Intraoperative Stimulation
Testing
Note: The following steps are for procedural
reference only. Please refer to the
Bionic Navigator Software Guide for
detailed stimulation testing procedures
and guidelines.
1. If using a splitter:
• Visually check splitter to leads
connection
• Check impedance
Note: If using the 2x4 Splitter, make
note of splitter configuration in the
Bionic Navigator™ software per
Splitter Programming Guide.
2. After linking the Clinician Programmer to
the Trial Stimulator, check impedances
to verify that components are properly
connected. Lead impedance is measured
and displayed for each of the IPG's
16 electrode contacts. Impedances
over 4500 Ohms are considered to be
resultant from open or unconnected wires,
displayed with an X.
3. Using test stimulation, enlist patient
feedback to verify lead placement and
pain coverage.
Note: If lead repositioning is necessary, turn
stimulation off before proceeding.
4. Reposition leads as necessary. If using
a splitter, gently pull on lead attached to
splitter to reposition caudad or disconnect
splitter from leads, re-insert stylet, and
advance leads to reposition cephalad.
CAUTION: Do not force stylet into lead.

5. Steer lead to new position.
6. Remove stylet, wipe proximal ends of
leads and reconnect splitter.
7. Check impedances.
8. Repeat steps 1-3 if lead has been
repositioned.
9. When the desired paresthesia is
achieved:
a) Turn the Trial Stimulator off.
b) Unlock each OR cable connector and
disconnect from the lead(s).
c) For percutaneous lead(s) - slowly
withdraw the stylet(s).
10. Record the lead position by capturing a
fluoroscopic image to be sure the leads
have not moved. Retest if necessary.
11. If using a splitter, disconnect splitter from
leads. Insert the hex wrench and turn the
set screw counter clockwise to loosen.
Note: • The set screw should only be
loosened to an amount sufficient to
insert a lead.
• Do not excessively loosen the set
screw. This may cause the set screw
to dislodge, rendering the splitter
unusable.
