Abstract

The objective of this study was to explore the effectiveness of a passive back-support exosuit at reducing low back muscle fatigue during an 18-minute trunk posture maintenance task. On two separate days sixteen participants performed an 18-minute trunk posture profile that reflected trunk flexion postures observed during a challenging vascular surgery procedure. On one day they performed the procedure with the support of the exosuit, on the other day without. Test contractions were performed every three minutes to capture the time-dependent electromyographic activity of the bilateral erector spinae muscles. Time domain (amplitude) and frequency domain (median frequency) measures of erector spinae muscle fatigue were assessed. Results revealed that the exosuit significantly reduced the measures of erector spinae muscle fatigue in terms of both amplitude (6.1%) and median frequency (5.3%), demonstrating a fatigue reduction benefit of the exosuit in a realistic surgical posture maintenance task.

量化被动式躯干支撑外衣在准静态姿势维持任务中减少竖脊肌疲劳的效果。

本研究旨在探索被动式背部支撑外衣在 18 分钟躯干姿势保持任务中减少腰背肌肉疲劳的效果。16 名参与者分别在两天内完成了 18 分钟的躯干姿势剖面图，该剖面图反映了在具有挑战性的血管手术过程中观察到的躯干屈曲姿势。其中一天，他们在外衣的支持下进行了手术，而另一天则没有外衣的支持。每三分钟进行一次收缩测试，以捕捉双侧竖脊肌随时间变化的肌电活动。对竖脊肌疲劳的时域（振幅）和频域（中值频率）测量进行了评估。结果表明，在振幅（6.1%）和频率中值（5.3%）方面，外固定衣明显降低了竖脊肌疲劳的测量值，这表明外固定衣在现实的手术姿势维持任务中具有降低疲劳的益处。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
