Chiropractic + Naturopathic Doctor • April 2020 • Low Back Pain, Revisited

It's been referred to as the scourge of modern man. The age-old affliction of low back pain has likely been with us since we achieved the upright posture. Over the millennia, healers and practitioners of all stripes have grappled with this challenging condition… stretching, pummeling, cracking and even hacking, in order to alleviate the pain and discomfort of this often debilitating condition. The challenge of course, is that most of the approaches used throughout the health care system, have failed to provide long-term solutions.

In this article, I would like to present some revolutionary concepts, which may help to explain some of the underlying causes of low back pain, and by extension, many other painful biomechanical disorders. I hope to shed light on why some of the approaches, currently in use, may be helping… or not. This information is based on some of the latest scientific evidence of how the body is constructed at the cellular and molecular level. I believe a better understanding of how the body responds to injury, at the most fundamental level, may provide us with the insights necessary to provide real and lasting solutions.

I often begin my presentations to practitioners and the public with the following request: “Put up your hand, if you’ve NEVER had a fall.” So far, no takers.

Walking the earth on two legs has provided us with tremendous advantages: freeing the upper extremities to be able to manipulate the environment (gather food, wield tools and weapons), presenting a higher profile to deter predators, and the ability to survey our surroundings for potential threats and opportunities. However, one of the main trade-offs, is that the upright, bipedal posture has made us more vulnerable to the laws of physics; namely gravity, inertia and momentum.

As a result of this vulnerability, we begin the assault on our bodies at a fairly young age. From the moment we set forth on two toddling legs, this often takes the form of slipping and falling on the ground or the stairs, bumping into furniture, tripping over toys and bumping our heads on cupboards, door frames and our siblings. As we get older, we tend to engage in activities that put us at further risk for injury, such as high speed and contact sports, motor vehicle collisions, etc. The list goes on and on.

Simple physics tells us that a structure, which has a higher density, will absorb the force of an injury to a greater degree than another structure with a lower density. Therefore a more dense structure is inherently more vulnerable to the effects of injury. For example, if you strike a pillow with a hammer, there will be practically no sound and little or no evidence of the assault, given that the force is easily dissipated by the loosely arranged structural elements of the filling material. In contrast, striking a piece of wood, such as a table top, will make a lot of noise, since the more closely- packed molecules will bounce off of each other, setting the surrounding air molecules in motion, which cause the ear drum to vibrate more vigorously. As a result of its greater density, the wood will clearly and permanently demonstrate the effects of the ‘injury’.

One of the densest substances in the body is bone, which is a form of mineralized fascia. In previous articles, I presented evidence that bone expands with injury (Figure 1) 5. My theory is that these changes in bone size, especially in the spinal area, might appear as misalignment (subluxation), when in fact, the evidence suggests that this is most likely due to asymmetrical enlargement of the one portion of a vertebral segment or segments. Radiological and anatomical investigation appears to support this contention. To verify this for yourself, measure the width of your own knees (the distal femoral condyles and the patella), or observe these differences with your patients. I have also pointed out that a tissue injury in one area is transmitted throughout the body, via the extracellular matrix (ECM). Thus, the area of symptoms may remain elusive, unless we have a way to detect the actual source(s) of tissue injury. Fortunately, we have discovered a method to detect these underlying injuries (Primary Restrictions) due to changes in their bio-electric properties.

In a previous article (Solutions for Low Back Pain and Instability, February 2017), I referred to the Articular Stability Reflex (ASR), a mechanism I discovered in the mid 1990’s, which appears to explain how the loss of stability in certain joints, may contribute to the development of pain and articular degeneration. Muscles, which provide dynamic stabilization, such as the popliteus and medial hamstrings (knee), supraspinatus (shoulder), gluteus medius (hip), tibialis anterior (ankle) and multifidus and rotatores (lower lumbar spine), are literally turned off, in response to certain injuries. I speculated that this mechanism would have the effect of mitigating the transfer of additional strain to core structures, including the spinal cord, by creating a ‘wobble zone’ in these peripheral joints, which I refer to as sacrificial joints. It is important to note that the spinal cord is not present in the lower lumbar spine, which might explain why it is also sacrificed, so to speak.

Programs to develop ‘core strength’ have been promoted to counteract this response, however, it is my contention that it is not possible to strengthen these particular muscles, as they are essentially denervated, i.e. turned off. This would be like repeatedly changing the light bulb in a lamp that is not plugged in, in an attempt to make it work.

The resultant instability may play a role in the degeneration of those structures, by increasing mechanical stress on articular cartilage, menisci, subtending bone and the intervertebral disc, in the case of the lower lumbar spine. These observations have been validated by recent evidence1-4. Our experience has demonstrated that treatment of the underlying structures, which initiate the ASR, tend to immediately re-establish normal tone and function of the stabilizing muscles, literally restoring joint stability, like turning on a light switch.

In the illustrations below, the diagram on the left (Figure 2) represents the ideal structural balance of the skeletal components of the lower quadrant and normal tone of the stabilizing elements of the spine (intrinsic intervertebral musculature). The diagram on the right (Figure 3), illustrates several structural imbalances, including relative enlargement of the right femur and innominate, ipsilateral enlargement of the right side of the sacrum, L4, 5, and depression of the right lower ribs along with ipsilateral enlargement of the associated vertebra. These injuries are commonly observed subsequent to a fall on the side. This will typically result in hypertonicity of several myofascial elements, including the iliopsoas, quadratus lumborum, gluteus and the iliotibial band. By contrast, the lower lumbar paraspinal intrinsic muscles (dynamic stabilizers) tend to become relatively hypotonic, as part of the Articular Stability Reflex response (see above).

These, and many other common injuries, are often associated with similar structural and functional changes. Once these imbalances develop, the mechanical stress imposed on the lower lumbar discs and other articular elements, begin their chronic, degenerative decline towards annular deterioration, inflammation, arthrosis, stenosis and their associated neurological consequences.

Our assumptions as to the causes of many structural conditions, including low back pain, may need to be revisited in light of new revelations about the underlying structure of the body and how it responds to injury at the most fundamental level. Our understanding of the consequences of physical trauma, in the form of impact or strain, has evolved significantly in the past fifty years and it is essential that we adapt our clinical interventions to incorporate these discoveries. We owe it to ourselves and to our patients, to strive to achieve the lasting and profound solutions that are now within our grasp.
