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.

Mixed exercise training for adults with fibromyalgia.

BACKGROUND: Exercise training is commonly recommended for individuals with fibromyalgia. This review is one of a series of reviews about exercise training for fibromyalgia that will replace the review titled "Exercise for treating fibromyalgia syndrome", which was first published in 2002. OBJECTIVES: To evaluate the benefits and harms of mixed exercise training protocols that include two or more types of exercise (aerobic, resistance, flexibility) for adults with fibromyalgia against control (treatment as usual, wait list control), non exercise (e.g. biofeedback), or other exercise (e.g. mixed versus flexibility) interventions.Specific comparisons involving mixed exercise versus other exercises (e.g. resistance, aquatic, aerobic, flexibility, and whole body vibration exercises) were not assessed. SEARCH METHODS: We searched the Cochrane Library, MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Thesis and Dissertations Abstracts, the Allied and Complementary Medicine Database (AMED), the Physiotherapy Evidence Databese (PEDro), Current Controlled Trials (to 2013), WHO ICTRP, and ClinicalTrials.gov up to December 2017, unrestricted by language, to identify all potentially relevant trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in adults with a diagnosis of fibromyalgia that compared mixed exercise interventions with other or no exercise interventions. Major outcomes were health-related quality of life (HRQL), pain, stiffness, fatigue, physical function, withdrawals, and adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, extracted data, and assessed risk of bias and the quality of evidence for major outcomes using the GRADE approach. MAIN RESULTS: We included 29 RCTs (2088 participants; 98% female; average age 51 years) that compared mixed exercise interventions (including at least two of the following: aerobic or cardiorespiratory, resistance or muscle strengthening exercise, and flexibility exercise) versus control (e.g. wait list), non-exercise (e.g. biofeedback), and other exercise interventions. Design flaws across studies led to selection, performance, detection, and selective reporting biases. We prioritised the findings of mixed exercise compared to control and present them fully here.Twenty-one trials (1253 participants) provided moderate-quality evidence for all major outcomes but stiffness (low quality). With the exception of withdrawals and adverse events, major outcome measures were self-reported and expressed on a 0 to 100 scale (lower values are best, negative mean differences (MDs) indicate improvement; we used a clinically important difference between groups of 15% relative difference). Results for mixed exercise versus control show that mean HRQL was 56 and 49 in the control and exercise groups, respectively (13 studies; 610 participants) with absolute improvement of 7% (3% better to 11% better) and relative improvement of 12% (6% better to 18% better). Mean pain was 58.6 and 53 in the control and exercise groups, respectively (15 studies; 832 participants) with absolute improvement of 5% (1% better to 9% better) and relative improvement of 9% (3% better to 15% better). Mean fatigue was 72 and 59 points in the control and exercise groups, respectively (1 study; 493 participants) with absolute improvement of 13% (8% better to 18% better) and relative improvement of 18% (11% better to 24% better). Mean stiffness was 68 and 61 in the control and exercise groups, respectively (5 studies; 261 participants) with absolute improvement of 7% (1% better to 12% better) and relative improvement of 9% (1% better to 17% better). Mean physical function was 49 and 38 in the control and exercise groups, respectively (9 studies; 477 participants) with absolute improvement of 11% (7% better to 15% better) and relative improvement of 22% (14% better to 30% better). Pooled analysis resulted in a moderate-quality risk ratio for all-cause withdrawals with similar rates across groups (11 per 100 and 12 per 100 in the control and intervention groups, respectively) (19 studies; 1065 participants; risk ratio (RR) 1.02, 95% confidence interval (CI) 0.69 to 1.51) with an absolute change of 1% (3% fewer to 5% more) and a relative change of 11% (28% fewer to 47% more). Across all 21 studies, no injuries or other adverse events were reported; however some participants experienced increased fibromyalgia symptoms (pain, soreness, or tiredness) during or after exercise. However due to low event rates, we are uncertain of the precise risks with exercise. Mixed exercise may improve HRQL and physical function and may decrease pain and fatigue; all-cause withdrawal was similar across groups, and mixed exercises may slightly reduce stiffness. For fatigue, physical function, HRQL, and stiffness, we cannot rule in or out a clinically relevant change, as the confidence intervals include both clinically important and unimportant effects.We found very low-quality evidence on long-term effects. In eight trials, HRQL, fatigue, and physical function improvement persisted at 6 to 52 or more weeks post intervention but improvements in stiffness and pain did not persist. Withdrawals and adverse events were not measured.It is uncertain whether mixed versus other non-exercise or other exercise interventions improve HRQL and physical function or decrease symptoms because the quality of evidence was very low. The interventions were heterogeneous, and results were often based on small single studies. Adverse events with these interventions were not measured, and thus uncertainty surrounds the risk of adverse events. AUTHORS' CONCLUSIONS: Compared to control, moderate-quality evidence indicates that mixed exercise probably improves HRQL, physical function, and fatigue, but this improvement may be small and clinically unimportant for some participants; physical function shows improvement in all participants. Withdrawal was similar across groups. Low-quality evidence suggests that mixed exercise may slightly improve stiffness. Very low-quality evidence indicates that we are 'uncertain' whether the long-term effects of mixed exercise are maintained for all outcomes; all-cause withdrawals and adverse events were not measured. Compared to other exercise or non-exercise interventions, we are uncertain about the effects of mixed exercise because we found only very low-quality evidence obtained from small, very heterogeneous trials. Although mixed exercise appears to be well tolerated (similar withdrawal rates across groups), evidence on adverse events is scarce, so we are uncertain about its safety. We downgraded the evidence from these trials due to imprecision (small trials), selection bias (e.g. allocation), blinding of participants and care providers or outcome assessors, and selective reporting.

