Figure 1

This figure provides an example of the raw signal quality of both the surface electromyogram (upper box) and the accelerogram (mid box) recorded from the L5 left electrode site during an 80% MVC sustained back extension. In the lower box, results of the MF-EMG processing including the MF EMG values calculated for each individual epoch and those of the linear regression analysis are provided.
