It’s time for change with the 
management of non-specifi c 
chronic low back pain 
Peter O’Sullivan 
Low back pain (LBP) is the second great-est 
cause of disability in the USA. 1 USA 
data supports that in spite of an enormous 
increase in the health resources spent on 
LBP disorders, the disability relating to 
them continues to increase. 2 The man-agement 
of LBP is underpinned by the 
exponential increase in the use of physi-cal 
therapies, opiod medications, spinal 
injections as well as disc replacement 
and fusion surgery. 2 This is maintained 
by the underlying belief that LBP is fun-damentally 
a patho-anatomical disorder 
and should be treated within a biomedical 
model. 1 This is in spite of calls over a num-ber 
of years to adopt a bio-psycho-social 
approach, and evidence that only 8–15% 
of patients with LBP have an identifi ed 
patho-anatomical diagnosis, resulting in 
the majority being diagnosed as having 
non-specifi c LBP. 3 Of this population, 
a small but signifi cant group becomes 
chronic and disabled, labelled non-specifi c 
chronic low back pain (NSCLBP), consum-ing 
a disproportionate amount of health-care 
resources. 4 
1. Over the past decade, the traditional 
biomedical view of LBP has been 
greatly challenged. This is a result 
of: the failure of simplistic single-dimensional 
therapies to show large 
effects in patients with NSCLBP 5 – 8 ; 
2. the results of clinical trials testing 
commonly prescribed interventions 
demonstrating that no management 
approaches are clearly superior 5 – 7 9 ; 
3. the stories of NSCLBP patients relat-ing 
their own ongoing pain experi-ences 
of multiple failed treatments, 
confl icting diagnoses, lost hope and 
ongoing suffering 10 ; 
4. the indisputable evidence support-ing 
the multidimensional nature of 
NSCLBP as a disorder, where dis-ability 
levels are more closely associ-ated 
with cognitive and behavioural 
aspects of pain rather than sensory 
and biomedical ones 11 12 ; 
5. positive outcomes in randomised 
controlled trials (RCTs) are best pre-dicted 
by changes in psychological 
distress, fear avoidance beliefs, self-effi 
cacy in controlling pain and cop-ing 
strategies 13 14 ; 
6. the evidence supporting the broad 
subgrouping of NSCLBP disorders on 
the basis of neuro-physiological, 15 16 
cognitive, 17 physical factors 18 and 
lifestyle behaviours. 19 20 
Underlying primary healthcare clinical 
practice has been simplistic biomechani-cal 
and structural models of LBP and pelvic 
girdle pain (PGP), which focus on struc-tural 
diagnoses such as spinal and pelvic 
‘instability’. 21 22 These have been based 
on a belief that LBP and PGP is a result of 
structural (ie, degenerative), biomechani-cal 
and motor control defi cits resulting in 
segmental or regional ‘instability’ of the 
lumbo-pelvic region. 21 – 24 It is now clear 
that there is little evidence (basic sci-ence 
and outcome studies) to support the 
view that ‘instability’ underpins the basis 
of disabling NSCLBP. There are no stud-ies 
that demonstrate a clear relationship 
between spinal or pelvic mobility, degen-erative 
processes, pain and disability. 25 26 
Similarly, common patho-anatomical 
fi ndings such as degenerative disc disease, 
annular tears, fi ssures, facet joint arthrosis 
and disc bulges have been found not to be 
predictive of future LBP. 26 This highlights 
the limitation of radiological imaging and 
spinal structure to provide clear meaning 
to people’s experience of pain. Rather, fac-tors 
such as depression, 26 27 stress, cogni-tive 
and physical behaviours and lifestyle 
factors are more predictive of future LBP 
episodes. 11 20 
Yet in spite of this evidence, patients 
with disabling NSCLBP disorders continue 
to be provided with biomedical diagnoses 
and on the basis of these beliefs, people 
are prescribed with stabilising exercises, 
pelvic belts, supportive vests, spinal injec-tions 
or even stabilisation surgery. 1 2 23 28 
These ‘magic bullet’ approaches, for some, 
may in fact have the potential to drive 
fear, abnormal body focus and reinforce 
pain-related movement and avoidance 
behaviours, hypervigilance, catastrophis-ing, 
pain and disability fuelling the vicious 
cycle of pain. 29 
Diagnostic labels such as ‘instability’ 
should be reserved solely for ‘unstable frac-tures’ 
and ‘unstable spondylolisthesis’. 30 
The application of this diagnostic label to 
NSCLBP and PGP disorders is both inac-curate 
and potentially detrimental. 21 29 31 
This ‘belief system’, which I once advo-cated, 
has resulted in the development of 
an educational and management industry 
aimed at enhancing spinal stability for the 
prevention and treatment of NSCLBP, infl u-encing 
the practice of physiotherapy, allied 
health as well as sports rehabilitation and 
training industries across the world. 28 32 
This approach commonly instructs 
patients to contract their ‘stabilising’ mus-cles 
(pelvic fl oor and transverse abdominal 
wall and lumbar multifi dus) prior to spinal 
loading and during movement. 6 9 23 33 In 
sports and gym rehabilitation settings, 
patients are frequently instructed to brace 
their abdominal wall and back muscles, 
to create more spinal ‘stability’ with the 
belief that ‘more stability is better’. 
