Digital High-Intensity Respiratory Muscle Training on COPD Patients

This single-blinded randomized controlled trial is to determine effect of Digital High-intensity Respiratory Muscle Training delivered through the Sonmol electronic respiratory muscle trainer on ventilatory function and functional capacity in patients with chronic obstructive pulmonary diseases (COPD) It articulates the clinical rationale by explaining how airflow limitation is caused by COPD and chest hyperinflation, or dysfunction of respiratory muscles, and describes why specific, intense exercise training of muscles of inspiration or expiration may correct or prevent these conditions. This trial within current evidence supporting respiratory-muscle training and highlights the potential advantages of digital delivery-real-time feedback, adjustable resistance, gamification, and remote monitoring-to boost adherence and training specificity in a rehabilitation context. The study compares digital high-intensity respiratory muscle training plus conventional pulmonary rehabilitation to conventional pulmonary rehabilitation alone to see if the digital training provides additional benefits.
