RESUMEN
AIM: To refine the Gross Motor Family Report (GM-FR) using parents' input and to evaluate its psychometric properties. METHOD: In this measurement study, 12 parents of children and adolescents with cerebral palsy (CP), aged 2 to 18 years, classified in all levels of the Gross Motor Function Classification System (GMFCS), were interviewed about their experience completing the GM-FR (content validity). Parents' feedback was used to refine the measure which was then completed by 146 families to evaluate internal consistency, and discriminative and concurrent validity. Forty-six parents completed the GM-FR again, 7 to 30 days later, to evaluate test-retest reliability. RESULTS: GM-FR scoring, pictures, descriptions, and the total number of items were revised based on parents' feedback. The GM-FR version 2.0 demonstrated high internal consistency (Cronbach's α = 0.99), no floor/ceiling effects, and excellent test-retest reliability (intraclass correlation coefficient = 0.99). GM-FR scores discriminated between GMFCS levels (p < 0.05) and were strongly negatively correlated with GMFCS level (r = -0.92; p < 0.001). GM-FR scores correlated positively and strongly with the Gross Motor Function Measure-66 (r = 0.94; p < 0.001) and the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test mobility domain (r = 0.93; p < 0.001). INTERPRETATION: Active participation of families in the GM-FR's development facilitated creation of a family-friendly instrument. This study provides strong evidence of reliability and validity to support GM-FR use in clinical practice and research for assessing gross motor performance of children and adolescents with CP.
RESUMEN
AIMS: The purpose of this study was to assess the current clinical practice of physiotherapists and occupational therapists on early detection and early intervention for children with cerebral palsy (CP) in Brazil. METHODS: This was a cross-sectional study. A purpose-developed electronic survey was disseminated across the country to physiotherapists and occupational therapists working with young children with or at risk of CP. RESULTS: A total of 205 anonymous respondents were included. Most participants (64.4%) agree that the diagnosis of CP can be made before 6 months of age. General Movements Assessment (26.8%) and Hammersmith Infant Neurological Examination (37.1%) were used infrequently. Infants at risk for CP receive therapy twice a week or more by 58.5% of therapists, 93.2% identified parents' goals as the most important factor in customizing the early intervention program. The most frequent intervention strategies for this age group were active stimulation of the child (n = 182), family training (n = 161), strategies to optimize the environment (n = 143), and neurodevelopmental treatment/Bobath (n = 99). CONCLUSIONS: Currently, pediatric physiotherapists and occupational therapists in Brazil do not fully incorporate best practice tools for early identification of children with CP, nor sufficient best evidence-based interventions.
RESUMEN
BACKGROUND: Autism Spectrum Disorder (ASD) children have lower levels of participation in recreational and sporting activities when compared to their peers. Participation has been defined based on the Family of Participation-Related Constructs (fPRC) which defines participation as including both attendance and involvement, with sense of self, preferences and activity competence related to a child's participation. Modified sports interventions such as Sports Stars can act on physical literacy and some of the fPRCs components. This study aims to assess the feasibility of the Sports Stars Brazil intervention for children with ASD. METHODS: This study will be conducted with 36 participants with ASD aged 6 to 12 years old following the CONSORT for pilot and feasibility recommendation. Participants will be randomly allocated into two groups. Intervention group will receive eight, weekly Sports Stars sessions. Each session will include of sports-focused gross motor activity training, confidence building, sports-education and teamwork development. Study assessments will occur at baseline, immediately post-intervention and 20-weeks post-randomization. First, we will assess process feasibility measures: recruitment, assessment completion, adherence, adverse events and satisfaction. Second, we will investigate the scientific feasibility of the intervention by estimating the effect size and variance at the level of achievement sports-related activity and physical activity participation goals (Goal Attainment Scaling), activity competence (Ignite Challenge, Test of Gross Motor Development-second edition, Physical Literacy Profile Questionnaire, Pediatric Disability Assessment Inventory-Computer Adaptive Test-PEDI-CAT-mobility, 10×5 Sprint Test and Muscle Power Sprint Test), sense of self (PEDI-CAT-responsibility), and overall participation at home, school and community, (Participation and Environment Measure for children and young people, PEM-CY). DISCUSSION: The results of this feasibility study will inform which components are critical to planning and preparing a future RCT study, aiming to ensure that the RCT will be feasible, rigorous and justifiable. TRIAL REGISTRATION: The trial was registered with the Brazilian Registry of Clinical Trials database (ID: RBR-9d5kyq4) on June 15, 2022.

