Improving participation of children with cerebral palsy is an important outcome in the practice of pediatric rehabilitation. Current knowledge of how a child's interactions with various environments influence participation can affect care provision to children with cerebral palsy. The literature was searched using electronic databases and reference lists from 1991 to 2008. Studies included reports on one or more factors influencing a child's participation. Using the International Classification of Function, Disability, and Health (ICF) as a framework, factors that influence participation are summarized.
