Abstract
We measured head position and the surface electromyographic (EMG) activities
from various locations on the back of the neck during time-optimal head
movements to clarify the effects of electrode location on recorded EMG signal.
To precisely record the electrode locations used, we defined the coordinate
system with respect to the seventh cervical vertibrae. Location 2 where the
splenius was directly below the skin shows the classical tri-phasic EMG pattern
and best characterized splenius activity. Our results show that care must be
exercised when interpreting surface EMG evidence in complex muscle/joint
systems.
