Cognition is selectively impaired in males with spinal pain: A retrospective analysis of data from the Longitudinal Study of Ageing Danish Twins

Cognitive decline and spinal pain (back pain [BP] and neck pain [NP]) represent a major public health challenge, yet the potential relationship between them remains elusive. A retrospective analysis of the Longitudinal Study of Ageing Danish Twins was performed to determine any potential relationships between BP/NP and cognitive function adjusting for age, sex, educational and socioeconomic status. A total of 4731 adults (2788 females/1943 males) aged 78 ± 6 (SD) years were included in the analysis. We observed a 1-month prevalence of 25% with BP, 21% with NP and 11% for combined BP/NP. While there were no differences in cognition scores for males and females reporting combined BP/NP, compared to those without combined BP/NP (34.38 points [95% confidence interval (CI) = 31.88, 36.88] vs. 35.72 points [95% CI = 35.19, 36.26]; P = 0.180; and 35.72 points [95% CI = 35.19, 36.26] vs. 35.85 points [95% CI = 35.39, 36.31]; P = 0.327; for male and females, respectively), an adjusted analysis revealed that males with combined BP/NP presented with lower cognitive scores compared to males without combined BP/NP (81.26 points [95% CI = 73.80, 88.72] vs. 79.48 points [95% CI = 70.31, 88.66]; P = 0.043). The findings of this hypothesis-generating study may highlight a potential sex-specific association between spinal pain and later-life neurodegeneration.

EFFects of Exposure and Cognitive behavioral Therapy for chronic BACK pain ("EFFECT-BACK"): study protocol for a randomized controlled trial

INTRODUCTION

Chronic back pain is a widespread medical condition associated with high socioeconomic costs and increasing prevalence. Despite the advanced implementation of multidisciplinary approaches, providing a satisfactory treatment offer for those affected is often not possible. Exposure therapy (EXP) promises to be an effective and economical form of treatment and in a previous pilot study showed to be superior to cognitive behavioral therapy (CBT) in reducing perceived limitations of movement. The current study aims to further compare the efficacy of both treatment methods and identify those patient groups that particularly benefit from EXP.

METHODS

The general objective of this randomized multicenter clinical trial (targeted N = 380) is to improve and expand the range of treatments available to patients with chronic back pain. As the primary objective of the study, two different psychological treatments (EXP and CBT) will be compared. The primary outcome measure is a clinically significant improvement in pain-related impairment, measured by the QPBDS, from baseline to 6-month follow-up. Secondary outcome measures are absolute changes and clinically significant improvements in variables coping, psychological flexibility, depressiveness, catastrophizing, exercise avoidance and fear of exercise, and intensity of pain. Participants are recruited in five psychological and medical centers in Germany and receive ten sessions of manualized therapy by trained licensed CBT therapists or clinical psychologists, who are currently in their post-gradual CBT training. Potential predictors of each treatment's efficacy will be explored with a focus on avoidance and coping behavior.

CONCLUSION

This study will be the first RCT to compare CBT and EXP in chronic back pain in a large sample, including patients from different care structures due to psychological and medical recruitment centers. By identifying and exploring potential predictors of symptom improvement in each treatment group, this study will contribute to enable a more individualized assignment to treatment modalities and thus improves the care situation for chronic back pain and helps to create a customized treatment program for subgroups of pain patients. If our findings confirm EXP to be an efficacious and efficient treatment concept, it should gain more attention and be further disseminated.

'Engaging on a slightly more human level': A qualitative study exploring the care of individuals with back pain in a multidisciplinary pain clinic

Chronic low back pain is characterised by multiple and overlapping biological, psychological, social and broader dimensions, affecting individuals' lives. Multidisciplinary pain services have been considered optimal settings to account for the multidimensionality of chronic low back pain but have largely focused on cognitive and behavioural aspects of individuals' pain. Social dimensions are usually underexplored, considered outside or beyond healthcare professionals' scope of practice. Employing Actor Network Theorist Mol's concept multiplicity, our aim in this paper is to explore how a pain service's practices bring to the fore the social dimensions of individuals living with low back pain. Drawing on 32 ethnographic observations and four group exchanges with the service's clinicians, findings suggest that practices produced multiple enactments of an individual with low back pain. Although individuals' social context was present and manifested during consultations at the pain service (first enactment: 'the person'), it was often disconnected from care and overlooked in 'treatment/management' (second enactment: 'the patient'). In contrast, certain practices at the pain service not only provided acknowledgement of, but actions towards enhancing, individuals' social contexts by adapting rules and habits, providing assistance outside the service and shifting power relations during consultations (third enactment: 'the patient-person'). We therefore argue that different practices enact different versions of an individual with low back pain in pain services, and that engagement with individuals' social contexts can be part of a service's agenda.

The Roles of Depression, Life Control and Affective Distress on Treatment Attendance and Perceived Disability in Chronic Back Pain Sufferers throughout the Duration of the Condition

The aims of this study were to examine psychological factors that predict treatment seeking and disability over the total duration of experiencing back pain. A sample of 201 adults experiencing chronic back pain was recruited through health professionals and completed the Depression, Anxiety and Stress Scale (DASS), the Oswestry Back Pain Disability Questionnaire (ODQ), the McGill Pain Questionnaire (MPQ) and the life control and affective distress variables of the West Haven-Yale Multidimensional Pain Inventory (WHYMP), and participants disclosed the number of treatment sessions attended over the course of the illness. Depression, life control and affective distress were tested as indirect predictors of disability severity that were mediated by treatment attendance. Each unit increase in life control predicted attending nearly 30 more treatment sessions, each unit increase in affective distress predicted attending 16 fewer treatments and each unit increase in depression predicted 4 fewer treatments, together explaining 44% of variance in treatment seeking. The effects of life control and affective distress on disability were explained by treatment attendance, whereas depression retained a direct effect on disability. Treatment attendance had an effect on disability. The findings show that participants with lower life control and higher affective distress and depression had higher levels of pain and disability, in part due to due to their treatment-seeking behaviour.

Mechanisms of change in digital cognitive behavioral therapy for depression in patients with chronic back pain: A mediation analysis of a multicenter randomized clinical trial

BACKGROUND

While there is evolving knowledge on change processes of digital cognitive behavioral therapy (CBT) in the treatment of depression, little is known about how these interventions produce therapeutic change in the comorbid constellation of chronic back pain (CBP). Here, we examined whether the effects of a digital intervention to treat depression in patients with CBP are mediated by three pain-related variables (i.e., pain self-efficacy, pain-related disability, pain intensity).

METHODS

This study is a secondary analysis of a randomized clinical trial conducted in routine care at 82 orthopedic clinics across Germany. In total, 209 adults with CBP and diagnosed depression (SCID interview) were randomly assigned to the intervention (n = 104) or treatment-as-usual (n = 105). Cross-lagged mediation models were estimated to investigate longitudinal mediation effects of putative mediators with depression symptom severity (PHQ-9) as primary outcome at post-treatment.

RESULTS

Longitudinal mediation effects were observed for pain self-efficacy (ß = -0.094, 95%-CI [-0.174, -0.014], p = 0.021) and pain-related disability (ß = -0.068, 95%-CI [-0.130, -0.001], p = 0.047). Furthermore, the hypothesized direction of the mediation effects was supported, reversed causation did not occur. Pain intensity did not reveal a mediation effect.

