Parkinson’s disease, transcranial direct current stimulation, physical therapy, dual-task
INTRODUCTION: Parkinson's Disease (PD) is a neurodegenerative disorder that affects motor and cognitive functions, so these patients with this disease have difficulties in performing dual-task activities, a condition present in everyday life. It is possible that strategies such as Transcranial Direct Current Stimulation (tDCS) can be associated with motor training enriched with dual-task training to improve the performance of two simultaneous tasks. OBJECTIVE: To verify the effect of a dual task protocol, involving motor and cognitive tasks, associated with transcranial direct current stimulation on mobility and kinematic variables in individuals with Parkinson's Disease. MATERIALS AND METHODS: Fifty-six patients with Parkinson's disease will be recruited to participate in this multicenter, double-blind, randomized clinical trial. Patients in the modified Hoehn & Yahr stage 1.5 to 3, aged between 40 and 70 years, will be included. The subjects will be randomly distributed in an experimental group (EG) and a control group (CG). The EG will perform treadmill gait training associated with dual-task exercises+tDCS, while the CG will perform only treadmill gait training+tDCS. Blinded testers will assess patients before and after 12 intervention sessions and after a 4-week follow-up period. EXPECTED RESULTS: it is expected to obtain positive results with the application of the protocol in this population, aiming to improve the daily conditions in the motor and cognitive aspects with the use of tDCS.
