Fascia is very dense covering, interpenetrating every muscle, bone, nerve, artery and vein as well as all of our internal organs including the heart, lungs, brain and spinal cord. The most interesting aspect of the fascial system is that it is not just a system of separate coverings. It is actually one structure that exists from head to foot without interruption. In this way you can begin to see that each part of the entire body is connected to every other part by the fascia, like the yarn in a sweater.
In the normal healthy state, the fascia is relaxed and wavy in configuration. It has the ability to stretch and move without restriction. When we experience physical trauma, scarring, or inflammation, however, the fascia loses its pliability. It becomes tight, restricted and a source of tension to the rest of the body. Trauma, such as a fall, whiplash, surgery or just habitual poor posture over time and repetitive stress injuries has a cumulative effects. The changes they cause in the fascial system influence comfort and the functioning of our body. The fascia can exert excessive pressure producing pain or restriction of motion. They affect our flexibility and stability, and are a determining factor in our ability to withstand stress and strain.***Since many of the standard tests such as x-rays, myelograms, CAT scans, electromyography, etc, do not show the fascial restrictions, it is thought that an extremely high percentage of people suffering with pain and/or lack of motion may be having fascial problems, but most go undiagnosed.
