Electromyographic analysis of the extending muscles of the knee during functional activities.
The purpose of this study is to analyze the behavior of electrical activity of the muscles vastus medialis oblique (VMO), vastus medialis long (VML), and, rectus femoris (RF) during functional activities. The electromyography of the VMO, VML and RF muscles were analyzed in ten healthy volunteers. Signs were collected through superficial electrodes and a electrogoniometer, connected to a signal condition module. The analysis of the results after treating the signals shows us that there is a similar electromyographical behavior in the three studied muscles. Therefore, these discoveries suggest a common electrical behavior pattern especially between VMO and VL muscles in healthy volunteers.
