Comparative Study of Ergonomic Hazards and Musculoskeletal Disorders Syndrome (MSDs) Among Bus Drivers in UiTM Shah Alam and Section 17 Shah Alam Terminal Bus

Abstract

This study investigates the ergonomic hazards and prevalence of musculoskeletal disorders (MSDs) among bus drivers at UiTM Shah Alam and Section 17 Shah Alam Terminal. Bus drivers frequently experience prolonged sitting, repetitive motions, awkward postures, and exposure to whole-body vibrations, leading to significant health risks, particularly MSDs. Globally, MSDs are among the leading occupational health issues, causing pain, reduced productivity, and even disability. Drivers' tasks, such as steering, gear shifting, and braking, often exacerbate physical strain on muscles and joints. Additionally, external factors like road conditions, long working hours, and inadequate rest breaks contribute to ergonomic risks. By identifying and comparing these risks between two groups of bus drivers, this study seeks to provide actionable insights to improve occupational health and reduce MSD prevalence.
