About this trial
This is a prospective clinical study to evaluate the efficacy of tDCS stimulation, coupled with conventional rehabilitation, on the development of post-stroke neuropathic pain.
The study involves a double-blind, randomized, sham-controlled experimental protocol involving 2 parallel groups with patients allocated according to a Fleming design (40 patients in the active group, 20 patients in the control group).
The study is aimed at sub-acute post-stroke patients. After recruitment, they will receive 10 sessions of tDCS stimulation (2mA, 20 minutes with a current on/off ramp of 0.1 mA/s). For the control group, stimulation will stop after the current ramp.
