    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.

    Barriers to clinical trial recruitment can delay study completion, potentially resulting in increased costs and an unrepresentative sample. In the current study of 150 participants with chronic pain, we used a computerized adaptive choice-based conjoint survey that included 8 characteristics that may affect enrollment in pharmacologic pain treatment trials (ie, treatment allocation, frequency of pain ratings, treatment administration method, current medications, number of study visits, availability of evening and weekend visits, invasiveness of laboratory procedures, payment). These data were analyzed using Sawtooth Software ver. 8.4.8 (Sawtooth Software, Inc, Orem, UT), which identifies the characteristics that dominate participants' decisions across multiple sets of potential trials. Three characteristics had the largest relative importance in participants' trial preferences: 1) invasiveness of required laboratory procedures (ie, 22%), with no procedures or blood tests preferred over ice-water sensory testing or skin biopsy; 2) ability to continue current pain medications (21%); and 3) payment for study participation (21%), with higher payment preferred. The fourth most important characteristic was number of study visits (13%), with participants preferring fewer in-person visits and more phone contacts. Understanding the preferences of potential participants is an important step toward enhancing enrollment in pain treatment trials.

Methods Semi-structured interviews were conducted with people with chronic knee pain, before (n = 29 and after (n = 23 participation on the programme. Thematic analysis was used to document people's baseline health beliefs, attitudes and cognitions, and to see if how and why these changed after completing the programme. Results Initially people had poor understanding and negative, fatalistic beliefs about the management or prognosis for knee pain. Following the programme the majority of participants had positive experiences describing improvement in pain, physical and psychosocial functioning, greater knowledge and understanding of their condition and treatment options, and in their ability to use exercise to control symptoms. Beliefs about the causation and prognosis of knee pain were unchanged, but their concerns about possible dangers of exercise had decreased, they appreciated how exercise could reduce symptoms (treatment beliefs and their confidence in their ability to use exercise to effect improvements (exercise self-efficacy increased. These improvements were attributed to the content and structure of the programme, and the care and guidance of the physiotherapist. Several expressed a need for on-going support. Conclusions ESCAPE-knee pain appears to achieve improvements by increasing people's treatment belief in safety and the utility of exercise to control symptoms, rather than alteration in their beliefs about causation or prognosis.

    Marfan syndrome (MFS) is a severe autosomal dominant connective tissue disorder that might influence peoples work ability. This cross sectional study aims to investigate work participation in adults with verified MFS diagnosis and to explore how the health related consequences of MFS and other factors might influence work participation. The prevalence of health problems in young adults compared to older adults with MFS was examined in association to work participation. A postal questionnaire including questions about work participation, demographic characteristics, MFS related health problems, chronic pain, and fatigue was sent to 117 adults with verified MFS (Ghent 1), and 62% answered. Fifty-nine percent were employed or students, significantly lower work participation than the General Norwegian Population (GNP), but higher than the Norwegian population of people with disability. Most young adults worked full-time despite extensive health problems, but the average age for leaving work was low. Few had received any work adaptations prior to retiring from work. In multiple logistic regression analysis, only age, lower educational level and severe fatigue were significantly associated with low work participation; not MFS related health problems or chronic pain. Fatigue appears to be the most challenging health problem to deal with in work, but the covariance is complex. Focus on vocational guidance early in life, more appropriate work adaptations, and psychosocial support might improve the possibility for sustaining in work for adults with MFS. More research about work challenges in adults with MFS is needed.

    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).

    In the last 2 decades, a growing body of research aimed at investigating the health benefits of Tai Chi in various chronic health conditions has been recognized in the literature. This article reviewed the history, the philosophy, and the evidence for the role of Tai Chi in a few selected chronic pain conditions. The ancient health art of Tai Chi contributes to chronic pain management in 3 major areas: adaptive exercise, mind-body interaction, and meditation. Trials examining the health benefit of Tai Chi in chronic pain conditions are mostly low quality. Only 5 pain conditions were reviewed: osteoarthritis, fibromyalgia, rheumatoid arthritis, low back pain, and headache. Of these, Tai Chi seems to be an effective intervention in osteoarthritis, low back pain, and fibromyalgia. The limitations of the Tai Chi study design and suggestions for the direction of future research are also discussed.

    The pharmacological treatment of chronic pain differs from acute pain management. In chronic non-cancer pain patients pharmacological treatment is only one element of an interdisciplinary approach. Not pain reduction only but gain in physical and social functioning is mandatory for continuation of therapy. The developpement of a strategy is the most important and difficult step toward an individual and sustained pharmacological pain treatment. Simple practical guidelines can help to find an individual therapeutic straight. Outcome parameters have to be determined. Check-ups for discontinuation of the therapy have to be done periodically. Exact documentation of effect and side effects prevents ungrateful and potential dangerous treatments. The WHO ladder remains the cornerstone of pharmacological pain treatment. Further analgesics as antidepressants and anticonvulsants are important in treatment of neuropathic or mixed pain states. Special considerations have to be done in opioid treatment of non-cancer pain regarding the lack of evidence in long term outcome and possible side effects and risks.

    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.

    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.

    Most patients with chronic pain receive multimodal treatment. There is scant literature to guide us, but when approaching combination pharmacotherapy, the practitioner and patient must weigh the benefits with the side effects; many medications have modest effect yet carry significant side effects that can be additive. Chronic pain often leads to depression, anxiety, and deconditioning, which are targets for treatment. Structured interdisciplinary programs are beneficial but costly. Interventions have their place in the treatment of chronic pain and should be a part of a multidisciplinary treatment plan. Further research is needed to validate many common combination treatments.

    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.

    2015-05-01

    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.

  7. Associations between Trunk Extension Endurance and Isolated Lumbar Extension Strength in Both Asymptomatic Participants and Those with Chronic Low Back Pain

    Directory of Open Access Journals (Sweden)

    Rebecca Conway

    2016-09-01

    Full Text Available Background: Strength and endurance tests are important for both clinical practice and research due to the key role they play in musculoskeletal function. In particular, deconditioning of the lumbar extensor musculature has been associated with low back pain (LBP. Due to the relationship between strength and absolute endurance, it is possible that trunk extension (TEX endurance tests could provide a proxy measure of isolated lumbar extension (ILEX strength and thus represent a simple, practical alternative to ILEX measurements. Though, the comparability of TEX endurance and ILEX strength is presently unclear and so the aim of the present study was to examine this relationship. Methods: Thirty eight healthy participants and nineteen participants with non-specific chronic LBP and no previous lumbar surgery participated in this cross-sectional study design. TEX endurance was measured using the Biering–Sorensen test. A maximal ILEX strength test was performed on the MedX lumbar-extension machine. Results: A Pearson’s correlation revealed no relationship between TEX endurance and ILEX strength in the combined group (r = 0.035, p = 0.793, the chronic LBP group (r = 0.120, p = 0.623 or the asymptomatic group (r = −0.060, p = 0.720. Conclusions: The results suggest that TEX is not a good indicator of ILEX and cannot be used to infer results regarding ILEX strength. However, a combination of TEX and ILEX interpreted together likely offers the greatest and most comprehensive information regarding lumbo-pelvic function during extension.

    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.

    Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes after treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical outcomes in a large database of chronic pain patients. In this observational cohort study, participants were 2272 patients treated in one of 3 university-affiliated multidisciplinary pain treatment centers. All patients received personalized care, including medical, psychological, and/or physical interventions. Patient expectations regarding pain relief and improvements in quality of life and functioning were measured before the first visit to the pain centers and served as predictor variables. Changes in pain intensity, depressive symptoms, pain interference, and tendency to catastrophize, as well as satisfaction with pain treatment and global impressions of change at 6-month follow-up, were considered as treatment outcomes. Structural equation modeling analyses showed significant positive relationships between expectations and most clinical outcomes, and this association was largely mediated by patients' global impressions of change. Similar patterns of relationships between variables were also observed in various subgroups of patients based on sex, age, pain duration, and pain classification. Such results emphasize the relevance of patient expectations as a determinant of outcomes in multimodal pain treatment programs. Furthermore, the results suggest that superior clinical outcomes are observed in individuals who expect high positive outcomes as a result of treatment.

    2016-10-01

    Despite marked differences in underlying pathophysiology, the current management of visceral pain largely follows the guidelines derived from the somatic pain literature. The effective management of patients with chronic visceral pain should be multifaceted, including both pharmacological and psychological interventions, thereby providing a mechanism-orientated approach to treatment. Patients can frequently become disenfranchised, and subsequently disengaged, with healthcare providers leading to repeated consultations. Thus, a key aspect of management is to break this cycle by validating patients' symptoms, adopting an empathic approach and taking time to educate patients. To optimize treatment and outcomes in chronic visceral pain we need to move away from approaches exclusively based on dealing with peripheral nociceptive input toward more holistic strategies, taking into account alterations in central pain processing.

    2014-01-01

    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 (HCs). 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 HCs 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 HCs 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. PMID:25136301

    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.

    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.

    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.

    Full Text Available The patients with chronic pain are increasingly reporting to the physicians for its management. Chronic pain are associated with head, neck and shoulder pain, spinal pain, pain in the joints and extremities, complex regional pain syndrome and phantom pain. The chronic pain is being managed worldwide. The different specialty of medicine is producing a lot of evidence through the published literature but the same is not being published in the field of chronic pain management. Though some evidence is being reported as to different aspects of pain management from different parts of the world but same is lacking from Indian subcontinent. This is in contrast to much done clinical work in this field as well. We present here the available evidence in relation to chronic pain management.

  4. Comprehensive management of chronic pain in haemophilia.

    Science.gov (United States)

    Young, G; Tachdjian, R; Baumann, K; Panopoulos, G

    2014-03-01

    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.

    2014-06-01

    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.

    Chronic pain is a debilitating condition and, in most cases, difficult to treat. A prominent example of this is neuropathic pain. Understanding pathophysiological mechanisms of pain and, therefore, making this knowledge into an effective treatment is still a challenge to experts. Pain can now be considered as a neuro-immune disorder, since recent data indicate critical involvement of innate and adaptive immune responses following injury, and this interaction plays an important role in the onset and perpetuation of chronic pain. The aim of this article is to review the relationship between immune system and chronic pain, especially about neuropathic pain, and focusing on cytokines, chemokines and lymphocytes.

    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.

  13. Chronic widespread pain in spondyloarthritis

    2014-06-01

    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.

  14. Mechanisms of chronic pain from whiplash injury.

    Science.gov (United States)

    Davis, Charles G

    2013-02-01

    This article is to provide insights into the mechanisms underlying chronic pain from whiplash injury. Studies show that injury produces plasticity changes of different neuronal structures that are responsible for amplification of nociception and exaggerated pain responses. There is consistent evidence for hypersensitivity of the central nervous system to sensory stimulation in chronic pain after whiplash injury. Tissue damage, detected or not by the available diagnostic methods, is probably the main determinant of central hypersensitivity. Different mechanisms underlie and co-exist in the chronic whiplash condition. Spinal cord hyperexcitability in patients with chronic pain after whiplash injury can cause exaggerated pain following low intensity nociceptive or innocuous peripheral stimulation. Spinal hypersensitivity may explain pain in the absence of detectable tissue damage. Whiplash is a heterogeneous condition with some individuals showing features suggestive of neuropathic pain. A predominantly neuropathic pain component is related to a higher pain/disability level.

    Background. Chronic postherniorrhaphy groin pain is defined as pain lasting >6 months after surgery, which is one of the most important complications occurring after inguinal hernia repair, which occurs with greater frequency than previously thought. Material and Methods. Patients undergoing elective inguinal hernioplasty in Victoria Hospital from November 2011 to May 2013 were included in the study. A total of 227 patients met the inclusion criteria and were available for followup at end of six months. Detailed preoperative, intraoperative, and postoperative details of cases were recorded according to proforma. The postoperative pain and pain at days two and seven and at end of six months were recorded on a VAS scale. Results. Chronic pain at six-month followup 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. Preemptive analgesia failed to show statistical significance in development of chronic pain (P = 0.079). Nerve injury was present in 22 of cases; it was found that nerve injury significantly affected development of chronic pain (P = 0.001). On multivariate analysis, it was found that development of chronic pain following hernia surgery was dependent upon factors like preoperative pain, type of anesthesia, nerve injury, postoperative local infiltration, postoperative complication, and most importantly the early postoperative pain. Conclusions. In the present study, we found that chronic pain following inguinal hernia repair causes significant morbidity to patients and should not be ignored. Preemptive analgesia and operation under local anesthesia significantly affect pain. Intraoperative identification and preservation of all inguinal nerves are very important. Early diagnosis and management of chronic pain can remove suffering of the patient.

    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.

  20. Mindfulness, acceptance and catastrophizing in chronic pain.

    Directory of Open Access Journals (Sweden)

    Maaike J de Boer

    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.

  1. Beyond Acute Pain: Understanding Chronic Pain in Infancy

    Miranda DiLorenzo

    2016-11-01

    Full Text Available This topical review presents the current challenges in defining chronic pain in infants, summarizes evidence from animal and human infant studies regarding the biological processes necessary for chronic pain signaling, and presents observational/experiential evidence from clinical experts. A literature search of four databases (CINAHL, EMBASE, PsycINFO, and MEDLINE was conducted, along with hand searches of reference lists. Evidence from animal studies suggest that important neurophysiological mechanisms, such as the availability of key neurotransmitters needed for maintenance of chronic pain, may be immature or absent in the developing neonate. In some cases, human infants may be significantly less likely to develop chronic pain. However, evidence also points to altered pain perception, such as allodynia and hyperalgesia, with significant injury. Moreover, clinicians and parents in pediatric intensive care settings describe groups of infants with altered behavioral responses to repeated or prolonged painful stimuli, yet agreement on a working definition of chronic pain in infancy remains elusive. While our understanding of infant chronic pain is still in the rudimentary stages, a promising avenue for the future assessment of chronic pain in infancy would be to develop a clinical tool that uses both neurophysiological approaches and clinical perceptions already presented in the literature.

    Methods for classifying chronic pain in population studies are highly variable, and prevalence estimates ranges from 11% to 64%. Limited knowledge about the persistence of pain and the validity of recall questions defining chronic pain make findings difficult to interpret and compare. The primary aim of the current study was to characterize the persistence of pain in the general population and to validate recall measures against longitudinal reporting of pain. A random sample of 6419 participants from a population study (the HUNT 3 study in Norway) was invited to report pain on the SF-8 verbal pain rating scale every 3 months over a 12-month period and to report pain lasting more than 6 months at 12-month follow-up. Complete data were obtained from 3364 participants. Pain reporting was highly stable (intraclass correlation 0.66, 95% confidence interval 0.65 to 0.67), and the prevalence of chronic pain varied considerably according to level of severity and persistence: 31% reported mild pain or more, whereas 2% reported severe pain on 4 of 4 consecutive measurements. When defined as moderate pain or more on at least 3 of 4 consecutive measurements, the prevalence was 26%. Compared with the longitudinal classification, a cross-sectional measure of moderate pain or more during the last week on the SF-8 scale presented a sensitivity of 82% and a specificity of 84%, and a sensitivity of 80% and a specificity of 90% when combined with a 6-month recall question. Thus pain reporting in the general population is stable and cross-sectional measures may give valid prevalence estimates of chronic pain.

    Intense abdominal pain is a prominent feature of chronic pancreatitis and its treatment remains a major clinical challenge. Basic studies of pancreatic nerves and experimental human pain research have provided evidence that pain processing is abnormal in these patients and in many cases resembles that seen in neuropathic and chronic pain disorders. An important ultimate outcome of such aberrant pain processing is that once the disease has advanced and the pathophysiological processes are firmly established, the generation of pain can become self-perpetuating and independent of the initial peripheral nociceptive drive. Consequently, the management of pain by traditional methods based on nociceptive deafferentation (e.g., surgery and visceral nerve blockade) becomes difficult and often ineffective. This novel and improved understanding of pain aetiology requires a paradigm shift in pain management of chronic pancreatitis. Modern mechanism based pain treatments taking into account altered pain processing are likely to increasingly replace invasive therapies targeting the nociceptive source, which should be reserved for special and carefully selected cases. In this review, we offer an overview of the current available pharmacological options for pain management in chronic pancreatitis. In addition, future options for pain management are discussed with special emphasis on personalized pain medicine and multidisciplinarity.

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

  7. Temperament traits and chronic pain: the association of harm avoidance and pain-related anxiety.

    Directory of Open Access Journals (Sweden)

    Peter Knaster

    Full Text Available OBJECTIVE: Anxiety symptoms are common in chronic pain patients. High levels of anxiety are associated with increased pain experience and disability. Proneness to anxiety has a large interindividual variation. The aim of the study was to determine whether the anxiety-related temperament trait Harm Avoidance (HA, is associated with pain-related anxiety. METHODS: One hundred chronic pain patients in a multidisciplinary pain clinic participated in the study. The patients were assessed using the HA scale of the Temperament and Character Inventory (TCI of Cloninger and Pain Anxiety Symptoms Scale-20 (PASS-20. Both the HA total score and the four subscales of HA were analyzed. Current pain intensity was measured using the Visual Analogue Scale (VAS. The Beck Depression Inventory (BDI was used to control for the influence of depression on the personality measurement. RESULTS: The HA total score was associated with PASS-20, but the association became non-significant after controlling for depression. The HA4 Fatigability subscale was associated with the PASS scales. Depression did not influence this association. Pain intensity was not correlated with HA or the PASS scales. However, the association between HA4 Fatigability and PASS was influenced by pain intensity. Higher pain intensity was associated with stronger association between the scales. CONCLUSION: Harm Avoidance, representing temperament and trait-related anxiety, has relevance in pain-related anxiety. Assessing personality and temperament may deepen the clinician's understanding of the pain experience and behavior in chronic pain patients.

    In the United States, millions of Americans are affected by chronic pain, which adds heavily to national rates of morbidity, mortality, and disability, with an ever-increasing prevalence. According to a 2011 report titled Relieving Pain in America: A Blueprint for Transforming Prevention, Care, Education, and Research by the Institute of Medicine of the National Academies, pain not only exacts its toll on people's lives but also on the economy with an estimated annual economic cost of at least $560 - 635 billion in health care costs and the cost of lost productivity attributed to chronic pain. Intravenous infusions of certain pharmacologic agents have been known to provide substantial pain relief in patients with various chronic painful conditions. Some of these infusions are better, and although not necessarily the first therapeutic choice, have been widely used and extensively studied. The others show promise, however are in need of further investigations. This article will focus on non-opiate intravenous infusions that have been utilized for chronic painful disorders such as fibromyalgia, neuropathic pain, phantom limb pain, post-herpetic neuralgia, complex regional pain syndromes (CRPS), diabetic neuropathy, and central pain related to stroke or spinal cord injuries. The management of patients with chronic pain conditions is challenging and continues to evolve as new treatment modalities are explored and tested. The following intravenous infusions used to treat the aforementioned chronic pain conditions will be reviewed: lidocaine, ketamine, phentolamine, dexmedetomidine, and bisphosphonates. This overview is intended to familiarize the practitioner with the variety of infusions for patients with chronic pain. It will not, however, be able to provide guidelines for their use due to the lack of sufficient evidence.

  10. Assessment of patients with chronic pain.

    2013-07-01

    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.

  11. Nonspecificity of Chronic Soft Tissue Pain Syndromes

    Directory of Open Access Journals (Sweden)

    Eldon Tunks

    1997-01-01

    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.

