Chronic pelvic pain is pain lasting longer than 6 months and is estimated to occur in 15% of women. Causes of pelvic pain include disorders of gynecologic, urologic, gastroenterologic, and musculoskeletal systems. The multidisciplinary nature of chronic pelvic pain may complicate diagnosis and treatment. Treatments vary by cause but may include medicinal, neuroablative, and surgical treatments.

Full Text Available Background. Chronic unexplained orofacial pain is frequently the cause of prolonged suffering for the patient and an unsolvable problem for the therapist. Pathophysiology of the onset of this type of pain is virtually unknown. Still, it is possible to divide chronic orofacial pain into several separate categories, according to its onset, symptoms and therapy. All forms of this type of pain have a strong psychological component.Methods. A retrograde review was conducted, in which patients’ records, treated in 1994 for chronic unexplained orofacial pain, were followed through a 5 year period. The modalities of treatment then and at present were compared.Conclusions. Except for trigeminal neuralgia, where carbamazepine remains the first choice drug, treatment of chronic facial pain has changed considerably.

Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.
Chronic, unexplained pain (CUP) is a common clinical problem. The core symptom in this heterogeneous group of patients is pain for which no medical explanation is found. Patients also have many other characteristics (symptoms and psychosocial features) in common. Pathophysiologically, increased

Although most patients recover from acute whiplash injuries, those with chronic whiplash syndrome develop signs of central nervous system (CNS) amplification of pain and have a poor prognosis. In this context, specific pain generators from acute whiplash have been identified through clinical, biomechanical, and animal studies. This article gives a clinical perspective on current understanding of these pain generators, including the phenomenon of CNS sensitization. Copyright © 2015 Elsevier Inc. All rights reserved.
Full Text Available Chronic pelvic pain (CPP is defined as nonmalignant pain perceived in the structures related to the pelvis that has been present for more than 6 months or a non acute pain mechanism of shorter duration. Pain in the pelvic region can arise from musculoskeletal, gynaecological, urologic, gastrointestinal and or neurologic conditions. Key gynaecological conditions that contribute to CPP include pelvic inflammatory disease (PID, endometriosis, adnexa pathologies (ovarian cysts, ovarian remnant syndrome, uterine pathologies (leiomyoma, adenomyosis and pelvic girdle pain associated with pregnancy. Several major and minor sexually transmitted diseases (STD can cause pelvic and vulvar pain. A common painful condition of the urinary system is Interstitial cystitis(IC. A second urologic condition that can lead to development of CPP is urethral syndrome. Irritable bowel syndrome (IBS is associated with dysmenorrhoea in 60% of cases. Other bowel conditions contributing to pelvic pain include diverticular disease,Crohn′s disease ulcerative colitis and chronic appendicitis. Musculoskeletal pathologies that can cause pelvic pain include sacroiliac joint (SIJ dysfunction, symphysis pubis and sacro-coccygeal joint dysfunction, coccyx injury or malposition and neuropathic structures in the lower thoracic, lumbar and sacral plexus. Prolonged pelvic girdle pain, lasting more than 6 months postpartum is estimated in 3% to 30% of women. Nerve irritation or entrapment as a cause of pelvic pain can be related to injury of the upper lumbar segments giving rise to irritation of the sensory nerves to the ventral trunk or from direct trauma from abdominal incisions or retractors used during abdominal surgical procedures. Afflictions of the iliohypogastric, ilioinguinal, genitofemoral, pudendal and obturator nerves are of greatest concern in patients with pelvic pain. Patient education about the disease and treatment involved is paramount. A knowledge of the differential

Chronic Pain extracts a "penalty" on society now estimated to be well in excess of $100 million per year. The "penalty" that Chronic Pain extracts from its victims is incalculable. Chronic Pain is a major component of Temporomandibular Disorders. The current neurological theory of the mechanism of chronic TMD pain is explored along with the current modes of treatment. Pharmacological management of Chronic Pain in a clinical setting is outlined. Dentists are involved in pain management on a daily basis. Dentists treat pain both prophylacticly and in response to specific patient symptoms. Most dental treatment involves some type of pain management. We, dentists, have become very adept at managing acute pain. We have much greater difficulty managing chronic pain. The word "pain" derives from the Greek word for penalty, and appeared to them to be a "penalty" inflicted by the gods. In 1984, Bonica estimated that one-third of all Americans suffered from some kind of chronic pain at a "penalty" to society of $65 Billion annually in medical expenses and lost wages and productivity. This figure is certainly much greater now. Chronic pain can be a very complex problem that can require a multidisciplinary approach to treatment. Chronic pain in the dental setting is most frequetly caused by prolonged Temporomandibular Disorders.

The purpose of this study was to provide the most up-to-date scientific evidence of the potential analgesic effects, or lack thereof, of the marijuana plant (cannabis) or cannabinoids, and of safety or tolerability of their long-term use. We found that inhaled (smoked or vaporized) cannabis is consistently effective in reducing chronic non-cancer pain. Oral cannabinoids seem to improve some aspects of chronic pain (sleep and general quality of life), or cancer chronic pain, but they do not seem effective in acute postoperative pain, abdominal chronic pain, or rheumatoid pain. The available literature shows that inhaled cannabis seems to be more tolerable and predictable than oral cannabinoids. Cannabis or cannabinoids are not universally effective for pain. Continued research on cannabis constituents and improving bioavailability for oral cannabinoids is needed. Other aspects of pain management in patients using cannabis require further open discussion: concomitant opioid use, medical vs. recreational cannabis, abuse potential, etc.
This review includes a summary of contemporary theories of pain processing and advocates a multimodal analgesia approach for providing perioperative care. A summary of various medication classes and anesthetic techniques is provided that highlights evidence emerging from neurosurgical literature. This summary covers opioid management, acetaminophen, nonsteroidal antiinflammatories, ketamine, lidocaine, dexmedetomidine, corticosteroids, gabapentin, and regional anesthesia for neurosurgery. At present, there is not enough investigation into these areas to describe best practices for treating or preventing chronic pain in neurosurgery; but providers can identify a wider range of options available to personalize perioperative care strategies.

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 web-based delivery of psychosocial interventions is a promising treatment modality for people suffering from chronic pain, and other forms of physical and mental illness. Despite the promising findings of first studies, patients may vary in the benefits they draw from self-managing a full-blown web-based psychosocial treatment. We lack knowledge on moderators and predictors of change during web-based interventions that explain for whom web-based interventions are especially (in)effective. In this study, we primarily explored for which chronic pain patients web-based Acceptance and Commitment Therapy (ACT) was (in)effective during a large three-armed randomized controlled trial. Besides standard demographic, physical and psychosocial factors we focused on positive mental health. Data from 238 heterogeneously diagnosed chronic pain sufferers from the general Dutch population following either web-based ACT (n = 82), or one of two control conditions [web-based Expressive Writing (EW; n = 79) and Waiting List (WL; n = 77)] were analysed. ACT and EW both consisted of nine modules and lasted nine to 12 weeks. Exploratory linear regression analyses were performed using the PROCESS macro in SPSS. Pain interference at 3-month follow-up was predicted from baseline moderator (characteristics that influence the outcome of specific treatments in comparison to other treatments) and predictor (characteristics that influence outcome regardless of treatment) variables. The results showed that none of the demographic or physical characteristics moderated ACT treatment changes compared to both control conditions. The only significant moderator of change compared to both EW and WL was baseline psychological wellbeing, and pain intensity was a moderator of change compared to EW. Furthermore, higher pain interference, depression and anxiety, and also lower levels of emotional well-being predicted higher pain interference in daily life 6 months later.

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

Abstract Introduction: Integrative medicine inpatient treatment has been shown to improve physical and mental health in patients with internal medicine conditions. The aim of this study was to investigate the effectiveness of a 2-week integrative medicine inpatient treatment in patients with chronic pain syndromes and the association of treatment success with patient-related process variables. Methods: Inpatients with chronic pain syndromes participating in a 2-week integrative medicine inpatient program were included. Patients’ pain intensity, pain disability, pain perception, quality of life, depression, and perceived stress were measured on admission, discharge, and 6 months after discharge. Likewise process variables including ability and will to change, emotional/rational disease acceptance, mindfulness, life and health satisfaction, and easiness of life were assessed. Results: A total of 310 inpatients (91% female, mean age 50.7 ± 12.4 year, 26.5% low back pain, and 22.9% fibromyalgia) were included. Using mixed linear models, significant improvements in pain intensity, pain disability, pain perception, quality of life, depression, and perceived stress were found (all P medicine inpatient treatment can benefit patients with chronic pain conditions. Functional improvements are associated with improved ability to change and implementation, disease acceptance, and satisfaction. PMID:27399133

Findings considering conditioned pain modulation (CPM) in chronic back pain (CBP) are contradictory. This might be because many patients with CBP report pain in further areas of the body, and altered CPM might influence spatial extent of pain rather than CBP per se. Therefore, we compared CPM in patients with CBP with different pain extent. Patients with fibromyalgia syndrome (FMS), for whom CPM impairment is reported most consistently, were measured for comparison. Based on clinical evaluation and pain drawings, patients were categorized into chronic local back pain (CLP; n = 53), chronic widespread back pain (CWP; n = 32), and FMS (n = 92). Conditioned pain modulation was measured by the difference in pressure pain threshold (test stimuli) at the lower back before and after tonic heat pain (conditioning stimulus). We also measured psychosocial variables. Pressure pain threshold was significantly increased in CLP patients after tonic heat pain (P pain modulation in CLP was significantly higher than that in CWP and FMS (P painful areas (0-10) were associated with lower CPM (r = 0.346, P = 0.001) in CBP but not in FMS (r = -0.013, P = 0.903). Anxiety and depression were more pronounced in FMS than in CLP or CWP (P values pain inhibition seem to be more indicated the higher the pain extent.

Chronic pain is usually managed by various pharmacotherapies after exhausting the conservative modalities such as over-the-counter choices. The goal of this review is to investigate current state of opioids and non-opioid medication overuse that includes NSAIDs, skeletal muscle relaxants, antidepressants, membrane stabilization agents, and benzodiazepine. How to minimize medication overuse and achieve better outcome in chronic pain management? Although antidepressants and membrane stabilization agents contribute to the crucial components for neuromodulation, opioids were frequently designated as a rescue remedy in chronic pain since adjunct analgesics usually do not provide instantaneous relief. The updated CDC guideline for prescribing opioids has gained widespread attention via media exposure. Both patients and prescribers are alerted to respond to the opioid epidemic and numerous complications. However, there has been overuse of non-opioid adjunct analgesics that caused significant adverse effects in addition to concurrent opioid consumption. It is a common practice to extrapolate the WHO three-step analgesic ladder for cancer pain to apply in non-cancer pain that emphasizes solely on pharmacologic therapy which may result in overuse and escalation of opioids in non-cancer pain. There has been promising progress in non-pharmacologic therapies such as biofeedback, complementary, and alternative medicine to facilitate pain control instead of dependency on pharmacologic therapies. This review article presents the current state of medication overuse in chronic pain and proposes precaution to balance the risk and benefit ratio. It may serve as a premier for future study on clinical pathway for comprehensive chronic pain management and reduce medication overuse.

Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. The authors assessed people who had a diagnosis of chronic orofacial pain by using nonpain-related trait worry, state anxiety, trait anxiety, PC and pain measures. The participants' answers to an open-ended question about what they were most worried about led to the identification of worry domains, including worry about pain. The authors found that worrying about pain was related significantly to worst and least pain levels, pain interference and pain duration, as well as moderated trait worry in predicting pain interference. Although trait worry was not correlated directly with pain, when moderated by PC, it made substantial contributions in predicting pain interference. Participants with chronic orofacial pain reported experiencing substantial levels of trait worry, anxiety, PC and worry about pain that related to pain ratings directly and indirectly. Clinicians should assess pain-related worry in patients with chronic orofacial pain to understand the effects of worry on pain and functioning. Clinicians could treat these patients more effectively by helping them reduce their levels of pain-related worry and focusing on improved coping.
The issues specific to trigeminal pain include the complexity of the region, the problematic impact on daily function and significant psychological impact (J Dent, 43, 2015, 1203). By nature of the geography of the pain (affecting the face, eyes, scalp, nose, mouth), it may interfere with just about every social function we take for granted and enjoy (J Orofac Pain, 25, 2011, 333). The trigeminal nerve is the largest sensory nerve in the body, protecting the essential organs that underpin our very existence (brain, eyes, nose, mouth). It is no wonder that pain within the trigeminal system in the face is often overwhelming and inescapable for the affected individual. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We tested the hypothesis that chronic pain development (pain chronification) and ongoing chronic pain (chronic pain) reduce the activity and induce plastic changes in an endogenous analgesia circuit, the ascending nociceptive control. An important mechanism mediating this form of endogenous analgesia, referred to as capsaicin-induced analgesia, is its dependence on nucleus accumbens μ-opioid receptor mechanisms. Therefore, we also investigated whether pain chronification and chronic pain alter the requirement for nucleus accumbens μ-opioid receptor mechanisms in capsaicin-induced analgesia. We used an animal model of pain chronification in which daily subcutaneous prostaglandin E2 (PGE2) injections into the rat's hind paw for 14 days, referred to as the induction period of persistent hyperalgesia, induce a long-lasting state of nociceptor sensitization referred to as the maintenance period of persistent hyperalgesia, that lasts for at least 30 days following the cessation of the PGE2 treatment. The nociceptor hypersensitivity was measured by the shortening of the time interval for the animal to respond to a mechanical stimulation of the hind paw. We found a significant reduction in the duration of capsaicin-induced analgesia during the induction and maintenance period of persistent mechanical hyperalgesia. Intra-accumbens injection of the μ-opioid receptor selective antagonist Cys(2),Tyr(3),Orn(5),Pen(7)amide (CTOP) 10 min before the subcutaneous injection of capsaicin into the rat's fore paw blocked capsaicin-induced analgesia. Taken together, these findings indicate that pain chronification and chronic pain reduce the duration of capsaicin-induced analgesia, without affecting its dependence on nucleus accumbens μ-opioid receptor mechanisms. The attenuation of endogenous analgesia during pain chronification and chronic pain suggests that endogenous pain circuits play an important role in the development and maintenance of chronic pain.

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...

Full Text Available Objectives: This study aimed to investe the impact of pain on older people with chronic pain. Methods & Materials: Participants were 585 individuals (n=77 aged 60 years andover, n=508 aged Lessthan 60 years old with chronic pain in their leg, back, hands, neck and shoulders. The main assessment measure was the West Haven-Yale Multidimensional Pain Inventory (WHYMPI. Results: The two groups showed significant differences in three scales of important dimentions of pain experience. The old patients experienced more sever pain which effected their life, family supports and dependency. There were significant differents in three scales of evaluation and report of routin activities in the two groups. Conclusion: The old patients with chronic pain experienced more sever pain. The more sever pain, the more negative impact of pain in their life, requirement family support and dependency. Also, in the old patients with chronic pain group, the effect of chronic pain was more on outdoor activities, social and general activities than the group of usual patients with chronic pain. So, we should have more attention to general and social activities for providing care among older people with chrcnic pain than the other goups with chronic pain.

Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

Full Text Available Abstract Introduction: Chronic neck pain is associated with significant health costs and loss of productivity at work. Objective: to assess pain and disability in individuals with chronic neck pain. Methods: 31 volunteers with chronic neck pain, mean age 29, 65 years, were assessed using the McGill Pain Questionnaire in Brazilian version (Br-MPQ and Neck Disability Index (NDI. The Br-MPQ analysis was performed based on the numerical values associated with the words selected to describe the experience of pain (Pain Rating Index - PRI, and present pain intensity (PPI. NDI was used to evaluate the influence of neck pain in performance of everyday tasks. Finally, we investigated the association between PPI and NDI. Results: PRI revealed that the most significant dimension was the sensory pain (70%, and the number of chosen words was 10 (2,62 out of 20 words. Mean PPI value was 1,23 (0,76 in five points; 40% of participants described pain intensity as moderate. NDI score was 9,77 (3,34, indicating mild disability. There was a positive association between disability and pain intensity (r = 0,36; p =0,046. Pain intensity and duration of pain were not associated. Conclusions: Findings of this study identified important information related to neck pain experienced by patients when suffering from chronic neck pain, moreover, the association between disability and pain intensity reinforces the importance of complementary investigation of these aspects to optimize function in them.
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.
Non-specific chronic low back pain is an occupational hazard for nurses. It may result in persistent and disabling pain for some people. There are many techniques for investigating, assessing and treating chronic low back pain. However, research to support some of these interventions and the assumptions that underlie them is limited. Interventions that may be beneficial are not always available to those who need them. Changes to service provision are required to rectify this situation and provide effective treatment for patients with non-specific chronic low back pain.

The purpose of this review is to highlight the neighborhood, socioeconomic, and racial influences on chronic pain. Negative influences on the experience of chronic pain are explored and defined as any adverse stressor common in low socioeconomic, urban neighborhoods that potentially contributes to health disparity in African Americans experiencing chronic pain. The multifactorial influences on chronic pain disparity in African Americans are explored and expounded upon in this review of existing evidence. Databases used for the search included CINAHL, PubMed, and PsycArticles. The experience of chronic pain is multifaceted, existing with multiple comorbidities and lasting consequences. To improve the burden of chronic pain requires a multifactorial assessment that considers neighborhood risk factors, emphasis on environmental stressors, limitations to support networks, barriers to physical activity, and access to primary care providers with whom communication is open and without bias. A comprehensive assessment of barriers will aid in the development of interventions that reach beyond the physical factors of chronic pain, also considering the psychosocial barriers to improving the burden of chronic pain in African Americans living in impoverished urban neighborhoods.

BACKGROUND: In contrast to the well-described 10% risk of chronic pain affecting daily activities after adult groin hernia repair, chronic pain after childhood groin hernia repair has never been investigated. Studies of other childhood surgery before the age of 3 months suggest a risk of increased...... pain responsiveness later in life, but its potential relationship to chronic pain in adult life is unknown. METHODS: This was a nationwide detailed questionnaire study of chronic groin pain in adults having surgery for a groin hernia repair before the age of 5 years (n = 1075). RESULTS: The response...... rate was 63.3%. In the 651 patients available for analysis, pain from the operated groin was reported by 88 (13.5%) patients whereof 13 (2.0%) patients reported frequent and moderate or severe pain. Pain occurred primarily when exercising sports or other leisure activities. Patients operated on before...

Pain in the spine is the most frequently described pain problem in primary care, afflicting at least 54 million Americans. When spinal pain becomes chronic, the prognosis for recovery is poor, often leading to disability and reduced quality of life. Clinical treatment is inadequate, often focusing on physical pathology alone. To improve treatment outcomes for chronic pain as recommended by current guidelines, the Biobehavioral Pain Profile (BPP), which includes six pain response subscales, was developed to guide cognitive behavioral therapy (CBT). The purpose of this study was to describe the BPP in 100 individuals with chronic spine pain and examine the associations between the BPP and important clinical outcomes, including chronic pain, disability, and quality of life. Participants reported a high level of pain, a low quality of life, and a high level of disability despite receiving treatment with opioids. Scores on BPP subscales including evaluating loss of control, past and current experience, physiologic responsivity, and thoughts of disease progression were elevated, indicating a need for CBT. Five of the six BPP subscales had a significant association with quality of life, chronic pain, and disability with the thought of disease progression being a strong factor for most of the clinical outcome variables. By identifying BPP, clinicians can provide appropriate treatments to improve individuals' quality of life and prevent further disability. Further study using the BPP to guide CBT is needed.

Spinal cord stimulation (SCS) is thought to relieve chronic intractable pain by stimulating nerve fibers in the spinal cord. The resulting impulses in the fibers may inhibit the conduction of pain signals to the brain, according to the pain gate theory proposed by Melzack and Wall in 1965 and the sensation of pain is thus blocked. Although SCS may reduce pain, it will not eliminate it. After a period of concern about safety and efficacy, SCS is now regaining popularity among pain specialists for the treatment of chronic pain. The sympatholytic effect of SCS is one of its most interesting therapeutic properties. This effect is considered responsible for the effectiveness of SCS in peripheral ischemia, and at least some cases of complex regional pain syndrome. The sympatholytic effect has also been considered part of the management of other chronic pain states such as failed back surgery syndrome, phantom pain, diabetic neuropathy, and postherpetic neuralgia. In general, SCS is part of an overall treatment strategy and is used only after the more conservative treatments have failed. The concept of SCS has evolved rapidly following the technological advances that have produced leads with multiple contact electrodes and battery systems. The current prevalence of patients with chronic pain requiring treatment other than conventional medical management has significantly increased and so has been the need for SCS. With the cost benefit analysis showing significant support for SCS, it may be appropriate to offer this as an effective alternative treatment for these patients.
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 constitutes a challenge for patients. It makes them uneasy with regard to their personality, their corporality and their life balance, and leaves long-lasting effects on their experience as a patient. The development of adaptation strategies and resources to deal with chronic pain is therefore essential. Copyright © 2017 Elsevier Masson SAS. All rights reserved.
The pain of chronic pancreatitis represents a major challenge to those working in the field, including pain specialists, gastroenterologists and surgeons. This article describes the different aetiologies of chronic pancreatitis and lists the models for the pathogenesis of pain, including novel ideas such as the role of the immune system in the modulation of pain. The patient profile in chronic pancreatitis is discussed along with the social impact of the disease in relation to alcohol misuse. The range of treatment strategies including medical, endoscopic and surgical approaches are evaluated. Common analgesic regimes and their limitations are reviewed. The pain of chronic pancreatitis remains refractory to effective treatment in many cases and further study and understanding of the underlying pathophysiology are required. PMID:26516493

Full Text Available The paper gives an account of approaches to treating patients with acute and chronic back pain in the context of evidence-based medicine and current clinical guidelines. In the vast majority, acute back pain is a benign self-limiting condition (nonspecific musculoskeletal pain and most patients need additional instrumental examinations. An active approach to treatment is considered to be optimal. It is expedient to apply a more differential approach involving the refinement of mechanisms for development of the pain syndrome and the elaboration of treatment strategy in relation to the leading pathophysiological mechanism when examining the patients with chronic back pain.

Assessment of physical and psychosocial dysfunction is recognized as essential in chronic pain patient evaluation. One instrument, the Sickness Impact Profile (SIP), has demonstrated good reliability and validity as a measure of dysfunction among chronic pain patients. An alternate measure, the Chronic Illness Problem Inventory (CIPI), is shorter and more easily scored than the SIP, but as yet has not been applied widely to chronic pain problems. In the present study, 95 chronic low back pain patients completed the SIP, the CIPI, activity diaries, the McGill Pain Questionnaire (MPQ), and the Center for Epidemiologic Studies-Depression scale (CES-D), before participating in a chronic pain treatment study. Overt pain behaviors were also coded from videotapes of a standardized assessment protocol. Seventy-five subjects completed the measures post-treatment. The results indicate that although the SIP and the CIPI are significantly correlated and appear to be measuring similar constructs, there is also substantial unshared variance between them, suggesting that they may tap somewhat different aspects of dysfunction in chronic pain. The CIPI shows promise as a useful alternative measure of dysfunction in chronic low back pain patients, but requires further validation for this purpose.

Full Text Available Chronic pain can be understood not only as an altered functional state, but also as a consequence of neuronal plasticity. Here we use in vivo structural MRI to compare global, local, and architectural changes in gray matter properties in patients suffering from chronic back pain (CBP, complex regional pain syndrome (CRPS and knee osteoarthritis (OA, relative to healthy controls. We find that different chronic pain types exhibit unique anatomical 'brain signatures'. Only the CBP group showed altered whole-brain gray matter volume, while regional gray matter density was distinct for each group. Voxel-wise comparison of gray matter density showed that the impact on the extent of chronicity of pain was localized to a common set of regions across all conditions. When gray matter density was examined for large regions approximating Brodmann areas, it exhibited unique large-scale distributed networks for each group. We derived a barcode, summarized by a single index of within-subject co-variation of gray matter density, which enabled classification of individual brains to their conditions with high accuracy. This index also enabled calculating time constants and asymptotic amplitudes for an exponential increase in brain re-organization with pain chronicity, and showed that brain reorganization with pain chronicity was 6 times slower and twice as large in CBP in comparison to CRPS. The results show an exuberance of brain anatomical reorganization peculiar to each condition and as such reflecting the unique maladaptive physiology of different types of chronic pain.

It has been reported that oscillatory gamma activity participates in brief acute pain and tonic ongoing pain. It is of great interest to determine whether the gamma activity is involved in chronic pain since chronic pain is a more severe pathological condition characterized by pain persistency. To investigate the oscillatory gamma activity in chronic pain, in the present study, we recorded spontaneous electrocorticogram (ECoG) signals during chronic pain development in rats with chronic infla...

In this paper, we review the association between obesity and pain in the general population as well as chronic pain patients. We also review the relationship between obesity and pain response to noxious stimulation in animals and humans. Based upon the existing research, we present several potential mechanisms that may link the two phenomena, including mechanical/structural factors, chemical mediators, depression, sleep, and lifestyle. We discuss the clinical implications of obesity and pain, focusing on the effect of weight loss, both surgical and noninvasive, on pain. The literature suggests that the two conditions are significant comorbidities, adversely impacting each other. The nature of the relationship however is not likely to be direct, but many interacting factors appear to contribute.

This article reviews controlled prospective trials of hypnosis for the treatment of chronic pain. Thirteen studies, excluding studies of headaches, were identified that compared outcomes from hypnosis for the treatment of chronic pain to either baseline data or a control condition. The findings indicate that hypnosis interventions consistently produce significant decreases in pain associated with a variety of chronic-pain problems. Also, hypnosis was generally found to be more effective than nonhypnotic interventions such as attention, physical therapy, and education. Most of the hypnosis interventions for chronic pain include instructions in self-hypnosis. However, there is a lack of standardization of the hypnotic interventions examined in clinical trials, and the number of patients enrolled in the studies has tended to be low and lacking long-term follow-up. Implications of the findings for future clinical research and applications are discussed. PMID:17558718

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

Chronic pain can be a frustrating condition for patient and clinician. The integrative medicine approach to pain can offer hope, adding safe complementary and alternative medical (CAM) therapies to mitigate pain and suffering. Such CAM therapies include nutrition, supplements and herbs, manual medicine, acupuncture, yoga, and mind-body approaches. The evidence is heterogeneous regarding these approaches, but some evidence suggests efficacy and confirms safety. The integrative medicine approach can be beneficial in a patient with chronic pain.

Much confusion has surrounded the purpose of the psychological assessment in the context of chronic pain. For many clinicians, the psychological assessment is used to rule out psychiatric illness and to identify the nonmedical causes for pain and disability. In essence, it is used to identify the causes of pain that fall outside of the biomedical model. Supported by over 30 years of evidence, the bio-psycho-social model acknowledges that psychosocial factors are inherent in chronic pain and require assessment if meaningful diagnostics and treatments are to occur. Five broad categories of psychosocial assessment are relevant to chronic pain. These categories have been shown to enhance the diagnosis of the underlying forms of pain, predict the transition from acute to chronic status, and help to phenotype individuals for the discovery of the underlying mechanisms responsible for pain. Informed assessment of chronic pain needs to include relevant biological, psychological, and social domains. This article describes those domains and offers suggestions of specific instruments to use in clinical or research settings.

The overall population impact of chronic pain on work performance has been underestimated as it has often been described in terms of work-related absence, excluding more subtle effects that chronic pain may have on the ability to work effectively. Additionally, most studies have focussed on occupational and/or patient cohorts and treatment seeking, rather than sampling from the general population. We undertook a population-based random digit dialling computer-assisted telephone survey with participants randomly selected within households in order to measure the impact of chronic pain on work performance. In addition, we measured the association between pain-related disability and litigation. The study took place in Northern Sydney Health Area, a geographically defined urban area of New South Wales, Australia, and included 484 adults aged 18 or over with chronic pain. The response rate was 73.4%. Working with pain was more common (on an average 83.8 days in 6 months) than lost work days due to pain (4.5 days) among chronic pain participants in full-time or part-time employment. When both lost work days and reduced-effectiveness work days were summed, an average of 16.4 lost work day equivalents occurred in a 6-month period, approximately three times the average number of lost work days. In multiple logistic regression modelling with pain-related disability as the dependent variable, past or present pain-related litigation had the strongest association (odds ratio (OR)=3.59, P=0.001). In conclusion, chronic pain had a larger impact on work performance than has previously been recognised, related to reduced performance while working with pain. A significant proportion were able to work effectively with pain, suggesting that complete relief of pain may not be an essential therapeutic target. Litigation (principally work-related) for chronic pain was strongly associated with higher levels of pain-related disability, even after taking into account other factors

Some comparisons are made between tomodensitometry, nuclear magnetic imaging, the disco-scanner, these technologies allow to find small lesions but the problem is complete when it is not possible to find anything with persistent pains. 125 refs
Full Text Available Abstract An understanding of how the brain changes in chronic pain or responds to pharmacological or other therapeutic interventions has been significantly changed as a result of developments in neuroimaging of the CNS. These developments have occurred in 3 domains : (1 Anatomical Imaging which has demonstrated changes in brain volume in chronic pain; (2 Functional Imaging (fMRI that has demonstrated an altered state in the brain in chronic pain conditions including back pain, neuropathic pain, and complex regional pain syndromes. In addition the response of the brain to drugs has provided new insights into how these may modify normal and abnormal circuits (phMRI or pharmacological MRI; (3 Chemical Imaging (Magnetic Resonance Spectroscopy or MRS has helped our understanding of measures of chemical changes in chronic pain. Taken together these three domains have already changed the way in which we think of pain – it should now be considered an altered brain state in which there may be altered functional connections or systems and a state that has components of degenerative aspects of the CNS.
Full Text Available Kristoffer Andresen, Jacob Rosenberg Department of Surgery, Herlev Hospital, University of Copenhagen, Copenhagen, Denmark Abstract: Chronic pain following inguinal hernia repair is a common problem and feared complication. Up to 16% of people experience chronic pain following the repair of a groin hernia. The aim of this review was to provide an overview of treatment strategies for patients with chronic pain following inguinal hernia repair based on best practice guidelines and current clinical routines. The optimal management of chronic pain following inguinal hernia surgery should begin with a thorough clinical examination to rule out other causes of chronic pain and to rule out a recurrence. A scaled approach to treatment is recommended. Initially, watchful waiting can be tried if it can be tolerated by the patient and then systemic painkillers, escalating to blocks, and surgery as the final option. Surgery should include mesh removal and triple neurectomy following anterior approaches or mesh and tack removal following a posterior approach. The diagnosis and treatment strategies should be performed by or discussed with experts in the field. Keywords: inguinal hernia, chronic pain, management, surgery, pharmacology, radio frequency

Activation of glial cells and neuro-glial interactions are emerging as key mechanisms underlying chronic pain. Accumulating evidence has implicated 3 types of glial cells in the development and maintenance of chronic pain: microglia and astrocytes of the central nervous system (CNS), and satellite glial cells of the dorsal root and trigeminal ganglia. Painful syndromes are associated with different glial activation states: (1) glial reaction (ie, upregulation of glial markers such as IBA1 and glial fibrillary acidic protein (GFAP) and/or morphological changes, including hypertrophy, proliferation, and modifications of glial networks); (2) phosphorylation of mitogen-activated protein kinase signaling pathways; (3) upregulation of adenosine triphosphate and chemokine receptors and hemichannels and downregulation of glutamate transporters; and (4) synthesis and release of glial mediators (eg, cytokines, chemokines, growth factors, and proteases) to the extracellular space. Although widely detected in chronic pain resulting from nerve trauma, inflammation, cancer, and chemotherapy in rodents, and more recently, human immunodeficiency virus-associated neuropathy in human beings, glial reaction (activation state 1) is not thought to mediate pain sensitivity directly. Instead, activation states 2 to 4 have been demonstrated to enhance pain sensitivity via a number of synergistic neuro-glial interactions. Glial mediators have been shown to powerfully modulate excitatory and inhibitory synaptic transmission at presynaptic, postsynaptic, and extrasynaptic sites. Glial activation also occurs in acute pain conditions, and acute opioid treatment activates peripheral glia to mask opioid analgesia. Thus, chronic pain could be a result of "gliopathy," that is, dysregulation of glial functions in the central and peripheral nervous system. In this review, we provide an update on recent advances and discuss remaining questions. Copyright © 2013 International Association for the

Pain is one of the most ubiquitous problems of today's world, its impact being far-reaching. Current conceptualizations of pain medicine adopt a bio-psycho-social perspective. In this model, pain is best described as an interactive, psycho-physiological behavioral pattern that cannot be divided into independent psycho-social and physical components. Neurophysiologic substrates of the pain experience can be broken down into the pain transmission elements emanating from peripheral, spinal, and supra-spinal processes. There are many complex mechanisms involved in pain processing within the central nervous system, being influenced by genetics, interaction of neurotransmitters and their receptors, and pain- augmenting and pain-inhibiting neural circuits. The patient's emotional experiences, beliefs and expectations may determine the outcome of treatment, and are fully emphasized in the focus of treatment interventions. There are several common psychiatric disorders accompanying and complicating the experience of pain that warrant clinical attention and that can be the focus of psychiatric treatment. These include depression, anxiety, sleep disorders, somatoform disorders, substance-related disorders and personality disorders. Complex and disabling pain conditions often require comprehensive pain treatment programs, involving interdisciplinary and multimodal treatment approaches. There are many roles that the psychiatrist can perform in the assessment and treatment of the patients with pain, individually tailored to meet the specific needs of the patient. Rational poly-pharmacy is of a high importance in the treatment of patients with chronic pain, with antidepressants and anticonvulsants contributing as the important adjuvant analgesic agents.

