Background: Fibromyalgia (FM) is a chronic musculoskeletal condition typically characterized by chronic pain, sleep disturbances, chronic fatigue, and cognitive problems. The present study aims to examine the efficacy of a pain neuroscience education program (PNE) in improving executive functions and pain intensity in patients with FM and compare them with those of standard treatment protocols., Methods: This blinded, controlled clinical trial will compare changes in executive function and pain intensity between two groups. The first group will receive standard treatment supplemented with PNE, consisting of ten sessions spread over five weeks, with each session lasting 40-45 min. The main objective of this method is to remodel cognitive and emotional reactions to pain, challenging the idea that pain is directly related to injury and highlighting the influence of emotions, sleep, and physical activity on pain perception. The second group will receive only standard pharmacological treatment. The study sample will include 62 adults diagnosed with FM, according to initial sample size estimates based on previous evidence. A baseline assessment of baseline characteristics will be performed, after which patients will be randomly assigned to the PNE group or the control group. The results of the intervention will be evaluated and statistically compared after 5 weeks. This protocol complies with all relevant ethical guidelines. It has been approved by two institutional committees (Reference: NR2006; Conbioethics:21-CEI-004-20,170,829)., Conclusion: It is anticipated that this intervention will be a cost-effective and superior alternative to standard treatments., Clinical Trial Registration: NCT05084300., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests.

Among patients with axial spondyloarthritis (axSpA), persistent pain remains a critical unmet need. In this review, we discuss the prevalence of chronic pain and fibromyalgia in patients with axSpA and examine the existing knowledge on the pathophysiology of chronic pain in SpA, osteoarthritis, and rheumatoid arthritis. Finally, we discuss the specific unmet needs that must be addressed to improve long-term outcomes in axSpA, specifically those that will improve chronic pain in this patient population., (Copyright © 2024 by the Journal of Rheumatology.)

Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread musculoskeletal pain and various associated symptoms. Non-pharmacological interventions have gained attention for managing FMS and improving patient outcomes. We reviewed past research to investigate the effects of traditional Chinese martial arts (TCMA) and stretching training (ST) on symptoms of patients with FMS. We searched Web of Science, Medline via PubMed, the Cochrane Library, and EMBASE from their inceptions to June 1, 2023. Across selected studies, we evaluated TCMA and ST using Fibromyalgia Impact Questionnaire (FIQ) scores, pain symptoms, fatigue levels, and sleep quality as outcome measures. Compared with control groups, participants receiving TCMA and ST interventions showed significantly lower FIQ scores (Standard Mean Difference (SMD) = -3.01, 95% Confidence Interval (CI) [-4.83,-1.19]), improved pain symptoms (SMD = -0.77, 95% CI [-1.07,-0.47]), less fatigue (SMD = 1.31, 95% CI [0.50,2.11]), and enhanced sleep quality (SMD = -0.55, 95% CI [-0.97,-0.12]). Subgroup analyses revealed that, irrespective of intervention duration, both TCMA and ST interventions were effective in relieving pain symptoms in these patients. ST interventions showed significant improvement in fatigue symptoms, while TCMA interventions positively influenced sleep quality. These findings highlight potential non-pharmalogical benefits of TCMA and ST interventions in managing FMS. However, future research should explore the optimal duration, frequency, intensity, and types of interventions for TCMA and ST and design targeted exercise intervention programs to study the effects of these interventions on different characteristics of FMS patients. Attention should be given to the effects of short-term interventions on improving fatigue symptoms, sleep quality, and pain relief, to provide more personalized and effective FMS treatment plans., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Describe trends in health care utilization, demographic characteristics and patient pathways among patients with musculoskeletal disorders (MSD) in Norway., Design: Register-based cohort study., Settings: Data were obtained from two Norwegian National registries; the Norwegian Control and Payment of Health Reimbursements Database (KUHR) and the Norwegian Patient Registry (NPR)., Subjects: Patients with MSD according to ICPC-2 and ICD-10 during 2014-2017., Main Outcome Measures: Patient pathways from the first contact and the following two years, described in a Sankey Diagram for all MSD patients and three common diagnoses: spine pain, osteoarthritis (OA) and fibromyalgia (FM)., Result: About 26% of the Norwegian population consulted PHC annually while 7% were treated in SHC. Mean age was 47 and 53 years in PHC and SHC, respectively. The proportion of women increased by age. Spine pain was the most common diagnosis; 33% and 22% in PHC and SHC, respectively. Over 90% visited a GP first, 50% of them were treated by PT and/or in SHC during follow-up. Patients visiting the PT first were less likely to be treated in SHC. OA patients were most likely to be treated by more than one health care professional (>70%)., Conclusion: One third of the Norwegian population consulted health care services due to MSD annually between 2014-2017. GP was the most consulted health care professional. Among MSD patients with long-term use of health care services, 50% were treated by a PT and/or in SHC in addition to a GP.

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.

Chronic pain (CP) affects about 30% of the global population and poses significant challenges to individuals and healthcare systems worldwide. The interactions between physiological, psychological, and social factors are crucial in the onset and development of CP conditions. This study aimed to evaluate the effectiveness of mindfulness-based intervention, examining its impact on perceived stress (PSS), depression and anxiety (BDI-II, PGWBI/DEP, SAS, STAI Y), sleep quality (PSQI), and mindfulness abilities (MAAS) in individuals with CP. Participants (N = 89, 84.3% female) underwent one of two diagnoses [fibromyalgia (FM) or low back pain (LBP)] and took part in an MBSR intervention. The mindfulness program proved effective in reducing PSQI scores (F = 11.97; p < 0.01) over time, independently of the type of diagnosis. There was also a marginal increase in trait mindfulness as measured by MAAS (F = 3.25; p = 0.07) in both groups. A significant difference between the two groups was found for the effect on PSS: F (1,87) = 6.46; p < 0.05. Mindfulness practice also reduced anxiety in FM and depressive symptoms in LBP, indicating a reduction in psychological distress among participants. Our findings suggest that mindfulness-based interventions may offer promising avenues for personalized pain management in clinical settings.

Background: Transcranial direct current stimulation (tDCS) might modulate neural activity and promote neural plasticity in patients with fibromyalgia (FM). This multi-group randomized clinical trial compared home-based active tDCS (HB-a-tDCS) on the left dorsolateral prefrontal cortex (l-DLPFC) or home-based sham tDCS (HB-s-tDCS), and HB-a-tDCS or HB-s-tDCS on the primary motor cortex (M1) in the connectivity analyses in eight regions of interest (ROIs) across eight resting-state electroencephalography (EEG) frequencies., Methods: We included 48 women with FM, aged 30 to 65, randomly assigned to 2:1:2:1 to receive 20 sessions during 20 minutes of HB-a-tDCS 2mA or HB-s-tDCS, over l-DLPFC or M1, respectively. EEG recordings were obtained before and after treatment with eyes open (EO) and eyes closed (EC)., Results: In the EC condition, comparing pre to post-treatment, the HB-a-tDCS on l-DLPFC decreased the lagged coherence connectivity in the delta frequency band between the right insula and left anterior cingulate cortex (ACC) (t = -3.542, p = .048). The l-DLPFC HB-a-tDCS compared to HB-s-tDCS decreased the lagged coherence connectivity in the delta frequency band between the right insula and left ACC (t = -4.000, p = .017). In the EO condition, the l-DLPFC HB-a-tDCS compared to M1 HB-s-tDCS increased the lagged coherence connectivity between the l-DLPFC and left ACC in the theta band (t = -4.059, p = .048). Regression analysis demonstrated that the HB-a-tDCS effect on the l-DLPFC was positively correlated with sleep quality. On the other hand, the HB-a-tDCS on l-DLPFC and HB-s-tDCS on M1 were positively correlated with pain catastrophizing., Conclusions: These results show that HB-a-tDCS affects the neural connectivity between parts of the brain that control pain's emotional and attentional aspects, which are most noticeable at lower EEG frequencies in a rest state. This effect on neural oscillations could serve as a neural marker associated with its efficacy in alleviating fibromyalgia symptoms., Clinical Trial Registration: identifier [NCT03843203]., Competing Interests: WC, National Council for Scientific and Technological Development - (CNPq), Brazil, ILST reported grants from National Council for Scientific and Technological Development, and Fundación de Amparo à Pesquisa do Estado do Rio Grande do Sul during the conduct of the study and PRSS grants from National Council for Scientific and Technological Development during the conduct of the study.

