Psychological impact of fibromyalgia: current perspectives

Mindfulness-based stress reduction (MBSR) for fibromyalgia patients: The role of pain cognitions as mechanisms of change

BACKGROUND

Fibromyalgia (FM) is a pain condition characterized by physical and psychological difficulties. This randomized controlled trial aimed to evaluate the effects of a mindfulness-based stress reduction (MBSR) on FM patients and identify the role of two pain cognitions: psychological inflexibility in pain (PIPS) and pain catastrophizing (PCS), as mechanisms of change.

METHODS

95 FM patients (Mean ± SD: 49.18 ± 13.26 years) were randomly assigned to MBSR group therapy (n = 49) or a waitlist (WL) control group (n = 46). An adapted MBSR protocol for FM was employed. A series of measures were taken, covering FM symptoms, depression, perceived stress (PSS), PIPS and PCS. Three measurements were conducted: pre-intervention, post-intervention and 6-months follow up.

RESULTS

Compared to WL controls, the MBSR group showed greater improvements in FM symptoms (F(1,78) = 2.81, p < 0.05), PSS (F(1,78) = 4.38, p < 0.05) and Depression (F(1,78) = 21.12, p < 0.001), with mostly medium effect sizes. Improvements in PSS (F(2,68) = 7.75, p < 0.05) and depression (F(2,68) = 15.68, p < 0.05) remained stable over six months. The effect of MBSR on FM and PSS was mediated by one's reported change in PIPS. The effect of MBSR on depression was mediated by one's reported change in PCS.

CONCLUSIONS

These results reveal the significant therapeutic potential of MBSR for FM patients, due to the emphasis on non-judging and acceptance of negative inner states. Furthermore, this research identified two important pain-related cognitions as mechanisms of change, suggesting that MBSR contributes to cognitive change, which enables the reduction of physical and psychological distress.

The effect of earthquake on fibromyalgia: a comparison of patients on medication and without medication

INTRODUCTION / OBJECTIVES

Stressful events like earthquakes might worsen the symptoms of fibromyalgia, although the influence of medications on these consequences is yet uncertain. The objective of this study was to examine the influence of an earthquake on the symptoms of fibromyalgia and evaluate the impacts of medications used to treat fibromyalgia on the clinical picture.

METHOD

Ninety-five fibromyalgia patients were enrolled in a comparative study and divided into two groups: medication and non-medication. Three subcategories of medication groups were established: selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and gabapentinoid drugs (GDs). Before and after the earthquake, clinical evaluations were conducted using the Fibromyalgia Impact Questionnaire (FIQ), Hospital Anxiety and Depression Scale (HADS), and Jenkins Sleep Rating Scale (JSS). Statistical analyses were conducted to compare the scores before and after the earthquake and evaluate the differences between the groups.

RESULTS

Statistically significant increases were observed in FIQ, HADS-anxiety, HADS-depression, and JSS scores in the medication and non-medication groups before and after the earthquake comparisons (p < 0.05). Non-medication group reported significantly higher post-earthquake changes in FIQ, HADS-anxiety, HADS-depression, and JSS compared to the medication group (p < 0.05). While HADS-anxiety, HADS-depression, and JSS changes after the earthquake differed according to the drug subgroups (p < 0.05), no statistically significant difference was observed in FIQ values (p > 0.05). The highest scores were detected in the GD subgroup.

CONCLUSIONS

This study highlights the substantial impact of earthquakes on fibromyalgia patients. Medication use may assist in reducing the detrimental effects of stresses like earthquakes on fibromyalgia symptomatology. Future research with larger sample sizes and more extended follow-up periods is needed to explain these findings and optimize treatment regimens for fibromyalgia patients experiencing significant stressors.

Large language model-driven sentiment analysis for facilitating fibromyalgia diagnosis

BACKGROUND

Fibromyalgia (FM) is a complex disorder with widespread pain and emotional distress, posing diagnostic challenges. FM patients show altered cognitive and emotional processing, with a preferential allocation of attention to pain-related information. This attentional bias towards pain cues can impair cognitive functions such as inhibitory control, affecting patients' ability to manage and express emotions. Sentiment analysis using large language models (LLMs) can provide insights by detecting nuances in pain expression. This study investigated whether open-source LLM-driven sentiment analysis could aid FM diagnosis.

METHODS

40 patients with FM, according to the 2016 American College of Rheumatology Criteria and 40 non-FM chronic pain controls referred to rheumatology clinics, were enrolled. Transcribed responses to questions on pain and sleep were machine translated to English and analysed by the LLM Mistral-7B-Instruct-v0.2 using prompt engineering targeting FM-associated language nuances for pain expression ('prompt-engineered') or an approach without this targeting ('ablated'). Accuracy, precision, recall, specificity and area under the receiver operating characteristic curve (AUROC) were calculated using rheumatologist diagnosis as ground truth.

RESULTS

The prompt-engineered approach demonstrated accuracy of 0.87, precision of 0.92, recall of 0.84, specificity of 0.82 and AUROC of 0.86 for distinguishing FM. In comparison, the ablated approach had an accuracy of 0.76, precision of 0.75, recall of 0.77, specificity of 0.75 and AUROC of 0.76. The accuracy was superior to the ablated approach (McNemar's test p<0.001).

CONCLUSION

This proof-of-concept study suggests LLM-driven sentiment analysis, especially with prompt engineering, may facilitate FM diagnosis by detecting subtle differences in pain expression. Further validation is warranted, particularly the inclusion of secondary FM patients.

Psychological Distress in Women with Fibromyalgia: The Roles of Body Appreciation, Self-Compassion, and Self-Criticism

BACKGROUND

While past research detected a direct link between symptoms of fibromyalgia (FM) and psychological distress, body appreciation was suggested as a viable mediator of this link. The aim of the present study was to further develop an explanatory model for the effect of FM on women's psychological distress and identify possible protective and risk factors. Specifically, it was hypothesized that self-compassion would moderate the indirect effect of body appreciation and self-criticism on psychological distress in women with FM.

METHOD

This study comprised a total of 293 women, aged 20-68 (M = 34.8, SD = 12.3), of whom 146 were women with FM and 147 were heathy controls. All the women completed questionnaires regarding demographic characteristics, depression (PHQ-9), anxiety (GAD-7), self-criticism (DEQ-SC), body appreciation (BAS2), and the self-compassion scale (SCS).

RESULTS

A moderated serial mediation model demonstrated lower body appreciation in participants with FM compared to controls. These lower levels of body appreciation, together with lower levels of self-compassion, were associated with greater self-criticism and, consequently, higher levels of psychological distress.

CONCLUSIONS

The results emphasize the role of self-compassion as a protective mechanism against psychological distress among women with FM. Future studies should further investigate the effect of self-compassion-focused interventions on patients with FM.

Social Determinants and Consequences of Pain: Toward Multilevel, Intersectional, and Life Course Perspectives

Despite wide endorsement of a biopsychosocial framework for pain, social aspects of pain remain rarely addressed in the context of pain prevention and management. In this review, we aim to 1) examine the broad scope of social determinants and consequences of pain and their interactions across multiple levels of organization, and 2) provide a framework synthesizing existing concepts and potential areas for future work on social aspects of pain, drawing upon socioecological, intersectional, and life course approaches. Integrating interdisciplinary theory and evidence, we outline pathways through which multilevel social factors and pain may affect each other over time. We also provide a brief summary of intrapersonal aspects of pain, which are thought to operate at the interface between individuals and the social context. Progressing from micro- to macrolevel factors, we illustrate how social determinants of pain can directly or indirectly contribute to pain experiences, expression, risk, prognosis, and impact across populations. We consider 1) at the interpersonal level, the roles of social comparison, social relatedness, social support, social exclusion, empathy, and interpersonal conflict; 2) at the group or community level, the roles of intimacy groups, task groups, social categories, and loose associations; and 3) at the societal level, the roles of political, economic, and cultural systems, as well as their policies and practices. We present examples of multilevel consequences of pain across these levels and discuss opportunities to reduce the burden and inequities of pain by expanding multilevel social approaches in pain research and practice. PERSPECTIVE: Despite wide endorsement of a biopsychosocial framework for pain, social aspects of pain are often unclearly defined, hindering their use in pain prevention, management, and research. We summarize the scope of social aspects of pain and provide a framework synthesizing existing concepts and potential areas for future work.

The (in)visibility of fibromyalgia through its symptoms and the challenges of its diagnosis and therapy

OBJECTIVE

To analyze the social representations of fibromyalgia based on its symptoms and their influences on diagnosis and therapy.

METHODS

Qualitative research with the application of the Theory of Social Representations and snowball sampling method. Semi-structured interviews were conducted with 30 adults diagnosed with fibromyalgia in the city of Rio de Janeiro, Brazil, between April 2020 and January 2021. Statistical and lexicographical analysis was performed using Alceste software.

RESULTS

Pain, as a subjective phenomenon, complicates its legitimacy, diagnosis, and therapy, enhancing suffering. Insufficient information generates judgments, stereotypes, and prejudices.

FINAL CONSIDERATIONS

Stigmas, prejudices, the variety and invisibility of symptoms make it difficult to objectify the disease within the Cartesian-biomedical frameworks, generating diagnostic pilgrimage, mistakes, and challenges in treatment. Such representations hinder relationships and the management of the disease. Deconstructing them is a way to better care for those with fibromyalgia. Raising awareness and spreading qualified information are important allies.

