Introduction Prolonged standing during surgery is a cause of musculoskeletal disorders in surgeons. Wearable chairs have reportedly reduced musculoskeletal strain effectively when used in industry. However, discomfort and instability issues may remain. This study examines whether using a wearable chair for surgical procedures imposes negative effects, such as mental or physical strain on surgeons prior to its clinical implementation. Methods This prospective cross-over study compared mental strain and subjective sensations in simulated suturing tasks with and without using Archelis®, a wearable chair (Archelis Inc, Yokohama, Japan). Six surgeons participated in the study. Mental strain was examined using heart rate variations calculated during tasks. Four subjective sensations (fatigue, comfort, balance, and workability) after each task and differences in body localized pain pre- and post-task were compared using a 10 centimetres (cm)-visual analog scale (VAS) score questionnaire. Results Results showed no significant differences in mental strain nor subjective sensations with or without the wearable chair. The mean VAS scores for all four subjective sensations with the wearable chair were relatively positive. There was a slight yet insignificant post-task increase in VAS mean scores for body-localized pain in the lower legs. Conclusions Significant negative effects on surgeons from the wearable chair were not observed during simulated suturing procedures. This demonstrates no major barriers in the initial phases of wearable chairs integration into the surgery environment.
引言 手术过程中长时间站立是外科医生肌肉骨骼疾病的一个原因。据报道，可穿戴座椅在工业领域使用时能有效减轻肌肉骨骼劳损。然而，不适感和稳定性问题可能仍然存在。本研究旨在探讨在临床应用前，使用可穿戴座椅进行手术操作是否会对外科医生造成负面影响，如精神或身体上的压力。方法 这项前瞻性交叉研究比较了在模拟缝合任务中，使用可穿戴座椅Archelis®（日本横滨的Archelis公司生产）和不使用该座椅时的精神压力和主观感受。六名外科医生参与了该研究。通过计算任务期间的心率变化来检测精神压力。使用10厘米视觉模拟量表（VAS）评分问卷比较每项任务后的四种主观感受（疲劳、舒适度、平衡感和可操作性）以及任务前后身体局部疼痛的差异。结果 结果显示，使用或不使用可穿戴座椅时，精神压力和主观感受均无显著差异。使用可穿戴座椅时，所有四种主观感受的平均VAS评分相对较高。小腿部位身体局部疼痛的VAS平均评分在任务后略有增加，但不显著。结论 在模拟缝合过程中，未观察到可穿戴座椅对外科医生有显著的负面影响。这表明在将可穿戴座椅整合到手术环境的初始阶段没有重大障碍。