This study investigated the effect of Transcutaneous Electrical Nerve Stimulation (TENS) for fibromyalgia-like symptoms including chronic widespread musculoskeletal pain, fatigue, and/or gait impairment in twenty-five individuals with long-COVID. Participants were randomized to a high dose (intervention group, IG) or low dose (placebo group, PG) TENS device. Both groups received daily 3-5 h of TENS therapy for 4-weeks. The Brief Pain Inventory assessed functional interference from pain (BPI-I), and pain severity (BPI-S). The global fatigue index (GFI) assessed functional interference from fatigue. Wearable technology measured gait parameters during three 30-feet consecutive walking tasks. At 4-weeks, the IG exhibited a greater decrease in BPI-I compared to the PG (mean difference = 2.61, p = 0.008), and improved in gait parameters including stride time (4-8%, test condition dependent), cadence (4-10%, depending on condition), and double-support phase (12% in dual-task) when compared to baseline. A sub-group meeting the 2010 American College of Rheumatology Fibromyalgia diagnostic criteria undergoing high-dose TENS showed GFI improvement at 4-weeks from baseline (mean change = 6.08, p = 0.005). Daily TENS therapy showed potential in reducing functional interference from pain, fatigue, and gait alterations in long-COVID individuals. The study's limited power could affect the confirmation of certain observations. Extending the intervention period may improve treatment effectiveness., (© 2024. The Author(s).)

Background: The effectiveness of mindfulness meditation (MM) for the treatment of fibromyalgia syndrome (FMS) is unknown and needs to be updated., Objective: This study aimed at investigating the effectiveness of MM for the treatment of FMS., Study Design: A systematic review and meta-analysis., Methods: A comprehensive search of relevant studies published from the databases' inception through April 12, 2023 was conducted within the following databases: Cochrane Library, Embase, MEDLINE, PubMed, Clinicaltrials.gov, and PsycINFO. We included randomized controlled trials that reported at least one of the following outcome indicators: the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburg Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI), and the Perceived Stress Scale (PSS). Results are presented in terms of mean difference (MD), supplemented by 95% CIs The I2 statistic assessed heterogeneity across 3 distinct observational time frames. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework to appraise the robustness of the evidence., Results: Ten randomized controlled trials were selected from 1,377 citations (n = 818). Various MM regimens were reported (type of mindfulness, duration, schemes, and ingredients). Among 818 patients, very low to moderate evidence indicated that MM could reduce FIQ in the short-term (MD = -6.20; 95% CI,-8.51 to -3.89; P < 0.05; GRADE: moderate); a lower PSQI score (MD = -1.84; 95% CI, -3.35 to -0.33; P < 0.05; GRADE: very low); a reduce BDI score (MD = -3.26; 95% CI, -5.77 to -0.76; P < 0.05; GRADE: moderate); and a decreased PSS score (MD = -4.85; 95% CI, -8.22 to -1.49; P < 0.05; GRADE: very low). At medium-term follow-up, MM consistently reduced the BDI score (MD = -2.88; 95% CI, -4.98 to -0.79; P < 0.05; GRADE: moderate) and decreased the PSS score (MD = -2.76; 95% CI, -4.82 to -0.70; P < 0.05; GRADE: moderate) but there was no significant difference in FIQ scores (MD = -2.78; 95% CI, -6.32 to 0.76; P > 0.05; GRADE: low) and PSQI scores (MD = -1.28; 95% CI, -3.35 to -0.80; P > 0.05; GRADE: very low). However, at long-term follow-up, MM still reduced FIQ scores (MD = -6.09; 95% CI, -9.01 to -3.16; P < 0.05; GRADE: moderate)., Limitations: The relatively small sample size and the average quality of the included studies may have introduced biases. The time and method of meditation in the included studies were not completely unified, and there were confounding factors. Additionally, the limited amount of available literature is a challenge. Despite focusing on randomized controlled trials, there is heterogeneity among these studies. Future research should aim for larger, higher-quality studies to address these limitations and provide a more comprehensive understanding of MM's effectiveness in fibromyalgia management., Conclusions: Very low to moderate evidence shows that MM improves quality of life, relieves stress, and relieves insomnia and depression in patients with FMS in the short-term. Notably, the improvement in depression and stress levels continued into the medium-term period. Furthermore, quality of life improvement was discernible at long-term follow-up. This suggests that MM can be used as an adjunct therapy for FMS.International Prospective Register of Systematic Reviews (PROSPERO) Registration Number: CRD42023442356.

Background: Fibromyalgia is a complex condition that has long puzzled the medical community. Hypotheses to explain the chronic widespread pain associated with the disease have evolved significantly over the years. However, research efforts to identify disease-specific biomarkers and develop effective treatments have been largely unsuccessful., Objectives: The goals of this study were to review potential etiological biomarkers for fibromyalgia, focusing on micro-inflammation and metabolic syndrome, and to discuss the clinical implications of the review findings., Study Design: A narrative review., Methods: Relevant literature was obtained via Medline/PubMed, using the following search terms: fibromyalgia[ti] ("metabolic syndrome" OR "metabolic disease" OR biomarker*[ti] OR micro-inflammation OR sub-inflammation OR "low-level inflammation" OR "low-grade inflammation"). Results were filtered for the English language and screened for inclusion in the review., Results: Articles included in the review covered the topics of pain, immune response/inflammation, micro-inflammation, metabolic syndrome, gut dysbiosis, oxidative stress, and stress response. Various molecules have been proposed as pain biomarkers for fibromyalgia, including neurotransmitters, neuropeptides, growth factors, and cytokines with possible etiological relevance. Recent genome-wide expression profiling suggests connections among low-level inflammation, termed "micro-inflammation," and the upregulation of genes involved in antibacterial and innate immune system response as well as those involved in clinical features, including high body mass index (BMI) and comorbid depression, in a subgroup of fibromyalgia patients. A set of 5 differentially expressed inflammatory genes have been identified as potential biomarkers of a micro-inflammation fibromyalgia subtype. Proposed triggers of micro-inflammation include bacterial disease and gut dysbiosis. Metabolic syndrome may be causative or consequential, while comorbid depression may be associated with dysbiosis and/or micro-inflammation through the gut-immune-brain axis. A potential new treatment approach based on this information has been proposed., Limitations: External validation of potential etiological biomarkers is needed. Further investigations to ascertain the involvement of metabolic syndrome and gut dysbiosis and support the proposed treatment paradigm are warranted., Conclusion: Fibromyalgia is likely the result of multiple causative factors, genetic and environmental. To date, no clear, reliable etiological biomarker for fibromyalgia has been identified. The considerable variability among patients suggests the presence of multiple disease subtypes with different pathophysiological mechanisms. Effective treatment therefore requires a multimodal, multidisciplinary approach that targets each individual patient's pathophysiological features. The proposed treatment paradigm attempts to address multiple factors that have been implicated more recently in the development and maintenance of fibromyalgia, such as micro-inflammation, metabolic syndrome, and gut dysbiosis.

Objetive: Evaluate response to treatment and progression to rheumatoid arthritis (RA) in patients with fibromyalgia (FM) associated with elevated rheumatoid factor (RF)., Material and Methods: Prospective cohort study. The sample consisted of 124 patients with FM: 62 with high RF (>20 U/mL) and 62 with negative RF (0-20 U/mL). All patients were evaluated using FM treatment improvement score (FIQR) and progression to RA according to EULAR/ACR 2010 criteria at 6 and 12 months. Pearson's χ 2 test for homogeneity was used to relate variables of improvement to FM treatment and progression to RA., Results: The response to treatment was lower in the high RF group (24 and 20 patients improved at 6 and 12 months, respectively, compared to 45 and 38 patients in the negative RF group), with a significant difference. Progression to rheumatoid arthritis was similar in both groups (5 in the high RF group and 4 in the negative RF group), with a non-significant relationship., Conclusions: FM with elevated RF is associated with a poor therapeutic response but not with progression to RA., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare., (Published by Elsevier España, S.L.U.)

