Wounds and Injuries | Study of Sand Versus Wood Chip Surfaces on School Playgrounds to Minimize Injury in School Children

Wounds and Injuries research study

What is the primary objective of this study?

This study will compare children's injury rates (arm fracture, head injury and other injuries) when playing on playground equipment on granite sand versus wood fibre playing surfaces. The hypothesis is that injury rates (arm fracture, head injury and other injuries) among school children are equal on granite sand and wood fibre playground surfaces.
