- Recently, the International Association for the Study of Pain (IASP) released clinical criteria and a grading system for nociplastic pain affecting the musculoskeletal system. These criteria replaced the 2014 clinical criteria for predominant central sensitization (CS) pain and accounted for clinicians' need to identify (early) and correctly classify patients having chronic pain according to the pain phenotype. Still, clinicians and researchers can become confused by the multitude of terms and the variety of clinical criteria available. Therefore, this paper aims at (1) providing an overview of what preceded the IASP criteria for nociplastic pain ('the past'); (2) explaining the new IASP criteria for nociplastic pain in comparison with the 2014 clinical criteria for predominant CS pain ('the present'); and (3) highlighting key areas for future implementation and research work in this area ('the future'). It is explained that the 2021 IASP clinical criteria for nociplastic pain are in line with the 2014 clinical criteria for predominant CS pain but are more robust, comprehensive, better developed and hold more potential. Therefore, the 2021 IASP clinical criteria for nociplastic pain are important steps towards precision pain medicine, yet studies examining the clinimetric and psychometric properties of the criteria are urgently needed.

- The Central Sensitization Inventory (CSI) measurement properties in patients having nonspecific, noncancer pain are well-established. However, studies examining the reliability and validity of either the CSI or the Central Sensitization Inventory short-form version (CSI-9) in breast cancer survivors (BCS) are scarce. The purpose was to evaluate convergent validity and internal consistency of the CSI and CSI-9. Additionally, the relevance of a new cluster calculator using the CSI was explored. The cross-sectional multi-center study included 65 BCS and 37 healthy volunteers. Patients filled out multiple questionnaires assessing pain, number of painful areas, anxiety, depression and quality of life. The relevance of a cluster calculator was explored by known-group comparisons and boxplot description. All hypotheses were formulated before data analysis. The majority of hypotheses on the correlations between the CSI or CSI-9 and other health outcomes were confirmed (22 out of 27). The CSI and CSI-9 have excellent (alpha = 0.92) and good (alpha = 0.86) internal consistency, respectively. The CSI cluster calculator might be an interesting tool to use to have a patient's overall condition snapshot. Generally, the study findings support the construct validity and internal consistency of the CSI, which underline the use of this self-reported instrument in BCS. The CSI-9 shows promising results, but should be further evaluated.

- Background: The presence of pain decreases survival rates in cancer. Pain management in clinical settings is often suboptimal and secondary to other cancer-related treatments, leaving many people undertreated. Opioid use is associated with side effects and decreased survival rate in cancer patients. Hence, there is an urgent need for considering factors such as perceived injustice that sustain post-cancer pain and trigger a behavioral pattern associated with opioid use. Injustice beliefs represent a maladaptive pattern of cognitive appraisal that may be a salient target for improving pain-related coping in these patients. Perceived injustice is associated with increased opioid prescription and prospectively predicted opioid use at 1-year follow-up, urging the need for targeted interventions to diminish perceived injustice. Objectives: Explain the importance of screening for perceived injustice in patients with pain following cancer treatment, its potential relevance for opioid abuse, and its potential impact on the management of pain following cancer. Also, prove clinicians with a clinical guide for an approach comprising of modified pain neuroscience education, motivational interviewing, and acceptance-based interventions to account for perceived injustice in patients having pain following cancer. Study Design: A narrative review, perspective and treatment manual Setting: Several universities, a university of applied science department, a university hospital, and a private clinic (i.e., transdisciplinary pain treatment center). Methods: Patients were cancer survivors with pain. Intervention included modified pain neuroscience education, motivational interviewing, and acceptance-based interventions. Measurements were taken through the Injustice Experience Questionnaire (IEQ). Results: The IEQ can be used to assess perceived injustice in a valid way. Education about pain, including discussing perceived injustice, should be the first part of the management of pain in cancer survivors. In order to obtain the often-required behavioural change towards a more adaptive lifestyle, motivational interviewing can be used. To thoroughly tackle perceived injustice in patients having pain following cancer, special emphasis should be given to the individual reasons patients identify for experiencing (continued) pain and related symptoms. Pain acceptance should also be thoroughly addressed. Limitations: Clinical trials exploring the benefits, including cost-effectiveness, of such a multimodal approach in patients with pain following cancer treatment are needed. Conclusions: In light of its potential relevance for opioid abuse and potential impact on conservative management strategies, clinicians are advised to screen for perceived injustice in patients with pain following cancer treatment. Therapeutic targeting of perceived injustice can be done through an approach comprising of modified pain neuroscience education, motivational interviewing, and acceptance-based interventions. © 2021, American Society of Interventional Pain Physicians.
