INTRODUCTION
How does TENS work?
TENS is a non-invasive and drug-free method of treating pain. The
TENS unit transmits soothing electrical pulses through the skin that
stimulate the nerve (or nerves) in the area being treated. In most
cases, this stimulation greatly reduces or even completely eliminates
the sensation of pain, as it blocks the original pain signals to the
brain.
It is also reported that TENS stimulation promotes the release of
endorphins into the bloodstream, leading to a further reduction in
pain.
The benefits of TENS devices in pain management have been cli-
nically proven in the case of many patients. To get the most out of
your TENS unit, read these instructions carefully and follow your
doctor's recommendations for treatment.
All information, general sensations, skin sensations, deep sensi-
bility, is relayed to the CNS (central nervous system) via the nerve
pathways.
The classic TENS method interrupts pain transmission for an
indefinite period of time.
It does not affect the source of pain locally, but acts exclusively
on the nerve tissue.
Nerve tissue can be stimulated by electrical current over a wide
spectrum of frequencies.
Because of the interaction between the stimulation frequency and
the transmission speed of the nerve fibers, it can be seen that
different frequencies selectively activate certain types
of nerve.
