An electrode system for transcutaneous nerve and/or muscle stimulation that includes a pair of stimulating electrodes and a stimulation current generator for generating a nerve and/or muscle stimulation current between the stimulating electrodes. The system also includes a current-injecting electrode arranged in proximity to one of the stimulating electrodes, and an injection-current generator located in the area of the current-injecting electrode. The current-injecting electrode and the corresponding injection-current generator reduce, or even eliminate, undesirable sensations resulting from an excitation of subcutaneous receptors by the stimulation current.
