Is connective tissue massage effective in individuals with fibromyalgia?

OBJECTIVES: The aim of the study was to examine the effectiveness of Clinical Pilates exercises and connective tissue massage (CTM) in individuals with Fibromyalgia (FM) on pain, disease impact, functional status, anxiety, quality of life and biopsychosocial status. METHODS: 32 women were randomly divided into two groups as intervention gorup (CTM + Clinical Pilates exercises, n = 15, mean age = 48.80 ± 7.48) and control gorup (Clinical Pilates exercises, n = 17, mean age = 55.64 ± 7.87). The number of painful regions were assessed with Pain Location Inventory (PLI), disease impact with Fibromyalgia Impact Questionnare (FIQ), functional status with Health Assessment Questionnare (HAQ), anxiety with Beck Anxiety Inventory (BAI), quality of life with Short Form-36 (SF-36) and biopsychosocial status with Biopsychosocial Questionnaire (BETY-BQ) were evaluated. All evaluations were made before and after treatment. Both treatments were applied 3 times a week for 6 weeks. RESULTS: When the pre-treatment and post-treatment results are analyzed; significant difference was observed in PLI (p = 0.007; effect size 1.273), FIQ (p = 0.004; effect size 0.987), SF-36 physical component (p = 0.025; effect size -0.496) and mental component (p = 0.017; effect size -0.761) in the intervention group while the significant difference was observed in FIQ (p = 0.001; effect size 1.096) and BAI (p = 0.043; effect size 0.392), SF-36 physical component (p = 0.008; effect size -0.507) and mental component (p = 0.024; effect size -0.507) in the control group. When the delta values of the groups are compared, the difference was determined only in the PLI (p = 0.023) in favor of the intervention group. CONCLUSIONS: CTM can be effective in reducing the number of painful areas in addition to the positive effects of clinical Pilates exercises in women with FM.

Effectiveness of manual lymphatic drainage in women with fibromyalgia: A pilot study.

BACKGROUND: Currently there is no treatment capable of significantly alleviating all the symptoms of fibromyalgia (FM), even though it is a complex syndrome with a high prevalence in the population. DESIGN: Experimental study using a single-blind, randomised, clinical trial. OBJECTIVE: To analyse the efficacy of manual lymphatic drainage (MLD) as an alternative to traditional treatment of fibromyalgia (FM) in women. METHODS: This was an experimental study using a single-blind, randomised, clinical trial of 20 women between 30 and 55 years old with FM. Patients were divided into an experimental group (n = 10) and a control group (n = 10). During the study, 3 measurements of pain (visual analogue scale and algometry), FM impact (Fibromyalgia Impact Questionnaire), sleep quality (Index Pittsburgh), anxiety and depression (Hospital Anxiety and Depression Scale) were recorded. Treatment of the experimental group consisted of 2 weekly MLD sessions for 6 weeks. RESULTS: The effect of the interaction of MLD showed statistically significant results in Right intercostal space (F2,36 = 3.54; p = 0.04; n2p = 0.16). The sleep quality was significantly better favour of the treatment (F2,36 = 4.16; p = 0.01; n2p = 0.20). CONCLUSIONS: MLD therapy demonstrated effects in the experimental group in contrast to the control group across the intervention period concerning the right intercostal space and sleep-related factors. However, MLD did not result in observable alterations in pain perception.

Hyperbaric oxygen therapy vs. pharmacological intervention in adults with fibromyalgia related to childhood sexual abuse: prospective, randomized clinical trial.

Fibromyalgia syndrome (FMS) is a chronic pain syndrome characterized by disruptions in pain processing within the central nervous system. It exhibits a high prevalence among patients with a history of traumatic experiences, notably childhood sexual abuse (CSA). This study compared the efficacy of hyperbaric oxygen therapy (HBOT) to the current pharmacological standard of care for individuals suffering from CSA-related FMS. Forty-eight participants diagnosed with FMS and a history of CSA were randomly assigned to either the HBOT group (60 sessions of 100% oxygen at 2 ATA for 90 min, with air breaks every 5 min) or the medication (MED) group (FDA-approved medications, Pregabalin and Duloxetine). The primary endpoint was the Fibromyalgia impact questionnaire (FIQ) score, while secondary endpoints encompassed emotional status and daily functioning questionnaires, as well as pain thresholds and conditioned pain modulation tests. Brain activity was evaluated through single photon emission computed tomography (SPECT). Results revealed a significant group-by-time interaction for the FIQ score favoring HBOT over MED (p < 0.001), with a large effect size (Cohen's d = - 1.27). Similar findings were observed in emotional symptoms and functional measures. SPECT imaging demonstrated an increase in activity in pre-frontal and temporal brain areas, which correlated with symptoms improvement. In conclusion, HBOT exhibited superior benefits over medications in terms of physical, functional, and emotional improvements among FMS patients with a history of CSA. This associated with increased activity in pre-frontal and temporal brain areas, highlighting the neuroplasticity effect of HBOT.

