The type of exercise most beneficial for quality of life in people with multiple sclerosis: A network meta-analysis

Lifestyle intervention improves cognition and quality of life in persons with early Multiple Sclerosis

BACKGROUND

Lifestyle changes have been demonstrated to impact pathophysiology in Multiple Sclerosis (MS). Various diet and exercise protocols have been reported to improve symptoms and function in persons with MS. Evidence is accumulating that interventions as early as possible in the disease course are warranted. The objective of this study was to investigate the effect of a remotely delivered lifestyle program focusing on specific diet and exercise recommendations in persons with early MS.

METHODS

MS patients, with disease diagnosis no more than 2 years prior, were recruited from the patient population of the MS clinic of the Pacific Neuroscience Institute. Participants followed recommendations for diet and exercise delivered via remote heath coaching. Each participant received 6 sessions with a health coach over a 12-week period. They were given parameters of a Mediterranean-type diet to follow, and specific and individualized recommendations about duration, intensity and type of exercise and physical activity. Outcome measures included Quality of Life (QOL), cognition (Symbol Digit Modalities Test, SDMT), fatigue (Multiple Sclerosis Fatigue Impact Scale, MFIS), fitness (estimated with Metabolic equivalents, METS) and other objective and patient reported outcomes (PRO). Changes in outcomes were analyzed using mixed effects general linear models and standardized pre-post differences.(Cohen's d) RESULTS: Fifteen persons with early (≤ 2 years) MS enrolled in the study, 14 of whom completed the study. We observed significant improvements in QOL (p = 0.02), SDMT (p = 0.006), fatigue(p = 0.005), fitness (p = 0.04), and other PRO and objective metrics at the end of the protocol compared to baseline. Adherence and patient satisfaction measures were high.

CONCLUSIONS

Specific and individualized lifestyle recommendations can be effectively delivered remotely, and may produce improvement in symptoms and function in persons with early MS. Larger controlled trials of these interventions are warranted.

Effects of Pilates-based telerehabilitation on physical performance and quality of life in patients with multiple sclerosis

PURPOSE

It is known that clinical Pilates improves strength, core stability, balance, gait, fatigue, and quality of life (QOL) in patients with multiple sclerosis (PwMS). On the other hand, there is insufficient information about whether similar benefits can be achieved with Pilates-based telerehabilitation (Pilates-TR). We aimed to investigate the effects of Pilates-TR on physical performance and QOL in PwMS.

METHODS

Thirty PwMS were recruited and randomly allocated into two groups. The Pilates-TR group received Pilates-TR via videoconferences three days per week during six weeks at home. The control group (CG) was a waitlist with no Pilates-TR treatment. Physical performance measures included extremity muscle strength, core endurance and power, balance, gait analysis, and functional exercise capacity. In addition, fatigue and QOL were evaluated.

RESULTS

Extremity muscle strength, core endurance and power, balance, walking speed, cadence, distance, functional exercise capacity, and QOL were improved after Pilates-TR (p < 0.05). Fatigue level and the effects of fatigue on functions decreased in Pilates-TR, while fatigue level increased in CG (p < .05). The CG showed no changes in any other measurements (p > .05).

CONCLUSION

Pilates-TR was effective in improving physical performance and QOL in PwMS. Pilates-TR can be recommended as an effective option, especially for patients with barriers to reaching the clinic. Trial registration: ClinicalTrials.gov (NCT04838886).

Effects of exercise in people with multiple sclerosis: a systematic review and meta-analysis

Background

A growing body of studies have examined the effect of exercise in people with multiple sclerosis (MS), while findings of available studies were conflicting. This meta-analysis aimed to explore the effects of exercise on balance, walking ability, walking endurance, fatigue, and quality of life in people with MS.

Methods

We searched PubMed, Web of Science, Scopus, and Cochrane databases, through March 1, 2024. Inclusion criteria were: (1) RCTs; (2) included an intervention and control group; (3) had people with MS as study subjects; (4) had balance, walking ability, walking endurance, fatigue, or quality of life as the outcome measures. Exclusion criteria were: (1) non-English publications; (2) animal model publications; (3) review articles; and (4) conference articles. A meta-analysis was conducted to calculate weighted mean difference (WMD) and 95% confidence interval (CI). Cochrane risk assessment tool and Physiotherapy Evidence Database (PEDro) scale were used to evaluate the methodological quality of the included studies.

