【Objective】 To evaluate the burden of comorbidities in a sample of children with spastic cerebral palsy and stratified according to both neurologic subtype and functional capability with respect to gross motor skills. 【Methods】 Scpchild registry and systematic management database was utilized to identify children over 4-year-old with Spastic cerebral palsy from Feb 2008 to Sep 2010. 172 children (male 109 ,female 63) were involved. The average age was 8.0 years old. Information on neurologic subtype classified according to the qualitative nature and topographic distribution of the motor impairment on neurologic examination, Gross Motor Function Classification System (GMFCS) categorization of motor skills, and the presence of certain comorbidities(epilepsy, visual impairment, hearing impairment and speech disorder) was obtained. 【Results】 The incidence of epilepsy was higher in children with hemiplegia or quadriplegia than those with diplegia. The incidence of visual impairment was higher in children with diplegia and quadriplegia than those with hemiplegia. The incidence of single speech disorder or multiple comorbidities was higher in children with quadriplegia. The frequency of multiple comorbidities was higher in children at GMFCS level IV～V than those at level I~III. 【Conclusions】 The frequency of comorbidities in children with spastic cerebral palsy is correlated with the neurologic subtype and the gross motor function level. The incidence of multiple comorbidities is higher in children with more severe functional impairment.
