Pain Management: Treatment Overview
Transcutaneous electrical nerve stimulation therapy, more commonly referred to as TENS, uses electrical stimulation to diminish pain. During the procedure, low-voltage electrical current is delivered through electrodes that are placed on the skin near the source of pain. The electricity from the electrodes stimulates the nerves in an affected area and sends signals to the brain that "scramble" normal pain signals.TENS is not painful and may be effective therapy to mask pain such as diabetic neuropathy. However, TENS for chronic low back pain is not effective and cannot be recommended, says the American Academy of Neurology (AAN).
Bioelectric therapy relieves pain by blocking pain messages to the brain. Bioelectric therapy also prompts the body to produce chemicals called endorphins that decrease or eliminate painful sensations by blocking the message of pain from being delivered to the brain.
Bioelectric therapy can be used to treat many chronic and acute conditions causing pain, such as back pain, muscle pain, headaches and migraines, arthritis, TMJ disorder, diabetic neuropathy, and scleroderma.
Bioelectric therapy is effective in providing temporary pain control, but it should be used as part of a total pain management program. When used along with conventional pain-relieving medications, bioelectric treatment may allow pain sufferers to reduce their dose of some pain relievers by up to 50%.
Physical therapy helps to relieve pain by using special techniques that improve movement and function impaired by an injury or disability. Along with employing stretching, strengthening, and pain-relieving techniques, a physical therapist may use, among other things, TENS to aid treatment.
Although resting for short periods can alleviate pain, too much rest may actually increase pain and put you at greater risk of injury when you again attempt movement. Research has shown that regular exercise can diminish pain in the long term by improving muscle tone, strength, and flexibility. Exercise may also cause a release of endorphins, the body's natural painkillers. Some exercises are easier for certain chronic pain sufferers to perform than others; try swimming, biking, walking, rowing, and yoga.
