摘要
简要介绍了定量递归分析(RecurrenceQuantificationAnalysis,RQA)方法在表面肌电信号(surfaceelectromyographic,EMG)分析中的应用进展情况。应用RQA方法对不同位置的肌电信号进行自发受力分析,得出随着力量的增加,确定性值也相应增大的结论,并且与传统的频域分析变量中值频率进行比较,得出了确定性值与中值频率的关系。对电刺激诱发表面肌电信号进行RQA分析,得出了随着刺激强度的增加,RQA参数%REC、%DET、ENTR、Trend都相应增大的结论。
This paper introduces the development of applications of recurrence quantification analysis in surface electromyographic signal.And the possible application of recurrence quantification analysis strategy to the analysis of spontaneous force of sEMG is described.The result shows the percent determination is increased along with force and compared with the median frequency and found the relation of them.Recurrence quantification analysis is used to processing the sEMG educed by the Electric stimulation time in this paper.