Exploring Biopsychosocial Stress Markers in Women With Fibromyalgia

BACKGROUND

Identification of fibromyalgia has been a challenge for healthcare professionals due to the lack of a clinical biomarker. A well-supported integrative hypothesis holds that this condition is a chronic pain problem partly caused by long-term dysregulation of stress response. Therefore, stress assessment from a biopsychosocial perspective may be a useful approach to recognizing fibromyalgia.

PURPOSE

A cross-sectional case-control study was conducted to explore stress markers from a multidimensional perspective, including heart rate variability (as a biomarker of stress) as well as psychological distress and social stress.

METHODS

Forty-seven women with fibromyalgia were recruited from support groups and another 47 were recruited as matched pain-free controls. Comparison and discriminant function analyses were performed.

RESULTS

The data support the goodness of biopsychosocial stress markers in women with fibromyalgia, resulting in the identification of between 70% and 74.5% of fibromyalgia cases (sensitivity) and 85%-87% pain-free controls (specificity), with medium-high levels of fit (λ = 0.58 and λ = 0.59; p < .00). Women with fibromyalgia were characterized by high levels of psychological distress, social stress (disorder levels), and autonomic dysregulation. Although distress and social stress had a greater weight in discriminant functions, dysregulation in terms of low parasympathetic activity and high sympathetic activity at rest was also relevant.

CONCLUSIONS

A biopsychosocial approach to stress with an objective biomarker such as heart rate variability may be a useful tool to identify and manage FM.

Perceived Stress and Life Stressors in Adults with and without Fibromyalgia

Chronic medical conditions (i.e., chronic widespread pain) may contribute to accelerated/accentuated aging, such that middle-aged individuals with comorbidities may actually show increased declines in physical, cognitive, and mental health compared to normal aging adults. We examined perceived stress, life stressors, and depression in adults with and without fibromyalgia, a chronic pain condition. Ninety-four participants (52% with fibromyalgia, 78% female) aged 50 to 93 were administered the Perceived Stress Scale, Social Readjustment Rating Scale, and Beck Depression Inventory. Hierarchical regression analyses were conducted: the predictor variables were age, gender, fibromyalgia status, depression, and fibromyalgia-depression interaction. The interaction term significantly predicted perceived stress, but not life stressors. Depression significantly predicted stress for Social Readjustment Rating Scale measures after controlling for covariates. Significant associations were found between perceived stress and life stressors in all participants. In addition, those with fibromyalgia were significantly more likely to report higher levels of stress above standardized scores on both the Perceived Stress Scale and the Social Readjustment Rating Scale. Finally, depressive symptoms played a more significant role than fibromyalgia status in predicting life stressors. Conclusions: These findings emphasize the importance of assessing different types of stress and stressors in individuals with chronic widespread pain and/or depression in mid-life and beyond to better treat individuals with these conditions.

Emotional experiences and gender roles of men with fibromyalgia syndrome: a cross-cultural qualitative study

Introduction

Gender roles may impact men with fibromyalgia, causing a high number of negative emotional states and affective disorders. There are few studies that detect men's high emotional suffering. This study examined the emotional experience of men with fibromyalgia.

Methods

A qualitative cross-cultural study utilized inductive thematic analysis was performed at the Fibromyalgia and Chronic Fatigue Unit Santa Maria University Hospital in Spain, the Fibromyalgia and Chronic Fatigue Clinic at Mayo Clinic in the US, and volunteers from the Winneshiek County in the US A total of 17 participants, 10 men from Spain and 7 men from the US were included.

Results

Three themes related to feelings/emotions emerged: (1) psychological level; (2) social level; and (3) physical level. Men with fibromyalgia from Spain and the US experienced many negative emotions. Men often experience negative emotions that are worsened by common misunderstandings and social biases/stigma about their condition.

Conclusion/implications

A proper assessment of emotions when evaluating the global health of men with fibromyalgia as well as the provision of emotional support would improve their mental health and therefore their overall physical health. Emotional management should be incorporated into all treatment protocols for fibromyalgia, especially for men given the gender stigma. Health policies designed by legislators, policymakers, and support agencies must be accompanied by education in gender role concepts to improve the emotions of men with FMS. The mass media will be essential for the disclosure of the emotional suffering of male patients so that society might better understand them.

Investigation of patients' understanding of fibromyalgia: Results from an online qualitative survey

OBJECTIVE

An important component to effective fibromyalgia treatment is patient education about the condition. While previous educational interventions have been developed, these have not incorporated the lived experiences of patients and may not address common misunderstandings among those who may benefit from these interventions. This study aimed to explore understanding, confusion, and gaps in knowledge about fibromyalgia among those who report a fibromyalgia diagnosis.

METHODS

Participants were recruited via clinic flyers and the social media page of a chronic pain research laboratory. Participants completed an online survey that assessed their knowledge of fibromyalgia via open-ended questions. Responses were analyzed via thematic analysis to identify, analyze, and report themes.

RESULTS

Thirty-eight participants completed the survey (63% female, ages 18-68). Common themes that arose from patients included being unsure of the cause of their fibromyalgia, frustration and confusion about the random/variable nature of symptoms and flares, feeling that their condition was invisible, and desiring more information on available treatments.

CONCLUSION

Participants in this study expressed confusion about many aspects of fibromyalgia and a desire for more understanding from others in their life about this condition.

PRACTICE IMPLICATIONS

Future interventions would benefit from tailoring fibromyalgia education to the specific knowledge and lived experiences of patients.

Severe fibromyalgia alleviated by the unique muscle relaxation method of applying low force: A case report

RATIONALE

Fibromyalgia (FM) is characterized by idiopathic persistent chronic pain in the ligaments or musculoskeletal system, and more than half of the patients with FM might have migraine headaches. Direct musculoskeletal intervention could be a non-pharmacological management to relieve symptoms. However, patients with severe FM often have intense pain from only a soft touch, thereby rendering musculoskeletal intervention challenging.

PATIENT CONCERNS

A 47-year-old man had progressing intense pain, and this affected his everyday life. There were no abnormal physical findings on laboratory examination such as levels of complement, antinuclear antibodies, and C-reactive protein, which were within normal limits. Magnetic resonance imaging did not indicate abnormalities.

DIAGNOSES, INTERVENTIONS, AND OUTCOMES

The patient satisfied the American College of Rheumatology criteria. Finally, we made a final diagnosis of fibromyalgia. The therapeutic intervention of Kanshoho, the unique muscle relaxation technique with low force, relieved his pain.

LESSONS

If Kanshoho is carefully applied in a state of hospitalization under surveillance by an experienced physician, it could be a promising muscle relaxation method. Relaxing the trapezius muscle and reducing its intramuscular pressure might be key in treating patients with severe FM. However, it needs elucidation of its mechanism.

The relationship between metacognition, anger, and pain intensity among fibromyalgia patients: a serial mediation model

Fibromyalgia is a burdensome pain causing patients a very negative emotional state that can worsen their clinical profile, perceived disability, and treatment outcomes. In particular, anger can negatively affect pain and patient adjustment to the disease. Recent studies suggest that metacognitions and anger rumination can negatively affect anger, which in turn can amplify the intensity of pain. This study aims to investigate whether anger rumination and state anger serially mediate the relationship between metacognitions and the intensity of pain. The study included 446 subjects who: declared having received a fibromyalgia diagnosis by a rheumatologist/pain physician; completed measures of metacognitions, anger rumination, state-anger, and pain intensity. The serial mediation analysis was conducted using Hayes' PROCESS macro (Model 6). Negative beliefs about worry and beliefs about the need to control thoughts indirectly influenced the intensity of pain through two significant mediating pathways: state-anger and anger rumination to state-anger. Cognitive self-consciousness affected pain intensity directly (β = .11, p < .05) and indirectly through two significant mediating pathways: state-anger and anger rumination to state-anger. This study highlights the role of serial mediation of anger rumination and state-anger in the relationship between metacognitions and pain intensity in the field of fibromyalgia. Our work introduces new targets for anger management interventions for patients with fibromyalgia. Such interventions could be effectively addressed with a metacognitive approach considering its specific focus on dysfunctional metacognitive beliefs and repetitive negative thinking.

Automated characterization and detection of fibromyalgia using slow wave sleep EEG signals with glucose pattern and D'hondt pooling technique

Fibromyalgia is a soft tissue rheumatism with significant qualitative and quantitative impact on sleep macro and micro architecture. The primary objective of this study is to analyze and identify automatically healthy individuals and those with fibromyalgia using sleep electroencephalography (EEG) signals. The study focused on the automatic detection and interpretation of EEG signals obtained from fibromyalgia patients. In this work, the sleep EEG signals are divided into 15-s and a total of 5358 (3411 healthy control and 1947 fibromyalgia) EEG segments are obtained from 16 fibromyalgia and 16 normal subjects. Our developed model has advanced multilevel feature extraction architecture and hence, we used a new feature extractor called GluPat, inspired by the glucose chemical, with a new pooling approach inspired by the D'hondt selection system. Furthermore, our proposed method incorporated feature selection techniques using iterative neighborhood component analysis and iterative Chi2 methods. These selection mechanisms enabled the identification of discriminative features for accurate classification. In the classification phase, we employed a support vector machine and k-nearest neighbor algorithms to classify the EEG signals with leave-one-record-out (LORO) and tenfold cross-validation (CV) techniques. All results are calculated channel-wise and iterative majority voting is used to obtain generalized results. The best results were determined using the greedy algorithm. The developed model achieved a detection accuracy of 100% and 91.83% with a tenfold and LORO CV strategies, respectively using sleep stage (2 + 3) EEG signals. Our generated model is simple and has linear time complexity.