Background: The effectiveness of additive cognitive training in groups to the standard physical-medical therapy for primary and secondary fibromyalgia syndrome (p/sFMS) and a subsequent home-based self-training phase (STP) was analyzed., Methods: In the prospective controlled randomized study, 32 people with confirmed p/sFMS were included, whereby 4 patients could not be evaluated. During 2 weeks of acute inpatient therapy, the control group (CG; n = 12) received standard physical-medical therapy and the intervention group (IG, n = 16) also received social-communicative cognitive group training (once/day, 60 min). In the subsequent 3‑months, STP training was continued by both groups., Results: Outcome parameters at baseline (U1), at discharge (U2), and after a quarter year (U3) were pain, well-being/depressive mood, general health, and cognitive parameters (memory functions, cognitive speed). Both groups showed significant pain relief (U2 vs. U1), which was 10% more in the IG. A significant improvement in mood could be seen in both groups, but only the IG no longer achieved depressive values in the follow-up (U3). An improvement in the general state of health was also detected in both groups, which was only maintained in the IG until the end of the STP. Cognitive performance remained the same in the IG at U2, while there was a reduction in the CG; cognitive speed could only be further improved in the IG during the STP. Adding cognitive training to a standard physical-medical clinical therapy resulted in significant pain relief and improvement of depression in patients during a hospital stay., (© 2024.

Spa therapy is recommended to manage symptoms of fibromyalgia, but the physiological mechanisms underlying this improvement have been poorly studied. In an original study, we explored the effect of a 3-week rheumatology spa treatment for fibromyalgia patients on quality of life and with a symptom severity questionnaire. We present here the results of an ancillary study which explored three secondary criteria using objective measurement methods: diurnal actimetry for physical activity analysis, nocturnal actimetry for sleep analysis and heart rate variability. Eighty-three fibromyalgia patients were randomized to participate in an immediate 3-week rheumatological spa therapy, either a start within 6 weeks after inclusion (interventional group, n = 39) or a delayed, start 6 months after inclusion (control group, n = 44). Patients were asked to wear an actimeter (n = 56) to assess diurnal physical activity and sleep quality and a 24-h Holter ECG (n = 60) to assess nocturnal heart rate variability at baseline, 3 months and 6 months after inclusion. Time spent in sedentary and light physical activity was reduced to ∼30 min at 6 months in the interventional group (P = 0.027). Sleep quality and heart rate variability were not improved. Spa therapy made it possible to reduce sedentary activities in patients' daily life for up to 6 months afterwards, concomitant with the improvement in quality of life, pain and fatigue as highlighted in the original Thermalgi study., (Copyright © 2024 Elsevier Ltd.

Background and Purpose: Fibromyalgia is a chronic syndrome marked by intense musculoskeletal pain often refractory to pharmacological treatment. Although studies have shown that hypnosis improves fibromyalgia pain, gaps in experimental design limit their reliability. This work aimed to evaluate the effects of hypnosis on pain, mental health, sleep, and quality of life in participants with fibromyalgia chronic pain., Methods: In this prospective, parallel, randomized, controlled, blindly-evaluated trial, participants of both sexes (n = 49) diagnosed with fibromyalgia and with moderate to severe chronic pain attended 8 weekly 1-h sessions with a hypnotherapist. For the hypnosis group (n = 24), sessions consisted in induction of hypnotic trance followed by suggestions to promote analgesia. For the control group (n = 25), sessions consisted in casual unscripted conversation. Participants were assessed at baseline (7 days before), post-intervention (7 days after), and follow-up (3 months after). The primary outcome was pain intensity. The secondary outcomes were the sensory and affective dimensions of pain; pain unpleasantness; pain catastrophizing; anxiety and depression; sleep quality; fibromyalgia impact; and quality of life., Results: Hypnosis significantly reduced pain scores both at post-intervention and follow-up in comparison with baseline. The analgesic effect of hypnosis combined with pharmacological treatment lasted for at least 3 months and was superior to analgesia promoted by first- and second-line pharmacological treatment alone. Hypnosis significantly improved all parameters evaluated as secondary outcomes both at post-intervention and follow-up without inducing adverse events., Conclusion: Our results corroborate that clinical hypnosis is an effective and feasible tool for managing chronic pain and other symptoms of fibromyalgia., (Copyright © 2024.

Background/objective: Fibromyalgia is a non-inflammatory syndrome characterized by generalized muscle pain, with other symptoms. Numerous forms of physical training for this population have been studied through high-quality randomized clinical trials involving strength, flexibility, aerobic conditioning and multicomponent exercise interventions. This research evaluated the effectiveness of a functional exercise program at reducing pain, improving functional capacity, increasing muscle strength as well as improving flexibility, balance and quality of life in individuals with fibromyalgia., Methods: Eighty-two women with fibromyalgia were randomized into two groups. The functional exercise group performed functional exercises in 45-minute sessions twice per week for 14 weeks. The stretching exercise group performed flexibility exercises with the same duration and frequency. Outcome measures were: visual analog scale for widespread pain; Fibromyalgia Impact Questionnaire for health-related quality of life; Timed Up and Go test for functional performance; one-repetition maximum for muscle strength, Sit and Reach test on Wells bench for flexibility; Berg Balance Scale for balance; SF-36 for general quality of life., Results: After the intervention, the functional exercise group had a statistically significant reduction in pain (interaction p = 0.002), and improvement in health-related quality of life measured by the Fibromyalgia Impact Questionnaire (interaction p < 0.001) and in general health state domain of SF-36 (interaction p = 0.043) compared to the stretching exercise group. No significant differences between groups were found regarding improvements in functional capacity, muscle strength, flexibility or balance., Conclusion: Functional exercise training was effective at reducing pain and improving quality of life in patients with fibromyalgia compared to stretching exercises., Trial Registration: ClinicalTrials.gov Identifier: NCT03682588 First prospectively registered in March 2018., (© 2024.

Background: Chronic musculoskeletal pain syndromes, including fibromyalgia, are heterogeneous entities with a major socioeconomic burden. Multimodal treatment programmes have shown greater efficacy than conventional approaches for these patients, at least in the short term. A profound understanding of chronic musculoskeletal pain syndrome patients treated in multimodal treatment programmes is important for their development and to provide insight into these conditions., Aim: To provide a comprehensive and objective description of medical, psychosocial and sleep characteristics of the treatment-refractory chronic musculoskeletal pain syndrome patients treated at the multimodal treatment programmes provided by our tertiary service in Switzerland., Methods: This was a cross-sectional analysis of 202 refractory chronic musculoskeletal pain syndrome patients with or without a concomitant autoimmune disorder hospitalised between 2018 and 2022 in a 12-day Swiss multimodal treatment programme. They underwent a comprehensive self-assessment with eight different questionnaires and assessments by a psychiatrist, rheumatologist, pain specialist, occupational therapist and physiotherapist. Sleep assessment was performed via actigraphy. Clinical and demographic variables were selected by consensus of three experienced rheumatologists and chronic pain specialists. The Fibromyalgia Rapid Screening Test (FiRST), American College of Rheumatology (ACR)-2010 criteria (ACR2010) and Toronto Alexithymia Scale-20 (TAS-20) were also applied., Results: The mean age of the patients was 47 years (SD = 10), 73% were female, and 30% were obese. Half (50%) were not from Switzerland, and 12% came from conflict zones. Almost half (40%) lived alone. Back pain was the principal site (90%). Of the patients, 78% fulfilled the ACR2010 criteria for fibromyalgia, and 17% were diagnosed with an underlying immune-mediated disorder, mostly spondylarthritis. Pain since childhood occurred in 45% of the patients, and 68% had pain since adolescence. Disability financial aid had been pursued by 69%, and 46% were still awaiting a response. Psychiatric comorbidities were highly prevalent (73%), of which 56% consisted of depression. Of all patients, 15% were diagnosed with enduring personality changes after a catastrophic experience (EPCACE), and 10% had post-traumatic stress disorder. Alexithymia affected 34% of patients. Objective sleep disorder was observed in 78% of patients, and 41% were under opioid therapy., Conclusion: This analysis reveals the complex psychosomatic and socioeconomic patterns of the patients treated in Switzerland with refractory chronic musculoskeletal pain syndromes, often originating in childhood and adolescence. Obesity, immigration, social isolation, psychiatric comorbidities, sleep deprivation and opiate use, among others, stood out as target characteristics for further research.