Purpose: To describe the initial steps in the development of a family-completed, modified version of the Gross Motor Function Measure (GMFM-88) to report gross motor function of young people with cerebral palsy in their natural environments. Methods: Development of the Gross Motor Function - Family Report (GMF-FR) was based on expert opinion involving 13 experienced clinicians and researchers, in four steps: (1) item identification to target items that reflect functional gross motor performance; (2) item selection; (3) critical analysis of the items; and (4) item and scoring modification. Results: Several modifications to existing items and scoring were made, including wording changes to optimize ease of families' understanding, the addition of photographs to illustrate all items, changes to the items to enable use of furniture instead of specialized equipment, and modifications to scoring criteria to ensure a focus on functional motor skills. Ultimately, 30 items were selected, and specific testing/scoring instructions were created for each item. Conclusions: GMF-FR is a new family-report tool, based on the GMFM-88. When validated, it can be used as a telehealth outcome measure to capture family-reported functional motor skill performance in home and community environments.
Objectif : décrire les premières étapes de l'élaboration d'une version modifiée de la mesure de la fonction motrice globale (GMFM-88) remplie par la famille pour rendre compte de la fonction motrice globale des jeunes ayant la paralysie cérébrale dans leur environnement naturel. Méthodologie : l'élaboration de l'outil de fonction motrice globale rapport familial (GMF-FR), qui repose sur l'avis d'experts soit 13 cliniciens et chercheurs d'expérience , s'est déclinée en quatre étapes : 1) détermination des points, pour cibler ceux qui reflète le rendement de la fonction motrice globale; 2) sélection des points; 3) analyse critique des points et 4) modifications aux points et aux scores. Résultats : les experts ont apporté plusieurs modifications aux points et aux scores en place, y compris de la reformulation pour que les familles comprennent plus facilement, l'ajout de photos pour illustrer tous les points, des changements aux points pour utiliser des meubles plutôt que du matériel spécialisé et la modification des critères des scores afin de se concentrer sur les habiletés motrices fonctionnelles. Au bout du compte, les experts ont retenu 30 points, chacun étant assorti de directives précises sur le test et le score. Conclusions : La mesure GMF-FR est un nouvel outil de déclaration par la famille, inspiré du GMFM-88. Une fois validé, il peut être utilisé comme mesure de résultats en télésanté, afin de saisir le rendement des habiletés motrices fonctionnelles à la maison et dans les environnements communautaires.
RESUMEN
A CIF pode ser usada para mapear uma série de desfechos por meio de estudos de desenvolvimento. Os principais desfechos investigados em crianças com PC foram atividade e estrutura e função corporal. Pouco tem sido explorado os desfechos de participação e fatores contextuais ao longo do tempo. A principal classificação utilizada para estratificar os participantes foi o Sistema de Classificação da Função Motora Grossa. Estudos futuros devem ampliar seu foco para diferentes áreas da CIF, e na transição para a vida adulta. Estudos sobre o desenvolvimento de indivíduos com PC ajudam terapeutas e pais a planejarem abordagens de tratamento e prognóstico futuro. Os principais desfechos investigados em indivíduos com PC foram atividade e estruturas e funções corporais. Pouco tem sido explorado em desfechos de participação e de fatores contextuais ao longo do tempo.
