Prevalence of Work Related Musculoskeletal Disorders and Quantification of Ergonomic Hazards Among Optometrists In Chennai- A Cross Sectional Study
Year: 2025
Type: article
Study design: Observational Study
Abstract: Introduction: Optometrists have to perform precision-based clinical tasks, which often require prolonged static sitting, sustained awkward postures, and repetitive movements. These frequent biomechanical demands can lead to work-related musculoskeletal disorders (WMSDs). Despite high prevalence of WMSDs globally, very limited research is available for Indian optometrists, particularly, among those who are working in tertiary eye care hospital. Thus, this present study aimed to determine the prevalence of work-related musculoskeletal disorders (WMSDs) and to quantify working posture-related ergonomic risks among optometrists in a high-volume tertiary eye care setting. Methods: A cross-sectional observational study was conducted in July, 2025 at five departments of a tertiary eye care hospital, Chennai. Ergonomic risks were evaluated using direct observation, videography, workstation measurements, the Nordic Musculoskeletal Questionnaire (NMQ), and Rapid Upper Limb Assessment (RULA). Results: The chronic prevalence of discomfort was neck flexion (>20° for 45 ± 12 min/hour) and prolonged shoulder elevation were common. Over 70% of participants lacked formal ergonomic training and reported fatigue within 2–3 hours of continuous clinical work. Conclusion: This study is an evidence of existing scenario, and study findings will help future researchers to plan intervention strategies.