Yet these management approaches 
have not arrested the growing disabil-ity 
associated with NSCLBP. 2 Although 
there is evidence for the effi cacy of sta-bilising 
exercise for NSCLBP, 34 a number 
of high-quality RCTs have demonstrated 
that specifi c spinal stabilising exercises for 
NSCLBP are not superior to other conser-vative 
approaches 6 9 35 36 , they have small 
effect sizes 37 and they are only marginally 
better than placebo treatment consisting 
of detuned shortwave and ultrasound. 33 
Yet the benefi ts of this approach continue 
to be exclusively promoted, in spite of 
mounting scientifi c evidence that ques-tions 
the underlying basis of this clini-cal 
belief system. This includes evidence 
that the motor control characteristics of 
non-specifi c low back pain (NSLBP) and 
NSCLBP commonly lie in fi ndings of: 
1. increased co-contraction (stability) of 
trunk muscles 38 39 and guarded spinal 
movement 40 ; 
2. hyperactivity of trunk muscles 
(including muscles such as erector 
spinae, lumbar multifi dus, pelvic 
fl oor and transverse abdominal wall) 
in NSCLBP and PGP disorders 18 41 42 ; 
3. an inability of the back muscles to 
relax 18 40 ; 
4. a tendency for earlier onsets of the 
antero-lateral abdominal wall mus-cles 
during rapid arm movements 
rather than timing delays 43 ;

5. in some cases, trunk muscle hypertro-phy 
in muscles such as lumbar mul-tifi 
dus 44 and quadratus lumborum 45 
have been documented in LBP sport 
populations. 
Further to this, there is evidence for: 
1. a lack of association between muscle 
density (degeneration) of lumbar 
multifudus and LBP in a recent large 
population study 46 ; 
2. a lack of association between changes 
in transversus abdominus muscle tim-ing 
47 and lumbar multifi dus cross-sec-tional 
area 13 as a predictor of positive 
outcomes (disability levels) in RCTs. 
This body of research challenges current 
practice and beliefs and is a counter view 
to previous literature. Some of the appar-ent 
confl ict within the literature appears 
to have arisen where the results of stud-ies 
with small sample sizes, investigating 
subjects with recurrent LBP 48 49 , have been 
extrapolated to the broad NSCLBP popu-lation 
without the results of these studies 
being reproduced in these populations or 
in larger groups. 