Results

Forty studies with a total of 56 exercise groups (n = 1,300) and 40 control groups (n = 827) were eligible for meta-analysis. Exercise significantly improved BBS (WMD, 3.77; 95% CI, 3.01 to 4.53, P < 0.00001), TUG (WMD, -1.33; 95% CI, -1.57 to -1.08, P < 0.00001), MSWS-12 (WMD, -2.57; 95% CI, -3.99 to -1.15, P = 0.0004), 6MWT (WMD, 25.56; 95% CI, 16.34 to 34.79, P < 0.00001), fatigue (WMD, -4.34; 95% CI, -5.83 to -2.84, P < 0.00001), and MSQOL-54 in people with MS (WMD, 11.80; 95% CI, 5.70 to 17.90, P = 0.0002) in people with MS. Subgroup analyses showed that aerobic exercise, resistance exercise, and multicomponent training were all effective in improving fatigue in people with MS, with resistance exercise being the most effective intervention type. In addition, a younger age was associated with a larger improvement in fatigue. Furthermore, aerobic exercise and multicomponent training were all effective in improving quality of life in people with MS, with aerobic exercise being the most effective intervention type.

Conclusion

Exercise had beneficial effects in improving balance, walking ability, walking endurance, fatigue, and quality of life in people with MS. Resistance exercise and aerobic exercise are the most effective interventions for improving fatigue and quality of life in people with MS, respectively. The effect of exercise on improving fatigue was associated with the age of the participants, with the younger age of the participants, the greater the improvement in fatigue.

Managing multiple sclerosis in individuals aged 55 and above: a comprehensive review

Multiple Sclerosis (MS) management in individuals aged 55 and above presents unique challenges due to the complex interaction between aging, comorbidities, immunosenescence, and MS pathophysiology. This comprehensive review explores the evolving landscape of MS in older adults, including the increased incidence and prevalence of MS in this age group, the shift in disease phenotypes from relapsing-remitting to progressive forms, and the presence of multimorbidity and polypharmacy. We aim to provide an updated review of the available evidence of disease-modifying treatments (DMTs) in older patients, including the efficacy and safety of existing therapies, emerging treatments such as Bruton tyrosine kinase (BTKs) inhibitors and those targeting remyelination and neuroprotection, and the critical decisions surrounding the initiation, de-escalation, and discontinuation of DMTs. Non-pharmacologic approaches, including physical therapy, neuromodulation therapies, cognitive rehabilitation, and psychotherapy, are also examined for their role in holistic care. The importance of MS Care Units and advance care planning are explored as a cornerstone in providing patient-centric care, ensuring alignment with patient preferences in the disease trajectory. Finally, the review emphasizes the need for personalized management and continuous monitoring of MS patients, alongside advocating for inclusive study designs in clinical research to improve the management of this growing patient demographic.

Effects of physical exercise interventions on balance, postural stability and general mobility in Parkinson's disease: a network meta-analysis

OBJECTIVE

To assess which type of physical exercise intervention has the most beneficial effects on balance, postural stability and general mobility in patients with Parkinson's disease. These parameters were assessed using the Activities-specific Balance Confidence (ABC) scale, Berg Balance Scale (BBS), Mini-Balance Evaluation Systems Test (MiniBESTest) and Timed Up and Go Test (TUG).

DESIGN

Network meta-analysis.

METHODS

The PubMed, Cochrane Central Register of Controlled Trials, and Web of Science databases were searched up to August 2022 to identify randomized controlled trials on the effects of physical exercise interventions on balance, postural stability, and general mobility. The network meta-analysis included pairwise and indirect comparisons of results on the ABC scale, BBS, MiniBESTest, and TUG across 8 categories of physical exercise.

