Impact of fibromyalgia on everyday life: a study of women in the USA and Sweden

A comparison of visual analog scale and shear-wave ultrasound elastography data in fibromyalgia patients and the normal population

[Purpose] The aim of this study was to compare Visual Analog Scale (VAS) values with the Shear Wave Elastography (SWE) values of rhomboid major muscles in fibromyalgia (FM) patients with those of a normal healthy population. [Participants and Methods] Evaluation was made of 53 female patients diagnosed with FM according to the American Collage of Rheumatology criteria, and a control group of 47 healthy volunteers with a VAS score of 0. All the patients were applied with ultrasonography. The severity of pain was measured using a VAS. [Results] Mean age was calculated as 39 years (range, 23–60 years) in the patient group and 37 years (range, 21–58 years) in the control group. The mean SWE value of the rhomboid major muscle of the patients was 4.74 m/sn and 70.21 kPa on the right side and 4.46 m/sn and 58.78 kPa on the left side. In the control group, these values were 4.18m/sn and 55.03 kPa on the right side and 3.78 m/sn and 44.21 kPa on the left side. The mean VAS score of the patients was 7.3. [Conclusion] The use of SWE values could be more objective than the subjective parameter of the VAS score in the evaluation of the severity of pain in fibromyalgia.

Self-reported disability in women with fibromyalgia from a tertiary care center

Background

The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument to assess disability. Pain and psychological factors seem to play a pronounced disabling role in fibromyalgia (FM). There are few studies that investigate the factors associated with disability in patients with fibromyalgia from the patient’s perspective. Information about FM disability using self-reported questionnaires is limited. This study aimed to assess the relationship between the ordinal response variable (degree of disability), and four explanatory variables: pain intensity, depression, anxiety, and alexithymia.

Methods

One hundred fifteen women with FM were enrolled in the cross-sectional study. For the assessment of disability the WHODAS 2.0 (36-item version) was used. Univariate and multivariate (ordinal logistic regression) analyses were performed to assess the relationship between pain (Visual Analogue Scale), depression and anxiety (Hospital Anxiety and Depression Scale), alexithymia (Modified Toronto Alexithymia Scale) and disability.

Results

Disability was detected by global WHODAS score in 114 patients (99%), with the corresponding percentages for mild, moderate and severe disability being 11.3, 46.96 and 40.87%, respectively. Global WHODAS score was more severe among subjects with depression (50 vs 36.4, p < 0.001, effect size = 0.33) and alexithymia (50 vs 33.6, p < 0.001, effect size = 0.38). Pain intensity mean scores for mild, moderate and severe disability were 5.0, 6.1 and 7.3, respectively (p < 0.001, omega-squared = 0.12). Pain intensity explained the global disability degree and its domains except for the cognitive one. Whereas, depression explained cognitive and personal relation domains. On the other hand, alexithymia explained global disability degree and all domains of WHODAS 2.0 questionnaire.

Conclusions

Most of the patients with fibromyalgia perceived themselves with moderate to severe disability. The main explanatory variables of the perceived disability were the pain intensity and psychological factors (alexithymia and depression).

Effects of Physical-Agent Pain Relief Modalities for Fibromyalgia Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Purpose

We conducted a systematic review and meta-analysis to investigate the effects of the following physical-agent modalities for pain relief in fibromyalgia (FM) patients.

Methods

We identified randomized controlled studies of adults with FM in the MEDLINE, CINAHL, and PEDro databases. The primary outcome measure was pain relief measured by a visual analogue scale (VAS), and the secondary outcome measures of interest were subjective improvements in the number of tender points, Fibromyalgia Impact Questionnaire (FIQ), and quality of life (QOL) scores.

Results

Eleven studies were included in our review. The studies' physical-agent modalities were low-level laser therapy (LLLT), thermal therapy, electromagnetic field therapy, and transcutaneous electrical nerve stimulation (TENS). LLLT did not reduce VAS scores, but it significantly reduced both the number of tender points and FIQ score. Thermal therapy was associated with significantly reduced VAS scores, tender points, and FIQ scores. Electromagnetic field therapy was associated with significantly reduced VAS score and FIQ score. TENS significantly reduced VAS scores.

Conclusion

Our analyses revealed that thermal therapy and LLLT had a partial effect on pain relief in FM patients, and this beneficial effect may have a positive influence on FM patients' health status.

Impact of a socio-educational intervention to improve the quality of life of patients with fibromyalgia: A quasi-experimental design

OBJECTIVE

To evaluate the impact of a socio-educational intervention to improve the quality of life of patients with fibromyalgia.

METHOD

Out of 132 eligible candidates, 128 patients participated with a diagnosis of fibromyalgia (ACR 1990/2010), over 18 years of age, who did not have cognitive problems or mental disorders in acute phase and lived in the catchment area of the participating CAPs. The patients underwent intervention for 5 weeks to strengthen self-management of pain and improve quality of life. Socio-demographic variables, satisfaction and quality of life (SF-36) were studied. Pre-post measurements were made on the 128 participants and follow-up at 2 months on 120 (8 did not agree to be contacted).

RESULTS

Comparing the pre-post-intervention scores (non-parametric Wilcoxon test), it was found that 71.09% reported a higher perception of quality of life in the Mental health domain and lower percentage of improvement (28.91%) in the Physical role domain. When comparing pre-post-follow-up scores (Friedman's test), mean perception improved in all domains and remained at 2-month follow-up (P<.001). Finally, the average satisfaction with the intervention received was 90.55% (SD 9.86; min. 41, max. 100).