Background: Fibromyalgia (FM) is a common soft tissue rheumatic disease. There is no established treatment plan for FM. Current treatments primarily focus on controlling symptoms and improving the quality of life. The aim of our study was to determine how connective tissue massage (CTM) and kinesiotaping (KT) affect pain and depression in patients with fibromyalgia, and to compare their effects on quality of life., Methods: Thirty-four patients diagnosed with fibromyalgia were included. Participants divided into two groups. Group 1: CTM (n = 17, mean age = 35.47 ± 6.84 years), Group 2: KT (n = 17, mean age = 34.00 ± 5.46 years). This study was initiated by obtaining sociodemographic information. Pain (Visual Analogue Scale (VAS)), pain characteristics (McGill Pain Questionnaire), disease impact on patients (Fibromyalgia Impact Questionnaire (FIQ)), depression (Beck's Depression Inventory (BDI)), and quality of life (Short Form-36 (SF-36)) were evaluated. All participants received electrotherapy (TENS and infrared treatment) for 25 min, 5 days a week for 4 weeks. CTM was applied 3 days a week, KT was applied 2 days a week for 4 weeks., Results: A significant improvement with very large effect size was found in VAS, McGill, FIQ, BDI, and SF-36 variables in both groups (p < 0.05). The change after 4 weeks of treatment was similar between groups in terms of all parameters (p > 0.05)., Conclusion: Both CTM and KT improved pain, disease effects depression, and quality of life. These two interventions, which are not superior, can be added to the treatment program for patients with fibromyalgia., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Introduction: Fibromyalgia (FM) is a multifaceted disease that is often associated with neuropsychiatric disorders and is burdened by a high degree of psychological distress. Non-pharmacological interventions, including physical exercise and complementary therapies, have shown satisfactory results for either physical or psychological FM symptoms., Methods: In this narrative review, we analyzed scientific evidence of moderate to high quality regarding the psychological and neurocognitive effects of physical therapies for FM. A total of 29 studies were selected after searching the PubMed and Google Scholar databases using the combination of terms « fibromyalgia», «psychological distress», «fibrofog», mental disorder», «aerobic exercise», «strength exercise», «Pilates», «Tai chi» and «Yoga»., Results: Aerobic exercise can improve depression, anxiety, stress, mental function and mood, thanks to the remodulation of neurotransmitters and hormones. Strength training, on the other hand, has been shown to alleviate mental confusion, anger and depression. Finally, mind-body disciplines appear to be effective for depression, anxiety, catastrophizing, memory and coping strategies. Based on these findings, we devised an ideal exercise program that could relieve the psychological distress of FM patients, thus interrupting the pathogenic neuroendocrine circuits that lead to the exacerbation of pain and other FM-related symptoms., Conclusions: Thanks to neuroendocrine remodulation, physical exercise may simultaneously improve the physical and mental health of FM patients. This narrative review collects current evidence on the effects of specific physical interventions on psychological and neurocognitive domains of FM patients and additionally provides an evidence-based training program that could be prescribed to FM patients with high psychological distress or neuropsychiatric symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Fibromyalgia is a chronic syndrome characterized by constant and generalized pain associated with sleep disturbance, depression, muscle stiffness, fatigue and cognitive disorders. Among non-pharmacological treatments, physical exercise stands out as a low-cost approach., Aim: To summarize and analyze evidence on the effects of resistance training on pain, functionality and quality of life in women with fibromyalgia., Methods: Following the PRISMA method, this systematic review included clinical trials assessing the effects of resistance training on pain, quality of life and functionality in female patients with fibromyalgia, regardless age. The researches were conducted in April 2021 in PubMed, Cochrane, Web of Science and Scopus databases, using the search strategy: ("fibromyalgia") AND ("strength training" OR "resistance training") AND ("quality of life" OR "pain" OR "functionality"). This study was registered in PROSPERO (CRD number: 42,021,246,245), and the risk of bias was assessed using the Version 2 of the Cochrane Risk-of-Bias tool (RoB 2)., Results: The search resulted in 125 studies (760 women), of which 16 were eligible for this review. Risk of bias assessment resulted in high (n = 5), moderate (n = 6) and low (n = 5) risks. Resistance training has proven to be an important non-pharmacological treatment tool for fibromyalgia, reducing pain, and improving patients' functionality and quality of life., Conclusion: The available evidence suggests that resistance training performed twice weekly, with progressive loads ranging from 40 to 80% of one-repetition maximum and a total duration of 4-24 weeks, appears to be an effective and safe therapeutic approach., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: This article reviews the potential etiologies of chronic widespread pain syndromes and outlines a practical approach to the management of patients with these disorders., Latest Developments: Recent updates to diagnostic criteria for primary chronic widespread pain syndromes have allowed for more effective diagnosis. Fibromyalgia is the most common presentation of chronic widespread pain, and the concept of nociplastic pain has been used to describe pain that is related to altered processing of pain sensory pathways. Research studies have provided a better understanding of the pathophysiology of the central augmentation that occurs in patients with nociplastic pain and fibromyalgia., Essential Points: Primary chronic widespread pain and fibromyalgia have established diagnostic criteria in which chronic pain involves multiple defined regions and occurs for longer than 3 months. Evaluation of chronic widespread pain should be directed by the clinical presentation. Neurologic disease can present with chronic widespread pain but is accompanied by associated signs and symptoms. Patients with chronic widespread pain benefit from effective communication that validates concerns, provides an understandable explanation of the presenting symptoms, and sets realistic expectations in outcomes using a comprehensive multimodal care plan., (Copyright © 2024 American Academy of Neurology.)

Fibromyalgia is one of the most prevalent chronic pain disorders. Fibromyalgia is characterised by generalised pain. In addition, patients with fibromyalgia often have co-morbidity. Since no cure is available, the treatment is based on symptom management, with physical exercise being the recommended first-line treatment. Different exercise modalities have been examined, including the practice of stretching exercises. The aim of the systematic review is to summarise the efficacy of stretching exercises on fibromyalgia symptoms and to study the content and the quality of the current evidence. The review followed the recommendations of the PRISMA statement. The search for articles was performed in April 2023. We searched on MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, AMED, PEDro, ClinicalTrials.gov and the Cochrane Collaboration Trials Register. The search was updated in March 2024. The protocol was registered in PROSPERO. Risk of Bias was assessed using the Cochrane Risk of Bias tool, and quality assessment was performed using the GRADE approach. In total, 2586 studies were found in the database searches, of which nine were included in the analysis. The primary outcome was pain. Secondary outcomes were self-reported quality of life, fatigue and physical and mental functioning. The available evidence shows that stretching exercises may improve pain, health-related quality of life and physical and mental functioning, but the level of evidence is low. The main limitation is due to issues with the heterogeneity of the interventions and small sample sizes. Trial registration: PROSPERO registration number CRD42023399614. Key Points • Stretching exercises show promise in the treatment of fibromyalgia. They may improve pain, health-related quality of life, physical functioning and mental health, but the level of evidence is low. • This study goes beyond previous research by presenting a more comprehensive and detailed analysis of the content and methodological quality of the current evidence. • Further research with clearly outlined protocols must be carried out to advance our understanding of the benefits of stretching exercises on fibromyalgia symptoms., (© 2024.