CONCLUSIONS

The results suggest a relevant role of pain self-efficacy and pain-related disability as change processes in the treatment of depression for patients with CBP in routine care. However, further research is needed to disclose potential reciprocal relationships of mediators, and to extend and specify our knowledge of the mechanisms of change in digital CBT for depression.

Describing the nonsurgical, nonpharmacological interventions offered to adolescents with persistent back pain in randomized trials: A scoping review

BACKGROUND AND OBJECTIVES

Persistent nonspecific back pain is now established as a biopsychosocial phenomenon that can be meaningfully affected by individuals' cognitions, emotions, lifestyle factors and family and social relationships. Recent guidelines for the treatment of adolescents with persistent nonspecific back pain, as well as those for youth with mixed chronic pain, strongly recommend interdisciplinary care in which adolescents receive treatment for both mind and body. The objective of this scoping review was to examine the interventions evaluated in randomized trials for adolescents with persistent back pain to determine whether they correspond to these guidelines and to reveal future research priorities.

DATABASES AND DATA TREATMENT

The review protocol was registered in March 2022. We followed the PRISMA guidelines for scoping reviews. Twelve electronic databases were searched for relevant study reports. Data were charted on study characteristics, participant characteristics and intervention details using the Template for Intervention Description and Replication (TIDieR) checklist.

RESULTS

The search yielded 1952 records, of which eight reports representing seven randomized trials were eligible. The most common interventions were exercise therapy (n = 6) and back education (n = 4). Five studies employed multiple intervention components, but none was multidisciplinary. Studies primarily targeted posture or biomechanical factors. One study included an intervention addressing participants' fears and beliefs about pain.

CONCLUSIONS

Randomized trials for adolescents with persistent back pain have primarily relied upon an outdated, biomechanical explanation of persisting pain. Future randomized trials should align with current treatment recommendations and measure outcomes across multiple biopsychosocial domains.

SIGNIFICANCE

This scoping review describes in detail the interventions included in randomized trials for adolescents with persistent, nonspecific back pain. The review is important because it reveals discrepancies between those interventions and the interventions recommended for this population.

[Multiprofessional treatment approach in chronic back pain]

International guidelines recommend involving various professions and disciplines at an early stage in the event of chronic back pain. In connection with this, terms such as multiprofessional or interprofessional interventions are often mentioned without a uniform idea of what they mean. This article is intended to provide an overview of multiprofessional interventions for patients with chronic back pain and the integration into a meaningful interdisciplinary and interprofessional multimodal treatment concept. This is illustrated in a biopsychosocial pillar model, which should be pursued for each patient individually.

Brain structure, psychosocial, and physical health in acute and chronic back pain: a UK Biobank study

ABSTRACT

Brain structure, psychosocial, and physical factors underpin back pain conditions; however, less is known about how these factors differ based on pain duration and location. We examined, cross-sectionally, 11,106 individuals from the UK Biobank who (1) were pain-free (n = 5616), (2) had acute back pain (n = 1746), (3) had chronic localised back pain (CBP; n = 1872), or (4) had chronic back pain and additional chronic pain sites (CWP; n = 1872). We found differences in structural brain measures in the chronic pain groups alone. Both CBP and CWP groups had lower primary somatosensory cortex {CBP mean difference (MD) (95% confidence interval [CI]): -250 (-393, -107) mm3, P < 0.001; CWP: -170 (-313, -27)mm3, P = 0.011} and higher caudate gray matter volumes (CBP: 127 [38,216]mm3, P = 0.001; CWP: 122 [33,210]mm3, P = 0.002) compared with pain-free controls. The CBP group also had a lower primary motor cortex volume (-215 [-382, -50]mm3, P = 0.005), whereas the CWP group had a lower amygdala gray matter volume (-27 [-52, -3]mm3, P = 0.021) compared with pain-free controls. Differences in gray matter volumes in some regions may be moderated by sex and body mass index. Psychosocial factors and body mass index differed between all groups and affected those with widespread pain the most (all, P < 0.001), whereas grip strength was only compromised in individuals with widespread pain (-1.0 [-1.4, -0.5] kg, P < 0.001) compared with pain-free controls. Longitudinal research is necessary to confirm these interactions to determine the process of pain development in relation to assessed variables and covariates. However, our results suggest that categorised pain duration and the number of pain sites warrant consideration when assessing markers of brain structure, psychosocial, and physical health.

"Doctor, my back hurts and I cannot sleep." Depression in primary care patients: Reasons for consultation and perceived depression stigma

Background

General practitioners (GPs) play a significant role in depression care. Recognition of depression is crucial for adequate treatment but is impeded by a high portion of depressed patients only reporting physical symptoms to their GP. Among the many reasons for this phenomenon is mental health stigma. We investigated how patients with depression differed from patients without depression regarding the types and number of complaints presented to their GP, as well as their depression stigma. For the subgroup of patients with depression, potential associations between perceived depression stigma and number and types of presented complaints were investigated to see if these might reflect the patient’s intention to conceal mental health symptoms due to fear of being stigmatized by others. Further, we investigated if perceived depression stigma is related to depression treatment.

Methods

Data on depressive symptoms (assessed by the Depression Screening Questionnaire; DSQ), depression stigma (assessed by the Depressions Stigma Scale; DSS), type of complaints reported to the GP and treatment-related factors were collected from 3,563 unselected primary care patients of 253 GPs in a cross-sectional epidemiological study (“VERA study”) in six different German regions. Data of a total of 3,069 patients was used for analysis on complaints reported to the GP (subsample of the VERA study), and for 2,682 out of 3,069 patients data on a stigma questionnaire was available.

Results

Nearly half of the primary care patients with depression (42.2%) reported only physical complaints to their GP. Compared to patients without a depression diagnosis, patients with depression reported twice as many complaints to their GP with a mean of 2.02 (1.33) vs. 1.2 (0.69), including a more frequent combination of physical and mental symptoms (28.8% vs. 3.5%). Patients with depression showed higher total stigma compared to patients without depression, Mdn = 48 (IQR 40–54) vs. Mdn = 46.3 (IQR 29–53), due to higher perceived stigma, Mdn = 27 (IQR 21–32) vs. Mdn = 25.9 (IQR 20–29). Perceived stigma was associated with male gender (beta -.14, p = .005) and a lack of pharmacological treatment (beta -.14, p = .021) in patients with a depression diagnosis.

Conclusion

The number of complaints presented to the GP might function as a marker to actively explore depression in primary care patients, in particular when both physical and mental symptoms are reported. Perceived depression stigma should also be addressed especially in male patients. Further research should clarify the role of perceived stigma as a potential inhibitor of pharmacological treatment of depression in primary care.

Cross-sectional study of psychosocial and pain-related variables among patients with chronic pain during a time of social distancing imposed by the coronavirus disease 2019 pandemic

ABSTRACT

The COVID-19 pandemic has had a tremendous impact, including on individuals with chronic pain. The social distancing policies necessary to slow the spread of SARS-CoV-2 have involved increased levels of social isolation. This cross-sectional survey study examined pain severity and interference among individuals with chronic pain during an early phase of social distancing mandates and identified characteristics of individuals who were most impacted. Approximately 4 to 8 weeks after social distancing mandates commenced in the state of Massachusetts, 150 patients with fibromyalgia, chronic spine, and postsurgical pain completed demographic, pain, social distancing, and validated psychosocial questionnaires. Patients self-reported an overall significant increase in pain severity and pain interference, compared with before social distancing, although both pain severity and interference were quite variable among individuals under conditions of social distancing. Several demographic, socioeconomic, and psychosocial factors were associated with greater pain severity and interference during social distancing. Multivariable linear regression demonstrated that female sex, nonwhite race, lower education, disability, fibromyalgia, and higher pain catastrophizing were independently associated with greater pain severity, while female sex and pain catastrophizing were independently associated greater pain interference. The findings suggest that individual differences among patients with chronic pain should be considered in the planning, development, and prioritization of interventions to improve pain care and to prevent worsening of symptoms during the continuing COVID-19 pandemic.

