INTRODUCTION: Parkinson's disease (PD) is a neurodegenerative disease that affects the central nervous system, characterized by the loss of dopaminergic neurons in the brainstem, mainly in the substantia nigra region. Its main clinical signs are stiffness, bradykinesia, tremor at rest and postural instability. In addition, due to disease progression, respiratory symptoms and complications deserve special attention because they present a high mortality rate. OBJECTIVE: To evaluate the acute effects of contraction maneuvers in thixotropic modality of inspiratory muscles on thoracic wall volumes in patients with PD. In a randomized cross-sectional study. METHODS: 18 patients with PD were evaluated to participate in the study. 14 patients with PD (9H, 5M) were included in the study. All were evaluated for pulmonary function, respiratory muscle strength, chest wall volume variation before and after contractions in the thixotropic modality of inspiratory muscles, residual volume novel (RV) and total lung capacity (TLC). As a control, the same maneuver was used, replacing the contraction of the inspiratory muscles with apnea. The order of accomplishment of the maneuvers were randomized and were carried out with a washout period of 7 days. RESULTS: Our results showed that in the apnea group there was a significant increase in end expiratory volume EEV values in the CW (p = 0.0010) and RCp (p = 0.0002) compartments, as well as end inspiratory volume (EIV) values increased in the CW compartments (p = 0, 0179) and RCa (p = 0.0486) after performing the maneuvers starting from TLC. After the maneuvers starting from the RV, the apnea group presented a significant decrease in EEV only in the RCp compartment (p = 0.0431) and the contraction group did not present a significant response to this type of maneuver. CONCLUSION: Our results suggest a tendency of increased chest wall volumes after thixotropic maneuvers from TLC, especially in the pulmonary rib cage and abdominal in apnea, and pulmonary rib cage in the inspiratory contraction. On the other hand, a decrease in EEV after performing the maneuvers starting from VR, to the chest wall in the apnea maneuver.
