Effectiveness of Exercise on Fatigue and Sleep Quality in Fibromyalgia: A Systematic Review and Meta-analysis of Randomized Trials

Effects of photobiomodulation and an aerobic exercise on the level of pain and quality of life in women with fibromyalgia

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.

Effectiveness of craniosacral therapy, Bowen therapy, static touch and standard exercise program on sleep quality in fibromyalgia syndrome: A randomized controlled trial

BACKGROUND

Sleep disturbance is commonly seen in fibromyalgia syndrome (FMS); however, high quality studies involving manual therapies that target FMS-linked poor sleep quality are lacking for the Indian population.

OBJECTIVE

Craniosacral therapy (CST), Bowen therapy and exercises have been found to influence the autonomic nervous system, which plays a crucial role in sleep physiology. Given the paucity of evidence concerning these effects in individuals with FMS, our study tests the effectiveness of CST, Bowen therapy and a standard exercise program against static touch (the manual placebo group) on sleep quality in FMS.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTION

A placebo-controlled randomized trial was conducted on 132 FMS participants with poor sleep at a hospital in Bangalore. The participants were randomly allocated to one of the four study groups, including CST, Bowen therapy, standard exercise program, and a manual placebo control group that received static touch. CST, Bowen therapy and static touch treatments were administered in once-weekly 45-minute sessions for 12 weeks; the standard exercise group received weekly supervised exercises for 6 weeks with home exercises until 12 weeks. After 12 weeks, all study participants performed the standard exercises at home for another 12 weeks.

MAIN OUTCOME MEASURES

Sleep quality, pressure pain threshold (PPT), quality of life and fibromyalgia impact, physical function, fatigue, pain catastrophizing, kinesiophobia, and positive-negative affect were recorded at baseline, and at weeks 12 and 24 of the intervention.

RESULTS

At the end of 12 weeks, the sleep quality improved significantly in the CST group (P = 0.037) and Bowen therapy group (P = 0.023), and the PPT improved significantly in the Bowen therapy group (P = 0.002) and the standard exercise group (P < 0.001), compared to the static touch group. These improvements were maintained at 24 weeks. No between-group differences were observed for other secondary outcomes.

CONCLUSION

CST and Bowen therapy improved sleep quality, and Bowen therapy and standard exercises improved pain threshold in the short term. These improvements were retained within the groups in the long term by adding exercises. CST and Bowen therapy are treatment options to improve sleep and reduce pain in FMS.

Association between fatigue and depressive symptoms in persons with post-COVID-19 condition: a post hoc analysis

OBJECTIVE

Post-COVID-19 Condition (PCC) is a prevalent, persistent and debilitating phenomenon occurring three or more months after resolution of acute COVID-19 infection. Fatigue and depressive symptoms are commonly reported in PCC. We aimed to further characterize PCC by assessing the relationship between fatigue and depressive symptom severity in adults with PCC.

METHODS

A post hoc analysis was conducted on data retrieved from a randomized, double-blinded, placebo-controlled study evaluating vortioxetine for cognitive deficits in persons with PCC. We sought to determine the relationship between baseline fatigue [i.e. Fatigue Severity Scale (FSS) total score] and baseline depressive symptom severity [i.e. 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR-16) total score] in adults with PCC.

RESULTS

The statistical analysis included baseline data from 142 participants. After adjusting for age, sex, education, employment status, history of major depressive disorder (MDD) diagnosis, self-reported physical activity, history of documented acute SARS-CoV-2 infection and body mass index (BMI), baseline FSS was significantly correlated with baseline QIDS-SR-16 (β = 0.825, p = .001).

CONCLUSION

In our sample, baseline measures of fatigue and depressive symptoms are correlated in persons living with PCC. Individuals presenting with PCC and fatigue should be screened for the presence and severity of depressive symptoms. Guideline-concordant care should be prescribed for individuals experiencing clinically significant depressive symptoms. Fatigue and depressive symptom severity scores were not pre-specified as primary objectives of the study. Multiple confounding factors (i.e. disturbance in sleep, anthropometrics and cognitive impairment) were not collected nor adjusted for in the analysis herein.

Renshen Yangrong decoction for secondary malaise and fatigue: network pharmacology and Mendelian randomization study

Background

Renshen Yangrong decoction (RSYRD) has been shown therapeutic effects on secondary malaise and fatigue (SMF). However, to date, its bioactive ingredients and potential targets remain unclear.

Purpose

The purpose of this study is to assess the potential ingredients and targets of RSYRD on SMF through a comprehensive strategy integrating network pharmacology, Mendelian randomization as well as molecular docking verification.

Methods

Search for potential active ingredients and corresponding protein targets of RSYRD on TCMSP and BATMAN-TCM for network pharmacology analysis. Mendelian randomization (MR) was performed to find therapeutic targets for SMF. The eQTLGen Consortium (sample sizes: 31,684) provided data on cis-expression quantitative trait loci (cis-eQTL, exposure). The summary data on SMF (outcome) from genome-wide association studies (GWAS) were gathered from the MRC-IEU Consortium (sample sizes: 463,010). We built a target interaction network between the probable active ingredient targets of RSYRD and the therapeutic targets of SMF. We next used drug prediction and molecular docking to confirm the therapeutic value of the therapeutic targets.

Results

In RSYRD, network pharmacology investigations revealed 193 possible active compounds and 234 associated protein targets. The genetically predicted amounts of 176 proteins were related to SMF risk in the MR analysis. Thirty-seven overlapping targets for RSYRD in treating SMF, among which six (NOS3, GAA, IMPA1, P4HTM, RB1, and SLC16A1) were prioritized with the most convincing evidence. Finally, the 14 active ingredients of RSYRD were identified as potential drug molecules. The strong affinity between active components and putative protein targets was established by molecular docking.

Conclusion

This study revealed several active components and possible RSYRD protein targets for the therapy of SMF and provided novel insights into the feasibility of using Mendelian randomization for causal inference between Chinese medical formula and disease.

The role of pain intensity and depressive symptoms in the relationship between sleep quality and postural control among middle-aged and older adults with Fibromyalgia

OBJECTIVE

Fibromyalgia (FM) is a chronic pain condition often accompanied by sleep problems and depression that are each associated with reduced physical ability including postural control. Research supports a sequential association between pain intensity and depression in FM, and poor sleep quality may play a key role in this relationship. This study aimed to verify a serial pattern of associations among sleep quality, pain intensity, and depressive symptoms and quantify these effects on objective postural control.

DESIGN

Community-residing adults diagnosed with FM (n = 155; Mage = 61.08, SD = 7.70; 93% female; 79% White) were included in this cross-sectional study.

MAIN OUTCOMES

Participants self-rated sleep quality (restorative sleep, sleep waking, and sleep latency), pain intensity, and depressive symptoms, and the Fullerton Advanced Balance (FAB) scale and 8-Foot Up and Go Test (8FUPGT) measured objective postural control.

RESULTS

Findings indicated that the serial association between pain intensity and depressive symptoms fully mediated the relationship between sleep quality and both FAB (95% CI [-.125, -.013]), and 8FUPGT (95% CI [.002, .033]) performance.

CONCLUSION

Findings highlight the serial association of pain intensity and depressive symptoms with objective postural control performance and the potential for sleep and depression interventions that may maximize functional outcomes in FM.

Aquatic therapy improves self-reported sleep quality in fibromyalgia patients: a systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis aimed to evaluate the effectiveness of aquatic therapy on pain, sleep quality, psychological symptoms, quality of life, and health status in people diagnosed with fibromyalgia.

METHODS

We searched PubMed, CINAHL, The Cochrane Library, PEDro and Scopus databases. Articles were eligible if they were randomised controlled trials (RCTs) analysing the effects of aquatic therapy in adult people diagnosed with fibromyalgia, and published by October of 2022 in English or Spanish. The Cochrane Risk of Bias tool was employed to conduct the methodological quality assessment of the encompassed studies, and the overall quality of evidence for each comparison was determined using the GRADE approach.

RESULTS

Of 375 articles found, 22 met the inclusion criteria. Forest plot analysis of Pittsburgh sleep quality index at short- and mid-term follow-up showed a trend in favour of aquatic therapy, although not statistically significant, with weighted mean difference (WMD) = -1.71 (95% CI: -4.17 to -0.75, p = 0.17). Heterogeneity was substantial (χ2 = 8.74, df = 5 (p < 0.000001; I2 = 95%). Relating the pain outcome by fibromyalgia impact questionnaire (FIQ) short term showed a trend in favour of the aquatic therapy group with WMD = -5.04 (95% CI: - 9.26 to - 0.82, p =  = 0.02) with heterogeneity χ2 = 11.07, df = 4 (p = 0.03; I2 = 64%). Great heterogeneity was found between trials in medium term.

CONCLUSION

This systematic review and meta-analysis demonstrated the effectiveness of aquatic therapy as an adjunct treatment to usual care in people suffering from fibromyalgia. Aquatic therapeutic exercise improves the symptomats of sleep quality, pain, and quality of life of adults with fibromyalgia. Further research on long-term outcomes may contribute to the currently available evidence.

