论文摘要
本研究调查了被动下限外骨骼对腰部负荷的影响，并验证了生物力学分析在佩戴外骨骼时评估身体负担的有效性。十二名健康的男性参与者在三个条件下执行了一项装配任务：佩戴外骨骼时站立和高低坐着。我们主要根据从运动捕获系统和力平台获得的测量结果分析了使用肌肉骨骼模型计算出的关节压缩力。在佩戴外骨骼时，腰部关节压缩力增加了。穿着外骨骼时，对关节压缩力的分析可以确定腰部负荷的增加，这是使用传统的姿势和肌肉活动分析的。因此，基于全身肌肉骨骼模型的生物力学分析为评估试图防止肌肉骨骼疾病的外骨骼的影响提供了有价值的信息。
The present study investigated the effect of a passive lower-limb exoskeleton on lumbar load and verified the effectiveness of biomechanical analysis for evaluating the physical burden while wearing the exoskeleton. Twelve healthy male participants performed an assembly task under three conditions: standing and high and low sitting while wearing the exoskeleton. We mainly analyzed the joint compression force computed using the musculoskeletal model based on measurements obtained from a motion capture system and force platform. While wearing the exoskeleton, the lumbar joint compression force increased. Analysis of the joint compression force can determine the increase in the lumbar load when wearing an exoskeleton, which is not possible using the traditional analysis of posture and muscular activity. Therefore, biomechanical analysis based on a full-body musculoskeletal model provides valuable information in evaluating the effect of the exoskeleton that attempts to prevent musculoskeletal disorders.
