- Stands for:
- Transcutaneous electrical nerve stimulation
- -A pocket size, battery-operated device that provides mild, continuous electrical current through the skin by using 2 to 4 electrodes
-High TENS (100-500Hz) relieves pain by blocking pain fibers and is used up to 24 hrs/day because when the unit is turned off the pain cycle often returns.
-Low TENS (1-50Hz) relieves pain by endorphin release, and due to the 4 hour 1/2 life of endorphins need only be used 15-30 min at a time.
