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) 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 lung 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.
