RESUMO
Background: Osteoarthritis (OA) is the most common and prevalent musculoskeletal disease associated with population aging, negatively impacting function and quality of life. A consequence of knee OA is quadriceps muscle weakness. Musculoskeletal rehabilitation using low load exercises, associated with Blood Flow Restriction (BFR) may be a useful alternative to high load exercises when those cannot be tolerated. Several systematic reviews have reported inconclusive results due to discrepancies in study findings, heterogeneity of results, evaluated time points, and research questions explored. Objective: To perform an overview of systematic reviews with meta-analyses, synthesizing the most recent evidence on the effects of muscle strength training with BFR for knee OA. Methodology: Systematic reviews that include primary controlled and randomized clinical trials will be considered for inclusion. Articles will be considered only if they present a clear and reproducible methodological structure, and when they clearly demonstrate that a critical analysis of the evidence was carried out using instrumented analysis. Narrative reviews, other types of review, overviews of systematic reviews, and diagnostic, prognostic and economic evaluation studies will be excluded. Studies must include adults aged 40 years and older with a diagnosis of knee OA. Two authors will perform an electronic search with guidance from an experienced librarian. The following databases will be searched: PubMed via MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), PEDro, Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCO host, Web of Science, and the gray literature. The search strategy used in the databases will follow the acronym PICOS (population, intervention, comparison, outcome, and study design). Screening (i.e., titles and abstracts) of studies identified by the search strategy will be selected using Rayyan (http://rayyan.qcri.org). The quality assessment will be performed using the "Assessment of Multiple Systematic Reviews" (AMSTAR-2) tool. Systematic Review Registration: PROSPERO, CRD42022367209.
RESUMO
CONTEXTUALIZAÇÃO: A Síndrome de Marfan (SM) é uma doença autossômica dominante do tecido conjuntivo que envolve os sistemas ocular, cardiovascular e musculoesquelético, causada por mutações no gene da fibrilina1, gerando flacidez nos ligamentos articulares, favorecendo a hipermobilidade articular e redução na contenção do crescimento ósseo. OBJETIVOS: Avaliar as medidas antropométricas, alterações musculoesqueléticas e a frequência do tratamento fisioterapêutico nos pacientes com SM. MÉTODOS: Participaram deste estudo 26 pacientes, sendo 17 do gênero feminino, com idade de 13,23±2,77 anos, massa corpórea de 51,5±24-68 Kg, altura de 1,70±1,40-1,81 m e envergadura de 1,73±0,12 cm, e nove do gênero masculino, com idade de 14,44±2,18, massa corpórea de 61,0±42-72 Kg, altura de 1,83±1,66-1,97 m e envergadura de 1,93±0,13. Foram obtidas medidas antropométricas, alterações ME de forma padronizada, sendo o pectus e a escoliose, por avaliação radiológica, e a angulação (â) da curva escoliótica, pelo método de Cobb; a aracnodactilia, pelo sinal do polegar e teste de Walker-Murdoch, e a dolicostenomelia, pela envergadura em relação à altura. Os pacientes responderam a um questionário quanto à participação em tratamento de fisioterapia. RESULTADOS: Quando comparados com a estimativa brasileira, a massa corpórea e a altura apresentaram valores maiores no gênero feminino (p=0,001 e p<0,0005) e masculino (p=0,019 e p=0,0001). Das alterações musculoesqueléticas, encontrou-se pectus em 3 (11 por cento), pectus e escoliose em 19 (73 por cento), dolicostenomelia em 11 (42 por cento) e aracnodactilia em 21(80 por cento). Onze (42 por cento) pacientes com SM já haviam realizado tratamento de fisioterapia. CONCLUSÕES: As alterações antropométricas e musculoesqueléticas estão presentes na SM, e o tratamento fisioterapêutico é pouco frequente.
BACKGROUND: Marfan syndrome (MS) is an autosomic dominant condition of the connective tissue that involves the ocular, cardiovascular and musculoskeletal systems. MS is caused by mutations in the fibrillin-1 gene, leading to joint ligaments flaccidity, joint hypermobility and an overgrowth of the long bones. OBJECTIVES: The aim of the present study was to assess anthropometry, musculoskeletal alterations and the prevalence of physical therapy treatments among patients with MS. METHODS: Twenty-six patients were included in this study [17 females (age: 13.23±2.77 years; body mass 51.5±24-68 Kg; height 1.70±1.40-1.81 m; arm span: 1.73±0.12 m) and 9 males (age: 14.44±2.18; body mass: 61.0±42-72 Kg; height: 1.83±1.66-1.97 m; arm span: 1.93±0.13 m)]. Anthropometric measurements and musculoskeletal abnormalities were determined in a standardized fashion: pectus and scoliosis were assessed through radiography and angulation (â) of the scoliosis curve using the Cobb method; arachnodactyly was assessed through the thumb sign and Walker-Murdoch test and dolichostenomelia was assessed by arm span in relation to height. Patients also responded to a questionnaire addressing participation in physical therapy. RESULTS: In comparison to values estimated for the Brazilian population, mass and height were greater among the patients with MS (females: p=0.001 e p<0.0005 e males p=0.019 e p=0.0001, respectively). The following musculoskeletal abnormalities were found: pectus in 3 patients (11 percent), pectus and scoliosis in 19 (73 percent), dolichostenomelia in 11 (42 percent) and arachnodactyly in 21 (80 percent). Eleven patients (42 percent) with MS had previously undergone physical therapy. CONCLUSIONS: Patients with MS exhibit altered musculoskeleto and anthropometry and have infrequent physical therapy treatment.

