Abstract
The current method of using processed EMG has certain limitations when one attempts to study the muscle behavior during continuous motions. In addition, since it ignores several useful information in the raw EMG signal, it was felt that these lost information may be the key to better understanding of the muscle behavior. Studies have shown that spectral Electromyography retains such useful information and have speculated that spectral EMG might provide better knowledge of the muscle activity. This study shows that the spectral EMG is sensitive to the changes in external torque and the joint velocity but not to the changes in the sampling area. The effect of performing submaximal tasks during dynamic conditions on the muscle effort is also explained by using an agonistic-antagonistic muscle model based on spectral EMG.
