Muscle Weakness and Pain May Share the Same Wiring — What Muscle IQ in Orem Tests For

You have been told to strengthen it. You have been told the pain will settle down. Nobody explained why the two never quite line up.

A 2019 study by Granovsky and colleagues, published in the journal Pain Reports, suggests they may sit closer together than anyone assumed — close enough that the signal your brain sends to your muscles and your body's own ability to quiet pain appear to travel on shared wiring.

Two Measurements That Turned Out to Match

Researchers tested 41 healthy young adults on two things that, until then, belonged to two different fields of study.

The first was how strongly the brain drives muscle. They used a painless magnetic pulse over the movement part of the brain to see how strong a signal was actually reaching the muscle, and how long it lasted.

The second was how well the body turns its own pain down. There is a well-documented effect in which one uncomfortable input causes pain elsewhere in the body to get quieter. How much quieter it gets is a rough score for how well that system is running.

The two scores tracked each other. People with a bigger signal at the muscle also tended to be better at turning their own pain down, and both features of that signal — its size and its duration — followed the pattern independently.

One detail is worth pausing on. These were healthy young adults. No injury, no long-standing condition. The connection was already there before anything had gone wrong.

Why That Matters When Something Hurts

Your nervous system decides how much drive your muscles get. It helps to picture a dial. When tissue is irritated, that irritation keeps sending signals up to the brain, and one common result is that the dial gets turned down on nearby muscles. Nothing tore. The muscle simply stops getting the full signal — it goes partly offline.

Then the neighbors take over. Muscles that were never meant to carry that load work harder, thicken, and start complaining themselves. That is often why the ache moves, or why it keeps returning to a spot the scan called normal.

Now add what these researchers found. If the drive to your muscles and the quieting of your pain run on overlapping circuitry, then a muscle testing weak may not be only a muscle finding. It may also say something about the state of the system that is supposed to be turning your pain down — which is one reason an evaluation at Muscle IQ Physical Therapy often begins with muscles that do not hurt.

What a Muscle IQ Evaluation Looks Like in Orem

The practical version is simple, and you can often watch it happen inside a single visit.

1. Muscles get tested — including ones you never mentioned.

2. Hands-on treatment is aimed at the tissue that appears to be driving the muscle inhibition.

3. Those same muscles get tested again.

When a muscle that gave way holds a few minutes later, no tissue rebuilt itself in the meantime. The signal changed. That is information — it points toward where the irritation actually lives, which is not always where it hurts. Not everyone shows that change on the first visit, and one test is never the whole picture.

Once the signal is back, strengthening has somewhere to go. That is where equipment like the computerized DAVID machines earns its place — after the reason for the weakness has been found, not instead of finding it.

For patients across Orem, Provo, Lindon, and the rest of Utah County, this is why a first visit here runs long and unhurried. Finding the tissue that is driving the problem takes a full evaluation, not a quick look at the sore spot.

Muscle IQ works with many major plans, including DMBA, BlueCross BlueShield, TRICARE, EMI Health, and Allstate, and your specific benefits can be verified before your first visit.

The Honest Limits

This was 41 healthy young adults, and it measured a relationship — not a cause. It was not done in people living with long-standing pain, and it does not show that raising one score raises the other.

What it does do is put evidence under something clinicians have watched for years: the muscle system and the pain-control system are not strangers to each other. And it is worth saying plainly — imaging that reads normal does not rule out a signal problem.

Weakness and pain often travel together. The useful question is what is turning the signal down, and that is a question worth asking out loud.