Measurement of event-related potentials from electroencephalography to evaluate emotional processing in Fibromyalgia Syndrome: A systematic review and meta-analysis

OBJECTIVE

The present systematic review and meta-analysis intended to: 1) determine the extent of abnormalities in emotional processing linked to emotional event-related potentials (ERPs) in Fibromyalgia Syndrome (FMS) and 2) integrate data from similar emotional tasks into a meta-analysis to clearly demonstrate the scientific and clinical value of measuring emotional ERPs by electroencephalography (EEG) in FMS.

METHODS

A systematic review and meta-analysis of studies comparing emotional processing indicated by ERPs in FMS patients and healthy controls was conducted. Fifteen articles were included in the systematic review after applying the eligibility criteria.

RESULTS

Nine articles demonstrated disturbances in emotional processing in FMS. These emotional disturbances were distributed over the whole range of ERP latencies, mainly over central, parietal, temporal and occipital areas. Despite of this, quantitative analysis revealed only significant differences in N250 and LPP/LPC between FMS patients and healthy controls, with smaller LPP/LPC and greater N250 seen in FMS.

DISCUSSION

N250 and LPP/LPC seem to be the ERPs with the greatest potential to determine emotional alterations in FMS. These ERPs are related to complex cognitive processes such as decoding features relevant to affect recognition (N250) as well differentiation between emotions, persistent engagement, conflict resolution or evaluation of emotional intensity (LPC/LPP). However, differences in task setup had an important impact on the variation of ERP outcomes. Systematization of protocols and tasks is indispensable for future studies.

Effectiveness of transcutaneous electrical nerve stimulation improves pain intensity, disability and quality of life in patients with fibromyalgia syndrome: a systematic review with meta-analysis

PURPOSE

The transcutaneous electrical nerve stimulation (TENS) is one of the most frequently electrophysical agents employed in reducing the impact of FMS. This meta-analysis intended to determine the effectiveness of TENS on pain, disability, and quality of life (QoL) in patients with FMS.

METHODS

According to PRISMA, we performed a meta-analysis (CRD42023456439), searching in PubMed Medline, PEDro, CINAHL Complete, Web of Science, and Scopus, since inception up to October 2023. This review focused on controlled clinical trials evaluating the effect of TENS on pain, disability, and QoL in patients with FMS. The pooled effect was estimated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95%CI).

RESULTS

Twelve studies, providing data from 944 patients, were included (PEDro score of 5.6 points). Meta-analyses showed that TENS interventions are effective in improving pain (SMD = -0.61; 95%CI -1 to -0.16); disability (SMD = -0.27; 95%CI -0.41 to -0.12); and physical dimension of QoL (SMD = 0.26; 95%CI 0.08 to 0.44). Additionally, when TENS is used as a unique therapy, it represents the best therapeutic option for improving pain, disability, and QoL.

CONCLUSIONS

This meta-analysis, including the largest number of studies, showed that TENS intervention is an effective therapy to reduce pain and disability and increase QoL in FMS patients.

Suicidal ideation in female individuals with fibromyalgia and comorbid obesity: prevalence and association with clinical, pain-related, and psychological factors

OBJECTIVE

Individuals with fibromyalgia report alarming levels of suicidal ideation, and comorbidity with other chronic health conditions such as obesity-a risk factor for suicidal ideation per se-could further complicate the clinical picture. The aim of this study is to determine, in a sample of women with fibromyalgia and comorbid obesity, the prevalence of suicidal ideation and to evaluate clinical, pain-related and psychological factors associated with suicidal ideation.

METHODS

In total, 156 female individuals with fibromyalgia and obesity were recruited and completed a series of self-report measures that assessed (i) the level of pain intensity, (ii) depressive symptomatology, (iii) sleep quality, and (iv) pain catastrophizing. Suicidal ideation was evaluated by item #9 of the Beck Depression Inventory. In addition, information regarding previous suicide attempts and current opioid use was collected.

RESULTS

3n sum, 7.8% of participants reported presence of suicidal ideation. According to the results of the multiple logistic regression, depressive symptomatology, sleep quality, and pain catastrophizing were associated with the presence of suicidal ideation.

DISCUSSION

The presence of suicidal ideation in our sample was significantly associated with depressive symptomatology, sleep quality, and pain catastrophizing. Our findings are the first to suggest a unique (ie, independent of depressive symptomatology, and sleep quality) association between pain catastrophizing and suicidal ideation in the context of fibromyalgia and comorbid obesity. In order to prevent and reduce suicidal ideation, these factors should be assessed and targeted in interventions for pain management. Future research should investigate the extent to which addressing depressive symptoms, sleep quality, and pain catastrophizing reduces suicidal ideation.

The effect of eye movement desensitization and reprocessing on fibromyalgia: A multiple-baseline experimental case study across ten participants

Fibromyalgia (FM) is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, and stiffness in muscles and joints. Traumatic life experiences and post-traumatic stress symptoms play a role in its development and persistence. Although previous research suggests that pain and FM symptoms decrease after eye movement desensitization and reprocessing (EMDR) therapy, its effectiveness has not been investigated in a controlled manner. The present study investigated the effectiveness of a six-session, 90-minute EMDR therapy using a multiple baseline single-case experimental design (SCED) across ten adult females with FM. The SCED involved a baseline, intervention, one- and three-month follow-up phase. The primary outcome was pain. Secondary outcomes included post-traumatic stress symptoms, other FM symptoms (fatigue, stiffness in muscles and joints), and the impact of FM on daily activities and sleep. Data were statistically analyzed by primarily testing means across phases on an individual and group level. Post-traumatic stress symptoms improved significantly in seven participants. Pain severity decreased significantly in six participants, with three of them maintaining significant improvement three months later. One participant showed clinically relevant change one month later. Furthermore, improvements were observed in secondary outcome measures. The findings support the efficacy of EMDR in reducing FM symptoms.

Lived Experiences of Cognitive Dysfunction in Fibromyalgia: How Patients Discuss Their Experiences and Suggestions for Patient Education

Cognitive dysfunction (CD) is a common, impairing symptom experienced by persons with fibromyalgia (FM). This study explored how individuals with FM describe their experience of CD in an online peer support environment. Posts referencing cognitive symptoms were extracted from two Facebook FM peer support groups at two timepoints. Using inductive Thematic Analysis, key discussion themes were identified and compared across groups and time. Four themes represented the way members described their cognitive experiences in FM: understanding and describing CD experiences, distrust of cognitive abilities, choosing between pain and medication side effects, and misunderstanding and judgement from others. Two themes represented the impact of CD on members' lives: impaired social interaction and loss of identity. Group members described broad impairments in daily functioning that significantly and negatively impacted their quality of life, indicating CD symptoms may play a more prominent role in the FM experience than previously understood. An infographic is included to aid patient education and help facilitate patient-provider discussions of CD symptoms.

Unraveling the Complex Web of Fibromyalgia: A Narrative Review

Fibromyalgia is a complex and often misunderstood chronic pain disorder. It is characterized by widespread musculoskeletal pain, fatigue, and heightened sensitivity, and has evolved in diagnostic criteria and understanding over the years. Initially met with skepticism, fibromyalgia is now recognized as a global health concern affecting millions of people, with a prevalence transcending demographic boundaries. The clinical features and diagnosis of fibromyalgia encompass a range of symptoms beyond pain, including sleep disturbances and cognitive difficulties. This study emphasizes the importance of a comprehensive evaluation for accurate diagnosis, considering the shift from tender point reliance to a more holistic approach. Etiology and pathophysiology involve genetic predisposition, neurotransmitter dysregulation, central sensitization, and immune system involvement. Risk factors such as gender, age, family history, and comorbid conditions contribute to susceptibility. The impact on quality of life is profound, affecting physical and social aspects, often accompanied by mood disorders. Management approaches include pharmacological interventions, non-pharmacological therapies, lifestyle modifications, and alternative treatments. This study also delves into emerging research, exploring advances in neurobiological understanding, brain imaging, genetic markers, glutamate modulation, cannabinoids, gut microbiome, and digital health tools for fibromyalgia management. Overall, this study provides a nuanced and up-to-date overview of the complexities surrounding fibromyalgia, aiming to enhance understanding and support for individuals grappling with this challenging condition.

Effects of Nature-Based Multisensory Stimulation on Pain Mechanisms in Women with Fibromyalgia Syndrome: A Randomized Double-Blind Placebo-Controlled Trial

BACKGROUND

The term "nature-based sensory stimuli" refers to the sensory information produced by biotic and abiotic agents from natural environments. The literature has reported the beneficial effects of these agents on various pain dimensions in non-clinical populations.

AIMS

To evaluate the potential analgesic effects of nature-based multisensory stimulation in women with fibromyalgia syndrome.

METHODS

A randomized, double-blind, placebo-controlled, parallel-group trial with a 1:1 allocation ratio was conducted. Forty-two women with fibromyalgia syndrome interacted with either different plant species with flowers, stones, and soil organic matter or their synthetic imitations for 30 minutes. Outcome measurements were performed before and after the intervention, including clinical pain intensity using the Numeric Rating Scale, cold pain thresholds using the Cold Pressor Test, mechanical hyperalgesia and wind-up using a monofilament, and pressure pain thresholds using a pressure algometer.

