Glossary
Lead – Surgical wire: takes electrical signals from the neurostimulator to the stimulation area
Stimulation – Small electrical pulses: produces a tingling sensation and replaces pain signals
Stimulator – Device that makes electrical pulses that will stimulate the nerves in your spine: can
refer to either the Trial Neurostimulator or Implantable Neurostimulator
Trial Neurostimulator (TNS) – External Stimulator that clips onto your belt: attaches to the
connector cable, which is connected to the leads that are implanted in the area near your spine
Implantable Neurostimulator (INS) – Stimulator implanted in your back or abdomen: attaches to
leads implanted in the area near your spine
Connector Cable – Cable that connects the leads to your Trial Neurostimulator
Programmer – Portable, hand-held device: allows you to adjust your stimulation settings
Clinical Programmer – Portable, hand-held device: allows the physician to program your
Stimulator.
Computer Tomography (CT) Imaging – Computerized X-ray imaging: produces electronic images
of tissues and organs
Diathermy – High energy heat: used to cut or cauterize during surgery or a type of therapy
Electromagnetic Interference (EMI) – Electrical signals that interfere with the device function
Magnetic Resonance Imaging (MRI) – Medical imaging: produces electronic images of tissues and
organs
Paresthesia – Tingling sensation felt during therapy delivery: produced by spinal cord stimulation
Precaution – Situation that could cause uncomfortable stimulation and possible damage to the
Stimulator or Programmer
Program – Instructions or changes to stimulation settings that are put into the Programmer and
transmitted to the Stimulator
Stimulation Level – Amount of stimulation: can be increased or decreased within a range set up
by your doctor
Warning – Potentially serious hazard that could cause injury or death
