Respiratory training with a specific device in cystic fibrosis: A prospective study

Introduction: Chest physiotherapy (CP) is used in cystic fibrosis (CF) even if there is no robust scientific evidence of a beneficial effect. We investigated the effects of a training with a specific device (SpiroTiger (R)) in a group of CF patients. This device, developed for respiratory training through maximal inspirations and espirations without hypocarbia, may improve respiratory function and mucus clearance. Patients where instructed and trained by a physiotherapist with individualized settings of training parameters.Methods: Twenty-four patients were enrolled in an open-label 1 year observational study. Baseline and post intervention measurements were determined by king function (FVC, FEV1, FEF 25-75), patients' opinions on physiotherapy (questionnaires), need for antibiotic treatment (clinical follow-up and records) and perception of physical fitness (questionnaires) in the year before and in the year of intervention. Adherence to physiotherapy was monitored by means of a specific device software.Results: Increased lung function (FEV1 p<0.01), perception of physical fitness (p<0.001) and a reduction in the need for intravenous antibiotic treatment (p<0.001) were reported. Adherence to treatment was good/acceptable in 92% of patients.Conclusions: This Study shows an association between training through a specific device and improved lung function. Further trials are needed to confirm this report. (C) 2007 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.