Rates, costs and determinants of lumbar spine imaging in population-based women born in 1973-1978: Data from the Australian Longitudinal Study on Women's Health

Objective

There are concerns that lumbar spine imaging represents low value care. Our aim was to examine the use of lumbar spine imaging [radiography, computed tomography (CT), magnetic resonance imaging (MRI)] over 20 years, and costs and person-level characteristics of imaging in a large cohort of Australian women.

Methods

The Australian Longitudinal Study on Women’s Health (ALSWH) is a longitudinal population-based survey of women randomly selected from national health insurance scheme (Medicare) database. This study examined 13458 women born in 1973–1978 who consented to link their ALSWH and Medical Benefits Scheme records. Self-reported data on demographics, body mass index, depression, physical and mental health, and back pain were collected in each survey performed in 1996, 2000, 2003, 2006, 2009, 2012, and 2015. Data on lumbar spine imaging from 1996 to 2015 were obtained from the Medical Benefits Scheme database.

Results

38.9% of women underwent some form of lumbar spine imaging over 20 years. While radiography increased from 1996 to 2011 and decreased thereafter, CT and MRI continued to increase from 1996 to 2015. In women with self-reported back pain, depression and poorer physical health were associated with imaging, with no significant differences in types of imaging. Based on imaging rates in ALSWH, the estimated costs for Australian women aged 30–39 years were AU$51,735,649 over 2011–2015.

Conclusions

Lumbar spine imaging was common in population-based Australian women, with rates increasing over 20 years. Depression and poor physical health were associated with lumbar spine imaging. Raising awareness of this in clinicians is likely to result in significant cost savings if clinical guidelines are followed, with the potential of freeing resources for high value care and health outcomes.

Better Outcomes for Older people with Spinal Trouble (BOOST) trial: statistical analysis plan for a randomised controlled trial of a combined physical and psychological intervention for older adults with neurogenic claudication

BACKGROUND

Neurogenic claudication is a common spinal condition affecting older adults that has a major effect on mobility and implicitly independence. The effectiveness of conservative interventions in this population is not known. We describe the statistical analysis plan for the Better Outcomes for Older people with Spinal trouble (BOOST) randomised controlled trial.

METHODS/DESIGN

BOOST is a pragmatic, multicentre, parallel, two-arm, randomised controlled trial. Participants are community-dwelling adults, 65 years or older, with neurogenic claudication, registered prospectively, and randomised 2:1 (intervention to control) to the combined physical and psychological BOOST group physiotherapy programme or best practice advice. The primary outcome is the Oswestry Disability Index at 12 months. Secondary outcomes include the Short Physical Performance Battery, Swiss Spinal Stenosis Scale, 6 Minute Walk Test, Fear Avoidance Beliefs Questionnaire, and Tilburg Frailty Indicator. Outcomes are measured at 6 and 12 months by researchers blinded to treatment allocation. The primary statistical analysis is by intention to treat. Further study design details are published in the BOOST protocol.

DISCUSSION

The planned statistical analyses for the BOOST trial aim to reduce the risk of outcome reporting bias from prior data knowledge. Any changes or deviations from this statistical analysis plan will be described and justified in the final study report.

TRIAL REGISTRATION

This study has been registered in the International Standard Randomised Controlled Trial Number registry, reference number ISRCTN12698674 . Registered on 10 November 2015.

Emerging Clinical Technology: Application of Machine Learning to Chronic Pain Assessments Based on Emotional Body Maps

Depression and anxiety co-occur with chronic pain, and all three are thought to be caused by dysregulation of shared brain systems related to emotional processing associated with body sensations. Understanding the connection between emotional states, pain, and bodily sensations may help understand chronic pain conditions. We developed a mobile platform for measuring pain, emotions, and associated bodily feelings in chronic pain patients in their daily life conditions. Sixty-five chronic back pain patients reported the intensity of their pain, 11 emotional states, and the corresponding body locations. These variables were used to predict pain 2 weeks later. Applying machine learning, we developed two predictive models of future pain, emphasizing interpretability. One model excluded pain-related features as predictors of future pain, and the other included pain-related predictors. The best predictors of future pain were interactive effects of (a) body maps of fatigue with negative affect and (b) positive affect with past pain. Our findings emphasize the contribution of emotions, especially emotional experience felt in the body, to understanding chronic pain above and beyond the mere tracking of pain levels. The results may contribute to the generation of a novel artificial intelligence framework to help in the development of better diagnostic and therapeutic approaches to chronic pain.

Important work demands for reducing sickness absence among workers with neck or upper back pain: a prospective cohort study

BACKGROUND

The aim of this study was to investigate what exposure to work demands, physical and psychosocial, is associated with lower levels of sickness absence among workers with neck or upper back pain in different groups, by age, gender, duration of sickness absence and work ability score.

METHODS

This study was a prospective study of 4567 workers with neck or upper back pain. Data on neck or upper back pain, work demand and work ability were obtained from the Swedish Work Environment survey over a 3-year period (2009-2013). Register data on sickness absence, 1 year after each survey was conducted, were obtained from the Swedish health insurance database. Analyses were performed to estimate the association between self-reported work demands and registered sick days > 14 days. The analyses were stratified for gender, age group and work ability score.

RESULTS

Lower numbers of sick days were found for workers reporting low exposure to lifting ≥15 kg and twisted or forward-leaning work postures. Lower numbers of sick days were found for workers reporting high work control and seated work. The associations were generally stronger in the older age groups for the physical work demands.

CONCLUSIONS

The findings in this study suggest that certain physical work demands and having high control over one's work can result in lower sickness absence, especially among middle-aged and older workers with neck or upper back pain.

Outcomes and outcomes measurements used in intervention studies of pelvic girdle pain and lumbopelvic pain: a systematic review

Background

Pelvic girdle pain is a common problem during pregnancy and postpartum with significant personal and societal impact and costs. Studies examining the effectiveness of interventions for pelvic girdle pain measure different outcomes, making it difficult to pool data in meta-analysis in a meaningful and interpretable way to increase the certainty of effect measures. A consensus-based core outcome set for pelvic girdle pain can address this issue. As a first step in developing a core outcome set, it is essential to systematically examine the outcomes measured in existing studies.

Objective

The objective of this systematic review was to identify, examine and compare what outcomes are measured and reported, and how outcomes are measured, in intervention studies and systematic reviews of interventions for pelvic girdle pain and for lumbopelvic pain (which includes pelvic girdle pain).

Methods

We searched PubMed, Cochrane Library, PEDro and Embase from inception to the 11th May 2018. Two reviewers independently selected studies by title/abstract and by full text screening. Disagreement was resolved through discussion. Outcomes reported and their outcome measurement instruments were extracted and recorded by two reviewers independently. We assessed the quality of reporting with two independent reviewers. The outcomes were grouped into core domains using the OMERACT filter 2.0 framework.

