Postural Control When Using an Industrial Lower Limb Exoskeleton: Impact of Reaching for a Working Tool and External Perturbation

Benjamin Steinhilber et al.

Summary: This study investigated the impact of a lower limb exoskeleton (Chairless Chair) on postural control. It found that the exoskeleton had minimal impact when reaching for objects, but significantly increased the risk of falling when an external perturbation occurred.

Effects of back-support exoskeleton use on gait performance and stability during level walking

Jang-Ho Park et al.

Summary: This study quantified the effects of wearing a passive BSE with different levels of supportive torque on gait performance and stability during level walking. The results showed that the external torque of the BSE may adversely affect gait step width, variability, and dynamic stability. This is significant for better design and practice guidelines to facilitate the safe adoption of BSEs in the workplace.

Ergonomic Assessment of a Lower-Limb Exoskeleton through Electromyography and Anybody Modeling System

Yong-Ku Kong et al.

Summary: This study aimed to determine the muscle load reduction of the upper and lower extremities when wearing an exoskeleton. The results showed that wearing an exoskeleton reduced muscle load in the lower extremities, suggesting its potential for injury prevention.

Wearing a back-support exoskeleton impairs single-step balance recovery performance following a forward loss of balance - An exploratory study

Jang-Ho Park et al.

Summary: This study investigated the effects of wearing a back-support exoskeleton (BSE) on single-step balance recovery following a forward loss of balance. The results showed that wearing a BSE did not significantly affect the maximum lean angle from which individuals could successfully recover balance, but it increased reaction times and impeded hip and knee movements. In addition, measures of the margin of stability decreased significantly in the high-torque BSE condition.
