Fatigue and cognitive fatigability in patients with chronic pain.

OBJECTIVES: Fatigue is common in patients with chronic pain. Still, there is a lack of studies examining objectively measurable cognitive aspects of fatigue: cognitive fatigability (CF). We aimed to investigate the presence of CF in patients with chronic pain and its relation to self-rated fatigue, attention, pain characteristics, sleep disturbance, depression, and anxiety. METHODS: Two hundred patients with chronic pain and a reference group of 36 healthy subjects underwent a comprehensive neuropsychological test battery, including measurement of CF with the Wechsler Adult Intelligence Scale-III Coding subtest, and self-assessment of trait and state fatigue. RESULTS: The patients with chronic pain did not show more CF as compared to the reference group. There was an association between CF and processing speed on a test of sustained and selective attention in the chronic pain group, while self-rated fatigue measures and pain characteristics were not associated with CF. Self-rated fatigue measures were highly correlated with self-rated pain intensity, spreading of pain, depression, anxiety, and sleep disturbance. CONCLUSIONS: The findings highlight the distinction between objective and subjective aspects of fatigue in chronic pain, and that the underlying causes of these different aspects of fatigue need to be studied further.

Interdisciplinary pain rehabilitation for patients with Ehlers-Danlos syndrome and hypermobility spectrum disorders.

OBJECTIVE: Chronic pain is a common manifestation of Ehlers-Danlos syndrome and hypermobility spectrum disorders; thus it is often suggested that patients undergo generic interdisciplinary pain rehabilitation, despite there being little evidence to support this decision. The aim of this study is to examine the effectiveness of standard rehabilitation programmes for chronic pain on patients with Ehlers-Danlos syndrome and hypermobility spectrum disorders, compared with patients with other chronic pain disorders. SUBJECTS: Data, collected between 2008 and 2016, were extracted from a Swedish national registry. The patient data comprised of 406 cases with Ehlers-Danlos syndrome or hypermobility spectrum disorders, 784 cases with a whiplash-related diagnosis, 3713 cases with diagnoses relating to spinal pain, and 2880 cases of fibromyalgia. METHODS: The differences between groups on key outcome measures from pre- to 1-year follow-up after interdisciplinary pain rehabilitation were analysed using linear mixed effects models. Sensitivity analysis in the form of pattern-mixture modelling was conducted to discern the impact of missing data. RESULTS: No significant differences were found in improvements from pre- to 1-year follow-up for patients with Ehlers-Danlos syndrome or hypermobility spectrum disorder compared with other diagnostic groups regarding measures of health-related quality of life, mental health, or fatigue. At follow-up, differences in pain interference (d = -0.34 (95% confidence interval [95% CI] -0.5 to -0.18)), average pain (d = 0.22 (95% CI 0.11-0.62)) and physical functioning (d = 2.19 (95% CI 1.61-2.77)) were detected for the group with spinal-related diagnoses in relation to those with EDS/HSD, largely due to pre-treatment group differences. Sensitivity analysis found little evidence for missing data influencing the results. CONCLUSION: This study suggests that patients with Ehlers-Danlos syndrome/hypermobility spectrum disorders may benefit from inclusion in an interdisciplinary pain rehabilitation programme.

Interdisciplinary pain rehabilitation for immigrants with chronic pain who need language interpretation.

OBJECTIVE: To investigate outcomes in patients with chronic pain after participation in an interdisciplinary pain rehabilitation programme with language interpreters, and to investigate the outcomes in women and men separately. DESIGN: Prospective multi-centre cohort study. PATIENTS: Ninety-five patients in Sweden with chronic pain who have insufficient knowledge of the Swedish language. METHODS: Duration and intensity of pain, anxiety and depression, health-related quality of life and fear of movement were evaluated before and after the programme. Patients were compared with a reference group comprising Swedish-speaking patients participating in an ordinary interdisciplinary pain rehabilitation programme. RESULTS: Before the interdisciplinary pain rehabilitation programme with language interpreters, all variables except pain duration differed significantly to the detriment of the studied group. The studied group showed significant improvements after the interdisciplinary pain rehabilitation programme with language interpreters, with regards to pain intensity, depression and fear of movement. The reference group improved significantly for all variables. The women in the studied group showed significant improvements for the same variables as the whole group, while the men in the studied group did not improve in any of the variables. CONCLUSION: This study indicates that patients with chronic pain, and especially women, who have insufficient knowledge of Swedish seem to benefit from participating in an interdisciplinary pain rehabilitation programme with language interpreters. The result may be of value for the further development of rehabilitation programmes with language interpreters.

