What is TENS?
TENS (Transcutaneous Electrical Nerve Stimulation)
works by passing mild electrical impulses through
the skin, into the nerve fibres which lie below, via
electrode pads. TENS impulses help your body
produce its own pain killing chemicals, such as
‘endorphins’.
What can TENS be used for?
TENS can be used for many chronic and acute pain
conditions such as back pain, shoulder pain,
arthritis, sciatica, sports injuries, migraine, period
pain and post operative pain.

Using your Flexi TENS
The Flexi TENS has 4 TENS modes. Each has been
designed to provide a different sensation.
You can use any of the TENS modes to treat your
pain. The table below sets out a brief description of
the sensation each mode provides:
Mode A Tapping
Mode B Massage
Mode C Tapping massage
Mode D Extended burst
To commence treatment
Carefully peel the electrodes from the plastic
backing, using your forefinger and thumb. Place on
your body as shown in the diagrams (pages 8
and 9). The black and white squares represent
where to place the electrodes. If you wish to treat an
area of pain that is not indicated in the diagrams on
pages 8 and 9, then as a general rule the electrodes
can be placed over or around the area of pain.
Once the electrodes are positioned correctly, switch
the unit on. MODE A will start to flash on the screen.
Select the mode that you wish to use by pressing
the MODE key. Once you have selected your mode,
gradually increase the intensity using the arrow UP
key, until the sensation is comfortable. Intensity
can be reduced by using the arrow DOWN key.
