A comprehensive review of 46 exercise treatment studies in fibromyalgia (1988-2005)

A Comparative Study on the Pain Threshold Experienced by Fibromyalgia Patients Following Acute SARS-CoV-2 Infection

Significant gaps remain in the understanding of the etiology and pathogenesis of fibromyalgia (FM), and the COVID-19 pandemic has introduced even more unknowns. Social factors specific to that period, the viral infection itself, and/or vaccination are additional elements that can complicate the progression of the disease or the response to treatment. Aim: The primary hypothesis to be evaluated in this study is that an acute COVID-19 infection, even when considered recovered, may induce changes in the response to non-pharmacological treatment in FM patients, particularly concerning pain. Results: We included 128 patients diagnosed with FM before the pandemic began. The patients were divided based on their history of acute SARS-CoV-2 infection and COVID-19 vaccination status. All patients followed the same rehabilitation program (cognitive therapy, kinesitherapy). Perceived pain: The non-COVID-19 patient groups showed a statistically significant reduction in pain at the final evaluation compared to patients with a history of acute SARS-CoV-2 infection (p < 0.001). Algometric evaluation: Patients without COVID-19 infection and that were vaccinated exhibited the best improvement in pain threshold, both across evaluation times (p < 0.001) and compared to any of the other three groups studied (p < 0.001). Using the WHYMPI questionnaire, the same group of patients (those not having experienced acute COVID-19 and who were vaccinated) was the only group with a statistically significant improvement in pain severity (p = 0.009). In conclusion, to control and improve FM pain symptoms, in addition to appropriate medication, we propose paying additional attention to the history of acute SARS-CoV-2 infection and the COVID-19 vaccination status.

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 Role of Physical Exercise in Chronic Musculoskeletal Pain: Best Medicine-A Narrative Review

The aim of this paper is to provide a narrative review of the effects of physical exercise in the treatment of chronic musculoskeletal pain. Physical inactivity and sedentary behavior are associated with chronic musculoskeletal pain and can aggravate it. For the management of musculoskeletal pain, physical exercise is an effective, cheap, and safe therapeutic option, given that it does not produce the adverse effects of pharmacological treatments or invasive techniques. In addition to its analgesic capacity, physical exercise has an effect on other pain-related areas, such as sleep quality, activities of daily living, quality of life, physical function, and emotion. In general, even during periods of acute pain, maintaining a minimum level of physical activity can be beneficial. Programs that combine several of the various exercise modalities (aerobic, strengthening, flexibility, and balance), known as multicomponent exercise, can be more effective and better adapted to clinical conditions. For chronic pain, the greatest benefits typically occur with programs performed at light-to-moderate intensity and at a frequency of two to three times per week for at least 4 weeks. Exercise programs should be tailored to the specific needs of each patient based on clinical guidelines and World Health Organization recommendations. Given that adherence to physical exercise is a major problem, it is important to empower patients and facilitate lifestyle change. There is strong evidence of the analgesic effect of physical exercise in multiple pathologies, such as in osteoarthritis, chronic low back pain, rheumatoid arthritis, and fibromyalgia.

The effectiveness of aerobic exercise for pain management in patients with fibromyalgia

The effectiveness of exercise therapy is being increasingly studied in patients with fibromyalgia. The aim of our systematic review was to determine the effectiveness of different types of aerobic exercise programs for pain management in patients with fibromyalgia. The literature search was performed by two independent researchers in the PubMed, CINAHL and PEDro databases using various combinations of the following keywords: fibromyalgia, pain and aerobic exercise. Studies were eligible if they included adults diagnosed with fibromyalgia and examined the effectiveness of at least one aerobic exercise program on pain management. A total of 14 randomized controlled trials were screened in full-text, nine of which were included in the systematic review. Overall, our results indicate that aerobic exercise is effective for pain management in patients with fibromyalgia. The results of the aerobic exercise programs were more effective for pain management than stretching exercises, but did not differ significantly from those of pilates, muscle strengthening exercises, relaxation techniques and stress management treatment. Additional high-quality studies are warranted to determine accurate clinical guidelines in terms of aerobic exercise programs for pain management in patients with fibromyalgia.

Can an Aerobic Exercise Programme Improve the Response of the Growth Hormone in Fibromyalgia Patients? A Randomised Controlled Trial

Downgrade alterations in the growth hormone (GH) might be involved in the development of some of the fibromyalgia syndrome (FMS) symptoms. Our aim was to assess the effects of an aerobic exercise programme on the GH levels in patients with FMS. A randomised controlled trial was developed. Sixty-four Spanish women with FMS were randomly assigned to the experimental arm (n = 33) and treated with a 16-week group physical exercise programme based on low impact aerobic dance (three weekly sessions, one-hour each), or to the treatment-as-usual (TAU) control arm (n = 31). The primary outcome was the GH response to acute exercise. Secondary outcomes were GH basal, sensitivity to pain, body composition, aerobic capacity, and quality of life. The ANCOVA results showed a moderate effect of treatment improving the GH response to acute exercise. Other effects were substantial for aerobic capacity, quality of life, and body composition. Pre-intervention GH response to acute exercise was related to improvements in aerobic capacity and quality of life. An aerobic exercise programme may improve the response of the GH, aerobic capacity, body composition, and quality of life in women with FMS. The normalization of neuro-hormonal patterns involving the GH might be key for improving some FMS symptoms.

Effectiveness, cost-utility and physiological underpinnings of the FIBROWALK multicomponent therapy in online and outdoor format in individuals with fibromyalgia: Study protocol of a randomized, controlled trial (On&Out study)

Introduction: The On&amp;Out study is aimed at assessing the effectiveness, cost-utility and physiological underpinnings of the FIBROWALK multicomponent intervention conducted in two different settings: online (FIBRO-On) or outdoors (FIBRO-Out). Both interventions have proved to be efficacious in the short-term but there is no study assessing their comparative effectiveness nor their long-term effects. For the first time, this study will also evaluate the cost-utility (6-month time-horizon) and the effects on immune-inflammatory biomarkers and Brain-Derived Neurotrophic Factor (BDNF) levels of both interventions. The objectives of this 6-month, randomized, controlled trial (RCT) are 1) to examine the effectiveness and cost-utility of adding FIBRO-On or FIBRO-Out to Treatment-As-Usual (TAU) for individuals with fibromyalgia (FM); 2) to identify pre–post differences in blood biomarker levels in the three study arms and 3) to analyze the role of process variables as mediators of 6-month follow-up clinical outcomes.

Methods and analysis: Participants will be 225 individuals with FM recruited at Vall d’Hebron University Hospital (Barcelona, Spain), randomly allocated to one of the three study arms: TAU vs. TAU + FIBRO-On vs. TAU + FIBRO-Out. A comprehensive assessment to collect functional impairment, pain, fatigue, depressive and anxiety symptoms, perceived stress, central sensitization, physical function, sleep quality, perceived cognitive dysfunction, kinesiophobia, pain catastrophizing, psychological inflexibility in pain and pain knowledge will be conducted pre-intervention, at 6 weeks, post-intervention (12 weeks), and at 6-month follow-up. Changes in immune-inflammatory biomarkers [i.e., IL-6, CXCL8, IL-17A, IL-4, IL-10, and high-sensitivity C-reactive protein (hs-CRP)] and Brain-Derived Neurotrophic Factor will be evaluated in 40 participants in each treatment arm (total n = 120) at pre- and post-treatment. Quality of life and direct and indirect costs will be evaluated at baseline and at 6-month follow-up. Linear mixed-effects regression models using restricted maximum likelihood, mediational models and a full economic evaluation applying bootstrapping techniques, acceptability curves and sensitivity analyses will be computed.

Ethics and dissemination: This study has been approved by the Ethics Committee of the Vall d’Hebron Institute of Research. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media and various community engagement activities. Trial registration number NCT05377567 (clinicaltrials.gov).