CONCLUSIONS

When assessing the impact of the intervention, there was an improvement in the post and follow-up scores. This finding is largely due to the fact that the intervention strengthens the patient's self-mastery of their abilities to control pain and improve their perception of quality of life.

Living With a Contested, Stigmatized Illness: Experiences of Managing Relationships Among Women With Fibromyalgia

This study focuses on the negotiation of relationships among women living with the chronic illness fibromyalgia. Twenty in-depth, semistructured interviews were conducted with women diagnosed with fibromyalgia. Drawing from interactional and constructionist perspectives, the analysis focuses on participants' approaches to communicating with others about their illness, the reactions of others to their experiences, and participants' strategies to manage stigma. Participants attempted to describe their illness experience to others through direct and educational approaches. Often, in the management of their relationships with close family and friends, there was an unspoken awareness of illness effects, and social support was offered. However, disbelief and a lack of understanding often led participants to avoid social interactions in the attempt to hide from the stigma associated with an invisible and contested illness.

Work Ability in Fibromyalgia: An Update in the 21st Century

BACKGROUND

Fibromyalgia (FM) is characterized by persistent widespread pain, increased pain sensitivity and tenderness. People with FM also report activity limitations and impaired work ability.

OBJECTIVE

This article aims to compile the findings of recently published research on work ability in people with fibromyalgia, and to present how work ability is influenced by various aspects.

METHODS

A systematic search of the literature published from the year 2000 and onwards was conducted. Thirtyfour articles were included in the review.

RESULT

Symptom severity was found to influence work ability in people with FM. Physically demanding jobs and work tasks were especially troublesome and were reported to constitute higher risks pof work disability. Working people with FM seemed to hold a careful balancing act to manage the risk of overload where well-functioning strategies such as making a career change, working part-time, and developing personal skills were necessary for managing work, in the short- and long term. The support of management and colleagues enabled people with FM to manage the risk of overload at work. Treatment studies evaluating work disability as outcome in FM are scarce. None of the included studies presented any effects on measures of sick-leave or work disability compared with a control group.

CONCLUSION

More studies of treatment effects on outcomes related to work ability in people with FM, and more longitudinal studies to explore long-term effects of symptoms on work ability and sick leave, are needed in order to be able to plan evidence based rehabilitation to improve or maintain work ability in people with FM.

Individuals’ Descriptions of Living With Fibromyalgia

Fibromyalgia (FM) is a chronic pain syndrome with no known etiology, cure, prognosis, or clear diagnostic criteria. This interpretive descriptive study was focused on the experience of living with FM. Using a constant comparative inductive analytic method, the researcher collected and analyzed data from in-depth, semistructured interviews with eight participants. This study’s findings offer insights into the experience of living with and managing FM and identify social, policy, and health care issues that profoundly affect those suffering from it. Participants believe that people with FM would benefit if more health care professionals, as well as family and friends, would validate their condition and provide them with better support. More research could clarify ways in which health care providers may provide more effective interventions, appropriate care, and ongoing support for those affected with FM.

Decrease of fear avoidance beliefs following person-centered progressive resistance exercise contributes to reduced pain disability in women with fibromyalgia: secondary exploratory analyses from a randomized controlled trial

Background

Fibromyalgia (FM) is characterized by persistent widespread pain, increased pain sensitivity and tenderness. Women with FM also report disability, in terms of negative consequences on activities of daily living. Our recent randomized controlled trial (RCT) is the first study of resistance exercise to show positive effects on pain disability. The resistance exercise program of our RCT emphasized active involvement of participants in planning and progression of the exercise, using the principles of person-centeredness, to support each participant’s ability to manage the exercise and the progress of it. The aim of this sub-study was to investigate explanatory factors for reduced pain disability in women with FM participating in a 15-week person-centered progressive resistance exercise program.

Methods

A total of 67 women with FM were included in this sub-study of an RCT examining the effects of person-centered progressive resistance exercise performed twice a week for 15 weeks. Tests of physical capacity and health-related questionnaires were assessed at baseline and after the intervention period. Multivariable stepwise regression was used to analyze explanatory factors for improvements in pain disability.

Results

Reduced pain disability was explained by higher pain disability at baseline together with decreased fear avoidance beliefs about physical activity (R² = 28, p = 0.005). The improvements in the disability domains of recreation and social activity were explained by decreased fear avoidance beliefs about physical activity together with higher baseline values of each disability domain respectively (R² = 32, p = 0.025 and R² = 30, p = 0.017). The improvement in occupational disability was explained by higher baseline values of occupational disability (R² = 19, p = 0.001).

Conclusion

The person-centered resistance exercise intervention, based on principles of self-efficacy, had a positive effect on recreational, social and occupational disability. The reduced pain disability seemed to be mediated by decreased fear avoidance beliefs. Age, symptom duration, pain intensity, and muscle strength at baseline had no explanatory value for reduced pain disability, indicating that the person-centered resistance exercise program has the potential to work for anyone with FM who has interest in physical exercise.

The trial was registered on October 21, 2010 with ClinicalTrials.gov identification number: NCT01226784.