    This study examined sleep patterns in female adolescents with chronic musculoskeletal pain. Twenty-six participants with chronic musculoskeletal pain completed questionnaires during their clinic visit, and three 24-Hour Sleep Patterns Interviews during the following 2 weeks. Compared to normative data (Acebo & Carskadon, 2002), adolescents with chronic pain reported similar total sleep time (TST) and bedtimes. However, study participants reported significantly longer sleep onset latency, more night wakings, a later morning wake time, and more symptoms of daytime sleepiness. Pain improved after sleep for 27% of the study sample, and was associated with longer TST. Finally, depression and anxiety were related to daytime sleepiness, but not total sleep time or sleep onset latency. Female adolescents with chronic pain either may be more sensitive to the chronic sleep debt that is common in this age group, or they may experience underlying physiological sleep disrupters (e.g., periodic limb movement disorder) or sleep abnormalities (e.g., alpha-delta intrusions) not measured in this study. Additional research is needed to examine the complex relation between sleep and chronic musculoskeletal pain.

    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.

    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.

    Several empirical studies have shown that personal characteristics act as differential variables, which determine how pain is experienced and how the chronic pain patient adjusts to pain. The main aim of the present research is to review the relationships between some dispositional characteristics and pain adjustment. Taking into account the empirical literature, 6 personality traits that are relevant to the pain experience have been selected: neuroticism, anxiety sensitivity, and experiential avoidance as risk factors that increase the probability of patients experiencing a disability; and extraversion, optimism, and resilience as personal resources that increase their capacity to manage pain effectively. The results suggest that it would be useful to include an assessment of normal personality structure during the multi-dimensional evaluation of a person with chronic pain. Understanding these individual personality characteristics will aid in designing pain intervention programs and help predict possible treatment outcomes.

    Full Text Available Samantha R Fashler, Joel Katz Department of Psychology, York University, Toronto, ON, CanadaAbstract: The present study used eye-tracking technology to assess whether individuals who report chronic pain direct more attention to sensory pain-related words than do pain-free individuals. A total of 113 participants (51 with chronic pain, 62 pain-free were recruited. Participants completed a dot-probe task, viewing neutral and sensory pain-related words while their reaction time and eye movements were recorded. Eye-tracking data were analyzed by mixed-design analysis of variance with group (chronic pain versus pain-free as the between-subjects factor, and word type (sensory pain versus neutral as the within-subjects factor. Results showed a significant main effect for word type: all participants attended to pain-related words more than neutral words on several eye-tracking parameters. The group main effect was significant for number of fixations, which was greater in the chronic pain group. Finally, the group by word type interaction effect was significant for average visit duration, number of fixations, and total late-phase duration, all greater for sensory pain versus neutral words in the chronic pain group. As well, participants with chronic pain fixated significantly more frequently on pain words than did pain-free participants. In contrast, none of the effects for reaction time were significant. The results support the hypothesis that individuals with chronic pain display specific attentional biases toward pain-related stimuli and demonstrate the value of eye-tracking technology in measuring differences in visual attention variables.Keywords: attention, chronic pain, dot-probe task, eye-tracking

    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.

    Neck pain is considered to be one of the most common chronic pain conditions in modern society. Various structures identified as capable of transmitting pain in the cervical spine include facet joints, intervertebral discs, nerve root dura, ligaments, fascia, and muscles. The prevalence of cervical facet joint pain in patients with chronic pain after whiplash has been determined as 54% to 60%. However, the prevalence of chronic cervical facet joint pain has not yet been determined in a heterogenous population or in patients with cervical spine pain of idiopathic origin in a controlled environment. This study evaluated 160 patients seen in one interventional pain management practice in a non-university setting. Cervical facet joints were investigated with diagnostic blocks using lidocaine 1% preservative free initially, followed by bupivacaine 0.25%, usually 2 to 4 weeks apart. The study population consisted of 76 women and 30 men aged 43 +/- 13 years of age (mean +/- SD). Mode of onset of neck pain was determined as following a traumatic incident in 48% of the patients, whereas it was with gradual onset without an identifiable specific incident in the remaining 55 patients (52%). Eighty-one or 70% of the patients (70%) reported a definite response to lidocaine blocks. Confirmatory blocks with bupivacaine were performed in 81 patients with 64 patients with 60% of the total sample, or 79%, of the lidocaine-positive group reporting definite response with improvement in their pain. Thus, a prevalence rate of facet joint pain in chronic neck pain was determined to be 60% (95% CI, 50%-70%), with a false positive rate of controlled diagnostic blocks of 40% (95% CI, 34%-46%).

    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. Repeated measures analysis showed significant changes (P pain patients was significantly high, with female gender being a significant risk factor. With proper diagnosis and expert management, MPS has a favourable outcome. PMID:21716607

    Purpose Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent urologic disorder among men, but its etiology is still poorly understood. Our objective was to examine the relationship between physical activity and incidence of CP/CPPS in a large cohort of male health professionals. Methods We conducted a prospective cohort study among men in the Health Professionals Follow-up Study followed from 1986 to 2008. The study population included 20,918 men who completed all CP/CPPS questions on the 2008 questionnaire. Leisure-time physical activity, including type and intensity of activity, was measured by questionnaire in 1986. A National Institute of Health Chronic Prostatitis Symptom Index pain score was calculated based on the responses on the 2008 questionnaire. Participants with pain scores ≥ 8 were considered CP/CPPS cases (n=689). Results Higher leisure-time physical activity was associated with lower risk of CP/CPPS. The multivariable-adjusted odds ratio (OR) comparing >35.0 to ≤3.5 MET-h/wk of physical activity was 0.72 (95% confidence interval (CI): 0.56, 0.92, p for trend <0.001). Observed inverse associations between physical activity and CP/CPPS were similar for both moderate- and vigorous-intensity activities. Sedentary behavior, measured as time spent watching television, was not associated with risk of CP/CPPS (p for trend 0.64). Conclusions Findings from this study, the first large scale and most comprehensive study to date on this association, suggest that higher levels of leisure-time physical activity may lower risk of CP/CPPS in middle-aged and older men.

    Children and adolescents frequently experience chronic pain that can disrupt their usual activities and lead to poor physical and emotional functioning. The fear avoidance model of pain with an emphasis on the maladaptive behaviors that lead to activity avoidance has guided research and clinical practice. However, this model does not take into consideration variability in responses to pain, in particular the active pursuit of goals despite pain. This review aims to introduce a novel conceptualization of children’s activity engagement versus avoidance using the framework of goal pursuit. We propose a new model of Goal Pursuit in Pediatric Chronic Pain, which proposes that the child’s experience of pain is modified by child factors (e.g., goal salience, motivation/energy, pain-related anxiety/fear, and self-efficacy) and parent factors (e.g., parent expectations for pain, protectiveness behaviors, and parent anxiety), which lead to specific goal pursuit behaviors. Goal pursuit is framed as engagement or avoidance of valued goals when in pain. Next, we recommend that research in youth with chronic pain should be reframed to account for the pursuit of valued goals within the context of pain and suggest directions for future research.

    Patients presenting for treatment of chronic pain often believe that pain reduction must be achieved before returning to normal functioning. However, treatment programs for chronic pain typically take a rehabilitative approach, emphasizing decreasing pain-related disability first with the expectation that pain reduction will follow. This information is routinely provided to patients, yet no studies have systematically examined the actual trajectories of pain and disability in a clinical care setting. In this study of youth with chronic pain (N=94, 8 to 18 years), it was hypothesized that 1) functional disability and pain would decrease over the course of psychological treatment for chronic pain and 2) functional disability would decrease more quickly than pain intensity. Participants received cognitive behavioral therapy (CBT) for pain management (M=5.6 sessions) plus standard medical care. The Functional Disability Inventory and a Numeric Rating Scale of average pain intensity were completed by the child at every CBT session. Hierarchical linear modeling was conducted to examine the longitudinal trajectories of disability and pain. Standardized estimates of the slopes of change were obtained to test differences in rates of change between pain and disability. Results showed an overall significant decline in functional disability over time. Although pain scores reduced slightly from pretreatment to posttreatment, the longitudinal decline over treatment was not statistically significant. As expected, the rate of change of disability was significantly more rapid than pain. Evidence for variability in treatment response was noted, suggesting the need for additional research into individual trajectories of change in pediatric pain treatment.

    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.

    2014-07-01

    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.

    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.

    2014-01-01

    The literature on methods of invasive local treatment of chronic pain was analyzed. We reviewed 14 publications including meta-analyses and systematic reviews. The use of regional anesthesia conducted by anesthesiologists in pain clinics demonstrated the evidence based efficacy of different types of peridural injections of local anesthetics with steroids in patients with root pain syndromes at cervical and lumbar levels. Therapeutic blockades of the occipital nerve is effective method of treatment of cervicogenic and cluster headache as well as occipital nerve neuralgia. There are clear indications of the efficacy of local injections in primary chronic cephalgia (migraine and headache of tension). The possibility of the abortion of the pain information flow in peripheral nociceptive pathways and, as a consequence, breaking the vicious circle is emphasized. Issues on the efficacy of local injections at trigger points in the treatment of chronic pain are highlighted.

    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.

    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.

  2. Personality factors and disorders in chronic pain.

    It has long been recognized that there is a relationship between certain personality types and personality disorders (PD) and chronic nonmalignant pain (CP). The relationship, however, is far from understood and the physiological and psychological mechanisms that underlie it are unclear. Those who treat chronic pain face many challenges when dealing with individuals who have personality disorders and they often become frustrated when interacting with these patients. Patients with certain traits and personality disorders may continue to worry and ruminate about their symptoms long after the tissue pathology has resolved. Other individuals may overly rely on the clinician and assume a passive role in their treatment, thereby decreasing the likelihood for a positive outcome. Moreover, patients with personality disorders may be demanding (eg, borderline), self-absorbed (eg, narcissistic), or substance seeking (eg, antisocial, borderline). In an attempt to improve management of such patients, pain specialists have attempted to better understand the complex relationship between personality and chronic pain. In this article, we will review the predominant historical and current theories of pain and personality, discuss aspects of the gate-control theory of pain that may relate to personality, and discuss the diathesis-stress model of personality disorders in pain. Last, we will review studies of personality and personality disorders in chronic pain and their treatment implications. We conclude that, based on the underlying neurochemistry, there may be a direct or indirect link between PD and CP, but further prospective research, both on the biological and psychological relationship, should be conducted.

    Objectives In the context of widespread opioid use, increased emphasis has been placed on the potentially deleterious effects of concurrent benzodiazepine (BZD) and opioid use. Although use of opioids in chronic pain has been a major focus, BZD use is equally concerning. Thus, the primary aim of this study was to determine the associations between BZD and opioid use in adults with chronic pain upon admission to an outpatient interdisciplinary pain rehabilitation (IPR) program. Methods The study cohort involved 847 consecutive patients admitted to a 3-week outpatient IPR program from January 2013 through December 2014. Study variables included baseline demographic and clinical characteristics, Center for Epidemiologic Studies-Depression Scale, Pain Catastrophizing Scale, and the pain severity subscale of the Multidimensional Pain Inventory. Results Upon admission, 248 (29%) patients were taking BZDs. Patients using BZDs were significantly more likely to use opioids and to be female. Additionally, patients using BZDs had significantly greater depression, pain catastrophizing, and pain severity scores. In univariable logistic regression analysis, opioid use, female sex, and greater scores of depression, pain catastrophizing, and pain severity were significantly associated with BZD use. In multivariable logistic regression analysis adjusted for age, sex, pain duration, opioid use, depression, pain catastrophizing, and pain severity, only female sex and greater depression scores were significantly associated with BZD use. Discussion Among patients participating in an outpatient IPR program, female sex and greater depression scores were associated with BZD use. Results identify a high prevalence of BZD use in patients with chronic pain and reinforce the need to weigh the risks versus benefits when prescribing in this patient population. PMID:28223841

    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.

    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.

    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. PMID:25741834

    The intensity of acute and chronic pain depends on interactions between peripheral impulse input and CNS pain mechanisms, including facilitation and inhibition. Whereas tonic pain inhibition is a characteristic of most pain-free individuals, pain facilitation can be detected in many chronic pain patients. The capability to inhibit pain is normally distributed along a wide continuum in the general population and can be used to predict chronic pain. Accumulating evidence suggests that endogenou...

    Spatial perception is sensitive to the energetic costs required to perform intended actions. For example, hills look steeper to people who are fatigued or burdened by a heavy load. Similarly, perceived distance is also influenced by the energy required to walk or throw to a target. Such experiments demonstrate that perception is a function, not just of optical information, but also of the perceiver’s potential to act and the energetic costs associated with the intended action. In the current paper, we expand on the notion of “cost” by examining perceived distance in patients diagnosed with chronic pain, a multifactorial disease, which is experienced while walking. We found that chronic pain patients perceive target distances to be farther away than a control group. These results indicate the physical, and perhaps emotional, costs of chronic pain affect spatial perceptions. PMID:18949471

  11. Anxiety and Related Factors in Chronic Pain

    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.

    2016-08-25

    The Mexican artist Frida Kahlo (1907-1954) is one of the most celebrated artists of the 20th century. Although famous for her colorful self-portraits and associations with celebrities Diego Rivera and Leon Trotsky, less known is the fact that she had lifelong chronic pain. Frida Kahlo developed poliomyelitis at age 6 years, was in a horrific trolley car accident in her teens, and would eventually endure numerous failed spinal surgeries and, ultimately, limb amputation. She endured several physical, emotional, and psychological traumas in her lifetime, yet through her art, she was able to transcend a life of pain and disability. Of her work, her self-portraits are conspicuous in their capacity to convey her life experience, much of which was imbued with chronic pain. Signs and symptoms of chronic neuropathic pain and central sensitization of nociceptive pathways are evident when analyzing her paintings and medical history. This article uses a narrative approach to describe how events in the life of this artist contributed to her chronic pain. The purpose of this article is to discuss Frida Kahlo's medical history and her art from a modern pain sciences perspective, and perhaps to increase our understanding of the pain experience from the patient's perspective.

    Purpose Although chronic prostatitis/chronic pelvic pain syndrome is a prevalent urological disorder among men of all ages, its etiology remains unknown. Only a few previous studies have examined associations between lifestyle factors and chronic prostatitis/chronic pelvic pain syndrome, of which most were limited by the cross-sectional study design and lack of control for possible confounders. To address these limitations we performed a cohort study of major lifestyle factors (obesity, smoking and hypertension) and chronic prostatitis/chronic pelvic pain syndrome risk in the HPFS (Health Professionals Follow-up Study), a large ongoing cohort of United States based male health professionals. Materials and Methods The HPFS includes 51,529 men who were 40 to 75 years old at baseline in 1986. At enrollment and every 2 years thereafter participants have completed questionnaires on lifestyle and health conditions. In 2008 participants completed an additional set of questions on recent chronic prostatitis/chronic pelvic pain syndrome pain symptoms modified from the NIH (National Institutes of Health)-CPSI (Chronic Prostatitis Symptom Index) as well as questions on approximate date of symptom onset. The 653 participants with NIH-CPSI pain scores 8 or greater who first experienced symptoms after 1986 were considered incident chronic prostatitis/chronic pelvic pain syndrome cases and the 19,138 who completed chronic prostatitis/chronic pelvic pain syndrome questions but did not report chronic prostatitis/chronic pelvic pain syndrome related pain were considered noncases. Results No associations were observed for baseline body mass index, waist circumference, waist-to-hip ratio, cigarette smoking and hypertension with chronic prostatitis/chronic pelvic pain syndrome risk (each OR ≤1.34). Conclusions In this large cohort study none of the lifestyle factors examined was associated with chronic prostatitis/chronic pelvic pain syndrome risk. As the etiology of chronic

    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.

    People with chronic pain and comorbid posttraumatic stress disorder (PTSD) report more severe pain and poorer quality of life than those with chronic pain alone. This study evaluated the extent to which associations between PTSD and chronic pain interference and severity are mediated by pain-related coping strategies and depressive symptoms. Veterans with chronic pain were divided into 2 groups, those with (n=65) and those without (n=136) concurrent PTSD. All participants completed measures of pain severity, interference, emotional functioning, and coping strategies. Those with current PTSD reported significantly greater pain severity and pain interference, had more symptoms of depression, and were more likely to meet diagnostic criteria for a current alcohol or substance use disorder (all p-values self-statements. Illness-focused pain coping (i.e., guarding, resting, and asking for assistance) and depressive symptoms jointly mediated the relationship between PTSD and both pain interference (total indirect effect=0.194, p<.001) and pain severity (total indirect effect=0.153, p=.004). Illness-focused pain coping also evidenced specific mediating effects, independent of depression. In summary, specific pain coping strategies and depressive symptoms partially mediated the relationship between PTSD and both pain interference and severity. Future research should examine whether changes in types of coping strategies after targeted treatments predict improvements in pain-related function for chronic pain patients with concurrent PTSD.

    2013-08-01

    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.

  5. Opioid Therapy for Chronic Nonmalignant Pain

    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.

  6. Mechanism for chronic pain generation

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    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.

    Mental defeat is a psychological construct that has recently been applied to characterize the experience of chronic pain. Elevated levels of mental defeat have been identified in patients with chronic pain, and while its presence distinguishes treatment seeking from non-treatment seeking individuals, the link between mental defeat and disability in chronic pain is yet to be established. The current study investigated the extent to which mental defeat is associated with pain-related interference, distress and disability. A total of 133 participants completed the Pain Self Perception Scale that assessed mental defeat in relation to pain. Moreover, the participants were asked to complete a set of questionnaires that measured pain interference, distress, disability and other demographic (age, body mass index), clinical (pain intensity) and psychological (catastrophizing, worry, rumination and health anxiety) predictors of disability. Mental defeat was found to be strongly correlated with pain interference, sleep disturbance, anxiety, depression, functional disability and psychosocial disability. These correlations remained significant even when pain intensity and demographic variables were partialled out. Relative to chronic pain patients with lower levels of mental defeat, those with higher levels of mental defeat reported greater degree of pain interference, distress and disability. In a series of regression analyses, mental defeat emerged as the strongest predictor of pain interference, depression and psychosocial disability, whereas catastrophizing was the best predictor of sleep interference, anxiety and functional disability. These findings suggest that mental defeat may be an important mediator of distress and disability in chronic pain. Theoretical and clinical implications are discussed.

    Full Text Available 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.

    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.

    Acupuncture is widely used by patients with neck pain, but there is a lack of information about its effectiveness in routine medical care. The aim was to investigate the effectiveness of acupuncture in addition to routine care in patients with chronic neck pain compared to treatment with routine care alone. We performed a randomized controlled multicentre trial plus non-randomized cohort in general practices in Germany. 14,161 patients with chronic neck pain (duration >6 months). Patients were randomly allocated to an acupuncture group or a control group receiving no acupuncture. Patients in the acupuncture group received up to 15 acupuncture sessions over three months. Patients who did not consent to randomization received acupuncture treatment. All subjects were allowed to receive usual medical care in addition to study treatment. Neck pain and disability (NPAD Scale by Wheeler) after three months. Of 14,161 patients (mean age 50.9+/-13.1 years, 68% female) 1880 were randomized to acupuncture and 1886 to control, and 10,395 included into the non-randomized acupuncture group. At three months, neck pain and disability improved by 16.2 (SE: 0.4) to 38.3 (SE: 0.4); and by 3.9 (SE: 0.4) to 50.5 (SE: 0.4), difference 12.3 (pacupuncture and control group, respectively. Treatment success was essentially maintained through six months. Non-randomized patients had more severe symptoms at baseline and showed higher neck pain and disability improvement compared to randomized patients. Treatment with acupuncture added to routine care in patients with chronic neck pain was associated with improvements in neck pain and disability compared to treatment with routine care alone.

