Effects of water- and land-based exercises on quality of life and physical aspects in women with fibromyalgia: A randomized clinical trial

The most effective therapeutic exercises for pain intensity in women with fibromyalgia: A systematic review and network meta-analysis

BACKGROUND

Therapeutic exercise (TE) is the only intervention with strong recommendation for fibromyalgia. However, there is controversy as to which type of exercise is the most beneficial.

OBJECTIVE

To determine which TE approach is the most effective in reducing pain intensity in women with fibromyalgia.

METHODS

A systematic review was performed with a network meta-analysis (NMA). Six databases were searched from inception until January 2024. Randomized controlled trials (RCTs) evaluating the effects of TE on pain intensity were included in women with fibromyalgia. Methodological quality was assessed using the Physiotherapy Evidence Database scale. The size of the effect and the clinically important difference were determined in the short-term (≤3 months) and long-term (>3 months).

RESULTS

Sixty-one studies were identified, of which 51 were included in the quantitative synthesis (n = 2873). Fifteen TE interventions and eight comparison interventions (comparators) were identified. Aquatic exercise (p-score: 0.8713) was found to provide best benefits in the short-term and resistance training in the long-term (p-score: 0.9749). Statistically significant differences were found in favor of aquatic exercise, Pilates, qigong, resistance training, virtual reality, mixed exercise, and aerobic exercise (in the short-term) and in favor of resistance training, dance, functional training, aquatic exercise, virtual reality, and aerobic exercise (in the long-term) compared to usual care.

CONCLUSION

With a moderate level of evidence, our NMA shows that, in the short-term, aquatic exercise is the most effective TE intervention to reduce pain intensity in women with fibromyalgia, while resistance training is the most effective in the long-term. More RCTs are needed to strengthen these findings.

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

OBJECTIVE

To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia.

DESIGN

Single-blind, randomised controlled, equivalence trial.

SETTING

Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain.

PARTICIPANTS

Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20).

INTERVENTIONS

Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist.

OUTCOME

The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated.

RESULTS

The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up.

CONCLUSIONS

The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia.

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.

Effectiveness of aquatic training based on aerobic and strengthening exercises in patients with fibromyalgia: systematic review with meta-analysis

BACKGROUND AND PURPOSE

fibromyalgia is a chronic condition causing widespread pain, fatigue, limited physical function, and reduced quality of life. Aquatic training is recommended as a first-line non-pharmacological treatment. This study aims to evaluate the effectiveness of aquatic training based on aerobic and strengthening exercises in improving symptoms in women with fibromyalgia.

MATERIAL AND METHODS

a systematic review with meta-analysis was conducted by searching the PubMed, Scopus, Cochrane Library and Web of Science databases. Randomized clinical trials that compared aquatic therapy with either a control group or a land-based exercise group were included. Study quality was assessed using the PEDro scale, the risk of bias was evaluated using the Cochrane Risk of Bias Tool, and the certainty of the evidence was assessed the GRADE guidelines.

RESULTS

six randomized clinical trials comprising 9 publications showed that aquatic therapy had statistically significant benefits compared to no intervention, including pain, fatigue, fibromyalgia impact, depression, physical function, and mental health in the short term. In the medium term, improvements were observed in fibromyalgia impact, physical function, and mental health. However, aquatic therapy was not found to be superior to land-based exercise.

CONCLUSION

low to very low certainty of evidence suggested that aquatic training may reduce pain, fibromyalgia impact, fatigue and depression and improve physical function and mental health in patients with fibromyalgia. Further studies should investigate the medium and long-term effects of aquatic training using larger sample sizes.

Efficacy of aquatic exercise in chronic musculoskeletal disorders: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Aquatic exercise (AE) is becoming ever more popular as a physical therapy, while it is unclear what precise improvements it will produce and how effective it will be in comparison with other non-surgical therapies. The study aimed to assess whether AE positively impacts chronic musculoskeletal disorder patients in terms of pain, physical function, and quality of life.

