Although a wide diversity of ideas exist among chiropractors,[34] they share the belief that the spine and health are related in a fundamental way, and that this relationship is mediated through the nervous system.[37] Some chiropractors claim spinal manipulation can have an effect on a variety of ailments such as irritable bowel syndrome and asthma.[38]
Chiropractic philosophy includes the following perspectives:[35]
Holism assumes that health is affected by everything in an individual's environment; some sources also include a spiritual or existential dimension.[39] In contrast, reductionism in chiropractic reduces causes and cures of health problems to a single factor, vertebral subluxation.[36] Homeostasis emphasizes the body's inherent self-healing abilities. Chiropractic's early notion of innate intelligence can be thought of as a metaphor for homeostasis.[34]
A large number of chiropractors fear that if they do not separate themselves from the traditional

Straight chiropractors adhere to the philosophical principles set forth by D. D. and B. J. Palmer, and retain metaphysical definitions and vitalistic qualities.[42] Straight chiropractors believe that vertebral subluxation leads to interference with an "innate intelligence" exerted via the human nervous system and is a primary underlying risk factor for many diseases.[42] Straights view the medical diagnosis of patient complaints, which they consider to be the "secondary effects" of subluxations, to be unnecessary for chiropractic treatment.[42] Thus, straight chiropractors are concerned primarily with the detection and correction of vertebral subluxation via adjustment and do not "mix" other types of therapies into their practice style.[42] Their philosophy and explanations are metaphysical in nature and they prefer to use traditional chiropractic lexicon terminology such as "perform spinal analysis", "detect subluxation", "correct with adjustment".[21] They prefer to remain separate and distinct from mainstream health care.[21] Although considered the minority group, "they have been able to transform their status as purists and heirs of the lineage into influence dramatically out of proportion to their numbers."[21]
Mixer chiropractors "mix" diagnostic and treatment approaches from chiropractic, medical or osteopathic viewpoints and make up the majority of chiropractors.
Although mixers are the majority group, many of them retain belief in vertebral subluxation as shown in a 2003 survey of 1,100 North American chiropractors, which found that 88 percent wanted to retain the term "vertebral subluxation complex", and that when asked to estimate the percent of disorders of internal organs that subluxation significantly contributes to, the mean response was 62 percent.
Vertebral subluxation
In science-based medicine, the term "subluxation" refers to an incomplete or partial
Palmer claimed that vertebral subluxations interfered with the body's function and its inborn ability to heal itself.[49] D. D. Palmer repudiated his earlier theory that vertebral subluxations caused pinched nerves in the intervertebral spaces in favor of subluxations causing altered nerve vibration, either too tense or too slack, affecting the tone (health) of the end organ.[48] He qualified this by noting that knowledge of innate intelligence was not essential to the competent practice of chiropractic.[48] This concept was later expanded upon by his son, B. J. Palmer, and was instrumental in providing the legal basis of differentiating chiropractic from conventional medicine. In 1910, D. D. Palmer theorized that the nervous system controlled health:
Physiologists divide nerve-fibers, which form the nerves, into two classes, afferent and efferent. Impressions are made on the peripheral afferent fiber-endings; these create sensations that are transmitted to the center of the nervous system. Efferent nerve-fibers carry impulses out from the center to their endings. Most of these go to muscles and are therefore called motor impulses; some are secretory and enter glands; a portion are inhibitory, their function being to restrain secretion. Thus, nerves carry impulses outward and sensations inward. The activity of these nerves, or rather their fibers, may become excited or allayed by impingement, the result being a modification of functionality – too much or not enough action – which is disease.[50]
Vertebral subluxation, a core concept of traditional chiropractic, remains unsubstantiated and largely untested, and a debate about whether to keep it in the chiropractic paradigm has been ongoing for decades.
