Define Thresholds
When the tined lead is placed through the introducer sheath,
the CP provides test stimulation to help determine if the lead
electrodes are near the sacral nerve. This section explains how
the CP is used to test and record the responses and response
thresholds for stimulation with each electrode of the tined lead.
Upon entering the Define Thresholds screen, the most proximal
electrode (E3) is selected by default. A different electrode can
be selected by pressing that electrode on the CP screen. A gray
box is visible around each electrode until stimulation is delivered
with the selected electrode ( 1 ). The box changes color
depending on the stimulation amplitude and the motor and
sensory responses evoked. When stimulation is at the minimum
amplitude that evokes the desired physiological response (motor
and/or sensory), the color around the electrode indicates the
quality of that electrode:
Green ‐> Good placement based on relatively low stimulation
•
amplitude and desired responses.
Yellow -> Acceptable placement based on moderate
•
stimulation amplitude and desired responses.
Red -> Undesired placement based on high stimulation
•
amplitude and/or an undesirable sensory response.
The threshold value of the selected electrode is updated each
time a new test stimulation occurs.
