A new OmniSuit study conducted by Auxivo and ETH scientists has been published in the Journal of Applied Ergonomics! The study demonstrates that the OmniSuit design can offer multi-joint support during multitask activities. Its capability to assist users' bodies throughout the entire vertical range of motion can further reduce the workload compared to single-joint exoskeletons, particularly in applications such as logistics, construction, and manufacturing.
Study Overview:
Participants and Task: 31 participants lifted a load of 2.5kg from the floor and placed it overhead, spanning the entire vertical range of motion. They performed this twice: once with the OmniSuit and once without.
Measurements: At nine positions, electromyography was used to record muscle activity in the back and shoulder muscles over the entire vertical range of motion.
Results:
The OmniSuit reduced average back muscle activity significantly by over 30% (lower back) and by over 40% (upper back) during the first phase of the task when the load was lifted from ground level to hip height.
The OmniSuit reduced average shoulder muscle activity significantly between 30 and 50% when lifting the load from belly height to overhead level.
The complete methods and results have been published in the Journal of Applied Ergonomics.
