All patients will perform 60 minutes of intervention, twice a week, for six weeks. During the intervention, the patient will be positioned seated in a chair with a table in front of him and a mirror (50cm x 50cm) will be placed vertically between his upper extremity.

The patient's paretic upper extremity will be positioned behind the mirror, allowing only the movements of his healthy upper extremity to be visualized. The reflective side of the mirror will be facing the healthy upper extremity , the patient will perform the exercises observing the movements of his healthy upper extremity through the reflection produced by the mirror, interpreting as the movement of his paretic member.

All patients will perform 60 minutes of intervention, twice a week, for six weeks. The mirror will be placed in the same position as the intervention group. However, the subject will have access to the non-reflective side of the mirror, directly visualizing the movement of his healthy arm. In the control group, the patients will be submitted to the same bimanual activities of the intervention group, but without the reflecting side of the mirror. Thus, the nonreflective side of the mirror will be facing the healthy arm, the patient will perform the same exercises visualizing only the movement of the healthy member.

The exercise protocol will be composed of bimanual activities, performed by both the hands of the patient (paretic and healthy). The same protocol will be applied for both groups (intervention group and control group).

Initially, the desensitization of the limbs will be accomplished by brushing the skin with objects of different textures (sponge, brush, cloths). Afterwards, isolated exercises of fingers (flexion-extension, opposition), wrists (flexo-extension), forearms (prono-supination) and elbows (flexo-extension) and functional exercises such as cleaning a table with a cloth, tightening sponges, roll balls. Each exercise will be performed slowly and repeated for 15 times, totaling three series of each exercise. The protocol used will be based on the proposal of Rothgangel and Braun (2013). The intervention will be carried out by the author of the project and by students of scientific initiation.

The Fugl-Meyer motor assessment scale - FMAS - upper extremity section will be applied to measure the motor function of the paretic limb. In the motor domain, the tendon reflexes, synergistic movements, coordination and velocity of the upper limb are evaluated. It also includes evaluation of wrist movements and five types of grip. It consists of a cumulative numerical scoring system that evaluates the motor function of the upper extremity. Each item has three possible scores: 0 (not performed); 1 (partially accomplished) and 2 (fully realized). The total score ranged from 0 to 66 points, with scores ranging from 58-64 reflect mild impairment, 39-57 moderate impairment, and values below 39 show severe impairment.

The Fugl-Meyer Sensory Rating Scale - FMAS - upper extremity section will be applied to measure the sensory function of the paretic limb. Sensation is assessed as absent, deficient or normal for light touch and proprioception. This evaluation considered the shoulder, elbow, wrist and thumb. Each item has three possible scores: 0 (anesthesia); 1 (hypoesthesia or anesthesia) and 2 (normal). A total score ranged from 0 to 12 points, a higher score indicate a better sensory function.

Box and Block Test (BBT) - Functional upper limb test - will be applied to evaluate the gross dexterity manual. The test consists of moving, one by one, the largest possible number of blocks from one box to the other of the same size. The recorded score will be equivalent to the number of blocks moved from side to side in 60 seconds.
