ERGONOMIC RISK ASSESSMENT IN AN OFFICE ENVIRONMENT USING THE CORNELL MUSCULOSKELETAL DISCOMFORT QUESTIONNAIRE (CMDQ) AND RAPID OFFICE STRAIN ASSESSMENT (ROSA)

Abstract

Prolonged sitting and suboptimal workstation design are key contributors to musculoskeletal discomfort among office workers. This study aimed to identify ergonomic risks in a sedentary office setting, focusing on discomfort patterns and workstation design deficiencies. A mixed-methods approach was adopted involving the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and the Rapid Office Strain Assessment (ROSA). Fifty office workers completed the CMDQ, from which seven individuals with high-discomfort scores were further assessed using the ROSA method. Results indicated that the most affected body regions were the shoulders (56%), lower back (46%), and neck (44%). The ROSA evaluations revealed a high average risk score of 5.42, with poor chair ergonomics (mean score: 5.29) identified as the primary concern. Other workstation components, such as the monitor and keyboard setup, showed moderate risk levels. The study concludes that ergonomic interventions, particularly in chair design and usage, are urgently required. Recommendations include replacing non-ergonomic chairs, promoting ergonomic awareness, and incorporating physical activity into daily routines to reduce musculoskeletal risks in sedentary workplaces.
