A transcutaneous electrical-stimulation system includes a transcutaneous control module including a processor. The transcutaneous control module provides electrical-stimulation signals to electrode sets electrically-coupled to the transcutaneous control module. A first electrode set is electrically-coupled to the transcutaneous control module and is placed along patient skin over a first stimulation location. The first electrode set generates a first effective electric field suitable for transcutaneous stimulation of patient tissue at the first stimulation location. A second electrode set is electrically-coupled to the transcutaneous control module and is placed along patient skin over a second stimulation location. The second electrode set generates a second effective electric field suitable for stimulating patient tissue at the second stimulation location. The second effective electric field is time-delayed from the first effective electric field such that the second effective electric field is out of phase with the first effective electric field.
