The aim of this study was to determine the muscle load reduction of the upper extremities and lower extremities associated with wearing an exoskeleton, based on analyses of muscle activity (electromyography: EMG) and the AnyBody Modeling System (AMS). Twenty healthy males in their twenties participated in this study, performing bolting tasks at two working heights (60 and 85 cm). The muscle activities of the upper trapezius (UT), middle deltoid (MD), triceps brachii (TB), biceps brachii (BB), erector spinae (ES), biceps femoris (BF), rectus femoris (RF), and tibialis anterior (TA) were measured by EMG and estimated by AMS, respectively. When working at the 60 cm height with the exoskeleton, the lower extremity muscle (BF, RF, TA) activities of EMG and AMS decreased. When working at the 85 cm height, the lower extremity muscle activity of EMG decreased except for TA, and those of AMS decreased except for RF. The muscle activities analyzed by the two methods showed similar patterns, in that wearing the exoskeleton reduced loads of the lower extremity muscles. Therefore, wearing an exoskeleton can be recommended to prevent an injury. As the results of the two methods show a similar tendency, the AMS can be used.
本研究旨在通过肌电图（EMG）分析和 AnyBody 建模系统（AMS）分析，确定穿戴上肢和下肢外骨骼可减少的肌肉负荷。20 名 20 多岁的健康男性参与了这项研究，他们在两种工作高度（60 和 85 厘米）下进行了螺栓固定任务。通过 EMG 测量了斜方肌上部（UT）、三角肌中部（MD）、肱三头肌（TB）、肱二头肌（BB）、竖脊肌（ES）、股二头肌（BF）、股直肌（RF）和胫骨前肌（TA）的肌肉活动，并通过 AMS 分别对其进行了估计。当以 60 厘米的高度穿戴上肢外骨骼工作时，EMG 和 AMS 测量的下肢肌肉（BF、RF、TA）活动减少。当在 85 厘米的高度工作时，除了 TA，EMG 测量的下肢肌肉活动减少，除了 RF，AMS 测量的下肢肌肉活动减少。两种方法分析的肌肉活动表现出相似的模式，即穿戴上肢外骨骼可减少下肢肌肉的负荷。因此，可以推荐穿戴上肢外骨骼来预防受伤。由于两种方法的结果表现出相似的趋势，因此可以使用 AMS。
