Introduction: One expression of the social conscience of chiropractic is the provision by chiropractic educational institutions of low-cost or free chiropractic care to disadvantaged communities. It is expected that institutions offer to all patients the same full standard of care that is the hallmark of traditional chiropractic.
Objective: To explore whether an observed schism occurring within chiropractic education, where a minority of institutions are minimising the major premise of the discipline and replacing it with an emphasis on only the science or literature component of the evidence-based triad, has any potential impact on the quality of care provided particularly within the charitable context.
Data Sources and Synthesis: The indexed literature supplemented by informal literature, news reports, URLs identified by on-line searching, personal communication and key informants. A contextual narrative identifies themes which combine to suggest the healing component of the chiropractic encounter may be compromised. Concern is also expressed that students in those institutions which have removed the major premise of chiropractic from their curriculum may experience compromise in their learning which may negatively impact patient care.
Conclusion: The social conscience of chiropractic may be compromised by undue emphasis on science and the relegation of traditional concepts as historical artefacts. Academic chiropractors seem yet to address potential consequences.

From the FULL TEXT Article:
Introduction
The general understanding of social conscience is being aware of problems that affect
people in society and involves an attitude of sensitivity and responsibility toward them.
This is typically reflected in chiropractic educational programs by offering lower cost
healthcare to the public through an on-campus clinic and ‘gold-coin’ or other donation
system for care delivered in outreach clinics. These may include missionary-style visits to
remote communities in other countries. It is thought that academic and clinical
chiropractors may best lead students by example. A relevant question that arises is how a
social conscience to do good is enacted, in particular for chiropractic students, and
whether it is by application of the major premise of chiropractic which includes a
contemporary concept of subluxation or by a mode of chiropractic that excludes
subluxation on the basis it is not evidence-based?
Evidence-based medicine (EBM) was conceptualised in mid-19th century Paris and given
life by Sackett in the 1990s as a mechanism to formalise science within the healing
equation between the practitioner and the patient. [1] Over the past decade some
academic chiropractors have placed increasing emphasis on the science component to the
detriment of the others. The discipline of chiropractic was founded about a century ago
from medical concepts first reported in the early 19th century. Its major premise holds that
small dysfunctions between vertebrae loosely considered ‘subluxations’ may effect
neurophysiological change that may be corrected by targeted therapeutic input considered
as the ‘chiropractic adjustment.’
Globally there are today some 46 or so universities and institutions which teach the
discipline [2] and I believe a schism is occurring among them. This paper does not attempt
to determine the growth point at which any health discipline becomes large enough to
diverge in its teachings; rather, it is a reflection on an observed divergence and an attempt
to narrate underlying factors that render such a divergence of value or not. The core
question is the extent to which this divergence may damage the social conscience of
chiropractic as enacted by the provision of care for less-privileged patients within a globally
accepted healthcare profession.
The European Communiqué
Some European chiropractic institutions issued a communiqué [3] at the 2015 scientific meeting conducted by the World Federation of Chiropractic in Athens. [4] The communiqué includes the statement:
The teaching of vertebral subluxation complex as a vitalistic construct that claims that it is the cause of disease is unsupported by evidence. Its inclusion in a modern chiropractic
curriculum in anything other than an historical context is therefore inappropriate and unnecessary. [3]
The implications of the position promulgated in their document deserve close scrutiny.
Historical Perspective
Any student of chiropractic history would appreciate that the concept of vertebral
subluxation did not originate with DD Palmer. The record could not be more clear when it
attributes the term to an English medical physician, Edward Harrison, who in his paper [5]
and also his medical text published in the 1820s [6] identified small irregularities in spinal
function as ‘subluxations.’ To his credit, Harrison also identified such subluxations as being
associated with various health disorders. It is fair to say that given the diagnostic
knowledge of the time the disorders were essentially observable changes in structural
spinal characteristics with some indication of functional changes in a whole body sense. It
is therefore an incorrect premise to argue that subluxation is a uniquely chiropractic
descriptor developed by Palmer. It is true to state Palmer took this knowledge and
developed it further into a paradigm of health care. [7]
It appears disingenuous to obfuscate this historical perspective and present only a
truncated history. When one asks ‘why’ one sees a number of American states divided in
their scope of chiropractic practice largely on the basis of either seeking practice rights
similar to medical practitioners or remaining aligned with Palmer’s major premise which
includes conservative health care without drugs or surgery. It is also observed a majority of
private practitioners of chiropractic and multiple chiropractic institutions retain this holistic
healing approach [8]; however, some European chiropractic institutions are focusing their
curriculum solely on musculoskeletal pain. [9, 10]
I note that 2 European chiropractic colleges were recently denied institutional and
programmatic accreditation by the European Council on Chiropractic Education (ECCE)
and oral reports as personal communications from key informants and report analysis
associate this denial with the fact each includes the philosophy of chiropractic in its
education programs which adhere to the major premise. It is also telling that the ECCE has
been censured to a degree [11] by the European authority that empowers it, the European
Association for Quality Assurance in Higher Education (ENQA).
