Chiropractic Research Doctor's of
chiropractic have long been dedicated to delivering the safest and most
effective healing methods for their patients. To achieve this, the
chiropractic profession has been dedicated to scientific evaluation of
their diagnostic and treatment methods and techniques.
Chiropractic health care has an impressive array of studies which
support and prove the effectiveness of chiropractic care in a variety
of different health ailments and many more studies are currently
underway. Many of these studies have been performed not only by
chiropractors, but by other health care professionals and federal
government studies of various countries.
The chiropractic profession has actually accumulated a greater number
of scientific trials than the medical profession has for many of the
more common treatments rendered by medical doctors. According to David
M. Edy, M.D., Ph.D., professor of health policy and management with
Duke University, North Carolina, only 15 percent of all medical
interventions are supported by solid scientific evidence. Paul G.
Shekelle, M.D., MPH, of the RAND Corporation made the following
statement on ABC's 20/20,
"There are considerably more randomized controlled trials which show
benefit of this (chiropractic) than there are for many, many other
things which physicians and neurosurgeons do all the time."

Government Studies on Chiropractic There
have been a number of large investigations conducted on chiropractic by
the American, Canadian, New Zealand, Swedish and Australian governments
over the last few decades. In all cases, their findings have supported
the effectiveness and efficacy of Chiropractic.
Canada's 1993 Manga Report strongly recommended chiropractic care over
medical care for the treatment and management of most low-back
conditions. The 1994 AHCPR Study from the U.S. Department of Health and
Human Services suggested that chiropractic spinal manipulation was a
conservative and safe treatment for many low-back conditions and should
be utilized prior to any surgical interventions in most cases.
Doctors of Chiropractic have now become integral to the development of
governmental guidelines for the treatment of back conditions in Canada
and the U.S. In addition, many hospitals are extending privileges to
chiropractors and referrals between medical doctors and chiropractors
are becoming increasingly common.

THE AGENCY ON HEALTH CARE POLICY AND RESEARCH STUDY
On December 8, 1994, the Agency for Health Care Policy and Research
(AHCPR) of the US Department of Health and Human Services released
Clinical Practice Guidelines for the management of acute low back pain.
Their guidelines were developed after extensive study of diagnostic and
treatment methods for acute low back pain.
The guidelines were created by the AHCPR panel to provide primary care
clinicians with information and recommended strategies for the
assessment and treatment of acute low back problems. The AHCPR panel
was made up of 23 members consisting of medical doctors, chiropractic
doctors, nurses, experts in spinal research, physical therapists, an
occupational therapist, a psychologist, and a consumer representative.
The following conclusions were made in this landmark study:
Conservative treatment such as spinal manipulation should be pursued in most before cases considering surgical intervention;
Prescription drugs such as oral steroids, antidepressant medications
and colchicine are not recommended for acute low back problems.
Other interesting finds included:
The risk of serious complications from lumbar spinal manipulation is rare;
There is currently no evidence supporting the use of trigger point,
ligamentous and facet injections, needle acupuncture or dry needling as
treatment for acute back problems;
The panel found no evidence of benefit from the application of physical
agents and modalities such as ice, heat, massage, traction, ultrasound,
cutaneous laser treatment, transcutaneous electrical nerve stimulation
(T.E.N.S.) and biofeedback techniques.

