Abstract:
Objective:To explore the effect of inspiratory muscle training(IMT)on respiratory function,psychological well-being,and sleep in patients recovered from corona virus disease 2019(COVID-19)infection.Method:Seventy-six adults who had recovered from COVID-19 between February and June 2023 at the depart-ment of rehabilitation medicine of the fourth medical center of the PLA general hospital,with a massive inspi-ratory pressure(MIP)of less than 70%were selected for this study.The participants were randomly divided into the control group(n=38)and the experimental group(n=38).The control group received conventional re-habilitation training,while the experimental group underwent an additional 4-week IMT program on top of con-ventional rehabilitation.Respiratory function including maximum massive inspiratory pressure(MIP),forced expi-ratory vital capacity(FVC),forced expiratory volume in the first second(FEV1),forced expiratory volume/forced vital capacity in the first second(FEV1/FVC),and peak expiratory flow rate(PEF),were measured be-fore and after the 4-week intervention.Psychological status and sleep quality were assessed using the Hamilton depression scale(HAMD),the Hamilton anxiety scale(HAMA)and Pittsburgh sleep quality index(PSQI).Result:After 4 weeks of intervention,the MIP,FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI im-proved in both control and experimental group compared with pre-intervention.The MIP,PEF,and PSQI in the experimental group were significantly better than pre-intervention(P<0.05);the control group showed sig-nificant improvement in MIP,FVC,FEV1,HAMA,and PSQI compared to pre-intervention(P<0.05).After 4 weeks of intervention,the MIP and PEF in the experimental group were significantly better than those in the control group(P<0.05);there was no significant difference in FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI between the two groups(P>0.05).Conclusion:IMT can effectively improve the respiratory function,physical and mental health of patients recov-ered from COVID-19,making it an effective rehabilitation strategy for post-COVID-19 recovery.
