This paper is an overview of the results of computer modeling of spinal cord stimulation, started ten years ago at the University of Twente, The Netherlands. Results are given of the analysis of various geometrical factors, including spinal anatomy, which influence the effect of spinal cord stimulation on nerve fiber recruitment and paresthesia coverage. ⋯ Two new electrode types are presented: the narrow bi-/tripole and the transverse tripole. The latter also enables adjusting the body area affected with paresthesia by means of a dual channel pulse generator giving simultaneous pulses, thereby limiting surgical interventions for electrode repositioning.
