How Does Chiropractic Work

What’s the origin of chiropractic?

Spinal manipulation has been used for thousands of years around the world to try and fix health problems. The modern version was developed by Daniel D Palmer in the nineteenth century and called chiropractic from the Greek words for doing and hand (praktikos and cheiro).

Palmer’s first patient was his janitor who had been deaf for seventeen years following a neck injury. Palmer claimed to have ‘clicked’ a joint back into place and the man’s hearing returned. Palmer, however, was jailed for practising medicine without a licence but his son took up the cause and chiropractic began to become popular.

How does chiropractic work?

Chiropractors like many other complementary health practitioners look at the body as a whole when they treat you. A chiropractor considers the body to be like a living machine – if a joint is misaligned or damaged then the smooth running of the machine can be upset causing inflammation, pressure on nerves and subsequent medical problems.

Chiropractors believe stress, poor posture and accidents, including sports injuries and the like can all stop the body machine running smoothly. Almost any aspect of health might be affected by problems in the spine, they believe.

For instance, pressure on nerves connected to the intestines could be the root cause of some digestive disorders. Chiropractic manipulation of the spine at the point where these nerves emerge from the spinal cord through the vertebra could remedy such a disorder. There is no evidence that chiropractic can deal with anything other than back problems, however, an even then scant controlled clinical evidence is available for that.

What happens during a treatment?

Your first session with a chiropractor often involves an assessment of posture, mobility of joints, and usually lifestyle. There are various standard tests such as the Thomas test, which determines mobility in the hip joints, the Yeoman’s test which involves the practitioner flexing your legs one at a time to assess joints for sprain and mobility. The chiropractor might also ask you to bend, raise your legs, test your reflexes, take your blood pressure or even an X-ray to build up a more detailed picture of a problem.

As with osteopathy, chiropractors try to track down restricted or excessive joint movement, especially in the spine because they believe these problems are the cause of inflammation, swelling and pressure that leads to pain and illness.

A chiropractor might use some massage to loosen stiff muscles before focusing on the manipulation techniques. Manipulation usually involves a sharp, precise thrusting movement of a joint to ‘free it up’. There are several standard techniques aimed at making, what chiropractors refer to as, adjustments. However, a new school of thought among progressive chiropractors avoids the forceful thrusting manipulations and instead relies on more gentle and tempered movements and stretches.

For instance, the Toggle Drop involves a swift and precise pressure applied with the hands to specific verterbrae in the spine while you lie face down. The Bunyon adjustment involves the practitioner applying a stretch between vertebra – a traction – to adjust the spine. The various manipulations often causes clicking noises, which can be quite alarming to the patient and may cause a little pain or discomfort at the time but this quickly eases off and the procedure has been shown to be extremely safe. Clicking noises are not caused by bone against bone, they are simply the sound of gases “popping” as they are expelled from where they may be trapped in the membrane surrounding a joint.

Chiropractic will often attempt to provide an effective long-term management of a condition. However, patients are usually locked in to regular return visits for “maintenance” treatments to prevent them regressing. Chiropractors similarly to osteopaths will claim to help you improve your posture, suggest lifestyle changes that might help your overall health and teach you some easy exercises to do at home.

What problems can chiropractic help?

Chiropractors focus primarily on back problems, but there is a long list of other ailments, diseases and disorders that they offer to treat. Evidence for the more outlandish claims is almost wholly lacking. Commentators such as Ernst and Singh have written that such claims are allegedly “bogus”.

Indeed, one chiropractic association has recommended that its members remove reference to any non-evidence based claims from their websites pending a legal case involving Singh and the British Chiropractic Association. Specifically, they suggest that members remove patient information leaflets that practitioners can treat whiplash, colic or other childhood problems, as there is a serious risk practitioners might be prosecuted.

Of course, many have been too tardy to respond to this call to defence and Alex MacLean (yaxu on twitter) has apparently been scraping and archiving all the chiro sites making allegedly spurious claims about their practice.

Where’s the evidence?

There have been various clinical trials of chiropractic several of which have been reported by the well-respected British Medical Journal, published by the British Medical Association. The research reports that showed that chiropractic worked better at treating acute back pain than standard treatments offered in a hospital out-patients. Supposed evidence that chiropractic can treat other problems has been debunked.

What do conventional doctors think about chiropractic?

Chiropractic had a poor image among the medical profession for most of the last century, in the 1960s the American Medical Association condemned it as an ‘unscientific cult’ although the AMA lost its legal battle in 1987 and now chiropractors work in hospitals and sports clinics.

In Britain, in 1994 The Chiropractors’ Act gave them official recognition which means that if you use a registered chiropractor you have the security of knowing they are a state-registered health professional, for what that’s worth.

