Medial-lateral CoP-rearfoot relation during stance

Objective: The objective of this study is to find out synchronized Center of Pressure (CoP) and Rearfoot Angle (RA) data specifically related to the subject's gender and their left and right walking stance phase. Subjects:15 masculine (21,87 ± 2,83 years) and 15 feminine (21,87 ± 3,29) with no lower limb injuries or injury past history. Methods: The gait cycle stance phase CoP in three different instants of Ground Reaction Force (RsScan pressure plate) and the synchronized RA data have been computed. Each performer replicated 10 trials for each left and right walking stance phase. Inter- and intra-individual data were statistically analyzed. Results: A significant relation was found between CoP and RA (p < 0,05 and p < 0,01), with different behaviors between left and right walking stance phase and gender. Conclusions: Different left and right stance behavior linking CoP, RA and gender should be considered in assessment procedures. Technology associated to the Biomechanics of Human Movement is a contribution for clinicians.
