REFERS TO A RELATIVELY LARGE ELECTRODE DELIVERYING THE POSITIVE CURRENT FROM A STIMULATOR INTO THE BODY. IT IS NORMALLY APPLIED TO THE LARGER, THICKER AREA OF MUSCLE SO THAT THE CURRENT CAN"DISPERSE" THROUGH THE TREATED AREA. THE CURRENT THEN LEAVES THE BODY THROUGH THE USUALLY SMALLER, CONVENTIONAL NEGATIVE ELECTRODE. THE PHOTO ON THE EMS2A FLYER GIVES A GOOD REPRESENTATION OF THIS IN ACTION. THE DISPERSIVE ELECTRODE IS THE ONE UNDER THE FOREARM IN THE PICTURE.
