Construct Validity of the Early Clinical Assessment of Balance in Toddlers with Cerebral Palsy: Brief Report.

Purpose: The purpose of this research was to investigate differences in Early Clinical Assessment of Balance (ECAB) scores within children with cerebral palsy (CP) with different Gross Motor Function Classification System (GMFCS) levels and between children with CP and typical development (TD) who are under three years of age. Methods: The ECAB was administered to fifty children (13 with TD, 16 with GMFCS level II, 11 with GMFCS level III, 10 with GMFCS level III). Results: The group of children of TD had significantly higher scores than all groups of children with CP. There were significant differences in ECAB within the groups of children with CP with different GMFCS levels. Conclusion: The results of this study support the construct validity of the ECAB as a measure of postural control in children under three years of age with CP.
