Change in load on L3 disc



Within the lumbar spine, different postures can increase the pressure on the intervertebral discs. Studies of intervertebral pressure changes in the L3 disc with changes in posture were performed and concluded in a table similar to the above one. The pressure in the standing posture is classified as the norm, and the values given are increases or decreases above or below this norm that occur with the change in posture (Magee DJ. Orthopedic physical assessment, 5th ed. Alberta: Saunders Elsevier; 2007).
