1.1 Introduction

The LT3011A Ref.LTK545 is a battery operated pulse
generator that sends electrical impulses to the body and
reach the nerves and underlying muscle group,this is a unit
to be used for pain relief,muscle stimulation and
massage.The device provides two controllable output
channels,each independent of each other,a pair of
electrodes can be connected to each output channel.The
parameters of units are controlled by button.Its intensity
level is adjustable according to the needs of patients.

1.2 Medical background

What is TENS?

TENS (Transcutaneous Electrical Nerve Stimulation) gives
good results in acute and chronic pain conditions of many
kinds. It is clinically proven and used daily by
physiotherapists, other caregivers and top athletes around
the world.
High-frequency TENS activates the pain-inhibiting
mechanisms of the nervous system. Electrical impulses
from electrodes, placed on the skin over or near the painful
area, stimulate the nerves to block the pain signals to the
brain, and the pain is not perceived. Low-frequency TENS
stimulates the release of endorphins, the body's natural
painkillers. TENS is a safe treatment method and has, in
contrast to drugs and other pain relief methods, no side
effects. It may be sufficient as the only treatment form, but it
is also a valuable complement to other pharmacological

1. Foreword

and/or physical treatments. TENS does not always treat the
cause of pain. Consult your doctor if pain persists.

How Does TENS Control Pain?

The device provides pain relief in two ways. The first is the
gate control method. When the body is injured, both pain
and non-pain impulses are sent to the brain from the ervous
system. These pulses travel through the cutaneous nerves
to the deeper, afferent nerves, and then to the spinal cord
and brain. Along the path are many areas referred to as
“gates,” which determine which impulses are allowed to
continue on to the brain. The gates prevent the brain from
receiving too much information too quickly. Since the same
nerve cannot carry a pain and a non-pain impulse at the
same time, the stronger, non-pain impulse from the device
“controls the gate.” The second method of pain control is the
endorphin release method. The device can be set to trigger
the body's natural pain killers, called endorphins. These
chemicals interact with receptors, blocking the perception of
pain. This is similar to the way the pharmaceutical drug
morphine works, but without the side effect associated with
morphine. No matter which pain control method is
employed, the Device has been proven useful in pain
management. By reading this manual and carefully following
the treatment instructions provided by your clinician, you
can attain maximum benefit from your device.

What is EMS?

EMS (Electrical muscle stimulation) is achieved by sending
small electrical impulses through the skin to the underlying
motor units (nerves and muscles) to create an involuntary

muscle contraction. Neuromuscular stimulation has many
uses beyond its traditional application to prevent disuse
atrophy.

How does EMS work?

Because the transdermal stimulation of nerves and muscles
may be accomplished by electrical pulses, this modality can
help prevent disuse atrophy. Accordingly, incapacitated
patients can receive therapeutic treatment to create
involuntary muscle contractions thereby improving and
maintaining muscle tone without actual physical activity.
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.

2.1 Indications for use

This device is used in following instance:

1) Symptomatic relief of chronic intractable pain, acute
post traumatic pain or acute post surgical pain.

2) Increase of blood flow in the treatment area.

3) Relaxation of muscle spasm.

4) Immediate post-surgical stimulation of muscles to
prevent venous thrombosis.

5) Prevention or retardation of disuse atrophy.

6) Muscle re-education

7) Maintaining or increasing range of motion.

2.2 Contraindications

1) This device should not be used when cancerous
lesions are present in the treatment area.

2) Stimulation should not be applied over swollen, infected,
inflamed areas or skin eruptions
(e.g. phlebitis, thrombophlebitis, varicose veins, etc.).

3) Safety has not been established for the use of
therapeutic electrical stimulation during pregnancy.

4) Demand type implanted pacemaker or defibrillator.

5) Epilepsy

6) Serious arterial circulatory problems in the lower limbs

7) Abdominal or inguinal hernia

8) No suitable for use during pregnancy or labor women

9) Do not use this device when pain syndromes are
undiagnosed. Use only after origin of pain has been
diagnosed.

The long-term effects of chronic electrical stimulation
are unknown.
For external use only.
This device should be used only under the continued
supervision of a licensed medical practitioner.
Stimulation should not be applied over the carotid sinus
nerves, particularly in patients witha known sensitivity
to the carotid sinus reflex.
Do not apply stimulation over thyroid or carotid sinus
region of the neck or mouth, or from electrodes placed
on the chest and the upper back, because this could
severe muscle spasms resulting in closure of the
airway, difficulty in breathing, or adverse effects on
heart rhythm or blood pressure.
Stimulation should not be applied transthoracically in
that the introduction of electrical current into the heart
may cause cardiac arrhythmias.
Stimulation should not take place while the user is
connected to high-frequency surgical equipment, it may
cause burn injuries on the skin under the electrodes, as
well as problems with the stimulator.
Do not use the stimulator in the vicinity of shortwave or
microwave therapy equipment, since this may affect the
output power of the stimulator.
Never use in environments with high humidity such as
in the bathroom or when having a bath or shower.
Never use near the heat. 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 can increase the

The stimulator is suitable for private use.
Caution should be used for patients with suspected or
diagnosed heart problems.
Some patients may experience skin irritation or
hypersensitivity due to the electrical stimulation or gel. If
rash develops or pain persists, discontinue use and
consult a doctor.
Electrode placement and stimulation settings should be
based on the guidance of prescribing practitioner.
Effectiveness is highly dependent upon patient selection

by a person qualified in the management of pain
afflicted patients.
Isolated cases of skin irritation may occur at the site of
the electrode placement following long-term application.
The electrodes are only to be placed on healthy skin.
Avoid skin irritation by ensuring that good contact is
achieved between electrodes and skin.
If the stimulation levels are uncomfortable or become
uncomfortable, reduce the stimulation amplitude to a
comfortable level and contact your physician if problems
persist.
The device may not be used whilst driving a car or whilst
operating and controlling machinery.
Never use the device in rooms where aerosols(sprays)
are used or pure oxygen is being administered.
Do not use it near any highly flammable substances,
gases or explosives.
Do not use this device at the same time as other
equipment which sends electrical pulses to your body.
Do not confuse the electrode cables and contacts with
your headphones or other devices, and do not connect
the electrodes to other devices.
Do not use sharp objects such as pencil point or
ballpoint pen to operate the buttons on the control panel.

risk of ventricular fibrillation and lead to cardiac arrest.
Never use on the eye area, or applied across or through
the head.
Never use near the genitals.
Never use on the areas of the skin which lack normal
sensation
This stimulator is never use by patients who have
noncompliant, emotionally disturbed, dementia, or low
IQ.
Apply the electrodes to clean, dry, and unbroken skin
only.
Keep electrodes separate during treatment, electrodes
