The aim of this economic analysis was to evaluate the cost-effectiveness of differential target multiplexed spinal cord stimulation (DTM-SCS) for treating chronic intractable low back pain, compared with conventional spinal cord stimulation (C-SCS) and conservative medical management (CMM), by updating and expanding the inputs for a previously published cross-industry model. ⋯ Among patients with low back pain treated over a 15-year follow-up period, DTM-SCS and C-SCS are cost-effective compared with CMM, from both payer and societal perspectives. DTM-SCS is associated with a lower ICER than that of C-SCS. Wider uptake of DTM-SCS in the UK health care system is warranted to manage chronic low back pain.

Managing abdominal pain can be difficult. This is due to the nonspecific nature of the pain, the multiple etiologies, and the different mechanisms underlying this type of pain. Abdominal wall pain in particular poses its own challenges. Traditionally, chronic abdominal wall pain has been managed with nonopioid analgesics, and in severe cases, opioid therapy has been considered. For patients with chronic abdominal wall pain refractory to medication management, peripheral nerve blocks and spinal cord stimulation also have been trialed with some success. In this study, we present a case series in patients with chronic abdominal wall pain who were treated with a multicontact peripheral nerve stimulation (PNS) system in the transversus abdominis plane (TAP). ⋯ In patients with chronic abdominal wall pain whose symptoms are refractory to conservative medical management, PNS may be an alternative treatment option. As the use of PNS for chronic abdominal wall pain and other fascial planes continues to develop, additional research is necessary to determine optimal placements and specific stimulation parameters.

In this study, we aimed to investigate the regulatory mechanism of transcranial ultrasound stimulation (TUS) on nitroglycerin-induced migraine in mice. ⋯ Ultrasound stimulation can regulate brain rhythm and blood oxygen metabolism and reduce migraine symptoms in mice. The regulatory mechanism may be related to reducing calcitonin gene-related peptide in blood vessels.

Randomized Controlled Trial
Five-Year Longitudinal Follow-up of Restorative Neurostimulation Shows Durability of Effectiveness in Patients With Refractory Chronic Low Back Pain Associated With Multifidus Muscle Dysfunction.
Adults with refractory, mechanical chronic low back pain associated with impaired neuromuscular control of the lumbar multifidus muscle have few treatment options that provide long-term clinical benefit. This study hypothesized that restorative neurostimulation, a rehabilitative treatment that activates the lumbar multifidus muscles to overcome underlying dysfunction, is safe and provides relevant and durable clinical benefit to patients with this specific etiology. ⋯ The Clinicaltrials.gov registration number for the study is NCT02577354; registration date: October 15, 2016; principal investigator: Christopher Gilligan, MD, Brigham and Women's Hospital, Boston, MA, USA. The study was conducted in Australia (Broadmeadow, New South Wales; Noosa Heads, Queensland; Welland, South Australia; Clayton, Victoria), Belgium (Sint-Niklaas; Wilrijk), The Netherlands (Rotterdam), UK (Leeds, London, Middlesbrough), and USA (La Jolla, CA; Santa Monica, CA; Aurora, CO; Carmel, IN; Indianapolis, IN; Kansas City, KS; Boston, MA; Royal Oak, MI; Durham, NC; Winston-Salem, NC; Cleveland, OH; Providence, RI; Spartanburg, SC; Spokane, WA; Charleston, WV).
