View Full Version : Indices of co-contraction using EMG

I have been asked to assist a colleague in quantifying the degree of
agonist/antagonist co-contraction during walking gait using surface EMG.
In a quick review of the relevant literature, I have encountered a number
of different techniques for quantifying such indices of co-contraction. I
have two questions for members who may have greater experience in such
matters:

1) Which indices have been found to be most useful and/or most meaningful?
Please include references to the published literature if available.

2) Since any index of co-contraction will involve EMG signals from at least
two muscles, does normalization of the EMG magnitude present a special
problem? If so, which normalization techniques have been found to be most
effective in minimizing this problem?

As always, I will post a summary of the replies. Thanks in advance

Peter
