Issues Delivering Stimulation
Issue
Presentation
Resolution
Stimulation is not being
delivered during lead
implant procedure
No motor or sensory responses are
observed during test stimulation
•
If there are no blue bars in the stimulation bar when
stimulation is on, there is an issue with the connection.
•
Check the impedance using the CP.
•
Confirm the device cables are connected correctly.
Replace the cables if impedance is bad when the
cables are correctly connected.
•
If stimulation appears to be on, adjust the needle or lead
and stimulation amplitude until a motor or sensory
response is observed
Stimulation is not being
delivered during
Neurostimulator
programming
The patient does not report any
sensation of stimulation or
symptom relief
•
Check the lead impedance on the Patient Device screen. If
there is an impedance issue with the active electrode(s),
reprogram the device to only use electrodes with
acceptable impedance.
•
If there is still an issue, confirm that the CP is
communicating with the correct Neurostimulator. Try
disconnecting and reconnecting the CP to the
Neurostimulator.
Lack of or change in
stimulation sensation
Patients may report they are not
feeling stimulation or the sensation
(intensity or location) of
stimulation has changed
If the stimulation sensation is associated with a lack of symptom
benefit, the following steps can be taken to assess and
troubleshoot the patient’s therapy:
1.
Check if stimulation is turned on.
a.
This check can be accomplished by connecting
the Clinician Programmer or patient Remote
Control to the stimulator.
2.
Check the electrode impedances to determine if there
is a connection issue (e.g., lead fracture or short).
