Postural Analysis on Manual Materials Handling Tasks and Prevalence of Work-Related Musculoskeletal Symptoms Among Filipino School Transport Service Conductors

摘要

School transport service (STS) conductors, more commonly known as school bus conductors, ensure the safety and welfare of students during their travel to school, and back to their respective homes. Their tasks involve manual labor, exposing them to risks of work-related musculoskeletal disorders. Hence, it is imperative to assess and improve their working conditions. A total of 24 subjects from three different schools in Metro Manila, Philippines, with at least one year of work experience, were interviewed and observed. A modified Nordic Questionnaire was used to identify the work-related musculoskeletal symptoms (WMSSs) the conductors have experienced over the past 12 months. Postures were documented, and the corresponding risk factors were assessed using Rapid Entire Body Assessment (REBA). The results of the study showed that 91.67% of school transport service conductors have perceived WMSSs, and that majority of their work postures were categorized as having high risk levels.
