1.Safety information
1.1 General
InTENSityTM Twin Stim III
two
therapeutic modes: Transcutaneous Electrical Nerve Stimulator
(TENS) and Electrical Muscle Stimulation (EMS), 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 buttons on the front panel. The 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 the 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
is a portable electrotherapy device featuring
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 most patients it is effective in reducing or eliminating
5
the pain, allowing for a return to normal activity.
HOW TENS WORKS
There is nothing “magic” about Transcutaneous Electrical Nerve
Stimulation (TENS). TENS is intended to be used to relieve pain.
The TENS unit sends comfortable impulses through the skin that
stimulate the nerve (or nerves) in the treatment area. In many
cases, this stimulation will greatly reduce or eliminate the pain
sensation the patient feels. Pain relief varies by individual patient,
mode selected for therapy, and the type of pain. In many patients,
the reduction or elimination of pain lasts longer than the actual
period of stimulation (sometimes as much as three to four times
longer). In others, pain is only modified while stimulation actually
occurs. You may discuss this with your physician or therapist.
EXPLANATION OF EMS
Electrical Muscle Stimulation (EMS) 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. 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 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
The EMS units send comfortable impulses through the skin that
stimulate the nerves in the treatment area. When the muscle
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. Then when the pulse ceases, the muscle
relaxes and the cycle is repeated. The goal of electrical muscle
stimulation is to achieve contractions or vibrations in the muscles.
Normal muscular activity is controlled by the central and
peripheral nervous systems, which transmit electrical signals to
the muscles. EMS works similarly but uses an external source
(the stimulator)with electrodes attached to the skin for transmitting
electrical impulses into the body. The impulses stimulate the
nerves to send signals to a specifically targeted muscle, which
reacts by contracting, just as it does with normal muscular activity.
1.3 Indication for use
InTENSityTM Twin Stim III

3) Post surgical pain.
For Electrical Muscle Stimulation / Neuromuscular Stimulation
therapeutic mode (EMS):
1) Relaxation of muscle spasm.
2) Increase of blood flow circulation.
3) Prevention of disuse atrophy.
4) Muscle re-education.
5) Maintaining or increasing range of motion.

prevent venous thrombosis.
IMPORTANT SAFETY INFORMATION!
Read the instruction manual before operation. Be sure to comply
with all “Contraindications”, “Warnings”, “Cautions” and “Adverse
reactions” in the manual. Failure to follow instructions can cause
harm to user or device.

CAUTIONS:
out of reach of children.
you are in any doubt whatsoever.
13) Some patients may experience skin irritation or
hypersensitivity due to the electrical stimulation or silicone
rubber. If rash develops or pain persists, discontinue use and
consult a doctor.
14) Electrode placement and stimulation settings should be based
on the guidance of prescribing practitioner.
15) Effectiveness is highly dependent upon patient selection by a
person qualified in the management of pain afflicted patients.
16) Isolated cases of skin irritation may occur at the site of the
electrode placement following long-term application. If this
occurs, discontinue use and consult your physician.
17) The electrodes are only to be placed on healthy skin. Avoid
skin irritation by ensuring that good contact is achieved
between electrodes and skin.
18) If the stimulation levels are uncomfortable or become
uncomfortable, reduce the stimulation Intensity to a
comfortable level and contact your physician if problems
persist.
19) This device should not be used while driving, operating
machinery, close to water, or during any activity in which
involuntary muscle contractions may put the user at undue risk
of injury.
20) Never use the device in rooms where aerosols (sprays) are
used or pure oxygen is being administered.
21) Do not use it near any highly flammable substances, gases or
explosives.
22) Do not use this device at the same time as other equipment
which sends electrical pulses to your body.
23) Do not confuse the electrode cables and contacts with your
headphones or other devices, and do not connect the
electrodes to other devices.
24) Do not use sharp objects such as pencil point or ballpoint pen
to operate the buttons on the control panel.
25) Inspect Applicator cables and associated connectors before
each use.
26) Turn the device off before applying or removing electrodes.
27) Electrical stimulators should be used only with the leads and
electrodes recommended for use by the manufacturer.
28) This device has no AP/APG protection. Do not use it in the
presence of explosive atmosphere and flammable mixture.
