Two posture tests you can do at home

"My posture is terrible, isn't it?" is one of the sentences I hear most often at the clinic in Pasiano di Pordenone, sometimes before I have said a word. The curiosity makes sense: posture is one of the few things about our body we can check in the mirror every morning.

So here are two simple tests you can do right now, in two minutes, with no equipment. Then I'll explain how to read the result, because what you see is not a diagnosis, and a few degrees of asymmetry matter far less than you think.

What a test done at home can tell you

A test at home does one thing: it makes you notice how you hold yourself. It measures nothing, identifies no causes, and doesn't tell you whether you have or will have back pain. It's a snapshot, taken on one particular day, carrying that day's tiredness and stress.

It's still worth doing, because it shifts your attention. After a test like this, many patients realise for the first time that they always carry their bag on the same shoulder, or that they rotate their trunk to the right at the computer.

The wall test, step by step

You need a clear wall, with no protruding skirting board.

1. Rest your back against the wall, heels 5-10 cm from it and feet hip-width apart.
2. Relax your shoulders and look straight ahead, chin parallel to the floor. Don't straighten up to look good: stay the way you usually are.
3. Check which points touch the wall: glutes, shoulder blades and the back of your head should brush against it without you pushing.
4. Slide one hand behind your lower back and one behind your neck. In both cases your flat hand should fit, not your fist.
5. Stay like that for 20-30 seconds and notice where you feel tension.

If the back of your head doesn't reach the wall unless you lift your chin, that's a sign I often see in people who spend hours in front of a screen. If a whole fist fits behind your lower back, the lumbar curve — the natural hollow low in your back — is working harder than it needs to.

The waist triangles, what to look for

The waist triangles are the two empty spaces between your arms and your hips when you stand with your arms along your body: one on each side.

Stand in front of a mirror, arms relaxed, feet hip-width apart. Compare the two spaces: are they the same size? Is one hand closer to your hip than the other? Look at the height of your shoulders too, and the level of the iliac crests, the two bony edges you feel when you rest your hands on your hips.

I find a small difference in practically everyone: we are asymmetrical by build. An asymmetry only starts to interest me when I find it together with a symptom that keeps coming back in the same spot.

How to read the result without worrying

Do both tests again at another time of day, say first thing in the morning and after eight hours of work: very often they change. That tells you the most important thing: posture isn't a fixed structure but a behaviour, and a behaviour can be changed.

At the clinic I have seen perfectly aligned backs that hurt, and bodies full of asymmetries with no pain in twenty years. The test is not a verdict: it's a reminder.

Why movement matters more than posture

The next question is always the same: "And if my posture is fine but it still hurts?" It happens, and it happens often. The factor I see weighing most is not shape, it's the amount of movement: hours spent sitting, few walks, the same three or four gestures repeated all day.

So before chasing the perfect posture, count the minutes you move. Twenty or thirty minutes of walking a day, and a few moments when your body does something different from usual, beat any correction in front of the mirror. I've also written the 3 essential tips for a healthy back.

When to see an osteopath

These two tests help you look at yourself, they don't diagnose: no result, on its own, explains pain. The advice in this article is not a substitute for a professional assessment.

It's worth booking an appointment when pain has lasted more than two weeks, keeps coming back in the same spot despite rest, radiates down a leg or an arm, or comes with tingling and loss of strength. During the first visit we look at posture, mobility and daily habits together, to understand where the problem comes from and build a tailored plan.
