Inspiratory Muscle Training for Asthmatic Patients: A Meta-Analysis of Randomized Controlled Studies

Abstract

Introduction The efficacy of inspiratory muscle training (IMT) for asthma control remains controversial. We conduct a systematic review and meta-analysis to explore the influence of IMT on asthma control.

Methods We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through May 2020 for randomized controlled trials (RCTs) assessing the efficacy of IMT for asthma control. This meta-analysis is performed using the random-effect model.

Results Six RCTs are included in the meta-analysis. Overall, compared with control group for asthma, IMT can remarkably increase MIP (SMD=3.32; 95% CI=1.73 to 4.91; P<0.0001) and decrease dyspnea scores (SMD=−0.77; 95% CI=−1.34 to −0.21; P=0.007), but has no obvious effect on FEV1 (SMD=0.36; 95% CI=−0.74 to 1.45; P=0.52) or FVC (SMD=2.09; 95% CI=−0.70 to 4.89; P=0.14).

Conclusions IMT may benefit to the treatment of asthma.

Zusammenfassung

Hintergrund Die Wirksamkeit des inspiratorischen Muskeltrainings (IMT) auf die Asthmakontrolle ist nach wie vor umstritten. Wir führten eine systematische Übersichtsarbeit und Meta-Analyse durch, um den Einfluss von inspiratorischem Muskeltraining auf die Asthmakontrolle zu untersuchen.

Methoden Die Datenbanken PubMed, EMbase, Web of science, EBSCO und Cochrane Library bis Mai 2020 wurden nach randomisierten kontrollierten Studien (RCTs) zur Wirksamkeit von inspiratorischem Muskeltraining auf die Asthmakontrolle untersucht. Diese Meta-Analyse wurde unter Verwendung des Random-Effekt-Modells durchgeführt.

Ergebnisse Sechs RCTs wurden in die Meta-Analyse eingeschlossen. Insgesamt kann das inspiratorische Muskeltraining im Vergleich zur Kontrollgruppe bei Asthma den maximalen inspiratorischen Druck (MIP) deutlich erhöhen (SMD=3,32; 95% CI=1,73 bis 4,91; P=0,14).

Schlussfolgerungen Inspiratorisches Muskeltraining kann bei der Behandlung von Asthma eine positive Wirkung haben.
