Ontario Motor Growth Study

The Ontario Motor Growth Study was a longitudinal study designed to chart the gross motor progress of a randomly selected sample of over 650 Ontario children with cerebral palsy. From this study we created five Motor Growth Curves to describe the patterns of motor development of children with varying "severities" of cerebral palsy using the five levels of the Gross Motor Function Classification System (GMFCS). The Motor Growth Curves are similar to the growth charts that are used to follow the height and weight of children as they grow.
