Full Text Available The improved management of pain among the growing number of female Veterans receiving care through the Veterans Health Administration has been established as a priority, but studies suggest that females may respond differently to pain treatment. This study explored differences between female and male Veterans engaged in a Chronic Pain Rehabilitation Program and determined how female and male Veterans change following participation. Veterans (N = 324 in a 3 wk inpatient program completed self-report measures at admission, discharge, and 3 mo follow-up. Participants were 21% female (n = 67 and 79% male (n = 257. Compared with males, females were younger and less likely to be white or married/partnered. Females reported shorter pain duration and were more likely to have primary head or limb pain. At admission, fewer females were prescribed opioids than males and at lower doses. After opioid cessation in the program, however, there were no significant differences in use between the sexes at follow-up. Improvements in a range of domains were sustained at follow-up for both sexes, but females did not maintain gains in pain intensity or sleep while males reported more pain-related fear at discharge and follow-up. This study adds to the literature on sex-specific variations in chronic pain and implications for treatment.

Chronic pain and depression are coexisting entities with high simultaneous prevalence. Both are linked with early adversities. Early maladaptive schemas (EMS) can be seen as a reflection of these adversities. EMSs extensively indicate underlying psychic patterns and provide a good opportunity to detect covert processes and psychic shapes (latent factors), which create the basis of how people rate their schemas. The purpose of this study was to explore these latent, higher order schema factors (SF) and to find out how they are associated with pain intensity or depression in chronic pain patients and a control sample. The study subjects consisted of 271 first-visit pain patients and 331 control participants. Sociodemographic and pain data were gathered by questionnaire; 18 EMSs were measured with the Young Schema Questionnaire (short form) and depressiveness was measured with the Beck Depression Inventory, Version II. Exploratory factor and regression analyses were used. The chronic pain patient group showed two SFs. The first SF showed a shameful, defective, socially isolated, failure, emotionally inhibited, deprived, submissive and resigned pattern. The second SF showed a demanding, approval seeking, self-sacrificing and punitive pattern. SF1 predicted more than half of the depressiveness in the pain patient sample. A three-factor structure was found in the control sample, and SFs 1 and 3 together predicted almost one-third of depressiveness. The pain patient and the control groups had a different, higher order factor structure. We assume that SF1 in the pain patients reflected a rather serious, undefined early psychic trauma and was also associated with their depressiveness. PMID:21210495

Full Text Available Abstract Background Low back pain (LBP is one of the leading causes of disability and has a major socioeconomic impact. Despite a large amount of research in the field, there remains uncertainty about the best treatment approach for chronic LBP, and identification of relevant patient subgroups is an important goal. Exercise therapy is a commonly used strategy to treat chronic low back pain and is one of several interventions that evidence suggests is moderately effective. In parallel with an update of the 2005 Cochrane review, we will undertake an individual participant data (IPD meta-analysis, which will allow us to standardize analyses across studies and directly derive results, and to examine differential treatment effects across individuals to estimate how patients’ characteristics modify treatment benefit. Methods/design We will use standard systematic review methods advocated by the Cochrane Collaboration to identify relevant trials. We will include trials evaluating exercise therapy compared to any or no other interventions in adult non-specific chronic LBP. Our primary outcomes of interest include pain, functional status, and return-to-work/absenteeism. We will assess potential risk of bias for each study meeting selection criteria, using criteria and methods recommended by the Cochrane BRG. The original individual participant data will be requested from the authors of selected trials having moderate to low risk of bias. We will test original data and compile a master dataset with information about each trial mapped on a pre-specified framework, including reported characteristics of the study sample, exercise therapy characteristics, individual patient characteristics at baseline and all follow-up periods, subgroup and treatment effect modifiers investigated. Our analyses will include descriptive, study-level meta-analysis and meta-regression analyses of the overall treatment effect, and individual-level IPD meta-analyses of treatment

Chronic pain places a significant burden on individuals as well as health services. Long wait lists to access public clinical pain management services can result, and health outcomes deteriorate. Innovative technologies, such as social media provide opportunities to support self-management within the participatory health framework. This paper aims to investigate patients' perceptions towards using social media while waiting for clinic access, with a particular focus on therapeutic affordances. Seventeen wait-listed patients underwent intervention using various social media resources as part of self-management. Thematic content analysis of semi-structured interviews examined patients' perceptions about social media use and participation. Three therapeutic affordances were most evident in the qualitative data: exploration, connection and narration. Barriers to participation were also identified, such as 'specificity of the resources'. Findings suggest social media are perceived positively. However, there is also the need to balance a desire to deliver evidence-based practice with patient-preferences in shared-decision making about social media use. PMID:27332267

We studied the associations of widespread pain with other pain and functional measures among patients with chronic epicondylitis. A total of 190 patients (66% females) participated in the study; with a mean age 43.7, mean duration of symptoms 48weeks, chronic lateral (n=160) and medial (n=30) epicondylitis. We analysed clinical status, grip strength and cubital pain thresholds and interviewed pain and disability, leisure time physical activity, strenuous hobby activities for arms, duration of symptoms, other systemic and upper extremity disorders, arm operations, and work ability. The location of pain was analysed using a whole-body pain drawing, categorized into three groups; the highest of which was classified as widespread pain. A total of 85 patients (45%) reported widespread pain. It was highly associated with female gender, high pain scores, decreased grip strength and pain thresholds (p<0.001 for all), with increased number of positive manual tests, low level of hobby strain for arms and physical activity, long duration of symptoms, and sick leave (p for all <0.05). It was also related to upper extremity disorders and arm surgery, but not with operated epicondylitis, other systemic diseases, workload or work ability. In addition, 39% of patients without other disease reported widespread pain. Widespread pain is common in chronic epicondylitis with and without other diseases, and is related to high pain scores, decreased function of the arm, long duration of symptoms, sick leave, and with a low level of physical activity.

This study aimed to investigate the effects of a two-day forest therapy program on individuals with chronic widespread pain. Sixty one employees of a public organization providing building and facilities management services within the Seoul Metropolitan area participated in the study. Participants were assigned to an experimental group (n = 33) who participated in a forest therapy program or a control group (n = 28) on a non-random basis. Pre- and post-measures of heart rate variability (HRV), Natural Killer cell (NK cell) activity, self-reported pain using the visual analog scale (VAS), depression level using the Beck Depression Inventory (BDI), and health-related quality of life measures using the EuroQol Visual Analog Scale (EQ-VAS) were collected in both groups. The results showed that participants in the forest therapy group, as compared to the control group, showed physiological improvement as indicated by a significant increase in some measures of HRV and an increase in immune competence as indicated by NK cell activity. Participants in the forest therapy group also reported significant decreases in pain and depression, and a significant improvement in health-related quality of life. These results support the hypothesis that forest therapy is an effective intervention to relieve pain and associated psychological and physiological symptoms in individuals with chronic widespread pain.

Brain-derived neurotrophic factor (BDNF) is a neurotrophin (NT) known to participate in chronic somatic pain. A recent study has indicated that BDNF may participate in chronic cystitis at the peripheral level. However, the principal site of action for this NT is the central nervous system, most notably the spinal cord. The effects of centrally-acting BDNF on bladder function in normal animals and its central role during chronic cystitis are presently unknown. The present study was undertaken to clarify this issue. For that purpose, control non-inflamed animals were intrathecally injected with BDNF, after which bladder function was evaluated. This treatment caused short-lasting bladder hyperactivity; whereas chronic intrathecal administration of BDNF did not elicit this effect. Cutaneous sensitivity was assessed by mechanical allodynia as an internal control of BDNF action. To ascertain the role of BDNF in bladder inflammation, animals with cyclophosphamide-induced cystitis received intrathecal injections of either a general Trk receptor antagonist or a BDNF scavenger. Blockade of Trk receptors or BDNF sequestration notably improved bladder function. In addition, these treatments also reduced referred pain, typically observed in rats with chronic cystitis. Reduction of referred pain was accompanied by a decrease in the spinal levels of extracellular signal-regulated kinase (ERK) phosphorylation, a marker of increased sensory barrage in the lumbosacral spinal cord, and spinal BDNF expression. Results obtained here indicate that BDNF, acting at the spinal cord level, contributes to bladder hyperactivity and referred pain, important hallmarks of chronic cystitis. In addition, these data also support the development of BDNF modulators as putative therapeutic options for the treatment of chronic bladder inflammation. PMID:23313710

Melatonin is a neurohormone secreted by epiphysis and extrapineal structures. It performs several functions including chronobiotic, antioxidant, oncostatic, immune modulating, normothermal, and anxiolytic functions. Melatonin affects the cardiovascular system and gastrointestinal tract, participates in reproduction and metabolism, and body mass regulation. Moreover, recent studies have demonstrated melatonin efficacy in relation to pain syndromes. The present paper reviews the studies on melatonin use in fibromyalgia, headaches, irritable bowel syndrome, chronic back pain, and rheumatoid arthritis. The paper discusses the possible mechanisms of melatonin analgesic properties. On one hand, circadian rhythms normalization results in sleep improvement, which is inevitably disordered in chronic pain syndromes, and activation of melatonin adaptive capabilities. On the other hand, there is evidence of melatonin-independent analgesic effect involving melatonin receptors and several neurotransmitter systems. PMID:26984272

Pain is frequent in communicative or no-communicative, ambulatory, institutionalized or hospitalized veterans. It is associated with severe comorbidity so much more than chronic pain could be neglected and expressed of atypical manner or masked by the absence of classical symptoms in particular in case of dementia or of sensory disorders. Pain detection by clinic examination or by pain assessment's methods and adequate approach by pharmacological and non pharmacological therapies are essential for correct pain management. On pharmacological plan, the strategy of the O.M.S. landings is applicable owing to a more particular attention to secondary effects and drugs interactions. AINS must be manipulated with prudence. There are no reasons to exclude opioides from the therapeutic arsenal but with a reduction of the starting doses, a regular adaptation and a very attentive survey. In drugs of landing 2, tramadol reveals itself as efficient and better tolerated as the codeine and dextropropoxyphene has to be to avoid. The obtaining of a satisfactory result depends on a regular assessment of the pain in a context of polydisciplinar approach (physicians, nurses, paramedicals, other care givers).
Clinical symptoms of chronic widespread pain (CWP) conditions including fibromyalgia (FM), include pain, stiffness, subjective weakness, and muscle fatigue. Muscle pain in CWP is usually described as fluctuating and often associated with local or generalized tenderness (hyperalgesia and/or allodynia). This tenderness related to muscle pain depends on increased peripheral and/or central nervous system responsiveness to peripheral stimuli which can be either noxious (hyperalgesia) or non-noxiou...

Chronic musculoskeletal pain results from a complex interplay of mechanical, biochemical, psychological, and social factors. Effective management is markedly different from that of acute musculoskeletal pain. Understanding the physiology of pain transmission, modulation, and perception is crucial for effective management. Pharmacologic and nonpharmacologic therapies such as psychotherapy and biofeedback exercises can be used to manage chronic pain. Evidence-based treatment recommendations have been made for chronic pain conditions frequently encountered by orthopaedic surgeons, including low back, osteoarthritic, posttraumatic, and neuropathic pain. Extended-release tramadol; select tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants; and topical medications such as lidocaine, diclofenac, and capsaicin are among the most effective treatments. However, drug efficacy varies significantly by indication. Orthopaedic surgeons should be familiar with the widely available safe and effective nonnarcotic options for chronic musculoskeletal pain.

Five women suffering from chronic pain comprised the purposive sample. They had completed an 8-week group pain-management program with two follow-ups, and thereafter continued as a self-help group. A narrative approach was used to analyze the written and image narratives guided by three analytic steps.Results: Findings showed that experiences of grief over time were commonly associated with chronic pain. The participants' past experiences reflected their grief at having to abandon jobs and social networks, and revealed loneliness and despair. The present life situation seemed to reflect adaptation, and hope for the future had been established. Overall, forward progression means an ongoing struggle towards a reintegrated body and a meaningful life.Conclusion: Through such narratives, health-care workers can identify treatment adherence related to grief and pain, and learn how people might regain their lives beyond using traditional interviews.Keywords: chronic pain, follow-up, grief, image, narrative, nursing

Central pain following traumatic brain injury (TBI) has not been studied in depth. Our purpose was to conduct a systematic study of patients with TBI suffering from chronic central pain, and to describe the characteristics of the central pain. Groups were TBI patients with (TBIP) and without central pain (TBINP) and healthy controls. TBI patients with other pain mechanisms were excluded from the study. Participants underwent quantitative somatosensory testing in the painful and pain-free body regions. Thresholds for warmth, cold, heat-pain, touch and graphesthesia were measured and pathologically evoked pain (allodynia, hyperpathia and wind-up pain) evaluated. Chronic pain was mapped and characterized. Chronic pain developed at a relatively late onset (6.6+/-9 months) was almost exclusively unilateral and reported as pricking, throbbing and burning. Although both TBIP and TBINP exhibited a significant reduction in thermal and tactile sensations compared to controls, thermal sensations in the painful regions of TBIP were significantly more impaired than pain-free regions in the same patients (p<0.01) and in TBINP (p<0.01). Painful regions also exhibited very high rates of allodynia, hyperpathia and exaggerated wind-up. The characteristics of the chronic pain resembled those of other central pain patients although TBIP displayed several unique features. The sensory profile indicated that damage to the pain and temperature systems is a necessary but not sufficient condition for the development of chronic central pain following TBI. Neuronal hyperexcitability may be a contributing factor to the chronic pain.

Chronic pain is defined as an unpleasant sensory and emotional experience persisting longer than the normal process of healing, usually longer than 3 months. About a fifth of the world's population is believed to suffer from chronic pain. In Europe, chronic pain accounts for nearly 500 m lost working days, and it costs the European economy >€34 billion (£28 billion) every year. Establishing a reliable diagnosis is the primary challenge in evaluating a patient with chronic pain. Common diagnoses not to miss include seronegative spondyloarthritides, endocrine abnormalities including severe vitamin D deficiency and polymyalgia rheumatica. Once important or treatable diagnoses have been ruled out, the history can be used as a tool to establish a therapeutic plan for shared decision-making using the biopsychosocial model. Onward referral to pain clinics can be helpful for more involved patient management, but often good outcomes are achieved with the support of primary care. PMID:26096090

Neurosurgical treatment of pain used two kind of techniques: 1) Lesional techniques interrupt the transmission of nociceptive neural input by lesionning the nociceptive pathways (drezotomy, cordotomy, tractotomy…). They are indicated to treat morphine-resistant cancer pain and few cases of selected neuropathic pain. 2) Neuromodulation techniques try to decrease pain by reinforcing inhibitory and/or to limit activatory mechanisms. Chronic electrical stimulation of the nervous system (peripheral nerve stimulation, spinal cord stimulation, motor cortex stimulation…) is used to treat chronic neuropathic pain. Intrathecal infusion of analgesics (morphine, ziconotide…), using implantable pumps, allows to increase their efficacy and to reduce their side effects. These techniques can improve, sometimes dramatically, selected patients with severe and chronic pain, refractory to all other treatments. The quality of the analgesic outcome depends on the relevance of the indications. PMID:25681114

Full Text Available Chronic pain is a debilitating condition with major socioeconomic impact, whose neurobiological basis is still not clear. An involvement of the neurovascular unit (NVU has been recently proposed. In particular, the blood-brain barrier (BBB and blood-spinal cord barrier (BSCB, two NVU key players, may be affected during the development of chronic pain; in particular, transient permeabilization of the barrier is suggested by several inflammatory- and nerve-injury-based pain models, and we argue that the clarification of molecular BBB/BSCB permeabilization events will shed new light in understanding chronic pain mechanisms. Possible biases in experiments supporting this theory and its translational potentials are discussed. Moving beyond an exclusive focus on the role of the endothelium, we propose that our understanding of the mechanisms subserving chronic pain will benefit from the extension of research efforts to the NVU as a whole. In this view, the available evidence on the interaction between analgesic drugs and the NVU is here reviewed. Chronic pain comorbidities, such as neuroinflammatory and neurodegenerative diseases, are also discussed in view of NVU changes, together with innovative pharmacological solutions targeting NVU components in chronic pain treatment.

Nonpharmacologic therapies have become a vital part of managing chronic pain (CP). Although these can be used as stand-alone therapies, nonpharmacologic treatments often are used to augment and complement pharmacologic treatments (ie, multimodal therapy). Nonpharmacologic approaches can be classified as behavioral, cognitive, integrative, and physical therapies. Core principles in developing a treatment plan are explaining the nature of the CP condition, setting appropriate goals, and developing a comprehensive treatment approach and plan for adherence. Clinicians should become familiar with these interventions so that they can offer patients flexibility in the pain management approach. Effective noninvasive treatment modalities for CP include behavioral therapy for short-term pain relief; cognitive behavioral therapy for reducing long-term pain and disability; hypnosis as adjunctive therapy; guided imagery, diaphragmatic breathing, and muscle relaxation, especially for cancer-related pain; mindfulness-based stress reduction for patients with chronic low back pain; acupuncture for multiple pain conditions; combination manipulation, manual therapy, endurance exercise, stretching, and strengthening for chronic neck pain; animal-assisted therapy; and S-adenosyl-L-methionine for joint pain. Guidelines for use of these treatment modalities are based on expert panel recommendations in combination with data from randomized controlled trials. PMID:25970869

Chronic pain is a pervasive and expensive public health problem affecting roughly one-third of the American population. The inability of language to accurately convey pain expressions combined with the social stigmas associated with discussing pain persuade many sufferers to remain silent about their pain. Gender politics and fear of professional repercussions further encourage silence. This article explores the need for a safe and secure place for chronic pain sufferers to talk of their pain experiences. The extent to which digital communication technology can fulfill this need is examined. This descriptive study examines the use of one online chronic pain management workshop for its ability to create an engaged community of choice. Workshop admittance was based on participants having a qualifying chronic pain condition. A thematic discourse analysis is conducted of all entries chronic pain participants posted. In addition to goal setting, participants discuss the ways in which pain affects them on a daily basis. Two themes emerge: validation and encouragement. This study suggests that chronic pain users need a discursive space to legitimate their chronic pain identity. It confirms that online websites and virtual audiences facilitate disclosure and allow for authentic communication. The benefits of computer-mediated discussion as well as its limitations are examined. PMID:23276258

Full Text Available Risky decision-making seems to be markedly disrupted in patients with chronic pain, probably due to the high cost that impose pain and negative mood on executive control functions. Patients’ behavioral performance on decision-making tasks such as the Iowa Gambling Task (IGT is characterized by selecting cards more frequently from disadvantageous than from advantageous decks, and by switching often between competing responses in comparison with healthy controls. In the present study, we developed a simple heuristic model to simulate individuals’ choice behavior by varying the level of decision randomness and the importance given to gains and losses. The findings revealed that the model was able to differentiate the behavioral performance of patients with chronic pain and healthy controls at the group, as well as at the individual level. The best fit of the model in patients with chronic pain was yielded when decisions were not based on previous choices and when gains were considered more relevant than losses. By contrast, the best account of the available data in healthy controls was obtained when decisions were based on previous experiences and losses loomed larger than gains. In conclusion, our model seems to provide useful information to measure each individual participant extensively, and to deal with the data on a participant-by-participant basis.

Chronic pain is pathological, persisting beyond normal tissue healing time. Previous work has suggested ∼50% variation in chronic pain development is heritable. No data are currently available on the heritability of pain categorized using the Chronic Pain Grade (CPG). Furthermore, few existing studies have accounted for potential confounders that may themselves be under genetic control or indeed 'heritable' non-genetic traits. This study aimed to determine the relative contributions of genetic, measured and shared environmental and lifestyle factors to chronic pain. Chronic pain status was determined and CPG measured in participants from Generation Scotland: the Scottish Family Health Study, a large cohort of well-characterized, extended families from throughout Scotland, UK. Heritability estimates (h (2) ) for 'any chronic pain' and 'severe' chronic pain (CPG 3 or 4) were generated using SOLAR software, with and without adjustment for shared household effects and measured covariates age, body mass index, gender, household income, occupation and physical activity. Data were available for 7644 individuals in 2195 extended families. Without adjustment, h (2) for 'any chronic pain' was 29% [standard errors (SE) 6%; p study supports the use of chronic pain as a phenotype in genetic studies, with adequate correction for confounders to specifically identify genetic risk factors for chronic pain.

Abdominal pain is a major clinical problem in patients with chronic pancreatitis.The cause of pain is usually multifactorial with a complex interplay of factors contributing to a varying degree to the pain in an individual patient and,therefore,a rigid standardized approach for pain control tends to lead to suboptimal results.Pain management usually proceeds in a stepwise approach beginning with general lifestyle recommendations,low fat diet,alcohol and smoking cessation are encouraged.Analgesics alone are needed in almost all patients.Maneuvers aimed at suppression of pancreatic secretion are routinely tried.Patients with ongoing symptoms may be candidates for more invasive options such as endoscopic therapy,and resective or drainage surgery.The role of pain modifying agents (antidepressants,gabapentin,peregabalin),celiac plexus block,antioxidants,octreotide and total pancreatectomy with islet cell auto transplantation remains to be determined.

This manuscript, developed by a group of chronic pain researchers and clinicians from around the world, aims to address the state of knowledge about fibromyalgia (FM) and identify ongoing challenges in the field of FM and other chronic pain syndromes that may be characterized by pain centralization/amplification/hypersensitivity. There have been many exciting developments in research studies of the pathophysiology and treatment of FM and related syndromes that have the potential to improve the recognition and management of patients with FM and other conditions with FM-like pain. However, much of the new information has not reached all clinicians, especially primary care clinicians, who have the greatest potential to use this new knowledge to positively impact their patients’ lives. Furthermore, there are persistent misconceptions about FM and a lack of consensus regarding the diagnosis and treatment of FM. This paper presents a framework for future global efforts to improve the understanding and treatment of FM and other associated chronic pain syndromes, disseminate research findings, identify ways to enhance advocacy for these patients, and improve global efforts to collaborate and reach consensus about key issues related to FM and chronic pain in general.

Indirect measurement of disc hydration can be obtained through measures of spinal height using stadiometry. However, specialised stadiometers for this are often custom-built and expensive. Generic wall-mounted stadiometers alternatively are common in clinics and laboratories. This study examined the reliability of a custom set-up utilising a wall-mounted stadiometer for measurement of spinal height using custom built wall mounted postural rods. Twelve participants with non-specific chronic low back pain (CLBP; females n = 5, males n = 7) underwent measurement of spinal height on three separate consecutive days at the same time of day where 10 measurements were taken at 20 s intervals. Comparisons were made using repeated measures analysis of variance for 'trial' and 'gender'. There were no significant effects by trial or interaction effects of trial x gender. Intra-individual absolute standard error of measurement (SEM) was calculated for spinal height using the first of the 10 measures, the average of 10 measures, the total shrinkage, and the rate of shrinkage across the 10 measures examined as the slope of the curve when a linear regression was fitted. SEMs were 3.1 mm, 2.8 mm, 2.6 mm and 0.212, respectively. Absence of significant differences between trials and the reported SEMs suggests this custom set-up for measuring spinal height changes is suitable use as an outcome measure in either research or clinical practice in participants with CLBP.

Chronic pain, most often due to haemophilic arthropathy, is a pervasive problem in persons with haemophilia (PWH) that adversely impacts function and quality of life. PWH with inhibitors and older PWH may be especially vulnerable to progressive arthropathy and resulting chronic pain. The development of chronic pain from acute pain involves a complex interplay of biological and psychosocial factors that may all contribute to the perpetuation of chronic pain and the outcome of therapy. In the absence of evidence-based guidelines, an individualized, multimodal approach to chronic pain management is proposed, as it is in individuals without haemophilia who have chronic pain. Pharmacological treatment is central to the management of chronic pain and must be modified based on pain intensity, ongoing response to therapy and the risk for adverse events. Non-pharmacological interventions, including physiotherapy, complementary treatments and surgical (e.g. orthopaedic) or other invasive procedures, may be integral to chronic pain management in this population. Ongoing psychosocial assessment is critical to identify those factors that may be contributing to the perpetuation of chronic pain or acting as barriers to effective management. Additional study is needed to identify optimal pharmacological treatments for chronic pain in PWH based on the unique pathophysiology of haemophilic arthropathy and on risk profile. Systematic determination of the particular psychosocial factors impacting the experience and management of chronic pain in PWH would likewise add value to the treatment of this pervasive problem.

Full Text Available Chronic pelvic pain (CPP is a common condition that has a major impact on the quality of life of both men and women. Male CPP is usually attributable to well-defined urogenital conditions (most frequently infectious/non infectious prostatic diseases or musculoskeletal or bowel diseases, whereas the features of female CPP are much more complex and are of particular clinical and epidemiological importance. It is a multifactorial syndrome that can be due to diseases of the urogenital, gastrointestinal, or musculoskeletal systems, or to neurological or neuropsychiatric disorders. It is not always easy to identify its predominant pathogenesis, although it often occurs as a central sensitization syndrome triggered by an initial stimulus which is no longer detectable and only manifests itself clinically through pain. In this respect, there are some very interesting relationships between vulvodynia and fibromyalgic syndrome, as identified in a preliminary study of women with chronic musculoskeletal pain in which it was demonstrated that vulvar pain plays an important role, although it is often overlooked and undiagnosed.

The comorbidity integrated by chronic pain and depression is very common. The somatoform depressive symptoms appear often as diferent types of pain. Amon them premenstrual pain and fibromialgia are some of the most important clinical pictures. Chronic pain leads to depression as a consequence of these three kinds of factors: biomedical, psychosocial (passive attitude, disability) and pharmacological agents. Copping and acceptance of chronic pain is associated with lower pain intensity, less depression and less psychosocial disability. The appropriate use of analgesics in the management of chronic pain demands individualization. Several antidepressants have possitive effects on pain syndrom. Depression is underrecognized ad undertreated above all in patients with chronic pain. In order screening the depression seven ways are described here: personal and family history, type of the personality, clinic and evolutive aspects of somatoform symptom, search of other depressive symptoms and positive therapeutic effect determinated by an antidepressant.

This prospective study of acute and sub-acute low back pain (LBP) patients was conducted to assess whether attentional biases predicted chronic pain status 3 and 6 months later. The attentional biases of 100 LBP patients were assessed within 3 months of developing pain and 6 months later. Participants also completed measures associated with outcome at 3 assessment points: baseline, 3 and 6 months later. Current pain status was assessed at follow-ups. Patients were classified as those that met standard criteria for chronic pain or those who did not (i.e., the comparison group). At baseline, participants demonstrated a bias toward sensory pain words. However, biases toward sensory pain words did not differentiate those who subsequently developed chronic pain and those who did not at either follow-up. The same bias was observed 6 months later, but again it failed to distinguish between the chronic pain and comparison groups. However, subjects who developed chronic pain at both 3 (n=22) and 6 (n=21) months demonstrated biases away from affective pain words at baseline but not 6 months later, in comparison to other participants. These results remained significant in multivariate analyses. These findings are consistent with patterns observed in the previous research, and suggest that avoidance of emotionally laden pain-related stimuli (i.e., affective pain words) is associated with negative outcomes for LBP patients in the acute and sub-acute phase. This research suggests that attentional biases in relation to pain-related stimuli are important for the development of chronic pain, but are more complex than initially thought. PMID:24028848

Full Text Available The pain associated with spondyloarthritis (SpA can be intense, persistent and disabling. It frequently has a multifactorial, simultaneously central and peripheral origin, and may be due to currently active inflammation, or joint damage and tissue destruction arising from a previous inflammatory condition. Inflammatory pain symptoms can be reduced by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in the mechanisms that regulate central pain, as in the case of the chronic widespread pain (CWP that characterises fibromyalgia (FM. The importance of distinguishing SpA and FM is underlined by the fact that SpA is currently treated with costly drugs such as tumour necrosis factor (TNF inhibitors, and direct costs are higher in patients with concomitant CWP or FM than in those with FM or SpA alone. Optimal treatment needs to take into account symptoms such as fatigue, mood, sleep, and the overall quality of life, and is based on the use of tricyclic antidepressants or selective serotonin reuptake inhibitors such as fluoxetine, rather than adjustments in the dose of anti-TNF agents or disease-modifying drugs.
Chronic painful muscle conditions include non-inflammatory and inflammatory illnesses. This review is focused on chronic non-inflammatory pain conditions such as myofascial pain syndrome (MPS) and fibromyalgia syndrome (FM), and will not discuss metabolic, genetic or inflammatory muscle diseases such as McArdle's disease, muscular dystrophy, polymyositis, dermatomyositis, or inclusion body myositis.
Full Text Available : BACKGROUND: Chronic post herniorrhaphy groin pain is defined as pain lasting > 6 months after surgery, which is one of the most important complication occurring after inguinal hernia repair, occurs with greater frequency than previously thought. Chronic groin pain is one of the most significant complications following inguinal hernia repair, and majority of chronic pain has been attributed to ilioinguinal nerve entrapment. Various other factors are involved in development of chronic pain. MATERIAL AND METHODS: Patients undergoing elective inguinal hernioplasty in Victoria hospital from November2011 to May 2013 were included in the study. A total of 227 patients met the inclusion criteria and were available for follow up at end of six months. A detailed preoperative, intraoperative and post-operative details of cases were recorded according to proforma. The postoperative pain and pain at two, seven days and at end of six months were recorded on a VAS scale. RESULTS: Chronic pain at six month follow up was present in 89 patients constituting 39.4% of all patients undergoing hernia repair. It was seen that 26.9% without preoperative pain developed chronic pain whereas 76.7 % of patients with preoperative pain developed chronic pain. Patients with significant preoperative pain had higher chances of developing chronic pain (p<.0001. Preemptive analgesia failed to show statistical significance in development of chronic pain (p=0.079. Nerve injury were present in 22 of cases it was found that nerve injury significantly affected development of chronic pain (p=0.001.Post-operative infiltration of local anesthesia was practiced in 16.3 % of cases and it was found that local infiltration at incision site significantly reduced incidence of chronic pain (p=0.001.Postoperative complications in the form of hematoma, seroma or infection was present in 8.5 % of cases. It was found that post-operative complication not only increased early post-operative pain

Full Text Available The chronic pain “three-step” OMS ladder is likely to be revised, in order to introduce a “fourth step” including clinical indications for the invasive analgesic procedures. The number of patients who undergo such procedures is likely to increase, as well as modern oncology and palliative medicine development. Most of invasive approaches include central (spinal neuromodulation and peripheral (gangliar neurolysis, percutaneous vertebral reduction techniques, as well as pharmacological (opioids and adiuvants, chemical (alcohol and physical (electrical stimulation, thermic neurolysis means. Rarely effective as unique therapies, invasive procedures have to be accurately patient-selected and considered supplementary to conservative approaches, in order to minimize the adverse events deriving from a long term opioid therapy. In the near future, the development of both pain science and biomedical technology will probably be accompanied by the improvement of the knowledge regarding the recourse to invasive analgesic procedures.

Full Text Available OBJECTIVES: Catastrophizing is often the primary target of the cognitive-behavioral treatment of chronic pain. Recent literature on acceptance and commitment therapy (ACT suggests an important role in the pain experience for the concepts mindfulness and acceptance. The aim of this study is to examine the influence of mindfulness and general psychological acceptance on pain-related catastrophizing in patients with chronic pain. METHODS: A cross-sectional survey was conducted, including 87 chronic pain patients from an academic outpatient pain center. RESULTS: The results show that general psychological acceptance (measured with the AAQ-II is a strong predictor of pain-related catastrophizing, independent of gender, age and pain intensity. Mindfulness (measured with the MAAS did not predict levels of pain-related catastrophizing. DISCUSSION: Acceptance of psychological experiences outside of pain itself is related to catastrophizing. Thus, acceptance seems to play a role in the pain experience and should be part of the treatment of chronic pain. The focus of the ACT treatment of chronic pain does not necessarily have to be on acceptance of pain per se, but may be aimed at acceptance of unwanted experiences in general. Mindfulness in the sense of "acting with awareness" is however not related to catastrophizing. Based on our research findings in comparisons with those of other authors, we recommend a broader conceptualization of mindfulness and the use of a multifaceted questionnaire for mindfulness instead of the unidimensional MAAS.

Following the widespread use of mesh repairs, recurrence rates after inguinal hernia surgery have become acceptable and focus has shifted from recurrence to chronic pain. Although pain can be controlled with analgesics, chronic postsurgical pain is a major clinical problem, which can significantly influence the patient's quality of life. The rate of chronic pain after inguinal hernia mesh repair can reach 51.6%. The reasons for posthernioplasty chronic pain are often unclear. It has been linked to nerve injury and nerve entrapment, but there is also association between the rate of chronic pain and the type of mesh used for hernia repair. As there are >160 meshes available in the market, it is difficult to choose a mesh whose usage would result in the best outcome. Different mesh characteristics have been studied, among them weight of mesh has probably gained the most attention. The choice of adequate therapy for chronic groin pain after inguinal hernia repair is controversial. The European Hernia Society recommends that a multidisciplinary approach at a pain clinic should be considered for the treatment of chronic postoperative pain. Although surgical treatment of chronic posthernioplasty pain is limited because of the lack of relevant research data, resection of entrapped nerves, mesh removal in the case of mesh related pain or removal of fixation sutures can be beneficial for the patient with severe pain after inguinal hernia surgery. One drawback of published studies is the lack of consensus over definition of chronic pain, which makes it complicated to compare the results of different studies and to conduct meta-analyses and systematic reviews. Therefore, a uniform definition of chronic pain and its best assessment methods should be developed in order to conduct top quality multicenter randomized trials. Further research to develop meshes with optimal parameters is of vital importance and should be encouraged. PMID:26567717

BACKGROUND: In contrast to the well-described 10% risk of chronic pain affecting daily activities after adult groin hernia repair, chronic pain after childhood groin hernia repair has never been investigated. Studies of other childhood surgery before the age of 3 months suggest a risk of increased...... pain responsiveness later in life, but its potential relationship to chronic pain in adult life is unknown. METHODS: This was a nationwide detailed questionnaire study of chronic groin pain in adults having surgery for a groin hernia repair before the age of 5 years (n = 1075). RESULTS: The response...... the age of 3 months (n = 122) did not report groin pain more often or with higher intensity than other patients did. CONCLUSIONS: Groin pain in adult patients operated on for a groin hernia in childhood is uncommon and usually mild and occurs in relation to physical activity. Operation before the age...

Full Text Available Daniela Roditi, Michael E Robinson, Nola LitwinsDepartment of Clinical and Health Psychology, University of Florida, Gainesville, FL, USAAbstract: The present study measured the effects of catastrophizing self-statements and positive coping self-statements on cold pressor-induced pain. Participants were 58 adult chronic pain patients with current facial pain. It was hypothesized that catastrophizing would lead to a decrease in pain endurance whereas positive coping would lead to an increase in pain endurance. It was also hypothesized that catastrophizing would lead to an increase in peak pain intensity whereas positive coping would lead to a decrease in peak pain intensity. At pretest, participants submerged their nondominant hand in the cold pressor. Pain sensitivity ranges (PSR were subsequently determined by calculating the difference between tolerance and threshold times. Ratings of peak pain intensity were measured using a pressure sensitive bladder/transducer. Participants underwent random assignment to either a catastrophizing group or a positive coping self-statement group. ANCOVA results revealed that on average, participants employing catastrophizing statements as a coping strategy experienced significantly lower PSR (M = 35.53, SD = 39.71 compared to participants employing positive coping self-statements (M = 73.70, SD = 86.14 when controlling for pretest PSR. Group assignment had no significant influence on peak pain intensity ratings. Thus, our results reveal that manipulation of coping causes changes in pain endurance.Keywords: catastrophizing, coping, expectation, pain sensitivity
Full Text Available Persistent (or chronic pain occurs with a prevalence of about 10% in the adult population, and chronic soft tissue pain is especially problematic. Criteria for diagnosis of these soft tissue pain disorders appear to suffer from specificity problems, even though they appear to be sensitive in distinguishing normal from soft tissue pain sufferers. A few decades ago the term 'neuraesthenia' was used as a diagnosis in individuals who now would probably be diagnosed as suffering from fibromyalgia, chronic fatigue and anxiety disorders with fatigue. Soft tissue pain provokes skepticism, especially among third-party payers, and controversy among clinicians. Recent epidemiological studies have demonstrated sex differences in the prevalence of widespread pain and multiple tender points, which are distributed variably throughout the adult population and tend to be correlated with subjective symptoms. Although there is a tendency for these syndromes to persist, follow-up studies show that they tend to vary in extent and sometimes show remissions over longer follow-up, casting doubt about the distinctions between chronic diffuse pains and localized chronic soft tissue pains. Because both accidents and soft tissue pains are relatively prevalent problems, the possibility of chance coincidence of accident and chronic soft tissue pain in an individual creates the need to be cautious in attributing these syndromes to specific accidents in medicolegal situations. At the same time, the available evidence does not support a generally dismissive attitude towards these patients.

