Studies
"...spinal manipulation applied by chiropractors is shown
to be more effective than alternative treatment for low-back pain"– The
Magna Study
The effectiveness of chiropractic has been repeatedly documented in studies
from such groups as the AHCPR (Agency for Health Care Policy and Research;1994),
Ontario Ministry of health (Magna;1993), Rand Corporation amongst others.
It is widely accepted by insurance companies.
- U.S. GOVERNMENT AGENCY REPORT
A study published by the U.S.
AHCPR and the U.S. department of Health and Human Services endorses spinal
manipulation for acute low back pain in adults in its Clinical Practice
Guideline #14. An independent multidisciplinary panel of private-sector
clinicians and other experts convinced and developed specific statements on
appropriate health care of acute low back problems in adults. One
statement cited, relief of discomfort (low back pain) can be accomplished most
safely with spinal manipulation, and/or nonprescription
medication.
- THE MAGNA REPORT
A major study to assess the most appropriate
use of available health care resources was reported in 1993. This was an
outcomes study funded by the Ontario Ministry of Health and conducted in hopes
of sharing information about ways to address cost-effective ways to
rehabilitate disabled and injured workers. The study was conducted by
three health economists led by University of Ottawa Professor Pran Magna,
Ph.D. The report of the study is commonly called the Magna Report.
The Magna Report overwhelmingly supported the efficacy, safety, scientific validity, and
cost-effectiveness of chiropractic for low-back pain. Additionally, it
found that higher patient satisfaction levels were associated with
chiropractic care than with medical treatment alternatives. "Evidence
from Canada and other countries suggests potential savings of hundreds of
millions annually," the Magna Reports states. "The literature clearly
and consistently shows that the major savings from chiropractic management
come from fewer and lower costs of auxiliary services, fewer and lower costs
of auxiliary services, fewer hospitalizations, and a highly significant
reduction in chronic problems, as well as in levels and duration of
disability."
- RAND STUDY ON LOW-BACK PAIN
A four-phase conducted in
the early 1990's by RAND, one of America's most prestigious centers for
research in public policy, science and technology, explored many indications
of low-back pain. In the RAND studies, an expert panel of researchers, including medical
doctors of chiropractic, found that:
- chiropractors deliver a substantial amount of health care of the U.S. population.
- spinal manipulation is of benefit to some patients with acute low-back pain.
The
RAND reports marked the first time that representatives of the medical
community went on record stating that spinal manipulation is an appropriate
treatment for certain low-back pain conditions.
- WASHINGTON HMO STUDY
In
1989, a survey administered by Daniel C. Cherkin, Ph.D., and
Frederick A. MacCornack, Ph.D., concluded that patients receiving care from
health maintenance organization (HMOs) within the state of Washington were
three times as likely to report satisfaction with care from chiropractors as
they were also more likely to believe that their chiropractor was concerned
about them.
- STANO COST COMPARISON STUDY
A study
by Miron Stano, Ph.D., reported in
the June 1993 Journal of Manipulative and physiological Therapeutics involved
395,641 patients with neuromusculoskeletal conditions. Results over a
two-year period showed that patients who received chiropractic care incurred
significantly lower health care costs that did patients treated solely by
medical or osteopathic physicians.
- SAKATCHEWAN CLINICAL RESEARCH
Following a 1993 study,
researchers J. David Cassidy, D.C., M.S., and W. Kirkaldy-Willis, M.D., of the
Back Pain Clinic at the Royal University Hospital in Saskatchewan concluded
that "the treatment of lumbar intervertebral disk herniation by side posture
manipulation is both safe and effective."
- WIGHT STUDY ON RECURRING HEADACHES
A 1978 study conducted by J.S. Wight,
D.C., and reported in the ACA Journal of Chiropractic, indicated that 74.6% of
patients with recurring headaches, including migraines, were either cured or
experienced reduced headache symptomatology after receiving chiropractic
manipulation.
- 1990 BRITISH MEDICAL JOURNAL REPORT
A study conducted by T.W.
Meade, a medical doctor, and reported in the June 2, 1990, British Medical
journal concluded after two years of patient monitoring, "for patients with
low-back pain in whom manipulation is not contraindicated, chiropractic almost
certainly confers worthwhile, long-term benefit in comparison with hospital
outpatient management.
- VIRGINIA COMPARATIVE STUDY
A 1992 study conducted
by L.G. Schifrin, Ph.D., provided an economic assessment of mandated health
insurance coverage for chiropractic treatment within the Common- wealth
of Virginia. As reported by the College of William and Mary, and the
Medical College of Virginia, the study indicated that chiropractic provides
therapeutic benefits at economical costs. The report also recommended
that chiropractic be a widely available form of health care.
- 1992 UNIVERSITY OF SASKATCHEWAN STUDY
In 1985 the University of
Sakatchewan conducted a study of 283 patients "who had not responded to
previous conservative or operative treatment" and who were initially
classified as totally disabled. The study revealed that"81%...became
symptom free or achieved a state of mild intermittent pain who no work
restrictions" after daily spinal manipulations were
administered.
- LANDMARK LEGAL DECISION SUPPORTS CHIROPRACTIC
Further validation of
chiropractic care evolved from an antitrust suit which was filed by four
members of the chiropractic profession against the American Medical
Association (AMA) and a number of other health care organizations in the U.S.
(Wilk et al v. AMA et al, 1990). Following 11 years of
litigation, a federal appellate court judge upheld a ruling by U.S. District
Court Judge Susan Getzendanner that the AMA had engaged in a "lengthy,
systematic, successful and unlawful boycott" designed to restrict cooperation
between MDs and chiropractors in order to eliminate the profession of
chiropractic as a competitor in the U.S. health care system.
Judge Getzendanner rejected the AMA's patient care defense, and cited
scientific studies which implied that "chiropractic care was twice as
effective as medical care in relieving many painful conditions of the neck and
back as well as related musculo-skeletal problems." Since the court's
findings and conclusions were released, an increasing number of medical
doctors, hospitals and health care organizations in the U.S. have begun to
include the services of chiropractors.