The physiotherapy, manual therapy and 
medical professions have long focused 
on trying to fi nd the magic ‘technique’, 
‘muscle’, ‘injection’ or ‘surgical technique’ 
required to solve the problem of NSCLBP 
and PGP disorders. This reductionist 
approach to dealing with complex disor-ders 
in a simplistic manner clearly hasn’t 
delivered for our patients 50 and contradicts 
current knowledge that NSCLBP should 
be considered within a multidimensional 
bio-psycho-social framework. In fact, it 
has been proposed that single-dimen-sional 
approaches may in fact exacerbate 
chronic disorders reinforcing a cumulative 
feedback loop. 29 
In response to the calls to manage 
NSCLBP from a bio-psycho-social per-spective, 
a number of RCTs have tested 
cognitive behavioural approaches to more 
effectively manage the disorder. Yet sys-tematic 
reviews of these approaches have 
failed to demonstrate greater effi cacy than 
other active conservative approaches in 
managing NSCLBP. 51 Possible reasons 
for this failure may relate to the lack of 
patient-centred and targeted manage-ment 
52 as well as a failure to address other 
dimensions such as neuro-physiological 
factors and maladaptive lifestyle and 
movement behaviours known to be asso-ciated 
with NSCLBP disorders. 18 20 30 
There is strong evidence that NSCLBP 
disorders are associated with a complex 
combination of physical behavioural, 
lifestyle, neuro-physiological (peripheral 
and central nervous system changes), 
psychological/cognitive and social fac-tors. 
12 20 30 These factors together have the 
potential to promote maladaptive cognitive 
behaviours (negative beliefs, fear, avoid-ance, 
catastrophising, hypervigilance), 53 
pain behaviours (pain communicative and 
avoidant behaviours) 54 and movement 
behaviours, 30 setting up a vicious cycle 
of pain sensitisation and reinforcing dis-ability. 
Changes in immune and neuro-endocrine 
function linked to altered stress 
responsiveness coupled with activation of 
the pain neuro-matrix in the brain may 
result in tissue hyperalgesia and altered 
neuro-muscular responses. 11 It is thought 
that these processes are mediated by envi-ronmental/ 
genetic interactions. 55 
The balance and contribution of these 
different factors will likely vary for each 
individual. For example, it is known that 
not all NSCLBP disorders are associated 
with signifi cant psychosocial factors. 17 56 
However, there is strong evidence that 
disability and factors such as sick leave are 
best predicted by factors such as negative 
back pain beliefs, fear and distress. 17 57 
Futhermore, psychological factors such as 
fear and catastrophising commonly asso-ciated 
with disabling pain have lifestyle, 
physical, neuro-muscular 40 as well as neu-ro- 
biological consequences, highlighting 
that the mind and the body are inextrica-bly 
linked. 11 
There is also growing evidence that 
NSCLBP disorders can be broadly cat-egorised 
or subgrouped based on different 
psychosocial/coping behaviours, 17 58 59 
neuro-physiological characteristics, 15 56 
pain behaviours 54 and movement 
behaviours, 18 30 providing greater poten-tial 
for targeting of multidimensional 
interventions. 60 These broad subgroups, 
rather than being rigid entities which are 
characterised by prediction rules, 61 may 
provide a framework for the clinician to 
tailor management to patients in a more 
targeted person- centred multidimensional 
manner. 30 58 59 
There is emerging evidence to support 
this view that patient-centred multidimen-sional 
targeted behavioural approaches 
have greater effi cacy than current practice 
for the management of NSCLBP disorders 
in primary care settings. Asenlöf et al 62 63 
compared individually tailored treatment 
targeting activity levels, motor behaviour 
and cognitions, demonstrating superior 
outcomes to exercise therapy. A patient-centred 
multidimensional behavioural 
approach called ‘classifi cation-based cog-nitive 
functional therapy’ that targets 
maladaptive cognitive, lifestyle, pain and 
movement behaviours was more effective 
(greater effect sizes) than manual therapy 
and exercise for localised NSCLBP. 64 Hill 
et al 65 employed a patient-centred strati-fi 
cation approach to target physiotherapy 
treatment based on psychosocial risk pro-fi 
le, demonstrating superior outcomes and 
cost saving over standard physiotherapy 
care. Further research into this patient-centred 
multidimensional approach is 
clearly required but recent evidence is 
encouraging for improved outcomes. 
Other behavioural therapies such as 
mindfulness meditation, 66 acceptance and 
commitment therapy, 67 brain-directed 
therapies 68 69 and targeted medical man-agement 
70 hold hope for the multidisci-plinary 
management of some of the highly 
complex and disabling central nervous 
system pain disorders. 