A Cross-Sectional Survey Study of Cannabis Use for Fibromyalgia Symptom Management.

OBJECTIVE: To assess the use of cannabis as a symptom management strategy for patients with fibromyalgia. PATIENTS AND METHODS: An electronic, cross-sectional survey was conducted among patients diagnosed with fibromyalgia and treated in Integrative Medicine & Health at Mayo Clinic, Rochester, Minnesota. The survey was constructed with the Symptom Management Theory tool and was sent anonymously via web-based software to patients with a diagnosis of fibromyalgia. RESULTS: Of 5234 patients with fibromyalgia sent the online survey, 1336 (25.5%) responded and met the inclusion criteria. Survey respondents had a median age of 48 (Q1-Q3: 37.5-58.0) years, and most identified as female. Nearly half of respondents (49.5%, n=661) reported cannabis use since their fibromyalgia diagnosis. The most common symptoms for which respondents reported using cannabis were pain (98.9%, n=654); fatigue (96.2%; n=636); stress, anxiety, or depression (93.9%; n=621); and insomnia (93.6%; n=619). Improvement in pain symptoms with cannabis use was reported by 82.0% (n=536). Most cannabis-using respondents reported that cannabis also improved symptoms of stress, anxiety, and depression and of insomnia. CONCLUSION: Considering that cannabis is a popular choice among patients for managing fibromyalgia symptoms, clinicians should have adequate knowledge of cannabis when discussing therapeutic options for fibromyalgia with their patients.

Online Questionnaire with Fibromyalgia Patients Shows Negative Correlations between Disease Severity and Adherence to Mediterranean Diet.

Fibromyalgia (FM) is a multidimensional disorder in which intense chronic pain is accompanied by a variety of psychophysical symptoms that impose a burden on the patients' quality of life. Despite the efforts and the recent advancement in research, FM pathogenesis and effective treatment remain unknown. Recently, the possible role of dietary patterns and/or components has been gaining attention. The current study aimed to investigate a potential correlation between adherence to the Mediterranean diet (MedDiet) and FM severity in a sample of Italian FM patients. An online survey was designed, composed of customized questions and validated questionnaires with the aim of investigating the intensity and type of pain, the presence of other psychophysical symptoms, the overall impact of FM, general food and lifestyle habits, and adherence to the MedDiet. The collected responses were analyzed for descriptive statistics, linear regression, and propensity score analyses. The results show that, despite considerable use of pharmaceuticals and supplements, FM participants suffered from a high-severity grade disease. However, those with good adherence to the MedDiet experienced a lower pain intensity and overall FM impact. A propensity score analysis indicates a positive influence of the MedDiet against FM severity, thus unveiling the need for well-designed intervention studies to evaluate the therapeutic potential of different dietary patterns.

Healthcare experiences of fibromyalgia patients and their associations with satisfaction and pain relief. A patient survey.

OBJECTIVES: The etiology of fibromyalgia (FM) is disputed, and there is no established cure. Quantitative data on how this may affect patients' healthcare experiences are scarce. The present study aims to investigate FM patients' pain-related healthcare experiences and explore factors associated with high satisfaction and pain relief. METHODS: An anonymous, online, and patient-administered survey was developed and distributed to members of the Norwegian Fibromyalgia Association. It addressed their pain-related healthcare experiences from both primary and specialist care. Odds ratios for healthcare satisfaction and pain relief were estimated by binary logistic regression. Directed acyclic graphs guided the multivariable analyses. RESULTS: The patients (n = 1,626, mean age: 51 years) were primarily women (95%) with a 21.8-year mean pain duration and 12.7 years in pain before diagnosis. One-third did not understand why they had pain, and 56.6% did not know how to get better. More than half had not received satisfactory information on their pain cause from a physician, and guidance on how to improve was reported below medium. Patients regretted a lack of medical specialized competence on muscle pain and reported many unmet needs, including regular follow-up and pain assessment. Physician-mediated pain relief was low, and guideline adherence was deficient. Only 14.8% were satisfied with non-physician health providers evaluating and treating their pain, and 21.5% were satisfied (46.9% dissatisfied) with their global pain-related healthcare. Patients' knowledge of their condition, physicians' pain competence and provision of information and guidance, agreement in explanations and advice, and the absence of unmet needs significantly increased the odds of both healthcare satisfaction and pain relief. CONCLUSIONS: Our survey describes deficiencies in FM patients' pain-related healthcare and suggests areas for improvement to increase healthcare satisfaction and pain relief.