Scoping Review of Dance for Adults With Fibromyalgia: What Do We Know About It?

BACKGROUND: Fibromyalgia is a chronic disorder characterized by widespread muscular tenderness, pain, fatigue, and cognitive difficulties. Nonpharmacological treatment options, such as physical activity, are important for people with fibromyalgia. There are strong recommendations to support engagement in physical activity for symptom management among adults with fibromyalgia. Dance is a mode of physical activity that may allow individuals with fibromyalgia to improve their physical function, health, and well-being. Dance has the potential to promote improved pain processing while simultaneously providing the health and social benefits of engaging in physical activity that contributes to symptom management and overall function rehabilitation. However, we are unaware of current evidence on dance as a nonpharmacological/physical activity intervention for adults with fibromyalgia. OBJECTIVE: The aims of this study were to understand how dance is used therapeutically by individuals with fibromyalgia; to examine the extent, range and nature of research activity in the area; and to determine the value of undertaking a systematic review of interventions. METHODS: We used and adapted the Arksey and O'Malley scoping framework. The search strategy involved a comprehensive search of main health and electronic social databases, trial registries and grey literature without language limits. Pairs of reviewers independently screened and extracted data and evaluated the methodological quality of randomized control trials. RESULTS: Twenty-one unique records for 13 studies met inclusion criteria; the studies included mostly middle-aged women. Types of dance included were aerobic dance, belly dance, dance movement therapy, biodanza and Zumba. Intervention parameters were different among studies. Frequency varied between one to three times a week; all were done in small group settings. Studies evaluated a variety of outcomes in the symptoms, wellness, psychosocial, physical functioning, balance and fitness categories; no studies evaluated the safety or adverse events systematically which is a major weakness of the literature. CONCLUSIONS: There are few studies in the field of dance and fibromyalgia, suggesting research is in its infancy but slowly growing. They are of European and South American origin, focusing on female participants and a limited number of dance modes. Because the body of literature is small, of low quality and highly heterogeneous, we concluded that a systematic review of interventions on dance is not warranted at this time.

Aerobic exercise training for adults with fibromyalgia.