Results

A total of 107 studies were included, including 33 studies on pelvic girdle pain and 74 studies on lumbopelvic pain. Forty-six outcomes were reported across all studies, with the highest amount (26/46) in the 'life impact' domain. 'Pain' was the most commonly reported outcome in both pelvic girdle pain and lumbopelvic pain studies. Studies used different instruments to measure the same outcomes, particularly for the outcomes pain, function, disability and quality of life.

Conclusions

A wide variety of outcomes and outcome measurements are used in studies on pelvic girdle pain and lumbopelvic pain. The findings of this review will be included in a Delphi survey to reach consensus on a pelvic girdle pain - core outcome set. This core outcome set will allow for more effective comparison between future studies on pelvic girdle pain, allowing for more effective translation of findings to clinical practice.

Back beliefs among elderly seeking health care due to back pain; psychometric properties of the Norwegian version of the back beliefs questionnaire

BACKGROUND

The Back Beliefs Questionnaire (BBQ) is a 14-item patient-reported questionnaire that measures attitudes and beliefs about the consequences of back pain. The BBQ has recently been translated into Norwegian, but its psychometric properties have not yet been tested. The aim of this study is to evaluate the reliability and construct validity of the BBQ when used on elderly patients with back pain.

METHOD

A prospective cohort study with a test-retest design among 116 elderly patients (> 55 years of age) seeking primary care for a new episode of back pain. Test-retest, standard error of measurement (SEM), minimal detectable change (MDC), internal consistency and construct validity by a priori hypotheses (Spearman's- and Pearson correlation coefficient) were tested.

RESULTS

A total of 116 patients, mean age (SD) 67.7 (8.3), were included and 63 patients responded to the test-retest assessment. The mean (SD) BBQ sum scores (range 9-45) were 29.8 (7.0) and 29.2 (6.7) for the test and retest respectively. The test-retest was acceptable with an intraclass correlation coefficient of 0.71 (95% CI, 0.54-0.82), SEM was 3.8 and MDC 10.5. Internal consistency with Cronbach's alpha was good (0.82) and acceptable construct validity was supported by the confirmation of 75% of the a priori hypotheses.

CONCLUSION

The Norwegian version of the BBQ demonstrated acceptable test-retest reliability and good construct validity and can be used to assess pessimistic beliefs in elderly patients with back pain.

Does Osteopathic Manipulative Treatment Make a Neuropsychological Difference in Adults With Pain? A Rationale for a New Approach

Cognitive impairment is common in patients with pain. While symptoms of pain are effectively treated with osteopathic manipulative treatment (OMT), the cognitive complaint is vastly ignored. Pain-induced cognitive dysfunction can be severe and is particularly apparent in working memory and attention. There is good reason to expect cognitive responsiveness to OMT. Previous research has reported the effects of OMT on related psychiatric outcomes, including relief from depression and anxiety, suggesting that OMT may produce more cortical benefits than is currently thought. The rationale to link OMT to cognition comes from the tenets of osteopathic medicine: body unity, homeostasis, and the structure-function relationship. The present article provides background evidence to support the hypothetical link between OMT and cognitive benefits and proposes a physiological mechanism of how OMT could exert its effect on cognition. Research strategies are discussed to test the hypotheses that are generated from the proposed theoretical framework.

Psychosocial Stress Reactivity as Predictor of Operative Outcome in Lumbar Disc Surgery

BACKGROUND

A large proportion of the population suffers from chronic back pain. For optimal treatment, the question arises which patients would benefit from conservative therapy and for whom lumbar disc surgery is most appropriate. It seems reasonable to analyze the impact of paraclinical parameters on the operation outcome to identify patients who would benefit less from surgery or need special pre-/postoperative medical care.

MATERIALS AND METHODS

From March 2012 to July 2014, 32 patients were treated via microscopically supported interlaminar fenestration and discectomy at the Department of Neurosurgery, University Hospital Carl Gustav Carus Dresden. One day before the operation, a cortisol survey was made during the stress response of the Trier Social Stress Test. At the same time, a survey of relevant questionnaires was conducted by which the postoperative symptom experience was made operational and comparable with the evaluation of the same information thirty days afterwards.

RESULTS

It could be shown that there is a connection between cortisol reactivity and the pain burden following operations. Patients with a greater cortisol reaction under stress exposition partially experienced more intense postoperative pain than the patients with a lower cortisol reaction. However, this relationship could only be explained by single significant results, whereas further calculations could not produce any significance.

CONCLUSIONS

Cortisol reactivity seems to be associated with pain development. The inconsistent findings in empiricism as well as in this investigation are indicative of a complex association of postoperative pain and cortisol reactivity, which needs to be examined further.

Prevalence of back pain and the knowledge of preventive measures in a cohort of 11619 Polish school-age children and youth-an epidemiological study

The study sought to characterize back pain (BP) (in the period of 12 months) in children and youth aged 10 to 19 from eastern Poland.The study included 11619 children and youth (6254 girls and 5365 boys) aged 10 to 19 from eastern Poland. An original questionnaire was applied as a research tool. Before the study, the reliability of the questionnaire had been assessed. The Kappa coefficient value for all the analyzed variables was equal to or higher than 0.91.Over 74.4% of the respondents admitted that within the last 12 months, they had experienced BP which was usually located in the lumbar spine (55.8%). The percentage of individuals reporting BP increased with age of participants. Girls reported BP more often than boys (82.8% vs 64.3%). The main circumstances in which BP occurred included lifting heavy objects, carrying school backpack and maintaining a sedentary position (70.7% vs 67.4% vs 67.8%). Over 67% of the respondents declared they did not know ergonomic principles.High prevalence of BP was noted. The declared BP was mainly located in the lumbar spine. Girls reported BP more often than boys. The students presented a very low level of knowledge about ergonomics. Therefore, the appropriate education should be included at school.

Do Religious Coping and Attachment to God Affect Perceived Pain? Study of the Elderly with Chronic Back Pain in Iran

Religious Coping (RC) refers to the individual's ability to understand and cope with the stress in life. Attachment is a God relatively stable emotional bond that forms through continuous communication and requires interaction, pleasure and relaxation. Considering the increasing population of the elderly and the role of pain in their health status, the present study was conducted aimed to determine the relationship between RC and attachment to God with perceived pain in the elderly with chronic low back pain (CLBP) in Ilam in Iran. The present study is a descriptive cross-sectional one in the elderly group with chronic low back pain in 2018. A total of 300 elderly patients with chronic low back pain were enrolled using convenience sampling. The tools used included demographic characteristics form, religious coping questionnaire, attachment to God's questionnaire and perceived pain intensity questionnaire. The findings indicated that the mean (SD) of the total score of attachment to God variables was 65.71 (2.64), religious coping was 20.67 (2.59), chronic pain acceptance was 17.29 (6.66), and perceived pain was 5.81 (2.65). Also, there was a meaningful correlation between the intensity of the pain and the level of attachment to God and religious coping. Therefore, it is suggested that appropriate religious interventions for elderly patients with chronic pain should be undertaken to reduce their pain status in order to help improve their quality of life.

