The Venen Engel EMS Vein Board is a medically certified device that uses electrical impulses to stimulate the muscle-venous-pump in the legs. Electromyostimulation helps to increase blood flow and support venous circulation. The EMS Vein Board is primarily used in the supportive treatment of conditions such as venous insufficiency, oedema and varicose veins. It can also be used to promote lymph flow in the legs to reduce swelling and fluid retention.