RESULTS

Eighty-six studies with a total of 4,693 patients were included. For the ABC scale, the indirect comparison showed that the highest effect size was observed for balance vs sensorimotor training without including endurance interventions (0.62; 95% confidence interval (95% CI) 0.06, 1.17). The highest effect sizes for BBS were observed for alternative exercises (1.21; 95% CI 0.62, 1.81), body-weight supported (BWS) interventions (1.31; 95% CI 0.57, 2.05), dance (1.18; 95% CI 0.33, 2.03) and sensorimotor training, including endurance interventions (1.10; 95% CI 0.46, 1.75) vs control groups. Indirect comparisons showed that the highest effect size for the MiniBESTest were observed for balance (0.75; 95% CI 0.46, 1.04) and resistance (0.58; 95% CI 0.10, 1.07) vs control groups. For the TUG, comparisons showed a significant effect size for alternative exercises (-0.54; 95% CI -0.82, -0.26), balance (-0.42; 95% CI -0.75, -0.08), resistance (-0.60; 95% CI -0.89, -0.31), and sensorimotor training including endurance interventions (-0.61; 95% CI -0.95, -0.27) vs control comparisons.

CONCLUSION

Balance interventions improve balance, postural stability, and general mobility in people with Parkinson's disease. Moreover, alternative exercises, dance, BWS interventions, resistance, and sensorimotor training, including and not including endurance interventions, are also effective.

Multiple sclerosis and exercise-A disease-modifying intervention of mice or men?

Research suggests that physical exercise can promote an anti-inflammatory and neuroprotective state. If so, increasing or optimizing exercise could be considered a 'disease-modifying intervention' in neuroinflammatory diseases, such as multiple sclerosis (MS). Exercise intervention studies conducted in animal models of MS are promising. Various aerobic and strength training regimes have been shown to delay disease onset and to reduce both the clinical and pathological disease severity in mice. However, fundamental differences between the physiology of animals and humans, the disease states studied, and the timing of exercise intervention are significant. In animal models of MS, most exercise interventions begin before disease initiation and before any clinical sign of disease. In contrast, studies in humans recruit participants on average nearly a decade after diagnosis and often once disability is established. If, as is thought to be the case for disease-modifying treatments, the immunomodulatory effect of exercise decreases with advancing disease duration, current studies may therefore fail to detect the true disease-modifying potential. Clinical studies in early disease cohorts are needed to determine the role of exercise as a disease-modifying intervention for people with MS.

Feasibility of Telerehabilitation-Based Pelvic Floor Muscle Training for Urinary Incontinence in People With Multiple Sclerosis: A Randomized, Controlled, Assessor-Blinded Study

BACKGROUND AND PURPOSE

Urinary incontinence is a common symptom in people with multiple sclerosis. The primary aim was to investigate feasibility of telerehabilitation-based pelvic floor muscle training (Tele-PFMT) and compare its effects on leakage episodes and pad usage with home exercise-based pelvic floor muscle training (Home-PFMT) and control groups.

METHODS

Forty-five people with multiple sclerosis with urinary incontinence were randomized into 3 groups. Tele-PFMT and Home-PFMT groups followed the same protocol for 8 weeks, but Tele-PFMT performed exercises 2 sessions/week under a physiotherapist's supervision. The control group did not receive any specific treatment. Assessments were made at baseline, weeks 4, 8, and 12. Primary outcome measures were feasibility (compliance to exercise, patient satisfaction, and number of participants included in the study), number of leakage episodes, and pad usage. Secondary outcomes included severity of urinary incontinence and overactive bladder symptoms, sexual function, quality of life, anxiety, and depression.

RESULTS

Participant eligibility rate was 19%. Patient satisfaction and compliance to exercise were significantly higher in Tele-PFMT than in Home-PFMT ( P < 0.05). No significant differences in the change of leakage episodes and pad usage were found between Tele-PFMT and Home-PFMT. No significant differences in secondary outcomes were found between PFMT groups. Participants in both the Tele-PFMT and Home-PFMT groups had significantly better scores for some measures of urinary incontinence, and overactive bladder and quality of life in compared with the control group.

DISCUSSION AND CONCLUSIONS

Tele-PFMT was feasible and acceptable in people with multiple sclerosis, and this mode of delivery was associated with greater exercise compliance and satisfaction compared with Home-PFMT. However, Tele-PFMT did not exhibit superiority in terms of leakage episodes and pad usage compared with Home-PFMT. A large trial comparing Home-PFMT and Tele-PFMT is warranted.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content, available at: http://links.lww.com/JNPT/A440 ).