In 2005, the
As of 2014, the US National Board of Chiropractic Examiners states "The specific focus of chiropractic practice is known as the chiropractic subluxation or joint dysfunction. A subluxation is a health concern that manifests in the skeletal joints, and, through complex anatomical and physiological relationships, affects the nervous system and may lead to reduced function, disability or illness."[60][27]
Pseudoscience versus spinal manipulation therapy
While some chiropractors limit their practice to short-term treatment of musculoskeletal conditions, many falsely claim to be able treat a myriad of other conditions.[61][62] Some dissuade patients from seeking medical care, others have pretended to be qualified to act as a family doctor.[61]
Quackwatch, an alternative medicine watchdog, cautions against seeing chiropractors who:[61][63]
- Treat young children
- Discourage immunization
- Pretend to be a family doctor
- Take full spine X-rays
- Promote unproven dietary supplements
- Are antagonistic to scientific medicine
- Claim to treat non-musculoskeletal problems
Writing for the Skeptical Inquirer, one physician cautioned against seeing even chiropractors who solely claim to treat musculoskeletal conditions:
I think Spinal Manipulation Therapy (SMT) is a reasonable option for patients to try ... But I could not in good conscience refer a patient to a chiropractor... When chiropractic is effective, what is effective is not 'chiropractic': it is SMT. SMT is also offered by physical therapists, DOs, and others. These are science-based providers ... If I thought a patient might benefit from manipulation, I would rather refer him or her to a science-based provider.[61]
Scope of practice
Chiropractors emphasize the conservative management of the neuromusculoskeletal system without the use of medicines or surgery,[54] with special emphasis on the spine.[2] Back and neck pain are the specialties of chiropractic but many chiropractors treat ailments other than musculoskeletal issues.[8] There is a range of opinions among chiropractors: some believed that treatment should be confined to the spine, or back and neck pain; others disagreed.[64] For example, while one 2009 survey of American chiropractors had found that 73% classified themselves as "back pain/musculoskeletal specialists", the label "back and neck pain specialists" was regarded by 47% of them as a least desirable description in a 2005 international survey.[64] Chiropractic combines aspects from mainstream and alternative medicine, and there is no agreement about how to define the profession: although chiropractors have many attributes of primary care providers, chiropractic has more attributes of a medical specialty like dentistry or podiatry.[65] It has been proposed that chiropractors specialize in nonsurgical spine care, instead of attempting to also treat other problems,[36][65] but the more expansive view of chiropractic is still widespread.[66]
Mainstream health care and governmental organizations such as the World Health Organization consider chiropractic to be complementary and alternative medicine (CAM);[1] and a 2008 study reported that 31% of surveyed chiropractors categorized chiropractic as CAM, 27% as integrated medicine, and 12% as mainstream medicine.[67] Many chiropractors believe they are primary care providers,[8][9] including US[68] and UK chiropractors,[69] but the length, breadth, and depth of chiropractic clinical training do not support the requirements to be considered primary care providers,[2] so their role on primary care is limited and disputed.[2][9]
Chiropractic overlaps with several other forms of manual therapy, including massage therapy,
Chiropractic diagnosis may involve a range of methods including skeletal imaging, observational and tactile assessments, and orthopedic and neurological evaluation.[54] A chiropractor may also refer a patient to an appropriate specialist, or co-manage with another health care provider.[65] Common patient management involves spinal manipulation (SM) and other manual therapies to the joints and soft tissues, rehabilitative exercises, health promotion, electrical modalities, complementary procedures, and lifestyle advice.[5]
Chiropractors are not normally licensed to write medical prescriptions or perform major surgery in the United States[73] (although New Mexico has become the first US state to allow "advanced practice" trained chiropractors to prescribe certain medications[74][75]). In the US, their scope of practice varies by state, based on inconsistent views of chiropractic care: some states, such as Iowa, broadly allow treatment of "human ailments"; some, such as Delaware, use vague concepts such as "transition of nerve energy" to define scope of practice; others, such as New Jersey, specify a severely narrowed scope.[76] US states also differ over whether chiropractors may conduct laboratory tests or diagnostic procedures, dispense dietary supplements, or use other therapies such as homeopathy and acupuncture; in Oregon they can become certified to perform minor surgery and to deliver children via natural childbirth.[73] A 2003 survey of North American chiropractors found that a slight majority favored allowing them to write prescriptions for over-the-counter drugs.[43] A 2010 survey found that 72% of Swiss chiropractors considered their ability to prescribe nonprescription medication as an advantage for chiropractic treatment.[77]
A related field, veterinary chiropractic, applies manual therapies to animals and is recognized in many US states,[78] but is not recognized by the American Chiropractic Association as being chiropractic.[79] It remains controversial within certain segments of the veterinary and chiropractic professions.[80]
No single profession "owns" spinal manipulation and there is little consensus as to which profession should administer SM, raising concerns by chiropractors that other medical physicians could "steal" SM procedures from chiropractors.[81] A focus on evidence-based SM research has also raised concerns that the resulting practice guidelines could limit the scope of chiropractic practice to treating backs and necks.[81] Two US states (Washington and Arkansas) prohibit physical therapists from performing SM,[82] some states allow them to do it only if they have completed advanced training in SM, and some states allow only chiropractors to perform SM, or only chiropractors and physicians. Bills to further prohibit non-chiropractors from performing SM are regularly introduced into state legislatures and are opposed by physical therapist organizations.[83]
Treatments
Spinal manipulation, which chiropractors call "spinal adjustment" or "chiropractic adjustment", is the most common treatment used in chiropractic care.
