The purpose of this study is to improve hand function combining transcranial direct current stimulation (tDCS) and innovative interactive hand robotic training in people with chronic SCI. We also aim to investigate the mechanisms of the motor recovery and to characterize the neurophysiological profile of patients and specif i c muscles that respond to robotic motor training by using Transcranial Magnetic Stimulation (TMS).
The combined tDCS and hand robotic training is a 6-week program that includes 3 sessions per week, each session lasting approximately 1 hour (18 sessions total). The hand robotic training will be preceded by 20 min anodal 2mA tDCS or sham stimulation. The participants will be evaluated before, after and in a 1 month follow-up. Participants will be assessed on clinical/functional evaluation, TMS and robotic kinematics.
