Abstract
Purpose An increasing number of workers in the US have chronic health conditions that limit their ability to work, and few worksite interventions have been tested to improve worker coping and problem solving at work. The purpose of this study was to evaluate a worksite-based health self-management program designed to improve workplace function among workers with chronic health conditions. Methods We conducted a randomized, controlled trial of a worksite self-management program ("Manage at Work") (clinicaltrials.gov #NCT01978392) for workers with chronic health conditions (N = 119; 82% female, ages 20-69). Most workers were recruited from the health care or light manufacturing industry sectors. Workers attended a 5-session, facilitated psychoeducational program using concepts of health self-management, self-efficacy, ergonomics, and communication. Changes on outcomes of work engagement, work limitation, job satisfaction, work fatigue, work self-efficacy, days absent, and turnover intention at 6-month follow-up were compared to wait-list controls. Results The most prevalent chronic health conditions were musculoskeletal pain, headaches, vision problems, gastrointestinal disorders, respiratory disorders, and mental health disorders. The self-management program showed greater improvement in work engagement and turnover intent at 6-month follow-up, but there was no evidence of a parallel reduction in perceived work limitation. Trends for improved outcomes of work self-efficacy, job satisfaction, and work fatigue in the intervention group did not reach statistical significance in a group x time interaction test. Conclusions Offering a worksite self-management program to workers with chronic health conditions may be a feasible and beneficial strategy to engage and retain skilled workers who are risking disability.Clinical trial registration: Clinicaltrials.gov #NCT01978392.

Abstract
OBJECTIVES Investigate the presence of widespread pain in a well-defined TMD group and analyze its interrelationship with various comorbidities. Also, longitudinally seek the difference in treatment response according to the presence of widespread pain. SUBJECTS AND METHODS The observational study involved 45 female TMD patients in their 20s. Patients were grouped into localized and widespread pain groups based on the widespread pain index (WPI ≥ 4). Clinical characteristics and levels of comorbidities were analyzed through physical examination and validated questionnaires. Differences between the groups and the power of pre-treatment WPI in predicting pre-treatment comorbidities and post-treatment pain level improvement were statistically analyzed. RESULTS Patients with widespread pain showed higher somatization and anxiety levels. SF-36 scores were significantly lower and more patients complained of gastrointestinal symptoms. Conventional treatment significantly reduced pain intensity in both groups but less in the widespread pain group. WPI showed significant chances to predict patients showing improvement in pain levels with treatment with a cutoff value of 4. WPI was also effective in differentiating patients that showed a higher level of somatization. CONCLUSION Widespread pain index could be effectively applied in differentiating those with a higher level of psychological distress and predicting TMD treatment response with further investigations into its reliability.

Abstract
OBJECTIVES The goal of the present study was to explore additional evidence of validity of the Serbian version of the Central Sensitization Inventory (CSI), a patient-reported outcome measure of symptoms that have been found to be associated with central sensitization (CS). The CSI has been found to be psychometrically sound, and has demonstrated evidence of convergent and discriminant validity in numerous published studies and in multiple languages. METHODS CSI data were collected from 399 patients with chronic pain who had various diagnoses and from 146 pain-free controls. In addition, the patient sample completed a battery of validated patient-reported outcome measures of sleep problems, cognitive problems, pain catastrophizing, pain-related fear-avoidance, decreased quality of life, and decreased perception of social support. Six patient subgroups were formed, with presumably different levels of CS (including those with fibromyalgia, multiple pain sites, and localized pain sites). RESULTS Significant differences were found in total CSI scores among the controls and patient subgroups. Those with fibromyalgia and multiple pathologies scored highest and the control subjects scored lowest. Other patient-reported CS-related symptom dimensions were significantly correlated with total CSI scores. When the patients were divided into CSI severity subgroups (from subclinical to extreme), the severity of these other symptom dimensions increased with the severity of CSI scores. CONCLUSIONS The current study successfully demonstrated additional evidence of the convergent and discriminant validity of the Serbian version of the CSI.

