Understanding the Associations between Executive Function and Psychological Variables in Fibromyalgia Syndrome: A Network Analysis Approach

The aim of this study was to quantify the multivariate relationships between clinical, cognitive performance, executive functioning, and psychological outcomes in women with fibromyalgia (FMS) using network analyses. Demographic (age, height, weight), clinical (pain history, pain intensity, and related disability), neurocognitive (D2 Attention test, Rey-Osterrieth Complex Figure for visual perception, "Digits D/R/I" tests of the WAIS-IV battery for working memory, the 5-Digit Test for mental inhibition, the Symbol Search for processing speed and the Zoo Test for planning/decision making) and psychological (depressive symptoms, anxiety levels, sleep quality, pain hypervigilance) variables were collected in 129 women with FMS and 111 healthy women. Network analyses were conducted separately for each group to quantify the adjusted correlations between the modeled variables and to assess their centrality indices (i.e., connectivity with other symptoms in the network and their importance in the network). The network identified 74 associations in FMS women and 46 associations in controls with small differences. The strongest correlations in both groups were found between different attention variables: d2_CON with d2_C, d2_O with d_2TR, and d2_CON with d2_TA. The most central variables were d2_TA, d2_C, and d2_CON (highest strength centrality in both groups) and anxiety levels and pain hypervigilance (highest harmonic centrality in FMS women). The strength centrality of the network was stable for women with FMS (CScor0.7: 0.68) but not for healthy women (CScor0.7: 0.28). This study found that attention variables are most relevant within a neurocognitive network and that psychological variables are most important for the treatment of women with FMS. The clinical implications of the current findings, such as the development of treatments targeting these variables, are discussed.

Adherence to ACSM exercise guidelines and its influence on Fibromyalgia treatment outcomes: a meta-analysis of randomized controlled trials

Background

The Fibromyalgia Syndrome (FMS) is a multifaceted chronic pain disorder that exerts a substantial impact on the overall state of health and quality of life of patients.

Purpose

Investigate the effects of exercise therapy and adherence to the American College of Sports Medicine (ACSM) guidelines on treatment outcomes in FMS patients.

Methods

The literature search, which concluded in October 2023, encompassed studies investigating the impact of exercise interventions on patients diagnosed with FMS and providing adequate data for calculating standardized mean difference (SMD). The primary outcome measures encompassed the Fibromyalgia Impact Questionnaire (FIQ) and Health Assessment Questionnaire (HAQ), while secondary outcome measures comprised pain levels, sleep quality, fatigue, and mental health.

Results

Among 4,008 records, 19 studies (patients = 857) were eligible for qualitative synthesis. The meta-analysis revealed that the SMD for overall state of health impact was -0.94 (95%CI -1.26, -0.63), and the pooled SMD for the subgroup with high adherence to ACSM guidelines was -1.17 (95%CI -1.65, -0.69). The SMD for the subgroup with low or uncertain adherence was -0.73 (95%CI -1.12, -0.34). The overall effects included a -1.21 (95%CI -1.62, -0.79) SMD for pain relief, with high adherence achieving a -1.32 (95%CI -2.00, -0.64) SMD and low adherence a -1.06 (95%CI -1.55, -0.57) SMD. Mental health improvements showed a -0.95 (95%CI -1.32, -0.57) overall SMD, with high and low adherence subgroups at -0.96 (95%CI -1.62, -0.30) and -0.94 (95%CI -1.29, -0.60), respectively. Sleep quality impact was -1.59 (95%CI -2.31, -0.87) overall, with high adherence at -1.71 (95%CI -2.58, -0.83) and low adherence at -1.11 (95%CI -1.88, -0.33). Fatigue impact had a -1.55 (95%CI -2.26, -0.85) overall SMD, with -1.77 (95%CI -3.18, -0.36) for high adherence and -1.35 (95%CI -2.03, -0.66) for low adherence.

Conclusion

Exercise therapy can improve the overall state of health, pain, sleep, and fatigue of FMS patients, particularly when adhering to ACSM guidelines. However, adherence levels do not affect mental health gains, indicating a need for future research on psychological impact.

Comparative Analysis of Ventilatory Responses during Stress Tests in Patients with Chronic Pain: Implications for Therapeutic Interventions

Understanding the differences in ventilatory responses during exercise between patients with fibromyalgia and those with other chronic pain disorders is crucial for developing effective therapeutic interventions, especially in exercise to identify the better physical therapy prescription. Both populations face unique challenges that impact their ability to engage in physical activity; yet, the underlying physiological responses can vary significantly. In this context, the methodology of this study entailed conducting a comparative analysis of the ventilatory response during exercise in patients with fibromyalgia and those with other chronic pain disorders. The experimental protocol included a total of 31 participants (n = 13 diagnosed with fibromyalgia and n = 18 diagnosed with other chronic pain conditions). All participants completed a stress test, where the ventilatory parameters were measured in three stages (i.e., resting, incremental exercise, and recovery). The results revealed significant differences (p<0.05) in ventilatory responses between both groups. Patients with fibromyalgia exhibited reduced time for the aerobic threshold and a higher respiratory frequency in the anaerobic threshold compared to those with other chronic pain disorders. Furthermore, fibromyalgia patients demonstrated higher values in the ventilatory coefficient during the test and in the recovery stage. In conclusion, these differences underscore the need for tailored exercise programs that specifically address the unique ventilatory challenges faced by fibromyalgia patients to improve their physical function and overall quality of life.

Effects of traditional Chinese exercise therapy on pain scores, sleep quality, and anxiety-depression symptoms in fibromyalgia patients: a systematic review and meta-analysis

OBJECTIVE

This study aims to assess the effectiveness of traditional Chinese exercise therapy in alleviating pain, improving sleep quality, and reducing symptoms of anxiety and depression among fibromyalgia patients.

METHODS

We conducted a comprehensive search across various databases, including PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge, VIP database, and Wanfang, to identify randomized controlled trials (RCTs) examining the impact of Traditional Chinese Exercise (TCE) interventions on fibromyalgia. Two independent authors extracted data from the selected studies based on predefined inclusion and exclusion criteria. Meta-analyses were performed using RevMan 5.3.

RESULTS

The analysis encompassed 15 RCTs, comprising 936 participants. The meta-analysis revealed that TCE significantly surpassed the control group in reducing pain scores for fibromyalgia patients, as evidenced by improvements in FIQ [MD = -3.30, 95% CI (- 5.37, - 0.69), z = 2.53, p = 0.01] and VAS [MD = -1.87, 95% CI (- 2.12, - 1.61), z = 6.98, p < 0.00001]. Additionally, TCE demonstrated notable enhancements in sleep quality (PSQI) [MD = -2.23, 95% CI (- 2.86, - 1.61), z = 6.98, p < 0.0001], as well as in alleviating symptoms of anxiety and depression [MD = - 0.59, 95% CI (- 0.80, - 0.39), z = 5.63, p < 0.0001].

CONCLUSION

Traditional Chinese Exercise (TCE) exhibits significant efficacy in ameliorating pain, enhancing sleep quality, and alleviating symptoms of anxiety and depression in fibromyalgia patients.

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.