RESULTS

Analyses revealed group × time interactions for clinical pain intensity (F = 7.915, p = .008), cold-water immersion time (F = 7.271, p = .010), mechanical hyperalgesia (F = 4.701, p = .036), and pressure pain threshold (p ≤ .017). Between-group differences were found in clinical pain intensity (p = .012), cold pain thresholds (p = .002), and pressure pain thresholds (p < .05). The experimental group exhibited reduced clinical pain intensity (p = .001) and increased pressure pain thresholds (p ≤ .034).

CONCLUSIONS

Women with fibromyalgia syndrome may benefit from multisensory stimulation using biotic and abiotic agents from natural environments for 30 minutes. Interacting with flowering plants and soil components appears to induce analgesic effects.

Neuroticism, perceived stress, adverse life events and self-efficacy as predictors of the development of functional somatic disorders: longitudinal population-based study (DanFunD)

BACKGROUND

Functional somatic disorder (FSD) is a unifying diagnosis that includes functional somatic syndromes such as irritable bowel, chronic widespread pain (CWP) and chronic fatigue. Several psychological factors are associated with FSD. However, longitudinal population-based studies elucidating the causal relationship are scarce.

AIMS

To explore if neuroticism, perceived stress, adverse life events (ALEs) and self-efficacy can predict the development of FSD over a 5-year period.

METHOD

A total of 4288 individuals who participated in the DanFunD baseline and 5-year follow-up investigations were included. FSD was established at both baseline and follow-up, with symptom questionnaires and diagnostic interviews. Neuroticism was measured with the short-form NEO Personality Inventory, perceived stress with the Cohen's Perceived Stress Scale, ALEs with the Danish version of the Cumulative Lifetime Adversity Measure and self-efficacy with the General Self-Efficacy Scale. Associations were investigated with multiple logistic regression models.

RESULTS

Perceived stress predicted incident FSD, irritable bowel, CWP and chronic fatigue (odds ratios: 1.04-1.17). Neuroticism predicted incident FSD and chronic fatigue (odds ratios: 1.03-1.16). ALEs predicted incident FSD, CWP and chronic fatigue (odds ratios: 1.06-1.18). An increase in perceived stress from baseline to follow-up was associated with incident FSD, irritable bowel, CWP and chronic fatigue (odds ratios: 1.05-1.22). Contrary, an increase in self-efficacy seemed to be a protective factor (odds ratios: 0.89-0.99).

CONCLUSIONS

High neuroticism, high perceived stress and a high number of ALEs are risk factors for the development of FSD. Particularly perceived stress seems to be an important contributor to the onset of FSD.

A retrospective analysis of the prevalence and impact of associated comorbidities on fibromyalgia outcomes in a tertiary care center

Background

This retrospective study was designed to analyze the prevalence and impact of associated comorbidities on fibromyalgia (FM) outcomes (functionality, pain, depression levels) for patients who participated in an intensive multicomponent clinical program in a tertiary care center.

Methods

Participants included a sample of 411 patients diagnosed with FM at a large tertiary medical center using the 2016 ACR criteria. Patients completed an intensive 2-day cognitive behavioral treatment (CBT) program, filled out the Fibromyalgia Impact Questionnaire Revised (FIQR), the Center for Epidemiologic Studies Depression Scale (CES-D), the Pain Catastrophizing Scale (PCS), and were followed for 6 months after treatment completion. T-tests were performed to analyze differences between the presence or absence of select comorbidities for the three outcomes at follow-up. Statistically significant comorbidities (p < 0.05) were used as predictors in multivariable logistic regression models.

Results

The FM associated comorbidities in this cohort that had significant impact on the measured outcome domains after treatment program completed were Obesity (FIQR p = 0.024), Hypothyroidism (CES-D p = 0.023, PCS p = 0.035), Gastroesophageal reflux disease GERD (PCS p < 0.001), Osteoarthritis (CES-D p = 0.047). Interestingly, Headache, the most frequent FM associated comorbidity in this cohort (33.6%), did not have a significant impact on the outcome domains at follow-up. Obesity (18.2%) was the only FM associated comorbidity significantly impacting all three outcome domains at follow-up.

Conclusion

The present study suggests that addressing obesity may significantly impact outcomes in FM patients.

Clinical relevance of resistance training in women with fibromyalgia: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

There has been an increase in the number of papers assessing the effects of resistance training (RT) in patients with fibromyalgia. Therefore, the objective of our study was to evaluate the clinical relevance and effectiveness of RT for pain intensity, functionality and severity of the disease specifically in women with fibromyalgia through a systematic review with meta-analysis.

DATABASES AND DATA TREATMENT

Seven databases were searched. Randomized controlled trials conducted in women over 18 years of age with fibromyalgia were included. Fifteen trials were included in the systematic review and 14 of these studies were included in the three meta-analyses performed. Study quality assessment was performed using the PEDro scale. In addition, the GRADE recommendations were used.

RESULTS

The global meta-analysis revealed statistically significant differences in the RT group versus the control group on pain intensity (SMD = -0.49; 95% CI [-0.74, -0.24], p = 0.0001), functionality (SMD = -0.23; 95% CI [0.01, 0.45], p = 0.04) and on severity of the disease (SMD = -0.58; 95% CI [-0.90, -0.26], p = 0.0005). Clinically relevant improvements in the overall outcome of the three variables studied in favour of RT were obtained.

CONCLUSIONS

RT is effective to improve pain intensity, functionality and severity of the disease in women with fibromyalgia. These improvements are clinically relevant. More clinical trials of RT are needed in women with fibromyalgia to support our results due to the low strength of evidence.

SIGNIFICANCE

This systematic review with meta-analysis provides evidence that RT produces clinically relevant improvements in women with fibromyalgia. The absence of immediate benefit is often a major barrier to adherence to treatment. Our findings will help clinicians to empower patients that if they continue treatment, they will achieve improvement in their disease.

Implication of intestinal microbiota in the etiopathogenesis of fibromyalgia: A systematic review

Fibromyalgia (FM) is a highly prevalent chronic disease. About 4.7% of the world's population suffers from generalized pain and hypersensitivity, in addition to a wide range of physical and psychological symptoms. The etiopathogenesis of this disease is multifactorial, which makes its diagnosis and treatment challenging. Recently, the increase in the number of studies on microbiota has provided new data that can help to understand the onset and development of FM. An updated systematic review of the causes of FM has been carried out in this work. Particularly in the last decade, research has focused on the gut-brain axis, which has emerged as a crucial mechanism for microbiota-host crosstalk. In FM patients, quantitative imbalances of the intestinal microbiota (dysbiosis) and bacterial metabolites with differential relative abundance have been found, especially short-chain fatty acids and lipopolysaccharides. Furthermore, the microbiota has been found to indirectly influence host neurotransmitter mechanisms, mainly through the serotonin precursor, glutamate, and gamma-aminobutyric acid. Thus, all these mechanisms and their influence on the etiopathogenesis of FM are discussed in this review.

Fibromyalgia Animal Models Using Intermittent Cold and Psychological Stress

Fibromyalgia (FM) is a chronic pain condition characterized by widespread musculoskeletal pain and other frequent symptoms such as fatigue, sleep disturbance, cognitive impairment, and mood disorder. Based on the view that intermittent stress would be the most probable etiology for FM, intermittent cold- and intermittent psychological stress-induced generalized pain (ICGP and IPGP) models in mice have been developed and validated as FM-like pain models in terms of the patho-physiological and pharmacotherapeutic features that are shared with clinical versions. Both models show long-lasting and generalized pain and female-predominant sex differences after gonadectomy. Like many other neuropathic pain models, ICGP and IPGP were abolished in lysophosphatidic acid receptor 1 (LPAR1) knock-out mice or by LPAR1 antagonist treatments, although deciding the clinical importance of this mechanism depends on waiting for the development of a clinically available LPAR1 antagonist. On the other hand, the nonsteroidal anti-inflammatory drug diclofenac with morphine did not suppress hyperalgesia in these models, and this is consistent with the clinical findings. Pharmacological studies suggest that the lack of morphine analgesia is associated with opioid tolerance upon the stress-induced release of endorphins and subsequent counterbalance through anti-opioid NMDA receptor mechanisms. Regarding pharmacotherapy, hyperalgesia in both models was suppressed by pregabalin and duloxetine, which have been approved for FM treatment in clinic. Notably, repeated treatments with mirtazapine, an α2 adrenergic receptor antagonist-type antidepressant, and donepezil, a drug for treating Alzheimer's disease, showed potent therapeutic actions in these models. However, the pharmacotherapeutic treatment should be carried out 3 months after stress, which is stated in the FM guideline, and many preclinical studies, such as those analyzing molecular and cellular mechanisms, as well as additional evidence using different animal models, are required. Thus, the ICGP and IPGP models have the potential to help discover and characterize new therapeutic medicines that might be used for the radical treatment of FM, although there are several limitations to be overcome.

The lived experiences of oropharyngeal dysphagia in adults living with fibromyalgia

BACKGROUND

Fibromyalgia is a chronic pain condition which has recently been linked with eating, drinking and swallowing difficulties (dysphagia). However, to date, sample sizes within completed research are small and study designs heterogeneous, and therefore, little is known about the lived experiences of dysphagia among people with fibromyalgia. To go some way towards addressing this gap in the literature, this study collected and analysed the first-hand experiences of the physical symptoms, the psychosocial impacts and environmental factors that influenced the lived experience of a sample of people living with fibromyalgia-associated dysphagia.