Chronic pain is a public health concern affecting 20-30% of the population of Western countries. Although there have been many scientific advances in the understanding of the neurophysiology of pain, precisely assessing and diagnosing a patient's chronic pain problem is not straightforward or well-defined. How chronic pain is conceptualized influences how pain is evaluated and the factors considered when making a chronic pain diagnosis. There is no one-to-one relationship between the amount or type of organic pathology and pain intensity, but instead, the chronic pain experience is shaped by a myriad of biomedical, psychosocial (e.g. patients' beliefs, expectations, and mood), and behavioural factors (e.g. context, responses by significant others). Assessing each of these three domains through a comprehensive evaluation of the person with chronic pain is essential for treatment decisions and to facilitate optimal outcomes. This evaluation should include a thorough patient history and medical evaluation and a brief screening interview where the patient's behaviour can be observed. Further assessment to address questions identified during the initial evaluation will guide decisions as to what additional assessments, if any, may be appropriate. Standardized self-reported instruments to evaluate the patient's pain intensity, functional abilities, beliefs and expectations, and emotional distress are available, and can be administered by the physician, or a referral for in depth evaluation can be made to assist in treatment planning.

Cognitive factors such as catastrophic thoughts regarding pain, and conversely, one's acceptance of that pain, may affect emotional functioning among persons with chronic pain conditions. The aims of the present study were to examine the effects of both catastrophizing and acceptance on affective ratings of experimentally induced ischemic pain and also self-reports of depressive symptoms. Sixty-seven individuals with chronic back pain completed self-report measures of catastrophizing, acceptance, and depressive symptoms. In addition, participants underwent an ischemic pain induction procedure and were asked to rate the induced pain. Catastrophizing showed significant effects on sensory and intensity but not affective ratings of the induced pain. Acceptance did not show any significant associations, when catastrophizing was also in the model, with any form of ratings of the induced pain. Catastrophizing, but not acceptance, was also significantly associated with self-reported depressive symptoms when these two variables were both included in a regression model. Overall, results indicate negative thought patterns such as catastrophizing appear to be more closely related to outcomes of perceived pain severity and affect in persons with chronic pain exposed to an experimental laboratory pain stimulus than does more positive patterns as reflected in measures of acceptance.

Chronic pain may recur after initial response to strong opioids in both patients with cancer and patients without cancer or therapy may be complicated by intolerable side effects. When minimally invasive interventional pain management techniques also fail to provide satisfactory pain relief, continuous intrathecal analgesic administration may be considered. Only 3 products have been officially approved for long-term intrathecal administration: morphine, baclofen, and ziconotide. The efficacy of intrathecal ziconotide for the management of patients with severe chronic refractory noncancer pain was illustrated in 3 placebo-controlled trials. A randomized study showed this treatment option to be effective over a short follow-up period for patients with pain due to cancer or AIDS. The efficacy of intrathecal opioid administration for the management of chronic noncancer pain is mainly derived from prospective and retrospective noncontrolled trials. The effect of intrathecal morphine administration in patients with pain due to cancer was compared with oral or transdermal treatment in a randomized controlled trial, which found better pain control and fewer side effects with intrathecal opioids. Other evidence is derived from cohort studies. Side effects of chronic intrathecal therapy may either be technical (catheter or pump malfunction) or biological (infection). The most troublesome complication is, however, the possibility of granuloma formation at the catheter tip that may induce neurological damage. Given limited studies, the evidence for intrathecal drug administration in patients suffering from cancer-related pain is more compelling than that of chronic noncancer pain. PMID:24118774

Full Text Available Osteomalacia is a form of metabolic bone disease that can present as chronic pain. A 36-year-old woman presented with a three-year history of bilateral leg and back pain, and proximal leg weakness. Repeated consultations and investigations failed to discover a cause for her pain, and a diagnosis of chronic benign pain was made. She was admitted to hospital where the bone scan, laboratory investigation and bone biopsy established a diagnosis of renal phosphate-wasting adult-onset rickets (osteomalacia. Radiographs of the hip and magnetic resonance imaging revealed bilateral femoral neck fractures and segmental, avascular necrosis of the femoral heads. The patient was treated with high dose phosphate and vitamin D with marked relief of pain. Osteomalacia should be considered in unusual cases of intractable chronic pain.
Full Text Available Introduction: The affective component of pain incorporates various emotions, primarily negative in quality. A great emphasis has been traditionally given to the role of depression and anxiety in chronic pain. More recently, the focus has been directed towards hostility and anger, as fundamental components of the emotional experience of chronic pain. Objective: The aim of this article is to present a literature’s review about the association between chronic pain, anger and hostility. Discussion: Patients with several chronic disorders are characterized by high levels of trait anger and hostility. On the other hand, the manner in which angry feelings are typically handled (anger management style, especially the marked tendency to suppress or express angry feelings, is a particularly important determinant of the chronic pain severity. Conclusion: Hostility and anger are involved in the development, maintenance and treatment of chronic pain. Further research is needed to clarify its relationship with chronic pain and to evaluate the effects of anger management on treatment outcomes.

Background Myofascial pain syndrome (MPS) is a regional musculoskeletal pain disorder that is caused by myofascial trigger points. The objective of this study was to determine the prevalence of MPS among chronic back pain patients, as well as to identify risk factors and the outcome of this disorder. Methods This was a prospective observational study involving 126 patients who attended the Pain Management Unit for chronic back pain between 1st January 2009 and 31st December 2009. Data examined included demographic features of patients, duration of back pain, muscle(s) involved, primary diagnosis, treatment modality and response to treatment. Results The prevalence of MPS among chronic back pain patients was 63.5% (n = 80). Secondary MPS was more common than primary MPS, making up 81.3% of the total MPS. There was an association between female gender and risk of developing MPS (χ2 = 5.38, P = 0.02, O.R. = 2.4). Occupation, body mass index and duration of back pain were not significantly associated with MPS occurrence.

This study aimed to investigate the risk of death, development of cancer, and hospital inpatient admissions resulting from injuries and toxicity/poisoning among opioid users with chronic noncancer pain. A population-based cohort of 13,127 adults, who have participated in the Danish Health Interview...... Surveys in 2000 or 2005 and have been followed up prospectively by registers until the end of 2011, were classified according to the absence or presence of chronic pain (ie, pain lasting ⩾ 6 months) and long-term or short-term opioid use (individuals using at least 1 prescription per month for 6 months...... in the previous year and at least 1 prescription in the previous year, respectively). The risk of all-cause mortality was 1.72 (95% confidence interval [CI]=1.23-2.41) times higher among long-term opioid users than among individuals without chronic pain. The risk of death was lower, but still significantly higher...

This study reports chronic pain prevalence in a randomly selected sample of the adult Australian population. Data were collected by Computer-Assisted Telephone Interview (CATI) using randomly generated telephone numbers and a two-stage stratified sample design. Chronic pain was defined as pain experienced every day for three months in the six months prior to interview. There were 17,543 completed interviews (response rate=70.8%). Chronic pain was reported by 17.1% of males and 20.0% of females. For males, prevalence peaked at 27.0% in the 65--69 year age group and for females, prevalence peaked at 31.0% in the oldest age group (80--84 years). Having chronic pain was significantly associated with older age, female gender, lower levels of completed education, and not having private health insurance; it was also strongly associated with receiving a disability benefit (adjusted OR=3.89, Punemployment benefit (adjusted OR=1.99, Punemployed for health reasons (adjusted OR=6.41, Pinsurance. There were strong associations between having interfering chronic pain and receiving disability benefits (adjusted OR=3.31, Punemployed due to health reasons (adjusted OR=7.94, P<0.001, respectively). The results show that chronic pain impacts upon a large proportion of the adult Australian population, including the working age population, and is strongly associated with markers of social disadvantage.

Full Text Available The article considers the mechanisms of chronic low back pain. Three pathophysiological mechanisms: nociceptive, neurogenic (neuropathic, and psychogenic are noted to be involved in the development of pain syndrome. The role of cellular and molecular changes in the posterior horn and in the somatosensory dysregulated mechanism of neuropathic pain is shown. Immunological processes, including neurohumoral (serotoninergic and hormonal (sex hormones and specific proteins ones, play an important role in the development of pain. The generalization and further study of these mechanisms are embodied in approaches to therapy for pain syndromes and hence these require analysis and further investigation.

Low back pain is an extremely common presenting complaint that occurs in upward of 80% of persons. Treatment of an acute episode of back pain includes relative rest, activity modification, nonsteroidal anti-inflammatories, and physical therapy. Patient education is also imperative, as these patients are at risk for further future episodes of back pain. Chronic back pain (>6 months' duration) develops in a small percentage of patients. Clinicians' ability to diagnose the exact pathologic source of these symptoms is severely limited, making a cure unlikely. Treatment of these patients should be supportive, the goal being to improve pain and function. PMID:26614726

Back pain is a significant medical problem and one of the most common causes of medical consultations and missed work. In acute low back pain, patients with "red flags" indicating a serious underlying spinal or extraspinal disease must be identified by medical evaluation. Most cases of acute back pain are non-specific, and education, physical activity and pain medication is recommended. In addition, yellow flags (risks of developing chronic pain) should be recognized. The management of low back pain has been addressed by the German National Disease Management Guideline (NVL) low back pain published in 2010. This guideline evaluates the evidence and effectiveness of diagnostic and therapeutic interventions with a focus on nonspecific back pain. For chronic nonspecific low back pain intervention based on nondrug and drug therapy and a multiprofessional assessment is recommended. In patients with chronic inflammatory low back pain with onset before the age of 45, rheumatic spondyloarthritis should be considered. Recently, a guideline (S3-Leitlinie) for the management of axial spondyloarthritis including ankylosing spondylitis has become available. It provides evidence of physical and drug therapy including nonsteroidal antirheumatic and Tumor necrosis factor (TNF) inhibitor therapy. PMID:25465277
Full Text Available Chronic non malignant pain is always a therapeutic challenge of great significance because a inappropriate and insufficient treatment is able to reduce the life’s quality of the patients. Many therapeutic strategies were used to solve these issues, no one exhaustive. In the treatment of cancer pain, opiates use is common, is not the same for the chronic non-malignant pain. The fear of possible side effects (addiction, tolerance, respiratory depression restrain the therapist to apply this remedy. The aim of our work is to demonstrate how a correct application of the opiates in patients with chronic benign pain is not only possible but also desirable to relieving the pain and improving the quality of life.

Chronic, debilitating abdominal pain is arguably the most important component of chronic pancreatitis, leading to significant morbidity and disability. Attempting to treat this pain, which is too often unsuccessful, is a frustrating experience for physician and patient. Multiple studies to improve understanding of the pathophysiology that causes pain in some patients but not in others have been performed since the most recent reviews on this topic. In addition, new treatment modalities have been developed and evaluated in this population. This review discusses new advances in neuroscience and the study of visceral pain mechanisms, as well as genetic factors that may play a role. Updates of established therapies, as well as new techniques used in addressing pain from chronic pancreatitis, are reviewed. Lastly, outcome measures, which have been highly variable in this field over the years, are addressed. PMID:17533083

Full Text Available Serotonin is a monoamine neurotransmitter that plays a major role in both nociception and mood regulation. Alterations in the 5-hydroxytryptophan (5HT system have been reported in chronic pain patients. In recent years, Selective Serotonin Reuptake Inhibitors (SSRIs have been suggested as an alternative treatment for chronic pain due to the fact that they are better tolerated presenting less secondary effects than other antidepressants such as tricyclic antidepressants. Although several clinical trials have been published, the effectiveness of SSRI as treatment for pain conditions is inconclusive. This review aims to summarise what is known, regarding the effectiveness of SSRI as a treatment for chronic pain conditions in adults. A total of 36 studies involving a total of 1898 participants were included in this review. Of the 36 trials included in the review, 2 used zimelidine as treatment, 3 used escitalopram, 4 used fluvoxamine, 4 used sertraline, 6 used citalopram, 8 used paroxetine, 9 used fluoxetine, and one used both citalopram and paroxetine. Because the trials included in this review are quite heterogeneous, only qualitative analyses were performed. SSRI seems to have an effect on most of chronic pain conditions; however, further clinical trials with good methodology leading to low risk of bias are needed in order to conclude once and for all the effect of this drug class as treatment for chronic pain conditions.

A child or adolescent can suffer from chronic pain. Whatever the causes, it can trap the child in a specific process whereby they focus on the pain, fearing that it will appear and experiencing anxiety. Hypno-analgesia and hypnotherapy enable them to escape this process and find within themselves the capacity to face up to the pain. Moreover, these techniques offer them an autonomy which they can use in all areas of their life. PMID:24779171

Full Text Available Abstract An understanding of how the brain changes in chronic pain or responds to pharmacological or other therapeutic interventions has been significantly changed as a result of developments in neuroimaging of the CNS. These developments have occurred in 3 domains : (1 Anatomical Imaging which has demonstrated changes in brain volume in chronic pain; (2 Functional Imaging (fMRI that has demonstrated an altered state in the brain in chronic pain conditions including back pain, neuropathic pain, and complex regional pain syndromes. In addition the response of the brain to drugs has provided new insights into how these may modify normal and abnormal circuits (phMRI or pharmacological MRI; (3 Chemical Imaging (Magnetic Resonance Spectroscopy or MRS has helped our understanding of measures of chemical changes in chronic pain. Taken together these three domains have already changed the way in which we think of pain – it should now be considered an altered brain state in which there may be altered functional connections or systems and a state that has components of degenerative aspects of the CNS.
Full Text Available Abstract Background Little information is available on the problem of chronic pain among homeless individuals. This study aimed to describe the characteristics of and treatments for chronic pain, barriers to pain management, concurrent medical conditions, and substance use among a representative sample of homeless single adult shelter users who experience chronic pain in Toronto, Canada. Methods Participants were randomly selected at shelters for single homeless adults between September 2007 and February 2008 and screened for chronic pain, defined as having pain in the body for ≥ 3 months or receiving treatment for pain that started ≥ 3 months ago. Cross-sectional surveys obtained information on demographic characteristics, characteristics of and treatments for chronic pain, barriers to pain management, concurrent medical conditions, and substance use. Whenever possible, participants' physicians were also interviewed. Results Among 152 homeless participants who experienced chronic pain, 11 (8% were classified as Chronic Pain Grade I (low disability-low intensity, 47 (32% as Grade II (low disability-high intensity, 34 (23% as Grade III (high disability-moderately limiting, and 54 (37% as Grade IV (high disability-severely limiting. The most common self-reported barriers to pain management were stress of shelter life, inability to afford prescription medications, and poor sleeping conditions. Participants reported using over-the-counter medications (48%, street drugs (46%, prescribed medications (43%, and alcohol (29% to treat their pain. Of the 61 interviewed physicians, only 51% reported treating the patient's pain. The most common physician-reported difficulties with pain management were reluctance to prescribe narcotics due to the patient's history of substance abuse, psychiatric comorbidities, frequently missed appointments, and difficulty getting the patient to take medications correctly.

Full Text Available Background. Chronic pain is associated with increased morbidity and mortality, predominated by cardiovascular disease and cancer. Investigating related risk factor measures may elucidate the biological burden of chronic pain. Objectives. We hypothesized that chronic pain severity would be positively associated with the risk factor composite. Methods. Data from 12,982 participants in the 6th Tromsø study were analyzed. Questionnaires included demographics, health behaviors, medical comorbidities, and chronic pain symptoms. The risk factor composite was comprised of body mass index, fibrinogen, C-reactive protein, and triglycerides. Chronic pain severity was characterized by frequency, intensity, time/duration, and total number of pain sites. Results. Individuals with chronic pain had a greater risk factor composite than individuals without chronic pain controlling for covariates and after excluding inflammation-related health conditions (p<0.001. A significant “dose-response” relationship was demonstrated with pain severity (p<0.001. In individuals with chronic pain, the risk factor composite varied by health behavior, exercise, lower levels and smoking, and higher levels. Discussion. The risk factor composite was higher in individuals with chronic pain, greater with increasing pain severity, and influenced by health behaviors. Conclusions. Identification of a biological composite sensitive to pain severity and adaptive/maladaptive behaviors would have significant clinical and research utility.

Full Text Available This review aims at presenting a current view on the physiopathologic mechanisms associated with temporomandibular disorders (TMDs. While joint pain is characterized by a well-defined inflammatory process mediated by tumor necrosis factor-α and interleukin, chronic muscle pain presents with enigmatic physiopathologic mechanisms, being considered a functional pain syndrome similar to fibromyalgia, irritable bowel syndrome, interstitial cystitis and chronic fatigue syndrome. Central sensitization is the common factor unifying these conditions, and may be influenced by the autonomic nervous system and genetic polymorphisms. Thus, TMDs symptoms should be understood as a complex response which might get worse or improve depending on an individual's adaptation.

In the past decade there has been a dramatic increase in (1) understanding the neurophysiological components of the pain experiences, (2) randomized clinical trials testing the efficacy of hypnotic treatments on chronic pain, and (3) laboratory research examining the effects of hypnosis on the neurophysiological processes implicated in pain. Work done in these areas has not only demonstrated the efficacy of hypnosis for treating chronic pain but is beginning to shed light on neurophysiological processes that may play a role in its effectiveness. This paper reviews a selection of published studies from these areas of research, focusing on recent findings that have the most potential to inform both clinical work and research in this area. The paper concludes with research and clinical recommendations for maximizing treatment efficacy based on the research findings that are available. PMID:24073099

Full Text Available Clinicians often encounter patients who present with both chronic pain and elevated levels of anxiety. In some cases, the source of the anxiety is vague and diffuse. For others, there is an identifiable precipitating object, event or situation. For example, some patients with chronic pain are able to attribute their anxiety to the possibility of not regaining lost functional abilities, financial difficulties, feelings of social inadequacy, or uncertainty about the meaning and consequences of pain. The association between chronic pain and anxiety may not be particularly surprising when one considers that, in the acute phase, both pain and target-oriented anxiety (or fear motivate actions that serve to minimize the threat and maximize the likelihood of successful escape. As well, their neurobiology, while distinct, interacts in the reticular system (1. Evaluations of the association between chronic pain and fear-relevant constructs were initiated in the 1960s and 1970s (2,3. It has only been of late, however, that theorists and researchers have begun to focus their attention on delineating the precise nature of the relationship and its specific implications for the assessment and management of pain.

Chronic low back pain (CLBP) is a significant healthcare problem, and many individuals with CLBP remain unresponsive to available interventions. Previous research suggests that hypnosis is effective for many chronic pain conditions; however, data to support its efficacy for CLBP are outdated and have been limited primarily to case studies. This pilot study indicated that a brief, 4-session standardized self-hypnosis protocol, combined with psycho-education, significantly and substantially reduced pain intensity and pain interference. Significant session-to-session improvements were also noted on pain ratings and mood states; however, follow-up data suggest that these benefits may not have been maintained across time in this sample. These findings need to be replicated and confirmed in a larger clinical trial, which could also assess the long-term effects of this treatment. PMID:20183738

Many dysfunctional and chronic pain conditions overlap. This review describes the different modes of chronic deregulation of the adaptive response to stress which may be a common factor for these conditions. Several types of dysfunction can be identified within the hypothalamo-pituitary-adrenal axis: basal hypercortisolism, hyper-reactivity, basal hypocortisolism and hypo-reactivity. Neuroactive steroid synthesis is another component of the adaptive response to stress. Dehydroepiandrosterone (DHEA) and its sulfated form DHEA-S, and progesterone and its derivatives are synthetized in cutaneous, nervous, and adipose cells. They are neuroactive factors that act locally. They may have a role in the localization of the symptoms and their levels can vary both in the central nervous system and in the periphery. Persistent changes in neuroactive steroid levels or precursors can induce localized neurodegeneration. The autonomic nervous system is another component of the stress response. Its dysfunction in chronic stress responses can be expressed by decreased basal parasympathethic activity, increased basal sympathetic activity or sympathetic hyporeactivity to a stressful stimulus. The immune and genetic systems also participate. The helper-T cells Th1 secrete pro-inflammatory cytokines such as IL-1-β, IL-2, IL-6, IL-8, IL-12, IFN-γ, and TNF-α, whereas Th2 secrete anti-inflammatory cytokines: IL-4, IL-10, IGF-10, IL-13. Chronic deregulation of the Th1/Th2 balance can occur in favor of anti- or pro-inflammatory direction, locally or systemically. Individual vulnerability to stress can be due to environmental factors but can also be genetically influenced. Genetic polymorphisms and epigenetics are the main keys to understanding the influence of genetics on the response of individuals to constraints. PMID:27262345

Full Text Available Pain is not merely a symptom of disease but a complex independent phenomenon where psychological factors are always present (Sternberg, 1973. Especially by chronic, recurrent pain it's more constructive to think of chronic pain as a syndrome that evolves over time, involving a complex interaction of physiological/organic, psychological, and behavioural processes. Study of chronic recurrent functional pain covers tension form of headache. 50 suffering persons were accidentally chosen among those who had been seeking medical help over more than year ago. We tested their pain intensity and duration, extent of subjective experience of accommodation efforts, temperament characteristics, coping strategies, personal traits, the role of pain in intra- and interpersonal communication. At the end we compared this group with control group (without any manifest physical disorders and with analyse of variance (MANOVA. The typical person who suffers and expects medical help is mostly a woman, married, has elementary or secondary education, is about 40. Pain, seems to appear in the phase of stress-induced psychophysical fatigue, by persons with lower constitutional resistance to different influences, greater irritability and number of physiologic correlates of emotional tensions. Because of their ineffective style of coping, it seems they quickly exhausted their adaptation potential too. Through their higher level of social–field dependence, reactions of other persons (doctor, spouse could be important factors of reinforcement and social learning processes. In managing of chronic pain, especially such as tension headache is, it's very important to involve bio-psychosocial model of pain and integrative model of treatment. Intra- and inter-subjective psychological functions of pain must be recognised as soon as possible.

This study examines maladaptive pain-related fear-avoidance and endurance coping in subgroups of patients with chronic back pain. Hypotheses were derived from the avoidance-endurance model of pain [Hasenbring M. Attentional control of pain and the process of chronification. In: Sandkühler J, Bromm B, Gebhart GF, editors. Progress in pain research, vol. 129. New York: Elsevier; 2000. p. 525-34.], which assumes that endurance coping (cognitive, behavioral tendency to endure severe pain to finish current activities irrespective of pain increases) leads to overuse of muscles, joints, and discs with an increase of pain as long-term consequence. Participants were 120 patients referred for treatment of chronic pain to General Practices. They were classified as 'dysfunctional-DYS' (15.8%), 'interpersonally distressed-ID' (10.8%), and 'adaptive copers-AC' (61.7%) based on the Multidimensional Pain Inventory [Kerns RD, Turk DC, Rudy TE. The West Haven-Yale Multidimensional Pain Inventory (WHYMPI). Pain 1985;23:345-56.] and compared on measures of pain-related fear-avoidance coping (anxiety/depression; help-/hopelessness; catastrophizing; avoidance of social/physical activity) and endurance coping (positive mood; thought suppression; endurance behavior) using the Kiel Pain Inventory [Hasenbring M. The Kiel Pain Inventory-Manual. Three questionnaire scales for assessment of pain-related cognitions, emotions and copying strategies. Bern:Huber; 1994.]. Multivariate analysis of variance indicated that groups differed significantly for pain-related fear-avoidance and endurance coping, even after control for pain intensity and depression. Univariate effects revealed that patients classified as DYS reported more anxiety/depression, help-/hopelessness, and catastrophizing than did those classified as AC. Furthermore, the DYS group showed more thought suppression compared to AC; however, subgroups did not differ significantly with regard to avoidance of social and physical activity

Chronic pain is frequently experienced in adolescents; it affects functionality and requires interventions to decrease the impairments caused by pain. Cognitive behavioral therapy (CBT) has been analyzed in numerous studies that evaluated its effects on reducing the different types of chronic pain in children and adolescents. Interestingly, the outcome of CBT was initially focused on pain intensity, but, because there is no correspondence between children's pain intensity and level of disability, the ability to participate in school and social and recreational activities have been the primary focus of recent studies. There are innovative methods of CBT (such as the third generation of CBT) with and without the use of technology that facilitates the availability of this psychological treatment to adolescents with chronic pain, optimizing its accessibility and comprehensiveness, and maintaining its effectiveness. In the future, specific types of CBT could be specific to the diagnosis of chronic pain in the adolescent, sociodemographics, and other unique features. Parents of children with chronic pain are usually included in these programs, either as coaches in the intervention or as recipients of psychological therapies (including CBT) to optimize benefits. CBT has no adverse effect on chronic pain in adolescents, and there is no literature that makes reference to the effectiveness of CBT in preventing chronic pain in adolescents. A review of the role of CBT in chronic pain in adolescents via a PubMed database search was performed to identify the role of CBT in the management of chronic pain in adolescents.

Full Text Available Long term administration of an opioid drug for chronic nonmalignant pain continues to be controversial, but is no longer uniformly rejected by pain specialists. This is true despite concerns that the regulatory agencies that oversee physician prescribing of opioid drugs continue to stigmatize the practice. The changing clinical perspective has been driven, in part, by widespread acknowledgement of the remarkably favourable outcomes achieved during opioid treatment of cancer pain. These outcomes contrast starkly with popular teaching about chronic opioid therapy and affirm the potential for prolonged efficacy, tolerable side effects, enhanced function associated with improved comfort and minimal risk of aberrant drug-related behaviours consistent with addiction. A large anecdotal experience in populations with nonmalignant pain suggests that these patients are more heterogeneous and that opioid therapy will greatly benefit some and will contribute to negative outcomes for others. The few controlled clinical trials that have been performed support the safety and efficacy of opioid therapy, but have been too limited to ensure generalization to the clinical setting. A critical review of the medical literature pertaining to chronic pain, opioid pharmacology and addiction medicine can clarify misconceptions about opioid therapy and provide a foundation for patient selection and drug administration. The available data support the view that opioids are no panacea for chronic pain, but should be considered in carefully selected patients using clinically derived guidelines that stress a structured approach and ongoing monitoring of efficacy, adverse effects, functional outcomes and the occurrence of aberrant drug-related behaviours.

The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants' body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain.

Neuropathic pain and the other abnormalities of sensation induced by axon injury or by peripheral nerve inflammation should result from functional compensations of the injured neurons during their regeneration. Ectopic distribution of proteins related to Na+, K+ and Ca2+ channels as well as of receptors on both membranes of injured axon and its cell body becomes a main pacemaker from which spontaneous ectopic afferent of primary sensatory neurons and crosstalk between neurons occur. Abnormal ectopic afferent activities lead to disorders of the sensation, such as hyperalgesia, allodynia, spontaneous pain and paraesthesia. Administration of some ion channel agents and/or α2-adrenergic blockers has shown efficiency in preventing neuropathic pain development and in relieving neuropathic pain.

Full Text Available Abstract Background Although clinical guidelines generally portray chronic low back pain as a condition with a poor prognosis this portrayal is based on studies of potentially unrepresentative survival cohorts. The aim of this study is to describe the prognosis of an inception cohort of people with chronic low back pain presenting for primary care. Methods/Design The study will be an inception cohort study with one year follow-up. Participants are drawn from a cohort of consecutive patients presenting with acute low back pain (less than 2 weeks duration to primary care clinics in Sydney, Australia. Those patients who continue to experience pain at three months, and are therefore classified as having chronic back pain, are invited to participate in the current study. The cohort will be followed up by telephone at baseline, 9 months and 12 months after being diagnosed with chronic low back pain. Recovery from low back pain will be measured by sampling three different outcomes: pain intensity, interference with function due to pain, and work status. Life tables will be generated to determine the one year prognosis of chronic low back pain. Prognostic factors will be assessed using Cox regression. Discussion This study will determine the prognosis of chronic non-specific low back pain in a representative cohort of patients sourced from primary care. The results of this study will improve understanding of chronic low back pain, allowing clinicians to provide more accurate prognostic information to their patients.
Effects of nurse-led motivational interviewing of patients with chronic musculoskeletal pain in preparation of rehabilitation treatment (PREPARE) on societal participation, attendance level, and cost-effectiveness: study protocol for a randomized controlled trial.

CAM therapies have become increasingly popular in pediatric populations. Yet, little is known about children's preferences for CAM. This study examined treatment preferences in chronic pediatric pain patients offered a choice of CAM therapies for their pain. Participants were 129 children (94 girls) (mean age = 14.5 years +/- 2.4; range = 8-18 years) presenting at a multidisciplinary, tertiary clinic specializing in pediatric chronic pain. Bivariate and multivariate analyses were used to examine the relationships between CAM treatment preferences and patient's sociodemographic and clinical characteristics, as well as their self-reported level of functioning. Over 60% of patients elected to try at least one CAM approach for pain. The most popular CAM therapies were biofeedback, yoga and hypnosis; the least popular were art therapy and energy healing, with craniosacral, acupuncture and massage being intermediate. Patients with a diagnosis of fibromyalgia (80%) were the most likely to try CAM versus those with other pain diagnoses. In multivariate analyses, pain duration emerged as a significant predictor of CAM preferences. For mind-based approaches (i.e. hypnosis, biofeedback and art therapy), pain duration and limitations in family activities were both significant predictors. When given a choice of CAM therapies, this sample of children with chronic pain, irrespective of pain diagnosis, preferred non-invasive approaches that enhanced relaxation and increased somatic control. Longer duration of pain and greater impairment in functioning, particularly during family activities increased the likelihood that such patients agreed to engage in CAM treatments, especially those that were categorized as mind-based modalities.

The knowledge of biological pain mechanisms are not sufficient for the understanding of patients with chronic pain syndromes such as low back, cervicobrachial and muscle pain. Psychological and psychosocial aspects play important roles in the setting and perpetuation of symptoms. Mood and anxiety disorders, secondary gains such as early retirement and financial compensations, must all be acknowledged by the physician as possible contributors to the symptoms. Abnormal illness behavior may better characterize patients with chronic pain syndromes. Behavior observation, which is akin to medical practice, is therefore a powerful tool in the diagnosis and management of these syndromes. Physicians ought be very careful in not reinforcing the patients already strong organic convictions regarding their symptoms, avoiding making decisions based on patients complaints and alleged disabilities, and assigning poorly defined and disputable diagnosis labels. Society needs also to refrain from policies that encourage abnormal illness behaviors. PMID:10849642

OBJECTIVE: This randomized controlled clinical trial investigated the effects of mindfulness meditation on chronic pain. DESIGN: A total of 109 patients with nonspecific chronic pain were randomized to either a standardized mindfulness meditation program (mindfulness-based stress reduction [MBSR...... randomized patients completed the mindfulness program, while 47 remained in the control group. Data were compared at three time points: at baseline, after completion of the course/waiting period, and at the 6-month follow-up. RESULTS: Significant effect (Cohen's d = 0.39) was found on the primary outcome...... (nonsignificant) effect sizes were found for pain measures. There were no significant differences in the measures just after the intervention vs the 6-month follow-up. CONCLUSION: A standardized mindfulness program (MBSR) contributes positively to pain management and can exert clinically relevant effects...
Full Text Available INTRODUCTION: The principal indication for surgical intervention in chronic pancreatitis is intractable pain. Depending upon the presence of dilated pancreatic ductal system, pancreatic duct drainage procedures and different kinds of pancreatic resections are applied. OBJECTIVE: The objective of the study was to show the most appropriate procedure to gain the most possible benefits in dependence of type of pathohistological process in chronic pancreatitis. METHOD: Our study included 58 patients with intractable pain caused by chronic pancreatitis of alcoholic genesis. The first group consisted of 30 patients with dilated pancreatic ductal system more than 10 mm. The second group involved 28 patients without dilated pancreatic ductal system. Pain relief, weight gain and glucose tolerance were monitored. RESULTS: All patients of Group I (30 underwent latero-lateral pancreaticojejunal - Puestow operation. 80% of patients had no pain after 6 month, 13.6% had rare pain and 2 patients, i.e. 6.4%, who continued to consume alcohol, had strong pain. Group II consisting of 28 patients was without dilated pancreatic ductal system. This group was subjected to various types of pancreatic resections. Whipple procedure (W was done in 6 patients, pylorus preserving Whipple (PPW in 7 cases, and duodenum preserving cephalic pancreatectomy (DPCP was performed in 15 patients. Generally, 89.2% of patients had no pain 6 month after the operation. An average weight gain was 1.9 kg in W group, 2.8 kg in PPW group and 4.1 kg in DPCP group. Insulin-dependent diabetes was recorded in 66.6% in W group, 57.1% in PPW group and 0% in DPCP group. CONCLUSION: According to our opinion, DPCP may be considered the procedure of choice for surgical treatment of pain in chronic pancreatitis in patients without dilatation of pancreas ductal system because of no serious postoperative metabolic consequences.

Self-discrepancy occurs when a person feels the failure to fulfill one's hopes or responsibilities. Although self-discrepancy has been widely examined to elucidate patients' chronic pain adjustment, the underlying mechanism is unclear. The present study proposes that the effect of self-discrepancy on pain outcomes is accounted for by psychological inflexibility, which involves the psychological processes that guide behaviors in the pursuit of goals and values. One-hundred patients with chronic pain were recruited from a public hospital. They were invited to participate in a semi-structured interview regarding their self-discrepancy and complete self-reported questionnaires regarding their psychological inflexibility and pain outcomes. The results confirmed that psychological inflexibility partly accounts for the variance observed between self-discrepancy and pain outcomes. The current study provides additional insight into the mechanism underpinning the impact of self-discrepancy on patients' pain adjustment and offers clinical implications regarding the use of acceptance commitment therapy for chronic pain management.

