OPERATING INSTRUCTIONS FOR PHYSICIAN

INTENDED USE

T. E. N. S. Stands for (Transcutaneous Electrical
Nerve Stimulation). This T.E.N.S. system is used to
provide symptomatic pain relief for chronic, acute or
post-operative pain.

HOW DOES T.E.N.S. WORK

T.E.N.S. is believed to work by stimulating your
body's own natural defenses against pain.
The unit produces a gentle stimulus through pads
normally placed over the area of pain. This stimulus
helps the body to produce natural pain relievers
called endorphins.
The correct positioning of the pads is important.
Some people feel immediate benefit from T.E.N.S.
However some may only achieve benefit after
repeated treatment sessions and over an extended
period of time.
