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 for the treatment of medical diseases and
conditions.
Chapter 2 : CAUTIONS
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 tendencyto hemorrhage followingacute trauma
or fracture;
b. Following recent surgical procedures when muscle contraction
may dis rupt 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 elec trodes recommended for use by the manufacturer.
Chapter 1 : INTRODUCTION
EXPLANATION OF EMS
Electrical MuscleStimulation is an internationallyaccepted andproven
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. 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 thetreatment area. When themuscle receives
this signal it contracts as if the brain has sent the signal itself. As the
signal strength increases, the muscle flexes as in physical exercise.

Chapter 5: ADVERSE REACTIONS
Skin irritation and burns beneath the electrodes have been reported
with the use of powered muscle stimulators.
Chapter 6 : GENERAL DESCRIPTION
The EMS 5.0 is a battery operated pulse generator that sends
electrical impulses through electrodes to the body and reaches the
underlying nerves or muscle group. The 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 5.0 create electrical impulses whose
Intensity, Pulse Width, Pulse Rate, Contraction, Relaxation and Ramp
may be altered with the switches. Dial controls are very easy to use
and the slide cover prevents accidental changes in the setting.
Chapter 7 : CONSTRUCTION
9. Portable powered muscle stimulators should not be used while
driving, operating machinery, or during any activity in which
involuntary muscle con tractions 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,
particuarly 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.
6. Stimulation should notbeapplied overswollen, 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.

CAUTION
Do not insert the plug of lead wire into the AC power source.
Chapter 13: LEAD WIRE MAINTENANCE
Clean the wires by wiping with a damp cloth. Coating them lightly
with talcum powder will reduce tangling and prolong life.
Chapter 14 : ELECTRODE OPTIONS
You should use the same size and type of electrodes that was
supplied with your EMS device, unless your clinician instructs you to
use a different electrode. Follow application procedures outlined in
electrode packing, to maintain stimulation and prevent skin irritation.
Usethe legally marketed EMS electrode is recommended. The device
is completed with standard carbon film adhesive electrodes in size
4x4cm.
Chapter 15 : 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 electrodes

Chapter 12 : ATTACHMENT OF ELECTRODE LEAD
WIRES
The wires provided with the system insert into the jack sockets
located on top of the device. Holding the insulated portion of the
connector, push the plug end of the wire into one of the jacks (see
drawing); one or two sets of wires may be used.
Afterconnecting the wires to the stimulator, attach each wire to an
electrode. Use care when you plug and unplug the wires. Jerking
the wire instead of holding the insulated connector body may cause
wire breakage.

Chapter 17APPLICATION 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 n 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 be cause 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.
sites and thesettings on the patient’sReferencesheet of this manual,
so the patient can easily continue treatment at home.
Chapter 16 : 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 maybe clipped with scissors; donot 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 prvent 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.

3. On/Off Switch and Intensity Controls:
If both controllers are in the off-position (white markings on the
housing), the device is switched off.
By turning the controls clockwise, the appropriate channel is
switched on and the impulse display led will illuminate and begin
to pulse according to the frequency set.
The current strength of the impulses transmitted to the electrodes
in creases the further the controller is turned clockwise.
To reduce the current strength an/or switch the device off, turn
the controller counter clockwise or turn counter clockwise until it
stops, respectively.
4. Lead Connector
Connection of the electrodes is made with two-lead connector.
The device must be switched off before connecting the cables.
Both intensity controls must be at the Off position. Electrodes
must be pressed firmly on the skin.
Important
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 physician.
5. Read the instruction for use of self-adhesive electrodes before
application.
Chapter 18 : ADJUSTING THE CONTROLS
1. Panel Cover:
A slide-on panel cover covers the controls for Contraction Time,
Relaxation Time, Ramp Time, Pulse Width, and Pulse Rate. Your
medical profes sional may wish to set these controllers for you
and request that you leave the cover in place.
2. Display Led
Each of these leds illuminates whenever
the electronics of the device create a
current impulse at contraction time and
does not illuminate when the stimulation
is ceased at relaxation time. Due to the
capacity of the human eye, the
illumination of the lamp can only be
recognized up to a frequency of
approximately 30 Hz. At higher
frequencies, the lamp will appear to be
constantly illuminated.

8. Ramp Time Control
This dialcontrols the time intensity of current output that increases
from 0 to the setting level. When the ramp time is set, each
contraction may be ramped in order that signals come on
gradually and smoothly. There are 3 choices of ramp time - 1,3,5
seconds.
9. Check/Replace the Battery:
Overtime, inorderto ensure the functional safetyof EMS, changing
the batteries is necessary.
1. Make sure that both intensity controls are switched to off
position.
2. Slide the battery compartment cover and remove.
