TLDR
Clinicians can use the proposed classification algorithm for differentiating neuropathic, nociceptive, and central sensitization pain for each individual patient with chronic pain.
Abstract
Background: The awareness is growing that central sensitization is of prime importance for the assessment and management of chronic pain, but its classification is challenging clinically since no gold standard method of assessment exists. Objectives: Designing the first set of classification criteria for the classification of central sensitization pain. Methods: A body of evidence from original research papers was used by 18 pain experts from 7 different countries to design the first classification criteria for central sensitization pain. Results: It is proposed that the classification of central sensitization pain entails 2 major steps: the exclusion of neuropathic pain and the differential classification of nociceptive versus central sensitization pain. For the former, the International Association for the Study of Pain diagnostic criteria are available for diagnosing or excluding neuropathic pain. For the latter, clinicians are advised to screen their patients for 3 major classification criteria, and use them to complete the classification algorithm for each individual patient with chronic pain. The first and obligatory criterion entails disproportionate pain, implying that the severity of pain and related reported or perceived disability are disproportionate to the nature and extent of injury or pathology (i.e., tissue damage or structural impairments). The 2 remaining criteria are 1) the presence of diffuse pain distribution, allodynia, and hyperalgesia; and 2) hypersensitivity of senses unrelated to the musculoskeletal system (defined as a score of at least 40 on the Central Sensitization Inventory). Limitations: Although based on direct and indirect research findings, the classification algorithm requires experimental testing in future studies. Conclusion: Clinicians can use the proposed classification algorithm for differentiating neuropathic, nociceptive, and central sensitization pain. Key words: Chronic pain, diagnosis, hypersensitivity, classification, neuropathic pain

Assessment and manifestation of central sensitisation across different chronic pain conditions.

TL;DR: Some common fundamental central pain mechanisms are introduced and how they may translate into the clinical signs and symptoms across different chronic pain conditions, how to evaluate gain and loss of function using quantitative pain assessment tools, and the implications for optimising prevention and management of pain are discussed.

Establishing Clinically Relevant Severity Levels for the Central Sensitization Inventory

TL;DR: The aim of this study was to create and validate severity levels for the central sensitization inventory (CSI), a valid and reliable patient‐reported outcome instrument designed to identify patients whose presenting symptoms may be related to a central sensitivity syndrome.

Brain-derived neurotrophic factor as a driving force behind neuroplasticity in neuropathic and central sensitization pain: a new therapeutic target?

TL;DR: This section focuses on combining pharmacotherapy with multimodal rehabilitation for balancing the deleterious and therapeutic effects of BNDF treatment in chronic pain patients, as well as accounting for the complex and biopsychosocial nature of chronic pain.

TL;DR: Diagnostic criteria to establish the presence of central sensitization in patients will greatly assist the phenotyping of patients for choosing treatments that produce analgesia by normalizing hyperexcitable central neural activity.

Neuropathic pain Redefinition and a grading system for clinical and research purposes

TL;DR: A grading system of definite, probable, and possible neuropathic pain is proposed, which includes the grade possible, which can only be regarded as a working hypothesis, and the grades probable and definite, which require confirmatory evidence from a neurologic examination.

TL;DR: A better understanding of neuropathic pain and of the translation of pathophysiological mechanisms into sensory signs will lead to a more effective and specific mechanism-based treatment approach.
