Research On The Effects Of Diaphragm Relaxation Combined With Resistance Breathing Training On Respiratory,Motor And Balance Function Of Stroke Survivors

Objective: Resistance breathing training is a commonly used training method for stroke patients in clinical rehabilitation.It is mainly conducted through a device with a threshold resistance valve to adjust the resistance during breathing training.However,due to the limitations of expensive equipment and professional technology,this training method cannot be widely promoted in the home rehabilitation exercise of stroke patients after discharge,therefore,it is necessary to help patients find an economical and convenient home rehabilitation training means.Diaphragmatic relaxation is a hands-free breathing training technique for diaphragmatic function,which is simple,practical and not limited by equipment and instruments.However,there are few studies on the effect of this technique on the body function of stroke patients,and further studies are needed to demonstrate the effect of this technique on the function of stroke patients.Resistance breathing training is a commonly used training method for stroke patients in clinical rehabilitation.It is mainly conducted through a device with a threshold resistance valve to adjust the resistance during breathing training.However,due to the limitations of expensive equipment and professional technology,this training method cannot be widely promoted in the home rehabilitation exercise of stroke patients after discharge,which has a certain impact on the maintenance and consolidation of rehabilitation efficacy during hospitalization.Diaphragm relaxation is a hands-free breathing training technique for diaphragm function.It is simple and practical to operate and is not limited by equipment and instruments.However,the effect of this technique on motor function of stroke patients is not known at present,and the effect of this technique on the function of stroke patients needs to be further demonstrated.Therefore,the purpose of this study was to analyze the effects of diaphragm relaxation(DR)combined with resistance breathing training(RBT)on respiratory,motor and balance function in stroke patients.It provides basic reference and theoretical basis for the extension of this method to home rehabilitation exercise for stroke patients.Methods: In this study,60 patients with cerebral apoplexy in rehabilitation department of Zhengzhou Central Hospital were recruited as the research objects,and randomly divided into group A,group B and group C.Group A received routine rehabilitation training,diaphragmatic relaxation and resistance breathing training,group B received routine rehabilitation training and diaphragmatic relaxation,and group C received routine rehabilitation training and resistance breathing training.Maximal inspiratory pressure(MIP),Peak inspiratory velocity(PIF),Fugl-Meyer Motor Function Assessment(FMA),10 m Walking test(10MWT),Berg Balance Scale(BBS),and Limits of stability(LOS)of all subjects were collected before intervention,4 weeks,8 weeks and 12 weeks,and the data results were statistically analyzed.SPSS23.0 statistical software was used to analyze the data.Normal distribution test and homogeneity test of variance were performed on all data.t test was used for data with normal distribution and rank sum test was used for data with non-normal distribution.One-way repeated measurement ANOVA was used to compare the inter-group data with the data at different time nodes in the group.Spearman grade correlation coefficient test was used for the correlation between the data variables.All test types were set as double-tail tests,and α value of significance level was set as 0.05.P value less than 0.05 indicated significant difference,and P value less than 0.01 indicated extremely significant difference.Result: 1.Before intervention,there were no significant differences in basic data,MIP,PIF,FMA,10 MWT,BBS and LOS among group A,B and C(P > 0.05).2.After experimental intervention,MIP,PIF,FMA,BBS and LOS in groups A,B and C were significantly increased(P < 0.05),while 10 MWT were significantly decreased(P < 0.05)at 4,8 and 12 weeks.3.After experimental intervention,MIP,PIF,FMA,10 MWT,BBS and LOS were significantly different among groups A,B and C at 4,8 and 12 weeks(P < 0.05).The MIP,PIF,FMA,BBS and LOS of group A were higher than those of groups B and C,and the 10 MWT of group A was lower than that of groups B and C(P < 0.05).The MIP,PIF,FMA,BBS and LOS of group C were higher than those of group B,and the 10 MWT of group C was lower than that of group B(P < 0.05).4.After experimental intervention,MIP of the subjects was significantly correlated with 10 MWT,BBS and LOS(r=-0.73,r=0.74,r=0.65).There was significant correlation between 10 MWT and BBS and LOS(r=-0.71,r=-0.49).There was significant correlation between BBS and LOS(r=0.67).Conclusion: Compared with the two training methods alone,the diaphragm relaxation method combined with anti-resistance breathing training has a better effect on the promotion of respiratory,motor and balance function of stroke patients than the diaphragmatic relaxation method.Diaphragm relaxation and anti-resistance breathing training can improve the respiratory function of stroke patients,promote the recovery of limb motor and balance function,and improve the exercise ability.Diaphragm relaxation can be used as a choice of rehabilitation exercise for stroke patients at home.
