DOES REARFOOT EVERSION ANGLE REPRESENT REARFOOT EXTERNAL EVERSION MOMENT DURING STANCE PHASE OF RUNNING?

Abstract

Rearfoot external eversion moment has been thought to contribute to overuse running injuries. Conventionally, the rearfoot eversion angle was used to evaluate the susceptibility of overuse running injuries. However, the relationship between the angle and moment has never been examined. Therefore, in this study, the relationship between the maximum rearfoot eversion angle and the maximum rearfoot external eversion moment during stance phase of running were estimated. As poor, not significant correlation obtained between these two variables, it can be assumed that the rearfoot eversion angle does not represent external eversion moment. From this result, it can be suggested that the use the kinetic variables such as external moment, is preferred to detect the susceptibility of overuse running injuries.