Analysis of the fatigue status of medical security personnel during the closed-loop period using multiple machine learning methods: a case study of the Beijing 2022 Olympic Winter Games

Using machine learning methods to analyze the fatigue status of medical security personnel and the factors influencing fatigue (such as BMI, gender, and wearing protective clothing working hours), with the goal of identifying the key factors contributing to fatigue. By validating the predicted outcomes, actionable and practical recommendations can be offered to enhance fatigue status, such as reducing wearing protective clothing working hours. A questionnaire was designed to assess the fatigue status of medical security personnel during the closed-loop period, aiming to capture information on fatigue experienced during work and disease recovery. The collected data was then preprocessed and used to determine the structural parameters for each machine learning algorithm. To evaluate the prediction performance of different models, the mean relative error (MRE) and goodness of fit (R2) between the true and predicted values were calculated. Furthermore, the importance rankings of various parameters in relation to fatigue status were determined using the RF feature importance analysis method. The fatigue status of medical security personnel during the closed-loop period was analyzed using multiple machine learning methods. The prediction performance of these methods was ranked from highest to lowest as follows: Gradient Boosting Regression (GBM) > Random Forest (RF) > Adaptive Boosting (AdaBoost) > K-Nearest Neighbors (KNN) > Support Vector Regression (SVR). Among these algorithms, four out of the five achieved good prediction results, with the GBM method performing the best. The five most critical parameters influencing fatigue status were identified as working hours in protective clothing, a customized symptom and disease score (CSDS), physical exercise, body mass index (BMI), and age, all of which had importance scores exceeding 0.06. Notably, working hours in protective clothing obtained the highest importance score of 0.54, making it the most critical factor impacting fatigue status. Fatigue is a prevalent and pressing issue among medical security personnel operating in closed-loop environments. In our investigation, we observed that the GBM method exhibited superior predictive performance in determining the fatigue status of medical security personnel during the closed-loop period, surpassing other machine learning techniques. Notably, our analysis identified several critical factors influencing the fatigue status of medical security personnel, including the duration of working hours in protective clothing, CSDS, and engagement in physical exercise. These findings shed light on the multifaceted nature of fatigue among healthcare workers and emphasize the importance of considering various contributing factors. To effectively alleviate fatigue, prudent management of working hours for security personnel, along with minimizing the duration of wearing protective clothing, proves to be promising strategies. Furthermore, promoting regular physical exercise among medical security personnel can significantly impact fatigue reduction. Additionally, the exploration of medication interventions and the adoption of innovative protective clothing options present potential avenues for mitigating fatigue. The insights derived from this study offer valuable guidance to management personnel involved in organizing large-scale events, enabling them to make informed decisions and implement targeted interventions to address fatigue among medical security personnel. In our upcoming research, we will further expand the fatigue dataset while considering higher precisionprediction algorithms, such as XGBoost model, ensemble model, etc., and explore their potential contributions to our research.

Effects of home-based exercise on the health of patients with fibromyalgia syndrome: a systematic review of randomized clinical trials

PURPOSE

Analyze the effects of interventions with home-based physical exercise on the health of patients with fibromyalgia and the characteristics of the protocols used.

METHODS

This systematic review was registered at PROSPERO and followed the PRISMA recommendations. Searches were performed in six electronic databases. Eligibility criteria for the selection of studies were compiled using the acronym PICOS. Data were extracted and checked in a Microsoft Excel® spreadsheet and the risk of bias was assessed using the Rob 2 tool.

RESULTS

The search resulted in seven studies included for analysis. Among them, the most common modality was aerobic exercise. The analyzed outcomes were: pain, quality of life, depression, anxiety, disease severity, physical function, pain catastrophizing, self-efficacy, psychological well-being, sleep quality and somatosensory and temporal discrimination. The effects of home-based exercise are limited, and improvements in pain and quality of life was found. For the other outcomes, the results were inconclusive. Most studies presented some concerns about the risk of bias.

CONCLUSION

It is necessary to expand the evidence on home-based exercises for fibromyalgia, as this is the first systematic review on the subject. Subsequent research should focus on methodological rigor and protocol detail, allowing findings to be replicated.

Rehabilitation of patients with inflammatory rheumatic diseases and comorbidities: unmet needs

Comorbidities may contribute to inadequate response to therapy and accelerate disability in various rheumatic diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and psoriatic arthritis (PsA). Cardiovascular, oncological, and infectious comorbidities are common in rheumatic patients. The rehabilitation of patients with inflammatory rheumatic diseases (IRDs) with comorbidities requires a multidisciplinary approach to improving patients' functional mobility, slowing down the disease progression and minimizing the risks of complications. The evidence suggests that cardiac rehabilitation can be implemented in daily practice in patients with IRDs to reduce mortality for those with established risk factors. Physical exercises reduce the severity, improve the clinical course, and reduce hospitalization rates in patients with rheumatic diseases. A rehabilitation program with focused physical therapy can lead to functional improvements and reduction of disease activity in patients with lowered quality of life (QoL). Health professionals should provide evidence-based recommendations for patients with rheumatic diseases and comorbidities to initiate the self-management of their diseases and prevent complications.

Efficacy of physical exercise on sleep quality in patients with chronic kidney disease: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

To revise and critically summarize the available scientific evidence regarding the effect of exercise on sleep quality in patients with chronic kidney disease (CKD).

METHODS

A systematic review of randomized controlled trials (RCTs) and comparative studies was conducted, searching MEDLINE/PubMed, SPORTDiscus, and Scopus using keywords "Exercise", "Physical Activity", "Chronic Kidney Disease," and "Sleep". The methodological quality of included studies was assessed using the PEDRo and MINORS scales.

RESULTS

A total of 8 RCTs and 3 comparative studies were included, showing a low (n = 1), fair (n = 7), and good (n = 3) methodological quality. Most of the studies included patients undergoing hemodialysis (HD) (n = 8). Self-reported sleep quality (n = 9), sleepiness (n = 2), and objective sleep status (n = 2) were the main outcomes analyzed. The most frequent exercise interventions included aerobic training (n = 7), resistance training (n = 2), or a combination of both (n = 4). Generally, exercise induced positive effects on the reported outcomes. Data synthesis indicated that participants who exercised obtained significant improvements on their self-reported sleep quality in comparison with those included in the control groups, with a mean difference in the Pittsburgh Sleep Quality Index of - 5.27 points (95% CI - 7.76, - 2.77; p < 0.001).

CONCLUSION

Preliminary scientific evidence indicates that patients with CKD, especially those undergoing HD, report improvements in self-reported sleep quality after taking part in aerobic exercise programs, while combined training interventions yielded diverse findings. The effects of exercise on sleepiness and objective sleep status were backed by few studies with mixed results.

Sleep profile and its correlation with clinical variables in fibromyalgia syndrome: A cross-sectional study

Objective

A scarcity of literature exists on sleep quality in fibromyalgia syndrome (FMS) in Indian patients. The current study described the sleep profile of patients with FMS with poor sleep quality residing in urban Bangalore and determined the relationship between poor sleep and fibromyalgia variables.

Methods

Eighty-six patients with FMS were included in the study. Pittsburgh Sleep Quality Index (PSQI) and Revised Fibromyalgia Impact Questionnaire (FIQR) were used to evaluate the sleep profile and fibromyalgia variables. Spearman's rank correlation, t-test, and one-way analysis of variance were used for the analyses.

Results

Ninety-one percent of patients with FMS were identified as poor sleepers (PSQI >5). The mean PSQI global score of the included patients was 12.04 ± 3.5. The global sleep score varied with sex (p = 0.003) and fibromyalgia severity (p = 0.001). A significant correlation was found between PSQI global score and FIQR total score (r = 0.4, p < 0.001), FIQR subdomains (r = 0.2-0.4, p < 0.05), and FMS duration (r = 0.26, p < 0.05). The PSQI global score was also correlated with pain, depression, memory, anxiety, balance, and sensitivity (r = 0.2-0.3, p < 0.05).

Conclusion

Sleep disturbance is highly prevalent in patients with FMS residing in urban Bangalore. Sleep quality tends to worsen in females with increasing FMS severity and duration but does not differ across other demographic variables. Sleep quality is significantly correlated with somatic as well as psychological variables. Future studies evaluating the predictors of poor sleep are needed to further corroborate these findings.

Comparative effectiveness of non-pharmacological interventions on sleep in individuals with chronic musculoskeletal pain: A systematic review with network meta-analysis

This network meta-analysis aimed to estimate the comparative effectiveness of non-pharmacological interventions on sleep in individuals with chronic musculoskeletal pain. Seven databases were systematically searched up to February 2023. A random-effects network meta-analysis in a frequentist framework was performed to synthesize continuous data as standardized mean differences (SMD) along with a 95% confidence interval (95% CI). A total of 15,641 records were identified, and 107 randomized controlled trials involving 8,121 participants were included. Of 14 identified interventions, eight were significantly more effective than passive control in improving sleep quality at immediate post-intervention (SMDs = 0.67-0.74), with cognitive behavioral therapy (CBT) being the most effective treatment (SMD = 0.74, 95% CI: 0.45-1.03). Only CBT demonstrated sustained effects at short-term (SMD = 1.56; 95% CI: 0.62-2.49) and mid-term (SMD = 1.23; 95% CI: 0.44-2.03) follow-ups. Furthermore, CBT significantly improved subjective (SMD = 0.64; 95% CI: 0.25-1.03) and objective (SMD = 0.30; 95% CI: 0.01-0.59) sleep efficiency compared with passive control at immediate post-intervention. Our findings support CBT as the first-line treatment for improving sleep in individuals with chronic musculoskeletal pain, given its superior effectiveness across multiple sleep outcomes and its sustainable effects until mid-term follow-up. However, the certainty of evidence for these interventions in improving sleep quality was very low to low.

