automatic biosignal quality analysis for surface electromyography

CleanEMG is a collaborative research project between Carleton University and the University of New Brunswick. The objective of CleanEMG is to develop an open source user-friendly software tool to perform automatic noise quantification in surface electromyography (sEMG). During analysis, such a tool enables rejection of sEMG records that contain large amounts of interference, avoiding improper conclusions being drawn from poor data. Such a tool also allows for validation of an sEMG system setup, detecting issues in the acquired sEMG (e.g., power line interference, motion artifact) and potentially identifying sources of contamination. In addition to quantifying the level of contamination, methods may be extended to enable the judicial removal of contaminants through advanced signal processing. The CleanEMG tool would remove the requirement for a trained sEMG technician for proper and reliable sEMG signal acquisition. CleanEMG will simplify sEMG data acquisition, improve its reliability, and reduce associated time and costs.
