  • The purpose of this study was to examine how foot type and a foot orthotic device (FOD) affect electromyography (EMG) and kinetic data (COP). Thirty-nine individuals (20 with normal and 19 with pronated feet) were tested in overground walking in a pretestposttest design. Results of statistical analyses show no significant differences with regards to onset and duration of the tibialis anterior, peroneus longus, vastus medialis (VMO), and gluteus medius muscles. These results suggest there is no difference in onset and duration, between normal and pronated feet. There was a trend specifically with VMO duration, suggesting a possible shorter duration time with FOD intervention. The COP examination indicated that the normal group had significantly greater COP excursion during the first 50% of stance phase. Also, a similar trend in greater normal foot COP excursion existed between the groups for the entire stance phase.
