patient setup
For the RIGHT temporalis anterior bundle, touch the muscle during the
maximum clenching and find the major axis of the zygomatic process of
the frontal bone; the electrode should be applied along a line parallel to
this axis that runs through a couple of centimeters posterior to the process
and above the temporal process of the zygomatic bone.
Repeat the procedure also with the LEFT temporalis anterior bundle,
trying to maintain a symmetry of positioning.
For the RIGHT masseter, position yourself behind the patient when
possible and touch the muscle during the maximum clenching, finding
its venter.
The electrode should be applied along the line that connects the external
canthus of the eye with the mandibular angle.
Repeat the procedure also with the LEFT masseter, trying to maintain a
symmetry of positioning.
It is recommended to apply in advance the probes on the pre-
gelled through the special clips, in order to avoid exerting pressure
directly on the subject face.
Before proceeding with the acquisition, verify that the chair’s
back is in vertical position. We ask to the subject to stay relaxed
with your legs uncrossed, hands resting on his knees and looking
forward.
