Dear Subscribers to Biomech mailing,
As an occupational ergonomist there is no specific forum in which I can
address concerns or request specific interest. I therefore turn to you
as readers of the Biomech mailing, hoping that this topic is of interest
to you and requesting any feedback.
I am embarking upon a very exciting research project to study how the
human musculoskeletal system reacts to and / or absorbs energy from a
random impact. In this first, of what I hope will become a series of
such studies (given funding and interest) we shall be studing cervical
injury incidence under controlled climbing conditions.
For this study we are utilizing Virtual Instrumentation technology for
simulataneous high capacity data acquisition on 8 channels. EMG = 1
channel (neck extensor muscles), Electrogoniometry = 2 channels (flexion
/ extension and lateral motion of the cervical spine) and Acclerometry =
5 channels (tri-axial at C4-C5, uni-axial at L5-S1 and uni-axial at point
of impact - foot).
I have exhausted conventional means for literature search and was hoping
that any readers might be aware of similar research. Ideally, I would be
interested in biomechanics damage load limits for 'jerk' data - rate of
change of acceleration with respect to time.
If anybody can help me in my quest I would be most grateful.
