Effect Of Inspiratory Muscle Training On Cardiopulmonary Function In Stroke Patients

Research purpose:Through the intervention study of inspiratory muscle training on stroke patients,to observe the influence of inspiratory muscle training on the cardiopulmonary function of stroke patients,explore the application value of inspiratory muscle training in stroke patients.Research methods and contents:A total of 48 stroke patients in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine were selected and divided into 24 patients in the experimental group and 24 patients in the control group by random number table method.Before intervention,baseline data were collected for both groups,including gender,age,body mass index,stroke type,smoking history,alcohol consumption history,disease duration,and MMSE score.The control group received routine rehabilitation training for 6 weeks,6 times a week,30min each time.On the basis of the control group,the experimental group used the Power Breathe K5 inspiratory muscle training equipment for inspiratory muscle training for 6 weeks,12 times a week,twice a day,once in the morning and once in the afternoon,for 15 minutes each time.Before and after treatment,the muscle force index of inspiratory muscle,peak inspiratory flow rate(PIF),forced vital capacity(FVC),forced expiratory volume in the first second(FEV1),maximum gas volume per minute(MVV),peak oxygen uptake(VO2peak),maximum load,O2pulse and MBI score of the two groups were evaluated and compared.All indicators were evaluated by the same person.Statistical software SPSS statisticas 21.0 was used for statistical analysis,and P<0.05 was statistically significant.Research results:1.Before the experiment,the baseline data and observation indicators of the two groups were compared,and there was no significant difference between the indicators,which was comparable(P>0.05).2.After the experiment,the function of inspiratory muscle:After the intervention,the strength index of inspiratory muscle in the experimental group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was statistically significant(P<0.05),and the difference was statistically significant between the groups(P<0.001).The inspiratory peak flow rate in the experimental group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was not statistically significant(P>0.05),the difference between the groups was statistically significant(P<0.001).In terms of lung ventilation function,after the intervention,in the FVC group,the experimental group was better than before,the difference was statistically significant(P<0.001),the control group was better than before,the difference was not statistically significant(P>0.05),the difference was statistically significant(P<0.001).FEV1 intra-group comparison,the experimental group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was statistically significant(P<0.05),the comparison between groups,the difference was statistically significant(P<0.001).Within the MVV group,the experimental group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was not statistically significant(P>0.05),the difference between the groups was statistically significant(P<0.001).Cardiopulmonary endurance:After intervention,the peak oxygen intake in the experimental group was higher than before,the difference was statistically significant(P<0.05),while the control group was not significantly higher,the difference was not statistically significant(P>0.05).After intervention,the difference between groups was statistically significant(P<0.001).Within the maximum exercise load group,the test group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was not statistically significant(P>0.05).After intervention,the difference between groups was statistically significant(P<0.001).Before and after comparison in the oxygen pulse group,the experimental group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was not statistically significant(P>0.05),the experimental group was significantly higher than the control group,the difference was statistically significant(P<0.05).Ability of daily living activities:After intervention,the MBI score was compared before and after the group,the test group was higher than before,the difference was statistically significant(P<0.001),the control group was higher than before,the difference was statistically significant(P<0.05),and the MBI score of the test group was significantly higher than that of the control group,the difference was statistically significant(P<0.05).Conclusion:1.Inspiratory muscle training can improve cardiopulmonary endurance of stroke patients.2.Inspiratory muscle training can improve the function of inspiratory muscle in stroke patients.3.Inspiratory muscle training can improve the lung ventilation function of stroke patients.4.Inspiratory muscle training can improve the ability of daily living activities of stroke patients.
