Aquatic exercise for people with asthma: a systematic review with meta-analysis of randomized controlled trials.

INTRODUCTION: Aquatic exercises are among the types of exercise most tolerated by people with asthma. Therefore, the objective of this study was to synthesize the evidence on the effects of aquatic exercise on lung function and quality of life in asthmatic patients. DATA SOURCES: A systematic search encompassing the Medline, CINAHL, Cochrane Library, Embase, AMED, SPORTDiscus, and Physiotherapy Evidence Database databases was conducted to identify randomized controlled trials assessing the impact of aquatic exercise in comparison to control conditions or land-based exercise on lung function and quality of life in individuals diagnosed with asthma. STUDY SELECTIONS: The stages of selection, data extraction and methodological evaluation, and level of evidence of the manuscripts were carried out independently by two authors. RESULTS: Ten studies, comprising a total of 393 participants, were incorporated into this systematic review. Very low-quality evidence was found in favor of aquatic exercise in asthmatic patients for forced expiratory volume in 1 s (MD: 0.20 L, 95% CI: 0.02 L-0.38L N: 91) and for forced vital capacity (MD: 0.32 L, 95% CI: 0.08 L-0.56L N: 80). No effect of aquatic exercise was observed on the FEV1/FVC ratio (MD:1.11L, 95% CI: -1.28 L-3.49L N:80) compared with control. Only one study evaluated the effect of aquatic exercise on patients' quality of life. CONCLUSIONS: Improvements in lung function and quality of life in asthmatic patients undergoing aquatic exercise are not supported by high-quality evidence. The present findings will need to be confirmed by new, methodologically more rigorous clinical trials.

The effect of aquatic exercise on pulmonary function and quality of life in asthma patients is still uncertain.The current quality of evidence for aquatic exercise in asthma patients is low.There is an urgent need for higher-quality studies investigating the effects of aquatic exercise among asthma patients.

Efficacy of pharmacological and non-pharmacological therapy on pain intensity and disability of older people with chronic nonspecific low back pain: a protocol for a network meta-analysis.

BACKGROUND: The purpose of this network meta-analysis (NMA) is to investigate the efficacy of pharmacological and non-pharmacological therapy on pain intensity and disability of older people with chronic nonspecific low back pain, providing comprehensive evidence for an informed decision-making. METHODS: We will perform a systematic search to identify randomized controlled trials of pharmacological and non-pharmacological interventions for older people with chronic nonspecific low back pain. MEDLINE, Cochrane Library, Embase, AMED, PsycINFO, and PEDro will be searched without language or date restrictions. Our primary outcomes are pain intensity and disability. Risk of bias will be assessed for all studies using the revised Cochrane risk-of-bias (RoB) tool 2.0. For each pairwise comparison between the different interventions, estimated mean differences and their 95% confidence intervals will be presented. Standard pairwise meta-analyses will be performed using random effects models in STATA version 16. The competing interventions will be ranked using the surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at short and long terms. The confidence in the results from NMA will be assessed using the Confidence in Network Meta-Analysis (CINeMA) framework. DISCUSSION: This NMA compares efficacy of interventions for nonspecific chronic low back pain in older people. It will provide reliable evidence for patients, clinicians, stakeholders, and researchers in this field where competing therapies, many of extraordinarily little value, are commonly used in clinical practice.