Engagement with three or more healthy lifestyle behaviours is associated with improved quality of life over 7.5 years in people with multiple sclerosis

BACKGROUND AND PURPOSE

People with multiple sclerosis (pwMS) report reduced quality of life (QoL). Engagement with healthy lifestyle behaviours, including consuming a healthy diet, regular physical activity, and adequate vitamin D exposure, is associated with higher QoL. We aim to assess whether individual lifestyle behaviours are more beneficial to QoL than others, and whether there are additive benefits to QoL by engaging in multiple healthy behaviours concurrently.

METHODS

Data from pwMS who completed an online survey at baseline, and at 2.5-, 5- and 7.5-year follow-up, were analysed. Behaviours assessed were consumption of a no-meat/dairy-plus-omega-3 supplementation diet, meditation practice, physical activity, non-smoking, and vitamin D exposure. Mental QoL (mQoL) and physical QoL (pQoL) were assessed by the Multiple Sclerosis Quality of Life (MSQOL-54) questionaire. Linear regression analyses were performed to assess associations of individual behaviours at baseline and follow-up time points with QoL, as well as between number of behaviours and QoL.

RESULTS

At baseline, healthy diet and regular physical activity were associated with higher mQoL (5.3/100 and 4.0/100) and higher pQoL (7.8/100 and 6.7/100). Prospectively, diet was positively associated with mQoL, and physical activity with both mQoL and pQoL. At baseline, engagement with ≥3 behaviours was positively associated with mQoL and pQoL, with additive positive associations for each additional behaviour. Prospectively, engagement with ≥3 behaviours was positively associated with mQoL and pQoL, with strongest associations observed with engagement with five behaviours.

CONCLUSION

Consumption of a healthy diet, and regular physical activity, are both potential interventions to improve QoL. Engagement with multiple lifestyle behaviours may provide additional benefits and should be encouraged and supported for multiple sclerosis management.

Effects of inpatient energy management education and high-intensity interval training on health-related quality of life in persons with multiple sclerosis: A randomized controlled superiority trial with six-month follow-up

BACKGROUND

Fatigue is one of the most frequent symptoms in persons with multiple sclerosis (pwMS) and impacts health-related quality of life (HRQoL). A multidisciplinary rehabilitation approach is recommended for the treatment of fatigue in pwMS. However, high-quality evidence exists only for unimodal interventions, such as physical therapies/exercise or energy/fatigue management programmes. The primary objective of the current study was to test the hypothesis that a combination of inpatient energy management education (IEME) and high-intensity interval training (HIIT) is superior to a combination of progressive muscle relaxation (PMR) and moderate continuous training (MCT) for improving HRQoL at 6-month follow-up in fatigued pwMS.

METHODS

A randomized (1:1) controlled superiority trial with fatigued pwMS >18 years of age, with Expanded Disability Status Scale (EDSS) score ≤6.5, recruited at the Valens clinic, Switzerland. Participants in the experimental group performed IEME twice and HIIT 3 times per week and those in the usual care group performed PMR twice and MCT 3 times per week, during a 3-week inpatient rehabilitation stay. Primary outcome was HRQoL (Physical and Mental Component Scales of the Medical Outcome Study 36-item Short Form Health Survey (SF-36)), assessed at entry to the clinic (T0), after 3 weeks' rehabilitation (T1) and 4 (T2) and 6 (T3) months after T0. Secondary outcomes included SF-36 subscales, fatigue (Fatigue Scale for Motor and Cognitive Functions (FSMC)), mood (Hospital Anxiety and Depression Scale (HADS)), self-efficacy for performing energy conservation strategies (Self-Efficacy for Performing Energy Conservation Strategies Assessment (SEPECSA)), self-perceived competence in activities of daily living (Occupational Self Assessment (OSA)) and cardiorespiratory fitness (peak oxygen consumption (VȮ2peak)). Data were analysed using a mixed model for repeated measures approach.

