Continuous Chest Wall Vibration in COPD Rehabilitation

Status Completed

Clinical Trial Summary

Dyspnea, the sensation of breathing discomfort or shortness of breath, is one of the main symptoms for patients affected by Chronic Obstructive Pulmonary Disease (COPD), particularly during exercise. Previous study show that chest wall vibration decrease dyspnea in COPD patients and precisely when applied during the inspiration phase, called "in-phase vibration" (IPV) which provide vibration directly on intercostal muscles. These findings have been obtained in laboratory context and the intercostals muscles vibration has been tested only in single phases of breathing, during inspiration with IPV and during exhalation with out-of-phase vibration (OPV). None study has evaluated the effect of a continuous chest wall vibration (CCWV), namely muscles vibration during the whole cycle of breathing, on dyspnea in patients with COPD in a clinical context. Continuous high frequency vibration has been proven to reduce myoelectrical manifestation of fatigue, probably modifying the centrally driven motor unit recruitment hierarchy, in healthy subjects.

Moreover, CCWV is a modality of provide vibration more suitable and cost-effective in a clinical context than single-phases vibration that requires specific instruments for the detection of breathing phases and the coupling with vibration device.

On these bases, the investigators hypothesized that CCWV at high frequency, applied during a cycle ergometer training program, could decrease dyspnea and enhance the exercise tolerance in COPD patients. Therefore, the aim of this study is to evaluate the effects of high frequency CCWV on dyspnea and exercise tolerance in patients with COPD patients compared to usual care and to sham intervention.