One also notes that of the 6 chiropractic institutions that are signatories to the European
communiqué 1 is in South Africa and another in France and neither have more than a
minimal record of publication in the discipline field. Two of the remaining 4 appear to have
mixed identities as chiropractic educational institutions, as 1 (Denmark) seems to not
deliver a chiropractic qualification, rather it is a degree in biomechanics [12], and the other
(Switzerland) has relegated chiropractic to a sub-discipline of medicine. [13] The 2
remaining institutions, Anglo-European Chiropractic College [10] and the Welsh Institute of
Chiropractic [9] contribute to the literature base of the profession. There would appear to
be an argument that these institutions which have disavowed the fundamental premise of
the chiropractic profession could in fact be considered as not being representative of
typical chiropractic institutions. Should this be true then the significance of their
communiqué is in question.
The Straw Man Argument
An error embedded in the communiqué is the suggestion that chiropractors consider
vertebral subluxation as the cause of disease. This is a ‘straw man’ argument that
suggests a mis-truth has substance when there seems in fact no contemporary evidence
that chiropractors hold this view. The published literature is replete with evidence in the
form of case reports that relate correction of vertebral subluxation with observable
changes in the health status of humans [14–16] and other vertebrates [17] but it is very
difficult if not impossible to find any statement of claim that subluxation is causal. In terms
of Sackett's paper [1] that formalised the concept of evidence-based medicine equal
weight was put on the literature, practitioner experience and patient input. A case report is
a concise triangulation of these 3 elements.
Not All Evidence Has Integrity
Before undertaking an exploration of Sackett et al’s arguments for what is termed
‘evidence-based medicine’ [1] and what chiropractors may consider as evidence-based
practice (EBP) it is worth looking at some of the supposed evidence presented in the guise
of chiropractic research. One recent paper in particular [18] provides a classic example of
why critical reading is an essential skill to be taught to today's chiropractic students
notwithstanding that critical writing is a skill seemingly lacking among some pools of
academic chiropractors. That paper deserves analysis. It was published in Chiropractic
and Manual Therapies, which serves Australia and Europe [19] and does not seem to be
short on submissions; thus, it is legitimate to ask why a paper would be published in 2016
using data deemed a decade old.
The Graston® modality as described by the trial authors is a massage system using
several hand-held stainless steel instruments. The technique is erroneously represented
by the authors as typical chiropractic technique for the thoracic spine but is in fact only a
modality used by a small number of manual practitioners. It cannot be considered
representative of chiropractic. The paper uses the Oswestry scale which is specifically for
low back pain, yet it is employed in the study to record thoracic pain. These are
physiologically and anatomically different regions of the spine. The researchers state they
altered a word or 2 so ‘low back’ became ‘thoracic.’ One of the named researchers is
Editor-in-Chief of the journal in which the paper was published yet the authors declare they
have no competing interests. There is no statement of funding and the intervention was
delivered by students and not trained practitioners of the modality. The conclusion from an
attempted assessment of a modality of manual therapy is given with the inference
chiropractic as a discipline has no effect with treatment of the thoracic spine. Does this
paper present valid evidence for its conclusion there is little to no difference between
traditional adjustive approaches to the thoracic spine and the use of the Graston®
modality?
In many areas of journal publication there seems to be a never-ending flow of papers that
are withdrawn from publication after they have been critically examined and fraudulence
either proven or suspected. [20, 21] This raises the interesting question as to at what time
a published paper may be considered evidence with such reliability and solidity to impact
practice methods. Perhaps this uncertainty is why EBM has such a poor uptake in medical
practice. [22]
If medicine in general expresses reservations regarding an unquestioning uptake of EBP
perhaps it is somewhat unwise for academic chiropractors to wantonly embrace what
seems to be a flawed paradigm and in so doing alter the premise under which
chiropractic’s social conscience is expressed in community care. It is not just chiropractors
who should exhibit caution. A striking review by Tonelli found ‘Despite its promise, EBM
currently fails to provide an adequate account of optimal medical practice. A broader
understanding of medical knowledge and reasoning is necessary.’ [23] Others have
argued that EBM is in crisis [24] as while ‘originally described as a revolution in medicine
… Its renaissance will require changes in research and practice that are no less radical.’ [25] Experts propose ‘Orthodox medicine should consider abandoning demands that CAM
become evidence-based, at least as ‘‘evidence’’ is currently narrowly defined, but insist
instead upon a more complete and coherent description and defence of the alternative
epistemic methods and tools of these disciplines’ [26] and that EBM’s ‘pyramid of
possibilities’ should be revisited especially by third-party payers. [27] The question has to
be asked as to whether EBP has a significant role in contemporary chiropractic education.
