GENERAL DESCRIPTI N
The V-806 Digital T NS/ MS is a battery operated pulse generator that sends electrical
impulses electrodes to the body and reach the nerves and underlying muscle group. This
unit is a combination stimulator of T NS and MS which can be used for muscle
stimulation and pain relief. The device is provided with four controllable output channels,
each independent of each other. An electrode pair can be connected to each output
channel. The intensity level is controlled by press buttons.
INTR DUCTI N
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.
ven 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, analysed, 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 cord to the brain. The pain message
is then interpreted, referred back and the pain is felt.
EXPLANATION OF TENS
Transcutaneous lectrical Nerve Stimulation is a non-invasive, drug-free method of
controlling pain. T NS uses tiny electrical impulses sent through the skin to nerves to
modify your pain perception. T NS does not cure any physiological problem; it only helps
control the pain. T NS does not work for everyone; however, in most patients it is effective
in reducing or eliminating the pain, allowing for a return to normal activity.

INTR DUCTI N
There is nothing “magic” about Transcutaneous lectrical Nerve Stimulation (T NS). T NS
is intended to be used to relieve pain. The T NS 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
lectrical 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.
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.
The MS 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 MS 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 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.
