 The Activities Scale for Kids performance ASKp is one of the few self-assessment questionnaires in pediatric rehabilitation that measures child perception in performance of daily routine activities. ASKp is composed of 30 questions designed to explore activities and participation in children and teenagers with musculoskeletal disorders. Scores assess level of physical ability, identify appropriate treatment and monitor changes over time. We recently undertook the cross-cultural validation to achieve a culturally adapted Italian version of ASKp: the Italian version is now to be tested on Italian children.