OBJETIVOS: Identificar e fornecer uma visão geral descritiva dos estudos de desenvolvimento de crianças, adolescentes e jovens adultos com paralisia cerebral (PC); e mapear áreas de foco de acordo com os componentes da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) da OMS. MÉTODO: Estudos longitudinais do desenvolvimento de crianças, adolescentes e/ou jovens adultos com PC foram incluídos nesta revisão de escopo. A busca por estudos elegíveis foi realizada nas bases de dados: MEDLINE, PubMed, LILACS, EMBASE, Cochrane, CINAHL, Scopus, e foi restrita aos anos de 2002-2022. Todas os desfechos dos estudos foram classificados em componentes da CIF. RESULTADOS: Nos 56 estudos incluídos, houve 19.438 participantes, envolvendo principalmente crianças, seguidas de adolescentes e, por último, jovens adultos. Todos os componentes da CIF foram investigados e muitos estudos relataram resultados em mais de um componente. O componente atividade foi o mais investigado (67,9%; n = 38 estudos), seguida da estrutura e função corporal (42,9%; n = 24 estudos). A participação (14,2%; n = 8 estudos) e os fatores ambientais (3,6%; n = 2 estudos) foram os menos estudados. Nenhum dos estudos investigou fatores pessoais como desfecho. INTERPRETAÇÃO: Esta revisão de escopo fornece uma visão geral dos estudos sobre o desenvolvimento de crianças, adolescentes e jovens adultos com PC, usando a estrutura da CIF, identificando áreas atuais de foco e lacunas. Estudos futuros devem visar a participação, os fatores contextuais e a transição para a vida adulta.

RESUMEN
AIM: To identify and provide a descriptive overview of the development of children, adolescents, and young adults with cerebral palsy (CP) in longitudinal studies; and map areas of focus according to the components of the World Health Organization's International Classification of Functioning, Disability, and Health (ICF). METHOD: Longitudinal studies of the development of children, adolescents, and/or young adults with CP were included in this scoping review. A search for eligible studies was conducted in the databases MEDLINE, PubMed, LILACS, EMBASE, Cochrane, CINAHL, and Scopus, and was restricted to the years 2002 to 2022. All outcome measures of the studies were classified into ICF components. RESULTS: In the 56 studies included, there were 19 438 participants, involving mainly children, followed by adolescents, and lastly young adults. All components of the ICF were investigated and many studies reported outcomes in more than one component. Activity was the most investigated (67.9%; n = 38 studies), followed by body functions and structures (42.9%; n = 24 studies). Participation (14.2%; n = 8 studies) and environmental factors (3.6%; n = 2 studies) were the least studied. None of the studies investigated personal factors as an outcome. INTERPRETATION: This scoping review provides an overview of studies on the development of children, adolescents, and young adults with CP, using the ICF framework, identifying current areas of focus and gaps in the research. Future studies should target participation, contextual factors, and the transition into adulthood. WHAT THIS PAPER ADDS: The International Classification of Functioning, Disability, and Health can be used to map a range of outcomes through developmental studies. The main outcomes investigated in children with cerebral palsy were activity, and body functions and structures. Little has been explored in participation and contextual factors outcomes over time. The main classification used to stratify the participants was the Gross Motor Function Classification System.

