      In daily practice, it remains a challenge to find an optimal effective therapy regarding these outcomes. With great interest, I read the article by Pancera er al

      Effectiveness of continuous chest wall vibration with concurrent aerobic training on dyspnea and functional exercise capacity in patients with chronic obstructive pulmonary disease: a randomized controlled trial.
      about the findings of their innovative randomized trial to investigate the effect of continuous chest wall vibration (CCWV). The authors conclude that CCWV might provide additional benefits on functional exercise capacity compared with usual care. In this letter, I would like to raise a number of concerns on the assumptions made in this study.