Acceptability of the eHealth Intervention Sustainable Worker Digital Support for Persons With Chronic Pain and Their Employers (SWEPPE): Questionnaire and Interview Study.

BACKGROUND: Sick leave and decreased ability to work are the consequences of chronic pain. Interdisciplinary pain rehabilitation programs (IPRPs) aim to improve health-related quality of life and participation in work activities, although implementing rehabilitation strategies at work after IPRPs can be difficult. Employers' knowledge about pain and the role of rehabilitation needs to be strengthened. The self-management of chronic pain can be improved through eHealth interventions. However, these interventions do not involve communicating with employers to improve work participation. To address this deficiency, a new eHealth intervention, Sustainable Worker Digital Support for Persons with Chronic Pain and Their Employers (SWEPPE), was developed. OBJECTIVE: This study aimed to describe the acceptability of SWEPPE after IPRPs from the perspective of patients with chronic pain and their employers. METHODS: This study included 11 patients and 4 employers who were recruited to test SWEPPE in daily life for 3 months after IPRPs. Data were collected using individual interviews at the end of the 3-month test period and questionnaires, which were completed when SWEPPE was introduced (questionnaire 1) and at a 3-month follow-up (questionnaire 2). Data were also collected on how often SWEPPE was used. Qualitative data were analyzed through a qualitative content analysis using an abductive approach. The framework used for the deductive approach was the theoretical framework of acceptability. Quantitative data were analyzed through descriptive statistics and the differences between the responses to questionnaires 1 and questionnaire 2 using the Wilcoxon signed rank test. RESULTS: Both patients and employers reported that SWEPPE increased their knowledge and understanding of how to improve work participation and helped them identify goals, barriers, and strategies for return to work. In addition, participants noted that SWEPPE improved employer-employee communication and collaboration. However, experiences and ratings varied among participants and the different SWEPPE modules. The acceptability of SWEPPE was lower in patients who experienced significant pain and fatigue. A high degree of flexibility and choice of ratings in SWEPPE were generally described as helpful. CONCLUSIONS: This study shows promising results on the user acceptability of SWEPPE from both patient and employer perspectives. However, the variations among patients and modules indicate a need for further testing and research to refine the content and identify the group of patients who will best benefit from SWEPPE.

Daily time management in dementia: qualitative interviews with persons with dementia and their significant others.

BACKGROUND: Persons with dementia encounter time-related problems and significant others often need to provide support in daily time management and use of time assistive technology (AT). Further research has been requested on how time AT for persons with dementia affects the situation of significant others. Moreover, there are a few previous qualitative studies on the experiences of time AT by persons with dementia. This study explores the experiences of persons with dementia and significant others in daily time management and their perceptions on how time AT affects everyday life. METHOD: Semi-structured interviews with persons with mild to moderate dementia (n = 6) and significant others (n = 9) were conducted three months after receiving prescribed time AT. Interviews were analysed using qualitative content analysis. RESULTS: A main category "Support by significant others is always part of daily time management", and three categories "Facing new challenges", "Using strategies to handle changes", and "Time assistive technology in daily life" illustrated that significant others provided support for daily time management in all phases of dementia. This support was often embedded in other kinds of support for emerging challenges. Support in time management was needed from an early stage in dementia, and responsibility for time management was gradually transferred to significant others. Time AT could support time orientation and were important for sharing the time management conducted by others but did not enable independent time management. CONCLUSIONS: Time-related assessments and interventions should be offered at an early stage of dementia to increase the possibility of maintaining daily time management skills. Using time AT to communicate time might increase agency and participation in daily occupations for persons with dementia. Given the central role of significant others for daily time management, the society needs to adequately support persons with dementia lacking support from significant others.

