Summary: Exoskeleton assistance can reduce metabolic cost and increase preferred walking speed, with individual outcomes varying. This study investigates the effects of a powered ankle exoskeleton on step regulation and its relationship to gait parameters. The results show that the response to assistance is closely related to the stepping strategy, especially in the initial learning stages.

Summary: This paper presents a smart textile-actuated spine assistance robotic exosuit (SARE) that seamlessly conforms to the back and allows for free movement, while also monitoring and rectifying human posture. Experimental results with human subjects show that the SARE can effectively reduce muscle strain, electromyography signals, and metabolic energy cost associated with repetitive lifting tasks.

Summary: This study compared walking in post-stroke patients with and without exosuit assistance. It was found that exosuit-assisted walking can improve gait deviations commonly seen in stroke patients, such as paretic propulsion and ground clearance during swing. No changes in leg muscle activity were observed, suggesting the need for further research on the potential of exosuits as a tool for gait training in stroke rehabilitation.

Summary: Slowing the decline in walking mobility in the elderly is crucial. This study investigated the effects of untethered ankle exoskeleton assistance on stability and balance strategies during walking in older adults. The findings suggest that ankle exoskeleton assistance does not impair stability and supports further research on assistive exoskeletons for walking in the elderly.

Summary: This study evaluated the effects of a portable ankle exosuit on continuous comfortable overground walking in individuals with chronic hemiparesis. The results showed that the exosuit assistance significantly improved gait impairments without increasing muscle effort, instability, or energy cost of transport. This suggests that the exosuit has great potential for rehabilitative gait training in poststroke individuals.