This article discusses several issues related to therapies that are considered "complementary" or "alternative" to conventional medicine. A definition of "complementary and alternative medicine" (CAM) is considered in the context of the evolving health care field of complementary medicine. A rationale for pain physicians and clinicians to understand these treatments of chronic pain is presented. The challenges of an evidence-based approach to incorporating CAM therapies are explored. Finally, a brief survey of the evidence that supports several widely available and commonly used complementary therapies for chronic pain is provided. Copyright © 2015 Elsevier Inc.

Full Text Available Chronic pain is common, often widespread and has a substantial impact on health and quality of life. The relationship between chronic pain and mortality is unclear. This systematic review aimed to identify and evaluate evidence for a relationship between chronic pain and mortality.A search of ten electronic databases including EMBASE and MEDLINE was conducted in March 2012, and updated until March 2014. Observational studies investigating the association between chronic or widespread pain (including fibromyalgia and mortality were included. Risk of bias was assessed and a meta-analysis was undertaken to quantify heterogeneity and pool results. A narrative review was undertaken to explore similarities and differences between the included studies.Ten studies were included in the review. Three reported significant associations between chronic or widespread pain and mortality in unadjusted results. In adjusted analyses, four studies reported a significant association. The remaining studies reported no statistically significant association. A meta-analysis showed statistically significant heterogeneity of results from studies using comparable outcome measures (n = 7(I2 = 78.8% and a modest but non-significant pooled estimate (MRR1.14,95%CI 0.95-1.37 for the relationship between chronic pain and all-cause mortality. This association was stronger when analysis was restricted to studies of widespread pain (n = 5,I2 = 82.3% MRR1.22(95%CI 0.93-1.60. The same pattern was observed with deaths from cancer and cardiovascular diseases. Heterogeneity is likely to be due to differences in study populations, follow-up time, pain phenotype, methods of analysis and use of confounding factors.This review showed a mildly increased risk of death in people with chronic pain, particularly from cancer. However, the small number of studies and methodological differences prevented clear conclusions from being drawn. Consistently applied definitions of

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. © 2017 American Physical Therapy Association.

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.
Full Text Available Background: People who suffer from chronic pain are thought to have lower levels of physical activity compared to healthy individuals. However, there is a lack of evidence concerning levels of physical activity in South Africans with chronic pain. Objectives: To compare levels of physical activity in a South African sample of people with chronic pain compared to matched controls. Methods: A cross-sectional study was conducted with 24 participants (12 with chronic pain and 12 in the control group matched for age, gender and residential area. Convenience sampling was used. The participants with chronic pain (12 were identified from the Groote Schuur Hospital, Chronic Pain Management Clinic (CPMC waiting list and had not yet received any chronic pain management intervention. Healthy matched controls were selected from volunteers in the community. With the desired alpha level set at 0.05 and the power at 0.9, 45 participants were required to detect a minimum of a 50 per cent difference between groups in levels of physical activity as measured in steps per day using pedometers. The international physical activity questionnaire (IPAQ and the brief pain inventory (BPI were used as measures of physical activity and pain. Objective indicators of physical activity that were used included the 6-minute walk test (6MWT, repeated sit-to-stand test (RSST, 7 days of pedometry and body mass index (BMI. Results: The chronic pain group performed significantly worse on the 6MWT (335 m [30–430] vs 680 m [430–795]; U = 0.5; p < 0.01 and on the RSST (17.9 s [11.83–105] vs 7.85 s [5.5–11.5]; U = 0; p < 0.01. The chronic pain group also had significantly lower scores on pedometry (mean daily: 2985.1 [32.8–13785.4] vs 6409.4 [4207.1–15313.6]; U = 35; p < 0.03.

The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

The contribution of rib fractures to chronic pain and disability is not well described. Two hundred three patients with rib fractures were followed for 6 months. Chronic pain was assessed using the McGill Pain Questionnaire Pain Rating Index and Present Pain Intensity (PPI) scales. Disability was defined as a decrease in work or functional status. The prevalence of chronic pain was 22% and disability was 53%. Acute PPI predicted chronic pain. Associated injuries, bilateral rib fractures, injury severity score, and number of rib fractures were not predictive of chronic pain. No acute injury characteristics were predictive of disability. Among 89 patients with isolated rib fractures, the prevalence of chronic pain was 28% and of disability was 40%. No injury characteristics predicted chronic pain. Bilateral rib fractures and acute PPI predicted disability. The contribution of rib fractures to chronic pain and disability is significant but unpredictable with conventional injury descriptors.

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.

The following conclusions can be made based on review of the evidence: There is limited but positive evidence that select physical modalities are effective in managing chronic pain associated with specific conditions experienced by adults and older individuals. Overall, studies have provided the most support for the modality of therapeutic exercise. Different physical modalities have similar magnitudes of effects on chronic pain. Therefore, selection of the most appropriate physical modality may depend on the desired functional outcome for the patient, the underlying impairment, and the patient's preference or prior experience with the modality. Certain patient characteristics may decrease the effectiveness of physical modalities, as has been seen with TENS. These characteristics include depression, high trait anxiety, a powerful others locus of control, obesity, narcotic use, and neuroticism. The effect on pain by various modalities is generally strongest in the short-term period immediately after the intervention series, but effects can last as long as 1 year after treatment (e.g., with massage). Most research has tested the effect of physical modalities on chronic low back pain and knee OA. The effectiveness of physical modalities for other chronic pain conditions needs to be evaluated more completely. Older and younger adults often experience similar effects on their perception of pain from treatment with physical modalities. Therefore, use of these modalities for chronic pain in older adults is appropriate, but special precautions need to be taken. Practitioners applying physical modalities need formal training that includes the risks and precautions for these modalities. If practitioners lack formal training in the use of physical modalities, or if modality use is not within their scope of practice, it is important to consult with and refer patients to members of the team who have this specialized training. Use of a multidisciplinary approach to chronic pain

People from different cultures who speak different languages may experience pain differently. 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. 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. 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, depending on the measure in question. The findings indicate that direct translations of measures that are developed using samples of patients from one country or culture are not necessarily content valid for use in other countries or cultures; some adaptations may be required in order for such measures to be most useful in new language and culture.

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.

During pregnancy most of women will experience some kind of pain, either as a result of a pre-existing condition (low back pain, headache, fibromyalgia, and rheumatoid arthritis) or as a direct consequence of pregnancy (weight gain, postural changes, pelvic floor dysfunction, hormonal factors). However, chronic pain management during pregnancy and lactation remains a challenge for clinicians and pregnant women are at risk of undertreatment for painful conditions, because of fear about use of drugs during pregnancy. Few analgesic drugs have been demonstrated to be absolutely contraindicated during pregnancy and breastfeeding, but studies in pregnant women are not available for most of pain medications. The aim of this paper is to review the safety profile in pregnancy or lactation of the commonly prescribed pain medications and non-pharmacological treatments. In addition to the conventional classifications from the Food and Drug Administration and the American Academy of Paediatrics, authors analyzed the currently available clinical data from literature.

Whether chronic localized pain (CLP) and chronic widespread pain (CWP) have different mechanisms or to what extent they overlap in their pathophysiology is controversial. The study compared quantitative sensory testing profiles of nonspecific chronic back pain patients with CLP (n=48) and CWP (n=29) with and fibromyalgia syndrome (FMS) patients (n=90) and pain-free controls (n = 40). The quantitative sensory testing protocol of the "German-Research-Network-on-Neuropathic-Pain" was used to measure evoked pain on the painful area in the lower back and the pain-free hand (thermal and mechanical detection and pain thresholds, vibration threshold, pain sensitivity to sharp and blunt mechanical stimuli). Ongoing pain and psychometrics were captured with pain drawings and questionnaires. CLP patients did not differ from pain-free controls, except for lower pressure pain threshold (PPT) on the back. CWP and FMS patients showed lower heat pain threshold and higher wind-up ratio on the back and lower heat pain threshold and cold pain threshold on the hand. FMS showed lower PPT on back and hand, and higher comorbidity of anxiety and depression and more functional impairment than all other groups. Even after long duration CLP presents with a local hypersensitivity for PPT, suggesting a somatotopically specific sensitization of nociceptive processing. However, CWP patients show widespread ongoing pain and hyperalgesia for different stimuli that is generalized in space, suggesting the involvement of descending control systems, as also suggested for FMS patients. Because mechanisms in nonspecific chronic back pain with CLP and CWP differ, these patients should be distinguished in future research and allocated to different treatments.

OBJECTIVE: This randomized controlled clinical trial investigated the effects of mindfulness meditation on chronic pain. DESIGN: A total of 109 patients with nonspecific chronic pain were randomized to either a standardized mindfulness meditation program (mindfulness-based stress reduction [MBSR...... randomized patients completed the mindfulness program, while 47 remained in the control group. Data were compared at three time points: at baseline, after completion of the course/waiting period, and at the 6-month follow-up. RESULTS: Significant effect (Cohen's d = 0.39) was found on the primary outcome...... (nonsignificant) effect sizes were found for pain measures. There were no significant differences in the measures just after the intervention vs the 6-month follow-up. CONCLUSION: A standardized mindfulness program (MBSR) contributes positively to pain management and can exert clinically relevant effects...

Healthy humans can be divided into the pain adaptive (PA) and the pain nonadaptive (PNA) groups; PA showed a greater decrease in pain rating to a cold pressor test (CPT) than PNA. This study examined if the dichotomy of pain adaptability existed in individuals with chronic musculoskeletal pain. CPTs at 2°C and 7°C were used to assess the status of pain adaptability in participants with either chronic nonspecific low back pain or knee osteoarthritis. The participants' potency of conditioned pain modulation (CPM) and local inhibition were measured. The strengths of pain adaptability at both CPTs were highly correlated. PA and PNA did not differ in their demographic characteristics, pain thresholds from thermal and pressure stimuli, or potency of local inhibition or CPM. PA reached their maximum pain faster than PNA (t 41 = -2.76, P adaptability exists in musculoskeletal pain patients. Consistent with the healthy human study, the strength of pain adaptability and potency of CPM are not related. Pain adaptability could be another form of endogenous pain inhibition of which clinical implication is yet to be understood. The dichotomy of pain adaptability was identified in healthy humans. The current study confirms that this dichotomy also exists in individuals with chronic musculoskeletal pain, and could be reliably assessed with CPTs at 2°C and 7°C. Similar to the healthy human study, pain adaptability is not associated with CPM, and may reflect the temporal aspect of pain inhibition. Copyright © 2018 The American Pain Society.

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.

Sleep is a vital function for human beings, which can be affected by several factors. Chronic pain is one of these factors where it is the most frequent cause for seeking medical care in combination with insomnia. The aim of this study is to examine the prevalence and relationship between sleep disturbance and chronic pain. After approval, a total of 85 Family Medicine Units from over 170 in Tokat were randomly selected using a 50% sampling. A sample of 2635 subjects, over the age of 19 years, who were registered with the selected Family Medicine Units, were assessed due to gender, age group, and the urban/rural population size of Tokat using the stratified sampling method. The sample size distribution was calculated as 1515 urban subjects, 1120 rural subjects; 1345 female subjects, 1290 male subjects; 1123 subjects between 20-39 years of age, 1103 subjects between the ages of 40-64, and 409 subjects over 64 years of age. After sampling, subjects were invited to participate in the study via an invitation letter, and agreeing individuals were taken to the Family Medicine Unit for face-to-face meetings. Written, informed consent was obtained, along with demographic data. The presence of chronic pain was recorded. According to the presence of chronic pain, all subjects were separated into two groups as Group Chronic Pain and Group Non-Chronic Pain. The visual analog scale for pain intensity, and Pittsburgh Sleep Quality Index for sleep quality, were performed with all subjects. A multiple linear regression model was used to assess the predictors of sleep quality. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA), version 20.0. The statistical significance for all analyses was set at p 5. A moderate positive correlation was found between the global Pittsburgh Sleep Quality Index and Visual Analog Scale scores (r = 0.310, p < 0.01). A multiple linear regression analysis showed that age, gender, income, Visual

The National Academies of Sciences, Engineering, and Medicine has found substantial evidence that cannabis (plant) is effective for the treatment of chronic pain in adults, and moderate evidence that oromucosal cannabinoids (extracts, especially nabiximols) improve short-term sleep disturbances in chronic pain. The paradoxical superiority of the cannabis plant over cannabinoid molecules represents a challenge for the medical community and the established processes that define modern pharmacy. The expanding and variable legalization of cannabis in multiple states nationwide represents an additional challenge for patients and the medical community because recreational and medicinal cannabis are irresponsibly overlapped. Cannabis designed for recreational use (containing high levels of active ingredients) is increasingly available to patients with chronic pain who do not find relief with current pharmacologic entities, which exposes patients to potential harm. This article analyzes the available scientific evidence to address controversial questions that the current state of cannabis poses for health-care professionals and chronic pain patients, and sets the basis for a more open discussion about the role of cannabis in modern medicine for pain management. A critical discussion on these points, the legal status of cannabis, and considerations for healthcare providers is presented. This article is protected by copyright. All rights reserved.

Full Text Available Chronic pelvic pain syndrome (CPPS is a chronic pain disease with high prevalence rates. The etiology and pathogenesis of this problem remains poorly understood. No uniform solitary treatment is known for CPPS. As a result, a multimodal approach is most likely to demonstrate benefit for this disease. An interdisciplinary classification system is commonly used (UPOINT which includes psychosocial domain. Nevertheless, psychosocial and psychopathological influences on CPPS only recently became a research focus. This literature review investigated the association of personality traits, mental disorders with the baseline clinical characteristics of patients with CPPS. We aimed to synthesize the existing data and to identify further research topics.

The anaesthetic ketamine is used to treat various chronic pain syndromes, especially those that have a neuropathic component. Low dose ketamine produces strong analgesia in neuropathic pain states, presumably by inhibition of the N-methyl-D-aspartate receptor although other mechanisms are possibly involved, including enhancement of descending inhibition and anti-inflammatory effects at central sites. Current data on short term infusions indicate that ketamine produces potent analgesia during administration only, while three studies on the effect of prolonged infusion (4–14 days) show long-term analgesic effects up to 3 months following infusion. The side effects of ketamine noted in clinical studies include psychedelic symptoms (hallucinations, memory defects, panic attacks), nausea/vomiting, somnolence, cardiovascular stimulation and, in a minority of patients, hepatoxicity. The recreational use of ketamine is increasing and comes with a variety of additional risks ranging from bladder and renal complications to persistent psychotypical behaviour and memory defects. Blind extrapolation of these risks to clinical patients is difficult because of the variable, high and recurrent exposure to the drug in ketamine abusers and the high frequency of abuse of other illicit substances in this population. In clinical settings, ketamine is well tolerated, especially when benzodiazepines are used to tame the psychotropic side effects. Irrespective, close monitoring of patients receiving ketamine is mandatory, particularly aimed at CNS, haemodynamic, renal and hepatic symptoms as well as abuse. Further research is required to assess whether the benefits outweigh the risks and costs. Until definite proof is obtained ketamine administration should be restricted to patients with therapy-resistant severe neuropathic pain. PMID:23432384

as it could be'. Pain types were similar to 7-years follow-up but remained higher than baseline. There was a significant deterioration in quality of life in those with more severe CPG over time. Almost half of the participants 31 (44%) required care either from a private carer, institution or from a family member. Although fear of taking medications and side effects were common barriers to treatment for pain, there was an increase in the use of pharmacological treatment over time and an increase in the use of healthcare services, mainly neurologists and general practitioners. The pain measures reported by the participants were similar to those at the 7-year follow-up except there was a greater representation of bilateral pain locations (limb, trunk and facial pain) compared to baseline and 7-year follow-up. At 10-year follow-up, more participants used medications compared to 7-year follow-up and there was an increase in the use of health professionals at the 10-year follow-up. At the 10-year follow up QoL of the participants deteriorated significantly and more participants had progressed to higher CPG III and CPG IV. This study demonstrates that chronic pain is a significant issue over time in MS, with clinical and health implications, impact on quality of life, disability and healthcare utilization. Greater awareness of chronic pain in pwMS, cognitive classifications and an interdisciplinary approach is required to improve long-term patient outcomes and well-being. Crown Copyright © 2017.

Temporomandibular disorders (TMDs) are a major cause of non-dental orofacial pain with a suggested prevalence of 3% to 5% in the general population. TMDs present as unilateral or bilateral pain centered round the pre-auricular area and can be associated with clicking and limitation in jaw movements. It is important to ascertain if there are other comorbid factors such as headaches, widespread chronic pain and mood changes. A biopsychosocial approach is crucial with a careful explanation and self-care techniques encouraged.

Dysregulation of pain neurocircuitry and neurochemistry has been increasingly recognized as playing a critical role in a diverse spectrum of diseases including migraine, fibromyalgia, depression, and PTSD. Evidence presented here supports the hypothesis that alcohol dependence is among the pathologies arising from aberrant neurobiological substrates of pain. In this review, we explore the possible influence of alcohol analgesia and hyperalgesia in promoting alcohol misuse and dependence. We examine evidence that neuroanatomical sites involved in the negative emotional states of alcohol dependence also play an important role in pain transmission and may be functionally altered under chronic pain conditions. We also consider possible genetic links between pain transmission and alcohol dependence. We propose an allostatic load model in which episodes of alcohol intoxication and withdrawal, traumatic stressors, and injury are each capable of dysregulating an overlapping set of neural substrates to engender sensory and affective pain states that are integral to alcohol dependence and comorbid conditions such as anxiety, depression, and chronic pain.

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

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.

The objectives of this study were to investigate whether continuous intravenous ketamine during the first 72 hours after thoracotomy could reduce the incidence and intensity of chronic postthoracotomy pain (CPTP) and to define the incidence and risk factors of CPTP. Seventy-eight patients receiving thoracotomy for lung tumor (benign or malignant) were randomly divided into two groups: ketamine group (n = 31) and control groups (n = 47). Patients in the ketamine group received intravenous ketamine 1 mg/kg before incision, followed by 2 μg/kg/minute infusion for 72 hours plus sufentanil patient-controlled intravenous analgesia after thoracotomy. Patients in the control group received intravenous a 0.9% normal saline and infusion plus sufentanil patient-controlled intravenous analgesia. The solutions patients received were blinded. The numerical rating scale (NRS) pain scores and the incidence and risk factors of CPTP were recorded during the first 6 months after surgery. Compared with control group, the incidence of chronic pain in the ketamine group did not decrease at 2 months (χ(2) = 1.599, P = .206) and 6 months (χ(2) = 0.368, P = .544) after surgery. Postoperative pain scores in the ketamine group were not significantly different from those of the control group patients at 2 months (U = 677.5, P = .593) and 6 months (U = 690.5, P = .680). The incidence of CPTP was 78.2% (61/78) at 2 months and 53.8% (42/78) at 6 months after surgery. Retractor used time (OR = 5.811, P = .002), inadequate acute pain control (NRS ≥ 5) (OR = 5.425, P = .048), and chemotherapy (OR = 3.784, P = .056) were independent risk factors for chronic postthoracotomy pain. The authors conclude that continuous intravenous ketamine (2 μg/kg/min) during the first 72 hours after thoracotomy was not beneficial to prevent chronic postthoracotomy pain. The independent risk factors for chronic postthoracotomy pain were retractor used time, inadequate acute pain control, and chemotherapy.

Chronic pain has high comorbidity with psychiatric disorders, therefore, better understanding of the relationship between chronic pain and mental illness is needed. This study aimed to investigate the pathway relationships among parental attachment, personality characteristics, alexithymic trait and mental health in patients with chronic widespread pain, those with chronic regional pain, and controls. Two hundred and thirty participants were recruited. The parental Bonding Inventory, Eysenck Personality Inventory (EPI), 20-item Toronto Alexithymia Scale (TAS-20), Chinese Health Questionnaire, and Short-Form 36 were filled out. The pathway relationships revealed that patients of mothers who were more protective were more neurotic, had more difficulty identifying feelings (DIF), worse mental health, and a higher association with chronic widespread pain. No differences were found between patients with chronic regional pain and the controls. The predisposing factors for chronic widespread pain, when compared with chronic regional pain, may be more closely related to psychiatric disorders. The pathways to chronic regional pain and chronic widespread pain differ, with neuroticism and the alexithymic DIF trait being the main factors defining chronic widespread pain. Therefore, besides therapies targeting pain symptoms, psychiatric consultation, medication and psychotherapy are also recommended for those with chronic widespread pain to alleviate their mental health conditions.

An overview is given on the current classification, description and treatment of chronic pain with causally relevant psychological factors. It is based on the "practice guidelines on somatoform disorders" and on a thematically related meta-analysis. The classificatory problems, especially of the demarcation of somatoform and other chronic pain, are presented. Additional descriptive dimensions of the relevant psychosocial factors are: pain description, other organically unexplained pain- and non-pain-symptoms, anxiety and depression, disease conviction and illness behaviour, personality and childhood abuse. A modified psychotherapy for (somatoform) chronic pain is outlined. Finally, this aetiologically oriented psychosomatic-psychiatric approach is compared to psychological coping models for chronic pain.

BACKGROUND/STUDY CONTEXT: Chronic pain is associated with increased interference in daily functioning that becomes more pronounced as pain intensity increases. Based on previous research showing that older adults maintain well-being in the face of pain as well as or better than their younger counterparts, the current study examined the interaction of age and pain intensity on interference in a sample of chronic orofacial pain patients. Data were obtained from the records of 508 chronic orofacial pain patients being seen for an initial evaluation from 2008 to 2012. Collected data included age (range: 18-78) and self-reported measures of pain intensity and pain interference. Bivariate correlations and regression models were used to assess for statistical interactions. Regression analyses revealed that pain intensity positively predicted pain interference (R(2) = .35, B = 10.40, SE = 0.62, t(507) = 16.70, p theories, including socioemotional selectivity theory, which posits that as people age, they become more motivated to maximize positive emotions and minimize negative ones. The results highlight the importance of studying the mechanisms older adults use to successfully cope with pain.

The etiology of chronic pelvic pain syndromes remains unknown. In a murine urinary tract infection (UTI) model, lipopolysaccharide of uropathogenic E. coli and its receptor TLR4 are required for post-UTI chronic pain development. However, downstream mechanisms of post-UTI chronic pelvic pain remain unclear. Because the TRPV1 and MCP-1/CCR2 pathways are implicated in chronic neuropathic pain, we explored their role in post-UTI chronic pain. Mice were infected with the E. coli strain SΦ874, known to produce chronic allodynia, and treated with the TRPV1 antagonist capsazepine. Mice treated with capsazepine at the time of SΦ874 infection failed to develop chronic allodynia, whereas capsazepine treatment of mice at two weeks following SΦ874 infection did not reduce chronic allodynia. TRPV1-deficient mice did not develop chronic allodynia either. Similar results were found using novelty-suppressed feeding (NSF) to assess depressive behavior associated with neuropathic pain. Imaging of reporter mice also revealed induction of MCP-1 and CCR2 expression in sacral dorsal root ganglia following SΦ874 infection. Treatment with a CCR2 receptor antagonist at two weeks post-infection reduced chronic allodynia. Taken together, these results suggest that TRPV1 has a role in the establishment of post-UTI chronic pain, and CCR2 has a role in maintenance of post-UTI chronic pain.

The prevalence of chronic non-malignant pain in Norway is between 24% and 30%. The proportion of the population using opioids for non-malignant pain on a long-term basis is around 1%. The purpose of our study was to investigate how many were prescribed analgesics on reimbursable prescription under reimbursement code -71 (chronic non-malignant pain) in 2009 and 2010, which analgesics were prescribed and whether prescribing practices were in accordance with national guidelines. We retrieved pseudonymised data from the National Prescription Database on all those who received drugs with reimbursement code -71 in 2009 and 2010. The data contain information on drug, dosage, formulation, reimbursement code and date of issue. 90,731 patients received reimbursement for drugs indicated for chronic non-malignant pain in 2010. Of these, 6,875 were given opioids, 33,242 received paracetamol, 25,865 non-steroid inflammatory drugs (NSAIDs), 20,654 amitryptiline and 16,507 gabapentin. Oxycodone was the most frequently prescribed opioid, followed by buprenorphine, tramadol and codeine/paracetamol. Of those who were prescribed opioids, 4,047 (59%) received mainly slow-release opioids, 2,631 (38%) also received benzodiazepines and 2,418 (35%) received benzodiazepine-like sleep medications. The number of patients who received analgesics and opioids on reimbursable prescriptions was low compared to the proportion of the population with chronic pain and the proportion using opioids long-term. 38% of those reimbursed for opioids also used benzodiazepines, which is contrary to official Norwegian guidelines.

Chronic pain is common in children and adolescents and is often associated with severe functional disability and mood disorders. The pharmacological treatment of chronic pain in children and adolescents can be challenging, ineffective, and is mostly based on expert opinions and consensus. Ketamine, an N-methyl-D-aspartate receptor antagonist, has been used as an adjuvant for treatment of adult chronic pain and has been shown, in some instances, to improve pain and decrease opioid-requirement. We examined the effects of subanesthetic ketamine infusions on pain intensity and opioid use in children and adolescents with chronic pain syndromes treated in an outpatient setting. Longitudinal cohort study of consecutive pediatric patients treated with subanesthetic ketamine infusions in a tertiary outpatient center. Outcome measurements included self-reported pain scores (numeric rating scale) and morphine-equivalent intake. Over a 15-month period, 63 children and adolescents (median age 15, interquartile range 12-17 years) with chronic pain received 277 ketamine infusions. Intravenous administration of subanesthetic doses of ketamine to children and adolescents on an outpatient basis was safe and not associated with psychotropic effects or hemodynamic perturbations. Overall, ketamine significantly reduced pain intensity (p pain reduction in patients with complex regional pain syndrome (CRPS) than in patients with other chronic pain syndromes (p = 0.029). Ketamine-associated reductions in pain scores were the largest in postural orthostatic tachycardia syndrome (POTS) and trauma patients and the smallest in patients with chronic headache (p = 0.007). In 37% of infusions, patients had a greater than 20 % reduction in pain score. Conversely, ketamine infusions did not change overall morphine-equivalent intake (p = 0.3). These data suggest that subanesthetic ketamine infusion is feasible in an outpatient setting and may benefit children and adolescents 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.

Chronic prostatitis can cause pain and urinary symptoms, and can occur either with an active infection (chronic bacterial prostatitis [CBP]) or with only pain and no evidence of bacterial causation (chronic pelvic pain syndrome [CPPS]). Bacterial prostatitis is characterised by recurrent urinary tract infections or infection in the prostate with the same bacterial strain, which often results from urinary tract instrumentation. However, the cause and natural history of CPPS are unknown and not associated with active infection. We conducted a systematic overview and aimed to answer the following clinical questions: What are the effects of treatments for chronic bacterial prostatitis? What are the effects of treatments for chronic pelvic pain syndrome? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview). At this update, searching of electronic databases retrieved 131 studies. After deduplication and removal of conference abstracts, 67 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 51 studies and the further review of 16 full publications. Of the 16 full articles evaluated, three systematic reviews and one RCT were included at this update. We performed a GRADE evaluation for 14 PICO combinations. In this systematic overview, we categorised the efficacy for 12 interventions based on information relating to the effectiveness and safety of 5 alpha-reductase inhibitors, allopurinol, alpha-blockers, local injections of antimicrobial drugs, mepartricin, non-steroidal anti-inflammatory drugs (NSAIDs), oral antimicrobial drugs, pentosan polysulfate, quercetin, sitz baths, transurethral microwave thermotherapy (TUMT), and transurethral resection of the prostate (TURP).

Chronic pain often interferes with daily functioning, and may become a threat to an individual's sense of self. Despite the development of a recent theoretical account focussing upon the relationship between the presence of chronic pain and a person's self, research investigating this idea is limited. In the present study we aimed to (1) compare the strength of association between self- and pain schema in patients with chronic pain and healthy control subjects and (2) research whether the strength of association between self- and pain-schema is related to particular pain-related outcomes and individual differences of patients with chronic pain. Seventy-three patients with chronic pain (M(age) = 49.95; SD = 9.76) and 53 healthy volunteers (M(age) = 48.53; SD = 10.37) performed an Implicit Association Test (IAT) to assess the strength of association between pain- and self-schema. Patients with chronic pain also filled out self-report measures of pain severity, pain suffering, disability, depression, anxiety, acceptance, and helplessness. Results indicated that the pain- and self-schema were more strongly associated in patients with chronic pain than in healthy control subjects. Second, results indicated that, in patients with chronic pain, a stronger association between self- and pain-schema, as measured with the IAT, is related to a heightened level of pain severity, pain suffering, anxiety, and helplessness. Current findings give first support for the use of an IAT to investigate the strength of association between self- and pain-schema in patients with chronic pain and suggest that pain therapies may incorporate techniques that intervene on the level of self-pain enmeshment.

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. An evidence-based classification system for chronic SCD pain was constructed for the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy initiative. Applying this taxonomy may improve assessment and management of SCD pain and accelerate research on epidemiology, mechanisms, and treatments for chronic SCD pain. Copyright © 2017 The Authors.

Over the past two decades, there has been a significant increase in the prescribing of opioids, with associated increases in opioid addiction and overdose deaths. This article reviews the evidence for the effectiveness and risk of developing an opioid use disorder (OUD) in those patients treated with chronic opioid therapy (COT) for chronic non-cancer pain (CNCP). Rates of development of OUD range from 0-50 %, and aberrant drug related behaviors (ADRBs) are reported to be 20 %. Health care providers must properly assess, screen, and carefully monitor patients on COT utilizing evidence-based tools.
Full Text Available Both chronic pain and obesity are known to affect reproductive hormone profiles in male patients. However, the effect of these conditions, alone or in combination, on male fertility potential has received less attention. 20 chronic musculoskeletal pain patients and 20 healthy controls were divided into lean and overweight subgroups according to their BMI. Current level of chronic pain (visual analogue scale and pressure pain thresholds (PPTs in 16 predefined sites, classically described and tested as painful points on the lower body, were measured. Levels of reproductive hormone and lipid profiles were assessed by ELISA. Sperm concentration and motility parameters were analyzed using a computer-aided sperm analysis system. Sperm concentration, progressive motility, and percentage of hyperactivated sperm were generally lower in the chronic pain patients in both lean and overweight groups. The overweight control and the lean chronic pain groups demonstrated a significantly lower percentage of progressively motile sperm compared with the lean control group, suggesting that musculoskeletal chronic pain may have a negative influence on sperm quality in lean patients. However, due to the potential great negative influence of obesity on the sperm parameters, it is difficult to propose if musculoskeletal chronic pain also influenced sperm quality in overweight patients. Further research in chronic pain patients is required to test this hypothesis.

We examined stereotyping of chronic pain sufferers among women aged 18-40 years and determined whether perceived stereotyping affects seeking care for women with chronic vulvar pain. Cross-sectional study using a community-based survey of vulvodynia asking if "Doctors think that people with chronic pain exaggerate their pain," and if "People believe that vulvar pain is used as an excuse to avoid having sex". Twelve thousand eight hundred thirty-four women aged 18-40 years in metropolitan Minneapolis/St. Paul, Minnesota. Women were considered to have a history of chronic vulvar pain if they reported vulvar burning lasting more than 3 months or vulvar pain on contact. Four thousand nine hundred eighty-seven (38.9%) women reported a chronic pain condition; 1,651 had chronic vulvar pain. Women experiencing chronic pain were more likely than those without to perceive stereotyping from both doctors and others; a dose-response with the number of pain conditions existed. Women with chronic vulvar pain were more likely to believe that people think vulvar pain is an excuse to avoid intercourse. Half of the women with chronic vulvar pain did not seek medical care for it; of these, 40.4% perceived stereotyping from doctors. However, it was women who actually sought care (45.1%) who were more likely to feel stigmatized by doctors (adjusted relative risk = 1.11, 95% confidence interval: 1.01-1.23). Perceived negative stereotyping among chronic pain sufferers is common, particularly negative perceptions about physicians. In fact, chronic vulvar pain sufferers who felt stigmatized were more likely to have sought care than those who did not feel stigmatized. Wiley Periodicals, Inc.

Chronic pain is an important public health issue. However, characteristics and needs of marginalized populations have received limited attention. Studies on prevalence and correlates of chronic pain among homeless persons are lacking. We assessed chronic pain among homeless persons with mental illness in the At Home/Chez Soi study. Cross-sectional data from a randomized controlled trial on homelessness and mental health. Data collected between 2009 and 2013 in three Canadian cities. One thousand two hundred eighty-seven homeless persons with mental illness. Data on chronic pain and utilization of prescribed and nonprescribed interventions was assessed using a chronic pain screening instrument. Mental illness was diagnosed with the Mini-International Neuropsychiatric Interview. Forty-three percent reported moderate to severe chronic pain, interfering with general daily activities (80%), sleep (78%), and social interactions (61%). Multivariate analysis indicated that increasing age and diagnoses of major depressive disorder, mood disorder with psychotic features, panic disorder, and post-traumatic stress disorder (PTSD) were independent predictors of chronic pain. Chronic pain was further associated with increased suicidality. Among participants reporting chronic pain, 64% had sought medical treatment and 56% treated pain with prescribed drugs, while 38% used illicit drugs for pain relief. Chronic pain is very common among homeless persons with mental illness and affects activities of daily living. Clinicians treating this population should be aware of the common connections between chronic pain, depression, panic disorder, PTSD, and substance use. While the data indicate the contribution of chronic pain to complex treatment needs, they also indicate a clear treatment gap. © 2017 American Academy of Pain Medicine. All rights reserved.

The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD). A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11). A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p craniomandibular pain and disability (p Neck disability was a significant covariate (37 % of variance) of craniomandibular pain and disability for the MP group (β = 0.62; p neck disability (β = 0.40; p craniomandibular pain and disability.

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.

