Are Spirituality and Religiosity Resources for Patients with Chronic Pain Conditions?

PAIN MEDICINE, Issue 2 2009
Arndt Büssing Prof Dr
ABSTRACT Objective., We studied whether or not spirituality/religiosity is a relevant resource for patients with chronic pain conditions, and to analyze interrelations between spirituality/religiosity (SpREUK Questionnaire; SpREUK is an acronym of the German translation of "Spiritual and Religious Attitudes in Dealing with Illness"), adaptive coping styles that refer to the concept of locus of disease control (AKU Questionnaire; AKU is an acronym of the German translation of "Adaptive Coping with Disease"), life satisfaction, and appraisal dimensions. Patients., In a multicenter cross-sectional study, 580 patients with chronic pain conditions were enrolled. Results., We found that the patients relied on both external powerful sources of disease control and on internal powers and virtues, while Trust in Higher Source (intrinsic religiosity) or Illness as Chance (reappraisal) were valued moderately; Search for Meaningful Support/Access (spiritual quest orientation) was of minor relevance. Stepwise regression analyses revealed that the internal sources of disease control, such as Conscious and Healthy Way of Living and Positive Attitudes, were (apart from the religious denomination) the strongest predictors of patients' reliance on spirituality/religiosity. Both behavioral styles were rated significantly lower in patients who regarded themselves as neither religious nor spiritual. Positive disease interpretations such as Challenge and Value were clearly associated with a spiritual quest orientation and intrinsic religiosity. Conclusion., The associations between spirituality/religiosity, positive appraisals. and internal adaptive coping strategies indicate that the utilization of spirituality/religiosity goes far beyond fatalistic acceptance, but can be regarded as an active coping process. The findings support the need for further research concerning the contributions of spiritual coping in adjustment to chronic pain. [source]


Nonimmersive Virtual Reality Mirror Visual Feedback Therapy and Its Application for the Treatment of Complex Regional Pain Syndrome: An Open-Label Pilot Study

PAIN MEDICINE, Issue 4 2010
Kenji Sato MD
Abstract Objective., Chronic pain conditions such as phantom limb pain and complex regional pain syndrome are difficult to treat, and traditional pharmacological treatment and invasive neural block are not always effective. Plasticity in the central nervous system occurs in these conditions and may be associated with pain. Mirror visual feedback therapy aims to restore normal cortical organization and is applied in the treatment of chronic pain conditions. However, not all patients benefit from this treatment. Virtual reality technology is increasingly attracting attention for medical application, including as an analgesic modality. An advanced mirror visual feedback system with virtual reality technology may have increased analgesic efficacy and benefit a wider patient population. In this preliminary work, we developed a virtual reality mirror visual feedback system and applied it to the treatment of complex regional pain syndrome. Design., A small open-label case series. Five patients with complex regional pain syndrome received virtual reality mirror visual feedback therapy once a week for five to eight sessions on an outpatient basis. Patients were monitored for continued medication use and pain intensity. Results., Four of the five patients showed >50% reduction in pain intensity. Two of these patients ended their visits to our pain clinic after five sessions. Conclusion., Our results indicate that virtual reality mirror visual feedback therapy is a promising alternative treatment for complex regional pain syndrome. Further studies are necessary before concluding that analgesia provided from virtual reality mirror visual feedback therapy is the result of reversing maladaptive changes in pain perception.

Mazes, Conflict, and Paradox: Tools for Understanding Chronic Pain

PAIN PRACTICE, Issue 3 2009
Cary A. Brown PhD
Abstract This article presents an argument for framing chronic pain within a complex adaptive systems (CAS) paradigm. The first aim of this article is to demonstrate how chronic pain can be framed as a CAS and how paradox, one of the core characteristics of a CAS, exists within the chronic pain experience. The second aim is to illustrate how paradox exists at multiple levels within the health care encounter and ongoing experience of chronic pain. Finally, the article will use the example of interactions at the patient/clinician level to illustrate how health care workers' efforts to deal with issues emergent from the range of paradoxes have for the most part been ineffective, and at times harmful, to persons experiencing chronic pain. This article uses the example of chronic pain to explore how the manner in which health care providers and patients recognize and deal with paradoxes can either worsen the pain experience or help generate creative new ways to manage the chronic pain condition. The CAS principles discussed in this article hold application across a range of chronic conditions for which a traditional biomedical paradigm proves insufficient. [source]


