time course of back pain
Time course of back pain
  • LBP is a recurrent phenomenon
    • at all ages
  • Untidy pattern across the life course with variable periodicity and severity.
  • Coexisting symptoms (physical and mental) common
  • Are chronic cases such from beginning or are they result of failed early treatment??

epidemiology in low back pain
Epidemiology in low back pain

Symptom not a disease

cause unexplained in 85%

data are self-reported - questionnaires:

tell us about how people experience LBP

different questions give different numbers

Consequences more of a problem than symptoms

care seeking

sick leave

disability

Low back pain is a common complaint among adolescents.

similar pattern to adults

health problem does not equal a medical problem
Health problem does NOT equal a medical problem
  • Reasons for care seeking are complex
  • Person not always seeking a fix
  • Reassurance may be enough
    • 'My back hurts, but the reason I'm here is that I can't cope on my own any longer' (Hadler 1999)
genetics individual
Genetics / Individual

Twins studies, controlling for environmental (occupational) factors:

70% of disc degeneration associated with genetic factors

Heritability of back pain possibly >50%

Muscle strength and level of fitness have little influence

the overall perspective
The overall perspective

Societal burden equal to depression, heart diseases or diabetes

Production loss (due to absenteeism and disability) far greatest impact

back pain epidemiology key messages
Back Pain EpidemiologyKey Messages
    • LBP- Data demonstrate substantial nonbiologic influences
  • Heritability of back pain possibly higher than 50%
    • 70% of disc degeneration associated with genetic factors
    • Production loss (due to absenteeism and disability) has the greatest impact on the ecmonic burden of back pain
    • An early investment in correct evidence based care can generate long term cost saving.

Cascade of care
  • Simple to complex
  • Bothersomeness and function

  • Evidence based
  • FUNCTIONAL RESTORATION PROGRAMS

UK occupational health guidelines
  • Individual psychosocial findings are a risk factor for the incidence (onset) of LBP, but overall the size of the effect is small.
  • Unsatisfactory psychosocial aspects of work are risk factors for reported LBP, health care use, and work loss, but the effect size is modest.
  • Individual and psychosocial aspects of work play an important role in persisting symptoms and disability, and also influence response to treatment.

Carter & Birrell 2000: www.facoccmed.ac.uk

work caused or work relevant
Work caused or work-relevant?
  • Whilst some (episodes of) low back pain may be caused by work, most are not.
  • Yet, symptoms may affect workability
    • work can be difficult/painful because of symptoms
      • consequences are driven more by psychosocial than physical factors.
  • LBP may be highly work-relevant, irrespective of cause.
acute low back pain
Acute Low Back Pain
  • Simple Back ache
  • Nerve root pain
  • Possible serious spine pathology
  • Cauda equina syndrome

Questions to ask

When you are in pain do you think it is terrible and will never get better?

Does pain feel overwhelming to you?

  • Identify interpretations of symptoms bodily sensations or persons situation that are out of proportion
  • This leads the patient to a sense of unease
  • A lack of feeling of control
mixed messages
MIXED MESSAGES
  • Cconflicting diagnosis or explanations for back pain
  • Dramatisation of back pain by health professionals

  • Work history job dissatisfaction, frequent changes

Chronic Low Back Pain

A Heterogeneous Condition With Challenges for an Evidence-Based Approach

degenerative mri changes in patients with clbp
Degenerative MRI Changes in Patients WithCLBP
  • There is insufficient evidence to support the routine use of MRI
    • Strength of recommendation: Strong
  • Surgical treatment of CLBP based exclusively on MRI findings of degenerative changes is not recommended.
    • Strength of recommendation: Strong
key points
Key Points
  • Current low back pain management is fragmented into five major management spheres, which have little or no interactions with one another.
  • Chronic LBP is a heterogeneous condition and this affects the way it is diagnosed, classified, treated,andstudied.
  • While nonoperative approaches are the mainstay of management of LBP, surgery offers improved outcomes in carefully selected patients.
  • There is an urgent need for large national registries to track the natural history and outcomes of treatments for chronic LBP.
