The REVITIVE IX is a medical device designed to increase leg circulation. It uses Electrical Muscle Stimulation (EMS) to stimulate the muscles in your lower legs and feet to help counteract stasis and help maintain healthy legs. By placing your bare feet on each of the footpads, therapeutic electrical impulses stimulate the nerve endings on the soles of your feet. This causes the contraction and relaxation of muscles in the lower legs. This action is clinically tested & shown to increase circulation. Use REVITIVE IX daily and feel the difference in yourself. Blood flows around your body as part of the circulatory system. Our bodies were designed to be active and so when you walk your leg muscles actively contract and relax, to pump the blood up through the legs and back to the heart. Healthy leg circulation is where blood carries carbon dioxide and waste products pumped from your legs through your veins back to the heart and oxygenated blood is returned to the legs. Unfortunately if you are unable to take regular exercise, the leg muscle pumps are less active and blood flow is reduced. This can cause blood and fluid to pool in the legs and may cause swelling and discomfort. After placing both bare feet on the footpads of the REVITIVE IX Circulation Booster™, increase the intensity level for the feet (levels 1-99) until you feel strong, comfortable, non-painful muscle contraction. This feels like a tingling, pins and needles sensation. You can control the intensity and duration with the easy-to-use remote control. Just 20 to 30-minutes per day is recommended to experience the benefits. Unsuitable is you are fitted with a heart pacemaker or ACID, being treated for, or have the symptoms of an existing Deep Vein Thrombosis (DVT), or you are pregnant. Always read the label. Use only as directed. If you are uncertain about the cause of your symptoms or your symptoms persist, please consult your doctor.
