Electrical stimulation has long been used in the treatment of a variety of ailments. Its current uses range from muscle re-education and orthotic substitute to scoliosis management and edema control. I chose to study the effect of electrode polarity in high voltage electrogalvanic stimulation in the treatment of edema for several reasons. I had access to subjects because I was the only physical therapist at the Stockton Orthopedic Medical Group. High voltage electrogalvanic stimulation is a commonly used modality in treating edema (Brown, 1981). High voltage generators have a polarity switch, and the direction manual which accompanies the Electro-Med generator used by the Stockton Orthopedic Medical Group states that the negative pole should be used for edema reduction. (Instruction manual for high voltage Electrogalvanic Stimulator, 1977). However, the effect of electrode polarity on edema reduction has not been demonstrated, nor documented in the literature.