The aim of this qualitative study was to explore participants' perspectives on the effects of chronic pain on the psychophysical unity. Thirty-four chronic pain outpatients were interviewed, and the transcribed interviews were analysed with Giorgi's four-phase phenomenological method. The mean age of the participants was 48 years, and 19 of them were women. For 21 of the participants, the pain duration was more than 5 years, and most had degenerative spinal pain. The results of this whole research project indicated that the phenomenon chronic pain consisted of four essential themes: Pain affects the whole person, invisibility, negativity, and dominance of pain. This study concentrates only on one theme "Chronic pain affects the whole person", in which were found eight subthemes in the interviews. The strongest argument made by the participants was not the physical pain itself but the psychosocial consequences, such as distress, loneliness, lost identity, and low quality of life which were their main problems. In multidisciplinary holistic rehabilitation, it is essential to take care of the patient's psychological distress. A potential source of psychosocial symptoms may be the subjective responses to experience of chronic pain due to the subjective meanings of pain. Implications for Rehabilitation About chronic pain Pain is an experience, not only an aversive sensation. Intensity of pain describes only the sensation, not the experience of pain. In chronic pain, the main complaint may be not the physical pain, but the distress. In rehabilitation, the patient needs to be taken as a whole person. Multidisciplinary rehabilitation, including patient counselling should be the fundamental part of treatment. In rehabilitation, the individual meaning of chronic pain needs to be disclosed.

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 unders...
Full Text Available Abstract Background Due to tolerance development and adverse side effects, chronic pain patients frequently need to be switched to alternative opioid therapy Objective To assess the efficacy and tolerability of an alternative transdermally applied (TDS opioid in patients with chronic cancer pain receiving insufficient analgesia using their present treatment. 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. Further studies are required to provide individualized treatment for patients according to their different types of cancer.

Overgenerality and delay of the retrieval of autobiographical memory (AM) are well documented in a range of clinical conditions, particularly in patients with emotional disorder. The present study extended the investigation to chronic pain, attempting to identify whether the retrieval of AM in patients with chronic pain tends to be overgeneral or delayed. With an observational cross-sectional design, we evaluated the AM both in patients with chronic pain and healthy controls by Autobiographical Memory Test. Pain conditions were assessed using the pain diagnostic protocol, the short-form McGill Pain Questionnaire (SF-MPQ), and the Pain Self-Efficacy Questionnaire (PSEQ). Emotion was assessed using the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory. Subjects included 176 outpatients with chronic pain lasting for at least 6 months and 170 healthy controls. 1) Compared with the healthy group, the chronic pain group had more overgeneral memories (OGMs) (F = 29.061, P OGM were significant (P OGM scores could be predicted by the BDI score (9.7%), pain chronicity (4.3%), PSEQ score (7.1%), and Affective Index (of SF-MPQ) score (2.7%). 3) In the chronic pain group, the stepwise multiple regression models for variables predicting latency were significant (P < 0.05). Specifically, the variance in latency could be predicted by age (3.1%), pain chronicity (2.7%), pain duration (4.3%), and PSEQ score (2.0%). The retrieval of AM in patients with chronic pain tends to be overgeneral and delayed, and the retrieval style of AM may be contributed to negative emotions and chronic pain conditions.

Although chronic pain in childhood can last into adulthood, few studies have evaluated the characteristics of adults with chronic pain who report childhood chronic pain. Thus, 1,045 new patients (mean age, 49.5 ± 15.4) at an academic tertiary care pain clinic were prospectively evaluated using validated self-report questionnaires. Patients also responded to questions about childhood pain. We found that almost 17% (n = 176) of adult chronic pain patients reported a history of chronic pain in childhood or adolescence, with close to 80% indicating that the pain in childhood continues today. Adults reporting childhood chronic pain were predominantly female (68%), commonly reported widespread pain (85%), and had almost 3 times the odds of meeting survey criteria for fibromyalgia (odds ratio [OR] = 2.94, 95% confidence interval [CI] = 2.04-4.23) than those denying childhood chronic pain. Similarly, those with childhood pain had twice the odds of having biological relatives with chronic pain (OR = 2.03, 95% CI = 1.39-2.96) and almost 3 times the odds of having relatives with psychiatric illness (OR = 2.85, 95% CI = 1.97-4.11). Lastly, compared to patients who did not report childhood chronic pain, those who did were more likely to use neuropathic descriptors for their pain (OR = 1.82, 95% CI = 1.26-2.64), have slightly worse functional status (B = -2.12, t = -3.10, P = .002), and have increased anxiety (OR = 1.77, 95% CI = 1.24-2.52). Our study revealed that 1 in 6 adult pain patients reported pain that dated back to childhood or adolescence. In such patients, evidence suggested that their pain was more likely to be widespread, neuropathic in nature, and accompanied by psychological comorbidities and decreased functional status.

The purpose of this paper is to investigate the clinical role of Magnetic Resonance Arthrography (MRA) of the wrist in subjects with chronic pain. Thirty-five patients complaining of wrist pain for more than 6 months were submitted to MRI an MRA. All patients received and intra-articular injection of 2-10 mL of a 10 mmol saline solution of Gd-DPTA. The overall diagnostic accuracy rates of MRI and MRA were 40% and 81% respectively, with sensitivity and specificity of 63% and 39% (MRI) and of 82% and 79% (MRA). The conclusion is that compared with MRI, MRA can be considered a useful tool for the visualization of interosseus carpal ligaments and of the triangular fibrocartilage complex. MRA also helps detect injuries in these structures [it

The majority of the reviews and studies on chronic pain in pregnancy have primarily focused on the pharmacological and non-pharmacological treatment options. The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery. A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included "chronic pain" AND "pregnant OR pregnancy" OR "pregnancy complications" from inception through August 2016. The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1) complete history and physical examination; 2) monitor patients for alcohol, nicotine, and substance use; 3) collaborate with patient to set treatment goals; 4) develop a management plan; 5) for opioids, use lowest effective dose; 6) formulate a pain management plan for labor and delivery; and 7) discuss reproductive health with women with chronic pain. The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available.

Chronic scrotal content pain (CSCP) is a common condition that can be challenging to manage definitively. A cohort of patients with CSCP have referred pain from myofascial abnormalities of the pelvic floor and therefore require treatment modalities that specifically address the pelvic floor such as pelvic floor physical therapy (PFPT). Retrospective chart review of all men with a pelvic floor component of CSCP presenting to our tertiary care medical center and undergoing PFPT from 2011-2014. Patients with CSCP and pain/tightness on pelvic floor evaluation with 360° digital rectal exam (DRE) were referred to a physiotherapist for PFPT. CSCP was defined as primary unilateral or bilateral pain of the testicle, epididymis and/or spermatic cord that was constant or intermittent, lasted greater than 3 months, and significantly interfered with daily activities. Long term follow up was conducted by office visit and physical therapy chart review. Thirty patients, mean age of 42 years (range 18-75), were followed for a median of 13 months (range 3-48). Median pre-PFPT pain score was 6/10 (range 2-10). After a mean of 12 PFPT sessions (IQR 6-16), pain improved in 50.0% of patients, median decrease in pain was 4.5/10 (range 1-10). Complete resolution of pain occurred in 13.3%, 44.0% had none to minor residual pain. Following PFPT, fewer subjects required pain medication compared with prior to PFPT (44.0% versus 73.3%, p = 0.03). For men with CSCP and a positive pelvic floor exam with DRE, we recommend a trial of PFPT as an effective and non-operative treatment modality.

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.

The treatment of chronic pain could benefit from additional non-opioid interventions. Virtual reality (VR) has been shown to be effective in decreasing pain for procedural or acute pain but to date there have been few studies on its use in chronic pain. The present study was an investigation of the impact of a virtual reality application for chronic pain. Thirty (30) participants with various chronic pain conditions were offered a five-minute session using a virtual reality application called Cool! Participants were asked about their pain using a 0-10 visual analog scale rating before the VR session, during the session and immediately after the session. They were also asked about immersion into the VR world and about possible side effects. Pain was reduced from pre-session to post-session by 33%. Pain was reduced from pre-session during the VR session by 60%. These changes were both statistically significant at the p virtual reality session. All participants (100%) reported a decrease in pain to some degree between pre-session pain and during-session pain. The virtual reality experience was found here to provide a significant amount of pain relief. A head mounted display (HMD) was used with all subjects and no discomfort was experienced. Only one participant noted any side effects. VR seems to have promise as a non-opioid treatment for chronic pain and further investigation is warranted.

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 implementati...
Full Text Available BACKGROUND: Chronic neuropathic pain (CNP in spinal cord injury (SCI is recognized as severely compromising, in both adjustment after injury and quality of life. Studies indicate that chronic pain in SCI is associated with great emotional distress over and above that of the injury itself. Currently, little is known about the SCI patient's perception of the impact of living with chronic neuropathic pain.

We examined the association of chronic musculoskeletal pain with executive function in community-dwelling older adults. This cross-sectional study recruited 234 community-dwelling older adults in Japan (mean age: 72.7, women: 62.8%). Chronic musculoskeletal pain was defined as having moderate or more severe pain lasting ≥ 3 months. Executive function was assessed using the Digit Symbol Substitution Test (DSST), Trail Making Test (TMT) parts A and B, Letter Verbal Fluency Test (LVFT) and Category Verbal Fluency Test (CVFT). Prevalence of chronic musculoskeletal pain was 19% (n = 44). In the univariate analysis, the DSST and CVFT scores were significantly lower in the chronic musculoskeletal pain group than in the control group (DSST: chronic musculoskeletal pain group vs. control group, 40.2 vs. 45.4, respectively, p dwelling older adults. The association of chronic musculoskeletal pain with executive function requires further investigation. Our results suggest an association between moderate-severe chronic musculoskeletal pain and impairments of semantic fluency and processing speed in community-dwelling older adults. © 2017 European Pain Federation - EFIC®.

Chronic pelvic pain is an increasingly common complaint among women, particularly in the reproductive age group. Multiple factors contribute to causation and aggravation of such pain. It affects the social life of the female. The study evaluated demographic and historic variables in women with chronic pelvic pain, differentiated organic from functional causes by non-invasive available measures and evaluated the effectiveness of commonly used treatment options in treatment of chronic pelvic pain. The study was conducted on 160 cases of chronic pelvic pain, attending gynaecology OPD of UP RIMS&R, Etawah. They were evaluated with respect to age, parity, socio-economic status, pattern of pain, associated symptoms, pelvic examination and subsequent management outcome. Specific management was done for organic cause, while analgesics and tranquilisers were prescribed for functional pain. It was found most commonly in 31-35 years age group women, in which 62% were multipara and 74% belonged to the lower socio-economic status (classes IV and V). Specific pathological diagnosis was done only in 56.25% cases. Chronic constant lower abdominal pain was the most common (64%) presentation. Only 65% of patients showed improvement with the medical treatment. Chronic pelvic pain is quite common complaint in rural western Uttar Pradesh. It requires more specific diagnostic aids and treatment protocols for functional pain. Therapeutic success can be achieved by regular supportive doctor-patient interaction.

Chronic pain may disable the body, depress the mind and ruin the quality of life. The aim of this study was to use the participants' personal experiences to explore the meaning of the experience of chronic pain and to find successful ways to manage chronic pain. Thirty-four participants with chronic pain were interviewed. The transcribed interviews were analysed using Giorgi's phenomenological method consisting of four phases: (1) reading the transcriptions several times, (2) discriminating meaning units, (3) collecting meaning units into groups and (4) the synthesis. The participants stated that the key to managing chronic pain was to reconsider the individual meaning of the experience of pain. As a result of the interviews, seven subthemes were found based on the 'Negativity of chronic pain', namely, 'State of reflection', 'Reconsidering values', 'Acceptance of pain', 'Support network', 'Altered self', 'Joys in life' and 'Pain dissociation'. Pain is an aversive sensation, which leads to the conclusion that the meaning of the experience is also negative, but it can be reversed. In clinical practice, the focus should be on revising the subjective meaning of pain in order to manage pain and to restore positivity in personal life. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Lumbopelvic stabilization training (LPST) may provide therapeutic benefits on pain modulation in chronic nonspecific low back pain conditions. This study aimed to examine the effects of LPST on pain threshold and pain intensity in comparison with the passive automated cycling intervention and control intervention among patients with chronic nonspecific low back pain. A within-subject, repeated-measures, crossover randomized controlled design was conducted among 25 participants (7 males and 18 females) with chronic nonspecific low back pain. All the participants received 3 different types of experimental interventions, which included LPST, the passive automated cycling intervention, and the control intervention randomly, with 48 hours between the sessions. The pressure pain threshold (PPT), hot-cold pain threshold, and pain intensity were estimated before and after the interventions. Repeated-measures analysis of variance showed that LPST provided therapeutic effects as it improved the PPT beyond the placebo and control interventions (P pain intensity under the LPST condition was significantly better than that under the passive automated cycling intervention and controlled intervention (P pain threshold under the LPST condition also showed a significant trend of improvement beyond the control (P pain threshold were evident. Lumbopelvic stabilization training may provide therapeutic effects by inducing pain modulation through an improvement in the pain threshold and reduction in pain intensity. LPST may be considered as part of the management programs for treatment of chronic low back pain. © 2017 World Institute of Pain.

Objectives Questionnaire-based research has shown that parents exert a powerful influence on and are profoundly influenced by living with a child with chronic pain. Examination of parents' pain narratives through an observational lens offers an alternative approach to understanding the complexity of pediatric chronic pain; however, the narratives of parents of youth with chronic pain have been largely overlooked. The present study aimed to characterize the vulnerability- and resilience-based aspects of the pain narratives of parents of youth with chronic pain. Methods Pain narratives of 46 parents were recorded during the baseline session as part of two clinical trials evaluating a behavioral intervention for parents of youth with chronic pain. The narratives were coded for aspects of pain-related vulnerability and resilience. Results Using exploratory cluster analysis, two styles of parents’ pain narratives were identified. Distress narratives were characterized by more negative affect and an exclusively unresolved orientation towards the child’s diagnosis of chronic pain whereas resilience narratives were characterized by positive affect and a predominantly resolved orientation towards the child’s diagnosis. Preliminary support for the validity of these clusters was provided through our finding of differences between clusters in parental pain catastrophizing about child pain (helplessness). Discussion Findings highlight the multidimensional nature of parents’ experience of their child’s pain problem. Clinical implications in terms of assessment and treatment are discussed. PMID:26736026

This is an experimental study of pain communication in couples. Despite evidence that chronic pain in one partner impacts both members of the dyad, dyadic influences on pain communication have not been sufficiently examined and are typically studied based on retrospective reports. Our goal was to directly study contextual influences (ie, presence of chronic pain, gender, relationship quality, and pain catastrophizing) on self-reported and nonverbal (ie, facial expressions) pain responses. Couples with (n = 66) and without (n = 65) an individual with chronic pain (ICP) completed relationship and pain catastrophizing questionnaires. Subsequently, one partner underwent a pain task (pain target, PT), while the other partner observed (pain observer, PO). In couples with an ICP, the ICP was assigned to be the PT. Pain intensity and PO perceived pain intensity ratings were recorded at multiple intervals. Facial expressions were video recorded throughout the pain task. Pain-related facial expression was quantified using the Facial Action Coding System. The most consistent predictor of either partner's pain-related facial expression was the pain-related facial expression of the other partner. Pain targets provided higher pain ratings than POs and female PTs reported and showed more pain, regardless of chronic pain status. Gender and the interaction between gender and relationship satisfaction were predictors of pain-related facial expression among PTs, but not POs. None of the examined variables predicted self-reported pain. Results suggest that contextual variables influence pain communication in couples, with distinct influences for PTs and POs. Moreover, self-report and nonverbal responses are not displayed in a parallel manner.
Full Text Available Chronic pelvic pain (CPP is a disabling disease that causes distress as the quality of life of CPP patients is vastly diminished. In addition, CPP is a public health crisis and is a burden on healthcare expenditure. In the United States, the annual costs for the diagnosis and treatment of CPP are 2.8 billion US $. Moreover, to the indirect cost resulting from the absence from work and CPP associated family problems add 550 million US $ more making the economic burden more than 3.4 billion US $ (Mathias et al., 1996. Yet, the diagnosis of CPP is usually complicated as there are no gold standard guidelines that clearly define this syndrome. Although we have a limited understanding of its etiology, CPP has been found to be correlated with central sensitization, painful bladder syndrome, irritable bowel syndrome, endometriosis and adhesions. As such, in the evaluation of patients, it is imperative to take a comprehensive patient history. Performing physical examinations and ultrasound imaging is of particular value to elucidate the etiology of pain. As CPP patients are at risk for psychological disorders, psychological assessments are critical to diagnose associated psychological disorders and to take these into account in planning a holistic treatment plan for patients. By such evaluation techniques, we can provide better diagnostic service and patient care to people with CPP.

Results: We found that after 2...
Full Text Available Introduction. Estimates on the epidemiology of chronic pain vary widely throughout Europe. It is unclear whether this variation reflects true differences between populations or methodological factors. Information on the epidemiology of chronic pain can support decision makers in allocating adequate health care resources. Methods. In order to obtain epidemiological data on chronic pain in Denmark and Sweden, we conducted a literature review of epidemiological data primarily on chronic noncancer pain, prioritising studies of highest quality, recency, and validity by conducting a systematic search for relevant studies. Following quality assessment, data were summarised and assigned to the research questions. Results. The prevalence of moderate to severe noncancer pain was estimated at 16% in Denmark and 18% in Sweden. Chronic pain impacts negatively on perceived health status, quality of life and is associated with increased cost. Despite using pain medications, a large proportion of chronic pain sufferers have inadequate pain control. There was a lack of high-quality and low-bias studies with clear inclusion criteria. Conclusions. In both Denmark and Sweden, chronic pain is a common health problem which is potentially undertreated and warrants attention of health care workers, policy makers and researchers. Future research should utilise clear reporting guidelines to assist decision and policy makers, in this important area.

The population prevalence of pediatric chronic pain is not well characterized, in part due to lack of nationally representative data. Previous research suggests that pediatric chronic pain prolongs inpatient stay and increases costs, but the population-level association between pediatric chronic pain and health care utilization is unclear. We use the 2016 National Survey of Children's Health to describe the prevalence of pediatric chronic pain, and compare health care utilization among children ages 0-17 years according to the presence of chronic pain. Using a sample of 43,712 children, we estimate the population prevalence of chronic pain to be 6%. On multivariable analysis, chronic pain was not associated with increased odds of primary care or mental health care use, but was associated with greater odds of using other specialty care (OR=2.01, 95% CI: 1.62, 2.47; pcomplementary and alternative medicine (OR=2.32, 95% CI: 1.79, 3.03; pchronic pain were more likely to use specialty care but not mental health care. The higher likelihood of emergency care use in this group raises the question of whether better management of pediatric chronic pain could reduce emergency department use. Copyright © 2018.

The prevalence of temporomandibular disorders in patients with chronic whiplash-associated disorder is a controversial issue that may be influenced by the widespread pain character and psychologic distress frequently observed in patients with chronic pain. The aim of this study was to determine the prevalence of temporomandibular disorder pain, widespread pain, and psychologic distress in persons with chronic whiplash-associated disorder pain, using a controlled, single blind study design. The prevalence of temporomandibular disorder pain in the chronic whiplash-associated disorder pain group was compared with 2 control groups: a chronic neck pain group and a no neck pain group. From 65 persons, a standardized oral history was taken, a physical examination of the neck and the masticatory system was performed, widespread pain was investigated by tender point palpation, and psychologic distress was measured with a questionnaire (SCL-90). Because the recognition of temporomandibular disorder pain and neck pain remains a matter of debate, 3 well-defined classification systems were used: one based on the oral history, a second on a combination of oral history and pain on active movements and palpation, and a third one based on a combination of oral history and function tests. Irrespective of the classification system used, the chronic whiplash-associated disorder pain group more often suffered from temporomandibular disorder pain (0.001neck pain group. Moreover, patients with whiplash-associated disorder showed more psychologic distress (0.000disorder suggests that the higher prevalence of temporomandibular disorder pain in these patients is part of a more widespread chronic pain disorder.

Our goal in this study was to review the similarities and differences among ethnic groups and their respective responses to acute and chronic clinically related and experimentally induced pain. In this review, the PUBMED and Google-Scholar databases were searched to analyze articles that have assessed the variations in both acute and chronic pain responses among different ethnic/racial groups. According to the results from 42 reviewed articles, significant differences exist among ethnic-racial groups for pain prevalence as well as responses to acute and chronic pain. Compared with Caucasians, other ethnic groups are more susceptible to acute pain responses to nociceptive stimulation and to the development of long-term chronic pain. These differences need to be addressed and assessed more extensively in the future in order to minimize the pain management disparities among various ethnic-racial groups and also to improve the relationship between pain management providers and their patients.

The World Health Organization has predicted that arthritis will rise to become the fourth ranked global disability among the elderly. Arthritis is already a main cause of chronic pain, depression, and institutionalization in this group. Chronic pain resulting from arthritis is a serious threat to the elderly population. Study purposes were to: (1) explore chronic pain in elderly residents with arthritis residing at long-term care facilities and to understand the relationship between associated chronic pain and associated factors, and (2) identify the predictive factors of chronic pain. This study used a cross-sectional, descriptive correlational research design. A sample of 114 elderly residents, 65 years of age and older, were recruited from five long-term care facilities in Kaohsiung and Pingtung, Taiwan. Findings showed that the average pain intensity resulting from chronic arthritis during the three months of study was medium (4.51 ± 1.75). There were positive relationships amongst average pain intensity, previous pain intensity, self-perception of arthritis severity and depression status. Negative correlations were found amongst age, self-perception of arthritis severity, number of chronic illnesses experienced, function of daily activity and social support. Previous pain intensity, self-perception of arthritis severity, number of chronic illnesses experienced, function of daily activity and depression status were all found to predict chronic pain. Together, these factors explained 40.4% of total variance. Study results provide information for nurses to consider the physical, psychological, and social aspects of chronic pain when caring for the elderly. Healthcare providers should design individualized health care interventions for elderly people to promote their quality of life.

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.
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.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition that causes severe symptoms, bother, and quality-of-life impact in the 8.2% of men who are believed to be affected. Research suggests a complex pathophysiology underlying this syndrome that is mirrored by its heterogeneous clinical presentation. Management of patients diagnosed with CP/CPPS has always been a formidable task in clinical practice. Due to its enigmatic etiology, a plethora of clinical trials failed to identify an efficient monotherapy. A comprehensive review of published randomized controlled trials (RCTs) on the treatment of CP/CPPS and practical best evidence recommendations for management. Medline and the Cochrane database were screened for RCTs on the treatment of CP/CPPS from 1998 to December 2014, using the National Institutes of Health Chronic Prostatitis Symptom Index as an objective outcome measure. Published data in concert with expert opinion were used to formulate a practical best evidence statement for the management of CP/CPPS. Twenty-eight RCTs identified were eligible for this review and presented. Trials evaluating antibiotics, α-blockers, anti-inflammatory and immune-modulating substances, hormonal agents, phytotherapeutics, neuromodulatory drugs, agents that modify bladder function, and physical treatment options failed to reveal a clear therapeutic benefit. With its multifactorial pathophysiology and its various clinical presentations, the management of CP/CPPS demands a phenotypic-directed approach addressing the individual clinical profile of each patient. Different categorization algorithms have been proposed. First studies applying the UPOINTs classification system provided promising results. Introducing three index patients with CP/CPPS, we present practical best evidence recommendations for management. Our current understanding of the pathophysiology underlying CP/CPPS resulting in this highly variable syndrome does not speak in favor of a

Many dysfunctional and chronic pain conditions overlap. This review describes the different modes of chronic deregulation of the adaptive response to stress which may be a common factor for these conditions. Several types of dysfunction can be identified within the hypothalamo-pituitary-adrenal axis: basal hypercortisolism, hyper-reactivity, basal hypocortisolism and hypo-reactivity. Neuroactive steroid synthesis is another component of the adaptive response to stress. Dehydroepiandrosterone (DHEA) and its sulfated form DHEA-S, and progesterone and its derivatives are synthetized in cutaneous, nervous, and adipose cells. They are neuroactive factors that act locally. They may have a role in the localization of the symptoms and their levels can vary both in the central nervous system and in the periphery. Persistent changes in neuroactive steroid levels or precursors can induce localized neurodegeneration. The autonomic nervous system is another component of the stress response. Its dysfunction in chronic stress responses can be expressed by decreased basal parasympathethic activity, increased basal sympathetic activity or sympathetic hyporeactivity to a stressful stimulus. The immune and genetic systems also participate. The helper-T cells Th1 secrete pro-inflammatory cytokines such as IL-1-β, IL-2, IL-6, IL-8, IL-12, IFN-γ, and TNF-α, whereas Th2 secrete anti-inflammatory cytokines: IL-4, IL-10, IGF-10, IL-13. Chronic deregulation of the Th1/Th2 balance can occur in favor of anti- or pro-inflammatory direction, locally or systemically. Individual vulnerability to stress can be due to environmental factors but can also be genetically influenced. Genetic polymorphisms and epigenetics are the main keys to understanding the influence of genetics on the response of individuals to constraints. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine the prevalence of comorbid chronic pain among patients with opioid use disorder (OUD) and to compare other comorbidities (substance use disorder (SUD), mental health disorders, health/disease conditions) among patients in four categories: no chronic pain (No Pain), OUD prior to pain (OUD First), OUD and pain at the same time (Same Time), or pain condition prior to OUD (Pain First). Using an electronic health record (EHR) database from 2006-2015, the study assessed 5307 adult patients with OUD in a large healthcare system; 35.6% were No Pain, 9.7% were OUD First, 14.9% were Same Time, and 39.8% were Pain First. Most OUD patients (64.4%) had chronic pain conditions, and among them 61.8% had chronic pain before their first OUD diagnosis. Other SUDs occurred more frequently among OUD First patients than among other groups in terms of alcohol (33.4% vs. 25.4% for No Pain, 20.7% for Same Time, and 20.3% for Pain First), cocaine (19.0%, vs. 13.8%, 9.4%, 7.1%), and alcohol or drug-induced disorders. OUD First patients also had the highest rates of HIV (4.7%) and hepatitis C virus (HCV; 28.2%) among the four groups. Pain First patients had the highest rates of mental disorder (81.7%), heart disease (72.0%), respiratory disease (68.4%), sleep disorder (41.8%), cancer (23.4%), and diabetes (19.3%). The alarming high rates of chronic pain conditions occurring before OUD and the associated severe mental health and physical health conditions require better models of assessment and coordinated care plans to address these complex medical conditions.

Patients with chronic low back pain often report that they do not perceive their painful back accurately. Previous studies confirmed that sensory dissociation and/or discrepancy between perceived body image and actual size is one of the specific traits of patients with chronic pain. Current approaches for measuring sensory dissociation are limited to two-point-discrimination or rely on pain drawings not allowing for quantitative analysis. This case study reports the sensory dissociation of two cases with chronic low back pain using a recently published test (point-to-point-test (PTP)) and a newly developed test (two-point-estimation (TPE)). Both patients mislocalized tactile stimuli delivered to the painful location compared to non-painful locations (PTP test). In addition, both patients perceived their painful lumbar region differently from non-painful sites above and below and contralateral to the painful site. TPE data showed two distinct clinical patterns of sensory dissociation: one patient perceived the two-point distance in the painful area as expanded, while the other patient perceived it as shrunk. The latter pattern of sensory dissociation (i.e., pattern shrunk) is likely to respond to sensory training. Whether enlarged patterns of sensory dissociation are more resistant to treatment remains unknown but would explain the low effectiveness of previous studies using sensory training in chronic low back pain populations. Subgrouping patients according to their sensory discrimination pattern could contribute to the choice and effectiveness of the treatment approach.

Chronic neck pain is one of the most usual neuromusculoskeletal pain conditions which can lead patients to chronic disability. Similarly to other pain conditions, the changed psychological status of these patients is believed to be associated with their pain condition and disability. However, the association between the psychological status of patients with idiopathic neck pain and their pain intensity and disability is minimally explored. This study was aimed at investigating the association between psychological states (anxiety, depression, kinesiophobia, catastrophizing) of patients with chronic idiopathic neck pain and self-reported pain and disability. Forty five patients with idiopathic chronic neck pain (more than 6 months, at least once a week) participated. Their psychological states were assessed by using the Hospital Anxiety and Depression scale, Pain Catastrophizing scale and Tampa Scale for Kinesiophobia. Self-reported disability was recorded with the Neck Disability Index. Pain intensity was recorded by using a visual analog scale. Neck pain intensity was significantly correlated with anxiety (pneck pain is associated with their self-reported disability, whereas anxiety is also associated with their pain intensity. Anxiety and catastrophizing may be important predicting markers of patients' self-reported disability.

Patients with chronic pain syndromes, like fibromyalgia (FM) complain of widespread pain and tenderness, as well as non-refreshing sleep, cognitive dysfunction, and negative mood. Several lines of evidence implicate abnormalities of central pain processing as contributors for chronic pain, including dysfunctional descending pain inhibition. One form of endogenous pain inhibition, diffuse noxious inhibitory controls (DNIC), has been found to be abnormal in some chronic pain patients and eviden...

An important construct in understanding pain-related disability is pain-related fear. Heightened pain-related fear may result in behavioral avoidance leading to disuse, disability, and depression; whereas confrontation of avoided activities may result in a reduction of fear over time and reengagement with activities of daily living. Although there are several measures to assess pain-related fear among adults with chronic pain, none exist for children and adolescents. The aim of the current study was to develop a new tool to assess avoidance and fear of pain with pediatric chronic pain patients: the Fear of Pain Questionnaire, child report (FOPQ-C), and Fear of Pain Questionnaire, parent proxy report (FOPQ-P). After initial pilot testing, the FOPQ-C and FOPQ-P were administered to 299 youth with chronic pain and their parents at an initial multidisciplinary pain treatment evaluation. The FOPQ demonstrated very strong internal consistency of .92 for the child and parent versions. One-month stability estimates were acceptable and suggested responsivity to change. For construct validity, the FOPQ correlated with generalized anxiety, pain catastrophizing, and somatization. Evidence of criterion-related validity was found with significant associations for the FOPQ with pain, healthcare utilization, and functional disability. These results support the FOPQ as a psychometrically sound measure. Pain-related fear plays an important role in relation to emotional distress and pain-related disability among children and adolescents with chronic pain. Identification of patients with high levels of fear avoidance of pain with the FOPQ will inform how to proceed with psychological and physical therapy interventions for chronic pain.

Introduction Nonspecific chronic low back pain (NSCLBP), is the most common musculoskeletal cause of disability and has a major socio-economic impact on today’s western society1. The rehabilitation of chronic low back pain requires a multidisciplinary approach with both education and exercise therapy. Since physical deconditioning is often observed in patients with chronic low back pain, physical reconditioning is an important component of the exercise therapy during rehabilitation2. High ...

Despite ample research documenting deficits in executive functioning for adults with chronic pain, the literature on pediatric patients with chronic pain is limited and provides mixed results. The current study sought to further investigate the nature of executive dysfunction in this population and also examine the relationships between pain intensity, duration, and catastrophizing with sustained attention, working memory, and self- and parent-report of executive functioning. Pediatric pain clinic and rehabilitation program. Forty adolescents with chronic pain and their parents participated in this study. Participants completed neuropsychological measures and standardized self-report questionnaires during a 45- to 60-minute testing session. Fifty percent of this sample of adolescents with chronic pain demonstrated significant difficulties on at least one measure, with nine participants indicating difficulties on multiple measures. Pain significantly increased during the testing session. Pain variables of intensity, duration, and catastrophizing are related to sustained attention and working memory. This study adds support to previous findings suggesting subclinical struggles with executive functioning for adolescents with chronic pain. One-half of the sample indicated difficulties in either sustained attention and/or working memory. Future studies that would more thoroughly examine more complex executive functioning skills in this population would be helpful to further guide multidisciplinary treatment of these patients, particularly regarding whether or not school accommodations are warranted. © 2017 American Academy of Pain Medicine.

Low back pain (LBP) is the leading cause of disability worldwide. Of those patients who present to primary care with acute LBP, 40% continue to report symptoms 3 months later and develop chronic LBP. Although it is possible to identify these patients early, effective interventions to improve their outcomes are not available. This double-blind (participant/outcome assessor) randomised controlled trial will investigate the efficacy of a brief educational approach to prevent chronic LBP in 'at-risk' individuals. Participants will be recruited from primary care practices in the Sydney metropolitan area. To be eligible for inclusion participants will be aged 18-75 years, with acute LBP (education or 2×1 h sessions of sham education from a specially trained study physiotherapist. The study requires 101 participants per group to detect a 1-point difference in pain intensity 3 months after pain onset. Secondary outcomes include the incidence of chronic LBP, disability, pain intensity, depression, healthcare utilisation, pain attitudes and beliefs, global recovery and recurrence and are measured at 1 week post-intervention, and at 3, 6 and 12 months post LBP onset. Ethical approval was obtained from the University of New South Wales Human Ethics Committee in June 2013 (ref number HC12664). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conference meetings. https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12612001180808.

