Peak Cough Flow and Cough Clearance in Patients With Muscular Dystrophy
Pilot Study of Cough Peak Flow And Airway Clearance in Pediatric Patients With Neuromuscular Disease
This study is to determine whether physiologic measures (peak cough flow, measures of respiratory muscle strength including MIP, MEP ,SNIP, and spirometry) can predict spontaneous cough clearance (as measured by a nuclear medicine study) in children with neuromuscular disease. It will also determine whether airway clearance is augmented by high frequency chest wall oscillation.
