Assessment of office ergonomic risks among network operation center employees using rapid office strain assessment and Nordic body map: A case study

Prolonged computer-based work and static sitting posture are common characteristics of Network Operation Center (NOC) activities. These working conditions may increase the risk of musculoskeletal disorders, particularly when workstation facilities do not support ergonomic working posture. This case study aimed to assess office ergonomic risks and identify musculoskeletal complaints among NOC employees using the Rapid Office Strain Assessment (ROSA) and Nordic Body Map (NBM) methods. The study involved eight NOC employees who performed continuous network monitoring activities for approximately eight hours per day. Data were collected through direct observation, workstation documentation, ROSA assessment, and NBM questionnaires. The ROSA results showed that all respondents had final scores ranging from 7 to 8, indicating a high ergonomic risk level that requires immediate corrective action. The NBM results showed that the most frequent and severe complaints were reported in the lower back, back, upper neck, and lower neck regions. These complaints were associated with prolonged sitting duration, non-adjustable chairs, inadequate back support, improper monitor placement, and suboptimal keyboard and mouse positioning. The findings indicate that the current workstation design does not adequately support office ergonomic principles. Improvement recommendations include workstation adjustment, provision of ergonomic chairs, proper monitor and input device positioning, regular stretching, and ergonomic awareness programs.