In spite of this emerging evidence, 
recent research highlights that health 
professionals dealing with LBP disorders 
have diffi culty accurately identifying 
psycho-social risk in their patients, limit-ing 
their capacity to target management. 71 
It appears that specifi c training in behav-ioural 
aspects of a patients presentation 
is required to enable health professionals 
to identify psycho-social risk factors and 
maladaptive movement behaviours from 
a clinical examination. 72 There is also 
growing evidence to support the criti-cal 
role that the quality of the therapeu-tic 
relationship plays in the management 
of pain disorders. 73 Practitioner-related 
factors such as communication skills, 
empathy, level of confi dence and beliefs 
have an important infl uence on patient 
outcomes and compliance to treatment. 74 
Conversely, patient beliefs and expecta-tions 
also have a profound infl uence on 
health disorder outcomes. 75 
With all this in mind, the challenges for 
the future in more effectively dealing with 
NSCLBP disorders are likely to involve 
primary healthcare providers shifting rig-idly 
held biomedical beliefs and develop-ing 
greater skills and knowledge across a 
number of domains. These skills are likely 
to include: 
1. Greater understanding of the complex 
multidimensional nature of NSCLBP. 
2. Developing diagnostic skills to clearly 
differentiate specifi c pathology as a 
driver of pain from NSLBP disorders. 
3. Develop more effective communica-tion 
skills utilising empathy, refl ec-tive 
questioning and motivational 
interviewing techniques in order 
to listen to the patients’ story and 
explore their pain beliefs, fears, 
coping strategies, life stresses, psy-cho- 
social factors, pain behaviour, 
impairments and goals. This allows

for the development of an effective 
therapeutic relationship and the accu-rate 
interpretation of clinical infor-mation 
within a bio-psycho-social 
framework in order to identify the 
primary drivers of pain and disability. 
This in turn provides the capacity to 
clearly outline the vicious cycle of the 
disorder in a patient-centred way. 
4. I dentifi cation of maladaptive cog-nitive 
behaviours (negative beliefs, 
stress responsiveness, provocative 
coping strategies, hypervigilance, 
fear, catastrophising, anxiety, depres-sion 
etc). 
5. Identifying neuro-physiological pro-cesses 
such as central and peripheral 
sensitisation. 
6. The analysis and interpretation of pain 
communicative and avoidant behav-iours 
54 and movement and postural 
behaviours 30 in order to determine 
adaptive (protective) from maladap-tive 
(provocative) behaviours. 30 
7. Synthesising and interpreting clini-cal 
information across multiple 
domains. 
8. Developing multidimensional and 
fl exible interventions that target 
maladaptive cognitive, lifestyle, pain 
and movement behaviours in an inte-grated 
manner. 
9. Facilitation of behavioural change in 
patients by enhancing clinical skills 
such as empathy, motivation, sup-port, 
creativity, goal setting, fl exible 
person-centred functional rehabilita-tion 
programmes and clear feedback. 
10. Developing clear multidisciplinary 
approaches to management where 
indicated. 
11. Developing a broad framework for 
subgrouping of NSCLBP patients 
from a multidimensional perspec-tive. 
17 30 52 58 This will allow the 
broad categorisation of LBP disorders 
based on the presence of dominant 
psycho-social, neuro-physiological, 
lifestyle and movement behaviours 
that act as drivers for the disorder. 
12. Adopting the routine use of screening 
tools in clinical practice in order to 
identify risk and targets for change to 
better direct management. 65 76 
This approach will likely focus less on 
treating the structure or signs and symp-toms 
of a disorder in NSCLBP disorders 
and more on targeting the different combi-nations 
of beliefs, cognitive, pain, lifestyle 
and movement behaviours that underlie 
and drive disorders. Implementation of 
this approach will require a paradigm 
shift in ‘beliefs’ of health professionals 
in terms of how we understand and deal 
with NSCLBP disorders. This will involve 
abandoning ineffective practices, learning 
new skills, adopting and integrating new 
approaches. This new knowledge and 
skill needs to be trained at undergradu-ate 
and graduate levels and promoted 
actively within the professions that deal 
with these disorders. 77 There is also a 
mandate to educate the public in order to 
reinforce more positive back pain beliefs 
to reduce the burden for both individu-als 
and society. 78 This will invariably lead 
to health insurers abandoning the ongo-ing 
funding of non-effi cacious treatment 
approaches. 
