title: Test nonlinear determinacy of Electromyogram.
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 (D<inf>2</inf>), maximum Lyapunov exponent (&#955;<inf>1</inf>), 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.
