Why Chiropractic?

People often know what chiropractors do: they adjust joints, work on muscles, and treat neck and back pain. A more important question is: why should someone choose chiropractic care in the first place?

The answer is not that every painful joint is “out of alignment,” that everyone needs regular adjustments, or that manipulating the spine somehow treats every health problem.

The more practical reason is simpler: many common musculoskeletal problems can be managed conservatively, without medication, injections, or surgery, and chiropractic care is one option for doing that.

For the right patient, a chiropractor can evaluate the problem, determine whether it appears appropriate for conservative treatment, provide manual treatment when indicated, recommend appropriate activity or exercises, monitor the response, and refer for to a different provider for additional evaluation when necessary. That is where chiropractic makes the most sense.

Start With the Diagnosis, Not the Adjustment

A chiropractic visit should not begin with the assumption that every patient needs to be adjusted.

Back pain, neck pain, headaches, arm or leg symptoms, and joint pain can have many causes. Most are musculoskeletal and relatively benign, but occasionally symptoms can indicate something requiring imaging, medication, specialist evaluation, or urgent medical treatment.

The first job of the chiropractor is therefore not to find something to adjust. It is to determine what is most likely causing the patient's symptoms and whether chiropractic treatment is appropriate.

That requires a history and examination. Depending on the problem, the chiropractor may evaluate:

• joint movement and restriction;
• muscles, tendons, and other soft tissues;
• strength, sensation, and reflexes;
• orthopedic and neurologic findings;
• posture and movement patterns;
• previous injuries and medical conditions; and
• findings that might suggest a problem outside the musculoskeletal system.

Imaging may occasionally be necessary, but most patients with uncomplicated back or neck pain do not automatically need X-rays or an MRI before conservative treatment.

Why Try Conservative Care First?

Pain does not automatically mean that something needs surgery, an injection, or a prescription medication. For many common musculoskeletal conditions, modern treatment guidelines encourage beginning with conservative approaches (i.e. treatment without surgery or other more invasive procedures).

For chronic primary low-back pain, for example, the World Health Organization recommends an individualized combination of treatments that can include education, exercise, massage, and spinal manipulative therapy. The WHO includes spinal manipulation as one treatment that may be offered as part of an overall plan of care.

The National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health, also recognizes spinal manipulation as a noninvasive treatment option that may improve pain and function in patients with low-back pain.

For an appropriate patient, conservative care can reduce pain, improve movement, and help restore normal activity while avoiding or delaying more invasive treatment.

What Does an Adjustment Actually Do?

The traditional chiropractic explanation was that spinal bones could become displaced or “subluxated,” interfere with nerves, and cause disease throughout the body. Modern anatomy and research do not support that explanation in the way it was historically presented.

A chiropractic adjustment (i.e. spinal manipulation) is a controlled mechanical force applied to a joint. It can influence joint movement, muscle activity, sensory input from the area, and how the nervous system processes pain.

The familiar popping sound is generally caused by a pressure change within the joint. It does not mean a bone was put back into place. Likewise, a joint does not need to remain permanently “aligned” after treatment for an adjustment to be helpful.

A better way to think about manipulation is as one method of temporarily changing how a painful or restricted area moves and feels. That improvement may make it easier for the patient to walk, exercise, work, sleep, or resume normal activity. Improved daily function is ultimately much more important than whether a joint makes a popping sound.

What Problems Are Reasonable for a Chiropractor to Treat?

Chiropractic care is primarily most applicable to musculoskeletal problems. Common examples include:

Low-Back Pain

Low-back pain is one of the best-studied reasons people seek chiropractic care. Spinal manipulation does not cure every cause of back pain, but evidence suggests that it can produce improvements in pain and function in many patients. It is one of several conservative options available alongside exercise, education, physical therapy, massage, and other approaches.