OBJECTIVES: to measure the pain intensity, identify the disability and depression levels in people with chronic back pain and to correlate these variables. A cross-sectional, descriptive and exploratory study was undertaken at the Pain Treatment Clinic of the University of São Paulo at Ribeirão Preto Hospital das Clínicas, between February and June 2012, after receiving approval from the Ethics Committee at the University of São Paulo at Ribeirão Preto College of Nursing. METHOD: sixty subjects with chronic back pain participated. The instruments used were: the 11-point Numerical Category Scale, the Roland-Morris Disability Questionnaire and the Beck Depression Inventory. To analyze the data, the arithmetic means, standard deviations and Spearman's correlation coefficient were calculated. RESULTS: the findings show that the participants presented high pain, disability and depression levels. The correlation between pain intensity and disability and between pain intensity and depression was positive and weak and, between disability and depression, positive and moderate. CONCLUSION: the study variables showed moderate and weak indices and the mutual correlations were positive. PMID:25296139

Chronic pain in the orofacial region has always been a vexing problem for dentists to diagnose and treat effectively. For trigeminal neuropathic pain, there are 3 medications (gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors) to use plus topical anesthetics that have therapeutic efficacy. For chronic daily headaches (often migraine in origin), 3 prophylactic medications have reasonable therapeutic efficacy (β-blockers, tricyclic antidepressants, and antiepileptic drugs). The 3 Food and Drug Administration-approved drugs for fibromyalgia (pregabalin, duloxetine, and milnacipran) are not robust, with poor efficacy. For osteroarthritis, nonsteroidal anti-inflammatory drugs have therapeutic efficacy and when gastritis contraindicates them, corticosteriod injections are helpful. PMID:27475515

Pain neurophysiology education (PNE) is a distinct form of patient education in pain management. The aims of this study were to explore the experience of PNE for people with chronic pain and to gain insight into their understanding of their pain after PNE. This was a qualitative study, based on Interpretive Phenomenology Analysis, using individual semi-structured interviews to collect data. We recruited a purposive sample of 10 adults with chronic musculoskeletal pain (men and women; mean age 48 years; with a mean pain duration of 9 years) who had recently completed PNE delivered as a single 2-h group session. The interview transcripts were analysed for emerging themes. We identified three themes: perceived relevance for the individual participant; perceived benefits for the individual participant; and evidence of reconceptualisation. An interlinking narrative was the importance of relevance. Eight participants viewed the session as relevant and reported benefits ranging from a better understanding of pain, improved ability to cope with the pain, and some suggested improved levels of physical activity. Four of these participants showed evidence of reconceptualisation, which we describe as partial and patchy. Two participants reported no benefit and did not perceive the material delivered within PNE to be relevant to themselves. Relevance to the individual needs of a person with chronic pain may be a key factor in the success of PNE, and this is a particular challenge when it is delivered in a group situation.
Full Text Available Background: The goals of a chronic pain management clinic includeincreasing patient knowledge about pain, developing pain management skillsand increasing patients’ confidence in their pain management abilities.A Chronic Pain Management Programme (CPMP based on evidence basedguidelines was developed at a chronic pain management clinic to facilitatepatient discharge to a primary healthcare level. Aim: The aim of this study was to explore patient satisfaction with, acceptability of and the perceived success which could be due to the CPMP developed at the Chronic Pain Management Clinic of Groote Schuur Hospital,Cape Town.Methods: Patients (n=14 were referred to the pilot study from the Chronic Pain Management Clinic. A s a pilot, four courses were run over a period ofone year. In order to reach the research aim, an eleven-question, structuredopen-ended interview was conducted with all participants. Results: Fourteen patients enrolled in the CPMP. Responses were favourable with participants emphasising the roleof increased knowledge about pain, the role of exercise and of stress management techniques. Participants also recog-nised a positive change in behaviours and attitudes following participation in the CPMP.Conclusions: Findings suggest that participants found the format of the course acceptable as regards course content,structure and delivery. Participant responses suggest that the course was acceptable and perceived as useful. However,future courses would benefit from refresher courses or structured support groups.

Pharmacological management of severe chronic pain is difficult to achieve with currently available analgesic drugs, and remains a large unmet therapeutic need. The synthetic peptide ziconotide has been approved by the US Food and Drug Administration and the European Medicines Agency for intrathecal treatment of patients with severe chronic pain that is refractory to other treatment modalities. Ziconotide is the first member in the new drug class of selective N-type voltage-sensitive calcium-channel blockers. The ziconotide-induced blockade of N-type calcium channels in the spinal cord inhibits release of pain-relevant neurotransmitters from central terminals of primary afferent neurons. By this mechanism, ziconotide can effectively reduce pain. However, ziconotide has a narrow therapeutic window because of substantial CNS side-effects, and thus treatment with ziconotide is appropriate for only a small subset of patients with severe chronic pain. We provide an overview of the benefits and limitations of intrathecal ziconotide treatment and review potential future developments in this new drug class. PMID:20413151

Full Text Available Rebecca Arden Harris Department of Family and Social Medicine, Montefiore Medical Center/Albert Einstein College of Medicine, Bronx, NY, USAWallace et al1 used an effective combination of qualitative methods, ie, photographs taken by patients with accompanying narratives, interviews, and focus group sessions, to elicit descriptions of the daily realities of living with chronic pain from the patient perspective. The details are intimate and poignant. Patients tell of how they must curtail everyday activities in order to cope with the discomfort, of their frustration in trying to relay their situation to others, and of their despair at the thick-skinned reception they sometimes get because pain presents differently from other ailments. Primary care physicians will learn a lot from these images, particularly with regard to depression as a comorbidity of chronic pain.View orginal paper by Wallace et al

We intend to present some aspects related with the coping process in a person with chronic pain. The presence of pain has implications in daily life activities, such as eating, drinking, sleeping or selfcare. Pain can unchain responses in the person, namely depression, anxiety, isolation, fear of pain and pessimistic thoughts. Thus we verify that in his/her adaptation process to the condition of chronic pain the person needs to integrate some strategies to manage his/her day by day activities. In this article we try to systematize the process where nurses based on Lazarus and Folkman's Model: Stress processing and Coping, can systematize care. In fact, nurses try to help people in the identification of their personal resources as well as the socio-ecological resources. The sense the care process has as a goal is the improvement of the quality of life through pain control and the person's adaptation of his/her condition of health, through development of his/her knowledge and capacities to use the resources, be they personal as instrumental or social.

Background The 9-item STarT-Back screening tool was developed in primary care patients with low back pain (LBP) to identify those at greatest risk for chronic pain and requiring targeted treatment. We conducted a secondary data analysis study to examine the performance of comparable questionnaire items in a sample of primary care patients with well-defined acute LBP. Methods In a prospective cohort study, 605 primary care patients with LBP of less than 30 days answered a questionnaire with 6 items identical and 3 items analogous to the 9-item STarT-Back. Participants were followed up at 6 months and 2 years. STarT-Back rules were applied to classify participant's risk of chronic LBP, and the performance of the screening items in predicting outcomes was assessed using likelihood ratios. Results The proportion of patients with chronic pain at follow-up was considerably lower (6 months: 22%; 2 years: 25%) than in the STarT-Back validation cohort (40%) of patients with pain of any duration. The probability of developing chronic pain given a high-risk designation by items similar to the STarT-Back increased the pre-test probability to 31% and 35%. Likelihood ratios were close to 1. Conclusions A risk classification schema using the recommended cut-off scores with items similar to the STarT-Back in a primary care population with strictly defined acute LBP had limited ability to identify persons who progressed to chronic pain. The results suggest caution when applying the STarT-Back in patients with acute LBP and a need to consider a modification of its cut-offs. PMID:25381748

Epidemiologic studies continue to provide evidence that fibromyalgia is part of a spectrum of chronic widespread pain. The prevalence of chronic widespread pain is several times higher than fibromyalgia as defined by the 1990 American College of Rheumatology guidelines. There is now compelling evidence of a familial clustering of fibromyalgia cases in female sufferers; whether this clustering results from nature or nature remains to be elucidated. A wide spectrum of fibromyalgia-associated symptomatology and syndromes continues to be described. During the past year the association with interstitial cystitis has been explored, and neurally mediated hypotension has been documented in both fibromyalgia and chronic fatigue syndrome. Abnormalities of the growth hormone-insulin-like growth factor-1 axis have been also documented in both fibromyalgia and chronic fatigue syndrome. The commonly reported but anecdotal association of fibromyalgia with whiplash-type neck trauma was validated in a report from Israel. However, unlike North America, 100% of Israeli patients with posttraumatic fibromyalgia returned to work. Basic research in fibromyalgia continues to pinpoint abnormal sensory processing as being integral to understanding fibromyalgia pain. Drugs such as ketamine, which block N-methyl-D-aspartate receptors (which are often upregulated in central pain states) were shown to benefit fibromyalgia pain in an experimental setting. The combination of fluoxetine and amitriptyline was reported to be more beneficial than either drug alone in patients with fibromyalgia. A high prevalence of autoantibodies to cytoskeletal and nuclear envelope proteins was found in chronic fatigue syndrome, and an increased prevalence of antipolymer antibodies was found in symptomatic silicone breast implant recipients who often have fibromyalgia.

The aim of this study was to review published controlled trials of hypnotic treatments for chronic and cancer procedure-related pain in children. Trials were included if participants were 18 years of age or below, were randomized and had populations with chronic pain or cancer procedure-related pain. After the studies were assessed, 12 were selected for review. Although the evidence is limited, the findings indicate that hypnosis is an effective pain-control technique when used with children suffering from cancer procedure-related pain or chronic pain. Further research into the use of hypnosis to manage chronic pain in children should be a priority so that empirically based conclusions can be drawn about the effects of hypnosis on children.

Acceptance and Commitment Therapy (ACT) has been effectively utilized to treat both chronic pain and substance use disorder independently. Given these results and the vital need to treat the comorbidity of the two disorders, a pilot ACT treatment was implemented in individuals with comorbid chronic pain and opioid addiction. This pilot study supported using neurophysiology to characterize treatment effects and revealed that, following ACT, participants with this comorbidity exhibited reductions in brain activation due to painful stimulus and in connectivity at rest.

Full Text Available Chronic pain and posttraumatic stress disorder (PTSD co-occur at high rates, and Veterans from recent wars in Iraq and Afghanistan may be particularly vulnerable to both conditions. The objective of this study was to identify key aspects of chronic pain, cognitions, and psychological distress associated with comorbid PTSD among this sample of Veterans. Baseline data were analyzed from a randomized controlled trial testing a stepped-care intervention for chronic musculoskeletal pain. Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF Veterans with chronic pain only (n = 173 were compared with those with chronic pain and clinically significant posttraumatic stress symptoms (n = 68. Group differences on pain characteristics, pain cognitions, and psychological distress were evaluated. Results demonstrated that OIF/OEF Veterans with comorbid chronic musculoskeletal pain and PTSD experienced higher pain severity, greater pain-related disability and increased pain interference, more maladaptive pain cognitions (e.g., catastrophizing, self-efficacy, pain centrality, and higher affective distress than those with chronic pain alone. Veterans of recent military conflicts in Iraq and Afghanistan may be particularly vulnerable to the compounded adverse effects of chronic pain and PTSD. These results highlight a more intense and disabling pain and psychological experience for those with chronic pain and PTSD than for those without PTSD.

Full Text Available Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child’s pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child’s outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

Engel (1959) suggested that negative physical or emotional experiences in childhood predispose to the development of chronic pain. Studies have shown that physical and sexual abuse in early life is connected with chronic pain. Emotional adversities are much less studied causes contributing to the development of chronic pain and disability. Early emotional abuse, neglect, maltreatment and other adversities are deleterious childhood experiences which, according to Young's schema theory (1990), produce early maladaptive schemas (EMSs). The primary goal of this study was to examine whether early adversities were more common in chronic pain patients than in a control group. A total of 271 (53% women) first-visit chronic pain patients and 331 (86% women) control participants took part in the study. Their socio-demographic data, pain variables and pain disability were measured. To estimate EMSs the Young Schema Questionnaire was used. Chronic pain patients scored higher EMSs reflecting incapacity to perform independently, catastrophic beliefs and pessimism. The most severely disabled chronic pain patients showed an increase in all the EMSs in the Disconnection and Rejection schema domain, namely Abandonment/Instability, Mistrust/Abuse, Emotional Deprivation, Defectiveness/Shame and Social Isolation/Alienation EMSs. The results of the study suggested that chronic pain patients had suffered early emotional maltreatment. PMID:21054422

The cause of chronic pelvic pain syndrome (CPPS) has yet to be established. Since the late 1980s, cytokine, chemokine, and immunological classification studies using human samples have focused on identifying biomarkers for CPPS, but no diagnostically beneficial biomarkers have been identified, and these studies have done little to deepen our understanding of the mechanisms underlying chronic prostatic pain. Given the large number of men thought to be affected by this condition and the ineffective nature of current treatments, there is a pressing need to elucidate these mechanisms. Prostatitis types IIIa and IIIb are classified according to the presence of pain without concurrent presence of bacteria; however, it is becoming more evident that, although levels of bacteria are not directly associated with levels of pain, the presence of bacteria might act as the initiating factor that drives primary activation of mast-cell-mediated inflammation in the prostate. Mast cell activation is also known to suppress regulatory T cell (Treg) control of self-tolerance and also activate neural sensitization. This combination of established autoimmunity coupled with peripheral and central neural sensitization can result in the development of multiple symptoms, including pelvic pain and bladder irritation. Identifying these mechanisms as central mediators in CPPS offers new insight into the prospective treatment of the disease. PMID:24686526

A number of psychosocial factors have been associated with the onset, exacerbation and/or maintenance of chronic pain in adolescents. The present study was conducted to evaluate the relative importance of vulnerability, reinforcement, and modeling. We compared 222 adolescents with chronic pain and no documented physiological etiology (headache, back, limb and abdominal pain) with 148 controls and their (respectively 183 vs. 127) parents. Analyses showed that adolescents with chronic pain are more vulnerable in terms of neuroticism, negative fear of failure, and (less) experienced social acceptance. Contrary to our expectations, the chronic pain group experienced less reinforcement for their pain behavior by both parents and peers than the control group. While the number of pain models was higher in the chronic pain group, no differences were found between their parents and those of the adolescents without chronic pain in pain experience, pain parameters, and pain coping. Regression analyses on the contribution of psychosocial factors to chronic pain and its parameters sustained the positive relation between vulnerability, (less) pain reinforcement, pain models and coping with pain.

A number of psychosocial factors have been associated with the onset, exacerbation and/or maintenance of chronic pain in adolescents. The present study was conducted to evaluate the relative importance of vulnerability, reinforcement, and modeling. We compared 222 adolescents with chronic pain and no documented physiological etiology (headache, back, limb and abdominal pain) with 148 controls and their (respectively 183 vs. 127) parents. Analyses showed that adolescents with chronic pain are more vulnerable in terms of neuroticism, negative fear of failure, and (less) experienced social acceptance. Contrary to our expectations, the chronic pain group experienced less reinforcement for their pain behavior by both parents and peers than the control group. While the number of pain models was higher in the chronic pain group, no differences were found between their parents and those of the adolescents without chronic pain in pain experience, pain parameters, and pain coping. Regression analyses on the contribution of psychosocial factors to chronic pain and its parameters sustained the positive relation between vulnerability, (less) pain reinforcement, pain models and coping with pain. Furthermore, we also found evidence that gender differences have to be taken into account.

Objectives To examine suicidal ideation in individuals with chronic pain, especially change in suicidal thinking following interdisciplinary treatment. Methods Consecutive patients (n = 250) admitted to a 4-week, group-based chronic pain management program completed measures of pain intensity, functional limitations, depressive symptoms, overall distress, pain catastrophizing, self-perceived burden, and suicidal ideation at pre- and post-treatment. Results Before treatment, 30 (12.0%) participants were classified as having a high level of suicidal ideation, 56 (22.4%) had a low level of suicidal ideation, and 164 (65.6%) reported none. Following treatment, there was a significant reduction in suicidal ideation and improvements in all other outcomes, but there were still some individuals with high (n = 22, 8.8%) or low (n = 28, 11.2%) levels at discharge. Patients with high suicidal ideation at baseline differed from those with no suicidal thinking on pre- and post-treatment measures of depression, distress, catastrophizing, and self-perceived burden, but not on pain intensity or functional limitations. Patients high in suicidal ideation endorsed greater pain catastrophizing and self-perceived burden than those low in suicidal thinking. Sustained suicidal ideation after treatment was associated with higher baseline levels of suicidal thinking and self-perceived burden to others, as well as a more limited overall response to treatment. Discussion Suicidal ideation was common in individuals with chronic pain, although mostly at a low level. Interdisciplinary treatment may result in reduced suicidal thinking; however, some patients continue to express thoughts of self-harm. Future studies could examine processes of change and interventions for treatment-resistant suicidal concerns. PMID:24281291

Chronic pain is associated with symptoms that may impair a patient's quality of life, including emotional distress, fatigue, and sleep disturbance. There is a high prevalence of concomitant pain and sleep disturbance. Studies support the hypothesis that sleep and pain have a bidirectional and reciprocal relationship. Clinicians who manage patients with chronic pain often focus on interventions that relieve pain, and assessing and treating sleep disturbance are secondary or not addressed. This article reviews the literature on pain and co-occurring sleep disturbance, describes the assessment of sleep disturbance, and outlines nonpharmacologic and pharmacologic treatment strategies to improve sleep in patients with chronic pain.

Full Text Available Abstract Background Chronic pain conditions are characterized by significant individual variability complicating the identification of pathophysiological markers. Leukocyte telomere length (TL, a measure of cellular aging, is associated with age-related disease onset, psychosocial stress, and health-related functional decline. Psychosocial stress has been associated with the onset of chronic pain and chronic pain is experienced as a physical and psychosocial stressor. However, the utility of TL as a biological marker reflecting the burden of chronic pain and psychosocial stress has not yet been explored. Findings The relationship between chronic pain, stress, and TL was analyzed in 36 ethnically diverse, older adults, half of whom reported no chronic pain and the other half had chronic knee osteoarthritis (OA pain. Subjects completed a physical exam, radiographs, health history, and psychosocial questionnaires. Blood samples were collected and TL was measured by quantitative polymerase chain reaction (qPCR. Four groups were identified characterized by pain status and the Perceived Stress Scale scores: 1 no pain/low stress, 2 no pain/high stress, chronic pain/low stress, and 4 chronic pain/high stress. TL differed between the pain/stress groups (p = 0.01, controlling for relevant covariates. Specifically, the chronic pain/high stress group had significantly shorter TL compared to the no pain/low stress group. Age was negatively correlated with TL, particularly in the chronic pain/high stress group (p = 0.03. Conclusions Although preliminary in nature and based on a modest sample size, these findings indicate that cellular aging may be more pronounced in older adults experiencing high levels of perceived stress and chronic pain.
Full Text Available Objectives: The aim of this study is to investigate low back pain of housewives and to deteremine relationships between psychological status, education and physical health in housewives.Materials and methods: Thirty premenopausal housewives aged 33-45 years with chronic low back pain were included and the control group consisted of 30 healthy premenopausal housewives. Physical examinations were performed. Age, height, weight, educational level, number of children, consumption of cigarettes and alcohol were recorded. The body mass index (BDI was measured. The severity of back pain was measured by the Oswestry Disability Index (ODI, psychological status was evaluated by the Beck Depression Inventory (BDI and muscle strength by manual technique.Results: There was no difference between demographic data of patients and controls. BDI scores of patients were significantly higher than the controls (p<0,01. Abdominal and dorsal muscle strength were higher in the control group but different was not significant. OBAS values in the patient group, were positively correlated with BDI and BMI (p= 0.011; p= 0.001, respectively, and negatively correlated with abdominal and dorsal muscle strength (p= 0.006 and p= 0.001. Significant correlations were found between abdominal and dorsal muscle strength and the BMI, ODI and BDI scores and high educational level positively affected the ODI and the BDI scores in patients.Conclusion: The housewives with chronic back pain and do not exercise regularly limit activities of daily living. Because of higher BDI scores of patients with chronic low back pain, these patients should also undergo psychiatric examination. J Clin Exp Invest 2011; 2 (3: 295-298.

Chronic pain conditions are the top reason patients seek care, the most common reason for disability and addiction, and the biggest driver of healthcare costs; their treatment costs more than cancer, heart disease, dementia, and diabetes care. The personal impact in terms of suffering, disability, depression, suicide, and other problems is incalculable. There has been much effort to prevent many medical and dental conditions, but little effort has been directed toward preventing chronic pain. To address this deficit, a massive open online course (MOOC) was developed for students and healthcare professionals. “Preventing Chronic Pain: A Human Systems Approach” was offered by the University of Minnesota through the online platform Coursera. The first offering of this free open course was in the spring of 2014 and had 23 650 participants; 53% were patients or consumers interested in pain. This article describes the course concepts in preventing chronic pain, the analytic data from course participants, and postcourse evaluation forms. PMID:26421231

Musculoskeletal conditions are the most frequent cause of chronic pain and affect around 1 in 5 adults in Europe. When chronic pain occurs, it becomes disease itself, with substantial clinical, social and economic impact. Effi cacy and tolerability problems are encountered with all therapeutic strategies available to treat musculoskeletal pain. This often limits effective analgesia and patients’ long term compliance, with the result that chronic pain is persistently underestimated and undertr...

Chronic low back pain is a significant public health problem and, although underused, yoga may be an effective complementary treatment. The current study examined associations of pain catastrophizing and fear of movement with attitudes toward yoga in adults with chronic low back pain. Participants completed three quantitative questionnaires assessing specific constructs: beliefs about yoga, fear of movement, and pain catastrophizing. A semi-structured in-person interview was then conducted to obtain specific pain-related information. Hierarchical regression and mediational analyses were used to test hypotheses. Consistent with the fear-avoidance model of chronic pain, catastrophizing and fear of movement were negatively associated with yoga attitudes. Specifically, fear of movement was a mediator between catastrophizing and attitudes toward yoga. Individuals with higher levels of catastrophizing and fear of movement may be less likely to consider a pain treatment involving physical movement. PMID:26256134

Pain commonly affects multiple sclerosis (MS) patients, and has the potential to become chronic and burden an already damaged central nervous system. Imaging studies are providing insights into brain restructuring associated with chronic pain and different chronic pain conditions seem to evoke distinct plasticity patterns. Our objective was to study the structural and functional brain changes of chronic neuropathic pain of MS. Employing structural and resting functional magnetic resonance imaging we compared MS patients with chronic central pain with MS patients without pain matched with respect to age, gender, subtype and duration of MS and disability. Mean duration of pain was 7.6 years. Comparing the pain and no-pain groups, brain functional default-mode network differences were found. There was decreased coactivation in the caudate nucleus and nucleus accumbens bilaterally. Also, for the relapsing-remitting subgroup of patients, grey matter thickness changes predominated in the pain group in the mesial region of the temporal lobes, caudate, putamen, thalami and the fronto-parietal cortex; in the group without pain, changes predominated in the frontopolar and orbitofrontal cortices and in the occipital areas. A dysfunction in the reward system in chronic pain of MS was found, particularly in the brain areas involved in its motivational aspects, as such probably reflecting the maladaptive physiology of chronic pain, and possibly the signature of pain in MS, in a disease where reward impairment seems to be already one of its features.

Chronic pancreatitis(CP) is a chronic inflammatory disease of the pancreas. The main symptom of patients with CP is chronic and severe abdominal pain. However, the pathophysiology of pain in CP remains obscure.Traditionally, researchers believed that the pain was caused by anatomical changes in pancreatic structure. However, treatment outcomes based on such beliefs are considered unsatisfactory. The emerging explanations of pain in CP are trending toward neurobiological theories. This article aims to review current evidence regarding the neuropathophysiology of pain in CP and its potential implications for the development of new treatments for pain in CP.
Full Text Available Abstract Animal models of chronic pain are widely used to investigate basic mechanisms of chronic pain and to evaluate potential novel drugs for treating chronic pain. Among the different criteria used to measure chronic pain, behavioral responses are commonly used as the end point measurements. However, not all chronic pain conditions can be easily measured by behavioral responses such as the headache, phantom pain and pain related to spinal cord injury. Here I propose that cortical indexes, that indicate neuronal plastic changes in pain-related cortical areas, can be used as endpoint measurements for chronic pain. Such cortical indexes are not only useful for those chronic pain conditions where a suitable animal model is lacking, but also serve as additional screening methods for potential drugs to treat chronic pain in humans. These cortical indexes are activity-dependent immediate early genes, electrophysiological identified plastic changes and biochemical assays of signaling proteins. It can be used to evaluate novel analgesic compounds that may act at peripheral or spinal sites. I hope that these new cortical endpoint measurements will facilitate our search for new, and more effective, pain medicines, and help to reduce false lead drug targets.

There is increasing evidence that pain-related fear influences the development and maintenance of pain disability, presumably mediated through the fear-related avoidance of valued activities. Individually tailored graded exposure in vivo (GEXP) has been demonstrated to reduce pain-related fear and increase functional abilities in patients with chronic low back pain, neck pain, and complex regional pain syndrome. The current study aimed to test whether these effects generalize towards patients with work-related upper extremity pain. A sequential replicated and randomized single-case experimental phase design with multiple measurements was used. Within each participant, GEXP was compared to a no-treatment baseline period and a no-treatment 6-month follow-up period. Eight patients who reported a high level of pain-related fear were included in the study. Daily changes in pain catastrophizing, pain-related fear, and pain intensity were assessed using a diary, and subjected to randomization tests. Before the start of the baseline period, just after GEXP, and at 6-month follow-up, clinically relevant changes of pain catastrophizing, pain-related fear, perceived harmfulness of physical activity, pain disability, and participation/autonomy were verified. When GEXP was introduced, levels of pain catastrophizing and pain-related fear decreased significantly. Clinically relevant improvements were observed for pain disability, perceived participation, and autonomy. These favourable changes were maintained until 6-month follow-up. The findings of the current study underscore the external validity of a cognitive-behavioural GEXP treatment for patients with chronic pain reporting increased pain-related fear.

Chronic musculoskeletal pain is one of the most intractable clinical problems faced by clinicians and can be devastating for patients. Central pain amplification is perceived pain that cannot be fully explained on the basis of somatic or neuropathic processes and is due to physiologic alterations in pain transmission or descending pain modulatory pathways. In any individual, central pain amplification may complicate nociceptive or neuropathic pain. Furthermore, patients with somatic symptom disorders may have alterations in their psychological or behavioral responses to pain that contribute significantly to the clinical presentation. Genetic, physiologic, and psychological factors associated with central pain amplification are beginning to be understood. One important contributor to chronic pain is perceived stress and stress response systems. We and others have shown a complex relationship between the physiologic stress response and chronic pain symptoms. Unfortunately, treatments for chronic pain are woefully inadequate and often worsen clinical outcomes. Developing new treatment strategies for patients with chronic pain is of utmost urgency. This essay provides a framework for thinking about chronic pain and developing new treatment approaches. PMID:26330672

Pain behaviors are shaped by social demands and learning processes, and chronic pain has been previously suggested to affect their meaning. In this study, we combined functional magnetic resonance imaging with in-scanner video recording during thermal pain stimulations and use multilevel mediation analyses to study the brain mediators of pain facial expressions and the perception of pain intensity (self-reports) in healthy individuals and patients with chronic back pain (CBP). Behavioral data showed that the relation between pain expression and pain report was disrupted in CBP. In both patients with CBP and healthy controls, brain activity varying on a trial-by-trial basis with pain facial expressions was mainly located in the primary motor cortex and completely dissociated from the pattern of brain activity varying with pain intensity ratings. Stronger activity was observed in CBP specifically during pain facial expressions in several nonmotor brain regions such as the medial prefrontal cortex, the precuneus, and the medial temporal lobe. In sharp contrast, no moderating effect of chronic pain was observed on brain activity associated with pain intensity ratings. Our results demonstrate that pain facial expressions and pain intensity ratings reflect different aspects of pain processing and support psychosocial models of pain suggesting that distinctive mechanisms are involved in the regulation of pain behaviors in chronic pain.

Chronic back pain is a major source of disability, decreased quality of life and healthcare costs. Treating chronic back pain is difficult, with even effective therapies only being modestly effective. Helping patients avoid the transition from acute to chronic low back pain is a promising strategy for preventing suffering and reducing healthcare utilization. The biopsychosocial model provides a useful framework for understanding factors that contribute to chronicity in low back pain, and are important targets for interventions. This article reviews recent research on predictors of chronicity and treatment strategies in higher risk patients that may be helpful for preventing chronicity. PMID:24654586

Gait is an important indicator of health. Chronic lower body pain may impair gait and lead to morbidity and mortality. We investigated the associations between lower body pain and gait in community-dwelling individuals, independent from osteoarthritis (OA). This population based cohort study included 2304 Rotterdam Study participants who underwent electronic walkway gait assessment. Thirty different variables resulting from gait assessment were summarized into seven gait domains using principle components analysis: i.e. Rhythm, Variability, Phases, Pace, Tandem, Turning, and Base of Support. Chronic lower body pain was assessed using pain drawings. OA was defined as a Kellgren & Lawrence score of 2 or higher on radiographs of the hip and/or knee. Linear regression analysis was used to study associations. Participants with chronic pain in the leg and hip, had lower Rhythm, Phases, and Pace, independent from OA. Additionally, we found unilateral pain to associate with larger gait asymmetry. No associations were found between chronic pain and the other gait domains, including gait variability. However, within individuals with hip pain, gait variability was higher in individuals with radiographic OA compared to those without OA. This is the first population based study showing chronic lower body pain associates with gait differences independent from OA. Participants with pain were found to walk with slower and smaller steps, longer double support and more asymmetry. Proper care and treatment of chronic pain could be a way of reducing gait problems and thereby fall risk and associated mortality. In addition, gait assessment may help identifying individuals with OA from those having pain due to other causes.

Full Text Available OBJECTIVE To estimate worldwide prevalence of chronic low back pain according to age and sex.METHODS We consulted Medline (PubMed, LILACS and EMBASE electronic databases. The search strategy used the following descriptors and combinations: back pain, prevalence, musculoskeletal diseases, chronic musculoskeletal pain, rheumatic, low back pain, musculoskeletal disorders and chronic low back pain. We selected cross-sectional population-based or cohort studies that assessed chronic low back pain as an outcome. We also assessed the quality of the selected studies as well as the chronic low back pain prevalence according to age and sex.RESULTS The review included 28 studies. Based on our qualitative evaluation, around one third of the studies had low scores, mainly due to high non-response rates. Chronic low back pain prevalence was 4.2% in individuals aged between 24 and 39 years old and 19.6% in those aged between 20 and 59. Of nine studies with individuals aged 18 and above, six reported chronic low back pain between 3.9% and 10.2% and three, prevalence between 13.1% and 20.3%. In the Brazilian older population, chronic low back pain prevalence was 25.4%.CONCLUSIONS Chronic low back pain prevalence increases linearly from the third decade of life on, until the 60 years of age, being more prevalent in women. Methodological approaches aiming to reduce high heterogeneity in case definitions of chronic low back pain are essential to consistency and comparative analysis between studies. A standard chronic low back pain definition should include the precise description of the anatomical area, pain duration and limitation level.

Chronic pain in children and adolescents can be difficult for a single provider to manage in a busy clinical setting. Part of this difficulty is that pediatric chronic pain not only impacts the child but also the families of these children. In this review article, we discuss etiology and pathophysiology of chronic pain, along with variables that impact the severity of chronic pain and functional loss. We review diagnosis and management of selected chronic pain conditions in pediatric patients, including headache, low back pain, hypermobility, chronic fatigue, postural orthostatic tachycardia syndrome, abdominal pain, fibromyalgia, and complex regional pain syndrome. For each condition, we create a road map that contains therapy prescriptions, exercise recommendations, and variables that may influence pain severity. Potential medications for these pain conditions and associated symptoms are reviewed. A multidisciplinary approach for managing children with these conditions, including pediatric pain rehabilitation programs, is emphasized. Lastly, we discuss psychological factors and interventions for pediatric chronic pain and potential complementary and alternative natural products and interventions. PMID:26568508

A qualitative study explored the challenges and needs of children living with parental chronic pain. Young adult children (n=30) of parents with chronic pain were interviewed. Parents (n=20) with chronic pain participated in four focus groups. Content analysis yielded five categories of child challenges: (a) understanding the big picture; (b) enduring hardships; (c) grieving losses; (d) communicating with parent, and; (e) isolating self from peers. Three categories of child needs emerged: (a) knowledge; (b) skills, and; (c) supervised interaction. Understanding these challenges and needs is a vital step in the process of developing evidence-based interventions for this at-risk group. PMID:25557986

The present study investigated the analgesic effect of a novel synthetic cyclohexanone derivative, 2,6-bis-4-(hydroxyl-3-methoxybenzilidine)-cyclohexanone or BHMC in a mouse model of chronic constriction injury-induced neuropathic pain. It was demonstrated that intraperitoneal administration of BHMC (0.03, 0.1, 0.3 and 1.0mg/kg) exhibited dose-dependent inhibition of chronic constriction injury-induced neuropathic pain in mice, when evaluated using Randall-Selitto mechanical analgesiometer. It was also demonstrated that pretreatment of naloxone (non-selective opioid receptor blocker), nor-binaltorphimine (nor-BNI, selective κ-opioid receptor blocker), but not β-funaltrexamine (β-FN, selective μ-opioid receptor blocker) and naltrindole hydrochloride (NTI, selective δ-opioid receptor blocker), reversed the anti-nociceptive effect of BHMC. In addition, the analgesic effect of BHMC was also reverted by pretreatment of 1H-[1,2,4]Oxadiazole[4,3-a]quinoxalin-1-one (ODQ, soluble guanosyl cyclase blocker) and glibenclamide (ATP-sensitive potassium channel blocker) but not Nω-nitro-l-arginine (l-NAME, a nitric oxide synthase blocker). Taken together, the present study demonstrated that the systemic administration of BHMC attenuated chronic constriction, injury-induced neuropathic pain. We also suggested that the possible mechanisms include κ-opioid receptor activation and nitric oxide-independent cyclic guanosine monophosphate activation of ATP-sensitive potassium channel opening.

Psychological trauma is associated with an increased risk for chronification of nonspecific chronic back pain (nsCLBP) independent of posttraumatic stress disorder (PTSD). However, the mechanisms underlying the role of psychological trauma in nsCLBP are less clear than in PTSD. Therefore, this study considered whether psychological trauma exposure (TE) is accompanied by specific alterations in pain perception. The study included 56 participants with nsCLBP and TE (nsCLBP-TE), 93 participants with nsCLBP without TE (nsCLBP-W-TE), and 31 pain-free controls. All participants underwent a thorough clinical evaluation. The standardized quantitative sensory testing protocol of the "German Research Network on Neuropathic Pain" was used to obtain comprehensive profiles on somatosensory functions in painful (back) and non-painful areas (hand). The protocol consisted of thermal and mechanical detection as well as pain thresholds, vibration thresholds, and pain sensitivity to sharp and blunt mechanical stimuli. Psychological trauma was validated by structured clinical interview. Trauma-associated symptom severity, anxiety, and depressive symptomatology were assessed by self-report questionnaires. Differences in somatosensory function were seen only for pressure pain thresholds. Compared with controls, nsCLBP-TE revealed hyperalgesia generalized in space with lower thresholds in painful and non-painful areas, whereas nsCLBP-W-TE demonstrated localized alterations with decreased thresholds only in the pain-affected area of the back (P ≤ 0.006). Our findings suggest an augmented central pain processing in nsCLBP-TE (alterations in painful and non-painful areas), whereas nsCLBP-W-TE show only local changes (alterations only in the painful area) suggesting regional sensitization processes. This finding might explain why TE without PTSD is associated with an increased prevalence of chronic pain. PMID:25790450

Attentional biases reflect an individual's selective attention to salient stimuli within their environment, for example an experience of back pain. Eysenck suggests that different personality types show different attentional biases to threatening information. This study is the first to test Eysenck's theory within a chronic back pain population by investigating the attentional biases of four different personality types using a back pain specific dot-probe paradigm. Participants were 70 volunt...

