WARNINGS (continued)
Stimulation should not be applied over the anterior neck or mouth.
•
Severe spasm of the laryngeal and pharyngeal muscles may occur
and the contractions may be strong enough to close the airway or
cause difficulty in breathing.
Stimulation should not be applied transthoracically in that the
•
introduction of electrical current into the heart may cause cardiac
arrhythmia.
Stimulation should not be applied over swollen, infected, and
•
inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis,
varicose veins, etc.
Stimulation should not be applied over, or in proximity to, cancerous
•
lesions.
Output current density is related to electrode size. Improper
•
application may result in patient injury. If any question arises as to

DANGERS
Stimulus delivered by the TENS waveforms of this
•
device, in certain configurations, will deliver a charge of
25 microcoulombs (μC) or greater per pulse and may be
sufficient to cause electrocution. Electrical current of this
magnitude must not flow through the thorax because it
may cause a cardiac arrhythmia.
Patients with an implanted neurostimulation device
•
must not be treated with or be in close proximity to
any shortwave diathermy, microwave diathermy,
therapeutic ultrasound diathermy, or laser diathermy
anywhere on their body. Energy from diathermy
(shortwave, microwave, ultrasound, and laser) can be
transferred through the implanted neurostimulation
system, can cause tissue damage, and can result in
severe injury or death. Injury, damage, or death can
occur during diathermy therapy even if the implanted
neurostimulation system is turned “off.”
Handle, clean, and dispose of components and accessories
•
that have come in contact with bodily fluids according
to National, Local and Facility rules, regulations and
procedures.

IFC- Interferential (Traditional 4 Pole)
Interferential Current is a medium frequency waveform. Current is
distributed through two channels (four electrodes). The currents
cross each other in the body at the area requiring treatment.
The two currents interfere with each other at this crossing point,
resulting in a modulation of the intensity (the current intensity
increases and decreases at a regular frequency).

TENS- Symmetrical Biphasic
The Symmetrical Biphasic waveform has a short pulse duration
and is capable of strong stimulation of nerve fibers in the skin
and in muscle. This waveform is often used in portable muscle
stimulation units, and some TENS devices. Because of its short
pulse duration, the patient typically tolerates the current well,
even at relatively high intensities.