Adjudication of fibromyalgia syndrome: challenges in the medicolegal arena

The medicolegal challenges surrounding fibromyalgia (FM) arise from the subjectivity of symptoms, causal attribution and reported symptoms sufficiently severe to cause disablement. In the present article, the authors have endeavoured to provide clarification of some current issues by referencing the current literature, including the 2012 Canadian Fibromyalgia Guidelines. While FM is accepted as a valid condition, its diagnosis is vulnerable to misuse due to the subjectivity of symptoms. Without a defining cause, a physical or psychological event may be alleged to trigger FM, but adjudication of causation must be prudent. Although some individuals may experience severe symptoms, the prevalent societal concept of disablement due to FM must be tempered with the knowledge that working contributes to psychosocial wellbeing. Evidence provided in the present report may assist the courts in reaching decisions concerning FM.

2012 Canadian Guidelines for the diagnosis and management of fibromyalgia syndrome: executive summary

BACKGROUND

Recent neurophysiological evidence attests to the validity of fibromyalgia (FM), a chronic pain condition that affects >2% of the population.

OBJECTIVES

To present the evidence-based guidelines for the diagnosis, management and patient trajectory of individuals with FM.

METHODS

A needs assessment following consultation with diverse health care professionals identified questions pertinent to various aspects of FM. A literature search identified the evidence available to address these questions; evidence was graded according to the standards of the Oxford Centre for Evidence-Based Medicine. Drafted recommendations were appraised by an advisory panel to reflect meaningful clinical practice.

RESULTS

The present recommendations incorporate the new clinical concepts of FM as a clinical construct without any defining physical abnormality or biological marker, characterized by fluctuating, diffuse body pain and the frequent symptoms of sleep disturbance, fatigue, mood and cognitive changes. In the absence of a defining cause or cure, treatment objectives should be patient-tailored and symptom-based, aimed at reducing global complaints and enhancing function. Healthy lifestyle practices with active patient participation in health care forms the cornerstone of care. Multimodal management may include nonpharmacological and pharmacological strategies, although it must be acknowledged that pharmacological treatments provide only modest benefit. Maintenance of function and retention in the workforce is encouraged.

CONCLUSIONS

The new Canadian guidelines for the treatment of FM should provide health professionals with confidence in the complete care of these patients and improve clinical outcomes.

Canadian Pain Society and Canadian Rheumatology Association recommendations for rational care of persons with fibromyalgia: a summary report

OBJECTIVE

To summarize the development of evidence-based guidelines for the clinical care of persons with fibromyalgia (FM), taking into account advances in understanding of the pathogenesis of FM, new diagnostic criteria, and new treatment options.

METHODS

Recommendations for diagnosis, treatment, and patient followup were drafted according to the classification system of the Oxford Centre for Evidence-Based Medicine, and following review were endorsed by the Canadian Rheumatology Association and the Canadian Pain Society.

RESULTS

FM is a polysymptomatic syndrome presenting a spectrum of severity, with a pivotal symptom of body pain. FM is a positive clinical diagnosis, not a diagnosis of exclusion, and not requiring specialist confirmation. There are no confirmatory laboratory tests, although some investigation may be indicated to exclude other conditions. Ideal care is in the primary care setting, incorporating nonpharmacologic and pharmacologic strategies in a multimodal approach with active patient participation. The treatment objective should be reduction of symptoms, but also improved function using a patient-tailored treatment approach that is symptom-based. Self-management strategies combining good lifestyle habits and fostering a strong locus of control are imperative. Medications afford only modest relief, with doses often lower than suggested, and drug combinations used according to clinical judgment. There is a need for continued reassessment of the risk-benefit ratio for any drug treatment. Outcome should be aimed toward functioning within a normal life pattern and any culture of disablement should be discouraged.

CONCLUSION

These guidelines should provide the health community with reassurance for the global care of patients with FM with the aim of improving patient outcome by reducing symptoms and maintaining function.

Characteristics of suitable work from the perspective of patients with fibromyalgia

OBJECTIVES

The evaluation of work ability of patients with FM is difficult. Our aim was to investigate the characteristics of suitable work from the perspective of patients with FM.

METHODS

Interviews with patients yielded statements about characteristics of suitable work. Patients individually sorted these statements according to similarity. Hierarchical cluster analysis was applied to these sortings.

RESULTS

The hierarchical structure included 74 characteristics of suitable work. The 10 clusters at the lowest level included (i) recovery opportunities, (ii) pace of work, (iii) not too high workload, (iv) keeping energy for home and free time, (v) match between work and capabilities, (vi) development opportunities, (vii) understanding from colleagues, (viii) help from colleagues, (ix) support from management and (x) work agreements with management.

CONCLUSIONS

According to patients with FM, suitable work is paced in such a way that one can perform the job well and with satisfaction while keeping energy for home and free time and having acknowledgement and help from management and colleagues. The brief suitable work checklist that is provided can help patients with FM to negotiate with employers and job professionals to improve the match between job demands and capabilities.