The association between psychological and social factors and spinal pain in adolescents

Spinal pain, back pain, and/or neck pain begins early in life and is strongly associated with spinal pain in adulthood. Understanding the relationship between psychological and social factors and adolescent spinal pain may be important in both the prevention and treatment of spinal pain in this age group. We aimed to determine if psychological and social factors were associated with spinal pain in a cross-sectional study of a school-based cohort of 1279 Danish adolescents aged 11-13, who were categorized into "any" and "substantial" spinal pain. "Substantial spinal pain" was defined as a lifetime frequency of "sometimes" or "often" and a pain intensity of at least two on the revised Faces Pain Scale. Logistic regression analyses, stratified by sex, were conducted for single and all variables together. Eighty-six percent of participants reported "any spinal pain" and 28% reported "substantial spinal pain". Frequency of psychological and social factors was significantly higher in those with spinal pain compared to those without. As the frequency of psychological and social factors increased, the odds of both "any spinal pain" and "substantial spinal pain" also increased.Conclusion: Psychological and social factors may be important determinants in adolescent spinal pain. What is Known: • Spinal pain begins early in life to reach adult levels by age 18. Spinal pain in adolescence is strongly associated with spinal pain in adulthood. • In adults, psychological and social factors and spinal pain are strongly related; however, this relationship in adolescence is poorly understood. What is New: • Adolescents with spinal pain reported a significantly higher frequency of psychological factors and loneliness and lower levels of pupil acceptance. • Adolescents reporting higher levels of loneliness, lower levels of pupil acceptance, and increased frequency of psychological factors had increased odds of reporting "substantial spinal pain".

A comparison of professional and private time preferences of General Practitioners

In a perfect agency relationship, doctors consider all information and select the patient's 'utility maximising' option given the patient's preferences. The patient's time preferences are important as treatments vary in the timing and length of their benefits. However, doctors often do not have full information on patients' preferences and may apply their own preferences. This has generated empirical interest in estimating doctors' time preferences. However, these studies generally elicit doctors' private preferences (preferences for their own health) rather than professional preferences (preferences for the patient). We hypothesise that private and professional preferences may differ. Professional time preferences may be 'taught' in medical school or learned through repeated interactions with patients. If preferences differ then estimates of doctors' private preferences are less informative for medical decision-making. This study compares private and professional time preferences for health in a national sample of General Practitioners, using a between sample design. Time discounting is explored using exponential and quasi-hyperbolic models. We elicit time preferences using multiple price lists. We find no significant difference between the time preference for the self or the patient. This result holds for axiomatic discounting classification and maximum likelihood estimates. We do not find evidence of present-bias. There are a high proportion of increasingly impatient GPs, potentially implying a maximum 'willingness to wait' for treatment benefits. GPs value the health state differently between themselves or for a patient. These results suggest that we can use estimates of private preferences from doctors to inform medical decision-making.

The effect of spine discomfort on the overall postural (dis)comfort

Currently, the word 'comfort' is often used in relation to the marketing of products such as chairs, cars interiors, clothing, hand tools and even airplane tickets. In this field of research, the aim of this study is to investigate the influence of spinal posture on postural (dis)comfort perception; the test case is the analysis of the interaction between humans and vending machines for purchasing food or beverages. A statistical sample of 20 healthy students (subjects) performed the required tests, with each participant asked to take a product from three different vending machines (snacks, drinks and coffee). The subjects' postures were acquired non-invasively using cameras; software and instruments for virtual prototyping were used for posture analysis and interaction modelling, both questionnaires (subjective) and comfort-analysis software (objective) were used to rate the perceived (dis)comfort. The results obtained from simulations and questionnaires were compared, and a method to weigh the effect of the perceived spinal discomfort on overall postural (dis)comfort was proposed. These results reveal a good correlation between subjective perception and objective evaluation obtained through simulations, confirming the validity of the proposed method.

Can the STarT Back Tool predict health-related quality of life and work ability after an acute/subacute episode with back or neck pain? A psychometric validation study in primary care

OBJECTIVES

The predictive ability of the STarT Back Tool (SBT) has not yet been examined among acute/subacute back and/or neck pain in a primary care setting in respect to health-related quality of life (HRQoL) and work ability outcomes. The aim of this study was to evaluate the SBT's predictive validity for HRQoL and work ability outcomes at long-term follow-up in a population with acute/subacute back and/or neck pain.

SETTING

Prospective data from 35 primary care centres in south Sweden during 2013.

PARTICIPANTS

Patients (n=329) with acute/subacute back and/or neck pain, aged 18-67 years, not on sick leave or <60 days of sick leave completed the SBT when applying for physiotherapy treatment. Long-term follow-up measures (median 13 months, range 11-27 months) of HRQoL (EQ-5D) and work ability (Work Ability Score) was completed by 238 patients (72%).

OUTCOMES

The predictive ability of the SBT for HRQoL and work ability outcomes was examined using Kruskal-Wallis test, logistic regression and area under the curve (AUC).

RESULTS

Based on SBT risk group stratification, 103 (43%), 107 (45%) and 28 (12%) patients were considered as low, medium and at high risk, respectively. There were statistically significant differences in HRQoL (p<0.001) and work ability (p<0.001) at follow-up between all three SBT risk groups. Patients in the high risk group had a significantly increased risk of having poor HRQoL (OR 6.16, 95% CI 1.50 to 25.26) and poor work ability (OR 5.08, 95% CI 1.75 to 14.71) vs the low risk group at follow-up. The AUC was 0.73 (95% CI 0.61 to 0.84) for HRQoL and 0.68 (95% CI 0.61 to 0.76) for work ability.

CONCLUSIONS

The SBT is an appropriate tool for identifying patients with a poor long-term HRQoL and/or work ability outcome in a population with acute/subacute back and/or neck pain, and maybe a useful adjunct to primary care physiotherapy assessment and practice.

Back Pain – An Integrated Approach in Primary Care

Back pain is common, and although many cases remit quickly, a significant number also continue a relapsing course over many months and years. Psychosocial factors have a significant influence on the condition. The evidence from clinical trials of the effectiveness of various therapies is available in summarised form in several resources, though is often inconclusive. There is good evidence that acute back pain should be managed by staying active and using non-steroidal anti-inflammatory and analgesic drugs, adding cognitive behaviour therapy for subacute pain. For chronic back pain, exercise, pain management programmes, non-steroidal anti-inflammatory and analgesic drugs, and trigger point and ligament injections are also recommended. There appears to be increasing evidence in favour of the use of acupuncture. Acupuncture appears to be useful to treat back pain, but patients should probably be advised to take advantage of any pain relief obtained to maintain or increase their activity. Acupuncturists must be aware of the psychosocial dimensions of back pain, as well as the physical ones, and should be careful to educate their patients about the condition and not make them become dependent on acupuncture to treat every acute episode.

The Impact of Illness Perceptions and Coping on the Association Between Back Pain and Health Outcomes in Patients Suspected of Having Axial Spondyloarthritis: Data From the SPondyloArthritis Caught Early Cohort

OBJECTIVE

To investigate whether illness perceptions and coping influence the relationship between back pain and health outcomes in patients suspected of having axial spondyloarthritis (SpA).

METHODS

In the SPondyloArthritis Caught Early cohort, regression models were computed at baseline, with back pain intensity (range 0-10) as the determinant and health-related quality of life, the physical component summary score (PCS) and mental component summary (MCS) of the Short Form 36 (SF-36) health survey, or work productivity loss as outcomes. Subsequently, using Leventhal's Common-Sense Model of Self-Regulation, illness perceptions and, thereafter, coping were added to the models. Analyses were repeated for patients diagnosed and classified as having axial SpA according to the Assessment of SpondyloArthritis international Society axial SpA criteria (ASAS axial SpA), patients only diagnosed with axial SpA (axial SpA-diagnosed only), and those with chronic back pain.