Abstract
Chronic widespread pain (CWP) is one of the most difficult pain conditions to treat due to an unknown etiology and a lack of innovative treatment design and effectiveness. Based upon preliminary findings within the fields of motivational psychology, integrative neuroscience, diaphragmatic breathing, and vagal nerve stimulation, we propose a new treatment intervention, motivational non-directive (ND) resonance breathing, as a means of reducing pain and suffering in patients with CWP. Motivational ND resonance breathing provides patients with a noninvasive means of potentially modulating five psychophysiological mechanisms imperative for endogenously treating pain and increasing overall quality of life.

Use of the Central Sensitization Inventory (CSI) as a treatment outcome measure for patients with chronic spinal pain disorder in a functional restoration program. Spine J 2017; 17:1819-1829. [PMID: 28619687 DOI: 10.1016/j.spinee.2017.06.008] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Revised: 05/15/2017] [Accepted: 06/07/2017] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The Central Sensitization Inventory (CSI) is a valid and reliable patient-reported instrument designed to identify patients whose presenting symptoms may be related to central sensitization (CS). Part A of the CSI measures a full array of 25 somatic and emotional symptoms associated with CS, and Part B asks if patients have previously been diagnosed with one or more specific central sensitivity syndromes (CSSs) and related disorders. The CSI has previously been validated in a group of patients with chronic pain who were screened by a trained psychiatrist for specific CSS diagnoses. It is currently unknown if the CSI can be a useful treatment-outcome assessment tool for patients with chronic spinal pain disorder (CSPD) who are not screened for comorbid CSSs. It is known, however, that previous studies have identified CS-related symptoms, and comorbid CSSs, in subsets of patients with CSPDs. Studies have also shown that CS-related symptoms can be influenced by cognitive and psychosocial factors, including abuse history in both childhood and adulthood, sleep disturbance, catastrophic and fear-avoidant cognitions, and symptoms of depression and anxiety. PURPOSE This study aimed to evaluate CSI scores, and their associations with other clinically relevant psychosocial variables, in a cohort of patients with CSPD who entered and completed a functional restoration program. STUDY DESIGN/SETTING A retrospective study of prospectively collected data from a cohort study of patients with CSPD, who completed the CSI at admission to, and discharge from, an interdisciplinary function restoration program (FRP) was carried out. PATIENT SAMPLE A cohort of 763 patients with CSPD comprised the study sample. OUTCOME MEASURES Clinical interviews evaluated mood disorders and abuse history. A series of self-reported measures evaluated comorbid psychosocial symptoms, including pain intensity, pain-related anxiety, depressive symptoms, somatization symptoms, perceived disability, and sleep disturbance, at FRP admission and discharge. METHODS Patients were grouped into five severity level groups, from mild to extreme, based on total CSI scores, at FRP admission, and then again at discharge. The FRP included a quantitatively directed and medically supervised exercise process, as well as a multimodal psychosocial disability management component. RESULTS The CSI severity groups were strongly associated with Major Depressive Disorder and previous abuse history (p<.01), which are known risk factors for CS-related symptoms and diagnoses. The CSI scores were also strongly associated with patient-reported CSS diagnoses on CSI Part B. The percentage of patients who reported a comorbid CSS diagnosis increased in each higher CSI-severity group, from 11% in the Subclinical group, to 56% in the Extreme group. The CSI severity groups were significantly related to other CS-related patient-reported symptoms, including pain intensity, pain-related anxiety, depressive symptoms, somatization symptoms, perceived disability, and sleep disturbance (p's<.001). The CSI scores, along with all other psychosocial measures, decreased at treatment discharge. CONCLUSIONS In the present study, admission CSI scores were highly associated with previous CSS diagnoses, CS-related symptoms, and clinically relevant patient-reported psychosocial variables. All psychosocial variables, as well as scores on the CSI, were significantly improved at FRP discharge. The CSI may have important clinical utility, as a screener and as a treatment outcome measure, for patients with CSPD participating in an interdisciplinary FRP.