BACKGROUND: Exercise training is commonly recommended for individuals with fibromyalgia. This review is one of a series of reviews about exercise training for people with fibromyalgia that will replace the "Exercise for treating fibromyalgia syndrome" review first published in 2002. OBJECTIVES: • To evaluate the benefits and harms of aerobic exercise training for adults with fibromyalgia• To assess the following specific comparisons ० Aerobic versus control conditions (eg, treatment as usual, wait list control, physical activity as usual) ० Aerobic versus aerobic interventions (eg, running vs brisk walking) ० Aerobic versus non-exercise interventions (eg, medications, education) We did not assess specific comparisons involving aerobic exercise versus other exercise interventions (eg, resistance exercise, aquatic exercise, flexibility exercise, mixed exercise). Other systematic reviews have examined or will examine these comparisons (Bidonde 2014; Busch 2013). SEARCH METHODS: We searched the Cochrane Library, MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Physiotherapy Evidence Database (PEDro), Thesis and Dissertation Abstracts, the Allied and Complementary Medicine Database (AMED), the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), and the ClinicalTrials.gov registry up to June 2016, unrestricted by language, and we reviewed the reference lists of retrieved trials to identify potentially relevant trials. SELECTION CRITERIA: We included randomized controlled trials (RCTs) in adults with a diagnosis of fibromyalgia that compared aerobic training interventions (dynamic physical activity that increases breathing and heart rate to submaximal levels for a prolonged period) versus no exercise or another intervention. Major outcomes were health-related quality of life (HRQL), pain intensity, stiffness, fatigue, physical function, withdrawals, and adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, extracted data, performed a risk of bias assessment, and assessed the quality of the body of evidence for major outcomes using the GRADE approach. We used a 15% threshold for calculation of clinically relevant differences between groups. MAIN RESULTS: We included 13 RCTs (839 people). Studies were at risk of selection, performance, and detection bias (owing to lack of blinding for self-reported outcomes) and had low risk of attrition and reporting bias. We prioritized the findings when aerobic exercise was compared with no exercise control and present them fully here.Eight trials (with 456 participants) provided low-quality evidence for pain intensity, fatigue, stiffness, and physical function; and moderate-quality evidence for withdrawals and HRQL at completion of the intervention (6 to 24 weeks). With the exception of withdrawals and adverse events, major outcome measures were self-reported and were expressed on a 0 to 100 scale (lower values are best, negative mean differences (MDs)/standardized mean differences (SMDs) indicate improvement). Effects for aerobic exercise versus control were as follows: HRQL: mean 56.08; five studies; N = 372; MD -7.89, 95% CI -13.23 to -2.55; absolute improvement of 8% (3% to 13%) and relative improvement of 15% (5% to 24%); pain intensity: mean 65.31; six studies; N = 351; MD -11.06, 95% CI -18.34 to -3.77; absolute improvement of 11% (95% CI 4% to 18%) and relative improvement of 18% (7% to 30%); stiffness: mean 69; one study; N = 143; MD -7.96, 95% CI -14.95 to -0.97; absolute difference in improvement of 8% (1% to 15%) and relative change in improvement of 11.4% (21.4% to 1.4%); physical function: mean 38.32; three studies; N = 246; MD -10.16, 95% CI -15.39 to -4.94; absolute change in improvement of 10% (15% to 5%) and relative change in improvement of 21.9% (33% to 11%); and fatigue: mean 68; three studies; N = 286; MD -6.48, 95% CI -14.33 to 1.38; absolute change in improvement of 6% (12% improvement to 0.3% worse) and relative change in improvement of 8% (16% improvement to 0.4% worse). Pooled analysis resulted in a risk ratio (RR) of moderate quality for withdrawals (17 per 100 and 20 per 100 in control and intervention groups, respectively; eight studies; N = 456; RR 1.25, 95%CI 0.89 to 1.77; absolute change of 5% more withdrawals with exercise (3% fewer to 12% more).Three trials provided low-quality evidence on long-term effects (24 to 208 weeks post intervention) and reported that benefits for pain and function persisted but did not for HRQL or fatigue. Withdrawals were similar, and investigators did not assess stiffness and adverse events.We are uncertain about the effects of one aerobic intervention versus another, as the evidence was of low to very low quality and was derived from single trials only, precluding meta-analyses. Similarly, we are uncertain of the effects of aerobic exercise over active controls (ie, education, three studies; stress management training, one study; medication, one study) owing to evidence of low to very low quality provided by single trials. Most studies did not measure adverse events; thus we are uncertain about the risk of adverse events associated with aerobic exercise. AUTHORS' CONCLUSIONS: When compared with control, moderate-quality evidence indicates that aerobic exercise probably improves HRQL and all-cause withdrawal, and low-quality evidence suggests that aerobic exercise may slightly decrease pain intensity, may slightly improve physical function, and may lead to little difference in fatigue and stiffness. Three of the reported outcomes reached clinical significance (HRQL, physical function, and pain). Long-term effects of aerobic exercise may include little or no difference in pain, physical function, and all-cause withdrawal, and we are uncertain about long-term effects on remaining outcomes. We downgraded the evidence owing to the small number of included trials and participants across trials, and because of issues related to unclear and high risks of bias (performance, selection, and detection biases). Aerobic exercise appears to be well tolerated (similar withdrawal rates across groups), although evidence on adverse events is scarce, so we are uncertain about its safety.

