PhysioEMG: EMG Analysis Functions for PhysioExperiment Objects

Provides electromyography (EMG) analysis functions for PhysioExperiment objects. Includes envelope extraction (RMS, Hilbert), muscle activation onset detection (Hodges-Bui, Teager-Kaiser), fatigue analysis (median frequency shift), and muscle synergy decomposition (NMF, PCA, ICA).
