1. Study objective To evaluate the effect of robotic-assisted gait training combined with transcranial direct current stimulation (tDCS) as compared to that of robotic-assisted gait training on gait function of chronic stroke patients 2. Subjects chronic stroke patients with gait impairment 3. Methods * Group 1: Robotic-assisted gait training with anodal tDCS (45 min) * Group 2: Robotic-assisted gait training with sham tDCS (45 min) * Duration of treatment: 2 weeks, 5 times a week * Evaluation: Baseline, 1 day after the treatment, 4 weeks after the treatment

tDCS will be applied on the primary motor cortex of the lower limb in the impared hemisphere before robotic-assisted gait training. Anodal tDCS will be applied with an intensity of 2mA for 20 min. Sham tDCS will be applied with an intensity of 2mA just for 1 min, after which the current will be slowly tapered down to 0 over a several seconds.
