Clinical scenario
•  Patient reports
   –  “My backs out”
   –  “The doctor says it’s a muscle strain”
   –  “The doctor says I’ll get better but its now 6 weeks”

•  Clinical questions
   –    Does it matter which treatment I provide?
   –    How do I diagnose the problem?
   –    What treatment can I provide that is specific to the diagnosis?
   –    Is there evidence to support these clinical decisions?
Clinical practice guidelines
•  Syntheses of CPGs (Dagenais et al 2010, Koes et
   al 2010)
•  High quality guidelines from last 10 years
   (average 4 years old)
Recommendations
•  Identify “flags”
What is “organic pathology”
•  Typically regarded as disc herniation with
   associated radiculopathy (DHR)
   –  Conservative trial followed by surgery if non-responsive
   –  MRI not indicated unless surgery being seriously
      considered
•  Potential counter-productive effect of attempting
   to identify pathoanatomical cause of the pain
   (beyond serious pathology including DHR)
Specific treatment
               recommendations
•  Specific treatment for organic pathology other
   than DHR not provided
•  Treatment specific to the flag identified not
   clearly stated
•  Due to low level evidence on the efficacy of
   specific treatment
   –  eg Which treatment is most effective for
      •  High fear avoidance beliefs?
      •  Disc herniation with associated radiculopathy?
Generic treatment
                recommendations
•  Advice/reassurance for acute LBP ± medication
   for short term relief
•  Chronic LBP
  –    Exercise
  –    Cognitive behavioural approach
  –    Multi-disciplinary intervention
  –    Acupuncture
  –    Opiates
•  Variable recommendations for manual therapy
   due to lack of consistent evidence
Lack of evidence
•    Diagnostic injection
•    Therapeutic blocks
•    Pilates
•    Massage therapy
•    Specific treatment (eg SIJ, O’Sullivan, McKenzie,
     motor control, etc)
And there’s more…
•  Treatment effects are small (less than 0.5) when
   compared to “minimal intervention” or “usual
   care”
  –  Borderline clinical meaningfulness
•  Non-significant treatment effects comparing one
   treatment to another
Classification issues (aka lumping
            and splitting)

•  False assumption of sample
   homogeneity
•  Application of generic
   treatment protocols
•  Dilution of the effect of
   specific treatment
Are these treatments appropriate
     for all “non-specific LBP” cases?
•    Motor control
•    Manual therapy
•    Pilates
•    McKenzie
•    Functional restoration/graded activity
•    Cognitive-behavioural approach
•    Neurophysiological education
•    Treatment of signs and symptoms

Classification RCTs

The effectiveness of physiotherapy functional
restoration for post-acute low back pain (Richards,
Ford et al 2012) – in press
Recent advances in classification
•  Peter O’Sullivan
   –  Movement and control impairment subgroups
   –  Exercise, motor control, cognitive-behavioural Rx
•  STaRT Back
   –  Orebro based subgroups of low, mod and high risk
   –  Advise/functional restoration/cognitive behavioural Rx
•  Tom Petersen/Mark Laslett
   –  Pathoanatomical subgroups
   –  McKenzie treatment for discogenic pain
Identified issues
•  Mixing populations
•  Reinventing the wheel – what about manual
   therapy?
•  Complexity (O’Sullivan)
•  Poorly described and non-reproducible treatment
   protocols
•  “Forcing” patients into one subgroup (O’Sullivan
   and McKenzie)
The STOPS approach
•  The right population - sub-acute, non-
   compensable
•  Well accepted/validated subgroups
   –    Reducible discogenic pain
   –    Disc herniation with associated radiculopathy
   –    Z-joint dysfunction
   –    Non-reducible discogenic pain
   –    Multi-factorial persistent pain
•  A sophisticated but well described and
   reproducible assessment and classification
   system
