The Spine and Lower Back Pain

I earn a small commission via affilate links at no extra cost to you.

If you’ve ever read Daniel Lieberman’s book The Story of the Human Body: Evolution, Health, and Disease you’d see that hunter gatherers had it pretty good. Sure people talk poorly about hunter gatherers and the paleo world because the average age of death was about 30 years of age due to a high infant mortality rate. Other than that they mostly died from injuries or infections (things we could easily cure or fix today), not chronic disease. People who have studied modern day hunter gatherers don’t find much lower back pain in these populations. In fact, the less you use your spine the more likely you are to have problems with it. This quote was taken from page 341 of Lieberman’s book:

A normal, fit back needs to have a considerable degree of flexibility, strength, and endurance, as well as some degree of coordination and balance. Since people who are mostly sitters tend to have weak and inflexible backs, they are more likely to experience muscle strains, torn ligaments, stressed joints, bulging disks, and other causes of pain if and when they subject their backs to unusual, stressful movements.

On of my biggest pet peeves is when people buy into the idea that they are hopeless, nothing can be done, it’s genetic, and they are destined to suffer for the rest of their lives. What happens to your body when you break a bone or cut your skin? It heals itself. If you donate a kidney the body knows to increase the function of the remaining kidney. If you slightly sprain (grade 1) a joint the body will send white blood cells and nutrients to the area to repair the tissues. Yes there are cases where some things are irreversible but I don’t understand the people who accept defeat without trying. Give your body the nutrients it needs and gradually work on becoming stronger and the human body will help you out the best that it can.

As a massage therapist specializing in myoskeletal alignment I can vouch that everyone I’ve worked on with lower back pain has / had a muscular imbalance. Most of the asymmetry occurs in the hips and the legs. If the lower back is sitting on crooked hips and legs how can it be happy? It won’t.

The Spine4 Spinal Curves

The spine is made of 33 vertebrae separated by 23 intervertebral disks. Vertebrae are named according to their location. Cervical vertebrae are located in the neck, Thoracic vertebrae attach to the ribs, and Lumbar vertebrae are found in the lower back just above the sacrum. There are 7 cervical vertebrae, 12 thoracic, and 5 lumbar. A simple saying will help you remember how many are in each region. “Breakfast at 7, Lunch at 12, Dinner at 5.” Those who have already done the math recognize 7 + 12 + 5 = 24. The sacrum, just below the lumbar vertebrae, and the coccyx, or tailbone, become fused as we age. Originally the sacrum is comprised of 5 bones and the coccyx 4, hence 24 + 9 = 33.

When we are born our spine has 1 curve. Learning to lift our heads and crawl we begin to develop the anterior curve of the cervical spine. As we begin to stand and walk the anterior lumbar curve develops. The curves of the spine are very important. A curved spine can support 10 times more weight than a straight spine.1

Vertebral Movement

Facet Joints

The vertebral disks act as natural shock absorbers and provide space between the vertebrae. Looking at the image below you will see a few things. Notice that when the top vertebrae moves forward the disk below it moves to the back. The opposite is true when the top vertebrae moves back the disk material is pushed forward. Also notice the facet joints highlighted by the black arrows. These are smooth bony surfaces that glide over each other during spinal movement. If a disk is compressed the distance between the vertebrae is reduced and the facet joints will have limited mobility, especially on extension, or bending backwards.

In the figure below notice the hole just in front of the facet joint. This is where the spinal nerves branch out from the spinal cord. If the vertebrae are not aligned properly the spinal nerve  gets pinched or squeezed on one side or both. Not only do these nerves control muscles they also ensure proper functioning of organs.

Spinal Nerves and Organs

Back in the 1920s, Dr. Windsor, a doctor of medicine from the University of Pennsylvania, was interested to find out if there was a correlation between curvatures in the spinal column (meaning, bones in the spine out of place) and diseased organs. To investigate this theory, Dr. Windsor examined fifty cadavers from the pathology department to search for unhealthy organs. In the fifty cadavers, he uncovered 139 infected
organs, such as hearts, livers and gall bladders, in different phases of sickness. Next, Dr. Windsor studied the nerves from the affected organs and traced them back to the spine.

The discovery by Dr. Windsor was amazing! In all of the cadavers, there existed a misalignment of the curvature in the spine, which was directly connected to the nerves leading to the unhealthy organs.

From top to bottom different regions of the spine control different organs. These nerves are part of the autonomic nervous system, the “automatic” nervous system. The signals they send to the brain and spinal cord, the central nervous system (CNS), are interpreted. When the information is processed the CNS sends a message back to the organs resulting in a metabolic change. So, if the spinal nerves are pinched the communication between the organs and CNS is diminished. Typically people associate pinched nerves with excruciating pain. In many cases that is true, but there are varying degrees of nerve compression. A nerve can be slightly compressed and not produce any pain symptoms. 

Mechanics of The Lumbar Spine

The video below gives a great explanation of spinal anatomy and how the pieces move together.

