History of Chiropractic Care
The roots of chiropractic care can be traced all the way back to the beginnng of recorded time. Writings from China and Greece written in 2700 B.C. and 1500 B.C. mention spinal manipulation and the maneuvering of the lower extremities to ease low back pain. Hippocrates, the Greek physician, who lived from 460 to 357 B.C., also published texts detailing the importance of chiropractic care. In one of his writings he declares, “Get knowledge of the spine, for this is the requisite for many diseases”.
In the United States, the practice of spinal manipulation began gaining momentum in the late nineteenth century. In 1895, Daniel David Palmer founded the Chiropractic profession in Davenport, Iowa. Palmer was well read in medical journals of his time and had great knowledge of the developments that were occurring throughout the world regarding anatomy and physiology. In 1897, Daniel David Palmer went on to begin the Palmer School of Chiropractic, which has continued to be one of the most prominent chiropractic colleges in the nation.
Throughout the twentieth century, doctors of chiropractic gained legal recognition in all fifty states. A continuing recognition and respect for the chiropractic profession in the United States has led to growing support for chiropractic care all over the world. The research that has emerged from ” around the world” has yielded incredibly influential results, which have changed, shaped and molded perceptions of chiropractic care. The report, Chiropractic in New Zealand published in 1979 strongly supported the efficacy of chiropractic care and elicited medical cooperation in conjunction with chiropractic care. The 1993 Manga study published in Canada investigated the cost effectiveness of chiropractic care. The results of this study concluded that chiropractic care would save hundreds of millions of dollars annually with regard to work disability payments and direct health care costs.
Doctors of chiropractic have become pioneers in the field of non-invasive care promoting science-based approaches to a variety of ailments. A continuing dedication to chiropractic research could lead to even more discoveries in preventing and combating maladies in future years.
Education of Doctors of Chiropractic
Doctors of chiropractic must complete four to five years at an accredited chiropractic college. The complete curriculum includes a minimum of 4,200 hours of classroom, laboratory and clinical experience. Approximately 555 hours are devoted to learning about adjustive techniques and spinal analysis in colleges of chiropractic. In medical schools, training to become proficient in manipulation is generally not required of, or offered to, students. The Council on Chiropractic Education requires that students have 90 hours of undergraduate courses with science as the focus.
Those intending to become doctors of chiropractic must also pass the national board exam and all exams required by the state in which the individual wishes to practice. The individual must also meet all individual state licensing requirements in order to become a doctor of chiropractic.
An individual studying to become a doctor of chiropractic receives an education in both the basic and clinical sciences and in related health subjects. The intention of the basic chiropractic curriculum is to provide an in-depth understanding of the structure and function of the human body in health and disease. The educational program includes training in the basic medical sciences, including anatomy with human dissection, physiology, and biochemistry. Thorough training is also obtained in differential diagnosis, radiology and therapeutic techniques. This means, a doctor of chiropractic can both diagnose and treat patients, which separates them from non-physician status providers, like physical therapists. According to the Council on Chiropractic Education DCs are trained as Primary care Providers.
What is a Doctor of Chiropractic?
The proper title for a doctor of chiropractic is “doctor” as they are considered physicians under Medicare and in the overwhelming majority of states. The professional credentials abbreviation ” D.C.” means doctor of chiropractic. ACA also advocates in its Policies on Public Health that DCs may be referred to as (chiropractic) physicians as well.
As a profession, the primary belief is in natural and conservative methods of health care. Doctors of chiropractic have a deep respect for the human body’s ability to heal itself without the use of surgery or medication. These doctors devote careful attention to the biomechanics, structure and function of the spine, its effects on the musculoskeletal and neurological systems, and the role played by the proper function of these systems in the preservation and restoration of health. A Doctor of chiropractic is one who is involved in the treatment and prevention of disease, as well as the promotion of public health, and a wellness approach to patient healthcare.
Scope of Practice
Doctors of chiropractic frequently treat individuals with neuromusculoskeletal complaints, such as headaches, joint pain, neck pain, low back pain and sciatica. Chiropractors also treat patients with osteoarthritis, spinal disk conditions, carpal tunnel syndrome, tendonitis, sprains, and strains. However, the scope of conditions that Doctors of chiropractic manage or provide care for is not limited to neuromusculoskeletal disorders. Chiropractors have the training to treat a variety of non-neuromusculoskeletal conditions such as: allergies, asthma, digestive disorders, otitis media (non-suppurative) and other disorders as new research is developed.