Perfil de humor de mulheres com fibromialgia

OBJETIVO: O objetivo deste estudo foi verificar o perfil dos estados de humor de mulheres com fibromialgia, bem como analisar sua associação com características sociodemográficas e clínicas. MÉTODOS: Cento e seis participantes responderam ao Questionário Sociodemográfico e Clínico (QSDC) e à Escala de Humor de Brunel (BRUMS). O QSDC é constituído por perguntas sobre dados pessoais e aspectos clínicos, enquanto o BRUMS avalia o humor por meio de seis fatores, a saber: tensão, depressão, raiva, vigor, fadiga e confusão mental. Os dados foram tratados com estatística descritiva e por meio dos testes de Kruskal-Wallis e Mann-Whitney. RESULTADOS: As variáveis negativas do humor estiveram em níveis elevados, em especial a tensão, a depressão, a fadiga e a confusão mental, enquanto o vigor esteve baixo. Verificou-se ainda que as participantes mais jovens que trabalham com diagnóstico de depressão e, principalmente, as que possuíam maior número de sintomas relacionados à fibromialgia apresentavam humor mais deprimido do que seus pares. CONCLUSÃO: Mulheres com fibromialgia apresentaram tendência de humor deprimido, sendo que essa característica se apresentou associada a fatores sociodemográficos e clínicos.

Long-term sick-leavers with fibromyalgia: Comparing their multidisciplinarily assessed characteristics with those of others with chronic pain conditions and depression

Objective:

The aim was to gain knowledge of fibromyalgia (FM) patients on long-term sick leave and with particular difficulties in resuming work, and to compare them with patients with myalgia, back or joint diagnoses, and depression.

Methods:

Patients were identified by and referred from social insurance offices and were multidisciplinarily examined by three board-certified specialists in psychiatry, orthopedic surgery and rehabilitation medicine. Ninety-two women were diagnosed with FM only. Three female comparison groups were chosen: depression, back/joint diagnoses, and myalgia.

Results and conclusions:

Ceaseless pain was reported by 73% of FM patients, 54% of back/joint diagnoses patients, 43% of myalgia patients, and 35% of depression patients. The distribution of pain (>50%) in FM patients was to almost all regions of the body, and in depression patients to the lower dorsal neck, upper shoulders and lumbosacral back but not in the anterior body. Reduced sleep was more evident in FM patients. FM patients did not meet more criteria for personality disorder than patients with the other somatic pain conditions. The most common dimension of “personality traits” of somatic pain conditions was the “obsessive compulsive” but at a level clearly below that indicating a personality disorder. More FM patients experienced disabilities, the most common being in the mobility and domestic-life areas.

Self-assessed physical function levels of women with fibromyalgia: a national survey

OBJECTIVE

We sought to determine the self-reported physical function level of women with fibromyalgia (FM).

METHODS

We performed a secondary analysis using data from an Internet-based survey posted on the National Fibromyalgia Association website. Data used for this study included women (n = 1,735) aged 31-78 years who reported being diagnosed with FM.

RESULTS

More than 25% of women reported having difficulty taking care of personal needs and bathing, and >60% reported difficulty doing light household tasks, going up/down 1 flight of stairs, walking (1/2) mile, and lifting or carrying 10 lbs. More than 90% of women reported having difficulty doing heavy household tasks, lifting or carrying 25 lbs, and doing strenuous activities. Women with lower functional ability reported higher levels of fatigue, pain, spasticity, depression, restless legs, balance problems, dizziness, fear of falling, and bladder problems.

CONCLUSIONS

The average woman in this sample reported having less functional ability related to activities of daily living and instrumental activities of daily living than the average community-dwelling woman in her 80s. Several symptoms/conditions were found to be associated with functional limitation in women with FM. Targeting these-singly or in clusters-may potentially be important in terms of future interventions.

Measuring health in patients with fibromyalgia: content comparison of questionnaires based on the International Classification of Functioning, Disability and Health

OBJECTIVE

To analyze the content of outcome measures commonly used to assess health in patients with fibromyalgia (FM) by linking the items of the instruments with the International Classification of Functioning, Disability and Health (ICF) in order to evaluate the adequacy of currently used measures.

METHODS

Questionnaires used in FM were identified in a structured literature search. All concepts included in the items of the questionnaires were linked to ICF categories, according to previously published linking rules, by 2 independent health professionals. The percentages of linked ICF categories addressing the different ICF components were calculated.

RESULTS

Generic and symptom-specific instruments were included. From the 296 items contained in all 16 instruments, 447 concepts were extracted and then linked to 52 ICF categories of the component body functions, 1 category of the component body structure, 40 categories of the component activities and participation, and 9 categories of the component environmental factors. More than half of the concepts identified were linked to body function, fewer were linked to activities and participation, and only concepts of 4 instruments were linked to the ICF component environmental factors.

CONCLUSION

Many concepts were linked to the categories in the ICF component body functions. While linking to the broad category, purportedly similar instruments often covered widely varying areas of function at more fine-grained levels of detail. Some categories, such as environmental factors, were barely covered by any of the instruments and might constitute an important aspect of health deserving better coverage and future development.

Young women with fibromyalgia in the United States and Sweden: perceived difficulties during the first year after diagnosis

PURPOSE

The major symptoms of fibromyalgia (FM)--pain, tiredness, disrupted sleep, and muscle weakness--severely impact everyday activities, including the paid work role of women who have had FM for a long time. There are no prospective studies on young and newly diagnosed women with FM. The aim of the present study was to describe and compare difficulties young and newly diagnosed women in Sweden and the United States experienced during their first year after diagnosis.

METHOD

Three interviews, 6 months apart, were conducted, with 49 Swedish and 45 US women between the ages of 18 and 39. Five open-ended questions were asked concerning physical, psychological and social difficulties and limitations, and factors that increased or decreased their difficulties and limitations. At interviews 2 and 3 the women were also asked about ways of preventing their difficulties. The answers were written down and analysed by a content analysis approach.