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.

Effects of Prolonged Medical Fasting during an Inpatient, Multimodal, Nature-Based Treatment on Pain, Physical Function, and Psychometric Parameters in Patients with Fibromyalgia: An Observational Study.

Fibromyalgia syndrome (FMS) is a common chronic pain disorder and often occurs as a concomitant disease in rheumatological diseases. Managing FMS takes a complex approach and often involves various non-pharmacological therapies. Fasting interventions have not been in the focus of research until recently, but preliminary data have shown effects on short- and medium-term pain as well as on physical and psychosomatic outcomes in different chronic pain disorders. This single-arm observational study investigated the effects of prolonged fasting (3-12 days, <600 kcal/d) embedded in a multimodal treatment setting on inpatients with FMS. Patients who were treated at the Department of Internal Medicine and Nature-Based Therapies of the Immanuel Hospital Berlin, Germany, between 02/2018 and 12/2020 answered questionnaires at hospital admission (V0) and discharge (V1), and then again three (V2), six (V3), and 12 (V4) months later. Selected routine blood and anthropometric parameters were also assessed during the inpatient stay. A total of 176 patients with FMS were included in the study. The Fibromyalgia Impact Questionnaire (FIQ) total score dropped by 13.7 ± 13.9 (p < 0.001) by V1, suggesting an improvement in subjective disease impact. Pain (NRS: reduction by 1.1 ± 2.5 in V1, p < 0.001) and quality of life (WHO-5: +4.9 ± 12.3 in V1, p < 0.001) improved, with a sustainable effect across follow-up visits. In contrast, mindfulness (MAAS: +0.3 ± 0.7 in V1, p < 0.001), anxiety (HADS-A: reduction by 2.9 ± 3.5 in V1, p < 0.0001), and depression (HADS-D: reduction by 2.7 ± 3.0 in V1, p < 0.0001) improved during inpatient treatment, without longer-lasting effects thereafter. During the study period, no serious adverse events were reported. The results suggest that patients with FMS can profit from a prolonged therapeutic fasting intervention integrated into a complex multimodal inpatient treatment in terms of quality of life, pain, and disease-specific functional parameters.

Comparative Analysis of Psychophysiological Responses in Fibromyalgia Patients: Evaluating Neuromodulation Alone, Neuromodulation Combined with Virtual Reality, and Exercise Interventions.

BACKGROUND AND OBJECTIVES: Fibromyalgia, a chronic condition, manifests as widespread musculoskeletal pain, fatigue, sleep disturbances, autonomic and cognitive dysfunction, hypersensitivity to stimuli, and various somatic and psychiatric symptoms. This study, a controlled and randomized experiment, aimed to evaluate and compare the immediate effects of different treatments on fibromyalgia patients. MATERIALS AND METHODS: The treatments included the EXOPULSE Mollii suit, a combination of the EXOPULSE Mollii suit with a virtual reality (VR) protocol, and a physical exercise regimen. A cohort of 89 female fibromyalgia patients was randomly assigned to one of four groups: Control (n = 20), Suit only (n = 22), Suit combined with VR (n = 21), and Exercise (n = 26). RESULTS: This study found notable differences across the groups in several key parameters. In the Control group, significant changes were observed in Forced Expiratory Volume (FEV 1/FEV 6), the Numeric Rating Scale (NRS) for pain, Pressure Pain Threshold (PPT) at the epicondyle, cortical arousal levels, the 10 m up-and-go test, and in all measured variables related to temperature and muscle oxygenation. For the group using the suit alone, there were significant differences noted in the NRS, the chair stand test, palm temperature, and all muscle oxygenation parameters. The Suit + VR group showed significant changes in the NRS, PPT at the knee, handgrip strength test, the 10 m up-and-go test, one-leg balance test with the right leg, muscle oxygen saturation (SmO2), deoxygenated hemoglobin (HHb), and oxygenated hemoglobin (O2Hb). Finally, the Exercise group exhibited significant differences in FEV 1/FEV 6, chest perimeter difference, NRS, PPT at both the epicondyle and knee, cortical arousal, the chair stand test, the 10-m up-and-go test, and in SmO2, HHb, and O2Hb levels. CONCLUSIONS: combining neuromodulation with VR and targeted exercise regimens can effectively alleviate fibromyalgia symptoms, offering promising avenues for non-pharmacological management.