Efficacy of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis: a systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of pharmacological and non-pharmacological therapies on pain intensity and disability for plantar fasciitis. DESIGN: Systematic review of randomised controlled trials (RCTs). DATA SOURCES: AMED, MEDLINE, PEDro, Cochrane, SPORTDiscus, CINAHL, EMBASE and PsycINFO without language or date restrictions up to 3 February 2023. ELIGIBILITY CRITERIA: RCTs that evaluated the efficacy of any pharmacological and non-pharmacological therapies compared with control (placebo, sham, waiting list or no intervention) on pain intensity and disability in people with plantar fasciitis. Two reviewers independently screened eligible trials, extracted data, assessed the methodological quality of included trials and assessed the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations framework. Mean differences (MDs) with 95% CIs were reported. RESULTS: Seventeen different therapies investigated in 28 trials were included in the quantitative analysis. For non-pharmacological therapies, moderate certainty evidence showed short-term effects of customised orthoses on pain intensity when compared with control (MD of -12.0 points (95% CI -17.1 to -7.0) on a 0-100 scale). Low certainty evidence showed short-term effects of taping on pain intensity (-21.3 (95% CI -38.6 to -4.0)). Long-term effects and effects on disability are still uncertain. For pharmacological therapies, low to very low quality evidence from few trials with small samples was inconclusive and supports that high-quality trials are needed. CONCLUSIONS: Moderate-quality and low-quality evidence demonstrates customised orthoses and taping, respectively, reduce pain intensity in the short term in patients with plantar fasciitis.

Inflammatory biomarkers at different stages of Sarcopenia in older women.

In recent years, studies have found that Sarcopenia alters inflammatory biomarkers. However, the behavior of inflammatory biomarkers at different stages of Sarcopenia is not well understood. This study aimed to compare a broad panel of inflammatory biomarkers in older women at different stages of Sarcopenia. The study included 71 Brazilian community-dwelling older women. Muscle Strength was assessed by using handgrip strength (Jamar dynamometer). The Short Physical Performance Battery (SPPB) was performed to assess the physical performance, and body composition was assessed by DEXA. Sarcopenia was diagnosed and classified according to the EWGSOP2 criteria. Blood was drawn, and inflammatory biomarkers associated with Sarcopenia (IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, TNF, adiponectin, leptin, resistin, BDNF, sTNFr-1 and sTNFr-2) was analysed. After diagnosis and classification of sarcopenia, 45% of women did not present Sarcopenia (NS, N = 32), 23.9% were diagnosed with Sarcopenia Probable (SP, N = 17), 19,7% with Sarcopenia Confirmed (SC, N = 14), and 11.3% with Severe Sarcopenia (SS, N = 8). The analysis of inflammatory biomarkers revealed that the more advanced the stage of Sarcopenia, the higher the levels of BDNF, IL-8, sTNFr-1, and sTNFr-2. The assessment of BDNF, IL-8, sTNFr-1, and sTNFr-2 levels may be an adjuvant tool in diagnosis and severity classification of Sarcopenia in older Brazilian women.

The Efficacy of Manual Therapy Approaches on Pain, Maximum Mouth Opening and Disability in Temporomandibular Disorders: A Systematic Review of Randomised Controlled Trials.

Temporomandibular disorder (TMD) is a common condition disabling people and bringing up costs. The aim of this study was to investigate the effects of manual therapy on pain intensity, maximum mouth opening (MMO) and disability. Searches were conducted in six databases for randomised controlled trials (RCTs). Selection of trials, data extraction and methodological quality assessment were conducted by two reviewers with discrepancies resolved by a third reviewer. Estimates were presented as mean differences (MDs) or standardized mean differences (SMDs) with 95% confidence intervals (CIs). Quality of the evidence was assessed using the GRADE approach. Twenty trials met the eligibility criteria and were included. For pain intensity, high and moderate quality evidence demonstrated the additional effects of manual therapy at short- (95% CI -2.12 to -0.82 points) and long-term (95% CI -2.17 to -0.40 points) on the 0-10 points scale. For MMO, moderate to high quality evidence was found in favour of manual therapy alone (95% CI 0.01 to 7.30 mm) and its additional effects (95% CI 1.58 to 3.58 mm) at short- and long-term (95% CI 1.22 to 8.40 mm). Moderate quality evidence demonstrated an additional effect of manual therapy for disability (95% CI = -0.87 to -0.14). Evidence supports manual therapy as effective for TMD.

Effectiveness of Physical Therapy Interventions in Children with Brachial Plexus Birth Injury: A Systematic Review.

