Padding plays a key role in complete decongestive therapy. Padding is placed on top of the stockinette, under the compression bandages. The goal of the various padding applications depends on the type of padding used. In cases of hardened tissue areas (fibrosis), treatment may require the use of higher density, or specialty foam (foam pads, channeled foam, swell spots) to help break up the fibrotic tissue and return the skin to its normal softness. Foam pads come in many different shapes and sizes.
