Low Back Painbassendean-admin
This month’s newsletter is by our Senior Musculoskeletal Physiotherapist Dr Rob Waller. Rob has a special interest in spinal pain and has been author on multiple peer-reviewed publications on spinal pain. He also teaches at Curtin University, including in how to manage spinal pain, and has recently completed a PhD investigating pain mechanisms in young adults of the Raine Study (http://www.rainestudy.org.au).
Low back pain (LBP) is very common and is currently the leading cause of disability worldwide . Most adults will experience LBP as some point, with most episodes short lasting and recurrent episodes common. For nearly all people with back pain it is not possible to identify a specific anatomical source of pain . Only a very small proportion of people with LBP have serious pathology, such as vertebral fracture, cancer, infection or underlying inflammatory disorder, causing their pain. Unfortunately using a scan to identify the problem is not reliable because MRI abnormalities are as common in those with LBP as in those without. A common recommendation across all high quality LBP guidelines is routine imaging is discouraged unless serious pathology is suspected, it’s likely to change management (for e.g. surgery is being considered) or there has been a limited response to conservative care. There is no evidence routine imaging improves LBP outcomes.
If a specific anatomical cause for LBP is rarely identified, why do we get LBP? Pain is complex and defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage”. Low back pain is a symptom not a disease. Pain is the body’s warning system and can be associated with a real or perceived threat to the body. While this can be useful following injury, ongoing pain is not a good indicator of damage. While a specific anatomical cause for LBP is hard to identify, over loaded structures in the back can cause pain. However LBP and pain are complex with multiple contributors other than structure including;
- Psychological factors (stress, anxiety and depression can sensitize the nervous system)
- Social factors (eg seeing how others respond to pain),
- Beliefs (eg I need to protect my disc, my back is structurally vulnerable and I should not bend)
- Comorbidities: obesity, diabetes, other musculoskeletal pain
- Pain processing mechanisms: influenced by genetics and life experiences
- Interpreting pain as a threat, paying too much attention to pain (hypervigilance)
Key positive messages regarding LBP include:
- The causes of LBP are rarely serious
- LBP has a good prognosis
- Resuming normal activity as soon as reasonable is advised
- The back is a strong structure
- Pain does not equal harm
Key management principles include:
- Diagnosing LBP via a thorough examination and excluding serious causes
- Advice about what’s contributing to LBP and understanding why you have pain
- Strategies to self-manage pain including physical activity
- Treatment and exercise specific to the problem
- Medication when required but not as the primary management
The key message here is the clear majority of people with LBP, including leg pain (sciatica), will have a good outcome with evidence based, non-surgical care. At Bassendean Physiotherapy we pride ourselves on our accurate diagnosis and evidence based, contemporary management of LBP. We are happy to have a further discussion on the material presented here or provide the references.
