How "Tens" Works - TensCare perfect mamaTENS Manual Del Usuario

Intensity returns to zero if the electrode
pads come loose. Zeros will flash on the
screen until connection
established.
• Keypad Lock
Enables the user to manually lock the
controls to prevent any accidental
changes in settings.
• Belt Clip and Neck Cord
A belt clip and a neck strap allow you to
attach the unit to your clothing or your
neck; neck cord has a quick-release
system for safety if pulled.
Note: The electrode pads need
to be applied directly to the skin
before the intensity increase buttons
will operate. If the perfect mamaTENS
detects the unit
connected to you (for example if the
electrode pads or leads come loose)
then the unit switches the intensity to
zero. This safety feature prevents any
unpleasant changes in output.

4. HOW "TENS" WORKS

T.E.N.S. stands for Transcutaneous
Electrical Nerve Stimulation. T.E.N.S.
stimulates your body's own natural
defences against pain, namely the
release of endorphins. TENS is totally
safe and has been used successfully by
thousands of pain sufferers.
TENS sends a gentle stimulation
through the skin which works in
TWO ways:
is re-
is not properly

Pain Gate
It stimulates the
sensory nerves,
which carry touch
and temperature
signals. These
nerves go to the
same connections
in the spine as the nerves carrying pain.
A strong sensory signal will block the
pain signal travelling up the spine to the
brain. This is known as closing the
"Pain Gate" and takes effect quite
quickly after the unit is switched on.
When the gate is open, pain messages
get through to the brain and we feel
pain. When the gate is closed, these
pain messages are blocked and we do
not feel pain.
Evidence suggests that TENS produce
pain relief in a similar way to 'rubbing
the pain better'. The pain gate can be
closed by
mechanoreceptors through 'rubbing the
skin'.
Scientifically, the pain gate works by
release of chemical in the synapse at
spinal level that inhibits transmission of
pain signal.
Endorphin Release
At low frequency
settings, and
slightly stronger
outputs, TENS
drives the motor
nerves to produce
a small repetitive
muscle
contraction. This is seen by the brain as
exercise, and this promotes the release
of endorphins - your body's own natural
pain killer. The relief builds up and
normally takes about 40 minutes to
activation of
