  • EMG Error propagation

    For those of you who use ensemble averages of EMGs of repeated trials of
    the SAME movement, I address the following questions to you. When
    reporting ensemble averages, do you report the standard deviations of the
    trials as well? If so, do you propagate these SDs when these averages are
    used to calculate differences in response amplitudes from DIFFERENT movements.

    Any insights on this will be greatly appreciated.

    thanks,
    Arnel
