Fig. 1 A top-down schematic view of the feet placement with respect to the forceplate location during the 5 tasks. The shaded foot represents the direction of maximal weight shifting during the unilateral tasks of lateral, forward, and backward weight shifting. For the bilateral tasks, quiet standing and rising from a chair, both feet are shaded gray because the task requires the individual to bear weight through both feet as equally as possible. The following figures depict the task and corresponding foot orientation: (A) quiet standing, (B) rising from a chair (4 legs of the chair are represented as black circles with subject's feet on F2 and F3), (C) lateral weight shift to the left foot, (D) lateral weight shift to the right foot, (E) forward weight shift to the right foot, (F) backward weight shift to the left foot, (G) forward weight shift to the left foot, and (H) backward weight shift to the right foot.
