Abstract: Objective To study the correlation between intelligence and gross motor function for children with cerebral palsy. Methods 90 children with cerebral palsy (CP) were assessed with Gross Motor Function Classification System (GMFCS), Wechsler preschool and primary scale of intelligence (WPPSI), Wechsler intelligence scale for children (WISC-R) and analyzed statistically. Results The intelligence quotient (IQ) and verbal intelligence quotient (VIQ) of the children with athetotic cerebral palsy were normal, but lower than the average level of normal children(P<0.05). The IQ, VIQ and performance intelligence quotient (PIQ) of the children with spastic cerebral palsy were below the normal (P<0.05), the difference between VIQ and PIQ was significant (P<0.05). For children with spastic cerebral palsy, there was linear correlation between intelligence and the class of GMFCS, and for children with athetotic cerebral palsy there was no linear correlation. Conclusion There were differences of intelligence level and intelligence structure in different types of cerebral palsy, the correlation between intelligence and the class of GMFCS were also different in different types of cerebral palsy.