Cognitive and behavioral approach of chronic pain presents encouraging results by improving physical, functional and psychological states of chronic pain patients. This specific treatment is partially based on the acquisition of new adaptive strategies to help the patients to manage more effectively chronic pain and to improve subsequently their subjective well-being. This requires in parallel to give up noxious emotional, cognitive and behavioral attitudes towards pain. Now, we have to admit that numerous therapeutic failures are directly imputable to difficulties introducing and making the indispensable changes continue in pursuit of the fixed therapeutic objectives. Readiness to change could play a considerable role in the success or not of chronic pain treatment. The main objective of this article is to present the data of the current literature concerning the specificities of the process of change in the field of the chronic pain. We present a review of the literature describing at first, the psychological progress made by chronic pain patients longing to manage their suffering better via the trans-theoretical model of intentional change. Secondly, we develop the contributions of the technique of motivational interviewing in the improvement of chronic pain treatment. The identification of the motivational profile of chronic pain patients will determine how motivational interviewing can be conducted to improve their readiness for change. There are several strategies used with chronic pain patients in pre-contemplative and contemplative stages. Therapists may facilitate the problem recognition (help chronic pain patients to become aware of and identify the nature of the difficulties they face when trying to cope with their physical suffering); increase the personal concern (empowering chronic pain patients so that they feel fully involved in what they offer and invest in the therapy); develop the intention of change (ensure that the change becomes truly

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. Despite considerable variability in reported pain outcomes, pain catastrophizing was identified as a significant
Full Text Available Abstract Background Chikungunya virus (CHIKV is responsible for major epidemics worldwide. Autochthonous cases were recently reported in several European countries. Acute infection is thought to be monophasic. However reports on chronic pain related to CHIKV infection have been made. In particular, the fact that many of these patients do not respond well to usual analgesics suggests that the nature of chronic pain may be not only nociceptive but also neuropathic. Neuropathic pain syndromes require specific treatment and the identification of neuropathic characteristics (NC in a pain syndrome is a major step towards pain control. Methods We carried out a cross-sectional study at the end of the major two-wave outbreak lasting 17 months in Réunion Island. We assessed pain in 106 patients seeking general practitioners with confirmed infection with the CHIK virus, and evaluated its impact on quality of life (QoL. Results The mean intensity of pain on the visual-analogical scale (VAS was 5.8 ± 2.1, and its mean duration was 89 ± 2 days. Fifty-six patients fulfilled the definition of chronic pain. Pain had NC in 18.9% according to the DN4 questionnaire. Conversely, about two thirds (65% of patients with NC had chronic pain. The average pain intensity was similar between patients with or without NC (6.0 ± 1.7 vs 6.1 ± 2.0. However, the total score of the Short Form-McGill Pain Questionnaire (SF-MPQ(15.5 ± 5.2 vs 11.6 ± 5.2; p Conclusions There exists a specific chronic pain condition associated to CHIKV. Pain with NC seems to be associated with more aggressive clinical picture, more intense impact in QoL and more challenging pharmacological treatment.

Background In men with chronic prostatitis–chronic pelvic pain syndrome, treatment with alpha-adrenergic receptor blockers early in the course of the disorder has been reported to be effective in some, but not all, relatively small randomized trials. Methods We conducted a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of alfuzosin, an alpha-adrenergic receptor blocker, in reducing symptoms in men with chronic prostatitis–chronic pelvic pain syndrome. Participation in the study required diagnosis of the condition within the preceding 2 years and no previous treatment with an alpha-adrenergic receptor blocker. Men were randomly assigned to treatment for 12 weeks with either 10 mg of alfuzosin per day or placebo. The primary outcome was a reduction of at least 4 points (from baseline to 12 weeks) in the score on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (range, 0 to 43; higher scores indicate more severe symptoms). A 4-point decrease is the minimal clinically significant difference in the score. Results A total of 272 eligible participants underwent randomization, and in both study groups, 49.3% of participants had a decrease of at least 4 points in their total NIH-CPSI score (rate difference associated with alfuzosin, 0.1%; 95% confidence interval, −11.2 to 11.0; P = 0.99). In addition, a global response assessment showed similar response rates at 12 weeks: 33.6% in the placebo group and 34.8% in the alfuzosin group (P = 0.90). The rates of adverse events in the two groups were also similar. Conclusions Our findings do not support the use of alfuzosin to reduce the symptoms of chronic prostatitis–chronic pelvic pain syndrome in men who have not received prior treatment with an alpha-blocker.

Background Chronic pain is common in multimorbid patients. However, little is known about the implications of chronic pain and analgesic treatment on multimorbid patients. This study aimed to assess chronic pain therapy with regard to the interaction potential in a sample of inpatients with multiple chronic conditions. Methods and Findings We conducted a retrospective study with all multimorbid inpatients aged ≥18 years admitted to the Department of Internal Medicine of University Hospital Zurich in 2011 (n = 1,039 patients). Data were extracted from the electronic health records and reviewed. We identified 433 hospitalizations of patients with chronic pain and analyzed their combinations of chronic conditions (multimorbidity). We then classified all analgesic prescriptions according to the World Health Organization (WHO) analgesic ladder. Furthermore, we used a Swiss drug-drug interactions knowledge base to identify potential interactions between opioids and other drug classes, in particular coanalgesics and other concomitant drugs. Chronic pain was present in 38% of patients with multimorbidity. On average, patients with chronic pain were aged 65.7 years and had a mean number of 6.6 diagnoses. Hypertension was the most common chronic condition. Chronic back pain was the most common painful condition. Almost 90% of patients were exposed to polypharmacotherapy. Of the chronic pain patients, 71.1% received opioids for moderate to severe pain, 43.4% received coanalgesics. We identified 3,186 potential drug-drug interactions, with 17% classified between analgesics (without coanalgesics). Conclusions Analgesic drugs-related DDIs, in particular opioids, in multimorbid patients are often complex and difficult to assess by using DDI knowledge bases alone. Drug-multimorbidity interactions are not sufficiently investigated and understood. Today, the scientific literature is scarce for chronic pain in combination with multiple coexisting medical conditions and medication

Experiences and memories are often mismatched. While multiple studies have investigated psychological underpinnings of recall error with respect to emotional events, the neurobiological mechanisms underlying the divergence between experiences and memories remain relatively unexplored in the domain of chronic pain. Here we examined the discrepancy between experienced chronic low back pain (CBP) intensity (twice daily ratings) and remembered pain intensity (n = 48 subjects) relative to psychometric properties, hippocampus morphology, memory capabilities, and personality traits related to reward. 77% of CBP patients exaggerated remembered pain, which depended on their strongest experienced pain and their most recent mood rating. This bias persisted over nearly 1 year and was related to reward memory bias and loss aversion. Shape displacement of a specific region in the left posterior hippocampus mediated personality effects on pain memory bias, predicted pain memory bias in a validation CBP group (n = 21), and accounted for 55% of the variance of pain memory bias. In two independent groups (n = 20/group), morphology of this region was stable over time and unperturbed by the development of chronic pain. These results imply that a localized hippocampal circuit, and personality traits associated with reward processing, largely determine exaggeration of daily pain experiences in chronic pain patients.

Chronic cancer pain is a serious complication of malignancy or its treatment. Currently, no comprehensive, universally accepted cancer pain classification system exists. Clarity in classification of common cancer pain syndromes would improve clinical assessment and management. Moreover, an evidence-based taxonomy would enhance cancer pain research efforts by providing consistent diagnostic criteria, ensuring comparability across clinical trials. As part of a collaborative effort between the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) and the American Pain Society (APS), the ACTTION-APS Pain Taxonomy initiative worked to develop the characteristics of an optimal diagnostic system. After the establishment of these characteristics, a working group consisting of clinicians and clinical and basic scientists with expertise in cancer and cancer-related pain was convened to generate core diagnostic criteria for an illustrative sample of 3 chronic pain syndromes associated with cancer (ie, bone pain and pancreatic cancer pain as models of pain related to a tumor) or its treatment (ie, chemotherapy-induced peripheral neuropathy). A systematic review and synthesis was conducted to provide evidence for the dimensions that comprise this cancer pain taxonomy. Future efforts will subject these diagnostic categories and criteria to systematic empirical evaluation of their feasibility, reliability, and validity and extension to other cancer-related pain syndromes. The ACTTION-APS chronic cancer pain taxonomy provides an evidence-based classification for 3 prevalent syndromes, namely malignant bone pain, pancreatic cancer pain, and chemotherapy-induced peripheral neuropathy. This taxonomy provides consistent diagnostic criteria, common features, comorbidities, consequences, and putative mechanisms for these potentially serious cancer pain conditions that can be extended and applied with other cancer

Chronic cancer pain is a serious complication of malignancy or its treatment. Currently, no comprehensive, universally accepted cancer pain classification system exists. Clarity in classification of common cancer pain syndromes would improve clinical assessment and management. Moreover, an evidence-based taxonomy would enhance cancer pain research efforts by providing consistent diagnostic criteria, ensuring comparability across clinical trials. As part of a collaborative effort between the A...

Magnetic resonance (MR) imaging for chronic wrist pain is challenging. Correct assessment of the triangular fibrocartilage, hyaline cartilage, ligaments, and tendons has become mandatory for comprehensive decision making in wrist surgery. The MR technique, potential and limits of MR imaging in patients with chronic wrist pain will be discussed. MR arthrography with injection of gadolinium-containing contrast material into the distal radioulnar joint is suggested for evaluation of the triangular fibrocartilage. The clinically meaningful ulnar-sided peripheral tears are otherwise hard to diagnose. The diagnostic performance of MR imaging for interosseous ligament tears varies considerably. The sensitivity for scapholunate ligament tears is consistently better than for lunotriquetral ligament tears. Gadolinium-enhanced MR imaging is considered to be the best technique for detecting established avascularity of bone, but the assessment of the MR results remains challenging. Most cases of ulnar impaction syndrome have characteristic focal signal intensity changes in the ulnar aspect of the lunate. Avascular necrosis of the lunate (Kienboeck's disease) is characterized by signal changes starting in the proximal radial aspect of the lunate. MR imaging is extremely sensitive for occult fractures. Questions arise if occult posttraumatic bone lesions seen on MR images only necessarily require the same treatment as fractures evident on plain films or computed tomography (CT) images. MR imaging and ultrasound are equally effective for detecting occult carpal ganglia. Carpe bossu (carpal boss) is a bony protuberance of a carpometacarpal joint II and III which may be associated with pain. (orig.)

The assessment of emotional factors, in addition to other psychosocial factors, has been recommended as a means of identifying individuals with chronic pain who may not respond to certain pain treatments. Systematic reviews of the evidence regarding the prediction of responsiveness to a treatment called the spinal cord stimulator (SCS) have yielded inconclusive results. Emotional intelligence is a term which refers to the ability to identify and manage emotions in oneself and others and has been shown to be inversely associated with emotional distress and acute pain. This study aims to investigate the relationship between emotional intelligence, chronic pain, and the more established psychosocial factors usually used for SCS evaluations by clinical psychologists in medical settings. A sample of 112 patients with chronic pain on an acute hospital waiting list for SCS procedures in a pain medicine service were recruited. Psychological measures were completed including: a novel measure of emotional intelligence; usual measures of emotional distress and catastrophizing; and a numerical rating scale designed to assess pain intensity, pain-related distress, and interference. As predicted, findings revealed significant associations between most of the measures analyzed and current pain intensity. When entered into a simultaneous regression analysis, emotional intelligence scores remained the only significant predictor of current pain intensity. There are potential clinical, ethical, and organizational implications of emotional intelligence processes partially predicting pain in patients on a waiting list for a medical procedure. These results may offer new insight, understanding, and evaluation targets for clinical psychologists in the field of pain management.

Background and aim Ketamine is a drug used for the induction and maintenance of general anesthesia, for the treatment of postoperative and posttraumatic acute pain, and more recently, for the reduction of postoperative opioid requirements. The main mechanism of action of ketamine is the antagonization of N-methyl-D-aspartate (NMDA) receptors that are associated with central sensitization. In the pathogenesis of chronic pain and particularly in neuropathic pain, an important role is played by ...

Pain in chronic pancreatitis (CP) shows similarities with other visceral pain syndromes (i.e., inflammatory bowel disease and esophagitis), which should thus be managed in a similar fashion. Typical causes of CP pain include increased intrapancreatic pressure, pancreatic inflammation and pancreatic/extrapancreatic complications. Unfortunately, CP pain continues to be a major clinical challenge. It is recognized that ongoing pain may induce altered central pain processing, e.g., central sensitization or pro-nociceptive pain modulation. When this is present conventional pain treatment targeting the nociceptive focus, e.g., opioid analgesia or surgical/endoscopic intervention, often fails even if technically successful. If central nervous system pain processing is altered, specific treatment targeting these changes should be instituted (e.g., gabapentinoids, ketamine or tricyclic antidepressants). Suitable tools are now available to make altered central processing visible, including quantitative sensory testing, electroencephalograpy and (functional) magnetic resonance imaging. These techniques are potentially clinically useful diagnostic tools to analyze central pain processing and thus define optimum management approaches for pain in CP and other visceral pain syndromes. The present review proposes a systematic mechanism-orientated approach to pain management in CP based on a holistic view of the mechanisms involved. Future research should address the circumstances under which central nervous system pain processing changes in CP, and how this is influenced by ongoing nociceptive input and therapies. Thus we hope to predict which patients are at risk for developing chronic pain or not responding to therapy, leading to improved treatment of chronic pain in CP and other visceral pain disorders.

Medicinal cannabis use is topical in the media in Ireland. A recent Health Products Regulatory Authority review, however, has recommended against its use for patients with chronic pain. This is despite evidence for its effectiveness in this patient's cohort and the inadequate pain management of these patients. The aim of this study was to evaluate the attitudes of Irish patients with chronic pain towards medicinal cannabis. After institutional ethics committee approval, a 12-item questionnaire (excluding demographics) was randomly assigned to patients attending a chronic pain clinic (University Hospital Limerick). The questionnaire was designed to incorporate patient's attitudes on a variety of medicinal cannabis related topics. Ninety-six adult patients were surveyed. 88.54% agreed that cannabis should be legalised for chronic pain medicinal purposes. 80.21% believed it would have health benefits for them and 73.96% agreed it would be socially acceptable to use cannabis for this purpose. 33.33% perceived cannabis to be addictive while 68.75% would be willing to try it if prescribed by a medical professional. The study highlights the attitudes of chronic pain patients in Ireland towards medicinal cannabis. It shows their desire to have medical cannabis legalised for chronic pain and that they view it as a reasonable pain management option.

Most pain patients are treated in an outpatient setting and are engaged in daily activities including driving. Since several studies showed that cognitive functioning may be impaired in chronic nonmalignant pain, the question arises whether or not chronic nonmalignant pain affects driving performance. Therefore, the objective of the present study was to determine the effects of chronic nonmalignant pain on actual highway driving performance during normal traffic. Fourteen patients with chronic nonmalignant pain and 14 healthy controls, matched on age, educational level, and driving experience, participated in the study. Participants performed a standardized on-the-road driving test during normal traffic, on a primary highway. The primary parameter of the driving test is the Standard Deviation of Lateral Position (SDLP). In addition, driving-related skills (tracking, divided attention, and memory) were examined in the laboratory. Subjective assessments, such as pain intensity, and subjective driving quality, were rated on visual analogue scales. The results demonstrated that a subset of chronic nonmalignant pain patients had SDLPs that were higher than the matched healthy controls, indicating worse highway driving performance. Overall, there was a statistically significant difference in highway driving performance between the groups. Further, chronic nonmalignant pain patients rated their subjective driving quality to be normal, although their ratings were significantly lower than those of the healthy controls. No significant effects were found on the laboratory tests.

Abstract Chronic pain after joint replacement is common, affecting approximately 10% of patients after total hip replacement (THR) and 20% of patients after total knee replacement (TKR). Heightened generalized sensitivity to nociceptive input could be a risk factor for the development of this pain. The primary aim of this study was to investigate whether preoperative widespread pain sensitivity was associated with chronic pain after joint replacement. Data were analyzed from 254 patients receiving THR and 239 patients receiving TKR. Pain was assessed preoperatively and at 12 months after surgery using the Western Ontario and McMaster Universities Osteoarthritis Pain Scale. Preoperative widespread pain sensitivity was assessed through measurement of pressure pain thresholds (PPTs) at the forearm using an algometer. Statistical analysis was conducted using linear regression and linear mixed models, and adjustments were made for confounding variables. In both the THR and TKR cohort, lower PPTs (heightened widespread pain sensitivity) were significantly associated with higher preoperative pain severity. Lower PPTs were also significantly associated with higher pain severity at 12 months after surgery in the THR cohort. However, PPTs were not associated with the change in pain severity from preoperative to 12 months postoperative in either the TKR or THR cohort. These findings suggest that although preoperative widespread pressure pain sensitivity is associated with pain severity before and after joint replacement, it is not a predictor of the amount of pain relief that patients gain from joint replacement surgery, independent of preoperative pain severity.

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 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.

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.

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.

To describe treatment and referral patterns and National Health Service resource use in patients with chronic pain associated with low back pain or osteoarthritis, from a Primary Care perspective. Osteoarthritis and low back pain are the two commonest debilitating causes of chronic pain, with high health and social costs, and particularly important in primary care. Understanding current practice and resource use in their management will inform health service and educational requirements and the design and optimisation of future care. Multi-centre, retrospective, descriptive study of adults (⩾18 years) with chronic pain arising from low back pain or osteoarthritis, identified through primary care records. Five general practices in Scotland, England (two), Northern Ireland and Wales. All patients with a diagnosis of low back pain or osteoarthritis made on or before 01/09/2006 who had received three or more prescriptions for pain medication were identified and a sub-sample randomly selected then consented to an in-depth review of their medical records (n=264). Data on management of chronic pain were collected retrospectively from patients' records for three years from diagnosis ('newly diagnosed' patients) or for the most recent three years ('established' patients). Patients received a wide variety of pain medications with no overall common prescribing pattern. GP visits represented the majority of the resource use and 'newly diagnosed' patients were significantly more likely to visit their GP for pain management than 'established' patients. Although 'newly diagnosed' patients had more referrals outside the GP practice, the number of visits to secondary care for pain management was similar for both groups. This retrospective study confirmed the complexity of managing these causes of chronic pain and the associated high resource use. It provides an in-depth picture of prescribing and referral patterns and of resource use.
Full Text Available Pain is a subjective experience that alerts an individual to actual or potential tissue damage. Through mechanisms that are still unclear, normal physiological pain can lose its adaptive value and evolve into pathological chronic neuropathic pain. Chronic pain is a multifaceted experience that can be understood in terms of somatosensory, affective, and cognitive dimensions, each with associated symptoms and neural signals. While there have been many attempts to treat chronic pain, in this article we will argue that feedback-controlled ‘closed-loop’ deep brain stimulation (DBS offers an urgent and promising route for treatment. Contemporary DBS trials for chronic pain use “open-loop” approaches in which tonic stimulation is delivered with fixed parameters to a single brain region. The impact of key variables such as the target brain region and the stimulation waveform is unclear, and long-term efficacy has mixed results. We hypothesize that chronic pain is due to abnormal synchronization between brain networks encoding the somatosensory, affective and cognitive dimensions of pain, and that multisite, closed-loop DBS provides an intuitive mechanism for disrupting that synchrony. By (1 identifying biomarkers of the subjective pain experience and (2 integrating these signals into a state-space representation of pain, we can create a predictive model of each patient's pain experience. Then, by establishing how stimulation in different brain regions influences individual neural signals, we can design real-time, closed-loop therapies tailored to each patient. While chronic pain is a complex disorder that has eluded modern therapies, rich historical data and state-of-the-art technology can now be used to develop a promising treatment.

Chronic pain is associated with elevated negative emotions, and resources needed to adaptively regulate these emotions can be depleted during prolonged pain. Studies of links between pain, function, and negative emotions in people with chronic pain, however, have focused almost exclusively on relationships among mean levels of these factors. Indexes that may reflect aspects of emotion regulation have typically not been analyzed. We propose that 1 index of emotion regulation is variability in emotion over time as opposed to average emotion over time. The sample was 105 people with chronic low back pain and 105 of their pain-free spouses. They completed electronic diary measures 5x/d for 14 consecutive days, producing 70 observations per person from which we derived estimates of within-subject variance in negative emotions. Location-scale models were used to simultaneously model predictors of both mean level and variance in patient negative emotions over time. Patients reported significantly more variability in negative emotions compared to their spouses. Patients who reported higher average levels of pain, pain interference, and downtime reported significantly higher levels of variability in negative emotions. Spouse-observed pain and pain behaviors were also associated with greater variability in patients' negative emotions. Test of the inverse associations between negative emotion level and variability in pain and function were significant but weaker in magnitude. These findings support the notion that chronic pain may erode negative emotion regulation resources, to the potential detriment of intra- and inter-personal function.

Treating chronic pain is a complex challenge. While textbooks and medical education classically categorize pain as originating from peripheral (nociceptive), neuropathic, or centralized origins, in real life each and every patient may present a combination of various pain sources, types, and mechanisms. Moreover, individual patients may evolve and develop differing types of pain throughout their clinical follow-up, further emphasizing the necessity to maintain clinical diligence during the evaluation and follow-up of these patients. Rational treatment of patients suffering from chronic pain must attempt at deconstructing complex pain cases, identifying variegate pain generators, and targeting them with appropriate interventions, while incorporating both pharmacological and non-pharmacological strategies, rather than focusing on the total pain level, which represents an integral of all pain types. Failing to recognize the coexistence of different types of pain in an individual patient and escalating medications only on the basis of total pain intensity are liable to lead to both ineffective control of pain and increased untoward effects. In the current review, we outline strategies for deconstructing complex pain and therapeutic suggestions. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Abstract Background Changes of health and quality-of-life in chronic conditions are mostly small and require specific and sensitive instruments. The aim of this study was to determine and compare responsiveness, i.e. the sensitivity to change of five outcome instruments for effect measurement in chronic pain. Methods In a prospective cohort study, 273 chronic pain patients were assessed on the Numeric Rating Scale (NRS for pain, the Short Form 36 (SF-36, the Multidimensional Pain Inventory (MPI, the Hospital Anxiety and Depression Scale (HADS, and the Coping Strategies Questionnaire (CSQ. Responsiveness was quantified by effect size (ES and standardized response mean (SRM before and after a four week in-patient interdisciplinary pain program and compared by the modified Jacknife test. Results The MPI measured pain more responsively than the SF-36 (ES: 0.85 vs 0.72, p = 0.053; SRM: 0.72 vs 0.60, p = 0.027 and the pain NRS (ES: 0.85 vs 0.62, p Conclusion The MPI was most responsive in all comparable domains followed by the SF-36. The pain-specific MPI and the generic SF-36 can be recommended for comprehensive and specific bio-psycho-social effect measurement of health and quality-of-life in chronic pain.

Chronic knee joint pain is one of the most frequent complaints which is seen in the outpatient clinic in our medical institute. In previous studies we have reported the benefits of low level laser therapy (LLLT) for chronic pain in the shoulder joints, elbow, hand, finger and the lower back. The present study is a report on the effects of LLLT for chronic knee joint pain. Over the past 5 years, 35 subjects visited the outpatient clinic with complaints of chronic knee joint pain caused by the knee osteoarthritis-induced degenerative meniscal tear. They received low level laser therapy. A 1000 mW semi-conductor laser device was used to deliver 20.1 J/cm(2) per point in continuous wave at 830nm, and four points were irradiated per session (1 treatment) twice a week for 4 weeks. A visual analogue scale (VAS) was used to determine the effects of LLLT for the chronic pain and after the end of the treatment regimen a significant improvement was observed (pknee joint range of motion. Discussions with the patients revealed that it was important for them to learn how to avoid postures that would cause them knee pain in everyday life in order to have continuous benefits from the treatment. The present study demonstrated that 830 nm LLLT was an effective form of treatment for chronic knee pain caused by knee osteoarthritis. Patients were advised to undertake training involving gentle flexion and extension of the knee.

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

This study aimed to identify clinically meaningful profiles of pain coping strategies used by youth with chronic abdominal pain (CAP). Participants (n=699) were pediatric patients (ages 8-18 years) and their parents. Patients completed the Pain Response Inventory (PRI) and measures of somatic and depressive symptoms, disability, pain severity and pain efficacy, and perceived competence. Parents rated their children's pain severity and coping efficacy. Hierarchical cluster analysis based on the 13 PRI subscales identified pain coping profiles in Sample 1 (n=311) that replicated in Sample 2 (n=388). Evidence was found of external validity and distinctiveness of the profiles. The findings support a typology of pain coping that reflects the quality of patients' pain mastery efforts and interpersonal relationships associated with pain coping. Results are discussed in relation to developmental processes, attachment styles, and treatment implications.

Full Text Available OBJECTIVE: To identify the prevalence and characteristics of chronic pain in schizophrenic patients and to compare the quality of life in patients with and without chronic pain. METHODS: Crossover design with a probablistic sample of 205 adult schizophrenic outpatients (80% paranoid schizophrenia. Socio-demographic, psychiatric disorder, pain and quality of life (WHOQOL- brief data were collected between June and September 2008. RESULTS: Mean age was 37 years, 65% were men, and the mean time spent in school was 9 years; 87% were single, 65% lived with parents and 25% had a job. Among patients with chronic pain, 70% did not receive treatment for pain. Regarding quality of life, patients with pain had more physical disabilities compared to those without pain (p < .001. There were no differences in other domains. Comparisons between patients with and without pain did not show any differences in how much they felt their mental health problems disabled them. Conclusion: Chronic pain was common in schizophrenic patients (similar to the general population of a similar age and decreased their quality of life. It is necessary to pay more attention to this co-morbidity.
Full Text Available Current treatments for chronic pain, such as inflammatory pain, neuropathic pain, and cancer pain are insufficient and cause severe side effects. Mounting evidence suggests that neuroinflammation in the peripheral and central nervous system (PNS and CNS plays a pivotal role in the genesis and maintenance of chronic pain. Characteristic features of neuroinflammation in chronic pain conditions include infiltration of immune cells into the PNS [e.g., the sciatic nerve and dorsal root ganglion (DRG], activation of glial cells such as microglia and astrocytes in the CNS (spinal cord and brain, and production and secretion of pro-inflammatory cytokines and chemokines [TNF, interleukin (IL-1β, IL-6, CCL2, and CXCL1]. Recent studies suggest that bone marrow stem cells or bone marrow stromal cells (BMSCs produce powerful analgesic effects in animal models of inflammatory pain, neuropathic pain, and cancer pain. We recently demonstrated that intrathecal injection of BMSCs resulted in a long-term relief of neuropathic pain for several weeks after peripheral nerve injury. Strikingly, this analgesic effect is mediated by the anti-inflammatory cytokine transforming growth factor beta secreted from BMSCs. Additionally, BMSCs exhibit potent modulation of neuroinflammation, by inhibiting monocyte infiltration, glial activation, and cytokine/chemokine production in the DRG and spinal cord. Thus, BMSCs control chronic pain by regulation of neuroinflammation in the PNS and CNS via paracrine signaling. In this review, we discuss the similar results from different laboratories of remarkable anti-nociceptive efficacy of BMSCs in animal and clinical studies. We also discuss the mechanisms by which BMSCs control neuroinflammation and chronic pain and how these cells specifically migrate to damaged tissues.
Full Text Available Abstract Objectives Alexithymia is highly prevalent among chronic pain patients. Pain is a remarkable cause for high levels of chronic anxiety. The purpose of this study was to investigate the prevalence of alexithymia and to determine anxiety levels among DSM-IV somatoform pain disorder (chronic pain female patients and to examine the relationship between alexithymia and the self-reporting of pain. Methods Thirty adult females (mean age: 34,63 ± 10,62 years, who applied to the outpatient psychiatry clinic at a public hospital with the diagnosis of chronic pain disorder (DSM-IV, were included in the study. Thirty seven healthy females (mean age: 34,46 ± 7,43 years, who matched for sociodemographic features with the patient group, consisted the control group. A sociodemographic data form, 26-item Toronto Alexithymia Scale (TAS-26, Spielberger Trait Anxiety Inventory (STAI were administered to each subject and information was obtained on several aspects of the patients' pain, including intensity (measured by VAS, and duration. Results Chronic pain patients were found significantly more alexithymic than controls. There was a positive correlation between TAS-26 scores and the duration of pain. The alexithymic and nonalexithymic group did not differ in their perception of pain. Neither positive correlation nor significant difference was found between alexithymia and trait anxiety in pain patients. Discussion Alexithymia may be important in addressing the diversity of subjective factors involved in pain. The conceptualization of alexithymia as a personality trait as well as a secondary state reaction is underlined by our data.
Full Text Available A growing body of empirical research has confirmed an association between chronic pain and cognitive dysfunction. The aim of the present study was to determine whether cognitive function is affected in patients with a diagnosis of chronic neuropathic or radicular pain relative to healthy control participants matched by age, gender, and years of education. We also examined the interaction of pain with age in terms of cognitive performance. Some limitations of previous clinical research investigating the effects of chronic pain on cognitive function include differences in the pain and cognitive scale materials used, and the heterogeneity of patient participants, both in terms of their demographics and pathological conditions. To address these potential confounds, we have used a relatively homogenous patient group and included both experimental and statistical controls. We have also specifically investigated the interaction effect of pain and age on cognitive performance. Patients (n = 38 and controls (n = 38 were administered a battery of cognitive tests measuring IQ, spatial and verbal memory, attention, and executive function. Educational level, depressive symptoms, and state anxiety were assessed as were medication usage, caffeine, and nicotine consumption to control for possible confounding effects. Both the level of depressive symptoms and the state anxiety score were higher in chronic pain patients than in matched control participants. Chronic pain patients had a lower estimated IQ than controls, and showed impairments on measures of spatial and verbal memory. Attentional responding was altered in the patient group, possibly indicative of impaired inhibitory control. There were significant interactions between chronic pain condition and age on a number of cognitive outcome variables, such that older patients with chronic pain were more impaired than both age-matched controls and younger patients with chronic pain. Chronic pain did not appear
Full Text Available Objective To investigate the correlation of chronic pain after surgery and acute pain within 48 h after temporal craniotomy. 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.
Full Text Available Patients with chronic pain and depression are more likely to develop opioid abuse compared to patients without depression. It is not known if this association differs by pain location. We compared the strength of association between depression and opioid misuse in patients with chronic low back pain (CLBP vs. chronic pain of other location (CPOL. Chart abstracted data was obtained from 166 patients seeking care in a family medicine clinic. Depression was measured by the PHQ-9 and opioid misuse was measured using the Current Opioid Misuse Measure. Pain severity and interference questions came from the Brief Pain Inventory. Cross-tabulations were computed to measure the association between depression and opioid misuse stratified on pain location. Exploratory logistic regression modeled the association between depression and opioid misuse after adjusting for pain location and pain severity and interference. Depression was significantly associated with opioid misuse in CPOL but not in CLBP. Regression results indicate pain interference partly accounts for the depression–opioid misuse association. These preliminary results from a small patient sample suggest depression may co-occur with opioid misuse more often in CPOL than in CLBP. Further research is needed to compare this comorbidity in specific pain diagnoses such as arthritis, fibromyalgia and CLBP.

Sleeping problems are very common in patients with chronic pain. The aim of the study was to investigate the association between different dimensions of chronic pain and sleep quality in chronic pain patients. In this cross-sectional interview-based questionnaire study, patients from 3 different pain treatment centers in Vienna aged 18-65 years, with pain lasting 3 months or longer were asked to participate. The association between the short-form McGill pain questionnaire (SF-MPQ) and sleep quality (sleep onset latency, interrupted sleep due to pain, sleep duration and recovering effect of sleep) was assessed. In this study 121 patients (male 32, female 89, mean age 49 ± 9 years) could be analyzed. Of the patients 38.8% needed more than 30 min for falling asleep, 63.6% reported sleep fragmentation, 30.6% slept less than 5 h and 60.3% reported no recovering effect of sleep. The strongest associations between pain characteristics and sleep quality were found for pain intensity and affective pain aspects. Logistic regression analyses revealed that one point more in the total score of SF-MPQ increased the odds of needing more than 30 min for falling asleep, waking up more than 3 times due to pain, sleeping less than 5 h, and perceiving the sleep as non-recovering, by 6%. Adjusting for physical and psychological quality of life lowered the odds ratios and the association was no longer significant. The results underline the importance of paying attention to sleep quality in patients with chronic pain. The results also indicate that psychological factors might mediate the association between pain and sleep quality.

