Feldenkrais awareness though movement intervention for fibromyalgia syndrome: A proof-of-concept study.

INTRODUCTION: The Feldenkrais Method® is a form of awareness through movement (ATM) aimed at improving spatial and kinesthetic awareness through verbally guided movements, in order to learn more effective actions. METHOD: The present study, a proof-of-concept, observational, non-controlled prospective study, aims at exploring the effectiveness of ATM for fibromyalgia syndrome (FM), measuring the effect by means of multi-dimensional questionnaires, administered at baseline and after 4 months of ATM activity. RESULTS: One hundred twenty-eight FM patients (mean age 54 years old, 2% males) participated in the study. A statistically significant improvement was found in FM-specific measures (Polysymptomatic Distress Scale, PDS) (p = 0.003) and the Pain Catastrophization Scale (PCS) (p = 0.020); coherently, the Revised Fibromyalgia Impact Questionnaire (FIQR) showed a trend in improvement after the intervention, although this improvement was not statistically significant. The logistic regression analysis found a correlation between PDS, fatigue and anxiety measures; PCS, years from diagnosis and anxiety. CONCLUSION: ATM could improve FM-specific measures and pain-related catastrophizing. Further studies are needed to identify FM subgroups in order to find personalized targets that can be used to guide treatments.

Can Electroacupuncture Be Useful in Opioid-Induced Hyperalgesia? A Case Report.

Opioid-induced hyperalgesia (OIH) is characterized by a paradoxical increase in pain sensitivity following opioid exposure. Although animal models indicate that electroacupuncture (EA) is effective against pain sensitization, there are no reports of its clinical application in OIH treatment. This case report involves an adult patient with osteomalacia complicated by multiple vertebral fragility fractures. The patient developed OIH following the use of oxycodone to treat severe disabling lower back pain that was refractory to nonsteroidal anti-inflammatory drugs. After hospitalization and treatment with low EA-frequency (2-10 Hz) sessions, the patient exhibited significant pain reduction and functional recovery after the first session, which was accompanied by steady progressive improvement as the treatment continued. This case report illustrates the clinical efficacy of EA in OIH treatment and indicates that EA, which has multiple modes of action on the neurobiology of chronic pain, has potential applications in the management of complex and difficult-to-manage conditions, such as OIH.

Palmitoylethanolamide and acetyl-L-carnitine act synergistically with duloxetine and pregabalin in fibromyalgia: results of a randomised controlled study.

OBJECTIVES: Fibromyalgia (FM) is characterised by a form of debilitating pain that is unresponsive to standard analgesics. The aim of this study was to evaluate the efficacy of supplementing ongoing pregabalin (PGB) and duloxetine (DLX) treatment with palmitoylethanolamide (PEA) and acetyl-L-carnitine (ALC) for 24 weeks in FM patients. METHODS: After undergoing three months of stable treatment with DLX+PGB, FM patients were randomised to continue the same treatment (Group 1) or to add PEA 600 mg b.i.d + ALC 500 mg b.i.d. (Group 2) for a further 12 weeks. Every two weeks throughout the study, cumulative disease severity was estimated using the Widespread Pain Index (WPI) as the primary outcome measure; the secondary outcomes were the fortnightly scores of the patient-completed revised Fibromyalgia Impact Questionnaire (FIQR) and the modified Fibromyalgia Assessment Status (FASmod) questionnaire. All three measures were expressed as time-integrated area under the curve (AUC) values. RESULTS: One hundred and thirty (91.5%) of the initial 142 FM patients completed the study: 68 patients in Group 1 and 62 in Group 2. Twenty-four weeks after randomisation, the Group 2 patients showed additional significant improvements in all three outcome measures. Although there was some fluctuation in both groups during the study period, the AUC values of the WPI scores steadily decreased in Group 2 (p=0.048), which also showed better outcomes in terms of the AUC values of the FIQR (p=0.033) and FASmod scores (p=0.017). CONCLUSIONS: This is the first randomised controlled study demonstrating the effectiveness of the adding on therapy of PEA+ALC to DLX+PGB in FM patients.

Fibromyalgia: one year in review 2023.

