Massage balls and rollers are used to help achieve muscle and tension release for all parts of the body. Using these massage balls affects the fascia, a thin sheath layer of connective tissue, that covers all the organs and muscles. Pain in the muscles occurs when the fascia is tightened, forcing the body tissues out of alignment and increasing the pressure on joints and muscles. The main aim of the myofascial therapy is to loosen and stretch the fascia, so that the tissues underneath can have the freedom to move. Massage balls decreases soreness in the muscles and improves range of motion.
