RESUMO
BACKGROUND: Systemic inflammation, particularly the elevation of interleukin-6 (IL-6), plays an important role in the maintenance and progression of knee osteoarthritis. Insomnia, being highly prevalent in knee osteoarthritis, is understood to be a risk factor for systemic inflammation. The present study examined if cognitive behavioral therapy for insomnia (CBT-I) would reduce circulating IL-6 levels to a larger extent than the active control condition via greater improvement in sleep maintenance disturbance at mid-treatment, among individuals with knee osteoarthritis and insomnia disorder. METHODS: This is an ancillary study (N = 64) from a larger double-blind, randomized, active controlled clinical trial. Serum IL-6 was measured at baseline, post-treatment, and 3- and 6-month follow-ups. Sleep was measured by daily sleep diaries. RESULTS: Overall, there was no significant IL-6 trajectory differences between CBT-I and the active control (p = .64). Compared to the active control, CBT-I demonstrated greater improvement in sleep maintenance disturbance at mid-treatment (p = .01), which, in turn, was significantly associated with lower levels of IL-6 at 3-month follow-up (p < .05). Sleep maintenance disturbance at mid-treatment did not significantly predict changes in IL-6 levels at post-treatment (p = .43) and 6-month follow-up (p = .90). CONCLUSIONS: Our study demonstrates that CBT-I can be efficacious in improving sleep maintenance disturbance among individuals with knee osteoarthritis and insomnia disorder. However, no convincing evidence was found that CBT-I can substantially reduce IL-6 levels via improvement in sleep. CBT-I alone may not be effective in reducing systematic inflammation in this clinical population. TRIAL REGISTRATION: NCT00592449.

Background: Adverse childhood experiences (ACEs) have been shown to negatively affect health in adulthood. Estimates of associations between ACEs and chronic painful conditions are lacking.Objectives: This systematic review and meta-analysis aimed to evaluate associations between exposure to ACEs and chronic pain and pain-related disability in adults.Methods: We searched 10 electronic databases from inception to February 2023. We included observational studies assessing associations between direct ACEs (childhood sexual, physical, emotional abuse, or neglect) alone or in combination with indirect ACEs (witnessing domestic violence, household mental illness), and adult chronic pain (≥3 months duration) and pain-related disability (daily activities limited by chronic pain). Pairs of reviewers independently extracted data and assessed study risks of bias. Random-effect models were used to calculate pooled adjusted odds ratios [aOR]. Tau square [T2], 95% prediction intervals [95%PI] and I2 expressed the amount of heterogeneity, and meta-regressions and subgroup meta-analyses investigated sources of heterogeneity (PROSPERO: CRD42020150230).Results: We identified 85 studies including 826,452 adults of which 57 studies were included in meta-analyses. Study quality was generally good or fair (n = 70). The odds of reporting chronic pain in adulthood were significantly higher among individuals exposed to a direct ACE (aOR, 1.45, 95%CI, 1.38-1.53). Individuals reporting childhood physical abuse were significantly more likely to report both chronic pain (aOR, 1.50, 95CI, 1.39-1.64) and pain-related disability (1.46, 95CI, 1.03-2.08) during adulthood. Exposure to any ACEs alone or combined with indirect ACEs significantly increase the odds of adult chronic painful conditions (aOR, 1.53, 95%CI, 1.42-1.65) and pain-related disability (aOR, 1.29; 95%CI, 1.01-1.66). The risk of chronic pain in adulthood significantly increased from one ACE (aOR, 1.29, 95%CI, 1.22-1.37) to four or more ACEs (1.95, 95%CI, 1.73-2.19).Conclusions: Single and cumulative ACEs are significantly associated with reporting of chronic pain and pain-related disability as an adult.
Previous meta-analyses highlighted the negative impact of adverse childhood experiences on physical, psychological, and behavioural health across the lifespan.We found exposure to any direct adverse childhood experience, i.e. childhood sexual, physical, emotional abuse, or neglect alone or combined, increased the risk of reporting chronic pain and pain-related disability in adulthood.The risk of reporting chronic painful disorders increased with increasing numbers of adverse childhood experiences.

