My time in clinical practice has shown me that most people want the immediate symptom of pain managed and will often not even realise there is an underlying cause. The professional insight into what might be driving their posture change, often facilitates any recovery to be sustained. If someone is subconsciously adopting a posture, making them aware of it means they can take ownership of it and learn to regularly move out of that posture to prevent excessive strain.
Posture is not a rigid concept. It represents something more fluid with considerable range for change.
In all instances I would recommend; simple changes to your daily life, including positioning, lifting technique, exercise tolerance, stress management and work-life balance, are all starting points.
It is also about considering both the physiological and psychological stressors. Failure to do this will inevitably lead to repeated episodes, a deepening perception of pain and a delayed recovery. When particularly troublesome, it may be necessary to seek appropriate advice from a qualified healthcare professional.