A variety of techniques, treatment and procedure are used to restore healing which will be the topic of future education releases.
A growing list of research studies demonstrate that chiropractic care is both safe and effective. Following are excerpts and summaries from a few of the more recent studies. The evidence strongly supports the natural, whole-body and cost-effective approach of chiropractic care for a variety of conditions.
For Acute and Chronic Pain
“Patients with chronic low-back pain treated by chiropractors showed greater improvement and satisfaction at one month than patients treated by family physicians. Satisfaction scores were higher for chiropractic patients. A higher proportion of chiropractic patients (56 percent vs. 13 percent) reported that their low-back pain was better or much better, whereas nearly one-third of medical patients reported their low-back pain was worse or much worse.”
– Nyiendo et al (2000), Journal of Manipulative and Physiological Therapeutics
In a Randomized controlled trial, 183 patients with neck pain were randomly allocated to manual therapy (spinal mobilization), physiotherapy (mainly exercise) or general practitioner care (counseling, education and drugs) in a 52-week study. The clinical outcomes measures showed that manual therapy resulted in faster recovery than physiotherapy and general practitioner care. Moreover, total costs of the manual therapy-treated patients were about one-third of the costs of physiotherapy or general practitioner care.

In Comparison to Other Treatment Alternatives
“Reduced odds of surgery were observed for…those whose first provider was a chiropractor. 42.7% of workers [with back injuries] who first saw a surgeon had surgery, in contrast to only 1.5% of those who saw a chiropractor.”
– Keeney et al (2012), Spine
“Acute and chronic chiropractic patients experienced better outcomes in pain, functional disability, and patient satisfaction; clinically important differences in pain and disability improvement were found for chronic patients.”
– Haas et al (2005), Journal of Manipulative and Physiological Therapeutics
“In our randomized, controlled trial, we compared the effectiveness of manual therapy, physical therapy, and continued care by a general practitioner in patients with nonspecific neck pain. The success rate at seven weeks was twice as high for the manual therapy group (68.3 percent) as for the continued care group (general practitioner). Manual therapy scored better than physical therapy on all outcome measures. Patients receiving manual therapy had fewer absences from work than patients receiving physical therapy or continued care, and manual therapy and physical therapy each resulted in statistically significant less analgesic use than continued care.”
– Hoving et al (2002), Annals of Internal Medicine
“Cervical spine manipulation was associated with significant improvement in headache outcomes in trials involving patients with neck pain and/or neck dysfunction and headache.”
— Duke Evidence Report, McCrory, Penzlen, Hasselblad, Gray (2001)
“The results of this study show that spinal manipulative therapy is an effective treatment for tension headaches. . . Four weeks after cessation of treatment . . . the patients who received spinal manipulative therapy experienced a sustained therapeutic benefit in all major outcomes in contrast to the patients that received amitriptyline therapy, who reverted to baseline values.” ‘
— Journal of Manipulative and Physiological Therapeutics, Boline et al. (1995)
For Neck Pain
In a study funded by NIH’s National Center for Complementary and Alternative Medicine to test the effectiveness of different approaches for treating mechanical neck pain, 272 participants were divided into three groups that received either spinal manipulative therapy (SMT) from a doctor of chiropractic (DC), pain medication (over-the-counter pain relievers, narcotics and muscle relaxants) or exercise recommendations. After 12 weeks, about 57 percent of those who met with DCs and 48 percent who exercised reported at least a 75 percent reduction in pain, compared to 33 percent of the people in the medication group. After one year, approximately 53 percent of the drug-free groups continued to report at least a 75 percent reduction in pain; compared to just 38 percent pain reduction among those who took medication.
— Annals of Internal Medicine, Bronfort et al. (2012)
Low back pain initiated with a doctor of chiropractic (DC) saves 40 percent on health care costs when compared with care initiated through a medical doctor (MD), according to a study that analyzed data from 85,000 Blue Cross Blue Shield (BCBS) beneficiaries in Tennessee over a two-year span. The study population had open access to MDs and DCs through self-referral, and there were no limits applied to the number of MD/DC visits allowed and no differences in co-pays. Researchers estimated that allowing DC-initiated episodes of care would have led to an annual cost savings of $2.3 million for BCBS of Tennessee. They also concluded that insurance companies that restrict access to chiropractic care for low back pain treatment may inadvertently pay more for care than they would if they removed such restrictions.
