Postural plumb system allows human being stability relative to outside world.

This system operates in a loop to continuously ensure an adapted (muscular) response to stimulations in strategic locations (foot, eye, inner ear).

The sensitivity thresholds to body oscillations vary according to the sensors.

For example, feet have skin receptors that are sensitive to small pressure variations of 300 mg and can perceive relief differences of only 5 microns. They are the first to be activated during slight oscillations. The eyes then complement the information, while the inner ear remains insensitive to oscillations when the subject is standing. The performance of this system keeps the center of gravity on the ground (Center of Podal Pressure) within an area of less than 1 cm², thus saving muscular energy used to maintain a prolonged posture.

Any dysfunction of this system can lead to tension areas within tissues (muscles, fascia, joints,...).

Postural reprogramming is possible by manipulating the sensory receptors of the plantar sole (with posturopodial insoles) or by acting on the eyes (with postural prisms). The examination is carried out by a recognized posturopodist posturologist of the International Posturology Association following seven years of continuous training at the Institute of Posturology in Paris.

In practice, the type of insoles will be chosen after a thorough examination of about an hour (interrogation, palpation, clinical test, test of insole elements...) at the end of which the therapeutic strategy is established. The insoles are worn for a month until the second consultation, necessary to check, improve, or evolve the insoles according to the body's reaction to the stimulations. An annual visit is recommended to check if the insoles are still suitable.
