Abstract

To determine intrarater and interrater reliability of common measures of lower extremity alignment among children with obesity. Methods: The Craig test for femoral anteversion, tibiofemoral angle, Foot Posture Index-6, and sit-and-reach test were performed on 25 children without obesity and 25 children with obesity. Results: Intrarater reliability of all measures in both groups was high. The Craig test demonstrated greatest variability with slight interrater reliability in children who were nonobese [intraclass correlation coefficient [ICC] (95% confidence interval [CI]), 0.372 (-0.051 to 0.6420)] and moderate reliability in children who were obese [ICC (95% CI), 0.527 (0.242 to 0.717)]. Interrater reliability for the tibiofemoral angle and Foot Posture Index-6 was moderate to substantial and for the sit-and-reach test was substantial (ICC <0.99) and highly correlated. Measurement of lower extremity alignment among children with obesity was more reproducible than among children who were not obese. Conclusions: Measures of lower extremity alignment and general flexibility in children with obesity are both reproducible and reliable.