Further research is clearly needed to bet-ter 
identify the underlying mechanisms 
associated with disabling NSCLBP dis-orders 
and their development across the 
lifespan. This will likely involve a greater 
understanding of genetic/environmental 
interactions associated with the devel-opment 
of the nervous system, tissue 
sensitisation and associated maladaptive 
behaviours, tracking from early life to ado-lescence 
and into adulthood. Developing 
a greater understanding of those people 
resilient to these disorders may also be 
illuminating. Early screening and targeted 
management of risk groups, based on 
the identifi cation of the mechanisms that 
drive them, may aid in the prevention of 
pain chronicity and disability. Innovative 
multidimensional, patient-centred and 
targeted approaches to management for 
these complex disorders need to be further 
developed and adequately tested. 
Characteristics such as hope, positive 
help seeking and adaptability are traits 
of resilience that we need to equip our 
patients with, who suffer with disabling 
NSCLBP. 12 Adopting a positive multi-dimensional 
perspective of health that 
is person focused may allow us to view 
NSCLBP in a new light, providing hope 
for our patients and an environment for 
innovation, discovery and change.

  • 1. Editorial Downloaded from bjsm.bmj.com on August 7, 2011 - Published by group.bmj.com BJSM Online First, published on August 4, 2011 as 10.1136/bjsm.2010.081638 It’s time for change with the management of non-specifi c chronic low back pain Peter O’Sullivan Low back pain (LBP) is the second great-est cause of disability in the USA. 1 USA data supports that in spite of an enormous increase in the health resources spent on LBP disorders, the disability relating to them continues to increase. 2 The man-agement of LBP is underpinned by the exponential increase in the use of physi-cal therapies, opiod medications, spinal injections as well as disc replacement and fusion surgery. 2 This is maintained by the underlying belief that LBP is fun-damentally a patho-anatomical disorder and should be treated within a biomedical model. 1 This is in spite of calls over a num-ber of years to adopt a bio-psycho-social approach, and evidence that only 8–15% of patients with LBP have an identifi ed patho-anatomical diagnosis, resulting in the majority being diagnosed as having non-specifi c LBP. 3 Of this population, a small but signifi cant group becomes chronic and disabled, labelled non-specifi c chronic low back pain (NSCLBP), consum-ing a disproportionate amount of health-care resources. 4 1. Over the past decade, the traditional biomedical view of LBP has been greatly challenged. This is a result of: the failure of simplistic single-dimensional therapies to show large effects in patients with NSCLBP 5 – 8 ; 2. the results of clinical trials testing commonly prescribed interventions demonstrating that no management approaches are clearly superior 5 – 7 9 ; 3. the stories of NSCLBP patients relat-ing their own ongoing pain experi-ences of multiple failed treatments, confl icting diagnoses, lost hope and ongoing suffering 10 ; 4. the indisputable evidence support-ing the multidimensional nature of NSCLBP as a disorder, where dis-ability levels are more closely associ-ated with cognitive and behavioural aspects of pain rather than sensory and biomedical ones 11 12 ; 5. positive outcomes in randomised controlled trials (RCTs) are best pre-dicted by changes in psychological distress, fear avoidance beliefs, self-effi cacy in controlling pain and cop-ing strategies 13 14 ; 6. the evidence supporting the broad subgrouping of NSCLBP disorders on the basis of neuro-physiological, 15 16 cognitive, 17 physical factors 18 and lifestyle behaviours. 19 20 Underlying primary healthcare clinical practice has been simplistic biomechani-cal and structural models of LBP and pelvic girdle pain (PGP), which focus on struc-tural diagnoses such as spinal and pelvic ‘instability’. 