Home-based monitoring of pulmonary function in patients with Duchenne muscular dystrophy

This study examined the feasibility of home-based monitoring of pulmonary function over a 12-month period in patients with Duchenne muscular dystrophy aged 10–18 years who were enrolled in a randomized, placebo-controlled, Phase III trial. Home-based PEF was measured weekly using the Vitalograph Asma-1 peak flow meter, and was compared with in-hospital PEF measured at weeks 13, 26, 39, and 52 using a Vitalograph Pneumotrac spirometer.
