Fascia is a structure of collagen, elastin and water that surrounds muscles, groups of muscles, blood vessels, and nerves. Various kinds of fascia may be distinguished and are classified according to their layers, functions and anatomical location. Fascia can bind some structures together while permitting others to slide smoothly over each other.
Fascia is similar to ligaments and tendons, being made of collagen but the functions are different. Ligaments join bone to bone, tendons join muscle to bone, fascia surrounds everything in the body, organs, muscles, nerves, blood vessels etc..
Fascia is dense regular connective tissue, containing closely packed bundles of collagen fibres arranged multi-directionally in layers. The fascia is a flexible structure able to resist great tension forces in a multitude of directions.
As muscles move and stretch so does the fascia, the fascia enhances the muscle’s actions and recruits other muscles to assist the movement. Anything that resticts the movement of the fascia has a direct affect on a muscle's efficency and hence movement.
Myofascial release is a technique to stretch and “de-knot” the fascia to enable more efficient body movements.
Sissel Myofascia tools are designed to assist in stretching and "de-knotting" the fascia. The "knots" appear as tight or painful points in the muscle and restrict the efficiency of the muscle and fascia.