Abstract
OBJECTIVES To determine (1) whether there are differences in the prevalence of clinical hip symptoms between older adults with and without chronic low back pain (CLBP); and (2) whether coexisting hip symptoms are associated with worse physical performance and poorer health-related quality of life (HRQOL). DESIGN Case-control study. SETTING Individuals participated in a standardized evaluation in a clinical laboratory. PARTICIPANTS Clinical hip symptoms, which are proposed predictors of radiographic hip osteoarthritis according to American College of Rheumatology guidelines, were evaluated in a volunteer sample of community-dwelling older adults with CLBP (n=54; aged 60-85y) and in age- and sex-matched healthy controls (n=54). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Physical performance was measured by the repeated chair rise test and stair-climbing test. HRQOL was measured by the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). RESULTS Hip joint pain, morning stiffness, and pain with hip internal rotation were more common among older adults with CLBP (P<.05). Participants with CLBP and coexisting hip symptoms had worse physical performance than individuals without CLBP or hip symptoms (P<.0001). Additionally, the presence of coexisting hip symptoms was associated with worse HRQOL, particularly in the domains of social functioning, mental health, and role limitations attributable to emotional problems as measured by the SF-36 (P<.01). CONCLUSIONS Given our limited understanding of CLBP among older adults, there is a definitive need to systematically explore coexisting pain conditions that may contribute to worse outcomes. Based on these data, future longitudinal studies should explore whether coexisting hip symptoms are associated with a worse prognosis in older adults with CLBP.

Abstract
Background Clinical examination findings are used in primary care to give an initial diagnosis to patients with low back pain and related leg symptoms. The purpose of this study was to develop best evidence Clinical Diagnostic Rules (CDR] for the identification of the most common patho-anatomical disorders in the lumbar spine; i.e. intervertebral discs, sacroiliac joints, facet joints, bone, muscles, nerve roots, muscles, peripheral nerve tissue, and central nervous system sensitization. Methods A sensitive electronic search strategy using MEDLINE, EMBASE and CINAHL databases was combined with hand searching and citation tracking to identify eligible studies. Criteria for inclusion were: persons with low back pain with or without related leg symptoms, history or physical examination findings suitable for use in primary care, comparison with acceptable reference standards, and statistical reporting permitting calculation of diagnostic value. Quality assessments were made independently by two reviewers using the Quality Assessment of Diagnostic Accuracy Studies tool. Clinical examination findings that were investigated by at least two studies were included and results that met our predefined threshold of positive likelihood ratio ≥ 2 or negative likelihood ratio ≤ 0.5 were considered for the CDR. Results Sixty-four studies satisfied our eligible criteria. We were able to construct promising CDRs for symptomatic intervertebral disc, sacroiliac joint, spondylolisthesis, disc herniation with nerve root involvement, and spinal stenosis. Single clinical test appear not to be as useful as clusters of tests that are more closely in line with clinical decision making. Conclusions This is the first comprehensive systematic review of diagnostic accuracy studies that evaluate clinical examination findings for their ability to identify the most common patho-anatomical disorders in the lumbar spine. In some diagnostic categories we have sufficient evidence to recommend a CDR. In others, we have only preliminary evidence that needs testing in future studies. Most findings were tested in secondary or tertiary care. Thus, the accuracy of the findings in a primary care setting has yet to be confirmed.

