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.
摘要：
这项研究系统地研究了在不同重量条件和负载位置下，被动臂支撑外骨骼（ASE）对负载保持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轮廓之间的关系。使用3（外骨骼干预）×3（重量条件）×3（负载位置）受试者内设计，研究发现，与不佩戴外骨骼和停用支撑相比，在所有情况下佩戴带支撑力的ASE显著减少了17.84%和15.19%的姿势摇摆。分别。这些改进与主观评估是一致的。稳定性优势随重量和负载位置而变化，反映外骨骼的支撑力轮廓。总的来说,研究表明，ASE的支撑力可以增强静态姿势平衡，有效性取决于重量条件和负载位置。这凸显了被动ASE在工作环境中提高稳定性和降低跌倒风险的潜力。