Lower Back Pain

Lordosis

At any given time 2-5% of the world’s population suffers from lower back pain. 2 In some cases the pain is only musculoskeletal. In these instances the bones and muscles are out of proper alignment so they have to work harder than normal. There is a phenomena in the body called the pain-spasm-pain cycle. It works as a protective mechanism, but if it is not addressed it leads to further problems. Whenever an area of the body is injured or in pain the body will tighten the muscles in that area to prevent further damage. Although this helps reduce the pain, the tight area begins to affect surrounding muscles and tissues not originally involved.

Bulging and Herniated Disks

More serious forms of back pain include bulging and herniated disks. Remember how the disk material moves posteriorly, towards the back of the body, when the spine bends forward? This is why lifting with your legs instead of your back is so important. A disk that is bulging or herniated posteriorly can press on the spinal nerves and or the spinal cord.

A disk that presses on a spinal nerve between the 4th and 5th lumbar vertebrae can cause sciatica. Symptoms of sciatica include pain in the lower back, weakness in the legs, and pain and tingling down the leg.

However, the symptoms of sciatica can also be caused by gluteal muscles. Specifically, the piriformis muscle. For some of the population, the sciatic nerve runs under the muscle and in others the nerve runs through the belly of the muscle. Genetics determine where the nerve is located in relation to the muscle. This is one of the reasons why gluteal massage is so important for back health. The forces generated by every step we take are transferred through the pelvis to the back. If the pelvis and legs aren’t happy it is almost impossible for the back to be happy. Without a proper foundation muscle asymmetries will develop leading to back pain.

Muscle Asymmetries of Lordosis

Lower Cross Syndrome

When the muscles of the lower body create an anteriorly tilted pelvis it is referred to as the lower cross syndrome. Drawing an imaginary line from the weakened gluteals to the weakened abdominals creates half of the cross. Connecting the shortened iliopsoas with the shortened erector spinae makes the other half of the cross. This is a very common muscle imbalance that is the source of most back pain. Many people view their body as separate parts which are not related to anything else. In the case of lower back pain it does not occur to most of us that our stomach is the front of the lower back. Pregnant women are the perfect example of this muscle asymmetry and lower back pain. Not only does the weight of the baby pull the spine forward the abdominal muscles also become stretched and weakened. Since there aren’t many people over 25 with abdominals toned to a six-pack it is easy to understand why so many suffer from lower back pain.

30 Day Wellness Journal

If we could travel back in time I’m sure we would notice that cavemen didn’t sit behind desks 40 hours a week. Our brains continuously monitor muscle tension. While sitting for extended periods of time the brain detects too much slack in the quadriceps, front of the thigh, muscles. When the front of the thigh muscles are short and tight they pull the pelvis down in the front. This causes the back of the pelvis to move up towards the spine creating lordosis. One would think that if the pelvis is tilted forward then the upper body should tilt forward as well. Looking around it is pretty rare to see people walking around bent forward at the waist. The brain also works to keep the eyes level with the horizon. So as the pelvis is tilted forward the brain shortens the muscles in the lower back to bring the torso upright.

Restoring Balance

If you have been diagnosed with lordosis there are a few steps you can take to help prevent further low back pain. Strengthening the weak abdominal, gluteal, and hamstring (back of the thigh) will help even out muscle asymmetries.

Massage can also be an excellent tool to aid in lengthening the shortened quadriceps and lower back muscles. As the shortened muscles are lengthened the pelvis can begin to rotate posteriorly. Look for a therapist who performs myoskeletal alignment. This is something I specialize in and the course work covers muscle imbalances, fascia and working with chiropractic care providers. If you can’t find an alignment therapist look for a local massage therapist either through AMTA or ABMP who specializes in myofascial release. Myofascial release is a gentle technique that addresses the connective tissue, fascia, of the muscles. Fascia can be thought of as pantyhose surrounding a muscle. If the pantyhose are pulled tight it is nearly impossible for the muscle to occupy its optimal form and function.

Chiropractic work can also aid in proper spinal alignment. In my professional experience chiropractic and massage therapy work very well together. Since the muscles hold the bones in place, chiropractic adjustments are usually more productive after the muscles and fascia have been released.

At Home Remedies

Yin Yoga

Yin Yoga is unlike most type of yoga because the focus is on limited muscular effort in order to focus on the joints. Basically you lie on the floor in different positions stretching your connective tissue; it’s like giving yourself a massage. I a set by Paul Grilley and I love that it includes Yin exercises focused on the legs and spine, Yang exercises (traditional yoga), and a 45 minute lecture on the thinking behind Yin vs Yang Yoga.

Foam Rolling 

A foam roller is great for working out your overly tightened quadriceps on the front of your thigh. I will tell you though to go easy at first. There are some places in my thighs that are pretty tender so if you have these go slowly and don’t force it. When you force massage you activate the stretch receptors and cause the muscle to tighten further. Instead, move slowly on the roller and wait for the tissues to soften before moving on to more tender areas. Revisit the muscle roller every few days at first and if you experience any muscle soreness (an indication that you may have worked the muscle too hard) wait for that to subside before rolling again. Try to avoid rolling your muscles while taking pain medications because they will dull your sensation and may lead you to work deeper than you should. If you have a history of blood clots or suspect that you have them contact your physician before getting massage.
