Regarding the treatment of lymphedema, the International Society of Lymphedema (ISL) views Combined Physical Therapy (CPT) as the most important conservative treatment. For the lymphedema training committee in the “Cancer rehabilitation training” project commissioned by the Ministry of Health, Labour and Welfare in Japan, the conservative treatment of lymphedema is based on a “combined treatment” of daily lifestyle instruction and CPT. CPT includes skincare, manual lymph drainage (MLD), compression therapy, and pressurized therapeutic exercises. In skincare, it is important to clean, moisturize, and protect the skin in order to prevent the infection/inflammation of the diseased limb. In daily life training, instruction is given about precautions in daily life regarding the main causes and aggravating factors of lymphedema. MLD guides the lymph fluid so as to bypass the damaged lymph tube section that has caused the swelling and reach the normal lymph tube system through the lymph capillary through the movement of the lymph in various directions that do not have non-return valves. Compression treatment attempts to improve lymphedema through the application of suf ficient pressure from elastic bandages or elastic clothing. Pressurized therapeutic exercises promote greater drainage of lymph fluid.