Abstract
BACKGROUND Multi-morbidity in older adults is commonly associated with depressed mood. Similarly, subjective reports of pain are also associated with both physical illness and increased depressive symptoms. However, whether pain independently contributes to the experience of depression in older people with multi-morbidity has not been studied. METHODS In this study, participants were 1281 consecutive older adults presenting to one of 19 primary care services in Australia (recruitment rate = 75%). Participants were asked to indicate the presence of a number of common chronic illnesses, to rate their current pain severity and to complete the Geriatric Depression Scale. RESULTS Results confirmed that the number of medical illnesses reported was strongly associated with depressive symptoms. Twenty-six percent of participants with multi-morbidity scored in the clinical range for depressive symptoms in comparison to 15% of participants with no illnesses or a single illness. In regression analyses, the presence of chronic pain (t = 5.969, p < 0.0005), diabetes (t = 4.309, p < 0.0005), respiratory (t = 3.720, p < 0.0005) or neurological illness (t = 2.701, p = 0.007) were all independent contributors to depressive symptoms. Even when controlling for each individual illness, and the overall number of illnesses (t = 2.207, p = 0.028), pain severity remained an independent predictor of depressed mood (F change = 28.866, p < 0.0005, t = 5.373, p < 0.0005). CONCLUSIONS Physicians should consider screening for mood problems amongst those with multi-morbidity, particularly those who experience pain.

Abstract
Introduction Frequent chronic local pain can develop into chronic widespread pain (CWP). The spread of pain is correlated with pain intensity, anxiety, and depression, conditions that ultimately lead to a poor quality of life. Knowledge is incomplete about CWP’s etiology, although it has been suggested that both central hyperexcitability and/or a combination with peripheral factors may be involved. Cerebrospinal fluid (CSF) could act as a mirror for the central nervous system as proteins are signal substances that activate the formation of algesics and control nociceptive processes. To this end, this study investigates the CSF protein expression in women with CWP and in female healthy controls. Materials and methods This study included 12 female patients with CWP diagnosed according to the American College of Rheumatology criteria with 13 healthy age- and sex-matched pain-free subjects. All subjects went through a clinical examination and answered a health questionnaire that registered sociodemographic and anthropometric data, pain characteristics, psychological status, and quality of life rating. CSF was collected by lumbar puncture from each subject. Two-dimensional gel electrophoresis in combination with mass spectrometry was used to analyze the CSF proteome. This study identifies proteins that significantly discriminate between the two groups using multivariate data analysis (MVDA) (i.e., orthogonal partial least squares discriminant analysis [OPLS-DA]). Results There were no clinically significant levels of psychological distress and catastrophization presented in subjects with CWP. MVDA revealed a highly significant OPLS-DA model where 48 proteins from CSF explained 91% (R2) of the variation and with a prediction of 90% (Q2). The highest discriminating proteins were metabolic, transport, stress, and inflammatory. Conclusion The highest discriminating proteins (11 proteins), according to the literature, are involved in apoptotic regulations, anti-inflammatory and anti-oxidative processes, the immune system, and endogenous repair. The results of this explorative study may indicate the presence of neuro-inflammation in the central nervous system of CWP patients. Future studies should be larger and control for confounders and determine which alterations are unspecific/general and which are specific changes.

Abstract
This cross-sectional study investigates the plasma inflammatory profile of chronic widespread pain (CWP) patients compared to healthy controls (CON). Rather than analyzing a relatively few substances at a time, we used a new multiplex proximity extension assay (PEA) panel that enabled the simultaneous analysis of 92 inflammation-related proteins, mainly cytokines and chemokines.Seventeen women with CWP and 21 female CON participated and a venous blood sample was drawn from all subjects. Pain intensity and pain thresholds for pressure, heat, and cold were registered. A PEA panel (92 proteins) was used to analyze the blood samples. Multivariate data analysis by projection was used in the statistical analyses.Eleven proteins significantly differentiated the CON and CWP subjects (R = 0.58, Q = 0.37, analysis of variance of cross-validated predictive residuals P = 0.006). It was not possible to significantly regress pain thresholds within each group (CON or CWP). Positive significant correlations existed between several proteins and pain intensities in CWP, but the model reliability of the regression was poor.CWP was associated with systemic low-grade inflammation. Larger studies are needed to confirm the results and to investigate which alterations are condition-specific and which are common across chronic pain conditions. The presence of inflammation could promote the spreading of pain, a hallmark sign of CWP. As it has been suggested that prevalent comorbidities to pain (e.g., depression and anxiety, poor sleep, and tiredness) also are associated with inflammation, it will be important to determine whether inflammation may be a common mediator.

