What is GMFM-66 and what does it measure?

• A. GMFM-66 measures intelligence.
• B. GMFM-66 is a Rasch-calibrated version of the GMFM-88 with 66 items and measures five dimensions of gross motor function in children with CP.
• C. GMFM-66 is a scale for bone density.
• D. GMFM-66 is a pediatric pain scale.

Answer: (B)

GMFM-66 is a Rasch-calibrated version of the GMFM-88 that includes 66 items and provides a measure of gross motor function across five domains in children with cerebral palsy. The five domains cover lying and rolling, sitting, crawling and kneeling, standing, and walking, running, and jumping. The Rasch calibration converts the raw item scores into an interval-scale score, making it more sensitive to small changes and suitable for tracking progress over time or in response to therapy. It does not assess intelligence, bone density, or pain.