RESULTS

A total of 106 pwMS (age (years): 49.75 (9.87), 66% female, EDSS: 4.64 (1.32)) were recruited. There were no significant group × time interaction effects in the primary and secondary outcomes. There were significant between-group differences in the pairwise comparisons of the group × time interaction in favour of the IEME + HIIT group at: (i) T1 in cardiorespiratory fitness (p = 0.011) and SEPECSA (p = 0.032); (ii) T2 in SF-36 mental health subscale (p = 0.022), HADS anxiety subscale (p = 0.014) and SEPECSA (p = 0.040); (iii) T3 in SF-36 physical functioning subscale (p = 0.012) and SEPECSA (p = 0.003).

CONCLUSION

IEME + HIIT was not superior to PMR + MCT regarding the effects on HRQoL (SF-36 Physical and Mental Component Scales) at 6-month follow-up in pwMS. However, there were significant between-group differences in favour of IEME + HIIT in physical functioning and mental health (SF-36 subscales), anxiety (HADS), cardiorespiratory fitness (VȮ2peak) and self-efficacy (SEPECSA) at different measurement time-points that need to be considered in clinical practice.

Effect of different types of exercise on fitness in people with multiple sclerosis: A network meta-analysis

BACKGROUND

It is assumed that people with multiple sclerosis (MS) who participate in programs of physical exercise improve their physical fitness.

OBJECTIVE

The aim of this network meta-analysis (NMA) was to analyze the effect of different types of exercise on muscular fitness and cardiorespiratory fitness (CRF) among people with MS and to determine the best type of exercise according to disease severity.

METHODS

MEDLINE, the Physiotherapy Evidence Database, the Cochrane Library, SPORTDiscus, Scopus, and Web of Science were searched from inception to April 2022 to identify randomized controlled trials (RCTs) concerning the effect of physical exercise on fitness in people with MS. We ranked the types of physical exercise by calculating the surface under the cumulative ranking (SUCRA).

RESULTS

We included 72 RCTs involving 2543 MS patients in this NMA. A ranking of five types of physical exercise (aerobic, resistance, combined [aerobic and resistance], sensorimotor training, and mind-body exercises) was achieved. Combined and resistance training had the highest effect sizes (0.94, 95% CI 0.47, 1.41, and 0.93, 95% CI 0.57, 1.29, respectively) and the highest SUCRA (86.2% and 87.0%, respectively) for muscular fitness. The highest effect size (0.66, 95% CI 0.34, 0.99) and SUCRA (86.9%) for CRF was for aerobic exercise.

CONCLUSIONS

Combined and resistance training seem to be the most effective exercises to improve muscular fitness and aerobic exercise for CRF in people with MS.

Effects of aerobic, resistance, and combined exercise training on health-related quality of life in multiple sclerosis: Systematic review and meta-analysis

BACKGROUND

Multiple sclerosis (MS) is an immune-mediated, neurodegenerative disease of the central nervous system that manifests in symptoms that compromise health-related quality of life (HRQOL). HRQOL focuses on a person's overall, subjective evaluation of health status primarily in the physical and mental domains. Exercise training is a form of rehabilitation for managing MS-related outcomes that might influence HRQOL. Reviews on exercise training are available, but we are unaware of a recent comprehensive review and meta-analysis of exercise effects for improving physical and mental domains of HRQOL. This analysis provides an updated review and meta-analysis of randomized controlled trials (RCTs) examining interventions consisting of aerobic, resistance and combined exercise training for improving HRQOL in persons with MS. This systematic review 1) assessed the overall strength of evidence for exercise interventions on HRQOL, 2) evaluated the relative effect of exercise interventions on physical and mental domains of HRQOL, and 3) determined moderators of exercise intervention effects on HRQOL.

METHODS

Seven databases were searched for RCTs evaluating physical and/or mental domains of HRQOL with adults diagnosed with MS and undergoing an intervention of aerobic, resistance or combined exercise training compared with a non-exercise comparator. Data extraction included participant and intervention characteristics, and pre- and post-intervention HRQOL outcome data. Effect sizes (ESs) were calculated as standardized mean differences (SMDs) and a multilevel random-effects model was used to generate an aggregated SMD that compared exercise with non-exercise control conditions.

