Sensitivity and specificity of normalized truncated navicular height in assessment of static foot posture in children aged 6-12 years.

Background: Normalized truncated navicular height (NTNH) is a non-invasive, easy to perform, and simple clinical measure of static foot posture. However, its sensitivity and specificity in evaluation of the static foot posture in children have not been investigated yet.

Objective: To investigate the intra-rater reliability, sensitivity, and specificity of NTNH in evaluation of the static foot posture in children using radiographic measure as a gold standard measure.

Validation of normalized truncated navicular height as a clinical assessment measure of static foot posture to determine flatfoot in children and adolescents: A cross sectional study.

Background: Reliability of clinical measures of static foot posture has been widely debated. However, validity of these measures has not been fully established especially in a pediatric population. The purpose of the study was to investigate reliability and validity of normalized truncated navicular height (NTNH) in assessment of static foot posture to determine flatfoot in children and adolescents using radiographic measures as a criterion gold standard measure.
