The body may develop scar tissue where a surgical incision is in the skin or if muscles and tendons were cut or repaired, Scar tissue is formed by collagen that your body lays down in a random fashion after an injury to become normal healthy tissue. (Normal healthy collagen is aligned in specific ways and directions that give your tissue strength.)
Cross friction or transverse friction massage involves using one or two fingers to massage your scar in a direction that is perpendicular to the line of the scar. This technique helps to remodel the scar and realigns the fibers. Myofascial release (MFR) is often used to manage scar tissue and related adhesions. The technique involves using the hands to massage the skin and underlying tissues around the scar. Motions are slow and the amount of force used is usually light.