Abstract
OBJECTIVE Psychiatric comorbidities complicate treatment of patients with chronic pain and opioid use disorder, but the prevalence of specific comorbid psychiatric disorders in this population has not been systematically investigated. METHODS 170 consecutive participants entering a treatment research program for co-occurring chronic pain and opioid use disorder between March 2009 and July 2013 were evaluated with the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I/P) and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). RESULTS The prevalence of any lifetime (and current) comorbid Axis I disorder was 91% (75%); 52% met criteria for lifetime anxiety disorder (48% current), 57% for lifetime mood disorder (48% current), and 78% for lifetime nonopioid substance use disorder (34% current). Common current anxiety diagnoses were posttraumatic stress disorder (21%), generalized anxiety disorder (16%), and panic disorder without agoraphobia (16%). Common current mood diagnoses were major depressive disorder (40%) and dysthymia (11%). A majority of patients had a personality disorder (52%). CONCLUSIONS High rates and persistence of co-occurring psychiatric disorders, including anxiety or mood disorders, may explain in part the difficulty providers have treating patients with co-occurring opioid use disorder and chronic pain and suggest possible targets for improving treatment. TRIAL REGISTRATION ClinicalTrials.gov identifiers: buprenorphine/naloxone treatment (NCT00634803), opioid treatment program-based methadone maintenance treatment (NCT00727675).

BMC Musculoskelet Disord 2015; 16:165.

Abstract
BACKGROUND The clinical knowledge of factors related to the spread of pain on the body has increased and understanding these factors is essential for effective pain treatment. This population-based study examines local (LP), regional (RP), and widespread pain (WSP) on the body regarding comorbidities, pain aspects, and impact of pain and elucidates how the spread of pain varies over time. MATERIAL AND METHODS A postal questionnaire that addressed pain aspects (intensity, frequency, duration and anatomical spreading on a body manikin), comorbidities and implications of pain (i.e., work situation, physical activity, consumption of health care and experience of hospitality and treatment of health care) was sent to 9000 adults living in southeastern Sweden. Of these, 4774 (53 %) completed and returned the questionnaire. After 9 weeks, a follow-up questionnaire was sent to the 2983 participants who reported pain in the first questionnaire (i.e. 62 % of 4774 subjects). Of these, 1940 completed and returned the questionnaire (i.e. 65 % of 2983 subjects). The follow-up questionnaire included the same items as the first questionnaire. RESULTS This study found differences in intensity, frequency and duration of pain, comorbidities, aspects of daily functioning and health care seeking in three pain categories based on spreading of pain: LP, RP and WSP. Compared to the participants with RP and LP, the participants with WSP had lower education and worse overall health, including more frequent heart disease and hypertension. In addition, participants with WSP had more intense, frequent, and long-standing pain, required more medical consultations, and experienced more impact on work. The participants with RP constituted an intermediate group regarding frequency and intensity of pain, and impact on work. The participants with LP were the least affected group regarding these factors. A substantial transition to RP had occurred by the 9-week follow-up. CONCLUSIONS This study shows an association between increased spread of pain and prevalence of heart disease, hypertension, more severe pain characteristics (i.e., intensity, frequency and duration), problems with common daily activities and increased health care seeking. The WSP group was the most affected group and the LP group was the least affected group. Regarding these factors, RP was an obvious intermediate group. The transitions between the pain categories warrant research that broadly investigates factors that increase and decrease pain.