METHODS

Qualitative semi-structured interviews were conducted with adults with dysphagia and fibromyalgia. Reflexive thematic analysis was employed and themes were identified regarding the reported experience and impact of swallowing problems. The same researcher conducted the interviews and extracted all data, and a second researcher analysed a random sample of 5% of the data for accuracy, with no disagreements arising between the two researchers.

RESULTS

All participants (n = 8) reported the negative psychosocial impact of their dysphagia. Participants reported managing their dysphagia independently, primarily using compensatory strategies. Participants discussed feeling unsupported in healthcare interactions due to clinicians not understanding the occurrence, nature or impact of eating, drinking and swallowing difficulties. Participants also reported that they did not have access to evidence-based management strategies that adequately addressed their fibromyalgia-related swallowing problems.

CONCLUSIONS

Despite minimal previous research in this area, findings here highlight the impact that dysphagia has on people with fibromyalgia. A broad range of physical symptoms were reported to have negative consequences across both social and emotional domains. The reported symptoms often required complex coping strategies and sometimes impeded participants from seeking suitable medical intervention from healthcare providers. There are both broad-ranging implications of fibromyalgia-associated dysphagia and reported poor perceptions of medical interactions for this cohort of patients. Therefore, there is evidently a need for clinical research into the management of this condition to develop patient-centred care delivery options and to equip healthcare professionals with the knowledge and skills necessary to provide efficacious management to this group.

PATIENT OR PUBLIC CONTRIBUTION

Before initiation of the qualitative interviews, the interview schedule was piloted with an individual living with fibromyalgia and dysphagia, with feedback provided on the appropriate wording and format of semi-structured questioning.

"It's very saddening, you keep on wondering when the symptoms will be over": A qualitative study exploring the long-term chikungunya disease impact on daily life and well-being, 6 years after disease onset

BACKGROUND

Long-term chikungunya is a mosquito-borne disease, characterized by disabling rheumatic symptoms persisting for years, after infection with the chikungunya virus. Previous studies focused on assessing the well-being of affected individuals from a quantitative perspective using generic instruments, and have reported physical and psychological impairment. However, a common critique is that generic instrument's structured responses and pre-defined health domains selected by health professionals, may not capture the full extent of well-being impairment experienced by patients. This study aimed to explore in-depth to which extent long-term chikungunya disease impacts daily living and the physical, psychological, and social well-being from the experiences and perspective of affected individuals.

METHODOLOGY/PRINCIPAL FINDINGS

Using open-ended questions, in-depth interviews were conducted with 20 purposively selected individuals with long-term chikungunya disease, in Curaçao. Interview audio-recordings were transcribed verbatim. The data were thematically analyzed. Living with persistent rheumatic symptoms affected the participant's daily living and well-being in several ways: experience of physical impact (restricted physical functioning and limitations in activities of daily life); experience of psychological impact (altered emotional state, fear of walking and running, psychosocial aspects of footwear adaptations, and uncertainty about disease progression and future health); and experience of social impact (social isolation and impaired relational maintenance, social dependency, challenges of social support, at-work productivity loss, and giving up leisure activities after work).

CONCLUSIONS/SIGNIFICANCE

This study, the first of its kind, indicated that the adverse impact of long-term chikungunya disease is currently underreported. The persistent rheumatic symptoms had a negative effect on functional ability, which in turn impacted broad aspects of daily life and well-being, beyond what is captured by generic instruments. In the view of the findings, physical exercise programs including manual therapy, aerobics, resistance and stretching exercises, and orthopaedic footwear interventions in a multidisciplinary patient-centred approach may improve physical function and subsequently overall well-being.

Chronic pain trials often exclude people with comorbid depressive symptoms: A secondary analysis of 346 randomized controlled trials

BACKGROUND

Chronic pain and depression are common comorbid conditions, but there is limited evidence-based guidance for management of the two conditions together. In recent years, there has been an increase in the number of chronic pain randomized controlled trials that collect depression outcomes, but it is unknown how often these trials include people with depression or significant depressive symptoms. If trials do not include participants representative of real-world populations, evidence and guidance generated from these trials risk being inapplicable for large proportions of the target population, or worse, risk harm. Thus, in order to identify pathways to improve the conduct of clinical trials, the aims of this study were to (1) estimate the proportion of randomized controlled trials evaluating chronic pain interventions and reporting depression outcomes that include participants with significant depressive symptoms; and (2) assess the variability of inclusion proportions by pain type, intervention type, gender, country of origin, and publication year.

METHODS

Studies were extracted from an umbrella review of interventions for chronic pain that reported depression outcomes. Screening and data extraction were completed in duplicate and conflicts were resolved by a third author. Randomized controlled trials with at least 50% adult participants and validated depression scales were included, and randomized controlled trials with populations whose mean scores were at or above depression thresholds at baseline were considered to have included participants with depression.

RESULTS

Of the 346 randomized controlled trials analyzed, 142 (41%) included participants with depression. Eight pain-type groups and nine intervention types were identified. Randomized controlled trials investigating fibromyalgia and mixed chronic pain had the highest proportion of participants with depression, whereas studies of arthritis and axial pain had among the lowest. Randomized controlled trials from the United States had a significantly lower inclusion proportion compared with non-US studies, especially for studies on arthritis. The increase in inclusion proportion by publication year was driven by the increase in fibromyalgia studies.

DISCUSSION AND CONCLUSION

This study highlights opportunities to improve the conduct of chronic pain clinical trials. The majority of randomized controlled trials s analyzed evaluated participants without significant depressive symptoms at baseline, thus the findings synthesized in systematic reviews and subsequent guidelines are most applicable to the subset of real-world populations that do not have significant depressive symptoms. As well, systemic biases around psychological conditions and gender may be important contributors to differences in the study of depression in fibromyalgia compared with common conditions such as arthritis and axial pain. In order to better inform clinical practice, future research must intentionally include individuals with comorbid depression in trials of common chronic pain conditions, and consider methods to mitigate biases that may distort study design.

"Don't need [therapy]! Not necessary, that's what we're for!": Does content from fibromyalgia Facebook peer support groups emulate psychological flexibility principles?

Objective

Many persons with fibromyalgia (FM) use online peer support groups (OPSGs) to address unmet emotional or psychological needs. Some OPSG members have suggested that participation in an OPSG is a viable substitute for professional psychological services, however, no published research exploring this claim was identified.

Methods

Discussion content collected from three Facebook FM OPSGs was thematically analyzed to explore whether the content posted in FM OPSGs emulated content consistent with the psychological flexibility model underlying Acceptance and Commitment Therapy (ACT) - an evidence-based psychotherapy for chronic pain conditions.

Results

The content posted in OPSGs did not emulate and often contradicted the core psychological flexibility processes or skills emphasized in ACT programs.

Conclusion

Participation in an FM OPSG should be approached cautiously. Content from the FM OPSGs should not be considered a substitute for professionally delivered ACT, although participation may provide emotional support to help individuals move towards readiness for active psychotherapy.

Innovation

This research represents a novel application of the psychological flexibility model underlying ACT to assess the potential therapeutic value of a peer support community. Additionally, it is the first to clarify that content in FM OPSGs is not aligned with psychological flexibility processes.

Elevated high sensitive C-reactive protein in fibromyalgia

Introduction

Fibromyalgia syndrome (FMS) is a complex chronic pain condition characterized by widespread pain and tenderness, fatigue, and sleep disturbances. Currently, factors contributing to FMS are considered to be multifactorial, and the involvement of inflammatory processes is a question of debate.

Objective

The aims of this study were (1) to assess whether serum concentrations of high-sensitivity C-reactive protein (hsCRP) differ between individuals diagnosed with FMS and pain-free controls, (2) to determine whether these differences are associated with clinical symptoms, and (3) to explore whether the observed differences can be explained by specific covariates such as age, weight, and smoking status.

Methods

An ANOVA was applied to identify differences of hsCRP levels between FMS and pain-free controls and an analysis of covariance (ANCOVA) was performed to investigate the dependencies of hsCRP with respect to covariates. To assess the reliability of our findings, we also utilized a Bayesian robust estimation model to determine the level of confidence associated with our results.

Results

The results showed that individuals with FMS had higher hsCRP levels compared to healthy controls [F(1,106) = 8.802, p < 0.001] and that higher hsCRP levels were significant correlated with a higher symptom burden (r = 0. 287, p = 0.008) and more tender points (r = 0.307, p = 0.005). Further, hsCRP levels were significantly associated with weight (η2 = 0.154, p < 0.001), but independent of age (η2 = 0.005, p = 0.42), smoking status (η2 = 0.002, p = 0.623), or gender (η2 = 0.0045, p = 0.437), which resulted in an insignificant group effect between FMS and controls (η2 = 0.029, p = 0.052), even after controlling for covariates.

Conclusion

In conclusion, this study provides evidence that sub-inflammatory processes correlate with clinical symptoms, which can be partly attributed to differences in weight, but cannot be fully explained by them. Further research is needed to elucidate the mechanisms underlying the association between hsCRP and FMS and to explore the potential therapeutic implications of targeting hsCRP in the management of FMS.

Personality Disorders and Traits of ABC Clusters in Fibromyalgia in a Neurological Setting

BACKGROUND

Evidence suggests that there is substantial comorbidity between fibromyalgia and Axis II pathology (i.e., personality disorders-PDs). The aim of the current study was to find out the exact cluster (A, B, C) of PDs or traits that are more prominent in FM and may be predictors of FM diagnosis.

