Do Spatial Descriptors Improve Multi-DoF Finger Movement Decoding from HD sEMG?

arXiv CS.LG

ArXi:2512.13870v4 Announce Type: replace-cross Restoring hand function requires simultaneous and proportional control (SPC) of multiple degrees of freedom (DoFs). This study evaluated the multichannel linear descriptors-based block field method (MLD-BFM) against conventional feature extraction approaches for continuous decoding of five finger-joint DoFs using high-density surface electromyography (HD sEMG). Twenty-one healthy participants performed dynamic sinusoidal finger movements while HD sEMG signals were recorded from the proximal forearm.
