Traditional methods used to assess foot posture during dynamic activities rely on static measures of foot dimensions during partial weight bearing. In recent years, evidence was found which links musculoskeletal and overuse injury patterns in athletes to foot posture. To be able to accurately assess the relationship between injury patterns and foot posture, it might be necessary to study changes in the foot posture during the dynamic activities that the athlete normally undertakes. The purpose of this research is to introduce a method which can be used to measure changes in the foot posture during dynamic activities, hence providing a better prediction of the changes in the foot posture and its relationship to lower limb injuries. The results from static and dynamic Foot posture measures were compared for two subjects and the results showed significant differences.
