Compressive forces during forward flexion and lateral moment tasks. Predicted compressive forces are shown for 30 degrees of flexion (A) and for a lateral moment with 5 kg in the right hand (B). For both panels, ribcage-sternal stiffness, the load bearing contribution of the ribcage, was varied from 0 (no loadbearing by the ribs) to 200% of the baseline value. Compressive force on the vertebral body were strongly dependent on the mechanical contributions of the sternum and ribcage at thoracic levels.