AIM: To systematically review the effectiveness of physical therapy interventions in infants, children and adolescents with brachial plexus birth injury (BPBI). METHODS: Systematic review of randomized controlled trials including patients under 18 years old with BPBI was conducted on Medline, Cochrane, Embase, Amed and Pedro databases. Methodological quality was assessed by the PEDro score and quality of evidence by the GRADE system. The primary outcomes measured were range of motion, muscle strength and bone mineral density. RESULTS: Seven studies were included, two in infant and 5 in children, of 932 title and abstracts screened. The interventions, characteristics of the participants and outcomes were diverse. The largest effect was found when other intervention was combined with conventional physical therapy in the primary outcomes, with low quality of evidence. CONCLUSION: Physical therapy interventions alone or in combination with other treatment modalities are effective in improving short-term disabilities in children with BPBI.

Adiponectin Is a Contributing Factor of Low Appendicular Lean Mass in Older Community-Dwelling Women: A Cross-Sectional Study.

Inflammation is a chronic, sterile, low-grade inflammation that develops with advanced age in the absence of overt infection and may contribute to the pathophysiology of sarcopenia, a progressive and generalized skeletal muscle disorder. Furthermore, a series of biomarkers linked to sarcopenia occurrence have emerged. To aid diagnostic and treatment strategies for low muscle mass in sarcopenia and other related conditions, the objective of this work was to investigate potential biomarkers associated with appendicular lean mass in community-dwelling older women. This is a cross-sectional study with 71 older women (75 ± 7 years). Dual-energy X-ray absorptiometry was used to assess body composition. Plasmatic blood levels of adipokines (i.e., adiponectin, leptin, and resistin), tumor necrosis factor (TNF) and soluble receptors (sTNFr1 and sTNFr2), interferon (INF), brain-derived neurotrophic factor (BDNF), and interleukins (IL-2, IL-4, IL-5, IL-6, IL-8, and IL-10) were determined by enzyme-linked immunosorbent assay. Older women with low muscle mass showed higher plasma levels of adiponectin, sTNFr1, and IL-8 compared to the regular muscle mass group. In addition, higher adiponectin plasma levels explained 14% of the lower appendicular lean mass. High adiponectin plasmatic blood levels can contribute to lower appendicular lean mass in older, community-dwelling women.

Recent Advance Analysis of Recovery in Hospitalized People with COVID-19: A Systematic Review.

INTRODUCTION: COVID-19 is a public health emergency all around the world. Severe illness occurred in about 14% of patients and 5% of patients developed critical illness, but the prognosis for these patients remains unclear. OBJECTIVE: To describe the prognosis in hospitalized adults with COVID-19. METHODS: The MEDLINE, EMBASE, AMED, and COCHRANE databases were searched for studies published up to 28 June 2021 without language restrictions. Descriptors were related to "COVID-19" and "prognosis". Prospective inception cohort studies that assessed morbidity, mortality and recovery in hospitalized people over 18 years old with COVID-19 were included. Two independent reviewers selected eligible studies and extracted the available data. Acute respiratory distress syndrome (ARDS) and multiple organ failure (MOFS) were considered as outcomes for morbidity and discharge was considered for recovery. The Quality in Prognosis Studies (QUIPS) tool was used to assess risk of bias. Analyses were performed using Comprehensive Meta-Analysis (version 2.2.064). RESULTS: We included 30 inception cohort studies investigating 13,717 people hospitalized with COVID-19 from different countries. The mean (SD) age was 60.90 (21.87) years, and there was high proportion of males (76.19%) and people with comorbidities (e.g., 49.44% with hypertension and 29.75% with diabetes). Findings suggested a high occurrence of morbidity, mainly related to ARDS. Morbidity rates varied across studies from 19% to 36% in hospital wards, and from 13% to 90% in Intensive Care Units-ICU. Mortality rates ranged from 4% to 38% in hospital wards and from 8% to 51% in ICU. Recovery rates ranged up to 94% and 65% in hospital wards and ICU, respectively. The included studies had high risk of bias in the confounding domain. CONCLUSIONS: The prognosis of people hospitalized with COVID-19 is an issue for the public health system worldwide, with high morbidity and mortality rates, mainly in ICU and for patients with comorbidities. Its prognosis emphasizes the need for appropriate prevention and management strategies.