Healthcare Professionals' Perceptions of and Attitudes towards a Standardized Content Description of Interdisciplinary Rehabilitation Programs for Patients with Chronic Pain-A Qualitative Study.

Interdisciplinary pain rehabilitation (IPR) is a recommended treatment for people with chronic pain. An inadequate description of the content of IPR programs makes it difficult to draw conclusions regarding their effects. The purpose of this study was to describe the perceptions and attitudes of healthcare professionals toward a content description of IPR programs for patients with chronic pain. Individual interviews with healthcare professionals (n = 11) working in IPR teams in Sweden were conducted between February and May 2019. Analysis of the interviews resulted in a theme: interdisciplinary pain rehabilitation is a complex intervention, with three categories: limitations in the description of IPR programs; lack of knowledge about IPR and chronic pain; and facilitating and hindering factors for using the content description of IPR programs. Conclusion: Healthcare professionals perceived that IPR programs could be described through a general content description. A general content description could enhance the quality of IPR programs through a better understanding of their content and a comparison of different IPR programs. Healthcare professionals also expressed the importance of a content description being a guide rather than a steering document.

Cognitive and mental fatigue in chronic pain: cognitive functions, emotional aspects, biomarkers and neuronal correlates-protocol for a descriptive cross-sectional study.

INTRODUCTION: Chronic pain (CP) is one of the most frequently presenting conditions in health care and many patients with CP report mental fatigue and a decline in cognitive functioning. However, the underlying mechanisms are still unknown. METHODS AND ANALYSIS: This study protocol describes a cross-sectional study aimed at investigating the presence of self-rated mental fatigue, objectively measured cognitive fatigability and executive functions and their relation to other cognitive functions, inflammatory biomarkers and brain connectivity in patients with CP. We will control for pain-related factors such as pain intensity and secondary factors such as sleep disturbances and psychological well-being. Two hundred patients 18-50 years with CP will be recruited for a neuropsychological investigation at two outpatient study centres in Sweden. The patients are compared with 36 healthy controls. Of these, 36 patients and 36 controls will undergo blood sampling for inflammatory markers, and of these, 24 female patients and 22 female controls, between 18 and 45 years, will undergo an functional MRI investigation. Primary outcomes are cognitive fatigability, executive inhibition, imaging and inflammatory markers. Secondary outcomes include self-rated fatigue, verbal fluency and working memory. The study provides an approach to study fatigue and cognitive functions in CP with objective measurements and may demonstrate new models of fatigue and cognition in CP. ETHICS AND DISSEMINATION: The study has been approved by the Swedish Ethics Review Board (Dnr 2018/424-31; 2018/1235-32; 2018/2395-32; 2019-66148; 2022-02838-02). All patients gave written informed consent to participate in the study. The study findings will be disseminated through publications in journals within the fields of pain, neuropsychology and rehabilitation. Results will be spread at relevant national and international conferences, meetings and expert forums. The results will be shared with user organisations and their members as well as relevant policymakers. TRIAL REGISTRATION NUMBER: NCT05452915.

Work Interventions Within Interdisciplinary Pain Rehabilitation Programs (IPRP) - Frequency, Patient Characteristics, and Association with Self-Rated Work Ability.