RESULTS

Consistent categories of difficulties were reported: symptoms, movements, activities, moods, social network, external factors and coping strategies. More US women were working outside their homes than were their Swedish counterparts and they expressed more difficulties compared with the Swedish women.

CONCLUSIONS

In general, difficulties decreased and coping strategies increased over the 1-year period in both groups of newly diagnosed, young women.

Antipolymer antibody is not associated with fibromyalgia in Korean female patients

To examine the levels of antipolymer antibody (APA) in Korean female patients with fibromyalgia (FM) and to determine whether the levels of APA correlate with FM severity. Serum samples from patients with FM (n = 69), patients with rheumatoid arthritis (RA) (n = 71), and controls (n = 75) were assayed for APA. All of the subjects were female, and the controls were age-matched healthy volunteers. FM tender point counts and scores were examined, and FM patients were asked to complete a Korean version of the Fibromyalgia Impact Questionnaire (FIQ), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). APA-positive samples were detected in five (7.2%) of the 69 FM patients, seven (9.9%) of the 71 RA patients, and four (5.3%) of the 75 controls. The prevalence of seropositivity and the level of APA in FM patients did not differ from those in RA patients and controls. The proportion positive for APA was not higher for FM patients with severe symptoms than for FM patients with mild symptoms. There was a negative association between the APA level and age. The APA level in FM patients was not correlated with age at diagnosis, age at symptom onset, disease duration, education, tender point counts and scores, FIQ, STAI, or BDI. The prevalence of APA in Korean FM patients was quite low. Owing to the low prevalence of APA in this study, the APA assay did not distinguish FM patients with severe symptoms from those with mild symptoms.

'A constant struggle': successful strategies of women in work despite fibromyalgia

PURPOSE

This study aimed to explore, and obtain increased knowledge of, the strategies used by working women with fibromyalgia regarding control of pain, fatigue and other symptoms.

METHOD

Qualitative methods with an emergent design were used. The informants were women with fibromyalgia who had participated in rehabilitation 6-8 years earlier, and were still in work. Diaries, focus groups and individual interviews were used for data collection. Content analysis and grounded theory were used for the analyses.

RESULTS

A model with three categories emerged. The core category 'constant struggle' contains eight sub-categories: enjoying life, taking care of oneself, positive thinking, setting limits, using pain as a guide, creative solutions, learning/being knowledgeable and 'walking a tightrope'. The category 'grieving process' was a prerequisite for managing the struggle and the category 'social support' contained what facilitated the struggle.

CONCLUSION

The informants fought a constant struggle against the symptoms and the consequences of their fibromyalgia. Their strategies were action-oriented and evinced a positive spirit. To have grieved and accepted their situation was a prerequisite for managing, and support from the family was a help in the struggle.

Physical and Psychological Variables That Influence Pain in Patients With Fibromyalgia

BACKGROUND

Fibromyalgia is a syndrome of chronic pain. Its etiology is unknown and treatment is not well defined.

PURPOSE

The purpose of this study was to determine the influence of specific variables on pain in 107 women with fibromyalgia.

METHODS

Data collection included two pain measurements administered by the researcher, four survey questionnaires self-administered by the participants (measuring activity, fatigue, depression, and demographic data), and three measures of physical fitness for flexibility, strength, and endurance.

FINDINGS

Fatigue, pelvic pain, and physical trauma explained 23% of the variance in sensory pain; activity, depression, and pelvic pain explained 23% of affective pain; and a flare-up of symptoms and depression explained 25% of the intensity of pain experienced by the participants.

CONCLUSION

Nurses should consider decreasing depression and fatigue and increasing activity so that fibromyalgia pain may be lessened during care.

Educating patients: self-management approaches

PURPOSE

To review and evaluate approaches to educating patients with fibromyalgia syndrome (FMS).

METHODS

A narrative literature review was undertaken to summarize the published literature on patient education for FMS patients.

RESULTS

A number of studies contain specific education strategies while others are combined with exercise or movement therapies or cognitive-behavioural therapy.

CONCLUSIONS

Self-efficacy provides an effective theoretical model from which to understand how patients change as a result of education strategies that focus on self-management. Programmes that combine education with cognitive-behavioural techniques and exercise are most effective in enhancing self-efficacy and decreasing symptoms of FMS.

Estrogen regulates adrenal medullary function producing sexual dimorphism in nociceptive threshold and beta-adrenergic receptor-mediated hyperalgesia in the rat

Epinephrine produces sexually dimorphic beta(2)-adrenergic receptor-mediated mechanical hyperalgesia, with male rats exhibiting greater hyperalgesia. Because female rats have higher plasma epinephrine levels, and beta-adrenergic receptor sensitivity is affected by chronic exposure to agonists, we tested the hypothesis that this sexual dimorphism is due to epinephrine-induced desensitization of beta(2)-adrenergic receptors. Following gonadectomy, epinephrine hyperalgesia, as measured by the Randall-Selitto paw-withdrawal test, was unchanged in male rats while in females it was increased. Prepubertal male and female rats do not demonstrate sexual dimorphism in either plasma epinephrine level or epinephrine-induced hyperalgesia. Adrenal medullectomy and adrenal denervation both significantly enhanced epinephrine hyperalgesia, but only in females. In contrast, the sexually dimorphic hyperalgesia induced by prostaglandin E(2), another agent that acts directly to sensitize primary afferent nociceptors, was not enhanced by adrenal medullectomy or denervation. Chronic administration of epinephrine in male rats, to produce plasma levels similar to those of gonad-intact females, significantly attenuated epinephrine-induced hyperalgesia, making it similar to that in females. These results strongly support the suggestion that estrogen regulates plasma epinephrine in female rats and differential sensitivity to beta(2)-adrenergic agonists accounts for the sexual dimorphism in epinephrine-induced hyperalgesia. Unexpectedly, regulation of adrenal medullary function by estrogen was also found to modulate baseline nociceptive threshold such that females had a lower nociceptive threshold.

