Surface Electromyography (sEMG) is a fast, non-invasive, and painless technique we use in the office to measure and visualize the tension in the muscles on either side of your spine. This gives us a way todetermine what’s going on with your nervous system, and to chart your progress under care.
In a normal, healthy patient scan (pictured left) the tension is both at a normal amount, and is symmetrical on either side of the spine. In an abnormal, unhealthy patient scan the amount of tension is either too high or too low and is substantially different from right to left.
Too much tension and asymmetrical tension can mean that the nervous system is stuck in a pattern of “fight or flight.” This is a sign that the body is in what we call Defense Posture and Defense Physiology. Instead of being able to release tension and postural distortions at rest, the nervous system continues to react as though danger is imminent.
In Level 1 NSA care our goal is go help the body connect with and release it’s patterns of defense, thus liberating the energy being used to store tensionfor healing.
Your brain, and the nerves that leave your brain through the spinal cord and go out to the muscles and organs of your body, have a special job to do in stabilizing the spine. The spine must be protected through proper muscle tension, but it must also have proper flexibility and movement to flexible to fully experiencing all that life throws our way.
If the brain is not doing a good job stabilizing the spine and allowing ease in the body, our ability to adapt and meet the challenges of the day are compromised.
The first changes we look for in the myovision scan usually take place within the first 2-3 months of care. First, we look for evidence that the brain is changing the pattern of tension being held in the body. Even if tension still remains high, changes in how and where the tension is held demonstrate that nervous system is responding to care on a deeper level and attempting to reorganize.
Next we look for decreases in tension in areas where there was too much, and increases where there was not enough. How could there be too little tension? In the scan on the right, you’ll notice some areas with yellow bars. These tell us that that the system isn’t doing enough to stabilize these areas through the muscular system. This is in contrast to other levels of the spine, where the nervous system is going overboard to stabilize the spine. We want all levels properly stabilized, at ease, and working together.
sEMG helps us determine what’s happening in your system, and show you when and how your system changes with care.