Pain is common as a presenting complaint to outpatient and emergency departments for children, yet pain management represents one of the children's largest unmet needs. A child may present with acute pain for an intermittent issue or may have acute or chronic pain in the setting of chronic illness. The mainstay of treatment for pain uses a stepwise approach for pain management, such as set up by the World Health Organization. For children with life-limiting illnesses, the Institute of Medicine guidelines recommends referral upon diagnosis for palliative care, meaning that the child receives comprehensive services that include pain control in coordination with curative therapies; yet barriers remain. From the provider perspective, pain can be better addressed through a careful assessment of one's own knowledge, skills, and attitudes. The key components of pain management in children are multimodal, regardless of the cause of the pain. PMID:23329083

Full Text Available BACKGROUND: Chronicity of pain is one of the most interesting questions in chronic pain study. Clinical and experimental data suggest that supraspinal areas responsible for negative emotions such as depression and anxiety contribute to the chronicity of pain. The amygdala is suspected to be a potential structure for the pain chronicity due to its critical role in processing negative emotions and pain information. OBJECTIVE: This study aimed to investigate whether amygdala or its subregions, the basolateral amygdala (BLA and the central medial amygdala (CeA, contributes to the pain chronicity in the spared nerve injury (SNI-induced neuropathic pain model of rats. METHODOLOGY/PRINCIPAL FINDINGS: (1 Before the establishment of the SNI-induced neuropathic pain model of rats, lesion of the amygdaloid complex with stereotaxic injection of ibotenic acid (IBO alleviated mechanical allodynia significantly at days 7 and 14, even no mechanical allodynia at day 28 after SNI; Lesion of the BLA, but not the CeA had similar effects; (2 however, 7 days after SNI when the neuropathic pain model was established, lesion of the amygdala complex or the BLA or the CeA, mechanical allodynia was not affected. CONCLUSION: These results suggest that BLA activities in the early stage after nerve injury might be crucial to the development of pain chronicity, and amygdala-related negative emotions and pain-related memories could promote pain chronicity.

Aim: To evaluate the efficacy of biofeedback therapy in patients with chronic pelvic pain syndrome(CPPS). Methods: From November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI)and classified by the NIH classification standard. Sixty-two patients of CPPS category Ⅲ were involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid +-+++ and bacterial culture negative. Their NIH-CPSI were 12-40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA-23 mA and duration of 20 minutes. Results: Sixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2-3treatment courses and other symptoms disappeared after 4-5 courses. Conclusion: Biofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.

Chronic pelvic pain in women is a key site through which explorations of the meanings of female gender and pain might further insights into the broader question of the embodied experience of women in relation to pain. A biocultural approach is used to present an analysis of interviews with 40 New Zealand women in which they reflect on 'how come' they have chronic pelvic pain. Women consistently employ a mechanistic rendition of medical discourse and understandings in their constructions of 'how come' they have pain, accompanied by a reiteration of 'not knowing' and a normalizing of their pelvic pain. We explore how this normalizing works within the narratives to establish women's pelvic pain as intrinsically gendered. Etiological meanings that are constructed in medical terms and yet are unable to be interpreted within a dualist frame of normality and pathology, we argue, permeate and shape gendered experience of chronic pain conditions.

Chronic pain is associated with significant costs to individuals directly affected by this condition, their families, the healthcare system, and the society as a whole. This paper investigates the relationship between chronic pain and life satisfaction using a sample of around 90,000 observations from the first ten waves of the Household, Income and Labour Dynamics of Australia Survey (HILDA), which is a representative survey of the Australian population that started in 2000. We estimate the negative impact on life satisfaction and examine the persistence of the effect over multiple years. Chronic pain is associated with poor health conditions, disability, decreased participation in the labour market and lower quality of life. We calculate the compensating income variation of chronic pain, based on the measurement of chronic pain, the life satisfaction of individuals and the income of households. Panel data models with random and fixed effects are used to control for characteristics of individuals that do not vary over time. Further, we investigate whether individuals who experience chronic pain exhibit adaptation and recovery in life satisfaction after 3 years. Overall, we find that chronic pain has a large negative association with life satisfaction, and that the compensating income variation is substantial (around 640 US$ per day).

Full Text Available Abstract Background This cross validation study examined the reliability of the Multidimensional Pain Inventory (MPI and the stability of the Multidimensional Pain Inventory Classification System of the empirically derived subgroup classification obtained by cluster analysis in chronic musculoskeletal pain. Reliability of the German Multidimensional Pain Inventory was only examined once in the past in a small sample. Previous international studies mainly involving fibromyalgia patients showed that retest resulted in 33–38% of patients being assigned to a different Multidimensional Pain Inventory subgroup classification. Methods Participants were 204 persons with chronic musculoskeletal pain (82% chronic non-specific back pain. Subgroup classification was conducted by cluster analysis at 4 weeks before entry (=test and at entry into the pain management program (=retest using Multidimensional Pain Inventory scale scores. No therapeutic interventions in this period were conducted. Reliability was quantified by intraclass correlation coefficients (ICC and stability by kappa coefficients (κ. Results Reliability of the Multidimensional Pain Inventory scales was least with ICC = 0.57 for the scale life control and further ranged from ICC = 0.72 (negative mood to 0.87 (solicitous responses in the other scales. At retest, 82% of the patients in the Multidimensional Pain Inventory cluster interpersonally distressed (κ = 0.69, 80% of the adaptive copers (κ = 0.58, and 75% of the dysfunctional patients (κ = 0.70 did not change classification. In total, 22% of the patients changed Multidimensional Pain Inventory cluster group, mainly into the adaptive copers subgroup. Conclusion Test-retest reliability of the German Multidimensional Pain Inventory was moderate to good and comparable to other language versions. Multidimensional Pain Inventory subgroup classification is substantially stable in chronic back pain patients when compared

Full Text Available Extensive training of repetitive and highly skilled movements, as it occurs in professional classical musicians, may lead to changes in tactile sensitivity and corresponding cortical reorganization of somatosensory cortices. It is also known that professional musicians frequently experience musculoskeletal pain and pain-related symptoms during their careers. The present study aimed at understanding the complex interaction between chronic pain and music training with respect to somatosensory processing. For this purpose, tactile thresholds (mechanical detection, grating orientation, two-point discrimination and subjective ratings to thermal and pressure pain stimuli were assessed in 17 professional musicians with chronic pain, 30 pain-free musicians, 20 non-musicians with chronic pain, and 18 pain-free non-musicians. We found that pain-free musicians displayed greater touch sensitivity (i.e. lower mechanical detection thresholds, lower tactile spatial acuity (i.e., higher grating orientation thresholds and increased pain sensitivity to pressure and heat compared to pain-free non-musicians. Moreover, we also found that musicians and non-musicians with chronic pain presented lower tactile spatial acuity and increased pain sensitivity to pressure and heat compared to pain-free non-musicians. The significant increment of pain sensitivity together with decreased spatial discrimination in pain-free musicians and the similarity of results found in chronic pain patients, suggests that the extensive training of repetitive and highly skilled movements in classical musicians could be considered as a risk factor for developing chronic pain, probably due to use-dependent plastic changes elicited in somatosensory pathways.
Full Text Available Chronic pain is one of the most prevalent health problems in the world today, yet neurological markers, critical to diagnosis of chronic pain, are still largely unknown. The ability to objectively identify individuals with chronic pain using functional magnetic resonance imaging (fMRI data is important for the advancement of diagnosis, treatment, and theoretical knowledge of brain processes associated with chronic pain. The purpose of our research is to investigate specific neurological markers that could be used to diagnose individuals experiencing chronic pain by using multivariate pattern analysis with fMRI data. We hypothesize that individuals with chronic pain have different patterns of brain activity in response to induced pain. This pattern can be used to classify the presence or absence of chronic pain. The fMRI experiment consisted of alternating 14 seconds of painful electric stimulation (applied to the lower back with 14 seconds of rest. We analyzed contrast fMRI images in stimulation versus rest in pain-related brain regions to distinguish between the groups of participants: 1 chronic pain and 2 normal controls. We employed supervised machine learning techniques, specifically sparse logistic regression, to train a classifier based on these contrast images using a leave-one-out cross-validation procedure. We correctly classified 92.3% of the chronic pain group (N = 13 and 92.3% of the normal control group (N = 13 by recognizing multivariate patterns of activity in the somatosensory and inferior parietal cortex. This technique demonstrates that differences in the pattern of brain activity to induced pain can be used as a neurological marker to distinguish between individuals with and without chronic pain. Medical, legal and business professionals have recognized the importance of this research topic and of developing objective measures of chronic pain. This method of data analysis was very successful in correctly classifying

Studies which specifically manipulate catastrophizing are necessary to establish causation. The present study enrolled 100 healthy individuals. Participants were randomly assigned to repeat a positive, neutral, or one of three catastrophizing statements during a cold pressor task (CPT. Outcome measures of pain tolerance and pain intensity were recorded. No change was noted in catastrophizing immediately following the CPT (F(1,84 = 0.10, p = 0.75, partial η2 < 0.01 independent of group assignment (F(4,84 = 0.78, p = 0.54, partial η2 = 0.04. Pain tolerance (F(4 = 0.67, p = 0.62, partial η2 = 0.03 and pain intensity (F(4 = 0.73, p = 0.58, partial η2 = 0.03 did not differ by group. This study suggests catastrophizing may be difficult to manipulate through experimental pain procedures and repetition of specific catastrophizing statements was not sufficient to change levels of catastrophizing. Additionally, pain tolerance and pain intensity did not differ by group assignment. This study has implications for future studies attempting to experimentally manipulate pain catastrophizing.Keywords: pain, catastrophizing, experimental, cold pressor task, pain catastrophizing scale
Chronic pain is a significant health problem that greatly impacts the quality of life of individuals and imparts high costs to society. Despite intense research effort in understanding of the mechanism of pain, chronic pain remains a clinical problem that has few effective therapies. The advent of human brain imaging research in recent years has changed the way that chronic pain is viewed. To further extend the use of human brain imaging techniques for better therapies, the adoption of imaging technique onto the animal pain models is essential, in which underlying brain mechanisms can be systematically studied using various combination of imaging and invasive techniques. The general goal of this thesis is to addresses how brain develops and maintains chronic pain in an animal model using fMRI. We demonstrate that nucleus accumbens, the central component of mesolimbic circuitry, is essential in development of chronic pain. To advance our imaging technique, we develop an innovative methodology to carry out fMRI in awake, conscious rat. Using this cutting-edge technique, we show that allodynia is assoicated with shift brain response toward neural circuits associated nucleus accumbens and prefrontal cortex that regulate affective and cognitive component of pain. Taken together, this thesis provides a deeper understanding of how brain mediates pain. It builds on the existing body of knowledge through maximizing the depth of insight into brain imaging of chronic pain.

There is increasing interest in the use of complimentary and alternative medicine (CAM) for the treatment of chronic pain. This review examines alternative and complimentary therapies, which can be incorporated as part of a biopsychosocial approach in the treatment of chronic pain syndromes. In the present investigation, literature from articles indexed on PubMed was evaluated including topics of alternative therapies, complimentary therapies, pain psychology, biofeedback therapy, physical exercise therapies, acupuncture, natural and herbal supplements, whole-body cryotherapy, and smartphone technologies in the treatment of chronic pain syndromes. This review highlights the key role of psychology in the treatment of chronic pain. Cognitive behavior therapy appears to be the most impactful while biofeedback therapy has also been shown to be effective for chronic pain. Exercise therapy has been shown to be effective in short-, intermediate-, and long-term pain states. When compared to that in sham controls, acupuncture has shown some benefit for neck pain immediately after the procedure and in the short term and improvement has also been demonstrated in the treatment of headaches. The role of smartphones and whole-body cryotherapy are new modalities and further studies are needed. Recent literature suggests that several alternate therapies could play a role in the treatment of chronic pain, supporting the biopsychosocial model in the treatment of pain states. PMID:27038968

The purpose of this study was to investigate the use and perceived benefit of complimentary and alternative medicine (CAM) and physiotherapy treatments tried by people with chronic fatigue syndrome (CFS) to ease painful symptoms. This study used a descriptive, cross-sectional design. People with CFS who experienced pain were recruited to this study. Participants were asked during a semistructured interview about the treatments they had tried to relieve their pain. Each interview was conducted in the home of the participant. Fifty participants were recruited, of which, 10 participants were severely disabled by CFS. Eighteen participants were trying different forms of CAM treatment for pain relief at the time of assessment. Three participants were currently receiving physiotherapy. Throughout the duration of their illness 45 participants reported trying 19 different CAM treatments in the search for pain relief. Acupuncture was reported to provide the most pain relief (n=16). Twenty-seven participants reported a total of 16 different interventions prescribed by their physiotherapist. The results of this study suggest some physiotherapy and CAM treatments may help people manage painful CFS symptoms. Future research should be directed to evaluating the effectiveness of interventions such as acupuncture or gentle soft tissue therapies to reduce pain in people with CFS.

Non-specific chronic low back pain is an occupational hazard for nurses. It may result in persistent and disabling pain for some people. There are many techniques for investigating, assessing and treating chronic low back pain. However, research to support some of these interventions and the assumptions that underlie them is limited. Interventions that may be beneficial are not always available to those who need them. Changes to service provision are required to rectify this situation and provide effective treatment for patients with non-specific chronic low back pain. PMID:27097211

Based on theoretical considerations and recent observations, we argue that continued suffering of chronic pain is critically dependent on the state of motivational and emotional mesolimbic-prefrontal circuitry of the brain. The plastic changes that occur within this circuitry in relation to nociceptive inputs dictate the transition to chronic pain, rendering the pain less somatic and more affective in nature. This theoretical construct is a strong departure from the traditional scientific view of pain, which has focused on encoding and representation of nociceptive signals. We argue that the definition of chronic pain can be recast, within the associative learning and valuation concept, as an inability to extinguish the associated memory trace, implying that supraspinal/cortical manipulations may be a more fruitful venue for adequately modulating suffering and related behavior for chronic pain. We briefly review the evidence generated to date for the proposed model and emphasize that the details of underlying mechanisms remain to be expounded.

African American grandparent caregiving is increasing, and evidence shows that grandparent caregiving influences health and its management. As older adults age, their potential of experiencing chronic pain increases, and this is profound given that physiological research shows that African Americans, aside from aging, may have a predisposition for developing chronic pain. Research shows older African Americans experience significant chronic pain, but few have discussed the implications of managing chronic pain in older African Americans who have added parental responsibility. Many older African Americans receive home healthcare services and there is a unique role for home healthcare clinicians in caring for this vulnerable population. This article discusses the impact of pain on caregiving, challenges in pain management, and practice and policy implications to assist home healthcare clinicians maintain the safety and protection of both the older grandparent and grandchildren.

Noonan syndrome (NS) is a multiple malformation syndrome characterized by pulmonic stenosis, cardiomyopathy, short stature, lymphatic dysplasia, craniofacial anomalies, cryptorchidism, clotting disorders, and learning disabilities. Eight genes in the RAS/MAPK signaling pathway are implicated in NS. Chronic pain is an uncommon feature. To investigate the prevalence of pain in NS, we distributed a two-part questionnaire about pain among NS individuals at the Third International Meeting on Genetic Syndromes of the Ras/MAPK Pathway. The first part of the questionnaire queried demographic information among all NS participants. The second part was completed by individuals with chronic pain. Questions included musculoskeletal problems and clinical features of pain. Forty-five questionnaires were analyzed; 53% of subjects were female. Mean age was 17 (2-48) years; 47% had a PTPN11 mutation. Sixty-two percent (28/45) of individuals with NS experienced chronic pain. There was a significant relationship between prevalence of pain and residing in a cold climate (P = 0.004). Pain occurred commonly in extremities/joints and head/trunk, but more commonly in extremities/joints (P = 0.066). Subjects with hypermobile joints were more likely to have pain (P = 0.052). Human growth hormone treatment was not statistically significant among subjects without chronic pain (P = 0.607). We conclude that pain is a frequent and under-recognized clinical feature of NS. Chronic pain may be associated with joint hypermobility and aggravated by colder climate. Our study is a preliminary investigation that should raise awareness about pain as a common symptom in children and adults with NS. PMID:26297936

This case report evaluates virtual reality hypnosis (VRH) in treating chronic neuropathic pain in a patient with a 5-year history of failed treatments. The patient participated in a 6-month trial of VRH, and her pain ratings of intensity and unpleasantness dropped on average 36% and 33%, respectively, over the course of 33 sessions. In addition, she reported both no pain and a reduction of pain for an average of 3.86 and 12.21 hours, respectively, after treatment sessions throughout the course of the VRH treatment. These reductions and the duration of treatment effects following VRH treatment were superior to those following a trial of standard hypnosis (non-VR) treatment. However, the pain reductions with VRH did not persist over long periods of time. The findings support the potential of VRH treatment for helping individuals with refractory chronic pain conditions.

Despite high success rates, many TKA patients develop chronic pain in the months and years following surgery, constituting a public health burden. Pain catastrophizing is a construct that reflects anxious preoccupation with pain, inability to inhibit pain-related fears, amplification of the significance of pain vis-à-vis health implications, and a sense of helplessness regarding pain. Recent research suggests that it may be an important risk factor for untoward TKA outcomes. To clarify this impact, we systematically reviewed the literature to date on pain catastrophizing as a prospective predictor of chronic pain following TKA. Methods: We searched MEDLINE, EMBASE, and PsycINFO databases to identify articles related to pain catastrophizing, TKA, risk models, and chronic pain. We reviewed titles and abstracts to identify original research articles that met our specified inclusion criteria. Included articles were then rated for methodological quality. including methodological quality. Due to heterogeneity in follow-up, analyses, and outcomes reported across studies, a quantitative meta-analysis could not be performed.

Given these results and the vital need to treat the comorbidity of the two disorders, a pilot ACT treatment was implemented in individuals with comorbid chronic pain and opioid addiction. This pilot study supported using neurophysiology to characterize treatment effects and revealed that, following ACT, participants with this comorbidity exhibited reductions in brain activation due to painful stimulus and in connectivity at rest.

Psychological factors have an impact on subjective pain experience. The aim of this study was to explore the occurrence of alexithymia and Early Maladaptive Schemas in a sample of 271 first visit chronic pain patients of six pain clinics. The patients completed the study questionnaire consisting of the Toronto Alexithymia Scale-20, the Finnish version of the Young Schema Questionnaire short form-extended, the Beck Depression Inventory-II, and pain variables. Alexithymic patients scored higher on Early Maladaptive Schemas and had more pain intensity, pain disability and depression than nonalexithymic patients. Both alexithymia and depression correlated significantly with most Early Maladaptive Schemas. The co-occurrence of alexithymia, Early Maladaptive Schemas and depression seems to worsen the pain experience. Screening of alexithymia, depression and Early Maladaptive Schemas may help to plan psychological treatment interventions for chronic pain patients. PMID:26040835

Neck pain is the most common musculoskeletal complaint among computer office workers. There are several reports about the coexistence of neck pain and temporomandibular disorders (TMD). However, there are no studies investigating this association in the context of work involving computers. The purpose of this study was to verify the association between TMD and neck pain in computer office workers. Fifty-two female computer workers who were divided into two groups: (i) those with self-reported chronic neck pain and disability (WNP) (n = 26) and (ii) those without self-reported neck pain (WONP) (n = 26), and a control group (CG) consisting of 26 women who did not work with computers participated in this study. Clinical assessments were performed to establish a diagnosis of TMD, and craniocervical mechanical pain was assessed using manual palpation and pressure pain threshold (PPT). The results of this study showed that the WNP group had a higher percentage of participants with TMD than the WONP group (42·30% vs. 23·07%, χ(2) = 5·70, P = 0·02). PPTs in all cervical sites were significantly lower in the groups WNP and WONP compared to the CG. Regression analysis revealed TMD, neck pain and work-related factors to be good predictors of disability (R(2) = 0·93, P workplace conditions. Consequently, this study attempted to emphasise the importance of considering work activity for minimising neck pain-related disability. PMID:26732204
Full Text Available Teresa Paolucci,* Vincenzo Maria Saraceni, Giulia Piccinini* Physical Medicine and Rehabilitation Unit, Azienda Policlinico Umberto I, Rome, Italy *These authors contributed equally to this work Abstract: Osteoporosis (OP is a pathological condition that manifests clinically as pain, fractures, and physical disability, resulting in the loss of independence and the need for long-term care. Chronic pain is a multidimensional experience with sensory, affective, and cognitive aspects. Age can affect each of these dimensions and the pain that is experienced. In OP, chronic pain appears to have sensory characteristics and properties of nociceptive and neuropathic pain. Its evaluation and treatment thus require a holistic approach that focuses on the specific characteristics of this population. Pain management must therefore include pharmacological approaches, physiotherapy interventions, educational measures, and, in rare cases, surgical treatment. Most rehabilitative treatments in the management of patients with OP do not evaluate pain or physical function, and there is no consensus on the effects of rehabilitation therapy on back pain or quality of life in women with OP. Pharmacological treatment of pain in patients with OP is usually insufficient. The management of chronic pain in patients with OP is complicated with regard to its diagnosis, the search for reversible secondary causes, the efficacy and duration of oral bisphosphonates, and the function of calcium and vitamin D. The aim of this review is to discuss the most appropriate solutions in the management of chronic pain in OP. Keywords: physical therapy, exercise, pharmacological treatment, posture and balance

Previous functional magnetic resonance imaging (fMRI) studies in healthy controls (HC) and pain-free migraine patients found activations to pain-related words in brain regions known to be activated while subjects experience pain. The aim of the present study was to identify neural activations induced by pain-related words in a sample of chronic back pain (CBP) patients experiencing current chronic pain compared to HC. In particular, we were interested in how current pain influences brain activations induced by pain-related adjectives. Subjects viewed pain-related, negative, positive, and neutral words; subjects were asked to generate mental images related to these words during fMRI scanning. Brain activation was compared between CBP patients and HC in response to the different word categories and examined in relation to current pain in CBP patients. Pain-related words vs. neutral words activated a network of brain regions including cingulate cortex and insula in subjects and patients. There was stronger activation in medial and dorsolateral prefrontal cortex (DLPFC) and anterior midcingulate cortex in CPB patients than in HC. The magnitude of activation for pain-related vs. negative words showed a negative linear relationship to CBP patients’ current pain. Our findings confirm earlier observations showing that pain-related words activate brain networks similar to noxious stimulation. Importantly, CBP patients show even stronger activation of these structures while merely processing pain-related words. Current pain directly influences on this activation. PMID:27517967

The paper develops a new theory of chronic pain and pain relief by extracorporeal shock wave treatment. Chronic pain without underlying anatomical disorder is looked at as a pathological control function of memory. Conditioned reflexes are considered to be engraved memory traces linking sensory input of afferent signals with motor response of efferent signals. This feature can be described by associative memory functions of the nervous system. Some conditioned reflexes may cause inappropriate or pathological reactions. Consequently, a circulus vitiosus of pain sensation and muscle and/or vessel contraction is generated when pain becomes chronic (pain spiral). The key feature is a dedicated engram responsible for a pathological (painful) reaction. The pain memory may be explained by the concept of a holographic memory model published by several authors. According to this model it is shown how nervous systems may generate and recall memory contents. The paper shows how extracorporeal shock wave treatment may reorganize pathologic memory traces, thus giving cause to real and permanent pain relief. In a generalized manner, the idea of associative memory functions may help in the understanding of conditioning as a learning process and explain extracorporeal shock wave application as an efficient treatment concept for chronic pain. This concept may open the door for new treatment approaches to chronic pain and several other disorders of the nervous system.
Full Text Available Learning to predict pain based on internal or external cues constitutes a fundamental and highly adaptive process aimed at self-protection. Pain-related fear is an essential component of this response, which is formed by associative and instrumental learning processes. In chronic pain, pain-related fear may become maladaptive, drive avoidance behaviors and contribute to symptom chronicity. Pavlovian fear conditioning has proven fruitful to elucidate associative learning and extinction involving aversive stimuli, including pain, but studies in chronic pain remain scarce. Stress demonstrably exerts differential effects on emotional learning and memory processes, but this has not been transferred to pain-related fear. Within this perspective, we propose that stress could contribute to impaired pain-related associative learning and extinction processes and call for interdisciplinary research. Specifically, we suggest to test the hypotheses that (1 extinction-related phenomena inducing a re-activation of maladaptive pain-related fear (e.g., reinstatement, renewal likely occur in everyday life of chronic pain patients and may alter pain processing, impair perceptual discrimination and favour overgeneralization; (2 acute stress prior to or during acquisition of pain-related fear may facilitate the formation and/or consolidation of pain-related fear memories, (3 stress during or after extinction may impair extinction efficacy resulting in greater reinstatement or context-dependent renewal of pain-related fear; and (4 these effects could be amplified by chronic stress due to early adversity and/or psychiatric comorbidity such as depression or anxiety in patients with chronic pain.

Chronic pain substantially impacts patient function and quality of life and is a burden to society at large in terms of increased health care utilization and loss of productivity. As a result, there is an increasing recognition of chronic pain as a public health crisis. However, there remains wide variability in clinical practices related to the prevention, assessment, and treatment of chronic pain. Certain fundamental aspects of chronic pain are often neglected including the contribution of the psychological, social, and contextual factors associated with chronic pain. Also commonly overlooked is the importance of understanding the likely neurobiological mechanism(s) of the presenting pain and how they can guide treatment selection. Finally, physicians may not recognize the value of using electronic medical records to systematically capture data on pain and its impact on mood, function, and sleep. Such data can be used to monitor onset and maintenance of treatments effects at the patient level and evaluate costs at the systems level. In this review we explain how these factors play a critical role in the development of a coordinated, evidence-based treatment approach tailored to meet specific needs of the patient. We also discuss some practical approaches and techniques that can be implemented by clinicians in order to enhance the assessment and management of individuals with chronic pain in primary care settings.

Chronic neck pain attributed to a myofascial pain syndrome is characterized by the presence of muscle contractures referred to as myofascial trigger points. In this randomized, parallel-group, blinded, controlled clinical trial, we examined the effectiveness of deep dry needling (DDN) of myofascial trigger points in people with chronic nonspecific neck pain. The study was conducted at a public Primary Health Care Centre in Madrid, Spain, from January 2010 to December 2014. A total of 130 participants with nonspecific neck pain presenting with active myofascial trigger points in their cervical muscles were included. These participants were randomly allocated to receive: DDN plus stretching (n = 65) or stretching only (control group [n = 65]). Four sessions of treatment were applied over 2 weeks with a 6-month follow-up after treatment. Pain intensity, mechanical hyperalgesia, neck active range of motion, neck muscle strength, and perceived neck disability were measured at baseline, after 2 sessions of intervention, after the intervention period, and 15, 30, 90, and 180 days after the intervention. Significant and clinically relevant differences were found in favour of dry needling in all the outcomes (all P dry needling and passive stretching is more effective than passive stretching alone in people with nonspecific neck pain. The results support the use of DDN in the management of myofascial pain syndrome in people with chronic nonspecific neck pain. PMID:27537209

This study examined whether repression predicts outcome following multidisciplinary treatment for chronic pain and whether links between anxiety and outcome are obscured by repressors. Ninety-three chronic pain patients completed a 4-week pain program. Lifting capacity, walking endurance, depression, pain severity, and activity were measured at pre- and posttreatment. Low-anxious, repressor, high-anxious, and defensive/high-anxious groups were formed from median splits of Anxiety Content (ACS) and Lie scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). Significant ACS x Lie interactions were found for lifting capacity, depression, and pain severity changes. Planned comparisons showed that both repressors and high-anxious patients performed poorly on lifting capacity; repressors alone recovered poorly on depression and pain severity. Results imply that repression may interfere with the process and outcome of pain programs. PMID:10711590

: Over the past two decades, the use of opioids to manage chronic pain has increased substantially, primarily in response to the recognized functional, emotional, and financial burden associated with chronic pain. Within this same period, unintentional death related to prescription opioids has been identified as a public health crisis, owing in part to such factors as insufficient professional training and medication overprescription, misuse, and diversion. The authors discuss current best practices for prescribing opioids for chronic pain, emphasizing patient assessment and essential patient teaching points regarding safe medication use, storage, and disposal.

The management of insomnia in patients experiencing chronic pain requires careful evaluation, good diagnostic skills, familiarity with cognitive-behavioural interventions and a sound knowledge of pharmacological treatments. Sleep disorders are characterised by a circular interrelationship with chronic pain such that pain leads to sleep disorders and sleep disorders increase the perception of pain. Sleep disorders in individuals with chronic pain remain under-reported, under-diagnosed and under-treated, which may lead--together with the individual's emotional, cognitive and behavioural maladaptive responses--to the frequent development of chronic sleep disorders. The moderately positive relationship between pain severity and sleep complaints, and the specificity of pain-related arousal and mediating variables such as depression, illustrate that insomnia in relation to chronic pain is multifaceted and poorly understood. This may explain the limited success of the available treatments. This article discusses the evaluation of patients with chronic pain and insomnia and the available pharmacological and nonpharmacological interventions to manage the sleep disorder. Non-pharmacological interventions should not be considered as single interventions, but in association with one another. Some non-pharmacological interventions especially the cognitive and behavioural approaches, can be easily implemented in general practice (e.g. stimulus control, sleep restriction, imagery training and progressive muscle relaxation). Hypnotics are routinely prescribed in the medically ill, regardless of their adverse effects; however, their long-term efficacy is not supported by robust evidence. Antidepressants provide an interesting alternative to hypnotics, since they can improve pain perception as well as sleep disorders in selected patients. Sedative antipsychotics can be considered for sleep disturbances in those patients exhibiting psychotic features, or for those with
Full Text Available Howard S Smith,1 Eric J Smith,2 Benjamin R Smith21Department of Anesthesiology, Albany Medical College, Albany, NY; 2The Pharmaceutical Research Institute, Albany College of Pharmacy and Health Sciences, Rensselaer, NY, USAAbstract: Chronic musculoskeletal pain is among the most frequent painful complaints that healthcare providers address. The bulk of these complaints are chronic low back pain and chronic osteoarthritis. Osteoarthritis is the most common form of arthritis in the United States. It is a chronic degenerative disorder characterized by a loss of cartilage, and occurs most often in older persons. The management of osteoarthritis and chronic low back pain may involve both nonpharmacologic (eg, weight loss, resistive and aerobic exercise, patient education, cognitive behavioral therapy and pharmacologic approaches. Older adults with severe osteoarthritis pain are more likely to take analgesics than those with less severe pain. The pharmacologic approaches to painful osteoarthritis remain controversial, but may include topical as well as oral nonsteroidal antiinflammatory drugs, acetaminophen, duloxetine, and opioids. The role of duloxetine for musculoskeletal conditions is still evolving.Keywords: pain, musculoskeletal, duloxetine, osteoarthritis, low back, serotonin-norepinephrine reuptake inhibitor

Full Text Available Because of the great prevalence of chronic pain, it is not surprising that there have been a number of influential reports by the Institute of Medicine, National Institutes of Health, and the World Health Organization that have documented the medical, social and economic problems caused by it, and the need for better pain-management programs. The present article briefly reviews these reports, and then focuses on three important areas that need to be considered when addressing the continuing and growing epidemic of one of the most prevalent types of chronic pain [chronic low back pain (CLBP]: the biopsychosocial model of chronic pain; the paradigm shift in medicine from a disease model to an illness model of CLBP; and a review of the treatment- and cost-effectiveness of interdisciplinary chronic pain management programs. This overview will serve as an important prelude to other topics related to low back pain included in this Special Issue of Healthcare. Topics covered will range from assessment and treatment approaches, to important psychosocial mediators/moderators such as coping and pain beliefs.

Background. Patients diagnosed with chronic pain (CP) and rheumatoid arthritis (RA) represent two samples with overlapping symptoms, such as experiencing significant pain. Objectives. To compare the level of psychological distress among patients diagnosed CP attending a specialist pain clinic with those attending a specialist RA clinic. Measures. A cross-sectional study was conducted at an academic specialist chronic pain and rheumatology clinic. Participants. 330 participants included a CP group (n = 167) and a RA group (n = 163) completed a booklet of questionnaires regarding demographic characteristics, duration, and severity of their pain. Psychological and personality variables were compared between the CP and RA participants using a Multivariate Analysis of Covariance (MANCOVA). Results. Level of psychological distress based on the subscales of the DASS (depression, anxiety, and stress), PASS (escape avoidance, cognitive anxiety, fear of pain, and physiological anxiety), and PCS (rumination, magnification, and helplessness) was significantly higher in the CP group compared to the RA group. Categorization of individuals based on DASS severity resulted in significant differences in rates of depression and anxiety symptoms between groups, with a greater number of CP participants displaying more severe depressive and anxiety symptoms. Discussion and Conclusions. This study found greater levels of psychological distress among CP individuals referred to an academic pain clinic when compared to RA patients referred to an academic rheumatology clinic.

Pain afflflicts over 50 million people in the US, with 30.7% US adults suffering with chronic pain. Despite advances in therapies, many patients will continue to deal with ongoing symptoms that are not fully addressed by the best conventional medicine has to offer them. The patients frequently turn to therapies outside the usual purview of conventional medicine (herbs, acupuncture, meditation, etc.) called complementary and alternative medicine (CAM). Academic and governmental groups are also starting to incorporate CAM recommendations into chronic pain management strategies. Thus, for any physician who care for patients with chronic pain, having some familiarity with these therapies-including risks and benefits-will be key to helping guide patients in making evidence-based, well informed decisions about whether or not to use such therapies. On the other hand, if a CAM therapy has evidence of both safety and efficacy then not making it available to a patient who is suffering does not meet the need of the patient. We summarize the current evidence of a wide variety of CAM modalities that have potential for helping patients with chronic pain in this article. The triad of chronic pain symptoms, ready access to information on the internet, and growing patient empowerment suggest that CAM therapies will remain a consistent part of the healthcare of patients dealing with chronic pain.

Full Text Available John A Sturgeon Department of Anesthesiology, Stanford University, Palo Alto, CA, USA Abstract: Pain is a complex stressor that presents a significant challenge to most aspects of functioning and contributes to substantial physical, psychological, occupational, and financial cost, particularly in its chronic form. As medical intervention frequently cannot resolve pain completely, there is a need for management approaches to chronic pain, including psychological intervention. Psychotherapy for chronic pain primarily targets improvements in physical, emotional, social, and occupational functioning rather than focusing on resolution of pain itself. However, psychological therapies for chronic pain differ in their scope, duration, and goals, and thus show distinct patterns of treatment efficacy. These therapies fall into four categories: operant-behavioral therapy, cognitive-behavioral therapy, mindfulness-based therapy, and acceptance and commitment therapy. The current article explores the theoretical distinctiveness, therapeutic targets, and effectiveness of these approaches as well as mechanisms and individual differences that factor into treatment response and pain-related dysfunction and distress. Implications for future research, dissemination of treatment, and the integration of psychological principles with other treatment modalities are also discussed.

