Movement should be restricted in musculoskeletal injuries, which allows the body to use its nutrients and oxygen to promote healing. Also, fibrin and collagen can more easily form across wound edges when there is little movement or disruption to the area.
Cold application promotes vasoconstriction and decreases swelling, pain, and congestion in the inflammed or injured area.
Direct pressure reduces vasodilating effects and the development of edema, along with compression bandages that provide support to injured joints, tendons, and muscles.
When an extremity is elevated above the level of the heart, edema is reduced at the injury site by increasing venous and lymphatic return.
