Normative reference values are essential to identify deviation from normal and evaluate response to treatment. As joint range of motion datasets specific to the pediatric population are infrequently reported in the literature, we determined lower limb passive joint range of motion and bone torsion values from 53 typically developing children aged 4-16 years. Our reference values were consistent with previously published norms, although for some measures, large variability in the literature exists. A clear correlation between joint range and age was observed in most measures. Our results highlight the importance of applying age-matched norms when attempting to identify deviation from normal in the growing child.
