Abstract
An electrical stimulation system includes an implantable control module having a processor. The control module provides electrical stimulation signals to one or more leads coupled to the control module for stimulation of patient tissue to treat pain. A first electrode is disposed on the one or more leads in the patient'"'"'s spinal cord and communicates with the processor to generate a first effective electric field suitable for stimulating patient tissue using the electrical stimulation signals provided from the control module. A second electrode is disposed on the one or more leads and communicates with the processor to generate a second effective electric field suitable for stimulating patient tissue using the electrical stimulation signals provided from the control module. 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.
