OBJECTIVE: Opioids are frequently used in spine surgeries despite their adverse effects, including physical dependence and addiction. Gender difference is an important consideration for personalized treatment. There is no review assessing the prevalence of opioid use between men and women before spine surgeries. DESIGN: We compared the prevalence of preoperative opioid use between men and women. SETTING: Spine surgery. SUBJECTS: Comparison between men and women...

SUMMARY OF BACKGROUND DATA: No study has evaluated the relationship between contrast dispersion patterns and outcomes after fluoroscopically guided cervical transforaminal epidural steroid injection (CTFESI). OBJECTIVES: Determine whether contrast dispersion patterns predict pain and functional outcomes after CTFESI. METHODS: Secondary analysis of data collected during two prospective studies of CTFESI for the treatment of refractory radicular pain...

OBJECTIVE: This systematic review aimed to evaluate the effectiveness of different interventions at reducing pain-related fear in people with fibromyalgia and to analyze whether the included trials reported their interventions in full detail. DESIGN: Systematic review. SETTING: No restrictions. METHODS: The Cochrane Library, CINAHL, EMBASE, PsycINFO, PubMed, and Scopus were searched from their inception to April 2020, along with manual searches and a gray literature search...

BACKGROUND: Exercise is recommended to promote and maintain health and as treatment for more than 25 diseases and pain conditions. Exercise-induced hypoalgesia (EIH), a measure of descending pain inhibitory control, has been found to be impaired in some chronic pain conditions, but it is currently unclear if EIH is modifiable. This study investigated whether a long-term exercise intervention could modulate EIH in healthy subjects. METHODS: In 38 healthy subjects, EIH was assessed as change in pressure pain threshold (PPT) after a three-minute isometric wall squat within the first week and after approximately seven weeks of military training (MT)...

BACKGROUND: Genicular nerve radiofrequency ablation (RFA) for the treatment of chronic knee pain has traditionally targeted the superomedial, superolateral, and inferomedial genicular nerves. However, recent cadaveric studies of knee neuroanatomy demonstrate varied locations of these specific nerves as well as additional articular nerves. This work suggests that traditional genicular nerve RFA lesion locations may be inadequate. OBJECTIVE: 1) To describe a novel protocol utilizing a three-tined RFA electrode to target the superomedial (SMGN), superolateral (SLGN), and inferomedial genicular nerves (IMGN), as well as the terminal articular branches of the nerves to the vastus medialis (NVM), intermedius (NVI), and lateralis (NVL)...

OBJECTIVE: Chronic pain is more common among veterans than among the general population. Expert guidelines recommend multimodal chronic pain care. However, there is substantial variation in the availability and utilization of treatment modalities in the Veterans Health Administration. We explored health care providers' and administrators' perspectives on the barriers to and facilitators of multimodal chronic pain care in the Veterans Health Administration to understand variation in the use of multimodal pain treatment modalities...

OBJECTIVE: To examine stressor elevations among older adults with pain, and gender and race disparities in the dual burdens of late-life pain and stressors. DESIGN: Cross-sectional. SETTING: Community. SUBJECTS: Participants in the Longitudinal Late-Life Health study (LLLH; N = 1,884) and the Health and Retirement Study (HRS; N = 7,704). METHODS: Pain and stressor measures were harmonized across the LLLH and HRS samples...

OBJECTIVES: To explore the features of high-intensity zone (HIZ) in anterior annulus fibrosus and assess the association of anterior HIZ with low back pain (LBP). DESIGN, SETTING, AND SUBJECTS: A retrospective study of 5,940 discs in 1,188 individuals was conducted. METHODS: Subjects' information and LBP symptoms confirmed by an orthopedic surgeon were acquired from the medical record. Magnetic resonance (MR) image reading and analysis were performed by two experienced blinded radiologists...

OBJECTIVE: To estimate all-cause and overdose crude mortality rates and standardized mortality ratios among people prescribed opioids for chronic noncancer pain and risk of overdose death in this population relative to people with similar clinical profiles but not prescribed opioids. DESIGN: Systematic review and meta-analysis. METHODS: Medline, Embase, and PsycINFO were searched in February 2018 and October 2019 for articles published beginning 2009...

OBJECTIVE: Remote electrical neuromodulation (REN) is a nonpharmacological acute migraine treatment that stimulates upper-arm peripheral nerves. The aim of this investigation was to evaluate the effectiveness and safety of REN for acute treatment of migraine in a real-world setting. METHODS: Real-world data were collected from patients who were using REN (Nerivio®, Theranica Bio-Electronics Ltd., Israel) between October 1, 2019, and March 31, 2020. Patients recorded their symptoms at baseline, two hours, and 24 hours post-treatment...

OBJECTIVE: This study describes individual cancer patients' nonuse of extended-release or long-acting (ER/LA) opioids, including periods of gap between opioid doses taken. DESIGN: Secondary analysis of a three-month observational study of prescribed ER/LA opioids monitored using electronic pill caps. SETTING: Two outpatient oncology clinics of a large health system in the Mid-Atlantic region. PARTICIPANTS: Inclusion was based on self-identified African Americans and whites, at least 18 years old, diagnosed with solid tumors or multiple myeloma...

OBJECTIVE: Central sensitization is present in different pain conditions, including chronic whiplash-associated disorders. In the absence of a gold standard method of assessment to determine the presence of central sensitization, quantitative sensory testing is currently understood as an optimal proxy. Laboratory sensory testing is, however, not feasible in clinical practice, and the Central Sensitization Inventory was developed as an alternative. The aim of the current study was to evaluate the convergent validity of the Central Sensitization Inventory in chronic whiplash-associated patients by determining the association between the Central Sensitization Inventory and quantitative sensory testing, pain intensity, fatigue, and psychosocial factors...

OBJECTIVE: To determine the effectiveness of cervical medial branch thermal radiofrequency neurotomy in the treatment of neck pain or cervicogenic headache based on different selection criteria. DESIGN: Comprehensive systematic review. METHODS: A comprehensive literature search was conducted, and the authors screened and evaluated the studies. The Grades of Recommendation, Assessment, Development, and Evaluation system was used to assess all eligible studies...

OBJECTIVE: Kinesiophobia (i.e., fear of movement caused by pain) is increasingly acknowledged as a determinant of disuse among patients with chronic musculoskeletal pain. Kinesiophobia may affect life space-a crucial indicator of an active lifestyle among older people. This study aimed to investigate the previously unexamined association between kinesiophobia and life space among community-dwelling older people with chronic musculoskeletal pain. DESIGN: Cross-sectional study...

BACKGROUND: Previous studies suggest that increased cerebrovascular reactivity might be a feature of patients who have migraine with aura (MwA). The correlation between the clinical presentation of migraine with aura and transcranial Doppler parameters remains unclear. OBJECTIVE: The main aim of this study was to explore cerebral blood flow, vascular resistance, and cerebrovascular reactivity in women MwA. Also, the relationships between hemodynamic conditions and aura characteristics are examined...
