Which two outcome measures are most appropriate for evaluating function in children with cerebral palsy?

• A. Peabody Developmental Motor Scales; Movement Assessment Battery for Children
• B. GMFM 88 or 66; PEDI
• C. Bayley Scales of Infant Development
• D. PEDI only

Answer: (B)

Focusing on measuring function in children with cerebral palsy means capturing both what they can do with their bodies and how that translates into everyday activities. The Gross Motor Function Measure (GMFM) is specifically designed to quantify gross motor abilities in CP, tracking progress across key task families like lying and rolling, sitting, crawling, standing, and walking, running, and jumping. The version with 88 items or the streamlined 66-item version both provide a sensitive readout of changes in motor function over time, whether due to therapy, therapy intensity, or growth. Pairing that with the Pediatric Evaluation of Disability Inventory (PEDI) gives a complementary view of daily life. PEDI looks at what the child can do in real-world activities across self-care, mobility, and social function, including how much help is needed and how independently they perform tasks. This reflects the child’s participation and independence in everyday environments, which is exactly what clinicians want to influence with intervention. Together, these two measures cover both the motor impairment level and the practical functional impact, making them the best pair for evaluating function in children with CP. Other measures mentioned are less ideal for this purpose on their own. Developmental motor scales like the Bayley or PDMS-2 assess general motor development and may be appropriate for younger or non-CP populations, but they’re not as CP-specific or as sensitive to function changes over time in older children. The Movement Assessment Battery for Children focuses on motor coordination rather than CP-specific functional outcomes, and using only the PEDI would miss objective tracking of changes in gross motor abilities.
