Effects of rTSMS Associated With Treadmill Training in Patients With Parkinson's Disease

The primary objective is to evaluate the effects of treadmill gait training associated with repetitive transspinal magnetic stimulation on the change in rapid gait speed in Parkinson Disease patients. The investigators hypothesize that the association of repetitive transspinal magnetic stimulation with treadmill gait training should be superior to treadmill gait training alone in improving gait symptoms in patients with PD. Additionally, will be investigated the effects of treadmill gait training associated with repetitive transspinal magnetic stimulation on comfortable gait speed; in clinical and neurophysiological measures; in motor symptoms; in activities of daily living; in the ability to walk (total distance covered); in balance performance; in time to complete the turn; in the severity of the freezing of the gait; in mobility; in the level of physical activity; in the number and fear of falls and in the perception of quality of life of patients with PD. In addition, the possible side effects of the intervention will be evaluated.
