1. GENERAL INFORMATION
1.1 General Description
The TENS 3000 is a battery operated pulse generator that sends
electrical impulses electrodes to the body and reach the nerves
causing pain. The device is provided with two controllable output
channels, each independent of each other.
The electronics of the TENS 3000 create electrical impulses whose
Intensity, duration, number per second and modulation may be
altered with the controls or switches. Dial controls are very easy to
use and the slide cover prevents accidental changes in the setting.
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 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 non-invasive,
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 the pain,
allowing for a return to normal activity.
