Lung volume reduction surgery and pulmonary rehabilitation improve exercise capacity and reduce dyspnea during functional activities in people with emphysema.
OBJECTIVE
The purpose of this study was to examine the therapeutic effects of lung volume reduction surgery (LVRS) and pulmonary rehabilitation on levels of dyspnea during functional activities in patients with diffuse emphysema.


METHODS
Fifteen subjects who had undergone LVRS participated in this study. A visual analog scale (VAS) Activity Dyspnea Scales (VADS) measurement tool developed for this study was determined reliable in 10 subjects. The VADS was used to assess changes in dyspnea with functional activity in 10 subjects prior to and following the interventions of LVRS and pulmonary rehabilitation.


RESULTS
RESULTS of this study indicate that LVRS followed by pulmonary rehabilitation significantly reduces levels of dyspnea during functional activities.


CONCLUSIONS
The VADS developed for this study is a valid and reliable method of assessing changes in levels of dyspnea during functional activities in the LVRS population.
