Placing the Trigno Sensor on the Skin
Trigno Quattro, Duo and Mini Sensors consist of a main sensor body and four,
two or one cabled detection head(s) respectively. The sensor heads should be
placed near the centroid of the muscle to detect the maximum amount of EMG
activity. The sensor body should be affixed in a convenient nearby location to
provide a detection reference point. The sensor body and sensor head are
easily attached to the skin using the Delsys Adhesive Sensor Interfaces. The
sensor arrow on the top side should be oriented parallel to the direction of the
muscle fibers.
Figure 6. The EMG sensor head must be positioned overtop of the muscle of interest. The
reference contacts can be positioned in a convenient nearby location.
