Transcutaneous electrical nerve stimulators, or tens machines, are integral tools in most chiropractic and physical therapy practices. Most patients' chronic pain can be effectively treated by using a tens machine on a regular basis. Patients can usually avoid expensive and invasive surgery or addictive pain medication, too.

Tens machines transmit an electrical current through a patient's affected areas. The electrical current is transmitted through electrodes that are affixed to the skin. The current produces a tingling sensation that in turn influences pain pathways. Ideally, the electrical current will block pain receptors in the brain, and the patient will feel his or her pain lessening, often after half an hour.

The spinal cord is part of the central nervous system and together with the sensory nerves, it sends pain signals to the brain. The central idea behind electrotherapy is that by interfering with pain signaling, doctors can alleviate their patients' discomfort. Tens machines allow you to adjust the amount of current to find the optimal levels for each patient. Depending on the frequency of the pulse, it is also possible to use electrical current to trigger endorphins, thereby providing additional pain relief.

Finding Tens Machines Online

The best way for any practice to locate a new or used tens machine is to go online. Some office managers or procurement specialists may be hesitant to do this the first time; however, there's a simple way around any doubts you may have. Visit an online vendor and take notes on the prices and brands they offer. Then, visit your regular brick-and-mortar vendor and compare prices. In person, take the opportunity to look at the equipment and pick the right model for you. Tens units are proven effective for the relief of pain, and are a great alternative to addictive painkillers or other drugs. These units are safe, non-invasive, and FDA-regulated. They are only available by or on the order of a physician, as mandated by federal law.
