1. Safety information
1.1 Product Description
Neo TekTM Combo Stimulator is a portable electrotherapy device featuring 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 groups via electrodes applied to the skin. The parameters of
the device are controlled by the buttons on the front panel. The intensity level
is adjustable according to the needs of each individual patient.
1.2 Indications for use
The Neo TekTM Combo Stimulator (TENS and EMS) may be used for the
following conditions.
For TENS mode
1. Symptomatic relief of chronic intractable pain
2. Post traumatic pain
3. Post surgical pain
For EMS mode
1. Relaxation of muscle spasms
2. Increase of local blood ow circulation
3. Prevention or retardation of disuse atrophy
4. Muscle re-education
5. Maintaining or increasing range of motion
6. Immediate post-surgical stimulation of calf muscles to prevent venous
thrombosis
1.3 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

5
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 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 dierent nerves that travel up the spinal cord to the brain. The
pain message is then interpreted, referred back and the pain is felt.
HOW TENS STIMULATOR FOR PAIN RELIEF WORKS
What is it?
The Neo TekTM Combo Stimulator is a two output channel TENS machine and
highly eective in relieving pain. TENS is now regularly recommended by
doctors, physiotherapists and pharmacists throughout the world.
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 eective in reducing or eliminating
the pain, allowing for a return to normal activity.
How TENS works?
Scientic theory suggests that electrical stimulation therapy may work in
several ways:
1) The gentle electrical pulses move through the skin to nearby nerves to
block or shut out the pain message from ever reaching the brain from the
source of the pain.
2) The gentle electrical pulses increase the production of the body’s natural
pain killer, such as endorphins.
3) Furthermore, it is thought that the electrical stimulation improves blood
circulation as well. Muscles contract and relax with the ow of the electrical

6
stimulation. With repeated contracting and relaxing, the blood ows in and
out and the blood circulation is improved.
HOW EMS STIMULATOR FOR MUSCLE STIMULATION WORK
What is it?
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 (ladder‐shaped). 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 aected muscles
and improving muscle tone and blood circulation.
How EMS works?
The EMS unit sends 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 exes as in physical exercise. Then when the pulse ceases, the muscle
relaxes and then the cycle is continuously 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 specically targeted muscle, which reacts by
contracting, just as it does with normal muscular activity.
