 The spinal cord injury is identified as the major cause of permanent disability worldwide, with the loss of ability to walk being the largest and most devastating of them for these patients. Therefore, our goal is to analyze the effects of the treatment with electrical transcranial direct-current stimulation tDCS associated with gait training with partial body weight support aided by robotic device Lokomat, Hocoma in the gait of patients with incomplete spinal cord injury SCI classified as AIS C and D. In this stratified randomized double-blind study, the participants will be randomly allocated into one of both groups, outpatients GA or inpatients GI, and will receive active or placebo tDCS followed by gait training with Lokomat GA: 3 sessionsweek x 10 weeks 30 sessions; GI: 5 sessionsweek x 6 weeks 30 sessions. The functional assessments through clinical and functional scales, assess gait, muscle strength, spasticity, balance and pain and neurophysiological cortical excitability measured by transcranial magnetic stimulation, electroencephalography and functional near-infrared spectroscopy will be held before and after the training period. The functional assessments will be also held after 15 sessions intermediate and after 3 months follow up. The expected result is that patients that received the active tDCS presents an improvement over the ground gait after the Lokomat training period, significantly greater than the placebo group, with positive correlation between neurophysiologic, kinematics and functional measurements.
