In CP, which classification system describes a child’s level of gross motor function and guides prognosis and treatment planning?

• A. GAS
• B. HABIT
• C. GMFCS
• D. PEDI-CAT

Answer: (C)

GMFCS describes a child’s level of gross motor function in cerebral palsy and guides prognosis and treatment planning. It’s a standardized five-level system that classifies motor abilities from basic self-movement to independent walking, with age-specific descriptors to improve reliability. Knowing a child’s GMFCS level helps clinicians predict mobility trajectory, set realistic goals, determine what types of assistive devices or mobility supports may be needed, and tailor therapy and environmental adaptations accordingly. For example, someone at a less independent level may focus more on safe transfers and powered mobility, while a higher level often emphasizes refined walking skills and endurance.

GAS is about measuring progress toward individual goals, HABIT is an intensive therapy program, and PEDI-CAT is a broad functional assessment across domains. They measure aspects of function or outcomes but do not classify gross motor function to guide prognosis in CP.