21 22 These have been based on a belief that LBP and PGP is a result of structural (ie, degenerative), biomechani-cal and motor control defi cits resulting in segmental or regional ‘instability’ of the lumbo-pelvic region. 21 – 24 It is now clear that there is little evidence (basic sci-ence and outcome studies) to support the view that ‘instability’ underpins the basis of disabling NSCLBP. There are no stud-ies that demonstrate a clear relationship between spinal or pelvic mobility, degen-erative processes, pain and disability. 25 26 Similarly, common patho-anatomical fi ndings such as degenerative disc disease, annular tears, fi ssures, facet joint arthrosis and disc bulges have been found not to be predictive of future LBP. 26 This highlights the limitation of radiological imaging and spinal structure to provide clear meaning to people’s experience of pain. Rather, fac-tors such as depression, 26 27 stress, cogni-tive and physical behaviours and lifestyle factors are more predictive of future LBP episodes. 11 20 Yet in spite of this evidence, patients with disabling NSCLBP disorders continue to be provided with biomedical diagnoses and on the basis of these beliefs, people are prescribed with stabilising exercises, pelvic belts, supportive vests, spinal injec-tions or even stabilisation surgery. 1 2 23 28 These ‘magic bullet’ approaches, for some, may in fact have the potential to drive fear, abnormal body focus and reinforce pain-related movement and avoidance behaviours, hypervigilance, catastrophis-ing, pain and disability fuelling the vicious cycle of pain. 29 Diagnostic labels such as ‘instability’ should be reserved solely for ‘unstable frac-tures’ and ‘unstable spondylolisthesis’. 30 The application of this diagnostic label to NSCLBP and PGP disorders is both inac-curate and potentially detrimental. 21 29 31 This ‘belief system’, which I once advo-cated, has resulted in the development of an educational and management industry aimed at enhancing spinal stability for the prevention and treatment of NSCLBP, infl u-encing the practice of physiotherapy, allied health as well as sports rehabilitation and training industries across the world. 28 32 This approach commonly instructs patients to contract their ‘stabilising’ mus-cles (pelvic fl oor and transverse abdominal wall and lumbar multifi dus) prior to spinal loading and during movement. 6 9 23 33 In sports and gym rehabilitation settings, patients are frequently instructed to brace their abdominal wall and back muscles, to create more spinal ‘stability’ with the belief that ‘more stability is better’. Yet these management approaches have not arrested the growing disabil-ity associated with NSCLBP. 2 Although there is evidence for the effi cacy of sta-bilising exercise for NSCLBP, 34 a number of high-quality RCTs have demonstrated that specifi c spinal stabilising exercises for NSCLBP are not superior to other conser-vative approaches 6 9 35 36 , they have small effect sizes 37 and they are only marginally better than placebo treatment consisting of detuned shortwave and ultrasound. 33 Yet the benefi ts of this approach continue to be exclusively promoted, in spite of mounting scientifi c evidence that ques-tions the underlying basis of this clini-cal belief system. This includes evidence that the motor control characteristics of non-specifi c low back pain (NSLBP) and NSCLBP commonly lie in fi ndings of: 1. increased co-contraction (stability) of trunk muscles 38 39 and guarded spinal movement 40 ; 2. hyperactivity of trunk muscles (including muscles such as erector spinae, lumbar multifi dus, pelvic fl oor and transverse abdominal wall) in NSCLBP and PGP disorders 18 41 42 ; 3. an inability of the back muscles to relax 18 40 ; 4. a tendency for earlier onsets of the antero-lateral abdominal wall mus-cles during rapid arm movements rather than timing delays 43 ; Correspondence to Professor Peter O’Sullivan, Professor/Specialist Musculoskeletal Physiotherapist, Curtin University, GPO Box U1987, Perth, WA 6845, Australia; p.osullivan@curtin.edu.au Copyright Article author (or their employer) 2011.