There are several schools of chiropractic adjustive techniques, although most chiropractors mix techniques from several schools. The following adjustive procedures were received by more than 10% of patients of licensed US chiropractors in a 2003 survey:
Many other procedures are used by chiropractors for treating the spine, other joints and tissues, and general health issues. The following procedures were received by more than one-third of patients of licensed US chiropractors in a 2003 survey: Diversified technique (full-spine manipulation; mentioned in previous paragraph),
A 2010 study describing Belgian chiropractors and their patients found chiropractors in Belgium mostly focus on neuromusculoskeletal complaints in adult patients, with emphasis on the spine.[94] The diversified technique is the most often applied technique at 93%, followed by the Activator mechanical-assisted technique at 41%.[94] A 2009 study assessing chiropractic students giving or receiving spinal manipulations while attending a United States chiropractic college found Diversified, Gonstead, and upper cervical manipulations are frequently used methods.[95]
Practice guidelines
Reviews of research studies within the chiropractic community have been used to generate practice guidelines outlining standards that specify which chiropractic treatments are legitimate (i.e. supported by evidence) and conceivably reimbursable under
Effectiveness
Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with varied results.[8] There is no conclusive evidence that chiropractic manipulative treatment is effective for the treatment of any medical condition, except perhaps for certain kinds of back pain.[8][10]
Generally, the research carried out into the effectiveness of chiropractic has been of poor quality.[101][102] Research published by chiropractors is distinctly biased: reviews of SM for back pain tended to find positive conclusions when authored by chiropractors, while reviews by mainstream authors did not.[8]
There is a wide range of ways to measure treatment outcomes.
Available evidence covers the following conditions:
- Cochrane review found very low to moderate evidence that SMT was no more effective than inert interventions, sham SMT or as an adjunct therapy for acute low back pain.[107] The same review found that SMT appears to be no better than other recommended therapies.[107] A 2012 overview of systematic reviews found that collectively, SM failed to show it is an effective intervention for pain.[108] A 2011 Cochrane review found strong evidence that suggests there is no clinically meaningful difference between SMT and other treatments for reducing pain and improving function for chronic low back pain.[109] A 2010 Cochrane review found no difference between the effects of combined chiropractic treatments and other treatments for chronic or mixed duration low back pain.[110] A 2010 systematic review found that most studies suggest SMT achieves equivalent or superior improvement in pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up.[111]
- Whiplash and other neck pain. There is no consensus on the effectiveness of manual therapies for neck pain.[115] A 2013 systematic review found that the data suggests that there are minimal short- and long-term treatment differences when comparing manipulation or mobilization of the cervical spine to physical therapy or exercise for neck pain improvement.[116] A 2013 systematic review found that although there is insufficient evidence that thoracic SM is more effective than other treatments, it is a suitable intervention to treat some patients with non-specific neck pain.[117] A 2011 systematic review found that thoracic SM may offer short-term improvement for the treatment of acute or subacute mechanical neck pain; although the body of literature is still weak.[118] A 2010 Cochrane review found low quality evidence that suggests cervical manipulation may offer better short-term pain relief than a control for neck pain, and moderate evidence that cervical manipulation and mobilization produced similar effects on pain, function and patient satisfaction.[119] A 2010 systematic review found low level evidence that suggests chiropractic care improves cervical range of motion and pain in the management of whiplash.[120]
- Headache. There is conflicting evidence surrounding the use of chiropractic SMT for the treatment and prevention of migraine headaches.[121][122] A 2006 review found no rigorous evidence supporting SM or other manual therapies for tension headache.[123] A 2005 review found that the evidence was weak for effectiveness of chiropractic manipulation for tension headache, and that it was probably more effective for tension headache than for migraine.[124]
- Extremity conditions. A 2011 systematic review and meta-analysis concluded that the addition of manual mobilizations to an exercise program for the treatment of knee osteoarthritis resulted in better pain relief than a supervised exercise program alone and suggested that manual therapists consider adding manual mobilization to optimize supervised active exercise programs.
