Classification of motor function and functional performance in children with cerebral palsy

Objective: To classify children cerebral palsy (CP) using classification systems for mobility and manual function, to compare groups of children with CP regarding gross motor function and functional performance outcomes; and to evaluate associations between; between the functional classifications and the scores obtained in the outcomes that were investigated. Methods: Thirty children with CP were classified using the Gross Motor Function Classification System (GMFCS) and the Manual Abilities Classification System (MACS), and were divided into three groups, based on their classification (mild, moderate or severe) in each of those systems. Gross motor function was documented using the Gross Motor Function Measure (GMFM-66) test, while functional abilities and the caregiver's assistance regarding self-care and mobility were documented using the Pediatric Evaluation of Disability Inventory (PEDI). Results: One-way ANOVA showed that the groups were significantly different regarding the GMFM-66 and PEDI results Post-hoc comparison tests (Scheffe) revealed that the children with moderate impairment (GMFCS) had functional abilities and caregiver support that were similar to those of the mildly impaired children. However, the moderate children (MACS) were not different from the severe children Spearman rank correlations showed strong and significant inverse associations between the functional classifications and the results from the PEDI and GMFM-66 tests. Conclusions: The results suggest that the MACS and GMFCS functional classifications are good indicators of the manual function and mobility of children with CP. These classifications may be useful in the processes of evaluation and intervention planning.
