Comprilan(R) short stretch bandage measures 4 cm x 5 m and works on the principle of applying a low amount of pressure when the muscle is resting/not active.When the muscle is active, such as the calf muscle when walking, the short stretch bandage applies resistance to the muscle, also known as working pressure. The resistance or working pressure applied by a Comprilan short stretch bandage occurs because of the bandages limited stretch characteristic.