The ESCAPE trial for older people with chronic low back pain: Protocol of a randomized controlled trial.

BACKGROUND: Low-back pain is one of the most common health conditions worldwide. It is defined as pain below the costal margin and above the inferior gluteal folds. Current guidelines recommend management of chronic health (e.g., low back pain) conditions in older people at primary health care settings using active strategies (e.g., exercise). In non-specific low back pain, high quality evidence supports active strategies for general population. However, the management of non-specific low back pain in the older people has been overlooked and evidence is limited to a small number of low powered randomized controlled trials with high risk of bias. METHODS: This is a prospectively registered, open, two-arm randomised controlled trial comparing the group-based exercise and waiting list in pain intensity (11-item Pain Numerical Rating Scale) and disability (Roland Morris questionnaire) of older people (i.e., 60 years old or over) with chronic non-specific low back pain. One hundred and twenty patients will be recruited from Diamantina, Brazil. Follow-ups will be conducted in post-treatment (8 week) and 6- and 12-months post-randomisation. DISCUSSION: Our hypothesis is that group-based exercise will be better than waiting list in reducing pain intensity and disability in older people with chronic non-specific low back pain. IMPACT: The practice of individualized exercise has been studied for the management of chronic non-specific low back pain in older people. However, the group exercise, even showing high quality evidence for the improvement of several important outcomes in this population, has been ignored until now. Thus, the results of this study have the potential to indicate a viable and accessible strategy for managing chronic non-specific low back pain in the older people. TRIAL REGISTRATION: The study was prospectively registered at www.ensaiosclinicos.gov.br (RBR-9j5pqs). Date-11/18/2020.

Immediate Effects of Whole-Body Vibration Associated with Squatting Exercises on Hemodynamic Parameters in Sarcopenic Older People: A Randomized Controlled Trial.

Whole-body vibration (WBV) exercises have recently been introduced as a nonpharmacological therapeutic strategy for sarcopenic older people. The present study aimed to evaluate the effect of WBV exercise on hemodynamic parameters in sarcopenic older people. Forty older people, divided into groups of nonsarcopenic (NSG = 20) and sarcopenic (SG = 20), participated in the study and were cross randomized into two interventions of eight sets of 40 s each, these being squatting with WBV and squatting without WBV. Heart rate (HR), peak heart rate (peak HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), mean arterial pressure (MAP), and subjective perception of effort (SPE), were assessed at baseline, during, and after a single WBV session. The HR, peak HR, and DP variables were similar at baseline between groups. WBV exercise increased all the hemodynamic parameters both during and immediately after the intervention, in both groups (SG and NSG). The MAP values were similar at baseline between groups; however, in the NSG there was a significant increase during and immediately after the squatting with WBV intervention (p < 0.05). The HR behavior, in both groups, showed that there was an increase in HR after the first set of exercises with vibration and this increase was maintained until the final set. The absence of adverse effects of WBV exercise on the cardiovascular system and fatigue suggests this exercise modality is adequate and safe for sarcopenic older people.

Effects of Photobiomodulation Therapy Combined With Exercise in Patients Who Have Chronic Low Back Pain: Protocol for a Randomized Controlled Trial.