- Other. A 2012 systematic review found insufficient low bias evidence to support the use of spinal manipulation as a therapy for the treatment of hypertension.postmenopausal symptoms,[145] or pelvic and back pain during pregnancy.[146] As there is no evidence of effectiveness or safety for cervical manipulation for baby colic, it is not endorsed.[147]
Safety
The World Health Organization found chiropractic care in general is safe when employed skillfully and appropriately.[54] There is not sufficient data to establish the safety of chiropractic manipulations.[13] Manipulation is regarded as relatively safe but complications can arise, and it has known adverse effects, risks and contraindications.[54] Absolute contraindications to spinal manipulative therapy are conditions that should not be manipulated; these contraindications include rheumatoid arthritis and conditions known to result in unstable joints.[54] Relative contraindications are conditions where increased risk is acceptable in some situations and where low-force and soft-tissue techniques are treatments of choice; these contraindications include osteoporosis.[54] Although most contraindications apply only to manipulation of the affected region, some neurological signs indicate referral to emergency medical services; these include sudden and severe headache or neck pain unlike that previously experienced.[148] Indirect risks of chiropractic involve delayed or missed diagnoses through consulting a chiropractor.[8]
Spinal manipulation is associated with frequent, mild and temporary
Chiropractors sometimes employ diagnostic imaging techniques such as X-rays and CT scans that rely on ionizing radiation.[165] Although there is no clear evidence to justify the practice, some chiropractors still X-ray a patient several times a year.[57] Practice guidelines aim to reduce unnecessary radiation exposure,[165] which increases cancer risk in proportion to the amount of radiation received.[166] Research suggests that radiology instruction given at chiropractic schools worldwide seem to be evidence-based.[56] Although, there seems to be a disparity between some schools and available evidence regarding the aspect of radiography for patients with acute low back pain without an indication of a serious disease, which may contribute to chiropractic overuse of radiography for low back pain.[56]
Risk-benefit
A 2012 systematic review concluded that no accurate assessment of risk-benefit exists for cervical manipulation.[15] A 2010 systematic review stated that there is no good evidence to assume that neck manipulation is an effective treatment for any medical condition and suggested a precautionary principle in healthcare for chiropractic intervention even if a causality with vertebral artery dissection after neck manipulation were merely a remote possibility.[17] The same review concluded that the risk of death from manipulations to the neck outweighs the benefits.[17] Chiropractors have criticized this conclusion, claiming that the author did not evaluate the potential benefits of spinal manipulation.[167] Edzard Ernst stated "This detail was not the subject of my review. I do, however, refer to such evaluations and should add that a report recently commissioned by the General Chiropractic Council did not support many of the outlandish claims made by many chiropractors across the world."[167] A 1999 review of 177 previously reported cases published between 1925 and 1997 in which injuries were attributed to manipulation of the cervical spine (MCS) concluded that "The literature does not demonstrate that the benefits of MCS outweigh the risks." The professions associated with each injury were assessed. Physical therapists (PT) were involved in less than 2% of all cases, with no deaths caused by PTs. Chiropractors were involved in a little more than 60% of all cases, including 32 deaths.[168]
A 2009 review evaluating maintenance chiropractic care found that spinal manipulation is associated with considerable harm and no compelling evidence exists to indicate that it adequately prevents symptoms or diseases, thus the risk-benefit is not evidently favorable.[12]
Cost-effectiveness
A 2012 systematic review suggested that the use of spine manipulation in clinical practice is a
A 2006 systematic cost-effectiveness review found that the reported cost-effectiveness of spinal manipulation in the United Kingdom compared favorably with other treatments for back pain, but that reports were based on data from clinical trials without placebo controls and that the specific cost-effectiveness of the treatment (as opposed to non-specific effects) remains uncertain.[170] A 2005 American systematic review of economic evaluations of conservative treatments for low back pain found that significant quality problems in available studies meant that definite conclusions could not be drawn about the most cost-effective intervention.[171] The cost-effectiveness of maintenance chiropractic care is unknown.[106][non-primary source needed]
Analysis of a clinical and cost utilization data from the years 2003 to 2005 by an integrative medicine independent physician association (IPA) which looked the chiropractic services utilization found that the clinical and cost utilization of chiropractic services based on 70,274 member-months over a 7-year period decreased patient costs associate with the following use of services by 60% for in-hospital admissions, 59% for hospital days, 62% for outpatient surgeries and procedures, and 85% for pharmaceutical costs when compared with conventional medicine (visit to a medical doctor primary care provider) IPA performance for the same health maintenance organization product in the same geography and time frame.[172]
Education, licensing, and regulation
Requirements vary between countries. In the U.S. chiropractors obtain a non-medical accredited diploma in the field of chiropractic.
