Comparison of three-dimensional multi-segmental foot models used in clinical gait laboratories.

Background: Many skin-mounted three-dimensional multi-segmented foot models are currently in use for gait analysis. Evidence regarding the repeatability of models, including between trial and between assessors, is mixed, and there are no between model comparisons of kinematic results.

Research Question: This study explores differences in kinematics and repeatability between five three-dimensional multi-segmented foot models.
