2. Align the proximal end of one of the lead bodies against the inside end of
an 8-contact lead groove of the connector (Figure 2a).
3. Check that the lead-body contacts line up with the electrical contacts
inside the lead groove.
Note: The lead bodies fit only one way into the snap-lid connector.
4. Press the lead body gently into the lead groove (Figure 2b). Repeat steps
2-4 for the second lead body.
Note: Connect the lead body with the marker band to the 0-7 lead groove.
The other lead body connects to the 8-15 lead groove.
5. Close the lid until the latch snaps shut in order to seat the lead bodies in
the lead grooves.
Note: Do not force the lid closed; it should close easily. If it does not,
disassemble the components and repeat steps 1-5 in this section.
6. After connecting the cable to the patient's implanted lead, pass the plug
end out of the sterile field.
7. After verifying that the external neurostimulator is turned off, connect the
cable plug to the receptacle of the external neurostimulator.

Warning: Maintain adequate slack in the cable. If there is not
enough slack and the cable is pulled, the implanted components
may be dislodged.
8. Identify optimal stimulation parameters, beginning at a pulse width of 210-
240 µs and a rate of 30 Hz.
Note: Ensure that the patient can provide immediate feedback.
9. Increase the amplitude beginning from 0.0 V while asking the patient
closed-ended questions to identify the perception threshold (the
amplitude at which the patient first perceives paresthesia), the discomfort
threshold (the amplitude at which paresthesia is beyond the patient's
tolerance), and the paresthesia coverage.
Note: If good paresthesia coverage is not attained, change electrode
settings before repositioning the lead to confirm the direction of lead
movement.
10. In the patient's chart, document the lead position that provided
appropriate stimulation coverage (ie, record the settings and patient
responses and include a fluoroscopic image of the final lead position).
11. Disconnect the cable from the lead by opening the snap-lid connector and
gently lifting the lead bodies from the electrical contacts in the lead
grooves. Leave the cable in the sterile field for additional parameter
testing before closing.
#
Caution: Do not pull on the cable. Pulling on the cable may break
a wire or dislodge the lead. A broken wire or dislodged lead may
result in loss of stimulation and may require surgery to replace the
lead.
