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.

A above knee prosthesis (P) applied to femoral connection (100) of an amputee that comprises a upper hinge (1) connected to femoral connection of the patient, an articulation axis (2) with the function of reproducing the knee movements, a tibia-calf muscle unit (3) pivotally connected to the femoral•segment and a damper (5) that reproduces some functions of the calf muscle and ensures to the prosthesis to brake and to allow the sequential swing and stance phases typical of the gait. The damper comprises a cylinder (5c) wherein a piston (10) and a stem (9) act connected to each other and adapted to carry out a damping reaction of said damper responsive to the forces loaded on the prosthesis. In particular, a force transducer is provided in the damper arranged, in particular, in the stem with a microprocessor that receives a force signal from the transducer and operates means for adjusting the reaction of the damper responsive to the detected force signal.
