MANAGE YOUR PAIN
WHEN ACTIVE OR AT REST
MEDICAL CONTEXT
USING THE TRANSCUTANEOUS ELECTRICAL NERVE STIMULATOR (TENS)
TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION IS SCIENTIFICALLY PROVEN AND
PRESCRIBED BYMEDICAL PROFESSIONALS
Transcutaneous electrical nerve stimulation -TENS- depolarizes peripheral nerve bres and is transmitted through electrodes
placed on the body to reinforce the effectiveness of the natural pain control mechanisms.
TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION APPLIED AT THE SENSORY LEVEL
A tingling sensation is induced to trigger a natural analgesic reaction.
COMPLEMENT OR ALTERNATIVE TO TAKING MEDICATION
Neurostimulation is used for acute postoperative and post-traumatic pain and muscle relaxation and for treating many
othertypes of pain that are not relieved by medication.
ACCESSIBLE TO ALL
The ability to choose the most appropriate TENS program for your type of pain makes TENS one of the most effective
non-surgical and non-drug therapy solutions. Transcutaneous electrical nerve stimulation -TENS- is much more than a simple
compliment to any traditional treatment. TENSallows you to move more and live better.

1.3 SAFETY MEASURES
INDICATIONS, CONTRAINDICATIONS, PRECAUTIONS, CAUTION
Transcutaneous electrical nerve stimulation meets each user’s specic needs. This non-aggressive and drug-free technique is recognized for its lack
of side effects under normal use conditions, moderate cost, the small size of the TENS device, and its ease of use. The -TENS- is compact and can
be slipped into a pocket, making it easier to carry out daily activities.

CONTRAINDICATIONS
•Cancer - absolute contraindication: wait until the end of the remission period for metastasis or circulatory cancer (leukemia).
- local contraindication: wait until the end of the remission period for other types of cancer, under interdisciplinary supervision.
• Cardiac pacemaker: absolute or local contraindication, to be used under interdisciplinary supervision with permission from the attending cardiologist.
LOCAL CONTRAINDICATIONS
DO NOT APPLY TO THESE REGIONS
•Transcranial application: the risks of applying the electrodes in a transcranial application are unknown.
•Anterior neck region, carotid sinus (throat): risk of stimulating the vagus or phrenic nerves, pharyngeal muscles, or carotid sinuses.
•Eyes: the risks of treating this part of the body are unknown.
•All types of infections: risk of spreading the infection.
•Skin impairment: psoriasis, eczema, etc.. Caution in the vicinity of open wounds or healing scars.
•Undiagnosed persistent pain.
LOCAL CONTRAINDICATIONS
USE UNDER MEDICAL OR INTERDISCIPLINARY SUPERVISION
•Transthoracic and anterior application of the cardiac region.
•Electronic implant: risk of interference with the implant’s function.
•Heart disease: risk that the heart will have difculty compensating for the high metabolic demand.
•Pregnancy: abdominal and lumbar region during pregnancy. The -TENS- may be used in the lumbar region during childbirth.
•Skin sensory disorder, loss of sensitivity: risk that the patient does not adequately feel the current, which increases
the risk of skin burns or irritation.
•Genital organs: requires training.
•DVT/active phlebitis/embolism: risk of thrombus displacement in the bloodstream.
•Hemorrhage: risk of increasing bleeding.
•Epilepsy: local contraindication to the head and neck (cervical region). Precaution for the trunk and limbs.
Electrical stimulation could trigger an epileptic seizure.
• Tuberculosis: electrical stimulation in this area may spread the infection during the active phase.
•Pacemaker: absolute or local contraindication, to be used under interdisciplinary supervision
with authorization from the attending cardiologist.

page
PRECAUTIONS
• Circulatory dysfonction : stimulation increases the metabolic demand, which may exceed the oxygen supply, thus increasing pain.
This may even lead to tissue ischemia or necrosis.
• Skin disease: resistance is decreased, increasing the risk of burns.
• Active epiphyseal plate: risk of impairing bone growth.
• Chest, heart, and lower abdominal area: risk of affecting normal heart function.
• Communication disorder: risk of injury, misunderstanding of use; under interdisciplinary supervision.
CAUTION
• Children: keep out of the reach of children.
• Driving a vehicle: never handle the -TENS- device or move the electrodes while driving.
• Risk of skin damage when using carbon electrodes: always use electrode gel.
WARNING
• Do not adjust or perform maintenance on your Electro-Medic -TENS- device while it is in operation.
• Near other equipment. Do not use the device when it is placed near to or above other equipment. If it is necessary to use it in such a
conguration, make sure that ALL DEVICES ARE working properly under these conditions.
• Do not use the device at the same time as monitoring equipment (e.g. ECG equipment) operating with electrodes. The signals of the device could
interfere with those of the monitoring device.

The electrodes used with this device must never be smaller than
2.54cm in diameter. We caution you that the smaller the electrodes,
the greater the stimulation intensity in the area where the electrodes
are placed, which increases the risk of skin irritation in that area. The
risk of skin irritation also occurs when self-adhesive electrodes do not
stick properly to the entire surface due to a lack of adhesion. Replacing
the self-adhesive electrodes after a maximum of 15 to 20uses ensures
superior device performance. Use carbon electrodes with electrode
gel to ensure a proper and effective current ow. Please refer to the
additional instructions provided on the electrode packaging.

washed with water, cleaned, and

adhesion and optimal performance.
To optimize your results, we recommend that you

DIFFERENT POSSIBLE MODULATION MODES
CCONVENTIONAL STIMULATION
In the conventional stimulation mode, the impulses are continuous with a xed rate and width.
BBURST
In Burst mode, there are two impulse trains per second (2 Hz).
MR MODULATED PULSE FREQUENCY
The frequency decreases from 160 Hz to 65 Hz in 9 equal stages, then returns to the selected value in 9 stages.
The total cycle time is 6 seconds.
MW MODULATED PULSE DURATION
The impulse duration decreases from 150 Us to 70 Us in 9 equal stages, then returns to the selected value in 9 stages.
The total cycle time is 3 seconds.
CM COMBINED MODULATION STIMULATION
Combined modulation consists of alternating the impulse width (MW) and frequency (MR) so that one parameter always decreases while the other
increases and vice versa.
MXF MIXED IMPULSE FREQUENCY
The mixed frequency alternates between high and low frequency every 5 seconds, thus integrating high- and low-frequency stimulation.
Inthismode, the screen displays •The Fand the up arrow during high frequency
•The Fand the down arrow during low frequency
ALT ALTERNATING
When a massage and pain relief effect is desired, place the electrodes as for high-frequency stimulation. Although modulated high-frequency stimu-
lation is obtained, the channels are activated alternately, producing a massage effect. Always use 2 channels and 4 electrodes with this program.
The program is the same for both channels.