The effectiveness of home-based therapeutic exercises on adults with fibromyalgia: a systematic review and meta-analysis

The objective of this systematic review and meta-analysis is to evaluate the effectiveness of home-based exercises (HBE) in alleviating pain, fatigue, depression, and anxiety and enhancing the quality of life (QOL) among adults with fibromyalgia. A comprehensive search was conducted across four databases PubMed, Cochrane, CINAHL (EBSCO), and PEDro to identify eligible randomized controlled trials (RCTs). Standardized mean differences (SMDs) at a 95% confidence interval (CI) were computed. Ten RCTs met the inclusion criteria, involving 601 participants, with a good-to-fair quality according to the PEDro scale. Of the 10 included studies, 3 compared HBE to no exercise, while 7 compared HBE to center-based exercises (CBE). HBE showed significant pain reduction (SMD = 0.775, P = 0.003) and improved QOL as measured by the fibromyalgia impact questionnaire (FIQ) (SMD = 0.621, P = 0.001) compared with no exercise, but there were no significant differences in depression and QOL as measured by SF-36 compared with CBE. In contrast, CBE demonstrated greater pain reduction (SMD = -1.325, P < 0.001) and improved FIQ scores (SMD = -0.843, P = 0.017) compared with HBE. In conclusion, HBE exhibit effectiveness in alleviating pain, and depression and enhancing QOL among fibromyalgia patients in comparison to no exercise. However, CBE are more effective in reducing pain and enhancing QOL than HBE, although HBE can be valuable for maintaining activity levels in fibromyalgia patients between treatment cycles.

The impact of fatigue on people with Fibromyalgia Syndrome: A survey

INTRODUCTION

Fibromyalgia syndrome (FMS) is a common pain syndrome associated with fatigue and anxiety. The aim of this survey was to determine the impact of fatigue on the quality of life (QoL) of people with FMS and to explore the relationships between fatigue, pain, and anxiety.

METHODS

A postal survey was conducted among support groups. Demographic data were collected and participants were asked to complete the Multi-dimensional Assessment of Fatigue Scale (MAF) and two visual analog scales (VAS) measuring pain and anxiety. Data were analysed using descriptive statistics, and relationships between variables were explored using Pearson's correlation coefficient and Fisher's Exact Probability Test. Ethical approval was granted from Ulster University's research ethics committee.

RESULTS

A response rate of 52.5% was achieved (105/200). Fatigue was found to severely impact the QoL of those with FMS. From the MAF, a mean Global Fatigue Index score of 40.7 (range 1 = no fatigue-50 = severe fatigue) was calculated. Fatigue was significantly associated with both pain (r = 0.674) and anxiety (r = 0.546) (both p values < 0.0001), and no significant relationship was found between the duration of FMS and fatigue (r = 0.106; p = 0.320).

CONCLUSION

Fatigue has a major impact on the QoL of patients with FMS. There is a strong relationship between fatigue and other variables such as pain and anxiety. However, there is no relationship between the time since diagnosis and fatigue experienced. Fatigue management should feature highly in any treatment programme for those with FMS.

Effectiveness of Land- and Water-based Exercise on Fatigue and Sleep Quality in Women With Fibromyalgia: The al-Ándalus Quasi-Experimental Study

OBJECTIVE

To assess the effectiveness of 24 weeks of land- and water-based exercise on fatigue and sleep quality in women with fibromyalgia, and the persistence of changes 12 weeks after exercise cessation.

DESIGN

Quasi-experimental study.

SETTING

University facilities and fibromyalgia associations.

PARTICIPANTS

Women with fibromyalgia (N=250; 50.8±7.6 years old).

INTERVENTIONS

Participants were assigned to land-based exercise (n=83), water-based exercise (n=85), or no exercise control (n=82) groups. The intervention groups engaged in a similar multicomponent exercise program for 24 weeks.

MAIN OUTCOME MEASURES

The Multidimensional Fatigue Inventory and Pittsburgh Sleep Quality Index were used.

RESULTS

Intention-to-treat analyses revealed that, compared with the control group, at week 24: (i) the land-based exercise group improved physical fatigue (mean difference -0.9 units; 95% confidence interval -1.7 to -0.1; Cohen's d=0.4) and (ii) the water-based exercise group improved general fatigue (-0.8; -1.4 to -0.1, d=0.4), and global sleep quality (-1.6; -2.7 to -0.6, d=0.6). Additionally, compared with the land-based exercise group, the water-based exercise group improved global sleep quality (-1.2; -2.2 to -0.1, d=0.4). Changes were generally not sustained at week 36.

CONCLUSION

Land-based multicomponent exercise improved physical fatigue, whereas water-based exercise improved general fatigue and sleep quality. The magnitude of the changes was small-to-medium, and no benefits were maintained after exercise cessation.

Efficacy of Sublingual Immunotherapy in Allergic Rhinitis Patients with Asthma: A Systematic Review and Meta-Analysis

OBJECTIVE

Sublingual immunotherapy (SLIT) has been widely applied to treat patients with allergic rhinitis (AR). However, meta-analyses on the efficacy of SLIT in AR patients with asthma are still limited.

METHODS

Literature without language limitation published before October 28, 2022, were retrieved from PubMed, EMBASE, and Cochrane Library. STATA 16.0 software was used for the meta-analysis of the extracted data. The results reported were symptom scores, drug scores, adverse effects rates, and cost of treatment.

RESULTS

Ten studies involving 1722 patients met the inclusion criteria. The total rhinitis score (TRSS) (weighted mean difference [WMD] = -1.23, 95% CI: -1.39--1.06, P < .001) and total asthma symptom score (TASS) (WMD = -1.00, 95% CI: -1.12-0.89, P < .001) were significantly lower in the SLIT group than the placebo group. The SLIT group had higher rates of treatment-related adverse events (relative risk [RR] = 2.82, 95% CI: 1.77-4.48, P < .001) and total costs of treatment (standardized mean difference [SMD] = 0.71, 95% CI: 0.45-0.97, P < .001). There was no significant difference in inhaled corticosteroids (ICS) dose (P = .195), fractional exhaled nitric oxide (FeNO) (P = .158), forced expiratory volume in 1 s (FEV1) (P = .237), and direct costs of treatment (P = .630) between the SLIT and placebo groups.

CONCLUSION

SLIT may be a therapeutic method for improving rhinitis symptoms and asthma symptoms in AR patients with asthma. However, as there was significant heterogeneity in results, more high-quality and well-designed studies are needed in the future to elucidate the efficacy of SLIT.

Self-regulation of effort for a better health-related quality of life: a multidimensional activity pacing model for chronic pain and fatigue management

PURPOSE

To propose a comprehensive multidimensional model of activity pacing that improves health-related quality of life and promotes sustained physical activity engagement among adults with chronic conditions.

MATERIALS AND METHODS

A narrative review was conducted to examine the existing literature on activity pacing, health-related quality of life, pain and fatigue management, and physical activity promotion in chronic conditions.

RESULTS

The literature revealed a lack of a cohesive approach towards a multidimensional model for using activity pacing to improve health-related quality of life. A comprehensive multidimensional model of activity pacing was proposed, emphasizing the importance of considering all aspects of pacing for sustained physical activity engagement and improved health-related quality of life. The model incorporates elements such as rest breaks, self-regulatory skills, environmental factors, and effective coping strategies for depression/anxiety. It takes into account physical, psychological, and environmental factors, all of which contribute significantly to the enhancement of health-related quality of life, physical function, and overall well-being, reflecting a holistic approach.

CONCLUSIONS

The model offers guidance to researchers and clinicians in effectively educating patients on activity pacing acquisition and in developing effective interventions to enhance physical activity engagement and health outcomes among adults with chronic conditions. Additionally, it serves as a tool towards facilitating discussions on sustained physical activity and a healthy lifestyle for patients, which can eventually lead to improved quality of life.

The role of symptoms severity, heart rate, and central sensitization for predicting sleep quality in patients with fibromyalgia

BACKGROUND

Clinical predictors of sleep quality in patients with fibromyalgia syndrome (FMS) are still unknown. By identifying these factors, we could raise new mechanistic hypotheses and guide management approaches. We aimed to describe the sleep quality of FMS patients and to explore the clinical and quantitative sensory testing (QST) predictors of poor sleep quality and its subcomponents.

METHODS

This study is a cross-sectional analysis of an ongoing clinical trial. We performed linear regression models between sleep quality (Pittsburgh Sleep Quality Index [PSQI]) and demographic, clinical, and QST variables, controlling for age and gender. Predictors for the total PSQI score and its seven subcomponents were found using a sequential modeling approach.

