Safety, tolerability and efficacy of LEGA-Kid® mechanical percussion device versus conventional chest physiotherapy in children: a randomised, single-blind controlled study.

Children receiving either manual or mechanical CPT showed improvements in respiratory distress symptoms with no adverse effects. A combined strategy of nebulised hypertonic saline followed by CPT for LRTI removes airway secretions and results in improvements of moderately severe respiratory distress. The LEGA-Kid mechanical CPT method was superior in reducing RR.