Neck Pain

Patients with mechanical neck pain often respond well to manual therapy, including mobilization or manipulation, particularly when treatment is combined with appropriate activity and exercise. As with any treatment, appropriate patient selection is important, and not every cause of neck pain (e.g. fracture) is suitable for manipulation.

Certain Headaches

Not every headache comes from the neck. However, some headaches (particularly cervicogenic headaches) are associated with structures in the cervical spine. Research suggests spinal manipulation may provide a benefit for patients with cervicogenic headache.

Other Joint and Soft-Tissue Problems

Depending on training and state scope of practice, chiropractors may also evaluate and conservatively treat certain problems involving the shoulders, hips, ribs, knees, ankles, and other areas of the musculoskeletal system. In many of these cases, manipulation is only one possible treatment. Soft-tissue treatment, exercise, activity modification, or referral to another provider may be more appropriate.

Chiropractic Should Not Mean “Adjust Everything”

One area of discussion within chiropractic has been the idea that finding something slightly restricted automatically means that it needs treatment. Human joints are not perfectly symmetrical. X-rays are not perfectly symmetrical. Posture is not perfectly symmetrical. If nature produced perfect symmetry, our trees would look like illustrations from a Dr. Seuss book.

Asymmetrical findings do not necessarily represent disease. Asymmetrical or abnormal examination findings do not necessarily represent disease or identify the source of a patient's symptoms. The same principle applies to soft-tissue findings. Myofascial trigger points can be found in people who have no pain or functional limitation. Shah et al. noted that myofascial trigger points are commonly found in asymptomatic individuals, while a systematic review by Lluch et al. similarly found latent myofascial trigger points in asymptomatic people.

Treatment should be directed toward the patient's symptoms, examination findings, functional limitations, and response to care—not toward repeatedly correcting minor anatomical variations that may have little clinical importance.

Furthermore, the goal should not be to create dependence on treatment. If a patient improves and can resume normal activity, that is a successful outcome. There is no reason to continue treatment indefinitely simply because another adjustment can be performed.

What About a Long-Term “Maintenance” Schedule?

Some chiropractic offices recommend routine adjustments indefinitely—sometimes weekly, biweekly, or monthly—even after the original problem has resolved. That is NOT how we routinely approach care.

For most uncomplicated musculoskeletal problems, we prefer a short trial of treatment and then judge what happens. Most patients should show meaningful improvement within approximately four to six visits, and many improve sooner.

If the patient is improving, treatment can be reduced or discontinued as appropriate. If the patient is not improving as expected, simply performing more of the same treatment is not a satisfactory plan. The diagnosis and treatment strategy should be reconsidered, and imaging, another treatment approach, or referral may be appropriate.

The objective is not to see how long someone can remain a chiropractic patient. The objective is to help the patient recover.

Chiropractic Is One Part of Musculoskeletal Health Care

There is sometimes an artificial argument over whether someone should see a chiropractor, physical therapist, medical doctor, physiatrist, orthopedist, or another provider. In reality, those professions frequently address different portions of the same problem.

A patient with straightforward mechanical back pain may need nothing more than conservative treatment and continued activity. Another patient may benefit primarily from physical therapy. Someone with progressive neurologic deficits may need an MRI and surgical consultation. A patient with persistent radicular pain might ultimately benefit from a physiatrist, medication, or an injection.

And occasionally an examination reveals something that should not be treated with chiropractic care at all. Knowing when not to treat is as important as knowing how to perform treatment.

So, Why Chiropractic?

The best argument for chiropractic is not that adjustments cure disease or that everyone needs their spine routinely realigned. It is that chiropractors are trained to evaluate musculoskeletal complaints and can provide a low-risk, non-drug, nonsurgical treatment option for many common problems.

For an appropriate patient, treatment may reduce pain, improve movement, and help restore normal activity. For another patient, the most valuable thing the chiropractor may do is recognize that chiropractic treatment is not the right answer and make the appropriate referral.

Good chiropractic care should therefore be measured less by how many adjustments are performed and more by something much simpler: Is the patient getting better?