Editorial Downloaded from bjsm.bmj.com on August 7, 2011 - Published by group.bmj.com 5. in some cases, trunk muscle hypertro-phy in muscles such as lumbar mul-tifi dus 44 and quadratus lumborum 45 have been documented in LBP sport populations. Further to this, there is evidence for: 1. a lack of association between muscle density (degeneration) of lumbar multifudus and LBP in a recent large population study 46 ; 2. a lack of association between changes in transversus abdominus muscle tim-ing 47 and lumbar multifi dus cross-sec-tional area 13 as a predictor of positive outcomes (disability levels) in RCTs. This body of research challenges current practice and beliefs and is a counter view to previous literature. Some of the appar-ent confl ict within the literature appears to have arisen where the results of stud-ies with small sample sizes, investigating subjects with recurrent LBP 48 49 , have been extrapolated to the broad NSCLBP popu-lation without the results of these studies being reproduced in these populations or in larger groups. The physiotherapy, manual therapy and medical professions have long focused on trying to fi nd the magic ‘technique’, ‘muscle’, ‘injection’ or ‘surgical technique’ required to solve the problem of NSCLBP and PGP disorders. This reductionist approach to dealing with complex disor-ders in a simplistic manner clearly hasn’t delivered for our patients 50 and contradicts current knowledge that NSCLBP should be considered within a multidimensional bio-psycho-social framework. In fact, it has been proposed that single-dimen-sional approaches may in fact exacerbate chronic disorders reinforcing a cumulative feedback loop. 29 In response to the calls to manage NSCLBP from a bio-psycho-social per-spective, a number of RCTs have tested cognitive behavioural approaches to more effectively manage the disorder. Yet sys-tematic reviews of these approaches have failed to demonstrate greater effi cacy than other active conservative approaches in managing NSCLBP. 51 Possible reasons for this failure may relate to the lack of patient-centred and targeted manage-ment 52 as well as a failure to address other dimensions such as neuro-physiological factors and maladaptive lifestyle and movement behaviours known to be asso-ciated with NSCLBP disorders. 18 20 30 There is strong evidence that NSCLBP disorders are associated with a complex combination of physical behavioural, lifestyle, neuro-physiological (peripheral and central nervous system changes), psychological/cognitive and social fac-tors. 12 20 30 These factors together have the potential to promote maladaptive cognitive behaviours (negative beliefs, fear, avoid-ance, catastrophising, hypervigilance), 53 pain behaviours (pain communicative and avoidant behaviours) 54 and movement behaviours, 30 setting up a vicious cycle of pain sensitisation and reinforcing dis-ability. Changes in immune and neuro-endocrine function linked to altered stress responsiveness coupled with activation of the pain neuro-matrix in the brain may result in tissue hyperalgesia and altered neuro-muscular responses. 11 It is thought that these processes are mediated by envi-ronmental/ genetic interactions. 55 The balance and contribution of these different factors will likely vary for each individual. For example, it is known that not all NSCLBP disorders are associated with signifi cant psychosocial factors. 17 56 However, there is strong evidence that disability and factors such as sick leave are best predicted by factors such as negative back pain beliefs, fear and distress. 17 57 Futhermore, psychological factors such as fear and catastrophising commonly asso-ciated with disabling pain have lifestyle, physical, neuro-muscular 40 as well as neu-ro- biological consequences, highlighting that the mind and the body are inextrica-bly linked. 11 There is also growing evidence that NSCLBP disorders can be broadly cat-egorised or subgrouped based on different psychosocial/coping behaviours, 17 58 59 neuro-physiological characteristics, 15 56 pain behaviours 54 and movement behaviours, 18 30 providing greater poten-tial for targeting of multidimensional interventions. 60 These broad subgroups, rather than being rigid entities which are characterised by prediction rules, 61 may provide a framework for the clinician to tailor management to patients in a more targeted person- centred multidimensional manner. 30 58 59 There is emerging evidence to support this view that patient-centred multidimen-sional targeted behavioural approaches have greater effi cacy than current practice for the management of NSCLBP disorders in primary care settings. Asenlöf et al 62 63 compared individually tailored treatment targeting activity levels, motor behaviour and cognitions, demonstrating superior outcomes to exercise therapy. A patient-centred multidimensional behavioural approach called ‘classifi cation-based cog-nitive functional therapy’ that targets maladaptive cognitive, lifestyle, pain and movement behaviours was more effective (greater effect sizes) than manual therapy and exercise for localised NSCLBP. 