Reliability of normalised truncated navicular height in assessment of static foot posture in children (6–12 years)

Abstract

Objective: To investigate the reliability of normalised truncated navicular height (NTNH) as a clinical measure of static foot posture in children.

Methods: A cross-sectional study of a random sample of 300 school-aged children 6–12 years with mean ± SD of (9.44 ± 1.76) years. Two raters independently recoded the NTNH for each participant. Intrarater and interrater reliability of NTNH was assessed using intraclass correlation coefficient (ICC).

Results: NTNH demonstrated excellent intrarater reliability (ICC = 0.98–0.99) and interrater reliability (ICC = 0.98).

Conclusion: NTNH is a simple, quick and reliable clinical measure for static foot posture in the paediatric population.
