Radical resection of gynecological malignant tumor combined with bilateral pelvic lymph node dissection can bring benefits to patients as well as disadvantages， radical namely，lymphedema，which bring about pain and emotional sequelae，further development can restrict lower limb joints，even cause joint activity limitation and loss of function. Therefore，although lymphedema is not a fatal disease，it can seriously affect the life quality of patients. In the treatment of the lower limb lymphedema，exercise is an essential part，which can accelerate the lymph circulation and promote the regression of edema. Therefore，the purpose of this paper is to review the present situation，formation mechanism，treatment and functional exercise methods，as well as the deficiencies of functional exercise of lower extremity edema after pelvic lymph node dissection for cervical cancer，and to provide a strong theoretical basis for clinical research.