Full Text Available OBJECTIVE: To identify the prevalence and characteristics of chronic pain in schizophrenic patients and to compare the quality of life in patients with and without chronic pain. METHODS: Crossover design with a probablistic sample of 205 adult schizophrenic outpatients (80% paranoid schizophrenia. Socio-demographic, psychiatric disorder, pain and quality of life (WHOQOL- brief data were collected between June and September 2008. RESULTS: Mean age was 37 years, 65% were men, and the mean time spent in school was 9 years; 87% were single, 65% lived with parents and 25% had a job. Among patients with chronic pain, 70% did not receive treatment for pain. Regarding quality of life, patients with pain had more physical disabilities compared to those without pain (p < .001. There were no differences in other domains. Comparisons between patients with and without pain did not show any differences in how much they felt their mental health problems disabled them. Conclusion: Chronic pain was common in schizophrenic patients (similar to the general population of a similar age and decreased their quality of life. It is necessary to pay more attention to this co-morbidity.
Full Text Available Abstract Objectives Alexithymia is highly prevalent among chronic pain patients. Pain is a remarkable cause for high levels of chronic anxiety. The purpose of this study was to investigate the prevalence of alexithymia and to determine anxiety levels among DSM-IV somatoform pain disorder (chronic pain female patients and to examine the relationship between alexithymia and the self-reporting of pain. Methods Thirty adult females (mean age: 34,63 ± 10,62 years, who applied to the outpatient psychiatry clinic at a public hospital with the diagnosis of chronic pain disorder (DSM-IV, were included in the study. Thirty seven healthy females (mean age: 34,46 ± 7,43 years, who matched for sociodemographic features with the patient group, consisted the control group. A sociodemographic data form, 26-item Toronto Alexithymia Scale (TAS-26, Spielberger Trait Anxiety Inventory (STAI were administered to each subject and information was obtained on several aspects of the patients' pain, including intensity (measured by VAS, and duration. Results Chronic pain patients were found significantly more alexithymic than controls. There was a positive correlation between TAS-26 scores and the duration of pain. The alexithymic and nonalexithymic group did not differ in their perception of pain. Neither positive correlation nor significant difference was found between alexithymia and trait anxiety in pain patients. Discussion Alexithymia may be important in addressing the diversity of subjective factors involved in pain. The conceptualization of alexithymia as a personality trait as well as a secondary state reaction is underlined by our data.

Methods One hundred and seventy-six patients who underwent surgery through temporal approach were divided into 3 groups and treated with morphine 30 mg (Group M, N = 57, tramadol 1000 mg (Group T, N = 60 and morphine 20 mg + flurbiprofen 200 mg (Group F, N = 59 by patient-controlled intravenous analgesia (PCIA. Postoperative acute pain (resting and movement was evaluated by Visual Analogue Scale (VAS at 4, 16, 24 and 48 h respectively. Chronic pain was measured by Short-Form McGill Pain Questionnaire (SF-MPQ 3 months after surgery. The characteristics of acute and chronic pain, the relationship between them and analgesic effect of 3 kinds of analgesic drugs were analyzed. Results The differences of observed indicators including gender, age, weight and operating time, which might affect the degree of postoperative pain between before and after surgery were not statistically significant (P > 0.05. VAS scores at different time points within 48 h after surgery in each group decreased gradually. The VAS scores in group T (2.91 ± 1.64 was significantly higher than group M (2.19 ± 1.68 and group F (1.71 ± 1.17, P 0.05. The overall incidence rate of chronic pain was 71.02% (125/176, with moderate and severe pain in 15.91% (28/176. Chronic pain and acute postoperative pain severity were positively correlated (resting: rs = 0.171, P = 0.012; movement: rs = 0.190, P = 0.006. The difference of the acute pain (VAS corresponding to SF-MPQ Ⅱ score > 0 and SF-MPQ Ⅱ score = 0 was statistically significant (P < 0.05. Conclusion The postoperative chronic pain following temporal craniotomy is related to acute pain within 48 h after operation. Effective treatment of early postoperative acute pain may reduce the incidence of chronic pain.

Pain burden is high in people living with HIV (PLWH), but the effect of this pain on functionality is equivocal. Resilience, the ability to cope with adversity, may promote adaptation to pain, so we hypothesised that higher resilience would correlate with less pain-related impairment of activity. We recruited 197 black South African PLWH, 99 with chronic pain (CP) and 98 patients without. We measured pain intensity and interference using the Brief Pain Inventory, and resilience using the Resilience Scale. Participants were generally highly resilient. Greater resilience correlated with better health-related quality of life, but not with pain intensity or interference. We also measured physical activity objectively, by actigraphy, in a subset of patients (37 with chronic pain and 31 without chronic pain), who wore accelerometers for two weeks. There was no difference in duration or intensity of activity between those with and without pain, and activity was not associated with resilience. In this sample, pain was not associated with altered physical activity. Resilience did not explain differences in pain intensity or pain interference but was associated with improved quality of life. Financial stresses and the fear of HIV stigma may have driven patients to conceal pain and to suppress its expected impairment of activity. PMID:27672513
Full Text Available Patients with chronic pain and depression are more likely to develop opioid abuse compared to patients without depression. It is not known if this association differs by pain location. We compared the strength of association between depression and opioid misuse in patients with chronic low back pain (CLBP vs. chronic pain of other location (CPOL. Chart abstracted data was obtained from 166 patients seeking care in a family medicine clinic. Depression was measured by the PHQ-9 and opioid misuse was measured using the Current Opioid Misuse Measure. Pain severity and interference questions came from the Brief Pain Inventory. Cross-tabulations were computed to measure the association between depression and opioid misuse stratified on pain location. Exploratory logistic regression modeled the association between depression and opioid misuse after adjusting for pain location and pain severity and interference. Depression was significantly associated with opioid misuse in CPOL but not in CLBP. Regression results indicate pain interference partly accounts for the depression–opioid misuse association. These preliminary results from a small patient sample suggest depression may co-occur with opioid misuse more often in CPOL than in CLBP. Further research is needed to compare this comorbidity in specific pain diagnoses such as arthritis, fibromyalgia and CLBP.

The purpose of this pilot study is to evaluate the feasibility of a cognitive-behavioural training program for adolescents with chronic pain irrespective of pain localisation. A secondary aim was to give an impression of the effect of the program on pain and quality of life. Eight adolescents (14-18 years) with chronic non-organic pain recruited from the general population (and their parents) participated in this pilot study. The intervention included five group meetings alternated with four telephone contacts (during the self-management weeks) over a period of 9 weeks. The training aimed to change pain behaviour through pain education, relaxation strategies, problem-solving techniques, assertiveness training, cognitive restructuring and by stimulating the adolescent's physical activity level. The training further addresses the social context of pain by inviting parents to attend two meetings for the parents only, and by asking the adolescents to bring a peer to one of the meetings. Adolescents and their parents were positive about the program. Adolescents felt they were more in control of their pain and parents valued the support they experienced in helping their children to master the pain. The training was considered to be feasible in daily life. Further, the preliminary data showed an effect on pain and quality of life in the expected direction. The results underline the need for a definitive study with a larger sample size and a random controlled design. PMID:16257616
This article presents the results of a collaborative project between the British Pain Society and British Geriatric Society to produce guidelines on the management of pain in older adults. The guidelines are the first of their kind in the UK and aim to provide best practice for the management of pain to all health professionals working with older adults in any care setting.

Chronic pain is a complex phenomenon that causes a significant disruption in the lives of those affected. Chronic pain is difficult to treat and challenges healthcare professionals' abilities to implement effective treatments. Therefore, chronic pain sufferers often seek complementary alternative medicine therapies such as meditation. Literature reviews have examined studies using mindfulness-based stress reduction program as an intervention for a variety of health problems. However, no reviews exist looking at a specific patient population's utilization of meditation-based programs. Therefore, the purpose of this integrative review is to examine studies that have investigated meditation as an intervention for chronic pain, identify gaps in the literature, and make recommendations for further research.

Full Text Available This paper proposes phenomenological notions of self-image and body schema as an explicative and clinical possibility for the relationship between hypnosis and chronic pain. It begins with a critique of the medical and nomothetic approach taken by contemporary research that does not usually address clinical issues, and then addresses a case study where a person suffering from chronic pain related both body schema and self-image is submitted to hypnotherapy. The study concludes that there is no linear relationship between such notions and that chronic pain is uniquely configured to each person. This requires a clinical and qualitative approach to access and understand chronic pain, both in terms of classic phenomenological notions of time, space, and material experiences, as well as socio-cultural dimensions that contribute to producing feelings related to the daily experiences of the subjects.

This investigation was conducted to test the accuracy of unassisted pain maps drawn by patients with chronic pain. Three aspects of accuracy were investigated, the accuracy of the area of pain reported, whether all existing pains were reported, and whether related symptoms were reported. Thirty-six successive new admissions to a chronic pain rehabilitation center were used as subjects. Each patient filled out the pain map prior to meeting any professional staff. During their examination the investigators completed a new pain map without seeing the patient's map. Thirty-one pairs of pain maps were compared and scored, with most maps showing several pain areas. Area of pain was accurately represented 43% of the time. Of 139 distinct pains found during examination, only 58% were reported in the pain maps. Thirtyfour percent of related symptoms were reported. It appears that unassisted pain maps are sufficiently flawed to discourage their use as an indicator of the patients symptom location J Orthop Sports Phys Ther 1987;8(8):391-396.

Chronic pain is more prevalent in women than in men, with increasing differences between sexes in advanced age. This could be caused by differences in sex hormone levels. We therefore studied the relationship between sex hormones and the prevalence and incidence of chronic pain. The association between sex hormone levels and chronic pain was examined in 9717 participants aged 45 years and older from the Rotterdam Study, a population-based study. Chronic pain was defined as pain in the lower back, hands, knees and/or hips for at least 3 months. Sex hormone levels included estrogen, testosterone, androstenedione, and 17-hydroxyprogesterone. Relationships between hormones and prevalent and new onset chronic pain were analyzed using linear and logistic regression, stratified by gender. Women with androstenedione or estradiol levels in the lowest tertile had more chronic pain (odds ratio, 1.20; 95% CI, 1.03-1.39 and odds ratio, 1.27; 95% CI, 1.10-1.48, respectively). Mean estradiol levels were lower among men with chronic pain (mean difference -3.88 pmol/L; P = 0.005). Lowest tertile 17-hydroxyprogesterone in women was associated with 38% more new onset pain. All these associations were independent from age, body mass index, health and lifestyle factors, and osteoarthritis. Lower sex hormone levels are associated with chronic musculoskeletal pain, independent from lifestyle and health-related factors, in community-dwelling elderly women. These results suggest that sex hormones play a role in chronic pain and should be taken into account when a patient presents with chronic pain. Therefore, sex hormones may be a potential treatment target for these patients. PMID:27331348

Noninvasive treatments for chronic pain syndrome benefit in 80-90% of cancer patients. Invasive, intervention procedures for analgesia should be used in other cases. These include neuroablative and neuromodulatory measures. Neuroablation is defined as the physical suspension of painful impulse transmission pathways by a surgical, chemical, or thermal method and comprises lytic and other blocks.

Chronic pain plagues older adults more than any other age group; thus, practitioners must be able to approach this problem with confidence and skill. This article reviews the assessment and treatment of the most common chronic nonmalignant pain conditions that affect older adults--myofascial pain, generalized osteoarthritis, chronic low back pain (CLBP), fibromyalgia syndrome, and peripheral neuropathy. Specific topics include essential components of the physical examination; how and when to use basic and advanced imaging in older adults with CLBP; a stepped care approach to treating older adults with generalized osteoarthritis and CLBP, including noninvasive and invasive management techniques; how to diagnose and treat myofascial pain; strategies to identify the older adult with fibromyalgia syndrome and avoid unnecessary "diagnostic" testing; pharmacological treatment for the older adult with peripheral neuropathy; identification and treatment of other factors such as dementia and depression that may significantly influence response to pain treatment; and when to refer the patient to a pain specialist. While common, chronic pain is not a normal part of aging, and it should be treated with an emphasis on improved physical function and quality of life.

Full Text Available Hans Verstraelen,1 Eline De Zutter,1 Martine De Muynck2 1Department of Obstetrics and Gynaecology, Vulvovaginal Disease Clinic, Ghent University Hospital, Ghent, Belgium; 2Department of Physical Medicine and Rehabilitation, Ghent University Hospital, Ghent, Belgium Abstract: The vulva is a particularly common locus of chronic pain with neuropathic characteristics that occurs in women of any age, though most women with neuropathic type chronic vulvar pain will remain undiagnosed even following multiple physician visits. Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain. Keywords: vulvar pain, genitofemoral nerve, neuropathic pain, vulvodynia, vulvar disease

Full Text Available Chronic pain is a major health concern that affects millions of people. There are no adequate long-term therapies for chronic pain sufferers, leading to significant cost for both society and the individual. The most commonly used therapy for chronic pain is the application of opioid analgesics and nonsteroidal anti-inflammatory drugs, but these drugs can lead to addiction and may cause side effects. Further studies of the mechanisms of chronic pain have opened the way for development of new treatment strategies, one of which is gene therapy. The key to gene therapy is selecting safe and highly efficient gene delivery systems that can deliver therapeutic genes to overexpress or suppress relevant targets in specific cell types. Here we review several promising viral vectors that could be applied in gene transfer for the treatment of chronic pain and further discuss the possible mechanisms of genes of interest that could be delivered with viral vectors for the treatment of chronic pain.

Behavioural symptoms such as abnormal emotionality (including anxious and depressive episodes) and cognition (for instance weakened decision-making) are highly frequent in both chronic pain patients and their animal models. The theory developed in the present article posits that alterations in glial cells (astrocytes and microglia) in cortical and limbic brain regions might be the origin of such emotional and cognitive chronic pain-associated impairments. Indeed, in mood disorders (unipolar depression, anxiety disorders, autism or schizophrenia) glial changes in brain regions involved in mood control (prefrontal and cingulate cortices, amygdala and the hippocampus) have been recurrently described. Besides, glial cells have been undoubtedly identified as key actors in the sensory component of chronic pain, owing to the profound phenotypical changes they undergo throughout the sensory pathway. Hence, the possibility arises that brain astrocytes and microglia react in upper brain structures as well, mediating the related mood and cognitive dysfunctions in chronic pain. So far, only very few studies have provided results in this prospect, mainly indirectly in pain-independent researches. Nevertheless, the first scant available data seem to merge in a unified description of a brain glial reaction occurring after chronic peripheral lesion. The present article uses this scarce literature to formulate the provocative theory of a glia-driven mood and cognitive dysfunction in chronic pain, expounding upon its validity and putative therapeutical impact as well as its current limitations and expected future developments.

Full Text Available Chronic pain is a common disorder with a high prevalence of psychiatric disorder that imposes a worse prognosis on both conditions. Obsessive compulsive disorder (OCD is estimated to be the fourth most prevalent life time psychiatric disorder, but yet has gained less attention in chronic pain comorbidity researches.Ninety three heterogeneous chronic pain patients who attended a pain clinic in Tehran (Iran in an outpatient setting during three months were included in this study. Diagnosis was made by Structured Clinical Interview for DSM-IV (SCID.The mean age of the patients was 46.37 (SD 15.005 years; of the patients, 66.7% were female and 33.3% were male. The mean duration of pain was 34.43 (SD 51.422 months. The mean pain severity on numerical pain scale was 5.82 (SD 1.950 from 10. The mean pain site number was 3.68 (SD 3.401 from the maximum of 27 places. Furthermore, 61.3% of the participants were diagnosed with lifetime OCD, 25.8% with subclinical OCD and 61.5 % with major depressive disorder (MDD. OCD diagnosis was not correlated with MDD or pain intensity. Female gender was associated with OCD (OD; 4.182, 95% CL (1.655-10.568. Pain intensity was correlated with MDD (P < 0.05.The high prevalence of OCD was comorbidity, independent of MDD and most pain characteristics. The high prevalence of OCD may be explained by the high rate of undiagnosed cause of pain as well as cultural and local factors. Using screening tests is suggested for tackling under diagnosis and under treatment of OCD and MDD.

During the past decade, scientific research has provided new insight into the development from an acute, localised musculoskeletal disorder towards chronic widespread pain/fibromyalgia (FM). Chronic widespread pain/FM is characterised by sensitisation of central pain pathways. An in-depth review of basic and clinical research was performed to design a theoretical framework for manual therapy in these patients. It is explained that manual therapy might be able to influence the process of chronicity in three different ways. (I) In order to prevent chronicity in (sub)acute musculoskeletal disorders, it seems crucial to limit the time course of afferent stimulation of peripheral nociceptors. (II) In the case of chronic widespread pain and established sensitisation of central pain pathways, relatively minor injuries/trauma at any locations are likely to sustain the process of central sensitisation and should be treated appropriately with manual therapy accounting for the decreased sensory threshold. Inappropriate pain beliefs should be addressed and exercise interventions should account for the process of central sensitisation. (III) However, manual therapists ignoring the processes involved in the development and maintenance of chronic widespread pain/FM may cause more harm then benefit to the patient by triggering or sustaining central sensitisation.

METHODS: This was a prospective consecutive case series study by questionnaire of 500 consecutive operations in 466 unselected adult...... severe pain 4 weeks after operation (24 versus 3 per cent; P < 0.001). CONCLUSION: Chronic pain is a significant problem after open groin hernia repair. It may be worse after surgery for a recurrent hernia and may be predicted by the intensity of early postoperative pain....... severe pain was higher after repair of recurrent than primary hernias (14 versus 3 per cent; P < 0.001). The risk of developing moderate or severe pain was increased in patients who had a high pain score 1 week after operation (9 versus 3 per cent; P < 0.05) and also in patients who had moderate or...

Most methods used in humans are reliable and have face validity to detect widespread central hypersensitivity. However, construct validity is difficult to investigate due to lack of gold...... standards. Reference values in the pain-free population have been generated, but need replication. Research on pain biomarkers that reflect specific central hypersensitivity processes is warranted. Few studies have analyzed the prognostic value of central hypersensitivity.

Chronic pain represents a challenge to patients, families, employers, and the physicians who care for these individuals. Opioids remain the mainstay of the analgesic medications for the treatment of both acute and chronic pain. Controlled release preparations of morphine, oxycodone, fentanyl and long acting opioid agents such as methadone and levorphanol have been medically and ethically accepted in managing chronic cancer pain. However, the continued use of these medications for patients with chronic noncancer pain has been fiercely debated. This article attempts to reconcile the medical and ethical dilemma of using opioid medications for chronic noncancer pain. Growing clinical experience in the field of pain medicine has helped to clarify: (1) the misunderstanding of addiction, physical dependence and analgesic tolerance, (2) the misconception that chronic opioid therapy inevitably causes personality changes, depression, and impairment of cognitive and physical function, (3) the lack of information on the correct use of opioid analgesics with regard to titration and management of related side effects. The behavioral management of pain patients undergoing chronic opioid therapy is also discussed. A protocol for optimal patient management is proposed. Particular emphasis is given to the consent form, behavioral contracting, and the consequences of noncompliance. The importance of psychologic evaluation before a long-term opioid trial, to minimize future complications, is stressed. Although most patients on the opioid regimen do well, special attention must be given to patients with current addiction, a past history of addiction, or current misuse of opioid medications. Pharmacologic and conservative interventions are often warranted in those patients with significant behavioral problems. If such strategies fail, and chronic opioid therapy is deemed necessary, some treatment guidelines are offered. PMID:9311061

It has proven difficult to use systemic administration of small molecules to selectively modulate nociception. Over the past decade, we and others have developed non-replicating herpes simplex virus (HSV)-based vectors to treat chronic pain. Subcutaneous inoculation of an HSV vector effectively transduces sensory neurons in the dorsal root ganglion; release of transgene-coded inhibitory neurotransmitters or anti-inflammatory peptides reduces pain-related behaviors in rodent models of chronic inflammatory and neuro-pathic pain. A phase 1 trial of this therapy in patients is set to begin soon.
Full Text Available BACKGROUND: The intervention of pacing is regularly recommended for chronic pain patients. However, pacing is poorly defined and appears to be interpreted in varying, potentially contradictory manners within the field of chronic pain. This conceptual lack of clarity has implications for effective service delivery and for researchers’ ability to conduct rigorous study. An examination of the background literature demonstrates that while pacing is often one part of a multidisciplinary pain management program, outcome research is hindered by a lack of a clear and shared definition of this currently ill-defined construct.

Musculoskeletal conditions are the most frequent cause of chronic pain and affect around 1 in 5 adults in Europe. When chronic pain occurs, it becomes disease itself, with substantial clinical, social and economic impact. Efficacy and tolerability problems are encountered with all therapeutic strategies available to treat musculoskeletal pain. This often limits effective analgesia and patients' long term compliance, with the result that chronic pain is persistently underestimated and undertreated. Tapentadol is a novel, centrally acting analgesic that has been recently commercialized for the treatment of chronic pain. This new molecule, by combining two distinct mechanisms of action, μ-opioid receptor agonism (MOR) and noradrenaline reuptake inhibition (NRI), introduces a new pharmacological class called MOR-NRI. Several studies demonstrated promising results in the management of both nociceptive and neuropathic pain and good tolerability profile, particularly concerning side effects, compared to traditional opioids. This novel analgesic represents a possible therapeutic option also in the rheumatologic field, particularly in the treatment of osteoarthritis and low back pain. PMID:26492961

Chronic pain affects a large proportion of the population, imposing significant individual distress and a considerable burden on society, yet treatment is not always instituted and/or adequate. Comprehensive multidisciplinary management based on the biopsychosocial model of pain has been shown to be clinically effective and cost-efficient, but is not widely available. A literature review of stakeholder groups revealed many reasons for this, including: i) many patients believe healthcare professionals lack relevant knowledge, and consultations are rushed, ii) general practitioners consider that pain management has a low priority and is under-resourced, iii) pain specialists cite non-adherence to evidence-based treatment, sub-optimal prescribing, and chronic pain not being regarded as a disease in its own right, iv) nurses', pharmacists' and physiotherapists' skills are not fully utilized, and v) psychological therapy is employed infrequently and often too late. Many of the issues relating to physicians could be addressed by improving medical training, both at undergraduate and postgraduate levels - for example, by making pain medicine a compulsory core subject of the undergraduate medical curriculum. This would improve physician/patient communication, increase the use of standardized pain assessment tools, and allow more patients to participate in treatment decisions. Patient care would also benefit from improved training for other multidisciplinary team members; for example, nurses could provide counseling and follow-up support, psychologists offer coping skills training, and physiotherapists have a greater role in rehabilitation. Equally important measures include the widespread adoption of a patient-centered approach, chronic pain being recognized as a disease in its own right, and the development of universal guidelines for managing chronic non-cancer pain. Perhaps the greatest barrier to improvement is lack of political will at both national and international

The purpose of this study was to explore the literature on chronic pain in adults with Marfan syndrome (MFS), critically appraising and synthesizing relevant literature. A systematic review was conducted by searching the published literature databases using available medical, physical, psychological, social databases and other sources. All studies that addressed pain in MFS, published in peer-reviewed journals were assessed. Of 351 search results, 18 articles satisfied the eligibility criteria. All studies were cross-sectional and quantitative; no randomized controlled trials or intervention studies were found. Most studies had small sample sizes, low response rates and mainly dealt with other aspects of the diagnosis than pain. Only one article dealt mainly with pain. The research on chronic pain in MFS is limited in size and quality. Despite these limitations, studies describe that the prevalence of pain in patients with MFS is high, varying from 47 to 92% and affecting several anatomic sites. In addition, chronic pain limits daily function and few studies describe treatment options for pain in patients with MFS. Research is needed to obtain more evidence-based knowledge for developing more appropriate rehabilitation programs for people with MFS. PMID:26607862

The February-March 2014 special issue of the American Psychologist featured articles summarizing select contributions from the field of psychology to the assessment and treatment of chronic pain. The articles examined a range of psychosocial and family factors that influence individual adjustment and contribute to disparities in pain care. The reviews also considered the psychological correlates and neurophysiological mechanisms of specific pain treatments, including cognitive-behavioral therapy, hypnosis, acceptance and commitment therapy, mindfulness, and meditation. Although a number of articles emphasized the role that negative states of mind play in pain outcomes, positive emotions were given only brief mention. Here, we provide a rationale for the inclusion of positive emotions in chronic pain research. PMID:25844656

Overall the qualitative accounts of experience revealed that the smartphone application allowed individuals to reflect upon their chronic pain experience in a way which was different to their normal everyday lives. It built up a more ecological and meaningful picture of the pain experience to the participants. The findings also raised some interesting issues surrounding the use of pain scales, the individuality of experience, and how smartphone applications are interpreted and integrated into everyday life. The findings have built upon previous research in this area by providing deeper accounts of insider experience, this enhances our understandings of smartphone application usage in those living with chronic pain.

Spinal cord stimulation (SCS) suppresses visceral response to colon distension in an animal model. In humans, it may be an effective therapy for chronic pain of pelvic origin, irritable bowel syndrome, and persistent unspecified abdominal pain. Described here is the case of SCS for 38-year-old woman with visceral pain secondary to chronic pancreatitis. Previous therapies included numerous endoscopic retrograde cholangiopancreatographies, multiple pancreatic duct stenting, chemical and surgical sympathectomies with short-lasting pain relief. After the initial evaluation, the patient underwent retrograde epidural differential block to determine possible source of pain. Delay in pain recurrence after block suggested that the origin of her pain was visceral. After the psychologic evaluation, the patient underwent SCS trial over 14 days. She had 2 trial leads placed epidurally via T9-T10 paramedian entry with the tips of both leads positioned at T6 vertebral body. During the trial, visual analog scale pain score decreased from 8 to 1 cm, Pain Disability Index from 62 to 14, and opioid use from 150 to 0 mg of morphine sulfate equivalent a day. After the completion of successful SCS trial, she was implanted with dual octrode leads and rechargeable pulse generator. Median pain scores decreased from 8 to 1 at 3 months after the implant. Pain Disability Index changed from 62 to 15. Opiate use decreased to none. It seems that SCS may have a significant therapeutic potential for the treatment of visceral pain secondary to chronic pancreatitis. PMID:18496389
Full Text Available The psychological concept of acceptance has been increasingly considered in the process of chronic pain acceptance. The concept includes exposure to pain experienced without attempts of avoidance or control, and persistence in the physical activity in spite of chronic pain. At the University Rehabilitation Institute (URI in Ljubljana, we are using the Slovenian version of the Chronic Pain Acceptance Questionnaire (CPAQ; McCracken et al., 2004 for measuring the concept of acceptance. The aim of our study was to investigate its construct validity (fit of the two-factor model, i.e., the division of the 20 items into the Pain Willingness and Activity Engagement scales and its internal-consistency and retest reliability. The study included 241 participants who were examined at the outpatient clinic for patients with chronic non-malignant pain at the URI between March 2011 and June 2013. All of them completed the CPAQ. Confirmatory factor analysis and item analysis both pointed to inadequacy of the item No. 16, which should be either excluded or reworded. In general, reliability of the questionnaire (internal consistency of the two scales and of the total score, as well as retest reliability proved to be adequate for research application.

Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that refer pain to adjacent sites. Effective treatments are available to reduce MFPP, including myofascial trigger point release, biofeedback, and electrical stimulation. An interdisciplinary team is essential for identifying and successfully treating MFPP.

Background: This study aimed to answer three questions related to chronic myofascial pain syndrome (MPS): 1) Is the motor cortex excitability, as assessed by transcranial magnetic stimulation parameters (TMS), related to state-trait anxiety? 2) Does anxiety modulate corticospinal excitability changes after evoked pain by Quantitative Sensory Testing (QST)? 3) Does the state-trait anxiety predict the response to pain evoked by QST if simultaneously receiving a heterotopic stimulus [Conditional...
Full Text Available Cluster headache (CH is a chronic syndrome characterized by excruciatingly painful attacks occurring with circadian and circannual periodicity. The objectives of the present study were, in CH patients, to determine by principal component analysis the factor structure of two instruments commonly used in clinics to evaluate pain locus of control (Cancer Locus of Control Scale–CLCS and coping strategies (Coping Strategies Questionnaire–CSQ, to examine the relationship between internal pain controllability and emotional distress, and to compare psychosocial distress and coping strategies between two subsets of patients with episodic or chronic CH. Results indicate, for CLCS, a 3-factor structure (internal controllability, medical controllability, religious controllability noticeably different in CH patients from the structure reported in patients with other painful pathologies and, for CSQ, a 5-factor structure of CSQ which did not markedly diverge from the classical structure. Perceived internal controllability of pain was strongly correlated with study measures of depression (HAD depression/anhedonia subscale, Beck Depression Inventory. Comparison between subsets of patients with episodic or chronic CH of emotional status, pain locus of control, perceived social support and coping strategies did not reveal significant differences apart for the Reinterpreting pain sensations strategy which was more often used by episodic CH patients. Observed tendencies for increased anxiety and perceived social support in patients with episodic CH, and for increased depression and more frequent use of the Ignoring pain sensations strategy in patients with chronic CH, warrant confirmation in larger groups of patients.

Sleep disturbance is becoming increasingly recognised as a clinically important symptom in people with chronic low back pain (CLBP, low back pain >12 weeks), associated with physical inactivity and depression. Current research and international clinical guidelines recommend people with CLBP assume a physically active role in their recovery to prevent chronicity, but the high prevalence of sleep disturbance in this population may be unknowingly limiting their ability to participate in exercise-based rehabilitation programmes and contributing to poor outcomes. There is currently no knowledge concerning the effectiveness of physiotherapy on sleep disturbance in people with chronic low back pain and no evidence of the feasibility of conducting randomized controlled trials that comprehensively evaluate sleep as an outcome measure in this population.

When a child has chronic pain, it affects the parents. Their response and how it is factored into their lives and family function was the phenomenon of interest that drove this study. The available literature was sparse, especially when the pain etiology was neuropathic. The purpose of this study was to describe the parents' perception of the pain journey from the initial occurrence of their child's pain through the labyrinth of treatment options to successful outcome, to gain a better understanding of parental beliefs about pain, and to learn how parental attitudes and behaviors relate to children's response to treatment for chronic pain. Qualitative descriptive design was used to better understand the phenomenon from those who were the experts because they had experienced it. Parents whose child was enrolled in a pain rehabilitation program participated in open-ended interviews. The children/adolescents were 8-18 years old and diagnosed with complex regional pain syndrome or a related chronic pain condition. During data immersion, the investigators uncovered the pervasive underlying themes of suffering and disempowerment. In addition, the multiple meaning elements were grouped into three categories and supportive subcategories labeled as follows: parent distress, with subcategories schism in parenting, searching, and disabled parenting; and lack of control, with the subcategories family/community, fear, and empowerment. The voices of parents were heard in their description of the exhausting and difficult journey in search of pain relief for their child. Their comments provided insight into how they defined the child's pain and their related parental role.

Full Text Available Shai N Gozani NeuroMetrix, Inc., Waltham, MA, USA Objective: The objective of this study was to determine if fixed-site high-frequency transcutaneous electrical nerve stimulation (FS-TENS is effective in treating chronic low back and lower extremity pain. Background: Transcutaneous electrical nerve stimulation is widely used for treatment of chronic pain. General-purpose transcutaneous electrical nerve stimulation devices are designed for stimulation anywhere on the body and often cannot be used while the user is active or sleeping. FS-TENS devices are designed for placement at a pre-determined location, which enables development of a wearable device for use over extended time periods. Methods: Study participants with chronic low back and/or lower extremity pain self-administered an FS-TENS device for 60 days. Baseline, 30-, and 60-day follow-up data were obtained through an online questionnaire. The primary outcome measure was the patient global impression of change. Pain intensity and interference were assessed using the Brief Pain Inventory. Changes in use of concomitant pain medications were evaluated with a single-item global self-rating. Results: One hundred and thirty participants were enrolled, with 88 completing the 60-day follow-up questionnaire. Most participants (73.9% were 50 years of age or older. At baseline, low back pain was identified by 85.3%, lower extremity pain by 71.6%, and upper extremity pain by 62.5%. Participants reported widespread pain, at baseline, with a mean of 3.4 (standard deviation 1.1 pain sites. At the 60-day follow-up, 80.7% of participants reported that their chronic pain had improved and they were classified as responders. Baseline characteristics did not differentiate non-responders from responders. There were numerical trends toward reduced pain interference with walking ability and sleep, and greater pain relief in responders.

Full Text Available Objectives. This prospective, randomized clinical trial (RCT was designed to investigate the feasibility and effects of a 4-week auricular point acupressure (APA for chronic low back pain (CLBP. Methods. Participants were randomized to either true APA (true acupoints with taped seeds on the designated ear points for CLBP or sham APA (sham acupoints with taped seeds but on different locations than those designated for CLBP. The duration of treatment was four weeks. Participants were assessed before treatment, weekly during treatment, and 1 month following treatment. Results. Participants in the true APA group who completed the 4-week APA treatment had a 70% reduction in worst pain intensity, a 75% reduction in overall pain intensity, and a 42% improvement in disability due to back pain from baseline assessment. The reductions of worst pain and overall pain intensity in the true APA group were statistically greater than participants in the sham group (P<0.01 at the completion of a 4-week APA and 1 month followup. Discussion. The preliminary findings of this feasibility study showed a reduction in pain intensity and improvement in physical function suggesting that APA may be a promising treatment for patients with CLBP.

Pain neuroscience education (PNE) is increasingly used as part of a physical therapy treatment in patients with chronic pain. A thorough clinical biopsychosocial assessment is recommended prior to PNE to allow proper explanation of the neurophysiology of pain and the biopsychosocial interactions in an interactive and patient-centered manner. However, without clear guidelines, clinicians are left wondering how a biopsychosocial assessment should be administered. Therefore, we provided a practical guide, based on scientific research and clinical experience, for the biopsychosocial assessment of patients with chronic pain in physiotherapy practice. The purpose of this article is to describe the use of the Pain - Somatic factors - Cognitive factors - Emotional factors - Behavioral factors - Social factors - Motivation - model (PSCEBSM-model) during the intake, as well as a pain analysis sheet. This model attempts to clearly establish what the dominant pain mechanism is (predominant nociceptive, neuropathic, or non-neuropathic central sensitization pain), as well as to assess the provoking and perpetuating biopsychosocial factors in patients with chronic pain. Using this approach allows the clinician to specifically classify patients and tailor the plan of care, including PNE, to individual patients. PMID:27351769

There is evidence for the efficacy of acupuncture treatment for chronic shoulder pain, but it remains unclear which acupuncture modes are most effective. We compared the effect of trigger point acupuncture (TrP), with that of sham (SH) acupuncture treatments, on pain and shoulder function in patients with chronic shoulder pain. The participants were 18 patients (15 women, 3 men; aged 42-65 years) with nonradiating shoulder pain for at least 6 months and normal neurological findings. The participants were randomized into two groups, each receiving five treatment sessions. The TrP group received treatment at trigger points for the muscle, while the other group received SH acupuncture treatment on the same muscle. Outcome measures were pain intensity (visual analogue scale, VAS) and shoulder function (Constant-Murley Score: CMS). After treatment, pain intensity between pretreatment and 5 weeks after TrP decreased significantly (pShoulder function also increased significantly between pretreatment and 5 weeks after TrP (pshoulder pain.

Internet-based educational and therapeutic programs (e-health applications) are becoming increasingly popular for a variety of psychological and physical disorders. We tested the efficacy of an online Chronic Pain Management Program, a comprehensive, fully self-directed and self-paced system that integrates social networking features and self-management tools into an interactive learning environment. Of 305 adult participants (196 women, 109 men), a total of 162 individuals with chronic pain were randomly assigned unsupervised access to the program for approximately 6 weeks; 143 were assigned to the wait-listed control group with treatment as usual. A comprehensive assessment was administered before the study and approximately 7 and 14 weeks thereafter. All recruitment, data collection, and participant involvement took place online. Participation was fully self-paced, permitting the evaluation of program effectiveness under real-world conditions. Intent-to-treat analysis that used linear growth models was used as the primary analytic tool. Results indicated that program utilization was associated with significant decreases in pain severity, pain-related interference and emotional burden, perceived disability, catastrophizing, and pain-induced fear. Further, program use led to significant declines in depression, anxiety, and stress. Finally, as compared to the wait-listed control group, the experimental group displayed a significant increase in knowledge about the principles of chronic pain and its management. Study limitations are considered, including the recognition that not all persons with chronic pain are necessarily good candidates for self-initiated, self-paced, interactive learning. PMID:22133450

Full Text Available Chronic pain has been associated with impaired cognitive function. We examined cognitive performance in patients with severe chronic pancreatitis pain. We explored the following factors for their contribution to observed cognitive deficits: pain duration, comorbidity (depression, sleep disturbance, use of opioids, and premorbid alcohol abuse. The cognitive profiles of 16 patients with severe pain due to chronic pancreatitis were determined using an extensive neuropsychological test battery. Data from three cognitive domains (psychomotor performance, memory, executive functions were compared to data from healthy controls matched for age, gender and education. Multivariate multilevel analysis of the data showed decreased test scores in patients with chronic pancreatitis pain in different cognitive domains. Psychomotor performance and executive functions showed the most prominent decline. Interestingly, pain duration appeared to be the strongest predictor for observed cognitive decline. Depressive symptoms, sleep disturbance, opioid use and history of alcohol abuse provided additional explanations for the observed cognitive decline in some of the tests, but to a lesser extent than pain duration. The negative effect of pain duration on cognitive performance is compatible with the theory of neurodegenerative properties of chronic pain. Therefore, early and effective therapeutic interventions might reduce or prevent decline in cognitive performance, thereby improving outcomes and quality of life in these patients.

