We urgently need to identify safe and effective COVID-19 rehabilitative strategies. The aim of the current study was to investigate the potential rehabilitative role of inspiratory muscle training (IMT).\r\n\r\n**Methods**: 281 adults (age 46.6±12.2 years; 88% female) recovering from self-reported COVID-19 (9.0±4.2 months post-acute infection) were randomised 4:1 to an 8-week IMT or a \"usual care\" waitlist control arm. Health-related quality-of-life and breathlessness questionnaires (King's Brief Interstitial Lung Disease (K-BILD) and Transition Dyspnoea Index (TDI)), respiratory muscle strength, and fitness (Chester Step Test) were assessed pre- and post-intervention. The primary end-point was K-BILD total score, with the K-BILD domains and TDI being key secondary outcomes.\r\n\r\n**Results**: According to intention to treat, there was no difference between groups in K-BILD total score post-intervention (control: 59.5±12.4; IMT: 58.2±12.3; p\u003c0.05) but IMT elicited clinically meaningful improvements in the K-BILD domains for breathlessness (control: 59.8±12.6; IMT: 62.2±16.2; p\u003c0.05) and chest symptoms (control: 59.2±18.7; IMT: 64.5±18.2; p\u003c0.05), along with clinically meaningful improvements in breathlessness according to TDI (control: 0.9±1.7 versus 2.0±2.0; p\u003c0.05). IMT also improved respiratory muscle strength and estimated aerobic fitness.\r\n\r\n**Conclusions**: IMT may represent an important home-based rehabilitation strategy for wider implementation as part of COVID-19 rehabilitative strategies. Given the diverse nature of long COVID, further research is warranted on the individual responses to rehabilitation; the withdrawal rate herein highlights that no one strategy is likely to be appropriate for all.\r\n\r\n[Read the full study](https://pubmed.ncbi.nlm.nih.gov/35236727/)\r\n","category":1,"position":2,"created_at":"2024-07-15T09:26:38.324Z","updated_at":"2024-08-25T20:14:21.949Z","url":"https://www.pro2health.com/articles/1.json"}
