Parkinson's disease (PD) is the second most common neurodegenerative disease in the world, considering the central nervous system disorders that affect movement. In addition to motor impairment, the literature reinforces changes in ventilatory parameters, such as restrictive lung dysfunction, obstructive airway disease, and upper airway obstruction. Pulmonary disorders are more evident in patients in later and advanced stages of PD, and are responsible for most of the morbimortalities resulting from the disease. Objectives: To evaluate the effects of a protocol of diaphragmatic awareness, in association with the global exercises, on the pulmonary function of individuals with Parkinson's disease. Methods: This is an experimental, uncontrolled clinical trial. Participants are patients with Parkinson's disease referred for care at the UEAFTO / CER-II UEPA neurofunctional outpatient clinic whose records will be consulted for the collection of epidemiological data and postural assessment of cognitive functions through protocol Montreal Cognitive Assessment (Brazilian experimental version) and classification by modified Hoehn and Yahr scale. Those who meet the inclusion criteria will be evaluated through the evaluation form, Pulmonary Functional Status and Dyspnea Questionnair protocol, submitted to Pulmonary Function Test and respiratory muscle strength assessment by Spirometry and Manovacuometry, respectively. They will be submitted to an intervention protocol prepared by the physiotherapy team of UEPA's Elderly Care Center for 20 sessions lasting 60 minutes twice a week, consisting of global exercises and diaphragmatic awareness, being re-evaluated in the 10th and 20th sessions. The protocol used will be registered in the Clinical Trials database. All participants will sign a Free and Informed Consent Form and the research will be submitted to analysis by the Human Research Ethics Committee of the University of the State of Pará (UEPA). The data collected will be tabulated in a Microsoft Excel 2016® worksheet for further statistical analysis using BioEstat® 5.3 software. Expected results: obtain an improvement in the variables related to pulmonary function in the experimental group after the application of the intervention protocol and in relation to the control group.