RESULTS

A total of 424 patients (145 with ASAS axial SpA, 81 with only a diagnosis of axial SpA, and 198 with chronic back pain); 64% of the total group were female, the mean ± SD age was 30.9 ± 8.1 years, and the mean ± SD symptom duration was 13.3 ± 7.1 months) were studied. In all patients, the strength of the associations between back pain and the PCS, back pain and the MCS score, and back pain and loss of work productivity were decreased by adding illness perceptions to the model, but explained variance improved. Adding coping to these models did not change the results. Comparable results were observed in all subgroups.

CONCLUSION

Illness perception, but not coping, is important in the relationship between back pain and HRQoL and work productivity loss in patients suspected of having axial SpA, irrespective of subgroup. This finding suggests that targeting illness perceptions could improve health outcomes in patients suspected of having axial SpA.

The Management of Chronic Back Pain in Primary Care Settings: Exploring Perceived Facilitators and Barriers to the Development of Patient-Professional Partnerships

Supporting patients in forming partnerships with health professionals is the key of effective self-management. This study aimed to explore the nature of patient-professional partnerships and its related factors that create facilitators and barriers to patients' self-management ability. A constructivist grounded theory approach was undertaken. Three main themes emerged: interaction and communication, integrated care, and service and system. A theoretical model was generated that posits effective communication, individualized integrated care, and high-quality service as key influences on the successful development of patient-professional partnerships and patients' ability to self-manage. Giving attention to these factors helps understand the development, implementation, mechanisms, and evaluation of building a patient-professional partnership and maximizes the opportunities for patient self-management of chronic pain. Future research and practice are needed to move beyond a simplistic focus on health outcomes to address the complex links between partnerships and treatment delivery processes, and interventions, effects, and patients' context.

Effect of Pain Neuroscience Education Combined With Cognition-Targeted Motor Control Training on Chronic Spinal Pain: A Randomized Clinical Trial

Importance

Effective treatments for chronic spinal pain are essential to reduce the related high personal and socioeconomic costs.

Objective

To compare pain neuroscience education combined with cognition-targeted motor control training with current best-evidence physiotherapy for reducing pain and improving functionality, gray matter morphologic features, and pain cognitions in individuals with chronic spinal pain.

Design, Setting, and Participants

Multicenter randomized clinical trial conducted from January 1, 2014, to January 30, 2017, among 120 patients with chronic nonspecific spinal pain in 2 outpatient hospitals with follow-up at 3, 6, and 12 months.

Interventions

Participants were randomized into an experimental group (combined pain neuroscience education and cognition-targeted motor control training) and a control group (combining education on back and neck pain and general exercise therapy).

Main Outcomes and Measures

Primary outcomes were pain (pressure pain thresholds, numeric rating scale, and central sensitization inventory) and function (pain disability index and mental health and physical health).

Results

There were 22 men and 38 women in the experimental group (mean [SD] age, 39.9 [12.0] years) and 25 men and 35 women in the control group (mean [SD] age, 40.5 [12.9] years). Participants in the experimental group experienced reduced pain (small to medium effect sizes): higher pressure pain thresholds at primary test site at 3 months (estimated marginal [EM] mean, 0.971; 95% CI, -0.028 to 1.970) and reduced central sensitization inventory scores at 6 months (EM mean, -5.684; 95% CI, -10.589 to -0.780) and 12 months (EM mean, -6.053; 95% CI, -10.781 to -1.324). They also experienced improved function (small to medium effect sizes): significant and clinically relevant reduction of disability at 3 months (EM mean, -5.113; 95% CI, -9.994 to -0.232), 6 months (EM mean, -6.351; 95% CI, -11.153 to -1.550), and 12 months (EM mean, -5.779; 95% CI, -10.340 to -1.217); better mental health at 6 months (EM mean, 36.496; 95% CI, 7.998-64.995); and better physical health at 3 months (EM mean, 39.263; 95% CI, 9.644-66.882), 6 months (EM mean, 53.007; 95% CI, 23.805-82.209), and 12 months (EM mean, 32.208; 95% CI, 2.402-62.014).

Conclusions and Relevance

Pain neuroscience education combined with cognition-targeted motor control training appears to be more effective than current best-evidence physiotherapy for improving pain, symptoms of central sensitization, disability, mental and physical functioning, and pain cognitions in individuals with chronic spinal pain. Significant clinical improvements without detectable changes in brain gray matter morphologic features calls into question the relevance of brain gray matter alterations in this population.

Factors related to work ability and well-being among women on sick leave due to long-term pain in the neck/shoulders and/or back: a cross-sectional study

BACKGROUND

Musculoskeletal pain is one of the leading causes of sick leave, especially among women, in Western countries. The aim of the present study was to identify factors associated with work ability and well-being, respectively, among women on sick leave due to long-term pain in the neck/shoulders and/or back.

METHODS

A cross-sectional study with a correlational design was conducted on women who were sick-listed due to long-term pain in the neck/shoulders and/or back. A total of 208 participants responded to a survey comprising eight instruments: Multidimensional Pain Inventory scale, General Self-Efficacy scale, Sense of Coherence scale, Coping Strategies Questionnaire, Demand-Control-Support Questionnaire, Hospital Anxiety and Depression Scale, Work Ability Index and Life Satisfaction questionnaire. Multiple linear regression analyses were performed to identify factors associated with work ability and well-being, respectively.

RESULTS

Women who more strongly believed they would return to the same work had greater work ability (β = 0.39, p < 0.001), whereas women with higher pain intensity (β = - 0.30, p < 0.001) and higher job strain (β = - 0.12, p < 0.05) had lower work ability. Women with higher self-efficacy rated greater well-being (β = 0.14, p < 0.05). As the women's scores for depression increased, their well-being decreased by 48%, which was statistically significant (p < 0.001). The regression models for work ability and well-being were significant (p < 0.001), and their adjusted R- square values were 48% and 59%, respectively.

CONCLUSIONS

The study suggests that the factors beliefs to be back at the same work, pain intensity and job strain are predictive of work ability. Moreover, the factors self-efficacy and depression seem to be predictive of well-being. The findings highlight factors that should be considered by health care professionals and policy-makers to guide attempts to reduce sick leave.

Stress and Alterations in the Pain Matrix: A Biopsychosocial Perspective on Back Pain and Its Prevention and Treatment

The genesis of chronic pain is explained by a biopsychosocial model. It hypothesizes an interdependency between environmental and genetic factors provoking aberrant long-term changes in biological and psychological regulatory systems. Physiological effects of psychological and physical stressors may play a crucial role in these maladaptive processes. Specifically, long-term demands on the stress response system may moderate central pain processing and influence descending serotonergic and noradrenergic signals from the brainstem, regulating nociceptive processing at the spinal level. However, the underlying mechanisms of this pathophysiological interplay still remain unclear. This paper aims to shed light on possible pathways between physical (exercise) and psychological stress and the potential neurobiological consequences in the genesis and treatment of chronic pain, highlighting evolving concepts and promising research directions in the treatment of chronic pain. Two treatment forms (exercise and mindfulness-based stress reduction as exemplary therapies), their interaction, and the dose-response will be discussed in more detail, which might pave the way to a better understanding of alterations in the pain matrix and help to develop future prevention and therapeutic concepts.