BACKGROUND AND INTRODUCTION: Pain is a subjective phenomenon, that is often misunderstood and invalidated. Despite recent advances in health professional training, it remains unclear how students should be taught about the subjectivity of pain. This study explored how a novel teaching activity that integrated physiotherapy students' first-hand experiences with laboratory-induced pain could address this gap. OBJECTIVE: The study aimed to explore the experiences and perceptions of physiotherapy students in relation to a workshop where physiotherapy students experienced laboratory induced pain. METHODS: We used a descriptive qualitative research design. Eighteen students participated in interviews. Transcripts were analyzed using an inductive conventional content analysis. RESULTS: We identified four overarching themes: 1) First-hand pain experiences facilitated engagement in learning; 2) Reflecting on these personal and peer pain experiences helped students make sense of pain; 3) The learning activity helped students understand the inherent subjectivity and complexity of pain; and 4) Students saw benefits for clinical practice. CONCLUSION: Integrating first-hand pain experiences within entry-level physiotherapy training appears to have novel value in helping students understand pain subjectivity. Future research should use robust and controlled designs to explore how this novel approach can be used to facilitate further understanding and empathy within clinical interactions with people living with pain.
RESUMO
OBJECTIVE: This project aimed to develop a virtual intervention for vertebral fractures (VIVA) to implement the international recommendations for the nonpharmacological management of osteoporotic vertebral fractures and to test its acceptability and usability. METHODS: VIVA was developed in accordance with integrated knowledge translation principles and was informed by the Behavioral Change Wheel, the Theoretical Domains Framework, and the affordability, practicability, effectiveness and cost-effectiveness, acceptability, side effects/safety, and equity (APEASE) criteria. The development of the prototype of VIVA involved 3 steps: understanding target behaviors, identifying intervention options, and identifying content and implementation options. The VIVA prototype was delivered to 9 participants to assess its acceptability and usability. RESULTS: VIVA includes 7 1-on-1 virtual sessions delivered by a physical therapist over 5 weeks. Each session lasts 45 minutes and is divided in 3 parts: education, training, and behavioral support/goal setting. Four main themes emerged from the acceptability evaluation: perceived improvements in pain, increased self-confidence, satisfaction with 1-on-1 sessions and resources, and ease of use. All of the participants believed that VIVA was very useful and were very satisfied with the 1-on-1 sessions. Four participants found the information received very easy to practice, 4 found it easy to practice, and 1 found it somewhat difficult to practice. Five participants were satisfied with the supporting resources, and 4 were very satisfied. Potential for statistically significant improvements was observed in participants' ability to make concrete plans about when, how, where, and how often to exercise. CONCLUSION: VIVA was acceptable and usable to the participants, who perceived improvements in pain and self-confidence. IMPACT: The virtual implementation of the recommendations for the nonpharmacological management of vertebral fractures showed high acceptability and usability. Future trials will implement the recommendations on a larger scale to evaluate their effectiveness.

PURPOSE: To understand experiences and perceptions on non-pharmacological treatment of vertebral fractures and virtual-care from the perspective of care professionals' (HCPs). DESIGN AND SETTING: We conducted semi-structured interviews with 13 HCPs within Canada (7 F, 6 M, aged 46 ± 12 years) and performed a thematic and content analysis from a post-positivism perspective. RESULTS: Two themes were identified: acuity matters when selecting appropriate interventions; and roadblocks to receiving non-pharmacological interventions. We found that treatment options were dependent on the acuity/stability of fracture and were individualized accordingly. Pain medication was perceived as important, but non-pharmacological strategies were also considered helpful in supporting recovery. Participants discussed barriers related to the timely identification of fracture, referral to physiotherapy, and lack of knowledge among HCPs on how to manage osteoporosis and vertebral fractures. HCPs reported positive use of virtual-care, but had concerns related to patient access, cost, and comprehensive assessments. CONCLUSION: HCPs used and perceived non-pharmacological interventions as helpful and selected specific treatments based on the recency of fracture and patient symptoms. HCPs' also believed that virtual-care that included an educational component, an assessment by a physiotherapist, and an exercise group was a feasible alternative, but concerns exist and may require further evaluation.Implications for RehabilitationNon-pharmacological strategies in combination with pain medication may be a more effective strategy to support recovery than pain medication alone but should be informed by fracture acuity and patient symptoms.To improve access to physiotherapy and other non-pharmacological treatment options during the acute or chronic management of vertebral fractures, it may be worthwhile to explore the effectiveness and feasibility of virtual-care.