The impact of a diagnosis of fibromyalgia on health care resource use by primary care patients in the UK: An observational study based on clinical practice

OBJECTIVE

To investigate the impact of a diagnosis of fibromyalgia (FM) in clinical practice on health care resource use in the UK.

METHODS

Rates of visits, prescriptions, referral, and diagnostic testing were estimated in patients who had been diagnosed as having FM between 1998 and March 2003 in UK primary care and compared with those in matched controls. Rates were calculated in 6-month intervals from 10 years before until 4 years after the FM diagnosis.

RESULTS

Patients (2260) were newly diagnosed as having FM; 81.3% were women. Their mean age was 49 years. FM patients had considerably higher rates of visits, prescriptions, and testing from at least 10 years prior to diagnosis compared with controls. By the time of diagnosis, FM patients had 25 visits and 11 prescriptions per year compared with 12 visits and 4.5 prescriptions per year in controls. Visit rates were highest for depression, followed by fatigue, chest pain, headache, and sleep disturbance. Following diagnosis, visits for most symptoms and health care use markers declined, but within 2-3 years, most visits rose to levels at or higher than those at diagnosis.

CONCLUSION

Primary care patients who had been diagnosed as having FM reported higher rates of illness and health care resource use for at least 10 years prior to their diagnosis, which suggests that illness behavior may play a role. Being diagnosed as having FM may help patients cope with some symptoms, but the diagnosis has a limited impact on health care resource use in the longer term, possibly because there is little effective treatment.

Quantifying pain threshold and quality of life of fibromyalgia patients

The most typical symptom of fibromyalgia (FM) is diffuse pain, and pain at specific points-tender points-is crucial for its diagnosis. By comparing healthy individuals and FM patients, this study was aimed at assessing pain and quality of life of Brazilian females with FM, while seeking for a correlation between pain threshold and quality of life. A total of 178 women were evaluated: 124 were FM patients and 54 were healthy women. Pain threshold at tender points was quantified by dolorimetry, and diffuse pain by means of the visual analogue scale (VAS); the Fibromyalgia Impact Questionnaire (FIQ) was used to evaluate quality of life. Statistical treatment of the data allowed for proposing two indexes: a pain threshold index (PT) and a quality of life one (QOL). PT is the lowest value among all pain thresholds measured at the 18 tender points; QOL is the mean of responses to the FIQ and VAS. Both indexes were tested and showed significant differences between the test and control groups. By pairing pain threshold values of each tender point in the test and control groups, it was found that the most sensitive points matched between the two groups, that is, the most sensitive anatomic spots in a healthy individual are also likely to be the most sensitive points in a person with FM. This suggests that a stimulus that provokes slight discomfort to a healthy person may produce more pain in FM patients--which may bear implications for FM clinical treatment. In this sample of Brazilian women, FM patients had both lower pain threshold and worse quality of life than healthy women.

Assessment of anxiety and quality of life in fibromyalgia patients

CONTEXT

Fibromyalgia is a syndrome characterized by chronic, diffuse musculoskeletal pain, and by a low pain threshold at specific anatomical points. The syndrome is associated with other symptoms such as fatigue, sleep disturbance, morning stiffness and anxiety. Because of its chronic nature, it often has a negative impact on patients' quality of life.

OBJECTIVE

To assess the quality of life and anxiety level of patients with fibromyalgia.

TYPE OF STUDY

Cross-sectional.

SETTING

Rheumatology outpatient service of Hospital das Clínicas (Medical School, Universidade de São Paulo).

METHODS

This study evaluated 80 individuals, divided between test and control groups. The test group included 40 women with a confirmed diagnosis of fibromyalgia. The control group was composed of 40 healthy women. Three questionnaires were used: two to assess quality of life (FIQ and SF-36) and one to assess anxiety (STAI). They were applied to the individuals in both groups in a single face-to-face interview. The statistical analysis used Student's t test and Pearson's correlation test (r), with a significance level of 95%. Also, the Pearson chi-squared statistics test for homogeneity, with Yates correction, was used for comparing schooling between test and control groups.

RESULTS

There was a statistically significant difference between the groups (p = 0.000), thus indicating that fibromyalgia patients have a worse quality of life and higher levels of anxiety. The correlations between the three questionnaires were high (r = 0.9).

DISCUSSION

This study has confirmed the efficacy of FIQ for evaluating the impact of fibromyalgia on the quality of life. SF-36 is less specific than FIQ, although statistically significant values were obtained when analyzed separately, STAI showed lower efficacy for discriminating the test group from the control group. The test group showed worse quality of life than did the control group, which was demonstrated by both FIQ and SF-36. Even though STAI was a less efficient instrument, it presented significant results, showing that fibromyalgia patients presented higher levels of anxiety, both on the state and trait scales. Thus, patients with fibromyalgia had higher levels of tension, nervousness, preoccupation and apprehension, and higher propensity towards anxiety.