Upon graduation, there may be a requirement to pass national, state, or provincial board examinations before being
In the U.S., chiropractic schools are accredited through the
Regulatory colleges and chiropractic boards in the U.S., Canada, Mexico, and Australia are responsible for protecting the public, standards of practice, disciplinary issues, quality assurance and maintenance of competency.[192][193] There are an estimated 49,000 chiropractors in the U.S. (2008),[194] 6,500 in Canada (2010),[195] 2,500 in Australia (2000),[29] and 1,500 in the UK (2000).[196]
Chiropractors often argue that this education is as good as or better than medical physicians', but most chiropractic training is confined to classrooms with much time spent learning theory, adjustment, and marketing.[76] The fourth year of chiropractic education persistently showed the highest stress levels.[197] Every student, irrespective of year, experienced different ranges of stress when studying.[197] The chiropractic leaders and colleges have had internal struggles.[198] Rather than cooperation, there has been infighting between different factions.[198] A number of actions were posturing due to the confidential nature of the chiropractic colleges in an attempt to enroll students.[198][clarification needed]
Ethics
The chiropractic oath is a modern variation of the classical
A 2008 commentary proposed that the chiropractic profession actively regulate itself to combat abuse, fraud, and quackery, which are more prevalent in chiropractic than in other health care professions, violating the social contract between patients and physicians.[36] According to a 2015 Gallup poll of U.S. adults, the perception of chiropractors is generally favorable; two-thirds of American adults agree that chiropractors have their patient's best interest in mind and more than half also agree that most chiropractors are trustworthy. Less than 10% of US adults disagreed with the statement that chiropractors were trustworthy.[202][203]
Chiropractors, especially in America, have a reputation for unnecessarily treating patients.[57] In many circumstances the focus seems to be put on economics instead of health care.[57] Sustained chiropractic care is promoted as a preventive tool, but unnecessary manipulation could possibly present a risk to patients.[8] Some chiropractors are concerned by the routine unjustified claims chiropractors have made.[8] A 2010 analysis of chiropractic websites found the majority of chiropractors and their associations made claims of effectiveness not supported by scientific evidence, while 28% of chiropractor websites advocate lower back pain care, which has some sound evidence.[206]
The US
In 2009, a backlash to the libel suit filed by the British Chiropractic Association (BCA) against Simon Singh inspired the filing of formal complaints of false advertising against more than 500 individual chiropractors within one 24-hour period,[208][209] prompting the McTimoney Chiropractic Association to write to its members advising them to remove leaflets that make claims about whiplash and colic from their practice, to be wary of new patients and telephone inquiries, and telling their members: "If you have a website, take it down NOW" and "Finally, we strongly suggest you do NOT discuss this with others, especially patients."[208] An editorial in Nature suggested that the BCA may have been trying to suppress debate and that this use of English libel law was a burden on the right to freedom of expression, which is protected by the European Convention on Human Rights.[210] The libel case ended with the BCA withdrawing its suit in 2010.[211][212]
Reception
Chiropractic is established in the U.S., Canada, and Australia, and is present to a lesser extent in many other countries.
