Introduction: It is widely accepted that pathophysiological changes to the central nervous system of persons with Parkinson’s disease (PD) result in negative effects on motor function. However, less information is known regarding the pathology of P

Decomposition of the surface electromyographic (sEMG) signal is commonly used to examine motor unit (MU) firing behavior. However, the intra- and inter-day reliability of these measurements has yet to be quantified or reported. This investigation 1)
