, and control (n ؍ 25). The participants underwent anthropometric and cirtometric measurements associated with maximal respiratory pressures. We analyzed data using descriptive (mean and SD) and inferential statistics (1-way analysis of variance, Student t test, and Scheffé post hoc) with a level of significance of 5% (P < .05) and a CI of 95%. RESULTS: Although the anthropometric and cirtometric variables indicated similarity of values between groups (P > .05), the maximal inspiratory and expiratory pressures were considerably lower in the subjects with PD and AD (P < .01). CONCLUSIONS: The control of the anthropometric and cirtometric variables of the subjects indicates that RMS is affected by the aging process, and its decline increases in neurodegenerative conditions. This fact represents a serious risk for the development of atelectasis and other pneumo-functional complications, which must be considered in proposing of future therapies.
| 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
Background Parkinson's disease (PD) causes a series of movement disorders, many of them starting in the early stage. Objective To analyze the pulmonary function of mild-stage subjects with PD and to investigate the effects of levodopa on it. Methods We included 21 patients with idiopathic PD and 20 healthy control subjects. The participants were submitted to spirometry and impulse oscillometry assessments. The PD patients were evaluated during the “off” and “on” phases of their anti-PD medication, which was was converted to levodopa in an equivalent daily dose. A statistical analysis was performed with cross-sectional (PD patients “off” medication versus controls) and paired (PD patients “off” medication versus PD patients “on” medication) tests. The effect of levodopa was calculated with partial Eta-squared (η2 ρ). Significance was set at 5%. Results The PD patients presented normal values in the impulse oscillometry. Regarding spirometry, the results indicated an incipient obstructive ventilatory disorder in the PD group – confirmed by patients' flow-volume curves. The PD patients received a daily dose of 354.7 ± 148.2 mg of levodopa. The paired analyses showed a small effect of anti-PD medication on pulmonary parameters (η2 ρ = 0.197 for spirometry and η2 ρ= 0.043 for impulse oscillometry). Conclusion Patients with PD in the mild stage of the disease present pulmonary compliance and resistance compatible with normal parameters. The differences regarding the spirometric results indicate an incipient obstructive ventilatory disorder in patients with PD. Levodopa had small effect on pulmonary function in the mild stage of the disease.
