Myofascial trigger points (MTrPs) are the primary etiological characteristics of chronic myofascial pain syndrome. Receptor tyrosine kinases (RTKs) are associated with signal transduction in the central mechanisms of chronic pain, but the role of RTKs in the peripheral mechanisms of MTrPs remains unclear. The current study aimed to identify RTKs expression in MTrPs and elucidate the molecular mechanisms through which platelet-derived growth factor receptor-α (PDGFR-α) induces contraction knots and inflammatory pain-like behavior in a rat model of myofascial trigger points. ⋯ COL1A1-induced phosphorylation of PDGFR-α and the subsequent activation of the JAK2/STAT3 pathway may induce dysfunctional muscle contraction and increased nociception at MTrPs.

Review Meta Analysis
Effectiveness of pain medication tapering in chronic pain patients: a systematic review and meta-analysis.
This systematic review and meta-analysis aimed to inventory all outcome measures that are affected by tapering in chronic noncancer pain and to investigate the effectiveness of tapering. ⋯ CRD42023416343 (PROSPERO).

Randomized Controlled Trial Multicenter Study
European randomized controlled trial evaluating differential target multiplexed spinal cord stimulation and conventional medical management in subjects with persistent back pain ineligible for spine surgery: 24-month results.
Differential target multiplexed spinal cord stimulation (DTM SCS) was shown to be superior to conventional SCS for treating chronic low back pain (CLBP) in subjects with persistent spinal pain syndrome with previous spinal surgery (PSPS-T2) or ineligible for it (PSPS-T1). This study reports 24-month efficacy and safety of DTM SCS vs. conventional medical management (CMM) in PSPS-T1 subjects across four European countries. ⋯ This randomized controlled trial shows that Differential Target Multiplexed SCS (DTM SCS) is an effective and safe long-term treatment for PSPS type 1 patients suffering from axial low back pain with or without leg pain and who are ineligible for spinal surgery. Currently, CMM treatments are their only option and provide limited benefits. Besides superior pain relief, DTM SCS provides significant improvements in functional disability, quality of life, high levels of satisfaction and perceived impression of change.

Randomized Controlled Trial
Short- and medium-term effects of a single session of pain neuroscience education on pain and psychological factors in patients with chronic low back pain. A single-blind randomized clinical trial.
Biopsychosocial approach in patients suffering chronic low back pain (CLBP) promotes pain self-management strategies. Current evidence recommends high dose of Pain Neuroscience Education (PNE) for clinically significant differences. However, the workload and time constraints experienced by healthcare providers impede the application of the recommended treatment regimen. In fact, Back School with a biomechanical model is the main approach to manage CLBP in public systems. ⋯ Adding a single PNE session in the back school program did not reduce pain but improved psychological factors as central sensitization and pain catastrophism at medium-term.

Pain is a debilitating symptom generally caused by injuries or various conditions. It can be acute, subacute, or chronic and can have a significant impact on a patient's quality of life. The goal of managing pain is to relieve or reduce suffering and improve patient functioning. ⋯ This paper aims to present a review of current performance measures for pain to inform physicians, payers, and policymakers in their selection and use of performance measures. The PMC reviewed 6 performance measures for pain relevant to internal medicine physicians, of which 3 were considered valid at their intended levels of attribution ("Use of Imaging for Low Back Pain," "Use of Opioids at High Dosage in Persons Without Cancer," and "Use of Opioids From Multiple Providers in Persons Without Cancer"). This paper also proposes a performance measure concept to address a quality-of-care gap based on the current clinical guideline from ACP and the American Academy of Family Physicians, "Nonpharmacologic and Pharmacologic Management of Acute Pain From Non-low Back, Musculoskeletal Injuries in Adults."