    2005-12-01

    Chronic nonspecific neck pain is a common problem in rheumatology and may resist conventional treatment. Pathophysiological links exist between the cervical spine and masticatory system. Occlusal disorders may cause neck pain and may respond to dental treatment. The estimated prevalence of occlusal disorders is about 45%, with half the cases being due to functional factors. Minor repeated masticatory dysfunction (MD) with craniocervical asymmetry is the most common clinical picture. The pain is usually located in the suboccipital region and refractory to conventional treatment. The time pattern may be suggestive, with nocturnal arousals or triggering by temporomandibular movements. MD should be strongly suspected in patients with at least two of the following: history of treated or untreated MD, unilateral temporomandibular joint pain and clicking, lateral deviation during mouth opening, and limitation of mouth opening (less than three fingerbreadths). Rheumatologists should consider MD among causes of neck pain, most notably in patients with abnormal craniocervical posture, signs linking the neck pain to mastication, and clinical manifestations of MD. Evidence suggesting that MD may cause neck pain has been published. However, studies are needed to determine whether treatment of MD can relieve neck pain.

    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

    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.

    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 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.

    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.

    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.

    Full Text Available Abstract Background Persistent whiplash associated disorders (WAD have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM, conjunct motion, joint position error and ROM-variability. Methods Participants (n = 173 were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal, and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Results Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9° (95% CI; 12.2–15.6 for the WAD group, 17.9° (95% CI; 16.1–19.6 for the chronic neck pain group and 25.9° (95% CI; 23.7–28.1 for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Conclusion Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a

    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.

    Somatic focus refers to the tendency to notice and report physical symptoms, and has been investigated in relation to chronically painful conditions. This study investigated the relationship between somatic focus, as measured by the Pennebaker Inventory of Limbic Languidness (PILL), negative affect and pain. A secondary purpose of the present study was to examine sex differences in these relationships. Participants included 280 chronic pain patients (69.6% females, 88.9% Caucasian), who completed a battery of self-report measures on somatic focus, pain, negative affect, coping, and dysfunction. Results for the overall sample revealed that the PILL shares considerable variance with measures of negative affect, particularly with the physiological components of anxiety and depression. When the results were analyzed separately for male and female patients, it was found that several components of negative affect and cognitive factors play a stronger role in predicting somatic focus among men compared to women. Additional analyses then examined whether somatic focus was predictive of male and female patients' pain reports. Results indicated that somatic focus explained a small, but unique amount of variance in female patients' pain reports, which differed from the relationship observed among male patients.

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.

    The purpose of this study was to examine the base rate of cognitive and neurobehavioural complaints in patients with chronic pain (N = 170) who had not sustained a head injury. The patients completed a packet of questionnaires that contained numerous questions regarding physical, cognitive, and psychological symptoms. The 'postconcussive-like' symptoms were selected and analysed. Specific symptom endorsement rates ranged from 5% to 76.5%. Disturbed sleep, fatigue, and irritability were reported by the majority of chronic pain patients. Cognitive complaints relating to forgetfulness (29%), difficulty maintaining attention (18%), and difficulty with concentration or thinking (16.5%) were endorsed by a significant minority of patients. Most patients (80.6%) endorsed three or more symptoms from Category C of the DSM-IV Postconcussional Disorder research criteria. This study further illustrates that postconcussive-like symptoms are not unique sequelae of mild head injury, and the presence of chronic pain should be considered when interpreting patients' physical, cognitive, and psychological complaints following closed head injury.

    Pain in sickle cell disease (SCD) is associated with increased morbidity, mortality, and high health care costs. Although episodic acute pain is the hallmark of this disorder, there is an increasing awareness that chronic pain is part of the pain experience of many older adolescents and adults. A common set of criteria for classifying chronic pain associated with SCD would enhance SCD pain research efforts in epidemiology, pain mechanisms, and clinical trials of pain management interventions, and ultimately improve clinical assessment and management. As part of the collaborative effort between the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks public-private partnership with the U.S. Food and Drug Administration and the American Pain Society, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy initiative developed the outline of an optimal diagnostic system for chronic pain conditions. Subsequently, a working group of experts in SCD pain was convened to generate core diagnostic criteria for chronic pain associated with SCD. The working group synthesized available literature to provide evidence for the dimensions of this disease-specific pain taxonomy. A single pain condition labeled chronic SCD pain was derived with 3 modifiers reflecting different clinical features. Future systematic research is needed to evaluate the feasibility, validity, and reliability of these criteria.

    Educating the general public about chronic pain and its care is a national health priority. We evaluated knowledge, attitudes, and beliefs (KAB) of a 5-state, population-based sample of Hispanic individuals aged 35 to 75 years without chronic pain, representing more than 8.8 million persons. A Web-based survey assessed KAB using an adapted version of the Survey of Pain Attitudes-Brief and self-reported knowledge about chronic pain (nothing, a little, a lot). In unweighted analyses of participants (N = 349), the mean age was 52.0 (±10.6) years, 54% were women, 53% preferred Spanish, and 39% did not graduate from high school. More participants reported knowing nothing about chronic pain (24%) than a lot (12%). In weighted logistic models with knowing nothing as the reference, knowing a lot was associated with greater KAB for chronic pain-related emotions, functioning, and cure (all P chronic pain care, these data underscore the need for effective public educational campaigns about chronic pain.

    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 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.

    The multisystem nature of female chronic pelvic pain (CPP) makes this condition a challenge for physical therapists and other health care providers to manage. This article uses a case scenario to illustrate commonly reported somatic, visceral, and neurologic symptoms and their associated health and participation impact in a female with CPP. Differential diagnosis of pain generators requires an in-depth understanding of possible anatomic and physiologic contributors to this disorder. This article provides a detailed discussion of the relevant clinical anatomy with specific attention to complex interrelationships between anatomic structures potentially leading to the patient's pain. In addition, it describes the physical therapy management specific to this case, including examination, differential diagnosis, and progression of interventions.

    Background Responses to early-life adversity may differ by sex. We investigated the sex-specific impact of early-life adversity on chronic pain, chronic multisite pain, and somatizing tendency with chronic pain. Methods We examined 4229 respondents aged 20–79 years who participated in the Pain Associated Cross-Sectional Epidemiological Survey in Japan. Outcomes were: 1) chronic pain prevalence, 2) multisite pain (≥3 sites) prevalence, and 3) multiple somatic symptoms (≥3 symptoms) among respondents with chronic pain related to the presence or absence of early-life adversity. Multivariable-adjusted odds ratios (ORs) were calculated with 95% confidence intervals using a logistic regression model including age, smoking status, exercise routine, sleep time, body mass index, household expenditure, and the full distribution of scores on the Mental Health Inventory-5. We further adjusted for pain intensity when we analyzed the data for respondents with chronic pain. Results The prevalence of chronic pain was higher among respondents reporting the presence of early-life adversity compared with those reporting its absence, with multivariable ORs of 1.62 (1.22–2.15, p<0.01) in men and 1.47 (1.13–1.90, p<0.01) in women. Among women with chronic pain, early-life adversity was associated with multisite pain and multiple somatic symptoms; multivariable ORs were 1.78 (1.22–2.60, p<0.01) for multisite pain and 1.89 (1.27–2.83, p<0.01) for ≥3 somatic symptoms. No associations were observed between early-life adversity and chronic multisite pain or multiple somatic symptoms among men with chronic pain. Conclusion Early-life adversity may be linked to a higher prevalence of chronic pain among both sexes and to multisite pain and somatizing tendency among women with chronic pain. PMID:28243147

    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.

    Chronic pain is an important public health problem that negatively impacts the quality of life of affected individuals and exacts enormous socioeconomic costs. Chronic pain is often accompanied by comorbid emotional disorders including anxiety, depression, and possibly anhedonia. The neural circuits underlying the intersection of pain and pleasure are not well understood. We summarize recent human and animal investigations and demonstrate that aversive aspects of pain are encoded in brain regions overlapping with areas processing reward and motivation. We highlight findings revealing anatomical and functional alterations of reward/motivation circuits in chronic pain. Finally, we review supporting evidence for the concept that pain relief is rewarding and activates brain reward/motivation circuits. Adaptations in brain reward circuits may be fundamental to the pathology of chronic pain. Knowledge of brain reward processing in the context of pain could lead to the development of new therapeutics for the treatment of emotional aspects of pain and comorbid conditions.

    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.

  17. Cortical plasticity as a new endpoint measurement for chronic pain

    Directory of Open Access Journals (Sweden)

    Zhuo Min

    2011-07-01

    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.

    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.

    Previous studies have shown differences in the psychosocial factors related to chronic localized pain (CLP) and chronic widespread pain (CWP). However, no studies have done an evaluation of differences between CLP and CWP from the viewpoint of family functioning. We did a cross-sectional study in a tertiary care setting to investigate possible differences in the relation of CWP and CLP to family functioning.Patients with CLP (N = 126) or CWP (N = 75) were assessed for family functioning by the Family Assessment Device (FAD) and a comparison was done. Logistic regression analysis was used to estimate associations of family functioning subscales with pain status (CWP vs CLP), controlling for demographic variables, pain variables; pain duration, pain ratings, pain disability, and psychological factors; depression, anxiety, and catastrophizing. The odds ratios (ORs) for the presence of CWP were calculated.Compared to patients with CLP, patients with CWP showed a lower functional status for Roles and Affective Involvement. The ORs for CWP were significantly higher in lower functioning Roles (OR: 2.38, 95% CI: 1.21-4.65) and Affective Involvement (OR: 2.86, 95% CI: 1.56-5.24) after adjusting for demographic variables. The significant association of CWP to Roles and Affective Involvement remained after controlling for the pain variables and psychological factors.This study shows that the families of patients with CWP have poorer family functioning than those with CLP. Our findings suggest that early identification and interventions for the family dysfunction of chronic pain patients are important to the treatment and prevention of CWP.

    Low back pain is one of the four most common disorders in all regions, and the greatest contributor to disability worldwide, adding 10.7% of total years lost due to this health state. The etiology of chronic low back pain is, in most of the cases (up to 85%), unknown or nonspecific, while the specific causes (specific spinal pathology and neuropathic/radicular disorders) are uncommon. Central sensitization has been recently recognized as a potential pathophysiological mechanism underlying a group of chronic pain conditions, and may be a contributory factor for a sub-group of patients with chronic low back pain. The purposes of this narrative review are twofold. First, to describe central sensitization and its symptoms and signs in patients with chronic pain disorders in order to allow its recognition in patients with nonspecific low back pain. Second, to provide general treatment principles of chronic low back pain with particular emphasis on pharmacotherapy targeting central sensitization.

    Full Text Available OBJECTIVE: Chronic low back pain represents a substantial cost to employers through benefits coverage and days missed due to incapacity. We sought to explore the effectiveness of Naturopathic care on chronic low back pain. METHODS: This study was a randomized clinical trial. We randomized 75 postal employees with low back pain of longer than six weeks duration to receive Naturopathic care (n = 39 or standardized physiotherapy (n = 36 over a period of 12 weeks. The study was conducted in clinics on-site in postal outlets. Participants in the Naturopathic care group received dietary counseling, deep breathing relaxation techniques and acupuncture. The control intervention received education and instruction on physiotherapy exercises using an approved education booklet. We measured low back pain using the Oswestry disability questionnaire as the primary outcome measure, and quality of life using the SF-36 in addition to low back range of motion, weight loss, and Body Mass Index as secondary outcomes. RESULTS: Sixty-nine participants (92% completed eight weeks or greater of the trial. Participants in the Naturopathic care group reported significantly lower back pain (-6.89, 95% CI. -9.23 to -3.54, p = <0.0001 as measured by the Oswestry questionnaire. Quality of life was also significantly improved in the group receiving Naturopathic care in all domains except for vitality. Differences for the aggregate physical component of the SF-36 was 8.47 (95% CI, 5.05 to 11.87, p = <0.0001 and for the aggregate mental component was 7.0 (95% CI, 2.25 to 11.75, p = 0.0045. All secondary outcomes were also significantly improved in the group receiving Naturopathic care: spinal flexion (p<0.0001, weight-loss (p = 0.0052 and Body Mass Index (-0.52, 95% CI, -0.96 to -0.08, p = 0.01. CONCLUSIONS: Naturopathic care provided significantly greater improvement than physiotherapy advice for patients with chronic low back pain. TRIAL REGISTRATION: Controlled

    Chronic craniofacial pain involves the head, face and oral cavity and is associated with significant morbidity and high levels of health care utilization. A bidirectional relationship is suggested in the literature for poor sleep and pain, and craniofacial pain and sleep are reciprocally related. We review this relationship and discuss management options. Part I reviews the relationship between pain and sleep disorders in the context of four diagnostic categories of chronic craniofacial pain: 1) primary headaches: migraines, tension-type headache (TTH), trigeminal autonomic cephalalgias (TACs) and hypnic headache, 2) secondary headaches: sleep apnea headache, 3) temporomandibular joint disorders (TMD) and 4) painful cranial neuropathies: trigeminal neuralgia, post-herpetic trigeminal neuropathy, painful post-traumatic trigeminal neuropathy (PTTN) and burning mouth syndrome (BMS). Part II discusses the management of patients with chronic craniofacial pain and sleep disorders addressing the factors that modulate the pain experience as well as sleep disorders and including both non-pharmacological and pharmacological modalities.

    Treatment of chronic non-cancer pain with opioid therapy has escalated in recent years, resulting in exploding therapeutic use and misuse of prescription opioids and multiple adverse drug events. Breakthrough pain is defined as a transient exacerbation of pain experienced by individuals who have relatively stable and adequately controlled baseline cancer pain. Further, the definition of breakthrough pain, prevalence, characteristics, implications, and treatment modalities have been extensively described for chronic cancer pain. However, the literature for breakthrough pain in chronic non-cancer pain including its terminology, prevalence, relevance, characteristics, and treatments, have been poorly described and continue to be debated. The philosophy of breakthrough pain in chronic non-cancer pain raises multiple issues leading almost all patients to be on high dose long-acting opioids, followed by supplementing with short-acting drugs, instead of treating the patients with only short-acting drugs as required. Consequently, the subject of breakthrough pain in chronic non-cancer pain is looked at with suspicion due to the lack of evidence and inherent bias associated with its evaluation, followed by escalating use and abuse of opioids. Multiple issues related to the concept of breakthrough pain in chronic non-cancer pain evolve around extensive use, overuse, misuse, and abuse of opioids. In the era of eliminating opioids or significantly curtailing their use to only appropriate indications, the concept of breakthrough pain raises multiple questions without any scientific evidence. This review illustrates that there is no significant evidence for any type of breakthrough pain in chronic non-cancer pain based on available literature, methodology utilized, and response to opioids in chronic non-cancer pain. The advocacy for increased usage of opioids in the treatment of chronic pain dates back to the liberalization of laws governing opioid prescription for the treatment

    Background: Today, chronic low back pain is one of the special challenges in healthcare. There is no unique approach to treat chronic low back pain. A variety of methods are used for the treatment of low back pain, but the effects of these methods have not yet been investigated adequately. Aim: The aim of this study was to compare the effects of Pilates and McKenzie training on pain and general health of men with chronic low back pain. Materials and Methods: Thirty-six patients with chronic low back pain were chosen voluntarily and assigned to three groups of 12 each: McKenzie group, Pilates group, and control group. The Pilates group participated in 1-h exercise sessions, three sessions a week for 6 weeks. McKenzie group performed workouts 1 h a day for 20 days. The control group underwent no treatment. The general health of all participants was measured by the General Health Questionnaire 28 and pain by the McGill Pain Questionnaire. Results: After therapeutic exercises, there was no significant difference between Pilates and McKenzie groups in pain relief (P = 0.327). Neither of the two methods was superior over the other for pain relief. However, there was a significant difference in general health indexes between Pilates and McKenzie groups. Conclusion: Pilates and McKenzie training reduced pain in patients with chronic low back pain, but the Pilates training was more effective to improve general health. PMID:28216860

    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.

    Lumbar degenerative disc disease without disc herniation, also known as discogenic pain, is an elusive diagnosis of chronic low back pain. Lumbar provocation discography and fusion surgery have been frequently utilized for several decades as the gold standards for the diagnosis and treatment of symptomatic lumbar discogenic pain, though controversial, based on conjecture, rather than evidence. In addition to lumbar fusion, various other operative and nonoperative modalities of treatments are available in managing chronic lumbar discogenic pain. This review provides an updated assessment of the management of chronic lumbar discogenic pain with a critical look at the many modalities of treatments that are currently available.

    The use of acupuncture for pain in pediatrics is a long-standing practice in Eastern cultures. Despite growing interest in the West, there has been relatively little systematic research on acupuncture for chronic pediatric pain. In particular, there is a paucity of randomized clinical trials testing the efficacy of acupuncture for chronic pain problems in pediatric populations. This commentary briefly reviews the history of acupuncture for pain and includes a summary of extant findings regarding potential mechanisms of its analgesic effects. Key areas for future research to advance the application of acupuncture to chronic pediatric pain problems are outlined.

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

    2003-11-01

    Chronic axial neck pain and cervicogenic headache are common problems, and there have been significant advances in the understanding of the etiology and treatment of each. The severity and duration of pain drives the process. For patients who have had slight to moderate pain that has been present for less than 6 months and have no significant motor loss, strength training of anterior, posterior, and interscapular muscle groups coupled with body mechanics training is prescribed. After 8 weeks, if the patient is better, exercises are continued at home or in a gym. If the patient is not better, physical therapy is continued for up to 8 more weeks. In patients with motor loss or severe pain, radiographs and magnetic resonance imaging (MRI) should be ordered at the initial visit. In patients with slight to moderate pain who are not better by 4 to 6 months, plain radiographs of the neck and MRI should be ordered. Based on the results, a spinal injection is usually prescribed. If MRI reveals spinal stenosis of the central or lateral canal, or a disc herniation, an epidural corticosteroid injection should be ordered. If the epidural provides good relief, the patient can be referred for more aggressive physical therapy and repeat the epidural as needed up to a maximum of three times. If there is no pathology within the canal, medial branch blocks and intra-articular steroid injections can be ordered based on the joints that are most tender or where disc space narrowing is greatest, or MRI or radiographs are recommended. If there is excellent relief from the medial branch block and joint injections, repeat when the steroids wear off. If there is good relief again, but pain recurs, medial branch radiofrequency neurotomy is recommended. For patients with one or two level disc degeneration that has not responded, a psychologic evaluation and discography is recommended. If there are no significant psychologic abnormalities, and one or two (rarely three) painful discs, surgical

    We examined the unique and shared contributions of pain catastrophizing, cognitive pre-sleep arousal, and somatic pre-sleep arousal, to the prediction of insomnia severity in chronic pain. Forty-eight adults with chronic pain completed self-report measures of these study variables, health, and mood. Hierarchical regression showed that pain catastrophizing accounted for unique variance in insomnia severity, independent of pain intensity, depression, restless legs symptoms, and demographics. However, when cognitive and somatic pre-sleep arousal were also taken into account, the significance of cognitive pre-sleep arousal rendered pain catastrophizing non-significant. We identify research and clinical implications of this study.

  2. Attitudes toward the use of animals in chronic versus acute pain research: results of a web-based forum.

    Science.gov (United States)

    Ormandy, Elisabeth H; Griffin, Gilly

    2016-09-01

    When asked about the use of animals in biomedical research, people often state that the research is only acceptable if pain and distress are minimised. However, pain is caused when the aim is to study pain itself, resulting in unalleviated pain for many of the animals involved. Consequently, the use of animals in pain research is often considered contentious. To date, no research has explored people's views toward different types of animal-based pain research (e.g. chronic or acute pain). This study used a web-based survey to explore people's willingness to support the use of mice in chronic versus acute pain research. The majority of the participants opposed the use of mice for either chronic (68.3%) or acute (63.1%) pain research. There was no difference in the levels of support or opposition for chronic versus acute pain research. Unsupportive participants justified their opposition by focusing on the perceived lack of scientific merit, or the existence of non-animal alternatives. Supporters emphasised the potential benefits that could arise, with some stating that the benefits outweigh the costs. The majority of the participants were opposed to pain research involving mice, regardless of the nature and duration of the pain inflicted, or the perceived benefit of the research. A better understanding of public views toward animal use in pain research may provide a stronger foundation for the development of policy governing the use of animals in research where animals are likely to experience unalleviated pain.