Balneotherapy, using heated natural mineral waters at 36-38 °C, presents a comprehensive treatment approach for Fibromyalgia Syndrome (FMS). This study aims to assess the effect of balneotherapy in reducing pain intensity, disability, and depression in patients with FMS. We want to assess this effect at just four time-points: immediately at the end of the therapy, and at 1, 3, and 6 months of follow-up. Following PRISMA guidelines, we conducted an aggregate data meta-analysis, registered in PROSPERO CRD42023478206, searching PubMed Medline, Science Direct, CINAHL Complete, Scopus, and Web of Science until August 2023 for relevant randomized controlled trials (RCTs) that assess the effect of balneotherapy on pain intensity, disability, and depression in FMS patients. Methodological quality was assessed using the Cochrane methodology, and the pooled effect was calculated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI) in a random-effects model. Sixteen RCTs were included in the meta-analysis. Balneotherapy is effective in reducing pain intensity (SMD - 1.67; 95% CI -2.18 to -1.16), disability (SMD - 1.1; 95% CI -1.46 to -0.7), and depression (SMD - 0.51; 95% CI -0.93 to -0.9) at the end of the intervention. This effect was maintained at 1, 3, and 6 months for pain intensity and disability. Balneotherapy improves both pain intensity and disability in patients with FMS, providing evidence that its positive effects are sustained for up to 6 months of follow-up. Nevertheless, it is important to note that the improvement in depression varies across different temporal phases., (© 2024. The Author(s).)

Purpose: This qualitative evidence synthesis aimed to identify and integrate findings where adults with fibromyalgia discussed how they managed their pain, and their perceptions of prescribed treatments from healthcare professionals., Materials and Methods: A comprehensive search strategy was implemented in PubMed, Scopus, ISI Web of Science, and Cinahl Plus databases. The GRADE-CERQual framework was used to evaluate the findings confidence. The findings were analyzed using an inductive thematic analysis approach., Results: A total of 35 studies ( N  = 728) were included. The confidence in the findings ranged from high to low confidence. Patients with fibromyalgia often do not benefit from seeking medical attention due to provider stigma, and have varying views on medication effectiveness commonly reporting feeling like "walking chemists." They find mixed effects from exercise, and consider psychological support essential, although the benefits of cognitive-behavioral therapy were controversial. Combining cognitive-behavioral therapy with physical exercise appears more effective, while natural and complementary therapies have short-term benefits and high costs., Conclusions: Pain management is a source for frustration and an unmet need for patients with fibromyalgia. The current findings provide crucial insight for providers and researchers; and support the need for fibromyalgia phenotyping and precision medicine approaches to pain management.Implications for RehabilitationChronic widespread pain is the defining feature of fibromyalgia, yet pain reduction is often an unmet need for these individuals.The lack of effective treatments resulting in long-term relief proves frustrating for patients and healthcare providers.Rehabilitation professional should consider the unique insight into this complex, heterogeneous condition that this qualitative synthesis provides to better understand their patient's perspective on pain management.Given the differing perspectives on pain treatment approaches individuals with fibromyalgia report, providers should discuss with each patient their current strategies and take a patient-centered, individualized approach to form an effective treatment plan.

Fibromyalgia (FM) is a common chronic pain condition for which acupuncture treatment is increasingly utilized. However, there is no universally accepted measure to predict whether a specific patient will benefit from acupuncture. This is a single-center, single-blind, sham-controlled, randomized, noncrossover, longitudinal trial of 76 subjects with FM, assigned to either electroacupuncture (EA) or a placebo control, mock laser (ML) acupuncture. Outcome measures included clinical pain severity (Brief Pain Inventory [BPI]), degree of nociplastic pain (Fibromyalgia Survey Questionnaire), and pressure pain tolerance (PPtol). Baseline measures of temporal summation of pain and expectations for treatment relief were used as predictors. Individuals in both treatment groups experienced significant reductions in BPI (EA: P < .001, ML: P = .018) and Fibromyalgia Survey Questionnaire (EA: P = .032, ML: P = .002) after treatment; however, neither group showed a significant increase in PPtol. Lower temporal summation at baseline was correlated with greater post-treatment improvement in BPI in the EA group (rho = .389, P = .025) but not in the ML group (rho = -.272, P = .109). Lower-baseline temporal summation was correlated with greater decreases in PPtol following EA (rho = .400, P = .040), whereas the opposite was seen for ML (rho = -.562, P = .001). Treatment expectancy at baseline was not correlated with any outcome after EA or ML treatments. Our results support using a quantitative sensory testing metric, temporal summation of pain, but not expectations, to predict analgesia following acupuncture treatment for pain. PERSPECTIVE: A randomized study of acupuncture in FM found baseline temporal summation, but not expectations of pain relief, to be predictive of treatment response.

Objective: The aim of this experimental study was to determine which manual therapy approach is more effective in addressing health status by improving symptoms (sensory, cognitive, emotional, and social) in patients with fibromyalgia., Material and Methods: A quasi-randomized clinical trial with 3-month follow-up was conducted in 52 female patients (age 52.5 ± 8.1 years) affected by rheumatologist-diagnosed Fibromyalgia and evaluated at the Asociación de Fibromialgia y Síndrome de Fatiga Crónica (AFINSYFACRO) in Móstoles and AFIBROM, Madrid, Spain. Two manual therapy approaches were applied: the myofascial technique approach (MTA) and Maitland Mobilization Approach (MMA). The study examined the following outcomes: Widespread Pain, Symptom Severity, Impact on Quality of Life, Perceived Pain, Sensitization-Associated Pain, Sleep Quality, Physical Activity, and Psychological, Cognitive, and Emotional Factors. Patient Satisfaction was also assessed., Results: No significant differences were found between groups over time for most variables. However, the MTA group showed significant improvements in pain intensity, central sensitization, general health, sleep quality, and anxiety compared with the MMA group., Conclusions: Despite the lack of between-group differences in all variables over time, MTA may be useful in the treatment of fibromyalgia, reducing pain, central sensitization, and negative emotional symptoms, as well as improving general health and sleep quality. Due to problems during the study, randomization was abandoned. This problem becomes a virtue by taking advantage of the situation to apply statistical compensation methods, which will serve as a guide for future research that suffers from this problem. We suggest the inclusion of longer follow-up periods in future studies., Competing Interests: Declaration of competing interest The authors certify that they have no affiliations with or financial involvement in any organization or entity with a direct financial interest in the subject matter or materials discussed in the article., (Copyright © 2024 The Authors.

Fibromyalgia, characterized as a complex chronic pain syndrome, presents with symptoms of pervasive musculoskeletal pain, significant fatigue, and pronounced sensitivity at specific anatomical sites. Despite extensive research efforts, the origins of fibromyalgia remain enigmatic. This narrative review explores the intricate relationship between muscle oxygen saturation and fibromyalgia, positing that disruptions in the oxygenation processes within muscle tissues markedly influence the symptom profile of this disorder. Muscle oxygen saturation, crucial for muscle function, has been meticulously investigated in fibromyalgia patients through non-invasive techniques such as near-infrared spectroscopy and magnetic resonance imaging. The body of evidence consistently indicates substantial alterations in oxygen utilization within muscle fibers, manifesting as reduced efficiency in oxygen uptake during both rest and physical activity. These anomalies play a significant role in fibromyalgia's symptomatology, especially in terms of chronic pain and severe fatigue, potentially creating conditions that heighten pain sensitivity and accumulate metabolic byproducts. Hypothesized mechanisms for these findings encompass dysfunctions in microcirculation, mitochondrial irregularities, and autonomic nervous system disturbances, all meriting further research. Understanding the dynamics of muscle oxygen saturation in fibromyalgia is of paramount clinical importance, offering the potential for tailored therapeutic approaches to alleviate symptoms and improve the quality of life for sufferers. This investigation not only opens new avenues for innovative research but also fosters hope for more effective treatment strategies and improved outcomes for individuals with fibromyalgia., (Copyright © 2024 Copyright: © 2024 Medical Gas Research.)

There are estimated tens of millions of individuals throughout the world suffering from a variety of postinfectious sequela following infection with severe acute respiratory syndrome coronavirus 2 also commonly referred to as long coronavirus disease (COVID). Long COVID is providing an opportunity for the field of rheumatology to explore the relationship between similar syndromes including fibromyalgia seen in patients with underlying inflammatory and noninflammatory rheumatic diseases, as well as other postacute infectious sequela and bring our field's traditional skill sets to bear on improving our understanding of these disorders and the care of such patients., Competing Interests: Disclosure None., (Copyright © 2024 Elsevier Inc.