Methods: This was an observational cross-sectional study of 420 older people at two inpatient aged care rehabilitation units. Physical performance was assessed using the Lower Limb Summary Performance Score. Pain was assessed with questions about the extent to which participants were troubled by pain, the duration of symptoms, and the impact of chronic pain on everyday activity. Depression and the number of comorbidities were assessed by questionnaire and medical file audit. Cognition was assessed with the Mini-Mental State Examination.

Full Text Available 32 patients with chronic pelvic pain (CPP were compared with 24 patients with low back pain (LB for the entire course of treatment which lasted 1 year, with follow up at 1,6 and 12 months. At baseline, the group of subjects with CPP presented more hypochondriacal traits, major depression and affective inhibition if compared with LB group, but such psychological variables have not been able to predict the outcome to treatment. No significant difference has been found between LB and CPP subjects regarding the pain threshold of and/or the pain tolerance, when pain was induced by cold stimulation to the hand. High pain tolerance together with the high expectation of analgesia and the conviction of disease appear to be the most important predictors of treatment outcome.

Chronic pain is very common in all European countries, with musculoskeletal problems predominating. About 1% of the adult population develops a syndrome of chronic muscle pain, fibromyalgia (FMS), characterized by multiple tender points, back or neck pain, and a number of associated problems from other organs, including a high frequency of fatigue. Evidence points to central sensitization as an important neurophysiological aberration in the development of FMS. Importantly, these neurological changes may result from inadequately treated chronic focal pain problems such as osteoarthritis or myofascial pain. It is important for health professionals to be aware of this syndrome and to diagnose the patients to avoid a steady increase in diagnostic tests. On the other hand, patients with chronic widespread pain have an increased risk of developing malignancies, and new or changed symptoms should be diagnosed even in FMS. In rheumatology practice it is especially important to be aware of the existence of FMS in association with immune inflammatory diseases, most commonly lupus and rheumatoid arthritis. Differential diagnoses are other causes of chronic pain, e.g. thyroid disease. The costs of this syndrome are substantial due to loss of working capability and direct expenses of medication and health-system usage. Fibromyalgia patients need recognition of their pain syndrome if they are to comply with treatment. Lack of empathy and understanding by healthcare professionals often leads to patient frustration and inappropriate illness behavior, often associated with some exaggeration of symptoms in an effort to gain some legitimacy for their problem. FMS is multifaceted, and treatment consists of both medical interventions, with emphasis on agents acting on the central nervous system, and physical exercises.

All generalist and specialist clinicians are likely to encounter torture survivors among refugees and asylum seekers. A minority of people survive torture and a smaller minority reach a developed country; those who do tend to be the more resilient and resourceful. They have many health, social and welfare problems; persistent pain in the musculoskeletal system is one of the most common. There is little specific evidence on pain in survivors of torture; the guidelines on interdisciplinary specialist management are applicable. Most of the literature on refugee survivors of torture has an exclusive focus on psychological disorders, with particularly poor understanding of pain problems. This article summarizes the current status of assessment and treatment of pain problems in the torture survivor. PMID:25537694
The chronic pain patient with and without chronic opioid medication is at risk for under- and overtreatment perioperatively. Careful planning of the perioperative period by the anesthesiologist, the pain service and the surgeon is crucial. Epidural analgesia requires reduction of preoperative opioid doses to a maximum of 50% to avoid withdrawal as well as continuous postanesthesia care unit-monitoring for the first 24 hours. Brief cognitive behavioral interventions pre- and postoperatively contribute to successful pain management. The perioperative period may be used to re-evaluate the patient's opioid requirements. A follow-up by an experienced pain management service should be available after discharge of the chronic pain patient. Individualized assessment by a pain management team is necessary for this increasing group of patients.

Exercise therapy is the most widely used type of conservative treatment for low back pain. Systematic reviews have shown that exercise therapy is effective for chronic but not for acute low back pain. During the past 5 years, many additional trials have been published on chronic low back pain. This articles aims to give an overview on the effectiveness of exercise therapy in patients with low back pain. For this overview, existing Cochrane reviews for the individual interventions were screened for studies fulfilling the inclusion criteria, and the search strategy outlined by the Cochrane Back Review Group (CBRG) was followed. Studies were included if they fulfilled the following criteria: (1) randomised controlled trials,(2) adult (> or =18 years) population with chronic (> or =12 weeks) nonspecific low back pain and (3) evaluation of at least one of the main clinically relevant outcome measures (pain, functional status, perceived recovery or return to work). Two reviewers independently selected studies and extracted data on study characteristics, risk of bias and outcomes at short-term, intermediate and long-term follow-up. The GRADE approach (GRADE, Grading of Recommendations Assessment, Development and Evaluation) was used to determine the quality of evidence. In total, 37 randomised controlled trials met the inclusion criteria and were included in this overview. Compared to usual care, exercise therapy improved post-treatment pain intensity and disability, and long-term function. The authors conclude that evidence from randomised controlled trials demonstrated that exercise therapy is effective at reducing pain and function in the treatment of chronic low back pain. There is no evidence that one particular type of exercise therapy is clearly more effective than others. However, effects are small and it remains unclear which subgroups of patients benefit most from a specific type of treatment. PMID:20227641

Since the introduction of behavioral medicine in the early 70s, cognitive-behavioral treatment interventions for chronic pain have expanded considerably. It is now well established that these interventions are effective in reducing the enormous suffering that patients with chronic pain have to bear. In addition, these interventions have potential economic benefits in that they appear to be cost-effective as well. Despite these achievements, there is still room for improvement. First, there is a substantial proportion of patients who do not appear to benefit from treatment interventions available. Second, although the effect sizes of most cognitive-behavioral treatments for chronic pain are comparable to those in psychopathology, they are quite modest. Third, there is little evidence for differential outcomes for different treatment methods. Fourth, there still is relatively little known about the specific biobehavioral mechanisms that lead to chronic pain and pain disability. One direction is to better match treatment programs to patients' characteristics. This can be done according to an "Aptitude X Treatment Interaction" framework, or from the perspective of the Moderator-Mediator distinction. In this introduction to the special series on what works for whom in cognitive-behavioral treatments for chronic pain, we review existing knowledge concerning both moderating and mediating variables in cognitive-behavioral treatments for chronic pain. We further argue in favor of theory-driven research as the only way to define specific a priori hypotheses about which patient-treatment interactions to expect. We also argue that replicated single-participant studies, with appropriate statistics, are likely to enhance new developments in this clinical research area.
Full Text Available Rehabilitation of patients with low back pain is very important because the incidence of this symptom is very high among all ages, but especially after forty years. The rehabilitation team must perform a detailed clinical exam and an assessment of the functional limitations and functional goals to achieve at the end of the treatment for every patient. The goals of the therapy are normalization of impairments in flexibility, strength and endurance, and of course, reducing of pain.

Patients with chronic fatigue syndrome (CFS) experience chronic musculoskeletal pain which is even more debilitating than fatigue. Scientific research data gathered around the world enables clinicians to understand, at least in part, chronic musculoskeletal pain in CFS patients. Generalized joint hypermobility and benign joint hypermobility syndrome appear to be highly prevalent among CFS sufferers, but they do not seem to be of any clinical importance. On the other hand, pain catastrophizing accounts for a substantial portion of musculoskeletal pain and is a predictor of exercise performance in CFS patients. The evidence concerning pain catastrophizing is supportive of the indirect evidence of a dysfunctional pain processing system in CFS patients with musculoskeletal pain. CFS sufferers respond to incremental exercise with a lengthened and accentuated oxidative stress response, explaining muscle pain, postexertional malaise, and the decrease in pain threshold following graded exercise in CFS patients. Applying the scientific evidence to the manual physiotherapy profession, pacing self-management techniques and pain neurophysiology education are indicated for the treatment of musculoskeletal pain in CFS patients. Studies examining the effectiveness of these strategies for CFS patients are warranted.

Placebo response in the clinical trial setting is poorly understood and alleged to be driven by statistical confounds, and its biological underpinnings are questioned. Here we identified and validated that clinical placebo response is predictable from resting-state functional magnetic-resonance-imaging (fMRI) brain connectivity. This also led to discovering a brain region predicting active drug response and demonstrating the adverse effect of active drug interfering with placebo analgesia. Chronic knee osteoarthritis (OA) pain patients (n = 56) underwent pretreatment brain scans in two clinical trials. Study 1 (n = 17) was a 2-wk single-blinded placebo pill trial. Study 2 (n = 39) was a 3-mo double-blinded randomized trial comparing placebo pill to duloxetine. Study 3, which was conducted in additional knee OA pain patients (n = 42), was observational. fMRI-derived brain connectivity maps in study 1 were contrasted between placebo responders and nonresponders and compared to healthy controls (n = 20). Study 2 validated the primary biomarker and identified a brain region predicting drug response. In both studies, approximately half of the participants exhibited analgesia with placebo treatment. In study 1, right midfrontal gyrus connectivity best identified placebo responders. In study 2, the same measure identified placebo responders (95% correct) and predicted the magnitude of placebo’s effectiveness. By subtracting away linearly modeled placebo analgesia from duloxetine response, we uncovered in 6/19 participants a tendency of duloxetine enhancing predicted placebo response, while in another 6/19, we uncovered a tendency for duloxetine to diminish it. Moreover, the approach led to discovering that right parahippocampus gyrus connectivity predicts drug analgesia after correcting for modeled placebo-related analgesia. Our evidence is consistent with clinical placebo response having biological underpinnings and shows that the method can also reveal that active

Pain is a primary symptom driving patients to seek physical therapy, and its attenuation commonly defines a successful outcome. A large body of evidence is dedicated to elucidating the relationship between chronic stress and pain; however, stress is rarely addressed in pain rehabilitation. A physiologic stress response may be evoked by fear or perceived threat to safety, status, or well-being and elicits the secretion of sympathetic catecholamines (epinephrine and norepinepherine) and neuroendocrine hormones (cortisol) to promote survival and motivate success. Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also may facilitate the consolidation of fear-based memories for future survival and avoidance of danger. Although short-term stress may be adaptive, maladaptive responses (eg, magnification, rumination, helplessness) to pain or non-pain-related stressors may intensify cortisol secretion and condition a sensitized physiologic stress response that is readily recruited. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain. Stress may be unavoidable in life, and challenges are inherent to success; however, humans have the capability to modify what they perceive as stressful and how they respond to it. Exaggerated psychological responses (eg, catastrophizing) following maladaptive cognitive appraisals of potential stressors as threatening may exacerbate cortisol secretion and facilitate the consolidation of fear-based memories of pain or non-pain-related stressors; however, coping, cognitive reappraisal, or confrontation of stressors may minimize cortisol secretion and prevent chronic, recurrent pain. Given the parallel mechanisms underlying the physiologic effects of a maladaptive response to pain and non-pain-related stressors, physical therapists should consider screening for non-pain-related stress to
Full Text Available Recent investigations of dysfunctional pain processing in the central nervous system have contributed much knowledge about the development of chronic musculoskeletal pain. Many common chronic musculoskeletal pain syndromes - including regional myofascial pain syndromes, whiplash pain syndromes, refractory work-related neck-shoulder pain, certain types of chronic low back pain, fibromyalgia and others - may essentially be explained by abnormalities in central pain modulation. The growing awareness of dysfunctional central pain modulation may be a conceptual breakthrough leading to a better understanding of common chronic pain disorders. A new paradigm will have multiple clinical implications, including re-evaluation of clinical practice routines and rehabilitation methods, and will focus on controversial issues of medicolegal concern. The concept of dysfunctional central pain processing will also necessitate a mechanism-based classification of pain for the selection of individual treatment and rehabilitation programs for subgroups of patients with chronic musculoskeletal pain due to different pathophysiological mechanisms.

The transition from acute pain to chronic pain entails considerable changes of patients at multiple levels of the nervous system and in psychological states. An accurate differentiation between acute and chronic pain is essential in pain management as it may help optimize analgesic treatments according to the pain state of patients. Given that acute and chronic pain could modulate brain states in different ways and that brain states could greatly shape the neural processing of external inputs...

Chronic postsurgical pain (CPSP) is a pain syndrome that has attracted attention for more than 10 years. CPSP is a pain syndrome that develops postoperatively and lasts for at least 2 months in the absence of other causes for pain (eg, recurrence of malignancy, chronic infection, and so forth). Pain continuing from a preexisting disease is not considered as CPSP. In this article, the authors discuss the etiopathogenesis of CPSP and interventions that can help prevent and treat this condition.

BACKGROUND: Catastrophizing plays an important role in models of pain chronicity, showing a consistent correlation with both pain intensity and disability. It is conceivable that these associations are mediated or confounded by other psychological attributes. OBJECTIVE: To examine the relative influence of catastrophizing and other psychological variables on pain and disability in patients with chronic low back pain. METHODS: Seventy-eight patients completed the Pain Catastrophizing Scale, Ro...

Full Text Available Background: Internationally, studies have shown that childhood violence is associated with chronic pain in adulthood. However, to date, this relationship has not been examined in any indigenous population. Objective: The main objectives of this study were to investigate the association between childhood violence and reported chronic pain, number of pain sites and the intensity of pain in adulthood in indigenous Sami and non-Sami adults, and to explore ethnic differences. Design: The study is based on the SAMINOR 2 questionnaire study, a larger population-based, cross-sectional survey on health and living conditions in multiethnic areas with both Sami and non-Sami populations in Mid- and Northern Norway. Our study includes a total of 11,130 adult participants: 2,167 Sami respondents (19.5% and 8,963 non-Sami respondents (80.5%. Chronic pain was estimated by reported pain located in various parts of the body. Childhood violence was measured by reported exposure of emotional, physical and/or sexual violence. Results: Childhood violence was associated with adult chronic pain in several pain sites of the body regardless of ethnicity and gender. Childhood violence was also associated with increased number of chronic pain sites and higher pain intensity compared to those not exposed to childhood violence. However, among Sami men, this association was only significant for pain located in chest, hips/legs and back, and non-significant for increased number of chronic pain sites (adjusted model, and higher pain intensity. Conclusion: Respondents exposed to childhood violence reported more chronic pain in several parts of the body, increased number of chronic pain sites and more intense pain in adulthood than respondents reporting no childhood violence. However, among Sami men, this association was weaker and also not significant for increased number of chronic pain sites and higher pain intensity.
Full Text Available Due to prescribing errors, to wrong therapeutic choice, to inadequate patient education, to errors in patients adherence to therapy, to social problems, to well known comorbidity between chronic pain and depression, a high number of patients, affected by chronic pain becoming acute, is in charge of the Emergency Department. But the Emergency Department is often the wrong place where to take care of such a complex condition. We present the results of a study conducted in our Emergency Department with the contribute of the Mental Health Department, concerning the evaluation of the diagnostic and therapeutic iter, the evolution of the symptoms, the customer satisfaction and the depression comorbidity, among the patients afferent to the Emergency Department because of a chronic non malignant pain becoming acute. The results of the study suggest the necessity of a more specific diagnostic and therapeutic approach to these patients, in both Emergency Hospital Department and outpatients settings.

The growing body of research showing increased opioid use in patients with chronic pain coupled with concerns regarding addiction encouraged the development of this population-based study. The goal of the study was to investigate the co-occurrence of indicators of addictive behaviors in patients...... with chronic non-cancer pain in long-term opioid treatment. The study combined data from the individual-based Danish Health Survey in 2010 and the official Danish health and socio-economic, individual-based registers. From a simple random sample of 25,000 adults (16 years or older) living in Denmark, 13......,281 individuals were analyzed through multiple logistic regression analyses to assess the association between chronic pain (lasting ⩾6 months), opioid use, health behavior, and body mass index. Six potential addictive behaviors were identified: daily smoking; high alcohol intake; illicit drug use in the past year...
Full Text Available The present study aimed at investigating whether chronic pain patients are impaired in Theory of Mind (ToM, or Emotional Awareness.Thirty inpatients suffering from chronic somatoform pain, as well as thirty healthy controls matched for age, sex, and education were recruited. ToM abilities were measured using the Frith-Happé animation task, in which participants interpret video-clips depicting moving geometric forms that mimic social interactions. The responses given were scored for appropriateness and the degree of inferred intentionality according to established protocols. Emotional awareness was measured using the Levels of Emotional Awareness Scale (LEAS, for which participants provide written descriptions of feelings in imaginary emotional situations. Standardized scoring was performed to capture the number and quality of emotional terms used.Responses lengths were similar in both groups and for both tasks. Patients attained significantly lower intentionality but not appropriateness scores when interpreting ToM interactions. No significant group differences were found when interpreting goal directed interactions. Emotional awareness scores were significantly lower in patients compared to healthy controls.Our results suggest that chronic pain patients are impaired in mentalizing and emotional awareness. Future studies are needed to determine whether these ToM and emotional awareness deficits contribute to the etiology of somatoform pain and whether addressing these deficits in therapeutic interventions can improve polymodal pain therapy.

Chronic pelvic pain (CPP) is one of the most common pain conditions affecting women and can have a significant impact on quality of life. Assessment of women with CPP is best approached in a comprehensive, systematic manner that includes exploration of physiological and psychological causes. A range of treatment options that draw from conventional medicine and complementary and alternative modalities should be offered. The women's health nurse plays a pivotal role in all aspects of care.

Because of the great prevalence of chronic pain, it is not surprising that there have been a number of influential reports by the Institute of Medicine, National Institutes of Health, and the World Health Organization that have documented the medical, social and economic problems caused by it, and the need for better pain-management programs. The present article briefly reviews these reports, and then focuses on three important areas that need to be considered when addressing the continuing a...

Exergames are increasingly being proposed for physical rehabilitation in chronic pain. They can be engaging, fun and can facilitate the setting of targets and evaluating performances through body movement tracking and multimodal feedback. While these attributes are important, it is also essential that psychological factors that lead to avoidance of physical activity are addressed in the game design. Anxiety about increased pain and/or of further damage often causes people to behave in a self-...
Full Text Available Many Japanese reports of acupuncture and moxibustion for chronic pain are not listed in medical databases such as Medline. Therefore, they are not easily accessible to researchers outside of Japan. To complement existing reviews of acupuncture and moxibustion for chronic pain and to provide more detailed discussion and analysis, we did a literature search using ‘Igaku Chuo Zasshi Wed’ (Japana Centra Revuo Medicina and ‘Citation Information by National Institute of Information’ covering the period 1978–2006. Original articles and case reports of acupuncture and moxibustion treatment of chronic pain were included. Animal studies, surveys, and news articles were excluded. Two independent reviewers extracted data from located articles in a pre-defined structured way, and assessed the likelihood of causality in each case. We located 57 papers written in Japanese (20 full papers, 37 case reports. Conditions examined were headache (12 trials, chronic low back pain (9 trials, rheumatoid arthritis (8 trials, temporomandibular dysfunction (8 trials, katakori (8 trials and others (12 trials. While 23 were described as clinical control trials (CCTs, 11 employed a quasi-random method. Applying the 5-point Jadad quality assessment scoring system, the mean score was 1.5 ± 1.3 (SD. Eleven (52% of the CCTs were conducted to determine a more effective procedure for acupuncture; these compared a certain type of acupuncture with another type of acupuncture or specific additional points. In particular, the trigger point acupuncture was widely used to treat chronic low back pain in Japan. Many reports of chronic pain treatment by acupuncture and moxibustion are listed in Japanese databases. From the data, we conclude that there is limited evidence that acupuncture is more effective than no treatment, and inconclusive evidence that trigger point acupuncture is more effective than placebo, sham acupuncture or standard care.
Full Text Available Context: Psychological factors, such as that exist when we experience pain, can profoundly alter the strength of pain perception. Aim: The study aims to estimate the prevalence of psychiatric disorders, and its association with perception of pain and functional status in chronic patients in palliative care. Materials and Methods: The sample was selected via simple randomisation and post consent were assessed using (1 a semi- structured questionnaire to elicit socio-demographic information and medical data (2 Brief Pain Inventory (3 ICD-10 Symptom Checklist (4 ICD-10-Diagnostic Criteria for Research (DCR (5 Montgomery Asberg Depression Rating Scale (MADRS (6 Covi Anxiety Rating Scale (7 Karnofsky Performance Status Scale. Data was analysed using independent sample t test and chi square test. Results: The psychiatric morbidity was 67% with depression and adjustment disorders being the major diagnosis. There was a significant association between psychiatric morbidity pain variables (P = 0.000. Psychiatric morbidity significantly impaired activity, mood, working, walk, sleep, relationship, and enjoyment. There was no association between aetiology of pain, type of cancer, treatment for primary condition and treatment for pain and psychiatric morbidity. The functional status of cancer patients was also poorer in patients with psychiatric morbidity (P = 0.008. Conclusion: There is a high prevalence of psychiatric illness in chronic pain patients of any aetiology. Psychiatric morbidity is associated with increased pain perception, impairment in activity and poor functional status.

Full Text Available The prevalence of chronic low back pain presents a world widedilemma to patients, physiotherapists and clinicians. There is scant evidence for prevention and treatment however it is now acknowledged that the use of physiotherapy in a multidimensional context has proved the more appropriate model as a vital component of the collaborative approach required for effective pain management. The following article reviews the current literature, evaluates and combines the guidelines that have been proposed from various international studies to provide a practical approach to the management of chronic back pain. This approach recognizes a broad biopsychosocial model of health and the positive role of activity in health and healing with emphasis on function, rather than impairment. Therefore the development of a patient-centred rehabilitative approach has emerged that emphasizes the restoration of normal movement and function with the addition of physical modalities where appropriate. Recent advances in neurophysiology, the modulation of pain and its perception and the fact that biological systems are known to be greatly affected by electrical treatment provide a clearer rationale for the use of physical agents for rehabilitation of patients with pain and relateddisability. The modalities used in conjunction with active exercises include thermal, massage, electrical stimulation, traction, transcutaneous electrical nerve stimulation (Tens, myofascial release, dry needling, mobilization and acupuncture. An algorithm is provided with the intention of developing protocols for breaking the pain cycle in both nociceptive and neuropathic pain states and in reducing inflammation which is a component of both peripheral and central sensitization. Pain rehabilitation is a useful and cost-effective approach to chronic pain management and makes patients’ responsible partners in their own progress. It encourages planning, pacing of activities and activity related

Theories about the links between traumatization and chronic pain have become the subject of increased interest over the last several years. We will give a short summary about the existing interaction models that emphasize particularly psychological and behavioral aspects of this interaction. After a synopsis of the most important psychoneurobiological mechanisms of pain in the context of traumatization, we introduce the hypermnesia–hyperarousal model, which focuses on two psychoneurobiological aspects of the physiology of learning. This hypothesis provides an answer to the hitherto open question about the origin of pain persistence and pain sensitization following a traumatic event and also provides a straightforward explanatory model for educational purposes.

This study evaluates group treatment for women suffering from chronic pelvic pain. The concept of group treatment was based on psychosomatic and physio-therapeutical principles and on cognitive and operant behavioral therapy. Each group was composed of up to six women suffering from chronic pelvic pain, and two physiotherapists. Each group treatment session lasted 2.5 h per week for a period of 10 weeks. The women completed questionnaires and pain drawings four times during the treatment period from the beginning of the period till 15 months later. During 13 group treatment periods 53 women accomplished the treatment. Before the treatment the women had experienced pain for an average period of 5 years and 9 months (ranging from 6 months to 22 years). The women's descriptions of the changes derived from group treatment were analyzed according to the Grounded Theory Method. A methodical triangulation of quantitative and qualitative data as well as analyzes of the drawings were applied. One year after the end of the treatment, 39% of the women were pain-free. The average level of pain measured according to the Visual Analog Scale was reduced from 2.8 to 0.9 (p Theory Analysis a model of the development process was elaborated. The process begins with the development of self-knowledge, followed by the woman assuming self responsibility for her own life and performing self-activeness. During the process the woman increases her feeling of self-control and personal mastery of her emotions. The women's pain drawings improved, resulting in more detailed drawings, the color intensity abating, the extent of pains declining, and the outlines blurring. In conclusion this kind of group treatment brings the women relief from their pain thus reducing the use of the National Health Service by women suffering from chronic pelvic pain. The women also experience a positive psychological development. This method of treatment, in which a synergetic combination of physical and

Juvenile fibromyalgia in children with sickle cell disease has not been reported in the literature. We report an adolescent patient with sickle cell whose pain symptoms progressed from having recurrent acute sickle cell pain crisis episodes to a chronic pain syndrome over several years. He was eventually diagnosed with juvenile fibromyalgia based on the clinical history and myofascial tender points and his pain symptoms responded better to multidisciplinary strategies for chronic fibromyalgia pain. Chronic pain in sickle cell disease is an area of poor research, and in addition there is inconsistency in the definition of chronic pain in sickle cell disease. Central sensitisation to pain is shown to occur after recurrent painful stimuli in a genetically vulnerable individual. In a chronic pain condition such as fibromyalgia central sensitisation is thought to play a key role. Fibromyalgia should be considered as one of the main differential diagnosis in any sickle cell patient with chronic pain.

[Purpose] The purpose of this study was to examine the influence of mat Pilates and apparatus Pilates on pain and static balance of businesswomen with chronic back pain. [Subjects and Methods] Participants were randomly allocated to Pilates mat exercises (PME) or Pilates apparatus exercise (PAE), and performed the appropriate Pilates exercises 3 days per week for 8 weeks. In order to measure the improvement in the participants' static balance ability as a result of the exercise, the sway length and sway velocity of the subjects were measured before and after the experiment while the subjects stood on a Balance Performance Monitor (BPM) facing the front wall for 30 seconds with their eyes open. The visual analogue scale (VAS) was used to measure the degree of pain. [Results] The VAS score, sway length, and sway velocity of both groups decreased significantly after the experiment, but the PME group showed a greater decrease than the PAE group. [Conclusion] PME showed greater improvement in pain level and balance compared with PAE in this research. Since the subjects of this study were patients with low back pain, PME is assumed to have been more suitable and effective because it uses body weight to strengthen core muscles rather than heavier apparatuses as in PAE.

The classification of most chronic pain disorders gives emphasis to anatomical location of the pain to distinguish one disorder from the other (eg, back pain vs temporomandibular disorder [TMD]) or to define subtypes (eg, TMD myalgia vs arthralgia). However, anatomical criteria overlook etiology, potentially hampering treatment decisions. This study identified clusters of individuals using a comprehensive array of biopsychosocial measures. Data were collected from a case-control study of 1031 chronic TMD cases and 3247 TMD-free controls. Three subgroups were identified using supervised cluster analysis (referred to as the adaptive, pain-sensitive, and global symptoms clusters). Compared with the adaptive cluster, participants in the pain-sensitive cluster showed heightened sensitivity to experimental pain, and participants in the global symptoms cluster showed both greater pain sensitivity and greater psychological distress. Cluster membership was strongly associated with chronic TMD: 91.5% of TMD cases belonged to the pain-sensitive and global symptoms clusters, whereas 41.2% of controls belonged to the adaptive cluster. Temporomandibular disorder cases in the pain-sensitive and global symptoms clusters also showed greater pain intensity, jaw functional limitation, and more comorbid pain conditions. Similar results were obtained when the same methodology was applied to a smaller case-control study consisting of 199 chronic TMD cases and 201 TMD-free controls. During a median 3-year follow-up period of TMD-free individuals, participants in the global symptoms cluster had greater risk of developing first-onset TMD (hazard ratio = 2.8) compared with participants in the other 2 clusters. Cross-cohort predictive modeling was used to demonstrate the reliability of the clusters. PMID:26928952

Full Text Available Abstract Chronic pain in children and adolescents is associated with major disruption to developmental experiences crucial to personal adjustment, quality of life, academic, vocational and social success. Caring for these patients involves understanding cognitive, affective, social and family dynamic factors associated with persistent pain syndromes. Evaluation and treatment necessitate a comprehensive multimodal approach including psychological and behavioral interventions that maximize return to more developmentally appropriate physical, academic and social activities. This article will provide an overview of major psychosocial factors impacting on pediatric pain and disability, propose an explanatory model for conceptualizing the development and maintenance of pain and functional disability in medically difficult-to-explain pain syndromes, and review representative evidence-based cognitive behavioral and systemic treatment approaches for improving functioning in this pediatric population.

Objective The objective of this study was to determine if fixed-site high-frequency transcutaneous electrical nerve stimulation (FS-TENS) is effective in treating chronic low back and lower extremity pain. Background Transcutaneous electrical nerve stimulation is widely used for treatment of chronic pain. General-purpose transcutaneous electrical nerve stimulation devices are designed for stimulation anywhere on the body and often cannot be used while the user is active or sleeping. FS-TENS devices are designed for placement at a pre-determined location, which enables development of a wearable device for use over extended time periods. Methods Study participants with chronic low back and/or lower extremity pain self-administered an FS-TENS device for 60 days. Baseline, 30-, and 60-day follow-up data were obtained through an online questionnaire. The primary outcome measure was the patient global impression of change. Pain intensity and interference were assessed using the Brief Pain Inventory. Changes in use of concomitant pain medications were evaluated with a single-item global self-rating. Results One hundred and thirty participants were enrolled, with 88 completing the 60-day follow-up questionnaire. Most participants (73.9%) were 50 years of age or older. At baseline, low back pain was identified by 85.3%, lower extremity pain by 71.6%, and upper extremity pain by 62.5%. Participants reported widespread pain, at baseline, with a mean of 3.4 (standard deviation 1.1) pain sites. At the 60-day follow-up, 80.7% of participants reported that their chronic pain had improved and they were classified as responders. Baseline characteristics did not differentiate non-responders from responders. There were numerical trends toward reduced pain interference with walking ability and sleep, and greater pain relief in responders. There was a large difference in use of concomitant pain medications, with 80.3% of responders reporting a reduction compared to 11.8% of non

Full Text Available Most pains from the locomotor system arise due to involuntary, chronic tensions in the muscles or other tissues. When the patient is motivated, the pain is easily cured in most of the cases by using the tools of consciousness-based medicine, primarily therapeutic touch, conversation, and coaching the patient in a positive philosophy of life. The pains are often caused by “blockages” that may cause problems other than just pain. Often it turns out that the blocked areas develop actual physical damage over time: a slipped disk in the back, articular degeneration, or osteoarthritis when the cartilage is affected, can often be explained in this way. Apparently, the exact areas where the blockage is situated cause cellular problems, disrupting cellular order. The holistic process theory of healing and the related quality of life theories state that return to the natural state of being is possible, whenever the person gets the resources needed for existential healing. The resources needed are “holding” in the dimensions of awareness, respect, care, acknowledgment, and acceptance with support and processing in the dimensions of feeling, understanding, and letting go of negative attitudes and beliefs. The preconditions for holistic healing are trust and the intention for the healing to take place. Case stories of holistic treatment of patients with chronic back pain, low back pain, muscle problems, knee pain, and symptoms of rheumatoid arthritis are discussed with exercises relevant for patients with these conditions in the holistic clinic.

Background Chronic pain is a common and frequently disabling problem in older adults. Clinical guidelines emphasize the need to use multimodal therapies to manage persistent pain in this population. Pain self-management training is a multimodal therapy that has been found to be effective in young to middle-aged adult samples. This training includes education about pain as well as instruction and practice in several management techniques, including relaxation, physical exercise, modification of negative thoughts, and goal setting. Few studies have examined the effectiveness of this therapy in older adult samples. Methods/Design This is a randomized, controlled trial to assess the effectiveness of a pain self-management training group intervention, as compared with an education-only control condition. Participants are recruited from retirement communities in the Pacific Northwest of the United States and must be 65 years or older and experience persistent, noncancer pain that limits their activities. The primary outcome is physical disability, as measured by the Roland-Morris Disability Questionnaire. Secondary outcomes are depression (Geriatric Depression Scale), pain intensity (Brief Pain Inventory), and pain-related interference with activities (Brief Pain Inventory). Randomization occurs by facility to minimize cross-contamination between groups. The target sample size is 273 enrolled, which assuming a 20% attrition rate at 12 months, will provide us with 84% power to detect a moderate effect size of .50 for the primary outcome. Discussion Few studies have investigated the effects of multimodal pain self-management training among older adults. This randomized controlled trial is designed to assess the efficacy of a pain self-management program that incorporates physical and psychosocial pain coping skills among adults in the mid-old to old-old range.