RESUMO
OBJECTIVES: To determine the absolute and relative within-session test-retest reliability of pressure pain threshold (PPT) and temporal summation of pain (TSP) at the low back and the forearm in individuals with chronic low back pain (CLBP) and to test the impact of different sequences of measurements on reliability metrics. MATERIALS AND METHODS: Twenty-eight adults with CLBP were recruited. Relative (intraclass correlation coefficient [ICC] and coefficient of variation) and absolute reliability (standard error of measurement and minimal detectable changes) were quantified at 4 sites (back: sacrum and lumbar erector spinae; wrist: hand dorsum and wrist flexors) for PPT and 2 sites (hand and low back) for TSP, for various sequences of measurements. RESULTS: Systematic differences were found between within test and retest for most PPT sequences at the lumbar erector spinae site and 1 TSP sequence (1-2-3) at back and hand sites, precluding reliability analyses for these data. Within-session PPT relative reliability was excellent at low back (ICC = 0.83 to 0.94) and wrist (ICC = 0.88 to 0.97) sites, whereas TSP showed good to excellent reliability at hand (ICC = 0.80 to 0.90) and low back (ICC = 0.73 to 0.89). In general, 2 and 3 measurements optimized absolute and relative reliability for TSP and PPT, respectively. DISCUSSION: Within-session reliability was generally excellent for PPT and TSP at the low back and hand sites among individuals with CLBP. We recommend using 3 measurements for PPT and 2 for TSP to optimize reliability. Caution is recommended when testing PPT of the painful lower back area since a systematic difference was present between the test and retest.

INTRODUCTION: Chronic pain represents a major health issue, affecting the physical and mental health of approximately one in five people worldwide. It is now widely recognized that health professionals should use interventions that meet the needs of people living with chronic pain. Therefore, physiotherapists should attend to patients' perceived needs regarding physiotherapy services, i.e. the needs that are perceived by patients themselves based on their beliefs, values, preferences and expectations. However, previous reviews have mainly focused on health professionals' and experts' evaluations of patients' needs, which may result in inadequate answers to these needs. Therefore, a better understanding of patients' perceived needs could lead to more ethical and higher quality physiotherapy services. OBJECTIVE: The aim of this scoping review is thus to explore what is known from the existing literature about the perceived needs of people living with chronic pain regarding physiotherapy services. METHODS: This scoping review will follow Arksey and O'Malley's six-step framework. Medline, Embase, CINHAL, and APA PsycINFO will be used to search the scientific literature. The grey literature will also be searched using Google Scholar, OpenGrey and ProQuest Dissertation & Theses Global (PQDTGlobal). Studies published in English and French will only be considered. Two independent reviewers will perform the selection and extraction processes. Descriptive statistics will be performed to characterize the included studies. Quantitative, qualitative and mixed methods studies will be analyzed and synthetized using convergent qualitative meta-integration. Thereby, we will use the seven steps for convergent qualitative meta-integration proposed by Frantzen and Fetters to transform, analyze and integrate the quantitative and qualitative data. INCLUSION CRITERIA: Included studies will describe the perceived needs of adults living with chronic pain regarding physiotherapy services. Studies focusing on the perspectives of health professionals and rehabilitation services other than physiotherapy will be excluded.

