TENS
  Transcutaneous Electrical Nerve
Stimulation, more commonly referred to as a "TENS," is defined by the
American Physical Therapy Association as the application of electrical
current through the skin for pain control. The TENS unit is connected
to the skin using two or more electrodes. A typical battery-operated
TENS unit is able to modulate pulse width, frequency and intensity.
Generally TENS is applied at high frequency (>50 Hz) with an
intensity below motor contraction (sensory intensity) or low frequency
(<10 Hz) with an intensity that produces motor contraction.
TENS
machines help to relieve pain by passing a small electrical current
through the skin which helps to block the pain messages from the pain
nerves which lie deeper in the muscles and tissues below this area. The
pulsating current, and the frequency and power of the current can have
a great effect on the resulting pain relief, and most TENS machines
give you some control over these factors.
