高密度阵列式肌电信号在体育领域中的应用综述ApplicationSummaryofHigh-DensityArrayEMGSignalinSportsField曹春霞，王瑞元*CAOChunxia，WANGRuiyuan*摘要：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。关键词：高密度阵列式表面肌电；运动康复；空间域；等高线图Abstract:Thehigh-densityarraysurfaceelectromyographyacquisitionsystemisameasure‐mentmethodthatusesatwo-dimensionalmatrixsurfaceelectrodetocovertheentiremuscleskinareatocollectandrecordbioelectricalsignalsofskeletalmuscles,whichiswidelyusedinthesportsfieldbecauseofitsportable,non-invasive,visual,andothercharacteristics.Thesum‐maryoftheworkingprinciple,indexanalysis,dataprocessing,andapplicationsofhigh-densityarraysurfaceelectromyographyinthefieldofsportsshowsthathigh-densityarraysurfaceelec‐tromyographysolvestheproblemoflowsignal-to-noiseratiooftraditionalsurfaceelectromyog‐raphyprovidesvisualizationmapsofskeletalmusclepowergeneration,andisgraduallyappliedtomusclefiberconductionvelocitymeasurement,movementanalysis,musclestrengthevalua‐tion,andmotorunitnumberestimationsinceitisnon-invasiveandeasytobeacceptedbythesubjects.Itsdisadvantageisthedataredundancycausedbymulti-channelEMGmeasurement,andthedatadecompositionanddataprocessingaredifficult.Therefore,moreresearchontheal‐gorithmforEMGdataprocessingisneededinthefuturetosolvethisproblem.Keywords:high-densityarraysurfaceelectromyography;sportsrehabilitation;spatialdomain;contourmap中图分类号中图分类号：G804.2文献标识码文献标识码：A表面肌电图（...