OBJETIVO: Identificar os instrumentos de avaliação para pessoas com distrofia muscular e investigar a qualidade/nível de evidência de suas propriedades de medidas. MÉTODOS: Uma revisão sistemática de medidas de resultado relatadas pelos pacientes foi conduzida nas bases de dados MEDLINE, Embase, AMED, DiTA e PsycINFO em agosto de 2020. Foram incluídos estudos psicométricos que investigaram a validade, confiabilidade e responsividade de instrumentos de medida que avaliam atividade e participação para distrofia muscular de qualquer tipo (Duchenne, becker, cinturas, facioescapuloumeral, congênita e miotônica) e idade. Dois revisores independentes selecionaram os estudos, extraíram dados e avaliaram a qualidade e nível de evidência dos instrumentos de medida seguindo o checklist COnsensus-based Standards for the Selection of health status Measurement INstruments (COSMIN). RESULTADOS: A busca identificou 6675 referências; um total de 46 estudos com 28 instrumentos de medida de condição-específica ou genéricos foram incluídos. As propriedades de medidas da maioria dos instrumentos tiveram resultados suficientes (68.8%) ou indeterminados (25.7%) de acordo com o COSMIN. A qualidade da evidência das propriedades de medidas foi moderada (23.8%) ou baixa (22.6%) de acordo com o Grading of Recommendations Assessment, Development, and Evaluation (GRADE). INTERPRETAÇÃO: Existem poucos instrumentos de medida de alta qualidade que tiveram suas propriedades adequadamente medidas. O instrumento com maior qualidade é o Muscular Dystrophy Functional Rating Scale. O Motor Function Measure (instrumento genérico), Duchenne Muscular Dystrophy Upper-limb Patient-reported Outcome Measure, North Star Ambulatory Assessment e Myotonic Dystrophy Type 1 Activity and Participation Scale for Clinical Use (específicos) também são recomendados.
RESUMEN
AIM: To identify the standardized assessment scales for people with muscular dystrophy and investigate the quality/level of evidence of their measurement properties. METHOD: A systematic review of patient-reported outcome measures was conducted on the MEDLINE, Embase, AMED, DiTA, and PsycINFO databases in August 2020. We included psychometric studies that investigated the validity, reliability, and responsiveness of instruments assessing activity and participation for muscular dystrophy of any type (Duchenne, Becker, limb-girdle, facioscapulohumeral, congenital, and myotonic) or age. Two independent reviewers selected the studies, extracted data, and evaluated the instruments' quality and level of evidence following the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. The study followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) 2020 guidelines. RESULTS: The searches identified 6675 references; a total of 46 studies with 28 condition-specific or general instruments were included. The measurement properties of most instruments had sufficient (68.8%) or indeterminate (25.7%) results according to COSMIN. The quality of evidence of the measurement properties was moderate (23.8%) or low (22.6%) according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). INTERPRETATION: There is a lack of high-quality instruments whose psychometric properties are adequately measured. The highest quality instrument is the Muscular Dystrophy Functional Rating Scale. The Motor Function Measure (general instrument), Duchenne Muscular Dystrophy Upper-limb Patient-reported Outcome Measure, North Star Ambulatory Assessment, and Myotonic Dystrophy Type 1 Activity and Participation Scale for Clinical Use (specific) are also recommended. WHAT THIS PAPER ADDS: There are 28 available instruments for activity and participation of people with muscular dystrophy. The evidence quality is moderate or low because of imprecision and indirectness. The Muscular Dystrophy Functional Rating Scale is the highest quality instrument. The Motor Function Measure is the second most recommended instrument. The Duchenne Muscular Dystrophy Upper-limb Patient-reported Outcome Measure, North Star Ambulatory Assessment, and Myotonic Dystrophy Type 1 Activity and Participation Scale for Clinical Use are also recommended.

Aims: To describe the characteristics of the most accessed YouTube videos in Brazilian-Portuguese on cerebral palsy (CP), and to analyze content of informational videos about this topic.Methods: This was a cross-sectional study. Searching on YouTube website was conducted by two independent examiners between November and December 2019, using the keywords "Paralisia Cerebral" sorted by videos' number of views. Videos that did not present content related to CP or duplicate videos were excluded. The interaction parameters and content characteristics of the included videos were extracted. To access the trustworthiness and quality of informational videos, the modified Discern checklist and the Global Quality Score was used.Results: Following the eligibility criteria 90 videos were included. Fifty-three (53) were classified as experiential videos and 37 as informational videos. Informational videos presented multi-topics about different aspects of CP. This group of videos presented moderate trustworthiness due to the lack of scientific evidence content. Informational videos had good quality and generally good flow.Conclusion: YouTube presented a large number of videos about CP in Brazilian-Portuguese. Informational videos are useful for patients and healthcare providers; however, it is necessary to included information about scientific evidence, as a strategy to facilitate and promote knowledge translation.