Fibromyalgia (FM) is a chronic syndrome characterised by widespread pain that affects millions of people worldwide. This article discusses various aspects of FM described in scientific papers published in 2022 and indexed in the PubMed database, including the most recent diagnostic acquisitions (especially in relation to the juvenile form of FM), risk factors, co-morbidities and objective measures. Emphasis is placed on the importance of identifying FM early and improving diagnostic methods (e.g. physical measurements, including walking test performance, hand grip force, and autonomic tests). The article also considers hypotheses concerning the pathophysiology of FM, including the role of inflammation, gut dysbiosis, and neuroinflammation, and possible treatment options, including medications such as antioxidants and kinin antagonists, neurostimulation, and mind-body interventions. Although ketamine, vitamin D, and hormone therapy have shown promise in reducing FM symptoms, further research is needed to optimise their use. Neurostimulation techniques, such as transcutaneous electrical nerve stimulation, transcranial direct-current stimulation and transcranial magnetic stimulation, have been investigated in terms of their efficacy in reducing pain and improving the quality of life. Finally, the role of nutrition is discussed as study findings suggest that weight control, modified high-antioxidant diets, and nutritional supplementation can help to alleviate the symptoms of FM.

Predicting acupuncture efficacy in fibromyalgia: results of a pragmatic open-label study.

OBJECTIVES: To identify the predictive factors of treatment response to acupuncture in patients with fibromyalgia (FM). METHODS: Patients with FM refractory to standard drug therapy underwent eight weekly acupuncture sessions. Significant improvement, defined as a reduction of at least 30% of the revised Fibromyalgia Impact Questionnaire (FIQR), was assessed at the end of the eight weeks (T1) of treatment and three months after the end of treatment (T2). Univariate analysis was conducted to identify predictors of significant improvement at T1 and T2. Variables that resulted to be significantly associated with clinical improvement at univariate analysis were included in multivariate models. RESULTS: Analyses were conducted on 77 patients (9 males, 11.7%). At T1, significant improvement in FIQR was recorded in 44.2% of patients. At T2, persistent significant improvement was recorded in 20.8% of patients. In the multivariate analysis, predictive variables of treatment failure were tender point count (TPC) (odds ratio [OR] =0.49, 95% confidence interval [95% CI]: 0.28-0.86, p=0.01) and pain magnification (OR=0.68, 95% CI: 0.47-0.99, p=0.04) assessed with the Pain Catastrophising Scale, at T1. At T2, the only predictive variable of treatment failure was concomitant duloxetine use (OR=0.21, 95% CI: 0.05-0.95, p=0.04). CONCLUSIONS: High TPC and a tendency for pain magnification predict immediate treatment failure, while duloxetine therapy predicts it three months after completion of the acupuncture course. The identification of clinical characteristics of unfavourable response to acupuncture could help to implement a cost-effective prevention of treatment failure in FM.

Pain Changes Induced by Acupuncture in Single Body Areas in Fibromyalgia Syndrome: Results from an Open-Label Pragmatic Study.

To date, there is considerable evidence of the effectiveness of acupuncture in fibromyalgia syndrome (FM). However, it is not known in which body areas acupuncture is more effective. The objective of this study was to assess the improvements of pain induced by acupuncture in single body areas in patients with FM. In this open-label pragmatic study, FM patients in a state of high disease severity were consecutively enrolled and treated with a course of 8 weekly sessions of manual acupuncture. Patients were assessed with the Self-Administered Pain Scale (SAPS) of the Fibromyalgia Assessment Status at baseline and at the end of eight acupuncture sessions. Acupuncture sessions were all conducted with the same acupuncture formula (LV3, SP6, ST36, LI4, CV6, CV12, Ex-HN-3, and GV20) in each session and in each patient. Ninety-six FM patients completed the course of treatment. All the 16 body areas assessed by SAPS showed improvement in pain. A statistically significant improvement was achieved in 12 of the 16 body areas investigated, with the best results in abdomen and forearms (p = 0.001), while the worst results were registered for neck (p = 0.058), chest (p = 0.059), left buttock (p = 0.065), and right thigh (p = 0.052). The treatment has also shown significant effectiveness in improving fatigue and sleep quality (p < 0.0001). Acupuncture has a beneficial effect on pain in all body areas in FM patients with high disease severity, with the greatest effects in the abdominal region and in the forearms, allowing a personalization of the treatment.

Acupuncture for Fibromyalgia: An Open-Label Pragmatic Study on Effects on Disease Severity, Neuropathic Pain Features, and Pain Catastrophizing.

