According to the Fascia Research Congress, fascia is the soft tissue component of the connective tissue system that permeates the human body. It forms a whole-body continuous three-dimensional matrix of structural support. Fascia interpenetrates and surrounds all organs, muscles, bones and nerve fibers, creating a unique environment for body systems functioning. The scope of our definition of and interest in fascia extends to all fibrous connective tissues, including aponeuroses, ligaments, tendons, retinaculae, joint capsules, organ and vessel tunics, the epineurium, the meninges, the periostea, and all the endomysial and intermuscular fibers of the myofasciae.
There is a substantial body of research on connective tissue generally focused on specialized genetic and molecular aspects of the extracellular matrix. However, the study of fascia and its function as an organ of support has been largely neglected and overlooked for many years. Since fascia serves both global, generalized functions and local, specialized functions, it is a substrate that crosses several scientific, medical, and therapeutic disciplines, both in conventional and complementary/alternative modalities.
Among the different kinds of tissues that are involved in musculoskeletal dynamics, fascia has received comparatively little scientific attention. Fascia, or dense fibrous connective tissues, nevertheless potentially plays a major and still poorly understood role in joint stability, in general movement coordination, as well as in back pain and many other pathologies. One reason why fascia has not received adequate scientific attention in the past decades is that this tissue is so pervasive and interconnected that it easily frustrates the common ambition of researchers to divide it into a discrete number of subunits, which can be classified and separately described. In anatomic displays, fascia is generally removed, so the viewer can see the organs nerves and vessels but fails to appreciate the fascia, which connects and separates these structures.