Background: Interdisciplinary pain rehabilitation programs (IPRPs) help people with chronic pain improve their health and manage their work; however, the way IPRPs address sick leave could be improved. Although work interventions can be a part of IPRP, it is not well known how and to what extent. Aim: This study explores the frequency of work interventions and the characteristics of patients who participate in work interventions as part of IPRP at specialist pain rehabilitation departments in Sweden. In addition, this study explores the association between participation in work interventions and change in patients' self-rated work ability after IPRP. Methods: Data from the Swedish quality registry for pain rehabilitation (SQRP), which includes 3809 patients between 2016 and 2018, were analysed with descriptive statistics and regression analyses. Results: The results indicate a high participation rate in work interventions (90%). Some differences were evident concerning characteristics of patients who participated in different work interventions. The return-to-work (RTW) plan, the most frequently used work intervention, had the strongest association with change in self-rated work ability after IPRP. However, the effect sizes were small, and the initial score best explained the change. Furthermore, there were differences between employed and unemployed patients and employment had a positive association with change in self-rated work ability. Conclusion: More research is needed to understand IPRP's mechanisms and work interventions to support patients with chronic pain, reduce sick leave, and manage work. Employment status needs to be considered and interventions should be tailored to match the individual needs.

The effects of a 15-week physical exercise intervention on pain modulation in fibromyalgia: Increased pain-related processing within the cortico-striatal- occipital networks, but no improvement of exercise-induced hypoalgesia.

Dysfunctional top-down pain modulation is a hallmark of fibromyalgia (FM) and physical exercise is a cornerstone in FM treatment. The aim of this study was to explore the effects of a 15-week intervention of strengthening exercises, twice per week, supervised by a physiotherapist, on exercise-induced hypoalgesia (EIH) and cerebral pain processing in FM patients and healthy controls (HC). FM patients (n = 59) and HC (n = 39) who completed the exercise intervention as part of a multicenter study were examined at baseline and following the intervention. Following the exercise intervention, FM patients reported a reduction of pain intensity, fibromyalgia severity and depression. Reduced EIH was seen in FM patients compared to HC at baseline and no improvement of EIH was seen following the 15-week resistance exercise intervention in either group. Furthermore, a subsample (Stockholm site: FM n = 18; HC n = 19) was also examined with functional magnetic resonance imaging (fMRI) during subjectively calibrated thumbnail pressure pain stimulations at baseline and following intervention. A significant main effect of exercise (post > pre) was observed both in FM patients and HC, in pain-related brain activation within left dorsolateral prefrontal cortex and caudate, as well as increased functional connectivity between caudate and occipital lobe bordering cerebellum (driven by the FM patients). In conclusion, the results indicate that 15-week resistance exercise affect pain-related processing within the cortico-striatal-occipital networks (involved in motor control and cognition), rather than directly influencing top-down descending pain inhibition. In alignment with this, exercise-induced hypoalgesia remained unaltered.

Assessing time processing ability and daily time management in persons with dementia: Psychometric properties of three instruments.

INTRODUCTION: Persons with dementia experience time-related problems, but there is a lack of instruments evaluating their time processing ability and daily time management. This study aimed to evaluate the psychometric properties of the instruments KaTid®-Senior measuring time processing ability, and Time-S© Senior and Time-Proxy© measuring daily time management for persons with dementia. METHODS: Persons with dementia (n = 53) and their significant others (n = 49) participated in the study. Rasch analyses were used to evaluate the instruments' rating scale functioning; internal scale validity; person-response validity; unidimensionality; person-separation reliability; and internal consistency. Versions excluding items with poor fit to the Rasch model were also evaluated. RESULTS: Overall, the Rasch analyses showed acceptable psychometric properties. All instruments met the criteria for unidimensionality and the reliability was good. More challenging items should be added in KaTid-Senior for better targeting of persons with mild dementia. Person-response validity issues in Time-S Senior need to be addressed. CONCLUSION: The instruments can validly and reliably be used to assess time processing ability and daily time management in persons with dementia in clinical research and healthcare settings. In turn, this can contribute to the development of methods to compensate for impaired time processing ability and daily time management. The assessments can also increase the possibility of early detection of impaired time processing ability and daily time management, thereby facilitating adequate timing of interventions and enhanced occupational performance.

Healthcare professionals' experiences and perspectives of team-based interdisciplinary pain rehabilitation with immigrants requiring an interpreter. A qualitative study.

