8INTRODUCTION TO TENS
What is TENS?
Transcutaneous electrical nerve stimulation is a pain control treatment. It is often called TENS for short.
A TENS unit is a portable, pocket-sized, battery-powered device.
The TENS unit uses mild, safe electrical signals to help control pain and delivers the electrical signal to the body through
self-adhesive conductive electrodes.
How does TENS work?
The most common TENS programmes use
high-frequency stimulation, which is the rst choice for
both acute and chronic pain. High-frequency stimulation
sends impulses to the nervous system’s own
pain-inhibiting mechanisms, which block the pain.
You can use it as often and as long as you like, but each
treatment should last at least 1 hour.
Another type of TENS is low-frequency stimulation.
Low-frequency TENS treatment can alleviate pain
by stimulating muscles to release the body’s own
morphine-like substances, endorphins.
Place the electrodes on a muscle in the painful area so
that a visible contraction occurs.

Turn Stimulator OFF before applying or removing electrodes
Application of the self-adhesive pads & aftercare
The electrode pads have a maximum usage of 25-30 applications to keep your pads in good condition apply a small
amount of water to the gel side of the pad every 4th application (do not over wet). Do not apply any gels or creams to
the pads as this will destroy the hydro-gel on the electrode pad.
Application
1. Skin site must be very clean and dry, dirty, aky or oily skin will prevent electrodes from adhering to the skin. If
necessary, trim excess hair with scissors. If skin is oily wipe down with an alcohol or electrode skin prep prior to
application. Be sure to wash hands before handling electrodes.
2. Remove electrodes from bag and reseal bag to protect remaining electrodes.
3. Insert the stud electrode on to the back of the device.
4. Grasping a tiny edge of the electrode, peel and remove electrode from the protective plastic liner. Save liner for
electrode storage.
5. Place electrode onto skin treatment site (as recommended by your clinician) by rmly applying from the center of the
electrode to the outer edges. Adhesion improves when electrodes reach skin temperature.
6. If gel appears over-saturated with excessive moisture or perspiration, allow the electrode to air dry in a refrigerator
with the gel side facing up until the gel regains its tack. If the gel appears dry, try adding a few drops of water to the
gel and allow to rest in a dust-free environment until the gel regains its tack.
ELECTRODE INSTRUCTIONS FOR USE

19
ELECTRODE INSTRUCTIONS FOR USE
