| Objectives:Objective to observe the effects of short-term IMT on inspiratory muscle function,pulmonary function,arterial oxygen pressure,dyspnea index and activities of daily living in stroke patients at convalescence stage.To evaluate the effect of short-term IMT on the recovery of respiratory function and the daily living ability in patients with stroke recovery.Methods:80 hospitalized patients with stroke were randomly collected.The patients were divided into two groups according to whether the patient had respiratory diseases:Pulmonary disease group(A group,n=24)and Non-pulmonary disease group(B group,n=56);pulmonary disease group patients were divided again for the Training group(A-1 group,n=12)and the Control group(A-2 group,n=12),the non-pulmonary disease group was also divided into training group(B-1 group,n=28)and control group.The training group(A-1 group,B-1 group)received a 4-week inspiratory muscle training in addition to the conventional treatment;the control group(A-2 group,B-2 group)only receive regular treatment.All patients received MIP,PIF,FVC,Pa02,Borg dyspnea scale and Barthel index(MBI)Evaluation.Results:1.In patients with pulmonary disease(group A)after 4 weeks of treatment,patients in the training group(group A-1)had inspiratory muscle capacity(MIP,PIF),pulmonary function(FVC),Borg score,and partial arterial oxygen pressure(Pa02)improvement was significantly higher than that of the control group(A-2 group)(P<0.05),but there was no significant difference in Barthel index between the two groups(P>0.05).2.In the non-pulmonary disease group(B group)patients after 4 weeks of treatment,the training group(B-1 group)patients in the inspiratory muscle capacity(MIP,PIF),pulmonary function(FVC),Borg score improved compared to the control group(There was a significant difference in group B-2(P<0.05),but there was no significant difference in Pa02 and Barthel index between the two groups after treatment(P>0.05).3.After treatment for 4 weeks in the two training groups(A-1 and B-1),the therapeutic effect only showed significant differences inarterial oxygen pressure(PaO2)(P<0.05).4.After treatment for 4 weeks in the two control groups(A-2 and B-2 groups),the treatament effect only showed a significant difference in arterial oxygen pressure(Pa02)and forced vital capacity(FVC)(P<0.05).Conclusions:1.Inspiratory muscle training can significantly improve the inspiratory muscles,lung function,and dyspnea of inpatients with stroke,but it does not improve the partial pressure of oxygen and daily living ability in patients with stroke.2.Inspiratory muscle training can significantly improve the inspiratory muscles,lung function,dyspnea and blood oxygen pressure in stroke patients with respiratory disease,but it does not improve the patient’s ability to perform daily activities.3.For inspiratory inpatients undergoing inspiratory muscle training,the presence of respiratory disease affects the effect of inspiratory muscle training only on the difference in arterial oxygen partial pressure improvement.Inspiratory muscle training for stroke with respiratory disease The arterial blood oxygen tension improved better in patients.4.For inpatients with stroke who do not perform inspiratory muscle training,the presence of respiratory disease can significantly affect the patient’s blood oxygen tension and forced vital capacity improvement. |