The treatment of fibromyalgia syndrome (FMS) is still far from being optimally coded, and pharmacological strategies are often unsatisfactory. Acupuncture plays a role among nonpharmacological intervention approaches; however, there is still no clarity as to when to integrate it into therapy. The objective of this study is to explore the role of acupuncture, in terms of efficacy on main disease severity measures and pain features, in patients with nonresponsive disease, defining nonresponsive FMS characterized by a revised Fibromyalgia Impact Questionnaire (FIQ-R) ≥39 and a Patient Health Questionnaire 15-item (PHQ15) ≥5 despite optimal drug therapy. Patients were treated with weekly sessions, for a total of eight acupuncture sessions. At the baseline and at the end of the treatment cycle, a comprehensive clinical evaluation was carried out to evaluate improvements in terms of disease severity and impact on neuropathic pain features (measured with the painDETECT questionnaire (PDQ)) and pain catastrophizing (measured with the Pain Catastrophizing Scale (PCS)). At the end of the eight-week treatment, patients experienced a significant improvement in all evaluated parameters (for FIQ-R, PDQ, and PHQ15 p < 0.0001, for PCS p=0.001). Of particular note is the effectiveness on manifestations that are difficult to treat such as neuropathic pain features and on negative psychological perceptions such as pain catastrophizing. It can be stated that acupuncture can be proposed also in phases of high severity of disease. Intervention with multimodal strategies, including acupuncture, could be of great benefit to patients.

Adding medical cannabis to standard analgesic treatment for fibromyalgia: a prospective observational study.

OBJECTIVES: To assess any clinical improvement attributable to the addition of medical cannabis treatment (MCT) to the stable (>3 months) standard analgesic treatment of fibromyalgia (FM) patients, the retention rate and any changes in the concomitant analgesic treatment over a period of six months. METHODS: The study involved 102 consecutive FM patients with VAS scores ≥4 despite standard analgesic treatment. Patients were prescribed two oil-diluted cannabis extracts: Bedrocan (22% THC, <1% CBD), and Bediol (6.3% THC, 8% CBD). FM severity was periodically assessed using Fibromyalgia Impact Questionnaire (FIQR), Fibromyalgia Assessment Scale (FAS), FACIT-Fatigue score, Pittsburgh Sleep Quality Index (PSQI), and Zung Depression and Anxiety Scales. During the study, patients were allowed to reduce or stop their concomitant analgesic therapy. RESULTS: The 6-month retention rate was 64%. A significant improvement in the PSQI and FIQR was observed in respectively 44% and 33% of patients. 50% showed a moderate improvement in the anxiety and depression scales. Multiple regression analysis showed a correlation between the body mass index (BMI) and FIQR improvement (p=0.017). Concomitant analgesic treatment was reduced or suspended in 47% of the patients. One-third experienced mild adverse events, which did not cause any significant treatment modifications. CONCLUSIONS: This observational study shows that adjunctive MCT offers a possible clinical advantage in FM patients, especially in those with sleep dysfunctions. The clinical improvement inversely correlated with BMI. The retention rate and changes in concomitant analgesic therapy reflect MCT efficacy of the improved quality of life of patients. Further studies are needed to confirm these data, identify MCT-responsive sub-groups of FM patients, and establish the most appropriate posology and duration of the therapy.

Medical cannabis and cannabinoids in rheumatology: where are we now?

Introduction: Clinicians involved in pain management can finally include cannabis or cannabis-related products in their therapeutic armamentarium as a growing number of countries have approved them for pain relief. Despite the several benefits attributed to analgesic, anti-inflammatory and immunomodulatory properties of cannabinoids, there are still significant areas of uncertainty concerning their use in many fields of medicine. The biosynthesis and inactivation of cannabinoids are regulated by a complex signaling system of cannabinoid receptors, endocannabinoids (the endogenous ligands of cannabinoid receptors) and enzymes, with a variety of interactions with neuroendocrinological and immunological systems. Areas covered: A review of studies carried out during clinical development of cannabis and cannabis medical products in systemic rheumatic diseases was performed, highlighting the aspects that we believe to be relevant to clinical practice. Expert opinion: The growing public opinion, pushing toward the legalization of the use of cannabis in chronic pain and various rheumatological conditions, makes it necessary to have educational programs that modify the concerns and widespread preconceptions related to this topic in the medical community by increasing confidence. More extensive basic and clinical research on the mechanisms and clinical utility of cannabis and derivatives in various diseases and their long-term side effects is necessary.