Sackett [28] argues strongly for its importance in academic medicine.
Practice Paradigms
For many years aspects of chiropractic practice in the style of the major premise have
been strongly supported by evidence. I am an academic and not a Gonstead practitioner
yet it is obvious that any teaching of chiropractic technique must go beyond the basic
diversified moves and into a realm where considered opinion is given to found clinical
evidence. The Gonstead paradigm of practice appears to do this at a reasonably
sophisticated level. One may argue about small technicalities but the fact remains that
clinical evidence is gathered and weighted and then used to direct a specific spinal
intervention in the form of a targeted chiropractic adjustment.
Other aspects of chiropractic technique such as Activator MethodsTM and Chiropractic
BiophysicsTM follow a similar path of detailed collection of evidence to form a working
diagnosis and the direct resultant of therapeutic intervention. It speaks poorly of any
academic who fails to appreciate most chiropractors rely on some form of evidence on a
daily basis. Many chiropractors also use a clinical diagnostic approach known as Applied
Kinesiology (AK) to identify the optimal therapeutic target within the spine and other body
parts. There is no doubt AK is supported by extensive research-based evidence and it is
noted it is an approach also used by other health disciplines which practice in an evidence
based manner. [29, 30]
The Therapeutic Target
Many chiropractors refer to the target for intervention as subluxation [31] as do the
majority of chiropractic students. [32] It is unethical for a healthcare provider to impart a
therapy in the absence of a working diagnosis. In turn, this begs the question as to the
diagnostic language utilised by those who deny the use of the term subluxation. Rome has
published almost 300 synonyms drawn from the medical, chiropractic and healthcare
literature that are used in some way or another to label in the spine the therapeutic target
by a variety of manual-care providers. [33] A personal communication from Rome
suggests an updated list is in the process of being readied for publication and essentially
doubles the number of synonyms. A semiotic review of this plethora of terms demonstrates
subtle differences in meaning such as to render interchangeability difficult. For example
‘posterior joint dysfunction’ describes a very specific mechanical disorder within defined
structures of the spinal motion unit. It does not equate to subluxation. A ‘somatic lesion’
similarly refers to a specific lesion within a body part but fails to account how a chiropractic
adjustment impacts sensorimotor integration, for example. [34]
Therefore to what do those who deny subluxation direct their spinal therapy? Which
elements are selected to determine whether care delivered into socially-sensitive
communities is complete chiropractic care? If the student’s learning journey is not lead into
the proper use of the term ‘subluxation’ are they being compromised in the level of
chiropractic care they are able to offer? Similarly, if educators fail to use the term
‘adjustment’ with or without the descriptor ‘chiropractic’ is the delivery of such care
compromised? This type of prejudice would seem to be in ignorance of the chiropractic
dialect preferred by a large proportion (93.6%) of surveyed chiropractors. [35] It also
demonstrates ignorance of the technical aspects of the adjustment compared to
mobilization, which are very different elements within the manipulation spectrum with
different clinical effects. On the other hand there are academic chiropractors who are
actively researching and reporting on the force and time dimensions of the adjustment. [36] To refer to the chiropractic adjustment as manipulation is not only technically
incorrect, it is misleading. To exclude the terms adjustment and subluxation is also to
exclude neurological and brain research by authors in various fields, most notably Haavik.
Collectively, a denial of these elements of chiropractic’s major premise compromise the
level of care provided. Were chiropractic to fully step-up to deliver on its social conscience
of care for the less fortunate then it is reasonable to argue the original concepts and major
premise should remain the driving force.
The Subluxation Paradigm
A contemporary understanding of subluxation, a term within chiropractic’s major premise,
will show it is not appropriate to consider it as merely ‘an historical artefact.’ Not only are
there well-referenced texts on the topic written by noted authors [37–39] but also multiple
papers [40, 41] including my own. [42] Those who have studied the chiropractic
subluxation appreciate it is not a ‘thing’ nor is it correct to suggest it is simply a vitalistic
construct. If subluxation were a construct, it could be shown to exist through the
application of the Theory of Abstract Objects, a methodology used by Massimi to
demonstrate the presence of unobservable phenomena. [43] The minority-college
communiqué fails to acknowledge this. It may be useful to consider subluxation as a
conceptual framework to organise and rank found clinical evidence and to allow the
development and ranking of outcomes measures by clinical finding. It is incongruous to
proffer argument in favour of evidence-based practice and at the same time discard the
most valuable tool for gathering evidence to guide optimal therapeutic intervention.