CONCLUSION

The three instruments utilized showed efficiency in evaluating fibromyalgia patients. FIQ was found to be the most efficient instrument for discriminating and assessing the impact of fibromyalgia on their quality of life. It can be concluded that such patients have a worse quality of life and higher levels of anxiety.

The Quality of Life Scale (QOLS): reliability, validity, and utilization

The Quality of Life Scale (QOLS), created originally by American psychologist John Flanagan in the 1970's, has been adapted for use in chronic illness groups. This paper reviews the development and psychometric testing of the QOLS. A descriptive review of the published literature was undertaken and findings summarized in the frequently asked questions format. Reliability, content and construct validity testing has been performed on the QOLS and a number of translations have been made. The QOLS has low to moderate correlations with physical health status and disease measures. However, content validity analysis indicates that the instrument measures domains that diverse patient groups with chronic illness define as quality of life. The QOLS is a valid instrument for measuring quality of life across patient groups and cultures and is conceptually distinct from health status or other causal indicators of quality of life.

Living in the shadow of fibromyalgic pain: the meaning of female partners' experiences

The aim of this study was to elucidate the meaning of being a female partner living with a man with fibromyalgic pain. Fourteen partners were interviewed about the meaning of their experiences, using a narrative approach. A phenomenological hermeneutic method, inspired by the French philosopher Ricoeur, was used to interpret the interview text. The structural analysis is presented in three major themes: struggling to give support and comfort, struggling to keep going on, and experiencing lack of understanding and support. The findings elucidate that the meaning of living with a man with fibromyalgic pain meant living a life strongly influenced by the man's illness and in the shadow of the man's pain. Taking daily life for granted was interrupted and restricted family and social life. Prominent in this study was the frustration partners felt as a result of men's reluctance to communicate. This led to feelings of being excluded from men's emotions. The responsibility day in and day out meant that women's own caring and tenderness were replaced, which brought about an almost constant sense of fatigue. Women became drained by the long duration of men's illness. This gave them a feeling of being alone, although they were a couple. Gaining comfort outside the family helped partners to reach a new insight and appreciation for life, which was viewed from a renewed perspective. This involved feelings of both togetherness and separateness in the relationship. The findings also consider the lack of support from the health care system for female partners living with men with fibromyalgic pain.

Coping with fibromyalgia. A qualitative study

This study aims to describe, from the perspective of patients with fibromyalgia themselves, their experiences of having to live with chronic pain and how they manage their situation. The sample consists of 22 female patients (22-60 years). Open-ended in-depth interviews were analysed by a method directed by the tradition of Grounded Theory. Three descriptive categories were grounded in the data, labelled subjective pain language, diversified pain coping, and pain communication. These descriptive categories formed the higher-order, or core, concept preoccupied with pain. Having to live with chronic pain seems to include that the sufferer becomes self-centred and preoccupied with the pain: the pain is mostly present and affects every aspect of life, leading to a continuous awareness of and coping with the pain. Pain tends to interrupt normal life, demands attention and is difficult to disengage from. Although coping should not be evaluated in terms of good and bad, passivity, escape behaviours, and resignation/catastrophizing, which dominated in the present study sample, might affect social and psychological functioning negatively. Patients with fibromyalgia might benefit from psychological support in coping with their pain and from reinforcement of healthy behaviours.

Factors of importance for work disability in women with fibromyalgia: an interview study

OBJECTIVE

Fibromyalgia symptoms such as continuous pain, tiredness, hyperalgesia, and allodynia limit gainful employment. The present study examines which factors influence the decision to remain in a work role for women with fibromyalgia. This information is important for the individual and for public finances.

METHODS

Qualitative interviews were performed with 39 women, 19 of whom were gainfully employed and 20 who had stopped working. The transcribed interviews were analyzed and divided into categories and subcategories.

RESULTS

Four categories appear, at societal and individual levels, that were regarded as important by the women for remaining in a work role.

CONCLUSIONS

The ability to remain at work depends not only on limitations in work capacity, but also on the capacity of society to adjust work environments and work tasks. More individual solutions are needed to allow women with fibromyalgia to maintain work roles.

The meaning of fatigue and tiredness as narrated by women with fibromyalgia and healthy women

1. The aim of this study was to elucidate the meaning of fatigue and tiredness as narrated by women with fibromyalgia (FM) and healthy women. Twenty-five women with FM were interviewed with a narrative approach about the meaning of the lived experience of fatigue and tiredness. A reference group of 25 healthy women was interviewed about the same topic. 2. A phenomenological-hermeneutic method inspired by the French philosopher Ricoeur was used to interpret the interview text. 3. The meaning of fatigue and tiredness was related differently by women with FM and healthy women. The findings are presented in four major themes for women with FM -- the body as a burden, an absent presence, an interfering obstacle and being in hope of alleviation -- and in one major theme for healthy women: needing recovery. 4. Women with FM narrated fatigue as making it obvious that I have a body, instead of I am my body; the lived body becomes urgently present, as an 'it'. Healthy women narrated tiredness as a natural phenomenon when they need recovery and time to rest. 5. The findings are interpreted in the light of the phenomenological work on the lived body by Leder, Toombs and Merleau-Ponty.

