INTRODUCTION: The limitations imposed by cerebral palsy lead to persistence of disorders of movement and posture, therefore postural control plays an important role, since the ability to maintain postural orientation is fundamental to perform activities of daily living. OBJECTIVES: To investigate the use of visual information in postural control of children with cerebral palsy (CP) and neurologically normal children (NN). MATERIALS AND METHODS: We evaluated eight children with diplegic CP and eight NN children of both genders, aged 6 to 12 years old, as they remained standing still inside of a moving room in the following experimental conditions: no movement of the room with eyes open and eyes closed during movement of the 30s and 60s in the room for frequencies 0.2 and 0.5 Hz. Registration of movements of the room and children was performed by active markers fixed on the front wall of the room, and on the trunk between the scapulae of children, through the OPTOTRAK system. RESULTS: Children with CP swayed more than NN children in the two movement conditions of the room, and all children swayed more with no vision than with vision on the condition that the room was moved. Moreover, the movement of the moving room influenced children with PC and NN and similarly all children were influenced by the frequency at which the room has been moved. CONCLUSION: Children with CP and NN are influenced by the manipulation of visual information during maintenance of upright stance and by the frequency at which the visual stimulus is presented.
