Background and Purpose. Evaluating foot biomechanics is an essential part of effective treatment of patients with a variety of injuries ranging from low back pain to plantar fasciitis. Many clinicians continue to use static foot assessments to evaluate injuries that result from dynamic foot motion during gait, despite the lack of research supporting the validity of such static measures. The purpose of this study was to examine the correlation between four static foot measurements and dynamic rearfoot motion during walking and running.

Methods. The right feet of thirty-three subjects were assessed for navicular drop, navicular drift, arch angle, and calcaneal angle while standing on both legs with their right feet positioned in subtalar neutral. These static measures were performed again while each subject maintained one-legged standing on the right leg with their right foot relaxed. Peak calcaneal eversion was measured while subjects walked and ran using the two-dimensional Peak Motion Analysis System.

Results. The coefficients of determination between all four static measures and peak calcaneal eversion angle during walking and running were poor (~

Conclusion and Discussion. Static foot assessment may not be a valid method of determining peak calcaneal angle during gait. A valid, reliable dynamic assessment method needs to be developed to use clinically to assess dynamic foot biomechanics.