– Liliedahl et al (2010), Journal of Manipulative and Physiological Therapeutics
“Chiropractic care appeared relatively cost-effective for the treatment of chronic low-back pain. Chiropractic and medical care performed comparably for acute patients. Practice-based clinical outcomes were consistent with systematic reviews of spinal manipulative efficacy: manipulation-based therapy is at least as good as and, in some cases, better than other therapeusis.”
– Haas et al (2005), Journal of Manipulative and Physiological Therapeutics
“Chiropractic patients were found to be more satisfied with their back care providers after four weeks of treatment than were medical patients. Results from observational studies suggested that back pain patients are more satisfied with chiropractic care than with medical care. Additionally, studies conclude that patients are more satisfied with chiropractic care than they were with physical therapy after six weeks.”
— Hertzman-Miller et al (2002), American Journal of Public Health
Popularity of Chiropractic
“Chiropractic is the largest, most regulated, and best recognized of the complementary and alternative medicine (CAM) professions. CAM patient surveys show that chiropractors are used more often than any other alternative provider group and patient satisfaction with chiropractic care is very high. There is steadily increasing patient use of chiropractic in the United States, which has tripled in the past two decades.”
– Meeker, Haldeman (2002), Annals of Internal Medicine
Frequently Asked Questions
What conditions do chiropractors treat?
Doctors of Chiropractic (DCs) care for patients of all ages, with a variety of health conditions. DCs are especially well known for their expertise in caring for patients with back pain, neck pain and headaches…particularly with their highly skilled manipulations or chiropractic adjustments. They also care for patients with a wide range of injuries and disorders of the musculoskeletal system, involving the muscles, ligaments and joints. These painful conditions often involve or impact the nervous system, which can cause referred pain and dysfunction distant to the region of injury. The benefits of chiropractic care extend to general health issues, as well, since our body structure affects our overall function. DCs also counsel patients on diet, nutrition, exercise, healthy habits, and occupational and lifestyle modification.
How do I select a doctor of chiropractic?
One of the best ways to select a doctor of chiropractic (DC) is by getting a referral from a friend, family member, colleague, or another health care provider. You can also locate a DC near you by using the American Chiropractic Association’s Find a Doctor search tool, www.acatoday.org/DocSearch.
Does chiropractic treatment require a referral from an MD?
A referral is usually not needed to see a doctor of chiropractic (DC); however, your health plan may have specific referral requirements. You may want to contact your employer’s human resources department—or the insurance plan directly—to find out if there are any referral requirements. Most plans allow you to just call and schedule an appointment with a DC.
Is chiropractic treatment safe?
Chiropractic is widely recognized as one of the safest drug-free, non-invasive therapies available for the treatment of neuromusculoskeletal complaints. Although chiropractic has an excellent safety record, no health treatment is completely free of potential adverse effects. The risks associated with chiropractic, however, are very small. Many patients feel immediate relief following chiropractic treatment, but some may experience mild soreness or aching, just as they do after some forms of exercise. Current literature shows that minor discomfort or soreness following spinal manipulation typically fades within 24 hours.
Neck pain and some types of headaches are treated through precise cervical manipulation. Cervical manipulation, often called a neck adjustment, works to improve joint mobility in the neck, restoring range of motion and reducing muscle spasm, which helps relieve pressure and tension. Neck manipulation is a remarkably safe procedure. While some reports have associated upper high-velocity neck manipulation with a certain kind of stroke, or vertebral artery dissection, recent evidence suggests that this type of arterial injury often takes place spontaneously, or following everyday activities such as turning the head while driving, swimming, or having a shampoo in a hair salon. Patients with this condition may experience neck pain and headache that leads them to seek professional care—often at the office of a doctor of chiropractic or family physician—but that care is not the cause of the injury. The best evidence indicates that the incidence of artery injuries associated with high-velocity upper neck manipulation is extremely rare – about 1 case in 5.85 million manipulations.