Australia
In Australia, there are approximately 2488 chiropractors, or one chiropractor for every 7980 people.[213] Most private health insurance funds in Australia cover chiropractic care, and the federal government funds chiropractic care when the patient is referred by a medical practitioner.[214] In 2014, the chiropractic profession had a registered workforce of 4,684 practitioners in Australia represented by two major organizations – the Chiropractors' Association of Australia (CAA) and the Chiropractic and Osteopathic College of Australasia (COCA).[215] Annual expenditure on chiropractic care (alone or combined with osteopathy) in Australia is estimated to be between AUD$750–988 million with musculoskeletal complaints such as back and neck pain making up the bulk of consultations; and proportional expenditure is similar to that found in other countries.[215] While Medicare (the Australian publicly funded universal health care system) coverage of chiropractic services is limited to only those directed by a medical referral to assist chronic disease management, most private health insurers in Australia do provide partial reimbursement for a wider range of chiropractic services in addition to limited third party payments for workers compensation and motor vehicle accidents.[215]
Of the 2,005 chiropractors who participated in a 2015 survey, 62.4% were male and the average age was 42.1 (SD = 12.1) years.[215] Nearly all chiropractors (97.1%) had a bachelor's degree or higher, with the majority of chiropractor's highest professional qualification being a bachelor or double bachelor's degree (34.6%), followed by a master's degree (32.7%), Doctor of Chiropractic (28.9%) or PhD (0.9%).[215] Only a small number of chiropractor's highest professional qualification was a diploma (2.1%) or advanced diploma (0.8%).[215]
Germany
In Germany, chiropractic may be offered by medical doctors and alternative practitioners. Chiropractors qualified abroad must obtain a German non-medical practitioner license. Authorities have routinely required a comprehensive knowledge test for this, but in the recent past, some administrative courts have ruled that training abroad should be recognised.[216]
Switzerland
In Switzerland, only trained medical professionals are allowed to offer chiropractic. There are 300 chiropractors in Switzerland.[217]
United Kingdom
In the United Kingdom, there are over 2,000 chiropractors, representing one chiropractor per 29,206 people.[213] Chiropractic is available on the National Health Service in some areas, such as Cornwall, where the treatment is only available for neck or back pain.[218]
A 2010 study by questionnaire presented to UK chiropractors indicated only 45% of chiropractors disclosed to patients the serious risk associated with manipulation of the cervical spine and that 46% believed there was possibility patients would refuse treatment if the risks were correctly explained. However 80% acknowledged the ethical/moral responsibility to disclose risk to patients.[219]
United States and Canada
The percentage of the population that utilizes chiropractic care at any given time generally falls into a range from 6% to 12% in the U.S. and Canada,[220] with a global high of 20% in Alberta in 2006.[221] In 2008, chiropractors were reported to be the most common CAM providers for children and adolescents, these patients representing up to 14% of all visits to chiropractors.[222]
There were around 50,330 chiropractors practicing in North America in 2000.[213] In 2008, this has increased by almost 20% to around 60,000 chiropractors.[8] In 2002–03, the majority of those who sought chiropractic did so for relief from back and neck pain and other neuromusculoskeletal complaints;[20] most do so specifically for low back pain.[20][220] The majority of U.S. chiropractors participate in some form of managed care.[9] Although the majority of U.S. chiropractors view themselves as specialists in neuromusculoskeletal conditions, many also consider chiropractic as a type of primary care.[9] In the majority of cases, the care that chiropractors and physicians provide divides the market, however for some, their care is complementary.[9]
In the U.S., chiropractors perform over 90% of all manipulative treatments.[223] Satisfaction rates are typically higher for chiropractic care compared to medical care, with a 1998 U.S. survey reporting 83% of respondents satisfied or very satisfied with their care; quality of communication seems to be a consistent predictor of patient satisfaction with chiropractors.[224]
Utilization of chiropractic care is sensitive to the costs incurred by the co-payment by the patient.[1] The use of chiropractic declined from 9.9% of U.S. adults in 1997 to 7.4% in 2002; this was the largest relative decrease among CAM professions, which overall had a stable use rate.[225] As of 2007 7% of the U.S. population is being reached by chiropractic.[226] They were the third largest medical profession in the US in 2002, following physicians and dentists.[227] Employment of U.S. chiropractors was expected to increase 14% between 2006 and 2016, faster than the average for all occupations.[194]
In the U.S., most states require insurers to cover chiropractic care, and most
History
Chiropractic's origins lie in the
Chiropractic competed with its predecessor osteopathy, another medical system based on magnetic healing; both systems were founded by charismatic midwesterners in opposition to the conventional medicine of the day, and both postulated that manipulation improved health.