    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.

  5. Basolateral amygdala lesion inhibits the development of pain chronicity in neuropathic pain rats.

    Directory of Open Access Journals (Sweden)

    Zheng Li

    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.

    Objective. This article compares use of pain coping strategies among older, middle-aged, and younger adults living with chronic pain and seeks to determine whether the relationship between pain severity and coping is moderated by age. Method. Participants were 464 adults reporting chronic pain secondary to multiple sclerosis, spinal cord injury, or neuromuscular disease. Participants completed a survey including measures of pain severity and the Chronic Pain Coping Inventory. Results. After controlling for clinical and demographic variables, older adults (older than 60) reported a wider range of frequently used strategies and significantly more frequent engagement in activity pacing, seeking social support, and use of coping self-statements than did younger or middle-aged adults. Moderation analyses suggest that, for younger adults, efforts at coping generally increased with greater pain severity, whereas this relationship did not exist for older adults. Discussion. These data suggest differences in the quantity and quality of pain coping among age groups.

    This study aimed to (1) identify differences in sleep behaviors, sleep quality, pre-sleep arousal and prevalence of insomnia symptoms in adolescents with chronic pain compared to a healthy age and sex-matched cohort and (2) examine pain intensity, pubertal development, depression, and pre-sleep arousal as risk factors for insomnia symptoms. Participants included 115 adolescents, 12-18 years of age (73.0% female), 59 youth with chronic pain and 56 healthy youth. During a home-based assessment, adolescents completed validated measures of pain, sleep quality, sleep hygiene, pre-sleep arousal, depressive symptoms, and pubertal development. Findings revealed a significantly higher percentage of adolescents with chronic pain reporting symptoms of insomnia (54.2%) compared to healthy adolescents (19.6%), pinsomnia, having chronic pain (OR=6.09) and higher levels of cognitive pre-sleep arousal (OR=1.24). Level of pain intensity did not predict insomnia. While sleep disruption may initially relate to pain, these symptoms may persist into a separate primary sleep disorder over time due to other behavioral and psychosocial factors. Assessment of insomnia may be important for identifying behavioral targets for the delivery of sleep-specific interventions to youth with chronic pain.

    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).

    Agar-Wilson, M; Jackson, T

    2012-01-01

    Although emotion regulation capacities have been linked to adjustment among people with chronic pain, researchers have yet to determine whether these capacities are related to functioning independent of established facets of pain coping. The present study was designed to address this gap. A sample 128 Australian adults with chronic pain (44 men, 84 women) completed self-report measures of adjustment (quality of life, negative affect, and pain-related disability), pain coping, and features of emotion regulation (emotion appraisal, perceived efficacy in emotion regulation, emotion utilization). Hierarchical multiple regression analyses indicated that efficacy in emotion regulation was related to quality of life and reduced negative affect even after statistically controlling for effects of other measures of adjustment, pain coping efficacy, and pain coping. Conversely, features of emotion regulation did not improve the prediction model for pain-related disability. Findings suggest emotion regulation capacities may have a unique role in the prediction of specific facets of adjustment among people with chronic pain.

    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

    Psychological factors within the Fear-Avoidance Model of Musculoskeletal Pain (FAM) predict clinical and experimental pain in both symptomatic and asymptomatic individuals. Clinicians routinely examine individuals with provocative testing procedures that evoke symptoms. The purpose of this study was to investigate which FAM factors were associated with evoked pain intensity, non-painful symptom intensity, and range of motion during an upper-limb neurodynamic test. Healthy participants (n = 62) completed psychological questionnaires for pain catastrophizing, fear of pain, kinesiophobia, and anxiety prior to neurodynamic testing. Pain intensity, non-painful sensation intensity, and elbow range of motion (ROM) were collected during testing and served as dependent variables in separate simultaneous regression models. All the psychological predictors in the model accounted for 18% of the variance in evoked pain intensity (p = .02), with only pain catastrophizing (beta = .442, p neurodynamic testing for healthy subjects. Although these findings cannot be directly translated to clinical practice, the influence of pain catastrophizing on evoked pain responses should be considered during neurodynamic testing.

    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.

  17. A tool for classifying individuals with chronic back pain: using multivariate pattern analysis with functional magnetic resonance imaging data.

    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

    The combination of prescription opioid dependence and chronic pain is increasingly prevalent and hazardous to public health. Variability in pain may explain poor prescription opioid addiction treatment outcomes in persons with chronic pain. This study examined pain trajectories and pain volatility in patients with chronic pain receiving treatment for prescription opioid addiction. We conducted secondary analyses of adults with chronic pain (n = 149) who received buprenorphine/naloxone (BUP/NLX) and counseling for 12 weeks in an outpatient, multisite clinical trial. Good treatment outcome was defined as urine-verified abstinence from opioids at treatment endpoint (Week 12) and during at least 2 of the previous 3 weeks. Pain severity significantly declined over time during treatment (b = -0.36, p treatment outcome (odds ratio = 0.55, p treatment provides observational support for the analgesic effects of BUP/NLX in patients with chronic pain and opioid dependence. Patients with greater volatility in subjective pain during treatment have increased risk of returning to opioid use by the conclusion of an intensive treatment with BUP/NLX and counseling. Future research should examine underlying mechanisms of pain volatility and identify related therapeutic targets to optimize interventions for prescription opioid addiction and co-occurring chronic pain.

    Respiratory muscle strength is one parameter that is currently proposed to be affected in patients with chronic neck pain. This study was aimed at examining whether patients with chronic neck pain have reduced respiratory strength and with which neck pain problems their respiratory strength is associated. In this controlled cross-sectional study, 45 patients with chronic neck pain and 45 healthy well-matched controls were recruited. Respiratory muscle strength was assessed through maximal mouth pressures. The subjects were additionally assessed for their pain intensity and disability, neck muscle strength, endurance of deep neck flexors, neck range of movement, forward head posture and psychological states. Paired t-tests showed that patients with chronic neck pain have reduced Maximal Inspiratory (MIP) (r = 0.35) and Maximal Expiratory Pressures (MEP) (r = 0.39) (P Neck muscle strength (r > 0.5), kinesiophobia (r neck pain and disability (r Neck muscle strength was the only predictor that remained as significant into the prediction models of MIP and MEP. It can be concluded that patients with chronic neck pain present weakness of their respiratory muscles. This weakness seems to be a result of the impaired global and local muscle system of neck pain patients, and psychological states also appear to have an additional contribution. Clinicians are advised to consider the respiratory system of patients with chronic neck pain during their usual assessment and appropriately address their treatment.

  20. Mechanism of Chronic Pain in Rodent Brain Imaging

    Chang, Pei-Ching

    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.

    The use of unidimensional scales to measure pain intensity has been criticised because of the multidimensional nature of pain. We conducted multiple linear regression analyses to determine which dimensions of pain--sensory versus affective--predicted scores on unidimensional scales measuring pain intensity and emotions in 109 Italian women suffering from chronic, non-malignant musculoskeletal pain. We then compared the results with earlier findings in two groups of cancer patients suffering from acute post-operative pain and chronic cancer-related pain, respectively. Age, physical capacity and scores on the multidimensional affect and pain survey (MAPS) were used to predict patients' ratings on one visual analogue scale (VAS) and three numerical rating scales (NRS) measuring pain intensity, anxiety and depressed mood. Unidimensional pain intensity ratings were predicted better from sensory than from affective pain predictors, and the affective predictors made no unique contribution (NRS), or only a very small one (VAS). Both sensory and emotional pain aspects were unique predictors of NRS anxiety and depression. Therefore, in contrast to earlier findings in two different types of cancer patients, in subjects affected by chronic non-malignant musculoskeletal pain, the scores on unidimensional pain intensity scales mainly reflect sensory pain dimensions, supporting the discriminant validity of the NRS and VAS used. However, the patients had some difficulty in distinguishing between sensory and emotional information. For this reason, several unidimensional scales to rate pain intensity and emotions separately should be used to obtain a complete picture of the status and needs of any given patient.

    Background: Prevalence of musculoskeletal pain among adolescents is high, and pain in adolescence increases the risk of chronic pain in adulthood. Studies have shown conflicting evidence regarding associations between physical activity and musculoskeletal pain, and few have evaluated the potential impact of sport participation on musculoskeletal pain in adolescent population samples. Purpose: To examine the associations between physical activity level, sport participation, and musculoskeletal pain in the neck and shoulders, low back, and lower extremities in a population-based sample of adolescents. Study Design: Cross-sectional study; Level of evidence 4. Methods: Data from the Nord-Trøndelag Health Study (Young-HUNT3) were used. All 10,464 adolescents in the Nord-Trøndelag county of Norway were invited, of whom 74% participated. Participants were asked how often they had experienced pain, unrelated to any known disease or acute injury, in the neck and shoulders, low back, and lower extremities in the past 3 months. The associations between (1) physical activity level (low [reference], medium or high) or (2) sport participation (weekly compared with no/infrequent participation) and pain were evaluated using logistic regression analyses, stratified by sex, and adjusted for age, socioeconomic status, and psychological distress. Results: The analyses included 7596 adolescents (mean age, 15.8 years; SD, 1.7). Neck and shoulder pain was most prevalent (17%). A moderate level of physical activity was associated with reduced odds of neck and shoulder pain (OR = 0.79 [95% CI, 0.66-0.94]) and low back pain (OR = 0.75 [95% CI, 0.62-0.91]), whereas a high level of activity increased the odds of lower extremity pain (OR = 1.60 [95% CI, 1.29-1.99]). Participation in endurance sports was associated with lower odds of neck and shoulder pain (OR = 0.79 [95% CI, 0.68-0.92]) and low back pain (OR = 0.77 [95% CI, 0.65-0.92]), especially among girls.

    2014-01-01

    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.

    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.

    Simons, Laura; Elman, Igor; Borsook, David

    2014-01-01

    Our understanding of chronic pain involves complex brain circuits that include sensory, emotional, cognitive and interoceptive processing. The feed-forward interactions between physical (e.g., trauma) and emotional pain and the consequences of altered psychological status on the expression of pain have made the evaluation and treatment of chronic pain a challenge in the clinic. By understanding the neural circuits involved in psychological processes, a mechanistic approach to the implementation of psychology-based treatments may be better understood. In this review we evaluate some of the principle processes that may be altered as a consequence of chronic pain in the context of localized and integrated neural networks. These changes are ongoing, vary in their magnitude, and their hierarchical manifestations, and may be temporally and sequentially altered by treatments, and all contribute to an overall pain phenotype. Furthermore, we link altered psychological processes to specific evidence-based treatments to put forth a model of pain neuroscience psychology. PMID:24374383

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. Results: We identified six prospective longitudinal studies with small-to-mid-sized samples that met the inclusion criteria.

    This study reports the results of a researcher-administered survey with 115 patients receiving chronic opioid therapy (>90 days) to obtain information regarding how chronic opioid therapy was started. Chronic opioids were started after surgery (27.0%, 95% confidence interval [CI], 18.5-35.5) or for the treatment of acute injury-related pain (27.0%, 95% CI, 18.5-35.5). Many who initiated opioid therapy after surgery reported postoperative complications (61.3%, 95% CI, 50.8-71.8) and many with injury-related pain reported follow-up corrective surgery (58.1%, 95% CI, 47.5-68.7), which led to the continuation of opioids. A large percentage of patients had concurrent depression (43.5%, 95% CI, 34.0-53.0) and anxiety (23.5%, 95% CI, 15.3-31.7). Many participants had a medical history of aberrant drug-related behavior (32.5%, 95% CI, 23.5-41.5) and self-reported history of addiction (21.7%, 95% CI, 13.7-29.7). Almost one-quarter reported taking opioids for a different indication than that for which opioids were started (95% CI, 26.6-45.0). Patients receiving long-term opioid therapy often transitioned to chronic use after starting opioids for the short-term treatment of postoperative or injury-related pain. It is not evident if a clear decision to continue opioids on a chronic basis was made. This survey provides insight as to how chronic opioid therapy is started, and may suggest opportunities for improved patient selection for opioid therapy.

  16. Midgut malrotation with chronic abdominal pain

    Full Text Available Abnormalities in midgut rotation occur during the physiological herniation of midgut between the 5 th and 10 th week of gestation. The most significant abnormality is narrow small bowel mesentery which is prone to volvulus. This occurs most frequently in the neonatal period, less commonly midgut malrotation presents in adulthood with either acute volvulus or chronic abdominal symptoms. It is the latter group that represents a diagnostic challenge. We report a case of a 17-year-old male patient who presented with 10-year history of nonspecific gastro-intestinal symptoms. After extensive investigation the patient was diagnosed with midgut malrotation following computed tomography of abdomen. The patient was treated with a laparoscopic Ladd′s procedure and at 3 months he was gaining weight and had stopped vomiting. A laparoscopic Ladd′s procedure is an acceptable alternative to the open technique in treating symptomatic malrotation in adults. Midgut malrotation is a rare congenital anomaly which may present as chronic abdominal pain. Abdominal CT is helpful for diagnosis.

    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

    Chronic pain negatively impacts health, well-being, and social participation. Effective rehabilitation often hinges on long-term changes in pain-related perceptions and behaviors. However, there are important gaps in understanding how patients perceive these changes. The present pilot study addresses this gap by using qualitative and quantitative methodologies to explore how patients perceive and experience changes in function, participation, and pain-related factors following a chronic pain rehabilitation program. A mixed-method design was used in which the core method was qualitative. Descriptive quantitative data was used to further characterize the sample. Semistructured interviews were conducted 1–6 months following treatment completion. Questionnaires were administered before and after treatment and at follow-up. Interview data was analyzed thematically. Participants' individual descriptive data was compared to established cut-scores and criteria for change. A major theme of personal growth emerged in the qualitative analysis. Participants also discussed the factors that facilitated personal growth and the ongoing challenges to this growth. The quantitative data revealed limited improvement on measures of pain, disability, catastrophizing, and depression. These findings suggest that, despite limited improvement on treatment-related questionnaires, patients can experience an important and enduring sense of personal growth. Clinical and theoretical implications are discussed. PMID:28070161

  1. A neural model for chronic pain and pain relief by extracorporeal shock wave treatment.

    2008-12-01

    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.

  3. Could stress contribute to pain-related fear in chronic pain?

    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.

    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

    Chronic pain is a debilitating syndrome caused by a variety of disorders, and represents a major clinical problem because of the lack of adequate medication. In chronic pain, massive changes in gene expression are observed in a variety of cells, including neurons and glia, in the overall somatosensory system from the sensory ganglia to the higher central nervous system. The protein expressions of hundreds of genes are thought to be post-transcriptionally regulated by a single type of microRNA in a sequence-specific manner. Recently, critical roles of microRNAs in the pathophysiology of chronic pain have been emerging. Genome-wide screenings of microRNA expression changes have been reported in a variety of painful conditions, including peripheral nerve injury, inflammatory diseases, cancer and spinal cord injury. The data obtained suggest that a wide range of microRNAs change their expressions in individual pain conditions, although the pathological significance of individual microRNAs as causal mediators in distinct pain conditions remains to be revealed for a limited number of microRNAs. Insights into the roles of microRNAs in chronic pain will enhance our understanding of the pathophysiology of chronic pain and allow prompt therapeutic application of microRNA-related drugs against intractable persistent pain.

    Full Text Available The treatment of young people with chronic pain is a complex endeavor. Many of these youth do not obtain adequate relief from available interventions. Psychological neuromodulatory treatments have been shown to have potential benefit for adults with chronic pain. Here, we review and summarize the available information about the efficacy of three promising psychological neuromodulatory treatments—neurofeedback, meditation and hypnosis—when provided to young people with chronic pain. A total of 16 articles were identified and reviewed. The findings from these studies show that hypnotic treatments are effective in reducing pain intensity for a variety of pediatric chronic pain problems, although research suggests variability in outcomes as a function of the specific pain problem treated. There are too few studies evaluating the efficacy of neurofeedback or meditation training in young people with chronic pain to draw firm conclusions regarding their efficacy. However, preliminary data indicate that these treatments could potentially have positive effects on a variety of outcomes (e.g., pain intensity, frequency of pain episodes, physical and psychological function, at least in the short term. Clinical trials are needed to evaluate the effects of neurofeedback and meditation training, and research is needed to identify the moderators of treatment benefits as well as better understand the mechanisms underlying the efficacy of all three of these treatments. The findings from such research could enhance overall treatment efficacy by: (1 providing an empirical basis for better patient-treatment matching; and (2 identifying specific mechanisms that could be targeted with treatment.

    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 neck pain. The results support the use of DDN in the management of myofascial pain syndrome in people with chronic nonspecific neck pain.

    Full Text Available Abstract Background Facet joints are a clinically important source of chronic cervical, thoracic, and lumbar spine pain. The purpose of this study was to systematically evaluate the prevalence of facet joint pain by spinal region in patients with chronic spine pain referred to an interventional pain management practice. Methods Five hundred consecutive patients with chronic, non-specific spine pain were evaluated. The prevalence of facet joint pain was determined using controlled comparative local anesthetic blocks (1% lidocaine or 1% lidocaine followed by 0.25% bupivacaine, in accordance with the criteria established by the International Association for the Study of Pain (IASP. The study was performed in the United States in a non-university based ambulatory interventional pain management setting. Results The prevalence of facet joint pain in patients with chronic cervical spine pain was 55% 5(95% CI, 49% – 61%, with thoracic spine pain was 42% (95% CI, 30% – 53%, and in with lumbar spine pain was 31% (95% CI, 27% – 36%. The false-positive rate with single blocks with lidocaine was 63% (95% CI, 54% – 72% in the cervical spine, 55% (95% CI, 39% – 78% in the thoracic spine, and 27% (95% CI, 22% – 32% in the lumbar spine. Conclusion This study demonstrated that in an interventional pain management setting, facet joints are clinically important spinal pain generators in a significant proportion of patients with chronic spinal pain. Because these patients typically have failed conservative management, including physical therapy, chiropractic treatment and analgesics, they may benefit from specific interventions designed to manage facet joint pain.

Mechanisms of chronic pain in OA have not been fully investigated yet.Objective: to study key mechanisms of chronic pain in patients with knee OA.Subjects and methods. Authors examined 80 women aged 45–65 years, with chronic pain due to OA of the knee. Clinical rheumatologic and neurologic examinations, screening for neuropathic pain (PainDETECT and DN4 questionnaires, estimation of duration and intensity of pain, WOMAC assessment and evaluation of affective disorders (HADS questionnaire were performed.

According to DN4 questionnaire, 25 (30% patients scored 4 and more, i. e. had signs of neuropathic pain, whereas 55 (70% did not (scored less than 4. Although neurologic examination did not reveal lesions of somatosensory system in neither of groups, assessment of the pain sensitivity showed hyperalgesia in 60% of cases. Patients with signs of neuropathic pain typically have secondary hyperalgesia propagating far from the damaged joint.Conclusion. 30% of patients with osteoarthritis have pain of different intensity determined by nociceptive and neuropathic mechanisms. At the same time the absence of lesions of somatosensory system does not let us to consider the pain neuropathic and indicates that it has dysfunctional nature. Signs of neuropathic pain associated with secondary hyperalgesia may be a clinical symptom of central sensitization. Due to this fact, reasonable therapy of osteoarthritis-associated chronic pain should include, besides NSAIDs, central acting drugs for neuropathic pain treatment.

