ABSTRACT
Objective To explore the effect of Occupational Therapy in Group on cognitive function of children with March to cerebral palsy, and to observe the evaluation results of P300 of event-related potentials on cognitive function. Methods 40 children with spastic cere-bral palsy from March to September, 2015, were divided into control group (n=20) and observation group (n=20). Both groups received rou-tine rehabilitation training, and the observation group received Occupational Therapy in Group additionally, for 3 months. They were as-sessed with Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and P300 of event-related potentials before and after treatment. Results The latency of P300 shortened after treatment (t>7.778, P5.808, P0.461, P5.944, P<0.001), and was higher in the observation group than in the control group (t=-3.472, P=0.001). Conclusion Occupational Ther-apy in Group could further improve the cognitive function of children with spastic cerebral palsy. P300 can be used as an assessment tool for cognitive function.