PURPOSE: There is a lack of knowledge about interprofessional rehabilitation for culturally diverse patients with chronic pain. This study explores experiences of healthcare professionals developing and working with rehabilitation with patients in need of an interpreter and their experience of working with interpreters. METHODS: Twelve healthcare professionals at two Swedish specialist rehabilitation centres were interviewed. Grounded theory principles were used for the data collection and analysis. RESULTS: The main category "Demanding and Meaningful Work" represents three concurrently interacting categories: "Frustration" includes the informants' doubts regarding the benefits of the rehabilitation, lack of care for patients and cultural dissonance between professionals and patients. "Challenges" describes problems in the rehabilitation work due to the need for interpreted mediated communication, the complexity in health status and social aspects among the patients. "Solutions" represents practical working methods and personal approaches developed by the informants for managing frustrations and challenges. CONCLUSIONS: The informants' frustration and challenges when working with a new group of patients, vulnerable and different in their preconceptions, led to new solutions in working methods and approaches. When starting a pain rehabilitation programme for culturally diverse patients, it is important to consider the rehabilitation team's need for additional time and support.IMPLICATIONS FOR REHABILITATIONHealthcare professionals who encounter immigrants with chronic pain need resources to develop their own skills in order to handle complex ethical questions as the patients represent a vulnerable patient group with many low status identitiesIn order to adapt rehabilitation programmes to patient groups with different languages and pre-understandings of chronic pain, there is a need for a team with specific qualities, i.e., close cooperation, an innovative atmosphere, time and also support from expertsFor appropriate language interpretation it is important to have a professional interpreter and a healthcare professional who are aware of and adopt the rules, possibilities and restrictions of interpretationThe rehabilitation of patients in need of language interpretation needs more time and organisation compared to the rehabilitation of patients who speak the national language.

Preliminary Findings on Cognitive Dysfunction in University-Educated Patients After Mild COVID-19 Disease.

Objective: To investigate cognitive functioning in patients with higher education having post COVID-19 condition. Design: Prospective cohort study. Setting: Outpatient rehabilitation clinic. Participants: Patients (N=38; mean age, 48.5y; 71% women) at the Cognitive Post COVID-19 Clinic at Danderyd University Hospital in Stockholm, Sweden, who sought health care because of self-experienced cognitive problems. All had at least 4 years of university education and an initially mild infection (ie, most were not hospital admitted, none were admitted to intensive care). Interventions: Not applicable. Main Outcome Measures: Cognitive test performance assessed with a comprehensive neuropsychological test battery including Information, Matrix Reasoning, Coding, and Digit Span from Wechsler's Adult Intelligence Scale-IV, Buschke Selective Reminding Test, Rey Complex Figure Test, Ruff 2&7, Color-Word Interference Test, Verbal Fluency, and Trail Making Test. The mean time between the infection and the assessment was 18 months. Results: Cognitive deficits were evident on tests of verbal learning and memory (Buschke Selective Reminding Test) and selective attention (Ruff 2&7). Approximately 50% of the participants had scores lower than 1 SD below the mean in the norm group on the measures of verbal learning and memory. When estimated premorbid cognitive functioning was accounted for, deficits were suggested in most cognitive domains. Conclusions: Post COVID-19 condition seems to be associated with cognitive deficits, even in patients with high education and an initially mild infection.

Swedish Chronic Pain Biobank: protocol for a multicentre registry and biomarker project.

INTRODUCTION: About 20% of the adult population have chronic pain, often associated with psychological distress, sick leave and poor health. There are large variations in the clinical picture. A biopsychosocial approach is used in investigation and treatment. The concept of personalised medicine, that is, optimising medication types and dosages for individual patients based on biomarkers and other patient-related factors, has received increasing attention in different diseases but used less in chronic pain. This cooperative project from all Swedish University Hospitals will investigate whether there are changes in inflammation and metabolism patterns in saliva and blood in chronic pain patients and whether the changes correlate with clinical characteristics and rehabilitation outcomes. METHODS AND ANALYSIS: Patients at multidisciplinary pain centres at University Hospitals in Sweden who have chosen to participate in the Swedish Quality Registry for Pain Rehabilitation and healthy sex-matched and age-matched individuals will be included in the study. Saliva and blood samples will be collected in addition to questionnaire data obtained from the register. From the samples, proteins, lipids, metabolites and micro-RNA will be analysed in relation to, for example, diagnosis, pain characteristics, psychological distress, body weight, pharmacological treatment and clinical rehabilitation results using advanced multivariate data analysis and bioinformatics. ETHICS AND DISSEMINATION: The study is approved by the Swedish Ethical Review Authority (Dnr 2021-04929) and will be conducted in accordance with the declaration of Helsinki.The results will be published in open access scientific journals and in popular scientific relevant journals such as those from patient organisations. Data will be also presented in scientific meetings, meeting with healthcare organisations and disseminated in different lecturers at the clinics and universities.

