Design outcomes

Primary

Measure	Time frame
All outcomes were assessed in testing sessions conducted before and after the intervention. The following variables were measured and analyzed for changes: Trunk muscle endurance, assessed using a slightly adapted version of the McGill endurance tests for trunk flexors and extensors Postural abnormalities, evaluated through visual and functional assessments based on an examination form previously used by the research group Functional mobility, measured using the Functional Movement Screen (FMS) Back-related knowledge, assessed via a 9-item knowledge test Psychological well-being, measured using a forward- and back-translated version of the English SCS-C questionnaire (assessing self-compassion in children) and the BSCI-Y questionnaire (assessing self-concept in children)	—
