Effects of a passive back-support exosuit on lumbar muscle activity and passive moment under different harvesting postures and ground slopes.

Noting differences in active and passive lumbar contributions to trunk extension moment across harvesting postures and ground slopes, this study examined whether a back-support exosuit reduces tissue loads and suggests the exosuit can effectively reduce lumbar muscle activity during kneeling/squatting and passive moment during stooping, with consistent effects across slopes.
