Central Pattern Generator (CPG) is still an elusive concept that has a visual manifestation as a rhythmic oscillation commanded from the spine, but that also has another manifestation as a train of bursts in the surface electromyographic (sEMG) signals recorded on the para-spinal muscles. This leads to the challenging problem of correlating the visually observed spinal wave with the sEMG signals recorded during the session. This paper develops a mathematical model of the spinal wave phenomenon, which, when driven by the sEMG data, yields such visually observable features as wave nodes.