AIM: To identify and assess published studies concerning physical therapy in Brazilian children and adolescents with cerebral palsy (CP) using the International Classification of Functioning, Disability and Health (ICF) framework. METHOD: Articles in English and Portuguese published until October 2020, with no date restrictions, were searched in several different databases. Study characteristics, journal metrics, sample characteristics, and ICF domains explored intervention components and outcomes were extracted. Studies were classified according to the Oxford Centre for Evidence-Based Medicine hierarchy levels to characterize the evidence. RESULTS: Ninety-four studies were included. Spastic CP with fewer limitations in gross motor abilities was the most reported; 67% of the studies had low levels of evidence and were published in journals without an impact factor. The three most frequent interventions were neurodevelopmental treatment, suit therapy, and transcranial direct current stimulation. Intervention components explored body functions and structures (73.4%), activity (59.6%), environment (2.1%). They did not explore participation (0%). The outcomes investigated addressed activity (79.8%), body functions and structures (67.0%), and participation (1.1%), but not environment (0%). INTERPRETATION: Studies of physical therapy for Brazilian children and adolescents with CP focused on reducing impairments and activity limitations. Studies with higher levels of evidence and an expanded focus on participation and environmental factors are necessary.

Foram extraídos dados sobre as características do estudo, métricas do periódico, características da amostra, domínios da CIF explorados a partir dos componentes e desfechos das intervenções. Para caracterizar as evidências, os estudos foram classificados de acordo com os níveis de evidência do Centro de Medicina Baseada em Evidência de Oxford. RESULTADOS: Noventa e quatro estudos foram incluídos. Crianças com PC espástica e com menores limitações nas habilidades motoras grossas foram as mais reportadas; 67% dos estudos apresentaram baixos níveis de evidência e foram publicados em periódicos sem fator de impacto. As três intervenções mais frequentes foram o conceito neuroevolutivo Bobath/terapia do neurodesenvolvimento, a terapia com vestes e a estimulação transcraniana por corrente contínua. Os componentes das intervenções exploraram estruturas e funções do corpo (73,4%), atividade (59,6%) e ambiente (2,1%). Entretanto não exploraram a participação (0%). Os desfechos investigados abordaram atividade (79,8%), estruturas e funções do corpo (67,0%), participação (1%) e ambiente (0%). INTERPRETAÇÃO: Os estudos de intervenções fisioterapêuticas para crianças e adolescentes brasileiros com PC, apresentam maior foco em minimizar deficiências em estruturas e funções do corpo e limitações de atividades. São necessários mais estudos, com melhor nível de evidência e foco ampliado para a participação e os fatores ambientais.
RESUMEN
This study investigated the effect of sample storage duration on the quantification of oxidative stress markers in the gastrocnemius, heart, and brain of mice submitted to a maximum swimming exercise. Thiobarbituric acid reactive substances (TBARSs), protein carbonyl derivatives, total antioxidant capacity (TAC), and the activity of superoxide dismutase (SOD) and catalase (CAT) were quantified in fresh tissues and in samples stored at -80°C for 1, 3, or 6 months, from exercised (n = 13) and nonexercised mice (n = 13). Except for protein carbonyl derivatives in the heart, the exercise resulted in the modification of all markers in all fresh-evaluated samples (p < 0.001). The storage duration did not modify the effect of exercise on protein carbonyl derivatives and TAC. TBARS was stable for 3 months in the gastrocnemius and for 1 month in frozen heart and brain. Accordingly, the exercise effect on TBARS levels observed in fresh samples was absent in the gastrocnemius frozen for 6 months (p = 0.98) and in the heart and brain frozen for 3 months (p = 0.07 and 0.28, respectively) or more (p = 0.21 for heart and p > 0.99 for brain). In addition, CAT and SOD activities were reduced by storage duration in all tissues evaluated (p < 0.05). Our findings show that sample storage duration alters the quantification of oxidative stress markers in mice submitted to maximum exercise, and its effect is tissue and marker dependent. Some recommendations to achieve more accurate and reproducible data in the exercise physiology and oxidative stress markers field are presented.

