Neurophysiological Effects of Dorsal Root Ganglion Stimulation (DRGS) in Pain Processing at the Cortical Level.
Dorsal root ganglion stimulation (DRGS) has been used successfully against localized neuropathic pain. Nevertheless, the effects of DRGS on pain processing, particularly at the cortical level, remain largely unknown. In this study, we investigated whether positive responses to DRGS treatment would alter patients' laser-evoked potentials (LEP). ⋯ DRGS is able to restore LEPs to normal values in patients with localized neuropathic pain, and LEP alterations are correlated with clinical response in terms of pain intensity.

Neuropathic pain is an entity that causes patient disability and its diagnosis and treatment is a challenge for physicians. In a significant percentage of patients with neuropathic pain, it is restricted to one dermatome or to a particular region of the body; in this case, it is referred to as localized neuropathic pain. There are no Mexican clinical guidelines proposing recommendations for the diagnosis and treatment of localized neuropathic pain in our population. This article presents the recommendations of a multidisciplinary consensus of specialists from different areas involved in the diagnosis and treatment of this type of patients.
