The Gross Motor Function Measure (GMFM) is a standardized observational instrument designed to measure change in gross motor function over time in children with cerebral palsy. The GMFM assesses motor function (how much of a task the child can do) rather than the quality of the motor performance (how well the child performs the task). The GMFM-88 is the original version, and tests 88 items. The GMFM-66 is a newer version, which was reduced to 66 items by Rasch Analysis.
