Your Spine Isn’t a Stack of Jenga Blocks – and a 3D Scan Won’t Fix It

I get it.

When your back’s in bits or your neck won’t turn without a wince, you’d try almost anything to feel normal again. You’re tired, you’re sore, and you just want an answer.

So when an ad pops up promising to scan your body in 3D, pinpoint the exact muscle causing your pain and “fix” your posture? Of course, it’s tempting. I’ve been there. Truly. It sounds like science. Like certainty. Like relief.

But here’s the thing. And I say this with care – not criticism: your spine isn’t a wobbly tower waiting to collapse. And a scan, no matter how high-tech it looks, isn’t the magic answer it’s made out to be.

I know that might be frustrating to hear. It would be so much simpler if pain worked like that. But let’s gently unpack why it doesn’t – and what actually helps instead.

You’re Not Broken Because You’re Asymmetrical

Most of these scanner services revolve around one big idea: that pain comes from poor alignment. That something’s “off” – your hips are tilted, your spine’s curved, one shoulder sits higher than the other – and that straightening everything out will make the pain go away.

But human bodies don’t come in straight lines. They’re not shelves or Jenga towers. They’re adaptable, resilient, and built for variation.

Slight curves in your spine? Normal. One side stronger than the other? Also normal. A shoulder that sits a bit higher? Honestly, most people have that – even the ones with zero pain.

Posture has been unfairly blamed for decades. But high-quality research shows that posture and pain don’t have a consistent relationship. People with “perfect” posture still get back pain. People who slouch often don’t.

So if a scan shows you’re not symmetrical – that doesn’t mean you’re broken. It’s just a snapshot of how you’re built, not a diagnosis.

What Scans Can (and Can’t) Tell You

Let’s be fair. These 3D scanners can do a few things: they measure angles between joints, estimate weight distribution and give a static visual of your standing posture.

But that’s it.

They don’t tell you how you move. They can’t measure strength, sleep, stress or how sensitised your nervous system is. And they definitely can’t explain why you’re in pain.

In fact, they often pick up completely normal differences and label them as faults. You walk out with a colour-coded report that looks alarming – even though it’s describing a body that’s working just fine.

It’s not that your body is the problem. It’s the way the information gets framed.

But It Worked for Me...

Here’s something important:
Just because the explanation was off doesn’t mean your experience wasn’t real.

Plenty of people feel better after going through one of these assessments. That’s valid. But the results aren’t always coming from the scan itself, and rarely because your spine was realigned.

There are lots of reasons someone might feel better afterwards:

• Being heard and given a clear plan can be incredibly powerful. Just knowing someone’s taken you seriously and given you a way forward can ease your system and reduce symptoms.

• You might move differently afterwards – with more awareness or care. That change alone can reduce irritation and help you feel safer in movement.

• The exercises you’re given might be exactly what your body needed. Not because they “fixed your posture”, but because movement helps. Strength, mobility and confidence are powerful pain relievers, whatever label they come with.

So yes, the process might help – but not necessarily for the reasons you were told. And that’s important, because when the pain returns (as it often does), you don’t want to end up back in the loop of scanning, fixing and blaming your posture all over again.

Pain Is Messy – and That’s Okay

Pain isn’t a neat problem with a single cause. It’s shaped by how you move, how you rest, how safe your body feels, and how your nervous system responds to threat.

Sometimes pain is about load and capacity. Sometimes it’s about stress or poor sleep. Sometimes it’s about doing too much too soon – or not enough for too long.

You might feel “out of alignment”, but that doesn’t mean something’s physically wrong. Often, that feeling is your nervous system trying to protect you – like a car alarm going off in the wind. It doesn’t mean you’re damaged.

So, What Can You Actually Do?

If you’re in pain and feeling stuck, here’s what’s worth focusing on:

1. Don’t panic about posture.
A bit of asymmetry is normal. Variety, movement and strength are better protectors than chasing the “right” alignment.

2. Be cautious with overpromising tech.
If a clinic leads with their machines instead of their people, that’s a red flag. Good care is about understanding you, not just scanning your body.

3. Find someone who looks at the bigger picture.
The best physios and coaches ask about your life, your habits and your goals – not just your posture. They help you build resilience, not dependency.

4. Already had a scan? No problem.
It’s not wasted. Just know that it’s one piece of the puzzle – not the full story. A good practitioner can help you make sense of it, without selling you a one-size-fits-all plan.

You Deserve More Than a Printout

If you’ve clicked on one of those ads, it’s probably because you’re fed up. Tired of guessing. Tired of wondering if your body’s letting you down.

That’s fair. Completely.

But please hear this: pain doesn’t mean you’re broken. And fixing your posture isn’t the magic key to feeling better.

Most people don’t need a scan to get started. They need someone who listens. Someone who explains. Someone who helps them build strength, bit by bit, without fear.

At Southampton Physio, we see people every week who’ve been through this mill – sold a story about imbalance, misalignment or some hidden flaw only a machine can detect. And they leave with something far more useful: clarity, confidence and a body that actually feels stronger.

So if you’re done with gimmicks and techy promises – trust that instinct. You’re not being negative. You’re being smart.

Let’s stop pretending pain can be scanned away.
