Mean values of estimated (a) muscle ACSAs, (b) moment arm in the medial-lateral direction (MA-X), and (c) moment arm in the anterior-posterior direction (MA-Y), for vertebral levels T6 through L5. Note that for MA-Y, positive indicates anterior to, and negative indicates posterior to, the center of the vertebral body. Values for shaded levels (T6, T12, L1) were estimated by interpolation or extrapolation.
