20 cases of chronic lymphedema of theleg were examined by lymphoscintigraphybefore and after Heating and Bandage Treat-ment. The result showed that lymph flowwere improved in 17 cases, edematous legsafter the treatment, among these, lymphflow were much improved in 4 patients, al-most reaching a normal state. The compari-son of clarity and appearing time of imagesand the comparison of lymph flow rate be-fore and after the treatment also showed sta-tistical significance.
