Background Ergonomic risk factors such as force, frequency and repetition of tasks and awkward work posture in an office environment may contribute to musculoskeletal disorders resulting in occupational injuries, work lost times and reduced work performance. This study aimed at implementing ergonomic methods to recognise risk factors and performing an educational and training intervention to eliminate risk factors and prevent the risk of musculoskeletal injury.
Methods A longitudinal study was designed to evaluate the effects of educational and training program among office employees from September 2012 to 2014. Rapid Office Strain Assessment was carried out to determine ergonomic risk factors and as a basis for intervention. Interventions based on Educational lectures, onsite training and publicity brochures. Pre and post tests were applied to participants to identify the changes after one year of intervention.
Results We found that the level of occupational health risk perception was low among employees. Adverse work postures were identified as the most common risk factors in office operations. Interventions revealed improvement in occupational health awareness, attitude and behaviour. The prevalence of musculoskeletal discomfort was reduced significantly after intervention (p<0.5).
Discussion overall, educational and training interventions showed positive effects in decreasing exposure to awkward work postures and movement. The most of employees were satisfied with the program. Our findings suggest the need for preventing intervention consisting of education and training in office ergonomics. However, Studies are needed to examine the consistent effect of interventions on the outcomes
