Efficacy of respiratory tele-rehabilitation in COPD patients: Systematic review and meta-analysis.

Pulmonary rehabilitation (PR) is a proven and effective intervention for chronic obstructive pulmonary disease (COPD). The recent pandemic has raised interest on new services, such as telerehabilitation (Tele-R). The aim of this study was to systematically review the effects of Tele-R in COPD on: 1) exercise capacity evaluated by the 6-minute walk test (6MWT); 2) dyspnea (modified Medical Research Council - mMRC); 3) COPD control (the COPD assessment test - CAT).
