The SENSUS Pain Management System is an electrotherapy device designed for relief of chronic pain in the lower legs and feet. It is worn on the leg, just below the knee and is activated by simply pressing a button. SENSUS is a pain relief option that is both easy and convenient to use. Whenever you need pain relief, activate the device and it will comfortably stimulate the sensory nerves in your legs. Each session lasts 60 minutes with pain relief starting in about 10 to 15 minutes, and often lasting 30 minutes following the end of the session. You may use SENSUS as often as you need.
