What is the purpose of using electrodes in electrical stimulation?

The purpose of using electrodes in electrical stimulation is to deliver electrical currents to the targeted tissue. Electrodes function as conductors that facilitate the flow of electrical current from the stimulation device to the physiological tissue needing stimulation. This interaction between the electrodes and the tissue allows for effective treatment in various medical and therapeutic applications, such as muscle stimulation, pain relief, and tissue repair.

When electrodes are properly placed on the skin or near the tissue of interest, they help ensure that the current reaches its destination with minimal resistance. This targeted delivery is crucial for the effectiveness of electrical stimulation therapies. While enhancing electrical conductivity could be seen as a secondary benefit, the primary role remains focused on the efficient conveyance of the electrical current to induce the intended physiological response.

Measuring voltage levels does not represent a primary function of electrodes in stimulation contexts, nor does increasing resistance contribute to the desired therapeutic outcomes, as reduced resistance would generally enhance current flow instead.
