Functional assessments will be carried out according to a protocol exploring the three fields of the ICF. Impairments will be evaluated by the score of Quality of Upper Extremity Skills Test (14), MACS (13), and the Box and Block test (15). Then, spasticity (with two scales), kinematics and strength of the paretic arm will be evaluated using the modified Ashworth and Tardieu scales, the ReaPLAN robot and a dynamometer, respectively (9, 16, 17). Disability will be evaluated via Abilhand-kids (18) and Pediatric Evaluation of Disability Inventory (19). Participation restrictions will be evaluated via the MHAVIE questionnaire (20). All assessments will be carried out by a occupational therapist, which will be not informed the group that the child is assigned (single-blind). All rehabilitation and assessment sessions will be conducted at the IRAHM.
