Cross-sectional area of the lumbar back muscles as a function of torso flexion

Jorgensen, Michael J.; Marras, William S.; Gupta, Purnendu (Pergamon, 2003-05)

Quantification of the maximum anatomical cross-sectional area of the lumbar back muscles as a function of torso flexion angle and development of prediction equations as a function of torso flexion and anthropometric measures.
Effect of torso flexion on the lumbar torso extensor muscle sagittal plane moment arms

Jorgensen, Michael J.; Marras, William S.; Gupta, Purnendu; Waters, Thomas R. (Elsevier BV, 2003-09)

Accurate anatomical inputs for biomechanical models are necessary for valid estimates of internal loading. The magnitude of the moment arm of the lumbar erector muscle group is known to vary as a function of such variables ...