OBJETIVOS: Estudar o comportamento cardiovascular e segurança frente a protocolo de exercícios de baixa intensidade em pacientes com insuficiência cardíaca (IC) grave, candidatos a transplante cardíaco. MÉTODOS: Foram estudados 21 pacientes com IC grave, inscritos na lista de transplante cardíaco do Hospital Universitário da UNIFESP. Após avaliação, os pacientes foram monitorados durante a realização de protocolo de exercício com seis fases progressivas (1º membros superiores, 2º membros inferiores, 3º caminhada 35 m, 4º ½ lance de escada, 5º caminhada de 200 m e 6º 1 lance de escada), com intensidade estimada em 2 a 6 equivalentes metabólicos (1 MET = 3,5 ml de O2/kg/min.). Os pacientes foram acompanhados prospectivamente por aproximadamente 17 meses quanto à ocorrência de complicações clínicas e óbito. RESULTADOS: Dentre os pacientes estudados, três não foram capazes de realizar o protocolo completo, sendo as variáveis índice de massa corporal (IMC), pressão respiratória máxima (Pimáx e Pemáx, cmH2O) e número de internações prévias, consideradas preditivas neste subgrupo. Frente ao protocolo de exercício, a frequência cardíaca (FC, bpm), duplo produto (DP, bpm x mmHg) e escala de percepção de esforço (EP, Borg) apresentaram maior oscilação, principalmente durante a fase 5 (H"5 METS), sendo considerados os melhores marcadores relativos ao esforço. A pressão arterial (PA, mmHg) apresentou pouca oscilação. Não houve aumento da incidência de arritmias (Kappa=0,552) frente ao esforço. Observamos correlação positiva moderada entre a EP apenas na fase 6 (caminhada de 200m), com PA (r=0,4; P=0,02). Nos pacientes com desfecho óbito, foram observados valores reduzidos de PiMax na avaliação prévia. Durante o protocolo, redução da resposta de PA e maior elevação da resposta de FC. CONCLUSÃO: O comportamento cardiovascular frente ao protocolo de exercícios foi bem tolerado e seguro, mas reforça a necessidade de monitoração. Informações obtidas na avaliação clínica inicial e durante o protocolo estão associadas com a descompensação e óbito tardio, e podem auxiliar no estadiamento destes pacientes.
OBJECTIVE: To study cardiovascular behavior and safety regarding a low-intensity exercise program for heart transplant candidates with severe heart failure. METHODS: Twenty-one patients with severe heart failure on the transplant list of the UNIFESP university hospital (Brazil) were studied. Following evaluation, the patients were monitored during an exercise program with six progressive phases (1 - upper limbs; 2 - lower limbs; 3 - walking; 4 - ½ flight of stairs; 5 - walking 200 m; and 6 - whole flight of stairs), with the intensity estimated at two to six metabolic equivalents (1 MET = 3.5 ml of O2/kg/min.). The patients were prospectively followed up for approximately 17 months for the occurrence of clinical complications and death. RESULTS: Three patients were unable to perform the complete program; BMI, maximal respiratory pressure (Pimax and Pemax, cmH2O) and number of previous hospitalizations were considered predictors for this subgroup. Heart rate (HR, bpm), double product (DP, bpm x mmHg) and Borg perceived exertion scale (PE) underwent the greatest oscillation during exercise, especially in phase 5 (H"METS), and are considered the best markers related to exertion. Blood pressure (BP, mmHg) oscillated little. There was no increase in the incidence of arrhythmia (Kappa=0.552) during exercise. There was a moderate positive correlation between PE and BP (r=0.4; P=0.02) in phase 5 (walking 200 m). The patients who died had low Pimax values upon the initial evaluation. During the exercise program, there was a reduction in BP response and an increase in HR response. CONCLUSION: Regarding cardiovascular behavior, the exercise program proved safe and well tolerated, but there is a need for monitoring. Information obtained upon the initial evaluation and during exercise program is associated to decompensation and death. Such information could assist in determining the stage of the disease.