Persistent Genital and Pelvic Pain after Childbirth

THE JOURNAL OF SEXUAL MEDICINE, Issue 1 2009
Laurel Q.P. Paterson BA
ABSTRACT Introduction., Although genital pain and pelvic pain are common and well-documented problems in the early postpartum period, little is known about their course. The few published studies of such pain beyond 1 year postpartum have focused primarily on the perineum and have not assessed pain onset. Aim., To investigate the prevalence and characteristics of all types of genital and pelvic pain in the second year postpartum, and to explore risk factors for their persistence. Methods., Over a 6-month period, a questionnaire on genital/pelvic pain, sociodemographic and childbirth variables, breastfeeding, and chronic pain history was mailed to patients of the collaborating obstetrician at 12 months postpartum. Main Outcome Measures., The prevalence, characteristics, and correlates of persistent genital/pelvic pain with postpartum onset. Results., Almost half of the 114 participants (82% response rate; M = 14 months postpartum) reported a current (18%) or resolved (26%) episode of genital or pelvic pain lasting 3 or more months. Just under one in 10 (9%) mothers continued to experience pain that had begun after they last gave birth. This pain was described at various locations (e.g., vaginal opening and pelvic area), as moderate in intensity and unpleasantness, and most often as burning, cutting, or radiating. Although it was triggered by both sexual and nonsexual activities, none of the mothers affected were receiving treatment. Univariate analyses revealed that only past diagnosis with a nongenital chronic pain condition (e.g., migraine headache) was significantly correlated with (i) any history of chronic genital/pelvic pain or (ii) the persistence of pregnancy- or postpartum-onset genital or pelvic pain. Conclusions., Postpartum genital and pelvic pain persists for longer than a year for a significant percentage of mothers. Women with a history of other chronic pain appear to be particularly vulnerable to developing persistent genital or pelvic pain. Paterson LQP, Davis SNP, Khalifé S, Amsel R, and Binik YM.

Allodynia in Migraine: Association With Comorbid Pain Conditions

HEADACHE, Issue 9 2009
Gretchen E. Tietjen MD
Background., Cutaneous allodynia (CA) in migraine is a clinical manifestation of central nervous system sensitization. Several chronic pain syndromes and mood disorders are comorbid with migraine. In this study we examine the relationship of migraine-associated CA with these comorbid conditions. We also evaluate the association of CA with factors such as demographic profiles, migraine characteristics, and smoking status that may have an influence on the relationships of CA to pain and mood. Methods., Data are from a cross-sectional multicenter study of comorbid conditions in persons seeking treatment in headache clinics. Diagnosis of migraine was determined by a physician based on the International Classification of Headache Disorders-II criteria. Participants completed a self-administered questionnaire ascertaining sociodemographics, migraine-associated allodynia, physician-diagnosed comorbid medical and psychiatric disorders, headache-related disability, current depression, and anxiety. Results., A total of 1413 migraineurs (mean age = 42 years, 89% women) from 11 different headache treatment centers completed a survey on the prevalence of comorbid conditions. Aura was reported by 38% and chronic headache by 35% of the participants. Sixty percent of the study population reported at least one migraine-related allodynic symptom, 10% reported ,4 symptoms. Symptoms of CA were associated with female gender, body mass index, current smoking, presence of aura, chronic headaches, transformed headaches, severe headache-related disability, and duration of migraine illness from onset. The prevalence of self-reported physician diagnosis of comorbid pain conditions (irritable bowel syndrome, chronic fatigue syndrome, fibromyalgia) and psychiatric conditions (current depression and anxiety) was also associated with symptoms of CA. Adjusted ordinal regression indicated a significant association between number of pain conditions and severity of CA (based on symptom count). Adjusting for sociodemographics, migraine characteristics, and current depression and anxiety, the likelihood of reporting symptoms of severe allodynia was much higher in those with 3 or more pain conditions (odds ratio = 3.03, 95% confidence interval: 1.78-5.17), and 2 pain conditions (odds ratio = 2.67, 95% confidence interval: 1.78-4.01) when compared with those with no comorbid pain condition. Conclusion., Symptoms of CA in migraine were associated with current anxiety, depression, and several chronic pain conditions. A graded relationship was observed between number of allodynic symptoms and the number of pain conditions, even after adjusting for confounding factors. This study also presents the novel association of CA symptoms with younger age of migraine onset, and with cigarette smoking, in addition to confirming several previously reported findings.