RESULTS

We included 65 patients. The PSQI score was 12.78 ± 4.39, with 95.39% classified as poor sleepers. Sleep disturbance, use of sleep medications, and subjective sleep quality were the worst subdomains. We found poor PSQI scores were highly associated with symptom severity (FIQR score and PROMIS fatigue), pain severity, and higher depression levels, explaining up to 31% of the variance. Fatigue and depression scores also predicted the subjective sleep quality and daytime dysfunction subcomponents. Heart rate changes (surrogate of physical conditioning) predicted the sleep disturbance subcomponent. QST variables were not associated with sleep quality or its subcomponents.

CONCLUSIONS

Symptom severity, fatigue, pain, and depression (but no central sensitization) are the main predictors of poor sleep quality. Heart rate changes independently predicted the sleep disturbance subdomain (the most affected one in our sample), suggesting an essential role of physical conditioning in modulating sleep quality in FMS patients. This underscores the need for multidimensional treatments targeting depression and physical activity to improve the sleep quality of FMS patients.

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

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

Physical activity levels among people with fibromyalgia: A systematic review and meta-analysis

INTRODUCTION

It is unclear how much physical activity (PA) people with fibromyalgia (PwF) engage in. We conducted a meta-analysis to examine PA levels in PwF and compared levels with age- and gender-matched controls and between objective and subjective assessments.

METHODS

Embase, PubMed and CINAHL Plus were searched by two independent reviewers from inception till 3 January 2023 using the keywords: 'fibromyalgia' OR 'fibrositis' AND 'physical activity' OR 'exercise' OR 'sports'. A random effects meta-analysis adjusting for publication bias was conducted.

RESULTS

Across 22 studies, there were 5997 (5956 women) PwF (median age = 44 years). After trim and fill adjustment, PwF spent a mean of 4.0 (95% CI = 2.3-5.8) min/day in vigorous PA, 67.5 (95% CI = 35.4-99.6) min/day in moderate intensity PA and 270.5 (95% CI = 99.6-441.4) min/day in light PA. Only 37.7% (95% CI = 18.7-61.5) of PwF achieved the public PA recommendation of 150 min of moderate to vigorous PA per week. PwF walked 5663.7 (95% CI = 4493.5-6833.9) steps per day, which is below the 6000 steps per day recommendation. PwF spent 39.0 min/day (95% CI = 22.8-55.1, p < 0.001) less in PA than healthy controls, while MET-minutes per week is 1324.7 (95 % CI = 237.6-2411.7, p = 0.017) lower. There were no significant differences between subjective and objective PA assessments (p = 0.69).

CONCLUSION

Our data demonstrate that the majority of PwF are still insufficiently physically active to obtain significant health benefits. Future clinical PA interventions specifically targeting the prevention of physical inactivity in PwF and engaging physically inactive PwF to become physically active are warranted.

Efficacy of non-pharmacological interventions: a systematic review informing the 2023 EULAR recommendations for the management of fatigue in people with inflammatory rheumatic and musculoskeletal diseases

OBJECTIVE

To identify the best evidence on the efficacy of non-pharmacological interventions in reducing fatigue in people with inflammatory rheumatic and musculoskeletal diseases (I-RMDs) and to summarise their safety in the identified studies to inform European Alliance of Associations for Rheumatology recommendations for the management of fatigue in people with I-RMDs.

METHODS

Systematic review of randomised controlled trials (RCTs) including adults with I-RMDs conducted according to the Cochrane Handbook. Search strategy ran in Medline, Embase, Cochrane Library, CINAHL Complete, PEDro, OTseeker and PsycINFO. Assessment of risk of bias, data extraction and synthesis were performed by two reviewers independently. Data were pooled in meta-analyses.

RESULTS

From a total of 4150 records, 454 were selected for full-text review, 82 fulfilled the inclusion criteria and 55 RCTs were included in meta-analyses. Physical activity or exercise was efficacious in reducing fatigue in rheumatoid arthritis (RA) (standardised mean differences (SMD)=-0.23, 95% CI=-0.37 to -0.1), systemic lupus erythematosus (SLE) (SMD=-0.54, 95% CI=-1.07 to -0.01) and spondyloarthritis (SMD=-0.94, 95% CI=-1.23 to -0.66); reduction of fatigue was not significant in Sjögren's syndrome (SMD=-0.83, 95% CI=-2.13 to 0.47) and systemic sclerosis (SMD=-0.66, 95% CI=-1.33 to 0.02). Psychoeducational interventions were efficacious in reducing fatigue in RA (SMD=-0.32, 95% CI=-0.48 to -0.16), but not in SLE (SMD=-0.19, 95% CI=-0.46 to 0.09). Follow-up models in consultations (SMD=-0.05, 95% CI=-0.29 to 0.20) and multicomponent interventions (SMD=-0.20, 95% CI=-0.53 to 0.14) did not show significant reductions of fatigue in RA. The results of RCTs not included in the meta-analysis suggest that several other non-pharmacological interventions may provide a reduction of fatigue, with reassuring safety results.

CONCLUSIONS

Physica activity or exercise and psychoeducational interventions are efficacious and safe for managing fatigue in people with I-RMDs.

Exercise-based interventions on sleep quality in patients with fibromyalgia syndrome: An umbrella and mapping review with meta-analysis

The main aim of this umbrella review was to assess the impact of exercise-based interventions (EBIs) on sleep quality in patients with fibromyalgia syndrome (FMS). We searched systematically in PubMed, PEDro, EMBASE, CINAHL, SPORTDiscus and Google Scholar. Methodological quality was analyzed using AMSTAR and ROBIS scale, and the strength of evidence was established according to GRADE. Nine systematic reviews were included. Meta-analysis (MA) of primary studies (n = 42) were performed with a random-effects model. The MA revealed a moderate statistically significant effect of EBIs (SMD=-0.46 [-0.69 to -0.23]). Subgroup analyses by type of exercise showed significant effect of body-mind exercises (SMD=-0.55 [-0.86 to -0.23]) and combined exercises (SMD=-1.11 [-2.12 to -0.11]) but not for aerobic (SMD=-0.04 [-0.15 to 0.07]) or strength (SMD=-0.52 [-1.14 to 0.1]) exercises in isolation. The results obtained showed that EBIs were effective in improving sleep quality compared to minimal intervention, no intervention or usual care, with a low certainty of evidence. Subgroup analyses showed that mind-body and combined exercises elicited the strongest effect, while aerobic and strength exercise in isolation did not show significant effects.

Effectiveness of rehabilitation strategies in primary fibromyalgia syndrome: A systematic review and meta-analysis

Objectives

The aim of this review was to (1) summarize evidence on the effectiveness of rehabilitation strategies in fibromyalgia syndrome (FMS) and (2) determine the most effective rehabilitation strategy for reducing pain and depression in people with FMS.

Data Sources

PubMed, Ovid (Sp), and Cochrane search engines were used for identifying relevant studies done up to 1st of July 2022.

Study Selection

Randomized control trials (RCTs) that have a passive control group and an active control group were included in this review for primary and secondary aim, respectively. The primary outcome measures were pain and depression. Secondary outcome was one from the sleep or fatigue or healthy related quality of life (HRQOL).

Data Extraction

Two researchers independently selected the studies and extracted the key information.

Data Synthesis

A total of 25 RCTs were included. Studies with passive control group showed moderate to large positive effects on pain (standard mean difference -0.65, 95% confidence interval -0.93 to -0.38; I2 = 72%) and HRQOL (MD -5.40, 95% CI -10.17 to -0.62; I2 = 74%) but were not statistically significant for sleep, fatigue, and depression. Furthermore, on subgroup analysis studies with a short term protocol showed significant effects on pain only, whereas studies with long term protocols showed positive effects on pain and HRQOL only, but no statistical significance at the time of post-trial follow-up. Studies with active control groups gave non-significant results except where there was mixed exercises, which showed a positive effect (mean difference -4.78, 95% CI -7.98 to -1.57; I2 = 0%) for HRQOL.

Conclusion

All rehabilitation strategies were effective for pain and HRQOL, and had a marginal effect on depression, sleep, and fatigue but efficacy was not maintained at the time of post-trial follow-up. However, in this review, we could not differentiate any rehabilitation strategies for the best among those used in the included studies.

Mechanisms hypothesized for pain-relieving effects of exercise in fibromyalgia: a scoping review

Background

Exercise is one of the most recommended management strategies by treatment guidelines for fibromyalgia (FM); however, the mechanism through which exercise improves pain in FM is still unknown.

Objective

We aimed to summarize the hypothesized theoretical mechanisms for the pain-relieving effects of exercise in people with FM.

Eligibility Criteria

Randomized controlled trials (RCTs) in English reporting mechanisms for pain-relieving effects of exercise in the 'Introduction' and 'Discussion' sections and significant within- group or between-group effects of exercise interventions were included.

Sources of Evidence

We searched the databases Ovid MEDLINE(R), EMBASE, CINAHL, COCHRANE, Sports Discuss, and AMED with the keywords: exercise and fibromyalgia until December 2021.

Charting Methods

Two authors independently performed title/abstract, full-text review, and data abstraction using a data abstraction form. The hypothesized mechanisms from individual studies were grouped into three categories.

