高密度阵列式肌电信号在体育领域中的应用综述

Application Summary of High-Density Array EMG Signal in Sports Field

高密度阵列式表面肌电采集系统是采用二维矩阵式表面电极覆盖于整块肌肉皮肤区域,以采集并记录骨骼肌生物电信号的测定方法,由于其便携、无创、可视化等特点,被广泛应用到体育领域。通过对高密度阵列式表面肌电的工作原理、指标分析、数据处理以及在体育领域中的应用综述表明,高密度阵列式表面肌电解决了传统表面肌电信噪比低的问题,可提供骨骼肌发力可视化图,且由于其无创、易于被受试者接受等原因,被逐步应用到在肌纤维传导速度测定、运动动作分析、肌肉力量评估和运动单位数目估计等方面。其缺点是多通道肌电测定带来的数据冗余,数据分解和数据处理工作较难,因此未来需要更多关于肌电数据处理的算法研究解决该问题。

The high-density array surface electromyography acquisition system is a measurement method that uses a two-dimensional matrix surface electrode to cover the entire muscle skin area to collect and record bioelectrical signals of skeletal muscles, which is widely used in the sports field because of its portable, non-invasive, visual, and other characteristics. The summary of the working principle, index analysis, data processing, and applications of high-density array surface electromyography in the field of sports shows that high-density array surface electromyography solves the problem of low signal-to-noise ratio of traditional surface electromyography provides visualization maps of skeletal muscle power generation, and is gradually applied to muscle fiber conduction velocity measurement, movement analysis, muscle strength evaluation, and motor unit number estimation since it is non-invasive and easy to be accepted by the subjects. Its disadvantage is the data redundancy caused by multi-channel EMG measurement,and the data decomposition and data processing are difficult. Therefore, more research on the algorithm for EMG data processing is needed in the future to solve this problem.
