Franjoine et al, 2010. Performance on the Pediatric Balance Scale is significantly affected by age and gender. As children age, scores increase with age with the biggest increase between ages six and seven. Scores on the Pediatric Balance Scale are moderately correlated to age (r=0.689) and height (r=0.650) in typically developing children. Females demonstrated significantly higher scores than their male counterparts across all age groups with the greatest differences occurring between two and four years old.