OBJECTIVE: Although commonly prescribed, exercise therapy alone is insufficient for the treatment of low back pain (LBP). Thus, studies recommend a combination of interventions. Photobiomodulation therapy (PBMT) involving low-level laser is an effective intervention for relieving LBP; however, scientific evidence on the effects of laser therapy combined with exercise therapy is scarce and contradictory. The aim of this clinical trial is to evaluate the short-term and long-term effects of the combination of PBMT and an exercise protocol in individuals with persistent nonspecificLBP. METHODS: This 2-armed, randomized, placebo-controlled trial with blinded participants, assessors, and therapists will be conducted in the outpatient physical therapy clinic of a university in Diamantina, Brazil. Participants are 90 individuals between 18 and 65 years of age with self-reported LBP. The participants will be randomly allocated to (1) a 6-week exercise program combined with active PBMT at a frequency of twice per week, totaling 12 sessions (n = 45), or (2) a 6-week exercise program combined with placebo PBMT (n = 45). Clinical outcomes will be measured at baseline as well as at 8 and 20 weeks and 12 months after randomization. The primary outcomes will be pain intensity and disability. The secondary outcomes will be mental health, mobility, disability, and strength of the trunk extensor muscles. IMPACT: The findings will help determine whether adding PBMT to a physical therapist-supervised exercise protocol is more effective than the exercise protocol alone for persistent LBP. This study has the potential to guide clinical practice toward innovative ways of providing health care.

Effectiveness of cryotherapy on pain intensity, swelling, range of motion, function and recurrence in acute ankle sprain: A systematic review of randomized controlled trials.

OBJECTIVE: Investigate effectiveness of cryotherapy on pain intensity, swelling, range of motion, function and recurrence in acute ankle sprain. METHODS: Searches were conducted on six databases for randomized or quasi-randomized controlled trials (RCTs) evaluating effectiveness of cryotherapy for pain intensity, swelling, range of motion, function and recurrence in acute ankle sprain. Selection of trials, data extraction and methodological quality assessment of included trials were conducted independently by two reviewers with discrepancies resolved by a third reviewer. Estimates were presented as mean differences (MDs) with 95% confidence intervals (CIs). The quality of the evidence was assessed using the Grading of Recommendations Assessment (GRADE) approach. RESULTS: Two RCTs with high risk of bias were included. Both evaluated the additional effects of cryotherapy, comparing cryotherapy combined with other intervention versus other intervention stand-alone. Uncertain evidence shows that cryotherapy does not enhance effects of other intervention on swelling (MD = 6.0; 95%CI: 0.5 to 12.5), pain intensity (MD = -0.03; 95%CI: 0.34 to 0.28) and range of motion (p > 0.05). CONCLUSIONS: Current literature lacks evidence supporting the use of cryotherapy on management of acute ankle sprain. There is an urgent call for larger high-quality randomized controlled trials.

Effectiveness of conservative therapy in tendinopathy-related shoulder pain: A systematic review of randomized controlled trials.

OBJECTIVE: Systematic review investigated efficacy of conservative therapy on pain and function in people with tendinopathy-related shoulder pain. METHODS: Searches were conducted on six databases. All randomized controlled trials investigating efficacy of any conservative therapy on pain and function in people with tendinopathy-related shoulder pain were included. Estimates for each specific conservative therapy were presented as weighted mean differences (WMDs) or mean differences (MDs), with 95% confidence intervals (CIs). Quality of the evidence was assessed using GRADE. RESULTS: Five randomized controlled trials were included. Extracorporeal shock-wave therapy (ESWT) was effective on pain at short-term (i.e., ≤3 months) when compared with control (WMD = -1.7 out of 101 points, -3.1 to -0.3; n = 158). Individual trials also suggested effects of non-steroidal anti-inflammatory drugs (NSAIDs) (-13.7 to -2.3; n = 365) and extracorporeal radial pressure pulse therapy (rESWT) (-40.0 to -27.0; n = 79). Laser therapy and ESWT were not effective on pain and function at short-term, respectively. No trials investigated medium- or long-term effects, and quality of the evidence ranged from low to very low quality. CONCLUSIONS: Conservative therapies currently available for the rotator cuff management and biceps tendinopathy are not supported by low to very-low quality evidence.

