[Dependency syndrome]

Abstract

The most common causes of lower limb edema include cardiac insufficiency, venous insufficiency, insufficiency of lymph flow, and side effects of drugs. It can also be due to dependency syndrome, in which the edema and skin changes can only be explained by a passive calf muscle pump and the resulting venous hypertension. Underlying the drop foot is always immobilization for one reason or other. The patient must be given an explanation about the situation, activated to move if possible, and in any case guided to the use of support stockings and postural therapy.
