Spinal Cord Stimulation What Do We Know?

Abstract

Neurochemical effects:There is no relation between SCS and opioid release, there is an increase dorsal horn GABA expression seen in animal model after SCS stimulation, levels of Substance P and serotonin are shown to be elevated by SCS. Studies have proven that excitatory amino acid release is suppressed by SCS via action on GABA-B receptors and intra-thecal adenosine as well baclofen may potentiate the effect of SCS. The net effect of these neurochemical effects reduces dorsal horn neuronal excitability [3].
