Evaluation of Drivers Seating Posture by REBA Analysis

Abstract

This study undertakes a comprehensive assessment of driver seating posture and ergonomic risks using the Rapid Entire Body Assessment (REBA) methodology. Thirty drivers from Telangana, India, without pre-existing musculoskeletal conditions, were analyzed to determine the ergonomic risk levels associated with their driving postures. Using photographic documentation and AUTOCAD software for poster angle measurement, the REBA scoring system highlighted areas of concern, mainly focusing on the wrists, trunks, and upper arms. Results indicated that most drivers (90%) fall into a medium-risk category, with scores ranging from 4 to 7, suggesting a significant need for ergonomic intervention. The remaining 10% exhibited lower risk levels yet pointed to the need for improvement. This study reinforces the need for ergonomic enhancements to reduce the risk of musculoskeletal disorders, suggesting interventions such as seat and control redesigns and educational programs to promote safe driving postures. The findings serve as an urgent call for improving vehicle design ergonomics to enhance drivers' occupational health and safety. Keywords: Seating posture, Rapid Entire Body Assessment (REBA), AUTOCAD
