Spinal cord stimulation is the main neuromodulation therapy for certain chronic neuropathic pain conditions. This article describes neuromodulation and the process of spinal cord stimulation therapy. It also clarifies the suitability of a patient for referral and consideration for spinal cord stimulation.

Case ReportsDorsal Root Ganglion Stimulation for Treatment of Chemotherapy-Induced Neuropathy: A Case Report.
Chemotherapy-induced neuropathy has limited treatment options, and conventional medications used to treat neuropathic pain often do not provide adequate pain relief for patients with a history of cancer. Neuromodulation such as dorsal root ganglion stimulation remains a treatment that has been studied for chronic painful conditions such as low back pain, pelvic pain, complex regional pain syndrome, and phantom limb pain. Dorsal root ganglion stimulation has been presented for treatment of chemotherapy-induced neuropathy, but with limited duration of follow-up. ⋯ After failure of conservative pharmacotherapies, a 7-day dorsal root ganglion stimulation trial was implanted, resulting in 100% pain relief. A dorsal root ganglion stimulation was then implanted permanently, and our patient reported continued resolution of symptoms at evaluation 3 yrs after placement. To the author's knowledge, this is the first case of sustained relief with dorsal root ganglion stimulation placement for chemotherapy-induced neuropathy and presents a treatment option that warrants further investigation.

Review Meta AnalysisPrevalence of chronic pain after spinal cord injury: a systematic review and meta-analysis.
The reported prevalence of chronic pain after spinal cord injury (SCI) varies widely due, in part, to differences in the taxonomy of chronic pain. A widely used classification system is available to describe subcategories of chronic pain in SCI, but the prevalence of chronic pain in SCI based on this system is unknown. ⋯ This systematic review and meta-analysis extends the findings of previous studies by reporting the prevalence of chronic pain after SCI based on the ISCIP classification system, thereby reducing clinical heterogeneity in the reporting of pain prevalence related to SCI.

Peripheral nerve stimulation (PNS) is a rapidly expanding field within neuromodulation; however, there is limited data on therapeutic efficacy. This study describes the indications and clinical outcomes for patients undergoing PNS for chronic pain states. ⋯ Peripheral nerve stimulation was associated with reduced pain scores, lower opioid utilization, and improved patient function at 6 months. These data support PNS as a potentially effective nonopioid analgesic modality in chronic pain, though prospective multicenter evaluation is warranted to evaluate longer-term outcomes.

A new wireless spinal cord stimulation (SCS) technology, which was introduced in recent years, promises minimal invasive SCS as well as additional advantages such as a wide range of stimulation paradigms and 3-T magnetic resonance imaging (MRI) conditionality. ⋯ Minimal invasive implantation of wireless SCS systems was feasible and safe. The device offered a broader range of stimulation paradigms compared to conventional SCS devices, an allowed for a prolonged testing phase and continuous adjustment of SCS programs.