THE MANGA REPORT
As the largest existing analysis of scientific literature on low back
pain, the 1993 Ontario Ministry of Health commissioned study drew
international attention when it recommended the management of low back
pain be moved from medical doctors to chiropractic doctors.
Due to serious financial problems with the Canadian governments, the
different types of treatments for low back conditions were evaluated in
an effort to reduce and contain health care costs. Their findings
showed chiropractic manipulation was the most cost effective and
efficacious care for low back pain.
The researchers also stated that studies on the prevalence and
incidence of low back pain suggest that it is the leading cause of
disability and morbidity in middle-aged persons, and is by far the most
expensive source of workers' compensation costs North America.
The Canadian Government report concluded with the following findings:
On the evidence, particularly the most scientifically valid clinical
studies, spinal manipulation applied by chiropractors is shown to be
more effective than alternative treatments for low back pain. Many
medical therapies are of questionable validity or are clearly
inadequate;
There is no clinical or case-control study that demonstrates or even
implies that chiropractic spinal manipulation is unsafe in the
treatment of low back pain. Some medical treatments are equally safe,
but others are unsafe and generate iatrogenic (doctor-induced)
complications for low back pain patients. Our reading of the literature
suggests that chiropractic manipulation is safer than medical
management of low back pain;
Indeed, several existing medical therapies of low back pain are
generally contraindicated on the basis of the existing clinical trials.
There is also some evidence in the literature to suggest that spinal
manipulations are less safe and less effective when performed by
nonchiropractic professionals;
There is an overwhelming body of evidence indicating that chiropractic
management of low back pain is more cost-effective than medical
management;
There would be highly significant cost savings if more management of
low back pain was transferred from physicians to chiropractors.
Evidence from Canada and other countries suggests potential savings of
many hundreds of millions annually;
Workers' compensation studies report that injured workers with the same
specific diagnosis of low back pain returned to work much sooner when
treated by chiropractors than by medical physicians;
There is good empirical evidence that patients are very satisfied with
chiropractic management of low back pain and considerably less
satisfied with medical physician management;
The use of chiropractic has grown steadily over the years and
chiropractors are now accepted as a legitimate healing profession by
the public and an increasing number of medical physicians;
In our view, the following offers an overwhelming case in favor of much
greater use of chiropractic services in the management of low back
pain:
the effectiveness and cost effectiveness of chiropractic management of low back pain
the untested, questionable or harmful nature of many current medical therapies
the economic efficiency of chiropractic care for low back pain compared with medical care
the safety of chiropractic care
the higher satisfaction levels expressed by patients of chiropractors.
The following recommendations were also included in the report:
There should be a shift in policy to encourage and prefer chiropractic services for most patients with low back pain;
Chiropractic services should be fully insured under the Ontario Health Insurance Plan;
Chiropractic services should be fully integrated into the health care system;
Chiropractors should be employed by tertiary hospitals in Ontario;
Hospital privileges should be extended to all chiropractors for the
purposes of treatment of their own patients who have been hospitalized
for other reasons, and for access to diagnostic facilities relevant to
their scope of practice and patients' needs;
Chiropractic should have access to all pertinent patient records and
tests from hospitals, physicians, and other health care professionals
upon the consent of their patients;
Since low back pain is of such significant concern to workers'
compensation, chiropractors should be engaged at a senior level by
Workers' Compensation Board to assess policy, procedures and treatment
of workers with low back injuries;
A very good case can be made for making chiropractors the gatekeepers
for management of low back pain in the workers' compensation system in
Ontario;
The government should make the requisite research funds and resources
available for further clinical evaluations of chiropractic management
of low back pain, and for further socioeconomic and policy research
concerning the management of low back pain generally;
Chiropractic education in Ontario should be in the multidisciplinary
atmosphere of a university with appropriate public finding;
Finally, the government should take all reasonable steps to actively
encourage cooperation between providers, particularly the chiropractic,
medical and physiotherapy professions.

