摘要

腰背疼痛或损伤在从事体力要求高的职业或重复性体力搬运任务的个体中很普遍,导致重大的个人和社会负担。外骨骼已经成为一项很有前途的技术,通过提供机械支持和减少对身体的物理需求来减轻受伤的风险。外骨骼供应商提供的有关其产品支持能力的信息很少,因为许多供应商没有公布这些数据。此外,目前还不清楚这些设备的行为是否会在不同的工作要求下发生变化(例如,运动速度)。本研究旨在评估外骨骼激活水平和角速度对SuitX-backX和Laevo-V2.5矢状面力矩输出的影响。为了收集数据,我们将外骨骼安装在测功机上,并以五种不同的加载速率(5、10、20、30、45和60度/秒)将其加载到全范围运动中。我们使用统计参数映射双向方差分析来比较激活水平(高/低)和角速度之间的关系。结果显示两种模型的激活水平和角速度存在显著差异。本研究旨在测量来自SuitX-backX和Laevo-V2.5的力矩输出,以确定外骨骼激活水平和角速度之间是否存在差异,从而为职业应用中特定任务的外骨骼选择提供信息。

Comparison of flexion and extension moments from passive low-back exoskeletons as a function of angular velocity
Pain or injury to the low back are prevalent among individuals engaged in physically demanding occupations or tasks involving repetitive manual material handling, resulting in significant personal and societal burdens. Exoskeletons have emerged as a promising technology to mitigate the risk of injuries by providing mechanical support and reducing the physical demand on the body. Exoskeleton providers provide minimal information related to the support capability of their product, as many do not publish these magnitudes. Further, it is currently unclear whether these device's behaviors change under varying work demands (e.g., movement velocity). This study aimed to assess the effects of exoskeleton activation levels and angular velocity on sagittal plane moment outputs from the SuitX-backX and Laevo-V2.5. For data collection, we installed exoskeletons on a dynamometer and loaded them in a full range of motion with five different loading rates (5, 10, 20, 30, 45, and 60 deg/sec). We used Statistical Parametric Mapping Two-Way ANOVAs to compare between activation level (high/low) and angular velocities. Results revealed significant differences between activation levels and angular velocities for both models. This study aimed to measure moment outputs from the SuitX-backX and Laevo-V2.5 to determine if differences existed between exoskeleton activation levels and angular velocity to inform task-specific exoskeleton selection for occupational applications.
