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.
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.
INTENDED USE
EMS Unit is applicable to patients diagnosed with wide range of orthopedic and
neurologic deficiencies who demonstrate difficulties during voluntary movements.
This is a prescription device and should be used under continued medical supervision.
And it is intended use as below:
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.
Chapter 2: CONTRAINDICATION
Powered muscle stimulators should not be used on patients with cardiac demand
pacemakers.
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 close 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.
2
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.
8. Remove batteries if the unit is not used for a long period of time.
9.Keep the unit away from sources of high magnetic fields such as TV’s,
microwave ovens and hi-fi speakers, as these may affect the LCD screen.
10. Do not apply stimulation before attaching electrodes on the skin.
11. During stimulation, do not touch the patient and treatment site at a time
12. Do not apply stimulation in the presence of electronic monitoring equipment
(e.g., cardiac monitors, ECG alarms), which may not operate properly when
the electrical stimulation device is in use.
Chapter 4: PRECAUTIONS
1. Safety of powered muscle stimulators for use during pregnancy has not been
established.
2. Caution should be used for patients with suspected or diagnosed heart problems.
3. Caution should be used for patients with suspected or diagnosed epilepsy.
4. 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.
5. 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.
6. Electrode placement and stimulation settings should be based on the guidance
of the prescribing practitioner.
7. Powered muscle stimulators should be kept out of the reach of children.
8. Powered muscle stimulators should be used only with the leads and electrodes
recommended for use by the manufacturer.
9. 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 5: ADVERSE REACTIONS
Skin irritation and burns beneath the electrodes have been reported with the use
of powered muscle stimulators.

Chapter 14: ELECTRODE PLACEMENT
The placement of electrodes can be one of the most important parameters in
achieving success with EMS therapy. Of utmost importance is the willingness of
the clinician to try the various styles of electrode placement to find which method
best fits the needs of the individual patient.
Every patient responds to electrical stimulation differently and their needs may
vary from the conventional settings suggested here. If the initial results are not
positive,feel free to experiment.Once an acceptable placement has been achieved,
mark down the electrode sites and the settings on the patient’s Reference sheet
of this manual so the patient can easily continue treatment at home.
Chapter 15: TIP 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 clinician 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 direction of 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.
For the safety of the user, Please turn the adjuster slowly because
The EMS unit is not running if you turn the adjuster rapidly.
Chapter 16: APPLICATION OF RE-USABLE SELF
ADHESIVE ELECTRODES
Application
1. Clean and dry 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.
Remove
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.
NOTE
1. Do not apply to broken skin.
2. The electrodes should be discarded when they are no longer adhering.
3. The electrodes are intended for single patient use only.
4. If irritation occurs, discontinue use and consult your clinician.
5. Read the instructions for use of self-adhesive electrode before application.

8. Step to Set Parameter
The parameter of a treatment course can be adjusted according to the following
steps. Press “Select” button to select the function you wish to set.
a. Turn on the intensity
After the electrodes are placed firmly on skin and the lead wires are plugged in the
socket of device, turn the on/off control clockwise. The menu will appear on LCD.
Notice the indication of power and function on the LCD.
b. Set Contraction Time
The contraction time controls the time of stimulation. By pressing parameter
controls, the contraction time can be pre-set. The range is adjustable from 1
second to 30 seconds.
c. Set Relaxation Time
The relaxation time determines the time of relaxation. The stimulation ceases at
setting. Relaxation time of both channels is changed by pressing the parameter
controls. The range of it is adjustable from 1 second to 45 seconds.
d. Set Ramp Time
This ramp time controls the time of output current that increases from 0 to the
setting level and from the setting value to 0. When the ramp time is set, each
contraction may be ramped in order that signals come on and come off gradually
and smoothly. The ramp time is adjustable from 1 second to 8 seconds by pressing
the parameter controls.
Note: Gradual “Ramp” time
The stimulator special circuitry is designed so the electrical impulses gradually build
to a peak and then level off. This “ramped” pulse produces a gradual muscle
contraction emulating natural muscle movement. It can also prevent spastic
patients from reacting adversely. The duration and intensity of the electrical pulses
are predetermined by the clinician.
e. Set Pulse Rate
The pulse rate determines how many electrical impulses are applied through the
skin each second. By pressing the parameter controls, the number of current
impulses per second (Hz) for both channels can be continually adjusted.
The pulse rate is adjustable from 1 Hz to 150 Hz.
f. Set pulse Width
The pulse width determines the length of time. Each electrical signal is
applied through the skin, which controls the strength and sensation of the
stimulation.The pulse width is adjustable from 50 to 250 ㎲. Press the buttons
until the desired value is reached.