Background The reported prevalence of chronic pain ranges from 11% to 64%, and although consistently high, the calculated economic burden estimates also vary widely between studies. There is no standard way of classifying chronic pain. We have repeated measurements of pain in a longitudinal population study to improve validity ofthe case ascertainment. In this paper, associations between chronic pain and demographic characteristics, self reported health and functioning, work Incapacity and health care use were investigated in a sample from the general Norwegian population. Methods A random sample of 6419 participants from a population study (the HUNT 3 Study) was invited to report pain every three months during a 12 month period. Chronic pain was defined as moderate pain or more (on the SF-8 verbal rating scale) in at least three out of five consecutive measurements. Self reported health and functioning was measured by seven of the eight subscales on the SF-8 health survey (bodily pain was excluded). Health care utilisation during the past 12 months was measured by self report, and included seeing a general practitioner, seeing a medical specialist and seeing other therapists. The survey data was combined with information on income, education, disability pension awards and unemployment by Statistics Norway, which provided data from the National Education database (NUDB) and the Norwegian Labour and Welfare Administration (NAV). Results The total prevalence of chronic pain was 36% (95% CI34-38) among women and 25% (95% CI 22-26) among men. The prevalence increased with age, was higher among people with high BMI, and in people with low income and low educational level. Smoking was also associated with a higher prevalence of chronic pain. Subjects in the chronic pain group had a self-reported health and functioning in the range of 1-2.5 standard deviations below that of those without chronic pain. Among the chronic pain group 52% (95% CI 49-55), of participants

Objective To offer preliminary guidance on prescribing smoked cannabis for chronic pain before the release of formal guidelines. Quality of evidence We reviewed the literature on the analgesic effectiveness of smoked cannabis and the harms of medical and recreational cannabis use. We developed recommendations on indications, contraindications, precautions, and dosing of smoked cannabis, and categorized the recommendations based on levels of evidence. Evidence is mostly level II (well conducted observational studies) and III (expert opinion). Main message Smoked cannabis might be indicated for patients with severe neuropathic pain conditions who have not responded to adequate trials of pharmaceutical cannabinoids and standard analgesics (level II evidence). Smoked cannabis is contraindicated in patients who are 25 years of age or younger (level II evidence); who have a current, past, or strong family history of psychosis (level II evidence); who have a current or past cannabis use disorder (level III evidence); who have a current substance use disorder (level III evidence); who have cardiovascular or respiratory disease (level III evidence); or who are pregnant or planning to become pregnant (level II evidence). It should be used with caution in patients who smoke tobacco (level II evidence), who are at increased risk of cardiovascular disease (level III evidence), who have anxiety or mood disorders (level II evidence), or who are taking higher doses of opioids or benzodiazepines (level III evidence). Cannabis users should be advised not to drive for at least 3 to 4 hours after smoking, for at least 6 hours after oral ingestion, and for at least 8 hours if they experience a subjective “high” (level II evidence). The maximum recommended dose is 1 inhalation 4 times per day (approximately 400 mg per day) of dried cannabis containing 9% delta-9-tetrahydrocannabinol (level III evidence). Physicians should avoid referring patients to “cannabinoid” clinics (level

This study examined the relation between level of educational achievement (LOE) and the clinical morbidity associated with chronic pain. a multidisciplinary pain rehabilitation program located within a university hospital. Two hundred ninety-nine consecutive patients with chronic spinal pain, average age 39.6 years (SD = 10.7) and with an average duration of pain of 41.9 months (SD = 51.6). Age, duration of pain, sex, and compensation and litigation status were controlled for in the statistical analysis because each was found to be significantly associated with LOE. Pain intensity was assessed by the McGill Pain Questionnaire. Affective distress was assessed by the Global Severity Index from the Brief Symptom Inventory. Severity of depressive symptoms was derived from scores from the Center for Epidemiological Studies-Depression Scale. Pain beliefs and pain coping strategies were assessed by the Survey of Pain Attitudes and the Coping Strategies Questionnaire, respectively. Finally, self-report of pain-related disability was assessed by the Pain Disability Index. After controlling for relevant covariates, LOE was unrelated to pain intensity, severity of depressive symptoms, or affective distress, but was inversely related to self-reported disability. Persons with lower LOEs possessed a greater belief that pain is a "signal of harm," unrelated to emotional experience, disabling and uncontrollable. They also endorsed more passive and maladaptive coping strategies, including a tendency to catastrophize about their pain. Path analysis indicated that, after controlling for the influence of both the belief that pain is a "signal of harm" and catastrophizing on the association between LOE and disability, this relation loses statistical significance. These results suggest that pain-related cognitions mediate the relation between LOE and pain disability and that persons with lower LOEs are more likely to develop maladaptive pain beliefs and coping strategies.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common male pain condition that is associated with significant discomfort and disability. Despite significant efforts, there remains no definitive etiology or treatment of the spectrum of pelvic symptoms reported by these patients. The purpose of this review is to summarize important clinical and scientific findings related to CP/CPPS from the previous 2 years, and to evaluate their impact on our understanding of, and approach to, the disease.

Full Text Available Visceral pain is generally poorly localized and characterized by hypersensitivity to a stimulus such as organ distension. In concert with chronic visceral pain, there is a high comorbidity with stress-related psychiatric disorders including anxiety and depression. The mechanisms linking visceral pain with these overlapping comorbidities remain to be elucidated. Evidence suggests that long term stress facilitates pain perception and sensitizes pain pathways, leading to a feed-forward cycle promoting chronic visceral pain disorders such as irritable bowel syndrome (IBS. Early life stress (ELS is a risk-factor for the development of IBS, however the mechanisms responsible for the persistent effects of ELS on visceral perception in adulthood remain incompletely understood. In rodent models, stress in adult animals induced by restraint and water avoidance has been employed to investigate the mechanisms of stress-induce pain. ELS models such as maternal separation, limited nesting, or odor-shock conditioning, which attempt to model early childhood experiences such as neglect, poverty, or an abusive caregiver, can produce chronic, sexually dimorphic increases in visceral sensitivity in adulthood. Chronic visceral pain is a classic example of gene × environment interaction which results from maladaptive changes in neuronal circuitry leading to neuroplasticity and aberrant neuronal activity-induced signaling. One potential mechanism underlying the persistent effects of stress on visceral sensitivity could be epigenetic modulation of gene expression. While there are relatively few studies examining epigenetically mediated mechanisms involved in visceral nociception, stress-induced visceral pain has been linked to alterations in DNA methylation and histone acetylation patterns within the brain, leading to increased expression of pro-nociceptive neurotransmitters.

Little research is available concerning physical activity and its determinants in people with chronic neck pain. To explore the relation between kinesiophobia and physical activity and gender effect on these relations in people with chronic neck pain. Ninety-nine subjects (34 men and 65 women) with chronic neck pain were participated in the study. Pain intensity was assessed with Visual Analog Scale and kinesiophobia degree was determined by using Tampa Scale of Kinesiophobia. Level of physical activity was assessed with short form of the International Physical Activity Questionnaire. There was no statistically correlation between neck pain intensity and kinesiophobia degree (p= 0.246, r= 0.123) and physical activity level (p= 0.432, r= -0.083). It was also found that kinesiophobia degree was not correlated to physical activity level (p= 0.148, r= -0.153). There was a negative correlation between kinesiophobia degree and physical activity level only for women, not for men (p= 0.011, r= -0.318). Our results showed that although people with chronic neck pain reported higher pain intensity and fear of movement, pain intensity and kinesiophobia degree did not associate to their physical activity levels. It can be speculated that high kinesiophobia degrees cause low physical activity levels for women, but not for men.

Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain. Keywords: vulvar pain, genitofemoral nerve, neuropathic pain, vulvodynia, vulvar disease

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

The complicated nature of chronic pain involves an interplay between psychological and physical factors, often resulting in increased emotional distress and reduced quality of life. This review is designed to help the medical practitioner who is working with chronic pain patients to be aware of psychological assessment techniques that can add to comprehensive patient understanding and more effectively guide treatment. Enhanced ability to assess and understand the emotional life of the chronic pain patient provides a basis for intervening and treating more successfully. There are a broad range of assessment techniques, some of which require a background in psychology and some that do not, that can identify psychological differences in chronic pain patients and serve to guide intervention strategies. Chronic pain is often comorbid with depression, anxiety, catastrophizing, and various ineffective coping strategies. Some patients, however, have demonstrated more adaptive and effective strategies for cognitively and behaviorally coping with pain and normalizing their lives. Proper assessment enables the individualization of treatment to overcome and/or build upon each patient's psychological frame of mind to maximize the potential for effective functioning. The use of standardized and documented psychological assessment techniques can lead to a better understanding of chronic pain patients and contribute in ways that can enhance response to medical treatment and improve quality of life. It is recommended that certain psychological tools be included to supplement the medical assessment of patients who have chronic pain. A basic assessment can include a short psychological-based clinical interview along with brief measures of depression, anxiety, and coping strategies. It is also recommended that the pain physician have access to professional psychological practitioners as a resource for more complicated assessments and psychological intervention services.

Autoantibodies targeting voltage-gated potassium channel (VGKC) complexes cause a spectrum of neuronal hyperexcitability disorders. We investigated pain as a manifestation of VGKC-complex autoimmunity. We reviewed the prevalence and characteristics of pain in VGKC-complex-immunoglobulin G (IgG)-seropositive patients in 25 months of comprehensive service testing for neural autoantibodies, subtyped positive sera for LGI1-IgG and CASPR2-IgG specificities, and reviewed pain prevalence in autoimmune control patients. VGKC-complex-IgG was identified in 1,992 patients of 54,853 tested (4%). Of 316 evaluated neurologically at Mayo Clinic, 159 (50%) had pain, in isolation (28%) or with accompanying neurologic manifestations (72%), and not attributable to alternative cause. Pain was subacute in onset, chronic in course, neuropathic, nociceptive, regional, or diffuse and sometimes attributed to fibromyalgia (6%) or psychogenic cause (13%). Most patients had normal peripheral nervous system function, measured by neuropathy impairment scores and nerve conduction. Evidence of neuronal hyperexcitability (hyperhidrosis, quantitative heat-pain hyperalgesia, or electromyographic excitability) was 25-fold more common in pain patients. Pain management required multiple medications in 70% (narcotics, 30%); 13 of 16 patients reported pain relief with immunotherapy. Pain was significantly associated with CASPR2-IgG-positivity (16% positive with pain, 7% without pain; p = 0.014) but not with LGI1-IgG. Less than 10% of 167 patients with neural autoantibodies other than VGKC-complex-IgG reported pain. Chronic idiopathic pain is a syndromic manifestation of VGKC-complex autoimmunity. Hyperexcitability of nociceptive pathways is implicated. CASPR2-IgG significantly associates with pain, but in most patients the antigenic VGKC-complex molecule remains to be determined. VGKC-complex autoimmunity represents an important new direction for pain research and therapy.

Digital health is an increasingly popular tool for patient engagement, having shown great success in arenas such as medication adherence, management of chronic conditions, and patient safety. Given the growth of chronic pain diagnoses, it is imperative to find new technologies to improve care for this particular population. Little research has catalogued the use of digital health in the chronic pain patient population. This manuscript's objective was to describe current patterns of digital health usage among chronic pain patients and how digital health use correlates with health care utilization and health outcomes. A cross-sectional survey was administered to patients with a self-identified chronic pain diagnosis participating in 'Patients Like Me' ® (PLM), an organization that directly collects data from patients experiencing chronic health conditions, with emphasis on patient-centered outcomes and experiences interacting with the health care system. Validated measures of healthcare utilization, chronic pain management, and digital health use were adapted for the survey. Digital health was defined as the use of online sites, social media, and mobile phone applications before, during, or after healthcare utilization. Descriptive statistics, chi square tests, logistic regression, and linear regression were used as appropriate for analysis. Among 565 respondents (mean age 51.3, 87.2% female, 45.7% publicly insured), most participants (89.5%) reported some digital health use. Females and users below the age of 50 were more likely to use multiple forms of digital health. Healthcare utilization, education level, and race/ethnicity did not correlate with digital health use. Patients using more types of digital health reported significantly higher levels of pain coping skills in the realms of social support, relaxation, and exercise. Digital health use is common among a wide range of patients with chronic pain diagnoses. The use of multiple forms of digital health is

Spinal cord stimulation (SCS) has been in clinical use for nearly four decades. In earliest observations, researchers found a significant increase in pain threshold during SCS therapy without changes associated with touch, position, and vibration sensation. Subsequent studies yielded diverse results regarding how SCS impacts pain and other sensory thresholds. This pilot study uses quantitative sensory testing (QST) to objectively quantify the impact of SCS on warm sensation, heat pain threshold, and heat pain tolerance. Nineteen subjects with an indwelling SCS device for chronic pain were subjected to QST with heat stimuli. QST was performed on an area of pain covered with SCS-induced paresthesia and an area without pain and without paresthesia, while the SCS was turned off and on. The temperature at which the patient detected warm sensation, heat pain, and maximal tolerable heat pain was used to define the thresholds. We found that all three parameters, the detection of warm sensation, heat pain threshold, and heat pain tolerance, were increased during the period when SCS was on compared with when it was off. This increase was observed in both painful and non-painful sites. The observed pain relief during SCS therapy seems to be related to its impact on increased sensory threshold as detected in this study. The increased sensory threshold on areas without pain and without the presence of SCS coverage may indicate a central (spinal and/or supra-spinal) influence from SCS. © 2015 International Neuromodulation Society.

Chronic pain in vulnerable elderly people is still poorly recognized and treated, both at home and in hospitals and care and nursing homes. Vulnerable elderly people experience and express pain differently to relatively healthy adults, especially when they suffer from cognitive impairment or specific conditions. Determining the nature and severity of the pain requires the use of pain assessment instruments that have been validated for use in vulnerable elderly people. Effective treatment of pain demands careful diagnosis and pharmacological and non-pharmacological interventions that have proven effectiveness in vulnerable elderly people. The combination of multiple morbidity and poly-pharmacy increases the chance of side-effects and complications. In addition, the pharmacokinetic and pharmacodynamic characteristics of many drugs are different in vulnerable elderly people. The advice is to start with a lower dose of pain medication and gradually build up a level on the basis of pain relief and side-effects ('start low, go slow!').

Abstract Objective To provide family physicians with a practical clinical summary of the Canadian Pain Society (CPS) revised consensus statement on the pharmacologic management of neuropathic pain. Quality of evidence A multidisciplinary interest group within the CPS conducted a systematic review of the literature on the current treatments of neuropathic pain in drafting the revised consensus statement. Main message Gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors are the first-line agents for treating neuropathic pain. Tramadol and other opioids are recommended as second-line agents, while cannabinoids are newly recommended as third-line agents. Other anticonvulsants, methadone, tapentadol, topical lidocaine, and botulinum toxin are recommended as fourth-line agents. Conclusion Many pharmacologic analgesics exist for the treatment of neuropathic pain. Through evidence-based recommendations, the CPS revised consensus statement helps guide family physicians in the management of patients with neuropathic pain. PMID:29138154

To describe the development and initial application of the Chronic Pain Coding System. Secondary analysis of data from a randomized clinical trial. Six primary care clinics in northern California. Forty-five primary care visits involving 33 clinicians and 45 patients on opioids for chronic noncancer pain. The authors developed a structured coding system to accurately and objectively characterize discussions about pain and opioids. Two coders applied the final system to visit transcripts. Intercoder agreement for major coding categories was moderate to substantial (kappa = 0.5-0.7). Mixed effects regression was used to test six hypotheses to assess preliminary construct validity. Greater baseline pain interference was associated with longer pain discussions (P = 0.007) and more patient requests for clinician action (P = 0.02) but not more frequent negative patient evaluations of pain (P = 0.15). Greater clinician-reported visit difficulty was associated with more frequent disagreements with clinician recommendations (P = 0.003) and longer discussions of opioid risks (P = 0.049) but not more frequent requests for clinician action (P = 0.11). Rates of agreement versus disagreement with patient requests and clinician recommendations were similar for opioid-related and non-opioid-related utterances. This coding system appears to be a reliable and valid tool for characterizing patient-clinician communication about opioids and chronic pain during clinic visits. Objective data on how patients and clinicians discuss chronic pain and opioids are necessary to identify communication patterns and strategies for improving the quality and productivity of discussions about chronic pain that may lead to more effective pain management and reduce inappropriate opioid prescribing. © 2016 American Academy of Pain Medicine.

There is increasing evidence to suggest that anxiety is related more strongly to chronic pain experience in men relative to women. The aim of the present study was to examine for the first time gender-specific associations between anxiety and chronic pain experience in men and women exposed to whiplash trauma. One thousand seven hundred and nine people with whiplash (1349 women, 360 men) belonging to the Danish Society for Polio, Traffic, and Accident Victims completed a battery of questionnaires measuring demographic, psychologic, and pain-related factors (including frequency of painful episodes, level of pain interference, number of anatomic regions in which pain was felt, and the level of general disability). Anxiety was found to be positively related to the level of general disability to a significantly stronger magnitude in men compared with women. A trend difference in correlation magnitude was also found between men and women when comparing anxiety with pain frequency, with the magnitude of correlation being higher in men. The stronger association between anxiety and symptoms of whiplash trauma in men compared with women may be due to gender differences in the attribution of anxiety-related autonomic arousal as symptoms of whiplash injury. Alternatively, anxiety may differentially affect the willingness of men and women to report pain and other health indices. Anxiety is an important factor in understanding gender differences in whiplash-related symptoms such as chronic pain and disability, and requires further investigation.

To investigate to what extent a single 60-minute session of transcutaneous electrical nerve stimulation (TENS) would modify chronic clinical pain, acute experimental pain, and the flexion reflex evoked in chronic low back pain patients. Thirty young subjects with chronic low back pain were randomly allocated to two groups, receiving either TENS or placebo stimulation to the lumbosacral region for 60 minutes. The flexion reflex was elicited by an electrical stimulation applied to the subject's right sole and recorded electromyographically from the biceps femoris and the tibialis anterior muscles. Subjective sensation of low back pain and the electrically induced pain were measured by two separate visual analog scales, termed VAS(LBP) and VAS(FR), respectively. Data obtained before, during, and 60 minutes after TENS and placebo stimulations were analyzed using repeated measures ANOVA. The VAS(LBP) score was significantly reduced to 63.1% of the prestimulation value after TENS (pTENS protocol had different degrees of antinociceptive influence on chronic and acute pain in chronic low back pain patients.

After reviewing how psychological treatment for chronic pain comes to have its current form, and summarizing treatment effectiveness, we explore several areas of development. We describe third wave therapies, such as mindfulness; we discuss what the research literature aggregated can tell us about what trials are more useful to conduct; and we outline some areas of promise and some failures to deliver on promise. The article is drawn together using the framework of the normal psychology of pain, identifying some of its most important implications for improving life for people with chronic pain. PMID:26174216

Pain and stress share significant conceptual and physiological overlaps. Both phenomena challenge the body's homeostasis and necessitate decision-making to help animals adapt to their environment. In addition, chronic stress and chronic pain share a common behavioral model of failure to extinguish negative memories. Yet, they also have discrepancies such that the final brain endophenotype of posttraumatic stress disorder, depression, and chronic pain appears to be different among the three conditions, and the role of the hypothalamic-pituitary-adrenal axis remains unclear in the physiology of pain. Persistence of either stress or pain is maladaptive and could lead to compromised well-being. In this brief review, we highlight the commonalities and differences between chronic stress and chronic pain, while focusing particularly on the central role of the limbic brain. We assess the current attempts in the field to conceptualize and understand chronic pain, within the context of knowledge gained from the stress literature. The limbic brain-including hippocampus, amygdala, and ventromedial pre-frontal cortex-plays a critical role in learning. These brain areas integrate incoming nociceptive or stress signals with internal state, and generate learning signals necessary for decision-making. Therefore, the physiological and structural remodeling of this learning circuitry is observed in conditions such as chronic pain, depression, and posttraumatic stress disorder, and is also linked to the risk of onset of these conditions.

Chronic low back pain: Chronic pain is the most common cause for people to utilize healthcare resources and has a considerable impact upon patients' lives. The most prevalent chronic pain condition is chronic low back pain (CLBP). CLBP may be nociceptive or neuropathic, or may incorporate both components. The presence of a neuropathic component is associated with more intense pain of longer duration, and a higher prevalence of co-morbidities. However, many physicians' knowledge of chronic pain mechanisms is currently limited and there are no universally accepted treatment guidelines, so the condition is not particularly well managed. Diagnosis should begin with a focused medical history and physical examination, to exclude serious spinal pathology that may require evaluation by an appropriate specialist. Most patients have non-specific CLBP, which cannot be attributed to a particular cause. It is important to try and establish whether a neuropathic component is present, by combining the findings of physical and neurological examinations with the patient's history. This may prove difficult, however, even when using screening instruments. Multimodal management: The multifactorial nature of CLBP indicates that the most logical treatment approach is multimodal: i.e. integrated multidisciplinary therapy with co-ordinated somatic and psychotherapeutic elements. As both nociceptive and neuropathic components may be present, combining analgesic agents with different mechanisms of action is a rational treatment modality. Individually tailored combination therapy can improve analgesia whilst reducing the doses of constituent agents, thereby lessening the incidence of side effects. This paper outlines the development of CLBP and the underlying mechanisms involved, as well as providing information on diagnosis and the use of a wide range of pharmaceutical agents in managing the condition (including NSAIDs, COX-2 inhibitors, tricyclic antidepressants, opioids and

We performed single photon emission computed tomography (SPECT) of the brain in 15 patients with chronic pain (males, 7; females, 8; average age 49.1±17.9 years) and identified the locus of cerebral blood flow reduction by a new analytical method (easy Z-score Imaging System: eZIS) to clarify the functional neuroanatomical basis of chronic pain. Of the 15 patients, 6 had backache, 2 neck pain, 2 gonalgia, and 5 pain at other sites, with an average Visual analog scale of pain (VAS) value of 6.1±1.9. In comparison with a information on a data base on physically unimpaired persons, the dorsolateral prefrontal area (both sides, right dominant), medial prefrontal area (both sides), dorsal aspect of the anterior cingulate gyrus nociceptive cortex (both sides) and the lateral part of the orbitofrontal cortex (right side) were found to have blood flow reduction in the group of patients with chronic pain. As for chronic pain and its correlation with clinical features such as a depressive state, anticipation anxiety, post-traumatic stress disorder (PTSD), and conversion hysteria, the mechanism in the brain that was suggested by this study should be followed-up by functional neuroimaging studies.

Chronic pain is common, and the available treatments do not provide adequate relief for most patients. Neuromodulatory interventions that modify brain processes underlying the experience of pain have the potential to provide substantial relief for some of these patients. The purpose of this Review is to summarize the state of knowledge regarding the efficacy and mechanisms of noninvasive neuromodulatory treatments for chronic pain. The findings provide support for the efficacy and positive side-effect profile of hypnosis, and limited evidence for the potential efficacy of meditation training, noninvasive electrical stimulation procedures, and neurofeedback procedures. Mechanisms research indicates that hypnosis influences multiple neurophysiological processes involved in the experience of pain. Evidence also indicates that mindfulness meditation has both immediate and long-term effects on cortical structures and activity involved in attention, emotional responding and pain. Less is known about the mechanisms of other neuromodulatory treatments. On the basis of the data discussed in this Review, training in the use of self-hypnosis might be considered a viable ‘first-line’ approach to treat chronic pain. More-definitive research regarding the benefits and costs of meditation training, noninvasive brain stimulation and neurofeedback is needed before these treatments can be recommended for the treatment of chronic pain.

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.
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.

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. However, results need to be interpreted with caution given the small sample size. Keywords: individual coping, dyadic coping, social support, chronic pain

Full Text Available Low back pain (LBP is a very common syndrome that is associated with the extremely high rate of temporary disability and the development of chronic pain syndrome. In addition to structural changes in the locomotor system, psychological and social factors contribute to the development and maintenance of chronic pain. Drug therapy for chronic LBP frequently gives rise to complications. A physician’s important task in this situation is to prevent pain chronization and to reduce the risk of side effects of treatment. One of the ways to solve this task is to use the vitamin B complex (milgamma along with analgesics and myorelaxants. The review considers the possible effects of combination therapy in patients with LBP and discusses whether it should be used.

The aim of this study was to examine the effects of experiential avoidance (EA) on the indirect relationship of chronic pain patients' illness representations to pain interference, through pain catastrophising Design and main outcome measure: The sample consisted of 162 patients diagnosed with an arthritis-related or a musculoskeletal disorder. The effects of EA on the pathway between illness representations, pain catastrophising and pain interference were examined with PROCESS, a computational tool for SPSS Results: After controlling for patient and illness-related variables and pain severity, the 'illness representations-pain catastrophising-pain interference' pathway was interrupted at the higher levels of EA. The reason was that, at the high levels of EA, either the relation of illness representations to pain catastrophising or the relation of pain catastrophising to pain interference was not statistically significant. The findings indicate that EA is not a generalised negative response to highly aversive conditions, at least as far as the factors examined in this study are concerned. EA may rather reflect a coping reaction, the impact of which depends on its specific interactions with the other aspects of the self-regulation mechanism. At least in chronic pain, EA should become the focus of potential intervention only when its interaction with the illness-related self-regulation mechanism results in negative outcomes.

The patient-physician encounter forms the cornerstone of every health service. However, optimal medical outcomes are often confounded by inadequate patient-physician communication. Chronic pain is estimated to affect over 25% of the population. Its effects are multifaceted with patients at increased risk of experiencing emotional and functional disturbances. Therefore, it is crucial to address all components of the patient's pain experience, including beliefs and expectations. It is our understanding that no other study to date has evaluated the expectations of physicians and compared them to those of patients for pain clinic visits. We sought to describe and compare expectations of chronic pain patients and their physicians during a clinic consultation. We performed a retrospective review on patients attending the pain clinic for the first time who were enrolled and completed a questionnaire asking their expectations for their clinic visit as well as outcomes that would satisfy and disappoint them. Pain physicians were also included. We compared physicians' to patients' responses and evaluated relationships between patient responses and age, gender, pain location, Pain Self-Efficacy, Pain Catastrophizing Scale, and the Hospital Anxiety and Depression Scale. One hundred chronic pain patients and 10 pain physicians were surveyed. Patients' clinical expectations for visits focused primarily on some pain relief (34%), education on the cause of pain (24%), and a definitive diagnosis (18%). Physician's expectations included formulation and communication of a management plan (70%), patient assessment for cause of pain (50%), and the education of patients on the cause of pain (40%) as important aims. Pain relief would satisfy the majority of patients (74%) and physicians (70%). No improvement would cause greatest dissatisfaction for patients (52%), but causing more harm would be disappointing to physicians (50%). Gender, age, pain location, and sleep quality all

The purpose of this study was to explore the literature on chronic pain in adults with Marfan syndrome (MFS), critically appraising and synthesizing relevant literature. A systematic review was conducted by searching the published literature databases using available medical, physical, psychological, social databases and other sources. All studies that addressed pain in MFS, published in peer-reviewed journals were assessed. Of 351 search results, 18 articles satisfied the eligibility criteria. All studies were cross-sectional and quantitative; no randomized controlled trials or intervention studies were found. Most studies had small sample sizes, low response rates and mainly dealt with other aspects of the diagnosis than pain. Only one article dealt mainly with pain. The research on chronic pain in MFS is limited in size and quality. Despite these limitations, studies describe that the prevalence of pain in patients with MFS is high, varying from 47 to 92% and affecting several anatomic sites. In addition, chronic pain limits daily function and few studies describe treatment options for pain in patients with MFS. Research is needed to obtain more evidence-based knowledge for developing more appropriate rehabilitation programs for people with MFS. © 2015 John Wiley & Sons A/S.

Pain acceptance is the process of giving up the struggle with pain and learning to live a worthwhile life despite it. In assessing patients with chronic pain in Turkey, making a diagnosis and tracking the effectiveness of treatment is done with scales that have been translated into Turkish. However, there is as yet no valid and reliable scale in Turkish to assess the acceptance of pain. To validate a Turkish version of the Chronic Pain Acceptance Questionnaire developed by McCracken and colleagues. Methodological and cross sectional study. A simple randomized sampling method was used in selecting the study sample. The sample was composed of 201 patients, more than 10 times the number of items examined for validity and reliability in the study, which totaled 20. A patient identification form, the Chronic Pain Acceptance Questionnaire, and the Brief Pain Inventory were used to collect data. Data were collected by face-to-face interviews. In the validity testing, the content validity index was used to evaluate linguistic equivalence, content validity, construct validity, and expert views. In reliability testing of the scale, Cronbach’s α coefficient was calculated, and item analysis and split-test reliability methods were used. Principal component analysis and varimax rotation were used in factor analysis and to examine factor structure for construct concept validity. The item analysis established that the scale, all items, and item-total correlations were satisfactory. The mean total score of the scale was 21.78. The internal consistency coefficient was 0.94, and the correlation between the two halves of the scale was 0.89. The Chronic Pain Acceptance Questionnaire, which is intended to be used in Turkey upon confirmation of its validity and reliability, is an evaluation instrument with sufficient validity and reliability, and it can be reliably used to examine patients’ acceptance of chronic pain.

Recent data demonstrate that dry eye (DE) susceptibility and other chronic pain syndromes (CPS) such as chronic widespread pain, irritable bowel syndrome and pelvic pain, may share common heritable factors. Previously, we showed that DE patients describing more severe symptoms tended to report features of neuropathic ocular pain (NOP). We hypothesize that patients with a greater number of CPS would have a different DE phenotype compared to those with fewer CPS. We recruited a cohort of 154 DE patients from the Miami Veterans Affairs Hospital and defined high and low CPS groups by cluster analysis. In addition to worse non-ocular pain complaints and higher PTSD and depression scores (Ppain assessed via 3 different pain scales (Ppain disorder, and that shared mechanistic factors may underlie vulnerability to some forms of DE and other comorbid CPS.

Placebo effects have been reported in patients with chronic neuropathic pain. Expected pain levels and positive emotions are involved in the observed pain relief, but the underlying neurobiology is largely unknown. Patients with neuropathic pain are highly motivated for pain relief, and as motivational factors such as expectations of reward, as well as pain processing in itself, are related to the dopaminergic system, it can be speculated that dopamine release contributes to placebo effects in neuropathic pain. Nineteen patients with neuropathic pain after thoracic surgery were tested during a placebo intervention consisting of open and hidden applications of the pain-relieving agent lidocaine (2 mL) and no treatment. The dopamine antagonist haloperidol (2 mg) and the agonist levodopa/carbidopa (100/25 mg) were administered to test the involvement of dopamine. Expected pain levels, desire for pain relief, and ongoing and evoked pain were assessed on mechanical visual analog scales (0-10). Significant placebo effects on ongoing (P ≤ 0.003) and evoked (P ≤ 0.002) pain were observed. Expectancy and desire accounted for up to 41.2% and 71.5% of the variance in ongoing and evoked pain, respectively, after the open application of lidocaine. We found no evidence for an effect of haloperidol and levodopa/carbidopa on neuropathic pain levels (P = 0.071-0.963). Dopamine seemed to influence the levels of expectancy and desire, yet there was no evidence for indirect or interaction effects on the placebo effect. This is the first study to suggest that dopamine does not contribute to placebo effects in chronic neuropathic pain.

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.

To investigate the relationship between omentin-1 levels and painful temporomandibular disorders (TMD). In a case-control design, chronic painful TMD cases (n = 90) and TMD-free controls (n = 54) were selected from participants in the multisite OPPERA study (Orofacial Pain: Prospective Evaluation and Risk Assessment). Painful TMD case status was determined by examination using established Research Diagnostic Criteria for TMD (RDC/TMD). Levels of omentin-1 in stored blood plasma samples were measured by using an enzyme linked immunosorbent assay. Binary logistic regression was used to calculate the odds ratios (ORs) and 95% confidence limits (CLs) for the association between omentin-1 and painful TMD. Models were adjusted for study site, age, sex, and body mass index. The unadjusted association between omentin-1 and chronic painful TMD was statistically nonsignificant (P = .072). Following adjustment for covariates, odds of TMD pain decreased 36% per standard deviation increase in circulating omentin-1 (adjusted OR = 0.64; 95% CL: 0.43, 0.96; P = .031). Circulating levels of omentin-1 were significantly lower in painful TMD cases than controls, suggesting that TMD pain is mediated by inflammatory pathways.

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.

This study investigated school self-efficacy and sense of school membership (collectively "school self-concept") as potential influences on impaired school function among adolescents with chronic pain, including comparison of adolescents with primary pain to those with disease-based pain and pain-free peers. In all, 264 adolescents (12-17 years old) with primary pain conditions, juvenile idiopathic arthritis, or no pain completed measures of functional disability, school functioning, pain characteristics, and school self-concept, the Self-Efficacy Questionnaire for School Situations (SEQ-SS), and Psychological Sense of School Membership (PSSM). Both the SEQ-SS and PSSM demonstrated reliability and some validity, with the SEQ-SS more strongly supported. As a group, adolescents with primary pain conditions reported poorer school self-concept. School self-efficacy, but not school belongingness, predicted school functioning later in the school year. School self-concept, especially as assessed with the SEQ-SS, is relevant and important to assess when addressing school functioning in youth with chronic pain. © The Author 2017.

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.

Current developments in chronic pain research are changing the focus in the study of pain-emotion relations from the identification of general patterns to the study of dynamic and context-related interactions manifesting both within and between individuals. This shift towards understanding variation

This study used Q-methodology to explore justice-related accounts of chronic pain. Eighty participants completed the Q-sorting procedure (33 chronic pain sufferers and 47 non-pain sufferers). Analysis revealed five main factors. Three factors blame: society for poor medical and interpersonal treatment; the chronic pain sufferer for indulging in self-pity and unempathic healthcare workers for ignoring patients. A fourth factor acknowledges the unfairness of pain and encourages self-reliance. The fifth factor rejects injustice in the chronic pain discourse. Overall, there is a shared view that chronic pain brings unfair treatment, disrespect and a de-legitimization of pain. Future research ideas are suggested.

Insufficient evidence exists to compare widespread pain (WP), pain sensibility, and psychological factors that occur in patients presenting with chronic neck pain (CNP) or a combination of temporomandibular disorder (TMD) and other complaints. The present study compared the pain sensibility and psychological factors of subjects with CNP with those with TMD + CNP. Cross-sectional study. Local community. A nonprobabilistic convenience sample of 86 persons with CNP or TMD was recruited into three groups: CNP, TMD with myofascial pain in masticatory muscles with cocomitant CNP (TMD + CNP), and asymptomatic control groups consisted of 27, 29, and 30 participants, respectively. Participants underwent a clinical examination to evaluate WP with computerized assessment based on the pain drawing, pressure pain thresholds (PPT), and psychological factors, which were evaluated using the pain catastrophizing scale (PCS) and the state-trait anxiety inventory (STAI). Statistically significant differences were observed between participants with CNP and TMD + CNP for WP (t = -2.80, P < 0.01, d = -1.06). Post hoc analyses only revealed significant differences between TMD + CNP participants and asymptomatic controls for PPT at extratrigeminal areas. Pearson correlation analyses showed a moderate positive association between symptomatic groups within the WP and STAI ( P < 0.05) and a moderate negative association between PCS and PPT ( P < 0.05) at the right tibialis muscle. TMD + CNP participants had more areas of pain and also showed widespread pain hyperalgesia. Both groups of participants had psychological factors positively associated with STAI and WP; further, PCS and the PPT at the extratrigeminal region were negatively associated with each other in both groups, except for the left tibialis in the TMD + CNP group. © 2016 American Academy of Pain Medicine.

