OBJECTIVE: Widespread pain hypersensitivity and enhanced temporal summation of pain (TSP) are commonly reported in patients with complex regional pain syndrome (CRPS) and discussed as proxies for central sensitization. This study aimed to directly relate such signs of neuronal hyperexcitability to the pain phenotype of CRPS patients. METHODS: Twenty-one CRPS patients and 20 healthy controls (HC) were recruited. The pain phenotype including spatial pain extent (assessed in % body surface) and intensity were assessed and related to widespread pain hypersensitivity, TSP, and psychological factors...

OBJECTIVE: Movement-evoked pain (MeP) may predispose the geriatric chronic low back pain (LBP) population to health decline. Since there are differing operational definitions for MeP, the question remains as to whether these different definitions have similar associations with health outcomes in older adults with chronic LBP. DESIGN: Cross-sectional analysis of an observational study. SETTING: Clinical research laboratory. SUBJECTS: 226 older adults with chronic LBP...

OBJECTIVE: Prolonged opioid use is common following traumatic injuries. Although preventive strategies have been recommended, the evidence supporting their use is low. The objectives of this study were to select interdisciplinary strategies to prevent long-term, detrimental opioid use in trauma patients for further evaluation and to identify implementation considerations. DESIGN: A consensus study using the nominal group technique. SETTING: Four trauma systems in Canada...

OBJECTIVES: To evaluate whether combining fast acquisitions with deep-learning reconstruction can provide diagnostically useful images and quantitative assessment comparable to standard-of-care acquisitions for lumbar spine MRI. METHODS: Eighteen patients were imaged with both standard protocol and fast protocol using reduced signal averages, each protocol including sagittal fat-suppressed T2-weighted, sagittal T1-weighted, and axial T2-weighted 2D fast spin-echo sequences...

OBJECTIVES: To assess whether implementation of the Strengthen Opioid Misuse Prevention (STOP) Act was associated with an increase in the percent of opioid prescriptions written for 7 days or less among patients with acute or post-surgical musculoskeletal conditions. DESIGN: An interrupted time series study was conducted to determine the change in duration of opioid prescriptions associated with the STOP Act. SETTING: Data were extracted from the electronic health record of a large healthcare system in North Carolina...

BACKGROUND: It is known that various chronic pain conditions lead to maladaptive changes in the central nervous system. Endometriosis is frequently associated with chronic pelvic pain (CPP). Its sufficient treatment remains a clinical challenge. Transcranial direct current stimulation (tDCS) has been shown to be a powerful method to reduce chronic pain. Therefore, this study aimed to investigate pain reduction via anodal tDCS in patients with endometriosis and CPP. METHODS: This clinical phase-II, placebo-controlled, randomized, parallel designed study included 36 patients with endometriosis and CPP...

OBJECTIVES: Genicular nerve radiofrequency (RF) procedure is increasingly being performed to treat chronic pain due to knee osteoarthritis (OA). Targeting additional sensory nerves and improving target identification by using ultrasound (US) guidance may improve treatment success. The aim of this study was to compare the effectiveness of traditional genicular nerves versus two additional sensory nerves to traditional genicular nerves for US-guided genicular nerve RF procedures in patients with chronic knee OA...

OBJECTIVES: To describe the technique, safety profile, and outcome of CT-guided atlanto-axial lateral articulation injections performed at our institution. METHODS: Consecutive cases of all CT-guided atlanto-axial injections performed from January 2017 to April 2022 at our institution were searched in the electronic medical records. Patient charts were reviewed for demographics, characterization of pain, potential altered anatomy, pain level before and immediately following the procedure, procedure technique, complications, and follow-up outcomes, if available...

OBJECTIVE: Pain evaluation scales often rely on the sense of sight. There is so far no pain assessment scale specifically designed for persons with visual impairment. DESIGN: This study aims to validate a tactile pain evaluation scale, Visiodol©, in blind/visually impaired persons, by correlation with a numeric pain scale (NPS). SETTING: The study took place in University Hospital Clermont-Fd, France. METHODS: Pain intensity for a range of thermal stimuli (Pathway Medoc®) was evaluated with Visiodol© and NPS; secondary outcomes including pain thresholds, catastrophizing, emotion and quality of life were compared in blind/visually impaired and sighted persons...

OBJECTIVE: Evaluate outcomes of genicular nerve chemical neurolysis (GChN) in a real-world population with chronic knee pain. DESIGN: Restrospective, observational cohort study. SETTING: Tertiary academic medical center. SUBJECTS: Consecutive patients who underwent GChN ≥three months prior. METHODS: Standardized surveys were collected by telephone that included the Numerical Rating Scale (NRS), opioid analgesic use, and Patient Global Impression of Change (PGIC)...

OBJECTIVES: Prayer is a devotional practice used across religious traditions to commune with the sacred and has been used as a coping strategy for pain. Previous research on prayer as a pain-coping strategy has mixed results with prayer associated with both greater and lesser pain depending on prayer type. To date there is only one measure of pain-related prayer, the prayer subscale of the Coping Strategies Questionnaire-Revised which solely measures passive prayer, neglecting other types of prayer (e...