Results

The literature search resulted in 2147 studies, out of which 220 studies were considered for full-text review. A total of 50 RCTs proposing 29 unique mechanisms for the pain-relieving effects of exercise were included. These mechanisms were divided into three categories: physical, neuro-physiological, and psychological. The neuro-physiological category was further subdivided into exercise-induced hypoalgesia (EIH), pain sensitization, the autonomic system, the immune system, the endocrine system, and miscellaneous categories. The most frequently hypothesized mechanisms were EIH (n = 15), autonomic modulation (n = 7), improved sleep (n = 6), muscle oxygenation (n = 6), self-efficacy (n = 5), mental health (n = 4), and benefits of the aquatic environment (n = 12). While all exercise interventions involved FM patients, most of the supporting evidence for these mechanisms was cited from previous studies conducted on healthy samples. No studies performed analyses to demonstrate causal associations between the mechanisms and outcomes.

Conclusion

Multiple mechanisms were hypothesized for the positive influence of exercise in people with FM. Future studies using causal analyses, such as mediation analysis, are recommended to validate these mechanisms.

Proof of concept of prehabilitation: a combination of education and behavioural change, to promote physical activity in people with fibromyalgia

OBJECTIVES

To establish proof of concept of a prehabilitation intervention, a combination of education and behavioural change, preceding a physical activity programme in people with fibromyalgia (FM).

SETTINGS

Open-label, feasibility clinical trial.

PARTICIPANTS

Eleven people with FM (10 women).

INTERVENTIONS

The prehabilitation intervention consisted of 4 weeks, 1 weekly session (~1 to 1.5 hours), aimed to increase self-efficacy and understand why and how to engage in a gentle and self-paced physical activity programme (6 weeks of walking with telephone support).

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome was the acceptability and credibility of the intervention by means of the Credibility/Expectancy Questionnaire. Secondary outcomes comprised scales to measure FM severity, specific symptoms and sedentary behaviour. An exit interview was conducted to identify the strengths and weaknesses and barriers to the intervention.

RESULTS

One participant dropped out due to finding the walking programme excessively stressful. Participants expected the intervention would improve their symptoms by 22%-38% but resulted in 5%-26% improvements. Participants would be confident in recommending this intervention to a friend who experiences similar problems. The interviews suggested that the fluctuation of symptoms should be considered as an outcome and that the prehabilitation intervention should accomodate these fluctuation. Additional suggestions were to incorporate initial interviews (patient-centred approach), to tailor the programmes to individuals' priorities and to offer a variety of physical activity programmes to improve motivation.

CONCLUSIONS

This feasibility study demonstrated that our novel approach is acceptable to people with FM. Future interventions should pay attention to flexibility, symptoms fluctuation and patients support.

TRIAL REGISTRATION NUMBER

Effects of health qigong exercise on sleep and life quality in patients with drug abuse

Objective

The aim of this study was to investigate the effect of Health Qigong (HQ) exercise on the subjective and objective sleep quality and the quality of life in male patients with drug abuse who received treatment at a mandatory drug rehabilitation residential institution.

Methods

Ninety male patients (mean age, 36.85 ± 8.72 y) were included and randomly divided into the Health Qigong (HQ) group, aerobic exercise (AE) group, or control group. The participants in the HQ and AE groups exercised four times a week for 1 hour per session for 12 weeks, while the control group maintained their original lifestyle. The following parameters were recorded before and after exercise: Pittsburgh Sleep Quality Index (PSQI); SF-36; and total sleep time, sleep efficiency, sleep latency, deep sleep time, deep sleep rate, light sleep time, and light sleep rate using actigraphy.

Results

Health Qigong improved the subjective sleep quality, objective sleep quality, and quality of life after a 12-week intervention. Considering the subjective sleep quality, Health Qigong helped improve several aspects of the PSQI, including the overall sleep quality (p < 0.01), sleep latency (p < 0.01), sleep duration (p < 0.01), sleep latency (p < 0.01), sleep disturbance (p < 0.01), and day dysfunction (p < 0.01). In relation to the objective sleep quality, Health Qigong improved the total sleep time (p < 0.01), sleep efficiency (p < 0.01), sleep latency (p < 0.01), deep and light sleep rate (p < 0.01). Considering the quality of life, Health Qigong helped improve the role-physical (p < 0.01), general health (p < 0.01), bodily pain (p < 0.01), and mental health (p < 0.01) aspects of SF-36.

Conclusion

Health Qigong may be an effective approach to improve the subjective and objective quality of sleep and life quality of patients with drug abuse.

Electroacupuncture Attenuates Fibromyalgia Pain via Toll-like Receptor 4 in the Mouse Brain

BACKGROUND

Fibromyalgia (FM) is characterized by complex pain symptoms lacking impersonal considerations in diagnosis and treatment evaluation, which often happens in women. Chronic and persistent widespread pain is the key symptom disturbing patients with FM, leading to depression, obesity, and sleep disturbances. Toll-like receptor 4 (TLR4) activation produces a harmful sensory input involved in central pain; this is the focus of this study. Electroacupuncture (EA) has beneficial effects in reducing FM pain, but its connection with TLR4 signaling is still unknown.

METHODS

Intermittent cold stress significantly induced mechanical and thermal pain. EA, but not sham EA, reliably attenuated mechanical and thermal hyperalgesia. The increased inflammatory mediators in FM mice were reduced in the EA group, but not in the sham group.

RESULTS

All TLR4 and related molecule levels increased in the FM mice's hypothalamus, periaqueductal gray (PAG), and cerebellum. These increases could be attenuated by EA but not sham stimulation. Activation of TLR4 by lipopolysaccharide (LPS) significantly induced FM and can be further reversed by a TLR4 antagonist.

CONCLUSIONS

These mechanisms provide evidence that the analgesic effect of EA is related to the TLR4 pathway. In addition, we showed that inflammation can activate the TLR4 pathway and provided new possible therapeutic targets for FM pain.

The effectiveness of exercise on global cognitive function, balance, depression symptoms, and sleep quality in patients with mild cognitive impairment: A systematic review and meta-analysis

This review aimed to examine the effectiveness of exercise on global cognitive function, balance, depression symptoms, and sleep quality in patients with mild cognitive impairment. And systematically retrieved five electronic databases, including the Cochrane library, PubMed, Embase, Web of Science, and PsycINFO, from inception to May 2022. Of 1102 studies, twenty-one studies were included in this meta-analysis. The polled results revealed that exercise could significantly improve global cognitive function (SMD = 0.64, 95%CI: 0.36 to 0.91, Z = 4.56, P < 0.00001), balance (SMD = 0.62, 95%CI: 0.30 to 0.95, Z = 4.56, P = 0.0001) and depression symptoms (SMD = -0.37, 95%CI: -0.64 to -0.10, Z = 2.70, P = 0.007). The exercise was a promising intervention with the potential to be applied in people with mild cognitive impairment.

The effect of exercise intervention on improving sleep in menopausal women: a systematic review and meta-analysis

Background

Sleep disturbance is common in menopausal women and negatively affects their quality of life and could cause increased risks of other menopause-related diseases.

Objective

This systematic review aims to synthesize evidence regarding the effects of exercise interventions on improving sleep in menopausal women.

Methods

A comprehensive search in seven electronic databases for randomized controlled trials (RCTs) was performed on June 3, 2022. The systematic review included seventeen trials, ten of which provided data for the meta-analysis. The effects on outcomes were presented as mean differences (MDs) or standard mean differences (SMDs) and their 95% confidence intervals (CI). Cochrane risk-of-bias tool was used in quality assessment.

Results

The results suggest that exercise intervention significantly reduces insomnia severity (SMD = -0.91, 95% CI = -1.45 to -0.36, Z = 3.27, P = 0.001) and alleviates sleep problems (MD = -0.09, 95% CI = -0.17 to -0.01, Z = 2.20, P = 0.03). For sleep quality, the results showed that insignificant differences were found between the exercise intervention and the control groups (MD = -0.93, 95% CI = -2.73 to 0.87, Z = 1.01, P = 0.31). The results of the subgroup analysis indicated that more apparent effects of exercise intervention were found among women with sleep disorders than among women without sleep disorders. Which exercise intervention duration was more beneficial to sleep outcomes could not be judged. Overall, there was a moderate risk of bias in the primary studies.

Conclusion

According to this meta-analysis, exercise interventions can be recommended for menopausal women to improve their sleep. High-quality RCTs applying different types of exercise (e.g., walking, yoga, meditative exercise and so on) with different intervention durations as well as subjective and objective sleep assessment are warranted.

The effect of physical activity on sleep disturbance in various populations: a scoping review of randomized clinical trials

BACKGROUND

Promoting physical activity (PA) in different populations experiencing sleep disturbance may increase population PA levels and improve sleep. This scoping review aimed to examine the effect of various PA intervention strategies on sleep across different populations, identify key sleep outcomes, and analyze knowledge gaps by mapping the relevant literature.

METHODS

For this study, we systematically searched articles published till March 2022 from PubMed, Web of Science, Cochrane Library, and Embase databases for randomized clinical trials (RCTs) regarding the effect of physical activity on sleep. Two authors extracted key data and descriptively analyzed the data. Thematic analysis was used to categorize the results into themes by all authors. Arksey and O'Malley's scoping review framework was used to present the findings.

