ReviewRole of patient selection and trial stimulation for spinal cord stimulation therapy for chronic non-cancer pain: a comprehensive narrative review.
Patient selection for spinal cord stimulation (SCS) therapy is crucial and is traditionally performed with clinical selection followed by a screening trial. The factors influencing patient selection and the importance of trialing have not been systematically evaluated. ⋯ Due to lack of a consistent approach to identify responders for SCS therapy, trialing complements patient selection to exclude patients who do not find the therapy helpful and/or intolerant of the SCS system. However, more rigorous and large studies are necessary to better evaluate its role.

Role of peripheral nerve stimulation in treating chronic neuropathic pain: an international focused survey of pain medicine experts.
Interventional pain management (IPM) options for refractory neuropathic pain (NP) have recently increased with availability of peripheral nerve stimulation (PNS) equipment and expertise. Given a lack of high-quality evidence and guidelines on this topic, we sought to understand the perception of physicians with expertise in treating NP regarding IPM and the role of PNS. We emailed a survey in March 2022 to international NP experts including pain medicine physicians, researchers, and leaders of 11 professional pain societies. ⋯ Twenty-two respondents (92%) agreed PNS should be offered early in the treatment of neuropathic pain. The most common barriers to PNS use were cost, lack of high-quality evidence in support of its use, lack of exposure to PNS in training programs, and lack of familiarity with the use of ultrasound guidance. PNS appears to have an increasing role in the treatment of NP but more research is needed on the outcomes of PNS to elucidate its role.

Trends in spinal cord stimulation utilization: change, growth and implications for the future.
Chronic pain impacts more than 100 million Americans and has a significant impact on the economy and quality of life. Spinal cord stimulation (SCS) has demonstrated efficacy in managing a growing number of chronic pain conditions. This in combination with an increasing number of physicians trained in SCS placement has produced significant changes in utilization, expense and sites of service related to SCS. ⋯ There is a large potential market and use of these therapies is predicted to grow from $2.41 billion in 2020 to $4.12 billion US dollars globally by 2027. At the same time, there is increasing scrutiny around utilization of this therapy related to cost, complications, long-term efficacy and explant rates that has the potential to impact access to this therapy in the future. We must examine our indications, technique and management to optimize outcomes and utilization of SCS going forward.

Review Meta AnalysisPhysical functioning following spinal cord stimulation: a systematic review and meta-analysis.
Spinal cord stimulation (SCS) has emerged as an important treatment for chronic pain disorders. While there is evidence supporting improvement in pain intensity with SCS therapy, efforts to synthesize the evidence on physical functioning are lacking. ⋯ This meta-analysis highlights significant improvements in physical function after SCS therapy. However, this finding was limited by a very low GRADE certainty of evidence and high heterogeneity.