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.

The Pain Outcomes Comparing Yoga vs. Structured Exercise (POYSE) Trial in Veterans With Fibromyalgia: Study Design and Methods

Background

Fibromyalgia is a common pain condition that often leads to significant disability. Unfortunately, the effectiveness of most medications for fibromyalgia is limited, and there is a need for alternative, non-pharmacological therapies. Yoga and aerobic exercise are both evidence-based non-pharmacological treatments for fibromyalgia. However, no prior studies have directly compared the effectiveness of yoga vs. exercise.

Objective

This article describes the study design and recruitment outcomes of the Pain Outcomes comparing Yoga vs. Structured Exercise (POYSE) Trial, a two-arm randomized comparative effectiveness trial.

Methods

Veterans with fibromyalgia, defined by the 2010 American College of Rheumatology diagnostic criteria, who also experienced at least moderate pain severity were enrolled. The participants were randomized to a 12-week yoga-based or a structured exercise program (SEP) and will undergo comprehensive outcome assessments at baseline, 1, 3, 6, and 9 months by interviewers blinded to treatment assignment. The primary outcome will be the overall severity of fibromyalgia as measured by the total Fibromyalgia Impact Questionnaire-Revised. Secondary outcomes included depression, anxiety, health-related quality of life, pain beliefs, fatigue, sleep, and self-efficacy.

Results

A total of 2,671 recruitment letters were sent to potential participants with fibromyalgia. Of the potential participants, 623 (23.3%) were able to be contacted by telephone and had their eligibility assessed. Three hundred seventy-one of those interviewed were found to be eligible (59.6%) and 256 (69.0%) agreed to participate and were randomized to the YOGA (n = 129) or the SEP (n = 127) arm of the trial.

Conclusions

Clinicians are faced with numerous challenges in treating patients with fibromyalgia. The interventions being tested in the POYSE trial have the potential to provide primary care and other care settings with new treatment options for clinicians while simultaneously providing a much needed relief for patients suffering from fibromyalgia.

Effects of a physical self-care support program for patients with fibromyalgia: A randomized controlled trial

BACKGROUND

The effects of stretching exercises in fibromyalgia (FM) deserves further study.

OBJECTIVE

To evaluate the effectiveness of a Physical Self-Care Support Program (PSCSP), with emphasis on stretching exercises, in the treatment of FM.

METHODS

Forty-five women with FM were randomized to the PSCSP (n= 23) or to a control group (n= 22). The PSCSP consisted of weekly 90-minute learning sessions over 10 weeks, providing instructions on wellness, postural techniques, and active stretching exercises to be done at home. The control group was monitored through 3 medical appointments over 10 weeks and included in a waiting list. The primary outcomes were the Fibromyalgia Impact Questionnaire (FIQ), the Visual Analogue Scale (VAS) for pain, and the Sit and Reach Test (SRT) at the end of the study.

RESULTS

Nineteen and 21 patients completed the trial in PSCSP and control groups, respectively. After 10 weeks, the PSCSP group showed significantly better FIQ (difference between adjusted means, -13.64, 95% CI, -21.78 to -5.49, P= 0.002) and SRT scores (7.24 cm, 3.12 to 11.37, P= 0.001) than the control group, but no significant difference in pain VAS (-1.41, -3.04 to 0.22, P= 0.088). Analysis using multiple imputation (MI) and delta-adjusted MI for missing outcomes rendered similar results.

CONCLUSIONS

A PSCSP emphasizing stretching exercises significantly improved FIQ and SRT scores, and may be a helpful therapy for FM.

Effects of different types of exercises on pain, quality of life, depression, and body composition in women with fibromyalgia: A three-arm, parallel-group, randomized trial

Objectives

This study aims to compare the efficacy of three different exercise types on pain, health-related quality of life (HRQoL), depression, and body composition in women with fibromyalgia (FM).

Patients and methods

Between June 2019 and December 2019, a total of 41 women with FM (mean age: 46.7+9.4 years; range, 24 to 62 years) were randomly allocated into Group 1 (n=13, supervised aerobic plus stretching), Group 2 (n=13, supervised resistance plus stretching), and Group 3 (n=15, home-based stretching). All exercises were performed three times per week for 12 weeks and were individualized by measuring the maximal oxygen consumption (VO_2max) for aerobic exercise and one-repetition maximum (1-RM) test for resistance exercise. The main measures were pain intensity assessed by the Visual Analog Scale (VAS), severity by the Fibromyalgia Impact Questionnaire (FIQ), symptoms of depression by the Beck Depression Inventory, HRQoL by the Short-Form Health Questionnaire (SF-36), and body composition by bioelectrical impedance analysis.

Results

The mean VAS difference (95% confidence interval [CI]): -2.61 (-1.94, -3.29); -2.61 (-1.82, -3.42); -1.07 (-0.49, -1.64) for Group 1, Group 2, and Group 3, respectively (p<0.001); however, there was no significant difference between the combined exercise groups. The FIQ scores decreased significantly in all exercise groups after training (p<0.05). At 12 weeks, 21 (80.8%) patients from combined groups and six (40%) patients from the stretching alone group achieved a minimal clinically significant difference defined as a 14% change in baseline FIQ scores (p=0.008). Other outcome parameters did not differ significantly among the groups.

Conclusion

Supervised aerobics/muscle strengthening combined with stretching exercises reduced pain, and FM severity more than a home stretching exercise alone.

Physiological Changes and Pathological Pain Associated with Sedentary Lifestyle-Induced Body Systems Fat Accumulation and Their Modulation by Physical Exercise

A sedentary lifestyle is associated with overweight/obesity, which involves excessive fat body accumulation, triggering structural and functional changes in tissues, organs, and body systems. Research shows that this fat accumulation is responsible for several comorbidities, including cardiovascular, gastrointestinal, and metabolic dysfunctions, as well as pathological pain behaviors. These health concerns are related to the crosstalk between adipose tissue and body systems, leading to pathophysiological changes to the latter. To deal with these health issues, it has been suggested that physical exercise may reverse part of these obesity-related pathologies by modulating the cross talk between the adipose tissue and body systems. In this context, this review was carried out to provide knowledge about (i) the structural and functional changes in tissues, organs, and body systems from accumulation of fat in obesity, emphasizing the crosstalk between fat and body tissues; (ii) the crosstalk between fat and body tissues triggering pain; and (iii) the effects of physical exercise on body tissues and organs in obese and non-obese subjects, and their impact on pathological pain. This information may help one to better understand this crosstalk and the factors involved, and it could be useful in designing more specific training interventions (according to the nature of the comorbidity).

Effectiveness of High-Frequency Transcranial Magnetic Stimulation and Physical Exercise in Women With Fibromyalgia: A Randomized Controlled Trial

OBJECTIVE

Fibromyalgia (FM) is characterized by chronic widespread pain and both physical and emotional alterations, which in turn may affect the individual's quality of life. Thus, interventions aimed at treating such symptoms, without increasing fatigue, are needed. The aim of this study was to explore the effect of high-frequency transcranial magnetic stimulation (HF-TMS) and physical exercise (PE) on pain, impact of FM, physical conditioning, and emotional status in women with FM.

METHODS

Forty-nine women with FM were randomly allocated to: (1) a PE group (PEG, n = 16), who underwent an 8-week (two 60-minute sessions/wk) low-intensity PE program; (2) a TMS group (TMSG, n = 17) receiving a 2-week (five 20-minute sessions/wk) HF-TMS intervention; and (3) a control group (CG, n = 16). Pain (ie, perceived pain and average pressure pain threshold), perceived impact of FM (ie, overall impact, symptoms, and perceived physical function), physical conditioning (ie, endurance and functional capacity, fatigue, gait velocity, and power), and emotional status (ie, anxiety, depression, stress, and satisfaction) were assessed at baseline (T0) and after the intervention (T1, at 2 weeks for TMSG and at 8 weeks for PEG and CG).

