Fascia is a band or sheet of connective tissue beneath the skin that attaches, stabilizes, encloses and separates muscles and internal organs. Fascia is classified by layer as superficial fascia or deep fascia and as visceral (parietal) fascia or by its function and location. As muscles move and stretch so does the fascia, the fascia enhances the muscle’s actions and recruits other muscles to assist the 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.