If you are visiting your doctor of chiropractic with upper-neck pain or headache, be very specific about your symptoms. This will help your doctor of chiropractic offer the safest and most effective treatment, even if it involves referral to another health care provider.
It is important for patients to understand the risks associated with some of the most common treatments for musculoskeletal pain — prescription and over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDS) — as these treatments may carry risks significantly greater than those of chiropractic manipulation. According to a study from the American Journal of Gastroenterology, approximately one-third of all hospitalizations and deaths related to gastrointestinal bleeding can be attributed to the use of aspirin or NSAID painkillers like ibuprofen.
Is chiropractic treatment appropriate for children?
Yes, children can benefit from chiropractic care. Children are very physically active and experience many types of falls and blows from activities of daily living as well as from participating in sports. Injuries such as these may cause many symptoms including back and neck pain, stiffness, soreness or discomfort. Chiropractic care is always adapted to the individual patient. It is a highly skilled treatment, and in the case of children, very gentle.
Are chiropractors allowed to practice in hospitals or use medical outpatient facilities?
Chiropractors are being recognized to admit and treat patients in hospitals and to use outpatient clinical facilities (such as labs, x-rays, etc.) for their non-hospitalized patients. Hospital privileges were first granted in 1983.
Do insurance plans cover chiropractic?
Yes. Chiropractic care is included in most health insurance plans, including major medical plans, workers’ compensation, Medicare, some Medicaid plans, and Blue Cross Blue Shield plans for federal employees, among others. Chiropractic care is also available to active-duty members of the armed forces at more than 60 military bases and is available to veterans at 36 major veterans medical facilities.
What type of education and training do chiropractors have?
Doctors of chiropracticare educated as primary-contact health care providers, with an emphasis on diagnosis and treatment of conditions related to the musculoskeletal system (the muscles, ligaments and joints of the spine and extremities) and the nerves that supply them. Educational requirements for doctors of chiropractic are among the most stringent of any of the health care professions.
The typical applicant for chiropractic college has already acquired nearly four years of pre-medical undergraduate college education, including courses in biology, inorganic and organic chemistry, physics, psychology and related lab work. Once accepted into an accredited chiropractic college, the requirements become even more demanding — four to five academic years of professional study are the standard. Doctors of chiropractic are educated in orthopedics, neurology, physiology, human anatomy, clinical diagnosis including laboratory procedures, diagnostic imaging, exercise, nutrition rehabilitation and more.
Because chiropractic care includes highly skilled manipulation/adjusting techniques, a significant portion of time is spent in clinical technique training to master these important manipulative procedures.
In total, the chiropractic college curriculum includes a minimum of 4,200 hours of classroom, laboratory and clinical experience. The course of study is approved by an accrediting agency that is fully recognized by the U.S. Department of Education.
How is a chiropractic adjustment performed?
Chiropractic adjustment or manipulation is a manual procedure that utilizes the highly refined skills developed during the doctor of chiropractic’s intensive years of chiropractic education. The chiropractic physician typically uses his or her hands–or an instrument–to manipulate the joints of the body, particularly the spine, in order to restore or enhance joint function. This often helps resolve joint inflammation and reduces the patient’s pain. Chiropractic manipulation is a highly controlled procedure that rarely causes discomfort. The chiropractor adapts the procedure to meet the specific needs of each patient. Patients often note positive changes in their symptoms immediately following treatment.
Is chiropractic treatment ongoing?
The hands-on nature of the chiropractic treatment is essentially what requires patients to visit the chiropractor a number of times. To be treated by a chiropractor, a patient needs to be in his or her office. In contrast, a course of treatment from medical doctors often involves a pre-established plan that is conducted at home (i.e. taking a course of antibiotics once a day for a couple of weeks). A chiropractor may provide acute, chronic, and/or preventive care thus making a certain number of visits sometimes necessary. Your doctor of chiropractic should tell you the extent of treatment recommended and how long you can expect it to last.
Why is there a popping sound when a joint is adjusted?
Adjustment (or manipulation) of a joint may result in the release of a gas bubble between the joints, which makes a popping sound. The same thing occurs when you “crack” your knuckles. The noise is caused by the change of pressure within the joint, which results in gas bubbles being released. There is usually minimal, if any, discomfort involved.
