Summary

People with Parkinson's disease (PD) experience various motor and nonmotor symptoms throughout its evolution. It is characterized mainly by the presence of tremor, stiffness, bradykinesia and postural instability, leading to progressive functional limitation and impairment in the performance of usual activities of daily living. In addition, patients may have cognitive disorders, memory deficits, problems related to visuospatial dysfunction, difficulties in performing sequential or repetitive movements, freezing, and slow psychological responses. Previous studies analyzed by systematic reviews suggest the efficacy of Transcranial Direct Current Stimulation (tDCS) to improve the motor and non-motor symptoms of PD, depending on the area of stimulation. However, most of these focus only on one specific area. Therefore, the overall objective of this study is to investigate the effects of multifocal neuromodulation on the motor and cognitive function of people with Parkinson's disease.

Conditions

  • Parkinson Disease

Interventions

DEVICE

Transcranial Direct Current Stimulation

Participants will receive 15 sessions of Transcranial Direct Current Stimulation (tDCS) for 20 minutes each at 2 mA intensity, 5 times a week. The current will be delivered via saline-embedded sponge surface electrodes using a battery-powered neurostimulator (TCT-Research, Trans Cranial Technologies, Hong Kong). A small active specific electrode (5x5 cm) will be used to prevent coverage of adjacent areas, resulting in a current density of 0.08 mA / cm². These parameters are within the safe limits established in previous human studies.