Abstract
Pain is the most common reason why patients see a physician. Within the USA, it has been estimated that at least 116 million US adults suffer from chronic pain, with an estimated annual national economic cost of $560-635 billion. While pain is in part a sensory process, like sight, touch, or smell, pain is also in part an emotional experience, like depression, anxiety, or anger. Thus, chronic pain is arguably the quintessential biopsychosocial condition. Due to the overwhelming evidence of the biopsychosocial nature of pain and the value of psychological assessments, the majority of chronic pain guidelines recommend a psychological evaluation as an integral part of the diagnostic workup. One biopsychosocial inventory designed for the assessment of patients with chronic pain is the Battery for Health Improvement 2 (BHI 2). The BHI 2 is a standardized psychometric measure, with three validity measures, 16 clinical scales, and a multidimensional assessment of pain. This article will review how the BHI 2 was developed, BHI 2 concepts, validation research, and an overview of the description and interpretation of its scales. Like all measures, the BHI 2 has strengths and weaknesses of which the forensic psychologist should be aware, and particular purposes for which it is best suited. Guided by that knowledge, the BHI 2 can play a useful role in the forensic psychologist's toolbox.

Abstract
STUDY DESIGN A retrospective study of prospectively collected data. OBJECTIVE To determine whether comorbid fibromyalgia, identified in patients with chronic disabling occupational musculoskeletal disorders (CDOMDs), resolves with a functional restoration program (FRP). SUMMARY OF BACKGROUND DATA Fibromyalgia involves widespread bodily pain and tenderness to palpation. In recent studies, 23% to 41% of patients with CDOMDs entering an FRP had comorbid fibromyalgia, compared with population averages of 2% to 5%. Few studies have examined whether fibromyalgia diagnoses resolve with any treatment, and none have investigated diagnosis responsiveness to an FRP. METHODS A consecutive cohort of patients with CDOMDs (82% with spinal disorders and all reporting chronic spinal pain) and comorbid fibromyalgia (N = 117) completed an FRP, which included quantitatively directed exercise progression and multimodal disability management. Diagnosis responsiveness, evaluated at discharge, created 2 groups: those who retained fibromyalgia and those who did not. These groups were compared with chronic regional lumbar pain only patients (LO group, n = 87), lacking widespread pain and fibromyalgia. RESULTS Of the patients with comorbid fibromyalgia, 59% (n = 69) retained the fibromyalgia diagnosis (RFM group) and 41% (n = 48) lost the fibromyalgia diagnosis (LFM group) at discharge. Although all 3 groups reported decreased pain intensity, disability, and depressive symptoms from admission to discharge, RFM patients reported higher symptom levels than the LFM and LO groups at discharge. The LFM and LO groups were statistically similar. At 1-year follow-up, LO patients demonstrated higher work retention than both fibromyalgia groups (P < 0.03). CONCLUSION Despite a significant comorbid fibromyalgia prevalence in a cohort of patients with CDOMDs entering an FRP, 41% of patients with an initial fibromyalgia diagnosis no longer met diagnostic criteria for fibromyalgia at discharge and were indistinguishable from LO patients on pain, disability, and depression symptoms. However, both fibromyalgia groups (LFM and RFM) had lower work retention than LO patients 1 year later, suggesting that an FRP may suppress symptoms of fibromyalgia in a subset of patients, but prolonged fibromyalgia-related disability may be more difficult to overcome. LEVEL OF EVIDENCE 2.

