This invention provides a mechanical lower extremity manipulation device to increase venous blood flow in lower extremities for the prevention of deep vein thrombosis (DVT), pulmonary embolism (PE), lower extremity edema, and other associated or related conditions. Foot plates pivoting on a base plate can be powered to provide a reciprocating action to the feet of a reclining patient. Straps can hold the patient's legs against the base plate so that the reciprocating action results in alternate planar flexion and dorsal flexion of the foot without movement of the leg in general. The resulting elongation and retraction of lower leg muscles can improve venous blood flow to reduce the risk of pathologies, such as DVT.