RESULTS

The TMSG showed significant improvement in all studied variables after the intervention except for satisfaction, whereas the PEG showed improved average pressure pain threshold, perceived overall impact of FM and total score, endurance and functional capacity, velocity and power, anxiety, depression, and stress. In contrast, the CG showed no improvements in any variable.

CONCLUSION

Both PE and HF-TMS are effective in improving pain, impact of FM, physical conditioning, and emotional status in people with FM; HF-TMS achieved larger improvements in emotional status than PE.

IMPACT

TMS and PE have similar benefits for physical status, whereas TMS has greater benefits than PE for emotional status in women with FM.

Effects of Non-Pharmacological Treatment on Pain, Flexibility, Balance and Quality of Life in Women with Fibromyalgia: A Randomised Clinical Trial

Background: The functional deficits in people with fibromyalgia can be related to the level of physical activity performed. This study investigated the effectiveness of an active exercise programme versus exercise for well-being improving pain, flexibility, static balance, perceived exertion and quality of life of women with fibromyalgia; Methods: A randomised, single-blind, controlled trial was conducted. A total of 141 of women diagnosed with fibromyalgia were enrolled and randomised to an active exercise program group (n = 47), where they performed physical active exercises, an exercise for well-being group (n = 47), which performed the Qi Gong exercises named ‘the twenty Wang Ziping figures for health and longevity’, and a control group (n = 47), which did not receive any intervention, for a period of 4 weeks. Measures were taken at baseline and after the treatment. The primary outcome measures were static balance and centre of gravity (Wii-Fit Nintendo ©), flexibility (test de Wells and Dillon), pain (Visual Analogue Scale) and quality of life (Spanish-Fibromyalgia Impact Questionnaire). The secondary outcome measure was the perceived exertion during activity (BORG Scale). Results: In total, 93 participants completed the study. The mean value of the age was 52.24 ± 6.19. The post intervention results showed statistically significant improvements in the exercise for well-being and the active exercise programme groups vs. the control group in relation to pain (p = 0.006 active exercise programme group, p = 0.001 exercise for well-being group), static balance (p < 0.001 active exercise programme group) and quality of life (p < 0.001 active exercise programme group, p = 0.002 exercise for well-being group). In addition, the mean scores related to perceived fatigue during the sessions were 6.30 ± 1.88 for the active exercise programme group and 5.52 ± 1.55 for the exercise for well-being group. These differences were not significant. Conclusions: The active exercise program and exercise for well-being improved flexibility, static balance, pain and quality of life of women with fibromyalgia. The participants of the active exercise programme achieved better results that those of the exercise for well-being.

Women with Fibromyalgia Prefer Resistance Exercise with Heavy Loads-A Randomized Crossover Pilot Study

Fibromyalgia (FM) is a chronic pain condition associated with impaired muscle strength and exercise-induced pain. Physical exercise has been highlighted, by international clinical guidelines and stakeholders, as an essential component of rehabilitation in FM. Exposure to pain during exercise is generally correlated with elevated lactate levels and, additionally, is one known reason for persons with FM to avoid physical exercise and activity. A crossover design was used to test and evaluate an approach consisting of resistance exercise with heavy loads and a low number of repetitions among ten women with FM. The participants were consecutively recruited to test and perform exercise with two different resistance levels (A = light/moderate load, and B = heavy load) in a randomized crossover trial using an AB/BA setting. Results showed that the heavy load exercise session was experienced as more positive than the light/moderate load exercise session and that lower lactate levels followed exercise with heavier weight loads. This is promising and indicates that the approach of heavy weight loads and accustomed repetitions is accepted in FM and has the potential to attenuate hesitation to exercise due to exercise-induced pain. However, these effects need to be further investigated in more extensive studies.

Juvenile primary fibromyalgia syndrome: A Review- Treatment and Prognosis

Juvenile primary fibromyalgia syndrome (JPFS) is a chronic musculoskeletal pain syndrome affecting children and adolescents. In part one of this review, we discussed the epidemiology, etiology, pathogenesis, clinical manifestations and diagnosis of JPFS. Part two focuses on the treatment and prognosis of JPFS. Early intervention is important. The standard of care is multidisciplinary, combining various modalities-most importantly, exercise and cognitive behavioral therapy. Prognosis varies and symptoms may persist into adulthood.

Is active commuting associated with sedentary behaviour and physical activity in women with fibromyalgia? The al-Ándalus project

PURPOSE

This study aimed to examine the association between active commuting and sedentary time (ST) and physical activity (PA) in women with fibromyalgia.

MATERIALS AND METHODS

This cross-sectional study included 420 women with fibromyalgia (aged 30 to 74 years old) from Spain. The participants wore an accelerometer during seven days to record ST and PA. They also self-reported patterns of active commuting. Linear regression analyses were conducted to examine the relationships between commuting and accelerometer outcomes. Age, pressure pain threshold, and accelerometer wear time were used as confounders.

RESULTS

There was a negative association between active commuting and ST whereas active commuting was positively associated with moderate PA, moderate-to-vigorous PA, total PA, and step count (all p ≤ 0.01). No associations were observed in the older group.

CONCLUSION

Younger women with fibromyalgia who were active commuters spent less ST and were involved in greater PA than passive commuters. This study highlights the importance of promoting active commuting to increase PA among young women with fibromyalgia, while other sources of PA might be recommended for older patients if levels of active commuting are not increased.Implications for rehabilitationActive commuting is a source to increase PA in women with fibromyalgia.Active commuting alone does not seem to be enough to increase PA levels in older women with fibromyalgia and additional PA strategies should be implemented.Promotion of active commuting in young women with fibromyalgia is recommended.

Impact of isometric and concentric resistance exercise on pain and fatigue in fibromyalgia

PURPOSE

The aim of this study was to determine the local and systemic effects of isometric and concentric muscle contractions on experimental pain and performance fatigability in people with and without fibromyalgia.

METHODS

Forty-seven fibromyalgia (FM: 51.3 ± 12.3 year) and 47 control (CON: 52.5 ± 14.7 year) participants performed submaximal isometric and concentric exercise for 10 min with the right elbow flexors. Assessments before and after exercise included pressure pain thresholds (PPT) of the biceps and quadriceps, central pain summation, self-reported exercising arm and whole-body pain, and maximal voluntary isometric contraction (MVIC) of the right elbow flexors and left handgrip.

RESULTS

People with FM experienced greater reductions in local fatigue (right elbow flexor MVIC: CON: - 4.0 ± 6.7%, FM: - 9.8 ± 13.8%; p = 0.013) and similar reductions in systemic fatigue (left handgrip MVIC: - 6.5 ± 10.2%; p < 0.001) as CON participants, which were not different by contraction type nor related to baseline clinical pain, perceived fatigue, or reported pain with exercise. Following exercise both groups reported an increase in PPTs at the biceps (pre: 205.5 ± 100.3 kPa, post: 219.0 ± 109.3 kPa, p = 0.004) only and a decrease in central pain summation (pre: 6.8 ± 2.9, post: 6.5 ± 2.9; p = 0.013). FM reported greater exercising arm pain following exercise (CON: 0.7 ± 1.3, FM: 2.9 ± 2.3; p < 0.001), and both groups reported greater arm pain following concentric (isometric: 1.4 ± 2.0, concentric: 2.2 ± 2.9; p = 0.001) than isometric exercise. Neither group reported an increase in whole-body pain following exercise.

CONCLUSION

People with FM experienced greater performance fatigability in the exercising muscle compared to CON that was not related to central mechanisms of fatigue or pain. These results suggest changes in performance fatigability in FM may be due to differences occurring at the muscular level. TRIAL REGISTRATION #: NCT #: NCT03778385, December 19, 2018, retrospectively registered. IRB#: HR-3035.