Background: The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the various symptoms and characteristics of chronic pain. Knowledge concerning changes in pain processing ...

Full Text Available Chronic pain is a significant problem among military personnel and a priority of the military health system. The U.S. Army Surgeon General's Pain Management Task Force recommends using telehealth capabilities to enhance pain management. This article describes the development and evaluation of a telehealth intervention (TelePain designed to improve access to pain specialist consultation in the military health system. The study uses a wait-list cluster controlled clinical trial to test: 1 effectiveness of the intervention, and 2 interviews to assess barriers and facilitators of the intervention implementation. The intervention involves a didactic presentation based on the Joint Pain Education Curriculum followed by patient case presentations and multi-disciplinary discussion via videoconference by clinicians working in the military health system. A panel of pain specialists representing pain medicine, internal medicine, anesthesiology, rehabilitation medicine, psychiatry, addiction medicine, health psychology, pharmacology, nursing, and complementary and integrative pain management provide pain management recommendations for each patient case. We use the Pain Assessment Screening Tool and Outcomes Registry (PASTOR to measure patient outcomes, including pain, sleep, fatigue, anxiety, and depression. This article reports some of the challenges and lessons learned during early implementation of the TelePain intervention. Weekly telephone meetings among the multisite research team were instrumental in problem solving, identifying problem areas, and developing solutions. Solutions for recruitment challenges included additional outreach and networking to military health providers, both building on existing relationships and new relationships.

Abnormal endogenous pain modulation was suggested as a potential mechanism for chronic pain, ie, increased pain facilitation and/or impaired pain inhibition underlying symptoms manifestation. Endogenous pain modulation function can be tested using psychophysical methods such as temporal summation of pain (TSP) and conditioned pain modulation (CPM), which assess pain facilitation and inhibition, respectively. Several studies have investigated endogenous pain modulation function in patients with nonparoxysmal orofacial pain (OFP) and reported mixed results. This study aimed to provide, through a qualitative and quantitative synthesis of the available literature, overall estimates for TSP/CPM responses in patients with OFP relative to controls. MEDLINE, Embase, and the Cochrane databases were searched, and references were screened independently by 2 raters. Twenty-six studies were included for qualitative review, and 22 studies were included for meta-analysis. Traditional meta-analysis and robust variance estimation were used to synthesize overall estimates for standardized mean difference. The overall standardized estimate for TSP was 0.30 (95% confidence interval: 0.11-0.49; P = 0.002), with moderate between-study heterogeneity (Q [df = 17] = 41.8, P = 0.001; I = 70.2%). Conditioned pain modulation's estimated overall effect size was large but above the significance threshold (estimate = 1.36; 95% confidence interval: -0.09 to 2.81; P = 0.066), with very large heterogeneity (Q [df = 8] = 108.3, P pain facilitation and trend for pain inhibition impairment in patients with nonparoxysmal OFP.

The aim of this article was to present the ways that nurses can integrate psychological approaches into their management of chronic pain conditions using a biopsychosocial framework. Communication, the importance of the patient-practitioner interaction, the role of education and provision of information, reassurance and reduction of anxiety and the use of coping strategies training in the management of chronic pain are reviewed alongside the key skills of nursing. This is the second part of a two-part article. Part 1 was a discussion of psychosocial factors associated with chronic pain conditions and the psychological approaches used in the management of these conditions. It is identified that key nursing skills often equate to the requirements of the psychological approaches, therefore specific techniques from a cognitive-behavioural framework can be readily applied, integrated and used by nurses in the management of chronic pain conditions. Commonly utilized nursing skills are similar to those required for cognitive-behavioural therapy. It is reasonable to assume therefore that nurses can and should be involved in effectively managing the psychological aspects associated with chronic pain conditions.

Chronic non-cancer pain (CNCP) is a prevalent occurrence and is experienced by adults in their child-rearing years. Communication within the family about parental illness can be formidable, and family members are often uninformed about illness details. To date, there is no research exploring how children and adolescents understand parental chronic pain, a very complex phenomenon, and its related disability. The aim of this study was to develop a substantive theory that describes how adolescents manage the experience of living with a parent suffering with CNCP and environmental factors that help or hinder this process. Grounded theory was used, the focus of which was adolescents' processes of dealing with parental illness in the interpersonal and environmental contexts of their daily lives. A sample of 30 young adults was recruited in northeastern Ohio using theoretical sampling. During open-ended interviews, participants were asked to look back on their adolescence and talk about how they managed living with parental chronic pain. Interview transcripts and field notes were analyzed using constant comparative methods. Six ways of understanding parental chronic pain emerged from the data: noticing something is different, wrestling with not knowing, searching for answers, questioning the validity of pain, developing insight into the complexity of pain, and learning important life lessons. Findings shed light on how adolescents understand and attach meaning and significance to parental chronic pain and disability and serve as the basis for the development of personalized family interventions.

[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.

The sickness certification and return to work (RTW) of people with chronic pain are important health and economic issues for employees, employers, taxpayers and the UK government. The 'fit note' and a national educational programme promoting RTW were introduced in 2010 to curb rising rates of sickness absence. To investigate employers' and employees' experiences of managing RTW when someone has taken sick leave for chronic pain and to explore the perceived efficacy of the fit note. A qualitative study, comprising semi-structured interviews with employers who had managed sick leave cases and employees who had experienced sick leave for chronic pain. Interviews were recorded, transcribed and the data analysed using constructivist grounded theory principles. Five themes were elicited. Firstly, frequent enquiry after health status was seen as intrusive by some employees but part of good practice by employers and acknowledging this difference was useful. Secondly, being able to trust employees due to their performance track record was helpful for employers when dealing with complex chronic pain conditions. Thirdly, feeling valued increased employees' motivation to RTW. Fourthly, guidelines about maintaining contact with absent employees were useful if used flexibly. Finally, both parties valued the fit note for its positive language, interrogative format and biomedical authority. The fit note was perceived to be helpful if used in combination with other strategies for managing sick leave and RTW for people with chronic pain. These strategies may be applicable to other fluctuating, long-term conditions with medically unexplained elements.

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.

There is increasing recognition that many if not most common chronic pain conditions are heterogeneous with a high degree of overlap or coprevalence of other common pain conditions along with influences from biopsychosocial factors. At present, very little attention is given to the high degree of overlap of many common pain conditions when recruiting for clinical trials. As such, many if not most patients enrolled into clinical studies are not representative of most chronic pain patients. The failure to account for the heterogeneous and overlapping nature of most common pain conditions may result in treatment responses of small effect size when these treatments are administered to patients with chronic overlapping pain conditions (COPCs) represented in the general population. In this brief review we describe the concept of COPCs and the putative mechanisms underlying COPCs. Finally, we present a series of recommendations that will advance our understanding of COPCs. This brief review describes the concept of COPCs. A mechanism-based heuristic model is presented and current knowledge and evidence for COPCs are presented. Finally, a set of recommendations is provided to advance our understanding of COPCs. Copyright © 2016 American Pain Society. Published by Elsevier Inc. All rights reserved.

Chronic pain is frequently associated with hypersensitivity of the nervous system, and drugs that increase central inhibition are therefore a potentially effective treatment. Benzodiazepines are potent modulators of GABAergic neurotransmission and are known to exert antihyperalgesic effects in rodents, but translation into patients are lacking. This study investigates the effect of the benzodiazepine clobazam in chronic low-back pain in humans. The aim of this study is to explore the effect of GABA modulation on chronic low-back pain and on quantitative sensory tests. In this double-blind cross-over study, 49 patients with chronic low-back pain received a single oral dose of clobazam 20 mg or active placebo tolterodine 1 mg. Pain intensity on the 0-10 numeric rating scale and quantitative sensory tests were assessed during 2 h after drug intake. Pain intensity in the supine position was significantly reduced by clobazam compared to active placebo (60 min: 2.9 vs. 3.5, p = 0.008; 90 min: 2.7 vs. 3.3, p = 0.024; 120 min: 2.4 vs. 3.1, p = 0.005). Pain intensity in the sitting position was not significantly different between groups. No effects on quantitative sensory tests were observed. This study suggests that clobazam has an analgesic effect in patients with chronic low-back pain. Muscle relaxation or sedation may have contributed to the effect. Development of substances devoid of these side effects would offer the potential to further investigate the antihyperalgesic action of GABAergic compounds. Modulation of GABAergic pain-inhibitory pathways may be a potential future therapeutic target. © 2017 European Pain Federation - EFIC®.

The symptoms of posttraumatic stress disorder (PTSD) and chronic pain are thought to interact to increase the severity and impact of both conditions, but the mechanisms by which they interact remain unclear. This study examines the relationship between PTSD and chronic pain and whether indices of Psychological Flexibility mediate the relationship between these 2 conditions. Standardized self-report measures of PTSD, pain severity, pain interference, depression, and psychological flexibility (pain-related acceptance, committed action, cognitive fusion, and values-based action) were obtained from 315 people seeking treatment for chronic pain who also reported at least 1 traumatic experience. People seeking treatment for chronic pain and reporting symptoms consistent with a current diagnosis of PTSD had significantly higher levels of pain severity, pain interference, depression, and cognitive fusion and lower levels of pain-related acceptance and committed action than those reporting symptoms below the diagnostic threshold for PTSD. Pain-related acceptance, committed action, cognitive fusion, and depression mediated the relationship between PTSD and pain severity/interference, with pain-related acceptance being the strongest mediator from the Psychological Flexibility model. Processes from the Psychological Flexibility model were identified as mediators of the relationship between PTSD and chronic pain in people seeking treatment for chronic pain. The Psychological Flexibility model may be useful as an overarching model to help understand the relationship between PTSD and chronic pain. It is possible that targeting pain-related acceptance, committed action, and cognitive fusion (among other processes) in the treatment of chronic pain may produce corresponding improvements in comorbid symptoms of PTSD when these are present and may reduce impacts of PTSD on outcomes of chronic pain. Conversely, targeting of these processes in the treatment of PTSD may produce similar

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...

This project was designed to test the feasibility and effectiveness of acupuncture therapy given in a group setting for chronic pain. Nonrandomized, repeated measures quasi-experimental trial. Care was delivered in a primary care clinic waiting area after clinic hours. Included were primary care patients (≥18 years old) with chronic pain of the neck, back, shoulder, or osteoarthritis of any site of at least three months' duration. Subjects received eight weekly acupuncture therapy sessions in a group setting. Acupuncture therapy included a combination of palpation, acupuncture needling, Tui na, Gua sha, and auricular treatment. Baseline pain levels were established in a two- to four-week run-in; assessment of the intervention impact on pain intensity, mood, and functional status were made at the end of the treatment period (eight weeks) and 16 weeks after completion of intervention (24 weeks). Of the total 113 participants recruited for the trial, 96 completed the 24-week protocol. We found a statistically and clinically significant decrease in pain severity, pain interference, and depression in our study population. There were no serious adverse events. Acupuncture therapy offered in the group setting was effective in reducing pain severity, pain interference, and depression in patients with chronic neck, back, or shoulder pain or osteoarthritis. Benefit persisted through the 24-week measure despite no additional treatment. This finding has potentially important implications for improving access to effective acupuncture treatment for patients with limited financial resources. © 2017 American Academy of Pain Medicine.

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.

To describe interventions used by older adults with benign chronic pain. Qualitative study with 25 older adults with benign chronic pain, inhabitants of the cities of Medellín and Bogotá. The technique used to collect information was in-depth interview. The analysis was made using the tools of the theory based on the guidelines of Strauss and Corbin. Using open, axial and selective coding, the constant comparison method allowed the identification of categories and subcategories and simultaneously memos and diagrams were made to reach theoretical saturation. A number of categories were found in this study, suggesting interventions used by the elderly to address chronic pain. They started looking at a number of options such as: taking medication, self-prescribing, feeling fear of taking pills, identifying the damage caused by drugs, using hot water, staying still, taking right postures, walking and exercising, using attachments that help them and making home remedies; all of them become alternatives that can cause pain relief. The study allowed describing interventions that older adults use to mitigate their pain. This ranged from pharmacological to non-pharmacological interventions, as simple as posture, cold, heat, massage or distractions among others, which play an important role in pain relief. Knowing these interventions helps healthcare professionals consider care options different to medication intake, proposing strategies that are easily accessible and can operate at the time to address a patient with chronic pain.

Neuropathic pain is a complex, chronic, and disabling condition that has physical, functional, and psychosocial repercussions. Although the estimated prevalence of neuropathic pain in the general population ranges from 1.5% to 8%, neuropathic pain is frequently underdiagnosed and undertreated. The aims of this study were to examine the experience of patients treated with spinal cord stimulation as a pain-relieving treatment and how this may influence the patient's ability to participate in everyday life activities. A qualitative approach based on seven telephone interviews was performed. The participants were recruited from a university hospital in Norway, and all used spinal cord stimulation as a pain-relieving treatment. Qualitative content analysis was used. Two thematic findings emerged: (1) pain relief with spinal cord stimulation as a complex and individual experience and (2) challenges in adaptations in everyday life with spinal cord stimulation. Findings indicate that spinal cord stimulation can offer pain relief that can help patients achieve a meaningful life despite chronic pain. Spinal cord stimulation also may have disadvantages that should be considered before offering this treatment. It seems evident that extended information needs about working mechanism of SCS and precautions as well as follow-up are required to meet unexpected challenges in adaptation. Here the nurse has an important role when informing and following this patient group. Copyright © 2014 American Society for Pain Management Nursing. Published by Elsevier Inc. All rights reserved.

Pain is a primary symptom driving patients to seek physical therapy, and its attenuation commonly defines a successful outcome. A large body of evidence is dedicated to elucidating the relationship between chronic stress and pain; however, stress is rarely addressed in pain rehabilitation. A physiologic stress response may be evoked by fear or perceived threat to safety, status, or well-being and elicits the secretion of sympathetic catecholamines (epinephrine and norepinepherine) and neuroendocrine hormones (cortisol) to promote survival and motivate success. Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also may facilitate the consolidation of fear-based memories for future survival and avoidance of danger. Although short-term stress may be adaptive, maladaptive responses (eg, magnification, rumination, helplessness) to pain or non-pain-related stressors may intensify cortisol secretion and condition a sensitized physiologic stress response that is readily recruited. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain. Stress may be unavoidable in life, and challenges are inherent to success; however, humans have the capability to modify what they perceive as stressful and how they respond to it. Exaggerated psychological responses (eg, catastrophizing) following maladaptive cognitive appraisals of potential stressors as threatening may exacerbate cortisol secretion and facilitate the consolidation of fear-based memories of pain or non-pain-related stressors; however, coping, cognitive reappraisal, or confrontation of stressors may minimize cortisol secretion and prevent chronic, recurrent pain. Given the parallel mechanisms underlying the physiologic effects of a maladaptive response to pain and non-pain-related stressors, physical therapists should consider screening for non-pain-related stress to
Full Text Available Background. Pediatric chronic pain often emerges in adolescence and cooccurs with internalizing mental health issues and sleep impairments. Emerging evidence suggests that sleep problems may precede the onset of chronic pain as well as anxiety and depression. Studies conducted in pediatric populations with pain-related chronic illnesses suggest that internalizing mental health symptoms may mediate the sleep-pain relationship; however, this has not been examined in youth with primary pain disorders. Objective. To examine whether anxiety and depressive symptoms mediated relationships between sleep quality and pain outcomes among youth with chronic pain. Methods. Participants included 147 youth (66.7% female aged 8–18 years who were referred to a tertiary-level chronic pain program. At intake, the youth completed psychometrically sound measures of sleep quality, pain intensity, pain interference, and anxiety and depressive symptoms. Results. As hypothesized, poor sleep quality was associated with increased pain intensity and pain interference, and anxiety and depressive symptoms mediated these sleep-pain relationships. Discussion. For youth with chronic pain, poor sleep quality may worsen pain through alterations in mood and anxiety; however, prospective research using objective measures is needed. Future research should examine whether targeting sleep and internalizing mental health symptoms in treatments improve pain outcomes in these youth.
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.

Abstract The timing of surgery for painful chronic pancreatitis (CP) may affect outcomes. Clinical course, Izbicki pain scores, and pancreatic function were retrospectively compared and analyzed between patients undergoing either early or late surgery (pancreatic mass +/− ductal dilatation (47% vs 27%, P insufficiency (60% vs 72%, P = .034); there were no other significant differences. The early group had longer hospital stay (14.4 vs 12.2 days, P = .009), but no difference in complications. Significantly greater pain relief followed early surgery (complete 69% vs 47%, partial 22% vs 37%, none 8% vs 16%, P = .01) with lower rates of exocrine (60% vs 80%, P = .005) and endocrine insufficiency (36% vs 53%, P = .033). Our data indicate that early surgery results in higher rates of pain relief and pancreatic sufficiency than late surgery for chronic pancreatitis patients. Frey and Berne procedures showed better results than other surgical procedures. PMID:29742705

To evaluate the efficacy of transcutaneous electrical neurostimulation (TENS) in patients with chronic low back pain (LBP). Prospective, randomized, multicentre, single-blind study. Twenty-one French pain centres. Two hundred thirty-six consecutive adult patients consulting for chronic LBP, with or without radicular pain (mean age ± standard deviation: 53 ± 13 years; range: 28-86 years). Patients were randomly assigned to receive either active (n = 117) or sham (n = 119) TENS in four 1-h daily treatment sessions for 3 months. The primary outcome measured was improvement of functional status at 6 weeks (Roland-Morris Disability Questionnaire). Secondary outcome measures were improvement of functional status at 3 months, pain relief (weekly visual analogue scale assessments), positive functional repercussions of pain levels on quality of life, a diminution of the use of analgesic and anti-inflammatory medication, satisfaction with the overall treatment strategy and compliance. Functional status did not differ between the groups, whether at 6 weeks or 3 months (p = 0.351 at 6 weeks). A significant improvement between the first and last visual analogue scale assessments was observed in patients with either lumbar pain alone or lumbar and radicular pain treated with active TENS. Other outcome measures did not differ significantly between the two groups. There was no functional benefit of TENS in the treatment of patients with chronic LBP. © 2011 European Federation of International Association for the Study of Pain Chapters.

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.

The aim of this study was to assess the incidence of chronic pelvic pain in women after placement of Essure® microinserts. This was a case series study at the hysteroscopy unit in a teaching hospital. We included 4,274 patients undergoing permanent sterilisation with Essure® microinserts from January 2005 to December 2011. Essure devices were removed in all patients reporting pelvic pain after insertion. All data were collected from the hysteroscopy unit database with later review of medical records in cases of chronic pelvic pain and a telephone survey after microinsert removal. Main outcome measures were: grade of procedure difficulty perceived by the surgeon; tolerance described by the patient after placement; the need for analgesics during or immediately after the procedure; side-effects; average time between device placement and the onset of symptoms; time between device placement and removal; technique for device removal and any symptoms thereafter. A total of seven women (0.16%) presented with chronic pelvic pain requiring microinsert removal, with four classifying the pain perceived during the procedure as medium-high. Six patients did not require analgesics after the procedure and a vasovagal syndrome requiring intravenous analgesia and monitoring occurred in only one case. Six women reported pain immediately after the procedure, with a mean time between placement and removal of 29.4 months. In all cases, the symptoms disappeared after Essure removal. We conclude that the development of chronic pelvic pain is very uncommon after placement of Essure microinserts. Removal of these devices usually improves the pain.

To evaluate the evidence for the effectiveness of neuroscience education (NE) for pain, disability, anxiety, and stress in chronic musculoskeletal (MSK) pain. Systematic searches were conducted on Biomed Central, BMJ.com, CINAHL, the Cochrane Library, NLM Central Gateway, OVID, ProQuest (Digital Dissertations), PsycInfo, PubMed/Medline, ScienceDirect, and Web of Science. Secondary searching (PEARLing) was undertaken, whereby reference lists of the selected articles were reviewed for additional references not identified in the primary search. All experimental studies including randomized controlled trials (RCTs), nonrandomized clinical trials, and case series evaluating the effect of NE on pain, disability, anxiety, and stress for chronic MSK pain were considered for inclusion. Additional limitations: studies published in English, published within the last 10 years, and patients older than 18 years. No limitations were set on specific outcome measures of pain, disability, anxiety, and stress. Data were extracted using the participants, interventions, comparison, and outcomes (PICO) approach. Methodological quality was assessed by 2 reviewers using the Critical Review Form-Quantitative Studies. This review includes 8 studies comprising 6 high-quality RCTs, 1 pseudo-RCT, and 1 comparative study involving 401 subjects. Most articles were of good quality, with no studies rated as poor or fair. Heterogeneity across the studies with respect to participants, interventions evaluated, and outcome measures used prevented meta-analyses. Narrative synthesis of results, based on effect size, established compelling evidence that NE may be effective in reducing pain ratings, increasing function, addressing catastrophization, and improving movement in chronic MSK pain. For chronic MSK pain disorders, there is compelling evidence that an educational strategy addressing neurophysiology and neurobiology of pain can have a positive effect on pain, disability, catastrophization, and

A large number of treatments were used for patients with chronic low back pain. Frequent episodes have been reported very high. Although balneotherapy was found effective in this disease, there are not well-designed studies. We aimed to determine the effectiveness of balneotherapy versus physical therapy in patients with chronic low back pain. Exercise was added to both treatment programs. Sixty patients with chronic low back pain were randomly divided into two groups. Physical modalities plus exercise were applied to group 1, and group 2 was received balneotherapy plus exercise for ten sessions. The following parameters were measured: visual analogue scale at rest and movement for pain, paracetamol dose, manual muscle test for lumber muscles, modified Schoeber' test, Oswestry disability index, and Short-Form 36 at the beginning and end of the therapies and at the 3 months follow-up. The statistical analyses were performed using the SPSS 10.0 program. Both groups achieved significant improvements within themselves. But balneotherapy groups were improved at back extensor muscle test (P Balneotherapy combined with exercise therapy had advantages than therapy with physical modalities plus exercise in improving quality of life and flexibility of patients with chronic low back pain.

Acupuncture is now recommended for several chronic pain conditions. Despite supportive evidence of its effectiveness, this ancient approach is often misunderstood, and may still be underused in mainstream practice. A critical review on its effectiveness and practice integration, and mechanisms of action is essential to the medical community that is continuing to seek nonopioid therapies for chronic pain. Mounting evidence supports the effectiveness of acupuncture to treat chronic low back, neck, shoulder, and knee pain, as well as headaches. Additional data are emerging that support the use of acupuncture as an adjunct or alternative to opioids, and in perioperative settings. Findings related to its mechanisms of action include transient receptor potential cation channel vanilloid 1 activation in the periphery, microglial suppression in the cerebral cortex and spinal cord, and regulation of cytokines and other key inflammatory factors in the spinal cord. Incremental integration of acupuncture into pain medicine practices and training programmes continues to grow. Acupuncture is effective, safe, and cost-effective for treating several chronic pain conditions when performed by well-trained healthcare professionals. Further studies on its use as an adjunct or alternative to opioids, and in perioperative settings are needed.

Chronic back pain is among the most common patient complaints. Its prevalence and impact have spawned a rapidly expanding range of tests and treatments. Some of these have become widely used for indications that are not well validated, leading to uncertainty about efficacy and safety, increasing complication rates, and marketing abuses. Recent studies document a 629% increase in Medicare expenditures for epidural steroid injections; a 423% increase in expenditures for opioids for back pain; a 307% increase in the number of lumbar magnetic resonance images among Medicare beneficiaries; and a 220% increase in spinal fusion surgery rates. The limited studies available suggest that these increases have not been accompanied by population-level improvements in patient outcomes or disability rates. We suggest a need for a better understanding of the basic science of pain mechanisms, more rigorous and independent trials of many treatments, a stronger regulatory stance toward approval and post-marketing surveillance of new drugs and devices for chronic pain, and a chronic disease model for managing chronic back pain.

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.

Study Design Controlled laboratory study, case-control design. Objective To evaluate spine kinematics and gait characteristics in people with nonspecific chronic neck pain. Background People with chronic neck pain present with a number of sensorimotor and biomechanical alterations, yet little is known about the influence of neck pain on gait and motions of the spine during gait. Methods People with chronic nonspecific neck pain and age- and sex-matched asymptomatic controls walked on a treadmill at 3 different speeds (self-selected, 3 km/h, and 5 km/h), either with their head in a neutral position or rotated 30°. Tridimensional motion capture was employed to quantify body kinematics. Neck and trunk rotations were derived from the difference between the transverse plane component of the head and thorax and thorax and pelvis angles to provide an indication of neck and trunk rotation during gait. Results Overall, the patient group showed shorter stride length compared to the control group (Pneck pain showed smaller trunk rotations (Pneck pain walk with reduced trunk rotation, especially when challenged by walking with their head positioned in rotation. Reduced rotation of the trunk during gait may have long-term consequences on spinal health. J Orthop Sports Phys Ther 2017;47(4):268-277. Epub 3 Feb 2017. doi:10.2519/jospt.2017.6768.

Complementary and integrative medicine (CIM) encompasses both Western-style medicine and complementary health approaches as a new combined approach to treat a variety of clinical conditions. Chronic pain is the leading indication for use of CIM, and about 33% of adults and 12% of children in the US have used it in this context. Although advances have been made in treatments for chronic pain, it remains inadequately controlled for many people. Adverse effects and complications of analgesic drugs, such as addiction, kidney failure, and gastrointestinal bleeding, also limit their use. CIM offers a multimodality treatment approach that can tackle the multidimensional nature of pain with fewer or no serious adverse effects. This review focuses on the use of CIM in three conditions with a high incidence of chronic pain: back pain, neck pain, and rheumatoid arthritis. It summarizes research on the mechanisms of action and clinical studies on the efficacy of commonly used CIM modalities such as acupuncture, mind-body system, dietary interventions and fasting, and herbal medicine and nutrients.

Full Text Available Antiepileptic drugs (AEDs are extensively used worldwide to treat a wide range of disorders other than epilepsy, such as neuropathic pain, migraine and bipolar disorder. Due to this situation more than 20 new third-generation AEDs have been introduced in the market recently. The future design of new AEDs must also have potential to help in the non-epileptic disorders. The wide acceptance of second generation AEDs for the management of various Non-epileptic disorders has caused the emergence of generics in the market. The wide use of approved AEDs outside epilepsy is based on both economic and scientific reasons. Bipolar disorders, migraine prophylaxis, fibromyalgia and neuropathic pain represent the most attractive indication expansion opportunities for anticonvulsant developers, providing blockbuster revenues. Strong growth in non-epilepsy conditions will see Pfizer’s Lyrica become the market leading brand by 2018. In this review we mainly focus on the current status of new AEDs in the treatment of chronic pain and migraine prophylaxis. AEDs have a strong analgesic potential and this is demonstrated by the wide use of carbamazepine in trigeminal neuralgia and sodium valproate in migraine prophylaxis. At present, data on the new AEDs for non-epileptic conditions are inconclusive. Not all AEDs are effective in the management of neuropathic pain and migraine. Only those AEDs whose mechanisms of action are match with pathophysiology of the disease, have potential to show efficacy in non-epileptic disorder. For this better understanding of the pathophysiology of the disease and mechanisms of action of new AEDs are essential requirement before initiating pre-clinical and clinical trials. Many new AEDs show good results in the animal model and open-label studies but fail to provide strong evidence at randomized, placebo-controlled trials. The final decision regarding the clinical efficacy of the particular AEDs in a specific non-epileptic disorder

When assessing women with chronic vulvar pain, women's health physical therapists search for comorbid mechanical components (including musculoskeletal, fascial, and visceral) and other disorders that may contribute to or be caused by chronic vulvar pain (CVP). Pelvic floor hypertonicity is a key perpetuating factor for CVP. Comprehensive physical therapy evaluation and suggested physical therapy interventions are described. Anatomy of the pelvis, common evaluative findings, and specifics for pelvic floor muscle rehabilitation are presented. Normalization of pelvic floor muscle function contributes to the reduction of CVP. Successful treatment includes the identification and treatment of co-existing physical abnormalities throughout the trunk and pelvis. © 2010 Wiley Periodicals, Inc.

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.

We downgraded the quality of the evidence by three levels to very low because there was no evidence to support or refute. Secondary outcomesAll studies measured adverse events, with very few reported (11 out of 272 participants). All but one adverse event occurred in the active treatment groups (amitriptyline, citalopram, and gabapentin). Adverse events in all studies, across active treatment and comparator groups, were considered to be a mild reaction, such as nausea, dizziness, drowsiness, tiredness, and abdominal discomfort (very low-quality evidence).There were also very few withdrawals due to adverse events, again all but one from the active treatment groups (very low-quality evidence).No serious adverse events were reported across any of the studies (very low-quality evidence).There were few or no data for our remaining secondary outcomes (very low-quality evidence).We rated the overall quality of the evidence (GRADE rating) for these secondary outcomes as very low. We downgraded the quality of the evidence by three levels to very low due to too few data and the fact that the number of events was too small to be meaningful. We identified only a small number of studies with small numbers of participants and insufficient data for analysis.As we could undertake no meta-analysis, we are unable to comment about efficacy or harm from the use of antidepressants to treat chronic non-cancer pain in children and adolescents.

Pain continues to be a serious health care concern in the United States. Patients with chronic pain experience the impact of the disease throughout their lives including their social interactions, family relationships, and in many cases economic productivity. Multiple surveys have found that many pharmacists hold misconceptions regarding opioids, pain disease states, and their understandings of current regulations. Multiple barriers affect the ability of pharmacists to deliver care to patients' prescribed opioid therapy. Inadequate communication between health care professionals and patients is one of the hurdles, which prevents quality care. Increased communication between health care providers including access to health information is one step, which is crucial to improving provision of pharmacotherapy. Finally, the quality of educational opportunities relative to opioids and pain management specifically for pharmacists needs to be increased, and consideration needs to be given for making appropriate pain management education mandatory.

Pain and reward are opponent, interacting processes. Such interactions are enabled by neuroanatomical and neurochemical overlaps of brain systems that process pain and reward. Cerebral processing of hedonic ('liking') and motivational ('wanting') aspects of reward can be separated: the orbitofrontal cortex and opioids play an important role for the hedonic experience, and the ventral striatum and dopamine predominantly process motivation for reward. Supported by neuroimaging studies, we present here the hypothesis that the orbitofrontal cortex and opioids are responsible for pain modulation by hedonic experience, while the ventral striatum and dopamine mediate motivational effects on pain. A rewarding stimulus that appears to be particularly important in the context of pain is pain relief. Further, reward, including pain relief, leads to operant learning, which can affect pain sensitivity. Indirect evidence points at brain mechanisms that might underlie pain relief as a reward and related operant learning but studies are scarce. Investigating the cerebral systems underlying pain-reward interactions as well as related operant learning holds the potential of better understanding mechanisms that contribute to the development and maintenance of chronic pain, as detailed in the last section of this review.

Chronic pain can be associated with movement abnormalities. The primary motor cortex (M1) has an essential role in the formulation and execution of movement. A number of changes in M1 function have been reported in studies of people with chronic pain. This review systematically evaluated the evidence for altered M1 structure, organization, and function in people with chronic pain of neuropathic and non-neuropathic origin. Database searches were conducted and a modified STrengthening the Reporting of OBservational studies in Epidemiology checklist was used to assess the methodological quality of included studies. Meta-analyses, including preplanned subgroup analyses on the basis of condition were performed where possible. Sixty-seven studies (2,290 participants) using various neurophysiological measures were included. There is conflicting evidence of altered M1 structure, organization, and function for neuropathic and non-neuropathic pain conditions. Meta-analyses provided evidence of increased M1 long-interval intracortical inhibition in chronic pain populations. For most measures, the evidence of M1 changes in chronic pain populations is inconclusive. This review synthesizes the evidence of altered M1 structure, organization, and function in chronic pain populations. For most measures, M1 changes are inconsistent between studies and more research with larger samples and rigorous methodology is required to elucidate M1 changes in chronic pain populations.

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

Back pain, the most prevalent musculoskeletal chronic pain condition, is usually treated with analgesic medications of questionable efficacy and frequent occurrence of adverse side effects. The objective was to determine the effectiveness of the ActiPatch medical devices in reducing chronic back pain, document medication related adverse side effects and establish their impact on quality of life. Upon completing a 7-day trial, subjects were contacted via email with an assessment form using the Constant Contact email program. A total of 1394 responses were collected from subjects who used the device for back pain. Medication adverse effects are common and impact quality of life in the lay population. ActiPatch is an effective intervention for the majority of subjects for treating chronic back pain, although this requires further investigation in randomized clinical trials.