Pain is one of the most common medical complaints, but despite its prevalence, many individuals still suffer with unrelieved or undertreated pain. This marketing research survey was designed to determine the physical, psychological, and economic impact pain has on the lives of individuals suffering with pain and to identify the unmet needs of patients who have taken opioid medications to treat their pain. In addition, the survey sought to address the challenges physicians face when treating patients with pain. Pain sufferers were recruited through e-mail invitation to an Internet survey; 173,854 invitations were sent out, 22,018 people responded (12.7%), and 606 met the criteria for inclusion in the survey as pain sufferers. Of these, 359 people had moderate to moderately severe chronic pain and 247 people had moderate to moderately severe acute pain. Additionally, physicians currently treating pain were recruited through e-mail and postal mail invitations and 492 met eligibility criteria: 241 specialists (orthopedic or general surgeons, pain specialists or anesthesiologists), 125 primary care, and 126 emergency medicine physicians. Results of this survey supported what many physicians observe in their practice and hear from their patients, that pain has a negative impact on daily activities in the majority of pain sufferers. Many chronic pain sufferers reported that pain had deleterious effects on their mental health, employment status, sleep, and personal relationships. The impact of pain on patient quality of life and the unmet needs in pain management were recognized by the majority of physicians surveyed, with inadequate pain control, end-of-dose pain, and side effects associated with increased dosing reported as negative factors influencing their choice of pain medication. In conclusion, effective communication between physicians and patients is encouraged to not only improve overall pain management but also to establish shared treatment goals with functional

Psychologic variables such as attitudes and beliefs may account for patients choosing not to seek treatment for pain; however, there is a dearth of empirical research to support this contention. The aim of this study was to explore the help-seeking behavior, individual characteristics, attitudes, and beliefs of older adults with chronic pain in an Irish community setting. A descriptive correlational design was used. A convenience sample of 72 older adults with chronic pain were recruited through two primary care practices. The research instruments used were a demographic questionnaire, the Level of Expressed Need Questionnaire, which measured help-seeking behavior, the Pain Attitudes Questionnaire, and the Pain Beliefs Questionnaire. Results revealed that individual characteristics associated with help-seeking behavior were female gender, increasing age, higher education, living alone, and severe pain. High levels of stoicism were reported, indicating that participants were more likely to believe they had superior pain control and courage in the face of pain and were not willing to disclose their pain to others. These attitudes were significantly associated with lower levels of expressed need for treatment. Participants had moderate age-related beliefs about the origin of pain, but those who believed pain had an organic cause were more likely to seek help. PMID:22117752

Full Text Available Abstract Background Many people with chronic nonspecific musculoskeletal pain (CMP have decreased work ability. The majority, however, stays at work despite their pain. Knowledge about workers who stay at work despite chronic pain is limited, narrowing our views on work participation. The aim of this study was to explore why people with CMP stay at work despite pain (motivators and how they manage to maintain working (success factors. Methods A semi-structured interview was conducted among 21 subjects who stay at work despite CMP. Participants were included through purposeful sampling. Interviews were audio-recorded, transcribed verbatim, and imported into computer software Atlas.ti. Data was analyzed by means of thematic analysis. The interviews consisted of open questions such as: "Why are you working with pain?" or "How do you manage working while having pain?" Results A total of 16 motivators and 52 success factors emerged in the interviews. Motivators were categorized into four themes: work as value, work as therapy, work as income generator, and work as responsibility. Success factors were categorized into five themes: personal characteristics, adjustment latitude, coping with pain, use of healthcare services, and pain beliefs. Conclusions Personal characteristics, well-developed self-management skills, and motivation to work may be considered to be important success factors and prerequisites for staying at work, resulting in behaviors promoting staying at work such as: raising adjustment latitude, changing pain-coping strategies, organizing modifications and conditions at work, finding access to healthcare services, and asking for support. Motivators and success factors for staying at work may be used for interventions in rehabilitation and occupational medicine, to prevent absenteeism, or to promote a sustainable return to work. This qualitative study has evoked new hypotheses about staying at work; quantitative studies on staying at
Full Text Available Treatment of chronic pain is challenging. The Arkys project was initiated in Italy to assist general practitioners (GPs in the management of chronic pain. The main objective of this study was to determine the usefulness of Arkys for selecting new therapeutic strategies. An online interactive questionnaire for assessing pain and guiding therapeutic decisions was made available to GPs participating to Arkys. The GPs were invited to complete the questionnaire for each patient who presented moderate-severe chronic pain, and to decide on a new analgesic treatment based on the information provided by the questionnaire. Two hundred and forty four GPs participated with a total of 3035 patients. Patients (mean age 68.9 years had mostly chronic non-cancer pain (87.7%. In 42.3%, pain had neuropathic components. Only 53.6% of patients were in treatment with analgesics (strong opioids, 38.9%; NSAIDs, 32.6%; weak opioids, 25.6%; anti-epileptics, 17.3%; paracetamol, 14.9%. Use of the questionnaire resulted in the prescription of analgesics to all patients and in increased prescription of strong opioids (69.7%. NSAID prescription decreased (12.8%, while anti-epileptics use remained stable. These findings show that current management of chronic pain in primary care is far from optimal and that efforts are needed to educate GPs and improve guideline implementation.

Treatment of chronic pain is challenging. The Arkys project was initiated in Italy to assist general practitioners (GPs) in the management of chronic pain. The main objective of this study was to determine the usefulness of Arkys for selecting new therapeutic strategies. An online interactive questionnaire for assessing pain and guiding therapeutic decisions was made available to GPs participating to Arkys. The GPs were invited to complete the questionnaire for each patient who presented moderate-severe chronic pain, and to decide on a new analgesic treatment based on the information provided by the questionnaire. Two hundred and forty four GPs participated with a total of 3035 patients. Patients (mean age 68.9 years) had mostly chronic non-cancer pain (87.7%). In 42.3%, pain had neuropathic components. Only 53.6% of patients were in treatment with analgesics (strong opioids, 38.9%; NSAIDs, 32.6%; weak opioids, 25.6%; anti-epileptics, 17.3%; paracetamol, 14.9%).

Chronic musculoskeletal pain, such as low back pain, often appears in the presence of psychiatric comorbidities (e.g., depression, posttraumatic stress disorder (PTSD)), especially among U.S. military service members serving in the post-9/11 combat era. Although there has been much speculation about how to best address pain/trauma psychiatric symptom comorbidities, there are little available data to guide practice. The present study sought to examine how pre-treatment depression and PTSD influence outcomes in a functional restoration pain management program using secondary analysis of data from the Department of Defense-funded Functional and Orthopedic Rehabilitation Treatment (FORT) trial. Twenty-eight FORT completers were analyzed using a general linear model exploring how well depression and PTSD symptoms predict post-treatment pain (Visual Analog Scale (VAS) pain rating), disability (Oswestry Disability Index; Million Visual Analog Scale), and functional capacity (Floor-to-Waist and Waist-to-Eye Level progressive isoinertial lifting evaluation scores) in a sample of active duty military members with chronic musculoskeletal pain and comorbid depression or PTSD symptoms. Analysis revealed that pre-treatment depression and PTSD symptoms did not significantly predict rehabilitation outcomes from program completers. Implications of these findings for future research on trauma-related pain comorbidities are discussed. PMID:27417626

Patient characteristics associated with the course and severity of low back pain (LBP) and disability have been the focus of extensive research, however, known characteristics do not explain much of the variance in outcomes. The relationship between anterior trunk pain (ATP) and LBP has not been explored, though mechanisms for visceral referred pain have been described. Study objectives were: (1) determine prevalence of ATP in chronic LBP patients, (2) determine whether ATP is associated with increased pain and disability in these patients, and (3) evaluate whether ATP predicts the course of pain and disability in these patients. In this study, spinal outpatient department patients mapped the distribution of their pain and patients describing pain in their chest, abdomen or groin were classified with ATP. Generalized estimating equations were performed to investigate the relationship between ATP and LBP outcomes. A total of 2974 patients were included and 19.6% of patients reported ATP. At all time points, there were significant differences in absolute pain intensity and disability in those with ATP compared with those without. The presence of ATP did not affect the clinical course of LBP outcomes. The results of this study suggest that patients who present with LBP and ATP have higher pain and disability levels than patients with localised LBP. Visceral referred pain mechanisms may help to explain some of this difference.

Additionally, the role of expectations in treatment outcome was examined. This study also aimed to determine how change in levels of pain, fatigue, disability, and level of interference varied according to the type of treatment delivered to participants.Patients: Forty-seven chronic low back pain patients were recruited from university-affiliated pain clinics.Design: The study design was longitudinal, consisting of two randomly assigned treatment conditions. The first treatment condition used opioid medication only and the second used both opioid medication and brief cognitive behavioral therapy. Pre- and post-treatment assessments were conducted, which occurred approximately 3 months after the initiation of treatment.Outcome measures: A patient-centered outcomes questionnaire was completed by participants at both pre- and post-treatment assessment.Results: Results suggest that patients did not meet their own success criteria in treatment across any of the four domains. There was a significant main effect of time for level of pain indicating that both treatment groups had a decrease in their level of pain at post-treatment, F(1, 45 = 11.98, P < 0.001.

Persons with chronic wounds may experience wound-related itch (pruritus) and pain. A cross-sectional study was conducted to examine the occurrence of itch and pain in chronic wounds and the relationship of the intensity between these factors. Patients in an outpatient wound care center, 18 years and older with an open wound, were recruited consecutively over a 5-month period. The 199 participants (112 [56%] men) had a mean age of 67 years (range 21-98 years); one wound per person was addressed and included venous (31), arterial (23), neuropathic (31), pressure-related (33), traumatic (37), and "other" (41) wounds. Wound-related pain and itch data were obtained using a modified Paul-Pieper Itching Questionnaire and Characteristics of Itch Questionnaire. Responses were hand-recorded and coded without personal identifiers and analyzed using descriptive statistics, and associations among data were assessed using Pearson chi-square, Mantel-Haenszel chi-square, and Cochran-Armitage trend tests. Wound-related itch was significantly associated with participant age (P = 0.011) and employment status (P = 0.003). Wound-related pain was significantly associated only with education level (P = 0.048). Persons with venous wounds had both the largest proportion with wound-related itch (45.2%) and the largest proportion with wound-related pain (61.2%) out of all of the wound types. Persons with diabetic neuropathy had both the smallest proportion with wound-related itch (16.1%) and the smallest proportion with wound-related pain (35.4%) among all of the wound types. Associations between wound type and wound-related itch or pain were not significant. When venous wounds were compared to all other wound types combined, wound-related itch was significantly associated (P = 0.021) with wound type - ie, venous wound type and itch was statistically significant when venous wounds were compared to a combination of all other wound types. Wound-related pain and itch occurred together in 35

Combined pharmacological treatments are the most used approach for neuropathic pain. Carbamazepine, an antiepileptic agent, is generally used as a third-line treatment for neuropathic pain and can be considered an option only when patients have not responded to the first- and second-line medications. In the case presented herein, a patient with neuropathic pain was treated using a combined pharmacological regimen. The patient's pain deteriorated, despite increasing the doses of opioids, when carbamazepine was discontinued, potentially because carbamazepine withdrawal disrupted the balance that was achieved by the multifaceted pharmacological regimen, thus inducing hyperalgesia. Interestingly, when carbamazepine was prescribed again, the patient's pain was successfully managed. Animal research has reported that carbamazepine can potentiate the analgesic effectiveness of morphine in rodent models of neuropathic pain and postoperative pain. This clinical case demonstrates that carbamazepine may have a synergistic effect on the analgesic effectiveness of morphine and may inhibit or postpone opioid-induced hyperalgesia. We postulate that a probable mechanism of action of carbamazepine may involve -aminobutyric acid-ergic potentiation and the interruption of glutamatergic function via N-methyl-D-aspartate receptors. Further research is warranted to clarify the analgesic action of carbamazepine and its potential use for the prevention of opioid-induced hyperalgesia in chronic neuropathic pain patients.

This study reviewed the published literature evaluating multidisciplinary chronic pain treatment facilities to provide an overview of their availability, caseload, wait times, and facility characteristics. A systematic literature review was conducted using PRISMA guidelines following a search of MEDLINE, PsycINFO, and CINAHL databases. Inclusion criteria stipulated that studies be original research, survey more than one pain treatment facility directly, and describe a range of available treatments. Fourteen articles satisfied inclusion criteria. Results showed little consistency in the research design used to describe pain treatment facilities. Availability of pain treatment facilities was scarce and the reported caseloads and wait times were generally high. A wide range of medical, physical, and psychological pain treatments were available. Most studies reported findings on the percentage of practitioners in different health care professions employed. Future studies should consider using more comprehensive search strategies to survey facilities, improving clarity on what is considered to be a pain treatment facility, and reporting on a consistent set of variables to provide a clear summary of the status of pain treatment facilities. This review highlights important information for policymakers on the scope, demand, and accessibility of pain treatment facilities. PMID:27445618

Full Text Available One in five Canadians suffers from some form of persistent or chronic pain. The impact on individual lives, families and friends, the health services sector and the economy is huge. Reliable evidence is available that the burden of persistent pain can be markedly reduced when available knowledge is applied. Bridging the quality chasm between chronic pain and the care process will require a unique confluence of opinion from all stakeholders committed within a focused community of practice to address the impact of pain. Various levels of success in this regard have been demonstrated when there is exchange, synthesis and ethically sound application of research findings within a complex set of interactions among researchers and knowledge users. It is now critical to accelerate the capture of the benefits of research for Canadians through improved health, more effective and responsive services and products, and a strengthened health care system to bring about health reform and health care reform across Canada as it pertains to the one in five Canadians living with chronic, disabling pain. The overarching outcome of such an initiative needs to be promoted to sustain a balanced portfolio of curiosity-and needs-based research, which along with existing knowledge, can be mobilized and applied for the benefit of Canadians, the health care system and the economy.
The prevalence of chronic widespread pain in the general population in Israel was comparable with reports from the USA, UK, and Canada. Comorbidity with fibromyalgia (FM) resulted in somatic hyperalgesia in patients with irritable bowel syndrome. One sixth of the subjects with chronic widespread pain in the general population were also found to have a mental disorder. Mechanisms involved in referred pain, temporal summation, muscle hyperalgesia, and muscle pain at rest were attenuated by the N-methyl-D-aspartate (NMDA) antagonist, ketamine, in FM patients. Delayed corticotropin release, after interleukin-6 administration, in FM was shown to be consistent with a defect in hypothalamic corticotropin-releasing hormone neural function. The basal autonomic state of FM patients was characterized by increased sympathetic and decreased parasympathetic systems tones. The severity of functional impairment as assessed by the Medical Outcome Survey Short Form (SF-36) discriminated between patients with widespread pain alone and FM patients. Chronic fatigue syndrome (CFS) occurred in about 0.42% of a random community-based sample of 28,673 adults in Chicago, Illinois. A significant clinical overlap between CFS and FM was reported. Cytokine dysregulation was not found to be a singular or dominant factor in the pathogenesis of CFS. A favorable outcome of CFS in children was reported; two thirds recovered and resumed normal activities. No major therapeutic trials in FM and CFS were reported over the past year.

Full Text Available Objectives. This study was done to evaluate three bedside tests in discriminating visceral pain from somatic pain among women with chronic pelvic pain. Study Design. The study was an exploratory cross-sectional evaluation of 81 women with chronic pelvic pain of 6 or more months' duration. Tests included abdominal cutaneous allodynia (aCA, perineal cutaneous allodynia (pCA, abdominal and perineal myofascial trigger points (aMFTP and (pMFTP, and reduced pain thresholds (RPTs. Results. Eighty-one women were recruited, and all women provided informed consent. There were 62 women with apparent visceral pain and 19 with apparent somatic sources of pain. The positive predictive values for pelvic visceral disease were aCA-93%, pCA-91%, aMFTP-93%, pMFTP-81%, and RPT-79%. The likelihood ratio (+ and 95% C.I. for the detection of visceral sources of pain were aCA-4.19 (1.46, 12.0, pCA-2.91 (1.19, 7.11, aMTRP-4.19 (1.46, 12.0, pMFTP-1.35 (0.86, 2.13, and RPT-1.14 (0.85, 1.52, respectively. Conclusions. Tests of cutaneous allodynia, myofascial trigger points, and reduced pain thresholds are easily applied and well tolerated. The tests for cutaneous allodynia appear to have the greatest likelihood of identifying a visceral source of pain compared to somatic sources of pain.

Chronic groin pain is one the most complex conditions encountered in the field of sports medicine. Conservative treatment is long lasting and the result of treatment is often uncer- tain and symptom recurrences are common, which can be very frustrating for both the patient and the physician. The complex etiology and uncertainties during treatment of chronic groin pain is the reason why some authors call it the Bermuda Triangle of sports medicine. In our prospective, 7-year study, 114 athletes with chronic groin pain resistant to conservative therapy were treated surgically. In 109 athletes with sports hernia, we performed nerve neurolysis along with resection of the genital branch of the genitofemoral nerve and we also reinforced the posterior wall of inguinal canal using a modified Shouldice technique. In 26 athletes that had concomitant adductor tendinosis and in 5 athletes with isolated tendinosis we performed tenotomy. Eighty-one of 83 patients with isolated sports hernia returned to sports within a mean of 4.4 (range, 3-16) weeks. Thirty-one athletes with adductor tenotomy returned to sports activity within a mean of 11.8 (range, 10-15) weeks. If carefully diagnosed using detailed history taking, physical examination and correct imaging techniques, chronic groin pain can be treated very successfully and quickly, so it need not be a Bermuda Triangle of sports medicine.

Objectives: With growing evidence for the effectiveness of craniosacral therapy (CST) for pain management, the efficacy of CST remains unclear. This study therefore aimed at investigating CST in comparison with sham treatment in chronic nonspecific neck pain patients. Materials and Methods: A total of 54 blinded patients were randomized into either 8 weekly units of CST or light-touch sham treatment. Outcomes were assessed before and after treatment (week 8) and again 3 months later (week 20). The primary outcome was the pain intensity on a visual analog scale at week 8; secondary outcomes included pain on movement, pressure pain sensitivity, functional disability, health-related quality of life, well-being, anxiety, depression, stress perception, pain acceptance, body awareness, patients’ global impression of improvement, and safety. Results: In comparison with sham, CST patients reported significant and clinically relevant effects on pain intensity at week 8 (−21 mm group difference; 95% confidence interval, −32.6 to −9.4; P=0.001; d=1.02) and at week 20 (−16.8 mm group difference; 95% confidence interval, −27.5 to −6.1; P=0.003; d=0.88). Minimal clinically important differences in pain intensity at week 20 were reported by 78% within the CST group, whereas 48% even had substantial clinical benefit. Significant between-group differences at week 20 were also found for pain on movement, functional disability, physical quality of life, anxiety and patients’ global improvement. Pressure pain sensitivity and body awareness were significantly improved only at week 8. No serious adverse events were reported. Discussion: CST was both specifically effective and safe in reducing neck pain intensity and may improve functional disability and the quality of life up to 3 months after intervention. PMID:26340656

The aim of the study was to show the role of tools in the evaluation of chronic pain (CP) in general practitioner (GP) everyday clinical practice. The study was done by analyzing electronic database of the first visits of 1090 CP patients referred to the Pain Clinic of the Karlovac General Hospital, Karlovac, Croatia, by their GPs. All patient records were analyzed according to the cause of CP, strongest pain a week before the examination, quality of sleep, and the Patients' Global Impression of Change scale. All statistical analyses were done using the IBM SPSS Statistics version 220.127.116.11 (www.spss.com). CP predominantly occurs in older age group. Patients with musculoskeletal pain accounted for the highest percentage (n = 316; 29%), followed by those with neuropathic pain (n = 253; 23.20%) and those with low back pain (n = 225; 20.60%). The mean pain intensity rating scale score was 8.3 ± 1.8 a week before the examination and the mean quality of sleep score was 6.8 ± 1.9. Moderate and severe sleep quality disorder was significantly present in patients over 65 years of age (p = 0.007), patients with musculoskeletal and neuropathic pain, back pain, and those having rated Patients' Global Impression of Change scale as worsening (p = 0.001). The severity of pain and poor quality of sleep are the leading causes of deterioration of the Patients' Global Impression of Change scale in patients suffering from musculoskeletal and neuropathic pain. In order to treat CP comprehensively, it is important for GPs to evaluate the outcomes of clinical treatment using tools for CP assessment. PMID:27276768

This study aimed to analyze the experience of working women suffering from chronic musculoskeletal pain, using a qualitative design with a phenomenological approach. The technique drew on in-depth interviews with five working women that presented to the orthopedics and neurosurgery departments of a hospital in Guadalajara, Mexico, with a complaint of musculoskeletal pain for more than six months. The study showed that the women felt rejection, segregation, discrimination, lack of support at the workplace, and feelings of frustration and powerlessness related to their health condition. The women also perceived as a barrier the lack of efficiency in disability proceedings and job reintegration or relocation. Financial and family responsibilities were their main reason for continuing to work despite their chronic musculoskeletal pain. PMID:26735388
Full Text Available Holistic medicine seems to be efficient in the treatment of chronic pain in internal organs, especially when the pain has no known cause. It is quite surprising that while chronic pain can be one of the toughest challenges in the biomedical clinic, it is often one of the simplest things to alleviate in the holistic clinic. These pains are regarded as being caused by repressed emotions and are explained as psychosomatic reactions. Using holistic medicine, the patients can often be cured of their suffering when they assume responsibility for the repressed feelings. The holistic process theory of healing states that the return to the natural (pain free state of being is possible whenever the person obtains the resources needed for existential healing. This shift is explained by the related quality of life and life mission theories. The resources needed are “holding” or genuine care in the dimensions of awareness, respect, care, acknowledgment, and acceptance with support and processing in the dimensions of feeling, understanding, and letting go of negative attitudes and beliefs. The preconditions for the holistic healing to take place are “love” and trust. Obtaining the full trust of the patient, therefore, seems to be the biggest challenge of holistic medicine, especially when dealing with a patient in pain.

In a trial comparing yoga to intensive stretching and self-care, we explored whether physical (hours of back exercise/week, cognitive (fear avoidance, body awareness, and self-efficacy, affective (psychological distress, perceived stress, positive states of mind, and sleep, and physiological factors (cortisol, DHEA mediated the effects of yoga or stretching on back-related dysfunction (Roland-Morris Disability Scale (RDQ. For yoga, 36% of the effect on 12-week RDQ was mediated by increased self-efficacy, 18% by sleep disturbance, 9% by hours of back exercise, and 61% by the best combination of all possible mediators (6 mediators. For stretching, 23% of the effect was mediated by increased self-efficacy, 14% by days of back exercise, and 50% by the best combination of all possible mediators (7 mediators. In open-ended questions, ≥20% of participants noted the following treatment benefits: learning new exercises (both groups, relaxation, increased awareness, and the benefits of breathing (yoga, benefits of regular practice (stretching. Although both self-efficacy and hours of back exercise were the strongest mediators for each intervention, compared to self-care, qualitative data suggest that they may exert their benefits through partially distinct mechanisms.

This systematic review addresses the pathophysiology, diagnostic evaluation, and treatment of several chronic pain syndromes affecting the pelvic organs: chronic proctalgia, coccygodynia, pudendal neuralgia, and chronic pelvic pain. Chronic or recurrent pain in the anal canal, rectum, or other pelvic organs occurs in 7% to 24% of the population and is associated with impaired quality of life and high health care costs. However, these pain syndromes are poorly understood, with little research evidence available to guide their diagnosis and treatment. This situation appears to be changing: A recently published large randomized, controlled trial by our group comparing biofeedback, electrogalvanic stimulation, and massage for the treatment of chronic proctalgia has shown success rates of 85% for biofeedback when patients are selected based on physical examination evidence of tenderness in response to traction on the levator ani muscle-a physical sign suggestive of striated muscle tension. Excessive tension (spasm) in the striated muscles of the pelvic floor appears to be common to most of the pelvic pain syndromes. This suggests the possibility that similar approaches to diagnostic assessment and treatment may improve outcomes in other pelvic pain disorders.

Depression and chronic pain know no geographical boundaries. About 350 million people around the world experience long-lasting sadness and an unshakeable sense of hopelessness, and one person out of ten tries to live each day to its fullest despite continuous physical pain. These two difficult conditions frequently coexist, becoming more common with age. Looking ahead, we can expect the incidence of depression and chronic illness to grow, since more people over age 65 will populate the world by 2020 than children younger than five. PMID:25782107

The purpose of this study was to report sleep quality from 4 weeks of auricular point acupressure that was designed for chronic low back pain and determine the relationship between pain intensity and sleep quality. Participants were randomized into the APA group (n = 30) or the sham-APA group (n = 31). At baseline assessment, 87% of the participants reported poor sleep quality. Participants who received APA had decreased daytime disturbance and improved global Pittsburgh Sleep Quality Index scores at end of intervention (EOI) and 1-month follow up compared to participants in the sham-APA group. For the APA group, both the sleep duration and wake after sleep onset decreased gradually during the 4-week APA (0.56% and 0.23% daily change, respectively). PMID:26244591

It is now feasible to adopt an evidence-based approach when providing physical treatment for patients with chronic LBP. A summary of the efficacy of a range of physical treatments is provided in Table 1. The evidence-based primary care options are exercise, laser, massage, and spinal manipulation; however, the latter three have small or transient effects that limit their value as therapies for chronic LBP. In contrast, exercise produces large reductions in pain and disability, a feature that suggests that exercise should play a major role in the management of chronic LBP. Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered. Outside of primary care, multidisciplinary treatment or functional restoration is effective; however, the high cost probably means that these programs should be reserved for patients who do not respond to cheaper treatment options for chronic LBP. Although there are now effective treatment options for chronic LBP, it needs to be acknowledged that the problem of chronic LBP is far from solved. Though treatments can provide marked improvements in the patient's condition, the available evidence suggests that the typical chronic LBP patient is left with some residual pain and disability. Developing new, more powerful treatments and refining the current group of known effective treatments is the challenge for the future. PMID:15062718
Full Text Available Objectives. The objective of this one-group, repeated-measures design was to explore the acceptance of auricular point acupressure (APA to reduce chronic low back pain (CLBP and estimate minimum clinically important differences (MCIDs for pain intensity change. Methods. Subjects received 7-day APA treatment. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point for 7-day. The Brief Pain Inventory Short Form (BPI was used to collect outcome data. Results. A total of 74 subjects participated in the study. Ten subjects dropped out and the retention rate was 87%. Subjects reported a 46% reduction in BPI worst pain, and over 50% reduction in BPI average pain, overall pain severity and pain interference by the end of study, and 62.5% subjects also reported less pain medication use. The MCIDs for the subscale of BPI ranged from .70 to 1.86 points. The percentage improvement of MCIDs from baseline was between 14.5–24.9%. Discussion. APA appears to be highly acceptable to patients with CLBP. A sham group is needed in order to differentiate the true effects of APA from the possible psychological effects of more frequent visits by the auricular therapist and patients’ expectation of the APA treatment.

The therapeutic model underlying Acceptance and Commitment Therapy (ACT) is reasonably well-established as it applies to chronic pain. Several studies have examined measures of single ACT processes, or subsets of processes, and have almost uniformly indicated reliable relations with patient functioning. To date, however, no study has performed a comprehensive examination of the entire ACT model, including all of its component processes, as it relates to functioning. The present study performed this examination in 274 individuals with chronic pain presenting for an assessment appointment. Participants completed a battery of self-report questionnaires, assessing multiple aspects of the ACT model, as well as pain intensity, disability, and emotional distress. Initial exploratory factor analyses examined measures of the ACT model and measures of patient functioning separately with each analysis identifying three factors. Next, the fit of a model including ACT processes on the one hand and patient functioning on the other was examined using Structural Equation Modeling. Overall model fit was acceptable and indicated moderate correlations among the ACT processes themselves, as well as significant relations with pain intensity, emotional distress, and disability. These analyses build on the existing literature by providing, to our knowledge, the most comprehensive evaluation of the ACT theoretical model in chronic pain to date.

Chronic musculoskeletal pain is a significant health problem and is associated with increases in pain during acute physical activity. Regular physical activity is protective against many chronic diseases; however, it is unknown if it plays a role in development of chronic pain. The current study induced physical activity by placing running wheels in home cages of mice for 5 days or 8 wk and compared these to sedentary mice without running wheels in their home cages. Chronic muscle pain was in...

Gabapentin is prescribed for analgesia in chronic low back pain, yet there are no controlled trials supporting this practice. This randomized, 2-arm, 12-week, parallel group study compared gabapentin (forced titration up to 3600 mg daily) with inert placebo. The primary efficacy measure was change in pain intensity from baseline to the last week on treatment measured by the Descriptor Differential Scale; the secondary outcome was disability (Oswestry Disability Index). The intention-to-treat analysis comprised 108 randomized patients with chronic back pain (daily pain for ≥6 months) whose pain did (43%) or did not radiate into the lower extremity. Random effects regression models which did not impute missing scores were used to analyze outcome data. Pain intensity decreased significantly over time (P pain intensity, or at least "Minimal Improvement" on the Physician Clinical Global Impression of Change did not differ significantly between groups. There were no significant differences in analgesia between participants with radiating (n = 46) and nonradiating (n = 62) pain either within or between treatment arms. There was no significant correlation between gabapentin plasma concentration and pain intensity. Gabapentin appears to be ineffective for analgesia in chronic low back pain with or without a radiating component. PMID:26963844

Full Text Available Central sensitivity syndromes (CSS include fibromyalgia syndrome (FMS, irritable bowel syndrome, temporomandibular disorder, restless legs syndrome, chronic fatigue syndrome, and other similar chronic painful conditions that are based on central sensitization (CS. CSS are mutually associated. In this paper, prevalence of FMS among other members of CSS has been described. An important recent recognition is an increased prevalence of FMS in other chronic pain conditions with structural pathology, for example, rheumatoid arthritis, systemic lupus, ankylosing spondylitis, osteoarthritis, diabetes mellitus, and inflammatory bowel disease. Diagnosis and proper management of FMS among these diseases are of crucial importance so that unwarranted use of such medications as corticosteroids can be avoided, since FMS often occurs when RA or SLE is relatively mild.

Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.
Full Text Available Abstract Background Prevalence of pain as a recurrent symptom in children is known to be high, but little is known about children with high impairment from chronic pain seeking specialized treatment. The purpose of this study was the precise description of children with high impairment from chronic pain referred to the German Paediatric Pain Centre over a 5-year period. Methods Demographic variables, pain characteristics and psychometric measures were assessed at the first evaluation. Subgroup analysis for sex, age and pain location was conducted and multivariate logistic regression applied to identify parameters associated with extremely high impairment. Results The retrospective study consisted of 2249 children assessed at the first evaluation. Tension type headache (48%, migraine (43% and functional abdominal pain (11% were the most common diagnoses with a high rate of co-occurrence; 18% had some form of musculoskeletal pain disease. Irrespective of pain location, chronic pain disorder with somatic and psychological factors was diagnosed frequently (43%. 55% of the children suffered from more than one distinct pain diagnosis. Clinically significant depression and general anxiety scores were expressed by 24% and 19% of the patients, respectively. Girls over the age of 13 were more likely to seek tertiary treatment compared to boys. Nearly half of children suffered from daily or constant pain with a mean pain value of 6/10. Extremely high pain-related impairment, operationalized as a comprehensive measure of pain duration, frequency, intensity, pain-related school absence and disability, was associated with older age, multiple locations of pain, increased depression and prior hospital stays. 43% of the children taking analgesics had no indication for pharmacological treatment. Conclusion Children with chronic pain are a diagnostic and therapeutic challenge as they often have two or more different pain diagnoses, are prone to misuse of

In line with growing evidence of the health benefits of singing, this study aimed to explore participants' perceptions of the impact of a service-user-led community pain choir on their psychological wellbeing, self-efficacy and relationships with their chronic pain. The choir has links to a multidisciplinary pain management service, which is informed by the ethos of solution-focused (SF) principles, specifically in identifying and drawing upon patients' resources. Seven choir members participated in semi-structured interviews, grounded in lines of enquiry commonly used in SF practice. Thematic analysis of the data uncovered seven themes: Physical Improvements, Emotional Impact, Personal Growth, Interpersonal Processes, Relationship with the 'Self', Living Well with Pain and Sharing the Music and Spreading the Word. Participants' narratives provided support for participation in the choir in enhancing positive affect, self-worth, interpersonal relationships and overall wellbeing. The choir enabled continued progress towards accomplishing key pain management programme aims: self-management, coping and living well with pain. Findings expanded upon existing evidence relating to singing and wellbeing by highlighting the choir's role in promoting resilience and acceptance of pain. Clinical implications are explored in relation to psychosocial dimensions of pain. PMID:27583139

The objectives of this study were to explore the existence of subgroups in a cohort with chronic low back pain (n = 294) based on the results of multimodal sensory testing and profile subgroups on demographic, psychological, lifestyle, and general health factors. Bedside (2-point discrimination, brush, vibration and pinprick perception, temporal summation on repeated monofilament stimulation) and laboratory (mechanical detection threshold, pressure, heat and cold pain thresholds, conditioned pain modulation) sensory testing were examined at wrist and lumbar sites. Data were entered into principal component analysis, and 5 component scores were entered into latent class analysis. Three clusters, with different sensory characteristics, were derived. Cluster 1 (31.9%) was characterised by average to high temperature and pressure pain sensitivity. Cluster 2 (52.0%) was characterised by average to high pressure pain sensitivity. Cluster 3 (16.0%) was characterised by low temperature and pressure pain sensitivity. Temporal summation occurred significantly more frequently in cluster 1. Subgroups were profiled on pain intensity, disability, depression, anxiety, stress, life events, fear avoidance, catastrophizing, perception of the low back region, comorbidities, body mass index, multiple pain sites, sleep, and activity levels. Clusters 1 and 2 had a significantly greater proportion of female participants and higher depression and sleep disturbance scores than cluster 3. The proportion of participants undertaking <300 minutes per week of moderate activity was significantly greater in cluster 1 than in clusters 2 and 3. Low back pain, therefore, does not appear to be homogeneous. Pain mechanisms relating to presentations of each subgroup were postulated. Future research may investigate prognoses and interventions tailored towards these subgroups. PMID:26020225

Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (ie, chronic postsurgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (ie, surgery, viral infection, injury, and toxic or noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.
Measuring disability is an important topic in rehabilitation research in patients with chronic low back pain (CLBP). Due to the major impact of CLBP on functioning in both daily living and work, measuring disability in patients with CLBP is best described in terms of limitations in activities and restrictions in participation in daily living and work. A frequently used measurement instrument in rehabilitation medicine to measure self-reported limitations in activities of daily living (ADL) in...

Full Text Available INTRODUCTION: Chronic pain is a significant health problem worldwide, with a prevalence in the general population of approximately 40%. Alexithymia -- the personality trait of having difficulties with emotional awareness and self-regulation -- has been reported to contribute to an increased risk of several chronic diseases and health conditions, and limited research indicates a potential role for alexithymia in the development and maintenance of chronic pain. However, no study has yet examined the associations between alexithymia and chronic pain in the general population. METHODS: We administered measures assessing alexithymia, pain, disability, anxiety, depression, and life satisfaction to 927 adults in Hisayama, Japan. We classified the participants into four groups (low-normal alexithymia, middle-normal alexithymia, high-normal alexithymia, and alexithymic based on their responses to the alexithymia measure. We calculated the risk estimates for the criterion measures by a logistic regression analysis. RESULTS: Controlling for demographic variables, the odds ratio (OR for having chronic pain was significantly higher in the high-normal (OR: 1.49, 95% CI: 1.07-2.09 and alexithymic groups (OR: 2.56, 95% CI: 1.47-4.45 compared to the low-normal group. Approximately 40% of the participants belonged to these two high-risk groups. In the subanalyses of the 439 participants with chronic pain, the levels of pain intensity, disability, depression, and anxiety were significantly increased and the degree of life satisfaction was decreased with elevating alexithymia categories. CONCLUSIONS: The findings demonstrate that, in the general population, higher levels of alexithymia are associated with a higher risk of having chronic pain. The early identification and treatment of alexithymia and negative affect may be beneficial in preventing chronic pain and reducing the clinical and economic burdens of chronic pain. Further research is needed to
Background. In order to better design awareness programs on chronic pain (CP), measurement of knowledge, beliefs, and attitudes of people in the community towards this condition is most useful. Objectives. To develop and validate a French-Canadian scale that could be used for this purpose. Methods. Items of the Chronic Pain Myth Scale (CPMS) were developed based on different information sources, reviewed by pain experts, and pretested. The CPMS was administered to 1555 participants among the general Quebec population. Results. The final CPMS contained 26 items allowing the calculation of three subscales scores (knowledge, beliefs, and attitudes towards people suffering from CP, biopsychosocial impacts of CP, and treatment of CP) which showed adequate internal consistency (α = 0.72–0.82). There were statistically significant differences in subscales scores between participants who reported suffering versus not suffering from CP, reported knowing versus not knowing someone who suffers from CP, and reported being versus not being a healthcare professional, which supports the construct validity of the scale. Conclusions. Our results provide preliminary evidence supporting the psychometric qualities of the use of the CPMS for the measurement of knowledge, beliefs, and attitudes towards CP among French-speaking individuals of the Quebec general population.