    Background and aims Prism adaptation (PA) is a non-invasive procedure in which participants perform a visuo-motor pointing task while wearing prism goggles inducing a lateral displacement of the visual field and a mismatch between the seen and felt position of the pointing hand. PA is thought to induce a reorganization of sensorimotor coordination, and has been used successfully to rehabilitate neglect following right-hemisphere lesions. Because studies have shown that complex regional pain syndrome (CRPS) is associated with neglect-like symptoms, it was proposed that PA could be used to alleviate pain in these patients. Database A search for peer-reviewed articles on neglect-like symptoms in CRPS and on the use of prisms in CRPS was conducted using the PubMed database. Results There is still no agreement as to whether CRPS patients really present neglect symptoms and, if they do, what it is that they neglect. Furthermore, there is insufficient data to determine whether PA exerts an effect on CRPS symptoms. Finally, it remains unknown whether neglect can be observed in other types of lateralized pain, or whether PA could be useful for these patients. Conclusion By highlighting open issues, our review provides guidelines for future studies on the use of prisms in pain. The assessment of neglect in patients with CRPS as well as other types of lateralized chronic pain should be characterized using a combination of neuropsychological methods assessing the multiple aspects of neglect in a more refined manner. In addition, further studies should investigate the mechanisms through which PA may modulate pain. PMID:26095341

    Full Text Available Abstract Background Neck-shoulder pain conditions, e.g., chronic trapezius myalgia, have been associated with sensory disturbances such as increased sensitivity to experimentally induced pain. This study investigated pain sensitivity in terms of bilateral pressure pain thresholds over the trapezius and tibialis anterior muscles and pain responses after a unilateral hypertonic saline infusion into the right legs tibialis anterior muscle and related those parameters to intensity and area size of the clinical pain and to psychological factors (sleeping problems, depression, anxiety, catastrophizing and fear-avoidance. Methods Nineteen women with chronic non-traumatic neck-shoulder pain but without simultaneous anatomically widespread clinical pain (NSP and 30 age-matched pain-free female control subjects (CON participated in the study. Results NSP had lower pressure pain thresholds over the trapezius and over the tibialis anterior muscles and experienced hypertonic saline-evoked pain in the tibialis anterior muscle to be significantly more intense and locally more widespread than CON. More intense symptoms of anxiety and depression together with a higher disability level were associated with increased pain responses to experimental pain induction and a larger area size of the clinical neck-shoulder pain at its worst. Conclusion These results indicate that central mechanisms e.g., central sensitization and altered descending control, are involved in chronic neck-shoulder pain since sensory hypersensitivity was found in areas distant to the site of clinical pain. Psychological status was found to interact with the perception, intensity, duration and distribution of induced pain (hypertonic saline together with the spreading of clinical pain. The duration and intensity of pain correlated negatively with pressure pain thresholds.

    Analysis of the human microbiome continues to reveal new and previously unrealized associations between microbial dysbiosis and disease. Novel approaches to bacterial identification using culture-independent methods allow practitioners to discern the presence of alterations in the taxa and diversity of the microbiome and identify correlations with disease processes. While some of these diseases that have been extensively studied are well-defined in their etiology and treatment methods (colorectal cancer), others have provided much more significant challenges in both diagnosis and treatment. One such condition, chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), has several etiological and potentiating contributions from infection, inflammation, central nervous system (CNS) changes, stress, and central sensitization-all factors that play important roles in the crosstalk between the human body and its microbiome. No singular cause of CP/CPPS has been identified and it is most likely a syndrome with multifactorial causes. This heterogeneity and ambiguity are sources of significant frustration for patients and providers alike. Despite multiple attempts, treatment of chronic prostatitis with monotherapy has seen limited success, which is thought to be due to its heterogeneous nature. Phenotypic approaches to both classify the disease and direct treatment for CP/CPPS have proven beneficial in these patients, but questions still remain regarding etiology. Newer microbiome research has found correlations between symptom scores and disease severity and the degree of dysbiosis in urine and gut (stool) microbiomes in these patients as compared to un-afflicted controls. These findings present potential new diagnostic and therapeutic targets in CP/CPPS patients.

    1994-01-01

    Chronic back pain is a major consumer of costly healthcare resources in the Western world. Patients' suffering affects their families and associates, leads to diminished self-confidence, and prevents their effective participation in the workplace. Although medical treatments and analgesics are generally successful in treating acute back pain, and some patients recover spontaneously, conventional approaches are less successful in dealing with chronic pain and may be contraindicated. In the first of two articles, the author offers an overview of research on cognitive-behavioral programs, using operant activity and relaxation training, that have led to reductions in patients' pain and to increases in their activity levels. Part 2 provides a step-by-step description of how to incorporate basic psychological techniques and physical therapy procedures for chronic pain sufferers. Patient and therapist cooperate in operant activities, with the patient monitoring progress and carrying out regular home-work assignments as he or she seeks to perform target activities; applied relaxation encourages the patient to cope with pain by disrupting the connection between anxiety, despair, and pain. The techniques outlined are suitable for dealing with other musculoskeletal conditions as well as with chronic back pain.

    There has been an increase in the number of chronic pain clinical trials in which the treatments being evaluated did not differ significantly from placebo in the primary efficacy analyses despite previous research suggesting that efficacy could be expected. These findings could reflect a true lack of efficacy or methodological and other aspects of these trials that compromise the demonstration of efficacy. There is substantial variability among chronic pain clinical trials with respect to important research design considerations, and identifying and addressing any methodological weaknesses would enhance the likelihood of demonstrating the analgesic effects of new interventions. An IMMPACT consensus meeting was therefore convened to identify the critical research design considerations for confirmatory chronic pain trials and to make recommendations for their conduct. We present recommendations for the major components of confirmatory chronic pain clinical trials, including participant selection, trial phases and duration, treatment groups and dosing regimens, and types of trials. Increased attention to and research on the methodological aspects of confirmatory chronic pain clinical trials has the potential to enhance their assay sensitivity and ultimately provide more meaningful evaluations of treatments for chronic pain.

    People aged 65 years and over make up the fastest growing demographic in the United States. By the year 2040 they will comprise approximately one fourth of the US population. The elderly patient in need of chronic pain therapy presents challenges best met with an enlightened and effective treatment strategy. Practice standards must include a thorough pain assessment and formation of a multimodal care plan, which applies knowledge of pain management in an objective and scientific manner. In this article, a patient case study illustrates how the appropriate management of chronic pain in an elderly patient can lead to better clinical outcomes.

    The primary purpose of the present study was to examine the temporal stability of communicative and protective pain behaviors in patients with chronic back pain. The study also examined whether the stability of pain behaviors could be accounted for by patients' levels of pain severity, catastrophizing, or fear of movement. Patients (n=70) were filmed on two separate occasions (i.e., baseline, follow-up) while performing a standardized lifting task designed to elicit pain behaviors. Consistent with previous studies, the results provided evidence for the stability of pain behaviors in patients with chronic pain. The analyses indicated that communicative and protective pain behavior scores did not change significantly from baseline to follow-up. In addition, significant test-retest correlations were found between baseline and follow-up pain behavior scores. The results of hierarchical multiple regression analyses further showed that pain behaviors remained stable over time even when accounting for patients' levels of pain severity. Regression analyses also showed that pain behaviors remained stable when accounting for patients' levels of catastrophizing and fear of movement. Discussion addresses the potential contribution of central neural mechanisms and social environmental reinforcement contingencies to the stability of pain behaviors. The discussion also addresses how treatment interventions specifically aimed at targeting pain behaviors might help to augment the overall impact of pain and disability management programs.

    The physical and psychological factors associated with reduction of disability after aquatic exercise are not well understood. Sixty participants (30 men and 30 women; age, 50.60 [9.69] yrs; body mass index, 27.21 [5.20] kg/m²) with chronic low back pain were prospectively recruited. The 8-wk aquatic therapy program was carried out in an indoor pool sized 25 × 6 m, with 140-cm water depth and 30°C (1°C) of water temperature, where patients exercised for 2-5 days a week. Each aquatic exercise session lasted 55-60 mins (10 mins of warm-up, 20-25 mins of aerobic exercise, 15-20 mins of resistance exercise, and 10 mins of cooldown). Demographic information, disability (Oswestry Disability Index), back pain (visual analog scale), quality-of-life (Short Form 36), abdominal muscular endurance (curl-up), handgrip strength, trunk flexion and hamstring length (sit and reach), resting heart rate, and body mass index were outcomes variables. Significant correlations between change in disability and visual analog scale (at rest, flexion, and extension), curl-up and handgrip (r ranged between -0.353 and 0.582, all Ps < 0.01) were found. Changes in pain and abdominal muscular endurance were significant predictors of change in disability after therapy.

    Full Text Available 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.

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

  11. Change Narratives That Elude Quantification: A Mixed-Methods Analysis of How People with Chronic Pain Perceive Pain Rehabilitation

    Directory of Open Access Journals (Sweden)

    Timothy H. Wideman

    2016-01-01

    Full Text Available Chronic pain negatively impacts health, well-being, and social participation. Effective rehabilitation often hinges on long-term changes in pain-related perceptions and behaviors. However, there are important gaps in understanding how patients perceive these changes. The present pilot study addresses this gap by using qualitative and quantitative methodologies to explore how patients perceive and experience changes in function, participation, and pain-related factors following a chronic pain rehabilitation program. A mixed-method design was used in which the core method was qualitative. Descriptive quantitative data was used to further characterize the sample. Semistructured interviews were conducted 1–6 months following treatment completion. Questionnaires were administered before and after treatment and at follow-up. Interview data was analyzed thematically. Participants’ individual descriptive data was compared to established cut-scores and criteria for change. A major theme of personal growth emerged in the qualitative analysis. Participants also discussed the factors that facilitated personal growth and the ongoing challenges to this growth. The quantitative data revealed limited improvement on measures of pain, disability, catastrophizing, and depression. These findings suggest that, despite limited improvement on treatment-related questionnaires, patients can experience an important and enduring sense of personal growth. Clinical and theoretical implications are discussed.

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.

    2014-04-01

    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.

    2015-04-01

    Unlike acute pain that warns us of injury or disease, chronic or persistent pain serves no adaptive purpose. Though there is no agreed on definition of chronic pain, it is commonly referred to as pain that is without biological value, lasting longer than the typical healing time, not responsive to treatments based on specific remedies, and of a duration greater than 6 months. Chronic pain that is severe and intractable has detrimental consequences, including psychological distress, job loss, social isolation, and, not surprisingly, it is highly comorbid with depression and anxiety. Historically, pain without an apparent anatomical or neurophysiological origin was labelled as psychopathological. This approach is damaging to the patient and provider alike. It pollutes the therapeutic relationship by introducing an element of mutual distrust as well as implicit, if not explicit, blame. It is demoralizing to the patient who feels at fault, disbelieved, and alone. Moreover, many medically unexplained pains are now understood to involve an interplay between peripheral and central neurophysiological mechanisms that have gone awry. The new Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, somatic symptom disorder overpsychologizes people with chronic pain; it has low sensitivity and specificity, and it contributes to misdiagnosis, as well as unnecessary stigma. Adjustment disorder remains the most appropriate, accurate, and acceptable diagnosis for people who are overly concerned about their pain.

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.

    Autism spectrum disorder is a debilitating mental illness and social issue. Autism spectrum disorder patients suffer from social isolation, cognitive deficits, compulsive behavior, and sensory deficits, including hyposensitivity to pain. However, recent studies argued that autism spectrum disorder patients show physiological pain response and, in some cases, even extremely intense pain response to harmless stimulation. Recently, Shank gene family was reported as one of the genetic risk factors of autism spectrum disorder. Thus, in this study, we used Shank2(-) (/) (-) (Shank2 knock-out, KO) mice to investigate the controversial pain sensitivity issue and found that Shank2 KO mice showed reduced tactile perception and analgesia to chronic pain.

    For drug therapy a differentiation of acute and chronic pain is essential. In emergency situations of acute abdominal pain a fast diagnosis is mandatory. Analgesia should be provided as soon as possible. The different groups of analgesics should be used according to their known effects, side effects and contraindications. Postoperative pain after abdominal surgery has to be considered as a special condition of acute abdominal pain. Main treatment options are non opioid analgesics and opioids. Opioids can be administered intravenously via patient controlled analgesia (PCA) devices. In major abdominal surgery neuroaxial analgesia, preferentially administered via an epidural catheter provides excellent pain relief with positive impact on gastrointestinal motility and patients' recovery. Because of difficulties to allocate chronic abdominal pain to a specific organ, causal treatment often turns out to be difficult. Peripheral and central sensitization, as well as an alteration of the endogenous pain modulation comes to the fore in these chronic pain conditions. Co-analgesics like anticonvulsants and antidepressants are utilized to reduce sensitization and improve the endogenous pain modulating system. Non drug approaches and alternative treatment options might be useful. In contrast, orally or transcutaneously administered opioids are the principal corner stone for the treatment of cancer pain.

Objectives The present study aimed to understand this management process and its setbacks in the elderly. Materials and Methods The grounded theory approach using unstructured interviews and observation of participants were the main methods for data collection. Study participants consisted of 30 old people with chronic pain, 3 relatives, and 29 health care providers selected with purposive and theoretical sampling methods in Ahvaz. Sampling was continued until data saturation reached. Data analysis was performed concurrently with data gathering based on Strauss and Corbin’s proposed method. Data rigor (trustworthiness was confirmed by Lincoln and Gubba’s approach. Results Vulnerability was one of major themes extracted as parts of a Grounded Theory study results, which composed of three categories: functional impairment, disability, and limitations. Many participants had functional impairment in their mood and emotional, social, and psychological aspects and encountered a series of disabilities for doing their daily activities. Moreover, they had limitations in physical as well as environmental aspects, all of them influenced their pain management. Conclusions Chronic pain in the elderly has often been assessed and treated inadequately; therefore, attention to their problems and limitations may be useful in developing a comprehensive caring program and managing effectively their chronic pain.

  4. Phenomenology, Hypnosis, and Chronic Pain: Steps for Clinical Understanding

    2014-04-01

    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.

    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.

    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.

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

    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.

  18. DNA methylation of SPARC and chronic low back pain

    2011-08-01

    Full Text Available Abstract Background The extracellular matrix protein SPARC (Secreted Protein, Acidic, Rich in Cysteine has been linked to degeneration of the intervertebral discs and chronic low back pain (LBP. In humans, SPARC protein expression is decreased as a function of age and disc degeneration. In mice, inactivation of the SPARC gene results in the development of accelerated age-dependent disc degeneration concurrent with age-dependent behavioral signs of chronic LBP. DNA methylation is the covalent modification of DNA by addition of methyl moieties to cytosines in DNA. DNA methylation plays an important role in programming of gene expression, including in the dynamic regulation of changes in gene expression in response to aging and environmental signals. We tested the hypothesis that DNA methylation down-regulates SPARC expression in chronic LBP in pre-clinical models and in patients with chronic LBP. Results Our data shows that aging mice develop anatomical and behavioral signs of disc degeneration and back pain, decreased SPARC expression and increased methylation of the SPARC promoter. In parallel, we show that human subjects with back pain exhibit signs of disc degeneration and increased methylation of the SPARC promoter. Methylation of either the human or mouse SPARC promoter silences its activity in transient transfection assays. Conclusions This study provides the first evidence that DNA methylation of a single gene plays a role in chronic pain in humans and animal models. This has important implications for understanding the mechanisms involved in chronic pain and for pain therapy.

    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.

    The purpose of this randomized noninferiority trial was to compare video teleconferencing (VTC) versus in-person (IP) delivery of an 8-week acceptance and commitment therapy (ACT) intervention among veterans with chronic pain (N = 128) at post-treatment and at 6-month follow-up. The primary outcome was the pain interference subscale of the Brief Pain Inventory. Secondary outcomes included measures of pain severity, mental and physical health-related quality of life, pain acceptance, activity level, depression, pain-related anxiety, and sleep quality. In intent to treat analyses using mixed linear effects modeling, both groups exhibited significant improvements on primary and secondary outcomes, with the exception of sleep quality. Further, improvements in activity level at 6-month follow-up were significantly greater in the IP group. The noninferiority hypothesis was supported for the primary outcome and several secondary outcomes. Treatment satisfaction was similar between groups; however, significantly more participants withdrew during treatment in the VTC group compared with the IP group, which was moderated by activity level at baseline. These findings generally suggest that ACT delivered via VTC can be as effective and acceptable as IP delivery for chronic pain. Future studies should examine the optimal delivery of ACT for patients with chronic pain who report low levels of activity. This trial was registered at ClinicalTrials.gov (NCT01055639).

    The Pain and Interoception Imaging Network (PAIN) repository (painrepository.org) is a newly created NIH (NIDA/NCCAM) funded neuroimaging data repository that aims to accelerate scientific discovery regarding brain mechanisms in pain and to provide more rapid benefits to pain patients through the harmonization of efforts and data sharing. The PAIN Repository consists of two components, an Archived Repository and a Standardized Repository. Similar to other 'open' imaging repositories, neuroimaging researchers can deposit any dataset of chronic pain patients and healthy controls into the Archived Repository. Scans in the Archived Repository can be very diverse in terms of scanning procedures and clinical metadata, complicating the merging of datasets for analyses. The Standardized Repository overcomes these limitations through the use of standardized scanning protocols along with a standardized set of clinical metadata, allowing an unprecedented ability to perform pooled analyses. The Archived Repository currently includes 741 scans and is rapidly growing. The Standardized Repository currently includes 433 scans. Pain conditions currently represented in the PAIN repository include: irritable bowel syndrome, vulvodynia, migraine, chronic back pain, and inflammatory bowel disease. Both the PAIN Archived and Standardized Repositories promise to be important resources in the field of chronic pain research. The enhanced ability of the Standardized Repository to combine imaging, clinical and other biological datasets from multiple sites in particular make it a unique resource for significant scientific discoveries.

    Low back pain is a significant public health problem and one of the most commonly reported reasons for the use of Complementary Alternative Medicine. A randomized control trial was conducted in subjects with non-specific chronic low back pain comparing Iyengar yoga therapy to an educational control group. Both programs were 16 weeks long. Subjects were primarily self-referred and screened by primary care physicians for study of inclusion/exclusion criteria. The primary outcome for the study was functional disability. Secondary outcomes including present pain intensity, pain medication usage, pain-related attitudes and behaviors, and spinal range of motion were measured before and after the interventions. Subjects had low back pain for 11.2+/-1.54 years and 48% used pain medication. Overall, subjects presented with less pain and lower functional disability than subjects in other published intervention studies for chronic low back pain. Of the 60 subjects enrolled, 42 (70%) completed the study. Multivariate analyses of outcomes in the categories of medical, functional, psychological and behavioral factors indicated that significant differences between groups existed in functional and medical outcomes but not for the psychological or behavioral outcomes. Univariate analyses of medical and functional outcomes revealed significant reductions in pain intensity (64%), functional disability (77%) and pain medication usage (88%) in the yoga group at the post and 3-month follow-up assessments. These preliminary data indicate that the majority of self-referred persons with mild chronic low back pain will comply to and report improvement on medical and functional pain-related outcomes from Iyengar yoga therapy.

