As a non-invasive technique of identifying muscle activity, SEMG may be very useful. SEMG amplitude and frequency have been investigated as an indicator of muscular fatigue and to estimate muscle force and torque for the purpose of training athletes and for machine control. Many authors in the past have observed monotonically increasing relationship between RMS of SEMG with the force of contraction developed by the muscles. When the muscle is contracting to produce motion, the strength of contraction is varying and variation in SEMG is far greater during isometric contraction. The biological processes associated with the onset of muscle fatigue changes due to these different causes are believed to be different. And in turn can be different from person to person. This paper attempts to investigate on such variations in RMS of the SEMG in VL and VM muscles and the do the analysis to the results thus obtained. © 2004 IEEE.
