The study of lumbar muscle activity using isoforce maps

The concept of isoforce curves and their application to the muscle activity surfaces of the lumbar muscles is introduce. The isoforce curves are constructed from data generated by a biomechanical model of the lumbar musculature. When plotted together, the isoforce curves become contour plots of the muscle activity surfaces. On the basis of contour plots, new verification techniques are suggested and methods of developing an EMG-force relationship are explored.<>