The Influence of Gender and Sex Steroids on Craniofacial Nociception

HEADACHE, Issue 2 2007
Brian E. Cairns PhD
Several pain conditions localized to the craniofacial region show a remarkable sex-related difference in their prevalence. These conditions include temporomandibular disorders and burning mouth syndrome as well as tension-type, migraine, and cluster headaches. The mechanisms that underlie sex-related differences in the prevalence of these craniofacial pain conditions remain obscure and likely involve both physiological and psychosocial factors. In terms of physiological factors relevant to the development of headache, direct evidence of sex-related differences in the properties of dural afferent fibers or durally activated second-order trigeminal sensory neurons has yet to be provided. There is, however, evidence for sex-related differences in the response properties of afferent fibers and second-order trigeminal sensory neurons that convey nociceptive input from other craniofacial tissues associated with sex-related differences in chronic pain conditions, such as those that innervate the masseter muscle and temporomandibular joint. Further, modulation of craniofacial nociceptive input by opioidergic receptor mechanisms appears to be dependent on biological sex. Research into mechanisms that may contribute to sex-related differences in trigeminal nociceptive processing has primarily focused on effect of the female sex hormone estrogen, which appears to alter the excitability of trigeminal afferent fibers and sensory neurons to noxious stimulation of craniofacial tissues. This article discusses current knowledge of potential physiological mechanisms that could contribute to sex-related differences in certain craniofacial pain conditions. [source]


Evaluation of a multidisciplinary outpatient pain management programme based at a community hospital

MUSCULOSKELETAL CARE, Issue 2 2009
Mei Wong DClinPsy
Objective:,To evaluate a multidisciplinary cognitive behavioural therapy pain management programme (PMP) based at a small community hospital. Methods:,Patients attending the PMP were assessed at three intervals (pre-training, and 18 and 44 weeks post-training) using a set of seven questionnaires. Information about their general practitioner (GP) and consultant visits was recorded at pre-training and final follow-up visits. Questionnaires were completed and additional personal information recorded before patients attended their appointments. Results:,Between 1997 and 2006, 163 patients completed at least six sessions out of the eight-week programme. Of these, 70 who had completed at least one questionnaire outcome measure at the three assessment intervals, and 83 who had provided information on their GP and consultant visits at pre-training and final follow-up, were included in the analyses. The results showed that patients reported being more confident in coping with their pain (pain self-efficacy questionnaire) at 18 weeks post-training and their improvement was sustained at the final follow-up. They were significantly less depressed (hospital and anxiety depression scale [HADS]) and reported a large improvement in their quality of life (modified patient generated index) at the final follow-up. They also reported a significant reduction in pain-related GP and consultant visits at their final follow-up. Although there were improvements in the Tampa scale of kinesiophobia, anxiety (HADS-Anx) and sickness impact profile scores, these were not statistically significant. Conclusion:,The result of the evaluation indicated that this PMP, delivered in a community hospital setting, made some significant differences to patients with intractable chronic pain conditions.

Role of spinal cord glia in the central processing of peripheral pain perception

NEUROGASTROENTEROLOGY & MOTILITY, Issue 5 2010
S. Bradesi
Abstract Background, The discovery that glial activation plays a critical role in the modulation of neuronal functions and affects the spinal processing of nociceptive signalling has brought new understanding on the mechanisms underlying central sensitization involved in chronic pain facilitation. Spinal glial activation is now considered an important component in the development and maintenance of allodynia and hyperalgesia in various models of chronic pain, including neuropathic pain and pain associated with peripheral inflammation. In addition, spinal glial activation is also involved in some forms of visceral hyperalgesia. Purpose, We discuss the signalling pathways engaged in central glial activation, including stress pathways, and the neuron,glia bidirectional relationships involved in the modulation of synaptic activity and pain facilitation. In this expanding field of research, the characterization of the mechanisms by which glia affect spinal neuro-transmission will increase our understanding of central pain facilitation, and has the potential for the development of new therapeutic agents for common chronic pain conditions.