Dance for Adults With Fibromyalgia-What Do We Know About It? Protocol for a Scoping Review.

BACKGROUND: Fibromyalgia is a chronic disorder characterized by widespread muscular tenderness, pain, fatigue, and cognitive difficulties. Nonpharmacological treatment options, such as physical activity, are important for people with fibromyalgia. There are strong recommendations to support engagement in physical activity for symptom management among adults with fibromyalgia. Dance is a mode of physical activity that may allow individuals with fibromyalgia to improve their physical function, health, and well-being. Dance has the potential to promote improved pain processing while simultaneously providing the health and social benefits of engaging in physical activity that contributes to symptom management. However, we are unaware of current evidence on dance as a nonpharmacological/physical activity intervention for adults with fibromyalgia. OBJECTIVE: The aims of the study are to provide an overview of the extant evidence to understand how dance is used for individuals with fibromyalgia; to examine the extent, range, and nature of research activity in the area; and to determine the value of undertaking a full systematic review. METHODS: Scoping reviews are useful to comprehensively and systematically map the literature and identify key evidence, or research gaps. The search strategy will involve electronic databases including Medline, Embase, Cochrane Library, PsycInfo, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Literature in the Health Sciences in Latin America and the Caribbean (LILACS), Allied and Complementary Medicine (AMED), International Bibliography of Theatre and Dance, Physiotherapy Evidence Database (PEDro), Trip, Proquest Theses/Dissertations, Web of Science, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. The study will be mapped in seven stages: (1) identifying the research questions, (2) identifying relevant studies, (3) selecting the studies, (4) charting the data, (5) collating, summarizing and reporting the results, (6) consulting, and (7) disseminating the knowledge. RESULTS: The search, title, and abstract are now completed; full text screening was carried out and authors are awaiting interlibrary loans and translations. Data extraction will start shortly after full text 'screening' is completed. Completion is expected in Fall 2017. CONCLUSIONS: To our knowledge this will be the first attempt to systematically identify knowledge of dance as a potential intervention for adults with fibromyalgia. This scoping review offers a feasible means for describing the evidence specific to dance and fibromyalgia; results will provide unique insights concerning the breadth and depth of literature in the area. An analysis of this body of literature as a whole may reveal new research directions or unknown ways this intervention could strengthen current management approaches of the disease.

Torque and Muscle Activation Impairment Along With Insulin Resistance Are Associated With Falls in Women With Fibromyalgia.

