Core Stabilization – Foundation of a Healthy Lower Back




  We often hear our doctors, therapists and trainers discuss core stabilization and how integral it is for the function and health of our bodies, especially for our lower backs. But what is it? And why is it considered so important?

  Core stabilization refers to your ability to keep your core structure (torso, abdomen and spine) relatively stable as the appendicular skeleton (legs, arms and connecting structures) is recruited to do physical work like walking, running, throwing and lifting.

  Consider what would happen if you did not possess core stability. Every time you wanted to move – bringing either an arm or a leg away from your midline to perform a task – your body would be pulled in that direction and you would fall over. If you did not fall, you would most likely strain the holding elements of your joints (i.e. the ligaments) instead, once the load became too great. Not a good scenario.




What are the essential components of core stability?
  When most of us think of the core muscles, an image of a bodybuilder’s six-pack abs (the rectus abdominis) usually comes to mind. Actually, this abdominal muscle is the one contributing the least to core stability! Instead of acting as a stabilizer, the primary role of this muscle is to movethe torso into flexion (i.e. curling up into a ball).




  The deepest abdominal muscle layer is the transversus abdominus, and it is the prime stabilizer of the torso, aided by several other specific support muscles (the internal obliques and the multifidus).  Scientific studies show that before any movement is initiated, these muscles are engaged beforehand, and the transversus abdominis muscles are always recruited first.

  If you think of a girdle or corset – those ladies’ garments often worn to cinch the waist and give that hourglass appearance – this would give you a good idea what the transversus abdominis muscle does for the body. When it contracts, this muscle squeezes and holds the trunk and torso quite rigid and allows for the arms or legs to do their job without pulling the body this way and that. You may be familiar with the competitive powerlifter’s thick leather belt - compressing and holding the lower back steady while the rest of the body prepares to lift, clean and jerk up to a thousand pounds overhead. Although this is an extreme example, the function is the same.




What happens when these core muscles don’t function properly?
  Research reveals patients with lower back pain have delayed or insufficient firing patterns of the transversus abdominis muscles compared to control groups with no back pain.2,3 Although researchers admit it does not prove this muscle delay causes lower back pain, their findings clearly identify a relationship between core stabilization and lumbar spine symptoms. Results from these studies show that by increasing the activation of the core stabilizers, primarily the transversus abdominis, back pain may be reduced or prevented.
Does increasing core stability actually help your lower back
  Recent evidence suggests that it does. Researchers took a group of 39 patients who experienced an initial episode of  acute low back pain and then divided them into two groups: one that was given specific strengthening exercises for the transversus abdominis and multifidus muscles, and another group that did not do these exercises.

  Follow-ups with these two groups of patients one year and three years later revealed a significant difference between the two. In the group that was given the specific core strengthening exercises, there was a 30-35% recurrence rate of symptoms. Whereas in the other group that did not perform the exercises, there was a 75-85% recurrence rate of lower back pain.4
  Although a consultation with your chiropractor is your best bet for a speedy recovery from acute low back pain, it looks like an abdominal contraction-a-day can really help keep the long-term pain away!

Pregnancy and Low Back Pain

  Pregnancy is a unique and challenging condition – for both the female who is pregnant and for her chiropractor! The effects of major hormonal shifts, an incredibly rapid weight gain (and then loss), and the stress associated with being a new mother all combine to make pregnancy one of the most common causes of low back pain. The Stats   Low back pain statistics for pregnant females are quite alarming. For the general population, it is estimated that approximately 70-85% of us will experience at least one bout of acute low back pain in our lives. 1   In the pregnant female population, the rate is 50-80% during a 9-month window! And for those women who experienced back pain during pregnancy, over 60% of these women described the pain as at least moderately severe, and close to 10% said the pain was “completely disabling.” 3 The Main Cause of Pain   Since low back pain often occurs in the later stages of pregnancy, experts suggest that the main cause of thi...

What You May Not Know About Fiber

We have heard a lot about how we should get plenty of fiber in our diet. It is good for us, right? But what exactly is fiber and why does it aid our health? What is the difference between soluble fiber and insoluble fiber? Is one better than the other? What foods are the best sources of fiber? And how much do we need each day? In this issue of Wellness Express™, we look more closely at fiber, the different types, and the research that supports its remarkable health benefits. Fiber 101 What exactly is fiber? It is a food substance, predominantly found in plants, that cannot be digested by humans. Most fiber materials would be classified as complex carbohydrates. Because it cannot be broken down and absorbed into our bloodstream, fiber moves through our intestines, helping to remove waste and toxins, before being excreted. Dietary fiber refers to foods with naturally occurring fiber. Functional fiber is fiber added to a food product to boost its content of this substance. Solu...

Can Chiropractic Improve Your Game?

Athletes place a high physical demand on their bodies. They ask the body to work like a finely tuned, well-oiled machine. The rigorous training and competition schedules leave little time for injuries. Perhaps this is why almost every professional team in sports has a chiropractor looking after its athletes. As an example, 95% of NFL teams will employ chiropractors regularly to treat their players.1 Professional sport involves a combination of: coordination, balance, strength and flexibility. To reach the pinnacle of achievement in any sport, requires split-second reflexes, peak structural strength and stability and a will and determination to keep going when the going gets really, really tough. It requires a body that is functioning at its highest capacity. How Does This Relate to Chiropractic? Chiropractic is a healing art that focuses its attention on the function of the spine, and the precious nerve tissue (the spinal cord) that is encased in it. When it is aligned properly, ...