INTRODUCTION: Exercise is the most recommended treatment for chronic low back pain (CLBP) and is effective in reducing pain, but the mechanisms underlying its effects remain poorly understood. Exercise-induced hypoalgesia (EIH) may play a role and is thought to be driven by central pain modulation mechanisms. However, EIH appears to be disrupted in many chronic pain conditions and its presence in people with CLBP remains unclear. As people suffering from chronic pain often exhibit psychological factors and central sensitization symptoms influencing pain perception, EIH might be associated with these factors. OBJECTIVE: The aim of this study is to compare the level of EIH between participants with and without CLBP following back and wrist exercises and to assess the associations between EIH, psychological factors, and symptoms of central sensitization (using the central sensitization inventory - CSI) in CLBP. METHOD: Twenty-eight participants with CLBP and 23 without pain were recruited. Pressure pain thresholds (PPT) were measured at 4 sites (2 bony sites = capitate, S1|2 muscle sites = wrist flexors, lumbar erector spinae) before and after each of two exercises (wrist flexion and lumbar extension). Exercise-induced hypoalgesia was defined as percent change in PPT from pre- to post-exercise. Participants with CLBP also completed questionnaires to measure psychological factors (e.g., kinesiophobia, catastrophizing, anxiety, and self-efficacy) and symptoms of central sensitization (CSI), and correlations with EIH were calculated. RESULTS: After wrist exercise, EIH measured at the muscle sites was lower in the CLBP group compared with the pain-free group (p = 0.047) but no differences were found at bony sites (p = 0.49). No significant differences for EIH were observed following back exercise at muscle sites (p = 0.14) or at bony sites (p = 0.65). Exercise-induced hypoalgesia was not correlated with any psychological factors or with the CSI score. CONCLUSION: The lower EIH following wrist exercises may represent an alteration in pain modulation control in CLBP. However, psychological factors and central sensitization symptoms may not explain the differences observed.

BACKGROUND: A growing body of evidence has demonstrated the importance of implementing movement-evoked pain in conventional pain assessments, with a significant role for psychological factors being suggested. Whether or not to include these factors in the assessment of movement-evoked pain has not yet been determined. OBJECTIVES: The aim of this systematic review is to explore the association between psychological factors and movement-evoked pain scores in people with musculoskeletal pain. METHODS: For this systematic review with meta-analysis, four electronic databases (PubMed, Medline, WOS, and Scopus) were searched. Cross-sectional studies, longitudinal cohort studies, and randomized controlled trials investigating the association between movement-evoked pain and psychological factors in adults with musculoskeletal pain were considered. Meta-analysis was conducted for outcomes with homogeneous data from at least 2 studies. Fischer-Z transformations were used as the measure of effect. Quality of evidence was assessed using the National Institutes of Health's Quality assessment tool for observational cohort and cross-sectional studies and Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. RESULTS: Meta-analyses and grading the quality of evidence revealed moderate evidence for a relation between movement-evoked pain and depressive symptoms (Fisher-z=0.27; 95%CI: 0.17, 0.36; 5 studies (n=440)), pain-related fear (Fisher-z=0.35; 95%CI: 0.26, 0.44; 6 studies (n=492)), and pain catastrophizing (Fisher-z=0.47; 95%CI: 0.36, 0.58; 4 studies (n=312)) in people with musculoskeletal pain. CONCLUSIONS: Movement-evoked pain is weakly to moderately associated to depressive symptoms, pain-related fear, and pain catastrophizing in people with musculoskeletal pain.

