Figure 4

Transversal arrangement of signals. Transversal arrangement—signals are taken in the top-down (odd columns) and bottom-up (even columns) sequence from the electrode matrix. Rows are parallel to the longitudinal axis of the muscle. The beginning of the sequence and its end are indicated by triangles and the words “start” and “finish”. Arrows indicate how single-differential signals are taken as the differences between adjacent electrodes, which are represented by points. Each electrode corresponds to a monopolar signal. The image is formed by positioning one signal above the other, in the same sequence that they are taken from the electrode matrix.