Fibromyalgia (FM) is a chronic syndrome of unknown etiology, although many studies point to inflammation, oxidative stress, and altered mitochondrial metabolism as some of the cornerstones of this disease. Despite its socioeconomic importance and due to the difficulties in diagnosis, there are no effective treatments. However, the use of non-drug treatments is increasingly becoming a recommended strategy. In this context, the effects of supplementation of FM patients with an olive (poly)phenol, vitamin C, and vitamin B preparation were investigated in this work, analyzing complete blood count, biochemical, lipid, and coagulation profiles, and inflammation and oxidation status in blood samples. To gain a better understanding of the molecular mechanisms and pathways involved in the etiology of FM, a proteomic study was also performed to investigate the mechanisms of action of the supplement. Our results show that the nutraceutical lowers the lipid profile, namely cholesterol, and improves the oxidative status of patients as well as their quality of life, suggesting that this product could be beneficial in the co-treatment of FM.

Background: Fibromyalgia syndrome (FMS) affects 2% to 4% of people, with increasing prevalence in Saudi Arabia reaching 13.4%. FMS can occur in adolescents, known as juvenile-onset fibromyalgia (JFM) with comorbidities including depression, anxiety, and psychological stress. Our patient presented to the child and adolescent psychiatry clinic at King Saud University Hospital Medical City. A year before coming to our clinic, at the age of 15 she was initially diagnosed with JFM followed by a comorbid persistent depressive disorder., Methods: As a novel treatment method, a combination treatment approach was used, including a pharmacological intervention with Duloxetine, and a non-pharmacological intervention with interpersonal psychotherapy for adolescents. She completed 16 weeks of therapy while monitoring for duloxetine response and side effects., Results: Depressive symptoms were in remission by treatment's end and continued to be in her first month posttreatment follow-up, and the FMS symptoms were also controlled., Conclusion: Our present case highlights a combined approach to treat depression and JFM in adolescents as a novel intervention method thus we strongly recommend utilizing it for similar cases., Competing Interests: The authors have no funding and no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Fibromyalgia (FM), classified by ICD-11 with code MG30.0, is a chronic debilitating disease characterized by widespread pain, fatigue, cognitive impairment, sleep, and intestinal alterations, among others. FM affects a large proportion of the worldwide population, with increased prevalence among women. The lack of understanding of its etiology and pathophysiology hampers the development of effective treatments. Our group had developed a manual therapy (MT) pressure-controlled custom manual protocol on FM showing hyperalgesia/allodynia, fatigue, and patient's quality of life benefits in a cohort of 38 FM cases (NCT04174300). With the aim of understanding the therapeutic molecular mechanisms triggered by MT, this study interrogated Peripheral Blood Mononuclear Cell (PBMC) transcriptomes from FM participants in this clinical trial using whole RNA sequencing (RNAseq) and reverse transcription followed by quantitative Polymerase Chain Reaction (RT-qPCR) technologies. The results show that the salt-induced kinase SIK1 gene was consistently downregulated by MT in FM, correlating with improvement of patient symptoms. In addition, this study compared the findings in a non-FM control cohort subjected to the same MT protocol, evidencing that those changes in SIK1 expression with MT only occurred in individuals with FM. This positions SIK1 as a potential biomarker to monitor response to MT and as a therapeutic target of FM, which will be further explored by continuation studies.

Background: This study is a randomized controlled, biopsychosocial study investigating the effectiveness of pain neuroscience education (PNE) and motor imagery-based exercise protocol (MIEP) on fibromyalgia pain., Methods: Our study has four groups (MIEP n = 12, PNE n = 12, MIEP + PNE n = 14, Control n = 12) and all participants (n = 50) consist of patients diagnosed with fibromyalgia with chronic back pain. The primary outcome measure was pain intensity, and secondary outcome measures were beliefs, kinesiophobia, anxiety-depression, cognitive-mood, self-esteem, and body awareness., Results: A statistically significant decrease in pain intensity was observed in all experimental groups, without any group being superior (Visual Analog Scale [VAS]: MIEP + PNE p = .003, 95% confidence interval [CI], -4.7078 to -0.9922; MIEP p = .003, 95% CI, -5.4806 to -1.0194; PNE p = .002, 95% CI, -3.6139 to -1.5461). There was a significant improvement in organic beliefs in both groups where PNE was applied (MIEP + PNE: p = .017, 95% CI, -7.8211 to -0.3189; PNE: p = .003, 95% CI, -9.7999 to -0.0401). A significant superiority in organic pain beliefs was detected in the MIEP + PNE group compared to the control group (p = .008, 95% CI, 1.7241-9.4959)., Conclusions: According to this study, in which MIEP and PNE were combined, there was a decrease in pain intensity when both applications were applied together and when they were applied one by one. MIEP has improved her motor imagery ability, improved pain and increased body awareness. PNE has improved people's organic pain beliefs; removed people from fears, catastrophizing, and negative thoughts about pain; improved easier management of psychological processes and cognitive-emotion regulation ability., (© 2024 The Author(s).

Introduction: Walking is a beneficial healthy lifestyle for fibromyalgia patients as it reduces the intensity of pain and fatigue experienced and improves quality of life. In this context, self-efficacy and commitment are potential predictors of walking for women with fibromyalgia. Present study aims at examining the moderation role of exercise commitment in the association between self-efficacy for walking and walking behavior in this population., Method: It is a cross‑sectional study. A total of 132 women with fibromyalgia participated (mean age = 57.63, SD = 10.44) between January and December 2018. Self-efficacy about walking was assessed through Spanish version of self-efficacy scale for physical activity scale (SEPAS) and exercise commitment through ad-hoc questionnaire (two Likert-type items about the committed action of physical activity). Walking behavior was measured using accelerometers for seven consecutive days. Pain and fatigue prior to placement of the accelerometer were evaluated as possible covariates. Regarding medical history, time since onset of symptoms (i.e. pain, fatigue) and since diagnosis, and medication were also assessed as possible covariates., Results: A moderation effect of exercise commitment was found in the relationship between self-efficacy on walking behavior (B = 10.48, p = .021, 95%, CI = 0.61 to 6.79). Post-hoc analyses showed a significant and positive relationship between self-efficacy and walking only with high commitment to physical activity (t = 10.08, p = .027, 95%, CI = 3.77 to 5.64)., Conclusions: Self-efficacy for walking and commitment should be assessed and potentially targeted when focusing on increasing walking in women with fibromyalgia. Key Points • Associations between walking self-efficacy and exercise engagement provide indications of modifiable targets for promoting an active lifestyle in fibromyalgia. • When patients feel engaged in their physical exercise pattern (walking), patients feel more able to perform the behavior. • Rehabilitation interventions, focused on chronic pain, should contemplate the promotion of self-efficacy and engagement., (© 2024.

Background: Exercise intensity is a key component of an exercise prescription. This meta-analysis aimed to investigate the treatment effect of different exercise doses on fibromyalgia syndrome., Methods: PubMed, Embase, Web of Science, and the Cochrane Library were searched from their inception until 29 December 2023. The studies were subjected to screening using a 2-phase approach by 2 independent reviewers. Reference lists of the included studies were manually searched. Two independent reviewers extracted information regarding the origin, characteristics of study participants, eligibility criteria, characteristics of interventions, outcome measures, and main results using a pre-defined template., Results: This meta-analysis encompassed a total of 19 randomized controlled trials comprising 857 patients. Compared with the low compliance/uncertain group according to ACSM, the high compliance group showed better effectiveness in general condition improvement (SMD: -1.15 > -0.71), pain relief (SMD: -1.29 > -1.04), sleep quality enhancement (SMD: -1.66 > -1.08), and fatigue relief (SMD: -1.72 > -1.32). However, there was no difference in the improvement of mental health between the two groups (SMD: -0.93 > -0.92)., Conclusion: Compared to the ACSM group with compliance uncertainty (<70%), the high compliance group showed improvement in general conditions, pain, sleep quality, and fatigue. However, there was no difference in terms of mental health., (© 2024 The Author(s). Musculoskeletal Care published by John Wiley & Sons Ltd.)

