Deep Brain Stimulation in Parkinson's Disease: Motor and Functional Outcomes

Rövid összefoglaló (regiszter, angolul)

Introduction: Parkinson's Disease (PD) is a progressive neurodegenerative condition characterized by classic motor symptoms, such as bradykinesia, rigidity, resting tremor, and postural instability, which directly compromise the mobility and autonomy of individuals with PD. Furthermore, non-motor manifestations, including autonomic, cognitive, and emotional changes, impact the quality of life of individuals with PD. Deep Brain Stimulation (DBS) surgery is a well-established treatment to assist in improving the primary motor symptoms of PD; however, literature is scarce in describing specific results regarding physiotherapeutic aspects, such as the motor symptoms that determine better quality of life and social participation for individuals with PD. Determining whether factors amenable to improvement prior to surgery-such as bradykinesia, muscle strength, and balance-are related to better motor and functional outcomes in individuals with PD post-DBS is of great importance to ensure a better result from the surgical intervention. Objective: To compare motor outcomes (gait speed, balance, freezing of gait, fear of falling, muscle strength, functional capacity, and physical activity level) of individuals with PD after undergoing DBS, relative to the motor status previously observed in the preoperative period. Methods: This is an uncontrolled clinical trial, with data collection conducted at the Neurovida private multidisciplinary clinic and the Hospital Santa Casa in Belo Horizonte. This study will be registered at www.clinicalTrials.gov and conducted according to the Consolidated Standards of Reporting Trials (CONSORT) recommendations. The present study will be submitted to the Research Ethics Committee of the Federal University of Minas Gerais (COEP) and will only commence after proper approval. All necessary consents for the development of the study have been obtained. The sample consists of individuals with idiopathic PD selected by a clinical neurologist specializing in movement disorders. The inclusion criteria for the present study are: having idiopathic PD diagnosed for more than five years, being under treatment with a neurologist specializing in movement disorders, and having an indication for DBS. Descriptive statistics and normality tests will be performed for all study variables. Selected variables will be compared in terms of mean difference between post- and pre-surgery measurements, considering a 95% CI. In all analyses, a significance level of α=0.05 will be considered, using the SPSS statistical package version 15.0 for Windows.