    Full Text Available OBJECTIVE: The aim of the study was to investigate the therapeutic efficacy of transcutaneous electrical nerve stimulation (TENS in the symptomatic management of chronic prostatitis pain/chronic pelvic pain syndrome. DESIGN: A pretest, posttest randomized double blind design was used in data collection. PARTICIPANT: Twenty-four patients diagnosed with chronic prostatitis- category IIIA and IIIB of the National Institute of Health Chronic Pain (NIH-CP were referred for physiotherapy from the Urology department. Intervention: Pre treatment pain level was assessed using the NIH-CP (pain domain index. The TENS group received TENS treatment, 5 times per week for a period of 4 weeks (mean treatment frequency, intensity, pulse width and duration of 60Hz, 100µS, 25mA and 20 minutes respectively. The Analgesic group received no TENS treatment but continued analgesics; the Control group received no TENS and Analgesic but placebo. All subjects were placed on antibiotics throughout the treatment period. Outcome measures: Post-treatment pain level was also assessed using NIH-CP pain index. RESULT: Findings of the study revealed significant effect of TENS on chronic prostatitis pain at p < 0.05. CONCLUSION: TENS is an effective means of non-invasive symptomatic management of chronic prostatitis pain.

    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.

    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 neck disability in computer workers is explained by the association among neck pain, TMD and unfavourable workplace conditions. Consequently, this study attempted to emphasise the importance of considering work activity for minimising neck pain-related disability.

    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.

    2013-01-01

    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.

    Background and purpose Perceived injustice has been defined as an appraisal regarding the severity and irreparability of loss associated with pain, blame and a sense of unfairness. Recent findings have identified perceived injustice as an important risk factor for pain-related outcomes. Studies suggest that perceived injustice is associated with opioid prescription in patients with pain conditions. However, the mechanisms by which perceived injustice is linked to opioid prescription are not well understood. The primary objective of this study was to examine the potential mediating roles of pain intensity, depressive symptoms and pain behavior in the association between perceived injustice and opioid prescription among patients with chronic pain. Methods This cross-sectional study used a sample of 344 patients with chronic pain being treated at a tertiary pain treatment center. Participants completed measures of perceived injustice, pain intensity, depressive symptoms, pain behavior and opioid prescription. Bootstrapped multiple mediation analyses were used to examine the mediating role of patients’ pain intensity, depressive symptoms and pain behavior in the association between perceived injustice and opioid prescription. Results Consistent with previous research, we found a significant association between perceived injustice and opioid prescription. Interestingly, results revealed that pain behavior was the only variable that mediated the association between perceived injustice and opioid prescription. Conclusion This study was the first to examine the mechanisms by which perceived injustice is associated with opioid prescription in patients with chronic pain. We found that pain behavior, rather than pain intensity and depressive symptoms, mediated the association between perceived injustice and opioid prescription. Future research in this area should employ a longitudinal research design in order to arrive at clearer causal conclusions about the relationships

In contrast to previous research, we were interested not only in specific pain coping but also in more general stress coping strategies and their potential influence on pain outcomes. Analyses were performed using correlation and regression analyses. “Praying and hoping” turned out to be an independent predictor of higher pain intensity and higher anxiety levels, whereas both “coping self-instructions” and “diverting attention” were associated with higher well-being, less feelings of helplessness, and less depression and anxiety. We further found a link between “focusing on and venting emotions” and “worse pain adjustment”. No significant relationship between dyadic coping and social support with any of our pain outcomes could be observed. Overall, our results indicate that individual coping strategies outweigh the effects of social support and dyadic coping on pain-related outcomes and pain adjustment.

    2015-10-01

    Full Text Available 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 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 profi le, particularly concerning side effects, compared to traditional opioids. This novel analgesic represents a possible therapeutic option also in the rheumatologic fi eld, particularly in the treatment of osteoarthritis and low back pain.

    We approach the problem about relationships between personality dimensions and the use of coping strategies in chronic pain patients. The most frequently used theoretical model in the area of stress and its relation to pain is the transactional model, taking into account that the incorporation of personality traits improves predictions via coping in the stress process. Following the Big Five model, the relationships between personality and coping strategies in patients with chronical neuropathic pain were established. The results showed slight relationships between the Big-Five dimensions and coping. A vulnerable personality profile in patients with chronic neuropathic pain was obtained, consisting of high neuroticism, low extraversion, openness to experience and responsibility, and moderate agreeableness.

    Individuals with chronic widespread pain, including those with fibromyalgia, pose a particular challenge to treatment, given the modest effectiveness of pharmacological agents for this condition. The growing consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. Several non-pharmacological interventions, particularly exercise and cognitive-behavioural therapy (CBT), have garnered good evidence of effectiveness as stand-alone, adjunctive treatments for patients with chronic pain. In this article, evidenced-based, non-pharmacological management techniques for chronic widespread pain are described by using two broad categories, exercise and CBT. The evidence for decreasing pain, improving functioning and changing secondary symptoms is highlighted. Lastly, the methods by which exercise and CBT can be combined for a multi-component approach, which is consistent with the current evidence-based guidelines of several American and European medical societies, are addressed.

    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 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.

    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.

    The devastating impacts of chronic pain include not only disability and emotional distress, but also challenges to patients’ sense of self. Patients experience self-discrepancy when they believe that they can no longer fulfill their hopes or responsibilities. While the impact of self-discrepancy on patients’ chronic pain adjustment has been widely examined, the underlying mechanism is still unclear. The present study therefore aimed to first examine the causal relationship between self-discre...

    2010-01-01

    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.

    The relationship between corticosteroids (endogenous and exogenous) and stress is well known, as is the use of steroids as concomitant treatment in pain management during acute inflammation. In the past, steroids have not been considered the first line of treatment in pain management. In this review, we examine new scientific and clinical evidence that demonstrates the direct role that steroids play in the generation and clinical management of chronic pain. We will discuss the new findings demonstrating the fact that steroids and related mediators produce paradoxical effects on pain such as analgesia, hyperalgesia, and even placebo analgesia. In addition, we will examine the physiologic effect of stress, high allostatic load, and idiopathic disease states such as chronic fatigue syndrome, fibromyalgia, irritable bowel syndrome, and burnout. The recently observed positive relationship between glutaminergic activity in the insula and clinical pain will be examined in the context of understanding the central role of steroids in chronic pain. The complex role of the hypothalamic-pituitary-adrenal axis in pain will be discussed as well as other heterogeneous forms of chronic pain that involve many components of the central nervous system. Components of the hypothalamic-pituitary-adrenal axis have paradoxical effects on certain types of pain that are dependent on dose and on site (whether peripheral or central) and mode of application. Recent studies on glia have shown that they prolong a state of neuronal hypersensitization in the dorsal root ganglia by releasing growth factors and other substances that act on the immune system. We will discuss the implication of these new findings directly linking pain to steroids, stress, and key higher brain regions in the context of future therapeutic targets.

    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.

    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.

    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.

    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.

    Neuropathic pain induced by spinal cord injury (SCI) is clinically challenging with inadequate long-term treatment options. Partial pain relief offered by pharmacologic treatment is often counterbalanced by adverse effects after prolonged use in chronic pain patients. Cell-based therapy for neuropathic pain using GABAergic neuronal progenitor cells (NPCs) has the potential to overcome untoward effects of systemic pharmacotherapy while enhancing analgesic potency due to local activation of GABAergic signaling in the spinal cord. However, multifactorial anomalies underlying chronic pain will likely require simultaneous targeting of multiple mechanisms. Here, we explore the analgesic potential of genetically modified rat embryonic GABAergic NPCs releasing a peptidergic NMDA receptor antagonist, Serine-histogranin (SHG), thus targeting both spinal hyperexcitability and reduced inhibitory processes. Recombinant NPCs were designed using either lentiviral or adeno-associated viral vectors (AAV2/8) encoding single and multimeric (6 copies of SHG) cDNA. Intraspinal injection of recombinant cells elicited enhanced analgesic effects compared with nonrecombinant NPCs in SCI-induced pain in rats. Moreover, potent and sustained antinociception was achieved, even after a 5-week postinjury delay, using recombinant multimeric NPCs. Intrathecal injection of SHG antibody attenuated analgesic effects of the recombinant grafts suggesting active participation of SHG in these antinociceptive effects. Immunoblots and immunocytochemical assays indicated ongoing recombinant peptide production and secretion in the grafted host spinal cords. These results support the potential for engineered NPCs grafted into the spinal dorsal horn to alleviate chronic neuropathic pain.

    Full Text Available Abstract Background Use of acupuncture has widely increased in patients with chronic low back pain. However, the evidence supporting its efficacy remains unclear. In this article, we report the design and the protocol of a multi-center randomized sham-controlled trial to treat chronic low back pain. Our goal is to verify the effect of acupuncture on chronic low back pain. Methods/Design This study is a multi-center randomized sham-controlled trial with 2 parallel arms. Participants included in the study met the following criteria: 1 low back pain lasting for at least the last 3 months, 2 a documented ≥ 5 points on a 10 cm visual analog scale for bothersomeness of low back pain at the time of screening and 3 between 18 and 65 years of age. Participants were blinded to the real and sham acupuncture treatments. The real acupuncture treatment group received real acupuncture 2 times a week, during a total of 12 sessions over 6 weeks. The control group received sham acupuncture during the same period. In order to assess the primary and secondary outcome measures, the participants were asked to fill out a questionnaire at the baseline and 6, 8, 12 and 24 weeks after starting the treatments. The primary outcome was measured using the visual analog scale for bothersomeness of low back pain at 8 weeks after the initiation of treatments. Discussion The result of this trial (which will be available in 2010 will demonstrate the efficacy of using acupuncture to treat chronic low back pain.

    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.

    2016-07-01

    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.

This possible variability has important implications for evaluating the validity of pain quality measures that are directly translated into different languages without cultural adaptations. The aim of this study was to evaluate the impact of language and culture on the validity of pain quality measures by comparing the words that individuals with chronic pain from Nepal use to describe their pain with those used by patients from the USA. Methods: A total of 101 individuals with chronic musculoskeletal pain in Nepal were asked to describe their pain. The rates of the different pain descriptor domains and phrases used by the Nepali sample were then compared to the published rates of descriptors used by patients from the USA. The content validity of commonly used measures for assessing pain quality was then evaluated. Results: While there was some similarity between patients from Nepal and the USA in how they describe pain, there were also important differences, especially in how pain quality was described. For example, many patients from Nepal used metaphors to describe their pain. Also, the patients from Nepal often used a category of pain descriptor – which describes a physical state – not used by patients from the USA. Only the original McGill Pain Questionnaire was found to have content validity for assessing pain quality in patients from Nepal, although other existing pain quality measures could be adapted to be content valid by adding one or two additional descriptors

  9. Neurodegenerative properties of chronic pain: cognitive decline in patients with chronic pancreatitis.

    Directory of Open Access Journals (Sweden)

    Marijtje L A Jongsma

    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.

    We examined the relationship between catastrophizing and a 3-stage model of pain processing, consisting of pain sensation intensity (stage 1), pain unpleasantness (stage 2), and suffering (stage 3). We studied 310 patients with chronic and severe osteoarthritic knee pain (68.7% female) using 4 competing structural equation models. A strong relationship was found between the suffering construct and its indicators. Of the 4 theoretically plausible models, we found a model with 3 specific pathways of pain sensation leading to the final stage of pain-related suffering. A unique contribution of this study is the integration of catastrophizing into the 3 pain stages. In this model, catastrophizing mediates the relationship between pain-related unpleasantness and suffering, as well as the relationship between sensation and suffering through unpleasantness. Psychological intervention targeting catastrophizing could provide reduction of pain-related suffering that adds to the benefits of therapies directed toward the primary sensory and immediate unpleasant dimensions of pain. These results emphasize the benefit of integrating knowledge of the psychological and neural mechanisms of pain. Catastrophizing makes a unique contribution to suffering apart from the contribution of immediate unpleasantness. The study results emphasize the benefit of integrating knowledge of the psychological and neural mechanisms of pain, and the importance of psychological intervention targeting catastrophizing to reduce pain-related suffering.

    Clinical research has consistently detected alteration in central pain processing leading to hypersensitivity. 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. Most medications acting at central level and some non-pharmacological approaches, including psychological interventions, are likely to attenuate central hypersensitivity.

    Lee, Shaun Wen Huey; Liong, Men Long; Yuen, Kah Hay; Krieger, John N

    2014-01-01

    Objective The immune system has been implicated as one mechanism underlying the benefits of acupuncture therapy. Evidence suggests that acupuncture can ameliorate symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), but the association between clinical response and the immune system has not been investigated. Design/Setting We investigated 12 CP/CPPS patients participating in a prospective randomized clinical trial comparing acupuncture versus sham acupuncture for effects on cellular immunity. Blood samples were taken before the first needling and after the last of 20 treatment sessions (week 10). Patients also completed questionnaires examining their CP/CPPS symptoms and mood status at the baseline and end of study visits. Results At the end of study 8 of 12 participants (67%) were classified as treatment responders, 4 participants each from the acupuncture and sham groups. The acupuncture group averaged a 5% increase in natural killer cell levels compared to corresponding sham (-13%; p=0.03). Similarly, patients randomized to acupuncture reported a reduction in other white blood cell parameters examined, supporting the possibility that immunity might be important in the pathophysiology of CP/CPPS. Conclusions The specific effect of acupuncture on CP/CPPS remains unclear. Further research is warranted to examine the mechanisms by which acupuncture therapy may improve clinical symptoms in patients with CP/CPPS. PMID:25453515

  15. Chronic widespread pain in the spectrum of rheumatological diseases.

    Science.gov (United States)

    Bliddal, Henning; Danneskiold-Samsøe, Bente

    2007-06-01

    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.

  17. Cognitive-behavioral treatments for chronic pain: what works for whom?

    Science.gov (United States)

    Vlaeyen, Johan W S; Morley, Stephen

    2005-01-01

    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.

  18. Attachment and Chronic Pain in Children and Adolescents

    Full Text Available Although attachment theory is not new, its theoretical implications for the pediatric chronic pain context have not been thoroughly considered, and the empirical implications and potential clinical applications are worth exploring. The attachment framework broadly focuses on interactions between a child’s developing self-regulatory systems and their caregiver’s responses. These interactions are believed to create a template for how individuals will relate to others in the future, and may help account for normative and pathological patterns of emotions and behavior throughout life. This review outlines relevant aspects of the attachment framework to the pediatric chronic pain context. The theoretical and empirical literature is reviewed regarding the potential role of attachment-based constructs such as vulnerability and maintaining factors of pediatric chronic pain. The nature and targets of attachment-based pediatric interventions are considered, with particular focus on relevance for the pediatric chronic pain context. The potential role of attachment style in the transition from acute to chronic pain is considered, with further research directions outlined.

    [Purpose] Through core strength training, patients with chronic low back pain can strengthen their deep trunk muscles. However, independent training remains challenging, despite the existence of numerous core strength training strategies. Currently, no standardized system has been established analyzing and comparing the results of core strength training and typical resistance training. Therefore, we conducted a systematic review of the results of previous studies to explore the effectiveness of various core strength training strategies for patients with chronic low back pain. [Methods] We searched for relevant studies using electronic databases. Subsequently, we evaluated their quality by analyzing the reported data. [Results] We compared four methods of evaluating core strength training: trunk balance, stabilization, segmental stabilization, and motor control exercises. According to the results of various scales and evaluation instruments, core strength training is more effective than typical resistance training for alleviating chronic low back pain. [Conclusion] All of the core strength training strategies examined in this study assist in the alleviation of chronic low back pain; however, we recommend focusing on training the deep trunk muscles to alleviate chronic low back pain.

    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 exercise-induced changes in ALLO (r = 0.89, p exercise correlated with pain threshold 30 min after exercise (r = 0.65, p exercise-induced increases in ALLO correlated with pain tolerance 30 min after exercise (r = 0.64, p exercise-induced changes in cortisol and DHEA levels were inversely correlated with pain tolerance after exercise (r = -0.69, p 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.

    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

    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.

    Hannibal, Kara E; Bishop, Mark D

    2014-12-01

    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

    2014-09-01

    Non-oncologic chronic pain is a very common symptom. It causes great impact on daily activities of people who suffer it. The incidence of this type of pain is rising due to the increase in life expectancy. The most affected population is geriatric population. Back pain, osteoarthritic pain and neuropathic pain are the most prevalent types of non-oncologic chronic pain. Opiates, among other analgesic drugs, are used to alleviate this type of pain. Opiates are divided into minor opiates (tramadol, codeine) and major opiates (morphine, fentanyl, oxycodone, methadone). Opiates are very effective to treat pain, but they also have important adverse effects that we must know and try to prevent. One of these adverse effects is the opiates ability to cause dependence, tolerance, addiction and other aberrant behaviors. Terminology of these concepts is sometimes confusing. It is necessary to be careful and control the patient periodically in order to avoid these aberrant behaviors. However, if health professionals take precautions to prevent these behaviors, the risk is considerably reduced. Controlling patients on opiate treatment is essential to achieve a correct use if these drugs.

    2014-08-01

    Patients' beliefs about the origin of their pain and their cognitive processing of pain-related information have both been shown to be associated with poorer prognosis in low back pain (LBP), but the relationship between specific beliefs and specific cognitive processes is not known. The aim of this study was to examine the relationship between diagnostic uncertainty and recall bias in 2 groups of chronic LBP patients, those who were certain about their diagnosis and those who believed that their pain was due to an undiagnosed problem. Patients (N=68) endorsed and subsequently recalled pain, illness, depression, and neutral stimuli. They also provided measures of pain, diagnostic status, mood, and disability. Both groups exhibited a recall bias for pain stimuli, but only the group with diagnostic uncertainty also displayed a recall bias for illness-related stimuli. This bias remained after controlling for depression and disability. Sensitivity analyses using grouping by diagnosis/explanation received supported these findings. Higher levels of depression and disability were found in the group with diagnostic uncertainty, but levels of pain intensity did not differ between the groups. Although the methodology does not provide information on causality, the results provide evidence for a relationship between diagnostic uncertainty and recall bias for negative health-related stimuli in chronic LBP patients.

  12. Central Hyperexcitability in Chronic Musculoskeletal Pain: A Conceptual Breakthrough with Multiple Clinical Implications

    Directory of Open Access Journals (Sweden)

    Jan Lidbeck

    2002-01-01

    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.

    Matthias Zunhammer

    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.

    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.

    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.

    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.

    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.

  18. Craniosacral Therapy for the Treatment of Chronic Neck Pain

    OpenAIRE

    2016-01-01

    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)...

    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.

    In an acute environment pain has potential protective benefits. However when pain becomes chronic this protective effect is lost and the pain becomes an encumbrance. Previously unheralded substances are being investigated in an attempt to alleviate the burden of living with chronic pain. Oxytocin, a neuropeptide hormone, is one prospective pharmacotherapeutic agent gaining popularity. Oxytocin has the potential to modulate the pain experience due to its ubiquitous involvement in central and peripheral psychological and physiological processes, and thus offers promise as a therapeutic agent. In this review, we discuss previous effective applications of oxytocin in pain-free clinical populations and its potential use in the modulation of pain experience. We also address the slowly growing body of literature investigating the administration of oxytocin in clinical and experimentally induced pain in order to investigate the potential mechanisms of its reported analgesic actions. We conclude that oxytocin offers a potential novel avenue for modulating the experience of pain, and that further research into this area is required to map its therapeutic benefit.

  3. Why harmless sensations might hurt in individuals with chronic pain: About heightened prediction and perception of pain in the mind

    2016-10-01

    Full Text Available In individuals with chronic pain harmless bodily sensations can elicit anticipatory fear of pain resulting in maladaptive responses such as taking pain medication. Here, we aim to broaden the perspective taking into account recent evidence that suggests that interoceptive perception is largely a construction of beliefs, which are based on past experience and that are kept in check by the actual state of the body. Taking a Bayesian perspective, we propose that individuals with chronic pain display a heightened prediction of pain (prior probability p(pain, which results in heightened pain perception (posterior probability p(pain|sensation due to an assumed link between pain and a harmless bodily sensation (p(sensation│pain. This pain perception emerges because their mind infers pain as the most likely cause for the sensation. When confronted with a mismatch between predicted pain and a (harmless bodily sensation, individuals with chronic pain try to minimize the mismatch most likely by active inference of pain or by an attentional shift. The active inference results in activities that produce a stronger sensation that will match with the prediction, allowing subsequent perceptual inference of pain. Here, we depict heightened pain perception in individuals with chronic pain by reformulating and extending the assumptions of the interoceptive predictive coding model from a Bayesian perspective. The review concludes with a research agenda and clinical considerations.

