What is TENS pain relief and how does it relate to someone in pain? TENS is an acronym for a transcutaneous electrical nerve stimulation unit. A TENS unit is a portable, pocket-sized, battery-powered device that uses mild, safe electrical signals to help control pain. One of these units can treat many kinds of pain. A modern TENS pain unit is easy to use and compact enough to provide quick and dependable pain relief at work, home or play.
The electrical signals travel from the TENS unit through wires to the electrodes which are attached to your body. The electrode wires are then plugged into the unit. The unit is then hooked to your belt or placed in a pocket. For some chronic pain patients, TENS pain relief can last for several hours. For others, a TENS pain unit may help reduce the amount of pain medications needed.
A TENS pain unit is one of several kinds of electrotherapy devices that use very small doses of electric current to promote natural pain relief. A typical battery-operated TENS unit is able to modulate pulse width, frequency and intensity. When the unit is turned on, it delivers a light current through the electrodes to the skin and tissues just beneath it.
The unit emits low – voltage electrical pulses through electrodes attached to the body. The TENS unit works by preventing pain signals from reaching your brain. Depending on the frequency the unit delivers, the electrical stimulation can also trigger the body to release endorphins, which are natural pain killers. A physical therapist can help you determine the most appropriate settings for your unit.
Do not turn your TENS unit up too high as this can cause over-stimulation which may make pain worse. Do not get into water or sleep with the electrodes on your skin and the TENS unit turned on. If you wear a pacemaker check with your physician before using a TENS unit as this may interfere with the pacemaker’s function.
TENS units can be purchased or rented. The cost of a unit can range from about $100 to several hundred dollars. A TENS pain unit should only be used under the direction of a doctor, physical therapist, or occupational therapist.
If you suffer from chronic back pain, arthritis, tendinitis, aches and pain, poor circulation, sciatic nerve pains, headaches, migraines and other discomforts a TENS unit may help relieve some of your pain. TENS pain relief is not a cure, it simply gives the impression of experiencing less pain. These units are widely used in the physical therapy field to help patients control their pain while they rehabilitate their muscles. TENS pain relief units are considered safe when used properly and have helped many people.
