The currently accepted definition classifies Cerebral Palsy (CP) as a mere posture andmovement disorder. Conversely, some authors have recently associated the presence of several motordysfunctions exhibited by diplegic children with CP to an impairment in the perceptive system. Theaim of the present study was to investigate the influence of the Perceptive Impairment (PI) on motorcontrol and to appraise if the PI can be revealed by a reaching task.A functional reach and touch experiment was accomplished from sitting posture considering differentdirections and distances. Typically developing and diplegic children with CP were enrolled and, thelatter, a priori divided in two subgroups considering a positive or negative diagnosis of PI. Thereaching trials were quantified by means of centre of pressure analysis in terms of the overall qualityof the task, and accuracy and effectiveness of postural adjustments and Anticipatory PosturalAdjustments (APAs).The three groups showed statistically significant differences in terms of percentage of touched target,and of time spent and maximum distance covered to reach the target. In particular, PI caused a majordifficulty in accomplishing the reaching tasks, thus a lower autonomy level in action. Overall, the PIstrongly affected the anticipatory control system. Children with PI, rarely recruited APAs, each ofwhich was characterized by small amplitude and inaccuracy in direction. The lack of effective APAsindicated how PI strongly influenced the motor control strategy.The present study demonstrates that the PI is a primary syndrome responsible for the long-termprognosis beside the motor and the postural disorders in CP
