ReviewAdvances in the Treatment of Neuropathic Pain by Sympathetic Regulation.
To explore the mechanism and therapeutic effect of sympathetic nerve regulation on neuropathic pain. ⋯ A comprehensive search was conducted in the PubMed and CNKI libraries, using the following keywords: stele ganglion block, neuropathic pain, sympathetic nerve block, sympathetic chemical destruction, and sympathetic radiofrequency thermocoagulation. We selected and critically reviewed research articles published in English that were related to sympathetic modulation in the treatment of neuropathic pain. The collected literature will be classified according to content and reviewed in combination with experimental results and clinical cases. Neuropathic pain was effectively treated with sympathetic regulation technology. Its mechanism includes the inhibition of sympathetic nerve activity, regulation of the inflammatory response, and inhibition of pain transmission, which greatly alleviates neuropathic pain in patients. Stellate ganglion blocks, thoracic and lumbar sympathectomies, chemical destruction, and radiofrequency thermocoagulation have been widely used to treat neuropathic pain. Sympathetic regulation can effectively relieve pain symptoms and improve the patient's quality of life by inhibiting sympathetic nerve activity, reducing the production and release of pain-related mediators, and inhibiting pain transmission. CT-guided radiofrequency thermocoagulation of the thoracic and lumbar sympathetic nerves is effective and durable, with few complications, and is recommended as a treatment for intractable neuropathic pain.

Low back pain is a highly prevalent condition with substantial costs. Superior cluneal neuralgia is present in up to 14% of low back pain cases. This etiology of back pain is often overlooked because the symptoms of superior cluneal neuralgia manifest similarly to those of other conditions, such as radiculopathy and sacroiliac joint pain. Peripheral nerve stimulation (PNS) is an emerging pain management modality used to treat various chronic pain conditions. This retrospective study will examine the outcomes of patients who have back pain caused by neuralgia and are treated with the permanent Freedom® PNS System (Curonix LLC) at the superior cluneal nerve. ⋯ When used to target the superior cluneal nerve, the Curonix Freedom® PNS System is an effective and safe treatment for neuralgia-caused chronic lower back pain resistant to conservative therapy.

Review Meta Analysis
Are combined conservative interventions effective in reducing pain, disability and/or global rating of pain in people with sciatica with known neuropathic pain mechanisms?
National Clinical Guidelines recommend an integrated combination of conservative management strategies for sciatica. However, the efficacy of such combinations have not been established. The purpose of this systemic review with meta-analysis was to determine the efficacy of combined conservative (non-pharmacological) compared to single interventions for people with sciatica with a confirmed neuropathic mechanism. ⋯ There are few studies that have combined conservative (non-pharmacological) interventions for the management of sciatica with a neuropathic component pain mechanism, as recommended by National Clinical Guidelines. This review indicates that combining conservative (no-pharmacological) management strategies appeared more effective than single interventions for the outcomes of low back pain in the short and long term, and for disability in the short term, but not for leg pain at any time point. The overall low certainty of evidence, suggests that future studies with more robust methodologies are needed.

Randomized Controlled Trial Multicenter Study
Improvements in Therapy Experience with Evoked Compound Action Potential Controlled, Closed-Loop Spinal Cord Stimulation - Primary Outcome of the ECHO-MAC Randomized Clinical Trial.
Spinal cord stimulation (SCS) is a well-established treatment for chronic neuropathic pain. However, over- or underdelivery of the SCS may occur because the spacing between the stimulating electrodes and the spinal cord is not fixed; spacing changes with motion and postural shifts may result in variable delivery of the SCS dose and, in turn, a suboptimal therapy experience for the patient. The evoked compound action potential (ECAP)-a measure of neural activation-may be used as a control signal to adapt SCS parameters in real time to compensate for this variability. ⋯ PERSPECTIVE: Patients with chronic pain need durable and dependable options for pain relief. SCS is an important therapy option, and new technology advancements could improve long-term therapy use. CL SCS offers a preferred and more consistent therapy experience for patients that could lead to increased therapy utilization and reliable therapy outcomes.

Dorsal root ganglion stimulation (DRG-S) has emerged as a novel therapeutic approach for managing chronic neuropathic pain. ⋯ This study emphasizes the potential of 4 Hz DRG-S as a valuable alternative to the standard 20 Hz stimulation. Although the exact mechanisms require further investigation, the observed clinical benefits and patient preferences for low-frequency stimulation suggest its viability across diverse pain indications and locations. Additional research is necessary to substantiate these findings and assess the durability and economic implications of low-frequency DRG-S.
