Objective: The purpose of this study was to determine the influence of rearfoot posture on dynamic frontal plane rearfoot motion during the stance phase of walking. Methods: The rearfoot angle (RFA) was measured in 164 feet and then two groups were created representing extreme values. The two groups were labeled as either EVERTED or INVERTED. Frontal plane rearfoot kinematics was then assessed using an electromagnetic motion analysis system as subjects walked barefoot. Results: The results of this study indicated that there is no significant (P>0.05) difference between either of the experimental groups with regard to frontal plane rearfoot motion. These results indicate that static rearfoot angle does not influence dynamic rearfoot motion. Conclusion: It also raises serious questions concerning the clinical utility of measuring the rearfoot angle since it does not appear to be a good predictor of a person's rearfoot motion pattern during walking.