Efficacy of aquatic vs land-based therapy for pain management in women with fibromyalgia: a randomised controlled trial.

OBJECTIVE: To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia. DESIGN: Single-blind, randomised controlled, equivalence trial. SETTING: Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain. PARTICIPANTS: Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20). INTERVENTIONS: Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist. OUTCOME: The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated. RESULTS: The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up. CONCLUSIONS: The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia. CLINICAL TRIALS REGISTRATION NUMBER: ClinicalTrials.gov NCT02695875 CONTRIBUTION OF THE PAPER.

Efficacy and safety of transcranial direct current stimulation in the treatment of fibromyalgia: A systematic review and meta-analysis.

OBJECTIVES: To update a systematic review of the efficacy and safety of transcranial direct current stimulation (tDCS) for analgesia, for antidepressant effects, and to reduce the impact of fibromyalgia (FM), looking for optimal areas of stimulation. METHODS: We searched five databases to identify randomized controlled trials comparing active and sham tDCS for FM. The primary outcome was pain intensity, and secondary outcome measures included FM Impact Questionnaire (FIQ) and depression score. Meta-analysis was conducted using standardized mean difference (SMD). Subgroup analysis was performed to determine the effects of different regional stimulation, over the primary motor cortex (M1), dorsolateral prefrontal cortex (DLPFC), opercular-insular cortex (OIC), and occipital nerve (ON) regions. We analyzed the minimal clinically important difference (MCID) by the value of the mean difference (MD) for an 11-point scale for pain, the Beck Depressive Inventory-II (BDI-II), and the Fibromyalgia Impact Questionnaire (FIQ) score. We described the certainty of the evidence (COE) using the tool GRADE profile. RESULTS: Twenty studies were included in the analysis. Active tDCS had a positive effect on pain (SMD= -1.04; 95 % CI -1.38 to -0.69), depression (SMD= -0.46; 95 % CI -0.64 to -0.29), FIQ (SMD= -0.73; 95 % CI -1.09 to -0.36), COE is moderate. Only group M1 (SD=-1.57) and DLPFC (SD=-1.44) could achieve MCID for analgesia; For BDI-II, only group DLPFC (SD=-5.36) could achieve an MCID change. Adverse events were mild. CONCLUSION: tDCS is a safe intervention that relieves pain intensity, reduces depression, and reduces the impact of FM on life. Achieving an MCID is related to the stimulation site and the target symptom.

Impact of multiple-session home-based transcranial direct current stimulation (M-HB-tDCS) on eating behavior in fibromyalgia: A factorial randomized clinical trial.

BACKGROUND: Multiple-session home-based self-applied transcranial direct current stimulation (M-HB-self-applied-tDCS) has previously been found to effectively reduce chronic pain and enhance cognitive function. However, the effectiveness of this method for disordered eating behavior still needs to be studied. OBJECTIVE: This study aimed to assess whether 20 sessions of M-HB-self-applied-tDCS, administered over four weeks to either the left dorsolateral prefrontal cortex (L-DLPFC) or primary motor cortex (M1), could improve various aspects of eating behavior, anthropometric measures, and adherence. METHODS: We randomly assigned 102 fibromyalgia patients between the ages of 30 and 65 to one of four tDCS groups: L-DLPFC (anodal-(a)-tDCS, n = 34; sham-(s)-tDCS, n = 17) or M1 (a-tDCS, n = 34; s-tDCS, n = 17). Patients self-administered 20-min tDCS sessions daily with 2 mA under remote supervision following in-person training. RESULTS: Generalized linear models revealed significant effects of M-HB-self-applied-tDCS compared to s-tDCS on uncontrolled eating (UE) (Wald χ2 = 5.62; df = 1; P = 0.018; effect size, ES = 0.55), and food craving (Wald χ2 = 5.62; df = 1; P = 0.018; ES = 0.57). Regarding fibromyalgia symptoms, we found a differentiated impact of a-tDCS on M1 compared to DLPFC in reducing food cravings. Additionally, M-HB-a-tDCS significantly reduced emotional eating and waist size. In contrast, M1 stimulation was more effective in improving fibromyalgia symptoms. The global adherence rate was high, at 88.94%. CONCLUSION: These findings demonstrate that M-HB-self-applied-tDCS is a suitable approach for reducing uncontrolled and emotional eating, with greater efficacy in L-DLPFC. Furthermore, these results revealed the influence of fibromyalgia symptoms on M-HB-self-applied-tDCS's, with M1 being particularly effective in mitigating food cravings and reducing fibromyalgia symptoms.

