Foams are an integral part of multi-layer compression bandaging and play a key role in complete decongestive therapy, or "CDT", which is performed to reduce limb volume as part of a Lymphedema treatment program. (read more)
Multi-layer compression bandaging includes a second layer of padding which is placed over the initial layer of stockinette. This secondary "padding" layer will likely consist of a simple soft padding made of polyester, cotton, or light weight foam and is used to help cushion limb and bony areas, prevent sharp indentations or skin irritations, and help evenly distribute the gradient pressure created by the compression bandages.
In cases of excess swelling or fibrosis, which is a hardened area under the skin, CDT may require the use of a higher density or specialty foam to help break up the fibrotic tissue and return the skin to its normal softness. Thicker and higher density or specialty channeling foams are generally useful in helping to treat fibrotic areas and provide additional padding. However, in cases of heavy fibrosis and thick skin, a denser closed-cell or rubber foam may be required, as the density of these foams provides additional compression which helps to loosen the fibrotic tissues. Several uniquely designed swell spots and pads have been developed to help treat and manage specific areas of swelling which are particularly problematic or require unique localized pressure.
Which ever type of foam or padding is used, the goal is to create pressure and break up the areas of concentrated and stagnant protein-heavy lymph fluid to help create a softer skin area.