This study aimed to investigate the efficacy of whole-body vibration training (WBVT) on blood brain-derived neurotrophic factor (BDNF) levels and determine the clinical and functional outcomes in patients with fibromyalgia syndrome (FMS). Thirty-two women with FMS were randomized into an intervention group (IG), receiving 6 weeks of WBVT, or a control group (CG) with no intervention. The outcomes at the baseline and follow-up in both groups included blood BDNF levels, sit-to-stand test (STS), 6-minute walk test (6MWT), Fibromyalgia Impact Questionnaire (FIQ), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and visual analogue scale (VAS). WBVT resulted in a group-by-time interaction effect. Thus, after the intervention time, the IG had increased blood BDNF levels (p=0.045), a higher number of repetitions on the STS test (p=0.011), and increased walking distance on the 6MWT (p=0.010), compared to CG. Moreover, there was a reduction in the scores of the FIQ (p=0.001), the PSQI (p=0.001), the BDI (p=0.017), and pain assessed using VAS (p=0.008) in IG. The results demonstrate that WBVT promotes an increase in blood BDNF levels, with concomitant improvement in lower limb muscle strength, aerobic capacity, clinical symptoms, and quality of life in women with FMS. This trial is registered with Brazilian Clinical Trials Registry (REBEC; RBR-38nbbx) (https://ensaiosclinicos.gov.br/rg/RBR-38nbbx).

BACKGROUND: Gross motor development curves for children with Cerebral Palsy (CP), grouped by Gross Motor Function Classification System (GMFCS) levels, help health care professionals and parents to understand children's motor function prognosis. Although these curves are widely used in Brazil to guide clinical decision-making, they were developed with Canadian children with CP. Little is known about how these patterns evolve in children and adolescents with CP in low-income countries like Brazil. The PARTICIPA BRAZIL aims to: (i) to identify and draw a profile of functioning and disability of Brazilian children and adolescents with CP by classifying them, for descriptive purposes, with all five valid and reliable functional classifications systems (gross motor function, manual ability, communication function, visual and eating and drinking abilities); (ii) to create longitudinal trajectories capturing the mobility capacity of Brazilian children and adolescents with CP for each level of the GMFCS; (iii) to document longitudinal trajectories in the performance of activities and participation of Brazilian children and adolescents with CP across two functional classification systems: GMFCS and MACS (Manual Abilities Classification System); (iv) to document longitudinal trajectories of neuromusculoskeletal and movement-related functions and exercise tolerance functions of Brazilian children and adolescents with CP for each level of the GMFCS; and (v) to explore interrelationships among all ICF framework components and the five functional classification systems in Brazilian children and adolescents with CP. METHODS: We propose a multi-center, longitudinal, prospective cohort study with 750 Brazilian children and adolescents with CP from across the country. Participants will be classified according to five functional classification systems. Contextual factors, activity and participation, and body functions will be evaluated longitudinally and prospectively for four years. Nonlinear mixed-effects models for each of the five GMFCS and MACS levels will be created using test scores over time to create prognosis curves. To explore the interrelationships among ICF components, a multiple linear regression will be performed. DISCUSSION: The findings from this study will describe the level and nature of activities and levels of participation of children and youth with CP in Brazil. This will support evidence-based public policies to improve care to this population from childhood to adulthood, based on their prognosis.

