| The aim of this study was to investigate the pulmonary parameters (spirometry and impulse oscillometry) of patients with Parkinson disease (PD) and healthy control peers, comparing the values of the subjects that were participating or not on a physiotherapeutic assistance program. Thirty-seven subjects were divided into four groups: two were formed by patients with PD (practitioners and non-practitioners of a physiotherapeutic protocol performed twice a week during 6 months) and the other two groups were formed by control peers (practitioners and non-practitioners of the same therapeutic protocol). The subjects underwent evaluation of chest cirtometry, spirometry and impulse oscillometry, being all the PD patients evaluated on the "off" state of their anti-PD medication. Data analysis occurred through the use of the non-parametric test of Kruskal-Wallis, with pairwise comparisons being done with Dunett T3 tests. Significance was set at 5%. Regarding
