MUSCLE DISORDERS IN ADOLESCENT IDIOPATHIC SCOLIOSIS: LITERATURE REVIEW

ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors

Analysis of musculoskeletal changes in patients with postural roundback

OBJECTIVE: To analyze the clinical and radiographic changes in patients with postural rounded upper back. METHODS: 30 patients diagnosed with postural rounded upper back were studied, being 22 male and eight female, aged between 10 and 20 years, referred by the outpatient clinic of the Grupo de Cirurgia da Coluna of the Irmandade da Santa Casa de Misericórdia de São Paulo, SP, Brazil. Patients underwent assessment of posture, special tests to check for muscle retractions and radiographic examination to measure the curvatures of spine using the Cobb method. RESULTS/CONCLUSION: It is concluded that in the postural roundback there is a moderate increase of the thoracic kyphosis; the lumbar and cervical curvatures do not increase as a compensatory mechanism; the head appears anteriorized and the shoulder is also anteriorized and medially rotated; muscle retractions are present in the hamstrings, hip flexors, pectoralis minor and adductors of the shoulder muscles; the mobility of the lumbar spine is preserved and there is no relationship between the magnitude of thoracic curvature and the retraction of the hamstring muscles

Avaliação da confiabilidade do Método Merle d'Aubigné e Postel Modificado Evaluation of the reliability of the Modified Merle d·Aubigné and Postel Method

OBJETIVO: Avaliar a confiabilidade inter-avaliadores do Método Merle d'Aubigné e Postel Modificado. MÉTODO: Participaram do estudo 45 pacientes, com média de idade de 57,93(+13,35), submetidos à artroplastia total de quadril. Todos foram avaliados por três pesquisadores, os quais receberam treinamento para uniformizar seus critérios. Realizou-se a avaliação pelo Método Merle d'Aubigné e Postel Modificado (associação dos prefixos A, B e C), no mesmo dia de forma aleatória, e os pesquisadores não se comunicaram durante as avaliações. Para avaliação da mobilidade, foram realizados movimentos passivos do quadril e mensurados pelo goniômetro universal. A análise estatística foi tratada com o Teste de Cronbach (p<0,05 e 0,7<&#945;<1,0). RESULTADOS: Análise estatística demonstrou elevadas significância e confiabilidade inter-avaliadores para os itens: prefixo (p<0,001; &#945;=0,961), dor (p<0,001; &#945;=0,892), marcha (p< 0,001; &#945;=0,898), mobilidade (p<0,001; &#945;=0,810) e pontuação total (p<0,001; &#945;=0,917). CONCLUSÃO: Verificou-se elevada significância e confiabilidade entre os três avaliadores para todos os itens do Método Merle d'Aubigné e Postel Modificado, sugerindo que esse Método é confiável, desde que seja parametrizado seus itens e realizado o treinamento prévio dos avaliadores. Nivel de evidência II, Estudo diagnóstico.<br>OBJECTIVE: To assess the inter-evaluator reproducibility of the Modified Merle d'Aubigné and Postel Method. METHOD: Forty-five patients took part in the study, with a mean age of57.93 (±13,35) who underwent total hip arthroplasty. All were evaluated by three researchers, who received training to standardize their criteria. The evaluation was held by the Modified Merle d'Aubigné and Postel Method (association of prefixes A, B and C) the same day at random, and the researchers did not report to one another throughout the evaluations. For mobility assessment, passive hip movements were performed and measured with the universal goniometer. The statistical analysis was carried out by the Cronbach Test (p<0,05 and 0,7<&#945;<1,0). RESULTS: The statistical analysis showed significantly high inter-evaluators reliability for the items: prefix (p<0,001; &#945; = 0,961), pain (p <0,001; &#945;= 0,892), gait (p<0,001; &#945;= 0,898), mobility (p<0,001; &#945;=0,810) and total score (p <0,001; &#945;=0,917). CONCLUSION: There was high significance and reliability among the three evaluators for all items of the Modified Merle d'Aubigné and Postel Method, suggesting that this method is reliable, provided its items are parameterized and previous training of evaluators is carried out.
