WebDec 1, 2013 · 1. Introduction. The relationship between the amplitude of surface electromyography (EMG) and the generated force, i.e., EMG–force relationship, is a simple relationship that provides a better understanding of the degree of neuromuscular activation of skeletal muscle during isometric force production. Webits size. Hence, the EMG–force relationship might be linear at small external torque/force magnitudes but is most likely nonlinear at large external torque/force magnitudes because EMG increases at a greater rate. EMG as a Research Tool Information derived from the raw EMG signal is typically limited to a frequency analysis. To analyze EMG ampli-
