Cerebral palsy is the commonest cause of motor disability. Under this term are grouped people with special educational needs, who have in common a persistent disorder of tone and movement due to a non-progressive brain injury. Although cerebral palsy affects muscle movement, it is not caused by problems in the muscles or the nerves, but by abnormalities in brain impairing its ability to control movement and posture. In order to assess the influence of activities for the prefunctional motor deficit of manual abilities in patients with cerebral palsy, a therapeutic intervention was applied to 15 patients (7 men and 8 women) who had motor disorders in upper limbs. A quasi experimental 60 days study, conceived by 2 hours daily treatment was carried out. Initial and final qualitative functional scales of hands were applied to compare results. This novel therapeutic system influenced positively in the recovery of lost abilities as was statistically demonstrated.