Fibromyalgia (FM) is a complex and poorly understood disorder characterized by chronic and widespread musculoskeletal pain, of which the etiology remains unknown. Now, the disorder of the gut microbiome is considered as one of the main causes of FM. This study aimed to investigate the potential benefits of fecal microbiota transplantation (FMT) in patients with FM. A total of 45 patients completed this open-label, randomized, nonplacebo-controlled clinical study. The numerical rating scale scores in the FMT group were slightly lower than the control group at 1 month (P > .05), and they decreased significantly at 2, 3, 6, and 12 months after treatment (P < .001). Besides, compared with the control group, the Widespread Pain Index, Symptom Severity, Hospital Anxiety and Depression Scale, and Pittsburgh Sleep Quality Index scores were significantly lower in the FMT group at different time points (P < .001). After 6 months of treatment, there was a significant increase in serotonin (5-hydroxytryptamine) and gamma-aminobutyric acid levels (P < .001), while glutamate levels significantly decreased in the FMT group (P < .001). The total effective rate was higher in the FMT group (90.9%) compared to the control group (56.5%) after 6 months of treatment (P < .05). FMT can effectively improve the clinical symptoms of FM. With the close relations between the changes in neurotransmitters and FM, certain neurotransmitters may serve as a diagnostic marker or potential target for FM patients. PERSPECTIVE: FMT is a novel therapy that aims to restore the gut microbial balance and modulate the gut-brain axis. It is valuable to further explore the therapeutic effect of FMT on FM. Furthermore, certain neurotransmitters may become a diagnostic marker or a new therapeutic target for FM patients., (Copyright © 2024. Published by Elsevier Inc.)

This randomized controlled pilot study compared the efficiency of exercise on a vibration machine combined with needle therapy versus needle therapy alone in managing fibromyalgia symptoms and well-being among older adults. Conducted at King Khalid Hospital in Alkharj, Saudi Arabia, the study involved eighty-six patients aged 60 to 67 years. Participants were randomly assigned to either the VENT (Vibration Exercise Device) group or the NT (Needle Therapy) group. The VENT group underwent 10-minute vibration training sessions twice a week, paired with 30-minute needle acupuncture sessions once a week, while the NT group received needle therapy alone. Both interventions were carried out over 12 weeks. Pre- and post-intervention assessments measured disability, pain, balance, and quality of life. Data analysis showed that 94.1% of participants completed the study, with significant improvements in disability observed in the VENT group. Both groups demonstrated significant improvements in pain, balance, and well-being. However, post-intervention comparisons favored the VENT group, showing significantly better outcomes. The findings suggest that combining vibratory exercise with needle therapy offers enhanced benefits for older adults with fibromyalgia., Competing Interests: Declaration of competing interest The authors confirm no conflict of interest with no financial support concerning the material used in the study., (Copyright © 2024 Elsevier Inc.

Background: The diagnosis, etiology, and optimal management of fibromyalgia remains contentious. This uncertainty may result in variability in clinical management. We conducted a systematic review and meta-analysis of cross-sectional studies examining physicians' knowledge, attitudes, and practices regarding fibromyalgia., Methods: We searched MEDLINE, Embase, and PubMed from inception to February 2023 for cross-sectional surveys evaluating physicians' attitudes toward, and management of, fibromyalgia. Pairs of independent reviewers conducted article screening, data extraction, and risk of bias assessment in duplicate. We used random-effects meta-analysis to pool proportions for items reported by more than one study and the Grading of Recommendations Assessment, Development, and Evaluation approach to summarize the certainty of evidence., Results: Of 864 citations, 21 studies (8904 participants) were eligible for review. Most physicians endorsed fibromyalgia as a distinct clinical entity (84%; 95% confidence interval [CI], 74-92), and half (51%; 95% CI, 40-62) considered fibromyalgia a psychosocial condition. Knowledge of formal diagnostic criteria for fibromyalgia was more likely among rheumatologists (69%, 95% CI, 45-89) versus general practitioners (38%, 95% CI, 24-54) (P = .04). Symptom relief was endorsed as the primary management goal by most physicians (73%, 95% CI, 52-90). Exercise, physiotherapy, antidepressants, nonsteroidal anti-inflammatory drugs, and non-opioid analgesics were most endorsed for management of fibromyalgia, but with wide variability between surveys. Opioids and most complementary and alternative interventions (e.g., homeopathy, chiropractic, and massage) received limited endorsement., Conclusion: There is moderate certainty evidence to suggest that physicians are divided regarding whether fibromyalgia is a biomedical or psychosocial disorder. Physicians typically prioritize symptom relief as the primary goal of management, and often endorse management with exercise, non-opioid analgesics, nonsteroidal anti-inflammatory drugs, antidepressants, and physiotherapy (moderate to high certainty evidence); however, important practice variation exists., (Copyright © 2024 the Author(s).

Objective: This study investigated the efficacy of combining at-home anodal transcranial direct current stimulation (tDCS) of the left primary motor cortex (M1) with mindfulness meditation (MM) in fibromyalgia patients trained in mindfulness., Methods: Thirty-seven patients were allocated to receive ten daily sessions of MM paired with either anodal or sham tDCS over the primary motor cortex. Primary outcomes were pain intensity and quality of life. Secondary outcomes were psychological impairment, sleep quality, mood, affective pain, mindfulness level, and transcranial magnetic stimulation (TMS) measures of cortical excitability. Outcomes were analyzed pre- and post-treatment, with a one-month follow-up., Results: We found post-tDCS improvement in all clinical outcomes, including mindfulness level, except for positive affect and stress, in both groups without significant difference between active and sham conditions. No significant group*time interaction was found for all clinical and TMS outcomes., Conclusions: Our findings demonstrate no synergistic or add-on efffect of anodal tDCS of the left M1 compared to the proper effect of MM in patients with fibromyalgia., Significance: Our findings challenge the potential of combining anodal tDCS of the left M1 and MM in fibromyalgia., (Copyright © 2024 International Federation of Clinical Neurophysiology.

Persons with fibromyalgia experience a diverse set of symptoms. Recommendations for management generally focus on multidisciplinary approaches involving multiple modalities. Mobile apps can be an essential component for self-management, yet little is known about how persons with fibromyalgia use mobile apps for health-related purposes. A cross-sectional survey (N = 663) was conducted to understand the real-world use of apps among persons with fibromyalgia. The survey included 2 main foci: 1) eHealth literacy and use of information sources, and 2) mobile app use patterns and preferences for health-related purposes, including the types of apps used and usage characteristics of apps currently in use, as well as those that had been discontinued. Respondents' average eHealth literacy as measured by eHealth Literacy Scale (eHEALS) was 31.4 (SD = 7.1), and they utilized diverse information sources. Approximately two-thirds of the sample used mobile apps; the remaining one-third did not. Diverse health management needs were represented in the apps reported, including scheduling/time management, notetaking, fitness, and wellness. Compared to apps that had been discontinued, participants rated apps that they still used higher in terms of ease of use and used them more frequently. Reasons for discontinuing app use included issues with privacy, the effort required, lack of interest, and lack of perceived quality. Other reasons for app nonuse were lack of awareness and how-to knowledge, indicating that disseminating information about apps and addressing other barriers, such as providing user support, are critical to increasing uptake. These study findings can inform both app design and dissemination. PERSPECTIVE: This article presents how persons with fibromyalgia use mobile apps to manage their health. The findings could inform the development of digital interventions or programs for this population., (Copyright © 2024 United States Association for the Study of Pain, Inc. Published by Elsevier Inc.

