What is T.E.N.S.?
The initials T.E.N.S. are short form for Transcutaneous Electric Nerve Stimulation which is what a T.E.N.S. machine actually does. A T.E.N.S. machine stimulates nerves electrically by transmitting current through the skin (Cutaneous tissue of Transcutaneous). Now through modern medical technology it may be possible to relieve some types of pain by utilizing the T.E.N.S. method of durgless pain relief. T.E.N.S. is an adjunct to post traumatic acute pain.
Now, through modern medical technology, electrical stimulation may be used at home conveniently and safely. The T.E. N.S. unit is effective, drugless, painless proven, convenient, portable, and inexpensive. T.E.N.S. is an alternate of chronic and many acute pain conditions. In many clinical studies Transcutaneous Electrical Nerve Stimulation (T.E.N.S.) has proven to be one of the safest and most effective alternative to drugs in the treatment of some pain syndromes.
