摘要

表面肌电图是一种重要而广泛应用的生物医学测量技术。在生物医学工程中,获取高质量的肌电图数据并对其进行实时处理具有挑战性。另一方面,它们的校准可重复性和可靠性仍在讨论中。此外,肌电系统的计量要素尚未得到研究。在本研究中,开发了一种便携式肌电信号采集模块,并研究了四种日常手部运动的两种肌电信号特征的不确定性。此外,在受控环境下进行了仪器间比较。在多次试验中,对10个人的结果进行了估计。在设计实验时,考虑了两个主要的不确定性因素,肌肉选择/电极放置和主观分析。开发的系统的仪器间性能与现有系统相似(p值> 0.05)。开发的系统的总不确定度在RMS的0.0106-0.0196% (p值> 0.05)和MF的0.1001-0.2084% (p值> 0.05)之间。相比之下,现有商业系统的RMS不确定性为0.0171-0.0359% (p值> 0.05), MF不确定性为0.1010-0.2088% (p值> 0.05)。所开发的肌电信号采集系统的性能和成本效益验证了其在低成本产品开发中的实用性和可接受性。

Development and Uncertainty Assessment of Low-Cost Portable EMG Acquisition Module

Development and Uncertainty Assessment of Low-Cost Portable EMG Acquisition Module

Surface electromyography is an important and widely used biomedical measurement technique. In biomedical engineering, obtaining high-quality EMG data and processing it in real-time is challenging. Their calibration repeatability and reliability, on the other hand, remain in discussion. Furthermore, the metrological elements of EMG systems have not yet been studied. In this research work, a portable EMG acquisition module has been developed, and the uncertainty of two EMG characteristics for four everyday hand motions has been investigated. Furthermore, an inter-instrument comparison has been carried out in a controlled environment. For multiple trials, the result has been estimated for 10 people. While designing the experiment, two major uncertainty factors, muscle selection/electrode placement and subjective analysis, have been taken into consideration. The developed system's inter-instrument performance has been found to be similar to that of the existing system (p-value > 0.05). The total uncertainty of the developed system has been found to be in the range of 0.0106–0.0196% (p-value > 0.05) for RMS and 0.1001–0.2084% (p-value > 0.05) for MF. The existing commercial system, in contrast, exhibited uncertainty in the range of 0.0171–0.0359% (p-value > 0.05) for RMS and 0.1010–0.2088% (p-value > 0.05) for MF. The developed EMG acquisition system's performance and cost-effectiveness validate its utility and acceptability for low-cost product development.
