Avaliação de programa para reduzir dores nas costas em trabalhadores de enfermagem

OBJECTIVE: To evaluate the effectiveness of a program designed to reduce back pain in nursing aides. METHODS: Female nursing aides from a university hospital who had suffered episodes of back pain for at least six months were included in the study. Participants were randomly divided into a control group and an intervention group. The intervention program involved a set of exercises and an educational component stressing the ergonomic aspect, administered twice a week during working hours for four months. All subjects answered a structured questionnaire and the intensity of pain was assessed before and after the program using a visual analogue scale (VAS). Student's t-test or the Wilcoxon Rank Sum Test for independent samples, and Chi-square test or the Exact Fisher test for categorical analysis, were used. The McNemar test and the Wilcoxon matched pairs test were used to compare the periods before and after the program. RESULTS: There was a statistically significant decrease in the frequency of cervical pain in the last two months and in the last seven days in the intervention group. There was also a reduction in cervical pain intensity in the two periods (2 months, 7 days) and lumbar pain intensity in the last 7 days. CONCLUSIONS: The results suggest that a program of regular exercise with an emphasis on ergonomics can reduce musculoskeletal symptoms in nursing personnel.OBJETIVO: Avaliar o efeito de um programa na redução de dores nas costas em auxiliares de enfermagem. MÉTODOS: Participaram do estudo auxiliares de enfermagem com menos de 50 anos de idade, do sexo feminino, de um hospital universitário e que apresentavam dores nas costas por um período mínimo de 6 meses. O programa envolveu parte educativa, com abordagem ergonômica, e a realização de exercícios executados durante o horário de trabalho, duas vezes por semana, em um período de quatro meses. As participantes foram divididas aleatoriamente em grupo tratado e grupo controle. A intensidade das dores foi avaliada pela escala visual analógica. Foram utilizados os testes t de Student ou de Wilcoxon, para amostras independentes e os testes Qui-quadrado ou Exato de Fisher, para as categóricas. Para comparar as proporções do início e final do programa utilizou-se o teste de McNemar. RESULTADOS: Ocorreu diminuição estatisticamente significativa na freqüência de dor cervical durante os últimos dois meses e durante a ultima semana no grupo tratado. Houve também redução na intensidade da dor cervical em ambos os períodos (2 meses; 7 dias) e da dor lombar na última semana. CONCLUSÕES: O estudo sugere que programa regular de exercícios, acompanhado por abordagem instrucional ergonômica, pode reduzir sintomas músculo-esqueléticos em trabalhadores de enfermagem.35636
