Transcutaneous electrical nerve stimulation, other wise known as TENS, is a therapy that utilizes low voltage electrical current in order to relieve pain. TENS is performed using a little battery powered mechanism that is about the size of a pocket radio. Generally, two electrodes are connected from the machine to your skin. The electrodes are placed in the area of pain or at a pressure point, forming a circuit of electrical impulses that travels through nerve fibers.

When the current is administered, some individuals experience less pain. This may be due to the electricity which sends signals to the brain, blocking the normal pain signals. Another possibility is that the electrical stimulation of the nerves may aid the body in producing natural painkillers known as endorphins.

The TENS machine has different settings that allow an individual to utilize a steady flow of electrical current or a burst of electrical current. Your therapist, acupuncturist, or doctor usually decides what setting to implement.

TENS is used to relieve pain caused by a variety of illnesses and conditions. It is usually used to treat muscle, joint, or bone problems that are caused by osteoarthritis or fibromyalgia or for conditions including back pain, neck pain, tendinitis, or bursitis. People have also tried using TENS to treat acute pain, as well as chronic pain caused by cancer.

It is generally agreed that TENS is safe, though the mechanism may cause harm if not used correctly. It is important to have your physical therapist or doctor instruct you on how to use the device correctly.