Early chiropractors believed that all disease was caused by interruptions in the flow of innate intelligence, a
Chiropractic has seen considerable controversy and criticism.[25][26] Although D. D. and B. J. were "straight" and disdained the use of instruments, some early chiropractors, whom B. J. scornfully called "mixers", advocated the use of instruments.[22] In 1910, B. J. changed course and endorsed X-rays as necessary for diagnosis; this resulted in a significant exodus from the Palmer School of the more conservative faculty and students.[22] The mixer camp grew until by 1924 B. J. estimated that only 3,000 of the United States' 25,000 chiropractors remained straight.[22] That year, B. J.'s invention and promotion of the neurocalometer, a temperature-sensing device, was highly controversial among B. J.'s fellow straights. By the 1930s, chiropractic was the largest alternative healing profession in the U.S.[22]
Chiropractors faced heavy opposition from organized medicine.
Serious research to test chiropractic theories did not begin until the 1970s, and is continuing to be hampered by antiscientific and
Public health
Some chiropractors oppose vaccination and water fluoridation, which are common public health practices.[36] Within the chiropractic community there are significant disagreements about vaccination, one of the most cost-effective public health interventions available.[233] Most chiropractic writings on vaccination focus on its negative aspects,[28] claiming that it is hazardous, ineffective, and unnecessary.[29] Some chiropractors have embraced vaccination, but a significant portion of the profession rejects it, as original chiropractic philosophy traces diseases to causes in the spine and states that vaccines interfere with healing.[29] The extent to which anti-vaccination views perpetuate the current chiropractic profession is uncertain.[28] The American Chiropractic Association and the International Chiropractors Association support individual exemptions to compulsory vaccination laws, and a 1995 survey of U.S. chiropractors found that about a third believed there was no scientific proof that immunization prevents disease.[29] The Canadian Chiropractic Association supports vaccination;[28] a survey in Alberta in 2002 found that 25% of chiropractors advised patients for, and 27% against, vaccinating themselves or their children.[234]
Early opposition to water fluoridation included chiropractors, some of whom continue to oppose it as being incompatible with chiropractic philosophy and an infringement of personal freedom. Other chiropractors have actively promoted fluoridation, and several chiropractic organizations have endorsed scientific principles of public health.[235] In addition to traditional chiropractic opposition to water fluoridation and vaccination, chiropractors' attempts to establish a positive reputation for their public health role are also compromised by their reputation for recommending repetitive lifelong chiropractic treatment.[36]
Controversy
Throughout its history chiropractic has been the subject of internal and external controversy and criticism.

Archived July 19, 2020, at the Wayback Machine --- "Daniel David Palmer, the 'father' of chiropractic who performed the first chiropractic adjustment in 1895, was an avid spiritualist. He maintained that the notion and basic principles of chiropractic treatment were passed along to him during a seance by a long-dead doctor. 'The knowledge and philosophy given me by Dr. Jim Atkinson, an intelligent spiritual being ... appealed to my reason,' Palmer wrote in his memoir The Chiropractor, which was published in 1914 after his death in Los Angeles.

A significant and continuing barrier to scientific progress within chiropractic are the anti-scientific and pseudo-scientific ideas (Keating 1997b) which have sustained the profession throughout a century of intense struggle with political medicine. Chiropractors' tendency to assert the meaningfulness of various theories and methods as a counterpoint to allopathic charges of quackery has created a defensiveness which can make critical examination of chiropractic concepts difficult (Keating and Mootz 1989). One example of this conundrum is the continuing controversy about the presumptive target of DCs' adjustive interventions: subluxation (Gatterman 1995; Leach 1994).

Although the risk of injury associated with MCS appears to be small, this type of therapy has the potential to expose patients to vertebral artery damage that can be avoided with the use of mobilization (nonthrust passive movements). The literature does not demonstrate that the benefits of MCS outweigh the risks. Several recommendations for future studies and for the practice of MCS are discussed.
