normalizing EMG signals, how to process MVC data?
Posted: Sun Mar 08, 2015 7:08 am
Hello all,
I am trying to normalize electromyography signals taken during an exercise in which I also obtained kinematic data. I have used the kinematic data to get activations from CMC and want to accurately compare them to the obtained EMG signals. I filtered the EMG signals by putting them through a high pass and then low pass filter. I then rectified them and put them through another low pass filter. I know that to normalize the signals I need to do a maximum voluntary contraction and use the maximum value obtained. My question is how do I filter the MVC signals? Do I filter them in the exact same way as I filtered the original signals obtained during the experiment?
Any help would be appreciated.
Thanks,
Brandon
