To stand requires significant forces.

POSTURE EQUILIBRIUM ISSUE (or before even to walk it is required to stand) A 1m 70 person fit with a 6 1/2 gets a bipodal support of approximately 190cm², it is to say a square of about 14cm x 14cm, therefore a ratio between height and perimeter of 3. Let us imagine a building of 4 stores of 12 m high, with the main weight located at the top, that would stand without foundations on a surface which perimeter is 4 m, i.e. a 1m x 1 m square !!!. To make it stand would require huge shrouds fixed in the ground. Thus we are standing, we are moving without showing major efforts, while handling continuously and automatically huge forces to stay balanced. How is that possible ? Looking back to the imagined building, it can be standing thanks to its shrouds. Following this rationale, we also need to have shrouds with the difference that we have the shrouds in our own body. | ||||

The shrouds for the human are his tonic muscles. |
THE SHROUD MECHANISMS The shrouds are defined as flexible and resistant links used to maintain a solid structure in equilibrium. Our solid structure is our skeleton, built of bone pieces, that can only stand in space thanks to the shrouds that are our muscles. Two types of muscular fibers exist :
The set of the tonic muscles (shrouds) that make us stand in space and of the sub-conscious neurological system that controls them is called the Posture Tonic System (PTS). The PTS continuously controls the Static, prepares the motion, prompts it, enforces it, provides its counter support and stops it. | ||||

The foot plays a central role in the posture control mechanism. |
FOOT MAIN ROLE The shoulder and hip deviations lead to mechanical constraints from top to bottom. The foot first adapts itself with deformation, then becomes fixed within a few months and generates its own constraints. This becomes a self sustained process of posture desiquilibrium. The ground is a posture invariant, that is to say that, whatever the ground, the foot must adapt to make us stand. With its receptors, the foot informs via the sensitive channels the sub-cortical centers that answer by posture adaptation through the extra-pyramidal motion channels. The foot therefore balances all abnormal disequilibria's coming from top and the information coming from the ground. The joint constraints are then multiplied.
