1. SAFETY INFORMATON
1.1 General
MT9000 Combo is a portable electrotherapy device featuring four therapeutic modes:
Transcutaneous Electrical Nerve Stimulation (TENS),Electrical Muscle
Stimulation(EMS),lnterferential(lF), and Microcurrent(MIC) 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.
1.2 Medical background
EXPLANATION OF PAIN
Pain is a warning system and the body’s method of telling us that something is wrong.
Pain is important; without it abnormal conditions may go undetected, causing damage
or injury to vital parts of our bodies. Even though pain is a necessary warning signal of
trauma or malfunction in the body, nature may have gone too far in its design.
Aside from its value in diagnosis, long -lasting persistent pain serves no useful purpose.
Pain does not begin until coded message travels to the brain where it is decoded,
analyzed, and then reacted to. The pain message travels from the injured area along
the small nerves leading to the spinal cord, Here the message is switched to different
nerves that travel up the spinal cord to the brain. The pain message is then interpreted,
referred back and the pain is felt.
EXPLANATION OF TENS
Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive, drug free 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 must patients it is
effective in reducing or eliminating the pain, allowing for a return to normal activity.

EXPLANATION OF EMS
Electrical Muscle Stimulation 1EMS) is an 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-shaped).Through the square wave pattern it is able to work
directly on muscle motor neurons. This device has low frequency and this in conjunction
with the square wave pattern alIows direct work on muscle groupings. This is being
widely used in hospitals and sports clinics for the treatment of muscular injuries and for
the re-education of paralyzed muscles, to prevent atrophy in affected muscles and
improvinq 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 4000 Hz, and the other can beheld constant or varied
over a range of 4001 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 by
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, posttraumatic 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 tissues healing rate. The
immediate response to the correct microcurrent frequency suggests that other
mechanisms are involved as well. The exact effects or changes in the tissue are
unmistakable: scars will often suddenly soften, trigger points often became less painful
within minutes when the “correct” frequency is applied. In many situations the changes
seem to be long lasting and in many cases permanent.

established or unless a pain syndrome has been diagnosed.
2) This device should not be used when cancerous lesions are present in the treatment
area.
3) Stimulation should not be applied over swollen, infected, inflamed areas or skin
eruptions (e.g. phlebitis, thrombophlebitis, varicose veins, etc.).
7
4) Electrodes must not be applied to sites that might cause current/stimulation to flow
through the carotid sinus region (anterior neck) or transcerebrally (through the head).
5) Do not use this device if the patient has a demand-type cardiac pacemaker or any
imnplanted defibrillator,
6) This device should not be used over poorly innervated areas.
7) Epilepsy
8) Serious arterial circulatory problems in the lower limbs

10) Do not use this device if you have heart disease without consulting your physician.
1.5. Warnings,Cautions, and Adverse Reactions
WARNINGS:
1) This device should he 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) 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 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.
9) Stimulation should not be applied transthoracically . The introduction of electrical
current into the heart may cause cardiac arrhythmias.
8
10) Stimulation should not take place while the user is connected to high- frequency
surgical equipment. It may cause burn injuries in the skin under the electrodes, as well
as problems with the stimulator.
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 may 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 areas of the skin which lack normal sensation
17) Apply the electrodes to clean, dry, and unbroken skin only.
I8) Keep electrodes separate during treatment, electrodes in contact with each other
could result in improper stimulation or skin inflammation.
