Reliability and validity of a computer game-based tool of upper extremity assessment for object manipulation tasks in children with cerebral palsy.

Introduction: A computer game-based upper extremity (CUE) assessment tool is developed to quantify manual dexterity of children with Cerebral Palsy (CP). The purpose of this study was to determine test-retest reliability of the CUE performance measures (success rate, movement onset time, movement error, and movement variation) and convergent validity with the Peabody Developmental Motor Scale version 2 (PDMS-2) and the Quality of Upper Extremity Skills Test (QUEST).

Methods: Thirty-five children with CP aged four to ten years were tested on two occasions two weeks apart.
