention,there were significant differences in MIP and PIF among the three groups（P<0.05）.The improvement effect of MIP and PIF in group B and group C was higher than that in group A;After 6 weeks of intervention,there were significant differences in MIP and PIF among the three groups（P<0.05）.The improvement degree of group C was higher than that of group B and group A.（3）Lung function:There was no significant difference in FVC and FEV₁among the three groups before intervention（P>0.05）.Intra group comparison:there was no significant difference in group A after intervention for 2 weeks,4 weeks and 6 weeks（P>0.05）;Group B,group C patients with intervention for 4 weeks,6 weeks compared with before intervention,the difference was statistically significant（P<0.05）.Comparison between groups:after 2 weeks of intervention,there was no significant difference in FVC and FEV₁among the three groups（P>0.05）;After 4weeks of intervention,there were significant differences in FVC and FEV₁among the three groups（P<0.05）.The improvement effect of FVC and FEV₁in group B and group C was higher than that in group A;After 6 weeks of intervention,there were significant differences in FVC and FEV₁among the three groups（P<0.05）.The improvement degree of group C was higher than that of group B and group A.（4）Motor function:After 6 weeks of intervention,the FMA scores of the three groups were higher than before the intervention,and the difference was statistically significant（F=5.518,P<0.05）.The scores of groups B and C were higher than those of group A（P<0.05）.（5）Activities of daily living:After 6 weeks of intervention,the MBI scores of the three groups of patients were higher than those before the intervention,and the difference was statistically significant（F=6.662,P<0.05）.The scores of groups B and C were higher than those of group A（P<0.05）Research Conclusion:（1）Inspiratory muscle training can improve the inspiratory muscle function、lung function、motor function、daily living ability in stroke patients with hemiplegia,and the effect of high-intensity improvement is better.（2）High-intensity inspiratory muscle training has a better effect on improving the inspiratory muscle function and lung function of stroke patients with hemiplegia,and it is safe and effective.