OBJECTIVE: To compare the effect of Whole-Body Vibration Exercise (WBVE) applied in push-up modified and half-squat positions, on handgrip strength (HS) and on the electromyography registry (EMGrms) of the flexor digitorum superficialis muscle (FDSM) of the dominant hand. METHODS: Nineteen healthy women (age 23.40 ± 4.03 years, bodyweight: 58.89 ± 9.87 kg), performed in a randomized order five different tests: (S1) Control; (S2) Push-up modified; (S3) Push-up placebo; (S4); Half-squatting; (S5) Half-squatting placebo. The HS and the EMGrms were assessed at baseline and immediately after the tests. ANOVA two-way design mixed test, with Tukey post hoc, was used to evaluate the HS, EMGrms and the ratio between EMGrms and HS, i.e., neural ratio (NR). Thus, the lower NR represents the greater neuromuscular modifications. The statistical significance level was set up at p < 0.05. RESULTS: WBVE on S2 increased HS compared to the stimulus applied to the S4 (p = 0.0001). The increase in HS was associated with a reduction in the EMGrms of the FDSM (p < 0.001) and a lower NR (p < 0.0001), i.e., greater neuromuscular modifications, in the S2 compared to the S4 after the tests. CONCLUSION: The distance of the stimulus and the positioning on the vibratory platform influence the maximum muscular strength due to neuromuscular modifications of hands in healthy women.
RESUMEN
OBJECTIVE: To determine the effectiveness of conservative treatment (CT) on pain and function in patients with patellar tendinopathy (PT) compared with minimal intervention (MI) or other invasive intervention, or in addition to decline eccentric squat. METHODS: Searches were performed in MEDLINE, Embase, Cochrane, PEDro, SPORTDiscus, CINAHL and AMED databases. All randomised trials that evaluated CT (any intervention not involving invasive procedures or medication) in individuals with PT were included. Two reviewers screened studies, extracted data and assessed risk of bias of all included studies. Where suitable, meta-analyses were conducted; we assessed certainty of the evidence using GRADE methodology. RESULTS: When compared with MI, CT did not improve pain (weighted mean difference (WMD) -2.6, 95% CI -6.5 to 1.2) or function (WMD 1.8, 95% CI -2.4 to 6.1) in the short-term (up to 3 months) follow-up. When compared with invasive intervention, CT did not improve pain (WMD 0.7, 95% CI -0.1 to 1.4) or function (WMD -6.6, 95% CI -13.3 to 0.2) in the short-term follow-up. No overall effects were found for combined CT (when a conservative intervention was added to decline eccentric squat) on pain (WMD -0.5, 95% CI -1.4 to 0.4) or function (WMD -2.3, 95 % -9.1 to 4.6) at short-term follow-up. Single studies showed an effect on pain with iontophoresis at short-term follow-up (d = 2.42) or dry needling at medium/long-term follow-up (d = 1.17) and function with exercise intervention at medium/long-term follow-up (over 3 months) (d = 0.83). SUMMARY/CONCLUSION: Our estimates of treatment effect have only low to very low certainty evidence to support them. This field of sports medicine/sports physiotherapy urgently needs larger, high-quality studies with pain and function among the potential primary outcomes.

PURPOSE: To investigate associations between anthropometric measures (birthweight, weight gain and current BMI) and back pain; and to determine whether these associations differ between those born with low or full birthweight. METHODS: The cross-sectional associations between the lifetime prevalence of back pain and anthropometric measures (birthweight, weight gain and current BMI) among 2754 adult twins were investigated in three stages: total sample; within-pair case-control for monozygotic and dizygotic twins together; and within-pair case-control analysis separated by dizygotic and monozygotic. Results were expressed as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Birthweight was not associated with back pain (OR 0.99; 95% CI 0.99-1.00), but a weak association was found between weight gain (OR 1.01; CI 1.00-1.01) or current BMI (OR 1.02; 95% CI 1.00-1.05) and back pain in the total sample analysis. These associations did not remain significant after adjusting for genetics. The associations did not differ between those whose were born with low or full birthweight. CONCLUSION: Birthweight was not associated with prevalence of back pain in adulthood. Weight gain and current BMI were weakly associated with back pain prevalence in the total sample analysis but did not differ between those born with low or full birthweight. However, the small-magnitude association only just achieved significance and appeared to be confounded by genetics and the early shared environment. Our results suggest that a direct link between these predictors and back pain in adults is unlikely. These slides can be retrieved under Electronic Supplementary Material.