Custos diretos da dor lombar em hospitais financiados pelo Sistema Único de Saúde / Direct costs of low back pain in hospitals financed by the Unified Health System

INTRODUÇÃO: A dor lombar é um sintoma altamente incapacitante, que leva a um impacto social negativo para as pessoas que experimentam o sintoma, e econômico para os cofres públicos de diversos países, com gastos excessivos e por vezes desnecessários com procedimentos não resolutivos. OBJETIVOS: Relatar o número de procedimentos clínicos e cirúrgicos e os custos diretos da dor lombar em hospitais financiados pelo Sistema Único de Saúde. MÉTODOS: Os dados sobre os procedimentos clínicos e cirúrgicos foram coletados no Sistema de Informações Hospitalares no website do DATASUS, no período entre 2013 e 2018. Realizou-se análise descritiva dos dados. RESULTADOS: nos seis anos analisados os procedimentos para tratamento da dor lombar custaram financeiramente R$ 24.427.238. Estes custos aumentaram de forma expressiva ao longo dos anos observados. Realizou-se 1.689 procedimentos cirúrgicos e cada um custou em média R$ 3.290. A região sudeste do país foi a que teve maior gasto financeiro para o tratamento do sintoma (R$ 12.442.930). CONCLUSÃO: O custo da dor lombar ao longo dos anos para o sistema público está aumentando rapidamente e provavelmente é impulsionado pelo aumento no número de cirurgias.

INTRODUCTION: Low back pain is a highly disabling symptom, which leads to a negative social impact for people who experience the symptom, and economic, for public coffers in several countries, with excessive and sometimes unnecessary expenses with non-resolving procedures. OBJECTIVES: To report the number of clinical and surgical procedures and the direct costs of low back pain in hospitals financed by the Unified Health System. METHODS: The data on clinical and surgical procedures were collected in the Hospital Information System on the DATASUS website between 2013 and 2018. A descriptive analysis of the data was carried. RESULTS: In the six years analyzed, the procedures for the treatment of low back pain cost R$ 24,427,238. These costs have increased significantly over the years observed. 1,689 surgical procedures were performed, and each cost an average of R$ 3,290. The southeastern region of the country was the one that had the greatest financial expenditure for the treatment of the symptom (R$ 12,442,930). CONCLUSION: The cost of low back pain over the years to the public system is increasing rapidly and is probably driven by the increase in the number of surgeries.

Factors associated with human visceral leishmaniasis cases during urban epidemics in Brazil: a systematic review.

Visceral leishmaniasis (VL) is endemic in 70 countries and has been reported in 12 countries of Latin America, with over 90% of the cases reported in Brazil, where epidemics have occurred since 1980. The objective of this review is to describe the factors associated with the occurrence of VL epidemics in humans in urban areas. A systematic review was conducted according to the PRISMA-P guidelines. The databases PubMed (by Medline), Cochrane Library, Embase, Amed, LILACS and grey literature [Google Scholar and handsearch of the database of the Information System for Notifiable Diseases (SINAN) of Brazil's Unified Health System] were used. The protocol was registered under PROSPERO (CRD42019128998). Climatic, environmental factors and indicators of urban social structure were described as influencing the outbreaks in the North and Northeast regions. Gender and age characteristics were related to a greater chance of developing VL in the Central-West, Northeast and Southeast regions. Vector indicators showed a positive correlation with the incidence of VL in studies in the Northeast region. In the Southeast and Northeast regions, studies revealed the presence of dogs with positive correlation with VL. Knowledge gaps remain regarding the contribution to the increase in the risk factors described in ecological approaches, as no analysis was performed at the individual level, and it is still necessary to discuss the influence of other associated elements in epidemic episodes in the spread of VL.

Effectiveness of exercises by telerehabilitation on pain, physical function and quality of life in people with physical disabilities: a systematic review of randomised controlled trials with GRADE recommendations.

