in order to avoid electrical shock. Remove
the batteries from the device if you do not
intend to use it for a prolonged period of
time (more than 3 months). Extended stor-
age of the batteries in the device might
lead to batteries and device damage.
• Cable. The cable is best preserved if left
attached to the stimulator between ses-
sions. Do not jerk the cable or connection.
• Heat and Cold products. The use of heat or
cold producing devices (e.g. electric heat-
ing blankets, heating pads or ice packs)
may impair performance of the electrode
or alter the patient’s circulation/sensitivity
and increase the risk of injury to the pa-
tient.
• Pulled muscles. Do not apply electrodes
over pulled muscles. Using the stimulator
on a previously extended muscle might
further pull such muscle. The higher the
stimulation intensity, the higher the risk to
further overextends such muscle.
• Additional Precautions for TENS
– TENS is not effective for pain of central
origin, including headache.
– TENS is not a substitute for pain medi-
cations and other pain management
therapies.
– TENS devices have no curative value.
– TENS is a symptomatic treatment and,
as such, suppresses the sensation of
pain that would otherwise serve as a
protective mechanism.
• Effectiveness of TENS is highly dependent
upon patient selection by a practitioner
qualified in the management of pain pa-
tients.
12.4. Dangers
• Electrodes. Any Electrode with a minimum
active area of 16 cm² may be used with this
device.Use of an electrode with an area
less than 16 cm² can cause burns when the
unit is used at higher intensities. Consult
your clinician prior to using any electrode
less than 16 cm².
12.5. Adverse reactions
• Patients may experience skin irritation and
burns beneath the stimulation electrodes
applied to the skin.
• Patients may experience headache and
other painful sensations during or follow-
ing the application of electrical stimulation
near the eyes and to the head and face.
• Patients should stop using the device and
should consult with their physicians if they
experience adverse reactions from the de-
vice.
• Precaution: Do not disconnect any stimu-
lation cables during a session while the
stimulator is switched on. Switch the stim-
ulator off first. Always turn off the stimula-
tor before moving or removing any elec-
trodes during a session.
• Precaution: Do not use electrodes with an
active area less than 16 cm2, as there will
be a risk of suffering a burn injury. Caution
should always be exercised with current
densities more than 2mA/cm2.
