TENS Therapy
In TENS therapy, electrodes are placed on the skin, either directly over the painful area or more commonly, at key points along the nerve pathway. A small, battery-powered generator emits a milli-amp (one thousandth of an ampere) of electricity through lead wires to the electrodes.
TENS is used to relieve pain. The sensation produced by the electrical stimulation appears to "override" the pain messages and may stimulate the body to produce its own natural morphine-like substance, which minimizes pain.
In the past two decades, TENS has been used for a wide variety of complaints. TENS has been applied to almost every type of pain, from mildly persistent problems (such as sore muscles) to acute postoperative pain and even in the pain of childbirth. The most common reason for prescribing TENS is for chronic low-back pain.
One of the most compelling reasons for prescribing TENS for pain relief is that this therapy has few side effects. TENS is non-addictive, causes no drowsiness, and can be used indefinitely without the problems associated with prolonged drug use.
