The conversation about posture comes up loads in clinic. Posture is often blamed for different types of pain - back pain, neck pain, shoulder pain, 'trapped nerves'.. etc.
I work in Occupational Health; lots of sedentary workers come in with aches and pains & are under the impression that their posture is to blame... In reality there are lots of different postural types... all of which ARE COMPLETELY NORMAL!
I stole this graphic from Adam Meakins, AKA The Sports Physio. (Find him here)
The point Adam is making is that there is no 'perfect posture' that keeps us free from pain & safe from niggles. There are different types of posture that are all personal to us, each with differing degrees of curvature.
What your body likes most if it's faced with sedentary tasks is regular movement
You could sit in what you think is the anatomically 'perfect' position... shoulders back, lumbar support, head back, chin tucked etc. but if you don't move regularly you might end up getting aches and pains.
As i've mentioned time and time again in my other blogs - what your body doesn't typically like is rapid change. If you rarely sit all day, then start a new desk job, you might get aches. If you're normally glued to a desk then get stuck into some DIY all day you'll probably feel it too. But the misconception that the position you naturally find yourself in predisposes you to pain is very misleading!
Talk about a vicious cycle!
What we seem to know about the spine in particular and aches related to sitting or standing for long periods of time is that your body likes being moved regularly. By moving regularly you promote healthy muscles, joints, discs, nerves and you keep your nervous system happy. More often than not when we're talking about 'posture' we're talking about time rather than position.
A recent study (found here) showed that sitting slouched, or in 'supported slouching' can actually increase the height of your spinal discs, and can improve their hydration! This study was done with people sat in this position!
Quite incredible!
For the record, aches and pains related to sitting or standing can still benefit from treatment! If you're concerned about your posture, you could always get assessed and discuss your case with a professional. If you're a sedentary worker, limit the time you sit in any position, regardless of whether it's bolt-upright or not! And as Mr Meakins mentions earlier:
"Your best posture is your next one."
