The purpose of this study was to determine the effectiveness of two types of in-shoe custom made orthotics in altering the motion of the foot and muscle activity of select muscles of the lower leg in individuals experiencing lower extremity symptoms of a non traumatic origin. We hypothesized that orthotics would decrease the extent of motion of the during walking and running when compared to a barefoot condition. The investigators further hypothesized that orthotics would decrease the amount of muscle activity seen during walking and running when compared to barefoot walking.