BACKGROUND: Pain experience has a multidimensional nature. Assessment and treatment recommendations for pain conditions suggest clinicians use biopsychosocial approaches to treat pain and disability. The current pain research is overwhelmingly skewed towards the study of biological and psychological factors including interventions, whereas, cultural factors are often ignored. OBJECTIVE: The aims of this Masterclass is threefold: (1) to discuss cultural influences on pain, (2) to provide strategies for delivering appropriate pain education and exercises in culturally diverse people with chronic pain, and (3) to present challenges and future directions to clinicians and researchers. DISCUSSION: Cultural factors have a relevant influence on the way individuals experience and manage health and illness. Thus, people with different cultural experience perceive, respond, communicate and manage their pain in different ways. In this aspect, the contents of pain education should be presented using different culturally appropriate examples, metaphors, images, and delivery methods that may enhance the impact of the message. Efforts should be made to produce and spread culturally adapted evidence-based materials and resources. In addition, a culturally sensitive approach may help to introduce patients to graded activities, so that they can apply these strategies in culturally acceptable and meaningful ways. Future studies should investigate the effectiveness of culturally-adapted interventions in pain-related outcomes in different pain conditions in patients with different cultural backgrounds.

Background: The Canadian Pain Task Force recently advanced an action plan calling for improved entry-level health professional pain education. However, there is little research to inform the collaboration and coordination across stakeholders that is needed for its implementation. Aims: This article reports on the development of a stakeholder-generated strategic plan to improve pain education across all Canadian physiotherapy (PT) programs. Methods: Participants included representatives from the following stakeholder groups: people living with pain (n = 1), PT students and recent graduates (n = 2), educators and directors from every Canadian PT program (n = 24), and leaders of Canada's national PT professional association (n = 2). Strategic priorities were developed through three steps: (1) stakeholder-generated data were collected and analyzed, (2) a draft strategic plan was developed and refined, and (3) stakeholder endorsement of the final plan was assessed. The project was primarily implemented online between 2016 and 2018. Results: The plan was developed through five iterative versions. Stakeholders unanimously endorsed a plan that included five priorities focusing on uptake of best evidence across (1) national PT governance groups and (2) within individual PT programs; (3) partnering with people living with pain in pain education; (4) advocacy for the PT role in pain management; and (5) advancing pain education research. Conclusion: This plan is expected to help Canadian stakeholders work toward national improvements in PT pain education and to serve as a useful template for informing collaboration on entry-level pain education within other professions and across different geographic regions.
Contexte: Le Groupe d'étude canadien sur la douleur a récemment présenté un plan d'action appelant à améliorer la formation initiale des professionnels de la santé sur la douleur. Cependant, il y a peu de recherche pouvant alimenter la collaboration et la coordination entre les parties prenantes nécessaires à sa mise en Åuvre.Objectifs: Cet article rend compte de l'élaboration d'un plan stratégique généré par les parties prenantes pour améliorer la formation sur la douleur dans tous les programmes canadiens de physiothérapie.Méthodes: Les participants comprenaient des représentants des groupes de parties prenantes suivants : les personnes vivant avec la douleur (n = 1), les étudiants en physiothérapie et nouveaux diplômés (n = 2), les enseignants et les directeurs de chaque programme canadien de physiothérapie (n = 24) et les dirigeants de l'association professionnelle nationale des physiothérapeutes du Canada (n = 2). Les priorités stratégiques ont été élaborées en trois étapes : (1) les données générées par les parties prenantes ont été collectées et analysées, (2) un projet de plan stratégique a été élaboré et affiné, et (3) l'approbation du plan final par les parties prenantes a été évaluée. Le projet a été principalement mis en Åuvre en ligne entre 2016 et 2018.Résultats: Le plan a été élaboré en cinq versions itératives. Les parties prenantes ont approuvé à l'unanimité un plan qui comprenait cinq priorités axées sur l'adoption des meilleures données probantes (1) dans les groupes de gouvernance nationaux en physiothérapie et (2) au sein des programmes individuels de physiothérapie ; (3) l'établissement de partenariats avec les personnes vivant avec la douleur dans le cadre de la formation sur la douleur ; (4) le plaidoyer pour le rôle de la physiothérapie dans la prise en charge de la douleur; et (5) l'avancement de la recherche en matiére de formation sur la douleur.Conclusion: Ce plan devrait aider les parties prenantes canadiennes à améliorer la situation à lé'chelle nationale en ce qui concerne la formation sur la douleur en physiothérapie et servir de modéle pour alimenter la collaboration dans le cadre de la formation initiale sur la douleur dans d'autres professions et dans différentes régions géographiques.