What we already know about the effects of exercise in patients with fibromyalgia: An umbrella review

We aimed to analyze the evidence on the effects of physical exercise in patients with fibromyalgia (FM) and to assess the characteristics of published studies, especially the quality of the evidence, through an umbrella review. This umbrella review followed the PRISMA guidelines and was documented in the PROSPERO registry (CRD42017075687). We searched the PubMed, Web of Science, SportDiscus, Scopus, Cinahl, and Cochrane Library databases. The methodological quality of systematic reviews was assessed using AMSTAR 2. We only selected systematic reviews (with or without meta-analyses) investigating the effects of any type of physical exercise in patients with FM syndrome. Thirty-seven systematic reviews (total = 477) fulfilled the criteria. Most studies were rated as being of low or moderate quality. A variety of exercises were used as treatment for FM symptoms, with positive results. Most of the reviews investigated the effects of aerobic exercise and strength training. No serious adverse events were reported. The largest effects of exercise were seen in terms of improved pain intensity and quality of life. Altogether, exercise may be an effective treatment for FM symptoms. Thus, aerobic exercise and strength training are effective programs for the treatment of FM. By summarizing the findings and effect sizes of the reviewed studies, we observed that the evidence for improvement of pain level and quality of life was the strongest. The results have potential to influence evidence-based practice. Future studies should analyze the long-term effects of exercise.

Fibromyalgia: Recent Advances in Diagnosis, Classification, Pharmacotherapy and Alternative Remedies

Fibromyalgia (FM) is a syndrome that does not present a well-defined underlying organic disease. FM is a condition which has been associated with diseases such as infections, diabetes, psychiatric or neurological disorders, rheumatic pathologies, and is a disorder that rather than diagnosis of exclusion requires positive diagnosis. A multidimensional approach is required for the management of FM, including pain management, pharmacological therapies, behavioral therapy, patient education, and exercise. The purpose of this review is to summarize the recent advances in classification criteria and diagnostic criteria for FM as well as to explore pharmacotherapy and the use of alternative therapies including the use of plant bioactive molecules.

Effects of Pain Reduction by Self-Natural Posture Exercise on Affective Complexity in Women: The Moderating Effect of Self-Regulation

This study aimed to investigate the effects of pain reduction and self-regulation efficacy on affective complexity in female patients with chronic pain after participation in an exercise therapy program—Self-Natural Posture Exercise (SNPE)—within the theoretical framework of the Dynamic Model of Affect. A 12-week SNPE program (thrice a week, 70 min per session) was conducted with 101 women with chronic pain lasting longer than 6 months. Pre- versus post-SNPE difference in the correlation between positive affect (PA) and negative affect (NA) was examined through Fisher’s z test, and the moderation effect was confirmed through hierarchical regression analysis. Upon completion of the program, participants experienced pain [M_pre = 5.68 (SD_pre = 1.96) vs. M_post = 3.12 (SD_post = 2.16)] and stress reduction [M_pre = 2.92 (SD_pre = 0.95) vs. M_post = 2.62 (SD_post = 0.86)], higher satisfaction with life [M_pre = 4.25 (SD_pre = 1.20) vs. M_post = 4.80 (SD_post = 1.15)], and decreases in the negative correlation between PA and NA (r_pre = −0.541 vs. r_post = −0.379). Furthermore, participation in the SNPE program neutralized the impact of PA_post on NA_post (β = −0.03) in participants with high self-regulation and pain reduction. These results suggest that self-regulation helps to increase SNPE adherence, which would induce pain reduction and restore affective complexity. Based on the strength model of self-control, to increase the pain reduction through exercise therapy, the instructor should ensure that the participants are not being ego depleted.

Low-Intensity Physical Exercise Improves Pain Catastrophizing and Other Psychological and Physical Aspects in Women with Fibromyalgia: A Randomized Controlled Trial

Fibromyalgia (FM) is a chronic syndrome characterized by widespread pain and other physical and psychological features. In this study, we aimed to analyze the effect of a low-intensity physical exercise (PE) program, combining endurance training and coordination, on psychological aspects (i.e., pain catastrophizing, anxiety, depression, stress), pain perception (i.e., pain acceptance, pressure pain threshold (PPT), and quality of life and physical conditioning (i.e., self-perceived functional capacity, endurance and functional capacity, power and velocity) in women with FM. For this purpose, a randomized controlled trial was carried out. Thirty-two women with FM were randomly allocated to a PE group (PEG, n = 16), performing an eight-week low-intensity PE program and a control group (CG, n = 16). Pain catastrophizing, anxiety, depression, stress, pain acceptance, PPT, quality of life, self-perceived functional capacity, endurance and functional capacity, power, and velocity were assessed before and after the intervention. We observed a significant improvement in all studied variables in the PEG after the intervention (p < 0.05). In contrast, the CG showed no improvements in any variable, which further displayed poorer values for PPT (p < 0.05). In conclusion, a low-intensity combined PE program, including endurance training and coordination, improves psychological variables, pain perception, quality of life, and physical conditioning in women with FM.

"A little bit of a guidance and a little bit of group support": a qualitative study of preferences, barriers, and facilitators to participating in community-based exercise opportunities among adults living with chronic pain

Purpose: To understand preferences, barriers, and facilitators to participating in community-based exercise opportunities among adults living with chronic pain.Materials and Methods: An interpretive description methodology based on semi-structured interviews was conducted. Adults (age>18 years) living with chronic pain (pain >3 months in duration) were recruited from a multidisciplinary chronic pain clinic in Toronto, Canada. Thematic analysis was used to conceptualize interview data.Results: Fifteen adults living with chronic pain (11/15 women) were interviewed. Four themes regarding preferences, barriers, and facilitators to participation in community-based exercise are described: (1) accessibility (e.g., cost, location, scheduling, and access to program information from healthcare providers); (2) intrinsic factors (e.g., pain, mental health, and motivation); (3) social factors (e.g., isolation, participation with people with similar capabilities, and safe environment); and (4) program factors (e.g., tailored to adults living with chronic pain, gentle exercise, group-based, and delivered by an instructor knowledgeable about chronic pain).Conclusions: Participation in community-based exercise opportunities among adults living with chronic pain may be influenced by accessibility, intrinsic factors, social factors, and program factors. Results provide a foundation of understanding to develop person-centered community-based exercise opportunities that are tailored to meet the preferences of this population.Implications for RehabilitationAlthough community-based exercise is commonly recommended as part of ongoing self-management of chronic pain, there is limited research exploring perspectives towards community-based exercise opportunities from the perspective of adults living with chronic pain.Adults living with chronic pain reported specific preferences, barriers, and facilitators to participating in community-based exercise opportunities, including accessibility, instrinsic factors, social factors, and program factors.Most adults living with chronic pain reported a preference for community-based exercise opportunities that: (1) are delivered by an instructor who is knowledgeable about chronic pain; (2) involve gentle exercise; (3) are group-based; and (4) include other individuals with similar physical capabilities.Healthcare providers, community-based organizations, and researchers should develop, implement, and evaluate person-centered community-based exercise opportunities for adults living with chronic pain that consider their unique preferences, barriers, and facilitators to participation.

Promoting Participation in Physical Activity and Exercise Among People Living with Chronic Pain: A Qualitative Study of Strategies Used by People with Pain and Their Recommendations for Health Care Providers

OBJECTIVE

To explore strategies used by people living with chronic pain when participating in physical activity and exercise and their recommendations for health care providers when promoting participation in physical activity and exercise.

DESIGN

Interpretive description qualitative study.

SETTING

Participants were recruited from primary care sites and a hospital-based chronic pain clinic in Kingston, Ontario, Canada.