Causal Relation of Psychical Stress to Acute Back Pain

PURPOSE OF THE STUDY There s a known relation between the chronical back-pain-syndrome and psychical problems. We suppose a direct causality between acute stress and onset of the backpain syndrome. MATERIAL AND METHODS A prospective cohort-study (IV/2014 - VIII/2014) of patients who came to our emergency department with acute backpain-syndrome, with no relevant previous history - such as operations or chronic pain. We questioned together 39 patients (19 female and 20 male). The patients filled in two charts: FW7, and also a modified HADS-D. In the later one the patients were questioned in two extra points regarding contingent excessive emotional or existential problems in their brief history. The Pain-Severity-Score was assessed as well. RESULTS Combined together, relevant score-results and / or anamnesis of excessive emotional or existential problem was found in 79.5% (SD 0.4%) of the whole cohort. CONCLUSIONS This could have implications for guidelines, introducing the psychotherapy-first into the concepts. Key words:stress; well-being; depression; back-pain-syndrome.

Effectiveness and cost-effectiveness of a guided internet- and mobile-based depression intervention for individuals with chronic back pain: protocol of a multi-centre randomised controlled trial

INTRODUCTION

Depression often co-occurs with chronic back pain (CBP). Internet and mobile-based interventions (IMIs) might be a promising approach for effectively treating depression in this patient group. In the present study, we will evaluate the effectiveness and cost-effectiveness of a guided depression IMI for individuals with CBP (eSano BackCare-D) integrated into orthopaedic healthcare.

METHODS AND ANALYSIS

In this multicentre randomised controlled trial of parallel design, the groups eSano BackCare-D versus treatment as usual will be compared. 210 participants with CBP and diagnosed depression will be recruited subsequent to orthopaedic rehabilitation care. Assessments will be conducted prior to randomisation and 9 weeks (post-treatment) and 6 months after randomisation. The primary outcome is depression severity (Hamilton Rating Scale for Depression-17). Secondary outcomes are depression remission and response, health-related quality of life, pain intensity, pain-related disability, self-efficacy and work capacity. Demographic and medical variables as well as internet affinity, intervention adherence, intervention satisfaction and negative effects will also be assessed. Data will be analysed on an intention-to-treat basis with additional per-protocol analyses. Moreover, a cost-effectiveness and cost-utility analysis will be conducted from a societal perspective after 6 months.

ETHICS AND DISSEMINATION

All procedures are approved by the ethics committee of the Albert-Ludwigs-University of Freiburg and the data security committee of the German Pension Insurance (Deutsche Rentenversicherung). The results will be published in peer-reviewed journals and presented on international conferences.

Health-care utilization of patients with chronic back pain before and after rehabilitation

BACKGROUND

Patients with chronic back pain show an increased use of health-care services leading to high direct costs. Multidisciplinary rehabilitation reduces pain intensity, depression, disability and work inability. The study aims to investigate whether health-care utilization in patients with chronic back pain is lower after rehabilitation than before rehabilitation and if, in addition to sociodemographic, medical and psychological characteristics, changes in these characteristics immediately after rehabilitation can predict health-care utilization.

METHODS

N = 688 patients with chronic back pain were asked about their overall health-care services use and the use of general practitioners, specialists, physiotherapy, psychotherapy, complementary therapist, massages, and admission to hospital both 6 months before and 6 months after rehabilitation. In addition, various sociodemographic, medical and psychological variables were assessed. To measure changes due to rehabilitation, differences in pain intensity, disability, impairment and coping, quality of life, and days on sick leave before and after rehabilitation were calculated. Dependent t-tests and hierarchical regression analyses were used to analyse the data.

RESULTS

Health-care utilization 6 months after rehabilitation was, except for physiotherapy and psychotherapy, significantly lower than before. The effect sizes were rather small (Cohens'd =. 01-.34). After rehabilitation between 15.2% and 39.9% of the variance of health-care utilization could be explained. The baseline values of health-care utilization explained between 3.2% and 15.9% of the incremental variances. The changes in psychological impairment and coping as well as in sick leave after rehabilitation could explain between 0.8% and 2.9% of the variance of health-care utilization after rehabilitation. Its influence was significant for the general use of health-care services, general practitioners and specialists.

CONCLUSIONS

The results indicate that use of health-care services after rehabilitation in the present study is slightly lower than before, which has an impact on direct costs due to chronic back pain in Germany. The predictors show the importance in terms of health-care utilization of improving work ability and psychological impairment.

When Words Fail: Psychosomatic Illness and The Talking Cure

This paper discusses psychosomatic illness as a disorder of the individual's subjectivity in relation, or a surrender of mind and mindfulness to the other. Illustrative clinical material highlights the usefulness of Harry Stack Sullivan's (I954) detailed inquiry in locating the psychosomatic patient's own voice in the consulting room. Particular attention is paid to the form and use of language to impede or foster private experience and personal agency.

Factors associated with return to work among people on work absence due to long-term neck or back pain: a narrative systematic review

OBJECTIVE

The purpose of this narrative systematic review was to summarise prognostic factors for return to work (RTW) among people with long-term neck/shoulder or back pain.

METHODS

A systematic literature search was performed through three databases (Medline, CINAHL and PsycINFO) for studies published until February 2016. Only observational studies of people on work absence (≥2 weeks) due to neck/shoulder or back pain were included. The methodological quality of the included studies was assessed using guidelines for assessing quality in prognostic studies on the basis of Framework of Potential Biases. Factors found in the included studies were grouped into categories based on similarities and then labelled according to the aspects covered by the factors in the category.

RESULTS

Nine longitudinal prospective cohort studies and one retrospective study fulfilled the inclusion criteria. From these, five categories of factors were extracted. Our findings indicate that recovery beliefs, health-related factors and work capacity are important for RTW among people with long-term neck or back pain. We did not find support for workplace factors and behaviour being predictive of RTW.

CONCLUSIONS

Our findings suggest that recovery beliefs, perceived health and work capacity may be important targets of intervention for people with long-term neck or back pain. However, more high-quality prospective studies are needed to confirm the results and improve our understanding of what is needed to facilitate RTW in this population.

A Model for Integrative Transformation: A Back Pain Group Appointment Program

A back pain treatment program was developed for the outpatient, primary care clinic setting. In this pilot study, measured functional status scores improved in a cohort of patients enrolled in the program. The program consists of a series of 5 monthly group appointments and follows a sequential curriculum involving multiple therapeutic modalities. These modalities include exercise, social interaction, motivation/raison d'être, holistic coaching, music, and behavioral modelling. The program provides a forum for the discussion and implementation of complementary and alternative approaches, alongside mainstream approaches, and represents a model of integrative medical practice.

Risk of major depressive disorder among older persons living in HIV-endemic central and southwestern Uganda

Major depressive disorder (MDD) is projected to become the second most common cause of disability by 2020 calling for a better understanding its antecedents across the lifespan and in diverse socio-cultural settings. In this paper we describe the risk factors of MDD among older people (50 years +) living in HIV-endemic central and southwestern Uganda. A cross-sectional study was undertaken among 471 respondents (50 years +) participating in the Wellbeing of Older People's Study cohort of the MRC/UVRI Uganda research Unit on AIDS in Uganda. Participants were from five strata: HIV negative, HIV positive on ART, HIV positive not on ART, having an adult child on ART, and having an adult child who died of HIV. Overall MDD prevalence was 9.2% (95% CI 6.7-12.2%) with a prevalence among males of 7.4% (95% CI 4.0-12.3%) and females of 10.3% (95% CI 7.0-14.3%). Factors significantly associated with MDD included: declining socio-economic status, increasing disability scores, decreasing mean grip strength, reported back pain, and not having hypertension. Marginally associated with MDD was being HIV infected and not on ART.

