Clinical Trial with two groups, transcranial direct current stimulation aplication and sham; triple blinded. The protocol is applied 5 consecutive days during the training of a manual dexterity task. Manual dexterity and somatosensory variables are measured pre intervention, post one day of intervention, post 5 days of intervention, and 5 days after finish the intervention.
Clinical Trial with two groups, transcranial direct current stimulation aplication (1 mA ) and sham (ramp up and down of 30 seconds in total) . Bouth interventions will last 20 minutes; at the same time of the aplication bouth are going to train the manual dexterity with Purdue Pegboard Test. This protocol is applied 5 consecutive days, also it have a follow up of 5 days more. It is triple blinded. Manual dexterity and somatosensory variables are measured pre intervention, post one day of intervention, post 5 days of intervention, and 5 days after finish the intervention.