OBJECTIVE: Investigate whether exercise-based telerehabilitation improves pain, physical function and quality of life in adults with physical disabilities. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES: Searches were performed in AMED, MEDLINE, CINAHL, SPORTDiscus, Embase, PEDro, Cochrane Library and PsycINFO. ELIGIBILITY CRITERIA: Trials were considered if they evaluated exercise by telerehabilitation. The population included adults with physical disability. Comparisons were control and other interventions. The outcomes were pain, physical function and quality of life. Study selection, data extraction and analysis followed the protocol registered in PROSPERO (CRD42019122824). GRADE determined the strength of evidence. RESULTS: Forty-eight trials were included in the quantitative analysis. When compared with other interventions, there was high-quality evidence that telerehabilitation was not different to other interventions for pain (95% CI: -0.4 to 0.1), physical function (95% CI: -0.2 to 0.2) and quality of life (95% CI: -0.1 to 0.5) at long-term. There was moderate-quality evidence that telerehabilitation was not different to other interventions for physical function (95% CI: -0.1 to 0.5) and quality of life (95% CI: -0.2 to 0.5) at short-term. However, due to the low-quality evidence and the small number of trials comparing exercise protocols offered by telerehabilitation with control groups, it is still not possible to state the efficacy of telerehabilitation on pain, function and quality of life at short-term and long-term. CONCLUSIONS: Exercise by telerehabilitation may be an alternative to treat pain, physical function and quality of life in adults with physical disabilities when compared with other intervention.

Association of Therapies With Reduced Pain and Improved Quality of Life in Patients With Fibromyalgia: A Systematic Review and Meta-analysis.

Importance: Fibromyalgia is a chronic condition that results in a significant burden to individuals and society. Objective: To investigate the effectiveness of therapies for reducing pain and improving quality of life (QOL) in people with fibromyalgia. Data Sources: Searches were performed in the MEDLINE, Cochrane, Embase, AMED, PsycInfo, and PEDro databases without language or date restrictions on December 11, 2018, and updated on July 15, 2020. Study Selection: All published randomized or quasi-randomized clinical trials that investigated therapies for individuals with fibromyalgia were screened for inclusion. Data Extraction and Synthesis: Two reviewers independently extracted data and assessed risk of bias using the 0 to 10 PEDro scale. Effect sizes for specific therapies were pooled using random-effects models. The quality of evidence was assessed using the Grading of Recommendations Assessment (GRADE) approach. Main Outcomes and Measures: Pain intensity measured by the visual analog scale, numerical rating scales, and other valid instruments and QOL measured by the Fibromyalgia Impact Questionnaire. Results: A total of 224 trials including 29 962 participants were included. High-quality evidence was found in favor of cognitive behavioral therapy (weighted mean difference [WMD], -0.9; 95% CI, -1.4 to -0.3) for pain in the short term and was found in favor of central nervous system depressants (WMD, -1.2 [95% CI, -1.6 to -0.8]) and antidepressants (WMD, -0.5 [95% CI, -0.7 to -0.4]) for pain in the medium term. There was also high-quality evidence in favor of antidepressants (WMD, -6.8 [95% CI, -8.5 to -5.2]) for QOL in the short term and in favor of central nervous system depressants (WMD, -8.7 [95% CI, -11.3 to -6.0]) and antidepressants (WMD, -3.5 [95% CI, -4.5 to -2.5]) in the medium term. However, these associations were small and did not exceed the minimum clinically important change (2 points on an 11-point scale for pain and 14 points on a 101-point scale for QOL). Evidence for long-term outcomes of interventions was lacking. Conclusions and Relevance: This systematic review and meta-analysis suggests that most of the currently available therapies for the management of fibromyalgia are not supported by high-quality evidence. Some therapies may reduce pain and improve QOL in the short to medium term, although the effect size of the associations might not be clinically important to patients.

Whole body vibration in the static modified push-up position in untrained healthy women stimulates neuromuscular system potentiating increased handgrip myogenic response.