METHODS

PRISMA guidelines were followed, and our study protocol was published online at PROSPERO under registration number CRD42023417411. We searched PubMed, Embase, Web of Science, and Cochrane library databases for English-language articles published before April 11, 2023, including studies from all relevant randomized controlled trials (RCTs). After screening, we ultimately included 32 RCTs with a total of 2,200 participants. We also performed subgroup analyses for all included studies. This meta-analysis calculated standardized mean difference (SMD) with 95% confidence interval (CI), and the variance was estimated using a random-effects model. The quality of the included studies was assessed by using the Cochrane collaborative "risk of bias" assessment tool (version 2.0). Thus ensuring that the literature included is of high quality.

RESULTS

This meta-analysis included 32 trials with 2,200 participants; these patients were all between the ages of 38-80. The study showed that compared to the no exercise (NE) group, patients in the AE group experienced a remarkable reduction in pain (SMD: -0.64, P < 0.001), a significant increase in physical function (SMD: 0.62, P < 0.001), and a statistically significant improvement in quality of life (SMD: -0.64, P < 0.001). When compared to land-based exercise (LE), AE significantly relieves patients' pain (SMD: -0.35, P = 0.03).

CONCLUSIONS

This is the first systematic review and meta-analysis to study whether AE could improve chronic musculoskeletal disorders. The evidence suggests that AE benefits pain, physical function, and quality of life in adults with chronic musculoskeletal conditions compared to NE. Furthermore, when compared to LE, AE continues to provide a better improvement in patient pain. More long-term clinical trials are needed to confirm AE's positive effects and improvement mechanisms and the more existential advantages compared to LE.

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.

Are OMERACT recommendations followed in clinical trials on fibromyalgia? A systematic review of patient-reported outcomes and their measures

PURPOSE

Patient-Reported Outcomes (PROs) and its measures (PROMs) are key to outcome assessment in Fibromyalgia (FM) trials. The aim of this review was to investigate which domains and instruments were assessed in recent FM trials and to compare them to recommendations by the Outcome Measures in Rheumatology (OMERACT) initiative. In addition, we investigated the overlap with a generic health assessment approach, i.e. eight domains suggested by the Patient-Reported Outcome Measurement Information System® (PROMIS®).

METHODS

In compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature search in scientific databases including PubMed, PsycInfo, and Embase was conducted to identify studies that assessed at least two dimensions of health-related quality of life (HRQoL) from 2015 to June 2022. Non-randomized and randomized controlled trials were included in the analysis. We extracted PROs and PROMs used in each study.

RESULTS

From 1845 identified records, 107 records out of 105 studies met the inclusion criteria. Studies investigated 50 PROs using 126 different PROMs. Most frequently assessed domains were pain, depression, fatigue, and anxiety (> 95% of the studies). The disease-specific FIQ was the most frequently applied PROM (82%). Overall, only 9% of the studies covered all domains deemed mandatory by OMERACT. Very few studies covered all eight generic health domains suggested by PROMIS.

CONCLUSION

The majority of trials covered most OMERACT domains or generic PROMIS health domains. There was, however, great variability in the instruments used to assess the domains, which points at a limited degree of standardization in the field.

Effect of Exercise Interventions on Health-Related Quality of Life in Patients with Fibromyalgia Syndrome: A Systematic Review and Network Meta-Analysis

OBJECTIVE

Several guidelines highlight the beneficial impact of exercise on the management of symptoms and health-related quality of life (HRQOL) in patients with fibromyalgia syndrome (FMS). However, few analyses have compared different types of exercise. We, therefore, intent to compare the effects of different exercise types on improving the overall HRQOL and typical symptoms in patients with FMS.

METHODS

Medline, Embase, the Cochrane Register of Clinical Trials, and NIH ClinicalTrials.gov were searched from inception to April 21, 2022. Randomized clinical trials (RCTs) were included to assess the impact of exercise intervention on health parameters in adult FMS patients. Data were extracted independently and a frequentist network meta-analyses (NMA) was performed to rank the effects of interventions according to P-scores. The NMA evidence certainty was assessed using the method recommended by Grading of Recommendations Assessment, Development, and Evaluation Working Group.