Góes, SM, Stefanello, JMF, Homann, D, Lodovico, A, Hubley-Kozey, CL, and Rodacki, ALF. Torque and muscle activation impairment along with insulin resistance are associated with falls in women with fibromyalgia. J Strength Cond Res 30(11): 3155-3164, 2016-Fibromyalgia (FM) is a chronic pain condition associated with reduced muscle strength, which can lead to functional incapacity and higher risk of falls. The purpose of the study was to compare maximal ankle joint torque, muscle activation, and metabolic changes between women with and without FM. In addition, the relationship between those aspects and retrospectively reported falls in women with FM was determined. Twenty-nine middle-aged women with FM and 30 controls were recruited. Fall history, pain intensity, and pain threshold were assessed. Plasma glucose levels and insulin resistance (IR) were determined. Peak torque and rate of torque development (RTD) were calculated, and muscle activation was assessed from maximum isometric voluntary ankle dorsiflexion and plantar flexion contractions. In addition, voluntary muscle activation failure of the anterior tibialis muscle during maximal dorsiflexion was calculated. When compared to controls, women with FM reported higher number of retrospectively reported falls, exhibited higher IR, showed reduced plantar flexion and dorsiflexion RTD, had lower plantar flexion peak torque, and demonstrated more antagonist coactivation and higher muscle activation failure (p ≤ 0.05). Higher muscle activation failure was explained by glucose level and pain intensity (adj R = 0.28; p ≤ 0.05). Reduced plantar flexion and dorsiflexion peak torque explained 80% of retrospectively reported falls variance; also, high antagonist coactivation (odds ratio [OR] = 1.6; p ≤ 0.05) and high IR (OR = 1.8; p ≤ 0.05) increased the chance of falls in the FM group. A combination of metabolic factors and muscle function increased the odds of retrospectively reporting a fall in FM. Both aspects may be considered in interventions designed for reducing falls in this population.

Ankle dorsiflexion may play an important role in falls in women with fibromyalgia.

BACKGROUND: Fibromyalgia is a chronic pain condition, which involves reduced range of motion. This leads to gait changes and high incidence of falls. The understanding of the gait patterns in subjects with fibromyalgia and their relationship with falls may be useful when designing intervention programs. The purpose of this study was to evaluate the range of motion of the hip and ankle joints during gait in women with and without fibromyalgia. Further, we determined the relationship between joint range of motion and falls in this population. METHODS: Middle-aged women (16 with fibromyalgia and 16 as control group) were recruited. Pain intensity, physical activity level, and fall prevalence were assessed. Three dimensional gait analysis provided temporal and joint kinematic variables. FINDINGS: In general, hip and ankle range of motion were similar between groups, except that fibromyalgia group showed higher plantar flexion during toe-off (P<0.05) and reduced dorsiflexion during stance phase (P<0.05). Additionally, in the fibromyalgia group the higher number of falls was correlated to reduced dorsiflexion during stance phase. This limitation in dorsiflexion was related to longer length of time with fibromyalgia symptoms. INTERPRETATION: Women with fibromyalgia showed a higher number of falls, reduced dorsiflexion during stance phase, and increased plantar flexion during toe-off. Also, the higher number of falls reported in the fibromyalgia group was related to reduced dorsiflexion during stance phase, which was correlated to a longer length of time living with fibromyalgia symptoms. These data suggest that improving ankle kinematics in patients with fibromyalgia may help prevent falls and improve mobility.

Características da marcha de mulheres com fibromialgia: um padrão prematuro de envelhecimento / Gait characteristics of women with fibromyalgia: a premature aging pattern