RESULTS

Twenty-one randomized controlled trials out of 3052 studies were finally included with 3677 participants (2852 females (78%)). Five trials were conducted in healthy working-age adults with sleep disturbance but without the diagnosis of insomnia, five in healthy older adults, two in perinatal women, four in patients with cancer, three in mental illness related subjects, and another two in other disease-related areas. PA interventions were diverse, including walking, resistance training, aerobic exercise, housework, water exercise, basketball, smartphone/tablet "apps", web, online videos or wearable actigraphy, and self-determined exercise. Three major themes were identified: (1) Sleep environment may be important to address prior to instituting PA interventions, (2) All types of PA were effective for improving sleep in all populations studied, (3) Self-tolerated PA is safe for improving sleep in the elderly and in co-morbid or perinatal populations.

CONCLUSIONS

PA is effective and safe for improving sleep in both healthy and co-morbid populations with sleep disturbance by increasing daily activity levels using a variety of strategies, even low intensity, such as housekeeping, sit-to-stand repetitions, along with encouraging PA through web pages, videos, and self-goal setting apps. In addition, this scoping review identifies the need for further therapeutic research and future exploration in populations with sleep initiation or sleep maintenance disturbance.

The vicious cycle of physical inactivity, fatigue and kinesiophobia in patients with fibromyalgia syndrome

This study aims to determine the association between fatigue, kinesiophobia, disease severity, and physical inactivity by comparing fibromyalgia syndrome (FMS) patients with healthy controls. Pain and fatigue are significant barriers to the participation in functional activities. Inactivity is a result of fatigue, but exercise is the foundation of FMS treatment. This case-control study included a total of 203 participants (107 patients with FMS and 96 healthy volunteers). The fibromyalgia impact questionnaire, the fatigue severity scale, the international physical activity questionnaire, and the Tampa scale for kinesiophobia were assessed. The FMS group scored significantly higher on the fatigue severity scale and kinesiophobia than the control group (p<0.001). Significantly lower metabolic task equivalent (MET) scale values were observed in the FMS group compared to the control group (p<0.001). The severity of fatigue and kinesiophobia correlated positively with the FMS impact questionnaire (p=0.001, r=0.621) and negatively with the MET scale (p=0.009, r= -0.287). Patients with FMS experience greater fatigue, kinesiophobia, and inactivity. As the severity of FMS worsens, so do disability, kinesiophobia, and fatigue. This study highlights the importance of breaking the cycle of fatigue and inactivity in the treatment of FMS.

Understanding the Psychophysiological and Sensitization Mechanisms Behind Fibromyalgia Syndrome: A Network Analysis Approach

OBJECTIVE

Current evidence suggests that fibromyalgia syndrome (FMS) involves complex underlying mechanisms. This study aimed to quantify the multivariate relationships between clinical, psychophysical, and psychological outcomes in women with FMS by using network analysis to understand the psychobiological mechanisms driving FMS and generating new research questions for improving treatment strategies.

METHODS

Demographic (age, height, weight), clinical (pain history, pain intensity at rest and during daily living activities), psychophysical (widespread pressure pain thresholds [PPT]), sensory-related (PainDETECT, S-LANSS, Central Sensitization Inventory [CSI]) and psychological (depressive and anxiety levels) variables were collected in 126 women with FMS. Network analysis was conducted to quantify the adjusted correlations between the modeled variables and to assess their centrality indices (i.e., the connectivity with other symptoms in the network and the importance in the system modelled as network).

RESULTS

The network showed several local associations between psychophysical and clinical sensory-related variables. Multiple positive correlations between PPTs were observed, being the strongest weight between PPTs on the knee and tibialis anterior muscle (ρ: 0.33). PainDETECT was associated with LANSS (ρ: 0.45) and CSI (ρ: 0.24), whereas CSI was associated with HADS-A (ρ: 0.28). The most central variables were PPTs over the tibialis anterior (the highest Strength centrality) and CSI (the highest Closeness and Betweenness centrality).

CONCLUSION

Our findings support a model where clinical sensory-related, psychological, and psycho-physical variables are connected, albeit in separate clusters, reflecting a nociplastic condition with a relevant role of sensitization. Clinical implications of the findings, such as developing treatments targeting these mechanisms, are discussed.

Effectiveness of aquatic therapy on sleep in persons with fibromyalgia. A meta-analysis

CONTEXT

Fibromyalgia syndrome (FMS) is a chronic musculoskeletal condition characterized by persistent, widespread pain, myofascial tenderness, negative affect, fatigue, memory problems and sleep disturbances.

OBJECTIVE

To summarize the evidence of the effects of aquatic therapy on sleep quality in patients with FMS.

METHODS

This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2020 (PRISMA) guidelines and registered in the International Prospective Register of Systematic Reviews (PROSPERO), whit the registration number CRD42021249982. Cochrane library, Medline (PubMed), Science Direct Web of Science (WOS), Scopus, and PEDro were searched from inception until September 2021. The search included only randomized clinical trials.

RESULTS

Of the 7711 studies identified in the initial search, a total of 7 trials (361 participants) satisfied the eligibility criteria. Finally, a meta-analysis was conducted with 6 studies (311 participants). The overall pooled effect favored aquatic therapy interventions in improving sleep quality in patients with FMS (pooled MD, -2.05; 95% CI, -4.35 to 0.25).

CONCLUSIONS

The results of this systematic review and meta-analysis provide evidence that aquatic therapy improved sleep quality in patients with FMS. This study highlights the importance of aquatic therapy for sleep. Nonetheless, although an aquatic therapy intervention may represent a good option to improve sleep, given the low number of studies the evidence should be taken with caution.

Mediation Effect of Pain on the Relationship between Kinesiophobia and Postural Control: Comparison and Correlations in Individuals with Fibromyalgia Syndrome and Asymptomatic Individuals-A Cross-Sectional Study

Background: Individuals with fibromyalgia syndrome (FM) usually present with a fear of movement (kinesiophobia), which causes their symptoms to be maintained and exacerbated. Kinesiophobia can significantly impact postural control; ascertaining their association is crucial in evaluating and managing individuals with FM. This study aims to (1) compare postural control between individuals with FM and asymptomatic individuals, (2) estimate the relationship between kinesiophobia and postural control in individuals with FM, and (3) evaluate whether pain intensity mediates the association between kinesiophobia and postural control in individuals with FM. Methods: This study enrolled 92 individuals (mean age: 51.52 ± 7.7 years) diagnosed with FM and 106 asymptomatic individuals (mean age: 50.47 ± 6.6 years). The examiners estimated the fear of movement and the intensity of pain utilizing the Tampa scale of kinesiophobia (TSK) scores and the visual analogue scale (VAS), respectively. The postural control variables included anteroposterior (A-P) sway in mm, medio-lateral (M-L) sway in mm, and ellipse area in mm2. Results: The individuals with FM had impaired postural control compared to the asymptomatic individuals (p < 0.001). Kinesiophobia exhibited mild-to-moderate correlations with the postural control variables (nondominant side: A-P sway: r = 0.48, M-L sway: r = 0.49, ellipse area: r = 0.43. Dominant side: A-P sway: r = 0.41, M-L sway: r = 0.33, ellipse area: r = 0.44). The pain intensity significantly mediated the relationship between kinesiophobia and postural control (p < 0.001). Conclusion: Kinesiophobia showed a significant positive relationship with postural control. The individuals with FM with higher TSK scores had decreased postural control. Pain intensity mediated the relationship between kinesiophobia and postural control. These factors must be considered when evaluating and formulating treatment strategies for people with FM.

Is Pilates more effective and cost-effective than aerobic exercise in the treatment of patients with fibromyalgia syndrome? A randomized controlled trial with economic evaluation

BACKGROUND

The aim of this study was to assess the effectiveness and cost-effectiveness of Pilates versus aerobic exercises in the treatment of patients with fibromyalgia syndrome from a societal perspective.

METHODS

This two-arm randomized controlled trial with blinded assessor and economic evaluation included 98 patients diagnosed with fibromyalgia syndrome using the American College of Rheumatology 2010 criteria, aged between 20 and 75 years, and pain intensity ≥3 points in the Pain Numerical Rating Scale. Patients were randomly allocated into the aerobic or Pilates group. Treatment was performed twice a week for 8 weeks. The primary outcome was the impact of fibromyalgia measured 8 weeks after randomization. Cost-effectiveness and cost-utility analyses were conducted for the impact of fibromyalgia and quality-adjusted life-years (QALYs), respectively, with a 12-month time horizon.

RESULTS

There was no difference between the groups for the impact of fibromyalgia (MD: 6.5 points; 95% CI: -1.8 to 14.9). The incremental cost-effectiveness ratio showed that 1-point increase in the impact of fibromyalgia was on average associated with a societal cost of £56 for the Pilates group compared to the aerobic group. The cost-utility analysis showed that the Pilates group had a 0.71 probability of being cost-effective at a willingness-to-pay of £30,000 per QALY gained.

CONCLUSION

There was no significant difference between groups for the impact of fibromyalgia. Pilates was not cost-effective compared to aerobic exercises for the impact of fibromyalgia. However, Pilates seemed to be the preferred option of treatment considering QALYs, although it depends on the willingness-to-pay threshold.

