Do you think it's movement that creates posture?

What if it all started… with a micro-adjustment even before you moved?

Before running, you straighten up.
Before jumping, you position yourself.
Before raising an arm, you stabilize your trunk.

But all of this… you don’t decide.
It’s your brain that anticipates. Your nervous system that adjusts.
And this happens even before the movement.

This is what we call anticipated postural adjustments.

Posture is not a consequence of movement

It is its condition of emergence.

Imagine an archetype: a "perfect" squat.
Everyone looks at it from bottom to top:

• 👉 ankles,
• 👉 knees,
• 👉 hips,
• 👉 trunk…

But the question we never ask is:

"What did the brain do BEFORE the person descended?"

The perception-action loop

Because yes: even before the movement begins, the perception-action or sensorimotor loop has been activated.

The brain has taken into account:

• the plantar pressure,
• the visual horizon,
• the vestibular verticality,
• the tension in the fascia…
• …and it adjusted the posture in a flash, to allow the action.

It’s invisible. And yet, that’s where everything plays out.

An imbalance in these micro-adjustments, and your movement becomes costly, compensated, unstable.

But since it’s preconscious, no one sees it.
Unless you know how to test the sensorimotor loop.
Unless you know how to detect the flaw upstream.

What we teach at LabO-RNP

This is exactly what we teach: observe, test, calibrate upstream of the movement.

Our latest podcast talks about a myth that’s hard to shake off:

“Unstable surfaces work balance.”

Spoiler: no. Not without testing. Not without a loop.