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.

  5. Perspectives on physiotherapy guidelines for chronic low back pain

    2007-02-01

    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

    Pain and inflammation in the absence of infection are hallmarks in chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) patients. The etiology of CP/CPPS is unclear, and autoimmunity has been proposed as a cause. Experimental autoimmune prostatitis (EAP) models have long been used for studying CP/CPPS. Herein, we studied prostate inflammation induction and chronic pelvic pain development in EAP using IL-12p40-KO, IL-4-KO, IL-17-KO, and wild-type (C57BL/6) mice. Prostate antigen (PAg) immunization in C57BL/6 mice induced specific Th1 and Th17 immune responses and severe prostate inflammation and cell infiltration, mainly composed of CD4 T cells and macrophages. Moreover, chronic pelvic pain was evidenced by increased allodynia responses. In immunized IL-17-KO mice, the presence of a prominent PAg-specific Th1 immune response caused similar prostate inflammation and chronic pelvic pain. Furthermore, markedly high PAg-specific Th1 immune responses, exacerbated prostate inflammation, and chronic pelvic pain were detected in immunized IL-4-KO mice. Conversely, immunized IL-12p40-KO mice developed PAg-specific Th2 immune responses, characterized by high IL-4 secretion and neither infiltration nor damage in the prostate. As observed in wild-type control animals, IL12p40-KO mice did not evidence tactile allodynia responses. Our results suggest that, as in patients, chronic pelvic pain is a consequence of prostate inflammation. After PAg immunization, a Th1-associated immune response develops and induces prostate inflammation and chronic pelvic pain. The absence of Th1 or Th2 cytokines, respectively, diminishes or enhances EAP susceptibility. In addition, IL-17 showed not to be essential for pathology induction and chronic pelvic pain development.

    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

    Chronic pain is an issue encountered by many health care providers in their routine clinical practice. In addition to generalized patient suffering, this condition has significant clinical, psychological, and socioeconomic impact due to its widespread occurrence. The landscape of chronic pain management has been changing rapidly with an array of treatment innovations, better understanding of established therapies, and care coordination across specialties. In this article, we have reviewed emerging new modalities as well as transformation of established therapies by interventional, pharmacologic, rehabilitative, psychological, complimentary, and interdisciplinary approaches.

    2016-01-01

    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

    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.

    Chronic pain is common and undesirable after surgery. Progression from acute to chronic pain involves altered pain processing. The authors studied relationships between presence of chronic pain versus preoperative descending pain control (diffuse noxious inhibitory controls; DNICs) and postoperative persistence and spread of skin and deep tissue hyperalgesia (change in electric/pressure pain tolerance thresholds; ePTT/pPTT) up to 6 months postoperatively. In 20 patients undergoing elective major abdominal surgery under standardized anesthesia, we determined ePTT/pPTT (close to [abdomen] and distant from [leg] incision), eDNIC/pDNIC (change in ePTT/pPTT with cold pressor pain task; only preoperatively), and a 100 mm long pain visual analogue scale (VAS) (0 mm = no pain, 100 mm = worst pain imaginable), both at rest and on movement preoperatively, and 1 day and 1, 3, and 6 months postoperatively. Patients reporting chronic pain 6 months postoperatively had more abdominal and leg skin hyperalgesia over the postoperative period. More inhibitory preoperative eDNIC was associated with less late postoperative pain, without affecting skin hyperalgesia. More inhibitory pDNIC was linked to less postoperative leg deep tissue hyperalgesia, without affecting pain VAS. This pilot study for the first time links chronic pain after surgery, poorer preoperative inhibitory pain modulation (DNIC), and greater postoperative degree, persistence, and spread of hyperalgesia. If confirmed, these results support the potential clinical utility of perioperative pain processing testing.

    Neural circuits that determine the perception and modulation of pain remain poorly understood. The prefrontal cortex (PFC) provides top-down control of sensory and affective processes. While animal and human imaging studies have shown that the PFC is involved in pain regulation, its exact role in pain states remains incompletely understood. A key output target for the PFC is the nucleus accumbens (NAc), an important component of the reward circuitry. Interestingly, recent human imaging studies suggest that the projection from the PFC to the NAc is altered in chronic pain. The function of this corticostriatal projection in pain states, however, is not known. Here we show that optogenetic activation of the PFC produces strong antinociceptive effects in a rat model (spared nerve injury model) of persistent neuropathic pain. PFC activation also reduces the affective symptoms of pain. Furthermore, we show that this pain-relieving function of the PFC is likely mediated by projections to the NAc. Thus, our results support a novel role for corticostriatal circuitry in pain regulation. PMID:25834050

    Although the use of prayer as a religious coping strategy is widespread and often claimed to have positive effects on physical disorders including pain, it has never been tested in a controlled experimental setting whether prayer has a pain relieving effect. Religious beliefs and practices are complex phenomena and the use of prayer may be mediated by general psychological factors known to be related to the pain experience, such as expectations, desire for pain relief, and anxiety. Twenty religious and twenty non-religious healthy volunteers were exposed to painful electrical stimulation during internal prayer to God, a secular contrast condition, and a pain-only control condition. Subjects rated expected pain intensity levels, desire for pain relief, and anxiety before each trial and pain intensity and pain unpleasantness immediately after on mechanical visual analogue scales. Autonomic and cardiovascular measures provided continuous non-invasive objective means for assessing the potential analgesic effects of prayer. Prayer reduced pain intensity by 34 % and pain unpleasantness by 38 % for religious participants, but not for non-religious participants. For religious participants, expectancy and desire predicted 56-64 % of the variance in pain intensity scores, but for non-religious participants, only expectancy was significantly predictive of pain intensity (65-73 %). Conversely, prayer-induced reduction in pain intensity and pain unpleasantness were not followed by autonomic and cardiovascular changes.

    Pain is a complex, multidimensional experience encompassing sensory-discriminative, cognitive, emotional and motivational dimensions. These dimensions in the orofacial region have particular expression since the face and mouth have special biological, emotional and psychological meaning to each individual. Orofacial pain is frequent. Epidemiological studies reveal a high prevalence of severe pain in syndromes such as temporomandibular disorders (TMD), burning mouth syndrome and toothaches, as well as an important role of psychosocial influences, contributing to the persistence of these syndromes. Many of the difficulties experienced by clinicians with the diagnosis and management of acute and chronic orofacial pain stem from a lack of recognition and understanding of these complex conditions, the various intricate bio-psycho-social interactions and the neurobiology behind the chronicisation of acute pain. This text strives to review the important advances and insights into the peripheral processes by which noxious stimuli activates or modulates nociceptive afferent input into the brainstem, the neural pathways in the brainstem and higher levels of the trigeminal (V) somatosensory system and the mechanisms involved in the plasticity of nociceptive transmission. We shall link this knowledge to clinical correlates and suggest a therapeutic approach in acute orofacial pain, in the attempt to avoid the development of chronic pain.

    The aim of this study was to evaluate the ability of a preliminary intravenous diagnostic test to classify chronic orofacial pain patients into different subgroups. Patients with chronic orofacial pain conditions that could not be unambiguously diagnosed. A retrospective evaluation of series of conducted pharmacodiagnostic tests, consisting of the consecutive intravenous administration of drugs. Visual analogue scale scores were retrieved from all patients, based on which they were classified into different responder groups. In total, 46 pain profiles were analysed. Of these, 16 patients (35%) could be classified into one or more pain categories, while 30 patients (65%) could not be classified into any pain category. The pain duration or medication use did not influence the classification. Based on the results of this retrospective study, it seems that classification into subgroups is possible after intravenous testing in a minority of clinically unclassifiable patients. In patients where there is a substantial need for additional diagnostic information, these results may be of value. Recommendations are made for further research, which should include validation in patients with known pain mechanisms.

    The study investigates the outcome of acupuncture for chronic neck pain in a cohort of patients referred to an NHS chronic pain clinic. One hundred and seventy two patients were selected for acupuncture over a period of 6.5 years. Treatment was given by a single acupuncturist and consisted of a course of needle acupuncture for an average of seven sessions per patient. Treatment outcome was measured by an oral rating scale of improvement at the end of treatment and at follow up six months and one year after treatment. Nineteen patients were withdrawn from treatment for various reasons, two for adverse events. One hundred and fifty three patients were evaluated, of whom 68% had a successful outcome from acupuncture, reporting an improvement in pain of at least 50%. The success rate was higher in patients with a short duration of pain: 85% in patients with pain for up to three months and 78% with pain for up to six months. Long-term follow up showed that 49% of the patients who completed treatment had maintained the benefit after six months, and 40% at one year. The results indicate that acupuncture can be an effective treatment for selected patients with chronic neck pain.

    Full Text Available Background. We need to understand more about how DNF performs in different contexts and whether it affects the pain threshold over myofascial trigger points (MTrPs. Purpose. The objectives were to investigate the effect of neck muscles training on disability and pain and on pain threshold over MTrPs in people with chronic neck pain. Methods. Patients with chronic neck pain were eligible for participation with a Neck Disability Index (NDI score of over 5/50 and having at least one MTrP on either levator scapulae, upper trapezoid, or splenius capitis muscle. Patients were randomly assigned into either DNF training, superficial neck muscle exercise, or advice group. Generalized linear model (GLM was used to detect differences in treatment groups over time. Results. Out of 67 participants, 60 (47 females, mean age: 39.45 ± 12.67 completed the study. Neck disability and neck pain were improved over time between and within groups (p<0.05. However, no differences were found within and between the therapeutic groups (p<0.05 in the tested muscles’ PPTs and in cervicothoracic angle over a 7-week period. Conclusion. All three groups improved over time. This infers that the pain pathways involved in the neck pain relief are not those involved in pain threshold.

Chronic Low Back Pain (CLBP presents withenormous consequence on the general performance of the sufferer, exerting ahuge cost on the individual, the family and the society. Dance therapy is arelatively new approach in the management of low back pain. This study wastherefore designed to investigate the effect of dance therapy on pain, functionaldisability and quality of life in patients with chronic low back pain.Thirty subjects diagnosed with non-specific CLBP particpated in the study.They were randomly divided into 2 groups, A and B, each comprising 15 subjects.In addition to conventional physiotherapy programme given to both groups,subjects in Group A also received aerobic dance, which comprised a four stage protocol. The entire treatment routinewas administered in a group session three times weekly consecutively for six weeks. Data as obtained in the copies ofcompleted questionnaires (Roland Morris Diability questionnaires and Nottingham Health Profile questionnaires andother measurements were summarized using mean, standard deviation and frequency tables. Student T-test was used toanalyze the data at 95 % confidence interval.There was a statistically significant difference (p<0.05 between the pre- and post- intervention scores for painintensity, functional disability and quality of life within the groups. There was also a statistically significant difference(p<0.05 in the mean change (pre/post intervention scores between Group A and Group B for pain intensity,functional disability and quality of life. Also the opinions and testimonies given by participants formed part of theevidence-based data.Whereas both conventional physiotherapy and aerobic dance showed significant effects in the pre/post-interventionscores, the aerobic dance group reported more significant effect in all

    2004-01-01

    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.

    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.

    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 Chronic pain is a major health problem and behavioral based treatments have been shown to be effective. However, the availability of these kinds of treatments is scarce and internet-based treatments have been shown to be promising in this area. The objective of the present systematic review is to evaluate internet-based interventions for persons with chronic pain. The specific aims are to do an updated review with a broad inclusion of different chronic pain diagnoses and to assess disability and pain and also measures of catastrophizing, depression and anxiety. A systematic search identified 891 studies and 22 trials were selected as eligible for review. Two of the selected trials included children/youth and five included individuals with chronic headache and/or migraine. The most frequently measured domain reflected in the primary outcomes was interference/disability, followed by catastrophizing. Result across the studies showed a number of beneficial effects. Twelve trials reported significant effects on disability/interference outcomes and pain intensity. Positive effects were also found on psychological variable such as catastrophizing, depression and anxiety. Several studies (n = 12 were assessed to have an unclear level of risk bias. The attrition levels ranged from 4% to 54% where the headache trials had the highest drop-out levels. However, findings suggest that internet-based treatments based on cognitive behavioural therapy (CBT are efficacious measured with different outcome variables. Results are in line with trials in clinical settings. Meta-analytic statistics were calculated for interference/disability, pain intensity, catastrophizing and mood ratings. Results showed that the effect size for interference/disability was Hedge's g = −0.39, for pain intensity Hedge's g = −0.33, for catastrophizing Hedge's g = −0.49 and for mood variables (depression Hedge's g = −0.26.

    Lima, Mônica Angelim Gomes de; Trad, Leny A Bomfim

    2007-11-01

    This study aimed to shed light on the meanings ascribed to chronic pain in medical discourse and clinical practice in two Pain Clinics located in University hospitals in Salvador (Bahia) and São Paulo, Brazil. An ethnographic approach used participant observation and semi-structuralized interviews with attending and managing physicians. Data analysis drew on the clinical models developed by Byron Good and the medical rationalities project formulated by Madel Luz. The meanings emerging from the study were the recognition of chronic pain by biomedicine as a disease rather than a symptom, its invisibility to physicians, and its non-communicability and inevitability. The informants suggested the need for valorization of the human encounter in the clinic, exercise of understanding as opposed to suspicion, and negotiation of sustainable therapeutic projects.

    This study examined whether subjects with chronic low back pain demonstrate exercise-induced analgesia to experimentally induced pressure pain. We employed a repeated measures design to study eight subjects with chronic low back pain (mean +/- standard deviation age = 40 +/- 10, duration of pain = 7 +/- 4 years). Pain ratings were measured immediately before and 2 minutes and 32 minutes after 25 minutes of cycle ergometry (5 minutes at 50% peak oxygen uptake, then 20 minutes at 70% peak oxygen uptake). We based the pain ratings on subject input on a visual analog scale at 10-second intervals during the 2-minute pressure pain stimulus to the nondominant index finger. Compared with preexercise values, pain ratings were significantly (p exercise at both 2 and 32 minutes postexercise. We conclude that pressure pain perception can be reduced for more than 30 minutes following aerobic exercise from leg cycling among people with chronic low back pain.

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.

    Full Text Available 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.

    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.

    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

    This study sought to determine whether mothers of young people with chronic abdominal pain (CAP) compared to mothers of pain-free children show a pain recognition bias when they classify facial emotional expressions. One hundred demographically matched mothers of children with CAP (n=50) and control mothers (n=50) were asked to identify different emotions expressed by adults in 2 experiments. In experiment 1, participants were required to identify the emotion in a series of facial images that depicted 100% intensity of the following emotions: Pain, Sadness, Anger, Fear, Happiness, and Neutral. In experiment 2, mothers were required to identify the predominant emotion in a series of computer-interpolated ("morphed") facial images. In this experiment, pain was combined with Sad, Angry, Fearful, Happy, and Neutral facial expressions in different proportions-that is, 90%:10%, 70%:30%, 50%:50%, 30%:70%, 10%:90%. All participants completed measures of state and trait anxiety, depression, and anxiety sensitivity. In experiment 1, there was no difference in the performance of the 2 groups of mothers. In experiment 2, it was found that overall mothers of children with CAP were classifying ambiguous emotional expressions predominantly as pain. Mean response times for CAP and control groups did not differ significantly. Mothers of children with CAP did not report more anxiety, depression, and anxiety sensitivity compared to control mothers. It is concluded that mothers of children with CAP show a pain bias when interpreting ambiguous emotional expressions, which possibly contributes to the maintenance of this condition in children via specific parenting behaviours.

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.

    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.

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.

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.

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.

    Full Text Available This study examined intra- and inter-personal associations between pain catastrophizing and verbal expression in 70 children with recurrent abdominal pain and their mothers. Participants independently completed the Pain Catastrophizing Scale. Mothers and children then talked about the child’s pain. Speech was categorized using a linguistic analysis program. Catastrophizing was positively associated with the use of negative emotion words by both mothers and children. In addition, mothers’ catastrophizing was positively associated with both mothers’ and children’s anger word usage, whereas children’s catastrophizing was inversely associated with mothers’ anger word usage. Findings extend the literature on behavioral and interpersonal aspects of catastrophizing.

    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.

    Evaluation of abdominal pain requires an understanding of the possible causes(benign or malignant) and recognition of typical patterns and clinical presentation. Abdominal pain has multiple causes; associated signs and symptoms may aid in the diagnosis. Remember that some patients will not have a textbook presentation, and unusual causes for pain must be considered. Those with chronic pancreatitis with structural complications should be operated on early, whereas those with other types of chronic pancreatitis should receive medical therapy focusing on alleviating symptoms. Control of the most troublesome symptoms will provide the best management for IBS. Pharmacologic success in bowel obstruction depends on the level and degree of obstruction. Decision making is based on reasonable expectations of survival, treatment-related success, performance status, and goals of care. Quality of life will be enhanced by appropriate symptom management.

    Several theories about musculoskeletal pain syndromes such as whiplash-associated disorder (WAD) suggest that pain and muscle activity interact and may contribute to the chronicity of symptoms. Studies using surface electromyography (sEMG) have demonstrated abnormal muscle activation patterns of the upper trapezius muscles in the chronic stage of WAD (grade II). There are, however, no studies that confirm that these muscle reactions are initiated in the acute stage of WAD, nor that these muscle reactions persist in the transition from acute neck pain to chronic neck pain disability. We analyzed the muscle activation patterns of the upper trapezius muscles in a cohort of 92 subjects with acute neck pain due to a motor vehicle accident (MVA). This cohort was followed up in order to evaluate differences in muscular activation patterns between subjects who have recovered and those subjects who have not recovered following an acute WAD and developed chronic neck pain. sEMG parameters were obtained at 1, 4, 8, 12, and 24 weeks after an MVA. The level of muscle reactivity (the difference in pre- and post-exercise EMG levels) and the level of muscle activity during an isometric and a dynamic task were used as EMG parameters. The results revealed no elevated muscle reactivity either in the acute stage, or during the follow-up period. The results of both the isometric and dynamic task, showed statistically significant different EMG levels between four neck pain disability subgroups (analysis of variance reaching P-levels of 0.000), with an inverse relationship between the level of neck pain disability and EMG level. Furthermore, follow-up assessments of the EMG level during these two tasks, did not show a time related change. In conclusion, in subjects with future disability, the acute stage is characterized by a reorganization of the muscular activation of neck and shoulder muscles, possibly aimed at minimizing the use of painful muscles. This change of motor control, is in

  15. Chronic proctalgia and chronic pelvic pain syndromes: New etiologic insights and treatment options

    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.

  16. Effective physical treatment for chronic low back pain.

    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.

    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.

    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.

    Chronic pelvic pain is a frustrating symptom for patients with endometriosis and is frequently refractory to hormonal and surgical management. While these therapies target ectopic endometrial lesions, they do not directly address pain due to central sensitization of the nervous system and myofascial dysfunction, which can continue to generate pain from myofascial trigger points even after traditional treatments are optimized. This article provides a background for understanding how endometriosis facilitates remodeling of neural networks, contributing to sensitization and generation of myofascial trigger points. A framework for evaluating such sensitization and myofascial trigger points in a clinical setting is presented. Treatments that specifically address myofascial pain secondary to spontaneously painful myofascial trigger points and their putative mechanisms of action are also reviewed, including physical therapy, dry needling, anesthetic injections, and botulinum toxin injections.

