Abstract
The results of a psychophysical assessment of physical stressors associated with assembly line work involving repeated upper extremity exertions was presented. Subjects performed five combination tasks involving transferring a container along a conveyor and screw driving using a pneumatic screwdriver, with each task having a different proportion of transferring and screwdriving, and rated their perceived exertion after performing each task for 30 and 60 minutes. The lowest overall perceived exertion was seen for the task which consisted of 50% transfer and 50% screwdriving and the perceived exertion levels increased as the percentage of either task increased. The highest numbers of reports of discomfort were seen for the upper extremities, lower back/torso/buttocks, and lower legs/feet areas. The authors recommend designing upper extremity tasks to be as varied as possible to decrease perceived exertion levels.
