Continuously for six hours daily over a period of four weeks, including weekend, all patients will be remained with complete immobilization of the non paretic upper limb. For this, an arm sling with the shoulder in adduction and internal rotation, elbow flexed at 90º, wrist and fingers in neutral position, made specifically for each patient will be used. They will be advised to use the restriction during their daily activities and instructed to remove it every hour for 10 minutes to perform stretching, which has been previously taught by the researchers to avoid functional deterioration caused by disuse. All muscle groups of the upper extremity will be stretched. A guide with instructions of the stretching will be distributed to patients. The patients will be instructed to take the immobilization on every day at same hour the tDCS sessions. In addition, the patients will be allowed to take the arm sling off during activities in which safety would be compromised, such as toileting, dressing, and bathing.
