Purpose: The purpose of this study is to determine if subtalar joint position affects the activity of hip musculature in static standing, and by those results imply a correlation between foot position and ACL injury risk.
Methods: Thirty participants took part in this randomized study in which EMG data were collected during 3 trials of 3 subtalar joint positions on the right lower extremity. Subtalar joint positions included a flat surface to represent a neutral subtalar position, a 5-degree incline rising from lateral to medial, promoting a supinated attitude of the foot, and the third position was on a 5- …