OBJECTIVE: To investigate the acute effect of whole-body vibration (WBV) on handgrip strength (HS) and electromyographic activity of the flexor digitorum superficialis muscle of healthy women in the static push-up position. METHODS: Twenty-eight women received four experimental tests in a randomized order: A) Control - rest in seating position with feet on the floor and hands in the supine position on the lower limbs. There was no vibration stimulus; B) Placebo - push-up position with their hands on the vibratory platform that remained disconnected, but with a sonorous stimulus mimicking the vibration; C) Low vibration and D) High vibration - push-up position with their hands on the vibratory platform using one of the vibratory stimulus intensity: low vibration: 25 Hz/2 mm/49.30 m s-2; or high vibration: 45 Hz/2 mm/159.73 m s-2. Participants remained 5 min in each situation. HS and electromyography (EMG) were performed at baseline and after all four experimental tests. The index of neural efficiency (i.e. the ratio between EMG and HS) was also calculated to determine the efficiency of muscle contraction. Statistical analysis was performed by ANOVA two-way design mixed test with Tukey's post hoc test, being considered significant p < 0.05. RESULTS: High vibration increased HS compared with all the other experimental tests (p = 0.0006, F = 6.03). There was a reduction of EMG activity of the flexor digitorum superficialis muscle only after high vibration (p = 0.0135, F = 6.22), which was accompanied by lower values of the index of neural efficiency after intervention (between-group difference, p = 0.0002, F = 0.674). CONCLUSION: WBV in the push-up position has an acute positive effect on HS accompanied by a lower index of neural efficiency, providing a better efficiency of muscle contraction.

Epidural Corticosteroid Injections for Sciatica: An Abridged Cochrane Systematic Review and Meta-Analysis.

STUDY DESIGN: Systematic with meta-analysis OBJECTIVES.: The aim of this study was to investigate the efficacy and safety of epidural corticosteroid injections compared with placebo injection in reducing leg pain and disability in patients with sciatica. SUMMARY OF BACKGROUND DATA: Conservative treatments, including pharmacological and nonpharmacological treatments, are typically the first treatment options for sciatica but the evidence to support their use is limited. The overall quality of evidence found by previous systematic reviews varies between moderate and high, which suggests that future trials may change the conclusions. New placebo-controlled randomized trials have been published recently which highlights the importance of an updated systematic review. METHODS: The searches were performed without language restrictions in the following databases from 2012 to 25 September 2019: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, PubMed, Embase, CINAHL, PsycINFO, International Pharmaceutical Abstracts, and trial registers. We included placebo-controlled randomized trials investigating epidural corticosteroid injections in patients with sciatica. The primary outcomes were leg pain intensity and disability. The secondary outcomes were adverse events, overall pain, and back pain intensity. We grouped similar trials according to outcome measures and their respective follow-up time points. Short-term follow-up (>2 weeks but ≤3 months) was considered the primary follow-up time point due to the expected mechanism of action of epidural corticosteroid injection. Weighted mean differences (MDs) and risk ratios (RRs) with their respective 95% confidence intervals (CIs) were estimated. We assessed the overall quality of evidence using the GRADE approach and conducted the analyses using random effects. RESULTS: We included 25 clinical trials (from 29 publications) providing data for a total of 2470 participants with sciatica, an increase of six trials when compared to the previous review. Epidural corticosteroid injections were probably more effective than placebo in reducing short-term leg pain (MD -4.93, 95% CI -8.77 to -1.09 on a 0-100 scale), short-term disability (MD -4.18, 95% CI: -6.04 to -2.17 on a 0-100 scale) and may be slightly more effective in reducing short-term overall pain (MD -9.35, 95% CI -14.05 to -4.65 on a 0-100 scale). There were mostly minor adverse events (i.e., without hospitalization) after epidural corticosteroid injections and placebo injections without difference between groups (RR 1.14, 95% CI: 0.91-1.42). The quality of evidence was at best moderate mostly due to problems with trial design and inconsistency. CONCLUSION: A review of 25 placebo-controlled trials provides moderate-quality evidence that epidural corticosteroid injections are effective, although the effects are small and short-term. There is uncertainty on safety due to very low-quality evidence. LEVEL OF EVIDENCE: 1.
