Everyone assumes a posture of some sort, no matter what they may be doing. Many people think of posture as a static, upright - (even uptight!) - position that is meant to infer qualities of strength and control.
"Poor" posture, on the other hand, is meant to indicate weakness, illness, even lack of intelligence!
Thankfully, the ideas around posture have changed significantly since books on the head, and upright spines. With the epidemic of sitting-related musculoskeletal and other medical conditions, the understanding of the effect of load (mainly Gravity, with sitting) has improved.
The emphasis now is less on "stationery and upright", but more varied and regularly changing. The goal is to shift postural load on to multiple structures (as in sitting, then standing) - to spread the work around the body where possible, on to structures that are more suitable to maintain our body position.
Before I advise on postural loads, I complete an assessment of the position most often regarded as the problem - this is usually sitting. Using a camera to capture the position assumed when sitting, I am able to gain an understanding of how your body is loading, and how this may result in your particular symptoms.
As a physiotherapist I am in the position to provide advice, but also direct treatment of many of the symptoms of prolonged sitting, such as neck pain, carpal tunnel syndrome, work-related upper limb disorder, and other repetitive strain disorders. But treating the symptoms is only a small part of the solution - unless you manage the load, you will continue to require some form of treatment to manage the problem. This can be avoided by following the advice regarding exercise and movement, and using better office equipment such as standing desks.