RESULTS

A total of 57 RCTs were identified, including 3319 participants, involving 9 interventions (7 types of exercise, 2 controls). Of all treatments compared with usual care in efficacy outcomes, Mind-body exercise was associated with the best HRQOL (SMD, -12.12; 95% CI, -15.79 to -8.45). On the other characteristic symptom dimensions, based on moderate quality evidence, sensorimotor training was associated with minimal pain scores compared with usual care (SMD, -1.81; 95% CI, -2.81 to -0.82), whole body vibration therapy was most promising for improving sleep quality (SMD, -6.95; 95% CI, -10.03 to -3.87), pool-based aerobic exercise was most likely to ease anxiety (SMD, -4.83; 95% CI, -7.47 to -2.19), and whole body vibration was most likely to improve depression (SMD, -10.44; 95% CI, -22.00 to 1.12).

CONCLUSION

Mind-body exercise seems to be the most effective exercise to improve the overall HRQOL of patients with FMS. But at the same time, clinicians still need to develop individualized exercise plans for patients according to their symptoms and accessibility.

Analysis of the Muscular Activity, Peak Torque in the Lower Limbs, and Static Balance after Virtual Rehabilitation in Women with Fibromyalgia: A Randomized Controlled Study

Objective: To analyze the effect of the exergaming on muscular activity at rest and on maximum voluntary isometric contraction by electromyography (EMG) at peak torque, widespread pressure hyperalgesia identified using a tender point count, and static balance in fibromyalgia. Materials and Methods: Thirty-five women were divided into two groups: Wii™ (virtual rehabilitation, n = 16) and control (stretching exercises, n = 19), through simple randomization. The volunteers were evaluated by means of EMG, dynamometry by load cell, baropodometry, and algometry before interventions and reevaluated after the 10th and 20th sessions. The subjects participated fully in three 1-hour treatment sessions per week of 20 sessions. Results: The Wii group showed significant benefits for the peak torque of dorsiflexion movement after 20 sessions and for movement plantarflexion after 10 sessions. The control group showed bilateral improvement in muscular activity in the tibialis anterior muscle after 20 sessions. Both groups showed a significant decrease in tender point count, suggesting improved hyperalgesia after 10 sessions and 20 sessions. No significant improvement was found in static baropodometry in the two evaluated groups. Conclusion: Exergaming have the potential to increase the peak torque for dorsiflexion and plantarflexion movement in women with fibromyalgia. It also produces a decrease in tender point count equal to that with flexibility exercises and does not produce changes in the static balance.

Effects of 12-week aerobic exercise on patient-reported outcomes in women with systemic lupus erythematosus

PURPOSE

To evaluate the effects of aerobic exercise on patient-reported outcomes (PROs) in women with systemic lupus erythematosus (SLE), and whether changes in cardiorespiratory fitness (CRF) mediate the changes in PROs.

METHODS

A total of 58 women with SLE were assigned to either an exercise group (EG; n = 26) or a control group (CG; n = 32) in this non-randomized clinical trial. The EG comprised 12 weeks of aerobic exercise (2 sessions/week) between 40%-75% of the individual's heart rate reserve. At baseline, and at week 12, CRF (Bruce test) and PROs were assessed including psychological stress (Perceived Stress Scale), sleep quality (Pittsburg Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory), depressive symptoms (Beck Depression Inventory), and quality of life (36-item Short-Form Health Survey).

RESULTS

In comparison to the CG, the EG showed a significant reduction in general fatigue (mean difference (MD) -2.86 units; 95%CI -5.70 to -0.01; p = 0.049), physical fatigue (MD -4.33 units; 95%CI -7.02 to -1.65; p = 0.002) and a non-significant reduction of reduced motivation (MD - 1.29 units; 95%CI -2.60 to 0.03; p = 0.055). There were no significant between-group differences in the changes in psychological stress, sleep quality, depressive symptoms, quality of life, or other fatigue dimensions (all p > 0.05). Changes in CRF mediated the effects of the exercise intervention on general fatigue by 53.8%.

CONCLUSION

The results suggest that 12 weeks of progressive aerobic exercise might improve relevant dimensions of fatigue in women with SLE, despite the absence of effects on other PROs. Improvements in CRF seem to mediate the effect of exercise on general fatigue.Implications for rehabilitationAerobic exercise could be safely introduced in rehabilitation programs for inactive patients with SLE with mild disease activity.Including physical activity recommendations as part of rehabilitation could improve relevant aspects of fatigue in women with SLE.When rehabilitation aims at reducing fatigue, cardiorespiratory fitness improvements derived from physical activity might enhance benefits.