Health personnel perception about central sensitivity syndrome-fibromyalgia patients.

BACKGROUND AND OBJECTIVES: Fibromyalgia is characterized by musculoskeletal pain and asthenia of chronic course. Fibromyalgia patients are often a challenge for the health care community as a whole. Existing studies are often limited to the opinion of rheumatologists or family physicians. With this study we seek to know what are the actions, perceptions and knowledge of health professionals as a whole when caring for patients with this disease. MATERIALS AND METHODS: Descriptive cross-sectional study, by means of a self-administered and anonymous survey. Distributed mainly in hospital wards and primary care centers. Statistical analysis of the variables collected was performed (p < 0.05). RESULTS: 200 surveys were collected, most of them physicians 63.5% (n = 127) or nurses 25.5% (n = 51). 71% of physicians reported using the WHO analgesic scale. 53% (n = 59) use NSAIDs or Paracetamol. Antidepressants are the third drug of choice. Most believe that the referral specialists should be rheumatologists or primary care physicians, a similar percentage, that management should be multidisciplinary. 52% feel discouraged or annoyed when dealing with these patients. Physicians have more negative connotations and believe that the care that the patient receives is mostly influenced by the diagnosis of fibromyalgia, compared to nurses and other professionals. CONCLUSIONS: Our study shows that the lack of knowledge and therapeutic tools generates, to a large extent, frustration and discomfort in health personnel. It is important to develop new approaches to this entity.

Patient-journey of fibromyalgia patients: A scoping review.

BACKGROUND: Fibromyalgia (FM) is a chronic disease characterized by widespread pain. Although much is known about this disease, research has focused on diagnosis and treatment, leaving aside factors related to patient's experience and the relationship with healthcare system. OBJECTIVES: The aim was to analyze the available evidence on the experience of FM patients from the first symptoms to diagnosis, treatment, and follow-up. METHODS: A scoping review was carried out. Medline and the Cochrane Library were searched for original studies or reviews dealing with FM and focusing on "patient journey". Results were organized using a deductive classification of themes. RESULTS: Fifty-four articles were included in the qualitative synthesis. Five themes were identified: the patient journey, the challenge for the health systems, a complex doctor-patient relationship, the importance of the diagnosis, and the difficulty of standardizing the treatment. CONCLUSIONS: This scoping review confirms the negative impact of FM on the patient, their social environment, and health systems. It is necessary to minimize the difficulties encountered throughout the diagnosis and follow-up of patients with FM.

Efficacy of neuromodulation on the treatment of fibromyalgia: A network meta-analysis.

OBJECTIVE: Several types of neuromodulation have been investigated for the treatment of fibromyalgia, but they show varied efficacy on pain, functioning, comorbid depression and comorbid anxiety. Whether some types of neuromodulation or some factors are associated with a better response also awaits clarification. METHODS: We conducted a systematic review and network meta-analysis of randomized controlled trials to evaluate the efficacy of neuromodulation in patients with fibromyalgia. We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and PsycINFO before March 2022. We employed a frequentist random-effects network meta-analysis. RESULTS: Forty trials involving 1541 participants were included. Compared with sham control interventions, several types of transcranial direct current stimulation (tDCS), transcranial random noise stimulation (tRNS), and high-frequency repetitive transcranial magnetic stimulation (rTMS) were associated with significant reduction of pain, depression, anxiety, and improvement in functioning. Many significantly effective treatment options involve stimulation of the primary motor cortex or dorsolateral prefrontal cortex. CONCLUSION: We concluded that several types of rTMS, tDCS and tRNS may have the potential to be applied for clinical purposes.

Relationship of migraine and other forms of chronic pain.

The disability of migraine, a highly prevalent condition, is worsened by a second comorbid chronic pain condition. There is evidence of a relationship between migraine and several visceral pain conditions including irritable bowel syndrome, endometriosis, and dysmenorrhoea, as well as nonvisceral conditions including temporomandibular dysfunction, fibromyalgia, and lower back pain. While the mechanisms linking these conditions are inadequately surmised, a two-way relationship between migraine and these comorbidities likely exists. The progression and chronification of migraine is associated with peripheral and central sensitization, which may predispose to other conditions. Conversely, aspects of the mechanism of each comorbid condition may promote further migraine attacks. This chapter introduces each comorbidity, briefly summarizes the existing evidence, and discusses implications for treatment.

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.

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.
