Potential predictors of changes in gross motor function during various tasks for children with cerebral palsy: A follow-up study

► Predictors of various motor outcome changes in cerebral palsy (CP) were identified. ► Knee extensor strength is a robust predictor for changes in gross motor outcomes. ► Abdominal muscle strength predicted changes in the running speed and agility. ► Knee muscle strength is a potential biomarker for predicting gross motor changes.
