Avaliação da sensação de desconforto e de dor durante a postura sentada: uma análise em terminais informatizados.

Abstract

Contributions from various areas of knowledge makes the occupational health a focal point in the national manufacturing industry, clarifying certain matters of unusual interest in today's society, thus the order of postural disorders has been considered a serious public health problem, because reach a high incidence of economically active population worldwide, disabling it temporarily or permanently to certain professional activities. The practical relevance of this research is directed to the attention of office chairs produced in Brazil, as well as the study of worker-seat interface during the implementation of occupational activity performed in the sitting posture, and may be directed to the aid of the acquisition of furniture office, reducing the risks of disorders in employees who perform computer activity. Regarding the practical goals of this research are concerning the assessment of dimensions and design make it a suitable chair for development work in the Coordenação de Análise Documental (CODOC), located in this sector Superintendência da Zona Franca de Manaus (SUFRAMA) . Understand the theory that defines the dimensions and design of a chair at the workstation computer; consideration of the levels of comfort and discomfort during the implementation of computerized work activity, identifying the types of chairs available for the labor in the PIM; measure comfort levels during performance of work activity computerized, with two models of chairs available in SUFRAMA CODOC sector. Analyze the existence of correlation with the pathophysiology acquired during the workday and the RSI. The study was conducted via a structured interview, based on research from Iida (1998) and Guimarães (2001), in order to evaluate the sensation of discomfort and pain in seventy-one (71) employees, and forty-five ( 45) were females, representing 63%. And twenty-six (26) corresponding to 37% male, the mean age is 27.5% for women and 35.8% for men; officials had different levels of academic instruction, not being a factor variable for the research. This study, on the nature, is classified as applied, since it is oriented to the generation of knowledge driven solutions to specific problems of selection of chairs to work on computer terminals. Regarding the approach, it is a qualitative and quantitative, considering both the statistical analysis of data measured in opinion as to the scale of spontaneous individuals involved in the research, now in relation to their goals as the criteria for classification of Gil (1991 ), this research is classified as exploratory, because it aims to provide greater familiarity with the problem of evaluation of chairs for computer terminals. By obtaining the ranking, there was a preference swivel chair without armrests, curved lumbar support, height adjustment and having depth of the seat and backrest.