Evidence-based digital support during 1 year after an Interdisciplinary Pain Rehabilitation Programme for persons with chronic musculoskeletal pain to facilitate a sustainable return to work: a study protocol for a registry-based multicentre randomised controlled trial.

INTRODUCTION: Chronic musculoskeletal pain (CMSP) severely affects the individual's quality of life, functioning and ability to work, and comes with significant societal costs for sick leave and productivity loss. After rehabilitation, patients with CMSP often experience lack of support when responsibility for the return-to-work process is taken over by the employer. Therefore, we aim to evaluate the effectiveness of a digital support (Sustainable WorkEr digital support for Persons with chronic Pain and their Employers (SWEPPE)) for promoting a sustainable return-to-work for persons with CMSP and to facilitate the employers' supportive role and responsibilities in the process. METHODS AND ANALYSIS: In this registry-based multicentre randomised controlled trial, 360 patients with CMSP will be randomised to either receive the smartphone application SWEPPE (n=180) or to a control group (n=180). The intervention group will use SWEPPE for 1 year and the control group will not receive any intervention for return to work (RTW). Participants will be recruited from approximately 10 specialist and primary care level units connected to the Swedish National Quality Registry for Pain Rehabilitation providing Interdisciplinary Pain Rehabilitation Programmes (IPRP) for CMSP. Eligibility criteria are age 18-65 years and a need for support in RTW or continued support at work for creating a sustainable work situation. Baseline data will be collected when the participants have completed the IPRP. Final assessment will be performed after 12 months. The primary outcome will be a number of days with sickness cash benefit. Secondary outcomes and explanatory variables including important domains affected by CMSP such as health-related quality of life, functioning and work ability will be collected. ETHICS AND DISSEMINATION: The Swedish Ethics Review Board approved the study (Dnr 2020-01593, Dnr 2021-01854). The study findings will be disseminated through publication, national and international conferences, and meetings to be available for patients, healthcare providers or stakeholders. TRIAL REGISTRATION NUMBER: NCT05058547.

Associations between Time Processing Ability, Daily Time Management, and Dementia Severity.

This study investigated associations between time processing ability (TPA), daily time management (DTM), and dementia severity. Persons with dementia (PwDs) (n = 53) and their significant others (n = 49) participated in this cross-sectional study. Bivariate analyses were used to investigate associations between TPA and DTM and the dementia severity. Linear regression models were used to further predict the contribution of the subtests in the Mini Mental State Examination (MMSE) for TPA results. The results showed significant correlations between TPA and dementia severity, where visuospatial functions were the most highly correlated. TPA also showed a significant correlation to proxy-rated DTM. In addition, proxy-rated DTM was significantly correlated with dementia severity and PwDs' own self-ratings of their DTM. Knowledge of the association between TPA, dementia severity, and visuospatial functions can enable early detection of TPA impairments. For a comprehensive assessment of TPA and DTM, objective measures should be used in combination with self-ratings and proxy-ratings. The findings can be used in clinical research and healthcare settings to develop methods to compensate for impaired TPA and support DTM in PwDs.

Stakeholders' experience of collaboration in the context of interdisciplinary rehabilitation for patients with chronic pain aiming at return to work.

