There remains significant debate and controversy about the position of the true axis of this rotation, the extent of rotation (which may be as little as 0.5 degrees on a recent study), and the amount of translational movement in other planes. Full lumbar flexion changes the line of action of these muscle compromising their role to support anterior shear forces on ... move so little (Vleeming et al.,) that it shouldn’t matter significantly.
