View Full Version : Normalizing methods of the EMG signal

02-06-2010, 10:32 PM
Dear Colleagues,

I am interested in normalizing my surface EMG results (Quadriceps,
both static and
dynamic trials). I have been told
a) to divide the RMS by the MVIC (peak MVIC or mean?- not clear),
b) to divide the entire signal by the MVIC (peak MVIC or mean?-not
clear) and then take the RMS
c) to divide the entire signal by the entire MVIC signal and then
take the RMS, etc.

Unfortunately, I cannot retrieve in detail any specific method about this issue
from the literature. Does anyone know the best method to do this, or
advice me about a paper dealing with this in detail (explaining for
example pros-cons etc)?

Thank You very much!

PS: MVIC=Maximal Voluntary Isometric Contraction
