2. MEDICAL BACKGROUND
WHAT IS TENS?
TENS = Transcutaneous Electrical Nerve Stimulation. TENS is an effective method offering Pain Relief.
TENS utilises the nervous system’s own pain relief mechanisms to ease both acute and chronic pain.
WHEN IS TENS USED?
Good results are observed in acute and long-term pain conditions of many kinds, but above all when the
pain originates in joints, the skeleton, muscles, skin, viscera, or nervous system. In some cases, TENS
on its own may be sufficient, and in other cases it may provide a valuable complement to other forms of
treatment.
HOW DOES IT WORK?
With the Pain Relief programs, impulses are sent through the nerves to block the pain impulses. Pain
Relief is usually most efficient during stimulation, but the effect can also last after the program has finis-
hed. It also increases the circulation. The Pain Relief programs do not always treat the cause of pain. If
the pain persists, seek medical advice.
WHEN AND HOW SHOULD I USE TENS?
The programs in the CEFAR BASIC can be used on any occasion when Pain Relief or Muscle Relaxation is
needed. All the programs can be used as often as required. Guidelines for using the treatment programs
with indication examples, suggested electrode placements and recommended treatment time are included
in this manual.
