Working with the Snap Lead Sensors

As with all EMG sensor technolgoy, the Trigno Snap Lead sensors
must be propoerly position above the muscle to to obtain a qualtiy
EMG signal. The snap electrodes must be placed to parallael to the
muscle fiber direction for maximmal signal detection. Rotational
skew from this optimal orientation will diminish signal amplitude

which must be placed parallel to the muscle fiber direction in
order to properly detect an EMG Signal.
and increase the potential for signal crosstalk.
The sensor body and its 4 silver contacts must be well-affixed to the
skin to provide a quality signal reference point for the Snap Lead
EMG contacts. Use the Delsys SC-F03 four-slot adhesive skin inter-
face to adhere the sensor to the skin. These interfaces are manufac-
tured from medical grade adhesive approved for dermatological ap-