Abstract
Background The prevalence of chronic non-malignant pain in developed countries is high, ranging from 14% to 50%. Patients with chronic pain are active users of health-care services and they report impaired health-related quality of life (HRQoL) when compared with the general population. Psychological distress has been identified as one of the risk factors for pain chronicity. Depression, anxiety and negative beliefs are associated with pain interference and perceived disability. Multidisciplinary pain management (MPM) aims to rehabilitating chronic pain patients by addressing both physical, psychological, social and occupational factors related to the pain problem. MPM programmes have been shown to be effective in reducing pain and improving function in patients with diverse chronic pain states. However, MPM programmes are often heterogeneous and predicting MPM treatment results in different patients groups may be difficult. Methods The present study examined changes in HRQoL after MPM in 439 patients treated at a multidisciplinary pain clinic using the 15D HRQoL questionnaire. The characteristics of the 100 patients with the greatest improvement and the 100 patients with the largest decrease in HRQoL were examined more closely (demographics, characteristics of pain, pain interference, psychiatric comorbidity, employment status, details of MPM) after answering a follow-up 15D questionnaire at three years after their MPM had ended. Result During MPM, HRQoL was significantly improved in 45.6% of the 439 patients, decreased in 30.7% of the patients and did not change in 23.7% of the patients. Patient-related factors that predicted a better HRQoL among the 100 patients with good MPM outcome compared with the 100 patients with poor MPM outcome were higher education and better employment status. Age, gender, marital status, duration of pain, number of pain sites, pain intensity or pain interference at baseline did not differ between the patient groups. Patient expectations regarding MPM were similar. A tendency towards more psychiatric comorbidity in the non-responder group was seen. The duration of MPM in the two patient groups was similar, as well as the number of medications started, the variety of specialists seen and psychiatric counselling with supportive therapy included. More non-responder than responder patients had died during the three-year follow-up period, some of the deaths were related to substance abuse. Conclusions and Implications HRQoL in chronic pain patients was significantly improved during MPM compared with the baseline. Pain duration of several years, multiple pain sites and neuropathic pain were not discerning factors between the responders and non-responders of the present study, implying that a positive change in HRQoL may be achieved by MPM even in these pain patients. In agreement with previous studies, factors predicting poor treatment outcome in the non-responder group of chronic pain patients were not treatment related. To further improve MPM outcome even in pain patients with risk factors for less benefit of treatment such as low education and poor general health, more individualized MPM approaches with emphasis on analysis and treatment of psychological symptoms and patient beliefs is essential.

Abstract
Objective: The aim was to describe the differences in symptoms, functioning and quality of life between women on long-term sick-leave due to protracted musculoskeletal pain with and without concomitant depression. Design: Descriptive and comparisons with/without comorbid depression. Methods: 332 female patients were examined by three specialist physicians in psychiatry, orthopedic surgery, and rehabilitation medicine and assigned to four groups according to the ICD-10 diagnoses: low back/joint disorders (LBJ, n = 150), myalgia (M, n = 43), fibromyalgia (FM, n = 87), or depression without somatic pain diagnosis (DE, n = 52). Results: Patients with somatic pain conditions LBJ, M, or FM showed more activity-related difficulties if concomitant depression was present during the activities ‘focusing attention’, ‘making decisions’, and ‘undertaking a single task’; and in the domains ‘energy level’, ‘memory functions’, ‘emotional functions’, and ‘optimism/pessimism’. Patients with FM and concomitant depression perceived higher pain intensity than patients in group DE. No statistically significant differences in physically related activities were noted between each of the somatic pain conditions with and without coexisting depression. FM patients with coexisting depression reported fewer painful sites on their pain drawings compared with FM-patients without depression. Patients with LBJ or FM and concomitant depression reported lower quality of life in the dimensions vitality, social functioning, emotional role, and mental health. Comorbid depression affected disability and restricted working capacity by reducing mental activity and functioning but not by affecting physical activity problems. Conclusion: Women on long-term sick-leave, who have concomitant depression with LBJ or FM, also have more difficulties in focusing attention, making decisions, and carrying out tasks, and with memory functions and optimism/pessimism, as well as reduced quality of life in the dimensions of vitality, social functioning, emotional role, and mental health, than female patients without comorbid depression. As a consequence we suggest further efforts to integrate somatic and psychiatric interventions in the same rehabilitation program.

