Vertebral Subluxation - Definitions and Current Official Status

Definitions and Current Official Status

The WHO definition of the chiropractic vertebral subluxation is:

"A lesion or dysfunction in a joint or motion segment in which alignment, movement integrity and/or physiological function are altered, although contact between joint surfaces remains intact. It is essentially a functional entity, which may influence biomechanical and neural integrity."

The purported displacement is not necessarily visible on X-rays. This is in contrast to the medical definition of spinal subluxation which, according to the WHO, is a "significant structural displacement", and therefore visible on X-rays.

In 1996 an official consensus definition of subluxation was formed. Cooperstein and Gleberzon have described the situation: "... although many in the chiropractic profession reject the concept of "subluxation" and shun the use of this term as a diagnosis, the presidents of at least a dozen chiropractic colleges of the Association of Chiropractic Colleges (ACC) developed a consensus definition of "subluxation" in 1996. It reads:

"Chiropractic is concerned with the preservation and restoration of health, and focuses particular attention on the subluxation. A subluxation is a complex of functional and/or structural and/or pathological articular changes that compromise neural integrity and may influence organ system function and general health. A subluxation is evaluated, diagnosed, and managed through the use of chiropractic procedures based on the best available rational and empirical evidence."

In 2001 the World Federation of Chiropractic, representing the national chiropractic associations in 77 countries, adopted this consensus statement which reaffirms belief in the vertebral subluxation.

The ACC paradigm has been criticized by chiropractic authors:

"All in all, the ambiguities that permeate the ACC's statements on subluxation render it inadequate as a guide to clinical research... Whether the ACC's subluxation claims have succeeded as a political statement is beyond our concern here. These assertions were published as a priori truths (what many chiropractors have traditionally referred to as "principle"), and are exemplary of scientifically unjustified assertions made in many corners of the profession. It matters not whether unsubstantiated assertions are offered for clinical, political, scientific, educational, marketing or other purposes; when offered without acknowledgment of their tentative character, they amount to dogmatism. We contend that attempts to foster unity (among the schools or in the wider profession) at the expense of scientific integrity is ultimately self-defeating. To be sure, the profession's lack of cultural authority is based in part upon our characteristic disunity. However, attempts to generate unity by adoption of a common dogma can only bring scorn and continued alienation from the wider health care community and the public we all serve."

In May 2010 the General Chiropractic Council, the statutory regulatory body for chiropractors in the United Kingdom, issued guidance for chiropractors stating that the chiropractic vertebral subluxation complex "is an historical concept" and "is not supported by any clinical research evidence that would allow claims to be made that it is the cause of disease or health concerns."

    Lord Byron is an exceedingly interesting person, and as such is it not to be regretted that he is a slave to the vilest and most vulgar prejudices, and as mad as the winds?
    There have been many definitions of beauty in art. What is it? Beauty is what the untrained eyes consider abominable.
    Edmond De Goncourt (1822–1896)

    A reaction: a boat which is going against the current but which does not prevent the river from flowing on.
    Victor Hugo (1802–1885)

    I thought it altogether proper that I should take a brief furlough from official duties at Washington to mingle with you here to-day as a comrade, because every President of the United States must realize that the strength of the Government, its defence in war, the army that is to muster under its banner when our Nation is assailed, is to be found here in the masses of our people.
    Benjamin Harrison (1833–1901)

    Anthropologists have found that around the world whatever is considered “men’s work” is almost universally given higher status than “women’s work.” If in one culture it is men who build houses and women who make baskets, then that culture will see house-building as more important. In another culture, perhaps right next door, the reverse may be true, and basket- weaving will have higher social status than house-building.
