System and method for simultaneously modulating ascending and descending neural pain pathways using spinal cord stimulation

Abstract

The invention relates to a system and method for improving spinal cord stimulation (SCS) by simultaneously modulating ascending and descending pain pathways. The invention utilizes a Randomized Intermittent Dichotomous Stimulation (RIDS) paradigm, introducing a randomly timed target stimulation signal interspersed with a background stimulation signal. This novel method enhances the cognitive processing of pain signals by utilizing event-related potentials, such as the P300 brain potential, to activate both inhibitory pathways and minimize pain habituation. The target stimulus, distinct from the background SCS signal, elicits a cognitive response by prompting the patient to recognize the target and perform a physical or mental task. This simultaneous modulation of pain pathways increases treatment efficacy, extends the longevity of SCS therapy, and reduces habituation effects, offering an optimized therapeutic solution for chronic pain management.
