The objective of this study was to assess the effect of a passive trunk exoskeleton on functional performance for various work related tasks in healthy individuals. 18 healthy men performed 12 tasks. Functional performance in each task was assessed based on objective outcome measures and subjectively in terms of perceived task difficulty, local and general discomfort. Wearing the exoskeleton tended to increase objective performance in static forward bending, but decreased performance in tasks, such as walking, carrying and ladder climbing. A significant decrease was found in perceived task difficulty and local discomfort in the back in static forward bending, but a significant increase of perceived difficulty in several other tasks, like walking, squatting and wide standing. Especially tasks that involved hip flexion were perceived more difficult with the exoskeleton. Design improvements should include provisions to allow full range of motion of hips and trunk to increase versatility and user acceptance.
本研究旨在评估被动式躯干外骨骼对健康个体进行各种与工作相关任务时的功能表现的影响。18 名健康男性完成了 12 项任务。根据客观结果测量和主观感知的任务难度、局部和全身不适，评估了每个任务的功能表现。穿着外骨骼在外骨骼在静态前屈中倾向于提高客观表现，但在行走、搬运和爬梯等任务中表现下降。在静态前屈中，感知到的任务难度和背部局部不适明显降低，但在行走、下蹲和宽站等其他几个任务中，感知到的难度明显增加。特别是涉及髋关节屈曲的任务，佩戴外骨骼后会感觉更困难。设计改进应包括允许髋关节和躯干全范围运动的规定，以提高通用性和用户接受度。