Insomnia is frequently experienced by patients suffering from chronic musculoskeletal disorders but is often seen as simply a symptom of pain or depression and not as an independent disorder. Compared with those who experience only chronic pain, patients with both chronic pain and insomnia report higher pain intensity, more depressive symptoms, and greater distress. However, insomnia has not yet been systematically studied in a chronic musculoskeletal pain with disability population. This study assessed the prevalence and severity of patient-reported insomnia, as well as the relationship among insomnia, pain intensity, and depressive symptoms, in a chronic musculoskeletal pain with disability population. This was a retrospective study of prospectively captured data. A consecutive cohort of 326 chronic musculoskeletal pain with disability patients (85% with spinal injuries) entered a functional restoration treatment program. All patients signed a consent form to participate in this protocol. Insomnia was assessed with the Insomnia Severity Index, a validated patient-report measure of insomnia symptoms. Four patient groups were formed: no clinically significant insomnia (score, 0-7); subthreshold insomnia (score, 8-14); moderate clinical insomnia (score, 15-21); and severe clinical insomnia (score, 22-28). Three patterns of sleep disturbance were also evaluated: early, middle, and late insomnia. Additional validated psychosocial patient-reported data were collected, including the Pain Visual Analog Scale, the Beck Depression Inventory, the Oswestry Disability Index, and the Pain Disability Questionnaire. Patients completed a standard psychosocial assessment battery on admission to the functional restoration program. The program included a quantitatively directed exercise process in conjunction with a multimodal disability management approach. The four insomnia groups were compared on demographic and psychosocial variables. The shared variances among insomnia

This review is an update of a review published in 2011, itself a major update of previous reviews published in 2005 and 2000, investigating the effects of gabapentin in chronic neuropathic pain (pain due to nerve damage). Antiepileptic drugs are used to manage chronic neuropathic pain and fibromyalgia. To assess the analgesic efficacy and adverse effects of gabapentin in chronic neuropathic pain and fibromyalgia. We identified randomised trials of gabapentin for chronic neuropathic pain or fibromyalgia by searching the databases MEDLINE (1966 to March 2014), EMBASE (1980 to 2014 week 10), and CENTRAL in The Cochrane Library (Issue 3 of 12, 2014). We obtained clinical trial reports and synopses of published and unpublished studies from Internet sources, and searched Clinicaltrials.gov. Searches were run originally in 2011 and the date of the most recent search was 17 March 2014. Randomised, double-blind studies reporting the analgesic and adverse effects of gabapentin in neuropathic pain or fibromyalgia with assessment of pain intensity, pain relief, or both, using validated scales. Participants were adults. Three review authors independently extracted efficacy and adverse event data, examined issues of study quality, and assessed risk of bias. We performed analysis using three tiers of evidence. First tier evidence derived from data meeting current best standards and subject to minimal risk of bias (outcome equivalent to substantial pain intensity reduction, intention-to-treat analysis without imputation for dropouts; at least 200 participants in the comparison, 8 to 12 weeks duration, parallel design), second tier from data that failed to meet one or more of these criteria and were considered at some risk of bias but with adequate numbers in the comparison, and third tier from data involving small numbers of participants that were considered very likely to be biased or used outcomes of limited clinical utility, or both.For efficacy, we calculated the number needed

Virtual reality (VR) technologies have been successfully applied to acute pain interventions and recent reviews have suggested their potential utility in chronic pain. The current review highlights the specific relevance of VR interactive gaming technologies for pain-specific intervention, including their current use across a variety of physical conditions. Using the example of graded-exposure treatment for pain-related fear and disability in chronic low back pain, we discuss ways that VR gaming can be harnessed to optimize existing chronic pain therapies and examine the potential limitations of traditional VR interfaces in the context of chronic pain. We conclude by discussing directions for future research on VR-mediated applications in chronic pain.

The objective of the study was to collect data on the direct and indirect economic cost of chronic pain among patients attending a pain management clinic in Ireland. A tertiary pain management clinic serving a mixed urban and rural area in the West of Ireland. Data were collected from 100 patients using the Client Services Receipt Inventory and focused on direct and indirect costs of chronic pain. Patients were questioned about health service utilization, payment methods, and relevant sociodemographics. Unit costs were multiplied by resource use data to obtain full costs. Cost drivers were then estimated. Our study showed a cost per patient of US$24,043 over a 12-month period. Over half of this was attributable to wage replacement costs and lost productivity in those unable to work because of pain. Hospital stays and outpatient hospital services were the main drivers for health care utilization costs, together accounting for 63% of the direct medical costs per study participant attending the pain clinic. The cost of chronic pain among intensive service users is significant, and when extrapolated to a population level, these costs represent a very substantial economic burden. Wiley Periodicals, Inc.
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.

Neuropathic pain remains poorly treated for large numbers of patients, and little progress has been made in developing novel classes of analgesics. To redress this issue, ziconotide (Prialt™) was developed and approved as a first-in-class synthetic version of ω-conotoxin MVIIA, a peptide blocker of Ca v 2.2 channels. Unfortunately, the impracticalities of intrathecal delivery, low therapeutic index and severe neurological side effects associated with ziconotide have restricted its use to exceptional circumstances. Ziconotide exhibits no state or use-dependent block of Ca v 2.2 channels; activation state-dependent blockers were hypothesized to circumvent the side effects of state-independent blockers by selectively targeting high-frequency firing of nociceptive neurones in chronic pain states, thus alleviating aberrant pain but not affecting normal sensory transduction. Unfortunately, numerous drugs, including state-dependent calcium channel blockers, have displayed efficacy in preclinical models but have subsequently been disappointing in clinical trials. In recent years, it has become more widely acknowledged that trans-aetiological sensory profiles exist amongst chronic pain patients and may indicate similar underlying mechanisms and drug sensitivities. Heterogeneity amongst patients, a reliance on stimulus-evoked endpoints in preclinical studies and a failure to utilize translatable endpoints, all are likely to have contributed to negative clinical trial results. We provide an overview of how electrophysiological and operant-based assays provide insight into sensory and affective aspects of pain in animal models and how these may relate to chronic pain patients in order to improve the bench-to-bedside translation of calcium channel modulators.

A variety of approaches have been used to develop diagnostic criteria for chronic pain. The published evidence of the reliability and validity of existing diagnostic criteria is limited, and these criteria have typically not been used in clinical practice. The availability of a widely accepted, consistently applied, and evidence-based taxonomy of diagnostic criteria would improve the quality of clinical research on chronic pain and would be of great value in clinical practice. To address the need for evidence-based diagnostic criteria for the major chronic pain conditions, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the US Food and Drug Administration and the American Pain Society (APS) have collaborated on the development of the ACTTION-APS Pain Taxonomy (AAPT). AAPT provides a multidimensional framework that is applied systematically in the development of diagnostic criteria. This article (1) describes the background and rationale for AAPT; (2) presents the AAPT taxonomy and the specific conditions for which diagnostic criteria have been developed (to be published separately); (3) briefly reviews the 5 dimensions that constitute the AAPT multidimensional framework and describes the 7 accompanying articles that discuss these dimensions and other important issues involving AAPT; and (4) provides an overview of next steps, specifically, the general processes by which the initial set of diagnostic criteria (for which the evidence base has been drawn from the literature, systematic reviews, and secondary analyses of existing databases) will undergo additional assessments of reliability and validity. To address the need for evidence-based diagnostic criteria for the major chronic pain conditions, the AAPT provides a multidimensional framework that is applied systematically in the development of diagnostic criteria. The long-term objective of AAPT is to advance

To review systematically and integrate the findings of qualitative research to increase our understanding of patients' experiences of chronic pelvic pain. Chronic pelvic pain is a prevalent pain condition with a high disease burden for men and women. Its multifactorial nature makes it challenging for clinicians and patients. Synthesis of qualitative research using meta-ethnography. Five electronic bibliographic databases from inception until March 2014 supplemented by citation tracking. Of 488 papers retrieved, 32 met the review aim. Central to meta-ethnography is identifying 'concepts' and developing a conceptual model through constant comparison. Concepts are the primary data of meta-ethnography. Two team members read each paper to identify and collaboratively describe the concepts. We next compared concepts across studies and organized them into categories with shared meaning. Finally, we developed a conceptual model, or line of argument, to explain the conceptual categories. Our findings incorporate the following categories into a conceptual model: relentless and overwhelming pain; threat to self; unpredictability, struggle to construct pain as normal or pathological; a culture of secrecy; validation by diagnosis; ambiguous experience of health care; elevation of experiential knowledge and embodiment of knowledge through a community. The innovation of our model is to demonstrate, for the first time, the central struggle to construct 'pathological' vs. 'normal' chronic pelvic pain, a struggle that is exacerbated by a culture of secrecy. More research is needed to explore men's experience and to compare this with women's experience. © 2014 John Wiley & Sons Ltd.

Full Text Available Pain catastrophizing, a pattern of negative cognitive-emotional responses to actual or anticipated pain, maintains chronic pain and undermines response to treatments. Currently, precisely how pain catastrophizing influences pain processing is not well understood. In experimental settings, pain catastrophizing has been associated with amplified pain processing. This study sought to clarify pain processing mechanisms via experimental induction of pain catastrophizing. Forty women with chronic low back pain were assigned in blocks to an experimental condition, either a psychologist-led 10-minute pain catastrophizing induction or a control (10-minute rest period. All participants underwent a baseline round of several quantitative sensory testing (QST tasks, followed by the pain catastrophizing induction or the rest period, and then a second round of the same QST tasks. The catastrophizing induction appeared to increase state pain catastrophizing levels. Changes in QST pain were detected for two of the QST tasks administered, weighted pin pain and mechanical allodynia. Although there is a need to replicate our preliminary results with a larger sample, study findings suggest a potential relationship between induced pain catastrophizing and central sensitization of pain. Clarification of the mechanisms through which catastrophizing affects pain modulatory systems may yield useful clinical insights into the treatment of chronic pain.

The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the various symptoms and characteristics of chronic pain. Knowledge concerning changes in pain processing in LBP remains ambiguous, partly due to the diversity in the LBP population. The purpose of this study is to compare quantitative sensory assessment in different groups of LBP patients with regard to chronicity. Recurrent low back pain (RLBP), mild chronic low back pain (CLBP), and severe CLBP are compared on the one hand with healthy controls (HC), and on the other hand with fibromyalgia (FM) patients, in which abnormal pain processing has previously been reported. Cross-sectional study. Department of Rehabilitation Sciences, Ghent University, Belgium. Twenty-three RLBP, 15 mild CLBP, 16 severe CLBP, 26 FM, and 21 HC participated in this study. Quantitative sensory testing was conducted by manual pressure algometry and computer-controlled cuff algometry. A manual algometer was used to evaluate hyperalgesia as well as temporal summation of pain and a cuff algometer was used to evaluate deep tissue hyperalgesia, the efficacy of the conditioned pain modulation and spatial summation of pain. Pressure pain thresholds by manual algometry were significantly lower in FM compared to HC, RLBP, and severe CLBP. Temporal summation of pain was significantly higher in FM compared to HC and RLBP. Pain tolerance thresholds assessed by cuff algometry were significantly lower in FM compared to HC and RLBP and also in severe CLBP compared to RLBP. No significant differences between groups were found for spatial summation or conditioned pain modulation. No psychosocial issues were taken into account for this

Background and Objectives Factors underlying differential responsiveness to opioid analgesic medications used in chronic pain management are poorly understood. We tested whether individual differences in endogenous opioid inhibition of chronic low back pain were associated with magnitude of acute reductions in back pain ratings following morphine administration. Methods In randomized, counterbalanced order over three sessions, 50 chronic low back pain patients received intravenous naloxone (8mg), morphine (0.08 mg/kg), or placebo. Back pain intensity was rated pre-drug and again after peak drug activity was achieved using the McGill Pain Questionnaire-Short Form (Sensory and Affective subscales, VAS intensity measure). Opioid blockade effect measures to index degree of endogenous opioid inhibition of back pain intensity were derived as the difference between pre-to post-drug changes in pain intensity across placebo and naloxone conditions, with similar morphine responsiveness measures derived across placebo and morphine conditions. Results Morphine significantly reduced back pain compared to placebo (MPQ-Sensory, VAS; P effects of opioid blockade on back pain intensity. However, individual differences in opioid blockade effects were significantly associated with degree of acute morphine-related reductions in back pain on all measures, even after controlling for effects of age, sex, and chronic pain duration (P morphine. Conclusions Morphine appears to provide better acute relief of chronic back pain in individuals with lower natural opioidergic inhibition of chronic pain intensity. Possible implications for personalized medicine are discussed. PMID:24553304

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.

The authors undertook a case-control study of chronic neck pain and whiplash injuries in nine states in the United States to determine whether whiplash injuries contributed significantly to the population of individuals with chronic neck and other spine pain. Four hundred nineteen patients and 246 controls were randomly enrolled. Patients were defined as individuals with chronic neck pain, and controls as those with chronic back pain. The two groups were surveyed for cause of chronic pain as well as demographic information. The two groups were compared using an exposure-odds ratio. Forty-five per cent of the patients attributed their pain to a motor vehicle accident. An OR of 4.0 and 2.1 was calculated for men and women, respectively. Based on the results of the present study, it reasonable to infer that a significant proportion of individuals with chronic neck pain in the general population were originally injured in a motor vehicle accident.

Chronic pain is prevalent, complex and most effectively treated by a multidisciplinary team, particularly if psychosocial issues are dominant. The limited access to and high costs of such services are often prohibitive for the rural patient. We describe the development and 18-month outcomes of a small multidisciplinary chronic pain management program run out of a physician's office in rural Alberta. The multidisciplinary team consisted of a family physician, physiatrist, psychologist, physical therapist, kinesiologist, nurse and dietician. The allied health professionals were involved on a part-time basis. The team triaged referral information and patients underwent either a spine or medical care assessment. Based on the findings of the assessment, the team managed the care of patients using 1 of 4 methods: consultation only, interventional spine care, supervised medication management or full multidisciplinary management. We prospectively and serially recorded self-reported measures of pain and disability for the supervised medication management and full multidisciplinary components of the program. Patients achieved clinically and statistically significant improvements in pain and disability. Successful multidisciplinary chronic pain management services can be provided in a rural setting.

This study was planned to compare of pain, emotional status and disability level in patients with chronic neck pain and low back pain. In this study, fifty patients with chronic low back pain (Group I) and fifty patients with chronic neck pain (Group II) at least 6 months were evaluated. A Visual Analog Scale was used to describe pain intensity. To determine emotional status of the subjects, the Beck Depression Scale was used The Oswestry Disability Index and the Neck Disability Index were used to evaluate disability level. The mean age of the patients with low back pain and neck pain were 39.70 ± 9.71 years, 45.44 ± 10.39 years, respectively. It was not found a significant difference between in low back pain (Group I) and neck pain (Group II) in results of pain intensity (p= 0.286) and pain duration (p= 0.382). It was found a significant difference between group I and group II in results of emotional status (p= 0.000) and disability level (p= 0.000). The emotional status and disability level scores were found highest in patient's with low back pain. Chronic low back pain is affect in patients than chronic neck pain as a emotional status and disability level.

The fear-avoidance model of chronic pain has established avoidance as a predictor of negative outcomes in chronic pain patients. Avoidance, or deliberate attempts to suppress or prevent unwanted experiences (e.g., pain), has been studied extensively, with multiple reviews implicating this behavior as a predictor of disability, physical disuse, and depression. Despite hundreds of studies examining the associations between different components of this model (i.e., catastrophizing, fear, avoidance, depression), the association between fear-avoidance and pain intensity has remained unclear. The present study seeks to clarify this association across samples. The present analyses synthesize the literature (articles from PsycInfo, PubMed, and ProQuest) to determine if fear-avoidance and pain intensity are consistently correlated across studies, samples, and measures. Eligible studies measured pain intensity and fear-avoidance cross-sectionally in chronic pain patients. The search resulted in 118 studies eligible for inclusion. A random-effects model was used to estimate the weighted mean effect size. Comprehensive Meta-Analysis software was used for all analyses. Moderation analyses elucidate the variables that affect the strength of this association. Meta-regression and meta-ANOVA analyses were conducted to examine moderating variables. Moderator variables include demographic characteristics, pain characteristics, study characteristics, and national cultural characteristics (using Hofstede's cultural dimensions). Publication bias was examined using the funnel plot and the p-curve. Results indicate a small-to-moderate positive association between fear-avoidance and pain intensity. The results were stable across characteristics of the sample, including mean age, gender distribution, marital status, and duration of pain. Moderation analyses indicate that the measures utilized and cultural differences affect the strength of this association. Weaker effect sizes were observed

Chronic pain and posttraumatic stress disorder (PTSD) symptoms have been found to co-occur in adults; however, research has not examined this co-occurrence in adolescence, when pediatric chronic pain often first emerges. The aims of this study were to compare the frequency and intensity of PTSD symptoms and stressful life events in cohorts of youth with (n = 95) and without (n = 100) chronic pain and their parents and to determine the association between PTSD symptoms, health-related quality of life, and pain symptoms within the chronic pain sample. All participants completed questionnaire measures through an online survey. Findings revealed that youth with chronic pain and their parents had significantly higher levels of PTSD symptoms as compared with pain-free peers. More youth with chronic pain (32%) and their parents (20%) reported clinically significant elevations in PTSD symptoms than youth without chronic pain (8%) and their parents (1%). Youth with chronic pain also reported a greater number of stressful life events than those without chronic pain, and this was associated with higher PTSD symptoms. Among the chronic pain cohort, higher levels of PTSD symptoms were predictive of worse health-related quality of life and were associated with higher pain intensity, unpleasantness, and interference. Results suggest that elevated PTSD symptoms are common and linked to reduced functioning among youth with chronic pain. Future research is needed to examine PTSD at the diagnostic level and the underlying mechanisms that may explain why this co-occurrence exists.

This study aimed to analyze the experience of working women suffering from chronic musculoskeletal pain, using a qualitative design with a phenomenological approach. The technique drew on in-depth interviews with five working women that presented to the orthopedics and neurosurgery departments of a hospital in Guadalajara, Mexico, with a complaint of musculoskeletal pain for more than six months. The study showed that the women felt rejection, segregation, discrimination, lack of support at the workplace, and feelings of frustration and powerlessness related to their health condition. The women also perceived as a barrier the lack of efficiency in disability proceedings and job reintegration or relocation. Financial and family responsibilities were their main reason for continuing to work despite their chronic musculoskeletal pain.

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.
Full Text Available Holistic medicine seems to be efficient in the treatment of chronic pain in internal organs, especially when the pain has no known cause. It is quite surprising that while chronic pain can be one of the toughest challenges in the biomedical clinic, it is often one of the simplest things to alleviate in the holistic clinic. These pains are regarded as being caused by repressed emotions and are explained as psychosomatic reactions. Using holistic medicine, the patients can often be cured of their suffering when they assume responsibility for the repressed feelings. The holistic process theory of healing states that the return to the natural (pain free state of being is possible whenever the person obtains the resources needed for existential healing. This shift is explained by the related quality of life and life mission theories. The resources needed are “holding” or genuine care in the dimensions of awareness, respect, care, acknowledgment, and acceptance with support and processing in the dimensions of feeling, understanding, and letting go of negative attitudes and beliefs. The preconditions for the holistic healing to take place are “love” and trust. Obtaining the full trust of the patient, therefore, seems to be the biggest challenge of holistic medicine, especially when dealing with a patient in pain.

Patients with an implanted spinal cord stimulation (SCS) system for pain management present an opportunity to study dynamic changes in the pain system in a situation where patients are not stimulated (ie, experiencing severe pain) compared with a situation in which patients have just been stimulated (ie, pain free or greatly reduced pain). The aims of this study were (1) to determine if there are differences in nociceptive withdrawal reflex thresholds (NWR-T) and electrical pain thresholds (EP-T) before and after SCS; and (2) to establish if these differences are related to psychological factors associated with chronic pain. Seventeen volunteers with chronic neuropathic pain participated in the experiment. Electrical stimuli were applied to assess the NWR-T and the EP-T. In addition, psychological factors (ie, pain characteristics, depression, anxiety, and disability indexes) were also recorded. The NWR-T and EP-T were assessed with the SCS system off (at least 8 h before the experiment), and then reassessed 1 hour after the SCS system was turned on. Ongoing pain intensity ratings decreased (P=0.018), whereas the NWR-T increased (P=0.028) after the SCS was turned on, whereas no significant difference was found for EP-T (P=0.324). Psychological factors were significant predictors for EP-T but not for NWR-T. The results of this study suggest that pain relief after SCS is partially mediated by a decrease in the excitability of dorsal horn neurons in the spinal cord.

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 principle aim of this study was to investigate the associations between heat pain (HP) perception, pain catastrophizing, and pain-related anxiety in a heterogenous cohort of community-dwelling adults with chronic pain admitted to a 3-week outpatient pain rehabilitation program. All adults consecutively admitted to an outpatient pain rehabilitation program from July 2009 through January 2011 were eligible for study recruitment (n=574). Upon admission, patients completed the Pain Catastrophizing Scale (PCS), the short version of the Pain Anxiety Symptoms Scale (PASS-20), and HP perception was assessed using a standardized quantitative sensory testing (QST) method of levels. Greater PCS scores were significantly correlated with lower standardized values of HP threshold (HP 0.5) (P=0.006) and tolerance (HP 5) (P=0.003). In a multiple variable model adjusted for demographic and clinical factors known to influence HP perception, every 10-point increase in the PCS was associated with a -0.124 point change in HP 0.5 (P=0.014) and a -0.142 change in HP 5 (P=0.014) indicating that participants with higher PCS scores had lower HP thresholds and tolerances, respectively. Similarly, greater PASS-20 scores significantly correlated with lower standardized values of HP 0.5 and HP 5. In a multiple variable model, every 10-point increase in the PASS-20 was associated with a -0.084 point change in HP 0.5 (P=0.005) and a -0.116 point change in HP 5 (P=0.001) indicating that participants with higher PASS-20 scores had lower HP thresholds and tolerances, respectively. The findings of this study extend the use of a standardized method for assessing HP in a heterogenous sample of adults with chronic pain. Although pain catastrophizing shares significant variance with pain-related anxiety, our findings suggest that either measure would be appropriate for use in future studies that incorporate the QST method of levels.

Total hip arthroplasty (THA) is one of the most successful operations that can restore function and relieve pain. Although a majority of the patients achieve significant pain relief after THA, there are a number of patients that develop chronic pain for unknown reasons. A literature search was performed looking for chronic pain after total hip arthroplasty and stable THA. Major causes of chronic pain include aseptic loosening or infection. However, there is a subset of patients with a stable ...

Chronic pain occurs in as many as 85% of individuals with HIV and is associated with substantial functional impairment. Little guidance is available for HIV providers seeking to address their patients’ chronic pain. We conducted a systematic review to identify clinical trials and observational studies that examined the impact of pharmacologic or non-pharmacologic interventions on pain and/or functional outcomes among HIV-infected individuals with chronic pain in high-development countries. Eleven studies met inclusion criteria and were mostly low or very low quality. Seven examined pharmacologic interventions (gabapentin, pregabalin, capsaicin, analgesics including opioids) and four examined non-pharmacologic interventions (cognitive behavioral therapy, self-hypnosis, smoked cannabis). The only controlled studies with positive results were of capsaicin and cannabis, and had short-term follow-up (≤12 weeks). Among the seven studies of pharmacologic interventions, five had substantial pharmaceutical industry sponsorship. These findings highlight several important gaps in the HIV/chronic pain literature that require further research. PMID:27267445

Available evidence favors the use of pain neuroscience education (PNE) in patients with chronic pain. However, PNE trials are often limited to small sample sizes and, despite the current digital era, the effects of blended-learning PNE (ie, the combination of online digital media with traditional educational methods) have not yet been investigated. The study objective was to examine whether blended-learning PNE is able to improve disability, catastrophizing, kinesiophobia, and illness perceptions. This study was a 2-center, triple-blind randomized controlled trial (participants, statistician, and outcome assessor were masked). The study took place at university hospitals in Ghent and Brussels, Belgium. Participants were 120 people with nonspecific chronic spinal pain (ie, chronic neck pain and low back pain). The intervention was 3 sessions of PNE or biomedically focused back/neck school education (addressing spinal anatomy and physiology). Measurements were self-report questionnaires (Pain Disability Index, Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Illness Perception Questionnaire, and Pain Vigilance and Awareness Questionnaire). None of the treatment groups showed a significant change in the perceived disability (Pain Disability Index) due to pain (mean group difference posteducation: 1.84; 95% CI = -2.80 to 6.47). Significant interaction effects were seen for kinesiophobia and several subscales of the Illness Perception Questionnaire, including negative consequences, cyclical time line, and acute/chronic time line. In-depth analysis revealed that only in the PNE group were these outcomes significantly improved (9% to 17% improvement; 0.37 ≤ Cohen d ≥ 0.86). Effect sizes are small to moderate, which might raise the concern of limited clinical utility; however, changes in kinesiophobia exceed the minimal detectable difference. PNE should not be used as the sole treatment modality but should be combined with other treatment strategies

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

Chronic pain places a burden on individuals and the economy. Although there is evidence for the effectiveness of cognitive-behavior therapy, it is recognized that the effects are limited. Acceptance and Commitment Therapy (ACT), which aims to increase valued action in the presence of pain, has been suggested as an alternative approach. The objective of this review was to determine the clinical effectiveness of ACT for chronic pain in adults when compared with control conditions and other active treatments. The searches of this systematic review were conducted in the Cochrane library, MEDLINE, EMBASE, CINAHL Plus (EBSCO), and PsycINFO. Grey literature, reference list, and reverse citation searches were also completed. Eleven trials were included. ACT was favored over controls (no alternative intervention or treatment as usual). Significant, medium to large effect sizes were found for measures of pain acceptance and psychological flexibility, which are typically considered processes of ACT. Significant small to medium effect sizes were found for measures of functioning, anxiety, and depression. Measures of pain intensity and quality of life were not significantly different than zero. Generally effect sizes were smaller at follow-up. ACT was more clinically effective than controls on a number of outcomes. It is possible that methodological limitations, some of which are common to psychological trials, may have led to overestimated effects. Only a few studies compared ACT to active treatments and while the evidence is promising for ACT in the treatment of chronic pain, further methodologically robust trials are required.

Chronic knee pain from osteoarthritis or following arthroplasty is a common problem. A number of publications have reported analgesic success of radiofrequency (RF) procedures on nerves innervating the knee, but interpretation is hampered by lack of clarity regarding indications, clinical protocols, targets, and longevity of benefit from RF procedures. We reviewed the following medical literature databases for publications on RF procedures on the knee joint for chronic pain: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar up to August 9, 2015. Data on scores for pain, validated scores for measuring physical disability, and adverse effects measured at any timepoint after 1 month following the interventions were collected, analyzed, and reported in this narrative review. Thirteen publications on ablative or pulsed RF treatments of innervation of the knee joint were identified. A high success rate of these procedures in relieving chronic pain of the knee joint was reported at 1 to 12 months after the procedures, but only 2 of the publications were randomized controlled trials. There was evidence for improvement in function and a lack of serious adverse events of RF treatments. Radiofrequency treatments on the knee joint (major or periarticular nerve supply or intra-articular branches) have the potential to reduce pain from osteoarthritis or persistent postarthroplasty pain. Ongoing concerns regarding the quality, procedural aspects, and monitoring of outcomes in publications on this topic remain. Randomized controlled trials of high methodological quality are required to further elaborate role of these interventions in this population.

Full Text Available Background: This prospective double-blind trial was undertaken to analyze the role of perioperatively administered dexmedetomidine on the occurrence of chronic pain in cases undergoing surgery for breast cancer. Subjects and Methods: Eighty-six cases were randomly assigned to two groups to receive either dexmedetomidine (2 μg/ml in group D or saline in group C, in a loading dose of 0.5 ml/kg, intravenous (IV, 30 min prior to induction, followed by a continuous infusion of 0.25 ml/kg/h IV till the completion of surgery, and then the dose tapered to 0.1 ml/kg/h for up to 24 h. The standardized questionnaires that measured chronic pain (Brief Pain Inventory, BPI; Short Form McGill Pain Questionnaire, SF-MPQ2 and quality of life (Quality of Life Scale, QOLS were gathered after 3 months of surgery as a primary outcome. Pain (verbal numerical score, VNS, sedation scores (Ramsay scoring, and analgesic requirements were also assessed for 72 h postoperatively. Results: In total, 84 cases (n=42 were analyzed for acute pain and 69 (34 in group D and 35 in group C for chronic pain. The consumption of isoflurane/fentanyl intra-operatively and paracetamol postoperatively was significantly lower in Group D. The sedation scores were non-significant between the groups. The VNS at rest and after movement was significantly lower in group D at corresponding times (except at 60 min throughout the assessment period. The BPI and SF-MPQ2 scores were significantly lower in group D in most of the factors. The QOLS score was significantly better in group D in all items except for relationships, friends, and learning. Conclusion: The perioperative infusion of dexmedetomidine has a pivotal role in attenuating the incidence and severity of chronic pain and improving the quality of life in cases undergoing breast cancer surgery.
disability. 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 goal setting into a clear and goal-oriented context that provides the patient with control and improved quality of life.

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.

available evidence suggests physical activity and exercise is an intervention with few adverse events that may improve pain severity and physical function, and consequent quality of life. However, further research is required and should focus on increasing participant numbers, including participants with a broader spectrum of pain severity, and lengthening both the intervention itself, and the follow-up period. Physical activity and exercise for chronic pain in adults - an overview of Cochrane Reviews Background Chronic (long-term) pain is pain that has lasted beyond the body's usual healing time. It is often described as pain that has lasted for at least three months. Chronic pain causes many problems, beyond the pain itself, including fatigue, anxiety, depression, and a poor quality of life. In the past, people with chronic pain were told to rest. However, general advice now is to keep active - whether to affect the pain directly or to combat the other problems associated with it. Therefore, research studies have attempted to examine the effect of physical activity in people with chronic pain. This overview aimed to bring together and analyse any reviews published by Cochrane that looked at physical activity and exercise studies in any chronic pain condition, including arthritis, back and neck pain, and menstrual (period) pain. Key results and quality of the evidence In January 2016, we identified 21 Cochrane Reviews which covered 10 different diagnoses (osteoarthritis (a joint disease), rheumatoid arthritis (joint pain and swelling), fibromyalgia (widespread pain condition), low back pain, intermittent claudication (cramping pain in the legs), dysmenorrhoea (period pain), mechanical neck disorders (neck pain), spinal cord injury, postpolio syndrome (a condition occurring in people who have had polio), patellofemoral pain (pain at the front of the knee)). The physical activity or exercise programme used in the trials ranged in frequency, intensity, and type, including

Sleep disturbance in chronic pain is common, occurring in two-thirds of patients. There is a complex relationship between chronic pain and sleep; pain can disrupt sleep and poor sleep can exaggerate pain intensity. This may have an impact on both depressive symptoms and attention to pain. This study aims to evaluate the relationship between chronic pain and sleep, and the role of mood and attention. Chronic pain patients, recruited from a secondary care outpatient clinic, completed self-report measures of pain, sleep, depressive symptoms and attention to pain. Hierarchical regression and structural equation modelling were used to explore the relationships between these measures. Participants (n = 221) were aged between 20 and 84 (mean = 52) years. The majority of participants were found to be 'poor sleepers' (86%) with increased pain severity, depressive symptoms and attention to pain. Both analytical approaches indicated that sleep disturbance is indirectly associated with increased pain severity Instead the relationship shared by sleep disturbance and pain severity was further associated with depressive symptoms and attention to pain. Our results indicate that sleep disturbance may contribute to clinical pain severity indirectly though changes in mood and attention. Prospective studies exploring lagged associations between these constructs could have critical information relevant to the treatment of chronic pain.

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

By the time a patient with severe refractory pain sees a pain specialist for evaluation and management, that patient has likely tried and failed several nonpharmacologic and pharmacologic approaches to pain treatment. Although relegated to one of the interventions of “last resort”, intrathecal drug delivery can be useful for improving pain control, optimizing patient functionality, and minimizing the use of systemic pain medications in appropriately selected patients. Due to its clinical and logistical requirements, however, intrathecal drug delivery may fit poorly into the classic pain clinic/interventional model and may be perceived as a "critical mass" intervention that is feasible only for large practices that have specialized staff and appropriate office resources. Potentially, intrathecal drug delivery may be more readily adopted into larger practices that can commit the necessary staff and resources to support patients' needs through the trialing, initiation, monitoring, maintenance, and troubleshooting phases of this therapy. Currently, two agents – morphine and ziconotide – are approved by the United States Food and Drug Administration for long-term intrathecal delivery. The efficacy and safety profiles of morphine have been assessed in long-term, open-label, and retrospective studies of >400 patients with chronic cancer and noncancer pain types. The efficacy and safety profiles of ziconotide have been

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.

Roland Morris scale. There was moderate to low quality evidence of an effect on work outcomes (OR at long term 1.87, 95% CI 1.39 to 2.53). There was insufficient evidence to assess whether MBR interventions were associated with more adverse events than usual care or physical interventions.Sensitivity analyses did not suggest that the pooled estimates were unduly influenced by the results from low quality studies. Subgroup analyses were inconclusive regarding the influence of baseline symptom severity and intervention intensity. Patients with chronic LBP receiving MBR are likely to experience less pain and disability than those receiving usual care or a physical treatment. MBR also has a positive influence on work status compared to physical treatment. Effects are of a modest magnitude and should be balanced against the time and resource requirements of MBR programs. More intensive interventions were not responsible for effects that were substantially different to those of less intensive interventions. While we were not able to determine if symptom intensity at presentation influenced the likelihood of success, it seems appropriate that only those people with indicators of significant psychosocial impact are referred to MBR.

