TENS stands for trancutaneous electrical nerve stimulation. A TENS machine relieves back pain through electrical pulses delivered to the body. The devices are used in medical facilities by physical therapists, or portable may be used at home with proper instructions.
History
Dr. Patrick Wall and Dr. Ronald Melzac created a theory in 1965 called the Gate Control Theory. They claimed that when a gate mechanism is closed off in the spinal cord, it prevents pain signals from being felt. Soon after the TENS machine was developed on this theory of electrical pulses interrupting pain signals and the device was used extensively by the 1970s.
TENS Machine
A TENS machine is a small electrical device with two electrodes. The electrodes are placed on the back where pain is occurring. When the TENS machine is turned on, the patient will feel a tingling sensation as small electrical currents are delivered through the electrodes. Sessions last anywhere from five to 45 minutes, depending on the severity of the pain.
Benefits
A TENS machine used for back pain relief is a non-invasive type of treatment. The electrical stimulation encourages endorphin production, which is needed to block pain signals to the brain. There are no medications to take and a portable unit allows freedom in taking the device with you to work or on vacation. The TENS machine is easy to use and small enough to put in a pocket or purse.
Complications
Complications of using a TENS machine for back pain relief include skin irritation where the electrodes are placed, and problems from turning the electrical current up too high. An intense electrical current may cause burning to the skin. Those with high risk of heart disease and pregnant women should not use a TENS machine. People with pacemakers, infusion pumps and defibrillators should not use equipment with electrical currents as they can disrupt the proper functioning of these medical devices.
Considerations
The TENS machine works well for people with mild or moderate back pain, but may not be of much help to those with chronic or severe pain. While the machine helps with pain, it does not treat the underlying condition for the pain. It is important to see your doctor to determine what medical condition is related to your back pain and seek treatment for those symptoms also.