BACKGROUND AND PURPOSE: Chronic pain is a major reason for sick leave worldwide. Interdisciplinary pain rehabilitation programs (IPRPs), workplace interventions, and stakeholder collaboration may support patients in their return to work (RTW). Few studies have examined stakeholders' experiences of important components in the RTW rehabilitation process for patients with chronic pain, especially in the context of IPRP. This study explores and describes stakeholders' experiences with stakeholder collaboration and factors related to RTW for patients with chronic pain who have participated in IPRP. METHODS: Six focus groups, three pair and four individual interviews were conducted with a total of 28 stakeholder representatives from three societal and three health care stakeholders. Data were analyzed using qualitative content analysis. RESULTS: The participants revealed that stakeholder collaboration and a tailored RTW rehabilitation plan were important strategies although they noted that these strategies were not working sufficiently efficient as presently implemented. The different stakeholders' paradigms and organizational prerequisites were described as hindrances of such strategies and that the degree of tailoring depended on individual attitudes. CONCLUSIONS: More knowledge transfer and flexibility, clearer responsibilities, and better coordination throughout the RTW rehabilitation process may increase the efficiency of stakeholder collaboration and support for patients.Implications for rehabilitationStakeholders need to have a close dialogue initiated before IPRP to be able to reach consensus and shared decision making in the RTW rehabilitation plan throughout the RTW rehabilitation process.Individually tailored solutions based on a thorough assessment of each patient's work ability and context are identified during IPRP and shall be included in the shared RTW rehabilitation plan.The responsibilities of the stakeholders need to be clarified and documented in the RTW rehabilitation plan.The role of RCs should be developed to improve the coordination throughout the patients' RTW rehabilitation process.

Distinct aberrations in cerebral pain processing differentiating patients with fibromyalgia from patients with rheumatoid arthritis.

ABSTRACT: The current study used functional magnetic resonance imaging to directly compare disease-relevant cerebral pain processing in well-characterized patient cohorts of fibromyalgia (FM, nociplastic pain) and rheumatoid arthritis (RA, nociceptive pain). Secondary aims were to identify pain-related cerebral alterations related to the severity of clinical symptoms such as pain intensity, depression, and anxiety. Twenty-six patients with FM (without RA-comorbidity) and 31 patients with RA (without FM-comorbidity) underwent functional magnetic resonance imaging while stimulated with subjectively calibrated painful pressures corresponding to a pain sensation of 50 mm on a 100-mm visual analogue scale. Stimulation sites were at the most inflamed proximal interphalangeal joint in the left hand in patients with RA and the left thumbnail in patients with FM, 2 sites that have previously been shown to yield the same brain activation in healthy controls. The current results revealed disease-distinct differences during pain modulation in RA and FM. Specifically, in response to painful stimulation, patients with FM compared to patients with RA exhibited increased brain activation in bilateral inferior parietal lobe (IPL), left inferior frontal gyrus (IFG)/ventrolateral prefrontal cortex (vlPFC) encapsulating left dorsolateral prefrontal cortex, and right IFG/vlPFC. However, patients with RA compared to patients with FM exhibited increased functional connectivity (during painful stimulation) between right and left IPL and sensorimotor network and between left IPL and frontoparietal network. Within the FM group only, anxiety scores positively correlated with pain-related brain activation in left dorsolateral prefrontal cortex and right IFG/vlPFC, which further highlights the complex interaction between affective (ie, anxiety scores) and sensory (ie, cerebral pain processing) dimensions in this patient group.

Factors of importance for return to work, experienced by patients with chronic pain that have completed a multimodal rehabilitation program - a focus group study.