SUBJECTS

Adults (>18 years of age) who self-identified as experiencing chronic pain (three months' duration) were interviewed.

METHODS

In-depth semistructured interviews were conducted with participants. Interviews were audio-recorded, transcribed verbatim, and reviewed for accuracy by the interviewer. Transcripts were analyzed using thematic analysis. Peer debriefing, reflexivity, and multiple in-person meetings were used to establish trustworthiness.

RESULTS

Sixteen adults (five men, 11 women) with a median age of 53 years were interviewed. Strategies used by people living with chronic pain to participate in physical activity and exercise included 1) finding the motivation, 2) setting up for success, 3) leveraging social support, and 4) managing pain and discomfort during activity. Recommendations for health care providers when promoting participation in physical activity and exercise for people living with chronic pain included 1) the importance of listening, 2) providing tailored advice, 3) being supportive, and 4) making physical activity and exercise programming accessible.

CONCLUSIONS

People living with chronic pain reported using multiple strategies to participate in physical activity and exercise. Recommendations for health care providers centered on the importance of listening and taking a supportive approach when promoting engagement in physical activity and exercise for this population.

Aquatic exercise program-modulated oxidative stress markers in patients with Parkinson's disease

Parkinson’s disease is a neurodegenerative disease. Oxidative stress, i.e., the imbalance between the generation of reactive oxygen species and the antioxidant defense capacity of the body, plays an important role in the pathogenesis of this disease. Physical exercise can regulate oxidative stress. The purpose of this study was to analyze the short- and long-term effects of an aquatic exercise program on oxidative stress levels in patients with Parkinson’s disease. The aquatic exercise program was carried out during 1 month with two sessions per week (1 hour/session). Blood samples were collected at four different time points: pre-intervention, immediately, 48 hours, and 30 days after the first session of aquatic exercise program. Our results revealed that water-based programs modulated antioxidant enzyme activity, increased superoxide dismutase activity, reduced catalase activity, and increased the ratio of superoxide dismutase activity to catalase activity in patients with Parkinson’s disease. Compared with pre-intervention and 48 hours after the first session of aquatic exercise program, superoxide dismutase activity was higher and catalase activity was lower immediately and 30 days after the first session. Our results demonstrated that aquatic exercise program could modulate oxidative stress, mainly by the effect of antioxidant enzyme activity. These results could better help understand the target of oxidative stress in Parkinson’s disease. This study was approved by the Ethics Committee of Centro Universitário Metodista IPA (approval No. 1.373.911) on August 9, 2019 and registered with REBEC (registration number: RBR-6NJ4MK).

Not a Painless Condition: Rheumatological and Musculoskeletal Symptoms in Type 2 Diabetes, and the Implications for Exercise Participation

OBJECTIVES

People with type 2 diabetes (T2D) are more likely to develop a range of rheumatological and musculoskeletal symptoms (RMS), and experience both chronic and widespread pain, compared with the general population. However, these symptoms are not commonly acknowledged by researchers, which hampers our understanding of the impact on this population. Since exercise is a key lifestyle management strategy for T2D and participation levels are typically low, understanding the potential impact of RMS on exercise participation is critical. The aim of this review is to summarise the literature regarding the prevalence and pathophysiology of RMS in T2D, the evidence for the benefits and risks associated with exercise on RMS, and the currently available tools for the reporting of RMS in both research studies and community settings.

METHODS

A narrative review.

RESULTS

There are numerous exercise trials in T2D, but few have sufficiently reported pain-related adverse events and even fewer have investigated the effects of exercise on RMS and chronic pain.

DISCUSSION

Recommendations for future research are provided.

Efficacy of neuromuscular electric stimulation versus aerobic exercise on uraemic restless legs syndrome

Background

The prevalence of restless legs syndrome in haemodialysis patients is approximately ~30%, and it is significantly higher than in the general population. Restless legs syndrome is a sensory-motor disorder with negative effects on sleep and daytime activities that affect personal, family and occupational life. The overall impact of restless legs syndrome on quality of life is comparable to that of chronic and frustrating conditions such as depression and diabetes. The present study was conducted to compare the effect of neuromuscular electric stimulation with aerobic exercise on cases of uraemic restless legs syndrome.

Methods

A total of 60 chronic renal failure patients with uraemic restless legs syndrome aged 20 to 65 years participated in this study. Participants were allocated to receive neuromuscular electric stimulation or aerobic exercises. All participants were evaluated before the first session of treatment and after 3 months, at the end of the treatment. Normal and fast walk gait speed tests and the Five Times Sit-to-Stand Test and 60 second Sit-to-Stand Test were used to assess participants' physical status. The Restless Legs Syndrome Rating Scale was used to determine the level of restless legs syndrome severity.

Results

Neuromuscular electric stimulation resulted in significant improvements in all measures of physical performance and in Restless Legs Syndrome Rating Scale score when compared to baseline. Aerobic exercise produced significant improvements in all tests. At the end of the study, aerobic exercise had greater responses than neuromuscular electric stimulation in all parameters measured except the Five Times Sit-to-Stand Test.

Conclusions

Neuromuscular electrical stimulation may be used as an alternative to aerobic exercise to improve physical performance in cases of less severe restless legs syndrome in those unable or unwilling to participate in physical training.

Flexibility exercise training for adults with fibromyalgia

BACKGROUND

Exercise training is commonly recommended for adults with fibromyalgia. We defined flexibility exercise training programs as those involving movements of a joint or a series of joints, through complete range of motion, thus targeting major muscle-tendon units. This review is one of a series of reviews updating the first review published in 2002.

OBJECTIVES

To evaluate the benefits and harms of flexibility exercise training in adults with fibromyalgia.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), PEDro (Physiotherapy Evidence Database), Thesis and Dissertation Abstracts, AMED (Allied and Complementary Medicine Database), the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), and ClinicalTrials.gov up to December 2017, unrestricted by language, and we reviewed the reference lists of retrieved trials to identify potentially relevant trials.

SELECTION CRITERIA

We included randomized trials (RCTs) including adults diagnosed with fibromyalgia based on published criteria. Major outcomes were health-related quality of life (HRQoL), pain intensity, stiffness, fatigue, physical function, trial withdrawals, and adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected articles for inclusion, extracted data, performed 'Risk of bias' assessments, and assessed the certainty of the body of evidence for major outcomes using the GRADE approach. All discrepancies were rechecked, and consensus was achieved by discussion.