Abstract
BACKGROUND The Pain Anxiety Symptoms Scale (PASS) was developed to measure fear and anxiety responses to pain. Many studies have found associations between PASS scores and self-report measures of pain, anxiety, and disability as well as among inhibited movement patterns and activity avoidance behaviors (eg, kinesophobia). This study aimed to identify clinically meaningful cut-off points to identify high or low levels of pain anxiety and to determine if the PASS provides additional useful information in a functional restoration (FR) treatment program for chronic disabling occupational musculoskeletal disorder (CDOMD) patients. METHODS A consecutive cohort of 551 patients with CDOMD, who entered and completed a FR program, was administered a battery of psychosocial assessments, including the PASS, at admission and discharge. Socioeconomic outcomes were collected 1 year after discharge. After identifying clinical ranges for mild, moderate, and severe pain anxiety, the three groups were compared on self-report measures of psychosocial distress, clinical diagnoses of psychosocial disorders, and 1-year socioeconomic outcomes. RESULTS Correlations between the PASS and all measures of pain, anxiety, and disability were statistically significant. However, only the Pain Disability Questionnaire showed a large correlation coefficient (r > 0.5). Patients with the highest PASS scores were more likely to be diagnosed with a number of Axis I (depression, opioid dependence) or Axis II (Borderline Personality) psychiatric disorders. They were more likely to display treatment-seeking behavior at 1 year after discharge. However, the PASS failed to differentiate between any other 1-year outcomes. CONCLUSIONS The PASS is elevated when other measures of psychosocial distress are also elevated. However, the PASS fails to discriminate between different indices of depression and anxiety and it is not highly related to 1-year outcomes in a CDOMD cohort. If time and resources are limited, a different measure of psychosocial distress that does relate to socioeconomic outcomes might be a better option in a CDOMD evaluation process.

Abstract
OBJECTIVE Evaluating the efficacy of an intensive, dynamic and multidisciplinary spine-specific functional restoration program in patients with chronic low back pain with or without surgery. METHODS One hundred and forty-four subjects with chronic low back pain included in the retrospective study and divided into two groups: patients who had spine surgery (GI, n=81) and patients who did not have surgery (GC, n=37). The two groups followed the same functional restoration program (175 hours). All the subjects were evaluated before (T0) and after (T5wks) rehabilitation care based on physical, functional, psychological and professional parameters. RESULTS All outcome measures were significantly improved for all subjects at the end of the study, regardless of the group. Eighty-one percent of patients returned to work. The surgery group obtained better results at the end of the program for pain and back muscle isometric endurance measures. CONCLUSIONS The effects of the intensive program were validated; nevertheless, spine surgery seems to have a positive impact on some physical parameters of this spine-specific functional restoration program.

Abstract
The aim of this study was to review emerging data from the fields of nursing, rheumatology, dentistry, gastroenterology, gynecology, neurology, and orthopedics that support or dispute pathophysiologic similarities in pain syndromes studied by each specialty. A literature search was performed through PubMed and Ovid using the terms fibromyalgia, temporomandibular joint disorder, irritable bowel syndrome, irritable bladder/interstitial cystitis, headache, chronic low back pain, chronic neck pain, functional syndromes, and somatization. Each term was linked with pathophysiology and/or central sensitization. This paper presents a review of relevant articles with a specific goal of identifying pathophysiologic findings related to nociceptive processing. The extant literature presents considerable overlap in the pathophysiology of these diagnoses. Given the psychosomatic lens through which many of these disorders are viewed, demonstration of evidence-based links supporting shared pathophysiology between these disorders could provide direction to clinicians and researchers working to treat these diagnoses. "Central sensitivity syndromes" denotes an emerging nomenclature that could be embraced by researchers investigating each of these disorders. Moreover, a shared paradigm would be useful in promoting cross-fertilization between researchers. Scientists and clinicians could most effectively forward the understanding and treatment of fibromyalgia and other common chronic pain disorders through an appreciation of their shared pathophysiology.
