This study investigated how the ergonomic factors, such as hand dominance and postural selection, influenced on surgical performance regarding the changes of muscle activity. Twenty novices performed two virtual laparoscopic surgical training tasks and five target muscle activities were measured. Compared with using dominant hand, surgical skills performance using non-dominant hand increased muscle activities. Muscle fatigue is more likely induced in standing position than sitting position during practice. This study suggests an emerging need to focus on hand dominance during laparoscopic surgical training to address the impact of hand discrepancy on bimanual coordination. It is also important to pay attention on postural selection during training to reduce muscle fatigue, which possibly leads to injuries.
本研究调查了诸如手的优势和姿势选择等人体工程学因素如何通过肌肉活动的变化影响手术操作。20名新手进行了两项虚拟腹腔镜手术训练任务，并测量了五项目标肌肉活动。与使用优势手相比，使用非优势手进行手术技能操作会增加肌肉活动。在练习过程中，站立姿势比坐姿更容易导致肌肉疲劳。本研究表明，在腹腔镜手术训练中，迫切需要关注手的优势，以解决手的差异对双手协调的影响。在训练过程中注意姿势选择以减少可能导致受伤的肌肉疲劳也很重要。
