Tests See a Still Frame; Symptoms Appear While Moving

Tests See a Still Frame; Symptoms Appear While Moving

They say the images are clean. X-ray, and MRI if needed, and neither bone nor joint shows anything wrong. Yet the place is still tight, it catches on certain movements, and strength does not come through properly. Breathing is the same. The chest film is normal, oxygen readings are normal, and the breath is shallow and stifled.

At such times many people ask the same question. "They say the structure is fine — so why am I like this?"

What a Test Sees Well Is Shape

Many tests look mainly at shape, and they look very accurately. Is what should be there in its place? Has something appeared that should not be? Are size and form within the normal range? For measuring these there is nothing better. Whether a bone is broken, whether a mass has formed, whether a vessel is blocked — these "abnormalities of shape" are what a test finds first and most accurately.

But a good deal of bodily discomfort is not a matter of shape. The parts are fine; how those parts move has gone off.

The same joint moving smoothly, in the right direction, at the right time is not the same as a joint of identical shape moving stiffly and catching. The same lungs filling and emptying deeply and evenly are not the same as lungs heaving shallowly and fast. A single image captures shape but misses movement. Movement happens within time, so stopping it in one frame makes it disappear.

Movement Has Three Faces

I divide that "movement" into three.

One is pressure. Inside the body, pressure is always rising somewhere and falling somewhere else. With every breath the pressure in the chest and the abdomen alternates, and on that wave blood returns and lymph flows. If pressure cannot rise and fall properly, then even with every part intact the body feels it is "not circulating well."

Two is elasticity. Tissue gives when pressed and comes back when released. That force returning from a stretch is elasticity. When elasticity dulls, the same pressing does not spring back as well, and recovery is slower.

Three is rhythm. Most of the body's work happens on time. Night and day, in-breath and out-breath, tightening and releasing. When that rhythm goes off, each part can be doing its job and the whole still stumbles.

Pressure, elasticity, rhythm. All three are "movement," and standard tests mostly do not measure them.

The Test Is Not Wrong

I would not want this misunderstood. I am not saying tests are inadequate. There are tests that measure function, that watch over time, that capture movement as it happens. It is only that the tests we commonly take in a single sitting are close to a still frame. And screening out abnormalities of shape is essential, and that is what tests do best, because serious disease usually shows itself first in shape.

But when a test says "nothing abnormal," the precise meaning is "there is no abnormality of shape of the kind it is built to find." That is not the same sentence as "nothing is going on." Shape can be normal while movement has gone off, and the body reports that to us as discomfort.

So when I see someone like this, before searching again for what has broken, I look first at how it moves. Whether pressure rises and falls properly, whether a pressed place comes back, whether the rhythm holds. The stories that follow are each a look at one aspect of that movement.

Discomfort that remains while shape is normal is usually not a signal of breakdown but a report on movement. What follows is the work of opening that report one page at a time.