64 Hill et al 65 employed a patient-centred strati-fi cation approach to target physiotherapy treatment based on psychosocial risk pro-fi le, demonstrating superior outcomes and cost saving over standard physiotherapy care. Further research into this patient-centred multidimensional approach is clearly required but recent evidence is encouraging for improved outcomes. Other behavioural therapies such as mindfulness meditation, 66 acceptance and commitment therapy, 67 brain-directed therapies 68 69 and targeted medical man-agement 70 hold hope for the multidisci-plinary management of some of the highly complex and disabling central nervous system pain disorders. In spite of this emerging evidence, recent research highlights that health professionals dealing with LBP disorders have diffi culty accurately identifying psycho-social risk in their patients, limit-ing their capacity to target management. 71 It appears that specifi c training in behav-ioural aspects of a patients presentation is required to enable health professionals to identify psycho-social risk factors and maladaptive movement behaviours from a clinical examination. 72 There is also growing evidence to support the criti-cal role that the quality of the therapeu-tic relationship plays in the management of pain disorders. 73 Practitioner-related factors such as communication skills, empathy, level of confi dence and beliefs have an important infl uence on patient outcomes and compliance to treatment. 74 Conversely, patient beliefs and expecta-tions also have a profound infl uence on health disorder outcomes. 75 With all this in mind, the challenges for the future in more effectively dealing with NSCLBP disorders are likely to involve primary healthcare providers shifting rig-idly held biomedical beliefs and develop-ing greater skills and knowledge across a number of domains. These skills are likely to include: 1. Greater understanding of the complex multidimensional nature of NSCLBP. 2. Developing diagnostic skills to clearly differentiate specifi c pathology as a driver of pain from NSLBP disorders. 3. Develop more effective communica-tion skills utilising empathy, refl ec-tive questioning and motivational interviewing techniques in order to listen to the patients’ story and explore their pain beliefs, fears, coping strategies, life stresses, psy-cho- social factors, pain behaviour, impairments and goals.

This in turn provides the capacity to clearly outline the vicious cycle of the disorder in a patient-centred way. 4.

Facilitation of behavioural change in patients by enhancing clinical skills such as empathy, motivation, sup-port, creativity, goal setting, fl exible person-centred functional rehabilita-tion programmes and clear feedback. 10. Developing clear multidisciplinary approaches to management where indicated. 11. Developing a broad framework for subgrouping of NSCLBP patients from a multidimensional perspec-tive. 17 30 52 58 This will allow the broad categorisation of LBP disorders based on the presence of dominant psycho-social, neuro-physiological, lifestyle and movement behaviours that act as drivers for the disorder. 12. Adopting the routine use of screening tools in clinical practice in order to identify risk and targets for change to better direct management. 65 76 This approach will likely focus less on treating the structure or signs and symp-toms of a disorder in NSCLBP disorders and more on targeting the different combi-nations of beliefs, cognitive, pain, lifestyle and movement behaviours that underlie and drive disorders. Implementation of this approach will require a paradigm shift in ‘beliefs’ of health professionals in terms of how we understand and deal with NSCLBP disorders. This will involve abandoning ineffective practices, learning new skills, adopting and integrating new approaches. This new knowledge and skill needs to be trained at undergradu-ate and graduate levels and promoted actively within the professions that deal with these disorders. 77 There is also a mandate to educate the public in order to reinforce more positive back pain beliefs to reduce the burden for both individu-als and society. 78 This will invariably lead to health insurers abandoning the ongo-ing funding of non-effi cacious treatment approaches. Further research is clearly needed to bet-ter identify the underlying mechanisms associated with disabling NSCLBP dis-orders and their development across the lifespan. This will likely involve a greater understanding of genetic/environmental interactions associated with the devel-opment of the nervous system, tissue sensitisation and associated maladaptive behaviours, tracking from early life to ado-lescence and into adulthood. Developing a greater understanding of those people resilient to these disorders may also be illuminating. Early screening and targeted management of risk groups, based on the identifi cation of the mechanisms that drive them, may aid in the prevention of pain chronicity and disability. Innovative multidimensional, patient-centred and targeted approaches to management for these complex disorders need to be further developed and adequately tested. Characteristics such as hope, positive help seeking and adaptability are traits of resilience that we need to equip our patients with, who suffer with disabling NSCLBP. 12 Adopting a positive multi-dimensional perspective of health that is person focused may allow us to view NSCLBP in a new light, providing hope for our patients and an environment for innovation, discovery and change.