SIGNIFICANCE

Pilates showed to be a safe and effective alternative for the treatment of patients with fibromyalgia syndrome. Pilates presented similar results for the impact of fibromyalgia and superior results for pain relief compared to aerobic exercises, a highly recommended intervention for the treatment of fibromyalgia syndrome. Pilates was not cost-effective compared to aerobic exercises for the impact of fibromyalgia. However, Pilates seemed to be a cost-effective intervention for QALYs, depending on the decision-maker's willingness-to-pay threshold.

Optimal dose and type of exercise to reduce pain, anxiety and increase quality of life in patients with fibromyalgia. A systematic review with meta-analysis

The aim of our meta-analysis was to compile the available evidence to evaluate the effect of physical exercise-based therapy (PEBT) on pain, impact of the disease, quality of life (QoL) and anxiety in patients with fibromyalgia syndrome (FMS), to determine the effect of different modes of physical exercise-based therapy, and the most effective dose of physical exercise-based therapy for improving each outcome. A systematic review and meta-analysis was carried out. The PubMed (MEDLINE), SCOPUS, Web of Science, CINAHL Complete and Physiotherapy Evidence Database (PEDro) databases were searched up to November 2022. Randomized controlled trials (RCTs) comparing the effects of physical exercise-based therapy and other treatments on pain, the impact of the disease, QoL and/or anxiety in patients with FMS were included. The standardized mean difference (SMD) and a 95% CI were estimated for all the outcome measures using random effect models. Three reviewers independently extracted data and assessed the risk of bias using the PEDro scale. Sixty-eight RCTs involving 5,474 participants were included. Selection, detection and performance biases were the most identified. In comparison to other therapies, at immediate assessment, physical exercise-based therapy was effective at improving pain [SMD-0.62 (95%CI, -0.78 to -0.46)], the impact of the disease [SMD-0.52 (95%CI, -0.67 to -0.36)], the physical [SMD 0.51 (95%CI, 0.33 to 0.69)] and mental dimensions of QoL [SMD 0.48 (95%CI, 0.29 to 0.67)], and the anxiety [SMD-0.36 (95%CI, -0.49 to -0.25)]. The most effective dose of physical exercise-based therapy for reducing pain was 21-40 sessions [SMD-0.83 (95%CI, 1.1--0.56)], 3 sessions/week [SMD-0.82 (95%CI, -1.2--0.48)] and 61-90 min per session [SMD-1.08 (95%CI, -1.55--0.62)]. The effect of PEBT on pain reduction was maintained up to 12 weeks [SMD-0.74 (95%CI, -1.03--0.45)].

The effectiveness of group and home-based exercise on psychological status in people with ankylosing spondylitis: A systematic review and meta-analysis

INTRODUCTION

Ankylosing spondylitis (AS) is an inflammatory rheumatic disease in which the physical impact has been evaluated; however, the psychological consequences are less well explored. The primary aim of this review was to determine the effectiveness of group versus home-based exercises on psychological status of patients with AS.

METHODS

Six databases were searched until January 2020. Eligible studies were randomised controlled trials including group or home-based exercise interventions. Risk of bias (RoB) was evaluated using the Cochrane RoB 2.0 tool. Relative percentage difference (RPD) between groups and effect sizes were presented as standardised mean differences (SMDs) with 95% confidence intervals (CI).

RESULTS

Five studies met the inclusion criteria (n = 240), outcomes of interest were depression, anxiety and mental health. Three studies were low-risk RoB, one study was high-risk RoB and one study there was 'some concerns' of bias. Group-based exercise was more effective than home-based exercise for improving depression at 6-week (RPD 18%) and 3-month (RPD 42%), anxiety (RPD 17%) and mental health (RPD 20%). Home-based exercise was more effective than control interventions for improving depression (RPD 33%). A meta-analysis demonstrated group-based exercises compared to home exercises, improved depression (SMD: -0.54; 95% CI: [-0.89; -0.18]; p = 0.003) and physical function (SMD: -0.49; 95% CI: [-0.84; -0.14]; p = 0.006).

CONCLUSION

Supervised group-based demonstrated improvements in depression, anxiety and mental health compared to home-based exercise. Individualised home-based exercise is more effective than no intervention for improving depression in people with AS.

Impact of Nonpharmacologic Interventions Targeting Sleep Disturbances or Disorders in Patients With Inflammatory Arthritis: A Systematic Review and Meta-Analysis of Randomized Trials

OBJECTIVE

Patients with inflammatory arthritis have a high risk of sleep disturbances and disorders. The objective was to evaluate the evidence of nonpharmacologic interventions targeting sleep disturbances or disorders in patients with inflammatory arthritis.

METHODS

A systematic search was undertaken from inception to September 8, 2020. We included randomized trials concerning nonpharmacologic interventions applied in adults with inflammatory arthritis and concomitant sleep disturbances or disorders. The primary outcome was the sleep domain, while secondary outcomes were core outcome domains for inflammatory arthritis trials and harms. The Cochrane Risk of Bias tool was applied, and the overall quality of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation criteria. Effect sizes for continuous outcomes were based on the standardized mean difference, combined using random-effects meta-analysis.

RESULTS

Six trials (308 patients) were included in the quantitative synthesis; 3 of these reported improvement in sleep in favor of the nonpharmacologic interventions. The meta-analysis of the sleep domains indicated a large clinical effect of -0.80 (95% confidence interval -1.33, -0.28) in favor of nonpharmacologic interventions targeting sleep disturbances or disorders. The estimate was rated down twice for risk of bias and unexplained inconsistency; this risk was assessed as corresponding to low-quality evidence. None of the secondary core outcomes used in contemporary inflammatory arthritis trials indicated a clinical benefit in favor of nonpharmacologic interventions targeting sleep.

CONCLUSION

Nonpharmacologic interventions targeting sleep disturbances/disorders in patients with inflammatory arthritis indicated a promising effect on sleep outcomes, but not yet with convincing evidence.

Fibromyalgia Pathophysiology

This article examines the biological, genetic, and environmental aspects of fibromyalgia that may have an impact on its pathogenesis. Symptoms of fibromyalgia may be related to aberrations in the endogenous inhibition of pain as well as changes in the central processing of sensory input. Genetic research has revealed familial aggregation of fibromyalgia and other related disorders like major depressive disorder. Dysfunctional pain processing may also be influenced by exposure to physical or psychological stressors, abnormal biologic reactions in the autonomic nervous system, and neuroendocrine responses. With more research the pathophysiology of fibromyalgia will be better understood, leading to more logical and focused treatment options for fibromyalgia patients.

Effects of resistance training on the physical symptoms and functional capacity of patients with fibromyalgia: a systematic review and meta-analysis of randomized clinical trials

BACKGROUND

Resistance training (RT) has become an important topic for the treatment of fibromyalgia (FM); however, there are still controversies regarding its ability to significantly improve physical symptoms and a lack of adequate recommendations for evidence-based practice.

AIM

The aim of this study is to analyze the effects of RT on the physical symptoms of patients with FM through a systematic review with meta-analysis.

METHODS

We conducted a systematic review of randomized controlled trials in June 2022, according to PRISMA recommendations. The searches were carried out on the databases PubMed, Embase, Science Direct, Web of Science, PEDro, CINAHL, SciELO, and Google Scholar for gray literature, and the protocol was recorded in PROSPERO. Studies that evaluated patients with FM undergoing an RT program lasting more than 2 weeks and that analyzed physical health were selected. To carry out the meta-analysis, the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions were followed.

RESULTS

In total, 13 studies were included for qualitative analysis and nine for meta-analysis. Regarding meta-analysis, a favorable improvement was found for pain ([MD =  - 10.22 (95% CI: - 18.86 to - 1.58; I²: 64%; P for heterogeneity: 0.003)]; very low quality of evidence {QoE}), fatigue ([SMD =  - 0.39 (95% CI: - 0.61 to - 0.17; I²: 0%; P = 0.91)]; moderate QoE), and muscle strength ([SMD = 0.94 (95% CI: 0.02 to 1.85; I²: 93%; for heterogeneity: < 0.0001)]; very low QoE) and improvement in functional capacity ([MD = 18.75 (95% CI: 4.27 to 33.22; I²: 39%; P = 0.19)]; low QoE), in the general comparison.

CONCLUSION

RT was effective in reducing pain and fatigue and increasing strength and functional capacity; however, due to the quality of the evidence, more studies are needed.

On the superiority of a combination of aerobic and resistance exercise for fibromyalgia syndrome: A network meta-analysis

Background

Fibromyalgia syndrome is the second most common chronic diffuse pain disorder and can have a lasting negative impact on the quality of life, pain, and physical function of people. Exercise therapy is an important component of the treatment of fibromyalgia, but there was not a consensus understanding of the effect of various exercise programs on the quality of life, pain, and physical function of people with fibromyalgia syndrome. This study aimed to compare three exercise programs (aerobic exercise, resistance exercise, and a combination of aerobic and resistance exercise) in their effectiveness in improving quality of life, relieving muscle pain, and enhancing physical function in patients with fibromyalgia.

Methods

A comprehensive search of databases, including China National Knowledge Internet, Wan fang, The Cochrane Library, PubMed, EMBASE, and Web of Science, was conducted to identify randomized controlled trials on exercise therapy for patients with fibromyalgia syndrome with outcome indicators including at least one of Fibromyalgia Impact Questionnaire (FIQ), Tender point count (TPC), and 6-minute walk test (6MWT) from the date of database creation on 20 April 2022. The included studies were evaluated for literature quality according to Cochrane Handbook criteria, and a network meta-analysis was performed using STATA 14.0.

