The pelvis: "Strange attractor" of the postural system. A study based on a group of 332 children between 2 and 12 years old

Objectives The aim of this work is to show that the pelvis represents the focal point of the postural system, or rather, the link between muscular and skeletal systems. The pelvis is the seat of insertion of lower extremity and trunk musculature, and these muscles are controlled by the postural system. The afferent postural information relayed by this musculature conditions the spatial order of the musculoskeletal system, so that correct afferent conditioning leads to proper musculoskeletal orientation aligned with the center of gravity.
