 All of us are constantly dealing with gravity. But there are two different ways the body can organize itself with it. 

1. Functional gravity organization. The body organizes with gravity.

That means:

• the pelvis tilts slightly forward

• the spine lengthens upward

• the head balances over the body

• movement flows forward and outward

This makes things like eating, reaching, swallowing, and speaking much easier, because the body is cooperating with gravity.

2. Compressive or defensive gravity organization

Some children develop a pattern where their bodies try to protect themselves from gravity instead of organizing with it.

When that happens, the body often:

• leans backward

• stiffens the trunk

• pulls the head away from activity

• tightens the jaw or throat

This can happen for many reasons, including:

• medical experiences

• tubes or procedures

• muscle tone differences

• neurological development

The nervous system is simply tryin...

Most humans naturally move toward food, not away from it.

When we eat, our body usually does a small sequence:

 Pelvis tilts slightly forward
 Pubic bone moves toward the table
 The trunk lengthens and stabilizes
 The head and jaw move forward to meet the food

This forward organization helps with:

• swallowing

• tongue movement

• jaw control

• managing the food bolus

Gravity actually assists swallowing when we are slightly forward.

It's like the body being on a small swing. The pelvis organizes first, then the upper body follows.

Why tube-fed or medically complex children often lean back:

Children who have had G-tubes or NG tubes sometimes develop the opposite pattern.

Their nervous system may associate the mouth or throat with:

• discomfort

• gagging

• tubes

• medical procedures

So instead of leaning toward the stimulus, the body protects itself by leaning away.

This creates a posture like:

• pelvis tucked under

• trunk leaning back

For a long time, people said the Honey bee “shouldn’t be able to fly” because early aerodynamic models treated wings like airplane wings. By those simple equations, bees seemed too heavy for their wing size.

But the mistake was assuming fixed-wing aerodynamics.

Bees don’t fly like airplanes.

They fly using unsteady aerodynamics, which includes:

• rapid wing rotation

• vortices (small spinning air currents)

• figure-eight wing strokes

The rotational mechanics bees use

A bee’s wings beat around 200–230 times per second.

Each stroke creates:

• A downward push of air

• A rotational flip of the wing

• A swirling vortex above the wing

Those vortices temporarily lower the pressure above the wing, thereby increasing the amount of lift from the steady airflow, as in an airplane.

It comes from continuous rotational air disturbances.

Why rotation matters

When the wing flips at the top of each stroke, it creates what scientists call a leading-edge vortex.

That vor...

Touch is not manipulation. Touch is a way to reveal how the body is organizing under gravity.

When touch is applied correctly, the body will show:

• where load is held

• where rotation is available

• where rotation is resisted

• how the nervous system organizes response

So touch becomes an observational tool, not a corrective one.

 Touch Reveals Load Distribution

Observe how a light touch changes:

• weight transfer

• rotation through the pelvis

• rib cage response

• foot grounding

“What does the body do when it senses touch under gravity?”

 Touch and Rotational Response

Use touch to see how the body organizes rotation through the midline.

Examples to observe:

• Does the rib cage rotate or stiffen?

• Does the pelvis respond first?

• Does the body rotate as a unit or in segments?

This reveals movement organization patterns.

 Touch and Sensory Awareness

When people suddenly feel touch, they often become more aware of the movem...

Science of Structural Movement

Research the Movement LessonTM system

Presented at the Movement, Brain & Cognition Conference

Oxford University — 2017

Human movement does not arise randomly. It is developed through structural principles that begin in childhood and later influence coordination, spatial cognition, and physical performance.

Gravity is the first stimulus for the development of human movement.

At the beginning of life, the human being does not move intentionally; he must first learn to organize his body within the force of gravity. As the nervous system develops, the body learns to interact with this force through rotation, weight transfer, and midline integration.

Key Structural Principles:

Gravity

Gravity is the fundamental external force that shapes posture and movement. The human body must first organize its relationship with gravity before it can develop balance, stability, and locomotion.

Rotation

Rotation is the main mechanism by which the body org...
