Abstract

Surface electromyography techniques are widely used in field of motion analysis and ergonomics combining precise muscular activation assessment with low-invasiveness and wearability. The aim of this investigation is to identify the myoelectrical manifestations of fatigue and to compare the effectiveness of sEMG-based quantitative indices for fatigue assessment. The investigated indexes are the ARV and RMS signal amplitudes, the mean frequency, the median frequency, the Dimitrov index, the instantaneous mean frequency and Wavelet distribution-based WIRE51 index. Two different protocols were developed, and the activity of the lateral deltoid and middle trapezius muscles was recorded. The WIRE51 index is found to have the highest sensitivity in the detection of the difference between the repetitions of each exercise for both protocols. Due to the lack of a unified standard for the performance comparison of fatigue indices, a correlation analysis was carried out between the result provided by the indices and the subjective fatigue perception employing the RPE scale.

基于 sEMG 信号量化肌肉疲劳的线性算法回顾与比较。

表面肌电图技术被广泛应用于运动分析和人体工程学领域，它结合了精确的肌肉激活评估、低侵入性和可穿戴性。本研究旨在确定疲劳的肌电表现，并比较基于 sEMG 的疲劳评估定量指标的有效性。研究的指标包括 ARV 和 RMS 信号幅度、平均频率、中位数频率、Dimitrov 指数、瞬时平均频率和基于小波分布的 WIRE51 指数。研究人员制定了两种不同的方案，并记录了三角肌外侧和斜方肌中部的活动。结果发现，在两种方案中，WIRE51 指数在检测每个练习重复次数之间的差异方面具有最高的灵敏度。由于缺乏统一的疲劳指数性能比较标准，我们对指数提供的结果和采用 RPE 量表的主观疲劳感进行了相关分析。

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.