RESULTS

Twelve RCTs met the inclusion criteria and yielded 23 ESs to be analyzed. Participants (N = 593; 308 intervention vs. 285 control conditions) had a mean (±standard deviation) age of 42.4 (6.5) years and 80% (18.3%) were female. Results generated a medium effect of exercise for improving overall HRQOL (ES=0.64, p = 0.0001) with high heterogeneity (Q₁₁=58.8, I²=86.7%). Exercise training yielded a large effect on the physical domain (k = 12, ES=0.82, p<0.0009) and a medium effect on the mental domain (k = 11, ES=0.41, p<0.0001). Moderator analyses identified exercise modality, supervision level, intervention delivery and length, HRQOL tool, and number of participants with relapsing-remitting MS as significant influences of ES for HRQOL.

CONCLUSIONS

Exercise training is clinically effective for improving overall HRQOL in MS and produces greater improvements in the physical domain of HRQOL than the mental domain. The moderator analysis suggests that supervised, aerobic, and group-delivered exercise training of ≥3 months yields the most influence on HRQOL. Such results may have major implications for MS treatment and care.

Physical Exercise Interventions on Quality of Life in Parkinson Disease: A Network Meta-analysis

BACKGROUND AND PURPOSE

Physical exercise is considered an effective intervention for maintaining or improving quality of life (QoL) in patients with Parkinson disease (PD), but there is no evidence showing which type of physical exercise intervention has more positive effects. This systematic review and meta-analysis aimed to synthesize the evidence regarding the effectiveness of exercise interventions on improving QoL in patients with PD, comparing different types of exercise interventions.

METHODS

A literature search was conducted through January 2022. The methodological quality of the trials was assessed using the Cochrane risk of bias tool RoB2. For the meta-analysis, physical exercise interventions were classified into 5 training categories: resistance, endurance, alternative exercises, dance, and sensorimotor interventions. A standard meta-analysis and network meta-analysis were carried out to evaluate the efficacy of the different types of physical exercise interventions.

RESULTS

The search retrieved 2451 studies, 48 of which were included in this network meta-analysis with a total of 2977 patients with PD. The indirect effects of the network meta-analysis showed positive results for alternative exercises (-0.46; 95% confidence interval [CI]: -0.76, -0.16), dance (-0.63; 95% CI: -1.08, -0.17), and sensorimotor interventions (-0.23; 95% CI: -0.40, -0.07) versus control comparisons.

DISCUSSION AND CONCLUSIONS

More research is needed to determine the types of physical exercise interventions that are most beneficial and for which conditions of the disease they have the most positive effects.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A398 ).

Investigation of in-phase bilateral exercise effects on corticospinal plasticity in relapsing remitting multiple sclerosis: A registered report single-case concurrent multiple baseline design across five subjects

Relapsing-remitting Multiple Sclerosis is the most common demyelinating neurodegenerative disease and is characterized by periods of relapses and generation of various motor symptoms. These symptoms are associated with the corticospinal tract integrity, which is quantified by means of corticospinal plasticity which can be probed via transcranial magnetic stimulation and assessed with corticospinal excitability measures. Several factors, such as exercise and interlimb coordination, can influence corticospinal plasticity. Previous work in healthy and in chronic stroke survivors showed that the greatest improvement in corticospinal plasticity occurred during in-phase bilateral exercises of the upper limbs. During in-phase bilateral movement, both upper limbs are moving simultaneously, activating the same muscle groups and triggering the same brain region respectively. Altered corticospinal plasticity due to bilateral cortical lesions is common in MS, yet, the impact of these type of exercises in this cohort is unclear. The aim of this concurrent multiple baseline design study is to investigate the effects of in-phase bilateral exercises on corticospinal plasticity and on clinical measures using transcranial magnetic stimulation and standardized clinical assessment in five people with relapsing-remitting MS. The intervention protocol will last for 12 consecutive weeks (30-60 minutes /session x 3 sessions/week) and include in-phase bilateral movements of the upper limbs, adapted to different sports activities and to functional training. To define functional relation between the intervention and the results on corticospinal plasticity (central motor conduction time, resting motor threshold, motor evoked potential amplitude and latency) and on clinical measures (balance, gait, bilateral hand dexterity and strength, cognitive function), we will perform a visual analysis and if there is a potential sizeable effect, we will perform statistical analysis. A possible effect from our study, will introduce a proof-of-concept for this type of exercise that will be effective during disease progression. Trial registration: ClinicalTrials.gov NCT05367947.

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.
