New Study shows how Chiropractic can Help with Tension Headaches

Forward Head Posture, Cervicogenic Headache, and Anatomical Connection Found Between the Rectus Capitis Posterior Major and the Dura Mater

by Dr. Stephanie Maj

A new study, just published in Spine Journal, reports on an investigation of the muscles of the suboccipital triangle and their relationship to cervicogenic headaches (headaches that are caused by subluxations in the neck.)

This got me thinking of a problem I see in over 75% of patients that come to my office:  Forward head posture.  This position (see picture) puts the neck in an extended position which puts pressure on the nerves that go to the muscles in the back of neck, right under the skull (the rectus capitus muscle group).

This study reports that those muscles connect to the dura mater. The dura mater is the outermost, toughest, and most fibrous of the three membranes, or meninges, covering the brain and spinal cord.

During the anatomic study of thirteen cadaver specimens, it was discovered that eleven of the 13 specimens had a connection between the rectus capitis posterior major muscle (at C2) and the spinal dura mater. [1]  A previous report by Hack (Spine 1995) [2] discussed a connection found between the rectus capitis posterior minor and the dura mater and its relationship to cervicogenic headache.

What is most interesting in this new study is that manual traction of the rectus capitis posterior major resulted in gross movement of the dural sheath from the spinal root level at C2, all the way down to the T1 nerve root.  Hack previously suggested that:

“It has been speculated that the function of the muscle dural bridge may be to prevent folding of the dura mater during hyperextension of the neck. Also, clinical evidence suggests that the muscle dural bridge may play an important role the pathogenesis of the cervicogenic headaches.”

The authors of the current study concluded that “various clinical manifestations may be linked to this anatomical relationship.”  This is where Chiropractic comes in and the stress put on these upper neck structures from forward head posture becomes an important thing to evaluate.

According to Kapandji (Physiology of the Joints, Volume III), for every inch your head moves forwards, it gains 10 pounds in weight, as far as the muscles in your upper back and neck are concerned. That’s because because they have to work that much harder to keep the head (chin) from crashing onto your chest. This abnormal positioning also forces the suboccipital muscles (the ones that raise the chin) to remain in constant contraction, putting pressure on the 3 suboccipital nerves.

This nerve compression may cause headaches at the base of the skull. Pressure on the suboccipital nerves can also mimic sinus (frontal) headaches. It is these nerves and muscles that have the relationship with the dura mater and therefore the brain and headaches.

If you are suffering from headaches of any kind, take a look at how far your head is in front of your shoulders (they should line up ear over top of shoulder.)  Chiropractic has great success correcting this postural abnormality and when corrected, can lead to less pressure on upper neck and significant reduction of headaches.

Why Grains Are Not The Best For Us

As you probably know, we’ve been eating grains, refined or whole, only since the beginning of agriculture some 10, 000 years ago. The problem is that our genes where formed about 2 million years ago and haven’t changed much since then, nor did our digestive systems. Eating structurally and chemically different foods is therefore more often than not asking for problems. Grains are miles away from what our bodies should be processing.
In fact, grains aren’t really a good thing for any mammal. We’re better off leaving them to the birds, who have a system adapted to them.
The problem is that our food system is so skewed in the wrong direction that everybody now thinks that grains, especially whole grains, are healthy and nutritious. Grains, a food group that we didn’t eat for 97% of our human existence are now at the bottom of the USDA food pyramid with a recommended 6 to 11 servings per day. This is amazingly wrong!
Be aware that the reason why governments pushed grains in the first place where economical. They are cheap to produce (although not without environmental costs), they can be stored for much longer and they can be sold overseas much more easily. In fact, it’s now one of the few things that the US successfully sells overseas, so I wouldn’t count on them to stop promoting them as the healthiest thing around. Sad but true!

Ten reasons to limit fructose consumption.

10 reasons to limit fructose consumption

1. Fructose can only be metabolized by the liver and can’t be used for energy by your body’s cells. It’s therefore not only completely useless for the body, but is also a toxin in high enough amount because the job of the liver is to get rid of it, mainly by transforming it into fat and sending that fat to our fat cells.
2. Excess fructose damages the liver and leads to insulin resistance in the liver as well as fatty liver disease. In fact, fructose has the same effects on the liver as alcohol (ethanol), which is already well known as a liver toxin.
3. Fructose reacts with proteins and polyunsaturated fats in our bodies 7 times more than glucose. This reaction creates AGEs (Advanced glycation end-products), which are compounds that create oxidative damage in our cells and ultimately lead or contribute to inflammation and a host of chronic diseases.
4. Fructose increases uric acid production, which, in excess, can cause gout, kidney stones and precipitate or aggravate hypertension.
5. While most of your body’s cells can’t use fructose as a source of energy, the bacteria in your gut can and excess fructose can create gut flora imbalances, promote bacterial overgrowth and promote the growth of pathogenic bacteria.
6. In part because of the damage done to the liver, chronic excess fructose causes dyslipidemia, which means that your blood lipid markers tend to shift towards numbers that indicate a risk for heart disease.
7. Fructose rapidly causes leptin resistance. Leptin is a hormone that controls appetite and metabolism to maintain a normal weight. Leptin resistant people tend to gain fat and become obese really easily.
8. Excess fructose alone can cause all the problems associated with the metabolic syndrome (diabetes, obesity, heart disease, …).
9. Cancer cells thrive and proliferate very well with fructose as their energy source.
10. Excess fructose also affects brain functioning, especially as it relates to appetite regulation. It has also been shown to impair memory in rats.

Should I worry about my doctor taking too many x-rays?

On "Phantom Risks" Associated with Diagnostic Ionizing Radiation: Evidence in Support of Revising Radiography Standards and Regulations in Chiropractic   Paul Oakley, DC, MSc, Don Harrison, PhD, DC, MSE, Deed Harrison, DC, Jason Haas, DC


X-ray has been around since 1895, which is the same year that chiropractic was founded. CBP protocols require that the doctor must measure the displacements on spinal radiographs (segmental Subluxation). Both lateral-side view and anterior to posterior (AP) or frontal view CBP x-ray line drawing procedures have been studied and found to be reliable.^32-36Furthermore, CBP utilizes standardized x-ray positioning procedures that have been studied and found to be reliable.³⁶  
As with measures of pain intensity, range of motion, and quality of life, periodic assessment of spinal structural alignment is important to evaluate progress and determine when maximum patient improvement has been reached. In CBP Technique, the use of initial and follow-up spinal x-rays or radiographs is deemed necessary; however, some in chiropractic have condemned the use of follow-radiographs to collect alignment data.^37-39 Importantly, there is data to show that the use of medical/chiropractic x-rays constitutes a very minor health risk and in fact has been shown to be of benefit (decreased sickness and cancer mortality rates) in some studies.^40-42

Clinical Biomechanics of Posture

Clinical Biomechanics of Posture (CBP) is a chiropractic technique that deals with restoring spinal curves back to normal, or as near to the normal Harrison spinal model as possible. It has been proven that abnormal posture leads to spinal degeneration and ultimately ill health. CBP works by using specific adjustments with spinal corrective exercises in an effort to restore normal spinal alignment. X-rays are taken before a care plan is started, during the care plan if necessary, and at the end of a care plan in an effort to visualize how the spine is being corrected.
