The basic hypothesis of Thomas Myers’ writings on Fascia kinetic lines is that muscles, no matter what they do individually, also affect tissues throughout the entire body through Fascia based interconnections. These interconnections can be called Fascia lines and can be followed by the body’s dissectible “meridians” of connective tissue structures. They consist of membranes and ligaments, both superficial and deep connective tissue, loose and tight. These Fascia lines create stability, resistance, power, flexibility, elasticity, and above all- compensatory posture. So connective tissue structures work in sync, creating a fluid and balanced movement and a posture that maintains balance and direct contact between all body parts.
In Myers book “Anatomy Trains” ligaments are described as the “inner bag” and outside them are Fascia based pathways, lines, interconnected longitudinal structures that distribute power and compensation. The map of Fascia lines shows the longitudinal bands and loops of connective tissue including muscles and organs, which is based on the relatively new anatomical knowledge and analysis of how the musculoskeletal system really works. The old view of muscles, the theory of “isolated muscle function” is that muscles work only position against the origin and mostly contracts and resists. If we add on the knowledge of the Fascia’s power transmitting function, the picture is much more detailed. All tissue in the body is naturally linked to the network that the Fascia forms, but these lines are more clearly distinguishable from other tissue and appears to transmit signals / operating with more power through these pathways. The Fascia consists of many types of collagen, elastin, retinacula fibers, and the sticky proteins called “basal lamina” or also known as the extra-cellular matrix. In this basic substance nutrient exchange and communication between cells and body parts can occur.
You can see that in parts of the body that are blocked, where muscles are locked in either a static mode, or short locked mode and skeletal parts have gotten out of position. Then, the extra-cellular matrix (basal lamina) is thinned and membranes stick together. The collagen fibers of the Fascia builds up and becomes more stiff and locked from overload / poor mobility. As this occurs, and the basal lamina is also diluted the cells in the area does not get enough nutrition and hydration, and a vicious circle and state of illness is initiated.
