Physical therapy for assessing and preventing ergonomic risks in a financial unit workers

Abstract

Physical overload, common among workers, results in increased prevalence of work-related musculoskeletal disorders (WRMD). In view of workers' health, and in order to reduce the rate of time off-work, assessment and prevention of these disorders should be emphasized. The purposes here were to analyse the ergonomics of a financial unit and its employee's postures during work, and to propose solutions that minimize ergonomic risks. The analysis was carried out by means of three observational techniques - RULA, rapid upper limb assessment, Couto's checklist, and ergonomic analysis with focus on the activity - and by applying the SF-36 questionnaire to employees. Results showed presence of moderate biomechanical factors and a risk to WRMD unlikely but possible; workplace conditions were found close to ideal. But a more detailed analysis showed working postures within the worst level, requiring immediate changes. At SF-36 scores were high, showing adequate quality of life. Thus, although work environment was found suitable, the misuse of equipment, poor distribution and incorrect way of performing tasks point to ergonomic hazards. In order to minimize risks, preventive measures were proposed, suggesting specific actions in areas that most contribute to ergonomic hazards.