Body mass index as a driver of selection of biologic therapy in rheumatoid arthritis. Results from the US-CLARA study.

PURPOSE: Body mass index (BMI) demonstrated to influence the clinical response to different drugs in rheumatoid arthritis (RA). The aim of this study was to investigate the role of BMI in the achievement of remission in active RA patients starting the treatment with abatacept. METHODS: Data regarding 130 RA patients enrolled in the UltraSound-CLinical ARthritis Activity (US-CLARA) study were retrospectively analyzed. Patients were assessed at baseline (when starting abatacept treatment) and at 3- and 6-months. An extensive clinimetric evaluation, including a new ultrasound (US)/clinical composite disease activity index, termed US-CLARA, was performed at every timepoints. Outcome of interest of the study was the impact of BMI on the achievement of the Disease Activity Score 28-joints erythrocyte sedimentation rate (DAS28-ESR) or the ACR/EULAR Boolean remission criteria at 6 month. RESULTS: At 6-month 26 out of 130 patients were defined as responders to abatacept. Comparing the baseline characteristics of responders to non-responders, US-CLARA showed a statistically significant difference between the two groups. The logistic regression analysis showed that the two indipendent variables, predictive of treatment response (keeping the DAS28-ESR and/or Boolean remission criteria as dependent variable), were the self-tender joint count assessment (p = 0.0412) and the ultrasound score (p = 0.0211). No other baseline variable, notably BMI, was associated to 6-month abatacept response. CONCLUSIONS: BMI does not influence the abatacept response in RA patients with active disease. During abatacept treatment, the clinical response can be achieved despite a condition of overweight or obesity.

Hyperbaric oxygen treatment of fibromyalgia: a prospective observational clinical study.

OBJECTIVES: Fibromyalgia (FM) is a syndrome of unknown aetiology that is characterised by widespread musculoskeletal pain, fatigue and disordered sleep, and often associated with neuropsychiatric and cognitive symptoms. Current treatment options are only partially effective, but hyperbaric oxygen therapy (HBOT) seems to be capable of relieving some of the symptoms. The aim of this study was to evaluate the efficacy and safety of HBOT after fewer sessions than generally used, chosen on the basis of pre-clinical and clinical data showing its rapid and sustained antinociceptive effect. METHODS: Patients with FM underwent HBOT (100% oxygen at 2.5 ata with air breaks) administered on three days per week for a total of twenty 90-minute sessions. Pain, fatigue, the quality of sleep, symptoms of anxiety and depression, and the patients' health-related quality of life were prospectively assessed before and after ten and twenty sessions. RESULTS: Twenty-eight of the 32 study patients completed the 20 HBOT sessions. Pain scores and the symptoms of anxiety (but not those of depression) significantly improved after both 10 and 20 sessions, whereas fatigue and FM symptom severity scores significantly improved only after 20 sessions. There was no significant change in the quality of sleep. The adverse effects were limited. CONCLUSIONS: These findings support the view that HBOT is an effective, rapid and safe means of treating various symptoms of FM.

Neuromuscular efficiency in fibromyalgia is improved by hyperbaric oxygen therapy: looking inside muscles by means of surface electromyography.

OBJECTIVES: Neuromuscular efficiency (NME) is impaired in fibromyalgia (FM). Hyperbaric oxygen therapy (HBOT) is a medical treatment using 100% of oxygen through an oxygen mask. HBOT in FM induces changes in cortical excitability and a secondary reduction in pain and muscle fatigue. However, there are still no direct data indicating changes in muscle fatigue. The aim of this study was to assess whether the reduction in muscle fatigue so far attributed to a central effect of HBOT can be directly detected by means of non-invasive sEMG as a change in NME. METHODS: The study was an observational longitudinal study on changes in NME induced by 20 sessions of HBOT at 2.4 atmosphere, in 22 patients with FM (3M; 19F) (age 49.8±9.5; height 164.7±7.5; weight 63.8±12.7). sEMG was recorded in single differential configuration from the biceps brachii muscle during the 30-second fatiguing contractions using linear arrays of eight adhesive electrodes. RESULTS: Evaluations made before and immediately after the first session showed that maximal strength did not change (T0 49±20 N, T1 49±19 N, p=0.792), thus suggesting that HBOT did not induce muscle fatigue or potentiation. After 20 sessions of HBOT, NME increased from 1.6±1.1 to 2.1±0.8 (p=0.050), whereas maximal strength, EMG amplitude and muscle fibre CV did not change. CONCLUSIONS: HBOT did not improve muscle strength or change muscle fibre content, but improved the ability of the central motor command to generate the same effort (MVC) with fewer recruited fibres. Our sEMG findings underlined a modified central mechanism related to fibre type recruitment order, thus suggesting that muscle fatigue is not primarily a muscular problem, as also demonstrated by other authors with different methods.