MAIN RESULTS

We included 12 RCTs (743 people). Among these RCTs, flexibility exercise training was compared to an untreated control group, land-based aerobic training, resistance training, or other interventions (i.e. Tai Chi, Pilates, aquatic biodanza, friction massage, medications). Studies were at risk of selection, performance, and detection bias (due to lack of adequate randomization and allocation concealment, lack of participant or personnel blinding, and lack of blinding for self-reported outcomes). With the exception of withdrawals and adverse events, major outcomes were self-reported and were expressed on a 0-to-100 scale (lower values are best, negative mean differences (MDs) indicate improvement). We prioritized the findings of flexibility exercise training compared to land-based aerobic training and present them fully here.Very low-certainty evidence showed that compared with land-based aerobic training, flexibility exercise training (five trials with 266 participants) provides no clinically important benefits with regard to HRQoL, pain intensity, fatigue, stiffness, and physical function. Low-certainty evidence showed no difference between these groups for withdrawals at completion of the intervention (8 to 20 weeks).Mean HRQoL assessed on the Fibromyalgia Impact Questionnaire (FIQ) Total scale (0 to 100, higher scores indicating worse HRQoL) was 46 mm and 42 mm in the flexibility and aerobic groups, respectively (2 studies, 193 participants); absolute change was 4% worse (6% better to 14% worse), and relative change was 7.5% worse (10.5% better to 25.5% worse) in the flexibility group. Mean pain was 57 mm and 52 mm in the flexibility and aerobic groups, respectively (5 studies, 266 participants); absolute change was 5% worse (1% better to 11% worse), and relative change was 6.7% worse (2% better to 15.4% worse). Mean fatigue was 67 mm and 71 mm in the aerobic and flexibility groups, respectively (2 studies, 75 participants); absolute change was 4% better (13% better to 5% worse), and relative change was 6% better (19.4% better to 7.4% worse). Mean physical function was 23 points and 17 points in the flexibility and aerobic groups, respectively (1 study, 60 participants); absolute change was 6% worse (4% better to 16% worse), and relative change was 14% worse (9.1% better to 37.1% worse). We found very low-certainty evidence of an effect for stiffness. Mean stiffness was 49 mm to 79 mm in the flexibility and aerobic groups, respectively (1 study, 15 participants); absolute change was 30% better (8% better to 51% better), and relative change was 39% better (10% better to 68% better). We found no evidence of an effect in all-cause withdrawal between the flexibility and aerobic groups (5 studies, 301 participants). Absolute change was 1% fewer withdrawals in the flexibility group (8% fewer to 21% more), and relative change in the flexibility group compared to the aerobic training intervention group was 3% fewer (39% fewer to 55% more). It is uncertain whether flexibility leads to long-term effects (36 weeks after a 12-week intervention), as the evidence was of low certainty and was derived from a single trial.Very low-certainty evidence indicates uncertainty in the risk of adverse events for flexibility exercise training. One adverse effect was described among the 132 participants allocated to flexibility training. One participant had tendinitis of the Achilles tendon (McCain 1988), but it is unclear if the tendinitis was a pre-existing condition.

AUTHORS' CONCLUSIONS

When compared with aerobic training, it is uncertain whether flexibility improves outcomes such as HRQoL, pain intensity, fatigue, stiffness, and physical function, as the certainty of the evidence is very low. Flexibility exercise training may lead to little or no difference for all-cause withdrawals. It is also uncertain whether flexibility exercise training has long-term effects due to the very low certainty of the evidence. We downgraded the evidence owing to the small number of trials and participants across trials, as well as due to issues related to unclear and high risk of bias (selection, performance, and detection biases). While flexibility exercise training appears to be well tolerated (similar withdrawal rates across groups), evidence on adverse events was scarce, therefore its safety is uncertain.

Differences in long-term physical activity trajectories among individuals with chronic widespread pain: A secondary analysis of a randomized controlled trial

BACKGROUND

Little is known about long-term physical activity (PA) maintenance in those with chronic widespread pain (CWP) following an exercise intervention. This study examined PA over time to identify the existence and characteristics of subgroups following distinct PA trajectories.

METHODS

Data come from individuals with CWP who took part in a 2 × 2 factorial randomized controlled trial, receiving either exercise or both exercise and cognitive behavioural therapy treatment. Information, including self-report PA, was collected at baseline recruitment, immediately post-intervention, 3, 24 and 60+ month post-treatment. Analyses were conducted on 196 men and women with ≥ 3 PA data points. Group-based trajectory modelling was used to identify latent PA trajectory groups and baseline characteristics (e.g., demographics, pain, self-rated health, fatigue, coping-strategy use and kinesiophobia) of these groups.

RESULTS

The best fitting model identified was one with three trajectories: "non-engagers" (n = 32), "maintainers" (n = 144) and "super-maintainers" (n = 20). Overall, mean baseline PA levels were significantly different between groups (non-engagers: 1.1; maintainers: 4.6; super-maintainers: 8.6, p < 0.001) and all other follow-up points. Non-engagers reported, on average, greater BMI, higher disabling chronic pain, poorer self-rated health, physical functioning, as well as greater use of passive coping strategies and lower use of active coping strategies.

CONCLUSIONS

The majority of individuals with CWP receiving exercise as part of a trial were identified as long-term PA maintainers. Participants with poorer physical health and coping response to symptoms were identified as non-engagers. For optimal symptom management, a stratified approach may enhance initiation and long-term PA maintenance in individuals with CWP.

SIGNIFICANCE

Chronic pain can be a major barrier to engaging in exercise, a popular self-management strategy. Our findings identify three distinct long-term physical activity trajectories for individuals receiving the same exercise intervention. This suggests an approach by health care providers which identifies individuals who would benefit from additional support to enhance initiation and long-term physical activity maintenance could deliver better outcomes for such patients.

The treatment of central sensitization in an adolescent using pain neuroscience education and graded exposure to activity: A case report

Chronic pain affects 1.7 million children in the United States, and its effects often linger into adulthood. Unfortunately, chronic pediatric pain is often undertreated. The current case report discusses the use of pain neuroscience education (PNE) combined with progressive exposure to activity to treat persistent pain in a 13-year-old female diagnosed with central sensitization syndrome. Prior to the diagnosis, the patient underwent two unsuccessful episodes of physical therapy that focused on musculoskeletal sources of pain. The patient was then referred to a physical therapist specializing in pain management. Following a detailed evaluation, PNE and graded exposure were used over a 4-week period to address the patient's condition and her behavioral responses to it. Significant decreases were observed in lowest (67%) and usual (50%) pain ratings and the portion of the day her worst pain was felt (67%), while the portion of the day with bearable pain (80%). Significant improvements in her ability to dance (168%), hike (50%), and run (200%) were observed. Reconceptualizing pain and its meaning changed perceptions and behaviors, allowing improvement when other approaches failed. Although effective for this patient, more research is needed into the use of this approach in the treatment of chronic pediatric pain.

The effect of cryotherapy on fibromyalgia: a randomised clinical trial carried out in a cryosauna cabin

Evidence of symptomatic treatment for fibromyalgia (FM) is very low. Whole body cryotherapy (WBC) modulates different neurotransmitters, which might have a role in pain alleviation and could exert an effect on FM. Our aim was to evaluate the efficacy of WBC for the control of pain and impact of disease in FM. For this we run an open, randomized, crossover trial of Cryosense TCT™ cabin vs rest. Patients with FM according to ACR criteria were recruited consecutively from general practices. Trial endpoints were change (∆) in pain after 2 and 4 weeks, measured by a visual analogue scale (VAS), ∆ burden of disease, evaluated by the Fibromyalgia Impact Questionnaire (FIQ), and severity of FM, measured by the Combined Index of Severity of Fibromyalgia (ICAF). Within group differences, sequence and period effects were tested with Student's t or Mann-Whitney U tests. Multiple linear regression models were used to adjust effect by baseline differences between groups. Sixty patients were included in the trial. A period effect was noted, with residual effect of WBC; therefore, only results from the first sequence were analysed. ∆VAS pain, ∆FIQ and ∆ICAF scores were significantly larger in the WBC group after the first period (3.0 vs 0.3 in ∆VAS pain; 32.1 vs 0.4 in ∆FIQ; 13.7 vs 0.07 in ∆ICAF; all p < 0.001), and were confirmed after adjustment. In conclusion, WBC with a Cryosense TCT cabin may be a useful adjuvant therapy for FM; further studies on long-term effect and compared to other physical therapies are warranted.Trial registration NCT03425903.

Impact of a socio-educational intervention to improve the quality of life of patients with fibromyalgia: A quasi-experimental design

OBJECTIVE

To evaluate the impact of a socio-educational intervention to improve the quality of life of patients with fibromyalgia.

METHOD

Out of 132 eligible candidates, 128 patients participated with a diagnosis of fibromyalgia (ACR 1990/2010), over 18 years of age, who did not have cognitive problems or mental disorders in acute phase and lived in the catchment area of the participating CAPs. The patients underwent intervention for 5 weeks to strengthen self-management of pain and improve quality of life. Socio-demographic variables, satisfaction and quality of life (SF-36) were studied. Pre-post measurements were made on the 128 participants and follow-up at 2 months on 120 (8 did not agree to be contacted).