This study aims to investigate the cardiorespiratory responses to different vibration frequencies to characterize the intensity of exercise, as well as to compare the effect of two types of squatting exercises (static and dynamic) on the whole body vibration (WBV) exercise in individuals with chronic obstructive pulmonary disease (COPD). Twenty-six subjects were divided and paired into healthy and COPD groups that performed static squatting associated with WBV (frequencies: 30, 35, and 40 Hz; amplitude: 2 mm) and dynamic squatting associated with WBV (frequency: 35 Hz; amplitude 2 mm) on a vertical vibration platform. Oxygen consumption (VÌo2), heart rate (HR), minute ventilation (VÌe), ratio of minute ventilation to oxygen production (VÌe/VÌo2), ratio of minute ventilation to carbon dioxide production (VÌe/VÌco2), oxygen saturation (SpO2), and rating of perceived exertion were measured. For both groups, there was a decrease in VÌe/VÌo2 and VÌe/VÌco2 ratios during static and dynamic squats, as well as an increase in other cardiorespiratory parameters, and no significant difference existed between them. There was an effect of the type of squat on the HR variation; the values in the static squat were higher than those of the dynamic squat in both groups. There was a significant difference with a reduction in SpO2 at 40 Hz frequency when compared with 30 Hz in the COPD group. The other variables behaved similarly between the frequencies. The WBV exercise, regardless of the frequencies used, represented a mild effort that promoted cardiorespiratory response in COPD, with greater responses in the static squat and no adverse effect. NEW & NOTEWORTHY This study showed that an acute session of light exercise of whole body vibration (WBV) can increase the cardiorespiratory responses in patients with chronic obstructive pulmonary disease (COPD), reaching values similar to that of the control group. The results might contribute, therefore, to the elaboration of exercise protocols with WBV for the treatment of patients with COPD during rehabilitation. Thus, future studies referring to training on the vibratory platform could use these exercise parameters and demonstrate possible long-term benefits.

RESUMEN
BACKGROUND: Previous studies speculated that the Incremental Shuttle Walking Test (ISWT) is a maximal test in children and adolescents, however comparison between ISWT with cardiopulmonary exercise test has not yet performed. Furthermore, there is no regression equation available in the current literature to predict oxygen peak consumption (VO2 peak) in this population. This study aimed to assesses and correlate the cardiorespiratory responses of the ISWT with the cardiopulmonary exercise (CEPT) and to develop and validate a regression equation to predict VO2 peak in healthy sedentary adolescent boys. METHODS: Forty-one participants were included in the study. In the first stage, the VO2 peak, respiratory exchange ratio (R peak), heart rate max (HR max) and percentage of predicted HR max (% predicted HR max) were evaluated in CEPT and ISWT (n = 26). Second, an equation was developed (n = 29) to predict VO2 peak. In both phases, the VO2 peak, respiratory exchange ratio R and hearth rate (HR) were evaluated. In the third stage, the validation equation was performed by another 12 participants. RESULTS: Similar results in VO2 peak (P>0.05), R peak (P>0.05) and predicted maximum HR (P>0.05) were obtained between the ISWT and CEPT. Both tests showed moderate significant correlations of VO2 peak (r = 0.44, P = 0.002) e R peak (r = -0.53, P < 0.01), as well as the agreement of these measurements by Bland-Altman analysis (VO2 peak, bias = -0.13; R peak, bias = 0.0). Distance walked was the variable that explained 42.5% (R2 = 0.425, p = 0.0001) of the variance in VO2 peak. The equation was VO2 peak (predicted) = 20.94 + (0.02 x distance walked). The results obtained by the equation were not significantly different compared to the values obtained by the gas analyzer and the Bland-Altman analysis showed agreement (bias = 1.6). CONCLUSION: The ISWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary adolescent boys.
