Patients in Medicare Demonstration Project Give Their Chiropractors High Marks

When asked to rate their satisfaction on a 10-point scale: 87 percent of patients in the study gave their doctor of chiropractic a level of 8 or higher, and 56 percent of those patients rated their chiropractor with a perfect 10.


Consumer Reports Lists Chiropractic Patients As Most Satisfied

A study in the May issue of Consumer Reports shows that hands-on therapies were top among treatments for relief of back pain. The study, which surveyed more than 14,000 consumers, was conducted by the Consumer Reports Health Ratings Center. The report states that, “eighty-eight percent of those who tried chiropractic said it helped a lot, and 59 percent were ‘completely’ or ‘very’ satisfied with their chiropractor.”


Chiropractic Services in the Canadian Armed Forces: A Pilot Project

This article reports on satisfaction associated with the introduction of chiropractic services within a military hospital, through a Canadian Armed Forces Pilot Project on 102 military personnel presenting for on-site chiropractic services at the Archie McCallum Hospital in Halifax, Nova Scotia. The majority of military personnel (94.2%) and referring physicians (80.0%) expressed satisfaction with chiropractic services.

The “Manga Report” by the Canadian Government

This comprehensive government study reviewed all the published literature on low back pain and concluded that:

  • Chiropractic should be the treatment of choice for low back pain – and traditional medical care be excluded from treating low back pain altogether!
  • Chiropractic management of low-back pain is more cost-effective than medical management
  • Chiropractic services should be fully insured under the Ontario Health Insurance Plan
  • Chiropractic services should be fully integrated into the health care system
  • Because of the high incidence and cost of low back pain, hospitals, managed health care groups, community health centres, comprehensive health organisations, health service organisations, and long-term care facilities should all employ chiropractors on a full-time and/or part-time basis

The New Zealand Government Inquiry into Chiropractic Safety & Effectiveness

  • Commissioned by the New Zealand Government in 1978, The New Zealand Report developed into the most comprehensive and detailed independent examination, at that time, of chiropractic ever undertaken in any country
  • Chiropractors are the only health practitioners who are necessarily equipped by their education and training to carry out spinal manual therapy
  • Spinal manual therapy in the hands of a registered chiropractor is safe
  • The education and training of a registered chiropractor are sufficient to enable him/her to determine whether there are contraindications to spinal manual therapy in a particular case, and whether the patient should have medical care instead of or as well as chiropractic care
  • Spinal manual therapy can be effective in relieving musculoskeletal symptoms, such as back pain and other symptoms known to respond to such therapy, such as migraine
  • In a limited number of cases where there are organic and/or visceral symptoms, chiropractic treatment may provide relief, but this is unpredictable, and in such cases the patient should be under concurrent medical care if that is practicable
  • In the public interest and in the interests of patients, there must be no impediment to full professional cooperation between chiropractors and medical practitioners
  • The responsibility for spinal manual therapy training, because of its specialised nature, should lie with the chiropractic profession
  • Part‑time or vacation courses in spinal manual therapy for other health professionals should not be encouraged

Safety of chiropractic for babies and children

  • This study on the safety of chiropractic for children found that out of 5,438 office visits, only 3 adverse events were reported from the adjustments – a .00055 percent chance of negative reaction. The 3 events reported were of temporary minor discomfort following the adjustment, which was readily resolved with continued adjustments. The study demonstrates a risk factor well below 1 percent, showing that children have over a 99 percent chance of experiencing zero problems when receiving chiropractic care.

Safety of Neck Adjustments

Chiropractic is extremely safe and has an amazing track record. Recently it has been calculated by epidemiologist Dr Scott Haldemann that the estimated incidence of stroke following cervical manipulation was found to be one per 5.85 million cervical adjustments. That means that for an average chiropractor they would have to work for 1430 years before encountering such a case!

Safety of Low Back Adjustments

Only 8 cases of low back disc injury as a complication of chiropractic care have been reported over the last 80 years in the French, German and English literature. This sort of safety record is unheard of with medical intervention.

American Medical Association Recommends Chiropractic Before Resorting to Surgery

The Journal of the American Medical Association released new guidelines for back pain treatment that encouraged patients to seek chiropractic and physical therapy before resorting to surgery.

Chiropractic as Effective as Epidural Injections for Lumbar Disc Herniation

Patients with lumbar disc herniation were randomly assigned to receive either nerve root injections or chiropractic care. Overall, 76% of chiropractic patients reported feeling “better” or “much better” after treatment compared to just 62.5% of injection patients.

DISCLAIMER: Chiropractic is still not officially recognised & regulated as a health profession in Spain – click here for details.
CHIROPRACTIC, whilst recognised as a health profession by the World Health Organisation (WHO), and forming part of the healthcare system in most developed countries including European countries such as Britain, France, Portugal, Italy, Denmark and Switzerland – many of which recognise it as a primary healthcare profession – WITHIN SPAIN IT IS NOT A RECOGNISED HEALTH PROFESSION AND IS NOT SUBJECT TO REGULATION BY THE SPANISH GOVERNMENT. Because health legislation is a matter of regulatory law under the sovereignty of each EU member country, the chiropractic profession finds itself in a legal vacuum in Spain, meaning there are no laws to regulate it. The Spanish Association of Chiropractors (A.E.Q.) has petitioned the courts and relevant health and education ministries requesting that Parliament boost the legislative process to officially recognise chiropractic as a health profession in Spain. In countries legally recognising chiropractic as a health profession, the chiropractic degree is obtained after 5-6 years of educational training. Two Spanish institutions currently offer five-year chiropractic programs (with unofficial titles) in anticipation of the legal recognition of the profession in Spain: the Real Central University Maria Cristina of Madrid (UCR) and the Barcelona College of Chiropractic (BCC). The training from these institutions meet all the standards of quality and excellence demanded by the European Council of Chiropractic Education (ECCE), and paradoxically, Spanish graduates may work as official chiropractic health professionals in other countries like the United States, France or England, but not in their own country. The A.E.Q. was created and recognised by the Ministerio del Interior in 1986, and has over 200 members with chiropractic degrees recognised by the European Council of Chiropractic, ensuring compliance with the highest standards of professional practice at a European level. Unfortunately so far, these degrees and diplomas ARE NOT RECOGNISED AS OFFICIAL TITLES IN SPAIN. To ensure your chiropractor meets the quality standards established by ECCE regulation of chiropractic in Spain, check and verify that they are a member of the A.E.Q. in “Find a chiropractor” on the website: The regulation of chiropractic in Spain is a matter of political expediency, but in the meantime chiropractic professionals who meet the requirements of the AEQ statutes find themselves in a situation of legal uncertainty and disadvantage compared to other professionals from neighbouring European countries. Additionally due to the lack of regulation, Spanish citizens may be treated by unqualified people claiming to be chiropractors who do not meet the minimum international standards.
