Chapter 1 : INTRODUCTION
EXPLANATION OF EMS
Electrical Muscle Stimulation 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, originally invented
by John Faraday in 1831. Through the square wave pattern it is
able to work directly on muscle motor neurons. The AGF-6X2 Digital
EMS 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 treatment
of muscular injuries and for the re-education of paralyzed muscles,
to prevent atrophy in affected muscles and improving muscle tone
and blood circulation.
HOW EMS WORKS
1. Relaxation of muscle spasms
2. Prevention or retardation of disuse atrophy
3. Increasing local blood circulation
4. Muscle re-education
5. Immediate post-surgical stimulation of calf muscles to prevent
venous thrombosis
6. Maintaining or increasing range of motion
The EMS units send comfortable impulses through the skin that
stimulate the nerves in the treatment area. W hen the muscle
receives this signal it contracts as if the brain has sent the signal
itself. As the signal strength increases, the muscle f lexes as in
physical exercise. Then when the pulse ceases, the muscle relaxes
and the cycle starts over again, (Stimulation, Contraction and
Relaxation.) Powered muscle stimulators should only be used under
medical supervision for adjunctive therapy f or the treatment of
medical diseases and conditions.
IMPORTANT SAFETY INFORMATION!
Read instruction manual before operation. Be sure to comply with
all “CAUTIONS” and “W ARNINGS” in the manual. Failure to follow
instructions can cause harm to user or device.
Chapter 2: CAUTIONS
1. Federal law (USA) restricts this device to sale by or on the
order of a physician
2. Safety of powered muscle stimulators for use during pregnancy
has not been established.
3. Caution should be used for patients with suspected or diagnosed
heart problems.
4. Caution should be used for patients with suspected or diagnosed
epilepsy.
5. Caution should be used in the presence of the following:
a. When there is a tendency to hemorrhage following acute
trauma or fracture;
b. Following recent surgical procedures when muscle
contraction may disrupt the healing process;
c. Over the menstruating or pregnant uterus; and
d. Over areas of the skin which lack normal sensation.
6. Some patients may experience skin irritation or hypersensitivity
due to the electrical stimulation or electrical conductive medium.
The irritation can usually be reduced by using an alternate
conductive medium, or alternate electrode placement.
7. Electrode placement and stimulation settings should be based
on the guidance of the prescribing practitioner.
8. Powered muscle stimulators should be kept out of the reach of
children.
9. Powered muscle stimulators should be used only with the leads
and electrodes recommended for use by the manufacturer.
10.Portable powered muscle stimulators should not be used while
driving, operating machinery, or during any activity in which
involuntary muscle contractions may put the user at undue
risk of injury.

Chapter 3 : WARNINGS
1. The long-term effects of chronic electrical stimulation are
unknown.
2. Stimulation should not be applied over the carotid sinus nerves,
particularly in patients with a known sensitivity to the carotid
sinus reflex.
3. 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 clos e the airway or
cause difficulty in breathing.
4. Stimulation should not be applied transthoracically in that the
introduction of electrical current into the heart may cause cardiac
arrhythmias.
5. Stimulation should not be applied transcerebrally.
6. Stimulation should not be applied over swollen, infected, or
inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis,
varicose veins, etc.
7. Stimulation should not be applied over, or in proximity to,
cancerous lesions.
Chapter 4: CONTRAINDICATION
Powered muscle stimulators should not be used on patients with
cardiac demand pacemakers.
Chapter 5: ADVERSE REACTIONS
Skin irritation and burns beneath the electrodes have been reported
with the use of powered muscle stimulators. If skin irritation occurs,
discontinue use and consult your physician.
Chapter 6: GENERAL DESCRIPTION
The EMS is a battery operated pulse generator
that sends electrical impulses through electrodes to the body and
reaches the underlying nerves or muscle group. T he device is
provided with two controllable output channels, each independent
of each other. An electrode pair can be connected to each output
channel.
The electronics of the EMS create electrical
impulses whose Intensity, Pulse W idth, Puls e Rate, Contraction,
Relaxation and Ramp may be altered with the switches. Press
buttons ar e very easy to us e and the panel c over prevents
accidental changes in the setting.

Chapter 18: APPLICATION OF RE-USABLE SELF
ADHESIVEELECTRODES
Application
1. Clean and dry the skin at the prescribed area thoroughly with
soap and water prior to application of electrodes.
2. Insert the lead wire into the pin connector on the pre-wired
electrodes.
3. Remove the electrodes from the protective liner and apply the
electrodes firmly to the treatment site.
Removal
1. Lift at the edge of electrodes and peel; do not pull on the lead
wires because it may damage the electrodes.
2. Place the electrodes on the liner and remove the lead wire by
twisting and pulling at the same time.
Care and Storage
1. Between uses, store the electrodes in the resealed bag in a
cool dry place.
2. It may be helpful to improve repeated application by spreading a
few drops of cold water over the adhesive and turn the surface
up to air dry. Over Saturation with water will reduce the adhesive
properties.
the initial results are not positive, speak to your physicianabout
alternative stimulation settings and/or electrode placements. Once
an acceptable placement has been ac hieved, mark down the
electrodes sites and the settings, so the patient can easily continue
treatment at home.
Chapter 17: TIPS FOR SKIN CARE
To avoid skin irritation, especially if you have sensitive skin, follow
these suggestions:
1. Wash the area of skin where you will be placing the electrodes,
using mild soap and water before applying electrodes, and after
taking them off. Be sure to rinse soap off thoroughly and dry skin well.
2. Excess hair may be clipped with scissors; do not shave stimulation area.
3. Wipe the area with the skin preparation your physician has
recommended. Let this dry. Apply electrodes as directed.
4. Many skin problems arise from the “pulling stress” from adhesive
patches that are excessively stretched across the skin during
application. To prevent this, apply electrodes from center
outward; avoid stretching over the skin.
5. To minimize “pulling stress”, tape extra lengths of lead wires to
the skin in a loop to prevent tugging on electrodes.
6. When removing electrodes, always remove by pulling in the
directionof hair growth.
7. It may be helpful to rub skin lotion on electrode placement area
when not wearing electrodes.
8. Never apply electrodes over irritated or broken skin.