Result

Forty-five randomized controlled trials met all inclusion criteria and were analyzed. The network meta-analysis showed that a combination of aerobic and resistance exercise was ranked first in all three dimensions of quality of life improvement, pain alleviation, and physical function enhancement (Mean Rank = 1.6, 1.2, 5.9).

Conclusion

The current meta-analysis demonstrates that the combination of aerobic and resistance exercise may be the best type of exercise to accentuate the quality of life, pain alleviation, and physical function for people with fibromyalgia syndrome.

A Mobile Application to Help Self-Manage Pain Severity, Anxiety, and Depressive Symptoms in Patients with Fibromyalgia Syndrome: A Pilot Study

Treatment for individuals with fibromyalgia syndrome (FMS) is complex and is not always accessible to those who could benefit. The aim of this study was to conduct a preliminary evaluation of a mobile-app-delivered, cognitive behavioral treatment (CBT)-based intervention in helping adults self-manage fibromyalgia symptoms. A total of 100 adults with FMS (M [SD] age = 49.81, [9.99] years; 94% women) were given access to the digital treatment program and downloaded the app. Pain severity, anxiety symptoms, depression symptoms, fatigue, and sleep quality were assessed at pre-treatment, post-treatment, and 3-month follow-up. Fifty-three of the potential participants completed the 47-day treatment. Data showed significant improvements in pain severity (p = 0.007, d = 0.43), anxiety (p = 0.011, d = 0.40) and depressive symptoms (p = 0.001, d = 0.50) from pre-treatment to post-treatment. The effect sizes associated with app use are consistent with improvements seen in previously published clinical trials of CBT for FMS. Improvements were generally maintained, although there was some decrease in the outcomes from post-treatment to the 3-month follow-up. Most participants reported that they were very satisfied with the app. The use of the app was associated with similar levels of improvements found with in-person CBT treatment for FMS. Research to evaluate the effectiveness of the app in a controlled trial is warranted.

Network Analysis for Better Understanding the Complex Psycho-Biological Mechanisms behind Fibromyalgia Syndrome

The aim of this study was to assess potential associations between sensory, cognitive, health-related, and physical variables in women with fibromyalgia syndrome (FMS) using a network analysis for better understanding the complexity of psycho-biological mechanisms. Demographic, clinical, pressure pain threshold (PPT), health-related, physical, and psychological/cognitive variables were collected in 126 women with FMS. A network analysis was conducted to quantify the adjusted correlations between the modeled variables and to assess the centrality indices (i.e., the degree of connection with other symptoms in the network and the importance in the system modeled as a network. This model showed several local associations between the variables. Multiple positive correlations between PPTs were observed, being the strongest weight between PPTs over the knee and tibialis anterior (ρ: 0.28). Catastrophism was associated with higher hypervigilance (ρ: 0.23) and lower health-related EuroQol-5D (ρ: −0.24). The most central variables were PPT over the tibialis anterior (the highest strength centrality), hand grip (the highest harmonic centrality) and Time Up and Go (the highest betweenness centrality). This study, applying network analysis to understand the complex mechanisms of women with FMS, supports a model where sensory-related, psychological/cognitive, health-related, and physical variables are connected. Implications of the current findings, e.g., developing treatments targeting these mechanisms, are discussed.

The Effect of Chronic Exercise on Energy and Fatigue States: A Systematic Review and Meta-Analysis of Randomized Trials

In this meta-analysis, we synthesized the results of randomized controlled trials of different exercise training interventions on participants’ feelings of fatigue, energy, and vitality. The search of studies was conducted using six databases as well as several other supplementary search strategies available before December 2021. The initial search generated over 3,600 articles with 81 studies (7,050 participants) and 172 effects meeting the inclusion criteria. We analyzed the effects from the studies using a meta-analytic multivariate model and considered the potential moderating effect of multiple variables. Our analysis revealed exercise to decrease the feelings of fatigue by a small effect size (g = −0.374; 95% CI [−0.521, −0.227]), increase energy by a small-to-moderate effect size (g = 0.415; 95% CI [0.252, 0.578]), and to increase the feeling of vitality by a moderate effect size (g = 0.537; 95% CI [0.404, 0.671]). All main results remained robust after several sensitivity analyses using different statistical estimators, and consideration of outlier and influential studies. Moreover, moderator analyses revealed significant effects of exercise intensity and intervention duration on fatigue, exercise intensity, and modality on energy, and participant health, exercise intensity modality, and exercise training location on vitality. We conclude that when groups adopt a moderate intensity exercise training program while participating in a randomized trial, compared to controls, this typically results in small-to-moderate average improvements in feelings of fatigue, energy, and vitality.

Distress and Sensitization as Main Mediators of Severity in Women with Fibromyalgia: A Structural Equation Model

We aimed to explore a path model identified using a structural equation model (SEM) which best explains the multivariate contributions of sensitization, sensitivity, and emotional variables to clinical severity in women with FMS. Pain features, the Central Sensitization Inventory (CSI), painDETECT, S-LANSS, the Hospital Anxiety and Depression Scale (HADS), the Pittsburgh Sleep Quality Index (PSQI), the Pain Catastrophizing Scale (PCS), the Pain Vigilance and Awareness Questionnaire (PVAQ), the 11-item Tampa Scale for Kinesiophobia (TSK-11), and pressure pain thresholds (PPTs) were collected from 113 women with FMS. Four latent variables were created: severity (clinical pain features), sensitivity (PPTs), sensitization (S-LANSS, CSI, painDETECT), and distress (HADS-A, HADS-D, PCS, PVAQ, TSK-11). Data fit for the measurement model were considered excellent (RMSEA = 0.043, CFI = 0.966, SRMR = 0.067, and NNFI = 0.960). Distress had a significant relationship with the mediators of sleep (β = 0.452, p = 0.031) and sensitization (β = 0.618, p = 0.001). The only mediator with a significant effect (β = 1.113, p < 0.001) on severity was sensitization. A significant indirect effect of sensitization (β = 0.687, p = 0.001) that explained the relationship between distress and severity was also identified. The proposed model suggests that distress and sensitization, together with poor sleep, have a complex mediating effect on severity in women with FMS. The identified path model can be leveraged in clinical trials investigating treatment approaches for FMS.

Effectiveness of Pain Neuroscience Education in Patients with Fibromyalgia: A Systematic Review and Meta-Analysis

PURPOSE

To assess the effects of pain neuroscience education (PNE) on patients with fibromyalgia (FM) in terms of pain intensity, fibromyalgia impact, anxiety, and pain catastrophizing.

METHODS

A systematic review and meta-analysis of randomized controlled trials was conducted. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated with RStudio software for relevant outcomes and were pooled in a meta-analysis using the random effects model.

RESULTS

A total of 8 studies were included. The meta-analysis showed statistically significant differences in the pain intensity with a moderate clinical effect in 7 studies in the post-intervention assessment (SMD:-0.76; 95% CI:-1.33- -0.19; p < 0.05) with evidence of significant heterogeneity (p < 0.05, I2=92%) but not in fibromyalgia impact, anxiety, and pain catastrophizing (p > 0.05). Regarding the follow-up assessment, only the fibromyalgia impact showed significant improvements with a very small clinical effect in 9 studies (SMD:-0.44; 95% CI:-0.73- -0.14; p < 0.05) with evidence of significant heterogeneity (p < 0.05, I2 = 80%). Applying a sensitivity analysis with the PNE face-to-face interventions, the meta-analysis showed a significant decrease of pain intensity with a moderate clinical effect at post-intervention and follow-up without evidence of significant heterogeneity (p < 0.05, I2=10%).

CONCLUSIONS

There is low quality evidence that in patients with FM, PNE can decrease the pain intensity post-intervention and also the fibromyalgia impact in the follow-up. However, it appears that PNE showed no effect on anxiety and pain catastrophizing.

Systematic Review for the Medical Applications of Meditation in Randomized Controlled Trials

Background: Meditation has been increasingly adapted for healthy populations and participants with diseases. Its beneficial effects are still challenging to determine due to the heterogeneity and methodological obstacles regarding medical applications. This study aimed to integrate the features of therapeutic meditation in randomized controlled trials (RCTs). Methods: We conducted a systematic review of RCTs with meditation for populations with diseases using the PubMed database through June 2021. We analyzed the characteristics of the diseases/disorders, participants, measurements, and their overall benefits. Results: Among a total of 4855 references, 104 RCTs were determined and mainly applied mindfulness-based (51 RCTs), yoga-based (32 RCTs), and transcendental meditation (14 RCTs) to 10,139 patient-participants. These RCTs were conducted for participants with a total of 45 kinds of disorders; the most frequent being cancer, followed by musculoskeletal and connective tissue diseases and affective mood disorder. Seven symptoms or signs were frequently assessed: depressive mood, feeling anxious, quality of life, stress, sleep, pain, and fatigue. The RCTs showed a higher ratio of positive outcomes for sleep (73.9%) and fatigue (68.4%). Conclusions: This systematic review produced the comprehensive features of RCTs for therapeutic meditation. These results will help physicians and researchers further study clinical adaptations in the future as reference data.
