Why math does not close in standard practices (PT / DMI as commonly applied) and why it does close in Movement Lesson as you practice it.

What “math works out” actually means here

When you say the math works, you are not talking about equations on paper.
You’re talking about conservation and transfer:

• force → movement

• movement → organization

• organization → reduced energy cost

• reduced energy cost → repeatability

• repeatability → development

If any step breaks, the system compensates, and the math diverges. That’s the lens. 

Standard PT / DMI: What variables do they prioritize?

Most conventional approaches optimize for local variables:

• muscle activation

• joint range of motion

• Symmetry in static positions

• linear strength

• task completion (“walking”, “standing”, “grasping”)

These variables are treated as independent.  The implicit math assumption They assume: If we improve local variables, a global organization will emerge. That as...

Vision has three major load-handling stages:

• Input – eyes, retina, optic nerve

• Routing & prediction – brainstem, thalamus, visual midline integration

• Interpretation – cortical visual areas (ventral + dorsal streams)

In Cortical Visual Impairment (CVI):

• input may be adequate

• interpretation may exist

• But routing + load regulation is unreliable

 What if you realize that we are functioning around gravity, yet this is a containment.

One of the most important things that happens to us during the birthing process is exposure to gravity.

 To become a constant, we need to add intake and elimination. Once gravity exists as a constant, the question becomes:

How do I move, adapt, and function without fighting the container? The answer is rotation.

Rotation allows:

• load redistribution without collapse

• transition without force escalation

• movement without loss of reference

• waste venting without explosion

Rotation is cooperation with gravity, not resistance to it.

That’s why:

• joints rotate

• spines spiral

• gait alternates

• midline organizes around torsion

• balance emerges from twist, not rigidity

A non-rotational system inside gravity must:

• push

• brace

• lock

• flail

Which is exactly what you see in robots — and dysregulated humans.

This is a real structural blind spot that causes a lot of misunderstanding and delays in providing help.

People assume:

• walking = system is fine

• Speech = separate "language problem."

But mechanically, that's wrong. Structurally, walking and talking are not parallel skills. They draw on different load-variance budgets. Walking can emerge with compensation.

A child can walk if they can:

• lock joints

• stiffen the trunk

• offload variance into hips, knees, feet

• reduce degrees of freedom

That's a brute-force solution to gravity. It works, but it's expensive. Speech cannot tolerate that compensation.

Speech requires:

• fine breath modulation

• rapid pressure changes

• stable midline without bracing

• dissociation of jaw, tongue, larynx from trunk load

If the system is using:

• breath to stabilize posture

• trunk stiffness to manage gravity

• jaw/neck as auxiliary stabilizers

Then speech becomes mechanically unsafe. So the system...

1- There is no crawl - This is not a typical type of crawling. Although it is a form of locomotion, it's about your child pushing its body off the floor.

2- Vision - Your child cannot set up their vision to see through a four-point crawl.

3- Missed Milestones - Your child cannot come into sitting, then go into all-fours. Managing transition skills continues to be a struggle.

4- Midline - A forced midline is much harder to work around and can stop or limit a child's crossing midline.