Objective: To explore the potential effectiveness of myofascial release compared to passive muscle stretching and to a control group in modulating pain intensity and health status in adults diagnosed with fibromyalgia (FM)., Materials and Methods: A preliminary randomized controlled clinical trial was conducted, consisting of eight weekly sessions. The participants were divided into three groups: myofascial release group (RG = 13), a muscle stretching group (SG = 13), and a control group (CG = 12), which received advice from a rheumatologist. The outcomes measured were the visual analogue pain scale (VAS), the fibromyalgia impact questionnaire (FIQ) (representing health status), and the number of painful areas. Univariate analyzes of covariance (ANCOVA) were performed at baseline, after 4 weeks (during treatment), after 8 weeks (post-treatment), and after 12 weeks (follow-up). The International Physical Activity Questionnaire (IPAQ), the Beck Depression Inventory (BDI) and the Pain Catastrophizing Scale (PCS) were included as covariates. Clinical trial registration number: NCT: 03408496., Results: After eight weeks, the RG showed lower VAS scores compared to the CG (mean difference 95% CI: -5.10 to -1.26) and the SG (mean difference 95% CI: -4.9 to -0.23) with no difference between the SG and the CG. The total FIQ score for the RG was lower than the CG after 4 weeks (95% CI: -49.92 to -5.61), and 8 weeks (mean difference 95% CI: -52.72 to -15.73), although there was no difference between the RG and SG, as well as between the SG and CG, at both time points. The number of painful body areas was similar in all groups at the four time points., Conclusion: Preliminary results suggest that the RG possibly showed greater improvements in pain intensity and health status compared to the CG, and possibly greater improvements in pain intensity compared to the SG.

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., Trial Registration Number: NCT04304664., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

To evaluate the level of knowledge and adherence to Clinical Practice Guidelines on fibromyalgia of physiotherapists in Spain. A cross-sectional study using an ad-hoc online survey was implemented to assess aspects on the assessment, treatment, and decision of the length of the therapeutic approach on fibromyalgia. Based on the results, professionals were classified as adherent, partially adherent, or non-adherent. The level of agreement with several statements on the condition was also evaluated across the professionals surveyed to evaluate the potential consensus. A total of 240 physiotherapists met inclusion criteria, amongst which 68 (28.33%) were adherent. The academic level of studies (Chi-square = 48.601, p-value = 0.001) and having had previous training in fibromyalgia (Chi-square = 151.011, p-value = 0.001) displayed statistically significant differences across adherence-based groups. Consensus was reached for 15 out of 24 statements. Our findings highlight the presence of an acceptable level of knowledge and adherence to clinical practice guidelines in the field of fibromyalgia among physiotherapists in Spain.Practice implicationsOur results also reveal the existence of an evidence-to-practice gap in the field, with potential room for improvement: further efforts on promoting and reinforcing the importance of evidence-based therapies are needed, from university teaching plans to clinical updates for daily practice., (© 2024.

Background: Homeopathy has been used in observational and controlled studies to treat patients with fibromyalgia (FM), but none has previously used the remedy Cannabis sativa ., Case History: A 51-year-old female patient presenting with diffuse pain and sleep disorder was diagnosed with FM using the relevant American College of Rheumatology criteria. She reported having 18 tender points, a pain score (visual analog scale, VAS) of 9.0, and a well-being VAS of 5.0. She was prescribed Cannabis sativa 6 cH, five drops sublingually thrice a day., Results: After 2 months, she returned asymptomatic, with 0 tender points, pain VAS of 0, and well-being VAS of 9.0. The Modified Naranjo Criteria for Homeopathy score was equal to +9, suggesting the clinical outcome was causally attributable to the medicine prescribed., Conclusion: This case study reveals the positive role of homeopathic treatment in FM. Studies using a randomized controlled design, including pragmatic trials to determine treatment effectiveness in real-world clinical practice, are indicated in this field., Competing Interests: None declared., (Faculty of Homeopathy.

Purpose: Patient education is a core component of treating fibromyalgia and central sensitization disorders. We sought to evaluate whether patients with fibromyalgia prefer virtual or in-person educational classes as part of their treatment program, identify underlying factors with their educational modality choice, and highlight benefits or barriers associated with in-person or online educational sessions., Design: A cross-sectional survey with a qualitative feedback component was utilized., Methods: A voluntary, anonymous survey was distributed to all participants (in-person and virtual) of the fibromyalgia and chronic fatigue clinic treatment program from October 2021 through March 2022., Results: In total 90 participants completed the survey. Nearly all (94%) agreed that the pathophysiologic education was relevant and valuable and (98%) agreed to feeling confident with implementing management strategies. Perceived connection between the participants varied between groups (85% of in-person vs 48% of online; p < .001), as did perceived engagement (100% of in-person vs 71% of online; p = .001)., Conclusions: Patients value education and find it useful in treating fibromyalgia, regardless of the educational modality. The online group reported more limitations including less engagement, class participation, and connection with peers., Clinical Implications: As virtual education platforms become more widely available and may be easier to access than in-person options, it is important to understand patient preferences, benefits, and disadvantages of educational modalities to ensure education and patient outcomes remain equitable., (Copyright © 2024.

Background: International guidelines have recommended cognitive behavioural therapy, including acceptance and commitment therapy (ACT), as it offers validated benefits for managing fibromyalgia; however, it is inaccessible to most patients. We aimed to evaluate the effect of a 12-week, self-guided, smartphone-delivered digital ACT programme on fibromyalgia management., Methods: In the PROSPER-FM randomised clinical trial conducted at 25 US community sites, adult participants aged 22-75 years with fibromyalgia were recruited and randomly assigned (1:1) to the digital ACT group or an active control group that offered daily symptom tracking and monitoring and access to health-related and fibromyalgia-related educational materials. Randomisation was done with a web-based system in permuted blocks of four at the site level. We used a blind-to-hypothesis approach in which participants were informed they would be randomly assigned to one of two potentially effective therapies under evaluation. Research staff were not masked to group allocation, with the exception of a masked statistics group while preparing statistical programming for the interim analysis. The primary endpoint was patient global impression of change (PGIC) response rate at week 12. Analyses were by intention to treat. The trial was registered with ClinicalTrials.gov, NCT05243511 (now fully closed)., Findings: Between Feb 8, 2022, and Feb 2, 2023, 590 individuals were screened, of whom 275 (257 women and 18 men) were randomly assigned to the digital ACT group (n=140) and the active control group (n=135). At 12 weeks, 99 (71%) of 140 ACT participants reported improvement on PGIC versus 30 (22%) of 135 active control participants, corresponding to a difference in proportions of 48·4% (95% CI 37·9-58·9; p<0·0001). No device-related safety events were reported., Interpretation: Digital ACT was safe and efficacious compared with digital symptom tracking in managing fibromyalgia in adult patients., Funding: Swing Therapeutics., Competing Interests: Declaration of interests RMG reports being a consultant and receiving stock options or bond holdings from Swing Therapeutics.

To evaluate the effectiveness of photobiomodulation (PBM) in conjunction with an aerobic exercise program (AEP) on the level of pain and quality of life of women with fibromyalgia (FM)., Methods: A double-blinded randomized controlled trial in which 51 participants with FM were allocated into 4 groups: control group (CG) (n = 12); active PBM group (APG) (n = 12); AEP and placebo PBM group (EPPG) (n = 13); AEP and active PBM group (EAPG) (n = 14). AEP was performed on an ergometric bicycle; and a PBM (with an increase dosage regime) [20 J, 32 J and 40 J] was applied using a cluster device. Both interventions were performed twice a week for 12 weeks. A mixed generalized model analysis was performed, evaluating the time (initial and final) and group (EAPG, EPPG, APG and CG) interaction. All analyses were based on intent-to-treat for a significance level of p ≤ 0.05., Results: The intra-group analysis demonstrated that all treated groups presented a significant improvement in the level of pain and quality of life comparing the initial and final evaluation (p < 0.05). Values for SF-36 and 6-minute walk test increased significant in intragroup analysis for EPPG comparing the initial and final evaluation. No intergroup differences were observed., Conclusions: Both exercised and PBM irradiated volunteers present improvements in the variables analyzed. However, further studies should be performed, with other PBM parameters to determine the best regime of irradiation to optimize the positive effects of physical exercises in FM patients., (© 2024.
