Table 8. Troubleshoong during postoperave programming
Problem Possible Cause Possible Soluon
IPG baery is low and smulaon
shut o.
Recharge the IPG.
Paent has inadvertently changed the
programming.
Reprogram the system;
review operaon and usage
with the paent.
Implant is damaged. Contact Technical Support.
Less-Than-Opmal Smulaon
Smulaon eld does not overlap
the pain paern.
Acve electrodes are not posioned
over the target.
Set amplitude to zero and
program dierent
electrodes.
Lead has migrated. Evaluate with uoroscopy.
Aempt to reprogram the
electrode selecons prior to
surgical intervenon.
Pain paern has changed. Reposion smulaon
coverage by reprogramming
electrode selecon or
surgically reposioning the
lead.
Smulaon does not provide
adequate pain relief but overlaps
the pain paern.
Smulaon program is ineecve. Set amplitude to zero and
select new smulaon
values.
MaxTol seng is too low. Test the seng and
reprogram if necessary.
Paent adapted to smulaon. Consider changing from
connuous to MulSm™
smulaon mode.
Intermient Smulaon
Amplitude sengs remain constant
but smulaon is intermient.
Paent is sensive to changes in body
posion that aect smulaon.
Adjust amplitude; reprogram
the system if necessary.
Paent has inadvertently changed the
programming.
Reprogram the system;
review operaon and usage
with the paent.
Implantable system is damaged or
malfunconing.
Contact Technical Support.
Uncomfortable Smulaon
Smulaon is uncomfortable. Amplitude and/or pulse width sengs
are too high.
Adjust sengs to a
comfortable level, avoiding
abrupt changes.
NOTE: Amplitude should
be decreased as pulse
width is increased.