METHODS

Data from 86 subjects (53 with FM and 33 controls without FM) were analyzed in an observational, cross-sectional, comparative study in a neurological setting. The assessment of categorical PDs and traits was performed independently with the Structured Clinical Interview for Personality Disorders (SCID-II). Binary logistic regression was used to determine FM predictors among PD traits.

RESULTS

Compared with controls, FM patients had a higher rate of PD diagnoses (56.7 vs. 18.2%, p < 0.001). However, the rate was significantly higher only for borderline PD diagnosis (28.3% vs. 6.1% p < 0.05). The binary logistic regression analysis showed that schizotypal and schizoid (cluster A), borderline (cluster B), and dependent (cluster C) personality traits may be significant predictors of fibromyalgia (Nagelkerke R2 = 0.415).

CONCLUSIONS

Our results may reflect the association of FM with personality traits of all three PD clusters: A (eccentric), B (dramatic), and C (anxious). However, the most consistent evidence seems to be for borderline PD.

The impact of rumination on fibromyalgia pain after physical activity: an experimental study

Some fibromyalgia (FM) patients engage in rumination (i.e. a chain of repetitive, passive and relatively uncontrollable thoughts focused on negative content) to cope with the pain and discomfort of daily activities. The partial model of rumination in chronic pain suggests that rumination processes may play a causal role in maintaining pain. Rumination might also be one of the key factors interfering with the reestablishment of adapted physical activity. The objective of this study was to test how rumination vs. distraction induction influence FM patients' pain intensity, discomfort linked to pain, and affect after physical activity. Forty-seven participants with a diagnosis of FM were randomly assigned to undergo distraction induction vs. rumination induction after performing a physical activity in ecological setting. Their pain intensity, pain-related discomfort, and affect were measured at the baseline, after physical activity, and after rumination versus distraction induction. A series of mixed-design ANOVAs showed that rumination induction after physical activity impairs patients' recovery in terms of pain intensity and discomfort, but not affect, as compared to the distraction condition. In conclusion, participants with fibromyalgia who engage in rumination following a physical activity recover less from their pain experience as compared to distraction induction. These results are consistent with the partial model of rumination in chronic pain and support the idea that rumination may play a causal role in the development and maintenance of pain.

Assessment of the therapeutic potential of lutein and beta-carotene nanodispersions in a rat model of fibromyalgia

Fibromyalgia (FM) is a chronic disorder characterized by widespread musculoskeletal pain, fatigue, and cognitive impairment. Despite the availability of various treatment options, FM remains a challenging condition to manage. In the present study, we investigated the efficacy of formulated nanodispersions of lutein and beta-carotene in treating FM-related symptoms induced by reserpine in female Wistar rats. Several techniques have been implemented to assess this efficacy at various levels, including biochemical, bioelectrical, and behavioral. Namely, oxidative stress markers, monoamine levels, electrocorticography, pain threshold test, and open field test were conducted on control, FM-induced, and FM-treated groups of animals. Our results provided compelling evidence for the efficacy of carotenoid nanodispersions in treating FM-related symptoms. Specifically, we found that the dual action of the nanodispersion, as both antioxidant and antidepressant, accounted for their beneficial effects in treating FM. With further investigation, nano-carotenoids and particularly nano-lutein could potentially become an effective alternative treatment for patients with FM who do not respond to current treatment options.

Influence of socio-affective factors on quality of life in women diagnosed with fibromyalgia

Introduction

Fibromyalgia is a disease that involves chronic pain, with high prevalence in the female population and great impact on the bio-psycho-social sphere of people affected by it. However, few studies have analyzed the possible influence of socio-affective factors on the quality of life of people who suffer from this disease.

Objective

The aim of this study was to determine the relationships between the impact of this disease on the lives of people with fibromyalgia and these variables. Specifically, we analyzed the quality of partner relationship, perceived loneliness, life satisfaction, and perceived socio-family situation.

Method

A descriptive-correlational cross-sectional design was used. The sample consisted of 69 women diagnosed with fibromyalgia. The participants completed different questionnaires that measured their happiness, satisfaction with life, perceived loneliness, quality of partner relationship, socio-family valuation, and the impact of fibromyalgia.

Results

The quality of partner relationship, perceived loneliness and socio-family valuation seem to be good predictors of subjective happiness, life satisfaction, and the impact that fibromyalgia has on people's lives, in the sense that the more positive the valuation of the couple relationship and of the socio-family situation, and the lower the perceived loneliness, people feel happier, more satisfied with their lives and the lower the impact that fibromyalgia has on their lives.

Conclusion

The 50% of satisfaction with life can be explained from the scores obtained in perceived loneliness and the quality of partner relationship. In this sense, perceived loneliness was a good predictor of the impact of fibromyalgia on the lives of these patients.

Body reprogramming for fibromyalgia and central sensitivity syndrome: A preliminary evaluation

Objectives

Central sensitivity syndrome disorders such as fibromyalgia, provoke continued debate, highlighting diagnostic and therapeutic uncertainty. The Hyland model provides a way of understanding and treating the medically unexplained symptoms of central sensitivity syndromes using complexity theory and principles of adaption in network systems. The body reprogramming is a multi-modal intervention based on the Hyland model designed for patients living with medically unexplained symptoms. This preliminary, naturalistic and single-arm service evaluation set out to evaluate outcome after attending a body reprogramming course in patients living with fibromyalgia or central sensitivity syndrome.

Methods

Patients diagnosed with fibromyalgia or central sensitivity syndrome were recruited. The body reprogramming courses consisting of eight sessions, each 2.5 h in length, were run at two study sites in England. Data were collected at baseline, post course and 3-months post course using questionnaires assessing symptomatology (FIQR/SIQR), Depression (PHQ9), Anxiety (GAD7) and quality of life (GQoL). Repeated measures t-tests were used, and all comparisons were conducted on an intention to treat basis.

Results

In total, 198 patients with a mean age of 47.73 years were enrolled on the body reprogramming courses. Statistically and clinically significant improvement were observed in the FIQR from baseline to post course (mean change: 11.28) and baseline to follow-up (mean change: 15.09). PHQ9 scores also improved significantly from baseline to post course (mean reduction 3.72) and baseline to follow-up (mean reduction 5.59).

Conclusions

Our study provides first evidence that the body reprogramming intervention is an effective approach for patients living with fibromyalgia or central sensitivity syndromes on a variety of clinical measures. Besides these promising results, important limitations of the study are discussed, and larger randomized controlled trials are clearly warranted.

Fibromyalgia syndrome is associated with sexual dysfunction regardless of physical activity status: a cross-sectional study

BACKGROUND

Fibromyalgia syndrome (FMS) is a rheumatic disorder that has been observed to affect self-perception of sexuality.

AIM

The study aims to assess sexual dysfunction (SD), establish possible associations with SD levels, and evaluate the impact of physical activity (PA) levels on SD in Spanish women with FMS as compared with healthy control women.

METHODS

The study was cross-sectional. A total of 170 women voluntarily agreed to participate between September 2019 and February 2020: 88 in the FMS group and 82 in the control group.

OUTCOMES

The main outcome measures were SD, as assessed through the Female Sexual Function Index (FSFI), and PA levels, as assessed with a structured interview.

RESULTS

There were significant differences in every domain and total SD score between the FMS and control groups (P < .05). In addition, we obtained a moderate significant direct association (χ2[1] = 37.071, P < .05, phi = 0.467) when exploring the associations between FMS and risk of SD. Results showed statistically significant differences between the FMS group and the control group when PA levels were not reached in the desire, pain, and total scores of the FSFI (P < .05). When the PA levels were reached, between-group differences were found in all domains, as well as in the total score of the FSFI (P < .05).

CLINICAL IMPLICATIONS

Sexual function should be evaluated in women with FMS, while future treatments should address this clinical area with the aim of managing SD in this population.

STRENGTHS AND LIMITATIONS

The main limitation is that the outcome measures were self-reported.

CONCLUSION

We found a high prevalence of SD in Spanish women with FMS, with an impact on aspects such as desire, arousal, lubrication, orgasm, satisfaction, and pain during sexual intercourse. In addition, there is a moderate direct association between FMS and SD. Ultimately, the results showed that, irrespective of PA, women with FMS reported increased SD.

Efficacy of cupping therapy in individuals with fibromyalgia. A systematic review of randomized clinical trials

BACKGROUND

Fibromyalgia is a chronic and idiopathic condition and is among the most common causes of generalized chronic pain, even affecting psychological and cognitive aspects.

AIM

To evaluate the efficacy of cupping therapy on pain, quality of life, sleep disorders, and the impact of the disease in subjects with fibromyalgia.

METHODS

We searched the Pubmed, CINAHL, Epistemonikos, Scopus, and Web of Science databases. Randomized controlled trials involving adults with fibromyalgia undergoing cupping were included. Pain intensity, quality of life, sleep disturbances, and the impact of fibromyalgia were assessed. We have reported the results using descriptive statistics and narrative synthesis.

RESULTS

Two articles with a total of 155 participants were included. Large effect sizes were found for pain intensity, moderate for quality of life, and low for the impact of fibromyalgia and sleep disorders. However, the certainty of the evidence is low for most outcomes except for sleep disorders.

CONCLUSIONS

There is a discrepancy in the efficacy of cupping therapy in improving pain intensity, quality of life, sleep disturbances, and disease impact in people with fibromyalgia. Future high-quality randomized clinical trials are required.