RESULTS

Comparing the pre-post-intervention scores (non-parametric Wilcoxon test), it was found that 71.09% reported a higher perception of quality of life in the Mental health domain and lower percentage of improvement (28.91%) in the Physical role domain. When comparing pre-post-follow-up scores (Friedman's test), mean perception improved in all domains and remained at 2-month follow-up (P<.001). Finally, the average satisfaction with the intervention received was 90.55% (SD 9.86; min. 41, max. 100).

CONCLUSIONS

When assessing the impact of the intervention, there was an improvement in the post and follow-up scores. This finding is largely due to the fact that the intervention strengthens the patient's self-mastery of their abilities to control pain and improve their perception of quality of life.

Unravelling Fibromyalgia-Steps Toward Individualized Management

The heterogeneity of the clinical presentation and the pathophysiologic mechanisms associated with fibromyalgia (FM), and the modest results on average for any therapy, call for a more individualized management strategy. Individualized treatment can be on the basis of subgrouping of patients according to associated conditions (mental health problems, chronic overlapping pain conditions, other somatic diseases) or on disease severity. Categorizing FM as mild, moderate, or severe can be on the basis of clinical assessment (eg, degree of daily functioning) or on questionnaires. Shared decision-making regarding treatment options can be directed according to patient preferences, comorbidities, and availability in various health care settings. The European League Against Rheumatism guidelines recommend a tailored approach directed by FM key symptoms (pain, sleep disorders, fatigue, depression, disability), whereas the German guidelines recommend management tailored to disease severity, with mild disease not requiring any specific treatment, and more severe disease requiring multicomponent therapy (combination of drug treatment with aerobic exercise and psychological treatments). When indicated, treatments should follow a stepwise approach beginning with easily available therapies such as aerobic exercise and amitriptyline. Successful application of a tailored treatment approach that is informed by individual patient characteristics should improve outcome of FM.

PERSPECTIVE

This article presents suggestions for an individualized treatment strategy for FM patients on the basis of subgroups and disease severity. Categorizing FM as mild, moderate, or severe can be on the basis of clinical assessment (eg, degree of daily functioning) or questionnaires. Subgroups can be defined according to mental health and somatic comorbidities.

Fibromyalgia: Treating Pain in the Juvenile Patient

Presently, evidence for the efficacy of medications for the treatment of juvenile fibromyalgia syndrome (JFMS) is limited. While there are medications approved by the US Food and Drug Administration (duloxetine, milnacipran and pregabalin) for adults with fibromyalgia syndrome, there are none for the treatment of JFMS. A variety of medications have been prescribed for the treatment of JFMS, including (but not limited to) non-opioid analgesics, opioids, anticonvulsants, antidepressants, and muscle relaxants. Psychological therapies, most prominently cognitive behavioral therapy, are the most evidenced-based treatment modalities for JFMS. A multidisciplinary approach, combining pharmacological, behavioral and exercise-based modalities is currently the standard of care for JFMS. In the future, more stringent randomized, controlled trials with longer follow-up periods are needed in order to determine the long-term efficacy and safety of medications in the treatment of JFMS. Additionally, improved recognition of JFMS will allow for better patient recruitment to permit for adequately powered study designs.

Exercise for chronic musculoskeletal pain: A biopsychosocial approach

Chronic musculoskeletal pain (CMP) refers to ongoing pain felt in the bones, joints and tissues of the body that persists longer than 3 months. For these conditions, it is widely accepted that secondary pathologies or the consequences of persistent pain, including fear of movement, pain catastrophizing, anxiety and nervous system sensitization appear to be the main contributors to pain and disability. While exercise is a primary treatment modality for CMP, the intent is often to improve physical function with less attention to secondary pathologies. Exercise interventions for CMP which address secondary pathologies align with contemporary pain rehabilitation practices and have greater potential to improve patient outcomes above exercise alone. Biopsychosocial treatment which acknowledges and addresses the biological, psychological and social contributions to pain and disability is currently seen as the most efficacious approach to chronic pain. This clinical update discusses key aspects of a biopsychosocial approach concerning exercise prescription for CMP and considers both patient needs and clinician competencies. There is consensus for individualized, supervised exercise based on patient presentation, goals and preference that is perceived as safe and non-threatening to avoid fostering unhelpful associations between physical activity and pain. The weight of evidence supporting exercise for CMP has been provided by aerobic and resistance exercise studies, although there is considerable uncertainty on how to best apply the findings to exercise prescription. In this clinical update, we also provide evidence-based guidance on exercise prescription for CMP through a synthesis of published work within the field of exercise and CMP rehabilitation.

Lumbopelvic Core Stabilization Exercise and Pain Modulation Among Individuals with Chronic Nonspecific Low Back Pain

BACKGROUND

Lumbopelvic stabilization training (LPST) may provide therapeutic benefits on pain modulation in chronic nonspecific low back pain conditions. This study aimed to examine the effects of LPST on pain threshold and pain intensity in comparison with the passive automated cycling intervention and control intervention among patients with chronic nonspecific low back pain.

METHODS

A within-subject, repeated-measures, crossover randomized controlled design was conducted among 25 participants (7 males and 18 females) with chronic nonspecific low back pain. All the participants received 3 different types of experimental interventions, which included LPST, the passive automated cycling intervention, and the control intervention randomly, with 48 hours between the sessions. The pressure pain threshold (PPT), hot-cold pain threshold, and pain intensity were estimated before and after the interventions.

RESULTS

Repeated-measures analysis of variance showed that LPST provided therapeutic effects as it improved the PPT beyond the placebo and control interventions (P < 0.01). The pain intensity under the LPST condition was significantly better than that under the passive automated cycling intervention and controlled intervention (P < 0.001). Heat pain threshold under the LPST condition also showed a significant trend of improvement beyond the control (P < 0.05), but no significant effects on cold pain threshold were evident.

CONCLUSIONS

Lumbopelvic stabilization training may provide therapeutic effects by inducing pain modulation through an improvement in the pain threshold and reduction in pain intensity. LPST may be considered as part of the management programs for treatment of chronic low back pain.

Management of fibromyalgia syndrome in 2016

Fibromyalgia syndrome is a chronic pain disorder and defies definitively efficacious therapy. In this review, we summarize the results from the early treatment research as well as recent research evaluating the pharmacological, interventional and nonpharmacological therapies. We further discuss future directions of fibromyalgia syndrome management; we specifically focus on the issues that are associated with currently available treatments, such as the need for personalized approach, new technologically oriented and interventional treatments, the importance of understanding and harnessing placebo effects and enhancement of patient engagement in therapy.

Physical exercise as non-pharmacological treatment of chronic pain: Why and when

Chronic pain broadly encompasses both objectively defined conditions and idiopathic conditions that lack physical findings. Despite variance in origin or pathogenesis, these conditions are similarly characterized by chronic pain, poor physical function, mobility limitations, depression, anxiety, and sleep disturbance, and they are treated alone or in combination by pharmacologic and non-pharmacologic approaches, such as physical activity (aerobic conditioning, muscle strengthening, flexibility training, and movement therapies). Physical activity improves general health, disease risk, and progression of chronic illnesses such as cardiovascular disease, type 2 diabetes, and obesity. When applied to chronic pain conditions within appropriate parameters (frequency, duration, and intensity), physical activity significantly improves pain and related symptoms. For chronic pain, strict guidelines for physical activity are lacking, but frequent movement is preferable to sedentary behavior. This gives considerable freedom in prescribing physical activity treatments, which are most successful when tailored individually, progressed slowly, and account for physical limitations, psychosocial needs, and available resources.

Does increasing steps per day predict improvement in physical function and pain interference in adults with fibromyalgia?

OBJECTIVE

To examine the concurrent and predictive associations between the number of steps taken per day and clinical outcomes in patients with fibromyalgia (FM).

