STRUGGLING WITH LOW BACK PAIN?
A NEW STUDY SHEDS LIGHT ON CAUSES AND SOLUTIONS
"The role of the lumbodorsal fascia is generally neglected in spine biomechanics. Yet it is perhaps the most important structure insuring the integrity of the spinal machinery. The viscoelastic property of its collagen has a direct impact on the way the muscles are used and forces are channeled from the ground to the upper extremities. As a controller of the forces distribution between muscles and fascia, lordosis is the prime candidate for rehabilitation in the event of injury."
Let's take just a moment and talk about Gracovetsky's statement. In light of what we know about CHRONIC NECK PAIN and the relationship to loss of the neck's NORMAL LORDOTIC CURVE, it is highly intriguing that Gracovetsky is talking about the importance of the lordotic curve in the lumbar spine (low back) as well. In other words, whether you have no lordosis (a straight low back when looking from the side) or a hyperlordosis (a "sway back"), it is likely affecting the integrity of the fascia ---- even if you do not currently have pain. There is such a thing as "normal" structure (everyone is so different -- a great article on this subject is The Best Kept Secret: Why People HAVE to Squat Differently over at 'The Movement Fix'), and it is important to understand when we start looking at biomechanics. Let's see how much today's study agrees with this premise.
The very first thing the authors do is talk about ASYMPTOMATIC DISC HERNIATIONS as a proof that a significant portion of chronic back pain is not arising from spinal discs --- something that I have been talking about for at least 15 years. One of the coolest things they discussed was the fact that despite MRI not necessarily being a good method of imaging the low back --- particularly if the problem is fascia-related --- diagnostic ultrasound might be (HERE), as there is a definite visible difference in the shear between the three layers of the Thoracolumbar Fascia in people with low back pain versus people without (click the link as it will provide the most informative 30 seconds of your day).
First off, the term nociceptive afferents is referring to pain-sensitive sensory nerves (as opposed to PROPRIOCEPTIVE SENSORY NERVES). When the inflammatory "sensitzation" process becomes especially long-lasting and intense it can turn into CENTRAL SENSITIZATION, best explained by the pain getting locked into the brain and playing on a continual loop. Furthermore, irritation to the Thoracolumbar Nerves can come from several sources. It can be BOTH MECHANICAL AND / OR ELECTRICAL, or it can be CHEMICAL as well (yes, it's not only possible to have all three, it is fairly common). The finale of this study was the authors sharing something you already know if you have followed my blog --- spinal discs do not cause nearly as much pain as they are given credit for (HERE), as is also true with degenerative arthritis (HERE). So now that we know it's likely that a great deal of chronic low back pain is arising from the Thoracolumbar Fascia instead of a "bad" disc, what can be done to heal it and make it better? Glad you asked!
Firstly, read my article TELL ME AGAIN WHY YOU WANT AN MRI?. Then realize that while I could give you a whole new post on the subject, why reinvent the wheel? HERE is the post I give my patients who are wanting to begin solving their back problems on their own. Their goal is almost always the same. They don't want to live the rest of their lives on THE BIG FIVE, and if at all possible, to avoid spinal surgery (or another spinal surgery). Trust me when I tell you that it's much more than, "here, do the exercises on this sheet and come back for a weekly adjustment".
If you are one of the tens of millions of Americans dealing with chronic low back pain, this post could prove invaluable to you. If you agree, make sure to make sure those you love and care about most see this information as well. Best way to do this? FACEBOOK, of course.
