1. Safety information
1.1 General
M T 8 0 0 0 E l e c t r i c a l S t i m u l a t o r i s a p o r t a b l e
electrotherapy device featuring four therapeutic
m o d e s : Tr a n s c u t a n e o u s E l e c t r i c a l N e r v e
S t i m u l a t o r , E l e c t r i c a l M u s c l e S t i m u l a t i o n
Interferential, and Microcurrent,which are used for
pain relief and electrical muscle stimulation. The
stimulator sends gentle electrical current to
underlying nerves and muscle group via electrodes
applied on the skin. The parameters of device are
controlled by the press buttons. Its intensity level is
adjustable according to the needs of patients.
EXPLANATION OF TENS
Transcutaneous Electrical Nerve Stimulation (TENS)
is a non-invasive, drugfree method of controlling
pain. TENS uses tiny electrical impulses sent through
the skin to nerves to modify your pain perception.
TENS does not cure any physiological problem; it
only helps control the pain. TENS does not work for
everyone; however, in most patients it is effective in
reducing or eliminating the pain, allowing for a return
to normal activity.
EXPLANATION OF EMS
E l e c t r i c a l M u s c l e S t i m u l a t i o n ( E M S ) i s a n
internationally accepted and proven way of treating
muscular injuries. It works by sending electronic
pulses to the muscle needing treatment; this causes

the muscle to exercise passively. It is a product
derived from the square waveform (ladder-sha
ped). Through the square wave pattern it is able to
work dire ctly on muscle motor neurons. This device
has low frequency and this in conjunction with the
square wave pattern allows direct work on muscle
groupings. This is being widely used in hospitals and
sports clinics for the reatment of muscular injuries
and for the re-education of paralyzed muscles, to
prevent atrophy in affected muscles and improving
muscle tone and blood circulation.
EXPLANATION OF IF
Interferential Stimulation (IF) is an anti-inflammatory
based treatment modality. Interferential stimulation is
characterized by two alternating-current sine waves
or square waves of differing frequencies that “work”
together to produce an interferential current that is
also known as a beat pulse or alternating modulation
frequency. One of the two currents is usually held at
4,000 Hz, and the other can be held constant or
varied over a range of 4,001 to 4,100 Hz. Because of
the frequency, the interferential wave meets low
impedance when crossing the skin to enter deep into
soft tissues. The interferential currents reportedly
can stimulate sensory, motor, and pain fibers. These
large impulse fibers interfere with the transmission of
pain messages at the spinal cord level. This deep
tissue penetration stimulates parasympathetic nerve
fibers for increased blood flow and edema reduction.
It utilizes the low electric-current to stimulate muscle
nerves to achieve the symptomatic relief of chronic
intractable pain, post-traumatic pain, and post-
surgical pain.

EXPLANATION OF MICROCURRENT
Microcurrent stimulation is a type of therapy in which
very low current is sent into the cells of the body.
Microcurrent is a very faint current that is so small it is
measured in millionths of an amp (Microamps).
Human cells generate a current that is in the
microamp range which is why you can't feel it-the
current is so low it doesn't stimulate the sensory
nerves.
Microcurrent is a physiological electric modality that
increases ATP (energy) production in the cells of your
body. This dramatically increases the tissue's healing
rate. The immediate response to the correct
m i c r o c u r r e n t f r e q u e n c y s u g g e s t s t h a t o t h e r
mechanisms are involved as well. The exact effects
or changes in the tissue are unmistakable; scars will
often suddenly soften; trigger points often become
less painful within minutes when the “correct”
frequency is applied. In many situations the changes
seen seem to be long lasting and in many cases
permanent.
1.3 Indication for use
MT8000 electrical stimulator may be used for
the following conditions:
1) Symptomatic relief of chronic intractable pain;
Post traumatic pain; post surgical pain.
2) Relaxation of muscle spasm.
3) Increase of blood flow circulation
4) Prevention or retardation of disuse atrophy
5) Muscle re-education
6) Maintaining or increasing range of motion.
7) Immediate post-surgical stimulation of calf
muscles to prevent venous thrombosis

1.5 Warnings, Cautions and Adverse Reactions
WARNINGS:
1) This device should be used only under the
continued supervision of a licensed physician.
2) The long-term effects of chronic electrical
stimulation are unknown. Electrical stimulation
devices do not have any curative value .
3) TENS is a symptomatic treatment and, as such,
suppresses the sensation of pain, which would
otherwise serve as a protective mechanism.
4) Safety has not been established for the use of
therapeutic electrical stimulation during
pregnancy. Do not use during pregnancy unless
directed by your physician.
5) Electrical stimulation is not effective for pain of
central origin.
6) Electronic monitoring equipment (such as ECG
monitors and ECG alarms) may not operate
properly when electrical stimulation is in use.
7) Stimulation should not be applied over the
carotid sinus nerves, particularly in patients with a
known sensitivity to the carotid sinus reflex.
8) Stimulation should not be applied over the neckor
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.
9) Stimulation should not be applied transthoracically
in that the introduction of electrical current into the
heart may cause cardiac arrhythmias.
10) Stimulation should not take place while the user is
connected to high-frequency surgical equipment,
it may cause burn injuries on the skin under the
electrodes, as well as problems with the stimulator.
8

11) Do not use the stimulator in the vicinity of
shortwave or microwave therapy equipment, since
this may affect the output power of the stimulator.
12) Never use in environments with high humidity such
as in the bathroom or when having a bath or shower.
13) Caution should be used in applying electrical
stimulation to patients suspected of having heart
disease. Further clinical data is needed to show
there are no adverse results.
14) Never use near the heart. Stimulation electrodes
should never be placed anywhere on the front of
the thorax (marked by ribs and breastbone), but
above all not on the two large pectoral muscles.
Here it can increase the risk of ventricular
fibrillation and lead to cardiac arrest.
15) Electrodes should not be placed over the eyes, in
the mouth, near the genitals or internally.
16) Never use on the areas of the skin which lack
normal sensation
17) Apply the electrodes to clean, dry, and unbroken
skin only.
18) Keep electrodes separate during treatment,
electrodes in contact with other could result in
improper stimulation or skin burns.
19) Keep the stimulator out of reach of children.
20) Consult your doctor if you are in any doubt
whatsoever.
