    Dear Colleagues,

    I am looking for data regarding the timing of activation and inactivation
    of different limb muscles during human motion (probably from EMG data). I
    am trying to relate these "on and off" (activation and inactivation) time
    points with salient kinematical events of walking like extrema of joint
    positions and angles. Any data associating muscle activation timing and
    kinematics would be very helpful. I'm sure this has been done many years
    back - I just don't know where to find accurate data.

    I initially looked into the book "Human Walking" by Inman et al. They had
    pictorial representation of the limb position and muscle activation but
    they only had a few frames to describe a full walking stride. The ISB
    database had some EMG data with better resolution (20 ms per frame), but
    there is no kinematic data along with it. Also, this database only had
    data on walking, I'm looking to compare different gaits as well.


    Could someone point me to the right place ?

    Thanks,

    Sandhitsu,

    Try these two references:

    Nashner, L.M., Forssberg, H. (1986). Phase-dependent organization of
    postural adjustments associated with arm movements while walking.
    Journal of Neurophysiology, 55(6), 1382-1394.


    Hirschfeld, H. Forssberg, H. (1991). Phase-dependent modulations of
    anticipatory postural activity during human locomotion. Journal
    of Neurophysiology, 66, 12-19.

    These are from my thesis, if I run across any others I will send them to you. Good luck

    Sandhitsu,

    I'm currently involved in a small project looking at EMG ON/OFF timing of
    the calf muscles during gait. My co-investigators (mostly Pat Riley at
    Spaulding Hospital, Boston) have helped to assemble some relevant citations
    in the field. The easiest thing for me to do was to copy the reference
    section of our draft paper and attach it below. Several of the citations
    could be helpful (please ignore the citations that are unrelated and the
    inconsistent format!).

    Hope this is helpful,

    Ted Clancy

    Hi,

    I have only one answer for you. Go on PubMed and look for David Winter's
    work back in the 80's. Do a search from about 1976 and you'll find many
    articles on what you're looking for.

    Cheers!

    Dear Sandhitsu,

    I spent a long time in determination of the onset and offset of EMG.
    The EMD at the beginning of a movement - I called it the electromechanical
    activation delay (EMAD) - is about only just 20 ms in an isometric explosiv
    contraction.
    The EMD at the end of a movement - I called it the electromechanical
    relaxation delay (EMRD) - is about 60 to 100 ms but with minor accuracy
    because of methodological problems.
    A part of the result including informations you are looking for are
    published in english:

    motion analysis - methodological problems and limitations. In: Hong, Y.

    Sandhitsu,

    This may be more of a hindrance than help.

    Since you are familiar with Inman's book, 'Human Walking", look on page 96,
    figure 5.10, from Lombard. If this holds in humans, (I assume we have
    evolved as far), two joint muscles may function isometrically and
    isotonically. Once the tone is set, EMGs are constant and, essentially,
    electrically silent. It would be like setting the tension in a wire wheel
    spoke and then keep rollin', rollin', rollin'. The spoke tension is
    constant. Muscles would only contract once, then hold the tone. EMGs would
    be worthless.

    Dear Mr. Das,

    Unfortunately, I don't have the data that you are looking for. However,
    I wanted to introduce myself. Please review my attached letter and let
    me know what you think.

    I am also curious to know what kind of equipment you are using for your
    studies??

    Thanks and have a good day!
