ABSTRACT
Low back pain (LBP) and spine disorder are common problems for occupational drivers. For home delivery drivers, the Manual Materials Handling (MMH) task is the main risk factor that causes low back problems. The purpose of this study was to investigate the correlations between low back problems, and physical, biomechanical as well as psychosocial factors for the home delivery drivers. A total of 32 male home delivery drivers participated in the study. Two questionnaires including subjective musculoskeletal discomfort rating and job stress questionnaire were used. Besides, a rehabilitation doctor diagnosed the subjects' spine disorder (L5/Sl spine disc space narrowing degree) based on lumbar x-ray results. Furthermore, the biomechanical loadings of spine of twenty drivers while performing the MMH task were analyzed. The study results show that the prevalence of L5/Sl spine disc disorder among the home delivery drivers is 25%.
