While the ongms of spinal manipulation date back to ancient times, it
was curtailed during the Dark Ages in Europe due to superstition.
During the Middle Ages, spinal manipulation resurfaced and enjoyed
popularity under the name bone-setting.
Modern chiropractic owes its establishment as an alternative healing
practice to Daniel David Palmer (1845-1913), a former magnetic healer
who concluded that misaligned vertebrae were the principal cause of
According to most recountings, Palmer thought he cured a janitor of
deafness by putting a misaligned vertebrae back into position. He
opened the first school of chiropractic in Davenport, Iowa, in 1897.
Chiropractic's underlying premise is that the vertebrae frequently
become misaligned due to injury, stress, and poor posture. These are
called "subluxations." According to chiropractic, when nerve
transmission to a particular organ or part of the body is impaired, it
causes dysfunction, pain and illness.
In practice, there are two main philosophies "straight" and "mixers."
The former is narrow in scope, dealing only with spinal adjustments.
The latter utilises a variety of adjunctive therapies, vitamin therapy
and nutritional counselling. Physical manipulation is employed to
Few if any "alternative" practices have provoked as much criticism from
medical practitioners as chiropractic — and not without good reason.
The basic tenet of chiropractic is the vertebral subluxation defined
creating pressure on nerve tissue, and thus interfering with the
conduction of nerve impulses to other parts of the body".
In vitalistic theory it is claimed that spinal "subluxations"
mechanically interfere with nerve flow, weakening organs served by the
nerves and making them more susceptible to disease ... thus,
"subluxations" are the primary "cause" of the disease and restoration
of nerve flow is essential to healing.
The physiological fact is however, that if there is a partial blockage
of impulses in a nerve fibre ... although the impulse is transmitted
more slowly, it resumes all its characteristics as soon as it reaches
normal tissue. Thus it is impossible for a partial blockage of nerve
impulses in a particular zone to affect the flow. Furthermore,
experiments by anatomists on the spinal column have shown that any
suggestion of a connection between spinal nerves, specific body regions
and organs is erroneous. (Cretin 1973).
Edmund S. Crelin, Ph.D., a prominent anatomist from Yale University,
tested the "subluxation" theory by studying the spines of three adults
and three children within a few hours of their deaths. While twisting
each spine with a drill press, he observed the spinal nerves and the
openings through which they passed. Even with a greater force than
could occur in a living person, no nerve compression took place.
Chiropractic theory has failed tests of both validity and reliability.
The "subluxation" foundation on which its tenets rest has never been
demonstrated to exist. Even Palmer's original claim to have cured
deafness by manipulation suggests that he was not aware that the nerve
which conveys sound information from the ears to the brain does not
pass through the neck.
"Modern" chiropractors define "subluxations" in other ways, many of
which involve "fixation" or restriction of spinal joint motion.
However, the vast majority of chiropractors still exaggerate the
significance of the spine and its relationship to health.
The risks associated with forceful neck manipulations include the
possibility of stroke and paralysis. A survey by the Stanford
(University) Stroke Center (Lee c
1995), found that within a two year period, fifty-six strokes had
occurred among patients within twenty-four hours after receiving neck
manipulation by a chiropractor.
In 1963, the College of Physicians and Surgeons of the Province of
Quebec submitted a brief to the Royal Commission on Chiropractic, which
was appointed by the Quebec legislature to study the chiropractic
question. The brief was prepared by the college in an effort to
persuade the Royal Commission that the licencing of chiropractors in
Quebec was not in the best interests of the public health.’’
In part, the brief examined the existence or absence of scientific data
in support of basic chiropractic theories and the findings were
presented in an objective and scientific manner. In its summary, the
brief concluded that chiropractic is a false theory and that it is
potentially dangerous. Since 1973, when the American Congress included
chiropractic under Medicare, hundreds of millions of dollars have been
paid out for treatment by something that doesn’t exist.
