Abstract

Musculoskeletal disorders (MSDs) are prevalent under poor working situations. Where it is not possible to remove the root cause of MSDs, passive exoskeletons could be a solution. In this randomised cross-over field study we investigated the effect of a passive arm-support exoskeleton. Ten participants, recruited from a Dutch gas company, were measured with and without exoskeleton assessing muscle activity, heart rate (HR), arm elevation, and reported about their experiences. Participants spent more time in high arm elevation levels with the exoskeleton than without. Muscle activity was lower in the trapezius (Beta: -1.8 [-3.1; -0.4]) and deltoid (Beta: -1.4 [-2.3; -0.6]) muscles, but not the biceps muscle, during the measurements with exoskeleton than without, suggesting effectiveness of the exoskeleton. HR and discomfort did not statistically significantly differ between the two conditions. Participants would recommend an exoskeleton to their colleagues, but mainly for repetitive work. Their opinions about the usefulness during work varied.

使用被动式手臂支撑外骨骼工作对野外任务中客观和自我报告测量结果的影响--随机交叉研究。

在恶劣的工作环境下，肌肉骨骼疾病（MSD）十分普遍。在无法从根本上消除 MSD 的情况下，被动式外骨骼可能是一种解决方案。在这项随机交叉实地研究中，我们调查了被动式手臂支撑外骨骼的效果。我们从荷兰一家天然气公司招募了 10 名参与者，分别对他们穿戴和不穿戴外骨骼时的肌肉活动、心率（HR）和手臂抬高情况进行了测量，并报告了他们的体验。与未穿戴外骨骼的人相比，穿戴外骨骼的人手臂处于高抬高状态的时间更长。使用外骨骼时，斜方肌（Beta：-1.8 [-3.1; -0.4]）和三角肌（Beta：-1.4 [-2.3; -0.6]）的肌肉活动低于未使用外骨骼时，但肱二头肌的肌肉活动低于未使用外骨骼时，这表明外骨骼很有效。两种情况下的心率和不适感在统计学上没有明显差异。参与者会向同事推荐外骨骼，但主要用于重复性工作。他们对外骨骼在工作中的实用性看法不一。

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.