RESUMO
PURPOSE: The purpose of the present study was to conduct a preliminary evaluation of the feasibility and impact of a risk-targeted behavioral activation intervention for work-disabled individuals with comorbid pain and depression. METHODS: The design of the study was a single-arm non-randomized trial. The sample consisted of 66 work-disabled individuals with comorbid pain and depression. The treatment program consisted of a 10-week standardized behavioral activation intervention supplemented by techniques to target two psychosocial risk factors for delayed recovery, namely, catastrophic thinking and perceptions of injustice. Measures of pain severity, depression, catastrophic thinking, perceived injustice, and self-reported disability were completed pre-, mid-, and post-treatment. Satisfaction with treatment was assessed at post-treatment. Return to work was assessed at 6-month follow-up. RESULTS: The drop-out rate was 18%. At treatment termination, 91% of participants indicated that they were "very" or "completely" satisfied with their involvement in the treatment program. Significant reductions in pain (Cohen's d = 0.71), depression (d = 0.86), catastrophic thinking (d = 1.1), and perceived injustice (d = 1.0) were observed through the course of treatment. In multivariate analyses, treatment-related reductions in depression, catastrophic thinking, and perceived injustice, but not pain, contributed significant unique variance to the prediction of return-to-work outcomes. CONCLUSIONS: Risk-targeted behavioral activation was found to be an acceptable and effective intervention for work-disabled individuals with comorbid pain and depression. The findings suggest that interventions targeting psychosocial risk factors for pain and depression might contribute to more positive recovery outcomes in work-disabled individuals with comorbid pain and depression. TRIAL REGISTRATION: ClinicalTrials.gov: NCT0517442 . Retrospectively registered.
RESUMO
BACKGROUND: National strategies from North America call for substantive improvements in entry-level pain management education to help reduce the burden of chronic pain. Past work has generated a valuable set of interprofessional pain management competencies to guide the education of future health professionals. However, there has been very limited work that has explored the development of such competencies for individual professions in different regions. Developing profession-specific competencies tailored to the local context is a necessary first step to integrate them within local regulatory systems. Our group is working toward this goal within the context of entry-level physiotherapy (PT) programs across Canada. AIMS: This study aimed to create a consensus-based competency profile for pain management, specific to the Canadian PT context. METHODS: A modified Delphi design was used to achieve consensus across Canadian university-based and clinical pain educators. RESULTS: Representatives from 14 entry-level PT programs (93% of Canadian programs) and six clinical educators were recruited. After two rounds, a total of 15 competencies reached the predetermined endorsement threshold (75%). Most participants (85%) reported being "very satisfied" with the process. CONCLUSIONS: This process achieved consensus on a novel pain management competency profile specific to the Canadian PT context. The resulting profile delineates the necessary abilities required by physiotherapists to manage pain upon entry to practice. Participants were very satisfied with the process. This study also contributes to the emerging literature on integrated research in pain management by profiling research methodology that can be used to inform related work in other health professions and regions.
