The purpose of this study was to compare the coupling of eversion to tibial internal rotation in runners with (n=19) and without anterior knee pain (n=17). This relationship was captured using both the traditional EV-TIR ratio and continuously using vector coding. Using vector coding, runners experiencing AKP were found to have a significantly different coupling relationship between 40 and 50% of stance. In contrary, as a result of using a singular value to describe this coupling relationship, traditional EV-TIR ratios were not sensitive enough to detect these differences. Future studies evaluating this coupling relationship should consider using continuous techniques or calculating the EV-TIR ratio over smaller periods of stance.Downloads