Prevalent musculoskeletal pain as a correlate of previous exposure to torture

Aim: To research possible associations between previous exposure to specific torture techniques and prevalent pain in the head and face, back, and feet. Methods: 221 refugees, 193 males and 28 females, previously exposed to torture in their home country, were subject to a clinical interview at a rehabilitation clinic for torture victims. The interview focused on exposure to torture and somatic symptoms prevalent at examination. Results: The mean number of times imprisoned was 2.3; the mean number of months imprisoned was 19.7; the mean duration from initial imprisonment to final release was 3.7 years; and the mean duration from final release to preliminary interview was 8.4 years. The most frequent physical torture method reported was beating (92.3%) and the main mental torture method was deprivation (84.6%). Pain in the head and face was found to be strongly associated with torture against head and face (OR 3.89, 95% CI 1.49—10.20) and with the cumulative number of physical torture methods exposed to. Pain in the back was associated with sexual torture (OR 2.75, 95% CI 1.07—7.12). Besides beating of the lower extremities (OR 5.98, 95% CI 2.47—14.48), the strongest predictor for pain in the feet was general abuse of the whole body (OR 5.64, 95% CI 1.93—16.45). Conclusion: In spite of many factors being potentially co-responsible for prevalent pain, years after the torture took place it presents itself as strongly associated with specific loci of pain, with generalized effects, and with somatizing.

Causal Attribution and Coping Maxims Differences between Immigrants and Non-Immigrants Suffering from Back Pain in Switzerland

OBJECTIVES

This study aimed at investigating the relationship between causal attributions and coping maxims in people suffering from back pain. Further, it aimed at identifying in how far causal attributions and related coping maxims would defer between immigrants and non-immigrants in Switzerland.

METHODS

Data for this study came from a larger survey study that was conducted among immigrant populations in the German- and Italian-speaking part of Switzerland. Included in the analyses were native Swiss participants, as well as Albanian- and Serbian-speaking immigrants, who had indicated to have suffered from back pain within the last 12 months prior to the study. Data was analyzed for overall 495 participants. Items for causal attributions and coping maxims were subject to factor analyses. Cultural differences were assessed with ANOVA and regression analyses. Interaction terms were included to investigate whether the relationship between causal attributions and coping maxims would differ with cultural affiliation.

RESULTS

For both immigrant groups the physician's influence on the course of their back pain was more important than for Swiss participants (p <.05). With regard to coping, both immigrant groups were more likely to agree with maxims that were related to the improvement of the back pain, as well as the acceptance of the current situation (p <.05). The only consistent interaction effect that was found indicated that being Albanian-speaking negatively moderated the relationship between physical activity as an attributed cause of back pain and all three identified coping maxims.

CONCLUSION

The study shows that differences in causal attribution and coping maxims between immigrants and non-immigrants exist. Further, the results support the assumption of an association between causal attribution and coping maxims. However cultural affiliation did not considerably moderate this relationship.

[Chronic pain : Perception, reward and neural processing]

Many chronic pain syndromes are characterized by enhanced perception of painful stimuli as well as alterations in cortical processing in sensory and motor regions. In this review article the alterations in muscle pain and neuropathic pain are described. Alterations in patients with fibromyalgia and chronic back pain are described as examples for musculoskeletal pain and also in patients with phantom limb pain after amputation and complex regional pain syndrome as examples for neuropathic pain. In addition to altered pain perception, cumulative evidence on alterations in the processing of reward and the underlying mechanisms in chronic pain has been described. A description is given of what is known on how pain and reward interact and affect each other. The relevance of such interactions for chronic pain is discussed. The implications of these findings for therapeutic approaches are delineated with respect to sensorimotor training and behavioral therapy, focusing on the effectiveness of these approaches, mechanisms and future developments. In particular, we discuss operant behavioral therapy in patients with chronic back pain and fibromyalgia as well as prosthesis training in patients with phantom limb pain and discrimination, mirror and imaginary training in patients with phantom limb pain and complex regional pain syndrome. With respect to the processing of reward, the focus of the discussion is on the role of reward and associated learning in pain therapy.

[Differential diagnostic considerations using ICD-10 in chronic back pain with special regard to persistent somatoform pain disorder with somatic and psychological factors (ICD-10 F45.41)]

It is often difficult to pass an expert opinion in cases of chronic back pain. This article analyses the differential diagnostic considerations related to coding various causes in line with ICD-10. It emphasises the I importance of making a careful distinction between orthopoedic and psychiatric conditions and disorders. Simultaneous coding of orthopoedic and psychiatric illnesses and disorders based on a distinct cluster of symptoms necessitates an interdisciplinary approach that consistently applies the ICD-10 definitions of mental an behavioural disorders in order to clearly identify the main reason for a functional impairment in the insurance and sociomedical context. Persistant somatoform pain disorder with somatic and psychological factors (ICD-10 F45.41) should be regarded as related to the underlying disease and be used primarily as an additional and descriptive diagnosis.

Demand, Control and Support at Work Among Sick-Listed Patients with Neck or Back Pain: A Prospective Study

Purpose The main aim of this study was to assess changes in perceived demand, control and support at work of neck and back pain patients over 1 year. We also hypothesised that perceived changes in demand, control and support at work were associated with clinical improvement, reduced fear-avoidance beliefs and successful return to work. Methods Four hundred and five sick-listed patients referred to secondary care with neck or back pain were originally included in an interventional study. Of these, two hundred and twenty-six patients reported perceived psychosocial work factors at both baseline and 1-year follow-up, and they were later included in this prospective study. Changes in demand, control and support dimensions were measured by a total of nine variables. Results At the group level, no significant differences were found among the measured subscales. At the individual level, the regression analyses showed that decreases in fear-avoidance beliefs about work were consistently related to decreases in demand and increases in control, whereas decreases in disability, anxiety and depression were related to increases in support subscales. Conclusions The perception of demand, control and support appear to be stable over 1 year in patients with neck and back pain, despite marked improvement in pain and disability. Disability, anxiety, depression and fear-avoidance beliefs about work were significantly associated with the perception of the work environment, whereas neck and back pain were not.

Relationships Between Weight, Physical Activity, and Back Pain in Young Adult Women

Back pain causes enormous financial and disability burden worldwide, which could potentially be reduced by understanding its determinants to develop effective prevention strategies. Our aim was to identify whether modifiable risk factors, weight and physical activity, are predictive of back pain in young adult women.Women born between 1973 and 1978 were randomly selected from the national health insurance scheme database to participate in The Australian Longitudinal Study of Women's Health. Self-reported data on back pain in the last 12 months, weight, height, age, education status, physical activity, and depression were collected in 2000, 2003, 2006, 2009, and 2012. In 2000, 9688 women completed the questionnaire and 83% completed follow-up 12 years later.At baseline, median age was 24.6 years and 41% had self-reported back pain. For every 5 kg higher weight at baseline, there was a 5% (95% confidence interval [CI] 4%-6%) increased risk of back pain over the next 12 years. Higher weight at each survey also predicted back pain risk 3 years later (P < 0.001). The effects of weight on back pain were most significant in those with BMI ≥25 kg/m and were observed at all levels of physical activity. Inadequate physical activity and depression were independent predictors of back pain over the following 12 years (both P < 0.001), after adjusting for age, weight, height, and education status.Back pain is common in community-based young adult women. Higher weight, inadequate levels of physical activity, and depression were all independent predictors of back pain over the following decade. Furthermore, the adverse effects of weight on back pain were not mitigated by physical activity. Our findings highlight the role of both higher weight and physical inactivity in back pain among young women and suggest potential opportunities for future prevention.
