Abstract
EMG imaging is the focus of this chapter. The concepts of instantaneous two-dimensional potential distribution and image interpolation are discussed with respect to sEMG potential maps generated by fusiform or pinnate muscles. Sequences of images forming “movies” that reflect the generation and propagation of motor unit action potentials, as well as anatomical information concerning the location of the innervation zone, are annotated in order to illustrate how the underlying muscle anatomy and physiology can be unveiled by suitable processing of the sEMG collected with a 2D array of electrodes.
