ABSTRACT
PURPOSE: To perform a cross-cultural adaptation and validation of the Brazilian-Portuguese versions of the Brace Questionnaire in adolescent idiopathic scoliosis. METHODS: A forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively. The Pearson's correlation coefficient was used to analyze the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire. RESULTS: A total of 84 scoliosis patients (age 13.4 ± 2.0 years, thoracic Cobb angle 33.3° ± 13.8°, and lumbar Cobb angle 29.8° ± 14.3°) were included. The Brace Questionnaire showed excellent internal consistency (Cronbach α = 0.93) and moderate reliability (ICC = 0.86). The correlations between the Brace Questionnaire and Scoliosis Research Society-22 were r = 0.66; p = 0.011. In addition, it was found that the Brazilian version of the Brace Questionnaire does not have ceiling and floor effects. CONCLUSIONS: The Brazilian-Portuguese adaptation of the brace questionnaire shows excellent reliability and can be a valid tool for psychometric assessment in adolescent idiopathic scoliosis.
ABSTRACT
Os distúrbios osteomusculares (DOM) representam as principais causas de morbidade nos trabalhadores. Estes distúrbios podem ser entendidos como um conjunto de sinais e sintomas relacionados ao trabalho, tais como dor, parestesia, fadiga e limitação da amplitude de movimento. Estas disfunções são devidas a fatores biomecânicos, sociais, psicológicos e físicos no ambiente de trabalho. Os principais fatores cinéticos funcionais associados a essas lesões são: movimentos repetitivos, força excessiva, postura inadequada, compressão e vibração mecânica das articulações. Nesse contexto, o conhecimento das características epidemiológicas, das ferramentas para avaliação do risco ergonômico e da sintomatologia osteomuscular e a realização de ginástica laboral podem contribuir para reduzir a ocorrência dos DOM. Assim, a proposta da presente revisão é demonstrar a aplicabilidade de estratégias para a prevenção dos DOM nos trabalhadores. A revisão narrativa foi realizada a partir de um levantamento nas bases de dados PubMed e BIREME. Foram incluídos estudos publicados em inglês, espanhol ou português. A prática de exercício promove benefícios tanto para as organizações quanto para os trabalhadores. As ferramentas para análise de risco de DOM são importantes para a identificação precoce dos riscos no trabalho e assim evitar consequências negativas para a saúde e os custos gerados pelo afastamento dos trabalhadores.
Musculoskeletal disorders (MSDs) are major causes of morbidity among workers. They comprise several signs and symptoms, as e.g. pain, paresthesia, fatigue and limited range of motion, which can be related to work tasks. Workplace-related factors include physical, psychological, social and biomechanical hazards. The main kinetic factors associated with MSDs include repetitive movements, exerting excessive force, awkward postures, compression and mechanical vibration. Accurate knowledge of epidemiological aspects, evaluation of ergonomic hazards and musculoskeletal symptoms, and workplace exercise may help reduce the occurrence of MSDs. The aim of the present review is to analyze the applicability of preventive strategies against MSDs among workers. We performed a narrative review based on a survey of databases PubMed and BIREME and included studies published in English, Spanish or Portuguese. We found that workplace exercise is beneficial for both employers and workers. Risk analysis of MSDs is essential for early identification of occupational hazards and to prevent health consequences and costs associated with absenteeism.
