Abstract

Electromyography (EMG) signals are instrumental in a variety of applications including prosthetic control, muscle health assessment, rehabilitation, and workplace monitoring. Signal contaminants including noise, interference, and artifacts can degrade the quality of the EMG signal, leading to misinterpretation; therefore it is important to ensure that collected EMG signals are of sufficient quality prior to further analysis. A literature search was conducted to identify current approaches for detecting, identifying, and quantifying contaminants within surface EMG signals. We identified two main strategies: 1) bottom-up approaches for identifying specific and well-characterized contaminants and 2) top-down approaches for detecting anomalous EMG signals or outlier channels in high-density EMG arrays. The best type(s) of approach are dependent on the circumstances of data collection including the environment, the susceptibility of the application to contaminants, and the resilience of the application to contaminants. Further research is needed for assessing EMG with multiple simultaneous contaminants, identifying ground-truths for clean EMG data, and developing user-friendly and autonomous methods for EMG signal quality analysis.
表面肌电信号质量分析技术综述
肌电图(EMG)信号在各种应用中发挥着重要作用,包括假肢控制、肌肉健康评估、康复和工作场所监测。包括噪声、干扰和伪影在内的信号污染物会降低EMG信号的质量,导致误解;因此,重要的是在进一步分析之前确保所收集的EMG信号具有足够的质量。进行文献检索,以确定检测、识别和量化表面肌电信号中污染物的当前方法。我们确定了两种主要策略:1)自下而上的方法来识别特定且特征良好的污染物,2)自上而下的方法来检测高密度EMG阵列中的异常EMG信号或异常通道。最佳类型的方法取决于数据收集的环境,包括环境、应用程序对污染物的易感性以及应用程序对污染的弹性。需要进一步的研究来评估具有多种同时污染物的肌电图,确定干净肌电图数据的基本事实,并开发用户友好和自主的肌电图信号质量分析方法。

期刊介绍: IEEE Reviews in Biomedical Engineering (RBME) serves as a platform to review the state-of-the-art and trends in the interdisciplinary field of biomedical engineering, which encompasses engineering, life sciences, and medicine. The journal aims to consolidate research and reviews for members of all IEEE societies interested in biomedical engineering. Recognizing the demand for comprehensive reviews among authors of various IEEE journals, RBME addresses this need by receiving, reviewing, and publishing scholarly works under one umbrella. It covers a broad spectrum, from historical to modern developments in biomedical engineering and the integration of technologies from various IEEE societies into the life sciences and medicine.
