Source Characteristics from Inverse Modeling of EMG Signals
If one tries to solve the inverse problem in single fiber electromyography (SFEMG), the question is which signal to consider as the proper source signal. Often the intracellular action potential (IAP) is taken as such. Measuring shape parameters and distances of Single Fiber Action Potentials and active fibers in muscle and comparing them with muscle structure model predictions reveals that it is transmembrane current which is the true source of the SFEMG.