When subluxation is used as a conceptual framework it is able to be deconstructed to 6
clinical subsets. Five of these were originally discussed by Lantz [44] and refined a
decade ago by others. These 5 subsets allow the documentation of clinical evidence of
spinal intersegmental kinematic change, muscle change, neurological change, connective
tissue change and vascular change. Manual detection of painful upper cervical joint
dysfunction is known to be excellent to complete. [45] Muscle change may be classified as
functional or structural change in both intrinsic, directly linked with the spinal motion unit,
and extrinsic muscles which are remote to the spinal motion unit and may reflect neural
change. Neural change itself may be categorised as Newtonian, such as pain and/or
dysesthesia, or Quantum, as in cognitive, affective or evaluative change. Connective
tissue change most commonly references the intervertebral disc but also includes all
ligaments, both intrinsic such as the anterior or posterior longitudinal ligaments of the
spine and extrinsic ligaments and tendons. It expands to include fascia and fascial planes
and trains. Vascular change includes systemic findings such as hypertension or
cerebrospinal fluid dynamics and localised suspicions such as intra-spinal venous stasis.
The 6th subset is emerging and perhaps requires the most scholarly enquiry. It relates to
visceral change, and is yet to become a widely recognised element of contemporary
chiropractic practice but could include infantile colic, for example.
At no stage do I suggest subluxation has a proven causal relationship with these clinical
changes; however, when clinical evidence is found, gathered and recorded in the subsets
described above it becomes inconceivable to deny the vertebral subluxation complex, or
simply the subluxation. From known findings a clinical impression may be formed and a
most-likely working diagnosis developed to guide specific therapeutic intervention,
commonly in the form of the chiropractic adjustment, either manual or mechanically
assisted. It is at this point that the adjustment is inexorably linked with subluxation. Further
the gathered clinical evidence auto-generates outcomes measurements that demonstrate
overt clinical change pre- and post-intervention.
To not teach subluxation in a contemporary context is to deny tomorrow's chiropractors
one of if not the most valuable tool to assist evidence-based clinical decision making.
Again it must be asked to what do subluxation deniers direct their therapeutic intervention?
Or are we seeing poor-quality clinicians deliberately ‘dumb down’ concepts they fail to
understand and thus refuse to use? In turn is this a fair representation of academic
chiropractic and is it a responsible approach within chiropractic education? The simple fact
is that when any academic is assigned topics to teach it is meant to reflect their high
degree of expertise in a specific field and not to provide a platform for the expression of
ignorance and misguided bias.
Managing Any Damage
Whether or not it was appropriate to use the cloak of a scientific meeting of integrity
conducted by the World Federation of Chiropractic (WFC) [4] to release the minority-college communiqué is a question for others. Is it possible for a few academic
chiropractors to have wrought damage to the profession globally by demeaning the major
premise of the profession, a premise that each naysayer bought into when they selected
chiropractic as a career? If damage has indeed been wrought it may be seen as having
multiple layers. The first is the selling out of students by short-changing them through the
removal of a way of critical clinical thinking that allows the construction and ranking of
evidence and its associated outcomes measurements. The second layer is personal
withdrawal from a professional identity that distinguishes chiropractic from physical
therapy, massage therapy and even osteopathy. It is tempting to propose that rather than
slash and burn a concept in which they decline to invest the time and energy to properly
understand it would be a lot simpler for chiropractic critics of chiropractic to change their
discipline. A third layer of damage lies in providing a schism for exploitation by those with a
vested interest in attacking the chiropractic profession. [46] The fourth layer and perhaps
the greatest indictment is that there is a regrettable lack among some academics of an
understanding of the nuances of evidence-based practice. One would reasonably demand
a higher level of collective wisdom from those entrusted with the professional training of
young minds. It is inappropriate for a minority of academic chiropractors to deliberately
create a null curriculum [47] where elements are knowingly and wilfully removed.
However, as signaled in the title of this commentary, perhaps the real benefits are
achieved by not diluting the powerful effects of chiropractic practice when practiced in
accord with its major premise, especially by educational institutions which fulfil societal
obligations to exhibit a social conscience by providing the best quality of care to those who
may not be able to afford it nor have ready access to it.
CONCLUSION
One can only hope that any future communiqués are themselves evidence-based. The
behaviour of some is certainly a blight on the social conscience of chiropractic by
damaging the major premise of the profession and severely reducing the integrity of the
learning journey for students and the quality of care provided to those with genuine need.
One can only hope such attitudes do not gain traction in current and future practitioners.