Struggling for a tolerable existence: the meaning of men's lived experiences of living with pain of fibromyalgia type

Chronic pain is a major health problem in Sweden because of its consequences in daily life. Fourteen men with fibromyalgia-type pain were interviewed regarding their experiences. A phenomenological hermeneutic method was used to interpret the transcribed interviews. Three major themes emerged: experiencing the body as an obstruction, being a different man, and striving to endure. Overall, the meaning of men's lived experience of chronic pain was experienced as change in the body, self, and relationships. Striving to live life required achieving balance during both calm and difficult phases of the illness--struggling for a tolerable existence. Information from this study could provide guidelines for health care staff members to give empathic and supportive care to men living with a long-term illness.

Transitions experienced by women with fibromyalgia

Fibromyalgia (FM) is a chronic pain syndrome the hallmarks of which are a chronic diffuse musculoskeletal pain, tender points, and fatigue. The majority of those who have FM are middle-aged women. The aim of this study was to illuminate the transitions experienced by women with FM. Twenty-five women with FM were interviewed about living with FM. The interviews were analyzed using thematic content analysis. The analysis revealed five categories; transitions in patterns of daily life, family life, social life, and working life, and learning to live with the changes brought about by FM. The categories were subsumed into one theme: FM as the choreographer of activity and relationships. The transitions experienced were illuminated in a core story. The experience of transitions is apparently something that is invisible to almost everyone except the women themselves. Paradoxically, the women described transitions in life due to the illness, but they felt that other people saw them as healthy. It is like living in two worlds simultaneously, the world of the sick and the world of the healthy.

Is fibromyalgia a distinct clinical syndrome?

The validity of the fibromyalgia syndrome (FMS) as a distinct clinical entity has been challenged for several reasons. Many skeptics express concern about the subjective nature of chronic pain, the subjectivity of the tender point (TeP) examination, the lack of a gold standard laboratory test, and the absence of a clear pathogenic mechanism by which to define FMS. Another expressed concern has been the relative nature of the pain-distress relationship in the rheumatology clinic. The apparently continuous relationship between TePs and somatic distress across a variety of clinical disorders is said to argue against FMS as a separate clinical disorder. The most aggressive challenges of the FMS concept have been from legal defenses of insurance carriers motivated by economic concerns. Other forms of critique have presented as psychiatric dogma, uninformed posturing, suspicion of malingering, ignorance of nociceptive physiology, and occasionally have resulted from honest misunderstanding. It is not likely that a few paragraphs of data and logic will cause an unbeliever to change an ingrained opinion. Therefore, this review describes the clinical manifestations of FMS, responds to some of the theoretic arguments against it, and discusses some possible pathophysiologic mechanisms by which FMS may develop and persist as a unique syndrome.

Is fibromyalgia a distinct clinical entity? Pain mechanisms in fibromyalgia syndrome. A myologist's view

The cause of muscle pain and allodynia may not be the same in all persons fulfilling the American College of Rheumatology (ACR) criteria for fibromyalgia syndrome. In the majority of patients the generalized pain is preceded by localized or regional pain, usually in the musculoskeletal system. In many patients with fibromyalgia there are findings compatible with tissue injury pain with pain mechanisms involving both the primary afferent neuron and the nociceptive system in the central nervous system. Evidence for these mechanisms is described.

Struggling for dignity: the meaning of women's experiences of living with fibromyalgia

Fibromyalgia (FM) is a common chronic pain syndrome with an obscure etiology, which mostly afflicts middle-aged women. In this study, 14 women with FM were interviewed about the meaning of living with the illness. A phenomenological-hermeneutic method was used to analyze and interpret the interview texts. The findings show that being a woman with FM means living a life greatly influenced by the illness in various ways. The women's experiences of living with FM were presented in three major interlaced themes: loss of freedom, threat to integrity, and a struggle to achieve relief and understanding. This study highlights the importance of meeting people suffering in illness with respect for their human dignity. The care of women with FM must empower the women to bring to bear their own resources so that they can manage to live with the illness.

How patients with fibromyalgia experience their symptoms in everyday life

BACKGROUND AND PURPOSE

Fibromyalgia syndrome (FMS) is characterized by diffuse widespread pain and fatigue. The purpose of this study was to search for a deeper knowledge of the way patients with FMS experience their symptoms in everyday life.

METHOD

Qualitative interviews, applying the phenomenological method, were used. The respondents were interviewed twice and asked to describe a typical day. Eleven Swedish women, aged 24-54 years, fulfilling the ACR criteria for FMS participated in the study. The duration of pain ranged from three to 20 years. Three patients worked full-time, six worked part-time and two did not work outside the home.

RESULTS

The effect of perceived symptoms on everyday life was considerable. Four different patterns of perceiving and managing symptoms were identified: Struggling: respondents who perceived that they managed their everyday life by mobilizing their physical and psychological strength to fight their pain and fatigue; Adapting: respondents who perceived that they managed their everyday life by planning their activities on the basis of their assumptions of limitations; In despair: respondents who were in despair as they could no longer cope with their pain and life situation; Giving up: respondents who had given up many activities of everyday life and felt that their symptoms dominated their life.

CONCLUSIONS

The study illuminates qualitative differences in FMS patients' experience and management of their symptoms in their everyday life. These differences ought to be considered when planning physiotherapy treatment.