The aims of the current study were to calibrate the item parameters of the Dutch-Flemish PROMIS Pain Behavior item bank using a sample of Dutch patients with chronic pain and to evaluate cross-cultural validity between the Dutch-Flemish and the US PROMIS Pain Behavior item banks. Furthermore, reliability and construct validity of the Dutch-Flemish PROMIS Pain Behavior item bank were evaluated. The 39 items in the bank were completed by 1042 Dutch patients with chronic pain. To evaluate unidimensionality, a one-factor confirmatory factor analysis (CFA) was performed. A graded response model (GRM) was used to calibrate the items. To evaluate cross-cultural validity, Differential item functioning (DIF) for language (Dutch vs. English) was evaluated. Reliability of the item bank was also examined and construct validity was studied using several legacy instruments, e.g. the Roland Morris Disability Questionnaire. CFA supported the unidimensionality of the Dutch-Flemish PROMIS Pain Behavior item bank (CFI = 0.960, TLI = 0.958), the data also fit the GRM, and demonstrated good coverage across the pain behavior construct (threshold parameters range: -3.42 to 3.54). Analysis showed good cross-cultural validity (only six DIF items), reliability (Cronbach's α = 0.95) and construct validity (all correlations ≥0.53). The Dutch-Flemish PROMIS Pain Behavior item bank was found to have good cross-cultural validity, reliability and construct validity. The development of the Dutch-Flemish PROMIS Pain Behavior item bank will serve as the basis for Dutch-Flemish PROMIS short forms and computer adaptive testing (CAT). © 2015 European Pain Federation - EFIC®

Pharmacological treatment of chronic (neuropathic) pain is often disappointing. In order to enhance our insight in the complex interaction between analgesic drug and chronic pain relief, we performed a pharmacokinetic-pharmacodynamic (PK-PD) modeling study on the effect of S(+)-ketamine on pain scores in Complex Regional Pain Syndrome type 1 (CRPS-1) patients. Sixty CRPS-1 patients were randomly allocated to received a 100-h infusion of S(+)-ketamine or placebo. The drug infusion rate was slowly increased from 5 mg/h (per 70 kg) to 20 mg/h based upon the effect/side effect profile. Pain scores and drug blood samples were obtained during the treatment phase and pain scores were further obtained weekly for another 11 weeks. A population PK-PD model was developed to analyze the S(+)-ketamine-pain data. Plasma concentrations of S(+)-ketamine and its metabolite decreased rapidly upon the termination of S(+)-ketamine infusion. The chance for an analgesic effect from ketamine and placebo treatment was 67±10% and 23±9% (population value±SE), respectively. The pain data were well described by the PK-PD model with parameters C(50)=10.5±4.8 ng/ml (95% ci 4.37-21.2 ng/ml) and t½ for onset/offset=10.9±4.0 days (5.3-20.5 days). Long-term S(+)-ketamine treatment is effective in causing pain relief in CRPS-1 patients with analgesia outlasting the treatment period by 50 days. These data suggest that ketamine initiated a cascade of events, including desensitization of excitatory receptor systems in the central nervous system, which persisted but slowly abated when ketamine molecules were no longer present.

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 maintaining activity is key to successful pain management, and important to health and wellbeing, it is known that older people in pain frequently alter or reduce activity levels. A 'fear-avoidance' model is often used to explain avoidance of activity in the face of pain. However, this model is not intended to take account of the wider context in which activity changes take place, nor older people's own explanations for their behaviour. to investigate the reasons why older people in the community adjust their activity levels when living with chronic pain. thirty-one people aged between 67 and 92 were purposively sampled from respondents to a community-based cross-sectional survey. All participants had reported long-term pain and were interviewed about this. Data were collected and analysed using a qualitative constructivist grounded theory approach. explanations for deliberative reduction or ceasing of activities reflected a desire to prevent pain exacerbation, thereby avoiding medical intervention. It also reflected a desire to safeguard autonomy in the face of pain in older age. Restrictions were often rationalised as normal in older age, although co-existing accounts of perseverance and frustration with limitation were also evident. a rational desire to avoid pain exacerbation and medical intervention motivated restrictions to activity. However, deliberative limitation of activity has the potential to compromise autonomy by increasing social isolation and de-conditioning. Supporting older people with pain to be active requires sensitivity to the function of activity restriction, especially as a means of preventing deterioration.

Social interactions can influence the experience and impact of chronic pain. Children and adolescents expectations of how others respond to them could therefore influence their adjustment to pain. This study examined how children and adolescents expected their peers and teachers would react to classmates with chronic pain. 211 school children participated in this study. We presented each participant 1 of 4 vignettes that described a boy or a girl who did or did not have chronic pain. Participants were then asked to describe how they think other children and their teachers would react to the child depicted in the vignette with respect to solicitous, discouraging, and coping responses. Discouraging responses from peers and teachers were viewed as being relatively unlikely. However, both coping and solicitous responses-the latter being a response known to be linked to increased pain and disability in children and adults-were viewed by the participating children as being relatively likely. Moreover, the expected likelihood of solicitous responses from teachers was thought to be even more probable for children and adolescents with chronic pain than for those without chronic pain. The results of this study have important practical implications, given the well-known importance of significant other's responses to chronic pain problems. Further research is needed to understand how social interactions at school may influence functioning of children with chronic pain and their development. This information could provide an important empirical basis for determining how best to manage individuals with chronic pain problems in the school setting.

The aim of this study was to investigate the effectiveness of balneotherapy (BT), which is applied in addition to physical therapy (PT), in the treatment of chronic neck pain. Sixty patients with chronic neck pain were divided into study (n = 30) and control (n = 30) groups. All of the patients in both groups were treated with a 15-session standard PT program consisting of hot pack, ultrasound, and transcutaneous electrical stimulation. Patients in the study group were also treated with a 15-session BT program lasting 20 min/day in addition to the standard PT program. Visual analogue scale (VAS), modified neck disability index (mNDI), and Nottingham Health Profile (NHP) scores of all patients were evaluated at three different times as pretreatment, posttreatment, and posttreatment third week. There was no statistically significant difference between the clinical and demographic characteristics of the patients in different groups before treatment. Intragroup analysis revealed significant improvement in all parameters for both of the groups at all time intervals. Intergroup analysis uncovered the superiority of the study group. According to the results of this study, BT in combination with PT is superior to PT alone in reducing pain and disability and improving quality of life in patients with chronic neck pain.

Low back pain (LBP) is chronic disease without a curative therapy. Alternative and complementary therapies are widely used in the management of this condition. To evaluate the efficacy of home application of Dead Sea mud compresses to the back of patients with chronic LBP. Forty-six consecutive patients suffering from chronic LBP were recruited. All patients were followed at the Soroka University Rheumatic Diseases Unit. The patients were randomized into two groups: one group was treated with mineral-rich mud compresses, and the other with mineral-depleted compresses. Mud compresses were applied five times a week for 3 consecutive weeks. The primary outcome was the patient's assessment of the overall back pain severity. The score of the Ronald & Morris questionnaire served as a secondary outcome. Forty-four patients completed the therapy and the follow-up assessments: 32 were treated with real mud packs and 12 used the mineral-depleted packs. A significant decrease in intensity of pain, as described by the patients, was observed only in the treatment group. In this group, clinical improvement was clearly seen at completion of therapy and was sustained a month later. Significant improvement in the scores of the Roland & Morris questionnaire was observed in both groups. The data suggest that pain severity was reduced in patients treated with mineral-rich mud compresses compared with those treated with mineral-depleted compresses. Whether this modest effect is the result of a "true" mud effect or other causes can not be determined in this study.
Chronic, noncancer pain such as that associated with osteoarthritis of the hip and knee is typically managed according to American College of Rheumatology guidelines. Patients unresponsive to first-line treatment with acetaminophen receive nonsteroidal antiinflammatory drugs (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors. However, many patients may have chronic pain that is refractory to these agents, or they may be at risk for the gastrointestinal, renal, and cardiovascular complications associated with their use. Tramadol, a mild opioid agonist and norepinephrine and serotonin reuptake inhibitor, is recommended by current guidelines for the treatment of moderate to moderately severe pain in patients who have not responded to previous oral therapy, or in patients who have contraindications to COX-2 inhibitors and nonselective NSAIDs. An extended-release (ER) formulation of tramadol was approved by the US Food and Drug Administration in September 2005. In contrast with immediate-release (IR) tramadol, this ER formulation allows once-daily dosing, providing around-the-clock analgesia. In clinical studies, tramadol ER has demonstrated a lower incidence of adverse events than that reported for IR tramadol. Unlike nonselective NSAIDs and COX-2 inhibitors, tramadol ER is not associated with gastrointestinal, renal, or cardiovascular complications. Although tramadol is an opioid agonist, significant abuse has not been demonstrated after long-term therapy. It is concluded that tramadol ER has an efficacy and safety profile that warrants its early use for the management of chronic pain, either alone or in conjunction with nonselective NSAIDs and COX-2 inhibitors.

To evaluate the perceptions of women with endometriosis and chronic pelvic pain regarding their social ties. A qualitative study was undertaken of women with chronic pelvic pain and endometriosis. Focus groups discussions among four to six participants were performed until saturation at the Clinics Hospital of Ribeirão Preto Medical School, Ribeirão Preto, southwest Brazil, between February 2013 and January 2014. Transcripts were analyzed according to the grounded theory approach and the emerging categories were coded using the WebQDA platform. Six focus group discussions took place, with a total of 29 patients. Social isolation was the main emerging theme. Social isolation was associated with a lack of understanding about endometriosis symptoms and with resignation in face of recurrent pain episodes. Avoiding partner intimacy and isolation from family and friends were components of social isolation. Women with endometriosis develop progressive social isolation after the onset of chronic pelvic pain. This finding is important for the multidisciplinary management of the disease.

An 8-item version of the Chronic Pain Acceptance Questionnaire (CPAQ-8) has recently been proposed and validated. The aims of this study were to further investigate the reliability and validity of the CPAQ-8 in a new sample. Questionnaires were completed by 550 people with chronic pain (478 online survey, 72 paper survey). A demographic and pain history questionnaire was administered along with the CPAQ-8 and measures of pain self-efficacy, pain catastrophizing, psychological flexibility in pain, anxiety, and mood. In addition, 105 respondents completed the CPAQ-8 within 6 weeks to provide test-retest reliability data. The 2-factor structure of the CPAQ-8 (Activity Engagement [AE] and Pain Willingness [PW]) was confirmed and had reasonable-to-good scale score reliability and test-retest reliability. Pain acceptance as measured by the CPAQ-8 was associated with less depression, anxiety, pain interference, fear of reinjury, pain catastrophizing, and psychological inflexibility in pain, and higher levels of satisfaction with life, pain self-efficacy, and general acceptance. Furthermore, pain acceptance fully mediated the relationship between reported pain severity and emotional distress (anxiety and depression) and partially mediated the relationship between pain severity and pain interference in a structural equation model. The test-retest reliability after 4 to 6 weeks ranged from .68 for PW to .86 for AE; the overall score correlation was .81. We conclude that the CPAQ-8 is a reliable and valid measure of pain acceptance and that the 2 subscales of the measure each make an individual contribution to the prediction of adjustment in people with chronic pain. The present study provides further evidence for the reliability and validity of the CPAQ-8. Support was found for the 2 related subscales, PW and AE, which appear to work in synergy to influence levels of pain interference and emotional distress in people living with chronic pain.

Effect of pain neurophysiology education on physiotherapy students' understanding of chronic pain, clinical recommendations and attitudes towards people with chronic pain: a randomised controlled trial.
Colleary, G; O'Sullivan, K; Griffin, D; Ryan, C G; Martin, D J
To investigate the effect of pain neurophysiology education (PNE) on student physiotherapists': (1) knowledge of chronic pain; (2) attitudes towards patients with chronic pain; and (3) clinical recommendations for patients with chronic pain. Multicentre single-blind randomised controlled trial. One UK and one Irish university. Seventy-two student physiotherapists. Participants received either PNE (intervention) or a control education. Both were delivered in a 70-minute group lecture. (1) The Revised Pain Neurophysiology Quiz to assess knowledge; (2) the Health Care Pain Attitudes and Impairment Relationship Scale (HC-PAIRS) to assess attitudes; and (3) a case vignette to assess the appropriateness of clinical recommendations. Post education, the PNE group had a greater increase in pain neurophysiology knowledge [mean difference 4.0 (95% confidence interval 3.2 to 4.7), Pstudents in the PNE group were more likely to make appropriate recommendations regarding work (94% vs 56%), exercise (92% vs 56%), activity (94% vs 67%) and bed rest (69% vs 33%) compared with those in the control group (Pphysiotherapy students, and could be used on a more widespread basis. There is a need to investigate whether these findings can be replicated in other healthcare professions, and how well these reported changes lead to changes in actual clinical behaviour and the clinical outcomes of patients.

Little is known about the affected cognitive problems in chronic low back pain patients. For this patient cohort research mostly focused on memory of pain, rather than cognitive difficulties related to pain. Chronic pain may be associated with specific (yet undefined) cognitive deficits that affect everyday behaviour. We set out to compare the cognitive function of patients with chronic low back pain (cLBP) in the course of multidisciplinary pain treatments before and after therapy. Thirty-three patients with cLBP and 25 healthy controls between 20 and 70 years were recruited into the study. The inclusion criteria for patients were: (1) a history of at least 12 weeks of chronic myofascial low back pain without radicular pain sensation before enrolment; (2) grade II and higher chronicity according to von Korff; (3) no opioid medication. The patients recruited had a mean pain duration of 7.13±7.16 years and reported a mean pain intensity of 6.62±2.04 (visual analogue score, VAS). Their mean back function according to the Funktionsfragebogen Hannover (FFbH, a questionnaire comparable with the Health Assessment Questionnaire) was 52.39±20.23%. At three time points (before therapy, 3 weeks and 6 months after therapy) the study subjects were assessed prospectively with a battery of visual memory tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). These included choice reaction time (CRT), pattern recognition memory (PRM) and spatial span (SSP). In parallel, the Trail-Making Test (TMT-A, TMT-B) and the Wechsler Adult Intelligence Scale (WAIS-III) were used to evaluate intelligence and cognitive flexibility. At the beginning of MDPT (T1), it took patients with cLBP significantly longer than HC to complete TMT-A (38.29±19.99s vs 30.25±14.19s, p=0.047) and TMT-B (72.10±26.98s vs 55.99±22.14s, p=0.034). There were no significant differences between patients and HC in CRT, PRM and SSP. Three weeks (T2) and 6 months (T3) after MDPT, TMT

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. Copyright © 2014 Elsevier Inc. All rights reserved.

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.

Evidence that patients with chronic pain selectively attend to pain-related stimuli presented in modified Stroop and dot-probe paradigms is mixed. The pain-related stimuli used in these studies have been primarily verbal in nature (i.e., words depicting themes of pain). The purpose of the present study was to determine whether patients with chronic pain, relative to healthy controls, show selective attention for pictures depicting painful faces. To do so, 170 patients with chronic pain and 40 age- and education-matched healthy control participants were tested using a dot-probe task in which painful, happy, and neutral facial expressions were presented. Selective attention was denoted using the mean reaction time and the bias index. Results indicated that, while both groups shifted attention away from happy faces (and towards neutral faces), only the control group shifted attention away from painful faces. Additional analyses were conducted on chronic pain participants after dividing them into groups on the basis of fear of pain/(re)injury. The results of these analyses revealed that while chronic pain patients with high and low levels of fear both shifted attention away from happy faces, those with low fear shifted attention away from painful faces, whereas those with high fear shifted attention towards painful faces. These results suggest that patients with chronic pain selectively attend to facial expressions of pain and, importantly, that the tendency to shift attention towards such stimuli is positively influenced by high fear of pain/(re)injury. Implications of the findings and future research directions are discussed.

Context: Lower back pain is considered to be one of the most common complaints that brings a patient to a pain specialist. Several modalities in interventional pain management are known to be helpful to a patient with chronic low back pain. Proper diagnosis is required for appropriate intervention to provide optimal benefits. From simple trigger point injections for muscular pain to a highly complex intervention such as a spinal cord stimulator are very effective if chosen properly. The aim of this article is to provide the reader with a comprehensive reading for treatment of lower back pain using interventional modalities. Evidence Acquisition: Extensive search for published literature was carried out online using PubMed, Cochrane database and Embase for the material used in this manuscript. This article describes the most common modalities available to an interventional pain physician along with the most relevant current and past references for the treatment of lower back pain. All the graphics and images were prepared by and belong to the author. Results: This review article describes the most common modalities available to an interventional pain physician along with the most relevant current and past references for the treatment of lower back pain. All the graphics and images belong to the author. Although it is beyond the scope of this review article to include a very detailed description of each procedure along with complete references, a sincere attempt has been made to comprehensively cover this very complex and perplexing topic. Conclusion: Lower back pain is a major healthcare issue and this review article will help educate the pain practitioners about the current evidence based treatment options. PMID:26484298

Returning to work after periods of sick-leave due to chronic pain problems, involve a number of situations of interpersonal nature (e.g. meeting supervisors/insurance companies to adapt work setting to present functional level, receive help from colleagues, express pain, etc.). Since chronic pain has shown co-morbidity with social anxiety, it is of interest to investigate restraining factors in return to work among chronic pain sufferers from a social perspective. Catastrophizing is identified in both pain and social anxiety as a mechanism that might fuel a continuous bias in how situations are perceived (threat) and by hindering the development of functional behavior strategies. The presence of social anxiety in chronic pain patients might be seen as a stressor that limits the individuals' ability to effectively communicate pain-related needs to colleagues, and/or employers and therefore act as a hindering factor in return-to-work. Hence, the overall aim of this study was to examine the relationship between social anxiety, pain catastrophizing, and perceived ability to communicate pain-related needs to the work environment in a clinical pain population. The study employed a cross-sectional design and involved 247 individuals with chronic pain (82.3% women; M age =44 years). Measures included the Pain catastrophizing Scale, the Social Phobia Screening Questionnaire and the communication of pain-related needs-subscale of the Return-To-Work Self-efficacy Questionnaire. Analyzes were run to examine whether social anxiety moderated the relation between pain catastrophizing, and perceived ability to communicate pain-related needs while controlling for pain severity/interference and sick leave. Social anxiety and pain catastrophizing correlated positively with each other and negatively with perceived ability to communicate pain-related needs. No support was obtained for a moderating effect of social anxiety. However, social anxiety and pain interference were each

Assistant professor, Department of surgery, Faculty of medicine, Babol University of medical sciences Abstract Background: Acute appendicitis is a completely known disease but for many physicians chronic appendicitis is unknown and some of them don believe in it. Although the number of people suffer from chronic appendicitis is much fewer than those who suffer from acute appendicitis, we shouldn ignore it. Clinical symptoms for these patients are chronic, longtime and recurrent abdominal pain, which is usually in the right lower quadrant of the abdomen. In the Para clinical examinations there isn any considerable pathological problem (in urine, stool, and sonography of the abdomen and pelvis. By recognizing appendicitis and appendectomy, the symptoms will be vanished and the patients will recover. Case presentation: The case was a 57-year-old man who has complained from chronic abdominal pain in the RLQ area since 15years ago. No pathological problem had been found in all diagnostic process. Conclusion: The problem was diagnosed as the chronic appendicitis and he underwent the appendectomy by laparoscopic procedure and was completely recovered.

To examine the temporal stability of conditioned pain modulation (CPM), formerly termed diffuse noxious inhibitory controls, among a sample of patients with chronic pain. The study also examined the factors that might be responsible for the stability of CPM. In this test-retest study, patients underwent a series of standardized psychophysical pain-testing procedures designed to assess CPM on two separate occasions (i.e., baseline and follow up). Patients also completed self-report measures of catastrophizing (Pain Catastrophizing Scale [PCS] and negative affect [NA]). Overall, results provided evidence for the stability of CPM among patients with chronic pain. Results, however, revealed considerable sex differences in the stability of CPM. For women, results revealed a significant test-retest correlation between baseline and follow-up CPM scores. For men, however, the test-retest correlation between baseline and follow-up CPM scores was not significant. Results of a Fisher's Z-test revealed that the stability of CPM was significantly greater for women than for men. Follow-up analyses revealed that the difference between men and women in the stability of CPM could not be accounted for by any demographic (e.g., age) and/or psychological factors (PCS and NA). Our findings suggest that CPM paradigms possess sufficient reliability to be incorporated into bedside clinical evaluation of patients with chronic pain, but only among women. The lack of CPM reproducibility/stability observed among men places limits on the potential use of CPM paradigms in clinical settings for the assessment of men's endogenous pain-inhibitory function.

Dexketoprofen, an NSAID used in the management of acute and chronic pains, is licensed in several countries but has not previously been the subjected of a systematic review. We used published and unpublished information from randomised clinical trials (RCTs) of dexketoprofen in painful conditions to assess evidence on efficacy and harm. PubMed and Cochrane Central were searched for RCTs of dexketoprofen for pain of any aetiology. Reference lists of retrieved articles and reviews were also searched. Menarini Group produced copies of published and unpublished studies (clinical trial reports). Data were abstracted into a standard form. For studies reporting results of single dose administration, the number of patients with at least 50% pain relief was derived and used to calculate the relative benefit (RB) and number-needed-to-treat (NNT) for one patient to achieve at least 50% pain relief compared with placebo. Thirty-five trials were found in acute pain and chronic pain; 6,380 patients were included, 3,381 receiving dexketoprofen. Information from 16 trials (almost half the total patients) was obtained from clinical trial reports from previously unpublished trials or abstracts. Almost all of the trials were of short duration in acute conditions or recent onset pain.All 12 randomised trials that compared dexketoprofen (any dose) with placebo found dexketoprofen to be statistically superior. Five trials in postoperative pain yielded NNTs for 12.5 mg dexketoprofen of 3.5 (2.7 to 4.9), 25 mg dexketoprofen of 3.0 (2.4 to 3.9), and 50 mg dexketoprofen of 2.1 (1.5 to 3.5). In 29/30 active comparator trials, dexketoprofen at the dose used was at least equivalent in efficacy to comparator drugs. Adverse event withdrawal rates were low in postoperative pain and somewhat higher in trials of longer duration; no serious adverse events were reported. Dexketoprofen was at least as effective as other NSAIDs and paracetamol/opioid combinations. While adverse event withdrawal was not

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.

Although little is known about its origins, neck pain may be related to several associated anatomical pathologies. We aimed to characterize the incidence and features of chronic neck pain and analyze the relationship between neck pain severity and its affecting factors. Between March 2012 and July 2013, we studied 216 patients with chronic neck pain. Initially, combined tramadol (37.5 mg) plus acetaminophen (325 mg) was administered orally twice daily (b.i.d.) to all patients over a 2-week period. After two weeks, patients were evaluated for neck pain during an outpatient clinic visit. If the numeric rating scale of the patient had not decreased to 5 or lower, a cervical medial branch block (MBB) was recommended after double-dosed previous medication trial. We classified all patients into two groups (mild vs. severe neck pain group), based on medication efficacy. Logistic regression tests were used to evaluate the factors associated with neck pain severity. A total of 198 patients were included in the analyses, due to follow-up loss in 18 patients. While medication was successful in reducing pain in 68.2% patients with chronic neck pain, the remaining patients required cervical MBB. Lateral cervical curvature, such as a straight or sigmoid type curve, was found to be significantly associated with the severity of neck pain. We managed chronic neck pain with a simple pharmacological management protocol followed by MBB. We should keep in mind that it may be difficult to manage the patient with straight or sigmoid lateral curvature only with oral medication.

Of the three broad outcome domains of body functions and structures, activities, and participation (eg, engaging in valued social roles) outlined in the World Health Organization's (WHO) International Classification of Functioning, Disability and Health (ICF), it has been argued that participation is the most important to individuals, particularly those with chronic health problems. Yet, participation is not commonly measured in back pain research. The aim of this study was to investigate the construct validity of a modified 5-Item Pain Disability Index (PDI) score as a measure of participation in people with chronic back pain. A validation study was conducted using cross-sectional data. Participants with chronic back pain were recruited from a multidisciplinary pain center in Alberta, Canada. The outcome measure of interest is the 5-Item PDI. Each study participant was given a questionnaire package containing measures of participation, resilience, anxiety and depression, pain intensity, and pain-related disability, in addition to the PDI. The first five items of the PDI deal with social roles involving family responsibilities, recreation, social activities with friends, work, and sexual behavior, and comprised the 5-Item PDI seeking to measure participation. The last two items of the PDI deal with self-care and life support functions and were excluded. Construct validity of the 5-Item PDI as a measure of participation was examined using Pearson correlations or point-biserial correlations to test each hypothesized association. Participants were 70 people with chronic back pain and a mean age of 48.1 years. Forty-four (62.9%) were women. As hypothesized, the 5-Item PDI was associated with all measures of participation, including the Participation Assessment with Recombined Tools-Objective (r=-0.61), Late-Life Function and Disability Instrument: Disability Component (frequency: r=-0.66; limitation: r=-0.65), Work and Social Adjustment Scale (r=0.85), a global

OBJECTIVE: Chronic tension-type headache (CTTH) affects 3% of the population. Directly and indirectly it causes high costs and considerable loss of quality of life. The mechanisms of this disorder are poorly understood and the treatment possibilities are therefore limited. The blink reflex (BR......) reflects neuronal excitability due to nociceptive input in the brainstem. The aim of this study was to investigate nociceptive processing at the level of the brainstem in an experimental pain model of CTTH symptoms. METHODS: The effect of conditioning pain, 5 min infusion of hypertonic saline into the neck...... muscles, was investigated in 20 patients with CTTH and 20 healthy controls. In addition, a pilot study with isotonic saline was performed with 5 subjects in each group. The BR was elicited by electrical stimuli with an intensity of four times the pain threshold, with a superficial concentric electrode. We...

[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 ...

Chronic pelvic pain syndrome (CPPS) presents with a variety of symptoms affecting multiple systems. There is no universal treatment that can be given to all patients with CPPS. The results of treatment depend greatly on an accurate diagnosis. A thorough clinical assessment, including a "four-step plan", should include paying special attention to the musculoskeletal system. This assessment is not difficult to perform and provides valuable information on possible muscular problems and neuropathy.

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. 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. 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). 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 prostatitis/chronic pelvic pain syndrome remains unknown

The aim of this study is to determine the effectiveness of balneotherapy plus physical therapy versus only physical therapy in patients with chronic low back pain. In this trial, 81 patients with low back pain were followed up in two groups. Patients in group I (n = 44) were treated with physical therapy alone. Patients in group II (n = 37) were treated with balneotherapy in addition to the same physical therapy protocol in group I. Patients in both groups were given a home-based standardized exercise program. The following parameters were measured: visual analog scale (0-10 cm), fingertip-to-floor distance (cm), Oswestry Disability Index, and Short Form 36 quality of life scale. First evaluations were done at the time of enrollment, and second evaluations were done after accomplishment of a 3-week treatment program. There were no significant differences between the two groups for the sociodemographic features. All of the measured parameters improved in both groups. However, improvements in pain, functionality, and quality of life scores were found to be superior in the balneotherapy plus physical therapy group. For the patients with chronic low back pain, balneotherapy plus physical therapy is more effective, compared to physical therapy alone.

Chronic orofacial pain is a symptom associated with a wide range of neuropathic, neurovascular, idiopathic, and myofascial conditions that affect a significant proportion of the population. While the collective impact of the subset of the orofacial pain disorders involving neurogenic and idiopathic mechanisms is substantial, some of these are relatively uncommon. Hence, patients with these disorders can be vulnerable to misdiagnosis, sometimes for years, increasing the symptom burden and delaying effective treatment. This manuscript first reviews the decision tree to be followed in diagnosing any neuropathic pain condition, as well as the levels of evidence needed to make a diagnosis with each of several levels of confidence: definite, probable, or possible. It then examines the clinical literature related to the idiopathic and neurogenic conditions that can occasion chronic orofacial pain, including burning mouth syndrome, trigeminal neuralgia, glossopharyngeal neuralgia, post-herpetic neuralgia, and atypical odontalgia. Temporomandibular disorders also are examined as are other headache conditions, even though they are not neurologic conditions, because they are common and can mimic symptoms of the latter disorders. For each of these conditions, the paper reviews literature regarding incidence and prevalence, physiologic and other contributing factors, diagnostic signs and symptoms, and empirical evidence regarding treatments. Finally, in order to improve the quality and accuracy of clinical diagnosis, as well as the efficiency with which effective treatment is initiated and delivered, criteria are offered that can be instrumental in making a differential diagnosis.

Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure. To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions. We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of

Cannabis is increasingly being used in the treatment of chronic pain. However, there is a lack of available research in the population of patients with chronic pain who are using cannabis. The current study examines clinical and treatment characteristics for patients who are admitted to a 3-week outpatient interdisciplinary chronic pain rehabilitation program. Participants (N=48) included patients with a positive urine drug screen for 9-carboxy-tetrahydrocannabinol (THC(+); n=24) and a matched comparison sample of patients with a negative screen (THC(-); n=24). Participants were matched for age, gender, race, education, and current prescription opioid use. Measures of pain, functioning, and quality of life were completed at admission and discharge. Medical chart review was conducted to assess medication and substance use history. Participants with a positive screen for THC were more likely to report a past history of illicit substance use, alcohol abuse, and current tobacco use. Cannabis use was not associated with a significantly lower morphine equivalence level for participants using prescription opioids (n=14). Both groups of participants reported significant improvement in pain severity, pain interference, depressive symptoms, and pain catastrophizing. There were no group- or treatment-related differences in these outcome variables. Results provide preliminary evidence that patients with chronic pain using cannabis may benefit from an interdisciplinary chronic pain program. Patients with chronic pain using cannabis may be at higher risk for substance-related negative outcomes, although more research is needed to understand this relationship.

Full Text Available Abstract Background On-going pain is one of the most debilitating symptoms associated with a variety of chronic pain disorders. An understanding of mechanisms underlying on-going pain, i.e. stimulus-independent pain has been hampered so far by a lack of behavioural parameters which enable studying it in experimental animals. Ultrasound vocalizations (USVs have been proposed to correlate with pain evoked by an acute activation of nociceptors. However, literature on the utility of USVs as an indicator of chronic pain is very controversial. A majority of these inconsistencies arise from parameters confounding behavioural experiments, which include novelty, fear and stress due to restrain, amongst others. Results We have developed an improved assay which overcomes these confounding factors and enables studying USVs in freely moving mice repetitively over several weeks. Using this improved assay, we report here that USVs increase significantly in mice with bone metastases-induced cancer pain or neuropathic pain for several weeks, in comparison to sham-treated mice. Importantly, analgesic drugs which are known to alleviate tumour pain or neuropathic pain in human patients significantly reduce USVs as well as mechanical allodynia in corresponding mouse models. Conclusions We show that studying USVs and mechanical allodynia in the same cohort of mice enables comparing the temporal progression of on-going pain (i.e. stimulus-independent pain and stimulus-evoked pain in these clinically highly-relevant forms of chronic pain.

DATA SOURCES Electronic databases PubMed, Healthline, OmniMedicalSearch, Medscape, and EMBASE were searched from 1990 to January 2016. STUDY SELECTION Prospectively designed studies that used dextrose as the sole active prolotherapy constituent were selected. DATA EXTRACTION Two independent reviewers rated studies for quality of evidence using the Physiotherapy Evidence Database assessment scale for randomized controlled trials (RCTs) and the Downs and Black evaluation tool for non-RCTs, for level of evidence using a modified Sackett scale, and for clinically relevant pain score difference using minimal clinically important change criteria. Study population, methods, and results data were extracted and tabulated. DATA SYNTHESIS Fourteen RCTs, 1 case–control study, and 18 case series studies met the inclusion criteria and were evaluated. Pain conditions were clustered into tendinopathies, osteoarthritis (OA), spinal/pelvic, and myofascial pain. The RCTs were high-quality Level 1 evidence (Physiotherapy Evidence Database ≥8) and found dextrose injection superior to controls in Osgood–Schlatter disease, lateral epicondylitis of the elbow, traumatic rotator cuff injury, knee OA, finger OA, and myofascial pain; in biomechanical but not subjective measures in temporal mandibular joint; and comparable in a short-term RCT but superior in a long-term RCT in low back pain. Many observational studies were of high quality and reported consistent positive evidence in multiple studies of tendinopathies, knee OA, sacroiliac pain, and iliac crest pain that received RCT confirmation in separate studies. Eighteen studies combined patient self-rating (subjective) with psychometric, imaging, and/or biomechanical (objective) outcome measurement and found both positive subjective and objective outcomes in 16 studies and positive

Trying to cope with chronic pain is a highly demanding and challenging task and pain patients often need to reformulate goals or aspirations due to their pain condition. This goal violation is often related with experienced distress and requires coping processes in order to decrease the distress and stimulate a healthy adaptation. Some scholars, however, argued that in so-called unsolvable or irreparable stressors such as chronic pain, conventional coping strategies like problem-focused coping might not be the most adaptive option. In these situations, meaningful coping strategies attempting to transform the meaning of the stressful experience would be more accurate. In this study, we aim to test if goal violation triggers meaningful coping strategies over time and whether engagement in these meaningful coping strategies result in improved life satisfaction, as an indicator of adaptation. A longitudinal three wave study in a sample of paint patients (n = 125) tests whether goal violation triggers positive reappraisal and downward comparison, two possible meaningful coping strategies. The study furthermore tests if engagement in these strategies results in a better adaptation to the pain condition, reflected in higher life satisfaction. Results partially supported our hypotheses by pointing to the benevolent role of downward comparison on life satisfaction via decreased goal violation of pain patients. Our findings however did also show that positive reappraisal predicted lower life satisfaction via increased levels of appraised goal violation which questions the role of positive reappraisal as a genuine meaningful coping strategy. Implications and limitations are discussed. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Current approaches to classification of chronic pain conditions suffer from the absence of a systematically implemented and evidence-based taxonomy. Moreover, existing diagnostic approaches typically fail to incorporate available knowledge regarding the biopsychosocial mechanisms contributing to pain conditions. To address these gaps, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration and the American Pain Society (APS) have joined together to develop an evidence-based chronic pain classification system called the ACTTION-APS Pain Taxonomy. This paper describes the outcome of an ACTTION-APS consensus meeting, at which experts agreed on a structure for this new taxonomy of chronic pain conditions. Several major issues around which discussion revolved are presented and summarized, and the structure of the taxonomy is presented. ACTTION-APS Pain Taxonomy will include the following dimensions: 1) core diagnostic criteria; 2) common features; 3) common medical comorbidities; 4) neurobiological, psychosocial, and functional consequences; and 5) putative neurobiological and psychosocial mechanisms, risk factors, and protective factors. In coming months, expert working groups will apply this taxonomy to clusters of chronic pain conditions, thereby devel