Full Text Available Abstract Background Chronic musculoskeletal pain is common and has been increasingly managed by opioid medications, of which the long-term efficacy is unknown. Furthermore, there is evidence that long-term use of opioids is associated with reduced pain control, declining physical function and quality of life, and could hinder the goals of integrated pain management. Electroacupuncture (EA has been shown to be effective in reducing postoperative opioid consumption. Limited evidence suggests that acupuncture could assist patients with chronic pain to reduce their requirements for opioids. The proposed research aims to assess if EA is an effective adjunct therapy to standard pain and medication management in reducing opioids use by patients with chronic musculoskeletal pain. Methods In this multicentre, randomised, sham-acupuncture controlled, three-arm clinical trial, 316 patients regularly taking opioids for pain control and meeting the defined selection criteria will be recruited from pain management centres and clinics of primary care providers in Victoria, Australia. After a four-week run-in period, the participants are randomly assigned to one of three treatment groups to receive EA, sham EA or no-EA with a ratio of 2:1:1. All participants receive routine pain medication management delivered and supervised by the trial medical doctors. Twelve sessions of semi-structured EA or sham EA treatment are delivered over 10 weeks. Upon completion of the acupuncture treatment period, there is a 12-week follow-up. In total, participants are involved in the trial for 26 weeks. Outcome measures of opioid and non-opioid medication consumption, pain scores and opioid-related adverse events are documented throughout the study. Quality of life, depression, function, and attitude to pain medications are also assessed. Discussion This randomised controlled trial will determine whether EA is of significant clinical value in assisting the management of

Patients with chronic pain due to neuropathy or musculoskeletal injury frequently exhibit reduced alpha and increased theta power densities. However, little is known about electrical brain activity and chronic pain in patients with rheumatoid arthritis (RA). For this purpose, we evaluated power densities of spontaneous electroencephalogram (EEG) band frequencies (delta, theta, alpha, and beta) in females with persistent pain due to RA. This was a cross-sectional study of 21 participants with RA and 21 healthy controls (mean age = 47.20; SD = 10.40). EEG was recorded at rest over 5 min with participant's eyes closed. Twenty electrodes were placed over five brain regions (frontal, central, parietal, temporal, and occipital). Significant differences were observed in depression and anxiety with higher scores in RA participants than healthy controls (p = 0.002). Participants with RA exhibited increased average absolute alpha power density in all brain regions when compared to controls [F(1.39) = 6.39, p = 0.016], as well as increased average relative alpha power density [F(1.39) = 5.82, p = 0.021] in all regions, except the frontal region, controlling for depression/anxiety. Absolute theta power density also increased in the frontal, central, and parietal regions for participants with RA when compared to controls [F(1, 39) = 4.51, p = 0.040], controlling for depression/anxiety. Differences were not exhibited on beta and delta absolute and relative power densities. The diffuse increased alpha may suggest a possible neurogenic mechanism for chronic pain in individuals with RA. PMID:27540360

Chronic pelvic pain is common, but rarely cured, thus patients seek both second opinions and alternative means of controlling their pain. Complementary and alternative medicine accounts for 11.2% of out-of-pocket medical expenditures for adults for all conditions in the United States. Although there are many treatments, rigorous testing and well-done randomized studies are lacking. Dietary changes and physical modalities such as physical therapy have often been included in the category of alternative medicine, but their use is now considered mainstream. This article concentrates on other sources of alternative and complementary medicine, such as dietary supplementation and acupuncture.

The aim of this study was to systematically review available evidence on the prevalence and severity of pain in adult end-stage renal disease patients on chronic intermittent HD. Materials and methods: We carried out a systematic review of the literature and developed a comprehensive search strategy based on search terms on pain and HD. We searched the databases MEDLINE, Scopus, PsycINFO, and CINAHL from the earliest date of each database to July 24, 2014. Manuscripts in all languages were taken into consideration. Two authors performed each step independently, and all disagreements were resolved after discussion with the third author. The quality of studies was estimated using the STROBE checklist and Cochrane risk-of-bias tool.Results: We included 52 studies with 6,917 participants. The prevalence of acute and chronic pain in HD patients was up to 82% and 92%, respectively. A considerable number of patients suffered from severe pain. Various locations and causes of pain were described, with most of the studies reporting pain in general, pain related to arteriovenous access, headache, and musculoskeletal pain.Conclusion: The findings of this systematic review indicate high prevalence of pain in HD patients and considerable gaps and limitations in the available evidence. Pain in this population should be recognized as a considerable health concern, and the nephrology community should promote pain management in HD patients as a clinical and research priority to improve patients’ quality of life and pain

As in the general population, chronic pain is a prevalent and burdensome affliction in active-duty military personnel. Painful conditions in military members can be categorized broadly in terms of whether they arise directly from combat injuries (gunshot, fragmentation wound, blast impact) or whether they result from non-combat injuries (sprains, herniated discs, motor vehicle accidents). Both combat-related and non-combat-related causes of pain can further be classified as either acute or chronic. Here we discuss the state of pain management as it relates to the military population in both deployed and non-deployed settings. The term non-battle injury (NBI) is commonly used to refer to those conditions not directly associated with the combat actions of war. In the history of warfare, NBI have far outstripped battle-related injuries in terms not only of morbidity, but also mortality. It was not until improvements in health care and field medicine were applied in World War I that battle-related deaths finally outnumbered those attributed to disease and pestilence. However, NBI have been the leading cause of morbidity and hospital admission in every major conflict since the Korean War. Pain remains a leading cause of presentation to military medical facilities, both in and out of theater. The absence of pain services is associated with a low return-to-duty rate among the deployed population. The most common pain complaints involve the low-back and neck, and studies have suggested that earlier treatment is associated with more significant improvement and a higher return to duty rate. It is recognized that military medicine is often at the forefront of medical innovation, and that many fields of medicine have reaped benefit from the conduct of war.

This study examines framed messages as a novel approach to promote self-management of chronic pain. Primary care patients reporting chronic pain (pain rated ≥ 4 on 0-10 NRS-I for ≥3 months) were randomly assigned to receive a gain- or loss-framed message promoting self-management of pain. Impact of the framed message on behavioural self-management (including communicating with providers, relaxation, activity pacing, pleasant activities and healthy lifestyle) was assessed. Post-message, individuals in the loss-frame condition reported significantly greater interest in and more knowledge gained from the information presented in the message (p≤0.03). Loss-frame participants were significantly more likely to express confidence that they would practice relaxation (p≤0.03). Pain readiness to change, pain self-efficacy and message frame independently influenced motivation to engage in relaxation as a self-management strategy. Across all behaviours assessed, there were no observed interactions between message frame and either pain self-efficacy or pain readiness to change (p>0.05). Framing may be useful to promote pain self-management; larger trials are needed to fully evaluate its potential and to further assess the applicability of framed communication to impact a broader range of chronic conditions.

Throughout the first years of the twenty-first century, neurotechnologies such as motor cortex stimulation (MCS), transcranial magnetic stimulation (TMS), and transcranial direct current stimulation (tDCS) have attracted scientific attention and been considered as potential tools to centrally modulate chronic pain, especially for those conditions more difficult to manage and refractory to all types of available pharmacological therapies. Interestingly, although the role of the motor cortex in pain has not been fully clarified, it is one of the cortical areas most commonly targeted by invasive and non-invasive neuromodulation technologies. Recent studies have provided significant advances concerning the establishment of the clinical effectiveness of primary MCS to treat different chronic pain syndromes. Concurrently, the neuromechanisms related to each method of primary motor cortex (M1) modulation have been unveiled. In this respect, the most consistent scientific evidence originates from MCS studies, which indicate the activation of top-down controls driven by M1 stimulation. This concept has also been applied to explain M1-TMS mechanisms. Nevertheless, activation of remote areas in the brain, including cortical and subcortical structures, has been reported with both invasive and non-invasive methods and the participation of major neurotransmitters (e.g., glutamate, GABA, and serotonin) as well as the release of endogenous opioids has been demonstrated. In this critical review, the putative mechanisms underlying the use of MCS to provide relief from chronic migraine and other types of chronic pain are discussed. Emphasis is placed on the most recent scientific evidence obtained from chronic pain research studies involving MCS and non-invasive neuromodulation methods (e.g., tDCS and TMS), which are analyzed comparatively.

Direct-to-consumer marketing has sparked ongoing debate concerning whether ads empower consumers to be agents of their own care or shift greater control to the pharmaceutical industry. Ads for over-the-counter (OTC) medications in particular portend to offer simple, harmless solutions for meeting the demands of social life. Rather than join the longstanding debate between consumer agency and social control in pharmaceutical advertising, I approach self-medication with over-the-counter (OTC) analgesics using Harm Reduction as a framework. From this perspective, consumption of OTC analgesics by chronic pain sufferers is a means of seeking some level of relief while also avoiding the stigma associated with prescription pain medication. Qualitative methods are used to analyze data from two sources: (1) semi-structured qualitative interviews with 95 participants in a trial examining the effectiveness of Traditional Chinese Medicine for Temporomandibular Disorders (TMD) from 2006 to 2011 in Tucson, AZ and Portland, OR; and (2) print, online, and television advertisements for three major brands of OTC pain medication. Participants described their use of OTC medications as minimal, responsible, and justified by the severity of their pain. OTC medication advertising, while ostensibly ambiguous and targeting all forms of pain, effectively lends support to the consumption of these medications as part of the self-projects of chronic pain sufferers, allowing them to reconcile conflicting demands for pain relief while being stoic and maintaining a positive moral identity. Describing OTC medication as "just over-the-counter" or "not real pain medication," sufferers engage in ideological harm reduction, distinguishing themselves from "those people who like taking pain medication" while still seeking relief. Justifying one's use of OTC medication as minimal and "normal," regardless of intake, avoids association with the addictive potential of prescription pain medications and

In the adult population chronic pain can lead to loss of productivity and earning potential, and decreased quality of life. There are distinct groups with increased vulnerability for the emergence of chronic pain. These groups may be defined by developmental status and/or life circumstances. Within the pediatric, geriatric, and drug abuser populations, chronic pain represents a significant health issue. This article focuses on known anatomic, physiologic, and genetic mechanisms underlying chronic pain in these populations, and highlights the need for a multimodal approach from multiple health care professionals for management of chronic pain in those with the most risk.

Many cortical areas play crucial roles in higher order brain functions such as pain and emotion-processing, decision-making, and cognition. Among them, anterior cingulate cortex (ACC) and insular cortex (IC) are two key areas. Glutamate mediates major excitatory transmission during long-term plasticity in both physiological and pathological conditions. Specifically related to nociceptive or pain behaviors, metabotropic glutamate subtype receptors (mGluRs) have been involved in different types of synaptic modulation and plasticity from periphery to the spinal cord. However, less is known about their functional roles in plasticity related to pain and its related behaviors within cortical regions. In this review, we first summarized previous studies of synaptic plasticity in both the ACC and IC, and discussed how mGluRs may be involved in both cortical long-term potentiation (LTP) and long-term depression (LTD)-especially in LTD. The activation of mGluRs contributes to the induction of LTD in both ACC and IC areas. The loss of LTD caused by peripheral amputation or nerve injury can be rescued by priming ACC or IC with activations of mGluR1 receptors. We also discussed the potential functional roles of mGluRs for pain-related behaviors. We propose that targeting mGluRs in the cortical areas including the ACC and IC may provide a new therapeutic strategy for the treatment of chronic pain, phantom pain or anxiety. PMID:27296638

[Purpose] To investigate whether pain, balance, and stabilization of the lumbar region can be improved through thoracic mobilization in addition to lumbar stabilizaing exercises. [Subjects and Methods] This study recruited 36 subjects with chronic low back pain lasting more than 12 weeks. The subjects recruited for this study participated voluntarily, and provided their signed consent to participation. [Results] Improvement in balance was largest in the lumbar stabilization exercise group, followed by the thoracic mobilization and exercise group, and the traditional physical therapy group, in decreasing order of effect. [Conclusion] In conclusion, lumbar stabilization exercises combined with thoracic mobilization had greater effects on stabilization of the lumbar region pain relief, and improvement of the function of the patients with chronic low back pain.

Twenty-two patients with multiple sclerosis (MS) and chronic pain we recruited into a quasi-experimental trial comparing the effects of self-hypnosis training (HYP) with progressive muscle relaxation (PMR) on pain intensity and pain interference; 8 received HYP and the remaining 14 participants were randomly assigned to receive either HYP or PMR. HYP-condition participants reported significantly greater pre- to postsession as well as pre- to posttreatment decreases in pain and pain interference than PMR-condition participants, and gains were maintained at 3-month follow-up. Most of the participants in both conditions reported that they continued to use the skills they learned in treatment and experienced pain relief when they did so. General hypnotizability was not significantly related to treatment outcome, but treatment-outcome expectancy assessed before and after the first session was. The results support the efficacy of self-hypnosis training for the management of chronic pain in persons with MS. PMID:19234967

Full Text Available Abstract Background Previous research has demonstrated that the significant others of individuals with persistent back pain may have important influences on work participation outcomes. The aim of this study was to extend previous research by including individuals who have remained in work despite persistent back pain in addition to those who had become incapacitated for work, along with their significant others. The purpose of this research was to explore whether the illness beliefs of significant others differed depending on their relative’s working status, and to make some preliminary identification of how significant others may facilitate or hinder work participation for those with persistent back pain. Methods Interviews structured around the Illness Perception Questionnaire (chronic pain version were conducted with back pain patients recruited from a hospital pain management clinic along with their significant others. Some patients had remained in work despite their back pain; others had ceased employment. Data were analysed using template analysis. Results There were clear differences between beliefs about, and reported responses to, back pain symptoms amongst the significant others of individuals who had remained in employment compared with the significant others of those who had ceased work. Three overarching themes emerged: perceived consequences of back pain, specific nature of employment and the impact of back pain on patient identity. Conclusions Significant others of employed individuals with back pain focused on the extent to which activity could still be undertaken despite back pain symptoms. Individuals out of work due to persistent back pain apparently self-limited their activity and were supported in their beliefs and behaviours by their significant others. To justify incapacity due to back pain, this group had seemingly become entrenched in a position whereby it was crucial that the individual with back pain was perceived
Full Text Available Neuropathic pain (NP is a chronic, debilitating symptomatology of lesions/injuries of the central and peripheral nervous system. As per pooled estimates, the prevalence is 7-8% in the general population; however, the prevalence varies with different neuropathic conditions. The aetiology can range from peripheral neuropathic conditions viz. peripheral diabetic neuropathic pain (PDNP, post-herpetic neuralgia (PHN, trigeminal neuralgia, HIV- associated polyneuropathy, cervical radiculopathy to central neuropathic conditions, viz. central post-stroke pain, spinal cord injury and the neuropathic pain associated with multiple sclerosis. Apart from the symptomatic perception of pain, neuropathic pain affects the cognitive and emotional aspects of the affected individual. The pain, being debilitating and resistant to over-the-counter analgesics, diminishes the quality of life, disrupts sleep and leads to psychiatric complications such as comorbid anxiety and depression. The management is palliative and involves drugs, psychological intervention, stimulations and nerve-blocking techniques. This review concentrates on the pharmacological therapeutic options available and focuses on the selection of the agent/s in accordance with the evidence. The first-line treatment includes the tricyclic antidepressants ([TCAs]; amitriptyline, nortriptyline, selective serotonin norepinephrine inhibitors ([SNRIs]; duloxetine, venlafaxine, calcium channel alpha 2 - delta ligands (pregabalin, gabapentin, carbamazepine and oxcarbazepine. Lidocaine plasters are first-line options for specific focal conditions such as post-herpetic neuralgia. The second-line therapy includes the opioid analgesics and tramadol. The choice of drug selection should complement the patient’s age, type of neuropathic condition, tolerability to an agent, comorbid condition and cost-effectiveness. Management must be individualized with a realistic and composite goal of making the pain tolerable and

The management of chronic pain continues to be a challenge, and despite taking prescribed medication for pain, patients continue to have pain of moderate severity. Current pain therapies are often inadequate, with side effects that limit medication adherence. There is a need to identify novel therapeutic targets for the management of chronic pain. One potential candidate for the treatment of chronic pain is therapies aimed at modulating the vasoactive peptide endothelin-1. In addition to vasoactive properties, endothelin-1 has been implicated in pain transmission in both humans and animal models of nociception. Endothelin-1 directly activates nociceptors and potentiates the effect of other algogens, including capsaicin, formalin, and arachidonic acid. In addition, endothelin-1 has been shown to be involved in inflammatory pain, cancer pain, neuropathic pain, diabetic neuropathy, and pain associated with sickle cell disease. Therefore, endothelin-1 may prove a novel therapeutic target for the relief of many types of chronic pain. Keywords: endothelin-1, acute pain, chronic pain, endothelin receptor antagonists

Full Text Available This pilot study assessed the effects of cardiopulmonary exercise testing and cardiorespiratory fitness on plasma neuropeptide Y (NPY, allopregnanolone and pregnanolone (ALLO, cortisol, and dehydroepiandrosterone (DHEA, and their association with pain sensitivity. Medication-free trauma-exposed participants were either healthy (n = 7 or experiencing comorbid chronic pain/posttraumatic stress disorder (PTSD (n = 5. Peak oxygen consumption (VO2 during exercise testing was used to characterize cardiorespiratory fitness. Peak VO2 correlated with baseline and peak NPY levels (r = 0.66, p < 0.05 and r = 0.69, p < 0.05, respectively, as well as exercise-induced changes in ALLO (r = 0.89, p < 0.001 and peak ALLO levels (r = 0.71, p < 0.01. NPY levels at the peak of exercise correlated with pain threshold 30 min after exercise (r = 0.65, p < 0.05, while exercise-induced increases in ALLO correlated with pain tolerance 30 min after exercise (r = 0.64, p < 0.05. In contrast, exercise-induced changes in cortisol and DHEA levels were inversely correlated with pain tolerance after exercise (r = –0.69, p < 0.05 and r = –0.58, p < 0.05, respectively. These data suggest that cardiorespiratory fitness is associated with higher plasma NPY levels and increased ALLO responses to exercise, which in turn relate to pain sensitivity. Future work will examine whether progressive exercise training increases cardiorespiratory fitness in association with increases in NPY and ALLO and reductions in pain sensitivity in chronic pain patients with PTSD.

Low Back Pain (LBP) is a major medical and socio-economical problem in the industrialized countries. Exercise therapy is the keystone of conservative treatment for chronic low back pain (CLBP). Numerous randomized trials and clinical practice guidelines have supported that exercise diminishes disability and pain severity while improving fitness and occupational status in patients with CLBP, as well as decrease its recurrence rate. However, there is no significant evidence that one particular type of exercise is clearly more effective than others. Here we present a descriptive review of different types of exercise for therapeutic or prevention purposes in patients with CLBP. Studies suggest that individually tailored, supervised exercise programs are associated with the best outcomes. High quality clinical trials are needed to determine the effectiveness of specific interventions (type, time, intensity and other characteristics) aimed at individuals and/or specific target groups.

BACKGROUND: Computer use may have an adverse effect on musculoskeletal outcomes. This study assessed the risk of neck and shoulder pain associated with objectively recorded professional computer use. METHODS: A computer programme was used to collect data on mouse and keyboard usage and weekly...... reports of neck and shoulder pain among 2146 technical assistants. Questionnaires were also completed at baseline and at 12 months. The three outcome measures were: (1) acute pain (measured as weekly pain); (2) prolonged pain (no or minor pain in the neck and shoulder region over four consecutive weeks...... followed by three consecutive weeks with a high pain score); and (3) chronic pain (reported pain or discomfort lasting more than 30 days and "quite a lot of trouble" during the past 12 months). RESULTS: Risk for acute neck pain and shoulder pain increased linearly by 4% and 10%, respectively, for each...

Chronic pain is multi-dimensional. At the physical level itself, beyond the nociceptive pathway, there is hyper arousal state of the components of the nervous system, which negatively influences tension component of the muscles, patterns of breathing, energy levels and mindset, all of which exacerbate the distress and affect the quality of life of the individual and family. Beginning with the physical body, Yoga eventually influences all aspects of the person: vital, mental, emotional, intell...

Rodent models of chronic pain may elucidate pathophysiological mechanisms and identify potential drug targets, but whether they predict clinical efficacy of novel compounds is controversial. Several potential analgesics have failed in clinical trials, in spite of strong animal modelling support for efficacy, but there are also examples of successful modelling.

Pain catastrophizing is becoming increasingly recognized as a clinically important psychological factor in chronic musculoskeletal pain. In this retrospective cross-sectional study, we have identified factors associated with an increased risk for pain catastrophizing in chronic neck pain (CNP) patients. We obtained data from our medical database on 331 patients who were treated for neck pain as their chief complaint at our clinic. The Pain Catastrophizing Scale (PCS) was used to define a high pain catastrophizing state (PCS score ≥21) in this study. Patient demographics, pain-related factors, and psychological factors were evaluated with logistic regression analysis to identify risk factors of high pain catastrophizing among patients with CNP. A total of 256 patients with CNP satisfied the study inclusion criteria and were included in the analyses. The median PCS score was 16 (range, 0-45), and 86 of 256 patients (33.5%) reported a PCS score ≥21. In multivariate analysis, high pain intensity, clinical insomnia, and a high level of depression/anxiety were strongly associated with high pain catastrophizing in patients with CNP. Depression was the strongest predictor of high pain catastrophizing, with an odds ratio of 7.35 (95% confidence interval 2.23-24.22). High pain catastrophizing was not significantly related to age, gender, comorbidities, or neck pain-related physical symptoms. In conclusion, poor psychological states should be addressed as an important part of pain management in CNP patients who are susceptible to high pain catastrophizing. PMID:27631217
Full Text Available Abstract Background On-going pain is one of the most debilitating symptoms associated with a variety of chronic pain disorders. An understanding of mechanisms underlying on-going pain, i.e. stimulus-independent pain has been hampered so far by a lack of behavioural parameters which enable studying it in experimental animals. Ultrasound vocalizations (USVs have been proposed to correlate with pain evoked by an acute activation of nociceptors. However, literature on the utility of USVs as an indicator of chronic pain is very controversial. A majority of these inconsistencies arise from parameters confounding behavioural experiments, which include novelty, fear and stress due to restrain, amongst others. Results We have developed an improved assay which overcomes these confounding factors and enables studying USVs in freely moving mice repetitively over several weeks. Using this improved assay, we report here that USVs increase significantly in mice with bone metastases-induced cancer pain or neuropathic pain for several weeks, in comparison to sham-treated mice. Importantly, analgesic drugs which are known to alleviate tumour pain or neuropathic pain in human patients significantly reduce USVs as well as mechanical allodynia in corresponding mouse models. Conclusions We show that studying USVs and mechanical allodynia in the same cohort of mice enables comparing the temporal progression of on-going pain (i.e. stimulus-independent pain and stimulus-evoked pain in these clinically highly-relevant forms of chronic pain.

Aberrant neuronal activity in injured peripheral nerves is believed to be an important factor in the development of neuropathic pain (NPP). Channel protein pCREB of that activity has been shown to mitigate the onset of associated molecular events in the nervous system, and sodium hydrosulfide (NaHS) could inhibit the expression of pCREB. However, whether NaHS could relieve the pain, it needs further experimental research. Furthermore, the clinical potential that NaHS was used to relieve pain was limited so it would be required. To address these issues, the rats of sciatic nerve chronic constriction injury (CCI) were given intraperitoneal injection of NaHS containing hydrogen sulfide (H2S). The experimental results showed that NaHS inhibited the reduction of paw withdrawal thermal latency (PWTL), mechanical withdrawal threshold (MWT), and the level of pCREB in CCI rats in a dose-dependent manner and they were greatly decreased in NaHSM group (P < 0.05). NaHS alleviates chronic neuropathic pain by inhibiting expression of pCREB in the spinal cord of Sprague-Dawley rats.

Methods A systematic review of articles in the international literature published between 2003 and 2014 was performed in the electronic databases PubMed, PsycINFO, LILACS, and SciELO using the terms (chronic pelvic pain AND (psychiatry OR psychiatric OR depression OR anxiety OR posttraumatic stress OR somatoform. The searches returned a total of 529 matches that were filtered according to predefined inclusion and exclusion criteria. A total of 18 articles were selected. Results The investigations focused mainly on the assessment of depression and anxiety disorders/symptoms, with rather high rates (17-38.6%. Depression and anxiety symptoms were more prevalent among women with CPP compared to healthy groups. Comparisons between groups with CPP and with specific pathologies that also have pain as a symptom showed that depression indicators are more frequent in CPP. Depressive symptoms tend to be more common in CPP and have no particular association with pain itself, the core feature of CPP. Discussion Other aspects of CPP seem to play a specific role in this association. Anxiety and other psychiatric disorders require further investigation so that their impact on CPP can be better understood.

Full Text Available Abstract Background Chronic back pain is a major public health problem and the primary reason patients seek acupuncture treatment. Therefore, an objective assessment of acupuncture efficacy is critical for making informed decisions about its appropriate role for patients with this common condition. This study addresses methodological shortcomings that have plagued previous studies evaluating acupuncture for chronic low back pain. Methods and Design A total of 640 participants (160 in each of four arms between the ages of 18 and 70 years of age who have low back pain lasting at least 3 months will be recruited from integrated health care delivery systems in Seattle and Oakland. They will be randomized to one of two forms of Traditional Chinese Medical (TCM acupuncture needling (individualized or standardized, a "control" group (simulated acupuncture, or to continued usual medical care. Ten treatments will be provided over 7 weeks. Study participants and the "Diagnostician" acupuncturists who evaluate participants and propose individualized treatments will be masked to the acupuncture treatment actually assigned each participant. The "Therapist" acupuncturists providing the treatments will not be masked but will have limited verbal interaction with participants. The primary outcomes, standard measures of dysfunction and bothersomeness of low back pain, will be assessed at baseline, and after 8, 26, and 52 weeks by telephone interviewers masked to treatment assignment. General health status, satisfaction with back care, days of back-related disability, and use and costs of healthcare services for back pain will also be measured. The primary analysis comparing outcomes by randomized treatment assignment will be analysis of covariance adjusted for baseline value. For both primary outcome measures, this trial will have 99% power to detect the presence of a minimal clinically significant difference among all four treatment groups and over 80% power for

The use of interventions based on the best available evidence in occupational therapy is essential, and evaluation of research is part of an evidence-based practice. The aim of this study was to assess the quality of studies describing and evaluating the effects of occupational therapy interventions on chronic pain. A systematic review of studies with diverse designs was carried out. A quality assessment was conducted, and the level of evidence was defined using the Research Pyramid Model. Of 19 included studies, three received the highest evidence level, and three were considered to be of high quality. The clinical recommendations that can be derived from this study are the following: occupational therapy interventions should start from the identified needs of the person with chronic pain; no support exists for the effectiveness of electromyographic biofeedback training as a supplement, more studies are needed to confirm this result; the efficacy of instructions on body mechanics was significant during work-hardening treatment; and occupational therapists need to perform and present more clinical studies of high quality and high-evidence level to build up a trustworthy arsenal of evidence-based interventions, for example, in persons with chronic pain.

Full Text Available Abstract Background Sleep disturbance is becoming increasingly recognised as a clinically important symptom in people with chronic low back pain (CLBP, low back pain >12 weeks, associated with physical inactivity and depression. Current research and international clinical guidelines recommend people with CLBP assume a physically active role in their recovery to prevent chronicity, but the high prevalence of sleep disturbance in this population may be unknowingly limiting their ability to participate in exercise-based rehabilitation programmes and contributing to poor outcomes. There is currently no knowledge concerning the effectiveness of physiotherapy on sleep disturbance in people with chronic low back pain and no evidence of the feasibility of conducting randomized controlled trials that comprehensively evaluate sleep as an outcome measure in this population. Methods/Design This study will evaluate the feasibility of a randomised controlled trial (RCT, exploring the effects of three forms of physiotherapy (supervised general exercise programme, individualized walking programme and usual physiotherapy, which will serve as the control group on sleep quality in people with chronic low back pain. A presenting sample of 60 consenting patients will be recruited in the physiotherapy department of Beaumont Hospital, Dublin, Ireland, and randomly allocated to one of the three groups in a concealed manner. The main outcomes will be sleep quality (self-report and objective measurement, and self-reported functional disability, pain, quality of life, fear avoidance, anxiety and depression, physical activity, and patient satisfaction. Outcome will be evaluated at baseline, 3 months and 6 months. Qualitative telephone interviews will be embedded in the research design to obtain feedback from a sample of participants' about their experiences of sleep monitoring, trial participation and interventions, and to inform the design of a fully powered future RCT

Overactivity (activity engagement that significantly exacerbates pain) is a common term in the chronic pain literature. Overactivity is accepted clinically as a behaviour that adversely affects an individual's daily functioning and is the target of one of the most widely endorsed pain management strategies among health professionals (ie, activity pacing). Little research, however, has investigated links between overactivity behaviour and indicators of patient functioning, and activity pacing has not been evaluated as a stand-alone treatment specifically for individuals with chronic pain who are habitually overactive. Two studies, using qualitative research designs and interpretative phenomenological analyses, were conducted to provide insight into (1) why certain individuals develop habitual overactivity patterns in response to pain, (2) the impact of overactivity on daily functioning, and (3) the value of activity pacing as a treatment strategy for this population. Findings suggest that overactivity behaviour is complex, influenced by multiple factors, and negatively impacts on multiple quality-of-life domains. Some participants who were followed up 3 to 6 months after a pain management program were able to learn pacing strategies and enact behaviour change with health professional support; however, the majority reported difficulties changing their behaviour after treatment. It is suggested that provision of pacing education, alone, to chronic pain patients who engage in overactivity behaviour may not be effective in eliciting behavioural change. Key factors that participants believed to contribute to the development and maintenance of their overactive behaviour in this study should be considered in future clinical approaches and empirical investigations.

AIM: To prove the hypothesis that patients with chronic pancreatitis would show increased theta activity during painful visceral stimulation.METHODS: Eight patients and 12 healthy controls underwent an experiment where the esophagus was electrically stimulated at the pain threshold using a nasal endoscope. The electroencephalogram (EEG) was recorded from 64 surface electrodes and "topographic matching pursuit" was used to extract the EEG information in the early brain activation after stimulation.RESULTS: A major difference between controls and patients were seen in delta and theta bands, whereas there were only minor differences in other frequency bands. In the theta band, the patients showed higher activity than controls persisting throughout the 450 ms of analysis with synchronous brain activation between the channels. The main theta components oscillated with 4.4Hz in the patients and 5.5Hz in the controls. The energy in the delta (0.5-3.5Hz) band was higher in the controls, whereas the patients only showed scattered activity in this band.CONCLUSION: The differences in the theta band indicate that neuropathic pain mechanisms are involved in chronic pancreatitis. This has important implications for the understanding and treatment of pain in these patients, which should be directed against drugs with effects on neuropathic pain disorders.

Background There is a paucity of studies investigating the clinical and biochemical characteristics of pain in chronic heart failure (CHF) patients.This study aimed to determine the clinical and biochemical characteristics and outcomes in Chinese patients with CHF and symptoms of pain.Methods Sociodemographics,serum levels of creatinine,NT-proBNP,high-sensitivity C-reactive protein (hs-CRP),tumor necrosis factor (TNF)-α,interleukin (IL)-6 and IL-10,and two-dimensional echocardiographic left ventricular ejection fraction (LVEF) were determined in 305 patients with CHF.A questionnaire packet including the Brief Pain Inventory (BPI) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to assess the degree of pain rated on a 0-10 scale and the quality of life (QOL).A six-minute walking test was performed during routine clinic visits.Major adverse cardiac events (MACE) were recorded; including all-cause or cardiac mortality and rehospitalization because of myocardial infarction,worsening heart failure or stroke at follow-up.Results Pain occurred in 25.6％ of CHF patients,and was more common when the New York Heart Association (NYHA) functional class was worse.More patients with pain were female in gender,and had more co-morbidities,lower LVEF,and shorter distance during the 6-minute walking test.Despite similar serum levels of creatinine,N-terminal prohormone of brain natriuretic peptide (NT-proBNP),IL-6 and IL-10,the TNF-α levels were higher and MLHFQ scores were greater in CHF patients with pain.At follow-up,CHF patients with moderate to severe pain (≥4 scale) had higher rates of all-cause and cardiac mortality and rehospitalization because of myocardial infarction,worsening heart failure or stroke.Multivariate regression analysis revealed that the presence of pain was an independent risk factor for MACE and reduced QOL in CHF patients.Conclusions Pain occurs in all stages of the CHF trajectory,and its incidence increases as clinical

Chronic pain is common in HIV, but incompletely characterized, including its underlying etiologies, its effect on healthcare utilization, and the characteristics of affected patients in the HIV primary care setting. These data are needed to design and justify appropriate clinic-based pain management services. Using a clinical data warehouse, we analyzed one year of data from 638 patients receiving standard-of-care antiretroviral therapy in a large primary care HIV clinic, located in the Harlem neighborhood of New York City. We found that 40% of patients carried one or more chronic pain diagnoses. The most common diagnoses were degenerative musculoskeletal disorders (eg, degenerative spinal disease and osteoarthritis), followed by neuropathic pain and headache disorders. Many patients (16%) had multiple chronic pain diagnoses. Women, older patients, and patients with greater burdens of medical illness, and psychiatric and substance use comorbidities were disproportionately represented among those with chronic pain diagnoses. Controlling for overall health status, HIV patients with chronic pain had greater healthcare utilization including emergency department visits and radiology procedures. In summary, our study demonstrates the high prevalence of chronic pain disorders in the primary care HIV clinic. Colocated interventions for chronic pain in this setting should not only focus on musculoskeletal pain but also account for complex multifaceted pain syndromes, and address the unique biopsychosocial features of this population. Furthermore, because chronic pain is prevalent in HIV and associated with increased healthcare utilization, developing clinic-based pain management programs could be cost-effective.
Dystrophy is a main factor of CRPS. A large number of patients do not develop dystrophy but, instead, they suffer from pain with limitation in movement, possible paraesthesia and/or swelling. This is then a chronic regional pain syndrome or (shoulder-arm-) hand-finger syndrome. These patients should never be confronted with the diagnosis Morbus Sudeck or algodystrophy, which are today also well known among non-professionals, to avoid pushing them into a status of constant severe invalidity. Histories, clinical examination, as well as a good personal understanding of the patient are indispensable. Knowing that pain, or the extent of pain, remains subjective until today, the clinical diagnosis depends on the absence of side differences in: a) the circumference of soft tissues of both upper extremities; b) the callosity of the palm; c) the bone-density. These three parameters allow verification of the consequences of the pain complaints (indirect pain verification). It is essential to find the cause for their suffering and to treat it as far as possible: 1) Too long and inappropriate immobilisation (patient's suffering not considered sufficiently). These patients can recover quickly when the right diagnosis is made in good time. 2) Limitation of movement due to scar, neuroma, or elongation pain: a) bizarre functional disabilities can develop; b) due to the patient's complaints, one or several operations would finally be performed, which will not lead to an improvement but rather to an aggravation of the pain; c) socially-induced purposeful pain increase, the typical statement of the patient will be: "I can't stand it any longer". Patients who are socially over-burdened, or have psycho-social problems, may experience a decline of performance or a post-traumatic stress disorder. Several patients will be introduced as illustrations for each of the relevant groups. PMID:20205065

Acceptance-based psychological interventions can potentially minimize the burden of chronic pain. This randomized controlled trial evaluated an internet-delivered, guided self-help intervention based on Acceptance and Commitment Therapy (ACT). A total of 238 chronic pain sufferers from the general population were randomly allocated to either ACT (n = 82), an internet-based control condition Expressive Writing (n = 79) or a waiting list condition (n = 77). Participants completed measures at baseline, posttreatment (3 months) and at a 3-month follow-up. At follow-up, ACT participants had improved in pain interference in daily life (primary outcome) compared to participants in Expressive Writing (Cohen's d = .47), but not compared to waiting list participants (p value = .11). Those who adhered to the ACT-intervention (48%) did improve significantly compared to waiting list participants (d = .49). ACT-participants also showed superior improvement on depression, pain intensity, psychological inflexibility and pain catastrophizing (d: .28-.60). Significant clinical improvement was present. Especially, 28% of ACT-participants showed general clinically relevant improvement in pain interference, as well as in pain intensity and depression (vs. Expressive Writing and waiting list 5%). Given these findings, internet-based ACT programs may be a promising treatment modality for chronic pain.
