Background: Despite a broad clinical use, the mechanism of action of SCS is poorly understood. Current information suggests that the effects of SCS are mediated by a complex set of interactions at several levels of the nervous system including spinal and supraspinal mechanisms. Aims: The study was undertaken to investigate the influence of SCS on distinct parameters of cortical excitability using single- and paired-pulse transcranial magnetic stimulation (TMS). Methods: Five patients with chronic neuropathic pain were examined with the SCS stimulator on and off by means of TMS. Pain was assessed using a visual-analogue scale. Electro physiological and pain parameters of patients during this procedure were compared by means of a linear mixed effect model. Results: SCS induced a significant modulation of cortical excitability, especially by influencing the parameter "intracortical facilitation" (t = -2.657; df = 8; p = 0.029). A significant relationship between this parameter and "perceived pain" could be obtained (t = -4.798; df = 8; p = 0.002). Conclusions: These results suggest that SCS is able to influence neurobiological processes at the supraspinal level and that clinical effects of SCS may be at least in part of cortical origin.
