Humantech certified ergonomist Blake McGowan shares the results of a study that quantified the impact of wearing an upper-extremity exoskeleton on low back forces in this month’s video.
In summary, wearing an upper-extremity exoskeleton:
- increases muscle forces of the low back by approximately 50%.
- increases joint compression and shear forces by approximately 33% and 20%, respectively.
- were found to be uncomfortable and people preferred not to use them.
