Purpose: This project aimed to determine if change occurs over time for impairments of balance, range of motion (ROM), endurance, and strength of children with cerebral palsy (CP), by Gross Motor Function Classification System (GMFCS) levels.

Methods: Measurements were completed in 77 children at two sessions (T1, T2) on average 5.8 years apart. Mean ages were 2.9 years (SD .9) and 8.7 years (SD 1.1) at T1 and T2, respectively.

Results: Significant differences were noted from T1 to T2 for some children (GMFCS levels I, II, and III/IV: balance increased, GMFCS levels I and II: strength increased, and GMFCS levels III/IV and V: ROM decreased). Endurance scores were not different. Endurance scores did not change.

Conclusions: Longitudinal changes in most impairments occurred in children with CP. Monitoring and targeted interventions should support each child’s development.