The Role of Glia and the Immune System in the Development and Maintenance of Neuropathic Pain

PAIN PRACTICE, Issue 3 2010
Ricardo Vallejo MD
Abstract Neuropathic pain refers to a variety of chronic pain conditions with differing underlying pathophysiologic mechanisms and origins. Recent studies indicate a communication between the immune system and the nervous system. A common underlying mechanism of neuropathic pain is the presence of inflammation at the site of the damaged or affected nerve(s). This inflammatory response initiates a cascade of events resulting in the concentration and activation of innate immune cells at the site of tissue injury. The release of immunoactive substances such as cytokines, neurotrophic factors, and chemokines initiate local actions and can result in a more generalized immune response. The resultant neuroinflammatory environment can cause activation of glial cells located in the spinal cord and the brain, which appear to play a prominent role in nociception. Glial cells, also known as neuroglia, are nonconducting cells that modulate neurotransmission at the synaptic level. Glial cells can be subdivided into two primary categories: microglia and macroglia, which include astrocytes and oligodendrocytes. Astrocytes and microglia are known to play a role in the development, spread, and potentiation of neuropathic pain. Following peripheral nociceptive activation via nerve injury, microglia become activated and release pro-inflammatory cytokines such as tumor necrosis factor-,, interleukin-1,, and interleukin-6, thereby initiating the pain process. Microglia propagate the neuroinflammation by recruiting other microglia and eventually activating nearby astrocytes, which prolongs the inflammatory state and leads to a chronic neuropathic pain condition. Our review focuses on the role of glia and the immune system in the development and maintenance of neuropathic pain. [source]


Acupuncture for Chronic Pain: Is Acupuncture More than an Effective Placebo?

PAIN PRACTICE, Issue 2 2010
A Systematic Review of Pooled Data from Meta-analyses
Abstract Objectives: There is controversy as to whether or not acupuncture is more effective than placebo. To help clarify this debate, we synthesized the evidence gathered from systematic reviews on the pooled data of high-quality randomized controlled trials comparing acupuncture to sham acupuncture for chronic pain. Method: Systematic reviews of acupuncture for the most commonly occurring forms of chronic pain (back, knee, and head) published between 2003 and 2008 were sourced from Ovid databases: Medline, Allied and Complementary Medicine database, Cochrane Library and Web of Science during December 2008. Eight systematic reviews with meta-analyses of pooled data were eligible for inclusion. Data were extracted for short- and longer-term outcomes for the most commonly occurring forms of pain. Two independent reviewers assessed methodological quality. Results: For short-term outcomes, acupuncture showed significant superiority over sham for back pain, knee pain, and headache. For longer-term outcomes (6 to12 months), acupuncture was significantly more effective for knee pain and tension-type headache but inconsistent for back pain (one positive and one inconclusive). In general, effect sizes (standardized mean differences) were found to be relatively small. Discussion: The accumulating evidence from recent reviews suggests that acupuncture is more than a placebo for commonly occurring chronic pain conditions. If this conclusion is correct, then we ask the question: is it now time to shift research priorities away from asking placebo-related questions and shift toward asking more practical questions about whether the overall benefit is clinically meaningful and cost-effective?

Thalamic atrophy associated with painful osteoarthritis of the hip is reversible after arthroplasty: A longitudinal voxel-based morphometric study

ARTHRITIS & RHEUMATISM, Issue 10 2010
Stephen E. Gwilym
Objective Voxel-based morphometry (VBM) is a method of assessing brain gray matter volume that has previously been applied to various chronic pain conditions. From this previous work, it appears that chronic pain is associated with altered brain morphology. The present study was undertaken to assess these potential alterations in patients with painful hip osteoarthritis (OA). Methods We studied 16 patients with unilateral right-sided hip pain, before and 9 months after hip arthroplasty. This enabled comparison of gray matter volume in patients with chronic musculoskeletal pain versus healthy controls, as well as identification of any changes in volume following alleviation of pain (after surgery). Assessment involved self-completion questionnaires to assess pain, function, and psychosocial variables, and magnetic resonance imaging scanning of the brain for VBM analysis. Results Significant differences in brain gray matter volume between healthy controls and patients with painful hip arthritis were seen. Specifically, areas of the thalamus in patients with chronic OA pain exhibited decreased gray matter volume. Furthermore, when these preoperative changes were compared with the brain morphology of the patients 9 months after surgery, the areas of reduced thalamic gray matter volume were found to have "reversed" to levels seen in healthy controls. Conclusion Our findings confirm that gray matter volume decreases within the left thalamus in the presence of chronic pain and disability in patients with hip OA. The results also show that these thalamic volume changes reverse after hip arthroplasty and are associated with decreased pain and increased function. These findings have potential implications with regard to optimizing the timing of orthopedic interventions such as arthroplasty. [source]
