Abstract

This study systematically investigated the influence of a passive arm-support exoskeleton (ASE) on static postural balance in load-holding tasks under different weight conditions and load locations, and the relationship between such influence and the exoskeleton's supportive force profile. Using a 3 (exoskeleton interventions) ×3 (weight conditions) ×3 (load locations) within-subjects design, the research found that wearing ASE with supportive force significantly reduced postural sway by 17.84% and 15.19% across all conditions compared to without wearing the exoskeleton and with deactivated support, respectively. These improvements were consistent with subjective assessments. The stability benefits varied with the weight and load location, reflecting the exoskeleton's supportive force profile. Overall, the study suggests that the supportive force from the ASE can enhance static postural balance, with effectiveness dependent on weight conditions and load locations. This highlights the potential of passive ASEs for improving stability and reducing fall risks in work environments.

被动手臂支撑外骨骼对负重任务中静态姿势平衡的影响：支撑力、重量和负重位置的影响。

本研究系统地调查了在不同重量条件和负载位置下，被动手臂支撑外骨骼（ASE）对负重任务中静态姿势平衡的影响，以及这种影响与外骨骼支撑力曲线之间的关系。研究采用 3（外骨骼干预）×3（重量条件）×3（负载位置）的受试者内设计，发现在所有条件下，与未穿戴外骨骼和停用支撑相比，穿戴带有支撑力的 ASE 可显著减少姿势摇摆，分别减少了 17.84% 和 15.19%。这些改善与主观评估结果一致。稳定性优势随重量和负载位置的不同而变化，这反映了外骨骼的支撑力曲线。总之，研究表明，外骨骼的支撑力可以增强静态姿势平衡，其有效性取决于体重条件和负载位置。这凸显了被动式外骨骼在提高稳定性和降低工作环境中跌倒风险方面的潜力。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
