Performance of school-aged children with cerebral palsy at GMFCS levels I and II on high-level, sports-focussed gross motor assessments.

High-level gross motor assessments were achievable and appropriately challenging for children with CP at GMFCS I-II. Scores discriminated between performance and were associated with mobility level. Concurrent validity was established between gross motor assessment batteries, and locomotor field tests.IMPLICATIONS FOR REHABILITATIONFor children with cerebral palsy at GMFCS I-II, sports-focussed assessments should be used to assess high-level gross motor function.The Gross Motor Function Measure-Challenge and Test of Gross Motor Development demonstrate no ceiling for children with cerebral palsy at GMFCS I-II.Single-item running and jumping field tests provide targeted skill assessment and estimate sports skills for children with cerebral palsy.
