Postural and Movement Disorders

Reviews of the research have found the relationship between measured posture — forward head position, thoracic curvature, pelvic tilt — and pain to be inconsistent, and have not established that posture causes pain 12. People with markedly asymmetrical posture are frequently pain-free.

This matters because posture-focused advice can make people fearful of their own bodies and hypervigilant about position, which is associated with worse outcomes rather than better.

Sustained positions without variation. Low endurance in the muscles required to hold a position. Reduced overall movement volume. Sudden increases in a particular load.

The useful instruction is not 'sit up straight' but 'change position often and build the capacity to hold the positions you need'.

Endurance and strength in the trunk, shoulder girdle and hip muscles. Movement variety through the day. Graded exposure to the positions and tasks that currently provoke symptoms. Workstation setup as one factor among several rather than the whole answer.

Where a specific structural cause exists — scoliosis, spondylolisthesis, vertebral fracture — that is treated on its own terms rather than as posture.

We will not tell you your posture caused your pain, and we will not sell a programme to correct alignment that the evidence does not support correcting.

If your main complaint is appearance rather than pain or function, that is a legitimate goal and we will say honestly what exercise can and cannot change about it.

The link between static posture and pain is much weaker than the industry around it suggests. People with markedly forward heads and rounded shoulders frequently have no pain, and people with textbook alignment frequently do.

What does relate to symptoms is sustained position without variety, low load tolerance and weakness. So we train those, and we decline to sell a course of treatment aimed at changing how someone stands.

Mostly that the link is weaker and less direct than posture advice implies. A meta-analysis of 15 cross-sectional studies found that adults with neck pain held their heads further forward on average than adults without neck pain, while adolescents showed no such difference 2. Because studies of this kind measure posture and pain at the same moment, they cannot show which came first.

Sitting for long periods does tend to bring on back discomfort at the time, although it has not been established that it triggers clinical episodes of back pain 3. In controlled trials in healthy people, strengthening programmes changed posture measures in the upper back and neck, while stretching alone did not 4. For chronic low back pain, a Cochrane review of 249 trials found moderate-certainty evidence that exercise reduces pain compared with no treatment, usual care or placebo, although its effect on functional limitations was small 5.