Contexte: Contexte: Les stratégies nationales nord-américaines préconisent des améliorations sensibles à la formation de base en matiére de prise en charge de la douleur afin de contribuer à la réduction du fardeau de la douleur chronique. Des travaux antérieurs ont généré un ensemble de compétences interprofessionnelles utile en matiére de prise en charge de la douleur afin de guider la formation des futurs professionnels de la santé. Cependant, trés peu de travaux ont porté sur l'acquisition de telles compétences pour des professions individuelles dans différentes régions. L'uisition de compétences spécifiques à une profession adaptées au contexte local est une première étape nécessaire pour leur intégration dans les systèmes réglementaires locaux. Notre groupe travaille à cet objectif dans le cadre de programmes de formation de base en physiothèrapie partout au Canada.Objectifs: Cette étude visait à créer un profil de compétences consensuel pour la prise en charge de la douleur, propre au contexte canadien de la physiothérapie.Méthodes: Un devis Delphi modifié a étè utilisé pour parvenir à un consensus parmi des formateurs en milieu universitaire et clinique en matière de douleur en milieu universitaire et clinique.Résultats: Des représentants de 14 programmes de formation de base en physiothérapie (93 % des programmes canadiens) et de six formateurs en milieu clinique ont été recrutés. Après deux tours, 15 compétences ont atteint le seuil d'approbation prédéterminé (75 %). La plupart des participants (85 %) ont déclaré être « très satisfaits ¼du processus.Conclusions: Ce processus a permis de dégager un consensus sur un nouveau profil de compétences en matiére de prise en charge de la douleur propre au contexte canadien de la physiothérapie. Ce profil délimite les habiletés requises des physiothérapeutes pour prendre en charge la douleur en début de pratique. Les participants ont été très satisfaits du processus. Cette étude contribue également à la littérature émergente sur la recherche intégrée en matière de prise en charge de la douleur en définissant une méthodologie de recherche qui peut être utilisée pour éclairer des travaux similaires dans d'autres professions de la santé et dans d'autres régions.
RESUMO
Suffering holds a central place within pain research, theory, and practice. However, the construct of pain-related suffering has yet to be operationalized by the International Association for the Study of Pain and is largely underdeveloped. Eric Cassell's seminal work on suffering serves as a conceptual anchor for the limited pain research that specifically addresses this construct. Yet, important critiques of Cassell's work have not been integrated within the pain literature. This Focus Article aims to take a preliminary step towards an updated operationalization of pain-related suffering by 1) presenting key attributes of pain-related suffering derived from a synthesis of the literature and 2) highlighting key challenges associated with Cassell's conceptualization of suffering. We present 4 key attributes: 1) pain and suffering are inter-related, but distinct experiences, 2) suffering is a subjective experience, 3) the experience of suffering is characterized by a negative affective valence, and 4) disruption to one's sense of self is an integral part of suffering. A key outstanding challenge is that suffering is commonly viewed as a self-reflective and future-oriented process, which fails to validate many forms of suffering and marginalizes certain populations. Future research addressing different modes of suffering - with and without self-reflection - are discussed. PERSPECTIVE: This article offers a preliminary step toward operationalizing the construct of pain-related suffering and proposes priorities for future research. A robust operationalization of this construct is essential to developing clinical strategies that aim to better recognize and alleviate suffering among people living with pain.

OBJECTIVE: Although pain-related fear and catastrophizing are predictors of disability in low back pain (LBP), their relationship with guarded motor behavior is unclear. The aim of this meta-analysis was to determine the relationship between pain-related threat (via pain-related fear and catastrophizing) and motor behavior during functional tasks in adults with LBP. METHODS: This review followed PRISMA guidelines. MEDLINE, Embase, PsychINFO, and CINAHL databases were searched to April 2021. Included studies measured the association between pain-related fear or pain catastrophizing and motor behavior (spinal range of motion, trunk coordination and variability, muscle activity) during movement in adults with nonspecific LBP. Studies were excluded if participants were postsurgery or diagnosed with specific LBP. Two independent reviewers extracted all data. The Newcastle-Ottawa Scale was used to assess for risk of bias. Correlation coefficients were pooled using the random-effects model. RESULTS: Reduced spinal range of motion during flexion tasks was weakly related to pain-related fear (15 studies, r = -0.21, 95% CI = -0.31 to -0.11) and pain catastrophizing (7 studies, r = -0.24, 95% CI = -0.38 to -0.087). Pain-related fear was unrelated to spinal extension (3 studies, r = -0.16, 95% CI = -0.33 to 0.026). Greater trunk extensor muscle activity during bending was moderately related to pain-related fear (2 studies, r = -0.40, 95% CI = -0.55 to -0.23). Pain catastrophizing, but not fear, was related to higher trunk activity during gait (2 studies, r = 0.25, 95% CI = 0.063 to 0.42). Methodological differences and missing data limited robust syntheses of studies examining muscle activity, so these findings should be interpreted carefully. CONCLUSION: This study found a weak to moderate relationship between pain-related threat and guarded motor behavior during flexion-based tasks, but not consistently during other movements. IMPACT: These findings provide a jumping-off point for future clinical research to explore the advantages of integrated treatment strategies that target both psychological and motor behavior processes compared with traditional approaches.