Patient and primary care practitioners' perspectives on consultations for fibromyalgia: a qualitative evidence synthesis

BACKGROUND

Fibromyalgia presents a challenge to both the patients experiencing symptoms and the staff aiming to treat them. This qualitative review aimed to synthesise how patients and practitioners experience primary care consultations, develop a rounded picture of how they perceive each other, the challenges to primary care consultation and how they might be tackled.

METHODS

CINAHL, Embase, CENTRAL and Medline were searched from inception to November 2021. Qualitative studies were included if they explored the perspectives and experiences of either fibromyalgia patients or primary care practitioners. Quantitative data, studies not published in English, not set in primary care or that did not distinguish the type of patient or clinician were excluded. Included studies were analysed using thematic synthesis and their quality assessed.

RESULTS

In total, 30 studies met the inclusion criteria. Thematic synthesis identified three overarching themes: (1) life turned upside down - exploring the chaos experienced by patients as they seek help; (2) negative cycle - highlighting how patient and practitioner factors can create a detrimental cycle; and (3) breaking the cycle - validating patient-doctor relationships underpinned by clear communication can help break the negative cycle.

CONCLUSIONS

Fibromyalgia patients experience uncertainty and chaos that can clash with the attitudes of GPs and the help they can feasibly provide. Difficult consultations in which neither the GP nor patient are satisfied can easily occur. Promoting supportive, reciprocal and open patient-doctor relationships is essential. Future research is required to further explore GP attitudes and to develop an intervention that could improve consultations, patient outcomes and GP satisfaction.

Social variables for replication of studies using mean scores of social support, self-care, and fibromyalgia knowledge: a cross-sectional study

To investigate biopsychosocial variables that contribute to explaining social support, self-care, and fibromyalgia knowledge in patients with fibromyalgia. A cross-sectional study. We built ten models of predictive variables (schooling, ethnicity, associated diseases, body regions affected by pain, employment status, monthly income, marital status, health level, medication, sports activities, interpersonal relationships, nutrition level, widespread pain, symptom severity, cohabitation, dependent people, number of children, social support, self-care, and fibromyalgia knowledge) and individually tested their explanatory performance to predict mean scores on the Fibromyalgia Knowledge Questionnaire (FKQ), Medical Outcomes Study's Social Support Scale (MOS-SSS), and Appraisal of Self-Care Agency Scale-Revised (ASAS-R). We used analysis of variance to verify the association among all variables of mathematically adjusted models (F-value ≥ 2.20) and we reported only models corrected with p < 0.05 and R2 > 0.20. One hundred and ninety people with fibromyalgia (aged 42.3 ± 9.7 years) participated in the study. Our results show that the variables schooling, ethnicity, body regions affected by pain, frequency of sports activities, dependent people, number of children, widespread pain, social support, and self-care determine 27% of the mean FKQ scores. Marital status, self-care, and fibromyalgia knowledge determine 22% of mean MOS-SSS scores. Schooling, ethnicity, employment status, frequency of sports activities, nutrition level, cohabitation, number of children, social support, and fibromyalgia knowledge determine 30% of the mean ASAS-R scores. Studies using mean scores of social support, self-care, and fibromyalgia knowledge should collect and analyze the social variables described in the present study.

Evaluation of sexual function and depression in female patients with fibromyalgia

OBJECTIVE

Fibromyalgia is one of the most important problems, especially for women. Studies point to disorders in the sexual functions of fibromyalgia patients that reduce their quality of life. The aim of this study was to investigate sexual dysfunction and its relationship with disease severity and depression in women with fibromyalgia.

METHODS

This study included 98 female patients diagnosed with fibromyalgia and 54 healthy women. The Female Sexual Function Index was used to assess sexual dysfunction. Fibromyalgia disease severity was measured with the Fibromyalgia Impact Questionnaire. Hamilton Depression Scale was filled in to evaluate the depression status of the patients.

RESULTS

According to the female sexual function index data, female sexual dysfunction was found in 78 (79.6%) patients with fibromyalgia and only in 12 (22.2%) controls. When the female sexual function index scores of fibromyalgia patients with and without depression were compared, patients with additional depression had lower female sexual function index scores, and this difference was statistically significant (p=0.002). In the correlation analysis, the female sexual function index score showed a significant negative correlation with the hamilton depression scale (rho=-0.235, p=0.020) and fibromyalgia impact questionnaire (rho=-0.215, p=0.033) scores.

CONCLUSION

This study highlights the high prevalence of sexual dysfunction in female fibromyalgia patients and the significant correlation between sexual dysfunction and both disease severity and depression.

Stress biomarkers in individuals with fibromyalgia syndrome: a systematic review with meta-analysis

ABSTRACT

Evidence suggests an involvement of hypothalamic-pituitary-adrenal (HPA) axis dysregulation in the development and maintenance of fibromyalgia syndrome (FMS). However, studies on the stress response via the HPA-axis in individuals with FMS show conflicting results. To better understand the relationship between FMS and HPA-axis dysregulation, we (1) systematically summarized the current level of evidence on HPA biomarkers in individuals with FMS compared with individuals without and (2) evaluated whether FMS is associated with a specific pattern of HPA dysregulation. The main outcome measures were cortisol, adrenocorticotropic hormone (ACTH), corticotropin-releasing hormone (CRH), epinephrine, and norepinephrine. A systematic search of MEDLINE, EMBASE, and PsychMed yielded 47 studies eligible for meta-analysis, including 1465 individuals with FMS and 1192 FMS-free controls. No main effect of FMS was found on altered levels of blood cortisol, ACTH, CRH, and epinephrine. Compared with controls, salivary and urinary cortisol levels were decreased in individuals with FMS, whereas blood levels of norepinephrine were increased. However, heterogeneity of data was high with significant evidence for publication bias. Overall, the data are compatible with association of FMS with adrenocortical hypofunction in the presence of increased sympathetic tone. However, the data are partially contradictory, so it must be assumed that the data are highly dependent on the respective study designs, patient samples, and analytical methods and do not necessarily demonstrate an abnormal HPA-axis function in FMS.

The association between adverse childhood experiences, self-silencing behaviours and symptoms in women with fibromyalgia

Poor adult health has consistently been associated with Adverse Childhood Experiences (ACEs). The process is not fully understood but is likely to involve a complex interaction of biological and psychosocial factors. Early life stress can affect the developing brain resulting in long-term hyper-responses to stress and raised inflammatory biomarkers. Women with fibromyalgia syndrome (FMS) frequently report ACEs and also self-sacrificial behaviours whereby they repress their own needs and emotions to preserve personal relationships. This behavioural profile (termed self-silencing) may develop following ACEs but has not previously been considered in the context of FMS. This study examined whether self-silencing mediates the link between ACEs and FMS symptoms. Women with (N = 539) and without (N = 184) an FMS diagnosis completed measures of Silencing-the-Self, health symptoms and ACEs. Number of ACEs and symptom levels were significantly associated in both groups. One aspect of self-silencing, care and self-sacrifice (putting others needs before your own) mediated the association between ACEs and symptoms in the FMS group only. Externalised self-perception (judging oneself according to perceived external standards) was negatively associated with symptoms but presented no mediating effects. Results present preliminary new information to explain the association between ACEs and FMS. Recognition of the factors which underlie symptomology is important in understanding the condition and supporting patients.

e-Health Interventions Targeting Pain-Related Psychological Variables in Fibromyalgia: A Systematic Review

There is growing evidence to support the potential benefit of e-Health interventions targeting psychosocial outcomes and/or pain-related psychological variables for chronic pain conditions, including fibromyalgia syndrome (FMS). This systematic review aims at providing an in-depth description of the available e-Health psychological and/or multicomponent interventions for patients with FMS. Searches were made in PubMed, Cochrane, Web of Science, and PsycINFO up to 15 May 2023, finally including twenty-six articles. The quality of the included articles was medium-high (average quality assessment score of 77.1%). 50% of studies were randomized controlled trials (RCTs) (n = 13), and the majority of them focused exclusively on adult patients with FMS (n = 23) who were predominantly female. Four categories of e-Health modalities were identified: web-based (n = 19), mobile application (m-Health) (n = 3), virtual reality (VR) (n = 2), and video consulting (n = 2). Interventions were mainly based on the cognitive behavioral therapy (CBT) approach (n = 14) and mostly involved contact with a healthcare professional through different digital tools. Overall, a growing number of psychological and multicomponent interventions have been created and delivered using digital tools in the context of FMS, showing their potentiality for improving psychosocial outcomes and pain-related psychological variables. However, some digital tools resulted as underrepresented, and the literature on this topic appears highly heterogeneous precluding robust conclusions.

MicroRNA-Related Polymorphism and Their Association with Fibromyalgia

MicroRNAs are tissue-specific expressed short RNAs that serve post-transcriptional gene regulation. A specific microRNA can bind to mRNAs of different genes and thereby suppress their protein production. In the context of the complex phenotype of fibromyalgia, we used the Axiom miRNA Target Site Genotyping Array to search genome-wide for DNA variations in microRNA genes, their regulatory regions, and in the 3'UTR of protein-coding genes. To identify disease-relevant DNA polymorphisms, a cohort of 176 female fibromyalgia patients was studied in comparison to a cohort of 162 healthy women. The association between 48,329 markers and fibromyalgia was investigated using logistic regression adjusted for population stratification. Results show that 29 markers had p-values < 1 × 10^-3, and the strongest association was observed for rs758459 (p-value of 0.0001), located in the Neurogenin 1 gene which is targeted by hsa-miR-130a-3p. Furthermore, variant rs2295963 is predicted to affect binding of hsa-miR-1-3p. Both microRNAs were previously reported to be differentially expressed in fibromyalgia patients. Despite its limited statistical power, this study reports two microRNA-related polymorphisms which may play a functional role in the pathogenesis of fibromyalgia. For a better understanding of the disease pattern, further functional analyses on the biological significance of microRNAs and microRNA-related polymorphisms are required.

