Abstract
Prolonged, awkward postures among assembly line workers can lead to work-related musculoskeletal disorders (WMSDs). This study determined the prevalence of WMSDs and ergonomic risk factors among assembly line workers at an electronic parts manufacturer, and introduced a low-cost ergonomic intervention. Data were gathered by means of a questionnaire. The Rapid Upper Limb Assessment (RULA) technique was used to determine ergonomic risk factors. A low-cost intervention, designed to improve working postures was introduced. Most musculoskeletal symptoms were associated with the lower back (73.6%), wrist/ hands (71.7%), and neck (67.9%). Most (80%) of the working postures analyzed using the RULA were at action levels 3 or 4. The ergonomic intervention resulted in a significant reduction in posture scores for the neck and trunk. This indicated that the intervention helped to improve workplace ergonomics.
