PhysioHDEMG: High-Density Surface EMG Motor-Unit Decomposition for the Physio Ecosystem
Decomposition of high-density surface electromyography (HD-sEMG) electrode-grid recordings into constituent motor-unit discharge patterns by convolutive blind source separation (extension, whitening and a fixed-point contrast maximisation with convolution-kernel-compensation refinement), following Holobar & Zazula (2007) and Negro et al. (2016). Provides motor-unit pulse trains, firing statistics (discharge rate, recruitment / derecruitment, pulse-to-noise ratio and silhouette quality), spatial motor-unit action-potential maps over the electrode grid, and a ground-truth HD-sEMG simulator for validation.