Adherence to Anti-Tumor Necrosis Factor Therapy Administered Subcutaneously and Associated Factors in Patients With Rheumatoid Arthritis.

BACKGROUND: Adherence to biologic therapy is relatively poorly studied in rheumatoid arthritis (RA) because many of the studies have investigated the drug persistence, which represents only a surrogate of adherence. OBJECTIVES: The aims of this study were to determine the extent of adherence in RA patients with subcutaneously administered anti-tumor necrosis factor methotrexate agents and to identify the risk factors for nonadherence. METHODS: A cohort of RA patients who started a subcutaneous anti-tumor necrosis factor treatment were enrolled. After 12 months of treatment, all patients completed the 4-item Morisky Medication Adherence Scale questionnaire. Associations between beliefs and nonadherence and the influence of demographic, clinical, and radiographic features were assessed using logistic regression model. RESULTS: A total of 209 (80.4%) of the 260 patients were included in the analyses. Forty-three of 209 patients were considered nonadherent to their medication (20.6%) according to the 4-item Morisky Medication Adherence Scale. More than half (53.1%) of patients showed at least 1 form of nonadherent behavior.The logistic model showed that low disease activity (P = 0.003), higher patient-physician discordance ratings (P = 0.012), older age (P = 0.041), and a high number of comorbid conditions (P = 0.011) were significantly associated with increased likelihood of nonadherence. CONCLUSIONS: The overall nonadherence with subcutaneous biologic therapy is relatively high among RA patients and should be taken into account when a patient's response to treatment is unsatisfactory.

Biomarkers of oxidation, inflammation and cartilage degradation in osteoarthritis patients undergoing sulfur-based spa therapies.

OBJECTIVES: To investigate the effects of sulfur-based spa therapies on oxidation, inflammation and cartilage degradation biomarkers in osteoarthritis (OA) patients. DESIGN AND METHODS: Analyses were performed before therapy (T0), after therapy (T1) and 1 month after its suspension (T2), in OA subjects undergoing mud bath treatments in combination (group A) or not (group B) with hydropinotherapy, and compared with those of patients not subjected to spa therapies (group C). RESULTS: No modifications in plasma/serum biomarker concentrations were observed throughout the study in non-treated patients, while a significant reduction in oxidation, inflammation and cartilage degradation parameters was evidenced in patients of group A. Group B presented a favorable biochemical profile at T1 but not at T2. CONCLUSIONS: To ensure the long term preservation of the chondroprotective effects of sulfur-based therapies, standard mud bath treatments should be associated with hydropinotherapy in order to maintain reduced oxidative, inflammatory and degradative stimuli longer.

[Carpal tunnel syndrome treatment]. / La terapia della sindrome del tunnel carpale.

Carpal tunnel syndrome, the most common peripheral neuropathy, results from compression of the median nerve at the wrist, and is a cause of pain, numbness and tingling in the upper extremities and an increasingly recognized cause of work disability. If carpal tunnel syndrome seems likely, conservative management with splinting should be initiated. Moreover, it has suggested that patients reduce activities at home and work that exacerbate symptoms. Pyridoxine and diuretics, since are largely utilised, are no more effective than placebo in relieving the symptoms. Non steroidal anti-inflammatory drugs and orally administered corticosteroids can be effective for short-term management (two to four weeks), but local corticosteroid injection may improve symptoms for a longer period. Injection is especially effective if there is no loss of sensibility or thenar-muscle atrophy and weakness, and if symptoms are intermittent rather than constant. If symptoms are refractory to conservative measures, the option of surgical therapy may be considered.
