Ambulatory chest physiotherapy in mild-to-moderate acute bronchiolitis in children under two years of age - A randomized control trial.

The study had a high dropout rate, particularly in the control group (52.6% vs 23.8% in the intervention group), which introduces potential bias. The intervention was delivered by a single highly specialized physiotherapist, so results may not generalize to all practitioners. Blinding was not possible, and assessments were performed by different clinicians for each group after the emergency department phase, which could influence the scoring. The study population was restricted to mild-to-moderate cases eligible for discharge, so findings do not apply to severe cases requiring hospitalization.

The study was approved by the Ethics Committee of CHUSJ. No specific funding sources or author conflicts of interest were declared in the provided text.

Do not interpret this as evidence that classical chest physiotherapy (clapping, vibration) is effective, as this study tested specific modern techniques. The high dropout rate and lack of blinding mean the positive result should be viewed as preliminary evidence requiring confirmation in larger, more robust trials.