Introdução: Fibromialgia é uma condição que envolve dor crônica generalizada. Além disso, mulheres de meia idade com fibromialgia apresentam alterações no padrão de marcha, expondo-se prematuramente a um padrão de marcha semelhante ao encontrado na população idosa. Objetivo: Determinar os parâmetros espaciais (linear e angular) da marcha de mulheres com fibromialgia e compará-los com idosas sem essa condição. Métodos: 25 mulheres (10 no grupo com fibromialgia e 15 no grupo de idosas) se qualificaram como voluntárias para participar do estudo. A análise cinemática foi realizada por meio de um sistema optoeletrônico, e as variáveis lineares e angulares foram determinadas. Resultados: Ambos os grupos apresentaram similaridades na velocidade da marcha, tamanho da passada, cadência e amplitude de movimento do quadril, joelho e tornozelo (p > 0,05), exceto para a rotação da pelve, na qual o grupo com fibromialgia apresentou maior rotação de quadril (p < 0,05) quando comparado ao grupo de idosas. Além disso, houve correlação negativa no grupo com fibromialgia entre rotação do quadril e dor no glúteo (r = -0,69; p < 0,05), e entre obliquidade da pelve e dor na região do trocanter maior (r = -0,69; p < 0,05). Conclusão: Mulheres de meia idade com fibromialgia apresentaram um padrão de marcha similar ao de idosas, o qual é caracterizado por amplitude de movimento, tamanho da passada e velocidade da marcha reduzidos. .

Background: Fibromyalgia is a condition which involves chronic pain. Middle-aged individuals with fibromyalgia seem to exhibit changes in gait pattern, which may prematurely expose them to a gait pattern which resembles that found in the elderly population. Objective: To determine the 3 D spatial (linear and angular) gait parameters of middle-aged women with fibromyalgia and compare to elderly women without this condition. Methods: 25 women (10 in the fibromyalgia group and 15 in the elderly group) volunteered to participate in the study. Kinematics was performed using an optoelectronic system, and linear and angular kinematic variables were determined. Results: There was no difference in walking speed, stride length, cadence, hip, knee and ankle joints range of motion between groups, except the pelvic rotation, in which the fibromyalgia group showed greater rotation (P < 0.05) compared to the elderly group. Also, there was a negative correlation with pelvic rotation and gluteus pain (r = - 0.69; P < 0.05), and between pelvic obliquity and greater trochanter pain (r = - 0.69; P < 0.05) in the fibromyalgia group. Conclusion: Middle-aged women with fibromyalgia showed gait pattern resemblances to elderly, women, which is characterized by reduced lower limb ROM, stride length and walking speed. .

Dor, qualidade de vida, autopercepção de saúde e depressão de pacientes com fibromialgia, tratados com hidrocinesioterapia / Pain, quality of life, self perception of health and depression in patients with fibromyalgia, submited to hydrocinesiotherapy

OBJETIVOS: Analisar os efeitos do tratamento hidrocinesioterapêutico na qualidade de vida, percepção de dor e gravidade de episódios depressivos em um grupo de pacientes com fibromialgia. MATERIAIS E MÉTODOS: Foram avaliados 64 indivíduos do sexo feminino, separados em dois grupos: hidrocinesioterapia (n = 33; 58,2 ± 10,6 anos) e grupo controle (n = 31; 59,6 ± 9,4 anos), com diagnóstico de fibromialgia. Os indivíduos foram avaliados através da Escala Analógica Visual de Dor (EVA), o Fibromyalgia Impact Questionnaire (FIQ), e o Inventário de Beck. Os participantes foram submetidos a um tratamento hidrocinesioterápico numa piscina aquecida a 33ºC com duas sessões de 45 minutos por semana, ao longo 15 semanas, num total de 30 sessões. Os exercícios subaquáticos foram: de condicionamento cardiovascular, de força, de mobilidade, de coordenação, de equilíbrio, de alongamento e de relaxamento muscular. Utilizou-se a ANOVA 2×2 e Kruskal-Wallis para análise estatística. RESULTADOS: Foram observadas melhorias estatisticamente significativas na percepção da intensidade da dor (Δ% = -28,2%, p < 0,01), na qualidade de vida (Δ% = -32,4%, p < 0,05) e nos sintomas de depressão (Δ% = -35,4%, p < 0,05) favoráveis ao grupo hidrocinesioterapia comparado ao grupo controle. CONCLUSÕES: O estudo sugere que a hidrocinesioterapia mostrou-se eficaz como terapia alternativa da fibromialgia. No entanto, recomenda novos estudos que testem as associações existentes entre as variáveis analisadas e os programas de intervenção, utilizando as atividades aquáticas, bem como a modificabilidade dos parâmetros de saúde física e psíquica quando estes indivíduos são submetidos a programas de curta, média e longa duração.

