Objectives: The goal of this study was to identify central sensitization-related symptom severity subgroups in a large multicountry sample composed of patients with chronic pain and pain-free individuals using the Central Sensitization Inventory (CSI).

Methods: A large, pooled international (N = 8 countries) sample of chronic pain patients plus healthy subjects (total N = 2,620) was randomly divided into two subsamples for cross-validation purposes. First, a hierarchical cluster analysis (HCA) was performed using CSI item-level data as clustering variables (test sample; N = 1,312).

Objective: Chronic musculoskeletal pain disorders (CMPDs) are among the leading causes of disabilities across populations, resulting in high social and financial burden. This persistent pain condition may include the central sensitization (CS) phenomenon, which implies a wide range of symptoms and that may be taken into account in CMPD treatment. CS symptoms can be measured by the Central Sensitization Inventory (CSI).

Background: Pain-related fear-avoidance (FA) is a common problem affecting many patients with painful medical conditions. As there is great interest in the clinical importance of the relationship between FA and disability, several questionnaires have been developed to measure FA. The Fear-Avoidance Components Scale (FACS) is a recently developed patient-reported instrument that addresses critical issues not previously considered in previous FA-related questionnaires.

Background: Identifying how pain transitions from acute to chronic is critical in designing effective prevention and management techniques for patients' well-being, physically, psychosocially, and financially. There is an increasingly pressing need for a quantitative and predictive method to evaluate how low back pain trajectories are classified and, subsequently, how we can more effectively intervene during these progression stages.

Methods: In order to better understand pain mechanisms, we investigated, using computational modeling, how best to describe pain trajectories by developing a platform by which we studied the transition of acute chronic pain.

This article reviews the complexities of the opioid epidemic, considering recent research involving the current state of the opioid epidemic; chronic pain and its role in the crisis; the properties of opioids and how they interact with human neurobiology; the effectiveness and risks of opioids as a treatment for chronic pain; opioid addiction and dependence; and pharmacological and psychological interventions for opioid addiction, opioid dependence, and chronic pain management. Opioid abuse can be reduced with the availability and access to treatment facilities for opioid detoxification; using interdisciplinary treatment models for chronic pain, opioid addiction and dependence; conducting more research in the areas of opioid addiction and opioid dependence; and shifting to an increase in nonpharmacological, less invasive treatments for pain.

Article Synopsis
  • A study of 202 patients with chronic low back pain found that over 25% didn't use non-drug treatments, with older patients more likely to use opioids.
  • Patients on opioids experienced worse pain and disability compared to those on NSAIDs, while those using both reported the worst outcomes in quality of life.
  • After considering other factors, the study concluded that neither opioids nor their combination with NSAIDs was more effective than NSAIDs alone, highlighting the need for better non-drug and alternative therapies.

Article Synopsis
  • The traditional view of pain progression suggests a simple linear path from acute to chronic pain, but recent findings indicate that this process is much more complex and varies from person to person.
  • It is crucial to explore and classify different pain trajectories, particularly for low-back pain, to ensure more effective intervention and treatment strategies.
  • This article emphasizes the need for an improved model of patient evaluation to better understand and address individual pain experiences and needs.

Unlabelled: After the 2011 Institute of Medicine report on chronic pain, the Interagency Pain Research Coordinating Committee (IPRCC) was created to enhance research efforts among federal agencies. The IPRCC and Office of Pain Policy at the National Institutes of Health collaborated to identify gaps in knowledge and address them via a Federal Pain Research Strategy (FPRS). Interdisciplinary work groups (WGs) were established to make research recommendations in 5 areas: prevention of acute and chronic pain, acute pain and acute pain management, transition from acute to chronic pain, chronic pain and chronic pain management, and disparities in pain and pain care; cross-cutting issues were also considered.

Unlabelled: Central sensitization (CS) involves the amplification of neural signaling within the central nervous system, which evokes pain hypersensitivity. The Central Sensitization Inventory (CSI) assesses 25 overlapping health-related symptom dimensions that have been reported to be associated with CS-related disorders. Previous studies have reported satisfactory test-retest reliability and internal consistency, but factor analyses have exhibited conflicting results in different language versions.

A recent literature review concluded that the comorbidity of chronic pain and depression in adults is approximately 50%-65%. Physical and cognitive declines, concurrent multiple health conditions, and complex medication regimens add to the unique and complex challenges of effectively treating pain in particularly geriatric populations. Interdisciplinary medical intervention and monitoring for psychiatric sequelae, such as depression, cognitive change, and synergistic physical side effects are necessary.

Article Synopsis
  • Functional restoration programs (FRPs) effectively reduce psychosocial distress and improve work return rates for patients with chronic disabling occupational musculoskeletal disorders (CDOMDs), with evidence suggesting shorter lengths of disability (LOD) lead to better outcomes.
  • This study assessed the impact of extended LOD (over 18 months) on treatment outcomes in a cohort of 1,413 CDOMD patients, categorizing them into different groups based on their LOD.
  • Results indicated that longer LOD correlated with a lower likelihood of completing the FRP and worse initial patient-reported outcomes (pain, disability, depression), although improvements were observed across all groups by treatment discharge.

Functional near-infrared spectroscopy (fNIRS) was used to examine hemodynamic responses in the prefrontal cortex (PFC) during noxious thermal pain, induced by thermal stimulations over three different body sites over the right forearm, right temporomandibular joint, and left forearm. Functional NIRS measurements were obtained from three groups of healthy volunteers, one group for each body region. Each group was subjected to both low-pain stimulation (LPS) and high-pain stimulation (HPS) by a [Formula: see text] thermode of a temperature-controlled thermal stimulator over the respective three body sites.
