DescriptionWe studied the effects of four different ASEs on kinematics and subjective assessments during simulated static overhead tasks. Ten participants completed the tasks, which involved pushing on a load cell set at three different heights, in both the forward and upward directions, and each of four ASE conditions (none, and three ASEs). Our preliminary results show that there were significant main effects of ASE on mean elbow and shoulder flexion angles, ratings of perceived exertion, and ratings of system usability. Using an ASE reduced mean elbow flexion angle by ~11º and shoulder flexion angle by ~14º. ASE use also reduced ratings of perceived exertions by ~28%. However, ratings of system usability suggest that none of the devices tested were acceptable. These results show that ASEs might change the kinematics of workers during overhead static tasks and that more efforts are needed to enhance the acceptability of these devices.