BACKGROUND AND PURPOSE: To reduce the individual, societal, and economic burden of the high sick leave rates due to chronic pain, it is essential to find effective strategies for increasing return to work (RTW). Although multimodal rehabilitation programs (MMRPs) may have positive effects on RTW, the results are inconsistent. This study explores the factors that contribute to decreasing sick leave and increasing RTW in patients with chronic pain who completed a MMRP. METHOD: Four focus groups and three individual interviews were conducted. In total, 18 patients were interviewed. All patients had chronic pain and had completed a MMRP. They were either employed or unemployed, either working to some degree or fully on sick leave. The data were analysed using qualitative content analysis. RESULTS: Three main categories were identified: Knowledge and understanding-prerequisites for tailored solutions; Individual adaptations-necessary but difficult to implement; and Stakeholder collaboration-needs improvement. CONCLUSION: The participants described a variety of facilitating and limiting factors that created complex prerequisites for RTW. This finding makes it clear that these patients need tailored interventions and strong collaboration among all stakeholders throughout the rehabilitation process. Tailored interventions and collaborations could improve the effectiveness of MMRPs.IMPLICATIONS FOR REHABILITATIONPatients with chronic pain need tailored solutions and adaptations based on their individual needs in the RTW rehabilitation process.To return to work, patients with chronic pain needs support to strengthen their selfconfidence and to be prepared with knowledge and strategies about their abilities and their rights and obligations in relation to the labour market.A well-designed and communicated RTW rehabilitation plan supports the patient in the RTW rehabilitation process.To improve the possibility for employees and employers to create a sustainable work situation, stakeholder reconciliation meetings should be held routinely over time to strengthen the transfer of knowledge and collaboration.

Virtual Reality Exercises in an Interdisciplinary Rehabilitation Programme for Persons with Chronic Neck Pain: a Feasibility Study.

OBJECTIVE: To investigate the feasibility of a virtual reality exercise intervention within an interdisciplinary rehabilitation programme for persons with chronic neck pain. The effects of the intervention on symptom severity, variables related to chronic neck pain, and patients' experience of exercises were assessed. METHODS: Nine women and 3 men participated in a 6-week virtual reality exercise intervention during an interdisciplinary rehabilitation programme. Symptom severity was rated before and after each session of virtual reality exercise, using questionnaires before and after the interdisciplinary rehabilitation programme, and questions about participants' experiences. RESULTS: Neck pain symptoms increased temporarily during the exercises, but no lasting deterioration was found after the interdisciplinary rehabilitation programme. Depression, pain interference, pain control, sleep and kinesiophobia improved significantly after the programme. Participants experienced that the virtual reality exercises increased motivation to exercise and provided a focus other than pain. However, the equipment was heavy; and exercising was tiring and reminded them of their challenges. CONCLUSION: This study indicates that virtual reality exercises as part of an interdisciplinary rehabilitation programme are feasible and safe for patients with chronic neck pain. Pain symptoms may increase temporarily during the exercises. Virtual reality exercises may support participants by increasing motivation to exercise and providing helpful feedback. Further research into the added value of virtual reality exercises in an interdisciplinary rehabilitation programme for patients with chronic neck pain is warranted.

Do quality of life, anxiety, depression and acceptance improve after interdisciplinary pain rehabilitation? A multicentre matched control study of acceptance and commitment therapy-based versus cognitive-behavioural therapy-based programmes.

OBJECTIVE: Interdisciplinary pain rehabilitation (IPR) usually employs a cognitive-behavioural therapeutic (CBT) approach. However, there is growing support for chronic pain treatments based on acceptance and commitment therapy (ACT). Most studies of ACT and CBT for chronic pain have evaluated their effects after psychological interventions, not after IPR. We compared the results of an ACT-based IPR programme with two CBT-based IPR programmes. METHODS: We used a retrospective multicentre pretest-posttest design with matched patient groups at three centres. Data were collected from the Swedish Quality Registry for Pain Rehabilitation before and after IPR participation. Participants completed the EQ-5D health-related quality of life questionnaire, the Chronic Pain Acceptance Questionnaire, (CPAQ) and the Hospital Anxiety and Depression Scale (HADS). Analyses were performed to compare the effects of the different interventions. RESULTS: Neither EQ-5D nor HADS depression scores were affected by the psychological approach used. The score changes on both CPAQ subscales (activity engagement and pain willingness) indicated significant improvements between admission and discharge at all centres. CONCLUSIONS: These findings indicate the effectiveness of using psychological approaches to manage chronic pain. Both CBT and ACT had a beneficial effect on most of the assessed health-related parameters.
