More Information about TENS

Although the Tens Units, short for Transcutaneous Electrical Nerve Stimulation, may seem like a fairly recent invention, the principles they use date back to nearly five thousand years ago. The first mentions of applying small electric shocks in order to relieve pain can be found in ancient Greek and Egyptian manuscripts, when the healers used electric eels found in the nearby rivers. However, the technology has come a long way since then and the modern units have a lot of settings, such as mode, pulse width and rate or electrical output intensity, making it easy to adjust to every person’s needs.

The uses of Tens

Tens Unit being used for lower back painThe Transcutaneous Electrical Nerve Stimulation Units are a common solution for people that are experiencing chronic pain due to injury related problems such back pains, muscle pains or peripheral nerve pains. However, the Tens Unit works just as well for acute pains like for example headaches, menstruation related aches or post-childbirth pain.

What you need to know about these devices is that they will not solve the problems or cure the illnesses that cause the pain, but merely provide a temporary relief, much in the same way painkillers do. The Transcutaneous Electrical Nerve Stimulation Units are a non-invasive method that has been given a lot of attention lately. While no hard evidence linking Tens Units with pain suppression has been found, clinical tests show significant improvements for an astounding percentage of the patients that have used them.

As many of the world famous neurologists have stated, the mere fact that the connection between electrical nerve stimulation and pain relief cannot be proven yet does not mean that the obvious effectiveness of this method should be discarded.

Basic principles of the Tens Unit

This device is basically a small portable battery that is used to short circuit the transmission of painful signals from the nervous system to the brain via the electrodes placed on the body. In order for the Tens Unit electrodes to be effective, they need to be set in the proximity of the painful body areas.

Transcutaneous Electrical Nerve Stimulation is also known to cause an increase in the serotonin production and other various endorphins, which act as the body’s own analgesics. This is in addition to inhibiting the signal transmission of an overexcited nerve to the brain, thus suppressing the intensity of the pain sensation.

The Tens Unit electrode placement should be performed under medical supervision, in accordance to the placement chart.

Therapy options

Tens Device being used to provide neck pain reliefThere are two settings available on standard devices of this nature, based on the Tens Unit therapy that your doctor recommends for your situation.

Using a higher frequency, between forty and one hundred and fifty hertz, and of lower impulses, between ten and thirty ma, the first therapy method implies that the electrodes will be kept on for the entire time. The unit is turned on for about thirty minutes at a time and the analgesic effect will persist for a while after it is turned off, varying from patient to patient.

The acupuncture therapy option is based on a lower frequency transmission of high intensity impulses, according to the pain threshold of each person. Though it is more efficient than the previous therapy method, a lot of people are not able to tolerate it very well and it should be used only if the first one is not giving any results.

Possible side effects

As far as the conducted studies so far have proven, there are no serious complications that result from continued use. This non invasive analgesic method presents very little risks and has shown no interaction with pain medication. In fact, limiting the amount of medication that the patients suffering from chronic pains need to use can be quite beneficial for the body.

However, since the Tens Unit therapy causes cell death, it is advisable to change positions of the electrodes a little bit every time you apply them, giving the areas time to regenerate the cells. The damage caused by the electrodes is insignificant and it presents no threat to your health.
Some patients experienced mild rashes in the nearby area of the electrodes. This effect is mostly caused by the gel used to balance the impedance of the skin after a few applications and can be easily fixed by changing it.

Cases when you should not use a Tens

There are a few situations when they should not be used. People who depend on pacemakers for a proper heart functioning should avoid, as the electrical impulses generated may lead to malfunctions of the pacemakers.

The Transcutaneous electric nerve stimulation should also be avoided by pregnant women. Since the unit will be set to meet the requirements of the adult body, the intensity is far higher than the baby should be exposed to, thus creating unpredictable results.

The electrodes should not be applied directly on open wounds or on nearby tumors.  At the same time, do not place them close to the eyes, as the electric flow will increase their internal pressure.

Before opting for the therapy, you should consider checking with your doctor and verify that you are given the green light to do so.


In order to get the best results from your Tens Unit, you need to respect all the indications that your doctor and its manufacturers provide you with. If you use it properly, the Transcutaneous Electrical Nerve Stimulation can be a very good solution to your chronic or acute pain problems and can replace your traditional medication.

However, bear in mind that the Tens Unit pain relief is not a treatment for the illness that causes the pain in the first place. All this device does is help you cope with the symptoms, so you will still need to follow the treatment for the actual disease or injury.