OBJECTIVES: The aim of this study was to analyze the effects of treatment by hydrotherapy on quality of life, perception of pain and the severity of depression in a group of patients with fibromyalgia. MATERIALS AND METHODS: We evaluated 64 females divided into two groups: hydrocinesiotherapy (n = 33, 58.2 ± 10.6 years) and control group (n = 31 with 59.6 ± 9.4 years) with clinical diagnosis of fibromyalgia. Individuals were assessed by Visual Analog Scale of Pain (VAS), the Fibromyalgia Impact Questionnaire (FIQ) and the Beck Depression Inventory. Participants underwent a treatment in a hydrotherapy pool heated to 33ºC over a period of 15 weeks, two sessions per week of 45 minutes, a total of 30 sessions. The exercises were underwater: cardiovascular conditioning, strength training, mobility, coordination, balance and still, stretching exercises and muscle relaxation. The ANOVA 2×2 and Kruskall-Wallis was used for statistical analysis RESULTS: There were statistically significant improvements in the perception of pain intensity (Δ% = -28.2%, p < 0, 01), quality of life (Δ% = -32.4%, p < 0, 05) and depression symptoms (Δ% = -35.4%, p < 0, 05) in favor of the Hydrotherapy group compared to the control group. CONCLUSIONS: The study suggests that hydrocinesiotherapy was effective as an alternative therapy for fibromyalgia, however further studies are recommended to test the associations between the variables and intervention programs and using the water activities, and the modifiability of the parameters of physical and mental health when these individuals undergo programs of short, medium and long duration.

Pain, quality of life, self perception of health and depression in patients with fibromyalgia, submited to hydrokinesiotherapy.

OBJECTIVES: The aim of this study was to analyze the effects of treatment by hydrotherapy on quality of life, perception of pain and the severity of depression in a group of patients with fibromyalgia. MATERIALS AND METHODS: We evaluated 64 females divided into two groups: hydrocinesiotherapy (n = 33, 58.2 ± 10.6 years) and control group (n = 31 with 59.6 ± 9.4 years) with clinical diagnosis of fibromyalgia. Individuals were assessed by Visual Analog Scale of Pain (VAS), the Fibromyalgia Impact Questionnaire (FIQ) and the Beck Depression Inventory. Participants underwent a treatment in a hydrotherapy pool heated to 33ºC over a period of 15 weeks, two sessions per week of 45 minutes, a total of 30 sessions. The exercises were underwater: cardiovascular conditioning, strength training, mobility, coordination, balance and still, stretching exercises and muscle relaxation. The ANOVA 2 × 2 and Kruskall-Wallis was used for statistical analysis RESULTS: There were statistically significant improvements in the perception of pain intensity (Δ% = -28.2%, p < 0, 01), quality of life (Δ% = -32.4%, p < 0, 05) and depression symptoms (Δ% = -35.4%, p < 0, 05) in favor of the Hydrotherapy group compared to the control group. CONCLUSIONS: The study suggests that hydrocinesiotherapy was effective as an alternative therapy for fibromyalgia, however further studies are recommended to test the associations between the variables and intervention programs and using the water activities, and the modifiability of the parameters of physical and mental health when these individuals undergo programs of short, medium and long duration.

Functional capacity, muscle strength and falls in women with fibromyalgia.