The Biology of Chronic Pain and Its Implications for Pain Neuroscience Education: State of the Art

Pain is an individualized experience for the person suffering from chronic pain. Significant strides have been made in the last few decades in understanding various biological changes that coincide with chronic pain. This state-of-the-art overview looks at the current evidence related to the biology of chronic pain and the implications these findings have on the delivery of pain neuroscience education (PNE). The paper summarizes the various (epi)genetic, neural, endocrine, and immune factors discovered and explored in the scientific literature concerning chronic pain. Each of these biological factors has various implications for the content and delivery of PNE. We discuss the future directions these biological factors have for the clinical implementation of PNE by linking the importance of behavior change, optimizing the learning environment, and using an individualized multimodal treatment approach with PNE. In addition, future directions for research of PNE based on these biological factors are provided with importance placed on individualized patient-centered care and how PNE can be used with traditional modes of care and growing trends with other care methods. PNE was originally and continues to be rooted in understanding chronic pain biology and how that understanding can improve patient care and outcomes.

The Analgesic Effect of Transcranial Direct Current Stimulation in Fibromyalgia: A Systematic Review, Meta-Analysis, and Meta-Regression of Potential Influencers of Clinical Effect

BACKGROUND

There is tentative evidence to support the analgesic effect of transcranial direct current stimulation (tDCS) in fibromyalgia (FM), with large variability in the effect size (ES) encountered in different clinical trials. Understanding the source of the variability and exploring how it relates to the clinical results could characterize effective neuromodulation protocols and ultimately guide care in FM pain. The primary objective of this study was to determine the effect of tDCS in FM pain as compared with sham tDCS. The secondary objective was to explore the relationship of methodology, population, and intervention factors and the analgesic effect of tDCS in FM.

MATERIALS AND METHODS

For the primary objective, a systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized clinical trials (RCTs) investigating tDCS as an intervention for FM pain were searched in MEDLINE, Embase, and the Web Of Science. Studies were excluded if they used cross-over designs or if they did not use tDCS as an intervention for pain or did not measure clinical pain. Analysis for the main outcome was performed using a random-effects model. Risk of bias and evidence certainty were assessed for all studies using Cochrane Risk of Bias and Grading of Recommendations Assessment, Development, and Evaluation tools. For the secondary objective, a meta-regression was conducted to explore methodology, population, and intervention factors potentially related to the ES.

RESULTS

Sixteen RCTs were included. Six studies presented a high risk of bias. Significant reduction in pain scores were found for FM (standardized mean difference = 1.22, 95% CI = 0.80-1.65, p < 0.001). Subgroup analysis considering tDCS as a neural target revealed no differences between common neural sites. Meta-regression revealed that the duration of the tDCS protocol in weeks was the only factor associated with the ES, in which protocols that lasted four weeks or longer reported larger ES than shorter protocols.

CONCLUSIONS

Results suggest an analgesic effect of tDCS in FM. tDCS protocols that last four weeks or more may be associated with larger ESs. Definite conclusions are inadequate given the large heterogeneity and limited quality of evidence of the included studies.

Neurophysiological and Psychosocial Mechanisms of Fibromyalgia: A Comprehensive Review and Call for An Integrative Model

Research into the neurobiological and psychosocial mechanisms involved in fibromyalgia has progressed remarkably in recent years. Despite this, current accounts of fibromyalgia fail to capture the complex, dynamic, and mutual crosstalk between neurophysiological and psychosocial domains. We conducted a comprehensive review of the existing literature in order to: a) synthesize current knowledge on fibromyalgia; b) explore and highlight multi-level links and pathways between different systems; and c) build bridges connecting disparate perspectives. An extensive panel of international experts in neurophysiological and psychosocial aspects of fibromyalgia discussed the collected evidence and progressively refined and conceptualized its interpretation. This work constitutes an essential step towards the development of a model capable of integrating the main factors implicated in fibromyalgia into a single, unified construct which appears indispensable to foster the understanding, assessment, and intervention for fibromyalgia.

Psychoeducation for Fibromyalgia Syndrome: A Systematic Review of Emotional, Clinical and Functional Related-Outcomes

Fibromyalgia Syndrome (FMS) is a chronic condition of widespread pain accompanied by several symptoms such as stiffness, fatigue, sleep problems, depression, anxiety, and cognitive deficits. To date, there is no specific treatment for FMS. The European League Against Rheumatism, and the majority of the international recommendations for managing FMS, has claimed psychoeducational intervention as the first step in FMS treatment for adequate symptoms management. However, scientific studies in this regard are scarce, diverse, and with contradictory findings. Results integration from analogous studies could provide a clear presentation of the real clinical value of psychoeducation in FMS. Therefore, the current systematic review aims at exploring the effect of psychoeducation on emotional, clinical, and functional symptoms of FMS patients and encourages researchers towards psychoeducation's procedure optimization and systematization. The systematic review was conducted according to the guidelines of the Cochrane Collaboration and PRISMA statements. The selected articles were evaluated using the Cochrane risk of bias (ROB) assessment tool. The selected articles were extracted from PubMed, Scopus, and Web of Science databases. The literature search identified 11 studies eligible for the systematic review. The ROB evaluation revealed that 2 of the 11 studies showed a low quality, the other 2 had a moderate quality, and the remaining 7 studies exhibited a high quality. Results showed that psychoeducation is generally included as an important first therapeutic step in multicomponent treatments for FMS. Moreover, psychoeducation generally seems to be quite beneficial in reducing emotional (i.e., number of days feeling emotionally well, general anxiety, depression levels, etc.) and clinical symptoms (levels of fatigue, morning stiffness, pain intensity, etc.), as well as increasing functional status (i.e., general physical function, morning fatigue, stiffness, etc.). Despite that psychoeducation´s clinical benefits are highlighted, there is scarce amount of research on psychoeducation beyond its usefulness as part of multicomponent treatments.

Fibromyalgia Increases Post-Operative Healthcare Utilization Following Total Hip Arthroplasty

INTRODUCTION

Pre-operative factors can complicate the post-operative course and increase healthcare utilization following total hip arthroplasty (THA). Fibromyalgia is not generally recognized as a modifiable risk factor prior to THA. The aim of this investigation was to assess the effect of fibromyalgia on post-operative healthcare utilization following THA.

METHODS

Patients who underwent primary THA from 2018 to 2019 were identified from a large national database using Current Procedural Terminology (CPT) and International Classification of Diseases, tenth revision (ICD-10) codes. Patient demographics, age, sex, and pre-operative opioid use were collected. Analysis compared patients who did and did not have fibromyalgia for post-operative healthcare utilization metrics; lengths of stay (LOS), 90-day post-operative opioid usages, dislocations, and emergency room visits. Independent t-testings were used to compare LOS, and rates of ongoing opioid use. Logistic regression analyses with adjusted Odds Ratios (aORs) evaluated the risk of dislocation and emergency room visit after adjusting for demographic characteristics and comorbidities.

RESULTS

Compared to those who did not have fibromyalgia, patients who had fibromyalgia experienced longer LOS (P<0.0001), increased odds of opioid use 90-days post-operatively (P<0.0001), as well as increased odds of hip dislocation (P<0.0001) and presentation to the emergency room (P<0.0001). Patients who had fibromyalgia were also more likely to be "frequent flyers" with >5 emergency room visits after THA (P<0.0001).

CONCLUSIONS

Fibromyalgia can complicate post-operative care following THA with increased LOS, higher rates of opioid use, and increased odds of dislocation and emergency room visits. As focus shifts to pre-operative optimization and risk stratification, more attention should be placed on fibromyalgia prior to THA.

The Indirect Effects of Recalled Trauma Severity on Pain Ratings among People with Fibromyalgia: a Moderated Mediation Model

Fibromyalgia syndrome (FM) is a chronic musculoskeletal condition that is accompanied by hypersensitivity to pain. Researchers have examined factors that affect pain ratings among people with FM, such as trauma, depressive symptoms, and coping; however, collectively, the interrelationships among this set of variables, and their relationships to pain, have not been examined. To better understand these relationships, a moderated-mediation model was used to examine how recalled trauma severity, depressive symptoms, relative emotion-focused coping relate to pain ratings. There were 501 participants who were primarily female, White, and ranged in age from 20 to 84 years. All participants had a physician's diagnosis of FM. The results indicated a significant moderated-mediation. Depressive symptoms significantly mediated the relationship between recalled trauma severity and pain ratings, such that greater trauma severity related to more depressive symptoms which in turn were associated with more pain. The mediation chain was moderated by relative emotion-focused coping (i.e., the proportion of emotion-focused coping compared to problem-focused coping), such that when relative emotion-focused coping was used at higher levels, the relationship between recalled trauma severity and depressive symptoms significantly weakened, reducing the indirect association between recalled trauma severity and pain ratings. The findings from the present study indicate that a treatment approach that includes a trauma-focused therapy such as exposure therapy or Emotional Awareness and Expression Therapy should be tested to determine whether these treatments can reduce the impact of past traumas, improve depressive symptoms, decrease pain ratings, and promote more adaptive coping among people with FM.
