For decades, poor posture was treated as a primary cause of back and neck pain. More recently the pendulum has swung hard the other way, with "posture doesn't matter" becoming a common refrain.
Both positions overshoot. Here's a more accurate picture.
What the evidence actually suggests
Studies have repeatedly failed to find a strong, consistent link between static posture — how you stand or sit in a still photograph — and whether someone has pain. Plenty of people with textbook-poor posture have none, and plenty with excellent posture have plenty.
So the old model, where a specific spinal alignment reliably predicts pain, doesn't hold up.
What still matters
That's a different claim from "posture is irrelevant." What the evidence does support:
- Sustained positions matter more than shape. Holding any posture for hours loads the same tissues continuously. The problem is the duration, not the geometry.
- Movement variability matters. The best posture is genuinely the next one — regular position changes reduce cumulative tissue load.
- Position matters under load. Spinal position during heavy lifting is a different question entirely, and there it does matter.
- Extremes can be relevant. Significant postural adaptations, particularly with associated weakness or restriction, can contribute to symptoms.
- Comfort counts. If a position is uncomfortable for you, that's reason enough to change it.
A more useful way to think about it
Rather than asking "is my posture correct?", ask:
- How long am I holding this position without changing?
- Do I have the strength and mobility to access other positions comfortably?
- Does this position reproduce my symptoms?
- Can I move well when I need to?
What this means practically
We don't try to reshape people into an idealized alignment. We do address restrictions that limit your options, build capacity so sustained positions are better tolerated, and encourage movement variety through the day.
If you work at a desk, the highest-value change is usually not a new chair or a rigid posture rule — it's getting up and moving more often. More on this in chiropractic for desk workers.
And if a particular position consistently reproduces your pain, that's worth assessing — not because the posture is inherently wrong, but because it's telling you something specific about your tissue tolerance.