BACKGROUND: Patients with fibromyalgia have difficulty with activities of daily living, they exhibit reduced muscle strength and high incidence of reported falls. The objective of this study was to evaluate the functional performance and lower limb muscle strength in women with fibromyalgia and determine the relationship between muscle strength and falls. METHODS: Sixteen females with fibromyalgia and 16 healthy women participated in the study. Pain intensity, fibromyalgia impact on quality of life, physical activity level and fall prevalence were assessed. The peak torque and the rate of torque development were determined in maximal voluntary isometric contraction (hip, knee and ankle joints) using a load cell. The 30s chair stand, 8 ft up and go, sit and reach, and functional reach tests were used to characterize functional performance. FINDINGS: Women with fibromyalgia showed deficits in lower limb muscle strength, balance and agility and exhibited decreased knee extension peak torque and rate of torque development. In addition, they showed lower hip adduction and extension peak torque in comparison to the control group (P>0.05). Hip extension rate of torque development, duration of fibromyalgia symptoms, overall pain, knee pain, and fibromyalgia impact were strong predictors of the number of falls in patients with fibromyalgia (R2=0.86; P<0.05), when considered collectively. INTERPRETATION: Women with fibromyalgia showed reduced functional performance and lower limb muscle strength, mostly explained by pain. There was a high prevalence of falls in this population, as explained by hip extensors rate of torque development, duration of fibromyalgia symptoms and pain.

Redução da capacidade funcional e exacerbação da dor durante o esforço do teste de caminhada de 6 minutos em mulheres com fibromialgia / Impaired functional capacity and exacerbation of pain and exertion during the 6-minute walk test in women with fibromyalgia

CONTEXTUALIZAÇÃO: A fibromialgia (FM) parece limitar o desempenho físico, e a realização de atividades da vida diária (AVDs) pode exacerbar a dor e o esforço percebido nesses pacientes. OBJETIVOS: Comparar o desempenho do teste de caminhada de 6 minutos (TC6) entre pacientes com FM e controles e verificar relações entre esse desempenho com o impacto na qualidade de vida, na realização de tarefas da vida diária e no nível de atividade física. MÉTODOS: Participaram do estudo 19 mulheres com FM e 20 mulheres saudáveis. Realizou-se o TC6 e, durante o teste, foram mensuradas a intensidade de dor e a percepção subjetiva de esforço (PSE). Foram aplicados o Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ) e o International Physical Activity Questionnaire (IPAQ). RESULTADOS: O grupo de mulheres com FM percorreu menor distância no TC6 (pacientes: 473,52±77,84 m versus controles: 541,75±85,62 m; p=0,02). Para o grupo de pacientes houve correlações entre a distância caminhada e o questionário FIQ (r=-0,46; p=0,05), o HAQ (r=-0,49; p=0,03) e o consumo de oxigênio (r=0,78; p<0,01) e entre o HAQ e o consumo de oxigênio (r=-0,52; p=0,02). Durante o teste, as mulheres com FM apresentaram aumento da intensidade dolorosa e da PSE, o que não ocorreu no grupo controle. CONCLUSÕES: Mulheres com FM apresentaram comprometimento da capacidade funcional e exacerbação da dor e esforço durante o TC6.

BACKGROUND: Fibromyalgia has been association with physical performance limitations. Additionally, activities of daily living have been reported to be directly associated with the exacerbation of pain and perceived exertion in this patient population. OBJECTIVES: To compare the performance of a 6-minute walk (6MWT) test in patients with fibromyalgia and controls and to evaluate the relationship between test performance and quality of life, limitations of activities of daily living and physical activity level. METHODS: The study included 19 women with fibromyalgia (FM) and 20 healthy controls (CG). A 6MWT was conducted and pain intensity and perceived effort (PE) were assessed during the test. In addition, Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ) and International Physical Activity Questionnaire (IPAQ) were applied. RESULTS: The fibromyalgia group walked significantly shorter distances when compared to the control group (FM: 473.52±77.84 m vs. CG: 541.75±85.62 m; p=0.02). In the fibromyalgia group, there was a negative correlation between distance in 6MWT and FIQ (r=-0.46; p=0.05), HAQ (r=-0.49; p=0.03) and oxygen consumption (r=0.78; p<0.01). There was also a correlation between HAQ and oxygen consumption (r=0.52; p=0.02). Participants with fibromyalgia had higher pain intensity and perceived effort during the test when compared to the control group. CONCLUSIONS: Women with fibromyalgia had greater impaired of functional capacity, exacerbation of pain and exertion during the 6MWT when compared to healthy women.