METHODS

A total of 199 adults with FM (mean age 46.1 years, 95% women) who were enrolled in a randomized clinical trial wore a hip-mounted accelerometer for 1 week and completed self-report measures of physical function (Fibromyalgia Impact Questionnaire-Physical Impairment [FIQ-PI], Short Form 36 [SF-36] health survey physical component score [PCS], pain intensity and interference (Brief Pain Inventory [BPI]), and depressive symptoms (Patient Health Questionnaire-8 [PHQ-8]) as part of their baseline and followup assessments. Associations of steps per day with self-report clinical measures were evaluated from baseline to week 12 using multivariate regression models adjusted for demographic and baseline covariates.

RESULTS

Study participants were primarily sedentary, averaging 4,019 ± 1,530 steps per day. Our findings demonstrate a linear relationship between the change in steps per day and improvement in health outcomes for FM. Incremental increases on the order of 1,000 steps per day were significantly associated with (and predictive of) improvements in FIQ-PI, SF-36 PCS, BPI pain interference, and PHQ-8 (all P < 0.05). Although higher step counts were associated with lower FIQ and BPI pain intensity scores, these were not statistically significant.

CONCLUSION

Step count is an easily obtained and understood objective measure of daily physical activity. An exercise prescription that includes recommendations to gradually accumulate at least 5,000 additional steps per day may result in clinically significant improvements in outcomes relevant to patients with FM. Future studies are needed to elucidate the dose-response relationship between steps per day and patient outcomes in FM.

Evaluation of the effectiveness of an aerobic exercise program and the personality characteristics of patients with fibromyalgia syndrome: a pilot study

[Purpose] The aim of this study was to assess the effectiveness of a 6-week aerobic exercise program on pain, physical function, and psychological status, and to evaluate the personality characteristics of fibromyalgia syndrome (FMS) patients. [Subjects and Methods] Fourteen women with FMS were enrolled. They were trained for a 6-week home-based aerobic exercise program. The Fibromyalgia Impact Questionnaire, the Beck Depression Inventory, the visual analog scale of pain and sleep quality were measured at baseline and at the end of week 6. The personality profiles were evaluated using the Minnesota Multiphasic Personality Inventory (MMPI). [Results] After the exercise program, significant improvements were determined in pain, sleep quality, physical function, depression and FMS symptoms compared to baseline. In addition, the hysteria item (71.21±8.84) of the MMPI was significantly higher in FMS. [Conclusion] Our findings indicate that home-based aerobic exercise may be a useful treatment in the management of FMS. Personality characteristics should be considered during the planning process of the treatment of FMS. Personality is a filter between life events and psychological responses. It is defined to be the integration of effective and behavioral patterns. Long-term studies involving larger clinical samples are needed to define the role of personality characteristics in FMS.

Preliminary evidence of a blunted anti-inflammatory response to exhaustive exercise in fibromyalgia

Exercise intolerance, as evidenced by a worsening of pain, fatigue, and stiffness after novel exertion, is a key feature of fibromyalgia (FM). In this pilot study, we investigate whether; insufficient muscle repair processes and impaired anti-inflammatory mechanisms result in an exaggerated pro-inflammatory cytokine response to exhaustive exercise, and consequently a worsening of muscle pain, stiffness and fatigue in the days post-exercise. We measured changes in muscle pain and tenderness, fatigue, stiffness, and serum levels of neuroendocrine and inflammatory cytokine markers in 20 women with FM and 16 healthy controls (HCs) before and after exhaustive treadmill exercise. Compared to HCs, FM participants failed to mount the expected anti-inflammatory response to exercise and experienced a worsening of symptoms post-exercise. However, changes in post-exertional symptoms were not mediated by post-exertional changes in pro-inflammatory cytokine levels. Implications of these findings are discussed.

A systematic review of studies using pedometers as an intervention for musculoskeletal diseases

Background

Physical activity (PA) plays an important role in the prevention and management of a number of chronic conditions. Aim: to investigate the evidence for effectiveness of pedometer-driven walking programs to promote physical activity among patients with musculoskeletal disorders (MSDs).

Method

A comprehensive systematic review was performed using 11 electronic databases up to 20 February 2014. Keywords and MeSH terms included “musculoskeletal disorders”, “walking”, and “pedometer”. Randomized controlled trials, published in English, that examined the effects of a pedometer-based walking intervention to increase physical activity levels and improve physical function and pain in patients with musculoskeletal disorders were included.

Result

Of the 1996 articles retrieved, seven studies ranging in date of publication from 1998 to 2013 met the inclusion criteria, allowing data extraction on 484 participants with an age range of 40 to 82 years. Interventions lasted from 4 weeks to 12 months and the results across studies showed significant increases in step count (p < 0.05) following the intervention. Across these studies, there was a mean increase in PA of 1950 steps per day relative to baseline. Four studies reported improved scores for pain and/or physical function at the intervention completion point relative to controls.

Conclusion

This study provides strong evidence for the effectiveness of pedometer walking interventions in increasing PA levels for patients with MSDs. Our findings suggest that a combination of interventions is likely to be the most effective strategy to maximize health benefits in the short term. Further research should include larger sample sizes, and longer intervention durations are required to support the role of pedometer walking interventions as a long term intervention for management of musculoskeletal disorders.

Juvenile fibromyalgia: current status of research and future developments

Juvenile-onset fibromyalgia (JFM) is a poorly understood chronic pain condition most commonly affecting adolescent girls. The condition is characterized by widespread musculoskeletal pain and other associated symptoms, including fatigue, nonrestorative sleep, headaches, irritable bowel symptoms, dysautonomia and mood disorders such as anxiety and/or depression. In the past few years, there has been a greater focus on understanding JFM in adolescents. Research studies have provided insight into the clinical characteristics of this condition and its effect on both short-term and long-term psychosocial and physical functioning. The importance of early and effective intervention is being recognized, as research has shown that symptoms of JFM tend to persist and do not resolve over time as was previously believed. Efforts to improve treatments for JFM are underway, and new evidence strongly points to the potential benefits of cognitive-behavioural therapy on improving mood and daily functioning. Research into pharmacotherapy and other nonpharmacological options is in progress. Advancements in the understanding of adult fibromyalgia have paved the way for future studies on diagnosis, assessment and management of JFM.

Interest in yoga among fibromyalgia patients: an international internet survey

Studies in circumscribed clinical settings have reported the adoption of yoga by many fibromyalgia (FM) patients. However, it is unclear from existing studies which types of yoga practices FM patients are typically engaging in and the extent to which they experience yoga as helpful or not. The purpose of this study was to survey FM patients in many different regions to inquire about their engagement in various yoga practices, the perceived benefits, and the obstacles to further practice. A 13-question Internet survey of persons self-identified as FM patients was conducted among subscribers to 2 electronic newsletters on the topic of FM. Respondents (N = 2543) replied from all 50 U.S. states and also from Canada, Australia, and the United Kingdom, and from more than two dozen other countries. On average, respondents were 57 years of age and 96% were female, with an average time since diagnosis of 13 years. Of these respondents, 79.8% had considered trying yoga and 57.8% had attended 1 yoga class. The respondents' classes typically focused almost exclusively on yoga poses, with minimal training in meditation, breathing techniques, or other practices. The most commonly cited benefits were reduced stiffness, relaxation, and better balance. The most frequently cited obstacles were concerns about the poses being too physically demanding and fear that the poses would cause too much pain. These findings confirm strong interest in yoga across a geographically diverse range of FM patients. However, concerns about yoga-induced pain and yoga poses being too difficult are common reasons that FM patients do not engage in yoga exercises. This study supports the need for yoga programs tailored for FM patients to include modification of poses to minimize aggravating movements and substantive training in meditation and other yoga-based coping methods to minimize pain-related fear.