THE NEW ZEALAND COMMISSION REPORT
This 377 page report, Chiropractic In New Zealand, was the most
comprehensive and detailed independent examination of chiropractic ever
undertaken at that time. The report withstood judicial hearings and
extensive investigations by the Commission in New Zealand, the United
States, Canada, England and Australia.
According to the researchers,
"We entered into our inquiry in early 1978. We had no clear idea what
might emerge. We knew little about chiropractors. None of us had
undergone any personal experience of chiropractic treatment. If we had
any general impression of chiropractic it was probably that shared by
many in the community: that chiropractic was an unscientific cult, not
to be compared with orthodox medical or paramedical services. We might
well have thought that chiropractors were people with perhaps a strong
urge for healing, who had for some reason not been able to get into a
field recognized by orthodox medicine and who had found an outlet
outside the fringes of orthodoxy."
"But as we prepared ourselves for this inquiry it became apparent that
much lay beneath the surface of these apparently simple terms of
reference. In the first place it transpired that for many years
chiropractors had been making strenuous efforts to gain recognition and
acceptance as members of the established health care team. Secondly, it
was clear that organized medicine in New Zealand was adamantly opposed
to this on a variety of grounds which appeared logical and responsible.
Thirdly, however, it became only too plain that the argument had been
going on ever since chiropractic was developed as an individual
discipline in the late 1800's, and that in the years between then and
now the debate had generated considerable more heat than light."
"By the end of the inquiry we found ourselves irresistibly and with
complete unanimity drawn to the conclusion that modern chiropractic is
a soundly based and valuable branch of the health care in a specialized
area..."
Their report includes the following findings:
Chiropractic is a branch of the healing arts specializing in the
correction by spinal manual therapy of what chiropractors identify as
biomechanical disorders of the spinal column - they carry out spinal
diagnosis and therapy at a sophisticated and refined level;
Chiropractors are the only health practitioners who are necessarily
equipped by their education and training to carry out spinal manual
therapy;
General medical practitioners and physiotherapists have no adequate training in spinal manual therapy;
Spinal manual therapy in the hands of a registered chiropractor is safe;
The education and training of a registered chiropractor are sufficient
to enable him/her to determine whether there are contraindications to
spinal manual therapy in a particular case, and whether the patient
should have medical care instead of or as well as chiropractic care;
Spinal manual therapy can be effective in relieving musculoskeletal
symptoms, such as back pain and other symptoms known to respond to such
therapy, such as migraine;
In a limited number of cases where there are organic and/or visceral
symptoms, chiropractic treatment may provide relief, but this is
unpredictable, and in such cases the patient should be under concurrent
medical care if that is practicable;
In the public interest and in the interests of patients, there must be
no impediment to full professional cooperation between chiropractors
and medical practitioners;
It is wrong that the present law, or any medical ethical rules, should
have the effect that a patient can receive spinal manual therapy which
is subsidized by a health benefit only from those health professionals
least qualified to deliver it;
The responsibility for spinal manual therapy training, because of its
specialized nature, should lie with the chiropractic profession and
part-time or vacation courses in spinal manual therapy for other health
professionals should not be encouraged.

THE SWEDEN REPORT
Up until the late 1980's, Sweden had no legislation regulating the
practice of chiropractic, although there were approximately 100
chiropractors in Sweden educated in accredited chiropractic colleges.
In 1987, a commission on Alternative Medicine in Sweden conducted a
detailed investigation of chiropractic education. They had the
scientific literature assessed by university medical faculty and
additionally commissioned a demographic survey by Statistics Sweden.
Subsequent to the report, the Swedish government passed legislation
recognizing and regulating the chiropractic profession in Sweden. Then,
together with the governments from Denmark, Finland and Norway, it
established a school of chiropractic at the University of Odense in
Denmark to provide a regional chiropractic college for students from
those countries.
The reports findings included:
Doctors of chiropractic should become registered practitioners and be brought within the national insurance system in Sweden;
Training for Doctors of Chiropractic follows a 4-5 year course of
university level training and was found to be the equivalent to Swedish
medical training - chiropractors have "competence in differential
diagnosis" and should be regulated on a primary care basis";
"Measures to improve cooperation between chiropractors, registered
medical practitioners and physiotherapists are vital" in the public
interest.

THE AUSTRALIAN REPORT
In July of 1984 the Australian Federal Minister for Health asked their
Medicare Benefits Review Committee to "consider requests for extending
the scope of Medicare (government-funded health care) arrangements to
provide benefits for certain paramedical services" - which included
chiropractic services.
The Committee recommended funding for chiropractic in hospitals and other public institutions, and stated:
"We are aware of the very considerable organizational and professional
obstacles... orthodox practitioners and, indeed, some chiropractors may
initially find the experience an uneasy one, but we consider the
differences that currently exist to be unreasonable and efforts should
be made to bridge the gap."
"... the continuing schism between the two professions does little to
help improve the health of the many Australians who might benefit from
a joint chiropractic/medical approach to their problems."
