This project (CO-OP II) is the second in a series of three studies to validate a new treatment approach for children with cerebral palsy (CP). The initial study was comprised of a series of four single case studies with children with CP. It evaluated the potential of the Cognitive Orientation to Occupational Performance (CO-OP) approach to be used with children with CP and tested the procedures for CO-OP II. The overall objective of the full series of studies is to determine whether better functional outcomes are achieved for children with CP with CO-OP intervention than with contemporary occupational therapy treatment.
