Sitting in a reclining position with a slightly rounded back most noticeably reduces loading in the spinal column!

Who did the research: Independent Lecturer Dr.H-J.Wilke, University of Ulm

The aim: To determine the pressure in the intervertebral disc in different postures by the simulation of a very wide variety of people’s working activities.

The trial: A measurement probe was inserted into the intervertebral disc of a living human being. The subject carried out different exercises and took up different sitting positions, and at each of these the pressure in the intervertebral disc was measured.

The result: When sitting in the hollow back posture the pressure in the intervertebral disc is higher than when seated in a reclining position in a convex back posture.

From this it follows that: Sitting comfortably in a reclining position with a slightly rounded back most noticeably reduces loading in the spinal column.
