Abstract

To test whether electromyogram (EMG) is nonlinear deterministic signal or just random noise, we analyzed four EMGs data of an adult woman. EMG is assessed with the correlation dimension (D₂), maximum Lyapunov exponent (lambda₁), approximate entropy(ApEn), recurrence plot analysis (RPA) and recurrence quantification analysis (RQA). From all the results of these assessments we can conclude that EMG obeys a certain nonlinear deterministic law and nonstationarity is significant within this signal
