To address this uncertainty, we performed a randomized controlled trial to assess the effects of a 4-week rehabilitation program including breathing retraining on pulmonary function (PFT), cardio-pulmonary exercise capacity (CPET), health related quality of life (HRQL) and cardiac autonomic modulation (CAM).
A randomized controlled trial comparing the effects of a conventional 4-week pulmonary rehabilitation program with those of a 4-week pulmonary rehabilitation program plus breathing retraining on pulmonary function (FEV1), cardiopulmonary exercise capacity (6-minute walking distance, 6MWD), health related quality of life (chronic respiratory questionnaire, CRQ) and cardiac autonomic function (rMSSD) was performed.