OBJECTIVES: Many people living with musculoskeletal pain conditions experience a range of negative biopsychosocial responses to physical activity, referred to as increased sensitivity to physical activity (SPA), that may undermine successful rehabilitation. This exploratory study aims to provide the first prospective analysis of the potential prognostic value of 3 biopsychosocial indices of SPA in relation to rehabilitation outcomes. This study also aimed to shed light on the cross-sectional interrelationships between these 3 biopsychosocial indices of SPA. MATERIALS AND METHODS: Adults with back pain were evaluated upon starting physical therapy and then again 3 months later. The initial testing session consisted of self-reported pain-related questionnaires and assessment of activity-related changes in pressure pain thresholds (SPA-Sensory), pain intensity ratings (SPA-Pain), and situational catastrophizing (SPA-Psych). The 3-month follow-up consisted of self-reported disability and pain questionnaires. Correlational and hierarchical linear regression analyses were conducted. RESULTS: A total of 97 participants completed both the initial visit and 3-month follow-up. The SPA-Pain index and the SPA-Psych index were significantly intercorrelated, but neither were correlated with the SPA-Sensory index. The SPA-Sensory index was not correlated with outcomes. The SPA-Pain index was correlated only with cross-sectional disability and pain outcomes. The SPA-Psych index was the only SPA index significantly correlated with outcomes both cross-sectionally and at 3-month follow-up. After controlling for baseline pain/disability and pain catastrophizing, SPA-Psych was no longer a significant prognostic factor for pain, but remained a significant prognostic factor for disability at 3-month follow-up (ß=0.272, t=2.674, P=0.008, R2 Δ=5.60%). DISCUSSION: This study highlights the importance of conceptualizing and measuring SPA as a biopsychosocial (rather than unidimensional) construct and points toward the added prognostic value of this construct. Implications for future research and practice are discussed.

OBJECTIVE: To determine the absolute and relative intra-rater within-session test-retest reliability of pressure pain threshold (PPT) and mechanical temporal summation of pain (TSP) at the low back and the forearm in healthy participants and to test the influence of the number and sequence of measurements on reliability metrics. METHODS: In 24 participants, three PPT and TSP measures were assessed at four sites (2 at the low back, 2 at the forearm) in two blocks of measurements separated by 20 minutes. The standard error of measurement, the minimal detectable change (MDC) and the intraclass correlation coefficient (ICC) were investigated for five different sequences of measurements (e.g. measurement 1, 1-2, 1-2-3). RESULTS: The MDC for the group (MDCgr) for PPT ranged from 28.71 to 50.56 kPa across the sites tested, whereas MDCgr for TSP varied from 0.33 to 0.57 out of 10 (numeric scale). Almost all ICC showed an excellent relative reliability (between 0.80 and 0.97), except when only the first measurement was considered (moderate). Although minimal differences in absolute PPT reliability were present between the different sequences, in general, using only the first measurement increase measurement error. Three TSP measures reduced the measurement error. DISCUSSION: We established that two measurements of PPT and three of TSP reduced the measurement error and demonstrated an excellent relative reliability. Our results could be used in future pain research to confirm the presence of true hypo/hyperalgesia for paradigms such as conditioned pain modulation or exercise-induced hypoalgesia, indicated by a change exceeding the measurement variability.
