integrated kinetic chain in 2D

Securing central circulation
The geometric analysis of the thorax kinetic chain model in 2D, the sagittal plane, shows a stable gravity line in dorso-vental direction at the level of  the left atrium. An almost pure rotation  takes place in the golden section of a line connecting T1 and T9 offset.  Compare sagittal balance with a tensegrity structure that can be stabilized by proper prestress and balance it self in a self-equilibrium state. The 2D kinetic chain model follows the rules of physics, showing the geodesics between vertices and  moving towards a state equilibrium and minimal-energy. Spinal sagittal balance in harmony keeps the body’s centre of gravity aligned over the hips and pelvis and more importantly it is a key factor for securing  central  blood circulation.
