Chronic Low Back Pain Is Not a Prescription for Rest: Rebuilding Function Through Capacity and Load
Key takeaways
- Chronic low back pain is influenced by biological, functional, psychological and social factors; it is not defined by one scan or one posture.
- WHO, NICE and physical therapy guidance support education, remaining active, individualised exercise and shared decisions after urgent causes are considered.[1–3]
- BAIZE separates capacity from mechanical, physiological and psychological load so progress can be measured by meaningful function and recovery, not pain alone.
Evidence in context
The WHO guideline for chronic primary low back pain recommends person-centred, integrated care.[1] NICE and JOSPT guidance support education, activity and tailored exercise while reserving imaging for situations where the result may change management.[2,3]
BAIZE Clinical Interpretation
Capacity includes structural safety, strength and movement function, biological reserve, and recovery. Load includes work, lifting and training demands; sleep, illness and fatigue; and fear, distress or avoidance. A working BAIZE hypothesis is that symptoms may reflect a mismatch between current capacity and current demand. This is a clinical hypothesis to test with reassessment, not a diagnosis or promise of outcome.
Practical questions
Should I rest until the pain is gone?
Usually not. After urgent causes are excluded, graded activity and recovery planning are generally more useful than prolonged inactivity.[1–3]
Does a scan explain my pain?
Not by itself. Imaging must be interpreted alongside history, examination, neurological findings and function.
What should I track?
Track one or two meaningful activities, symptoms during and after the task, next-day recovery, sleep and function over time.
When is urgent assessment needed?
After major trauma, with progressive weakness or numbness, altered bladder or bowel function, fever with marked pain, unexplained weight loss or severe persistent night pain.
