||The objective of this study was to quantify exposures to musculoskeletal disease (MSD) risk factors as a function of vehicle rotation angle and position during assembly tasks. The study was conducted at the Center for Occupational Health in Automotive Manufacturing (COHAM) Laboratory. Twelve subjects participated in the study. The vehicle was divided into seven regions, (three interior, two underbody and two engine regions) representative of work areas during assembly. Three vehicle rotation angles were examined for each region. Exposure was assessed on the spine loads and posture, shoulder posture and muscle activity, neck posture and muscle activity as well as wrist posture. In all regions, rotating the vehicle reduced musculoskeletal exposure. In five of the seven regions, 45░ of vehicle rotation represented the position that reduced MSD exposure most. Two of the seven regions indicated 90░ of vehicle rotation had the greatest impact for reducing MSD exposure. This study demonstrated that vehicle rotation shows promise for reducing exposure to risk factors for MDS during automobile assembly tasks.