You are almost as likely to be referred to a chiropractor as an osteopath by your GP, but usually only for musculo-skeletal problems. Many doctors still prefer to send patients to an osteopath instead. However, clinics and community health centres often have chiropractors on-site apparently complementing the work of the doctors and nursing staff. One thing that more and more doctors agree on is that the old advice of long periods of lying flat and still or restrained in a medical corset are not the way to treat back problems.

What is a subluxation?

A medical subluxation is an incomplete or partial dislocation of a joint or organ. The World Health Organization (WHO) considers a subluxation to be a “significant structural displacement, and therefore visible on static imaging studies.” In the spine, such a displacement may be caused by a spondylolisthesis.

An orthopedic dislocation of any joint will usually need medical attention to help relocate or reduce the joint. Nursemaid’s elbow is the subluxation of the head of the radius from the annular ligament. Other joints that are prone to subluxations are the shoulders, fingers, kneecaps, and hips affected by hip dysplasia. A spinal subluxation is relatively rare, but can sometimes impinge on spinal nerve roots causing symptoms in the areas served by those roots.

Can chiropractors remedy subluxations?

Chiropractors talk of vertebral subluxations and have their own unique definition of this problem, they say it is relatively common and is apparent as a spinal vertebra having lost its proper juxtaposition, or alignment, with one or both of its neighbours. This apparently interferes with the nervous system. Conventional chiropractic attempts to remedy vertebral subluxations using manipulation techniques. However, even though research is ongoing mainstream medicine and even progressive chiropractors have often rejected the subluxation hypothesis.

  1. Yes, there is *some* evidence that it works for lower back problems. It’s all the spurious claims for asthma, period problems, and childhood cholic for which there is no apparent strong evidence.

    While I don’t believe that a Chiropractor can resolve all issues, I do believe they are effective and solving some issues.

    I am currently seeing a Chiropractor for some pain in the lower back. However, before going to Chiropractor, I went to my Orthopedic Surgeon. After performing X-rays and MRIs, the Ortho doc provided a list of possible treatments and near the top of his recommendations was to see a Chiropractor first along with some physical therapy to eliminate the pain in my lower back. He then gave the recommendation of a specific Chiro office.

    After 3 appts. so far, I do feel less pain in my lower back (probably about a 30% improvement so far). I think the pain reduction is due mostly to the adjustments because I have not yet really started the physical therapy, though the Chiro doc has given me a few core exercises to do.

    Therefore, in my opinion it does seem to be helping me….though I am just one case.

    I initially visited a chiropractor for my long-term, persistent back pain. X-rays, etc., confirmed my ‘need’ for frequent adjustments (3 times a week, at first) to restore alignment to my back, which I was told showed evidence of whiplash and side-impact trauma.

    After three YEARS of treatment – some of which was painful (I remember one particular adjustment from a certain substitute chiropractor to this day!) – when I made mention of the fact that my back still hurt, that it had actually gotten worse during the course of treatment, and that I suspected that the adjustments were actually the cause of my back pain and breathing issues, my chiropractor said that chiropractic doesn’t treat back pain!

    That was enough for me!

    To this day, I suffer from a sharp pain in the center of my back that I believe to be the result of that particularly vigorous adjustment I got from the substitute chiropractor.

    I now try to address my back issues with stretching exercises, a daily 3-mile walk, and hot baths with Epsom salts and oil of eucalyptus. This provides as much relief, if not more, than the chiropractic visits once did, and at greatly reduced expense!

    If chiropractic could fix something and it would stay fixed, or offer even the slightest suggestion of ways to avoid repeatedly suffering subluxations, I’d be more inclined to approve of it. But given the proclivity to lock someone into perpetual expensive treatment wherein nothing is done except exactly what was done in prior sessions along with the fact that no significant improvement or alleviation of discomfort whatsoever is experienced over the long term, I’d have to regard chiropractic as a treatment of last resort, no more than a frivolity or indulgence, something on the order of a tanning salon!

  4. @Barb If you actually read my post you’d see that I didn’t say chiropractic isn’t real. But, metaphors about garden hoses are irrelevant to actual physiology.

  5. Barb Barnett says:

    I didn’t know anything about Chiropractic until 1989. Then I went to work for one! She explained a subluxation like this: Basically, if a garden hose has a kink in it, the water will not flow freely from the end, and your garden will not get watered as well as it could. IF your spinal column is misaligned, and the bone pushes into a nerve, the organ or limb at the end of that nerve will not get the proper flow of blood, and thus, could be impaired. Chiropractic is not a ‘cure-all’, but it really makes sense when you look at how it works. When the bones of your spine are adjusted back to the normal curve, the blood flow is restored and problems (such as headaches) can go away. I saw an elementary school child come in, dragging his feet, and on crutches. After seeing his X-rays, and even my untrained eye could note the misalignment resulting from a fall, he WALKED out of our office (no crutches!) after treatment! Amazing. Don’t be so quick to say Chiropractic is not real. It is!
