Background: A study was undertaken to investigate the ability to predict dynamic foot posture from static measurements.

Methods: Arch height and arch height ratio measurements were obtained from videotape images of the medial aspect of the foot during standing, walking, and jogging in 5 male and 13 female asymptomatic subjects.

Results: Arch height and arch height ratio measurements taken in standing explained 66% to 83% of the variance associated with these measurements at midstance during walking and running. Arch height and arch height ratio demonstrated high reliability as static and dynamic measures.

Conclusions: The results of this study support the use of arch height and arch height ratio measurements taken statically in the clinical assessment of the foot and may assist the clinician in estimating foot posture during dynamic activity in patients with lower-limb injuries.