    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

    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.

    Osteoarthritis is a prevalent disease in older patients of all racial groups, and it is known to cause significant pain and functional disability. Racial differences in how patients cope with the chronic pain of knee or hip osteoarthritis may have implications for utilization of treatment modalities such as joint replacement. Therefore, we examined the relationships between patient race and pain coping strategies (diverting attention, reinterpreting pain, catastrophizing, ignoring sensations, hoping and praying, coping self-statements, and increasing behavior activities) for hip and knee osteoarthritis. This is a cross-sectional survey of 939 veterans 50 to 79 years old with chronic hip or knee osteoarthritis pain recruited from VA primary care clinics in Philadelphia and Pittsburgh. Patients had to have moderate to severe hip or knee osteoarthritis symptoms as measured by the WOMAC index. Standard, validated instruments were used to obtain information on attitudes and use of prayer, pain coping strategies, and arthritis self-efficacy. Analysis included separate multivariable models adjusting for demographic and clinical characteristics. Attitudes on prayer differed, with African Americans being more likely to perceive prayer as helpful (adjusted OR = 3.38, 95% CI 2.35 to 4.86) and to have tried prayer (adjusted OR = 2.28, 95% 1.66 to 3.13) to manage their osteoarthritis pain. Upon evaluating the coping strategies, we found that, compared to whites, African Americans had greater use of the hoping and praying method (beta = 0.74, 95% CI 0.50 to 0.99). Race was not associated with arthritis pain self-efficacy, arthritis function self-efficacy, or any other coping strategies. This increased use of the hoping and praying coping strategy by African Americans may play a role in the decreased utilization of total joint arthroplasty among African Americans compared to whites. Further investigation of the role this coping strategy has on the decision making process for

    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.

  13. Alexithymia is associated with greater risk of chronic pain and negative affect and with lower life satisfaction in a general population: the Hisayama Study.

    Mao Shibata

    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

    The interaction of nurses with chronic pain patients is often difficult. One of the reasons is that chronic pain is difficult to explain, because no obvious anatomic defect or tissue damage is present. There is now enough evidence available indicating that chronic pain syndromes such as low back pai

    The antinociceptive effect of alpha(2)-adrenoceptor agonists is mediated by activation of descending inhibiting noradrenergic systems, which modulates 'wide-dynamic-range' neurones. Furthermore, they inhibit the liberation of substance P and endorphines and activate serotoninergic neurones. Despite this variety of antinociceptive actions, there is still little experience with alpha(2)-adrenoceptor agonists as therapeutic agents for use in chronic pain syndromes. Studies in animals and patients have shown that the transdermal, epidural and intravenous administration of the alpha(2)-adrenoceptor agonist clonidine reduces pain intensity in neuropathic pain syndromes for periods varying from some hours up to 1 month. Patients suffering from lancinating or sharp pain respond best to this therapy. Topically applied clonidine (200-300 microg) relieves hyperalgesia in sympathetically maintained pain. Epidural administration of 300 microg clonidine dissolved in 5 ml NaCl 0.9 % has also been shown to be effective. In patients suffering from cancer pain tolerant to opioids, pain control has proved possible again with combinations of opioids and clonidine. In isolated cases clonidine has been administered epidurally at a dose of 1500 microg/day for almost 5 months without evidence for any histotoxic property of clonidine. Side effects often observed during administration of alpha(2)-adrenoceptor agonists are dry mouth, sedation, hypotension and bradycardia. Therapeutic interventions are usually not required.

    The diagnosis and management of chronic anterior knee pain in the active individual can be frustrating for both the patient and physician. Pain may be a result of a single traumatic event or, more commonly, repetitive overuse. "Anterior knee pain," "patellofemoral pain syndrome," and "chondromalacia" are terms that are often used interchangeably to describe multiple conditions that occur in the same anatomic region but that can have significantly different etiologies. Potential pain sources include connective or soft tissue irritation, intra-articular cartilage damage, mechanical irritation, nerve-mediated abnormalities, systemic conditions, or psychosocial issues. Patients with anterior knee pain often report pain during weightbearing activities that involve significant knee flexion, such as squatting, running, jumping, and walking up stairs. A detailed history and thorough physical examination can improve the differential diagnosis. Plain radiographs (anteroposterior, anteroposterior flexion, lateral, and axial views) can be ordered in severe or recalcitrant cases. Treatment is typically nonoperative and includes activity modification, nonsteroidal anti-inflammatory drugs, supervised physical therapy, orthotics, and footwear adjustment. Patients should be informed that it may take several months for symptoms to resolve. It is important for patients to be aware of and avoid aggravating activities that can cause symptom recurrence. Patients who are unresponsive to conservative treatment, or those who have an underlying systemic condition, should be referred to an orthopedic surgeon or an appropriate medical specialist.

    There are still many things to be found out about interstitial cystitis/painful bladder syndrome (IC/PBS) because the pathological processes underlying the condition are not yet elucidated, biological markers of the condition are not yet available, and the type and severity of symptoms can vary, so, clearly defining the condition is not yet possible. For example, it is not clearly understood whether IC/PBS represents a systemic disease, if it is localized in the bladder, or if it was initially localized in the bladder and it later evolved into a systemic disease. This condition is best managed by using a multidisciplinary approach. Management requires a good integration and knowledge of all pelvic organ systems and other systems including musculoskeletal, neurologic, and psychiatric systems.

    Full Text Available Abstract Background The use of opioid medications as treatment for chronic non-cancer pain remains controversial. Little information is currently available regarding healthcare providers' attitudes and beliefs about this practice among older adults. This study aimed to describe primary care providers' experiences and attitudes towards, as well as perceived barriers and facilitators to prescribing opioids as a treatment for chronic pain among older adults. Methods Six focus groups were conducted with a total of 23 physicians and three nurse practitioners from two academically affiliated primary care practices and three community health centers located in New York City. Focus groups were audiotape recorded and transcribed. The data were analyzed using directed content analysis; NVivo software was used to assist in the quantification of identified themes. Results Most participants (96% employed opioids as therapy for some of their older patients with chronic pain, although not as first-line therapy. Providers cited multiple barriers, including fear of causing harm, the subjectivity of pain, lack of education, problems converting between opioids, and stigma. New barriers included patient/family member reluctance to try an opioid and concerns about opioid abuse by family members/caregivers. Studies confirming treatment benefit, validated tools for assessing risk and/or dosing for comorbidities, improved conversion methods, patient education, and peer support could facilitate opioid prescribing. Participants voiced greater comfort using opioids in the setting of delivering palliative or hospice care versus care of patients with chronic pain, and expressed substantial frustration managing chronic pain. Conclusions Providers perceive multiple barriers to prescribing opioids to older adults with chronic pain, and use these medications cautiously. Establishing the long-term safety and efficacy of these medications, generating improved prescribing methods

    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.

    2012-09-01

    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

    Throughout the Western world people turn towards the health care system seeking help for a variety of psychosomatic/psychosocial health problems. They become "patients" and find themselves within a system of practises that conceptualizes their bodies as "objective" bodies, treats their ill health in terms of the malfunctioning machine, and compartmentalizes their lived experiences into medically interpreted symptoms and signs of underlying biological dysfunction. The aim of this article is to present an alternative way of describing ill health and rehabilitation using the philosophy of Maurice Merleau-Ponty in order to deepen our understanding of the rehabilitation process. I will explore how the experience of chronic pain ruptures the natural connection between body and world and how the rehabilitation process can be understood as the re-insertion of the body into the flow of experience, where the body "disappears" into its natural silence in order to allow the world to once again unfold. The experience of chronic pain places the painful body in focus, resulting in a diminished articulation of both self and world. Persons with illness suffer not only from the physical aspects of pain and discomfort but also from a loss of identity where one feels alienated and detached from things that used to give meaning to ones life. Rehabilitation must not only address the material (medical) body but also the diminished sense of self as well as the retreat from the world outside of the painful body.

Methods A total of 32 patients received alternative opioid therapy, 16 were switched from buprenorphine to fentanyl and 16 were switched from fentanyl to buprenorphine. The dosage used was 50% of that indicated in equipotency conversion tables. Pain relief was assessed at weekly intervals for the next 3 weeks Results Pain relief as assessed by VAS, PPI, and PRI significantly improved (p Conclusion Opioid switching at 50% of the calculated equianalgesic dose produced a significant reduction in pain levels and rescue medication. The incidence of side effects decreased and no new side effects were noted.

    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

    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.

    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.

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

    Full Text Available 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 motor cortex stimulation 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 motor cortex stimulation 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.

    A semiotic conceptualization of pain in the chronic pain syndrome is proposed. It is suggested that among chronic pain patients pain ceases to be an icon or an index and acquires a symbolic structure: this transformation interferes with the usual patient-physician relationship. The semiotic perspective on the structure of meaning in the chronic pain syndrome underlines the need to include a psychotherapeutic approach in the patient-physician relationship; specific aspects of the approach to chronic pain as a symbolic communication are discussed.

    Several studies have reported lower neck muscle strength in patients with chronic neck pain compared to healthy controls. The aim of the present study was to evaluate the association between the severity of neck pain and disability with neck strength and range of movement in women suffering from chronic neck pain. One hundred and seventy-nine female office workers with chronic neck pain were selected to the study. The outcome was assessed by the self-rating questionnaires on neck pain (visual analogue scale, Vernon's disability index, Neck pain and disability index) and by measures of the passive range of movement (ROM) and maximal isometric neck muscle strength. No statistically significant correlation was found between perceived neck pain and the disability indices and the maximal isometric neck strength and ROM measures. However, the pain values reported during the strength tests were inversely correlated with the results of strength tests (r=-0.24 to -0.46), showing that pain was associated with decreased force production. About two-thirds of the patients felt pain during test efforts. Pain may prevent full effort during strength tests and hence the production of maximal force. Thus in patients with chronic neck pain the results do not always describe true maximal strength, but rather the patients' ability to bear strain, which may be considerably influenced by their painful condition. The results of the present study suggest that rehabilitation in cases of chronic neck pain should aim at raising tolerance to mechanical strain.

    Reduced cervical range of motion (ROM) is a common finding in people with neck pain. With few exceptions, only the angle between head and thorax has been measured. Our aim was to use an extended model to compare active cervical flexion and extension, separate for upper and lower cervical levels, between people with chronic non-traumatic neck pain and controls. We also investigated associations between ROM measures, symptoms and self-rated functioning. In this cross-sectional study, 102 subjects with neck pain and 33 healthy controls participated. An electromagnetic tracker system was used to measure the kinematics to construct a three-segment model including the thorax, cervical spine and head. Neutral flexion/extension were defined at subjects' self-selected seated posture. We found that in the neck pain group, extension in the upper cervical levels and predominately flexion for the lower levels were reduced. The ratio between ROM for the upper and lower levels was altered in the neck pain group so that the lower levels contributed to a lesser extent to the total sagittal ROM compared to controls. These findings could not be explained by a greater forward head posture but must have other origins. For the neck pain group, ROM measures were weakly associated to pain and self-rated functioning. Altogether, this implies that using a three-segment model for assessment of ROM can be a valuable improvement for characterisation of patients and treatment evaluation.

    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.

    The neurobiology of chronic pain, including chronic daily headache (CDH) is not completely understood. “Pain memory” hypothesis is one of the mechanisms for phantom limb pain. We reviewed the literature to delineate a relation of “pain memory” for the development of CDH. There is a direct relation of pain to memory. Patients with poor memory have less chance to develop “pain memory”, hence less possibility to develop chronic pain. Progressive memory impairment may lead to decline in headache ...

    Full Text Available Pain is defined by the International Association for the Study of Pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Pain has now been equated to a fifth vital sign highlighting the significance of pain management in patient care. Tramadol is a centrally acting analgesic which is structurally related to codeine and morphine. It is effectively used to treat moderate to severe acute and chronic pain in diverse conditions. Tramadol is placed on the second step of WHO analgesic ladder and in contrast to traditional opioids, exerts its analgesic activity, a dual mechanism of action inhibiting transmission as well as perception of pain. Tramadol is more suitable than NSAID’s and coxib’s for patient with GI, renal and cardiovascular problems. Combined with low dependence/abuse potential, it has proven to be of significant advantage over other agents especially in the elderly.

    Plantar incision in rat generates spontaneous pain behaviour. The opioid drug, morphine used to treat postsurgical pain produces tolerance after long-term administration. Loperamide, a potent mu-opioid agonist, has documented analgesic action in various pain conditions. However, loperamide analgesia and associated tolerance following continuous spinal administration in postsurgical pain has not been reported. Chronic spinal infusion of drugs was achieved using intrathecal catheters connected to osmotic minipump. Coinciding with the onset of spinal infusion of loperamide or morphine, rats were subjected to plantar incision. Pain-related behaviour was assessed by Hargreaves apparatus (thermal hyperalgesia) and von Frey filaments (mechanical allodynia). Morphine and loperamide (0.5, 1 and 2 microL/h) induced analgesia was observed until 7th day post-plantar incision in Sprague-Dawley rats. Morphine and loperamide produced dose-dependent analgesia. Loperamide, in the highest dose, produced analgesia till 7th day. However, the highest dose of morphine produced inhibition of thermal hyperalgesia till 5th day and mechanical allodynia only till 3rd day post-plantar incision. Morphine and loperamide produced analgesia in postsurgical pain, which may be mediated through different mechanisms. Longer duration of analgesia with loperamide could probably be due sustained blockade of calcium channels.

    Acupuncture is a promising therapy for relieving symptoms in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which affects >15% of adult men worldwide. The aim of the study was to assess the effects and safety of the use of acupuncture for CP/CPPS. MEDLINE, EMBASE, CENTRAL, Web of Science, CBM, CNKI, Wang-Fang Database, JCRM, and CiNii were searched from their inception through 30 November 2015. Grey literature databases and websites were also searched. No language limits were applied. Only randomized controlled trials (RCTs) with CP/CPPS treated by acupuncture were included. Two reviewers extracted data and assessed the risk of bias of RCTs using the Cochrane Risk of Bias Tools, respectively. Seven trials were included, involving 471 participants. The result of meta-analysis indicated that compared with sham acupuncture (MD: -6.09 [95%CI: -8.12 to -5.68]) and medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) (MD: -4.57 [95%CI: -7.58 to -1.56]), acupuncture was more effective at decreasing the total NIH-CPSI score. Real acupuncture was superior to sham acupuncture in improving symptoms (pain, voiding) and quality of life (Qof) domain subscores. Compared to sham acupuncture and medicine, acupuncture appears to be more effective at improving the global assessment. Two trials found that there is no significant difference between acupuncture and sham acupuncture in decreasing the IPSS score. Acupuncture failed to show more favorable effects in improving both symptoms and the Qof domain compared with medicine. Overall, current evidence supports acupuncture as an effective treatment for CP/CPPS-induced symptoms, particularly in relieving pain. Based on the meta-analysis, acupuncture is superior to sham acupuncture in improving symptoms and Qof. Acupuncture might be similar to medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) in its long-term effects, but evidence was limited due to high ROB among included trials as well as potential heterogeneity

    Cognitive behavioral therapy, such as environmental enrichment combined with voluntary exercise (EE-VEx), is under active investigation as an adjunct to pharmaceutical treatment for chronic pain. However, the effectiveness and underlying mechanisms of EE-VEx remain unclear. In mice with intra-plantar injection of complete Freund's adjuvant (CFA), our results revealed that EE-VEx alleviated perceptual, affective and cognitive dimensions of chronic inflammatory pain. These effects of EE-VEx on chronic pain were contingent on the occurrence of adult neurogenesis in the dentate gyrus in a functionally dissociated manner along the dorsoventral axis: neurogenesis in the ventral dentate gyrus participated in alleviating perceptual and affective components of chronic pain by EE-VEx, whereas neurogenesis in the dorsal dentate gyrus was involved in EE-VEx's cognitive-enhancing effects. Chronic inflammatory pain was accompanied by decreased levels of brain-derived neurotrophic factor (BDNF) in the dentate gyrus, which were reversed by EE-VEx. Over-expression of BDNF in the dentate mimicked the effects of EE-VEx. Our results demonstrate distinct contribution of adult hippocampal neurogenesis along the dorsoventral axis to EE-VEx's beneficial effects on different dimensions of chronic pain.SIGNIFICANCE STATEMENTEnvironmental enrichment combined with voluntary exercise (EE-VEx) is under active investigation as an adjunct to pharmaceutical treatment for chronic pain, but its effectiveness and underlying mechanisms remain unclear. In a mouse model of inflammatory pain, the present study demonstrates that the beneficial effects of EE-VEx on chronic pain depend on adult neurogenesis with a dorsoventral dissociation along the hippocampal axis. Adult neurogenesis in the ventral dentate gyrus participates in alleviating perceptual and affective components of chronic pain by EE-VEx, whereas that in the dorsal pole is involved in EE-VEx's cognitive-enhancing effects in chronic pain.

    Full Text Available Abstract Background Chronic pain patients are common in general practice. In this study "chronic pain" is defined as diffuse musculoskeletal pain not due to inflammatory diseases or cancer. Effective patient-physician relations improve treatment results. The relationship between doctors and chronic pain patients is often dysfunctional. Consultation training for physicians and medical students can improve the professional ability to build effective relations, but this demands a thorough understanding of the problems in the relation. Several studies have defined the issues that frequently cause problems, but few have described the process. The aim of this study was to understand and illustrate what GPs' experience in contact with chronic pain patients and what works and does not work in these consultations. Methods Our theoretical perspective is constructivist, based upon the relativist view that individuals construct realities to understand and navigate the world. Five Swedish General Practitioners (GPs, two male and three female, were interviewed and asked to tell a story about a difficult encounter with a chronic pain patient. Tapes of the interviews were transcribed and analysed using narrative analysis. Three GPs told narratives suited for our analytic tools and these were included in the final results. Results Each narrative highlights a certain dilemma and a strategy. The dilemmas were: power game; good intentions that fail when a patient is persuaded against her own conviction; persuasion of the unwilling; transferred tiredness; distrust and dissociation from the patient. Professional strategies of listening, encouraging and teamwork were central to handling difficult situations. Conclusions The narratives show that GP's consultations with chronic pain patients sometimes are characterized by conflicts and difficult situations. They are facilitated by methods such as active listening and teamwork, but still may remain hard to handle. This

    Abstract This cross-sectional study investigates the plasma inflammatory profile of chronic widespread pain (CWP) patients compared to healthy controls (CON). Rather than analyzing a relatively few substances at a time, we used a new multiplex proximity extension assay (PEA) panel that enabled the simultaneous analysis of 92 inflammation-related proteins, mainly cytokines and chemokines. Seventeen women with CWP and 21 female CON participated and a venous blood sample was drawn from all subjects. Pain intensity and pain thresholds for pressure, heat, and cold were registered. A PEA panel (92 proteins) was used to analyze the blood samples. Multivariate data analysis by projection was used in the statistical analyses. Eleven proteins significantly differentiated the CON and CWP subjects (R2 = 0.58, Q2 = 0.37, analysis of variance of cross-validated predictive residuals P = 0.006). It was not possible to significantly regress pain thresholds within each group (CON or CWP). Positive significant correlations existed between several proteins and pain intensities in CWP, but the model reliability of the regression was poor. CWP was associated with systemic low-grade inflammation. Larger studies are needed to confirm the results and to investigate which alterations are condition-specific and which are common across chronic pain conditions. The presence of inflammation could promote the spreading of pain, a hallmark sign of CWP. As it has been suggested that prevalent comorbidities to pain (e.g., depression and anxiety, poor sleep, and tiredness) also are associated with inflammation, it will be important to determine whether inflammation may be a common mediator.

    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
